A Framework for Ranking of Colleges Based on Unstructured Data using k-Anonymity Algorithm in Hadoop.
Choosing a right measure in assessing the education system might be a great challenge in present scenario. As the numbers of technical institutions are increasing enormously, students and parents are uncertain to take up higher education in a reputed institution. The information regarding colleges or institutions is graded by many institutional stake holders and others through social networking sites like Twitter. The large volume of data generated through social networking sites is unstructured which is posted by different kinds of people. Processing the unstructured data is a tedious process. To rank the institutions based on the unstructured data would be a difficult process using traditional or conventional data mining techniques and tools. The proposed framework is for ranking the institutions based on K-anonymity algorithm which is implemented in HADOOP and HIVE. This method improves the efficiency and accuracy of the data processing compare to the traditional methods. - See more at:

Determining required heat energy and CO2 emissions resulting from fuel consumption in different greenhouse installations in Mediterranean climate conditions -
As a result of the energy crises of the 1970s, greenhouse cultivation has developed rapidly in the countries on the Mediterranean coast. In order to achieve the expected quality production and productivity, greenhouses should be heated when outside temperature falls below 12oC. In Turkey, small scale family businesses implement very simple heating methods to protect plants from frost, rather than provide regular heating of greenhouses. The modern greenhouses that have been installed in recent years are equipped with hot water tube heating systems. In addition to affecting production costs in a significant way, heating greenhouses has negative influence on the environment due to carbon emissions of the selected fuel type. The fuel to be used in heating greenhouses should be both cost effective and environment friendly with the lowest level of carbon emissions. This study aims to determine the amount of heating energy required for different inside temperature values desired in plastic greenhouses with different specifications, under Mediterranean climate conditions, to estimate the amounts of coal, natural gas, diesel fuel and fuel oil to be used in heating and to calculate the annual fuel costs and carbon dioxide (CO2) emissions for each fuel type. The study has shown that the most convenient fuel to meet the annual heat requirements of greenhouses is natural gas. The relative change in the cost of natural gas, diesel fuel and fuel oil has been calculated as an increase of 13%, 73% and 59% respectively. The annual CO2emission of natural gas has been determined to be 50%, 29% and 30% lower than that of coal, diesel fuel and fuel oil respectively. - See more at:

The Role of Serum Procalcitonin Levels in Predicting Ascitic Fluid Infection in Ascitic Patients Admitted to Zagazig University Hospital in 2014.
Background: It is difficult to diagnose spontaneous bacterial peritonitis (SBP) early in ascitic patients. The aim of the study was to measure serum procalcitonin (PCT) levels to obtain an early diagnostic indication of SBP in ascitic patients. Methods: A total of 62 patients (mean age: 54.4 ? 10.7, 77.4% were males) hospitalized due to cirrhosis (n=57) or non-cirrhosis related (n=5) ascites were included in this study. Spontaneous bacterial peritonitis (SBP, 19.4%), culture-negative SBP (35.5%), bacterascites (6.5%), sterile ascites (30.6%) and non-cirrhotic ascites (8.1%) groups were compared in terms of procalcitonin levels in predicting ascites infection. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic performance of procalcitonin levels. Results: Culture positivity was determined in 25.8% of overall population. Serum procalcitonin levels were determined to be significantly higher in patients with positive bacterial culture in ascitic fluid compared to patients without culture positivity (median (min-max): 3.35 (0.05?6.4) vs. 0.2 (0.05-1.9), p=0.000). Using ROC analysis, a serum procalcitonin level of >1.9 ng/mL (area under curve (AUC): 0.791, sensitivity: 75%, specificity: 100%, positive predictive value 100% and negative predictive value 92%) were determined to accurately help the diagnosis of bacterial peritonitis. Conclusion: According to our findings, determination of serum procalcitonin levels seems to provide accurate and rapid diagnosis of ascitic fluid infection - See more at:
A new method for the determination of dissociation constant (kd) on the binding of CA19-9 to its antibody in type 2diabetic patients by enzyme linked immunosorbent assay (ELISA) with some modifications.
Background:-In order to quantify the interactions between molecules of biological interest, the determination of dissociation constants (Kd) is essential. Several methods are known for calculating these constants, most of which are based on linearization procedures, such as the Scatchard (1949) plot, Lineweaver and Burk (1934) plot, etc. This linearization does not require direct ligand labelling or the absolute concentration of the complex and is, therefore, especially suitable for Kd determination from an enzyme-linked immunosorbent assay (ELISA). Objectives: - Present a new method for the determination of a dissociation constant (Kd) of the binding of CA19-9 to its antibody in type 2 diabetic patients using Scatchard plot through development of ELISA. Methods:- This study included eighty individuals with mean age (46.5 ? 1.14 years) were divided into two groups. Group Ⅰ,forty patients with type Ⅱ diabetes mellitus have a mean duration 6.6? 0.94.Group Ⅱconsisted of forty healthy individuals were classified as control group. CA19-9 level were measured in serum by ELISA technique.Select the highest value from the first group and other value within the normal range chosen from the second group in addition to the CA19-9 standard (100U/ml) to determine the dissociation constant (kd) using external CA19-9 monoclonal antibody and calculated by Scatchard plot. Results:- The dissociation constant of the interaction between antibody and antigen from the data of direct, non-competitive enzyme linked immunosorbent assays (ELISA) by Scatchard plot is (15.6006, 12.5313 and 4.1271 U/ml) for Standard (100 U/ml), Patient (99.568 U/ml) and Control (23.494 U/ml) respectively. Conclusion:-A simple linearization procedure developed to determine the dissociation constant of the interaction between antibody and antigen from the data of direct, non-competitive enzyme linked immunosorbent assays (ELISA) by Scatchard plot. -See more at:

DIRECT SPECTROPHOTOMETRIC DETERMINATION OF URANIUM IN GRANITE AFTER ITS SELECTIVE LEACHING USING LIXIVIANT REAGENTS WITHOUT ITS PRIOR SEPARATION.
A spectrophotometric determination of uranium in microgranite rock sample, Sela area, South Eastern Desert, Egypt, from its leach liquor using effective and efficient lixiviants for its selective leaching followed by its direct spectrophotometric determination using arsenazo (III) dye without prior separation, as solvent extraction or ion exchange, was proposed in the present work. Several lixiviants were studied for the selective leaching of uranium namely; citric acid, urea, ammonium acetate, ammonium carbonate, ammonium bicarbonate and ammonium nitrate. The selected ammonium bicarbonate and ammonium nitrate lixiviants gave high leaching efficiency of uranium beside the minimal dissolution concentrations of the concomitants hence lowering the matrix interfering effect of those elements during its determination. Several factors were studied for this purpose namely; the choice of proper lixiviant(s), solid to liquid ratio (S/L), leaching time, temperature, interfering matrix effect where their spectral interference on uranium was also studied. It was found that maximum leaching of uranium with the least concomitants was reached using 1M ammonium bicarbonate and 1M ammonium nitrate with percentage leaching efficiencies of 99.5% for both lixiviants. The optimized method was applied on three microgranite and two international certified samples BL-4a and DL-1a, where statistical evaluation showed that their average relative standard deviation was 0.61. - See more at:

In this paper, the compressive strength of geopolymeric binder prepared using the source materials such as fly ash, ground granulated blast furnace slag (GGBS) and ceramic waste powder without using any conventional cement has been investigated. The compressive strength was determined as per relevant Indian Standard. The different parameters considered in this study are the proportion of binder components such as ratio of Na2SiO3/NaOH solutions and alkaline liquid to binder ratio. The various combinations of fly ash, GGBS and ceramic waste powder considered are 80%, 10% &10%; 60%, 20% & 20% and 40%, 30% & 30% respectively. The ratio of binder to sand and Na2SiO3/NaOH solutions is taken as 1:2 & 1:3 and 2 & 2.5. The alkaline liquid to binder ratio is 0.45. The compressive strength of mortar cubes are determined at 7 and 28 days. It can be concluded that, as the percentage of the Ceramic waste powder increases, the compressive strength of the geopolymeric binder decreases when compared to conventional binder. - See more at:
We, human beings finding the solutions on energy crisis. It may be in terms of Alternate Energy sources, Increase in Efficiency or Saving of Fuel.

Investigation of Optimum Transparent Conductive Oxides (TCOs) for CdS:O/CdTe Thin Film Solar Cells (TFSCs) from Numerical Analysis. -
Transparent Conductive Oxides (TCOs) are an increasingly important component of solar cells, where they act as front electrode elements.The structural templates, diffusion barriers and their work function controls the open circuit voltage(Voc). In this paper, various transparent conductive oxide materials have been studied which are used as the front surface contacts of CdS:O/CdTe based thin film solar cells. Various electrical and optical parameters like work function, thickness, temperature etc., of some common transparent conductive oxides materials such as ZnO, FTO, SnO2etc., are studied. The main idea was to find an optimum conductive oxide layer for CdTe solar cell which shows the great potential in thin film area of solar cell. All the analysis was done by using the widely used simulator Analysis of Microelectronic and Photonic Structures (AMPS 1D). It was observed that both SnO2and ZnOshow similar performance under various conditions. Indium Tin Oxide (ITO) has shown the worst performance among them in all conditions.

A solar cell converts solar optical energy directly in to electrical energy. The major problem related to the solar cell is their lower efficiency. Typically when the surface of the solar panel increases, the efficiency of the solar panel decreases. Generally, a PV module has ideal conversion efficiency in the range of 15%. The remaining energy is converted into heat and this heat increases operating temperature of PV system which affects the electrical power production of PV modules and this can also cause the structural damage of PV modules, which leads to shorting its life span and lowering conversion efficiency. The cell efficiency can be increased by lowering the solar panel into liquid material, so that the temperature can reduce and the efficiency of the solar panel will increase. Another method of lowering the temperature of the panel can be achieved by passing the air continuously with the help of a blower on the rear side of the panel. So the temperature can be lowered and the air can be heated also, so that we can use it as solar air heater. Cooling is the transfer of energy from a space or from a air to space in order to achieve a lower temperature than that of natural surroundings. Temperature control of solar cells at high concentrations is a key issue. Short-term efficiency drop and long-term degradation should be avoided by effective cooling methods. In this communication, we will review to increase the efficiency of the solar panel with immersion system. - See more at:
Sprouting Suppression and Quality Attributes of Potato Tubers as Affected by Post-Harvest UV-C Treatment under Cold Storage
. Potato (solanumtuberosum, L.) is one of the most important vegetable crops in Egypt,it is considered as a source of national income since the potato crop is exported abroad because it has high quality specification.As a result of its cheap price and different prepared ways, potato is the most consuming crop by domestic consumer.So, the need to maintain the potato quality and preserve the crop without losses, providing good storage conditions after harvest is an important process for inhibiting sprouting, reduce the loss of weight and keeping the quality.The aim of this study is to investigate the effect of different doses of ultraviolet light (0, 1.42, 2.14 and 2.85 J/cm2) and different storage conditions (ambient air 45 ? 2oC with 50-60% RH, two cold dark storages, at 8oC?1with 75-82% RH and13oC?1 with 85-92% RH) on inhibition the sprouting of small tubers (60-90g) and big tubers (120-220g) after four months of storage.The analysis of variance(ANOVA) with three replicates (P < 0.05) based on Randomized Complete Block Design(RCBD) was conducted for the statistical analysis. It was concluded that increasing irradiation doses and decreasing storage temperature is good combination for sprouting suppression, reducing weight loss percentage, reducing the increment of soluble solids content, increasing firmness and remaining on the dry matter content almost constant. Only the tubers of non-irradiated treatment under ambient air storage showed percentage of damage. While,10 min irradiation treatment was very low to be effective in sprouting suppression or maintain other quality attributes at all storage temperatures. Exposure of 15 min UV-C is recommended as post-harvest treatment when small tubers are stored at 8oC. Storing tubers at 13oC after high irradiation doses showed very low sprouting weight for small and big tubers. - See more at
VIDEO-OBJECT STEGANOGRAPHY MECHANISM TO OVERCOME COMPRESSION LOSS IN BIOMETRIC BASED AUTHENTICATION.
When sensitive information is exchanged through wireless communication, it requires remote authentication. The Authentication is obtained by the biometric signal, which is difficult to forge copy and share. The method of steganography is employed in providing the authentication. The biometric signals is encrypted with a video-object and sent. The remote authentication is based on the semantic segmentation, chaotic encryption and data hiding. To authenticate user X remotely, X video-object is extracted then the biometric signal is encrypted by chaotic encryption. The encrypted biometric signal is inserted to the most significant wavelet coefficient of video-object by using QSWT (Qualified Significant Wavelet Tree). QSWT provide invisibility and resistant against lossy transition and compression. Now video-object along with biometric signal is extracted as stego-object which is compressed and sent to receiver. While decryption, IDWT (Inverse Discrete Wavelet Transform) is used to retrieve the biometric signal from video-object. One of the challenging problem in decrypting is the biometric signal is not clear for authentication. This loss occurs due to compression of stego-object. To overcome the above issue, Image Coder is used to detect the compression loss and Integrate Region Matching is used to reduce the compression loss. This method provides security in encryption and robustness against steganalytic attacks to various transmission losses and JPEG compression issues. This proposed method of biometric based authentication uses bandwidth in an efficient manner.see more
Permeability of scaffold is an important parameter which combines porosity, interconnectivity pore size and shape. It can influence on bone tissue engineering. The intrinsic permeability coefficient k of an open porous structure is ability to measure the fluid flow. Based on number of holes and standard pore diameter, 3D porous geometric models are created using commercial software SOLIDWORKS. In this study we found permeability co-efficient (k) of twelve different models with different shapes using Darcy?s law by satisfying all assumptions. For these models porosity may vary in the range of 20% to 50%.To obtain permeability co-efficient(k), pressure drops are found using CFD analysis for twelve porous models by considering boundary conditions from previous literatures and comparing permeability co-efficient(k) of porous models. - See more at:

In this paper, we proposed an approach to understand the mechanism of gas adsorption in a microporous solid. This approach is deduced from the concept of flow; the flow of the quantity of material which crosses a closed surface is proportional to the potential adsorbate-adsorbent interaction. For this first study, we used two couples; activated carbon AC35 with ethanol and acetone at the same temperature 30 ? C, in order to over complicate the issue for this first approach. Our study of the adsorption potential as a function of the pore radius allowed us to show that there are two types of interaction forces. The first type active, as in the case of adsorption in micropores and mesopores, and the second is active, as for the macropores and side surfaces of the grains. These findings justify the existence of two models: the Dubinin-Astakov (filling volume), and the Brunauer, Emmet and Teller (adsorption layer). Adsorption follows three steps, the micropore filling will occur the first followed by the filling of mesopores and the macropores and finally the surface adsorption corresponds to the side surface of the microporous solid grains. The order in which the filling pore has allowed us to establish the link between the time parameter and the pore radius - See moreat:

However, many biocides are causing serious environmental problems and may possess critical risks on treated agricultural crops. Materials and Methods: The study was designed to investigate the effects of biocides (azadirachta) treatment at different concentrations (0, 5, and 10) on few chemical constituents in plant leaves. Furthermore, the study also illustrated the extent to which an organic fertilizer could enhance deleterious impact of azadirachta indicia on plant growth. Lastly, in this study, lab experiments were performed on rats to examine influence of leaf on their liver function.The results were determined by one way Anova analysis of variance . Results: This study exhibits that low and high of Azadirachtin produced significant increase in total and soluble sugar content, compared with normal and fertilizer treated groups. Synchronized treatment of fertilizer with Azadirachtin in low and high dose showed significant increase in total and soluble content in contrast to normal and fertilizer groups. However, there is an exception of significant decrease in total sugar with high dose of Azadirachtin. Proline contents significantly increased in fertilizer treated group, while contents decrease significantly in other treated groups compared with normal and fertilizer. Chlorophyll A and chlorophyll B significantly increased in fertilizer treated groups. Low and high dose of Azadirachtin induced significant decrease in chlorophyll A and chlorophyll B content when compared with fertilizer treated group. High dose of Azadirachtin and low dose with fertilizer treated groups induced significant decrease in carotein content. Rats in all treated groups were observed with significant level of increase in AST activity with high dose of Azadirachtin group. LDH activity increased significantly in high dose of Azadirachtin . Total protein level, significant decrease was recorded in low dose of Azadirachtin group . Significant increase was observed in high dose of Azadirachtin alone, and in both high and low doses with fertilizer groups Conclusions: The study argued that biocides have their impacts on plant leaves. Hence, it is necessary to stay aware of chemical types applied on crops. Awareness should not limit to environmental contamination and toxicity, but their effects on crops should also be considered to obtain good quality of agricultural products for healthy consumption. The current investigation adequately proves that azadirachta indicia leaves are an effective heptaprotective agent at low dose. - See more at:

Green revolution has greatly increased the food crop production in India, but continuous cultivation of high yielding crop varieties have led to depletion of native micronutrient soil fertility and now most of the soils are showing sign of fatigue for sustaining higher crop production to meet the increasing food demand of the country. In the post-Green Revolution period, deficiencies of zinc (Zn) and boron (B) have constrained sustainable growth in productivity of several field crops. Among micronutrients, Zn deficiency was found widespread in Indian soils. Analysis of soils samples from different states of India indicated that on an average 44, 33, 15, 13, 8 and 6% of the samples were deficient in available Zn, B, iron (Fe), molybdenum (Mo), copper (Cu) and manganese (Mn), respectively. Extensive micronutrient deficiencies lead to decline in factor productivity even with balanced NPK fertilization. Although the crop response to micronutrients application varies with soil type, crops and genotype, agro-climatic conditions and severity of deficiency, an enormous response to micronutrient fertilization has been reported in a wide variety of crops including horticultural crops across the country. The results indicated that soil application of 5 to 10 kg Zn ha-1 before sowing is the most suitable method to manage Zn deficiency. The most effective method to ameliorate Fe deficiency is to apply 3-4 foliar sprays of 0.5 to 1.0% ferrous sulphate in standing crop at an interval of 10 days. For management of Mn deficiency 3-4 foliar applications of 0.5-1.0% manganese sulphate are economical than soil application of 40-50 kg Mn ha-1. Response of crops to B application (0.5-2.5 kg B ha-1) was observed on boron deficient soils. The soil application of boron is a better method of fertilization than foliar application or seed soaking. - See more at:

PEROXISOME PROLIFERATORS-ACTIVATED RECEPTOR- GAMMA GENETIC POLYMORPHISM AND NONALCOHOLIC STEATOHEPATITIS, CAN IT PREDICT DISEASE PROGRESSION! -
Background and study aims:- nonalcoholic fatty liver disease (NAFLD) is now the most common liver diseases. It progresses to liver cirrhosis with the incidence of hepatocellular carcinoma. Multiple hits theory in NAFLD progression indicates that genetic factors are important. Peroxisome proliferators-activated receptor-gamma (PPAR-gamma) has an essential role in the regulation of adipocyte-specific genes and lipid and glucose metabolism. We aimed at evaluating the role of PPAR-gamma single nucleotide polymorphisms (SNPs) in NAFLD and predicting its progression to nonalcoholic steatohepatitis (NASH). Material and methods:- Fifty obese patients with NAFLD preliminary diagnosed by liver ultra-sound were recruited. Full medical history, anthropometric measurements, biochemical studies, liver biopsy for the NAS score to identify NASH patients and the presence of fibrosis and assessment of SNPs of C681G, C689T and C34G of PPAR-gamma by Polymerase chain reaction-restriction fragmented length polymorphism (PCR-RFLP), were conducted for each patient. Thirty ages matched average weight healthy adult had been chosen as controls. Results:- The GG genotype of C681G was higher in cases (18%) than in control (10%) and also of C34G was higher in cases (12%) than in control (3.3%). The TT genotype of C689T was higher in cases (6%) than in control (0%). The GG genotype of C681G was higher in NASH group (19.4%) than in non NASH group (14.3%). Conclusion:- PPAR?gamma genetic polymorphism (C681G, C689T and C34G) was raised in patients with NAFLD and also of (C681G and C34G) was raised in cases with NASH but didn?t reach statistical significance.. - See more at:
Evaluation of Water Quality Index for the Groundwater in region around Buddha Nallah, Punjab, India. -
Buddha Nallah is a natural water stream. It passes through Ludhiana, which is industrial town of Punjab. Effluents from industries and domestic area joins stream and cause pollution. Pollution in stream leads to ground water pollution of nearby region. Study was conducted to evaluate water quality index (WQI) of ground water in region around Buddha Nallah in Punjab in districts Rupnagar and Ludhiana, India. Water quality index was determined by taking ground water samples from different sites during four different months over span of one year and analyzing the samples for various physico-chemical parameters. For evaluating WQI, eleven water quality features were studied; pH, total hardness, total dissolved solids, electric conductivity, calcium, magnesium, sodium, sulphate, phosphate, chloride and alkalinity. Results for WQI of samples studied varies from 49.83 to 224.96. Results clearly shows that in industrial town Ludhiana, ground water is polluted. WQI results were further used to predicting ground water quality of area studied. - See more at:
Introduction:-The previouslydescribed condition of localized juvenile periodontitis has been replaced by the term localized aggressive periodontitis. This condition presents a classic pattern and occurs in healthy children and adolescents without clinical evidence of systemic disease. It is characterized by the rapid and severe loss of alveolar bone around more than one permanent tooth, usually the first molars and incisors. Case report:- A 13-year-old female presented with clinical and radiographic evidence of severe attachment loss around several permanent teeth. She had no history of systemic disease, periodontal disease, or caries prior to the periodontal abscess that prompted her referral. Conclusion:- The early diagnosis and the management of these cases can help dentist to maintain the health and function of the permanent teeth and their surrounding structures. - See more at:
The prevalence of traumatic injuries to the primary dentition ranges from 11%?30%, but the incidence of dilacerated permanent teeth is very low and disproportionate to high prevalence of trauma. Hence, traumatic injuries to the primary dentition are unlikely to account for all cases of dilaceration and especially those of primary teeth themselves. An idiopathic developmental disturbance to deciduous dentition is proposed as another possible cause in cases that have no clear evidence of traumatic injury. The prime objective of the present article is to discuss cases of dilaceration in the deciduous anterior teeth and review the previous studies on dilacerations of the deciduous dentition. - See more at:
ANTIMICROBIAL ACTIVITY OF MEIZOTROPIS PELLITA (PATWA) AGAINST GRAMS POSITIVE AND GRAMS NEGATIVE BACTERIA. -
Meizotropis pellita (Fabaceae family), an endangered plant commonly known as Patwa was screened for potential antimicrobial activity against medically important bacterial strains, namely Bacillus subtilis, Staphylococcus aureus Streptococcus pyogenes, Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae. The antimicrobial activity was determined in alcoholic and aqueous extract using agar well diffusion method. The alcoholic extracts have shown antimicrobial activity while aqueous extract was inactive against all the tested bacterial strains. E.coli was the most resistant strain while Staphylococcus aureus and Streptococcus pyogenes were most sensitive bacterial strains.

Zinc oxide nanoparticles (ZnONPs) of average diameter of 45 ? 5.0 nm were prepared using chemical reduction method and characterized by UV-Visible spectroscopy, Scanning electron microscopy (SEM), Atomic force microscopy (AFM), X-Ray diffraction (XRD) and Fourier Transmission Infrared spectroscopy (FTIR). To test the ability of ZnONPs to ameliorate antihyperglycemic and the oxidative stress status resulted in experimental diabetic rats induced by alloxan, sixty male albino rats with weight 220 ? 25 grams and age of 9 months were used in experimental design. Ten of them were served as control group and fifty rats were injected with alloxan at the single intraperitoneal dose of 150 mg/kg. Then, subdivided into, diabetic, diabetic rats + ZnONPs I, received single daily dose of 2.5 mg/kg b.w ZnONPs in suspension. Diabetic rats + ZnONPs II, received a single daily dose of 5.0mg/kg b.w ZnONPs in suspension , diabetic rats + ZnONPs III, received a single daily dose of 10 mg/kg b.w ZnONPs in suspension, diabetic rats + insulin; received a single daily subcutaneous dose of insulin 2U/kg b.w. At the end of experimental time(60 days) the blood glucose, serum insulin,glycoslated HbA1c, lipid peroxidation marker, malondialdehyde (MDA), reduced glutathione (GSH) and serum activities of superoxide dismutase (SOD), glutathione peroxidase (GPx) and Catalase (Cat) were determined. Results showed a significant alteration in the activities of SOD, GPx, CAT, MDA Insulin, HbA1c and FBS in animals treated of ZnONPs, compared with diabetic or diabetic + insulin group and their control group. The profound control of ZnONPs over the anti-oxidant enzymes in diabetic rats to normal, by inhibition of lipid peroxidation and reactive oxygen species generation during hyperglycemia evidence their antioxidant effect during diabetes. The administration of ZnONPs at 10 mg/kg b.w exhibited an insistent control over the blood glucose level, lipids and serum biochemical profiles in diabetic rats near to the control group provokes their effective role in controlling and increasing the organ functions for better utilization of blood glucose. Histopathological studies revealed the non-toxic and protective effect of the ZnONPs over the vital organs and can be used to ameliorate the hyperglycemia and oxidative stress status. - See more at:
Airway management is core for an anesthesiologist. Airway difficulties during induction of general anesthesia are a concern for anesthesiologists. Hence a good clinical judgment is important for selecting the method for airway intervention. In patients of Mallampatti classification - IV or reduced mouth opening there are three methods for securing the airway. The most advanced and recommended method is awake nasal intubation using fibro-optic bronchoscope. The second option is retrograde intubation. The last method is blind nasal intubation. This method was regularly used to intubate patients of nil mouth opening before the fibro-optic bronchoscope was introduced. In experienced hands of an anesthesiologist, this is a very good method to secure the airway. It requires very little time compared to the first two methods and does not require expensive instruments. In today?s time blind nasal intubation is not performed regularly as the modern anesthesiologists are more dependent on instruments such as video- laryngoscope etc. However in centers where such expensive instruments are not available or in remote centers, blind nasal intubation can be the key for securing the airway for patients with difficult airway. Here we report a patient who is a case of squamous cell carcinoma of the cheek with reduced mouth opening posted for right wide excision of lip with forehead flap sos radical neck dissection managed with blind nasal intubation. - See more at:
Congenital tarsal coalition is a diagnosis that is often overlooked in young patients who first present with foot and ankle pain. Tarsal coalition is an abnormal fibrous, cartilaginous or osseous fusion of two or more tarsal bones . The prevailing etiologic theory for congenital coalitions is failure of complete segmentation of mesenchyme with the absence of normal joint formation. Approximately 50%?80% of cases of tarsal coalition are bilateral  and more than 90% of coalitions are located between the calcaneus and the navicular or between the talus and calcaneus . Calcaneonavicular and talocalcaneal coalitions have been reported to occur in approximately equal frequency . However, recent investigations suggest that calcaneonavicular coaltions occur 3 times more frequently . - See more at:
Background: The chronic liver disease is one of the most deadly diseases in Egypt and around the world; perfect diagnosis methods are urgently needed. The proper assessment of liver fibrosis offers acute information for both perfect diagnosis and accurate therapeutic decision-making. Although digital image analysis (DIA) is a promising method for quantitative assessment of liver fibrosis, it has not been fully evaluated in practice yet. The present study was designed to explore the possibilities of using open access image analysis software (ImageJ) for accurate quantitative assessment of liver fibrosis. Methods: This study investigated the use of digital images analysis by software ImageJ of liver sections stained by sirius red (SR). Reproducibility of this technique was tested in comparison with the a semi-quantitative score of liver fibrosis as well as other markers of fibrosis including physiological markers of liver functions such as alanine transaminase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT). In addition, it was tested compared to serum marker collagen IV (Col IV) and hepatic hydroxyproline. Results: From physiological point of view; hepatic hydroxyproline, serum Col IV and ALT showed higher accuracy, sensitivity and specificity than other physiological markers with area under curve (AUC) of 0.935, 0.955 and 0.902 respectively. On the other hand, DIA of SR by ImageJ software had shown the best accuracy with AUC of 1.0. In conclusions: our novel data prove that the use of ImageJ with semiautomatic color segmentation is a reliable and practical way of measuring collagen proportionate area. - See moreat
Background:-Evidence based practice (EBP) is a way to transfer evidence obtained from research into everyday provision of health care services. A dentist should not only know about the sources to obtain evidence, but also be able to critically assess the mountain of research studies available. This study was aimed to determine EBP knowledge, attitudes, confidence in critical appraisal skills and methods for accessing evidence among oral health professionals in Mangalore, India. Material and method:-We used a standardized and validated 36 item EBP KACE (Knowledge, Attitudes, Confidence and Evidence) questionnaire which consisted of 4 domains, Knowledge of Critical Appraisal, Attitudes about Evidence-Based Practice, Confidence in Critical Appraisal Skills and Accessing Evidence. Statistical analysis was performed using student?s t test, binary logistic regression and bivariate correlation tests. Results:-A total of 133 males and 231 females took part in the study (n=364). Participants were divided into interns, postgraduate students and specialists. Mean knowledge of postgraduates (2.45; SD 1.2) was highest. Attitudes levels were similar for postgraduates (4.4; SD 2.5) and undergraduates (4.7; SD 2.6). Postgraduate students were more aware of newer methods of accessing evidence (4.1; SD 2.0) (p < 0.01) compared to others. Conclusions:-Postgraduates had greater knowledge of EBP and better ideas of ways to access evidence. The undergraduates showed a positive attitude and interest towards evidence based practice. Hence, making evidence based practice a formalized part of dental curriculum would enable young dentists to make optimal treatment decisions essential in the interest of the patient as well as the community. - See moreat:
Association of TGF-β1 Polymorphism with Type 2 Diabetes Mellitus and Diabetic Nephropathy in Saudi Patients.
Diabetic nephropathy is the common process that is leading to ESRD. Several studies showed that TGF-β is a major anti-inflammatory cytokine involved in extracellular matrix deposition and thickening of basement membrane of glomeruli. This study is aimed to evaluating the association of TGF-β1 gene polymorphisms (869T/C) and (509C/T) with complicated and uncomplicated type 2 diabetes mellitus. Methods: 250 Saudi male classified into; 100 healthy males as control, 80 uncomplicated type 2 diabetes mellitus male patients and 70 type 2 diabetes mellitus male patients with nephropathy. Blood and urine samples were collected from all groups for measurement of plasma glucose, urea, cholesterol, triglyceride, HDL-C, urea, creatinine and TGF-β1. In addition a genotyping of TGF-β1 was done. Results: our results showed a statistical difference in TGF-β1 levels in all groups, also a positive correlation between hyperglycemia and HbA1c with TGF-β1 level was detected. According genotype, only 869T/C genotypes are involved in susceptibility to T2DM and diabetic nephropathy. Both TC and CC genotype are higher in T2DM patients compared with control (P<0.05), while only CC is higher in diabetic nephropathic patients compared with uncomplicated T2DM (P<0.05). Conclusion: an increase TGF-β level may be involved in processes of T2DM development and its nephropathic complication. In addition, the TC and CC genotypes of TGF-β1 869T/C are more susceptible to T2DM, while only CC genotype to diabetic nephropathy.see more

Current status of tribal population as reported 2011 census is 8.6% of the nation total population, whereas the tribal population of Maharashtra is 8.6 million. Tribal population of Buldhana District is 115,000(Revenue division TRTI,Pune)Buldana District falls under Amravati division. It was of profound interest to assess nutritional status of the adolescent tribal. However in journal data are scanty on the anthropometry and nutritional status of various tribal populations of India. For Anthropometry body weight in kg, height in centimeters was measured. Further data of height and weight was subjected to calculations values express with means standard deviation and compared with NCHS standard deriving difference results presented in tabularly and graphically. Data was further subjected to BMI values expressed with means and standard deviation. BMI categories were observed by classifying data of BMI and values expressed with percentage. Data on anthropometry revealed that both male and females adolescent were falling short of height as less weight compared to the NCHS standard. Classification of subjects based BMI revealed that irrespective of sex and age groups, a major percentage was falling in normal weight category, followed by under weight category. It has been recently suggested that there is urgent need to evaluate the nutritional status of various tribes in India. (Bose and Chakraborti, 2005, Bose et al 2006). - See more at:

CHANGES OF S. CARDIAC MARKERS AFTER ACUTE ATTACK OF MI BACKGROUND: Blood testing for biomarkers of myocardial injury plays an important role for the evaluation, diagnosis, and triage of patients with chest pain. The criteria for the diagnosis of myocardial infarction have been redefined recently, as reported in a document of the European Society of Cardiology (ESC) and the American College of Cardiology (ACC), and require at least 2 of the 3 following characteristics: (1) typical symptoms; (2) characteristic rise-and-fall pattern of a cardiac markers or (3) a typical electrocardiogram (ECG) pattern involving the development of Q waves. Currently serum troponins, can now detect extremely small amounts of myonecrosis (<1.0 g), which, in the setting of an ACS, may be associated with increased risk of complications. MATERIALS AND METHODS: Patients are selected from those attending department of medicine, G.G. Hospital, M.P. Shah Medical College, Jamnagar. Blood samples of patients were taken to measure the serum LDH, Troponin I, CRP, CK-MB levels by ELISA (enzyme linked immunosorbent assay) and their levels are compared with clinical condition, ECG changes and prognosis of the patients. RESULT: Out of 100 patients studied 70 patients were in age group 40-70yrs, 74 patients were having history of hyper tension and 55 patients were having complaint of chest pain were diagnosed as having acute MI. CONCLUSION: Troponins are ideal markers which enable early detection of patients with acute coronary syndrome whereas inflammation markers are helpful in diagnosis and assessing the severity of inflammation - See more at:

ASSOCIATION OF ADIPONECTIN GENE POLYMORPHISM rs266729 WITH ADIPONECTIN LEVELS IN TYPE 2 DIABETIC PATIENTS WITH AND WITHOUT CVD. IN AL-NAJAF GOVERNORATE, IRAQ.
Background:- Cardiovascular diseases are a group of disorders of the heart and blood vessels. Adiponectin is an adipocyte-secreted protein with insulin-sensitizing and anti-atherogenic properties. Many studies demonstrated that polymorphisms within the adiponectin gene could be associated in T2DM with and without CVD. Methods:- A case-control study was conducted to find the association between SNP rs266729 in T2DM with and without CVD in Al-Najaf Governorate, Iraq. The study included 203 T2DM patients with CVD randomly selected based on World Health Organization (WHO) guideline and 133 T2DM patients without CVD as controls group. DNA was extracted from blood and genotyped by PCR-RFLP by using (Hha1) enzyme. Multinomial logistic regression was applied to compare the proportions of genotypes and alleles. The odds ratio for risk of developing CVD in T2DM was calculated with and without adjustment for age, sex, and BMI. Results:- The frequency of G allele of rs266729 (C/G) polymorphism was significantly lower (p=0.0001) in T2DM with CVD (27.3%) compared to that without CVD (33.08%). The homozygous genotype (GG) significantly (0R=7.570, CI 95%(1.597-32.530), P= 0.011) increased the risk of T2DM with CVD seven folds with respect to those of the wild type (CC) after adjustment age, sex, and BMI, furthermore the heterozygous (CG) genotype significantly [0R=2.818,CI 95%(1.00-12.596), P= 0.050] raised the risk of T2DM with CVD by two folds. Homozygous and heterozygous genotypes of rs266729 polymorphism exhibited significant association with decreased adiponectin levels (P= 0.08). Conclusion:- Adiponectin gene polymorphism rs266729 is involved in the pathogenesis of T2DM with CVD. In addition this SNP may play a role in the development of cardiovascular diseases and metabolic syndrome by affecting HDL and adiponectin levels. - See more at:

Should local health decision makers? use programme budgeting and marginal analysis (PBMA) as a basis for priority setting?
Decision makers in health care have to constantly face the problem of allocating resources judiciously. In the face of competing demands for healthcare, decision makers need to prioritise which interventions to fund. Countries around the world are trying to make these allocations decisions based on explicit framework. At a national or country level, decisions are taken under certain rules and regulations. But many times, local decision makers need to prioritise among different interventions. In these cases, the article looks at Programme Budgeting and Marginal Analysis (PBMA) as an explicit priority setting framework for the local level. The author looks into the reasons behind the need for an explicit priority setting framework, the principles and steps of PBMA and how it is helpful at the local level. - See more at
To clarify if changing the diet helps to prevent development of diabetes, the current study aimed to provide the immunomodulatory effect of cinnamon (CN) in improving the histological picture in the pancreatic tissue in diabetic rats. This improving picture were visualized in the well-organized islets containing increased number of ? cells, ? cells appeared with normal chromatin distribution and normal cellular population. CN administration to alloxan diabetic rats reduced serum glucose, triglyceride, total cholesterol, LDL cholesterol levels and boosting the immune system by increasing HDLcholesterol levels and insulin expression. In conclusion, the regular intake of CN in the daily diet may show many immunological benefits. - See more at:
Children growth and development is continuous process. The developmental progression of self esteem through once life span has beautifully explained in psychosocial theory by Eric Erikson ?A study to evaluate the effectiveness of creative art on self esteem among physically disabled children in special school at Mysore? 60 samples were selected experimental and control group, using non probability purposive sampling technique. The sample of the study comprised children studying special school (Deaf and Dum) with the age group of 10-14 years, those who are fulfilling the inclusion criteria. Data collection was done by using self esteem inventory scale to assess the self esteem among special school children. In the analysis Experimental group? paired ?t? test computed between mean pretest and post test level of self esteem was significant at 0.05 level. Calculated ?t? value 23.74 greater than ?t? Table valuet29=2.05. Creative art can provide the children easier way to express the self esteem themselves as they are more naturally, artistic and creative, as a parents respect the children?s activities and encourage in positive ways especially physically challenged children. - See more at:
Simultaneous Quantification of T-Cell Receptor Excision Circles (TRECs) and K-Deleting Recombination Excision Circles (KRECs) by Real-time PCR. -
Background: The clinical experience gathered throughout the years endorses primary immunodeficiency diseases (PIDs) awareness and guides research into newborn screening and future therapeutic strategies.Combined T-cell receptor excision circle levels (TRECs) and kappa-deleting recombination excision circles (KRECs) assay paves the way to new potential applications in this field. Objectives: We aimed to establish a technique for quantification of TRECs and KRECs in Egyptian individuals in our laboratory and to set a lower threshold of normal for TRECs and KRECs in pediatric population for different age groups as a start for its implementation in newborn screening protocols for PIDs. Methods: 50 apparently healthy children (25 males and 25 females) with age ranging from 1 day to 16 years were analyzed..Combined quantification of TRECs and KRECs in the genomic DNA of peripheral blood mononuclear cells was performed using real-time quantitative PCR. Results: Individuals in the study were divided in to 5 different age groups Data regarding lower threshold of normal for TRECs and KRECs copies per ml of blood among the study group was obtained. A highly significant negative correlation between TRECs and KRECs, both calculated per 106 PBMCs and per ml of blood and age was observed. On the contrary, there was no statistically significant differences in the studied parameters between males and females when evaluated regardless of age (p value=0.697). Conclusion: It appeared that it is technically feasible to introduce the TRECs/KRECs quantitation by real time PCR into routine laboratory practice to be used in the near future both for new born screening for PIDs - See more at:
EVALUATION OF DIFFERENT MODALITIES OF SURGICAL TREATMENT IN EXTRACAPSULAR FRACTURE OF PROXIMAL FEMUR.
INTRODUCTION:The incidence of fracture around hip has increased a lot with gradual increase in general life expectancy of the population. The fracture around hip accounts for about one third of all hospitalized patients. Among the different type of fractures around hip extracapsular fracture of proximal end femur are most common. The incidence is more than the fracture femoral neck proper. In elderly, 90% of extracapsular fracture results from trivial injury while in young adult it results from high energy trauma like motor vehicle accident. The incidence of extracapsular fracture in elderly is more than fracture in young adult because of several factors like osteoporosis, decreased muscle power, poor vision. These fractures are associated with a substantial morbidity and mortality and account for a large amount of expenditure in the treatment. Now days mode of treatment is changing from conservative to surgical, so it need to study different treatment modality forextracapsular fracture ofproximal femur. AIM AND OBJECTIVE:To assess and evaluate different surgicalmodality of management in extracapsular fracture of proximal femur. MATERIAL AND METHOD:This was prospective analytic study, conducted at the Department of Orthopaedics and Traumatology, D.M.C.H., Laheriasarai, Darbhanga in year 2007 to 2010. Total 32 Cases were selected by inclusion and exclusion criteria. Out of 32 cases, 12 cases were treated with PFN and 20 with DHS. All the operations were done under image intensifier control. Follow up of the patients were done up to 48th postoperative weeks for the assessment of functional and anatomical result. OBSERVATION AND RESULT:Present series is of 32 cases, of it 43.75% were male and 56.25% were female, Average age was 50-70 years. Most common mode of injury was trivial injury/minor slip comprising 46.87% patients in which 31.25% female and 15.62% male. Second commonest mode of injury was Road Traffic accident comprising 25%, in which 15.62% were male and 9.37% were female. The # was classified by EVAN’S classification, 59.37% cases were of stable fracture, 28.12 of unstable type and 12.50% were subtrochanteric type fracture. # were reduced under image intensifier and fixed with D.H.S or P.F.N. by 3rd postoperative weeks, in PFN group 91.66% of cases were partial weight bearing with crutches, But in DHS group by 6th postoperative weeks 75% of cases partial weight bearing with help of crutches, full weight bearing in P.F.N group was 12-18 wk and in D.H.S group it was 18-24 wk. 8% in P.F.N group and 15% in D.H.S group had superficial infection while 10% in D.H.S group had deep infection, no deep infection in P.F.N group. CONCLUSION:In PFN group patients, blood loss and soft tissue dissection was less as compared to DHS group patients.Within first 3 months PFN allowed a faster postoperative restoration of walking ability as compared to DHS. It was found that there was no major difference between PFN and DHS treatment group long term follow-up in clinical and radiological features. - See more at:
