Dairy Farmers' Awareness of Vector-Borne Zoonotic Diseases: A Pilot Study.

Background: A quantitative cross-sectional pilot study was conducted to determine dairy farmers' general awareness of vector-borne zoonotic diseases, i.e., dengue fever and chikungunya fever caused by alphavirus and mosquito-borne flavivirus, as well as the relationship between these and other demographic variables such as gender and education level. Materials and Methods: A total of 42 farmers from the Wayanad district of Kerala were surveyed using a well-structured KAP (Knowledge, Attitude and Practice) questionnaire. Results: The study revealed that farmers have inadequate knowledge and attitudes regarding chikungunya, as well as inadequate practices regarding dengue fever. Similarly, there is a significant correlation between gender and chikungunya fever awareness. Conclusion: The study emphasizes the need to increase awareness of these diseases among dairy farmers and emphasizes the significance of conducting additional research on the area and population.

Role of Alanine Racemase Mutations in Mycobacterium tuberculosis d-Cycloserine Resistance.

A screening of more than 1,500 drug-resistant strains of Mycobacterium tuberculosis revealed evolutionary patterns characteristic of positive selection for three alanine racemase (Alr) mutations. We investigated these mutations using molecular modeling, in vitro MIC testing, as well as direct measurements of enzymatic activity, which demonstrated that these mutations likely confer resistance to d-cycloserine.

Efficacy of soy protein isolate as a fat replacer on physico-chemical and sensory characteristics of low-fat paneer.

The nutritional and textural properties of low fat paneer using soy protein isolate (SPI) as fat replacer was investigated. The physico-chemical and sensory characteristics of 4 types of paneer made of low-fat milk (3% milk fat (MF) and 10% solids-not-fat (SNF)) and SPI of 0 (T1), 0.1 (T2), 0.2 (T3) and 0.3% SPI (T4) were compared with high fat paneer (TC) made of high fat milk (6% MF and 9% SNF). CaCl2 (0.2%, w/v) was used as coagulant at 75 ± 1°C. Increased level of SPI in paneer increased yield, protein, ash, moisture content and decreased fat, moisture protein ratio, lactose and calorie contents. Titratable acidity and pH varied in narrow range. Instrumental firmness was higher (p ≤ 0.05) in T1-T4 than in TC. The gumminess, chewiness and firmness showed the same trend. Resilience and cohesiveness values showed no significant difference among the samples. Hunter colour L values showed a decreasing, and a and b values increasing trend with increasing levels of SPI. Sensory appearance and colour scores were lower (p ≤ 0.05) for T1-T4 than TC. More than 0.2% SPI imparted beany flavour to paneer.

Definitive or conservative surgery for perforated gastric ulcer?--An unresolved problem.

BACKGROUND: Gastric ulcer perforation has not been the focus of many studies. In addition there is a need to analyze the results of gastric perforation separately and not along with duodenal perforations, to identify the factors influencing the outcome and to develop strategies for its management. MATERIALS AND METHODS: Retrospective analysis of 54 patients presenting with gastric perforation. RESULTS: Mean age of the patients was 44.5 years with male preponderance. Morbidity following Closure of the perforation, acid reduction surgery and resection was not significantly different. Overall mortality was 16.6% with highest mortality 24.1% following simple closure. Mortality following simple closure and definitive surgery was not significantly different. Univariate analysis revealed preoperative shock, associated medical illness and surgical delay to be significant factors for mortality whereas on multivariate analysis, preoperative shock was the only independent predictor of mortality. Mortality increased with increasing Boey score but the association between the type of surgery and probability of survival was not statistically significant. CONCLUSION: Boey risk score is useful in predicting the outcome of surgical treatment for gastric perforation. Definitive surgery is not associated with greater morbidity or mortality compared to simple closure.

A validated stability indicating ion-pair RP-LC method for zoledronic acid.

The present paper describes the development of a stability indicating high performance liquid chromatographic (HPLC) assay method for zoledronic acid in the presence of its impurities and degradation products generated from forced decomposition studies. The drug substance was subjected to stress conditions of hydrolysis, oxidation, photolysis and thermal degradation. The degradation of zoledronic acid was observed under oxidative stress at higher temperature. The drug was found to be stable in other stress conditions attempted. Successful separation of the drug from the degradation products formed under stress conditions was achieved on a C18 column using a mixture of phosphate buffer that contains 7 mM tetra butyl ammonium hydrogen sulphate, an ion-pairing agent and methanol (95:5) as mobile phase. The developed HPLC method was validated with respect to response function, precision, accuracy, specificity and robustness. The developed HPLC method to determine the related substances and assay determination of zoledronic acid can be used to evaluate the quality of regular production samples. It can be also used to test the stability samples of zoledronic acid.
