RÉSUMÉ
Rice is the most staple food crop for the human population worldwide. Both biotic and abiotic diseases are known to cause losses to the Rice crop. Mostly, grain yield losses are reported due to blast disease caused by Magnaporthe oryzae across all crop growing areas of the world. Leaf blast samples were collected from various rice-growing areas in Warangal and samples were tested on different growth media and found that OMA+Rice leaf extract was the most suitable for promoting radial growth, conidial size, and sporulation of the pathogenic isolate. Among the eight isolates studied, the Maheshwaram isolate (M-2) exhibited the highest radial growth, conidial size, and good sporulation. This suggests that this particular isolate might be more aggressive or virulent than the others and could pose a greater threat to rice crops in the region.This could lead to more effective strategies for managing blast disease and minimizing yield losses in rice crops in the specific region.

Purpose: Dry eye is a common condition affecting people worldwide. It causes ocular discomfort by reducing the quality of vision and impacts daily activities. To overcome such ocular discomfort, artificial tears are used but it is difficult to use artificial tears every time to protect eyes from dryness. There is a need to explore other treatment options, which can be used during work hours. The aim was to study the effect of salivary stimulation on tear film functions among dry eye subjects. Methods: Thirty?three subjects were enrolled in this prospective experimental study. Tear film function tests such as tear break up time (TBUT), tear meniscus height (TMH), and Schirmer’s I and II tests were conducted. For dry eye subjects, salivation was induced by giving a tamarind candy (a soft slightly sour tamarind pulp mixed with sugar) for 5 min. Tear film function tests were carried out within a few seconds (2 to 3 s) after finishing the candy and then after 30 and 60 min of the induction of salivation. The pre? and post?tear film function measurements were recorded and analyzed. Results: TBUT, TMH, and Schirmer’s II tests showed statistically significant (P < 0.05) increase immediately and after 30 min of stimulation of salivation for all tests in both eyes. However, the difference was insignificant after 60 min of stimulation of salivation. Schirmer’s I showed statistically significant changes in the left eye, but not in the right eye immediately after stimulation of salivation (P = 0.025). Conclusion: The quantity as well as the quality of tear film improved after the stimulation of salivation among dry eye subjects.

Background: Dependence on using biomass fuels for cooking and heating leads to Indoor Air Pollution (IAP) which can lead to adverse health outcomes. Aim of this study was to observe the housing and kitchen conditions in households of tribal areas, assess the knowledge of women regarding the IAP and perceived health effects due to it.Methods: Cross-sectional community- based study conducted in 100 women above the age of 18 years in a tribal village. A semi-structured questionnaire was used and spot observations were made. Chi-Square was used to calculate the association between type of stove, housing conditions and health effects of IAP. Logistic regression was used to identify determinants of the health effects of IAP.Results: The mean age of women was 29 years; all houses had a separate kitchen; 34% used mud stove with wood. Easy availability and economic reasons were cited for using wood. 47% of women thought IAP present in their homes and the most common source was cooking. Symptoms like asthma, sweating, burns/rash, and headache had a significantly higher association in women using mud stove (P<0.05) than LPG stove. A strong association was found between cooking hours and health effects due to IAP (P< 0.004).Conclusions: IAP due to cooking and unfavorable housing conditions are associated with health problems in women. Knowledge regarding IAP is poor. Reasons for reliance on using mud stove needs to be addressed.
