The present study was conducted to evaluate the physicochemical and anti-oxidative properties of cow, buffalo and goat urine samples in two different successive seasons (summer and winter). For the physicochemical study, pH, electrical conductivity (EC), total dissolved solids (TDS) was measured and for the antioxidant properties, FRAP, DPPH and ABTS level was evaluated by standard methods. The data set were executed through the independent ‘t’ test by using IBM SPSS software version 22.0. The results showed that the EC level in all the (except cow) was significantly pandlt;0.5 lower in the winter season than in the summer season. TDS level in buffalo was significantly pandlt;0.5 lower in the winter season than the summer season but significantly higher in the winter season of the goat urine sample. In the case of antioxidant markers, FRAP and DPPH levels were significantly pandlt;0.5 higher in the summer season in all the animals, but there were no significant changes in the case of ABTS in all the animal’s urine samples. From these results, it is concluded that in the study area, the stress in the summer season as heat stress prevails in dairy cows, buffalo and goats. From the overall findings, it may be concluded that urine could be a good biomarker to evaluate the status of livestock health.

In this paper, a total 46 algae belonging to 34 genera and 3 classes (Chlorophyceae 54%, Bacillariophyceae 28%, Cyanophyceae 18%) have been reported from Rajarani Lake, Dhankuta, Nepal. Among these, 13 algae were reported as new to the country. Genera Ankistrodesmus, Closterium, and Desmodesmus had maximum number of species whereas 25 genera were represented by single species. Seasonal variation of algae showed that there was changing number and type of algae with physicochemical parameters in different seasons. Cyanophycean algae Microcystis flos-aque was dominant and observed in all sites in every collection of winter, summer and rainy seasons, and followed by bacillariophyceaean algae i.e., Aulacoseira granulata var. angustissima. The maximum number of algae was found in summer (59%) followed by winter (50%) and rainy (31%) seasons. There were 6 common algae found in all season’s viz. Ankistrodesmus falcatus, Aulacoseira granulata var. angustissima, Flagilaria tenera, Microcystis flos-aquae, Navicula radiosa and Oedogonium sp. Algae viz., Anabaena affinis, Cyclotella meneghiana, Pinnularia divergens, Pinnularia interrupta, Tetrastrum heteracanthum, and Ulothrix subtilissima were found only in winter season whereas, Aulacoseirsa granulata var. muzzanensis, Bolbochaete sp, Closterium striolatum, Cylindrospermum muscicola, Desmodesmus abundans, Desmodesmous quadricauda var.bicaudatus, Eunotia bilunaris, Gomphonema lacusrankaloides and Gomphonema pseudoaugur were observed only in summer.

Objective: To determine distribution of dermatologic disease among major league baseball (MLB) players and compare the distribution to that seen in the general population.Design: Cross Sectional SurveySetting: Data was collected via anonymous, online, randomized survey in January 2017.Participants: Head athletic trainers for 25 MLB teamsMain Outcome Measures: The distribution of dermatologic disease encountered by MLB athletic trainers for players versus non-player personnel.Results: The 3 most commonly encountered dermatologic conditions for MLB trainers among baseball players were blisters, contact dermatitis, and nail problems including onychomycosis. In contrast, the 3 most common dermatoses seen among the non-player personnel control group were rash, tinea, and concerning skin lesion which more closely resembled the distribution of skin diseases among the general population.Conclusions: MLB players experienced a different mix with a greater proportion of mechanical, infectious, and contact related skin conditions likely due to the baseball-related activities that impact on these athletes’ skin on a day-to-day basis. The prevalence of the dermatologic disorders noted in the study reinforces the importance of focused dermatologic education for trainers to enhance player care.

Background: Vitamin D deficiency is a common problem in many countries throughout the world. This study aimed at understanding the status of vitamin D deficiency in relation to age, gender, geography and season among relatively bigger numbers of population residing in central and western regions of Nepal.Methods: This retrospective cross-sectional study was carried out by reviewing the records of vitamin D tests in two centers of Nepal- namely united reference laboratories at Pokhara and Chitwan Medical College at Chitwan. A total of 3320 individuals who were tested for clinical suspicion of vitamin D deficiency over a period of one year were included in the study. Results: Mean vitamin D level was 18.7 ng/mL. Majority of subjects tested for vitamin D were females (71.36 %) with female to male ratio of 2.49:1. Hypovitaminosis D (? 30 ng/mL) was found in 84.5% subjects and was moderate to severely deficit (<10 ng/mL) in 25.9% of subjects. Status of hypovitaminosis D was found to be less in ?50 years (79.9%) than the younger subjects (89.9% in ?18 years and 87.0% in 19-49 years age group). Vitamin D deficiency was found lower in hills districts (80.8% vs 89.7% in the plains), which was found to be more pronounced during winter through summer seasons as compared to fall season.Conclusions: Population residing in plain areas and summer, spring and winter season are found to have increased problem of Hypovitaminosis D. It is also found to be common among younger children and female of reproductive age group. We have also found out the increased problem of hypovitaminosis D among population residing in the plain areas than in the hills especially in the summer, spring and winter season.Keywords: Geographic variation; hypovitaminosis D; Nepal

BACKGROUND Wikipedia is one of the most popular websites and may be a go-to source of health and dermatology education for the general population. Prior research indicates poor skin of color (SOC) photo representation in printed dermatology textbooks and online medical websites, but there has been no such assessment performed to determine whether this discrepancy also exists for Wikipedia. OBJECTIVE The aim of this study was to investigate the number and quality of SOC photos included in Wikipedia’s skin disease pages and to explore the possible ramifications of these findings. METHODS Photos of skin diseases from Wikipedia’s “List of Skin Conditions” were assigned by three independent raters as SOC or non-SOC according to the Fitzpatrick system, and were given a quality rating (1-3) based on sharpness, size/resolution, and lighting/exposure. RESULTS We identified 421 skin disease Wikipedia pages and 949 images that met our inclusion criteria. Within these pages, 20.7% of images of skin diseases (196 of 949 images) were SOC and 79.3% (753 of 949 images) were non-SOC (<i>P</i>&lt;.001). There was no difference in the average quality for SOC (2.05) and non-SOC (2.03) images (<i>P</i>=.81). However, the photo quality criteria utilized (sharpness, size/resolution, and lighting/exposure) did not capture all aspects of photo quality. Another limitation of this analysis is that the Fitzpatrick skin typing system is prone to subjectivity and was not originally intended to be utilized as a non-self SOC metric. CONCLUSIONS There is SOC underrepresentation in the gross number of SOC images for dermatologic conditions on Wikipedia. Wikipedia pages should be updated to include more SOC photos to mend this divide to ameliorate access to accurate dermatology information for the general public and improve health equity within dermatology.

This study presents the results of a seasonal municipal solid waste composition campaign, that took place over the period of September 2017 to June 2018 in the capital city of Kazakhstan, Astana. Four sampling campaigns were conducted in order to identify the seasonal variation of municipal solid waste composition, recyclables and energy potential materials, such as combustible fraction, useful for the evaluation of waste-to-energy potential. The combustible fraction was analysed for thermal fuel properties, such as proximate and elemental analyses and gross calorific value. The results over the four different seasons showed that the average recyclable fraction of municipal solid waste on a wet basis of 33.3 wt.% and combustibles fraction was 8.3 wt.%. The largest fraction was the organics (47.2 wt.%), followed by plastic (15.4 wt.%) and paper (12.5 wt.%). Small seasonal variations were observed for organics, paper, plastic and glass fractions. The highest values were found in summer for the organic waste, in spring for paper and plastic and autumn for glass. The recyclables fraction showed an absolute seasonal variation of 5.7% with a peak in the winter season (35.4%) and the combustibles fraction showed a seasonal variation between 8.3 wt.% to 9.4 wt.%. Finally, the average calorific value of the combustible fraction was estimated to be 21.6 MJ kg-1 on a dry basis.
