China is recognized as a selenium-deficient country, and nutritional selenium intake has always been a concern. To clarify the current inhabitants’ selenium nutrition status and the characteristics of dietary consumption in low-selenium areas, samples of human hair and grains were collected, and food frequency questionnaires were administered in Binxian County, Shaanxi Province, a typical low-selenium area in the Loess Plateau. The subject number of the study is 85, and the age range is from 11 to 81 years, with an average of 60. The results showed that the average hair selenium content of the residents was 231.7 μg/kg, and 62.4% of the participants had levels higher than the selenium deficiency threshold (200 μg/kg). There was a significant positive correlation between the hair selenium content and the food consumption score after adjusting for rice outsourcing. Three different dietary patterns were noted according to hierarchical cluster analysis. This study provides a tool for assessing the selenium nutrition of inhabitants in low-selenium areas and has considerable significance for improving the dietary pattern of residents.

The average selenium levels measured in the analyzed European bison individuals (N = 22) were as follows: 0.137±0.041SD μg/g dry weight (DW), 0.175±0.032 and 1.004±0.239 μg/g wet weight (WW) in hair, liver and kidneys, respectively. Broken down by sex, the average hair selenium concentration was 0.140±0.046 and 0.134±0.037 μg/g DW in males and females, respectively. No significant differences in hair selenium content were found in relation to sex. As far as age is concerned, hair selenium content was 0.142±0.042 in calves; in the group of bison over 2 years of age, however, lower levels of selenium (0.126±0.040 μg/g DW) were recorded. There were no significant differences between the age groups in terms of selenium content. Based on our research and current literature data, we could presume selenium deficiency in the studied animals.

Abstract Background COVID-19 has impacted populations around the world, with the fatality rate varying dramatically across countries. Selenium, as one of the important micronutrients implicated in viral infections, was suggested to play roles. Methods An ecological study was performed to assess the association between the COVID-19 related fatality and the selenium content both from crops and topsoil, in China. Results Totally, 14,045 COVID-19 cases were reported from 147 cities during 8 December 2019–13 December 2020 were included. Based on selenium content in crops, the case fatality rates (CFRs) gradually increased from 1.17% in non-selenium-deficient areas, to 1.28% in moderate-selenium-deficient areas, and further to 3.16% in severe-selenium-deficient areas (P = 0.002). Based on selenium content in topsoil, the CFRs gradually increased from 0.76% in non-selenium-deficient areas, to 1.70% in moderate-selenium-deficient areas, and further to 1.85% in severe-selenium-deficient areas (P < 0.001). The zero-inflated negative binomial regression model showed a significantly higher fatality risk in cities with severe-selenium-deficient selenium content in crops than non-selenium-deficient cities, with incidence rate ratio (IRR) of 3.88 (95% CIs: 1.21–12.52), which was further confirmed by regression fitting the association between CFR of COVID-19 and selenium content in topsoil, with the IRR of 2.38 (95% CIs: 1.14–4.98) for moderate-selenium-deficient cities and 3.06 (1.49–6.27) for severe-selenium-deficient cities. Conclusions Regional selenium deficiency might be related to an increased CFR of COVID-19. Future studies are needed to explore the associations between selenium status and disease outcome at individual-level.

Selenium is a non-metallic chemical element of great important to human health. Low selenium levels in humans are associated with several pathological conditions and are a common finding in HIV infected individuals. We conducted a review of the literature to assess if selenium deficiency or selenium supplementation could play a role in modifying the clinical course of HIV disease. Several studies investigated the role of selenium in disease progression, morbidity and mortality in HIV infected individuals. Larger studies were conducted in countries with poor economic resources and limited access to HAART. According to the majority of published studies low selenium levels appear to have an association with mortality, and selenium supplementation appears to play a beneficial role on survival or on slowing disease progression among HIV infected individuals. The role of selenium supplementation on preventing hospital admission among HIV outpatients was also noticed. The literature suggests an association between selenium deficiency and development of HIV associated cardiomyopathy and furthermore, selenium supplementation appears to improve the cardiac function in HIV infected individuals with cardiomyopathy. However, there is conflicting evidence regarding the role selenium in modifying HIV viral load and immune status in HIV infection.

<p>The purpose of the study was to investigate factors perceived to contribute to the decline of students’ performance in the Botswana’s General Certificate of Secondary Education (BGCSE) agriculture results. Ninety-one agriculture examiners were randomly sampled out of 100 teachers who were invited to mark the 2012 end of year examination scripts. A questionnaire was mailed by post and partly hand delivered to gather quantitative data. The SPSS software was used for statistical analysis. The results showed that majority (57%) of the agriculture teacher examiners were male, 66% were in the age range of 31-35 years old. A large proportion (66%) of them had taught for a period of 6 to 15 years. The study revealed positive perceptions of teachers on three constructs influencing the decline on the students’ performance in agriculture. The study revealed that under the construct,<em> Students’ behaviors, social and economic related factors, students attitudes towards the subject </em>yielded high mean (x̅)‘= 4.45<em>,</em> STD (σ) ’ = .81;<em> on Factors related to curriculum issues, </em>the study sho<em>we</em>d<em> </em><em>“</em><em>interpretation of examination items</em><em>”</em><em> </em>had high mean<em> </em>(x̅) ‘= 4.39<em>,</em> STD (σ) = .75 and under the construct on <em>Factors related to resources and infrastructure </em>the mean (x̅) was = 4.79<em>,</em> STD (σ) = <em>.53 </em>was high on the <em>student teacher ratio. </em>The study concluded that the three constructs studied had influence towards students’ performance in agriculture. However, based on interpretational correlations the results did not find any strong relationship among the demographic variables studied.</p>

Three cases of nutritional myodegeneration caused by selenium deficiency in adult horses are described. Difficulty in eating and drinking was a common clinical sign in all horses. Blood biochemistry revealed a marked elevation of muscle enzymes and low glutathione peroxidase activity or low selenium concentration in whole blood in all cases. The treatment with sodium selenite and vitamin E was instituted in all horses. Two of them were euthanized because of continuing muscle injuries, one patient was cured. The post-mortem examination of euthanized horses revealed pale muscles that were distributed with bilateral symmetry on hind and thoracic limbs, diaphragm, tongue, masticatory and intercostal muscles and the myocardium. Histopathology revealed the areas of degeneration and necrosis. Large groups of regenerating fibres and pronounced lymphoplasmocytic reaction among the groups of intact fibres were also present. The clinical outcome of the disease is probably influenced by timely diagnosis and treatment.

1. Two duplicate groups of rainbow trout (Sulmo gairdneri; mean weight 27 g) were given diets of differing selenium content (deficient 0, 025 mg Se/kg; supplemented 1.022 mg Se/kg) for 30 weeks.2. There were no significant differences between treatments in weight gain but packed cell volume, liver vitamin E and liver and plasma Se concentrations were all significantly lower in the Se-deficient trout.3. Ataxia occurred in about 10% of the Se-deficient trout and histopathologies were evident in nerve cord (damage to axon sheath) and liver (loss of integrity in endoplasmic reticulum and mitochondria with appearance of increased vesiculation).4. Glutathione peroxidase (EC 1.11.1.9) activity was significantly reduced in liver and plasma of Se-deficient fish but there was no indication, from differential assay, of any non-Se-dependent glutathione peroxidase activity. Glutathione transferase (EC 2.5. I.18) activity was significantly increased in Se-deficient trout.

Elementary school teachers are one of the sources of student’s misconceptions, so their understanding needs to be identified. However, the process of identifying the understanding of the concept of science is still small and only on certain materia. This study was aimed to investigate elementary school teacher's understanding of sound concepts. This study uses a qualitative approach with descriptive type. The research data are sourced from elementary school teachers' answers to questions about the concept of high and low sounds, in the form of a teacher's justification for the statement of questions presented along with the discussion. The population was all grade 4 elementary school teachers in Surakarta (120 teacher), the sample of 30 teachers from public and private elementary schools, the status accreditation A and B, with a purposive random sampling technique. The sample taken consisted of teachers in the age range of 30 to 60 years, 11 male teachers and 19 female teachers, and 50% were certified educators. Data collection techniques are carried out by providing diagnostic tests of misconceptions on the subject of the concept of high and low sounds. Data analysis technique refers to the category of concept understanding formulated by Tuysuz (2009), which is understanding, misconception, not understanding, and guessing. The results showed that in understanding the concept of high and low sounds 1.11% of teachers understood the concept well, 71.11% of teachers did not understand the concept, 26.67% of teachers experienced misconceptions, and 1.11% of teachers guessed.

Abstract Populations of greater sage-grouse (Centrocercus urophasianus) have declined throughout the species' range. We evaluated metal concentrations in livers sampled from greater sage-grouse collected from hunters in Eureka County, Nevada, during autumn of 2008 and 2010. We make local comparisons of metal concentrations between two populations of greater sage-grouse in Eureka County, as well as regional comparisons with previously reported values for greater sage-grouse collected in Wyoming and Montana. With one exception, tissue concentrations of lead, arsenic, and mercury were below method detection limits. Mean concentrations of iron, molybdenum, and zinc differed between the two Nevada populations, and magnesium, cadmium, molybdenum, and selenium differed between greater sage-grouse in eastern Nevada, and values reported for Wyoming and Montana. In contrast, we found no evidence for local variation in magnesium, copper, cadmium, or selenium, or for regional variation in iron, zinc, or copper. Of particular interest were low selenium concentrations in our study system relative to Wyoming and Montana. Some individuals in our study returned liver selenium values considered consistent with selenium deficiency in domestic poultry. This research adds to the small body of literature on background contaminant levels in greater sage-grouse, and provides evidence for geographic variation in metal concentrations at local and regional scales.
