<p>This study focused on the observed impact of switching from a corn / soybean agricultural rotation to the planting of warm season perennial grasses for use in biomass agriculture, as well as the subsequent effects on resident mammal populations. We trapped two parcels of land planted in warm season perennial grasses between September 2011 and October 2013 in order to obtain a census of the mammal populations residing upon the property and to determine the impact (if any) of the change in agriculture. During the first year of the study, a seemingly inhospitable (urban) agricultural area revealed a diverse population of inhabitants. The second year of trapping resulted in the capture of 2 new species (total of 7 species captured) and the noticeable absence of 1 species; a distinct shift in mammal populations had been observed. There was an inverse relationship between the population increase of <em>Peromyscus maniculatus</em> during 2012 and the decline in the population of <em>Peromyscus leucopus. </em>When a Chi-square test was run (<em>P</em>&lt;0.05), the hypothesis of competitive exclusion appeared to be supported. In the third year, population numbers of <em>Peromyscus</em> <em>maniculatus</em> had also plummeted. We observed that warm season perennial grass monoculture had an adverse impact on resident mammal species.</p>

Background: Medical students of Bangladesh have to encounter English as learning media. But teachers often do not use English exclusively in their lectures thinking that students may not understand English clearly.Objective: To assess the impact of exclusive use of English language in physiology lectures on student’s learning.Method: This comparative study was conducted in the Department of Physiology, Abdul Malek Ukil Medical College, Noakhali, Bangladesh during January – November, 2013. One hundred and sixteen first year MBBS students of two sessions of a government medical college were enrolled for the study by purposive sampling. Exclusive English was used in physiology lectures of 1st term course for the students of 2012-2013 session (group EE) and mixed Bengali and English was used to teach the students of 2011-2012 session (group BE). First term examination results were compared by Student’s ‘t’ test and Chi-square test as applicable.Result: The students of EE obtained significantly higher mean marks both in written (p<0.001) and oral (p<0.001) examinations than those of group BE. However there was no significant difference between groups in pass rate (p>0.05)).Conclusion: The students who attended the lectures with exclusive English obtained better marks in individual component of assessment than the students who attended the lectures with mixed Bengali and English. However, English language use in teaching showed no effect on the pass rate.Bangladesh Soc Physiol. 2017, June; 12(1): 28-32

Purpose: To assess ocular pathologies admitted to Italian Emergency Eye Departments (EEDs) during the COVID-19 pandemic national lockdown in 2020 in comparison with the same period in 2019. Methods: Electronic records of all patients presenting at EEDs of two tertiary-care Eye Centers during the COVID-19 national lockdown in Italy (March 10–May 3, 2020) were compared with the equivalent period in 2019. Main outcomes were patient age, gender, and diagnoses. Statistical analysis included unpaired Student t-tests, Poisson regression, and chi-square test. Results: Overall EED visits significantly decreased by 54.1% during the 2020 lockdown compared to 2019 (851 vs 1854, p < 0.001). During lockdown, patients showed comparable mean age (52.8 years in 2020 vs 53.3 years in 2019, p = 0.52) and significant male gender bias (61.1% in 2020 vs 55.8% in 2019, p < 0.0001). The most frequent pathologies were eye inflammations, trauma-related incidents, and spontaneous acute vitreous detachment. Patients with inflammation, headache/hemicrania, and spontaneous subconjunctival hemorrhages were significantly less, whereas those with trauma-related diagnoses were significantly higher during the lockdown as compared with 2019 ( p < 0.05). The proportion of non-urgent visits decreased from 17% in 2019 to 8% in 2020 ( p < 0.001). Conclusions: During the 2020 lockdown, there was a significant reduction of accesses to EED, especially for non-urgent pathologies. Potentially visual function threatening conditions, such as trauma-related pathologies, retinal detachment or ruptures, and wet AMD, showed lower number of cases but higher or stable proportion relative to the total caseload, suggesting a correct and efficient access to ophthalmic health care during the pandemic period.

The current work is aimed at generating information on giant crickets and the impact of commonly used pesticides on the natural population of these crickets. Data was collected based on interviews and complemented with field observations. Out of 319 respondents surveyed, 290 were aware of the use of the giant cricket as a food source, and 161 were active consumers. Regarding the availability of the giant cricket, respondents reported that the crickets’ populations were diminishing because of farming practices. About 219 persons reported that commonly used herbicides harm giant crickets at different stages. This could be attributed to the scarcity of this species, as mentioned by 233 respondents. The results showed that 130 respondents were engaged in gathering giant crickets for consumption. This insect gathering is related to soil tilling. Chi-square test showed a significant dependence relationship between herbicides use and cricket scarcity. Although less than a majority (129) of respondents are making regular use of persistent pesticides (herbicides), it has been observed that intensive use of pesticides could become a popular practice in smallholder farming categories. This paper thus suggests the need for training and surveillance concerning the trade of pesticides in the region and proposes further investigations into pesticides residues or traces in collected giant crickets consumed in the study site and in all areas with similar conditions.

<p>English listening is one of the five basic skills such as listening, speaking, reading, writing and translation that a Chinese postgraduate should acquire, and it is also the most significant one. In this study, 194 first-year postgraduate students at Shanghai University of Engineering Science were invited to report their strategies use and listening anxiety in the questionnaire with the 5-Likert Indirect Foreign Language Listening Strategies Scale and the 5-Likert Foreign Language Listening Anxiety Scale. The SPSS13.0 was used to analyze the descriptive statistics, reliability analysis, correlation analysis, Chi-square test and One-way ANOVA, which indicated a medium listening anxiety and a medium level of strategies use. Metacognitive strategies were more frequently used than social and affective strategies, the correlation between listening proficiency and listening anxiety was significantly negative, correlation between listening proficiency and indirect listening strategies was significantly positive, and that between indirect listening strategies and listening anxiety was significantly negative. Indirect listening strategies were useful to allay listening anxiety and would be incorporated into our normal classroom teaching.</p>

Objective: this quantitative descriptive study aimed to evaluate the presence of deleterious oral habits and associated factors in children attending the Amadeu Barros Leal day care in Fortaleza, CE, Brazil. Material and Methods: the sample consisted of 75 children (51% of girls) aged 0 to 5 years. Data were collected through the application of a structured questionnaire to the parents or guardians and analyzed statistically with Fisher’s exact or Chi-square test, considering a 95% confidence interval. The results were expressed as absolute frequency and percentage. Results: 89% of the children participating in the study were breastfed, and 43.5% of them were breastfed at least until the first year of age. As much as 19% of the children slept with their mouths open and 39% used a pacifier, 56.7% of which used it constantly during the day and at night. About 91% of children used a feeding bottle, and most of bottles (79%) did not have an orthodontic nipple. In addition, 60% of children aged 24-36 months had the deleterious habit of grinding their teeth. Conclusion: in the present study, we investigated children from 0 to 5 years old and observed that this age group is predisposed to deleterious oral habits. In this way, more studies that trace a safe epidemiological profile aiming to reduce these harmful habits are extremely necessary.
