Monitoring the feeding and parental care behavior of a pair of free-living owls (Tyto furcata) in the nest during the reproductive period in Rio de Janeiro, Brazil

The American Barn Owl (Tyto furcata) lives in urban, periurban and wild environments and feeds mainly on small rodents, meaning it has great importance in the biological control of pests. The aim of this work was to describe the reproductive, parental and eating habits of a pair of American barn owls naturally living outside a residence in the urban area of the municipality of Campos dos Goytacazes, Rio de Janeiro state, Brazil. A wood box was installed on an outside wall of the home, monitored by a video camera. A spreadsheet was created to keep track of the observations recorded. The female laid four eggs, and after an incubation period of 30-32 days all the eggs hatched, but only two chicks survived after cannibalism among the chicks. Initially, the male provided the food to the chicks and the female remained in the nest caring for the brood. After approximately a month, the female also began to leave the nest and return with prey, which was offered to the chicks, with the male also continuing this behavior. The chicks left the nest in September, 2017. The data obtained show the existence of cooperation and division of tasks between male and female owls during the reproductive period.

Post-weaning Social Isolation in Male and Female Prairie Voles: Impacts on Central and Peripheral Immune System

The socially monogamous prairie vole (Microtus ochrogaster) offers a unique opportunity to examine the impacts of adolescent social isolation on the brain, immune system, and behavior. In the current study, male and female prairie voles were randomly assigned to be housed alone or with a same-sex cagemate after weaning (i.e., on postnatal day 21–22) for a 6-week period. Thereafter, subjects were tested for anxiety-like and depressive-like behaviors using the elevated plus maze (EPM) and Forced Swim Test (FST), respectively. Blood was collected to measure peripheral cytokine levels, and brain tissue was processed for microglial density in various brain regions, including the Nucleus Accumbens (NAcc), Medial Amygdala (MeA), Central Amygdala (CeA), Bed Nucleus of the Stria Terminalis (BNST), and Paraventricular Nucleus of the Hypothalamus (PVN). Sex differences were found in EPM and FST behaviors, where male voles had significantly lower total arm entries in the EPM as well as lower latency to immobility in the FST compared to females. A sex by treatment effect was found in peripheral IL-1β levels, where isolated males had a lower level of IL-1β compared to cohoused females. Post-weaning social isolation also altered microglial density in a brain region-specific manner. Isolated voles had higher microglial density in the NAcc, MeA, and CeA, but lower microglial density in the dorsal BNST. Cohoused male voles also had higher microglial density in the PVN compared to cohoused females. Taken together, these data suggest that post-weaning social housing environments can alter peripheral and central immune systems in prairie voles, highlighting a potential role for the immune system in shaping isolation-induced alterations to the brain and behavior.

Proses Penalaran Kuantitatif Menggunakan Kerangka Referensi Siswa Ditinjau Dari Gender

The results of previous studies showed that the ratio of the differences in the level of quantitative reasoning abilities between male students and female students was quite significant. While the frame of reference refers to a series of mental actions through which individuals can regulate the processes and products of quantitative reasoning. Therefore, there are two main objectives of this study, namely to show whether or not there are differences in quantitative reasoning products using a frame of reference between male and female students, then to describe the process of quantitative reasoning using a frame of reference between male and female students. Using Sequential Mixed Methods, this study examined 58 students of class VIII junior high school. The research was conducted in two phases, namely the quantitative phase which included statistical data analysis using the Mann Withney Test to determine whether there were differences in the product of quantitative reasoning using the frame of reference for male and female students. Then the qualitative phase includes a description of the quantitative reasoning process using a frame of reference for male and female students. The results of the study stated that there were differences in the product of quantitative reasoning between male and female students. This is indicated by the results of statistical tests in the quantitative phase, while the qualitative phase found that male students were able to analyze the formulas that were determined according to the results of their own interpretation of the information provided implicitly or explicitly in the questions compared to female students. Keywords: Quantitative Reasoning, Frame of Reference, Gender Abstrak Hasil penelitian sebelumnya menunjukan rasio perbedaan tingkat kemampuan penalaran kuantitatif antara siswa laki-laki dan siswa perempuan yang cukup signifikan.

Comparison of Treatment Response before and after Antiobsessivae Therapy among Psychiatric Patients with Obsessive Compulsive Disorder

Introduction: Obsessive compulsive disorder is a common, chronic and disabling disorder marked by obsessions and/or compulsions. This study tries to find the demographic profiles, severity and response of antiobsessive drugs in young and adult patients with obsessive compulsive disorder. Aims: To study the socio-demographic profile, severity and treatment response to commonly used antiobsessive medications in male and female, and young and adults. Methods: This is a hospital based experimental study done in patients attending to psychiatry out-patient department over one year from February 2020 to January 2021. Diagnosis of obsessive compulsive disorder was made based on International Classification of Disease- 10 criteria for research. Yale-Brown obsessive compulsive scale check list (adult and children) was applied in those patients and recorded accordingly on baseline (week 0) and patients were treated with specific serotonin reuptake inhibitors or tricyclic antidepressants in therapeutic doses for 6 weeks. On follow up at week 6, they were again reassessed and the scores were recorded and analyzed. Results: Among the total study subject (N-52), 26(50 %) were male and 26(50 %) were females. Patients in age bracket 20-29 is the most common age group representing 18(34.6 %). Mean age of patients is 30.36±11.93 years (28.65±9.80 in male and 32.04±13.73 in female). Severe form of obsessive compulsive disorder was the most common type that represent 33(63.5%) followed by moderate 16(30.8%) and extreme 3(5.7%). There is a difference of treatment response of antiobsessive therapy in male and female with statistical significance (p= 0.039). Conclusion: This study shows that obsessive compulsive disorder is most commonly found in 20-29 age group and the severe type is the most common. There is a significant difference in treatment response of antiobsessive therapy in male and female.

Examining sex differences in the completeness of Peruvian CRVS data and adult mortality estimates

The production, compilation, and publication of death registration records is complex and usually involves many institutions. Assessing available data and the evolution of the completeness of the data compiled based on demographic techniques and other available data sources is of great importance for countries and for having timely and disaggregated mortality estimates. In this paper, we assess whether it is reasonable, based on the available data, to assume that there is a sex difference in the completeness of male and female death records in Peru in the last 30 years. In addition, we assess how the gap may have evolved with time by applying two-census death distribution methods on health-related registries and analyzing the information from the Demographic and Health Surveys and civil registries. Our findings suggest that there is no significant sex difference in the completeness of male and female health-related registries and, consequently, the sex gap currently observed in adult mortality estimates might be overestimated.

Gene Polymorphisms Among Plasmodium vivax Geographical Isolates and the Potential as New Biomarkers for Gametocyte Detection

The unique biological features of Plasmodium vivax not only make it difficult to control but also to eliminate. For the transmission of the malaria parasite from infected human to the vector, gametocytes play a major role. The transmission potential of a malarial infection is inferred based on microscopic detection of gametocytes and molecular screening of genes in the female gametocytes. Microscopy-based detection methods could grossly underestimate the reservoirs of infection as gametocytes may occur as submicroscopic or as micro- or macro-gametocytes. The identification of genes that are highly expressed and polymorphic in male and female gametocytes is critical for monitoring changes not only in their relative proportions but also the composition of gametocyte clones contributing to transmission over time. Recent transcriptomic study revealed two distinct clusters of highly correlated genes expressed in the P. vivax gametocytes, indicating that the male and female terminal gametocytogeneses are independently regulated. However, the detective power of these genes is unclear. In this study, we compared genetic variations of 15 and 11 genes expressed, respectively, in the female and male gametocytes among P. vivax isolates from Southeast Asia, Africa, and South America. Further, we constructed phylogenetic trees to determine the resolution power and clustering patterns of gametocyte clones. As expected, Pvs25 (PVP01_0616100) and Pvs16 (PVP01_0305600) expressed in the female gametocytes were highly conserved in all geographical isolates. In contrast, genes including 6-cysteine protein Pvs230 (PVP01_0415800) and upregulated in late gametocytes ULG8 (PVP01_1452800) expressed in the female gametocytes, as well as two CPW-WPC family proteins (PVP01_1215900 and PVP01_1320100) expressed in the male gametocytes indicated considerably high nucleotide and haplotype diversity among isolates. Parasite samples expressed in male and female gametocyte genes were observed in separate phylogenetic clusters and likely represented distinct gametocyte clones. Compared to Pvs25, Pvs230 (PVP01_0415800) and a CPW-WPC family protein (PVP01_0904300) showed higher expression in a subset of Ethiopian P. vivax samples. Thus, Pvs230, ULG8, and CPW-WPC family proteins including PVP01_0904300, PVP01_1215900, and PVP01_1320100 could potentially be used as novel biomarkers for detecting both sexes of P. vivax gametocytes in low-density infections and estimating transmission reservoirs.
