Summary: Testosterone levels peak during the breeding season in white-tailed deer population in Alabama, with older bucks having higher testosterone levels than younger bucks during this period. Individual testosterone levels as a yearling are not directly correlated with lifetime maximum testosterone levels, but mean testosterone levels are positively associated with lifetime testosterone variation. This study contributes to understanding hormonal patterns in cervids and potential intraspecific variation in lifetime reproductive strategies.

Summary: Hair can be used as a useful matrix to examine the hormonal status of animals. In this study, seasonal changes in cortisol and testosterone levels were evaluated in four feline species with different breeding strategies. Both hormones showed annual dynamic fluctuations, coinciding with the reproductive seasonality of the species. Sexual differences in testosterone levels were only found during the mating season, with higher levels in males. Cortisol levels increased during the mating period, and in caracal, increased cortisol was associated with animal transfer to smaller cages.

Summary: Serum levels of 11-oxygenated androgens are higher in women with PCOS than in controls. However, these hormones show a poor performance in recognizing women with hyperandrogenism, as currently defined. The relationships of these androgens with insulin sensitivity strongly differ from that of FT, suggesting a different role of classic and 11-oxygenated androgens in the pathophysiology of PCOS.

Summary: This study aimed to develop non-invasive methods for assessing the reproductive and well-being status of the pygmy hippopotamus. By analyzing fecal samples, the researchers successfully measured hormone levels and identified seasonal variations in gonadal activity in male pygmy hippos. These findings have important implications for the conservation and management of this endangered species.

Summary: This study validates a non-invasive technique to quantify glucocorticoid levels in the amphisbaenian reptile Trogonophis wiegmanni. The technique involves quantifying corticosterone metabolites from fresh fecal samples and was able to detect an increase in the fecal glucocorticoid metabolite levels after external corticosterone supplementation. The study also found a high interindividual variation in baseline fecal glucocorticoid metabolite levels in a field population of this reptile, suggesting the potential for using this technique to investigate environmental causes of variation.

Summary: Androgens are crucial for male sexual development, masculinisation, and fertility. HSD17B3 deficiency can lead to disorders of sexual development (DSD). Recent studies suggest differences in testosterone production between mice and humans.

Summary: Colorectal cancer is a common and serious disease globally. Fecal examination is a simple and non-invasive method for clinical examination, and it is widely used for large-scale population screening. In recent years, with the advancements in molecular biology, researchers have focused on discovering new fecal biomarkers for early screening and diagnosis of colorectal cancer.

Summary: CRC is one of the top five lethal malignant tumors globally and in China, and early diagnosis and treatment are crucial for improving survival rates. The gut microbiome could serve as a potential non-invasive screening tool for CRC, with a few specific bacteria genus identified as effective biomarkers for clinical use. Analysis of gut microbiome composition in CRC patients versus healthy controls showed significant differences, with 13 bacteria identified as biomarkers with high sensitivity and specificity for discriminating CRC patients. This method has the potential to be a non-invasive approach for early diagnosis of CRC.

Summary: The role of androgens, age, and rank position in the regulation of intrasexual competition and aggression in primate females was studied. The study found that levels of estradiol were positively associated with female-to-female aggression, while testosterone levels were negatively associated with female-to-male aggression and positively associated with dominance rank. Age was not found to affect aggressive behaviors. Male-to-female aggression was predicted by sexual behaviors, but not by female hormonal levels.

Summary: This study indicates that serum androgen levels start declining early in adult life, independently from changes in BMI and other lifestyle factors. The decline in androgen levels most likely arises from a primary decrease in testicular function.

Summary: The role of estrogens and progesterone in endometrial cancer is well-known, but there is limited information about the role of androgens. Five different androgens are produced in women: DHEAS, DHEA, A(4), T, and DHT. T and DHT are the most potent hormones, with DHT mainly produced from T in peripheral tissues including the endometrium. While androgens are generally considered to have anti-proliferative effects and their receptor expression is associated with a good prognosis in endometrial cancer, it is still unclear in which specific conditions androgens have carcinogenic or protective effects in endometrial cancer.

Summary: The use of non-invasive hair snare surveys has become more popular in wildlife research and management, but it often fails to gather information on elusive carnivores like bobcats. This study aimed to develop a novel, passive bobcat hair snare that can be used regardless of terrain or vegetation features for population estimation. The newly developed hair snare was deployed in West Virginia for two sampling seasons, resulting in a higher detection rate compared to previous studies. Further development of this platform should increase its usefulness in capture-recapture studies.

Summary: This study found that cadmium exposure during pregnancy may lead to lower testosterone levels in pregnant women, while estrogen levels remain unchanged. This effect may be stronger in pregnancies carrying female fetuses. Further research is needed to understand how alterations in gestational testosterone activity may impact pregnancy and child health.

Summary: This study aimed to investigate the effects of hormonal therapy on spermatogenesis in transgender women (TW), and found that adequate hormonal therapy can lead to complete suppression of spermatogenesis in most cases, but in some cases, spermatogenesis may still occur. It is crucial to discuss sperm preservation before starting hormone therapy.

Summary: The study found that repeatability of locomotor activity in Q-flies increased with the carbohydrate content of the diet in different nutritional environments, suggesting that nutrient availability limits the expression of genetic activity. The results highlight the importance of considering the complexities of nutrient content and composition in studies of the evolutionary potential of traits and individual variation in behavior.

Summary: This study investigated the role of estrogen receptors (ERs) in vitellogenesis (Vtgs) regulation in pompano fish. The findings suggest that E2 may regulate the expression of different subtypes of vtg through ERs, displaying a compensatory expression effect on the regulation of ers and vtgs. This provides a theoretical basis for further research on reproductive endocrinology in pompano fish.

Summary: Endocrine changes during bird reproduction, particularly the relationship between prolactin and incubation behavior, were investigated. The study monitored the physiological status and incubation behavior of Silkie hens over 1-2 years. The results showed that most mature hens exhibited incubation behavior multiple times, and there was a noticeable increase in nest occupancy 7-10 days before incubation onset. Protein analysis revealed that secreted prolactin during the reproductive cycle contains various isoforms, suggesting post-translational modifications like glycosylation and phosphorylation.

Summary: The COVID-19 pandemic had a significant impact on academics, particularly on those with minoritized identities or who were early career, caregivers, or had intersecting identities. The pandemic altered the impact factors of academia, including scholarly products, and affected the way individuals could respond. It is predicted that the pandemic will have long-term impacts on the population dynamics, composition, and landscape of the academic ecosystem. The number of journal submissions decreased, especially among women authors, and the pandemic heavily impacted women authors from Asia and the Middle East.
