This study in western Hudson Bay, Canada, examined trace elements in the hair of adult male polar bears and found significant differences in concentration patterns along the hair length, suggesting laser ablation ICP-MS is a promising tool for monitoring these variations over time.

This article discusses the discovery of the first known menstruating rodent, the spiny mouse, and proposes that a significant increase in progesterone during the luteal phase is a unique feature of menstruating species, but reports no new experimental results.

In this study, adding disinfected feathers to the diet of captive Arctic foxes increased gut bacterial species diversity without changing overall abundance, potentially influencing immune response and physiological performance.

This study observed that hair loss in captive rhesus macaques varies with season, sex, and housing conditions, and is significantly correlated with HPA axis activity as indicated by faecal cortisol metabolites.

This A.S.P.E.N. document offers guidance for managing parenteral nutrition shortages, emphasizing alternative routes and careful allocation to prevent deficiencies.

This study suggests that the prevalence of red beards in individuals with dark hair may be explained by Thayer’s Theorem of countershading.

This study found that selecting Angus cattle for early puberty reduced their prolactin levels, which may indicate a response to changing day length.

This study found that cows with alopecia, ill-thrift, and infertility exhibited significant decreases in serum copper, zinc, calcium, inorganic phosphorus, magnesium, and hematological measures, indicating moderate microcytic, hypochromic anemia.

This study suggests that the prevalence of alopecia areata in the US remains similar to high estimates from the 1970s, with significant implications for quality of life.

In this study, researchers observed that telogen hair was more prevalent than anagen hair in both male and female agoutis over a one-year period in Teresina-PI, regardless of dry or rainy seasons, with no significant differences in dermal follicular volume between the sexes.

This study analyzed gene expression changes during the autumn coat color change in mountain hares and found conserved gene regulation with snowshoe hares, highlighting its role in seasonal camouflage adaptation.

This study observed that adult male raccoon dogs undergo seasonal moults, with winter fur maturing by the end of November after significant hair growth in spring and autumn.

This study found that in captive mouflon rams, reproductive and physical maturation, marked by changes in hormone levels and physical attributes, progresses gradually across their life span, with sexual maturity tied closely to physical maturity.

This study found that due to variability in measurements, hair pluckability is not a reliable indicator of adult nutritional status, although it may hold potential in certain emergency situations if improved for consistency.

This study reports that the incidence of alopecia areata is 0.26 per 1000 person-years in the UK, with higher rates among Asian ethnic groups, socially deprived populations, and urban residents.

This study found that prenatal antiandrogen treatment in female spotted hyenas significantly altered the LH response to GnRH, indicating partial masculinization of their anterior pituitary gland without affecting ovulatory function.

This collection of articles explores advancements in reproductive technologies for domestic dogs and cats, highlighting improvements like finasteride treatment for BPH in dogs and a rapid freezing method for cat sperm that enhance fertility preservation and genetic resource banking.

In this animal study, serum biotin levels and clinical symptoms in gilts suggested that serum biotin could serve as a sensitive indicator of biotin deficiency, and a system to evaluate biotin status was proposed.

This study observed that skin pigmentation significantly attenuates bioluminescent signals in C57Bl/6 mice, complicating quantitative optical imaging and requiring consideration in experimental design.

This review highlights the potential of platelet-rich plasma as a therapeutic tool in animals, noting its mixed efficacy and promising applications in areas like reproduction, but reports no new clinical results.

Melatonin improved sheep reproduction, being more beneficial and cost-effective in males.

The researchers reported that alopecia is common in Japanese macaques, particularly adult females, and varies seasonally and between different populations, with a new scoring system proposed for monitoring.

This study used a zebrafish model and advanced mass spectrometry to identify 11 metabolites of epristeride, revealing significant effects on purine metabolism and aromatic amino acid biosynthesis, which may aid in developing anti-doping detection methods.

This study found that adrenal hormones appear to inhibit winter fur growth onset in mink and may affect the duration of inactivity between fur growth periods.

This study found that individuals with alopecia areata experience variations in cortisol and insulin levels and adaptive mechanism pressures, which may serve as potential therapeutic targets.

This review discusses the occurrence and impact of background histopathologic changes in nonhuman primate research, emphasizing the importance of understanding these factors to enhance study validity and interpretation.

The KDM1 gene helps Venus flytraps close by managing potassium ions.

This index reviews the clinical examination of farm animals and reports no new research findings.
