In this study, researchers assessed cortisol levels in wolves by comparing hair and fecal samples and found a significant correlation, indicating that hair cortisol accurately reflects systemic levels, but season and body region affect results.

This study observed that the reproductive phenology of Ficus species in Northern Thailand varied seasonally, with female trees producing the most figs during the rainy season, while male trees' fig production peaked earlier.

This study found that serum prolactin and dehydroepiandrosterone levels did not determine the onset of mink hair growth cycles, though their metabolites may influence other aspects of hair growth.

This study found that among Australians aged 15 and older, the lifetime prevalence of alopecia areata ranged from 1.2% to 2.3%, and the point prevalence ranged from 0.9% to 1.4%, emphasizing the need for better awareness and education about treatment options.

This study found that both oral and topical formulations of VISPOTM, a saw palmetto oil, significantly reduced hair fall and increased hair density in subjects with androgenetic alopecia, with no serious adverse effects observed.

This study suggests that red deer stags provide a novel model for investigating hormonal regulation of hair growth due to the different cell growth rates in hair follicles during breeding and nonbreeding seasons.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

This study found that women with female pattern androgenic alopecia have significantly higher levels of certain androgens and androgen sulfates compared to normal premenopausal women, suggesting markers for diagnosis and treatment efficacy.

In this study, Dodatek A operationalizes the Functional Androgen Axis framework by defining three system-level indices and an efficiency metric to describe androgen function, incorporating key methodological improvements and acknowledging significant limitations for future empirical validation.

This review discusses recent advancements in omics and gene editing technologies for studying neuropeptides and receptors in fish, but reports no new experimental findings; the authors highlight the need for further research in this area.

This study in Aswan governorate reported that emaciated cattle showed decreased blood cell counts and serum minerals, as well as elevated liver enzymes, possibly associated with parasitic infections.

This study in Mosul City, Iraq, examined mange infestation in rabbits, finding that 43.1% of 130 rabbits were infested, with Sarcoptes scabiei var. cuniculi being most prevalent, and noted no significant gender differences but age-related variations in infestation rates.

The study concluded that a dietary vitamin A level of 10,000 IU/kg optimally supports growth performance, fur quality, and antioxidant function in growing Rex rabbits.

This study found that a single topical dose of fluralaner effectively eliminated Lynxacarus radovskyi mites from naturally infested domestic cats within 42 days, with treated cats remaining mite-free until day 98, unlike the untreated control group which continued to test positive.

This study describes the successful management of Andean bear alopecia syndrome in three female bears using oclacitinib, leading to rapid pruritus resolution and fur regrowth without adverse effects.

In this study, researchers developed and validated a method to quantify pyrrolizidine alkaloids in honey and flour, increasing alkaloid recovery rates through successive extractions, achieving up to 86% recovery for honey and 76% for flour.

This study is the first to document significant age-related pathologies in endangered captive Julia Creek dunnarts, highlighting hormonal dysregulation and reproductive issues in females, while males exhibited higher occurrences of cutaneous diseases and testicular degeneration, providing valuable insight for conservation efforts.

Amenorrhea is relatively rare and initial testing should check FSH, TSH, and prolactin levels.

In this study, researchers developed a sensitive assay to measure the inhibition of steroid 5-α reductase (5AR) by chemicals like finasteride and dutasteride, revealing species-specific differences in inhibitor efficacy between human and fish cell lines.

This study found that polyamine levels in hair samples differ between androgenic alopecia and alopecia areata, suggesting potential non-invasive biomarkers to distinguish between these hair loss conditions.

This case report suggests a potential link between the intake of Serenoa repens, commonly known as Saw palmetto, and the onset of erectile dysfunction.

This study observed very high thallium levels in small mammals near a zinc smelter in Poland, accompanied by severe population and health impacts.

This article contains no new research findings and does not create or analyze any new data.

This study observed that management practices affect alopecia and hair cortisol in captive rhesus monkeys, with variations in these effects between different facilities.

This review discusses the use of hair analysis for examining stress and reproduction hormone levels in wildlife and highlights the need for more comprehensive physiological validations across species.

In this study, researchers observed that fasting-induced molting in laying hens led to increased thyroid hormones, which may regulate feather molting by affecting hair follicle growth through specific signaling pathways, highlighting molecular changes during induced molting.

This review discusses the use of hairs and feathers as defensive tools through toxin incorporation in certain mammals and birds and reports no new experimental findings.

This study found that patients with alopecia areata exhibited higher ratios of neutrophils-to-lymphocytes and eosinophils-to-lymphocytes compared to controls, suggesting potential markers for disease prediction and management.

This study used whole-genome resequencing to analyze genetic diversity and selection in 17 rabbit breeds, identifying genes linked to traits like coat color and body size, which could inform breeding and conservation efforts.

This review discusses adrenal gland disease in ferrets, exploring its signs, potential contributing factors, and current treatment options, but it reports no new clinical results.
