This study found that measuring reproductive hormone levels in brown bear hair may effectively support non-invasive genetic sampling, though larger samples or more sensitive techniques are needed for broader application.

This review examines dandruff and seborrheic dermatitis, highlighting the role of Malassezia yeasts in inflammation and hyper-proliferation, and reports no new clinical findings.

This study developed a new method using ultrahigh-power sonication and mass spectrometry to improve protein extraction from hair shafts, identifying 239 differentially expressed proteins related to fetal growth restriction, which were validated as potential noninvasive biomarkers for perinatal diagnostics.

This study developed a sensitive and precise scFv-based ELISA for miroestrol quantification, aiding quality control in P. candollei plant materials and health supplements.

This study developed an ultrahigh-power sonicator to improve protein extraction from hair shafts, followed by advanced proteomic analysis, identifying 239 differentially expressed proteins in fetal growth restriction cases compared to healthy controls, which were validated as potential biomarkers for perinatal diagnostics.

This study found that methanol is more effective than isopropanol at removing external cortisol from grizzly bear hair and suggests that the choice of solvent can influence hair cortisol concentration results.

This report discusses guidelines for designing alopecia clinical trials that account for variables affecting results, but it presents no new efficacy findings.

Antisense oligonucleotides show promise for treating Myotonic Dystrophy type I.

This study identified somatostatin as a potential secretory factor contributing to the immune privilege of human hair follicles.

In this study, oil body-bound oleosin-rhFGF-10 was more efficiently absorbed through the skin and enhanced wound healing and hair growth in mice, compared to prokaryotically-expressed rhFGF-10.

This study found that hair testosterone concentrations show some consistency over time, but factors like hair washing and individual growth rates influence these levels, suggesting the need for careful sampling and analysis adjustments.

This study developed a new method for detecting 30 hormones in anti-aging functional foods, demonstrating good sensitivity and reliability, and identified seven hormones in four out of 14 samples tested.

The new method can measure sleep-related hormones in hair effectively and could help track long-term sleep patterns.

This study developed a reliable HPLC-UV/Vis method to determine aluminum phthalocyanine chloride in skin, supporting its use in skin permeation studies for photodynamic therapy of cutaneous tumors.

This study developed and validated a simple, precise, and cost-effective UV spectrophotometric method for quantifying Minoxidil in bulk and pharmaceutical forms, reporting high accuracy with recovery rates between 99.57% and 100.55%, and a correlation coefficient of 0.9993.

This study found that female Holdobaggy goslings have higher melanin content in their dorsal plumage than males, suggesting that initial plumage color can be used for sex identification.

This article discusses various mechanisms for promoting hair growth in pattern hair loss and highlights the challenge of balancing short-term measurable results in trials with the need for long-term efficacy data.

This study observed that in privately owned, intact cats, male cats exhibited significantly higher long-term hair cortisol concentrations compared to females, while environmental and behavioral factors did not significantly impact cortisol levels, suggesting individual traits may influence stress markers more than external factors.

In this animal study, finasteride was found to significantly lower cortisol and increase testosterone levels in female rats, indicating its broader impact on endocrine regulation by altering adrenal and gonadal hormones.

This study developed a liquid chromatography with tandem mass spectrometry method to detect sex hormones in health supplements from Hanoi, Vietnam, finding three out of 16 samples contained sex hormones, including banned testosterone at low levels (~0.5 mg/kg).

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

This study reported the development of a novel and reliable liquid chromatographic method to measure testosterone and epitestosterone in human urine, offering sensitive detection for doping control.

Method accurately measures finasteride in tablets using finasteride-BSA interaction.

In this study, women with polycystic ovary syndrome showed significantly higher levels of DHEA, IL-6, and TNF-α compared to healthy controls, indicating a possible link between these biomarkers and PCOS.

This study found that human hair follicle dermal papilla cells and keratinocytes self-assembled differently in 3D spheroid co-cultures, providing insights into cell distribution and organogenesis during skin regeneration.

This review compiles existing research on ischemia-modified albumin (IMA) as a biomarker for myocardial ischemia, highlighting current gaps in understanding its formation and detection, with no new clinical results reported.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This study found that finasteride treatment improved cardiac function and reduced heart failure progression in mice, suggesting it could be a potential therapy for pathological cardiac hypertrophy and dysfunction.

This study found that finasteride treatment in male rats led to enduring effects on depressive-like behavior, hippocampal neurogenesis and neuroinflammation, and gut microbiota composition after withdrawal.
