This study found that age-related fluctuations in hormones and endocannabinoids in male C57BL/6 mice showed specific patterns, with peak values observed around 2.7 to 3.4 months, with these patterns seen in both plasma and hair but with different magnitudes.

This study observed that pelage development in male blue foxes born in early June was more synchronized than those born in early May, with differences likely influenced by melatonin levels.

This study found that the retinoid receptor and PPAR pathway are involved in hair follicle miniaturization in androgenetic alopecia, alongside androgen receptors.

This study found that hair samples from chronic tramadol and cannabis users showed positive drug presence for 3-4 months and 6-7 months, respectively, after discontinuation.

This study found that hair sample weight was a better predictor of hair cortisol concentration than hair protein concentration, suggesting that using the standard cortisol-to-weight ratio is more suitable for measuring cumulative cortisol activity in scalp hair.

This review covers the basic principles of forensic hair analysis, including how chemical substances get incorporated into hair, and emphasizes its applications in disease diagnosis, without providing new experimental results.

The method effectively maps lead and zinc in hair, aiding understanding of heavy metal exposure risks.

This study observed significant differences in hair and cashmere properties among three goat breeds in Southwest China, noting better quality cashmere in Inner Mongolia cashmere goats and their crossbreed compared to Dazu black goats.

The conclusion is that a new method can measure caffeine and drugs in hair, finding caffeine abusers have 70 times more caffeine than normal, with a proposed cut-off value for abuse.

This study suggests that analyzing hair samples with a liquid chromatography-mass spectrometric assay may offer a reliable method to measure average quarterly vitamin D levels, potentially complementing blood tests.

In this study, researchers found that targeting a tacrolimus trough level of 4–7 ng/mL after liver transplantation resulted in comparable graft and patient survival rates to higher levels, while improving liver and kidney function markers.

This study suggests that collecting hair samples from all scalp regions may be a viable alternative for measuring cortisol in individuals with Afro-textured or extremely short hair, aligning results with traditional methods.

This study found that chronic administration of finasteride affected the isotopic composition of testosterone and nandrolone metabolites, impacting the drug-testing outcomes in athletic contexts.

This article reviews analysis techniques in LC-MS/MS and discusses the potential use of a novel in-sample calibration curve method, but reports no new experimental results.

This study found that Magra sheep with high-luster wool exhibited significantly higher expression of keratin genes, suggesting that increased keratin protein levels may be crucial for wool luster.

This collection from the 2021 Manfred Donike Workshop outlines advancements in doping detection, highlighting new test methods and challenges, with a focus on steroidal substances, peptide hormones, and gene doping analysis.

This article reviews the causes and diagnostic approaches for feline alopecia, emphasizing the importance of distinguishing between self-inflicted and spontaneous hair loss, but reports no new results.

Women's hair has more sulfur, and black hair has more calcium than white hair.

This study developed and validated a method for measuring stress biomarkers in hair during pregnancy, finding that glucocorticoid levels increased over trimesters while endocannabinoid levels remained constant, suggesting hair analysis as a reliable tool for monitoring stress responses in pregnant women.

This paper provides an auditable companion package for their exploratory re-analysis of miRNA dysregulation and target enrichment in female pattern hair loss cases, focusing on candidate-level results from a public dataset comparison between affected individuals and healthy controls.

In this study, researchers conducted an exploratory re-analysis of miRNA dysregulation and aging-related target enrichment in female pattern hair loss using data from public GEO dataset GSE106780. The findings are preliminary and should be interpreted as candidate-level results due to the small sample size.

Cortisone and cortisol levels in pregnant women’s hair increase as labor approaches, indicating higher stress.

This study identified distinct immune differences in patients with alopecia areata, particularly those with atopic backgrounds, and highlighted the OX40 axis as a potential therapeutic target for the condition.

This study analyzed inner root sheath-specific genes in Tan sheep during various growth stages, finding peak expression at birth. The pattern of genes KRT71, KRT72, and TCHH is consistent with wool crimp, potentially influencing wool morphology.

This study used hair samples to assess mineral levels and found that higher iron status may be associated with an increased risk of esophageal squamous cell carcinoma, while no significant associations were observed for copper and magnesium levels in this cohort.

Homemade hair treatments can significantly lower drug levels in hair, possibly causing false-negative drug tests.

According to this study, forensic DNA phenotyping using Next Generation Sequencing can reliably predict certain visible traits like eye, hair, and skin color, though its routine implementation in forensics is hindered by incomplete genetic knowledge and ethical concerns in some countries.

The researchers observed that vitiligo-affected skin shows a selective depletion of NTRK2+ melanocyte subpopulations with progenitor features, which may contribute to poor treatment responses.

This study found that women with chronic telogen effluvium had significantly lower levels of zinc, copper, and ferritin in their serum compared to healthy controls.

This article discusses the diagnostic approach to focal alopecia in dogs, focusing on distinguishing between pruritic skin disease and inflammatory or non-inflammatory causes; it presents no new experimental results.
