In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This article reviews the effects of various medications on male fertility, noting that while commonly used drugs can mostly have reversible impacts, conclusive human evidence remains limited.

The study observed that finasteride reduced fertility in male Sprague-Dawley rats by impairing the formation of copulatory plugs, an effect considered specific to rats and not applicable to species without this reproductive feature.

This study presented a new two-dimensional model that successfully predicts transdermal permeation of caffeine, highlighting the significant role of the follicular pathway in increasing systemic bioavailability.

Hairless mice lack fur due to a genetic mutation affecting skin response, not hormone issues.

This study found that inadequate maternal pyridoxine during pregnancy led to lower body weight, slow physical development, and impaired neuromotor development in rat pups, with the severity increasing as pyridoxine levels decreased.

In this study, researchers found that overexpression of IGF-1 in transgenic mice stimulated increased vibrissa growth during the first neonatal hair cycle compared to their nontransgenic littermates.

In this study, researchers identified a novel congenital skin disorder in Chesapeake Bay retrievers, linked to a plakophilin-1 deficiency due to a genetic mutation, marking the first known occurrence in an animal species.

Finasteride temporarily lowers male rat fertility without affecting libido.

Finasteride affects prostate weights and pituitary activity differently with age.

This review discusses the diagnosis and treatment of iron deficiency, its potential link to hair loss, and emphasizes the importance for dermatologists to understand these aspects; it reports no new findings.

In this laboratory study with rats, treatment with finasteride reduced dihydrotestosterone levels and fertility parameters, with a 30-day recovery period proving insufficient to fully restore sperm function and fertility.

This study reported intra-familial transmission of Arthroderma benhamiae among Canadian porcupines in a Japanese zoo, with genetic sequences previously undocumented in Japan or the GenBank database.

This review analyzes how androgens impact sexual desire and reproductive behaviors, emphasizing molecular interactions, but provides no new clinical results.

In this study, D-004 did not affect androgen-dependent development in rats exposed in utero, while finasteride caused significant changes in male offspring's androgen-dependent tissues.

In a study using a mouse model, HF-MSCs were reported to enhance ovarian function in cyclophosphamide-induced premature ovarian failure more effectively than HU-MSCs, potentially by preventing ferroptosis in granulosa cells via the KEAP1/NRF2/HO-1 pathway.

This study identified the Itpr3 gene as responsible for the tufted hair loss phenotype in the BTBR mouse strain.

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

This review examines host factors like ACE2 and TMPRSS2 in SARS-CoV-2 infection, exploring how genetic variants and advanced cellular analyses might clarify COVID-19's severity and heterogeneity; it reports no new results.

Antiandrogen therapy may be beneficial for women with hidradenitis suppurativa.

This article argues against the widespread use of isolated frontal forelock hair transplantation for most patients, suggesting more extensive coverage is often a reasonable option.

This book compiles papers from a 1988 symposium on human hair follicle research, highlighting collaboration between dermatology and industry, but reports no new clinical findings.

This study found that mink pelts with "singe" and "red hip" defects often exhibit split hair tips and altered cuticle structures, which may contribute to their undesired metallic sheen.

This study found no correlation between clinical signs and sex steroid levels in ferrets with hyperadrenocorticism and noted that androstenedione was elevated in many cases.

This chapter discusses genetic polymorphisms related to phenotypes that differentiate between populations and reports no new results; it highlights the role of DNA technology in understanding human adaptation history.

This study found that androgenic hormone levels did not explain growth differences between furless and furred male rabbits, despite a potential growth advantage in furless rabbits.

In this article, the author reports a case where hemiballismus was almost completely suppressed within 48 hours of starting haloperidol therapy, suggesting a therapeutic response to the drug.

This study found that higher dihydrotestosterone (DHT) levels are associated with reduced crowing complexity in Kokok Balenggek roosters.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.
