This review discusses the multifactorial etiology of hypospadias, including genetic predispositions and possible environmental factors, and highlights the need for further studies on genetic and environmental contributions to its increasing prevalence, without presenting new findings.

This review discusses melanocyte biology and its genetic and molecular basis, highlighting its relevance in understanding diseases like vitiligo and albinism, and reports no new findings.

This paper discusses X-linked ichthyosis and its genetic causes, focusing on biochemical pathways and their role in epidermal differentiation and barrier function, but it presents no new clinical findings.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

This article reviews the role of stem cells in tissue development, tumor formation, and organoid generation, and highlights the potential of epigenetic regulation in advancing regenerative medicine and cancer treatment, without presenting new experimental results.

This case report highlights that a woman experienced arsenic toxicosis from kelp supplements, manifesting as alopecia and memory loss, which resolved after stopping the supplements.

This review explores the mechanisms of hair cell death due to factors like noise, ototoxic drugs, and aging and reports no conclusive clinical results; ongoing research may eventually enable preventive treatments for hearing loss.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This review discusses the importance of omega-3 fatty acids for human health and explores recent advancements in genetically modifying plants to produce these essential nutrients, but reports no new results.

This review examines the pathogenesis of premature hair graying and potential treatment avenues, but reports no new experimental outcomes, highlighting ongoing research challenges and hopes for drug development.

This review discusses lung regeneration and highlights the role of facultative stem/progenitor cells, but it reports no new findings and calls for further exploration of underlying mechanisms.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

This article reviews the role of diet in various skin disorders and suggests that dietary changes may aid in managing certain conditions, though it reports no new clinical findings.

This study found that chronic exposure to fadrozole or finasteride during frog development induced intersex individuals, which displayed different gene expression profiles depending on the chemical used.

This study reports that a sarcoptic mange outbreak, likely originating from mange-infected llamas from a governmental program, dramatically reduced vicuña and guanaco populations in San Guillermo National Park, Argentina.

This article discusses various potential health benefits and increasing global interest in astaxanthin but presents no new clinical results, though ongoing trials are exploring its effects on chronic diseases and other conditions.

This study found evidence of increased DNA methylation of the androgen receptor gene in occipital hair follicles from men with androgenetic alopecia.

This case report describes a 39-year-old woman whose dermatomyositis-systemic lupus erythematosus overlap syndrome symptoms resolved after switching to tofacitinib.

This review examines the diverse roles of SRD5α enzymes across species, focusing on their involvement in steroid synthesis, sexual development, and various physiological processes, but reports no new clinical results.

This study reports that variable environmental factors, including dietary habits, may contribute to the increasing incidence and diverse clinical presentations of frontal fibrosing alopecia.

In this study, researchers identified a gene expression pre-pattern and implicated the Wnt inhibitor Dickkopf 4 in the formation of color patterns in domestic cat embryos.

This study found that the methanolic heartwood extract of Avicennia marina significantly inhibits 5α-reductase type 1, reducing 5α-DHT production by 52% in a cell-based assay with human hair dermal papilla cells.

This article reviews the toxic effects of mimosine in Leucaena leucocephala and discusses various methods to mitigate its toxicity but presents no new findings.

This study found that exposure to finasteride impaired spermatogenesis in male Xenopus laevis by affecting sex-specific feedback mechanisms in the hypothalamus–pituitary–gonad axis.

This study found that higher levels of the protein Flii were associated with enhanced hair follicle regeneration and longer hair fibers in a mouse model.

This review suggests the existence of a new syndrome characterized by keratosis pilaris, ulerythema ophryogenes, and monosomy 18p, emphasizing its potential utility in diagnosing monosomy 18p.

This study found that ranitidine and finasteride may have cardiovascular and renal protective effects in mice by inhibiting TMAO synthesis and improving gut microbiota composition.

This animal study found that biscuits fortified with zinc oxide nanoparticles improved growth, appetite, and hair growth in zinc-deficient rats more effectively than traditional zinc forms, without apparent toxicity.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

In this study, silver foxes given a yeast "filtrate factor" supplement retained their fur and normal pelts, while those without it experienced fur loss and thymus abnormalities.
