In this study, feeding H-line chickens a diet with 1.0% tyrosine for 40 days significantly increased melanin deposition in feathers and revealed changes in gene expression related to melanin pathways, suggesting tyrosine's involvement in regulating feather color through the EDNRB2 regulatory network.

This study explores the potential of platelet-rich plasma (PRP) as a novel adjuvant therapy for eczema, positing that it may alleviate inflammation, enhance skin barrier function, and reduce recurrence.

This study presents a two-photon imaging method to visualize low-threshold mechanoreceptor axon terminals in live mouse forepaw skin, enabling repeated high-resolution imaging to study sensory circuits during development and adulthood.

This study utilized a mouse model of traumatic brain injury to reveal that acute neurotrauma triggers widespread lipid metabolism reprogramming and storage lipid accumulation in microglial and monocyte populations, leading to lysosomal dysfunction, inhibited autophagy, and exacerbated inflammation through a pathological feedback loop.

This study found that intrinsic feedback loops are crucial for maintaining the function of human dermal papilla cells during hair growth, highlighting the importance of autocrine signaling and niche reprogramming for advancing hair follicle biology and regenerative therapies for hair loss.

This study found that 62 plasma proteins are significantly associated with the risk of obstructive sleep apnea, offering potential targets for new therapeutic strategies.

This study identified key genes and pathways involved in the growth and development of forest musk deer hair follicles, providing insights into molecular regulation and laying groundwork for future research on related diseases.

This study found that repeatedly collecting hair follicles from individuals with fragile X syndrome is feasible for measuring FMR1 and FMRP levels in both home and office settings.

This review discusses the association between hair element levels and autism spectrum disorder, reporting links between neurotoxic elements like mercury and lead and pathogenesis, alongside potentially protective roles for zinc and copper balance.

This study found that neonatal administration of finasteride reduced sensitivity to alcohol's motor-stimulating effects and increased preference for novelty and initial alcohol consumption in rats, suggesting a role in alcohol vulnerability.

This case study reported an improvement in lower limb edema for a patient with type 2 diabetes mellitus after starting dulaglutide treatment, suggesting a potential role of the drug in sodium retention disorders.

This study found that inhibitory neurosteroids synthesized within glial cells can reduce seizure frequency in epileptic animals by enhancing inhibitory transmission via γ-aminobutyric acid receptors.

This study found that exogenous glutamic acid can promote hair growth and keratinocyte proliferation, suggesting a novel signalling pathway in the skin.

This study observed that deleting PTEN in mouse facial motoneurons enhanced peripheral axon regeneration but also led to physiological changes and potential hyperplasia in older mice.

This article discusses the role of zinc in reducing depression severity and reports no new research findings, emphasizing the need for further investigation into its therapeutic potential.

This study suggests that low level laser therapy may promote hair cell regeneration in rat cochlear explants following gentamicin-induced damage.

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.

This study found that in Liaoning cashmere goats, overexpression of the PIP5K1A gene enhances skin fibroblast proliferation, while interference with this gene reverses melatonin-induced proliferation, and PIP5K1A regulates certain miRNA expressions, suggesting a role in improving cashmere yield and quality.

This review discusses the progress in identifying stem cells responsible for tissue regeneration and highlights technological advances in tracking their behavior, but reports no new clinical results.

This review discusses the pharmacological properties and physiological regulation of neuroactive steroids, focusing on their varied responses to stress and ethanol in rats, mice, and humans, but it reports no new findings.

This study found that pharmacological inhibition of sex steroid synthesis impacts pathogenic processes in traumatic brain injury in a sex-specific manner, with distinct effects of letrozole and finasteride on molecular and neurological outcomes.

In this study, finasteride was found not to be associated with changes in sleep spindle activity or morphology in men undergoing sleep studies.

This review discusses the neurobiology of sexual function and reports no new results; the authors cover multiple endocrine and neurotransmitter influences on sexual desire, arousal, and orgasm stages.

This review discusses the potential impact of endocrine-disrupting chemicals and body size on pubertal onset and progression, highlighting critical gaps and priorities for future research without presenting new clinical results.

This study observed that acute stress in rats increased neurosteroid levels linked to enhanced GABA(A) receptor function, raising seizure thresholds, while similar effects were seen in mice with deoxycorticosterone administration.

This study found that neurosteroids can reorganize GABA A receptors in mice, mimicking ovarian cycle changes, with the process being mediated by neurosteroid levels rather than direct hormone receptor activation.

This review discusses the roles and mechanisms of chromatin remodelers and their subunits in mammalian development, but reports no new experimental results.

This review discusses the development and potential therapeutic applications of adenosine receptor agonists and positive allosteric modulators, noting that while many clinical trials have been unsuccessful, initial results for new compounds are promising.

This review summarizes proposed pathophysiological mechanisms of postpartum depression, highlighting neuroendocrine and neurobiological changes, but reports no new findings and calls for integrated understanding of the disorder.

In this study, researchers used genetic data from over 52,000 men to identify over 250 genetic loci associated with severe hair loss and developed a predictive algorithm for determining hair loss risk.
