This study found that acid regulation of the TRPV3 channel can inhibit its function from outside the cell while facilitating it from inside, providing insights into skin barrier and disorder mechanisms related to tissue acidosis.

Hair amino acid levels can indicate metabolic disorders.

This review discusses the diagnostic challenges of androgen and estrogen-secreting adrenal tumors and highlights that the presence of metastases is the most reliable indicator of malignancy; it reports no new clinical findings.

In this study, copper was found to promote the proliferation of dermal papilla cells in Rex rabbits by maintaining the function of the cellular mitochondrial electron transport chain.

This review summarizes a 15-year collaboration on the role of synaptic-like vesicles in mechanosensory nerve terminals and suggests potential therapeutic implications for conditions like hypertension and muscle spasticity.

This review discusses trichotillomania, including its diagnosis and management, and emphasizes the importance of a psychiatry-dermatology liaison alongside behavioral therapy and pharmacological options.

This study identified the same N-terminal and C-terminal amino acids in human and horse hair as previously found in wool and feather keratin.

This paper discusses the complex interplay between Long Covid symptoms and various chronic fatigue-related conditions but reports no new clinical findings.

This study observed that hair fibers in older women become more curved with age, decreasing hair luster due to their disordered alignment and structural differences between the convex and concave sides.

In this report, an 18-year-old female with trichotillomania was successfully treated using the glutamate modulator n-acetylcysteine.

This review discusses the role of microglia in mediating prenatal androgen effects on the female brain, potentially contributing to PCOS development and neuroendocrine dysfunctions, but reports no new results.

This study reported that novel kainate derivatives, especially ZCZ90, maintained potency in affecting proprioceptive sensory organ firing, aiding future receptor studies for potential treatment innovations.

This study found that cysteine and arginine are crucial for hair growth in hair follicles, with cysteine affecting hair fibre diameter and arginine involved in protein incorporation and energy metabolism.

This systematic review found that cinnamon supplementation may modestly improve insulin sensitivity and potentially reduce hyperandrogenism in women with PCOS, but stresses the need for large-scale clinical trials.

In this study, cats fed trace minerals complexed with lysine and glutamic acid displayed temporary improvements in hair loss and dander scores at 45 days, compared to those receiving inorganic trace minerals, although no differences were seen by day 90.

In this review, researchers analyzed literature on trichotillomania and found advances in understanding its neurobiology—highlighting dysregulated reward circuits and genetics—and treatments, with behavioral therapy and innovative pharmacological approaches improving outcomes where traditional SSRIs do not.

This review highlights advances in understanding trichotillomania's neurobiology and treatment, noting behavior therapy's effectiveness and new pharmacological and digital therapies, while addressing underdiagnosis, stigma, and research gaps.

In this literature review, researchers highlighted that trichotillomania involves dysregulated reward circuits, abnormal sensory processing, and potential genetic factors, advancing both therapeutic strategies and understanding of the condition, but stigma and provider training gaps persist in effective care provision.

This study found that the transcription factor Meis2 regulates the maturation and innervation of sensory neurons in mice, affecting their response to light touch.

This study found that boosting the synthesis of neural-derived 17β-estradiol effectively counteracted the impairment of hippocampal long-term potentiation caused by amyloid beta 1-42 in rat hippocampal slices, with the effect seemingly linked to glutamate NMDAR signaling.

This study found that ferulic acid significantly reduced seizure susceptibility and depression-like behaviors in a mouse model of catamenial epilepsy, likely by restoring hormone levels and neurotransmitter activity.

This study suggests that human hair follicles may operate their own Cori cycle, synthesizing glycogen from lactate under conditions of lactic acidosis.

Researchers discovered potential origins and new treatments for skin cancer, including biomarkers for melanoma and therapies that reduce tumor growth.

This ex vivo study found that hair follicles in female pattern hair loss exhibited nutrient insufficiency and dormant metabolism, but maintained nutrient uptake capability, suggesting potential benefits of nutritional supplementation as an adjunct therapy.

This research found that the transfer reaction catalyzed by human plasma and guinea pig hair follicle transglutaminases aligns with a ping-pong mechanism involving peptide-bound glutamine.

This study observed that glycine inhibited root growth and stimulated root hair development in habanero pepper seedlings, with ethylene signaling suggested to mediate these effects.

This study found that hair follicle-specific keratins can form different structural assemblies depending on ionic conditions, with hair cortex keratins requiring physiological salt conditions to form intermediate filaments.

In this study involving rats with letrozole-induced polycystic ovary syndrome, Agaricus subrufescens significantly reduced blood glucose, total cholesterol, testosterone levels, and renal markers, suggesting its potential protective effects on both metabolic and reproductive parameters.

This study investigated the sub-acute toxicity of Eclipta alba extract in Wistar albino rats, finding generally comparable hematological and biochemical parameters to controls, but noted mild morphological liver and kidney changes at the highest dose, highlighting a key area for further safety research.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.
