In this study, PTH–CBD displayed dose-dependent effects in reducing hair loss and enhancing hair regrowth in a mouse model of chemotherapy-induced alopecia.

This study suggests that while hair analysis using GC-MS is a sensitive method for detecting cocaine ingestion, it may not reliably indicate the amount, timing, or duration of drug use due to interindividual variability and multiple incorporation mechanisms.

This study reports that alopecia may develop in patients with chronic exposure to high plasma concentrations of valproate, but resolved after dose reduction or treatment discontinuation.

This study found that Arc/Arg3.1 expression in hippocampal neurons is regulated by sex steroids in a sex-dependent manner, with E2 increasing expression in females and DHT in males.

This study found that in healthy young men, oral minoxidil at 5 mg/day led to increased carotid intima-media thickness and vascular aging, suggesting potential cardiovascular side effects at higher doses. A dose-dependent effect was observed, while dutasteride displayed a favorable vascular profile without significant changes.

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 a gene from hamster flank organs is indirectly regulated by androgens, despite lacking direct androgen responsive elements, indicating involvement of androgen-dependent transcription factors.

In this study, researchers found that while both beard and scalp dermal papilla cells release similar autocrine growth factors, only beard cells increased production and response with testosterone, suggesting these factors enhance androgen-induced hair growth.

This study established an androgen-responsive human organ culture model using hair follicles, demonstrating that women's intermediate facial follicles grow more hair in response to men's higher androgen levels.

This study examined the safety profile of ritlecitinib, a drug for alopecia areata, and found that it does not cause significant QTc prolongation or severe lymphopenia, with no unique safety risks expected in adolescents.

This study found that for people with androgenetic alopecia, increasing the dosage of low-dose oral minoxidil is associated with improvements in hair diameter and density, but also raises the risk of hypertrichosis and cardiovascular adverse events.

This study found that in mice, low-dose irradiation causes stem cells in hair follicles to undergo chromatin alterations, which may eventually lead to long-term functional loss in tissues or organs.

This study found that maternal consumption of a western diet in mice led to toxic milk production, causing inflammation and alopecia in nursing neonates due to Toll-like-receptor activation.

Bicalutamide may take longer to work for female hair loss, and higher doses might be needed.

In this pilot randomized clinical trial, TRT combined with finasteride increased lean mass, muscle size, and bone mineral density without prostate enlargement in men with spinal cord injury, suggesting potential benefits for body composition and musculoskeletal health.

Small hormonal imbalances can cause significant health problems, so more sensitive testing for hormone-disrupting chemicals is needed.

This study found that serine 44 in the N-terminal head domain of keratin 17 is phosphorylated in response to various stimuli affecting skin keratinocyte growth, linking K17 up-regulation with growth and stress responses in skin epithelium.

This study found that the protein OsUEV1B is essential for maintaining phosphate balance in rice, with Pi deficiency leading to its inhibition and causing overaccumulation of phosphate in mutants.

In this study, topical application of the SCD1 inhibitor XEN103 significantly reduced sebaceous gland size and number in mouse skin, suggesting potential local therapeutic effects for acne treatment without systemic side effects.

This review discusses the effects of photobiomodulation, particularly its potential to reduce inflammation in various conditions, but it does not report new clinical findings.

This paper discusses the role of steroid sulfatase in hormone-dependent tumors and highlights the development of potent inhibitors, noting the commencement of a phase I trial for one inhibitor in postmenopausal breast cancer patients.

This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.

This study found that dengue virus infection caused inflammation and cell death in human hair-follicle dermal papilla cells, which may contribute to increased hair shedding observed during the epidemic in Taiwan.

This study found that ethinylestradiol and high-dose cyproterone acetate significantly reduced hirsutism scores and were effective for treating acne and alopecia in women with hyperandrogenism.

This study found that low-dose methotrexate significantly reduced the steroid requirement in subjects with corticosteroid-requiring asthma without altering their clinical status or causing significant complications.

This case study reported that absence of alopecia does not reliably predict responsiveness to vitamin D treatment in Vitamin D-dependent rickets type II, as demonstrated by a patient with normal hair growth who showed extreme resistance.

This case study reports that ciclosporin effectively managed symptoms in a patient with steroid-dependent sudden sensorineural hearing loss, allowing discontinuation of corticosteroids and confirming remission through audiometry.

This study found that modeling and simulation effectively informed decision-making and dose selection for ritlecitinib in treating alopecia areata, supporting an accelerated drug development strategy.

This case report discusses a 27-month-old girl with vitamin D-dependent rickets type II, who showed minor improvement in skeletal features and alopecia after high-dose oral calcium and vitamin D3 treatment.

In this study, a novel VDR gene mutation was identified in a child with HVDRR, and the researchers observed that high-dose intravenous calcium therapy led to significant and sustained improvement in rickets symptoms.
