This study found that finasteride significantly reduced serum dihydrotestosterone levels, confirming its efficacy as a 5a-reductase inhibitor, while Permixon showed no effect in healthy male volunteers.

This study found that 54% of participants with androgenetic alopecia using Ricapil® showed clinical signs of hair follicle reactivation and initial hair regrowth over three months.

This study found that liarozole is more effective than cyproterone acetate for improving PSA response and survival in metastatic prostate cancer after first-line endocrine therapy, while maintaining quality of life.

This study found that neonatal administration of allopregnanolone enhances, while finasteride suppresses, the effects of adult intrahippocampal pregnenolone sulphate on rat locomotor activity in an open field test.

This study identified ten novel compounds that may effectively target steroid 5 alpha-reductase 2 (5αR-2) for potential treatment of benign prostate hyperplasia, exhibiting comparable binding energies to existing drugs like finasteride and dutasteride.

This case study observed that discontinuing risperidone reduced elevated prolactin levels and improved hair thinning in a 77-year-old woman, suggesting risperidone-associated telogen effluvium as a consideration in similar cases.

In this case report, goserelin, a GnRH agonist, was effective in managing stuttering priapism and improving erectile function in a patient with sickle cell disease, suggesting potential for last-line treatment.

In this study, dutasteride treatment in retinitis pigmentosa mice increased photoreceptor survival and reduced glial activation, suggesting it may offer a neuroprotective effect.

Deep Brain Stimulation helps manage Parkinson's symptoms when medication isn't enough.

In this study, patients with alopecia areata who didn't initially respond to ritlecitinib at Week 24 showed improved response rates by Week 48, with up to 34% achieving better hair regrowth outcomes.

This study reported that in rat retinas under high pressure, allopregnanolone synthesis increased and helped reduce pressure-induced damage through GABAA receptors, suggesting potential therapeutic use in glaucoma.

This study found that in a rat model, 14,15-EET may alleviate central poststroke pain by enhancing thalamic inhibition through neurosteroid signaling, potentially outperforming gabapentin in early-stage treatment.

This protocol outlines a planned Cochrane Review to evaluate the effects of 5-alpha-reductase inhibitors on lower urinary tract symptoms caused by benign prostatic obstruction, and it reports no new findings.

Ritlecitinib significantly regrows scalp hair in people with alopecia areata.

In this study using a macaque model, RU58841 at a 5% concentration significantly increased hair density, thickness, and length in the frontal bald scalp over six months.

In this study, researchers found that ginsenoside Re from Panax ginseng increased hair shaft length and duration in mice, comparable to minoxidil, by modulating TGF-β signaling pathways.

In this study, ritlecitinib 50 mg produced clinically meaningful improvements in scalp hair regrowth over three years for patients aged 12 and older with severe alopecia areata, with 65.1% showing substantial hair regrowth and 31.2% achieving complete regrowth, while also maintaining a consistent safety profile.

This study reports that ritlecitinib 50 mg, with or without an initial loading dose, demonstrated meaningful and sustained efficacy up to 24 months in the Asian subpopulation with severe alopecia areata, showing significant scalp, eyebrow, and eyelash hair regrowth, along with an acceptable safety profile.

This letter to the editor raises concerns about minoxidil, an arterial vasodilator also used for androgenic alopecia, noting that overdose can cause severe side effects such as distributive shock, pulmonary edema, and myocardial ischemia.

This study found that in newborn rats, progesterone's effects on apnoea frequency are influenced by a sex-specific balance between its metabolite allopregnanolone and progesterone receptors.

This source explains that Equine Cushing’s disease, or PPID, in horses is due to the degeneration of brain cells producing dopamine, leading to elevated cortisol levels and characteristic symptoms; it outlines diagnosis methods and emphasizes life-long pergolide treatment to manage the condition.

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.

This study found that inhibiting the 5alpha-reductase 2 pathway in male rats affects brain sexual differentiation and leads to reproductive changes, including increased pre-implantation loss despite unchanged copulatory potential.

This review discusses the use of Serenoa repens for benign prostatic hyperplasia symptoms, noting similar efficacy to other treatments but highlights the need for further rigorous trials to confirm effectiveness.

In this review, the authors highlight the FDA approval of Ritlecitinib, the first oral treatment specifically for moderate to severe alopecia areata in patients aged 12 and older, marking a significant advancement in managing this condition.
