research Surrogate end-points or primary outcomes in clinical trials in women with polycystic ovary syndrome?
The document suggests that clinical trials for PCOS should focus on meaningful primary outcomes like live birth rates, rather than less reliable surrogate markers.
research Systematic review of platelet-rich plasma (PRP) preparation and composition for the treatment of androgenetic alopecia
PRP shows promise for hair loss treatment, but needs standardized preparation and composition.
research Profile of tofacitinib citrate and its potential in the treatment of moderate-to-severe chronic plaque psoriasis
Tofacitinib citrate is effective for moderate-to-severe chronic plaque psoriasis but has safety concerns at higher doses.
research Human hair keratins promote the regeneration of peripheral nerves in a rat sciatic nerve crush model
Human hair keratin helps repair nerve damage in rats.
research CC-type glutaredoxins mediate plant response and signaling under nitrate starvation in Arabidopsis
ROXY proteins help plants respond to nitrate shortage by affecting nutrient sensing and growth.
research Efficacy of Topical Combination of 0.25% Finasteride and 3% Minoxidil Versus 3% Minoxidil Solution in Female Pattern Hair Loss: A Randomized, Double-Blind, Controlled Study
Combination of 0.25% finasteride and 3% minoxidil works better than just 3% minoxidil for increasing hair thickness in women.
research Vasoactive intestinal peptide, whose receptor-mediated signalling may be defective in alopecia areata, provides protection from hair follicle immune privilege collapse
A substance called VIP might protect hair follicles from being attacked by the immune system, and problems with VIP signaling could lead to hair loss in alopecia areata.
research Hair greying is associated with active hair growth
White hair grows thicker and faster than black hair due to higher activity of growth-related genes and proteins.
research A Review of the FAERS Data on 5-Alpha Reductase Inhibitors: Implications for Postfinasteride Syndrome
The review suggests younger men taking 1 mg finasteride report more side effects, including sexual, skin, metabolic, and psychological issues.
research Treatment options for alopecia: an update, looking to the future
The document concludes that there are various treatments for different types of alopecia, but more research is needed for evidence-based treatments.
research Repurposing existing drugs for COVID-19: an endocrinology perspective
Existing drug dexamethasone may lower death risk in severe COVID-19 cases; more research needed for other drugs.
research Hair Regenerative Mechanisms of Red Ginseng Oil and Its Major Components in the Testosterone-Induced Delay of Anagen Entry in C57BL/6 Mice
Red ginseng oil and its components help promote hair regrowth and could treat hair loss.
research Human Hair Follicle Stem/Progenitor Cells Express Hypoxia Markers
Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.
research Dietary supplementation with Essential-oils-cobalt for improving growth performance, meat quality and skin cell capacity of goats
Essential-oils-cobalt improves goat growth and product quality.
research FOXN1 deficient nude severe combined immunodeficiency
FOXN1 gene mutations cause a rare, severe immune disease treatable with cell or tissue transplants.
research The Role of Pannexin 3 in Bone Biology
Pannexin 3 is important for bone formation and the development of bone cells.
research Male Breast Cancer and 5α-Reductase Inhibitors Finasteride and Dutasteride
Using finasteride or dutasteride does not increase the risk of male breast cancer.
research Regenerative Effect of Intraovarian Injection of Activated Autologous Platelet Rich Plasma: Serum Anti-Mullerian Hormone Levels Measured Among Poor-Prognosis In Vitro Fertilization Patients
PRP treatment can safely boost hormone levels in some IVF patients with low ovarian reserve.
research Negative Impact of Testosterone Deficiency and 5α-Reductase Inhibitors Therapy on Metabolic and Sexual Function in Men
Low testosterone and 5α-reductase inhibitors can harm men's metabolic and sexual health; testosterone therapy may help, but discussing 5α-RIs' side effects is important.
research Stem Cell-Based Tissue Engineering for the Treatment of Burn Wounds: A Systematic Review of Preclinical Studies
Stem cell treatments may improve burn wound healing.
research Human hair follicles operate an internal Cori cycle and modulate their growth via glycogen phosphorylase
Inhibiting glycogen metabolism can promote hair growth.
research Characterisation of cell cycle arrest and terminal differentiation in a maximally proliferative human epithelial tissue: Lessons from the human hair follicle matrix
CIP/KIP proteins help stop cell division and support hair growth.
research Limitations of human occipital scalp hair follicle organ culture for studying the effects of minoxidil as a hair growth enhancer
Scalp hair follicle culture has limits for testing minoxidil's hair growth effects.
research Skin Penetration and Permeation Properties of Transcutol® in Complex Formulations
Transcutol® helps drugs penetrate the skin more effectively in various formulations.
research A randomized, investigator-blinded, controlled, split-scalp study of the efficacy and safety of a 1550-nm fractional erbium-glass laser, used in combination with topical 5% minoxidil versus 5% minoxidil alone, for the treatment of androgenetic alopecia
Laser and minoxidil combo promotes better hair growth than minoxidil alone, safely.
