Premature gray hair may indicate reduced ovarian reserve but doesn't lower pregnancy chances.

This study found that, among fertile egg donors, the AR gene CAG polymorphism was associated with differences in antral follicle count but did not impact ovarian response to gonadotrophins.

This review discusses the use of antimüllerian hormone as a marker of ovarian reserve in infertility diagnosis and treatment, noting it reflects oocyte quantity but not health or pregnancy likelihood.

This study found that intraovarian PRP treatment in women with low ovarian reserve was associated with significant increases in serum AMH levels in some patients, typically within four weeks.

This study found that a wound dressing made from egg white proteins, polyvinyl alcohol, and 1 mg/ml graphene oxide was most effective in promoting skin wound healing and tissue regeneration.

This article provides an overview of ovulation disorders, discussing ovarian, hypothalamic, and endocrine defects but reports no new clinical findings.

This study found that the natural extract e-CAF promotes the proliferation and migration of human hair dermal papilla cells in vitro, suggesting potential benefits for skin regeneration and tissue repair.

This study developed lipid-core nanocapsules for encapsulating menthol, improving its solubility and thermal stability, and demonstrated their safety and rapid skin absorption in ex vivo tests, highlighting potential applications for cosmeceuticals.

This study found that rats fed a diet with different protein qualities and levels showed significant differences in hair cycle length, daily weight gain, and hair density.

This review discusses the potential use of autologous platelet-rich plasma to enhance ovarian reserve by interacting with follicles and other ovarian components, and it reports no new clinical results.

In this study, supplementing ewes with soy hulls instead of a traditional corn-based supplement showed no impact on gastrointestinal nematode infection levels in hair sheep ewes managed in a pasture-based system, though some differences in packed cell volume at weaning were noted.

This study found that using a combined LH and FSH stimulation protocol significantly increased clinical pregnancy rates in women with low ovarian reserve compared to the standard protocol.

This study found no clinically significant effects of intraovarian injection of platelet-rich plasma on ovarian function over one year in patients with extremely low functional ovarian reserve.

This review discusses the roles of hair follicles and sebaceous glands in percutaneous transport and reports no new results, noting a lack of adequate models and methodologies.

This narrative review describes the components of human hair and their nutritional importance but reports no clinical results; the authors suggest dietary sulfur amino acids are essential for hair health.

This article reviews the role of micronutrients in athletes' diets, highlighting that adequate dietary intake generally meets their needs without requiring supplementation, unless deficiencies are present.

This study identified a new cis-regulatory element in the mouse Hr gene that influences its expression in skin and brain cells, highlighting a complex molecular network involved in hair follicle formation.

This review discusses the challenges and contradictions in understanding nanoparticle penetration and toxicity in human skin, emphasizing the need for standardized testing and further research on particles smaller than 10 nm.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

This study found that liposomes coated with cationic polymers, chitosan and Eudragit EPO, showed improved physicochemical stability and enhanced skin diffusion of aciclovir and minoxidil compared to uncoated liposomes.

In this review, the authors summarize the phytochemistry, pharmacology, and medicinal uses of Hibiscus rosa sinensis, highlighting its various benefits such as hypotensive and anti-inflammatory effects, while noting the need for more research on its specific mechanisms and potential toxicities.

A girl with Netherton syndrome was able to eat wheat without allergies after a special treatment.

In this study, exposure to the drug finasteride in Silurana tropicalis significantly increased testosterone levels in liver and testis tissues and altered gene expression related to male reproduction and oxidative stress.

This review discusses three aspects of cell fate specification across Metazoa and reports no new experimental results, highlighting the formation of nematode equivalence groups, evolution of echinoderm skeletogenic mesoderm, and adult cell fate regulation.

This research found that liquid-state liposomes and niosomes may enhance finasteride delivery to pilosebaceous units in hamsters more effectively than gel-state vesicles or hydroalcoholic solution.

This study demonstrated that phosphatidylcholine liposomes can deliver calcein and melanin into hair follicles and shafts in mice without significant penetration into the dermis, epidermis, or bloodstream.

This study found that adapalene-loaded solid lipid microparticles may enhance targeted drug delivery into sebum due to their similarity to sebum components, although both this formulation and a standard cream showed equivalent follicular penetration.

This review discusses the onset of menstruation and related challenges in young women, with a focus on primary amenorrhea, its diagnosis, and management strategies, and reports no new clinical findings.

This study found that maternal Nano-Se supplementation in cashmere goats improved antioxidant status and promoted secondary hair follicle development in fetuses at 110 days.
