This review discusses severe insulin resistance syndromes, highlighting their diagnostic challenges, potential novel therapies like leptin replacement, and suggests metformin and lifestyle changes in its absence; no new clinical results are reported.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

This study found that altering neonatal neurosteroid levels affected anxiety and aversive learning in adult rats, possibly through changes in hippocampal GABAergic functions.

This study concludes that rhesus macaques are a suitable model for testing the pharmacological properties of finasteride and other 5aR inhibitors, due to their biochemical similarity to humans.

In this study, HIIT increased adiponectin levels and improved cholesterol profiles in women with PCOS, but did not change leptin or vaspin levels.

This study found that high-dose cyproterone acetate was effective for treating hirsutism, but 33% of patients felt their condition worsened on low-dose maintenance therapy, despite no significant change in objective measures of hair growth.

This study examined variations in epidermal thickness and protein expression across different dog breeds, finding significant differences by anatomical site and breed, with associated mRNA and protein expression changes observed.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

Among women with hirsutism studied, this research found a high prevalence of acne, particularly associated with polycystic ovarian syndrome and endocrine changes.

This study found that thyroid volume was increased in PCOS patients with insulin resistance, with potential influences from TSH and LH levels on these changes.

This review describes therapeutic strategies for polycystic ovary syndrome, highlighting current treatments for ovulation induction and emphasizing lifestyle changes and personalized approaches, but reports no new clinical results.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

The researchers reported a case of Beau's lines in a 65-year-old man, potentially linked to past severe COVID-19 infections, suggesting that identifying these nail changes might signal prior infection and increased risk of reinfection.

This study found that Sinja Valley residents possess traditional knowledge of 13 edible oil-producing plant species, yet this knowledge is at risk due to sociocultural changes. Despite its benefits, including treating disorders like gastritis, use of indigenous oils is declining as commercial products become prevalent.

This study found that skin surface lipids contain measurable mRNAs, providing a non-invasive way to study skin diseases, with specific gene expression changes observed in atopic dermatitis patients.

This study found that L-cystine-modified rabbit hair fibers had improved dye adsorption and spinnability, due to changes in secondary structure and surface characteristics.

This study found that combining second-harmonic generation with optical coherence tomography may effectively evaluate wound healing by monitoring collagen formation and optical signal changes in regenerated tissue.

In this study, while young rats fed a commercial standard diet with possibly deteriorated oil showed normal growth, they also exhibited liver surface changes and altered serum lipid levels compared to those on a defined diet.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

This case report highlights the challenges in diagnosing simple-virilizing congenital adrenal hyperplasia, emphasizing the importance of early expert evaluation to prevent irreversible changes such as virilization.

In this study, hirsutism was the most prevalent skin manifestation among women with PCOS, and a significant association was observed between certain skin changes and hormonal abnormalities such as insulin resistance and elevated prolactin levels.

This study found that experimentally induced hypothyroidism in rats is associated with impaired skin structure, but topical application of triiodothyronine (T3) improved these changes to resemble normal skin.

This study found that COVID-19 infection disrupts spermatogenesis, alters testicular cell populations, and may impact male fertility by causing long-term changes in testicular function and reduced sperm quality, as observed even in patients who have recovered from the acute phase of the infection.

In this case report, a 42-year-old woman with hypothyroidism showed improvement in symptoms like fatigue and hair loss after following an Ayurvedic regimen including Kunjal Kriya, Yoga, and diet changes alongside her regular medication, though further clinical studies are recommended to validate these findings.

This review discusses the symptoms, causes, and treatment options for polycystic ovary syndrome and reports no new results; the authors highlight the role of lifestyle changes, medications, and fertility treatments.

In this study, feeding H-line chickens a diet with 1.0% tyrosine for 40 days significantly increased melanin deposition in feathers and revealed changes in gene expression related to melanin pathways, suggesting tyrosine's involvement in regulating feather color through the EDNRB2 regulatory network.

In this randomized, placebo-controlled study, Kūlaris supplementation significantly improved quality of life for participants with mild-to-severe acne over 12 weeks, though no significant changes in general skin health measures were observed compared to placebo.

This review investigates how selenium, a trace element found in wheat, may impact hair health by examining its biochemical role in hair follicle biology and its potential therapeutic and toxicological effects.

This article discusses the challenges in diagnosing and treating polycystic ovary syndrome in adolescents, emphasizing the importance of lifestyle changes and a systematic therapeutic approach but reports no new clinical findings.

This study found that TRM21 acts as a positive regulator of flavonoid biosynthesis at the translational level in Arabidopsis, leading to changes in root hair growth and a decrease in flavonoid content when TRM21 is mutated.
