This review discusses the current understanding of polycystic ovary syndrome, focusing on its epidemiology, pathophysiology, diagnosis, management, and future research directions, but reports no new clinical results.

This article reviews the potential of PRP as a treatment for spinal pain but calls for established use guidelines and protocols before wider clinical adoption, with no new clinical results reported.

In this study, subclinical hypothyroidism in women with PCOS was linked to changes in the thyroid-prolactin axis and a lack of correlation between TSH and AMH, while gonadotropin levels and ovarian morphology remained unaffected, indicating the need for further prospective research.

This study used developing mouse hair follicles to explore early epithelial bud formation, finding that the Rho GTPase regulator ARHGEF3 plays a crucial role in regulating cell fate and cadherin patterning, with knockouts showing disrupted morphology and increased straight hair follicle growth.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This review explores the association between sleep disturbances, obstructive sleep apnoea, and metabolic consequences like Type 2 diabetes, but reports no new experimental results; the authors elaborate on existing knowledge and suggest complex interconnections with fat accumulation and various syndromes.

This study investigated a nanostructured system using PS-b-PAA diblock copolymer for incorporating the hydrophobic photosensitizer ClAlPc, finding it effective in causing cellular damage in Caco-2 cells under light while demonstrating no cytotoxicity without light, suggesting its potential use in photodynamic therapy.

This study explored using keratin extracted from human hair waste to create biodegradable bioplastic films, revealing promising potential for applications in packaging and disposable items due to their uniform surface morphology and ability to degrade with keratinophilic fungi.

In this study, administering 5alpha-reductase inhibitors reduced dihydrotestosterone levels and was associated with mild, reversible decreases in semen parameters in healthy men.

This study demonstrated a method for large-scale preparation of self-sorted hair follicle germs in vitro, which successfully generated hair follicles when transplanted into the skin of nude mice.

Pigs are a good model for studying human hair growth and disorders.

This study found that Lactobacillus acidophilus cell-free supernatant caused significant cytotoxicity, reduced migratory ability, and induced apoptosis in cervical cancer cell lines, suggesting its potential as a non-toxic adjunct therapy for cervical cancer.

This review suggests that dermatological cosmetic procedures can be safely performed on dark-complexioned skin with appropriate treatment adjustments, highlighting the need for careful consideration to prevent adverse effects.

The April 2014 issue of "Fertility and Sterility" discussed various reproductive health topics, including hormone therapy benefits, sperm and genetic factors in male infertility, and the link between PCOS and diabetes.

This study found that CRISPR/Cas9-mediated disruption of the FGF5 gene in goats increased hair follicle numbers and fiber length, suggesting more cashmere production could be achieved.

Oral retinoids are effective for severe skin conditions but require careful use due to side effects.

This case report describes a sarcoptic mange outbreak caused by Trixacarus caviae in a guinea pig breeding colony, which was successfully treated with subcutaneous ivermectin injections and preventive spraying.

In this study, managing laryngectomy patients during the COVID-19 pandemic requires special precautions due to their unique respiratory challenges, emphasizing the need for protective equipment and postponement of non-essential procedures to reduce infection risks for patients and health care providers.

This article discusses the complexities in diagnosing hair shaft disorders and the potential insights hair microscopy can provide, without reporting new clinical findings.

This article reviews various medical treatments for hidradenitis suppurativa based on the author's experience with over 350 patients, but it reports no new clinical findings.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This review emphasizes that collaboration between forensic anthropology and molecular anthropology could significantly improve the identification of unknown human remains by creating more comprehensive biological profiles.

This chapter describes two simple, noninvasive methods — the pull test and modified wash test — which can diagnose and assess the severity of female hair loss, including conditions like telogen effluvium and androgenetic alopecia.

This study found that both epithelial and hair keratins are expressed in beard hair medulla cells, exhibiting unique patterns and interactions distinct from other hair follicle and epithelial cells.

In this proteomic analysis, the researchers found that transitioning from crimped to straight wool in Tan sheep is linked to significant changes in wool protein expression, revealing distinct patterns of keratins and keratin-associated proteins that could influence wool quality and economic value.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

This study found that keratin 15 lacks the ability to sequester YAP1 in keratinocytes effectively, unlike keratin 14, and suggests that a higher K15:K14 ratio may promote a progenitor state and inhibit differentiation in epidermal keratinocytes.

This study found that in Arabidopsis thaliana, the interaction between extracellular leucine-rich repeat extensins and the receptor-like kinase FERONIA helps control vacuolar expansion, crucial for cellular elongation.

This study found that non-ablative fractional erbium glass laser treatment affected gene regulation in human skin models by downregulating MMP and interleukin expression, suggesting potential roles in dermal remodeling and anti-inflammatory effects.

This study describes the anatomy of arrector pili muscles in scalp hair follicular units, proposing a model where a single muscle structure is shared by all follicles within a unit.
