In this study from Bangladesh Medical University, researchers found strong correlations between symptoms such as oligomenorrhea and amenorrhea with bilateral polycystic ovarian morphology in women with PCOS, highlighting the link between clinical symptoms and ultrasound findings in predicting the severity of the condition.

This study found that micro-computed tomography (micro-CT) was highly effective for analyzing the cross-sectional geometry of hair fibres, including the medulla in highly curled hair, but less effective than scanning electron microscopy for surface details.

This study analyzed the nanotribological properties of various hair types and human skin, revealing differences in friction and adhesion based on ethnicity and hair condition.

This review discusses the use of the human-on-mouse xenograft model for studying the human hair follicle cycle and emphasizes its utility for pharmacological testing, without reporting new clinical results.

This study concluded that including ovarian morphology in the diagnosis significantly increases the estimated prevalence of PCOS, revealing substantial variability due to clinical criteria and diagnostic cut-offs.

In this study, the researchers measured and discussed the friction and wear properties of various hair types against synthetic skin and other hair, finding variations based on factors like ethnicity, hair condition, and environmental conditions.

This study suggests that interfollicular epidermal keratinocytes with stem-like features may serve as an alternative to follicular keratinocytes for hair regeneration by supporting hair follicle morphogenesis in vivo.

This study found that the unique crest feather formation in Polish chickens is driven by a 195-bp duplication in the HoxC10 gene region, which alters gene expression by modifying the genomic structure, suggesting a mechanism for diverse integumentary appendages in birds.

This study in mice found that maternal iron deficiency led to hair loss and growth abnormalities in offspring due to increased oxidative stress and disrupted signaling pathways, but postnatal iron supplementation was able to reverse these effects.

In this study, XZYFD, a Traditional Chinese Medicine formulation, was found to improve androgenetic alopecia in a testosterone-induced mouse model by promoting hair regrowth, restoring follicular morphology, and modulating androgen metabolism, MAPK signaling, and lipid metabolism pathways, suggesting potential benefits for patients with metabolic dysfunction.

This study found that women with polycystic ovary syndrome showed significant differences in clinical symptoms, hormone levels, and ovarian morphology compared to healthy controls, such as higher body mass index, menstrual irregularities, elevated luteinizing hormone, and polycystic ovarian morphology, suggesting these factors enhance diagnostic accuracy.

This study found that male hairlines naturally exhibit significant rightward asymmetry, suggesting that embracing this asymmetry in hair transplant procedures may result in more natural-looking outcomes.

This article discusses the complex aetiology, diagnostic criteria, and challenges in diagnosing polycystic ovary syndrome, but does not report new clinical findings.

This review highlights the lack of research on Afro-textured hair, emphasizing the need for better understanding of its genetic traits and molecular structure to develop more effective hair care solutions.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This study suggests moving away from using rigid racial categorizations and outdated typologies in favor of analyzing detailed trait patterns, providing a foundation for future research on human variation and hair traits in relation to population affinity.

This study found that OR-101, a selective JAK3/TEK inhibitor, was associated with dose-dependent improvements in hair growth in humanized mice with alopecia areata, suggesting its potential as a treatment option.

This study found that the prevalence of PCOS among adolescent and young girls in India was 7.21%, with dysmenorrhea and acne being common symptoms.

This letter discusses a trichoscopic feature called the color-transition sign for differentiating between alopecia areata incognita and telogen effluvium, and reports no new clinical results.

This study observed that hair properties vary by ethnicity, influenced by genetic, environmental, and cultural factors, and noted that ethnicity-dependent differences in surface charge and other properties warrant further investigation.

This study reported that depleting the pro-apoptotic protein Bax in hair follicle stem cells enables these cells to kill nearby viable cells by sequestering TNFα, which increases the stem cell pool and accelerates tissue regeneration, suggesting potential implications for therapies targeting tissue repair and cancer.

This review discusses the clinical features and therapeutic goals for teenagers with PCOS, emphasizing the need for further research into its causes and potential long-term health risks, but reports no new clinical results.

This review examines the histopathologic features of four common types of noncicatricial alopecia and reports no new clinical results.

This study aimed to identify trichoscopic features that help differentiate between tinea capitis and alopecia areata in children, enhancing diagnosis and treatment decisions visually and non-invasively.

This review discusses the clinical features and treatment challenges of acne keloidalis nuchae, a form of chronic scarring folliculitis, and reports no new results.

This article reviews the clinical features, diagnostic criteria, and possible genetic and environmental influences of polycystic ovary syndrome but provides no new research findings.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

This review discusses the unique features of dermal white adipose tissue, its interaction with hair follicles, and its role in skin physiology, reporting no new experimental findings.

This article reviews the clinical and diagnostic features of hair shaft disorders, emphasizing the role of structured patient assessments and the avoidance of hair trauma, but reports no new results.

This study found that global PCOS prevalence in adolescents is 6.3% under new 2023 guideline criteria, compared to 9.8% using Rotterdam criteria; excluding PCOM may prevent over-diagnosis, while recognizing irregular cycles or hyperandrogenism helps avoid under-diagnosis by identifying at-risk individuals for further monitoring.
