This study found that a specific variant in hair keratin was present mainly in Caucasian samples, with few exceptions showing likely Caucasian admixture.

This study found that hCG decreased 5α-reductase and androgen receptor levels in skin samples from women in vitro, suggesting that human skin responds to LH/hCG treatment.

This article discusses the use of forensic DNA phenotyping to infer physical characteristics from biological samples without a reference sample, aiding investigations but raising ethical and legal concerns.

In this study, researchers found that storing hair samples for over 12 months significantly lowers the concentrations of important analytes such as cortisol and cortisone, recommending analyses within six months to ensure data quality.

In this study, transverse sectioning of scalp biopsy samples showed higher diagnostic accuracy than vertical sectioning for noncicatricial alopecia, although both techniques are important for accurate diagnosis.

This study confirmed that 25(OH)D3 can be detected in hair samples from healthy young adults, but no correlation was found between hair and serum 25(OH)D3 concentrations, indicating limited potential as a standalone biomarker.

The researchers reported that human hair keratin films exhibit color changes and reduced protein solubility after thermal treatments, suggesting their potential use in evaluating hair thermal damage instead of actual hair samples.

This study found that the presence of benzeneseleninic acid in commercial anhydride samples lowered the reaction rate during the oxidation of a finasteride intermediate compared to pure anhydride.

In this study, commercial synthetic braiding hair samples from Kenya were analyzed, revealing that while no Ammonium Thioglycolate was detected, significant formaldehyde contamination was present, with varying concentrations throughout the hair strands, potentially impacting consumer safety.

In this study, researchers analyzed over 5,000 T cells per sample using scRNA+TCR-seq technology and found that dual TCR Tregs are present in high proportions across various mouse tissues, showing unique TCR pairing patterns, V(D)J usage, and mRNA expression compared to single TCR Tregs.

The review suggests the study on male pattern baldness needs to improve in areas like sample size, methodology, and bias for better quality and credibility.

In this study, researchers analyzed skin samples from Dorper sheep to identify 395 differentially expressed long non-coding RNAs (lncRNAs) linked to hair follicle growth phases, suggesting these lncRNAs may play a role in the regulation of hair shedding through pathways like estrogen and PI3K-Akt signaling.

This study found no significant correlation between zinc deficiency and vitamin B12 levels in blood samples from Ahvaz residents, despite some observed age-related trends in micronutrient levels.

This study found that hair follicles and urine cell pellets from noninvasive samples may be the most promising for transcriptomic analyses due to their consistent quality and applicability to disease-relevant research.

This study evaluated the physicochemical properties of Neelibhringadi keratailam and found significant variations in market samples compared to a prepared sample, indicating potential quality control issues.

This study found that OCT4B1 isoform expression was elevated in tissue and blood samples from patients with inflammatory bowel disease, suggesting a potential role in tissue repair.

In this study, 30% of a diverse female sample reported experiencing what they perceived as excessive hair shedding, often beginning abruptly and without an attributable cause.

This study used one-dimensional SDS electrophoresis to examine low sulfur proteins in hair samples from multiple generations within five families, but does not report new results.

This review discusses the challenges of interpreting observational studies on COVID-19 due to biases from non-representative samples, such as collider bias, and suggests better sampling methods to mitigate these issues.

This research observed that multifocal pseudoepitheliomatous hyperplasia may explain some cases of squamous nests in vulvar lichen sclerosus with lichen simplex chronicus, potentially as a reaction to tissue damage rather than squamous cell carcinoma.

This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

Aδ-LTMRs have complex synapses with glycine, while Aβ-LTMRs have simpler ones.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This review examines non-invasive methods for diagnosing inflammatory skin diseases like lupus erythematosus and psoriatic inflammation using samples from plucked hair and skin tape-strips, but no new clinical results are presented.

This review discusses the clinical significance of L-Lysine in treating various conditions and reports mixed findings on its effectiveness against herpes simplex virus infections, with no new experimental results presented.

The researchers concluded that their new reconstructed human epidermis model from plucked hair follicle-derived keratinocytes offers a safer and simpler alternative to traditional skin-derived models for studying epidermal function.

This study found that brain-derived nerve factor protein expression was significantly increased in balding scalp samples from men with androgenetic alopecia, suggesting it may play a role in hair follicle regulation.

This study identified a moderately high prevalence of PCOS and significant associations with factors like hyperprolactinemia and menstrual irregularities in the sample, emphasizing the importance of awareness and early diagnosis to potentially reduce PCOS burden.

This discussion highlights the potential of next-generation sequencing in forensic science for predicting phenotypic traits from DNA samples, but reports no new clinical results and underscores ongoing ethical and legal challenges.

This study presents a case where telemedicine allowed for early detection of a dermatomyositis flare during the COVID-19 pandemic using simple patient-reported measures, despite challenges in remote assessment.
