This case report highlights a rare presentation of acute lupus hemophagocytic syndrome with initially negative antinuclear antibodies, underscoring the higher sensitivity of the 2012 Systemic Lupus International Collaborating Clinics criteria for diagnosis.

This study concluded that neither basal nor ACTH-stimulated 17-OHP concentrations effectively indicate carrier status for 21-hydroxylase deficiency among Slovenian hyperandrogenic women, recommending molecular analysis of the CYP21 gene for reliable screening.

This study found that injecting hyaluronic acid fillers using a layered feathering technique temporarily corrected entropion and relieved associated symptoms in two dogs, an Old English Bulldog and a Chow Chow, maintaining eyelid positions for 6-8 months.

In this study, researchers found that stabilizing the protein HIF1A in hair follicles promotes glycolysis over oxidative phosphorylation, potentially reducing oxidative stress and supporting hair growth.

This study found that human hair keratin artificial tendons have low antigenity and may serve as an effective substitute for tendon repair in the upper extremities.

This study developed a handheld card to simplify the calculation of the SALT score for assessing alopecia areata severity, noting that while it accelerates the process, formal validation against existing methods is still needed.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

In this laboratory study, the researchers found that combining dermal papilla cell-derived exosomes with collagenous sequences significantly enhanced hair follicle stem cell migration and proliferation, highlighting a potential strategy for hair regeneration through modulation of the hsa-novel-238a-CASP9 axis.

This case report describes a father with HOXC13-associated pure hair-nail ectodermal dysplasia, presenting with severe nail dystrophy affecting all digits and notable hypotrichosis or complete alopecia.

This study found that SZ95 sebocytes and HaCaT keratinocytes exhibit distinct enzyme expressions and activities, implicating their different roles in androgen metabolism and homeostasis in vitro.

This study found that canine hair follicle stem cells in vitro expressed markers associated with multipotency, suggesting their potential role in the hair cycle.

HEV light can harm or help skin and scalp, so safe exposure guidelines are needed.

This study developed a herbal hair dye gel using natural ingredients like henna and amla, which was found to provide natural color, improve hair texture, and clean the scalp without causing irritation, making it a safe and effective alternative to chemical hair dyes.

High temperatures and certain chemicals can significantly change the amino acid content in human hair.

In this study, researchers found that the efflux of calcium in root hairs of Arabidopsis thaliana, particularly through the ER-localized ACA2 and ACA7, is crucial for modulating cytoplasmic calcium signals and enabling proper root hair growth, with disruptions leading to impaired elongation.

In this case series study, mild ovarian hyperstimulation syndrome was reported in only one out of 118 PCOS patients receiving highly purified HMG injections for IVF treatment.

This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.

The gene for Marie Unna hereditary hypotrichosis is located on chromosome 8p21, near the hairless gene.

This study found that the hair interior defect in AKR/J mice is linked to a mutation in the Soat1 gene, which disrupts SOAT1 protein expression and affects lipid metabolism critical for normal hair formation.

In a study on wound healing, researchers described injectable POEGMA‐DA hydrogels as a promising non-toxic alternative to traditional wound closure methods, showing effective tissue adhesion and enhanced regeneration of skin structures in a mouse model without significant inflammation.

New mutations in hair keratin genes cause the rare hair disorder monilethrix.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

This study found that double transgenic Arabidopsis plants overexpressing both AVP1 and AtNHX1 showed improved salt tolerance and enhanced root hair and hypocotyl growth compared to single transgenic lines.

This study found that in lamivudine-resistant hepatitis B patients, tenofovir significantly reduced HBV DNA levels faster and more consistently than adefovir, reaching undetectable levels in all treated patients by 44 weeks.

This study found that lentivirus-mediated overexpression of Sonic hedgehog significantly increased hair follicle stem cell proliferation and promoted hair follicle regeneration, with higher effects in non-alopecia areas.

This study found that human hair follicle-derived mesenchymal stem cells demonstrated enhanced wound healing capabilities compared to umbilical cord-derived stem cells in laboratory and animal models.
