This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This review discusses surgical factors that may increase the risk of developing complex regional pain syndrome and describes potential preventive techniques but presents no new clinical results.

In this study, a newly developed nanoparticle-loaded hydrogel wound dressing demonstrated significant antibacterial, antioxidant, anti-inflammatory, and proangiogenic activities, effectively reducing pain and promoting healing in a murine burn wound model while preventing infection by *Staphylococcus aureus*.

This review examines the diverse roles of SRD5α enzymes across species, focusing on their involvement in steroid synthesis, sexual development, and various physiological processes, but reports no new clinical results.

In this study, researchers found that washing hair 5–6 times per week results in higher satisfaction and better objective and subjective hair and scalp conditions among Asian populations, with no observed detrimental effects from frequent washing.

This study concluded that the GIANT brain atlas, which integrates genetic and neuroanatomical variations, provides a more accurate representation of brain structure than traditional neuroanatomical atlases, allowing for better exploration of genetic influences on the brain.

In this rare case report, the researchers described a 66-year-old African woman with lipedematous alopecia, highlighting its clinical features, the significance of palpation in examinations, and the uncertainty of it being a distinct disease entity or a combination of two conditions.

This study suggests that Keratin 6hf may be a potential marker of oral squamous cell carcinoma and could play a role in its progression, though further research is needed to understand its function.

In this observational study, hair density was found to vary with age, as measured in subjects from a dermatology outpatient department, with males showing a mean unit density of 104.78 and females 108.36.

This study investigated the dynamic mechanical properties of fluid-immersed elastic hair beds under oscillatory shear flows, revealing a nonlinear response influenced by driving frequency and amplitude, which impacts mechanosensory signaling stability in biological processes like vasodilation and ciliary remodeling.

This study revealed that during avian skin development, complex tissue architecture results from specific cellular flows and mechanical processes that guide feather bud protrusion and elongation, with distinct differences noted in scale development, where rigidity restricts such transformations.

In this study, the researchers reported that a newly developed PYGL inhibitor, HTPI, enhanced hair growth in an ex-vivo culture by reducing oxidative damage in hDPCs and inhibiting glycogen degradation in hORSCs, showing potential as a treatment for hair loss comparable to minoxidil.

This review reported that the dwarf palm (Chamaerops humilis) is traditionally used in North Africa for treating diabetes and gastrointestinal diseases, and identified a need for more research on its pharmacological and ethnobotanical properties, particularly in relation to its potential cancer-fighting uses.

This abstract provides no study findings; it outlines website features and permissions for accessing JAMA Network content.

This study found that overexpressing the PCaP2 protein in Arabidopsis enhanced drought tolerance by influencing ABA and SA signaling pathways and regulating root hair growth, suggesting a key role in water deficit response.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

This study developed the Alopecia Areata Patient Priority Outcome (AAPPO), a new tool designed to measure and capture the symptoms and impacts of alopecia areata that matter most to patients.

This study found that p2y5 functions as a novel LPA receptor involved in the G13-Rho signaling pathway, with implications for human hair growth, and proposes renaming it to LPA6.

The enzyme PA-PLA1α is important for proper hair follicle development.

This study found that the Alopecia Areata Patient Priority Outcomes questionnaire is a reliable and valid tool for measuring the severity and impact of hair loss in individuals with alopecia areata.

A specific mutation in PA-PLA1α causes abnormal hair growth.

In an outpatient cardiology center, this study found that introducing the AHA/ACC ABI screening protocol significantly increased the frequency of ABI ordering by 31.6% for symptomatic patients.

This review discusses the pathophysiologic role of lysophosphatidic acid in the skin and reports no clinical results, suggesting pharmacological inhibition as a potential treatment for various skin disorders.

In this study, PA-011, a traditional Chinese medicine extract, was shown to improve hair growth in alopecia areata model mice by reducing skin inflammation and altering skin microbiota, indicating its potential therapeutic role for this condition.

This review evaluates the role of the nuclear receptor PPAR- in skin diseases, highlighting its regulation of inflammation, lipid metabolism, and immune response, and suggests that PPAR-agonists could be promising therapies for conditions like psoriasis and atopic dermatitis.

In this study, UPA at doses of 15 mg and 30 mg showed higher efficacy than placebo for treating severe alopecia areata in adults and adolescents over 24 weeks, with a safety profile similar to approved uses.

In this study, PA-011 extract was reported to promote hair growth and alleviate alopecia areata symptoms in mice by reducing skin inflammation and modulating skin microbiota.

This case report highlights a rare instance of diffuse alveolar hemorrhage in a patient with catastrophic antiphospholipid syndrome, emphasizing the importance of early recognition and multidisciplinary management.

This review discusses newly identified non-Edg family lysophosphatidic acid receptors, detailing their roles in vascular development, platelet activation, and hair growth, and reports no clinical results.

This study found that PPARα agonists provided protective effects in mouse models of alopecia areata by promoting early reversal of the condition and inhibiting T effector cell function, indicating potential therapeutic value for this inflammatory condition.
