This genetic study identified four new keratin-associated protein genes in sheep, revealing significant sequence variation and suggesting complex evolutionary dynamics, with unique variants in some sheep breeds linking them to Romanov sheep ancestry.

This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.

This review discusses the complex causal relationships between testosterone exposure and various health outcomes, but notes that the studies reviewed show substantial heterogeneity.

This review provides an overview of skin manifestations associated with substance use disorder but reports no new clinical findings; the authors emphasize the importance of dermatological evaluation and multidisciplinary care in managing these cases.

This study analyzed proteomic changes in Jiangnan cashmere goats' secondary hair follicles and found that the PLIN2 gene significantly impacts hair follicle growth cycles by affecting dermal papilla cell proliferation, offering insights into breeding strategies to enhance cashmere yield.

In this study, repetitive subcutaneous administrations of a conditioned medium from stem cells significantly suppressed hair graying in mice exposed to X-ray irradiation, likely through antioxidative mechanisms involving HGF and potentially VEGF.

This review highlights the multifaceted roles of hair follicles in skin health, emphasizing their contribution to skin tumorigenesis, homeostasis, and wound healing, and how dysregulation in associated pathways like Wnt, Hedgehog, and Notch may contribute to skin cancer development.

In this review, the authors discuss how hair may protect against scalp skin cancer by enabling IL-17-biased immunosurveillance, while hair loss could permit tumor development by reducing this immune protection.

This review by two dermatologists suggests that hair on the human scalp may protect against skin cancer not just physically, but by enabling IL-17 immune surveillance, with hair loss potentially leading to increased tumor growth due to reduced immunosurveillance.

In this review, the authors propose that hair on the scalp may protect against non-melanoma skin cancer by maintaining an IL-17 biased immunosurveillance, with hair loss potentially increasing the risk of skin cancer due to disrupted immune monitoring.

In this study on Angora rabbits, researchers identified genetic factors influencing wool fiber diameter by analyzing hair follicle proteins, highlighting keratin family members and other proteins as key contributors to fiber differences between coarse and fine wool.

In this study, researchers analyzed the skin proteome of Alpine Merino sheep to identify proteins and pathways related to wool fiber diameter, finding that cyclic adenosine monophosphate and certain signaling pathways may play a role in this trait.

This study identified a primitive coarse wool characteristic in Merino sheep that enhances environmental adaptability and fine wool yield without reducing quality, suggesting that epigenetic mechanisms, particularly involving the imprinted Gtl2-miRNAs locus, regulate this advantageous trait.

This study found that the ashwagandha extracts ASH-Ext1 and ASH-Ext2 show different pharmacological activities in cell models due to their distinct withanolide proportions, highlighting the need for standardized extraction protocols to ensure consistent therapeutic efficacy.

In this study, researchers found that melanoma risk factors and characteristics vary with age, noting distinct differences in younger, middle-aged, and older patients, with strong correlations in the oldest group.

This article reviews the cutaneous side effects of immune checkpoint inhibitors and targeted therapies for skin cancers, noting that while generally mild, these effects can influence treatment decisions and quality of life, underscoring the need for physicians to be aware of these adverse reactions.

This study identified several drugs that may be potential candidates for repurposing as anti-hyperhidrosis treatments, based on their association with hypohidrosis or anhidrosis in the FDA Adverse Event Reporting System.

This study reported detailed three-dimensional ultrastructural observations of human hair and hair follicles using a modified preparation method, including morphological differences in hair bulb cell layers and surface projections on root sheath cells.

This abstract reports no new research findings; it includes an educational image of microorganisms found in a skin biopsy.

This study found that a new SIS-PEG sponge promoted rapid skin defect healing in mice and showed potential for reconstructing reconstituted skin with regenerated hair.

This study found that 90% of African pygmy hedgehogs at Golden Dhonje Farm in Bogor District were affected by potential zoonotic fungi, including Scopulariopsis sp. and Penicillium sp.

This case study reports a peculiar variant of an epidermal cyst in a patient, featuring unique characteristics like brownish, lumpy contents resembling bone marrow.

This study found that a new 3D image analysis method from SEM images enables quick and accurate measurement of cuticle scale heights in hair fibers.

This study demonstrates that a 3D-printed agarose microwell platform supports the growth of size-uniform, viable NSCLC cancer spheroids, and can effectively evaluate drug responses using limited tumor material from biopsies, particularly with EGFR tyrosine kinase inhibitors gefitinib and osimertinib.

This study observed that bacterial communities on scalp hair collected through non-invasive swabbing showed similar diversity and composition to those obtained by cutting or removing hair, suggesting that swabbing is an effective method for microbiome analysis on hair.

This study reported that mSKPs and DMSCs share similarities in biological characteristics but exhibit distinct transcriptome profiles, with mSKPs being more immune-related and DMSCs more associated with differentiation and disease pathways.

This case report describes a severe Sarcoptes scabiei infestation in a stray FIV-positive cat, which typically is a non-permissive host for the mite, leading to considerable clinical recovery after treatment.

This study used Scanning Electron Microscopy to analyze South American mummy hair, revealing high levels of sulfur, calcium, and potassium, highlighting SEM's utility in anthropological investigations.

This study identified a new Demodex species causing demodicosis in a zoo koala, successfully treated with daily oral ivermectin.
