Diazoxide, minoxidil sulphate, and cromakalim relax rat blood vessels by opening K+ channels, with some differences in their actions.

This study found that cellular retinoic acid-binding proteins and fatty acid-binding proteins are dynamically expressed in skin development and respond differently to retinoic acid, β-catenin, and Notch signaling.

Mutations in the DSG4 gene cause specific hair and scalp issues.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This study suggests that congenital atrichia with papular lesions may be more common than previously thought and proposes diagnostic criteria including the observation of hypopigmented whitish streaks on the scalp.

This study found that lower salmon availability was associated with higher stress hormone levels in grizzly and black bears, influencing their physiological responses and competitive behaviors.

This article reviews historical and recent developments related to toxic shock syndrome (TSS), emphasizing the increase in cases among young women using tampons, and calls for new research tools but does not report new results.

This study found that men receiving enzalutamide and other androgen-deprivation therapies may be at increased risk for QT prolongation and torsades de pointes.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

This study demonstrates that c-MYC overexpression in sebaceous glands affects differentiation via a regulatory axis involving the androgen receptor and p53, influencing carcinoma formation outcomes.

This study found that high-dose oral zinc significantly influences hair growth in mice, showing both inhibition and promotion effects depending on the timing and duration of administration.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

This review examines the role of steroidal inhibitors in treating prostatic diseases but presents no new clinical results.

This study found that MRL/MpJ mouse dorsal skin wounds heal with similar scar formation and collagen deposition as C57bl/6 and Balb/c mice.

This study analyzed skin from 538 knockout mouse mutants and identified 50 with epidermal phenotypes, providing valuable insights into genetic conditions and systemic effects related to skin abnormalities.

This study found that although progerin expression in mouse skin causes significant nuclear shape changes in keratinocytes, it does not result in alopecia or common skin abnormalities seen in human Hutchinson–Gilford progeria syndrome.

This review discusses the use of hair analysis for examining stress and reproduction hormone levels in wildlife and highlights the need for more comprehensive physiological validations across species.

This review highlights the need for a deeper understanding of 5alpha-reductases and neuroactive steroids to reduce potential adverse effects of 5alpha-reductase inhibitors used for conditions like benign prostatic hyperplasia and androgenic alopecia, but reports no new clinical results.

This study concluded that although RBP4 and adiponectin levels are associated with visceral fat, they do not independently contribute to the development of PCOS.

This study found that women with PCOS had lower fasting serum ghrelin levels and a reduced ghrelin response to an oral glucose load compared to controls, with an inverse relationship to insulin resistance.

This study found that full-length Agouti protein modulates melanocortin receptor signaling through a dual mechanism involving competitive antagonism and receptor down-regulation, whereas the carboxyl-terminal fragment acts solely as a competitive antagonist.

In this study, researchers observed that follicular microinflammation significantly contributes to the early stages of male androgenetic alopecia, potentially leading to perifollicular fibrosis and follicle destruction as the condition progresses.

This study demonstrated that tight junction barriers exist in human hair follicles but are less tight in hair follicle keratinocytes than in interfollicular keratinocytes, highlighting claudin-1's key role in follicle barrier function and growth.

This review discusses the biological roles and diagnostic significance of keratins in mammalian colon epithelial cells and reports no new clinical results.

This study found that berberine supplementation improved gut microbiota composition and reduced obesity-related hepatic inflammation and oxidative stress in genetically obese mice.

This review discusses the role of reactive oxygen species in regulating oscillating apoplastic pH gradients and growth in plant root hairs and pollen tubes, reporting no new experimental results.

This review discusses available microsurgical reconstructive options for craniofacial surgery and reports no new clinical results; it highlights how innovations in the field have advanced reconstruction techniques.

In this study, researchers found no hypertrophy in axillary sweat glands of hyperhidrotic patients, with eccrine gland clear cells being the primary site of fluid transport and no evidence of apoeccrine glands.

Food deprivation increases MST enzyme in the brain, possibly affecting energy balance.
