Runx1 is crucial for proper hair structure and development.

This study found that α-MSH administration before skin wounding in adult mice reduced inflammation and scar area, suggesting a potential pathway to more regenerative healing.

This review investigates laser-induced Koebner-related reactions and highlights how different laser types, targets, and session frequencies affect the development of these skin responses, particularly in individuals with darker skin phototypes.

This study demonstrated that intraoperative bioprinting using a bioink with human adipose-derived extracellular matrix and stem cells achieved successful reconstruction of full-thickness craniomaxillofacial skin defects in rats, promoting wound closure, adipogenesis, and hair follicle-like structure formation within two weeks.

This study observed that using an environmentally friendly bovine milk permeate effectively and cleanly removes wool from sheepskins without harming the skin, and results in smoother leather compared to traditional chemical methods.

This review considers oxidative stress effects on hair aging and emphasizes the need for dermatologists to recognize and treat factors affecting scalp and hair health, but it provides no new clinical findings.

This article discusses a wide range of procedures in facial plastic surgery and highlights the recent advancements and trends without reporting new clinical findings.

This review discusses the pathophysiology, diagnosis, and treatment of polycystic ovary syndrome, emphasizing the critical importance of early diagnosis and treatment to prevent metabolic complications and improve quality of life.

This article discusses a potential link between adipocyte-myofibroblast transition and androgenetic alopecia, suggesting AMT may play a role in fibrosis associated with the condition but presents no new results.

Platelet-rich plasma therapy helps improve atrophic acne scars.

This study found that using a plasma hairdryer for 90 minutes caused significantly less hair damage, such as cuticle cracks or layer separation, compared to traditional hot air dryers.

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 describes a new intravital microscopy method for observing intestinal regeneration by tracking crypt dynamics in living mice after laser-induced tissue damage, revealing events like crypt fission, fusion, and disappearance over multiple weeks.

In this study, treatment with fractional CO2 laser combined with recombinant humanized type III collagen led to significantly better improvements in atrophic acne scars compared to laser treatment with saline, attributed to collagen upregulation and MAPK pathway activation in human dermal fibroblasts.

This review discusses the biological and cosmetic aspects of hair aging and reports no new clinical results; it highlights current treatments and future research directions to address both aging factors.

This study demonstrated that using a mass spectrometry imaging technique, researchers were able to visualize the incorporation of argan, avocado, and coconut oils into hair fibers, suggesting their potential in cosmetic and alopecia treatments by confirming oil absorption and fiber modification.

This study's simulations suggest that biomechanical factors, like follicle geometry and tissue stiffness, are likely significant in hair fiber protrusion, providing a framework for future experimental validation.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This study found that phosphorylated VEGFR-2 is present in human scalp epidermal appendages and suggests it plays a role in their daily regulation.

In this review, the authors discussed how men seek cosmetic procedures for distinct reasons compared to women, emphasizing the need for dermatologists to consider male-specific desires for discrete treatments with minimal downtime and differences in psychological motivations.

The antidepressant escitalopram likely caused hair loss in a patient.

In a mouse model, this study found that exposure to PM2.5 leads to significant postpartum hair loss, apparent via morphological changes and elevated markers of inflammation, apoptosis, and fibrosis, potentially exacerbated by changes in hormone receptors and stem cell populations.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

This study examined the morphological features of buffalo lips, finding that their structure includes distinct layers of skin, muscle, connective tissue, and glands.

This study used social media data to identify more and milder COVID-19 symptoms than clinical research and to map symptom evolution over 27 months, highlighting differences between the Delta and Omicron periods.

In this study, researchers found that eccrine sweat glands in human scalp skin are morphologically integrated into the pilosebaceous unit, suggesting they form a common homeostatic tissue environment with adjacent structures.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.

This study investigated the hair of German shepherd dogs, revealing variations in color, shape, and band patterns across different body regions, while all hair types shared similar anatomical structures such as continuous, vacuolated medullas and cuticular scales with smooth or rippled margins.

This article discusses hair care practices and hair cosmetics in managing alopecia but reports no new clinical findings; it emphasizes the importance of scalp health and good patient-physician communication.
