In this study, researchers observed that graded calorie restriction in mice led to changes in stable isotope ratios and elemental content in bone collagen and hair keratin, potentially indicating intensified mobilization of endogenous proteins and altered bone collagen structure with increased dietary stress.

This study developed the mTurquoise2-Col4a1 mouse model and used fluorescent tagging of collagen IV to offer new insights into basement membrane dynamics during hair follicle budding, revealing that basement membranes are flexible and stable structures in developing skin tissue.

This study found that the newly developed transdermal oil body microgel emulsion (OBEME) improved wound healing in mice by enhancing skin permeability, reducing inflammation, and promoting new blood vessel formation and re-epithelialization.

This study found that long-term hair follicle stem cells originate from embryonic progenitor cells in a niche with reduced Wnt/β-catenin signaling, which is essential for their specification.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.

This article reviews the relationship between the skin and the immune system and discusses how skin manifestations can indicate immunodeficiencies but reports no new research findings.

This study found that distinct low-threshold mechanoreceptors innervate different hair follicle types in mice, suggesting that these follicles serve as unique mechanosensory structures in touch perception.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

In this study, researchers achieved complete reepithelialization and hair growth on a burn-injured scalp using a tissue-engineered dermal template with early micrograft hair follicle implantation.

The study found that melatonin treatment in early postnatal cashmere goats increased both the quantity and quality of cashmere by promoting secondary hair follicle development and enhancing antioxidant enzyme activities.

This study reports that biomass activated carbon fibers derived from metaplexis japonica seed hair effectively adsorb methylene blue dye, demonstrating high capacity and rapid adsorption performance.

This review discusses the current state of research on skin organoids, highlighting their potential for replicating complex skin structures and comparing recent studies on stem cell microenvironments.

This study reported that human induced pluripotent stem cell-derived skin organoids, used to model epidermolysis bullosa, have an epidermal-dermal junction largely lacking type VII collagen, which is important for skin structure.

This classification proposal introduces a novel system for categorizing cutaneous adnexal cysts based on their origin in the folliculosebaceous unit and sweat glands, aiming to simplify and enhance understanding of these skin lesions.

This study presents a modified method for synthesizing ~1 nm zinc oxide nanoparticles within the pores of SBA-11, maintaining the mesoporous structure without requiring alcohol reflux or basic solution reaction steps.

This study revealed that BMP5 in onychofibroblasts may play a key role in the differentiation of nail matrix keratinocytes, highlighting transcriptional similarities between nail and hair structures.

This review discusses historical and recent advances in understanding the embryonic organizer's role in patterning during development, including molecular pathways and future research challenges, but reports no new experimental data.

This study found that in Arabidopsis root hairs, oscillating cytoplasmic potassium dynamics precede growth oscillations, suggesting a complex interplay with calcium signaling and microfilament structure in regulating root hair growth.

This review examines physical methods like electron paramagnetic resonance spectroscopy, Raman spectroscopy, and differential scanning calorimetry, highlighting their complementary capabilities in analyzing biomolecular structures and mycobacterial interactions with reactive oxygen species and antioxidants.

This article reviews the commonality of androgenic alopecia in men over 30 and the use of finasteride, without reporting new research findings.

This review provides an overview of composite scaffold materials for skin that mimic natural dermal tissue, and highlights their potential in treating chronic wounds like diabetic foot by promoting cellular growth.

This chapter discusses the role of hormones in regulating reproductive biology and outlines how the endocrine system, particularly the brain and pituitary gland, controls these hormonal processes.

This study found that a five-dimensional model of personality perception from men's facial photographs better captures the complexity of face perception than the traditional two-dimensional Valence-Dominance model, highlighting overlaps with personality structures known from differential psychology.

This source highlights that while plant sterols show potential benefits and applications in various industries, significant research gaps, including their complex structures and mechanisms, hinder their broader use, emphasizing the need for innovative sources and sustainable methods for their study.

Hormone therapy is safe and effective for transgender adults, but requires regular monitoring and mental health support.

Hormones, especially androgens, play a key role in causing acne, and treatments like hormone control pills and hormone-blocking medications can help.

This study used an ex vivo human skin model to show that tropical conditions disrupt skin homeostasis, resulting in epidermal thickening and junctional flattening, and found that Kombucha tea extract may help preserve skin structure under such stress.

This study reported that discarded squid ink was used to develop a high-performance, environmentally friendly hair dye that offers a stable deep black color, UV protection, and preserves hair structure, while showing excellent biosafety in lab tests.

This study found that the prenatal skin development in Red Sokoto goats undergoes significant morphological changes across gestational stages, which may be important for their adaptation and thermoregulation after birth.

This review discusses the use of experimental animal models to better understand the poorly understood mechanisms behind polycystic ovarian syndrome and reports no new clinical results.
