This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

This study found that the Meibomian gland shares structural and cytokeratin composition similarities with hair follicles, and plays a role in hyper-keratinisation observed in obstructive Meibomian gland dysfunction.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

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 article reviews the roles and synthesis of essential long-chain fatty acids in the body and reports no new research findings; it emphasizes the importance of dietary sources for these lipids.

This study reported that the coat hairs of golden takin, living in harsh environments, have unique structural features compared to cattle, with overcoat hairs having continuous medullated tissue and undercoat hairs being finely crimped, potentially contributing to temperature regulation in cold conditions.

This review discusses theories and treatments for body image disturbances and reports no new clinical results.

This study describes unique anatomical characteristics of the skin and hair structures in the silver marmoset, including features such as thin epidermis, specialized nerve end-organs, and distinctive gland compositions.

This study found no significant histologic differences in skin structure based on age, sex, or woodchuck hepatitis virus infection status among woodchucks.

The article concludes that products can affect the body without being drugs as long as they don't claim to treat or prevent diseases, except for cosmetic sunscreens.

This article reviews the various functions of the skin, its structure, and the impact that damage or disorders can have on both skin function and interpersonal communication, without presenting new experimental findings.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

This review highlights that biomaterial properties can be designed to modulate macrophage activity, potentially reducing foreign body responses and enhancing tissue healing in regenerative medicine.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This paper proposes a theory explaining how the normal anabolic effects of androgens lead to structural changes and hair follicle miniaturization, contributing to androgenic alopecia.

This research outlines an innovative bioregeneration chamber aimed at significantly extending human lifespan and enhancing health maintenance by treating the body as a thermodynamic system, potentially enabling an average lifespan of 130 to 150 years in an advanced therapeutic setting.

This chapter emphasizes the critical role of the integumentary system in animal physiology, detailing its structures, immune functions, and sensory capabilities as crucial for homeostasis, protection, and various physiological processes.

This study found that a high-fat diet in rats led to obesity, insulin resistance, and structural changes in the parotid salivary glands, with associated negative impacts on general health.

This study found that skin thickness in Bakerwali goats increased with age, with notable histological differences in these layers across diverse regions of the body.

This review highlights the potential of microneedles as a pediatric-friendly method for delivering proteins, vaccines, and diagnostics transdermally, noting their ability to penetrate the skin's barrier and suggesting future applications in other parts of the body.

This study used whole-genome resequencing to analyze genetic diversity and selection in 17 rabbit breeds, identifying genes linked to traits like coat color and body size, which could inform breeding and conservation efforts.

This case study describes a 54-year-old woman with a rare pattern of asymmetrical hair loss resembling androgenetic alopecia, alongside sparse body hair and near absence of eyebrows and eyelashes, while other ectodermal features were normal.

This article reviews the use of hair analysis in forensic and environmental toxicology for detecting potentially toxic elements and drugs, but it reports no new research findings.

This article describes the development and growth stages of hair follicles during intrauterine life and subsequent growth phases on the scalp but reports no new clinical results.

This chapter discusses various aspects of collagen, proposing "extended collagen carential disease" as a new concept tied to nutritional deficiencies, notably Vitamin C's role in maintaining collagen health.

This review discusses the potential of Pluronic F127-derived hydrogels for wound healing, examining their applications in various wound types and exploring underlying mechanisms and their interaction within the wound microenvironment.

This case study describes a 40-year-old man diagnosed with pilotropic mycosis fungoides, a form of folliculotropic cutaneous T-cell lymphoma, characterized by lymphocytic infiltration of hair follicles and eccrine glands.

This article discusses dermatologic adverse events associated with topoisomerase inhibitors and anthracyclines, such as alopecia and hand-foot syndrome, but reports no new clinical results.

This review discusses caffeine's biological activities relevant to cosmetics, such as antioxidant effects and potential benefits for hair growth, but reports no clinical results; the safety considerations are addressed.
