This study indicates that sheep prenatally androgenized with testosterone show wool fiber diameter changes that parallel the increased hair diameter in women with polycystic ovary syndrome.

This study found that β-catenin stabilization in specific mammary epithelial lineages leads to cellular changes and the formation of hyperplastic lesions, revealing its role in initiating mammary neoplastic development.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This study found that overexpression of activin in transgenic mice led to enhanced granulation tissue formation after skin injury due to changes in keratinocyte proliferation and differentiation.

In this study, BLIMP1 was found to function in terminally differentiated epidermal cells to maintain homeostasis, rather than defining a sebocyte progenitor population.

This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

This study found that a mixture of plant extracts significantly improved skin barrier function, reduced inflammation, and exhibited anti-aging effects in human skin cells.

This study demonstrated that treating platelet-rich plasma with ozone or procaine in vitro led to distinct changes in platelet activity, significantly enhancing the release of platelet-derived factors without damaging the platelets, indicating potential for improved regenerative therapies.

In this study, flutamide at therapeutic doses caused significant histological changes in the testes and epididymis of adult albino rats, reducing androgen receptor immunoreactivity and increasing estrogen receptor immunoreactivity.

This review detailed the types and mechanisms of injectable "skin boosters" and evaluated their effectiveness and safety for mitigating age-related skin changes, providing insight into their use in contemporary dermatological practice.

This study reports that transgene insertion in homozygous transgenic mice causes irreversible hair loss and impaired immune function, linked to interruption of the hairless locus on Chromosome 14.

This study found that a combination of photoprotector and nighttime formulations with essential oils improved skin barrier function and structural characteristics in young men's oily, acne-prone, and photoaged skin.

This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

This study reports that during late embryogenesis and early postnatal development, K79-expressing keratinocytes change and die independently of sebaceous glands to form the hair follicle opening, potentially influencing conditions like ingrown hairs or acne.

This study observed significant clinical effects, such as hair loss and testicular changes, in common quail treated with the steroids IVF-C Inj and Diane-35, especially highlighting cyproterone acetate's impact on vital organs like the liver.

This review discusses the relationship between insulin regulation and hyperandrogenemia in polycystic ovary syndrome, suggesting potential benefits of insulin-lowering treatments for ovarian function but reporting no definitive results for hair-related symptoms.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

This review discusses the presence of the StAR protein in 17 non-classical steroidogenic tissues, suggesting that advanced detection methods are needed for a complete understanding of its functions in these tissues.

This overview examines the biology, origin, structure, and function of various cells and structures, such as the blood-retinal barrier and Merkel cells, and discusses their roles in disease pathogenesis, along with recent findings related to the lymph nodes' paracortex.

In this case study, a 20-year-old female with hypothyroidism experienced marked symptom improvement, including weight reduction and menstrual regularization, after Ayurvedic management involving herbal remedies and lifestyle changes, suggesting Ayurveda could complement conventional therapies and indicating the need for larger-scale validation.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

This study found that mice lacking the 1αOHase enzyme, which is responsible for producing a key vitamin D metabolite, showed impaired epidermal differentiation and delayed recovery of skin barrier function after disruption.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This review discusses the mechanisms governing epidermal stem and progenitor cell differentiation, emphasizing the balance necessary for maintaining skin barrier function, and reports no new experimental findings.

This study examined variations in epidermal thickness and protein expression across different dog breeds, finding significant differences by anatomical site and breed, with associated mRNA and protein expression changes observed.

This study found that skin surface lipids contain measurable mRNAs, providing a non-invasive way to study skin diseases, with specific gene expression changes observed in atopic dermatitis patients.

This review explores the complex role of the Innate Immune System in rheumatoid arthritis, highlighting gaps in understanding its functions and interactions with the Adaptive Immune System, offering insights into potential biomarkers and therapeutic strategies for this challenging autoimmune condition.

This chapter reviews the presence and roles of stem cells in various body systems, focusing on their lifelong function in animals and humans, and reports no new experimental findings.
