This article reviews the complex pathophysiology of polycystic ovary syndrome, highlighting how genetic, hormonal, and environmental factors contribute to its diverse symptoms, and reports no new results.

This article reviews the roles of lesser-known secreted phospholipase A2 isoforms in various biological processes, such as immune suppression, metabolic regulation, epidermal hyperplasia, and male reproduction, without reporting new clinical findings.

This study reports that patients with specific MFN2 mutations, including p.Arg707Trp, exhibit significant upper body fat overgrowth with suppressed leptin production, suggesting tissue-selective mitochondrial dysfunction and potential therapeutic targets.

This study suggests that specific mutations in the MFN2 gene, including the p.Arg707Trp allele, can result in tissue-selective mitochondrial dysfunction leading to excessive upper body fat growth and low leptin levels.

This case report describes a novel association between uncombable hair syndrome and Zellweger syndrome due to a homozygous mutation in the PEX12 gene.

This case study reports a previously undescribed cause of drug-induced autoimmune hepatitis triggered by para-aminobenzoic acid (PABA), emphasizing the need for caution with this supplement.

The study concluded that fatty acid transport protein 4 in epidermal keratinocytes is crucial for maintaining normal skin structure, as its deficiency led to hyperkeratosis and epidermal barrier disruption in mice.

This study found that vitamin D supplementation in diets of Rex rabbits improved hair follicle development and fatty acid metabolism, with 1400–2100 IU/kg proving most effective for hair density and 2800 IU/kg increasing hair length.

This Special Issue in Nutrients investigates the nutritional strategies and outcomes in managing severe anorexia nervosa, with the aim of improving clinical practices for patients with serious or common physical conditions associated with the disease.

This study found that Peperomia pellucida, a plant traditionally consumed in some countries, contains various antioxidants and extends lifespan under oxidative stress in Drosophila, with no observed toxicity in mice, supporting its potential safety and use in foods and pharmaceuticals.

This study found that Lymphotoxin-beta primarily influences periderm differentiation, impacting epidermal and hair follicle differentiation at later stages.

This review discusses post-acute sequelae of SARS-CoV-2 infection, highlighting the challenges in diagnosing and managing the variety of persistent symptoms, and reports no new clinical results.

The researchers reported that autophagy, a lysosome-dependent degradation mechanism, plays a significant role in the cellular remodeling of keratinocyte differentiation in the skin, affecting the properties of the differentiation products by altering cellular components during this process.

This study found that keratin damage in mammals and birds can result from N-homocysteinylation, reducing keratin solubility and indicating significant protein modification through genetic or nutritional disruptions in homocysteine metabolism.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

This study found that low serum testosterone and elevated serum oestrone in men with cirrhosis are associated with worse liver disease and adverse health outcomes, suggesting oestrone as a potential ill health marker.

This study found that a 6-month treatment with either metformin or rosiglitazone significantly improved endothelial function in young women with PCOS without any one drug being superior.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study evaluated potential penile vascular changes and persistent adverse effects in men discontinuing 5α-reductase inhibitors for androgenic alopecia, but no new clinical results were reported.

In this study, researchers found a significant prevalence of nonalcoholic fatty liver disease in Egyptian women with polycystic ovary syndrome, with insulin resistance being a key predictive factor.

This review details the expression and diverse functions of melatonin receptors in non-neural tissues and reports no new clinical findings, emphasizing their potential as therapeutic targets across various physiological and pathological processes.

This review summarizes recent multidisciplinary advances in sebaceous gland research and highlights potential novel therapeutic strategies for skin diseases, but it reports no new clinical results.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study found that transgenic mice expressing human keratin K8 in the epidermis showed increased progression of skin lesions toward malignancy, suggesting a role for K8 in the development of invasive skin cancer.

This narrative discusses the critical roles of zinc in both biological processes and industrial applications but provides no new research findings.

Liver transplant can lead to neurological, pulmonary, cardiovascular, and renal complications, with older patients facing higher risks.

This chapter explores the potential of phytochemicals in modulating human endocrine function, emphasizing the growing interest in plant-derived alternatives to synthetic medications for managing metabolic and hormonal disorders often linked to chemical exposures and lifestyle factors.

Oxygen levels can drop during liver transplant if bypass pressures are too high, but other reasons should be checked first.

This study found that women with polycystic ovary syndrome have a higher prevalence of non-alcoholic fatty liver disease and increased androgen bioavailability may be involved alongside metabolic factors.

This case report describes a patient with various conditions, including ulcerative colitis and azathioprine-induced liver injury, and reviews related literature on these coexisting conditions.
