This paper reviews the diagnostic criteria, associated morbidities, and possible evolutionary advantages of polycystic ovary syndrome, but does not report any new findings.

This study utilized a sequence-structure alignment approach to improve the characterization of Class A Rhodopsin GPCR superfamily, including orphan and unclassified receptors, through evolutionary analysis.

This review summarizes recent advances in nanomedicine-based therapies for psoriasis, highlighting their potential to provide targeted and sustained therapeutic effects by modulating key cellular components and signaling pathways involved in the disease, offering novel perspectives for future treatment development.

This review discusses the evolutionary history of keratins and reports no new results, highlighting key events that contributed to the development of mammalian hair and integument.

This study examined the evolutionary and functional homology of steroid 5α-reductase and DET2 proteins, identifying protists as a common ancestor, and discovered a new subclass DET2-like in plants, potentially involved in polyprenol reduction.

This review highlights new perspectives in genomics and epigenomics for skin rejuvenation, comparing innovative strategies like senolytics and DNA repair modulators with classical treatments, and emphasizing the importance of tailoring therapies using individual genomic profiles for personalized anti-ageing approaches.

This study highlights the role of innate immunity and purinergic signaling in regulating hematopoiesis and hematopoietic stem/progenitor cell specification. The researchers observed that these ancient pathways operate both paracrinally and autocrinally within HSPCs, maintaining their developmental function throughout evolution.

This review discusses the various aspects of insulin resistance and highlights its potential evolutionary benefits, reporting no new experimental findings.

This review examines how genetic variants associated with polycystic ovary syndrome affect reproductive success differently in men and women, supporting the theory that intralocus sexual conflict may explain its persistence.

This review explores the historical development of theories on physiological tissue regeneration, particularly focusing on peripheral nerve regeneration, and emphasizes the need for new experiments and perspectives without providing new empirical findings.

This review explores the emotional and psychoanalytic significance of male pattern hair loss through four perspectives but reports no new clinical findings.

This review provides an overview of Hox genes, focusing on their evolutionary history, genomic organization, and roles in development, but reports no new study results.

Forensic medicine is crucial for justice and needs continuous innovation and technology integration.

In this study, researchers performed a genome-wide characterization of the Wnt gene family in domestic donkeys, identifying 19 genes and highlighting their evolutionary conservation among mammals, along with tissue-specific expression patterns potentially linked to reproductive regulation and tissue homeostasis.

This study proposes that the ability of humans to grow long scalp hair is linked to the evolutionary adjustment of molecular checkpoints that regulate the hair growth cycle, potentially influenced by its roles in communicating age, maturity, and social signals.

This article discusses various aspects of hair and scalp health, ancient philosophical perspectives on hair, and causes of hair disorders in children, without reporting new clinical results.

This article proposes a hypothesis that KRT75, a protein found in hair follicles, was evolutionarily co-opted by ameloblasts during the development of prismatic enamel in synapsids, but reports no new results.

This review argues that the immunocompetence hypothesis, linking masculine facial features to attractiveness through health benefits, lacks sufficient evidence and sidesteps alternative explanations.

Understanding where cancer cells come from helps create better prevention and treatment methods.

Humans lost body hair relatively recently in evolution.

This editorial discusses the biology and pathology of hair follicles, including factors like fungi and hair loss therapies, but provides no new research findings.

This study found that humans have a significantly slower wound-healing rate compared to non-human primates and other animals, suggesting that slow wound healing is a characteristic unique to humans within the primate order and potentially indicating evolutionary adaptations.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

This article discusses the hypothesis that mechanisms driving androgenic alopecia may reduce the risk and proliferation of prostate cancer by increasing prostaglandin D2 levels but presents no new clinical findings.

In this study, whole-genome sequencing of Lanping black-boned sheep identified ERBB4 and ROR1 genes as potentially important in their distinctive hyperpigmentation, enhancing understanding of their genetic evolution from Lanping normal sheep.

This paper discusses how Bram Stoker's "The Secret of the Growing Gold" reinterprets a Hungarian folktale to reflect British Victorian racial anxieties, linking Teutonic superiority with Hungarian folklore.

This study suggests that the keratins found in reptile and bird skin appendages evolved independently from mammalian hair keratins, highlighting convergent evolution in these species.

This study identified distinct gene expression programs in keratinocytes responsible for forming hard scales and soft interscale epidermis in chickens, revealing conserved differentiation genes similar to those in human skin.

This essay reviews the role of human scalp hair follicles in the "brain-skin connection," highlighting their dual function as targets and sources of neurohormones, without reporting new experimental results.

This article discusses how the brain's neural circuits evaluate skin aging to judge social standing and suggests that people often attempt to deceive themselves and others about their true age.
