This study found that faster algorithms for inferring ancestry in genomic data can better capture historical and functional insights into genome variation than traditional methods in large datasets like the UK Biobank.

This narrative review explores gender differences in the epidemiology, risk factors, and effects of COVID-19, emphasizing the need for further analysis using comprehensive gender indicators to shape effective public health strategies and policies.

This study found that Nubian ibex have developed genetic adaptations in response to their desert environment, including enhanced skin barrier, DNA repair, viral response, and metabolism of toxic compounds.

This review highlights recent advancements in understanding and treating alopecia, emphasizing genetic and immune factors involved in different forms, and discusses emerging therapies such as gene-editing and exosome-based treatments, though achieving complete hair regrowth remains a challenge.

This review discusses sex differences in immune responses to COVID-19 and highlights that males tend to experience more severe symptoms and higher mortality but reports no new clinical findings.

This article reviews gender differences in skin disorders, highlighting variations in disease prevalence and type between sexes, but reports no new findings, emphasizing potential implications for prevention and treatment strategies.

In this study, researchers observed that patients with androgenetic alopecia show differences in scalp microbial communities compared to the general population, including an increase in Cutibacterium acnes, particularly in males, which may interact with lipid and immune pathways to contribute to hair follicle miniaturization.

This article reviews the role of Pityrosporum (Malassezia) in skin conditions such as pityriasis versicolor, seborrheic dermatitis, and atopic dermatitis, and discusses treatment approaches; it reports no new clinical results.

This paper discusses the variability in COVID-19 susceptibility and severity, emphasizing factors like biological differences and suggesting potential precision medicine approaches, but it reports no new clinical results.

This review discusses genomic and postgenomic alterations in chronic degenerative diseases and potential modulation by dietary and pharmacological agents, reporting no new clinical results.

In this study, exotic lice were found to be widespread among mule deer in California, with younger age classes and low blood selenium concentrations being significantly associated with infestation.

This review discusses the molecular basis and clinical implications of primary generalized glucocorticoid resistance and hypersensitivity, attributing them to mutations in the human glucocorticoid receptor gene, and reports no new clinical findings.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

This study confirms the presence of large structural variations in the genome of Nellore cattle, which may contribute to their environmental adaptation to tropical regions.

This review discusses the host genetic factors influencing COVID-19 susceptibility and pathogenesis, highlighting genetic variations that affect viral entry and immune responses, but reports no new experimental results.

In this study, researchers analyzed 24 European Merino sheep populations to investigate genetic adaptations to climate, identifying 168 significant SNPs and related genes associated with temperature variation and environmental adaptation, focusing on traits like isothermality and pathways related to immune response and system development.

This study identified 374 eQTLs in scalp hair follicles associated with genes involved in metabolic, mitotic, immune processes, and responses to steroid hormones, contributing insights into genetic variation and hair traits.

This review discusses the possible impacts of prolactin on skin conditions like psoriasis, alopecia, and stress-related dermatoses, emphasizing the need for further research to explore its therapeutic potential.

This review provides a framework for diagnosing acquired scalp alopecias and discusses both non-scarring and scarring types, but reports no new clinical results.

In this study, researchers identified immune differences in children with alopecia areata, finding that cytokine profiles vary based on the presence of atopic diseases; notably, patients with atopy showed a heightened T helper 2 response, potentially influencing cytokine expression and disease severity.

This study used bioinformatics to explore molecular differences in testicular and ovarian responses to SARS-CoV-2, identifying genes that could be associated with sex differences in infection outcomes.

This study highlights that ZNF750, a zinc-finger transcription factor, is crucial for epidermal differentiation and barrier formation in skin by activating genes involved in lipid processing and stratum corneum development, and links ZNF750 sequence variations to skin inflammatory diseases like psoriasis.

This study found cell-specific variations in POMC mRNA and peptide expression in murine skin, suggesting that PC1 and PC2 convertases contribute to differential POMC processing.

This review analyzes the wide range of extrapulmonary symptoms in COVID-19, highlighting variations in severity from mild cases with anosmia to severe cases impacting major organs.

This study identified at least four distinct fibroblast populations in adult human skin, each with unique functional properties, suggesting potential therapeutic applications for wound healing and fibrosis-related diseases.

This study observed that a targetoid polycyclic concentric hair regrowth pattern appeared in some male patients with alopecia areata following treatment, indicating a positive sign of recovery despite unclear etiopathogenesis.

In this study, researchers found that impaired cholesterol biosynthesis in hair follicles may trigger an inflammatory immune response linked to primary cicatricial alopecia, providing new insights into the disorder's pathogenesis.

In this study, researchers found that the variability in growth factor expression, particularly TGFβ1, in PRP samples could influence patient responses to hair loss treatment with PRP therapy.
