This study identified two novel genetic variants associated with Alzheimer's disease in APOE ε4 non-carriers, revealing insights into the disease's underlying regulatory mechanisms.

This review discusses the roles of sex hormones in COVID-19 progression and highlights conflicting evidence on their protective effects and the complexity of sex and gender influences on the disease.

This article discusses the potential genetic basis of central centrifugal cicatricial alopecia in women of African ancestry but does not provide new research results.

This review discusses recent advances in the genetic understanding of inherited hair and nail disorders and reports no new clinical results.

Neurosteroids in the brain can increase or decrease seizure risk in mice.

This review discusses how certain genetic, infectious, and metabolic conditions might influence disease severity and highlights the potential for new therapies, but it presents no new research findings.

The researchers suggest that testosterone levels might influence COVID-19 susceptibility and severity, with low levels potentially protecting against infection but possibly worsening severe disease due to cytokine storm activation.

In this study, women with PCOS who took 12 mg of Astaxanthin daily for 8 weeks showed a reduction in certain inflammatory markers and apoptosis-related genes, suggesting potential benefits for managing PCOS, though effects on symptoms like BMI and hirsutism were not significant.

Men have worse COVID-19 outcomes than women due to genetic and hormonal differences.

This study explored the relationships between virus susceptibility to infection and several factors, finding that higher heat tolerance and larger virus size correlated positively with infection susceptibility, while high humidity and higher mutation rates correlated inversely among eight RNA viruses, including SARS-CoV-2 and influenza.

This article provides a critical overview of recent discoveries in the genetics and molecular processes involved in androgenetic alopecia, focusing on its polygenic basis and DHT dependency, but reports no new clinical results.

This review discusses recent advances in understanding the cellular, molecular, and genetic factors contributing to lupus erythematosus and reports no new experimental findings.

This study found that women with post-adolescent acne experience marked menstrual irregularities, polycystic ovaries, androgenetic alopecia, hirsutism, and metabolic syndrome, but insulin resistance and dyslipidemia may not significantly contribute to their acne's pathogenesis.

This review discusses various forms of ichthyosis, including genetic and acquired types, detailing their characteristics, causes, and potential management strategies, but reports no new clinical results.

This review discusses the disruption of hormonal and metabolic rhythms in polycystic ovary syndrome and explores potential drug targets to address its molecular causes, without providing new clinical results.

In this study, researchers found that contrary to expectations, keratin 10 domains did not reduce cell proliferation and instead increased tumor development in genetically modified mice.

This study highlights that polycystic ovary syndrome develops through genetic and environmental factors, with insulin resistance as a key mechanism, impacting the risk of metabolic and cardiovascular conditions.

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.

The document describes a woman with familial Parkinson's disease due to a genetic mutation, showing severe symptoms and poor response to treatment, and suggests finasteride may help reduce symptoms in Tourette syndrome.

A woman's unique dementia was misdiagnosed, a genetic mutation increases Parkinson's risk with age, and finasteride may help with Tourette syndrome.

This study reported unexpected positive results in two males with androgenetic alopecia using a cyclodextrin-enabled, natural-based formula over 270 days, showing marked hair thickening and reduced scalp hair loss.

This study found significantly higher levels of Toll-Like Receptor 4, interferon gamma, and interleukin-17 in Iraqi patients with alopecia areata compared to controls, suggesting these immune markers play a crucial role in the disease's development and could be targets for future treatments.

This review discusses sex-based differences in immune responses, focusing on genetic, hormonal, and microbiome factors influencing infections like COVID-19, and reports no clinical results.

This review discusses the etiology of polycystic ovary syndrome, emphasizing the role of genetic and environmental factors, and reports no new experimental findings.

In this study, researchers identified 19 genetic risk loci and highlighted 16 candidate causal genes, including immune-related ones, associated with polycystic ovary syndrome, emphasizing the role of specific immune cells like T cells and NK cells in its pathogenesis.

This study found that IL-4 VNTR intron 3 and TNF-α (rs1799964) gene polymorphisms do not have a significant association with alopecia areata susceptibility in the Egyptian population.

Melanoma risk tools need improvement, certain gene mutations cause skin diseases and could be treated by targeting those mutations, skin wrinkling may relate to lung aging due to genetic factors, and oxidative stress affects hair loss but can be reduced in low oxygen.

In this case report, a 31-year-old man with frontal hairline recession saw a marked improvement in hair density and scalp appearance after undergoing six mesotherapy sessions alongside twice-daily application of 5% minoxidil, attributed to the treatment protocol combining nutrients, bioactives, and topical minoxidil.

This study found that the circadian clock in mouse skin regulates cell proliferation and affects sensitivity to UVB-induced DNA damage, with potential implications for understanding human skin cancer risk.

In this study, NIH hairless mice showed increased susceptibility to Listeria monocytogenes infection compared to NIH mice, potentially due to differences in gut microbiota and monocyte levels.
