In this systematic review, animal studies showed that cytarabine causes multi-organ toxicities, notably neurotoxicity, linked to oxidative stress and other mechanisms, though study quality raises concerns about reliability and translation to human outcomes.

In this study, researchers found that the histone demethylase UTX is crucial for regulating skin differentiation through retinoic acid signaling, mainly impacting females, as males compensate with a Y-linked paralog.

This study reported that during wheat polyploidization, decreased DNA methylation and specific hypomethylated promoters were associated with altered gene transcription, contributing to root hair elongation and improved nitrate uptake, highlighting the role of epigenetic regulation in enhancing crop traits.

The researchers in this study found that neonatal mouse skin fibroblasts show distinct chromatin landscapes directing differentiation into dermal papilla or adipocyte lineages, and such plasticity may inform strategies for enhancing regenerative capacities in adult skin.

This study found that Hairless (HR) and putrescine form a negative regulatory network that impacts epidermal homeostasis and hair follicle cycling, linked to the MYC superfamily's regulation of ODC expression.

Ancestry affects skin healing, with non-Hispanic Black patients showing more healing-related fibroblasts than White patients.

This study found no significant difference in the CAG and GGN repeat lengths between infertile and fertile men in Nigeria, but identified a unique GGN allele distribution in the Nigerian population compared to Caucasians.

This study identified differences in adverse symptoms among patients with post-finasteride syndrome based on short and long androgen receptor gene polymorphisms.

This review discusses sex differences in immune response to respiratory viral infections, including SARS-CoV-2, and highlights that hormones like estrogen may provide females with better protection, but it reports no new results.

This study found no significant difference in CAG repeat numbers of the androgen receptor gene between Han Chinese women with female pattern hair loss and healthy controls, suggesting it may not be a genetic marker for FPHL in this population.

This study identified five master regulators that mediate molecular differences in hair follicle development and sexual dimorphism in the skin, providing insights into male pattern baldness and hair follicle donor dominance.

This article reviews the role of microRNAs as epigenetic modulators in dermatology but reports no new clinical findings.

This study observed phenotypic diversity in hair loss among Japanese individuals homozygous for the LIPH c.736T>A mutation and suggests that differences in hair thickness may contribute to varying severities.

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 study found that abolishing H3K27me3 in mouse skin by targeting Ezh2 and Ezh1 affects hair follicle development and epidermal behavior, revealing functional differences between these tissues.

This review addresses the effects of testosterone on brain development and examines both the established sex differences in brain functions and the debate surrounding structural dimorphism in neuropsychiatric conditions.

This review discusses the insights gained from single-cell RNA sequencing of fibroblasts in various cancers and wound healing, highlighting differences in gene expression and novel interactions.

This review discusses the cellular and molecular changes involved in cutaneous wound re-epithelialization and EMT, highlighting their similarities and differences, but reports no new clinical results.

This article reviews the role of stem cells in tissue development, tumor formation, and organoid generation, and highlights the potential of epigenetic regulation in advancing regenerative medicine and cancer treatment, without presenting new experimental results.

This study suggests that cerebrospinal fluid levels of the neurosteroids allopregnanolone and pregnanolone correlate negatively with PTSD and negative mood symptoms, with potential sex-specific differences in synthesis enzyme blocks.

This study identified a novel missense MAFB variant in a family with some unaffected members, suggesting incomplete penetrance and the potential influence of modifier genes, epigenetic mechanisms, or environmental factors on MCTO phenotype.

This study found that, among fertile egg donors, the AR gene CAG polymorphism was associated with differences in antral follicle count but did not impact ovarian response to gonadotrophins.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.

This study found that large excisional wounds in mice can regenerate new hair follicles and fat, whereas similar wounds in rats across seven strains failed to do so, highlighting interspecies differences in regenerative capacity.

This study constructed a single-cell atlas of hair follicle cells from yaks and taurine cattle, revealing that differences in WNT signaling within dermal papilla cells may be key to the yak's adaptation to cold environments on the Qinghai-Tibet Plateau.

In this study, researchers observed that genetically identical cloned dogs, when exposed to different environments like an airport and a police station for two years, exhibited significant differences in toxic mineral concentrations and intestinal microbiota composition, suggesting that environment influences physiological traits even among clones.

In this case-control study, researchers investigated the association between SIRT1 gene polymorphisms and colorectal cancer risk, finding no statistically significant differences in polymorphism frequencies between patients and controls, but noted trends that warrant further study in larger populations.

This study found that kinematic alignment in total knee arthroplasty leads to a higher proportion of patients requiring smaller femoral components compared to traditional mechanical alignment, with statistical significance observed in femoral sizing differences between the two groups.

This abstract describes the processes for recognizing foreign medical degrees in the US and the reciprocal credentialing of US medical qualifications in Poland, highlighting differences in evaluation and certification requirements between the two countries.

This study identified non-structural proteins in preschool children's scalp hair that suggest potential biomarkers for brain development, immune function, and stress response with heritability and age-related differences.
