This review discusses the critical parameters for MALDI IMS sample preparation in skin analysis and highlights its applications in wound healing, neoplasia, and infection research, but reports no new clinical results.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

Continuous light exposure in rats leads to PCOS-like symptoms and suggests sleep habits might affect the disorder's development.

This study found that the keratin matrix in mammalian hard α-keratins is crucial for maintaining stiffness in water by controlling intermediate filament hydration.

This study found that using hair steroid profiling, dutasteride treatment led to reduced dihydrotestosterone levels and DHT/testosterone ratio in patients with male-pattern baldness.

This review discusses hair transplant techniques for female pattern hair loss and reports no new clinical results; it highlights the benefits of transplants combined with various treatments for improved hair density and styling options.

This study identified a novel CDH3 mutation associated with sparse hair and pigmentary macular changes in two siblings with hypotrichosis but no visual symptoms.

This study found that increased MSI2 expression in hair follicle stem cells can delay hair growth by maintaining stem cell quiescence and repressing Hedgehog signaling.

This study observed that patients with alopecia areata had decreased odds of developing stroke and a potential decreased risk of acute myocardial infarction, though the latter was not statistically significant.

This study found that four microRNAs, which were significantly upregulated in balding hair follicle papilla cells, could play a role in the development of male pattern baldness.

This study found that male liver cirrhosis patients have higher estradiol levels and lower dehydroepiandrosterone sulfate, leading to hormonal imbalances favoring estradiol, but without changing sex hormone-binding globulin's binding properties.

In this study, finasteride treatment did not negatively impact bone development or density in male rats, suggesting that DHT deficiency is not harmful to the male rat skeleton.

In this study, researchers found that severe androgenic alopecia in hospitalized men was associated with a higher likelihood of testing positive for COVID-19.

This study suggests a possible link between late puberty onset and decreased prostate cancer risk, while over-the-counter ibuprofen use was associated with increased risk.

This review discusses factors affecting fertility in both men and women with congenital adrenal hyperplasia and emphasizes individualized preconception management but reports no new clinical results.

This study found that early-onset male pattern baldness was associated with a reduced relative risk of prostate cancer.

In this study, mannosylerythritol lipids from soybean oil notably increased fibroblast and papilla cell viability, suggesting potential as a hair growth agent.

This review discusses five genetic fate mapping methods used to study cell behaviors during development and regeneration, detailing the necessary tools and considerations without reporting new experimental results.

The gene for Marie Unna hereditary hypotrichosis is located on chromosome 8p21.

This paper reviews diffuse androgen-dependent alopecia and chronic telogen effluvium in women, highlighting diagnostic challenges and management issues, but reports no new clinical findings; the authors suggest effective treatments are available.

This study reports that a sarcoptic mange outbreak, likely originating from mange-infected llamas from a governmental program, dramatically reduced vicuña and guanaco populations in San Guillermo National Park, Argentina.

This report describes a neurometabolic disorder linked to gain-of-function variants in the ODC1 gene, characterized by developmental delay, ectodermal abnormalities, and notable facial and neuroimaging features.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

This study observed that frontal plus moderate vertex baldness at age 45 was associated with a higher risk of aggressive prostate cancer in a large cohort.

In this study, there was no evidence that using 5α-reductase inhibitors for either short or long durations increased the risk of male breast cancer.

This study found that increased hair cortisol levels, indicating stress, were associated with greater hair loss in captive rhesus macaques, although the causality of this relationship remains unclear.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

In this study, researchers found that the existing Norwood and Hamilton classifications for androgenetic alopecia in Indian males had significant limitations, with 18% of cases not fitting into existing pattern categories.

Finasteride temporarily lowers male rat fertility without affecting libido.

In this study, a UK expert panel discussed strategies for managing common side effects of vismodegib, a hedgehog pathway inhibitor used for advanced basal cell carcinoma, concluding that adverse events like taste disturbances and muscle cramps can be effectively managed to optimize treatment duration.
