This review examined how COVID-19 infection and vaccination might affect sexual activity, sex hormones, and menstrual cycles in men and women, and found no evidence of COVID-19 transmission via semen.

This review highlights the promising potential of microemulsions and nanoemulsions in (trans)dermal drug delivery, noting a gap in understanding their distinct mechanisms and composition-related effects on skin permeability, while emphasizing the limited clarity on mesostructures and cosolvent impacts.

This study found that children with pituitary dwarfism had higher zinc and copper hair concentrations and lower manganese concentrations compared to healthy children.

In this study, researchers developed a regression model that reasonably predicts consumer-perceived hair breakage using various parameters such as hair smoothness, detangling forces, extensional strength, and hair density among Indian women.

In this study, researchers found that women with PCOS and thyroid dysfunction had significantly altered T3 and T4 hormone levels and more frequent symptoms like weight gain and irregular menstrual cycles, suggesting the importance of thyroid screenings for personalized treatment strategies.

Treating chronic hand eczema costs about the same in statutory and occupational health insurances in Germany, but work-related cases may lead to higher indirect costs due to longer work absences.

This study presents a new method called scMC that effectively distinguishes biological from technical variation in single-cell genomics datasets, demonstrating its ability to accurately align and detect biological signals across various experiments.

This systematic review reports that "COVID toes" and other skin manifestations can be initial signs of COVID-19, and advises immunosuppressive therapy adjustments only for infected or at-risk patients.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This systematic review reports that for patients with underlying dermatologic disorders who contracted COVID-19, most experienced mild to moderate exacerbation of their skin conditions and were managed similarly to the general population, suggesting treatment discontinuation during acute infection may prevent severe recurrence.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This review explores the potential genetic and epigenetic influences on hair whorl patterns and suggests that pattern formation may involve basic physical-chemical laws, although it reports no new experimental findings.

In this review, the authors discuss the potential for cell therapy, such as hematopoietic stem cell transplantation and mesenchymal stromal cells, to treat severe psoriasis unresponsive to biological therapies, while highlighting the associated risks, costs, and regulatory challenges.

This study found that the heat shock cognate protein Hsc70 was differentially expressed by dihydrotestosterone treatment in SV40-transformed dermal papilla cells, suggesting its involvement in androgen action on these cells.

This study found that women with acne and oligomenorrhea have higher levels of biologically active testosterone compared to those with acne and normal menstrual cycles.

The Naked gene in mice causes abnormal sebaceous glands and disrupts hair follicle organization.

This study analyzed changes in the microbiota during antler velvet regeneration in sika deer and found significant differences in microbial community composition between 15 and 30 days post-pedicle casting, highlighting the potential roles of specific bacteria in wound healing and tissue regeneration.

Biologicals are increasingly used in medicine and cosmetics, especially for skin and hair treatments, but more research is needed.

This study explores the development of a liposomal gel containing andrographolide from the plant Andrographis paniculata to potentially improve psoriasis management by enhancing drug delivery and reducing side effects of conventional treatments.

Hidradenitis Suppurativa is likely an autoinflammatory disease, and better understanding its causes could improve treatments.

Hidradenitis Suppurativa is a chronic skin condition best treated early with surgery for better outcomes and less recurrence.

This study found that psoriasis patients on biologic therapy had significantly lower anti-COVID19 IgG antibody levels after vaccination compared to healthy individuals not on biologic treatment.

This study found that psoriasis patients value medication providing substantial clearance of symptoms at an average of $34,208/year, significantly below the annual cost of biologic treatments.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This review discusses the potential mechanisms by which androgens may elevate blood pressure, particularly through impacts on the renin-angiotensin system, but reports no new experimental results.

In this study, the disruption of Gh/tissue transglutaminase in mice did not affect viability but reduced thymocyte viability and fibroblast adhesion, suggesting its role in cell stabilization and extracellular matrix interactions.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This study identified a domain on human chromosome 21q22.1 containing various high glycine-tyrosine and high sulfur keratin-associated protein genes, revealing their diverse expression in hair-forming cells.

This study highlights the evolving understanding of acne's pathophysiology and suggests that targeting pro-inflammatory cytokines such as IL-1β, IL-17, IL-23, and TNFα with biological antibodies may offer new treatment strategies for severe acne and its scars.
