This abstract does not contain specific research findings or results, but instead provides information related to the JAMA Dermatology journal's online platform and services.

In this study, severe hair loss occurred in PKC epsilon transgenic mice treated with DFMO during skin tumor prevention, highlighting a link between polyamine biosynthesis, hair follicle maintenance, and metastasis suppression.

This study found that the natural alkaloid cepharanthine effectively inhibited porcine epidemic diarrhea virus infection in newborn piglets.

The researchers reported that human foreskin fibroblasts isolated by enzyme digestion method proliferated faster and were purified more quickly than those isolated by the inverted tissue culture method; additionally, post-psoralen photoactivation therapy moderately repaired UVB-induced damage in these fibroblasts, suggesting potential clinical applications.

This study suggests that fecal microbiota transplantation was effective in reducing symptoms of feline hyperesthesia syndrome, with most cats showing clinical remission or improvement and no observed side effects.

This theoretical research project proposes the Carnivore Follicular Integrity Framework, suggesting that animal-based diets may support hair follicle stability through various evolutionary and mechanistic pathways.

This study found that new methods for isolating human dermal papilla cells were more efficient than traditional methods, maintaining higher levels of specific markers and improving the cells' research potential.

This paper presents consensus guidelines for standardized diagnostic criteria and assessment methods for frontal fibrosing alopecia to improve clinical research and data collection globally.

In this study, Dodatek A operationalizes the Functional Androgen Axis framework by defining three system-level indices and an efficiency metric to describe androgen function, incorporating key methodological improvements and acknowledging significant limitations for future empirical validation.

This research presents the Dodatek A model, elaborating on androgen function through new mathematical indices and methodological improvements, shifting focus from serum hormone concentrations to system interactions to better describe androgen activity comprehensively.

The researchers in this study identified molecular mechanisms involved in frontal fibrosis alopecia, highlighting immune response and fatty acid metabolism, and developed a four-gene diagnostic model showing high accuracy in distinguishing affected individuals from controls.

Quickly fix tissue in formalin after excision to preserve it.

In this study, finasteride was found to induce tissue-specific P-glycoprotein activity in the liver and kidney of rabbits after a 14-day treatment period.

This study found that activation of Wnt/β-catenin signaling in mouse testes promotes spermatogonial differentiation and reduces the stem cell pool, with SHISA6 inhibiting this process and maintaining stem cell characteristics.

This study found that endocrine therapy for breast cancer is associated with a pattern of hair loss similar to androgenetic alopecia, negatively impacting quality of life despite mild severity.

This study found that permanent chemotherapy-induced alopecia was relatively common three years after treatment among breast cancer patients receiving adjuvant chemotherapy, particularly those on taxane-based regimens.

This review discusses clinical features, differential diagnosis, and treatments for female pattern hair loss, emphasizing the use of 2% topical Minoxidil and exploring alternative off-label therapies.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This review explores the role of Eph receptors and ephrins in skin cell processes, discussing their potential for therapeutic targeting in dermatological disorders, but it presents no new research findings.

This article reviews trichoscopic signs of chemotherapy-induced alopecia, including exclamation marks, but reports no new clinical results.

This study found that CDK4/6 inhibitors in hormone-positive metastatic breast cancer were linked to increased risks of fatigue, alopecia, and stomatitis compared to placebo.

This study found that chemotherapy in female breast cancer patients caused significant early hair loss, which began to recover three months after completion, whereas tamoxifen did not affect hair growth.

This case report describes a 26-year-old female with linear morphea and unique alopecia characterized by atrophic follicular remnants, resembling telogen follicles but indicating permanent alopecia, unlike typical findings in morphea-related alopecia.

Chemotherapy can cause significant hair thinning and changes in hair texture, while tamoxifen has a smaller effect.

This article explores the potential of combining biomarkers to assess and improve treatments for chemotherapy-induced alopecia, highlighting the limited availability of data on hair follicle damage markers with and without scalp cooling.

This study found that a PRP-like cosmetic product called TR-M-PRP plus significantly improved hair growth in individuals with alopecia areata over three months, as measured by the SALT score, suggesting it could be a safer alternative to traditional PRP treatments.

This review outlines the diverse clinical presentations of cutaneous metastases in breast cancer patients and emphasizes the importance of biopsy for accurate diagnosis, but reports no new results.

This review provides an updated overview of the symptomatology, diagnosis, trichoscopy findings, and treatment options for eyebrow and eyelash alopecia, but it reports no new experimental results.

This case report describes a 22-year-old woman who developed persistent, non-scarring hair loss and premature ovarian failure following a myeloablative umbilical cord transplant for acute myeloid leukemia.

This study found that finasteride administration in hamsters led to significant spermatogenesis reduction and seminiferous tubule atrophy compared to the control group.
