In this study, researchers developed a non-invasive method to distinguish exogen hair from telogen hair on the human scalp, finding that normal exogen hair levels are generally less than seven hairs per cm².

In patients undergoing treatment with capecitabine for colon cancer and metastatic breast cancer, this study observed that hand-foot syndrome occurred more frequently than with intravenous 5-FU, but other side effects were less common.

This review discusses the pharmacological properties and physiological regulation of neuroactive steroids, focusing on their varied responses to stress and ethanol in rats, mice, and humans, but it reports no new findings.

This study found that Minoxidil had biphasic effects on normal human keratinocytes, stimulating proliferation at micromolar doses, but showing antiproliferative, pro-differentiative, and cytotoxic effects at millimolar concentrations.

This study found that measuring reproductive hormone levels in brown bear hair may effectively support non-invasive genetic sampling, though larger samples or more sensitive techniques are needed for broader application.

This review discusses the potential persistent adverse effects associated with 5α reductase inhibitor treatment for androgenetic alopecia but provides no new clinical results; it emphasizes the importance of discussing these risks with patients.

This study observed that psychological factors and serum levels of zinc, folate, and vitamin B12 may contribute to the development of trichodynia.

This study found that in the Thai population, hair density varies by scalp location and decreases with age, and that Asians generally have lower hair density compared to Caucasian and African populations.

This review discusses the common dermatologic side effects of epidermal growth factor receptor inhibitors and provides practical guidance for recognizing and managing these effects; it reports no new clinical results.

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 article describes cases of unusual scalp whorl patterns, including triple parietal and right temporal whorls, that were associated with normal development, and discusses theories of hair whorl development.

This review discusses various resveratrol derivative patents for therapeutic, nutraceutical, and cosmetic use, but reports no clinical results and notes that claims of improved efficacy lack trial evidence.

This review discusses the biology, pathophysiology, and management of eyelash anomalies, highlighting the need for more research into eyelash mechanisms and care, and reports no new clinical results.

This review discusses various skin changes during pregnancy, noting that while most are benign and resolve after childbirth, some may require careful medical management for the safety of the mother and fetus; it reports no new results.

This study observed significant differences in hair care practices and biologic hair parameters between Caucasian and African American women, which may contribute to varying hair fragility and growth.

This study reports that riboflavin may increase enzymatic activity in a GCDH-deficient patient with specific mutations, but doesn't fully normalize urinary organic acid levels.

This article reviews the roles and mechanisms of stem and progenitor cell migration in adult organs for tissue homeostasis and regenerative medicine, but reports no new experimental results.

This study found that non-ablative fractional erbium glass laser treatment affected gene regulation in human skin models by downregulating MMP and interleukin expression, suggesting potential roles in dermal remodeling and anti-inflammatory effects.

This study reported that etretinate treatment leads to increased hair shedding due to a sustained decrease in anagen duration, with an arrest at the onset of anagen and a follicular anchorage defect in telogen contributing to alopecia.

This review discusses the role of stem cell heterogeneity and compartmentalization within the epidermis and highlights their significance as niches for neighboring cells, without reporting new experimental results.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

This review discusses recent advancements and new approvals in the medical treatment of lower urinary tract symptoms, particularly highlighting drugs for nocturia and ongoing trials for multiple related conditions, while reporting no new clinical results.

This review discusses the role of contraceptives in dermatology, particularly for acne treatment and managing patients on teratogens, but reports no new clinical results.

This study found that C57BL/6 mice with a diet containing specific levels of vitamin A showed alterations in retinoid metabolism and increased frequency of cicatricial alopecias, suggesting dietary factors may play a role in this condition.

This study reported the development of a novel and reliable liquid chromatographic method to measure testosterone and epitestosterone in human urine, offering sensitive detection for doping control.

In this scoping review, researchers found that while some dietary approaches may help improve psoriasis symptoms—particularly in those with obesity or coeliac disease—the overall evidence is limited, and larger studies are necessary to identify effective diets for the broader psoriasis population.

The researchers reported that minor salivary gland stem cells exhibit stem cell characteristics and respond to tobacco-derived carcinogens, implicating the transforming growth factor beta pathway in their maintenance.

This study found that incorporating 0.5% TPGS into topical minoxidil solutions enhanced hair growth in mice, although increasing TPGS to 2% decreased effectiveness.

This review analyzes the impact of different preparation methods for platelet-rich plasma, human follicles stem cells, and adipose-derived stem cells on hair regrowth and wound healing, but reports no new results; the authors emphasize convincing evidence of positive outcomes despite protocol variability.

In this study, vitiligo and alopecia areata were more common among patients with chronic graft-vs-host disease than previously reported, linked to higher NIH skin scores and greater immunosuppressive treatment.
