This chapter reviews studies on the side effects of cytostatics and immunosuppressive drugs, detailing various toxicities such as cardiovascular, pulmonary, and neurotoxicity, but provides no new clinical results.

In this study, 1% procyanidin B-2 tonic significantly increased the number of total and terminal hairs on the scalp of male participants compared to a placebo after 6 months of use.

This review discusses genetic and epigenetic mechanisms that may contribute to aging and presents models suggesting that chromosomal changes could play a key role in the aging process; it reports no new experimental findings.

This study investigated the effects of ultrasound-assisted extraction on sunflower seed oil mixed with defective green coffee grains, finding that higher coffee grain ratios decreased oil yield but increased phenolic content and antioxidant activity, with potential applications for wound treatment.

This study optimized conditions for quantifying minoxidil using high-performance liquid chromatography, establishing specific parameters for mobile phase, flow rate, column temperature, and retention time.

This study introduced mechanical setups to analyze the mechanical properties of root hairs in Arabidopsis thaliana, finding that axial stiffness primarily relates to tip compression and turgor pressure, confirmed by independent methods adapted from work on animal cells.

This study found that cortisone reductase deficiency is caused by inactivating mutations in the H6PD gene, affecting cortisol metabolism by preventing 11β-HSD1 enzyme function.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.

This study reports a unique case of common variable immunodeficiency with autoimmunity linked to a heterozygous S250C variant in the autoimmune regulator gene, suggesting a potential molecular basis for this combination.

This study found that dutasteride treatment in pregnant mares significantly increased progesterone concentrations but did not alter gestational length or neonatal outcomes.

This review details the causes, symptoms, and treatments for dandruff, emphasizing herbal ingredients with anti-dandruff properties used in shampoos and exploring their antifungal and anti-inflammatory mechanisms. It highlights dandruff's exploitation by personal care companies due to the lack of medical interventions.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This study found that macrophages play a crucial role in nerve regeneration by regulating Schwann cell dynamics and remyelination, with Gas6 identified as a key factor in this process.

This review discusses evidence-based guidance for managing primary cicatricial alopecias but reports no new clinical results, highlighting significant gaps in knowledge and the need for more quality trials.

This review discusses the role of pharmacological sciences in advancing regenerative medicine technologies but reports no new experimental findings; the authors advocate for increased pharmacologist involvement to drive innovations.

Finasteride slows down motherly behavior in first-time pregnant rats.

This study found that LY320236 is a competitive inhibitor of type I and a non-competitive inhibitor of type II steroid 5alpha-reductase, indicating its potential as a dual inhibitor with differing modes of activity.

This study found that AtCEPs in Arabidopsis thaliana play a role in controlling root hair growth by processing EXT proteins, with NAC1 acting to regulate their expression and influence elongation.

Educational efforts can reduce harmful chemical exposure from hair products in pregnant Women of Color.

This review discusses the definition of polycystic ovary syndrome proposed by the AE-PCOS Society Task Force, emphasizing hyperandrogenism, ovarian dysfunction, and excluding related disorders, while noting potential variations needing more research.

This study found that hair follicles in mice and humans can convert wound-related myofibroblasts into adipocytes, suggesting a potential pathway to reduce scar formation by activating BMP signaling.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This study found that removing PPARγ specifically from mouse adipose tissue led to severe fat loss, insulin resistance, diabetes, and associated metabolic abnormalities.

This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This review discusses the various stem cell populations associated with hair follicles and their potential in regenerative medicine, highlighting differences between murine and human hair follicles but reports no new clinical results.

This study found that the protein MIM is crucial for maintaining cilia and Sonic hedgehog signaling in mesenchymal cells by counteracting Src-mediated phosphorylation of Cortactin, impacting hair follicle formation.

This study reports that C3H/HeJ mice and DEBR rats serve as effective models for screening potential treatments for human alopecia areata, despite certain challenges in predictability and cost.

This study demonstrates that canonical Wnt signaling is crucial for maintaining thymic epithelial microenvironments in postnatal thymus, possibly by affecting TEC progenitor cells.

This study found that Florida manatees have unique types of specialized nerve endings in their vibrissae, which assist in their sensory and manipulative functions in aquatic environments.
