This study demonstrates that pH-responsive nanogels designed with comb-like anionic polymers significantly improved oral delivery of the chemotherapy drug camptothecin, enhancing drug stability in acidic conditions and release in the intestines, with increased cellular uptake and cytotoxic effects against colorectal carcinoma cells.

This study described a novel three-dimensional-printed microneedle system designed for improved transdermal delivery of minoxidil to treat hair loss, demonstrating effective hair regrowth and safety in a mouse model while allowing sustainable needle base recovery.

In this study, researchers discovered that several compounds, including brequinar and 6-azauridine, exhibit significant anti-Zika virus activity using a high-throughput screen assay.

This study observed that dandruff in Indian women is associated with a distinct scalp microbiome, including specific bacterial and unknown Malassezia species, with implications for nutrient homeostasis and cell-host adhesion pathways.

The conclusion is that women under 35 should start fertility checks after 12 months of trying to conceive, women over 35 after 6 months, and women over 40 should start immediately. The checks should include ovulation status, reproductive tract structure, and male partner's semen evaluation.

In this study, a newly developed nanoparticle-loaded hydrogel wound dressing demonstrated significant antibacterial, antioxidant, anti-inflammatory, and proangiogenic activities, effectively reducing pain and promoting healing in a murine burn wound model while preventing infection by *Staphylococcus aureus*.

This study found that men with persistent sexual side effects after using finasteride for androgenetic alopecia had higher androgen receptor expression in certain tissues compared to those who never used the drug.

This review discusses recent advances in understanding the Eda pathway's role in developmental biology, and highlights ongoing trials and areas for further research, including Eda's potential involvement in cell processes and disease.

In this study, researchers found that L-cysteine interacted electrostatically with anionic ions on the surface of keratin fibers in human hair, reducing the rate of disulfide bond disconnection at pH 9.0.

This study suggests that the hydrogel nanoparticle formulation of hair growth-promoting compounds may enhance hair follicle penetration and induce hair growth in tested models, demonstrating its potential as a hair growth treatment.

This study found that combining celecoxib with chemotherapy improved overall survival, disease-free survival, and quality of life in gastric cancer patients with positive COX-2 expression without increasing adverse events.

In this study, PEG and keratin scaffolds selectively influenced protein release rates based on charge and size, suggesting their potential for targeted delivery of protein therapeutics.

This review reports that platelet-rich plasma may be more effective for musculoskeletal conditions when prepared with high platelet doses and low leukocyte content, but further trials are needed to confirm optimal formulations.

This study used melamine formaldehyde particles to measure a pH gradient along the hair shaft, showing a significant pH decrease from the hair sheath to the external shaft.

This study found that the cross-section trichometer is a promising tool for measuring hair mass index with high reproducibility, suggesting potential clinical and research applications.

This study found that mixtures used in permanent hair dyes had irritant effects on reconstructed human epidermis, while individual ingredients alone did not.

In this study, researchers developed a self-assembling hydrogel called RADA-PDGF2 and found it to accelerate wound closure in a mouse model due to its pro-proliferative and pro-migratory properties, without causing cytotoxicity or immunogenicity.

This review discusses the clinical guidelines for hidradenitis suppurativa, detailing its definition, impacts, and treatments, and includes a proposed therapeutic approach algorithm, but reports no new clinical findings.

This review covers the pathophysiology, diagnosis, evaluation, and treatment of hirsutism and reports no new clinical findings.

This study describes a method to extract and characterize keratin particles from human hair, finding they can encapsulate the anticancer drug Paclitaxel with significant efficiency, releasing it in a pH-dependent manner potentially beneficial for targeted cancer treatment.

This study observed that proteins in the mTOR signaling pathway are expressed differently in the hair follicles of patients with lichen planopilaris and frontal fibrosing alopecia, suggesting a role in the pathogenesis of these conditions.

This study found that polyquaternium-68 at pH 9 achieved the greatest hair deposition, while polyquaternium-44 demonstrated the best wash resistance at pH 6.

This study found that a self-emulsifying formulation with eugenol in emu oil improved hair conditioning and growth in rats, showing rapid hair increase after an initial delay compared to minoxidil.

This study reported that X-ray microscopy provides more intact images of hair's internal structure compared to transmission electron microscopy, particularly for observing fine details like cuticle coarsening and cortex cracks.

In this study, a newly engineered scaffold, PADM-MX-Ag-Si@Dox, demonstrated potential as a multifunctional biomaterial for postoperative melanoma treatment by controlling drug release, enhancing wound healing, and enabling real-time tumor surveillance through temperature, pH, and electrical stimuli.

This review discusses cultural hair care practices for African American scalp health and recommends combining clinical evaluation with cultural knowledge, but reports no new research findings.

This study found that a phytosome lotion made from Mangkokan leaf extract, using a green solvent and microwave-assisted extraction, demonstrated greater hair growth activity than 2% minoxidil, with the 30% phytosome lotion showing the highest efficacy in increasing hair length, weight, and diameter.

In this study, researchers found that stress likely triggers symmetrical alopecia in Formosan macaques in Mt. Longevity, Taiwan, with higher stress hormone levels associated with the condition.

This review highlights recent developments in nanovesicular carriers for enhancing molecule delivery into and across the skin, focusing on the design and evolution of phospholipid and non-phospholipid systems used in cosmetics and treating various skin conditions.

This review summarizes the link between acne pathogenesis and skin barrier dysfunction, noting that more severe acne correlates with greater skin barrier damage, but reports no new clinical results.
