This review discusses the host genetic factors influencing COVID-19 susceptibility and pathogenesis, highlighting genetic variations that affect viral entry and immune responses, but reports no new experimental results.

This review discusses the growing role of colorimetric sensors in food safety, highlighting their potential to enhance detection accuracy and manageability, while also noting challenges such as environmental interference and the need for further industrial validation.

In this study, transfection experiments showed that mutations in the K85 gene affect filament formation with K35, which may impact hair formation related to ectodermal dysplasia.

This study found that paracellular transport significantly contributes to the intestinal permeability of minoxidil, suggesting its limited suitability as a Biopharmaceutics Classification System reference drug due to potential variability.

This narrative review explores the strong association between various chronic inflammatory skin diseases and metabolic syndrome, emphasizing shared inflammatory pathways and chemokine involvement, though the precise molecular connections remain partially understood.

In this retrospective case series, baricitinib showed effectiveness in treating alopecia areata, with some potential benefits for psoriasis, but it may not be suitable for managing psoriatic arthritis in patients with these coexisting conditions.

This study discovered that calcium dependent protein kinase 1 (CPK1) directly activates cyclic nucleotide-gated channels 5, 6, and 9, promoting root hair growth in Arabidopsis by regulating Ca²⁺ signaling.

This study found that the topical Shen Bai hair growing decoction may improve androgenetic alopecia in mice by suppressing TNF-α and IL-6 levels, enhancing follicle density, and reducing apoptosis.

This source reviews popular cosmeceutical ingredients for skin care, noting that while they are popular among consumers for anti-aging benefits, many lack robust clinical evidence for their efficacy and safety, as they are not regulated by the FDA.

This study reviews current treatments for PCOS and evaluates Tirzepatide as a potential option for its management, suggesting possible benefits for those with obesity and metabolic syndrome but not for those of normal weight.

In this study, Caizhixuan hair tonic was found to promote hair growth in androgenetic alopecia mice by regulating the PI3K/Akt and apoptosis pathways.

This study found that adenosine promotes hair growth by stimulating the Wnt/β-catenin pathway in cultured human dermal papilla cells through activation of the adenosine receptor.

This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

This study demonstrates that an injectable gelatin-based hydrogel incorporating zirconium and quercetin promotes diabetic wound healing in vivo by enhancing angiogenesis, collagen deposition, and hair follicle regeneration while providing antibacterial and oxidative stress protection without detectable cytotoxicity.

This review discusses the growing importance of hydrogel scaffolds in skin wound healing, highlighting their unique properties and recent advancements in their use for treating difficult tissue damage, particularly within tissue engineering.

This study found that newly developed nanogels for transdermal delivery of finasteride were stable, showed excellent drug permeation through the skin, and ensured biocompatibility without causing irritation or toxicity.

This study observed that the binding of certain hormones in rat skin varies cyclically with the hair cycle phases, with testosterone showing maximum binding in the catagen phase.

This study found that the binding and release of BMP-2 from kerateine biomaterials are significantly influenced by pH and salt concentration, highlighting the potential for developing improved bone repair systems.

This study suggests that estrogen regulates vitamin A metabolism in skin tissues in a sex-dependent manner, which may have implications for treating acne, hair loss, and skin immunity.

In this study, Diane treatment in women with androgenetic alopecia led to normalization of hormone levels and improved hair condition, including less greasiness and reduced hair loss.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

This study introduces a new test using a pendulum device to assess the bending stiffness of hair fibers, which can evaluate the effects of different hair treatments.

This letter challenges an interpretation of results from a zinc lozenge trial that suggested patient perceptions of receiving treatment might indicate effective blinding, arguing this only holds for crossover studies.

This commentary discusses challenges in maintaining proper blinding in placebo-controlled trials, illustrated by a study where zinc and placebo lozenges were nearly indistinguishable in taste by participants.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

This study suggests that human trichohyalin may function as a flexible rod linking keratin intermediate filaments and as a scaffold protein in hair follicle and epidermis cell envelopes.

In this study, a novel mutation in the glucocorticoid receptor gene was identified in a young woman, impairing glucocorticoid signaling and leading to generalized glucocorticoid resistance.

This study suggests that S100A4 and S100A6 proteins may play key roles in activating stem cells for hair follicle regeneration in mice.

This study found that HB-EGF and TGF-α work together to stimulate wound healing in a murine model of thermal injury, with peak keratinocyte proliferation observed by postburn day five.
