This review discusses various causes of hair loss, emphasizing the importance of a structured diagnostic approach, and reports no new clinical findings.

In this study, researchers found that replacing natural aggregates with animal bones and human hair with increased microroughness may improve the mechanical strength and durability of concrete.

This study found that bioconjugating 16-methylheptadecanoic acid (16-MHA) to damaged hair can mimic the protective properties of 18-methyleicosanoic acid (18-MEA), restoring the hair's structural integrity and moisture homeostasis, even after washing.

This review addresses the effects of testosterone on brain development and examines both the established sex differences in brain functions and the debate surrounding structural dimorphism in neuropsychiatric conditions.

This review summarizes evidence indicating that body image issues in patients with systemic lupus erythematosus should be addressed with the same importance as physical symptoms like pain and disability.

This article explores how narratives around racial and ethnic minorities versus fat individuals during the Covid-19 pandemic influenced the framing of these groups as "at-risk," with disparities in blame and responsibility linked to structural racism and anti-obesity rhetoric.

In this pilot study, topical latanoprost acid was observed to increase hair count and improve hair follicle structure in women with androgenetic alopecia, with no serious adverse events, suggesting potential for further investigation to confirm its efficacy and safety.

In this narrative review, the authors found that stigma related to oculocutaneous albinism in Africa is primarily driven by socio-cultural beliefs and structural inequities, affecting individuals' health, education, and psychosocial well-being, with interventions needed to dispel myths and provide specialized healthcare and support.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

In this report, a unique female presentation of IFAP syndrome is described, featuring musculoskeletal contractures but no photophobia, highlighting the importance of early detection and multidisciplinary care to improve outcomes and prevent disability.

This study reports a novel LSS gene mutation in an Egyptian family with alopecia intellectual disability syndrome 4, expanding the known clinical and genetic features of the condition.

This study found significant structural and compositional differences in hair affected by alopecia areata compared to healthy hair, using a range of physico-chemical investigation methods.

This review discusses the structural properties, pharmacological effects, and clinical applications of neurotoxins on synapses, reporting no new experimental results.

This study found that a sucrose-based crosslinker can effectively straighten hair and maintain durability in high humidity and through repeated washings without affecting the hair's tensile properties or causing surface damage.

In this study, a mixed-methods survey of 357 balding men revealed that baldness is structurally stigmatized, with many participants experiencing distress and using treatments to combat it; others resisted stigma and expressed minimal distress.

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 found that follicular unit-like wigs made from xenogeneic human hair and medical polypropylene exhibited good histocompatibility, a low loss rate, and satisfactory appearance one year after transplantation in rabbits.

This review covers various aspects of hair biology, pigmentation, and development, focusing on genetic and biochemical modulation of hair follicle components but reports no new findings.

This review highlights the potential of microfluidic skin-on-a-chip models in skin research, emphasizing their ability to mimic human skin structure and improve control over cellular and molecular distribution compared to traditional in vitro models.

This manuscript explores the development and future potential of injectable biomimetic gels in biomedical applications, highlighting their promise in wound healing and tissue regeneration, while also acknowledging challenges like mechanical durability and scalable production still persist.

In this narrative review, the authors discuss regenerative substances like platelet-rich fibrin and mesenchymal stem cells in biological aesthetics, noting that while these methods show promise for regeneration, their safety, effectiveness, and durability remain uncertain due to limited and heterogeneous evidence.

This study observed that treating human hair with NaOH led to partially removed cuticles, resulting in better fiber cohesion and mechanical properties similar to wool, unlike bleach or formic acid treatments, which weakened the fibers.

This study found that Silibinin-loaded polymeric micelles significantly protected human hair from UV-B induced structural and chemical damage by preventing increases in roughness and reducing protein loss.

This study found that wounds in sheep treated with mesenchymal stem cells and platelet-rich plasma showed improved healing, reduced inflammation and contraction, and better skin structure compared to untreated wounds.

This chapter reviews skin components, wound healing mechanisms, and the potential of biomaterials to enhance skin repair and regeneration, without offering new experimental results.

This review concludes that anabolic–androgenic steroid abuse may lead to significant neurotoxicity, affecting brain structure, neurotransmitter systems, and increasing the risk of mood disorders and cognitive deficits.

The researchers reported two brothers with a new variant of X-linked trichothiodystrophy associated with an RNF113A gene mutation, highlighting features such as intellectual disability and growth failure, but without previously reported endocrinological or genital abnormalities, underlining the importance of genetic counseling for such variants.

In this study, subcutaneous injection of bone marrow mesenchymal stem cells in burned rats significantly improved wound healing by reducing inflammation, scar formation, and wound size, and restoring normal skin structures.

In this study, researchers reviewed the progress and challenges in using hydrogels for 3D printing in biomedical applications, highlighting advancements in structural complexity, and identifying ongoing issues like resolution improvement, cell viability, and ethical concerns for clinical use.

This minireview discusses the mechanisms of facial aging, examines current literature, and proposes filler injection protocols, but it reports no new clinical results.
