This study found distinct hair metal profiles in Parkinson's disease patients, with lower iron and copper, higher manganese and arsenic, and explored their link to gut dysfunction and microbiota dysbiosis, suggesting hair metal analysis as a promising diagnostic tool.

This review discusses the potential uses of inorganic nanomaterials for imaging and detecting brain diseases, but reports no new experimental results; it calls for improvements in diagnosis precision and imaging accuracy.

This study found that finasteride- and dutasteride-loaded iron oxide nanoparticles improved drug penetration in the skin, suggesting they may be promising for topical alopecia therapies.

In this study, adrenalectomy in rats on a diet lacking certain vitamin B components reversed fur graying and enhanced hair growth.

This article discusses the association between chronic diffuse telogen hair loss in women and iron deficiency, supporting the view that iron's role is unclear and often overstated, but reports no new clinical results.

This review outlines drug repurposing as an efficient, low-cost strategy to identify new uses for existing drugs, highlighting various computational and experimental approaches as well as publicly available databases to aid in personalized pharmacotherapy.

This study suggests that adult hair follicle stem cells can survive and potentially differentiate into neuronal cells after being transplanted in a mouse model of traumatic brain injury, indicating promise for TBI therapy.

This study observed that gerbils exhibit a different wound healing mechanism compared to mice, with lower TGF-B1 expression and distinct tissue responses, yet achieve similar healing outcomes.

This article reviews skin disorders in Parkinson's disease, highlighting the potential of skin studies and stem cell research to advance understanding and treatment of the neurodegenerative disorder, without presenting new results.

This review discusses the potential of three-dimensional printed mesoporous scaffolds for drug delivery applications, particularly for bone cells and tissues, but reports no new clinical results.

This study found that Cur-Fe-mesoporous silica nanoparticles synergistically inhibited scar formation and promoted hair follicle regeneration in skin burn wound healing by releasing bioactive components like SiO32−, Fe3+, and Fe-Cur chelates.

This review found that patients with alopecia areata may have lower levels of vitamin D, zinc, and folate, but conflicting evidence precludes definitive clinical recommendations for micronutrient supplementation.

This study found that cadmium levels were significantly higher in women with chronic telogen effluvium compared to healthy controls, suggesting cadmium toxicity might contribute to this hair shedding condition.

This study found that iron availability influences root hair growth under phosphate starvation by affecting auxin distribution, phosphate starvation-responsive genes, and vesicle trafficking.

In this study, polydopamine emerged as a safe and effective alternative to traditional hair dyes like PPD for dyeing gray hair permanently, showing resistance to detergents and causing less toxicity and hair loss in mice.

This review examines drug repositioning as a strategy for combating bacterial infections, highlighting its potential to address multidrug-resistant strains and antibiotic resistance by analyzing safety profiles, synergistic combinations, and promising results for drugs initially used for other conditions.

In this study, higher concentrations of environmental metals, particularly manganese, were linked to worse self-reported attention-related behaviors in adolescents from Italy, with no significant modification of this effect by iron status.

This review discusses how various nutrients, such as flavonoids, probiotics, and omega-3 fatty acids, may support brain health by targeting stress-related pathways, potentially offering protective effects against neurodegenerative and psychiatric disorders through their roles in oxidative stress reduction and neuroinflammation regulation.

This review discusses how mineral deficiencies, particularly iron and zinc, affect health globally and explores bio-fortification and other strategies to combat these deficiencies, but reports no new experimental results.

This review discusses the roles of resident macrophages in the liver and lung, emphasizing their unique contributions to maintaining tissue homeostasis and the interface between circulation and external environments, but reports no new findings.

In this study, the novel fatty acid-conjugated tetrapeptide Palmitoyl-GDPH enhanced wound healing in rats by improving re-epithelialization and collagen deposition with minimal toxicity observed at the used dosage.

This review explores the potential of metal nanoparticles as innovative treatments for alopecia, highlighting their effectiveness in promoting hair regrowth, enhancing drug delivery, and modulating gene expression while also assessing the related experimental methodologies and regulatory considerations.

This review discusses recent advancements in nanotechnology-based treatments for chronic wound healing in diabetic models, noting that despite promising results, these innovations have yet to translate into widely available commercial products.

This study examined the factors contributing to gray hair, such as genetics and lifestyle, and found that while graying correlates with some health conditions, it is primarily a physiological process rather than a pathological one.

This review discusses the role of mineral nutrients in human health, emphasizing the importance of dietary sources and education to prevent mineral deficiencies, and reports no new clinical results.

A woman's unique dementia was misdiagnosed, a genetic mutation increases Parkinson's risk with age, and finasteride may help with Tourette syndrome.

This book discusses various unanswered questions about headaches, including genetic factors, smartphone effects, and botulinum toxin's potential benefits for chronic migraines, but reports no new clinical findings.

This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.

This review examines microneedle patches for drug delivery, detailing their designs, materials, manufacturing methods, and potential advantages, but reports no new clinical results.
