In this case report, the researchers documented a rare instance of plica neuropathica, characterized by matted and twisted hair, occurring alongside diffuse alopecia, marking the first such documented association and emphasizing its diagnostic challenges in identifying causes of alopecia.

This study found that human placenta hydrolysate effectively inhibited atopic dermatitis development in stimulated human cells and a mouse model, suggesting its potential as a therapeutic agent for related skin diseases.

This study found that polymeric micelle formulations significantly improved the targeted delivery of adapalene to hair follicles compared to standard Differin® products, which suggests potential advantages in treating hair follicle-related conditions and reducing side effects.

In a porcine model, this study observed that using an External Tissue Expansion Device increased epidermis thickness, cell proliferation, and vessel density at fat graft recipient sites.

This study suggests that new cells are incorporated into the dermal papilla during the early anagen phase of the hair cycle, which may influence hair growth consistency and follicle size changes.

This study examined the use of keratin gel as a filler in nerve guides for peripheral nerve regeneration in a rat sciatic nerve injury model.

In this study, combination therapy with DPCP and anthralin promoted hair regrowth in 40.62% of alopecia areata patients who were unresponsive to DPCP alone, with response improving over longer treatment durations.

This study found that dexamethasone treatment inhibited the inflammatory response and the induction of ornithine decarboxylase activity in mouse skin after TPA application, although the effect on ODC was weaker during the hyperplastic stage.

This study found that PDCD4 protein expression is reduced in various skin cancers compared to normal skin, suggesting its potential role in preventing or treating certain skin cancers.

This study developed a quercetin-encapsulated and polydopamine-integrated nanosystem that reshapes the perifollicular microenvironment, showing potential for rescuing hair follicle viability and regenerating hair follicles in androgenic alopecia by scavenging reactive oxygen species and promoting angiogenesis.

Androgens reduce hair growth by affecting cell differentiation and blood vessel formation.

This study found that platelet-rich plasma treatment significantly improved erectile function and restored neural structures in aged rats with erectile dysfunction, suggesting potential benefits for geriatric patients.

This study found that DPP4 inhibition in mice can enhance hair follicle activation and regeneration, suggesting a potential therapeutic strategy for improving hair growth and wound-induced hair follicle neogenesis.

This study found that encapsulating dermal papilla spheroids in alginate hydrogel with extracellular matrix proteins increased alkaline phosphatase activity, suggesting an enhanced manipulation of dermal papilla activity.

This study evaluated the feasibility of a single-center, three-arm trial to assess fat grafting with or without PRP for diabetic foot ulcers, finding high patient engagement and indicating that a multi-center trial could be safe and feasible.

This study found that dermal papilla cells can induce hair follicle regeneration and maintain growth in vitro and in vivo, with higher ET-1 and SCF expression enhancing this ability.

This study found that TPA treatment transiently induces high levels of ODC in mouse epidermal cells, particularly around hair follicles, with localization reduced by retinoic acid or cycloheximide pretreatment.

This review discusses the role of the Wnt/β-catenin pathway in skin wound repair and explores how photobiomodulation may affect chronic wound healing, but it reports no new clinical results.

This review explores the recent developments and diverse applications of microneedles in drug delivery and diagnostic platforms but reports no new clinical results.

This review discusses the role of dermal papilla cells in hair follicle formation and their potential use in cell therapy for hair loss, but reports no new research findings.

In this study, a nanoparticle system codelivering diphenylcyclopropenone and rapamycin successfully induced immune tolerance and promoted hair regrowth in a mouse model of alopecia areata, offering a promising new therapeutic strategy for this autoimmune condition.

This study found that among patients with twenty-nail dystrophy, those treated with oral cyclosporine in combination with a dietary supplement showed significantly better improvement in nail condition and quality of life than those treated with the supplement alone.

This article discusses highlights from the 2019 Dermatology Nurses' Association's annual meeting, covering various dermatological conditions and treatments, and reports no new clinical findings.

This study reported improvement of psoriatic onychopachydermoperiostitis symptoms with the use of etanercept.

This study found that DPCP treatment led to cosmetically acceptable hair regrowth in 38% of patients with chronic severe alopecia areata, while adding 5% minoxidil showed no significant clinical benefit.

This case report suggests that topical diphenylcyclopropenone (DPCP) may be beneficial for treating both alopecia areata and verruca vulgaris, although it is not typically a first-line therapy.

This article discusses diabetic gustatory hyperhidrosis as a rare form of autonomic dysfunction linked to severe diabetic neuropathy and nephropathy, noting its impact on social and emotional well-being.

Inhibiting PGD2 and using dermal papilla cells may improve skin and hair regeneration.

This case report highlights a 12-year-old boy with twenty nail dystrophy in isolation, emphasizing the need for thorough physical exams to distinguish nail disorders and provide appropriate management and counseling on the condition's benign nature and good prognosis.

The project developed and tested a method using plasma rich platelets to treat hair loss.
