This review summarizes the ethno-medicinal uses, phytochemical constituents, and biological activities of Acorus calamus, highlighting its potential therapeutic benefits and the importance of further scientific work on this plant.

This study found that plasmacytoid dendritic cells are central to the pathogenesis of alopecia areata, suggesting they may help differentiate it from trichotillomania and androgenetic alopecia.

This study found that macrophages are crucial for skin regeneration during tissue expansion, as their depletion in rats led to inhibited skin growth and reduced secretion of key growth factors.

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

This chapter reviews surface plasmon resonance (SPR) methodology and its applications in basic science and human disease without reporting new clinical results.

This review discusses the mechanisms and engineering techniques for enhancing the targeted delivery of extracellular vesicles in therapies but reports no new clinical findings; the authors encourage further exploration to advance clinical applications.

This study identified three genes with significantly higher expression in androgen-sensitive beard dermal papilla cells compared to androgen-insensitive scalp cells, suggesting potential novel signaling pathways in hair follicles.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This review discusses the role of complement activation in SLE and suggests that while monitoring C3 and C4 remains important, increased levels of cell-bound complement activation products may better indicate disease activity.

This letter reports a series of cases where the use of ruxolitinib at a lower dose than previously studied led to hair regrowth in patients with severe alopecia areata.

Spironolactone might help protect against severe lung problems in COVID-19 patients.

This study found that in Arabidopsis seedlings, tonoplast intrinsic proteins are targeted to the vacuole via at least two pathways, including pathways with differing sensitivity to a chemical inhibitor that affect root hair growth and PIN2 targeting.

This research suggests that targeting the HIF-1α pathway via PHD inhibitors may enable regeneration similar to amphibians in mammals, potentially fast-tracking regenerative therapies from mice to humans.

This study found that alkaloids isolated from Eclipta alba leaves showed increasing antimicrobial activity with higher concentrations, particularly against S. aureus and E. coli, suggesting potential for developing antimicrobial agents.

This review highlights that while dexamethasone may reduce mortality in severe COVID-19, no other drugs have proven effectiveness for treatment, emphasizing the need for clinical trials of existing medications.

This study suggests that deep dermatophytosis is a distinct condition occurring in immunocompromised patients, characterized by nodules, an indolent course, and absence of follicular invasion, which resolves completely with systemic antifungal treatment.

This study found that the receptor kinase RHS10 negatively regulates root hair growth in Arabidopsis thaliana by modulating growth duration and is associated with cell wall signal mediation, involving RNA catabolism and ROS accumulation.

This study reports that microencapsulation of therapeutic cells with contrast agents enables visualization across multiple imaging modalities, potentially improving cellular immunoprotection and tracking after transplantation.

This review compiles studies on the antidiabetic potential of plants from the Middle East, particularly from the Asteraceae and Lamiaceae families, but reports no clinical results.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This study found that different species metabolized minoxidil into various products, with monkeys and humans showing similar profiles primarily excreting a glucuronide conjugate, while rats and dogs showed distinct differences.

This study found that Merkel cell clusters require Frizzled6 signaling for their polarity information, while other hair follicle-associated structures align their orientation based on the hair follicle itself.

This study found that Wnt3a increased beta-catenin signaling and upregulated specific genes in cultured human dermal papilla cells, enhancing their response to PGE2 and potentially aiding hair growth.

This review classifies engineered nanomaterials by composition and application in biomedicine, highlighting diverse uses like regenerative medicine and potential occupational side effects, but reports no new clinical results.

This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

This study found that Sp6 overproduction in ameloblast-lineage cells increased cell proliferation and ameloblastin expression, suggesting that Sp6 promotes amelogenesis by inhibiting follistatin gene expression.

This study used bioinformatics to explore molecular differences in testicular and ovarian responses to SARS-CoV-2, identifying genes that could be associated with sex differences in infection outcomes.

This study found that Israeli patients with alopecia areata had a higher prevalence of comorbid conditions, including food allergies and chronic spontaneous urticaria, compared to matched controls.

In this randomized clinical trial, the authors reported that adipose-derived stem cell constituent extract topical solution increased hair density and thickness in patients with androgenetic alopecia over 16 weeks compared to placebo.

This review discusses various aspects of hair follicle biology and highlights unresolved questions and potential new research avenues, but presents no new experimental findings.
