This review discusses the potential roles of calcium in the regulation of pluripotent and tissue-specific stem cells but reports no new experimental results, highlighting areas for future research.

This study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.

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

This study used Cisd2 knockout mice models and found that these mice display premature aging characteristics and an increase in dysfunctional neutrophils, suggesting Cisd2's role in calcium homeostasis and neutrophil function via interactions with Calnexin and SERCA.

In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.

This study found that several newly synthesized dihydrobenzopyran compounds inhibited insulin secretion and had vasorelaxant activity, with some more potent than reference KATP channel activators, though compound 21 functioned as a Ca2+ entry blocker.

This study identified a thiazolidine dione derivative as a potential inhibitor of 15-PGDH that may enhance prostaglandin activity in hair follicles, suggesting its use to support hair regrowth treatments.

In this report, researchers observed that a single treatment using a combination of hyperdiluted calcium hydroxylapatite, platelet-rich plasma, and hyaluronidase improved neck wrinkles and skin laxity in two patients, indicating preliminary evidence for the safety and efficacy of this novel therapy.

This study found that SK2 channels in sensory terminals of rat muscle spindles and hair follicles may play a crucial role in modulating mechanosensory transduction by influencing receptor potentials through Ca2+-activated K+ currents.

This review discusses the roles and mechanisms of chromatin remodelers and their subunits in mammalian development, but reports no new experimental results.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

This study found that the protein hairless acts as both a corepressor and coactivator of the vitamin D receptor, influencing gene transcription in a ligand-selective manner.

This study found that the loss of Smad4 in keratinocytes reduces Dsg4 expression via disrupted BMP signaling, contributing to hair follicle degeneration and alopecia.

This study found that in mice, knockout of Rac1 and Rac3 in keratinocytes led to reduced white adipose tissue and revealed Rac-dependent paracrine pathways affecting pre-adipocyte differentiation.

This study found that Secretory Phospholipase A2-IIA (sPLA2-IIA) promotes proliferation through JNK/c-Jun signaling, distinctively affecting normal stem cells and cancer cells, suggesting it as a potential target for cancer treatment.

This study reported significantly lower levels of serum iron, ferritin, and calcium in young patients with premature gray hair compared to controls, implying that supplementation might prevent further graying.

This study found trilostane to be an effective and generally safe treatment for improving symptoms in dogs with pituitary-dependent hyperadrenocorticism.

This study found that NGAL expression increased in calcium-induced keratinocyte differentiation in vitro and was highly elevated in psoriasis-like skin conditions and skin cancers, suggesting a role in skin hyperplasia and homeostasis.

This study found that patients with alopecia areata had significantly lower serum vitamin D levels and higher odds of vitamin D deficiency, but no significant difference in serum calcium levels, compared to controls.

The authors concluded that controlling voltage, pulse width, and calcium concentration in pulse electric field-activated platelet-rich plasma enhances the release of growth factors and serotonin without causing clot formation, suggesting potential clinical advantages over bovine thrombin-activated PRP.

This study found that HDAC6 plays a crucial role in regulating primordial follicle activation, with its overexpression delaying activation and preserving fertility by reducing NGF levels.

This study found that pharmacological inhibition of sex steroid synthesis impacts pathogenic processes in traumatic brain injury in a sex-specific manner, with distinct effects of letrozole and finasteride on molecular and neurological outcomes.

This study found that c-Jun is essential for vitamin D receptor expression, and the vitamin D receptor inhibits c-Jun-dependent cell death through non-classical mechanisms independent of vitamin D3.

In this study, low-level laser therapy significantly improved the mechanical strength of bone at tooth extraction sites in rats, while neither platelet-rich plasma alone nor combined with laser affected mechanical strength or calcium content.

This review discusses U.S. patents in organic process development published in July and August 2004 and reports no new experimental results.

This case study reported that absence of alopecia does not reliably predict responsiveness to vitamin D treatment in Vitamin D-dependent rickets type II, as demonstrated by a patient with normal hair growth who showed extreme resistance.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

This study found that while autonomous Sema3A expression limited keratinocyte migration and delayed wound healing, non-autonomous application of recombinant Sema3A with EGF enhanced wound repair in mice.

This article updates the process of care model for evaluating erectile dysfunction, emphasizing comprehensive evaluation and a combination of pharmacotherapy and counseling tailored to patient dynamics.

This article presents guidelines developed by a multidisciplinary expert panel for the care of adolescent transgender and non-binary individuals with gender dysphoria, emphasizing individualized, affirmative care to enhance well-being and quality of life.
