Photobiomodulation for the management of alopecia: mechanisms of action, patient selection and perspectives.

Photobiomodulation for the management of alopecia: mechanisms of action, patient selection and perspectives. Clin Cosmet Investig Dermatol. 2019;12:669-678 Authors: Hamblin MR Abstract Photobiomodulation (PBM) or low-level laser therapy was discovered over 50 years ago, when Mester in Hungary observed regrowth of hair in mice when irradiated with a ruby laser. At the present time, several different PBM devices are marketed to assist with hair regrowth in alopecia patients. This review covers the three main types of alopecia (androgenetic, areata, and chemotherapy-induced), and discusses the mechanism of action of PBM for each disease. The different devices used (mostly low powered red laser diodes), dosimetry, animal models, and clinical trials are summarized. Criteria for patient selection are outlined. Finally a perspectives section looks forward to the future. PMID: 31686888 [PubMed]

Aspects concerning patient adherence to anti-TNFα therapy in psoriasis: A decade of clinical experience. Exp Ther Med. 2019 Dec;18(6):4987-4992 Authors: Mocanu M, Toader MP, Rezus E, Taranu T Abstract Non-adherence to psoriasis treatment has an important impact in controlling chronic disease evolution and the occurrence of systemic comorbidities. Biologic therapy represents a revolutionary treatment, many of the undesirable psychological and socio-economical consequences of conventional topical or systemic therapies being avoided. Nevertheless, the discontinuation of biological therapy may occur ...

AbstractNowadays, there is a great attention to the plasma applications in medicine. Not only does cold atmospheric pressure plasma provide a therapeutic opportunity to control redox-based processes, it is also an innovative method in rejuvenation. Given the current interest in new methods of rejuvenation, we aimed to introduce a novel pulsed nitrogen plasma torch with potential use in rejuvenation. We investigated production of reactive species at different  pulse energy by spectroscopy and also measured nitric oxide and O2 concentration and evaluated the flame temperature. Fifteen Wistar rats were divided into three...

Upon binding to pathogen or self-derived cytosolic nucleic acids cyclic GMP-AMP synthase (cGAS) triggers the production of cGAMP that further activates transmembrane protein STING. Upon activation STING translocates from ER via Golgi to vesicles. Monogenic STING gain-of-function mutations cause early-onset type I interferonopathy, with disease presentation ranging from fatal vasculopathy to mild chilblain lupus. Molecular mechanisms underlying the variable phenotype-genotype correlation are presently unclear. Here, we report a novel gain-of-function G207E STING mutation causing a distinct phenotype with alopecia, photosens...

In this study, we designed to induce platelets in PRP to release factors by calcium chloride (PC) or by sonication where platelet lysates (PS) or the supernatants of platelet lysate (PSS) were used to evaluate their effect on the hair follicle activation and regeneration. We found that PSS and PS exhibited a superior effect in activating telogen hair follicles than PC. In addition, PSS injection into the skin activated quiescent hair follicles and induced K15+ hair follicle stem cell proliferation in K14-H2B-GFP mice. Moreover, PSS promoted skin-derived precursor (SKP) survival in vitro and enhanced hair follicle formation...

CONCLUSIONS: Overall, this study shows that methotrexate for paediatric AA in an Australian context was beneficial for the majority of cases assessed and had minimal adverse effects. We propose that such treatment should not be ruled out in the paediatric population. PMID: 31802478 [PubMed - as supplied by publisher]
