Phosphorylated alpha-synuclein in Iba1-positive macrophages in the skin of patients with Parkinson's disease.

Ann Clin Transl Neurol 2022 Jun 24. Epub 2022 Jun 24.

Department of Neurology, National Hospital Organization Sendai Nishitaga Hospital, Sendai, Japan.

Background: Increasing evidence suggests that alpha-synuclein (αSyn) accumulation in cholinergic and adrenergic fibers in the skin is a useful biomarker to diagnose idiopathic Parkinson's disease (IPD). It has been widely reported that phosphorylated αSyn (p-αSyn) deposits in autonomic fibers in IPD are a biomarker in the skin, but other tissue localizations have not been fully investigated.

Objective: It has been previously suggested that αSyn aggregates activate peripheral macrophages and that peripheral macrophages ingest pathological αsyn aggregates in aged rats or IPD patients. Read More

Cutaneous Pharmacokinetic Approaches to Compare Bioavailability and/or Bioequivalence for Topical Drug Products.

Dermatol Clin 2022 Jul;40(3):319-332

10716 SE Forest View Lane, Happy Valley, OR 97086, USA.

The evaluation of bioequivalence (BE) involves comparing the test product to its reference product in a study whose fundamental scientific principles allow inferring of the clinical performance of the products. Several test methods have been discussed and developed to evaluate topical bioavailability (BA) and BE. Pharmacokinetics-based approaches characterize the rate and extent to which an active ingredient becomes available at or near its site of action in the skin. Read More

How Does the Food and Drug Administration Approve Topical Generic Drugs Applied to the Skin?

Dermatol Clin 2022 Jul 1;40(3):279-287. Epub 2022 Jun 1.

Office of Research and Standards, Office of Generic Drugs, US Food and Drug Administration, 10903 New Hampshire Avenue, Silver Spring, MD 20993, USA.

Approved generic drugs are therapeutically equivalent to a preidentified brand name product and are expected to have the same clinical effect and safety profile when administered to patients under conditions specified in the labeling. Availability of generic topical dermatologic drugs is expected to enhance patient access to such widely used drug products. Assessment of equivalence for a prospective generic product involves a systematic and rigorous comparative evaluation to ensure there is no significant difference in the rate and extent to which the active ingredients become available at the site of action for the prospective generic and corresponding brand name product.

Human organ rejuvenation by VEGF-A: Lessons from the skin.

Sci Adv 2022 Jun 24;8(25):eabm6756. Epub 2022 Jun 24.

Skin Research Laboratory, Rappaport Faculty of Medicine, Technion - Israel Institute of Technology, Haifa, Israel.

Transplanting aged human skin onto young SCID/beige mice morphologically rejuvenates the xenotransplants. This is accompanied by angiogenesis, epidermal repigmentation, and substantial improvements in key aging-associated biomarkers, including ß-galactosidase, p16, SIRT1, PGC1α, collagen 17A, and MMP1. Angiogenesis- and hypoxia-related pathways, namely, vascular endothelial growth factor A (VEGF-A) and HIF1A, are most up-regulated in rejuvenated human skin. Read More

Personalised pose estimation from single-plane moving fluoroscope images using deep convolutional neural networks.

PLoS One 2022 24;17(6):e0270596. Epub 2022 Jun 24.

Institute for Biomechanics, ETH Zürich, Zürich, Switzerland.

Measuring joint kinematics is a key requirement for a plethora of biomechanical research and applications. While x-ray based systems avoid the soft-tissue artefacts arising in skin-based measurement systems, extracting the object's pose (translation and rotation) from the x-ray images is a time-consuming and expensive task. Based on about 106'000 annotated images of knee implants, collected over the last decade with our moving fluoroscope during activities of daily living, we trained a deep-learning model to automatically estimate the 6D poses for the femoral and tibial implant components.

White patients' physical responses to healthcare treatments are influenced by provider race and gender.

Proc Natl Acad Sci U S A 2022 Jul 27;119(27):e2007717119. Epub 2022 Jun 27.

Department of Psychology, Stanford University, Stanford, CA 94305.

The healthcare workforce in the United States is becoming increasingly diverse, gradually shifting society away from the historical overrepresentation of White men among physicians. However, given the long-standing underrepresentation of people of color and women in the medical field, patients may still associate the concept of doctors with White men and may be physiologically less responsive to treatment administered by providers from other backgrounds. To investigate this, we varied the race and gender of the provider from which White patients received identical treatment for allergic reactions and measured patients' improvement in response to this treatment, thus isolating how a provider's demographic characteristics shape physical responses to healthcare.

Novel Complement C5 Small-interfering RNA Lipid Nanoparticle Prolongs Graft Survival in a Hypersensitized Rat Kidney Transplant Model.

Transplantation 2022 Jun 24. Epub 2022 Jun 24.

Department of Urology, Tokyo Women's Medical University, Shinjuku-ku, Tokyo, Japan.

Background: Prophylaxis of antibody-mediated rejection (AMR) caused by donor-specific antibodies remains challenging. Given the critical roles of complement activity in antibody-mediated graft injury, we developed a lipid nanoparticle (LNP) formulation of small-interfering RNA against complement C5 (C5 siRNA-LNP) and investigated whether C5 siRNA-LNP could downregulate the complement activity and act as an effective treatment for AMR.

Methods: Lewis recipient rats were sensitized by skin grafting from Brown Norway donor rats. Read More

Development and characterisation of an irradiation device for biomedical studies covering the solar spectrum with individual regulated spectral bands.

Photochem Photobiol Sci 2022 Jun 24. Epub 2022 Jun 24.

Cell Biology and Epigenetics, Department of Biology, Technical University of Darmstadt, Schnittspahnstr. 10, 64287, Darmstadt, Germany.

To understand the importance of terrestrial solar exposure on human skin, not only individual spectral components need to be considered in biomedical studies, but also the relevance of the combined action profile of the complete solar spectrum (cSS) must be established. We therefore developed a novel irradiation device that combines the emission of four individual lamps (UVB, UVA, VIS and nIR) to achieve exposure from 280 to 1400 nm with individual controllable lamps. The integrated irradiance of each spectral band is similar to the solar spectrum. Read More

Photoaging: UV radiation-induced inflammation and immunosuppression accelerate the aging process in the skin.

Inflamm Res 2022 Jun 24. Epub 2022 Jun 24.

School of Pharmacy, Faculty of Health Sciences, University of Eastern Finland, P.O. Box 1627, 70211, Kuopio, Finland.

Background: Excessive exposure of the skin to UV radiation (UVR) triggers a remodeling of the immune system and leads to the photoaging state which is reminiscent of chronological aging. Over 30 years ago, it was observed that UVR induced an immunosuppressive state which inhibited skin contact hypersensitivity.

Methods: Original and review articles encompassing inflammation and immunosuppression in the photoaging and chronological aging processes were examined from major databases including PubMed, Scopus, and Google Scholar. Read More
