Sofpironium bromide (ECCLOCK® in Japan) gel is a topical anticholinergic agent developed by Bodor Laboratories and licenced to Brickell Biotech for the treatment of hyperhidrosis. The drug is designed to reduce sweating by inhibiting M3 muscarinic receptors in eccrine glands at the application site. In September 2020, sofpironium bromide gel 5% received its first approval in Japan for the treatment of primary axillary hyperhidrosis (PAH). Clinical studies are currently ongoing in the USA to assess the safety and efficacy of sofpironium bromide gel 15% in PAH. This article summarizes the milestones in the development of sofpironium bromide gel leading to this first approval for the treatment of PAH.
Identifying and understanding modifiable risk and protective factors that can inform early detection and intervention to prevent adolescent emotional problems and harmful behaviours is among the most pressing modern-day public health challenges. This paper describes the rationale, objectives, methods, and anticipated outcomes of the LIFECOURSE study, a multi-level, bio-psychosocial prospective study designed to advance our understanding of factors that shape adolescent mental health and behaviour.

Conducted by the Icelandic Centre for Social Research and Analysis at Reykjavik University, LIFECOURSE is a longitudinal population-based developmental study of Icelandic adolescents born in 2004. The study utilizes a comprehensive multi-informant assessment of individual, societal and biological factors measured across the lifespan. Data assembly and collection were conducted from 2016-2020 and utilize both retrospective and prospective data sources (a) retrospective registry data assembled from seven national RSE study was designed to address this knowledge gap.Senescent cells are growth-arrested cells that cause inflammation and play a causal role in aging. They accumulate with age, and preventing this accumulation delays age-related diseases. LY364947 solubility dmso However, the mechanism for senescent cell accumulation is not fully understood. Accumulation can result from increasing production or decreasing removal of senescent cells with age, or both. To distinguish between these possibilities, we analyze data from parabiosis, the surgical conjoining of two mice so that they share circulation. Parabiosis between a young and old mouse, called heterochronic parabiosis, reduces senescent cell levels in the old mouse, while raising senescent cell levels in the young mouse. We show that parabiosis data can reject mechanisms for senescent cell accumulation in which only production rises with age or only removal decreases with age; both must vary with age. Since removal drops with age, senescent cell half-life rises with age. This matches a recent model for senescent cell accumulation developed from independent data on senescent cell dynamics, called the SR model, in which production rises linearly with age and senescent cells inhibit their own removal. The SR model further explains the timescales and mechanism of rejuvenation in parabiosis, based on transfer of spare removal capacity from the young mouse to the old. The present quantitative understanding can help design optimal treatments that remove senescent cells, by matching the time between treatments to the time it takes senescent cells to re-accumulate.The capacity to move is essential for independence and declines with age. Slow movement speed, in particular, is strongly associated with negative health outcomes. Prior research on mobility (herein defined as movement slowness) and aging has largely focused on musculoskeletal mechanisms and processes. More recent work has provided growing evidence for a significant role of the nervous system in contributing to reduced mobility in older adults. In this article, we report four pieces of complementary evidence from behavioral, genetic, and neuroimaging experiments that, we believe, provide theoretical support for the assertion that the basal ganglia and its dopaminergic function are responsible, in part, for age-related reductions in mobility. We report four a posteriori findings from an existing dataset (1) slower central activation of ballistic force development is associated with worse mobility among older adults; (2) older adults with the Val/Met intermediate catecholamine-O-methyl-transferase (COMT) genotype involved in dopamine degradation exhibit greater mobility than their homozygous counterparts; (3) there are moderate relationships between performance times from a series of lower and upper extremity tasks supporting the notion that movement speed in older adults is a trait-like attribute; and (4) there is a relationship of functional connectivity within the medial orbofrontal (mOFC) cortico-striatal network and measures of mobility, suggesting that a potential neural mechanism for impaired mobility with aging is the deterioration of the integrity of key regions within the mOFC cortico-striatal network. These findings align with recent basic and clinical science work suggesting that the basal ganglia and its dopaminergic function are mechanistically linked to age-related reductions in mobility capacity.Morita-Baylis-Hillman adducts (MBHA) are synthetic molecules with several biological actions already described in the literature. It has been previously described that adduct 2-(3-hydroxy-2-oxoindolin-3-yl)acrylonitrile (ISACN) has anticancer potential in leukemic cells. Inflammation is often associated with the development and progression of cancer. Therefore, to better understand the effect of ISACN, this study aimed to evaluate the anti-inflammatory potential of ISACN both in vitro and in vivo. Results demonstrated that ISACN negatively modulated the production of inflammatory cytokines IL-1β, TNF-α, and IL-6 by cultured macrophages. In vivo, ISACN 6 and 24 mg/kg treatment promoted reduced leukocyte migration, especially neutrophils, to the peritoneal cavity of zymosan-challenged animals. ISACN displays no anti-edematogenic activity, but it was able to promote a significant reduction in the production of inflammatory cytokines in the peritoneal cavity. These data show, for the first time, that MBHA ISACN negatively modulates several aspects of the inflammatory response, such as cell migration and cytokine production in vivo and in vitro, thus having an anti-inflammatory potential.
