Tandem osmotic engine based on hydrogel particles with antipolyelectrolyte and polyelectrolyte effect fuelled by both salinity gradient modes
Published 2021“…The energy recovery from the tandem engine setup (calculated based on dry form for each polyelectrolyte polyacrylate-based hydrogel-SPA) and antipolyelectrolyte– sulfobetaine-based gel with methacrylate polymeric backbone-SBE) up to 581 J kg−1 and a mean power of 0.16 W kg−1 was obtained by the tandem setup of SPA and SBE hydrogel containing 3% crosslinking density and particle size of 500 microns with an external load of 3.0 kPa. Exchange of sulfobetaine with methacrylamide (SBAm), the main polymer backbone, revealed a positive increase in energy recovery of 670 J kg−1 with a mean power of 0.19 W kg−1 for the tandem system operating under the same parameters (SPA@SBAm). …”

Understanding the mechanisms mediating cardio-renal benefit of empagliflozin in type 2 diabetes mellitus
Published 2023“…They have demonstrated1 that empagliflozin treatment resulted in a significant decrease in pulse pressure (PP), mean arterial pressure (MAP) and cardiac workload, compared with placebo; at week 12, placebo-adjusted mean changes from baseline were − 2.5 mmHg for PP, − 2.2 mmHg for MAP and − 315 mmHg x beats per minute (bpm) for cardiac workload (p < 0.0001 for all). …”

EPIDEMIOLOGY OF CHLAMYDIA TRACHOMATIS IN LATIN AMERICA AND THE CARIBBEAN: SYSTEMATIC REVIEW, META-ANALYSES, AND META-REGRESSIONS
Published 2022“…We conducted random-effects meta-regressions to identify sources of heterogeneity and possible predictors of high prevalence. Results: The pooled-mean urogenital CT prevalence was 8.2% (95% CI: 7.5-9.1) for general populations, 14.0% (95%CI: 12.7-15.4) for female sex workers, 10.8% (95% CI: 8.4-13.4) for men who have sex with men, male sex workers, and transgenders, 16.1% (95% CI: 12.6-19.8) for symptomatic women, 25.4 (95% CI: 18.6-38.5) for symptomatic men, 9.7% (95%CI: 6.1-14) for HIV-positive individuals and individuals in HIV-discordant couples, and 11.9% (95 CI: 8.5-15.8) for STI clinic attendees. …”
