Sorptive and microbial riddance of micro-pollutant ibuprofen from contaminated water: A state of the art review.

Sci Total Environ 2021 May 1;786:147327. Epub 2021 May 1.

Department of Chemical Engineering, National Institute of Technology Durgapur, India. Electronic address:

Continuous discharge of ibuprofen, a pharmaceutical compound in local water systems is becoming a budding concern as seen from data procured from the past few decades. Increased concentrations of the compound in water reservoirs resulted in adverse effects on the environment. In order to prevent the deleterious impacts of increasing ibuprofen concentration in water bodies, application of cost effective and energy efficient elimination of ibuprofen (IBP) is needed.

Influence of pregabalin maintenance on cannabis effects and related behaviors in daily cannabis users.

Exp Clin Psychopharmacol 2021 May 13. Epub 2021 May 13.

Department of Biostatistics.

No medications are approved for cannabis use disorder (CUD), though a small clinical trial demonstrated that the voltage-dependent calcium channel (VDCC) ligand gabapentin reduced cannabis use in treatment seekers. VDCCs are modulated by cannabinoid (CB) ligands, and there are shared effects between CB agonists and VDCC ligands. This overlapping neuropharmacology and the initial clinical results supported the evaluation of pregabalin, a "next-generation" VDCC ligand, as a CUD medication. Read More

The Prevalence of in Hard Ticks in Europe and Their Role in Q Fever Transmission Revisited-A Systematic Review.

Front Vet Sci 2021 26;8:655715. Epub 2021 Apr 26.

Institute of Bacterial Infections and Zoonoses (IBIZ), Friedrich-Loeffler-Institute, Federal Research Institute for Animal Health, Jena, Germany.

The zoonosis Q fever is caused by the obligate intracellular bacterium . Besides the main transmission route inhalation of contaminated aerosols, ticks are discussed as vectors since the first isolation of the pathogen from a tick. The rare detection of in ticks and the difficult differentiation of from -like endosymbionts (CLEs) are questioning the relevance of ticks in the epidemiology of Q fever. Read More

Evaluation of 24-h screen deployments as a standardized platform to monitor Gambierdiscus populations in the Florida Keys and U.S. Virgin Islands.

Harmful Algae 2021 Mar 13;103:101998. Epub 2021 Feb 13.

Biology Department, MS #32, Woods Hole Oceanographic Institution, Woods Hole, MA 02543, USA.

Anchored mesh screens have been suggested as a standardized approach to monitor the cell abundances of epiphytic dinoflagellates in benthic habitats, including toxigenic members of the Gambierdiscus genus responsible for ciguatera poisoning (CP). Here we deployed screens for 24h at eight sites in the Florida Keys and St. Thomas (US Virgin Islands) to evaluate their performance relative to the traditional method of assessing Gambierdiscus abundance in which cell counts are normalized to wet weight of host algae.

Gender stigma awareness is associated with adolescent risky health behaviors.

PLoS One 2021 12;16(5):e0251332. Epub 2021 May 12.

Department of Pediatrics, David Geffen School of Medicine at UCLA, Los Angeles, California, United States of America.

Objectives: Although racial stigma in school is associated with adolescent risky health behaviors, there are no studies investigating how gender stigma relates to adolescent risky health behaviors among low-income, minority youth. We sought to determine whether gender stigma awareness is associated with adolescent risky health behaviors (delinquency, fighting, and substance use) and whether this association is mediated by school disengagement (low perceived teacher support, low school engagement, cutting classes, and breaking school rules) among low-income, minority students.

Methods: We analyzed cross-sectional survey data, collected from 2017 to 2019, from 412 high school students. Read More

The living heart: Climate gradients predict desert mountain endemism.

Ecol Evol 2021 May 15;11(9):4366-4378. Epub 2021 Mar 15.

Environmental Futures Research Institute and School of Environment and Science Griffith University Nathan Qld Australia.

Mountain regions are centers of biodiversity endemism at a global scale but the role of arid-zone mountain ranges in shaping biodiversity patterns is poorly understood. Focusing on three guilds of taxa from a desert upland refugium in Australia, we sought to determine: (a) the relative extent to which climate, terrain or geological substrate predict endemism, and (b) whether patterns of endemism are complimentary across broad taxonomic guilds. We mapped regional endemism for plants, land snails, and vertebrates using combined Species Distribution Models (SDMs) for all endemic taxa ( = 82). Read More

Unexpected acceleration of Ultrasonic-Assisted iodide dosimetry in the catalytic presence of ionic liquids.

Ultrason Sonochem 2021 Apr 25;74:105576. Epub 2021 Apr 25.

LRP UMR 5520, Université de Savoie Mont-Blanc, 73000 Chambéry, France.

This study investigates the potential of using small amounts of ionic liquids (IL) to enhance ultrasound-assisted extraction of lipids content from green microalgae. Three imidazolium-based ILs (butyl, octyl and dodecyl), each of them with two anions (bromide and acetate) were tested as additives. Viscosity and surface tension of the ILs aqueous mixtures were analyzed to determine the influence of ILs' anions and alkyl chain length, whereas KI dosimetry experiments were used as an indicator of radicals formation.

A New Assessment of Bicycle Helmets: The Brain Injury Mitigation Effects of New Technologies in Oblique Impacts.

Ann Biomed Eng 2021 May 10. Epub 2021 May 10.

Dyson School of Design Engineering, Imperial College, London, UK.

New helmet technologies have been developed to improve the mitigation of traumatic brain injury (TBI) in bicycle accidents. However, their effectiveness under oblique impacts, which produce more strains in the brain in comparison with vertical impacts adopted by helmet standards, is still unclear. Here we used a new method to assess the brain injury prevention effects of 27 bicycle helmets in oblique impacts, including helmets fitted with a friction-reducing layer (MIPS), a shearing pad (SPIN), a wavy cellular liner (WaveCel), an airbag helmet (Hövding) and a number of conventional helmets.

Clinically Approximated Hypoperfused Tissue in Large Vessel Occlusion Stroke.

Stroke 2021 May 11:STROKEAHA120033294. Epub 2021 May 11.

Department of Neurology, University of Pittsburgh Medical Center, PA. (S.M.D., A.P.J.).

Background And Purpose: Patient selection for thrombectomy of acute ischemic stroke caused by large vessel occlusion in the delayed time window (>6 hours) is dependent on delineation of clinical-core mismatch or radiological target mismatch using perfusion imaging. Selection paradigms not involving advanced imaging and software processing may reduce time to treatment and broaden eligibility. We aim to develop a conversion factor to approximately determine the volume of hypoperfused tissue using the National Institutes of Health Stroke Scale (NIHSS) score (clinically approximated hypoperfused tissue [CAT] volume) and explore its ability to identify patients eligible for thrombectomy in the late-time window.
