Isotopic and molecular analyses of n-alkanes in a temporal study of coastal sediment contributions to organic carbon degradation induced by algal bloom and terrestrial runoff

Author(s): Mirzaei Y; Douglas PMJ; Gélinas Y;

The priming effect (PE) refers to the enhanced remineralization of recalcitrant organic carbon (OC) driven by the respiration of labile OC, potentially increasing CO2 fluxes from aquatic ecosystems. Patterns of PE induced by marine and terrestrial OC inputs can be explored through sedimentary contributions to the degraded OC pool. In this study, coastal s ...

Exploring the Qualitative Experiences of Administering and Participating in Remote Research via Telephone Using the Montreal Cognitive Assessment-Blind: Cross-Sectional Study of Older Adults

Author(s): Dumassais S; Grewal KS; Aubin G; O' Connell M; Phillips NA; Wittich W;

Background: The COVID-19 pandemic caused a drastic shift in the practice of research and clinical services. It has been noted that cognition measured via in-person versus remote methods differ substantially, and it is possible that subjective and experiential differences exist between modalities. Objective: The aim of the study is to explore the percepti ...

Reduction of Cr(VI) by Bacillus toyonensis LBA36 and its effect on radish seedlings under Cr(VI) stress

Author(s): Tan A; Wang H; Zhang H; Zhang L; Yao H; Chen Z;

Chromium, being among the most toxic heavy metals, continues to demand immediate attention in the remediation of Cr-contaminated environments. In this study, a strain of LBA36 (Bacillus toyonensis) was isolated from heavy metal contaminated soil in Luanchuan County, Luoyang City, China. The reduction and adsorption rates of LBA36 in 30 mg·L-1 Cr-containin ...

Emerging hazardous chemicals and biological pollutants in Canadian aquatic systems and remediation approaches: A comprehensive status report

Author(s): Adeola AO; Paramo L; Fuoco G; Naccache R;

Emerging contaminants can be natural or synthetic materials, as well as materials of a chemical, or biological origin; these materials are typically not controlled or monitored in the environment. Canada is home to nearly 7 % of the world's renewable water supply and a wide range of different kinds of water systems, including the Great Lake, rivers, c ...

Measurement invariance and differential item functioning of the functionality appreciation scale (FAS) in Colombia and Spain

Author(s): Mebarak M; Maïano C; Mendoza J; Zamora Á; Baños R; Desdentado L; Miragall M; Herrero R; Swami V;

The Functionality Appreciation Scale (FAS) is increasingly used in diverse national and linguistic contexts. However, limited work has assessed the extent to which the instrument demonstrates measurement invariance and differential item functioning (DIF) across nations and respondent characterist ...

NREM sleep brain networks modulate cognitive recovery from sleep deprivation

Author(s): Lee K; Wang Y; Cross NE; Jegou A; Razavipour F; Pomares FB; Perrault AA; Nguyen A; Aydin Ü; Uji M; Abdallah C; Anticevic A; Frauscher B; Benali H; Dang-Vu TT; Grova C;

Decrease in cognitive performance after sleep deprivation followed by recovery after sleep suggests its key role, and especially non-rapid eye movement (NREM) sleep, in the maintenance of cognition. It remains unknown whether brain network reorganization in NREM sleep stages N2 and N3 can uniquel ...

From wastewater to clean water: Recent advances on the removal of metronidazole, ciprofloxacin, and sulfamethoxazole antibiotics from water through adsorption and advanced oxidation processes (AOPs)

Author(s): Gahrouei AE; Vakili S; Zandifar A; Pourebrahimi S;

Antibiotics released into water sources pose significant risks to both human health and the environment. This comprehensive review meticulously examines the ecotoxicological impacts of three prevalent antibiotics-ciprofloxacin, metronidazole, and sulfamethoxazole-on the ecosystems. Within this framework, our primary focus revolves around the key remediati ...

Microbially Induced Calcium Carbonate Precipitation as a Bioremediation Technique for Mining Waste

Author(s): Wilcox SM; Mulligan CN; Neculita CM;

Mining waste represents a global issue due to its potential of generating acidic or alkaline leachate with high concentrations of metals and metalloids (metal(loid)s). Microbial-induced calcium carbonate precipitation (MICP) is an engineering tool used for remediation. MICP, induced via biological activity, aims to precipitate calcium carbonate (CaCO3) or ...

The impact of lesion side on bilateral upper limb coordination after stroke

Author(s): Shih PC; Steele CJ; Hoepfel D; Muffel T; Villringer A; Sehm B;

Background: A stroke frequently results in impaired performance of activities of daily life. Many of these are highly dependent on effective coordination between the two arms. In the context of bimanual movements, cyclic rhythmical bilateral arm coordination patterns can be classified into two fundamental modes: in-phase (bilateral homologous muscles cont ...
