Bioresour Technol 2021 Apr 7;332:125119. Epub 2021 Apr 7.

Laboratory of Environment-Enhancing Energy (E2E), Key Laboratory of Agricultural Engineering in Structure and Environment, Ministry of Agriculture, College of Water Resources and Civil Engineering, China Agricultural University, Beijing 100083, China. Electronic address:

Microbial stability and evolution are a critical aspect for biosensors, especially in detecting dynamic and emerging anaerobic biohythane production. In this study, two upflow air-cathode chamber microbial fuel cells (UMFCs) were developed for in situ monitoring of the biohydrogen and biomethane reactors under a COD range of 1000-6000 mg/L and 150-1000 mg/L, respectively. Illumina MiSeq sequencing evidenced the dramatic shift of dominant microbial communities in UMFCs from hydrolytic and acidification bacteria (Clostridiaceae_1, Ruminococcaceae, Peptostreptococcaceae) to acetate-oxidizing bacteria (Synergistaceae, Dysgonomonadaceae, Spirochaetaceae).

ANGIOTENSIN RECEPTOR BLOCKERS AND ANGIOTENSIN CONVERTING ENZYME INHIBITORS IN COVID-19 -META-ANALYSIS/META-REGRESSION ADJUSTED FOR CONFOUNDING FACTORS.

CJC Open 2021 Apr 6. Epub 2021 Apr 6.

Centre for Heart Lung Innovation, St. Paul's Hospital, University of British Columbia, Vancouver, BC, Canada.

Background: Angiotensin receptor blockers (ARBs) and/or angiotensin converting enzyme (ACE) inhibitors could alter mortality of COVID-19, but existing meta-analyses which combined crude and adjusted results may be confounded by comorbidities being more common in ARBs/ACE inhibitors users.

Methods: We searched PubMed/MEDLINE/Embase for cohort studies and meta-analysis reporting mortality by pre-existing ARB/ACE inhibitor treatment in hospitalized COVID-19 patients. Random effects meta-regression was used to compute pooled odds ratios for mortality adjusted for imbalance in age, sex and prevalence of cardiovascular disease, hypertension, diabetes mellitus and chronic kidney disease between users and non-users of ARBs/ACE inhibitors at the study-level during data synthesis.

School of Electrical and Electronics Engineering, College of ICT Engineering, Chung-Ang University, Seoul, Republic of Korea.

Optical coherence tomography (OCT) is a three-dimensional (3-D) optical imaging technology that provides noninvasive, micrometer resolution images of structural interiors within biological samples with an approximately 1 ~ 2 mm penetration depth. Over the last decades, advances in OCT have revolutionized biomedical imaging by demonstrating a potential of optical biopsy in preclinical and clinical settings. Recently, functional OCT imaging has shown a promise as angiography to visualize cell-perfused vasculatures in the tissue bed in vivo without requiring any exogenous contrast agents. Read More
