Multiple functions of pyruvate kinase M2 in various cell types.

J Cell Physiol 2021 Jul 26. Epub 2021 Jul 26.

Department of Biochemistry, College of Medicine, Hallym University, Chuncheon, Republic of Korea.

Glucose metabolism is a mechanism by which energy is produced in form of adenosine triphosphate (ATP) by mitochondria and precursor metabolites are supplied to enable the ultimate enrichment of mature metabolites in the cell. Recently, glycolytic enzymes have been shown to have unconventional but important functions. Among these enzymes, pyruvate kinase M2 (PKM2) plays several roles including having conventional metabolic enzyme activity, and also being a transcriptional regulator and a protein kinase. Read More

Altered central and peripheral hemodynamics during rhythmic handgrip exercise in young adults with SARS-CoV-2.

Exp Physiol 2021 Jul 26. Epub 2021 Jul 26.

Department of Health & Exercise Science, Appalachian State University, Boone, NC.

New Findings: What is the central question of this study? This study sought to investigate whether central and peripheral hemodynamics during handgrip exercise were different in young adults 3-4 weeks following infection with of SARS-CoV-2 compared with young healthy adults. What is the main finding and its importance? The main findings are that exercising heart rate was higher while brachial artery blood flow and vascular conductance were lower in the SARS-CoV-2 compared with the control group. These findings provide evidence for peripheral impairments to exercise among adults with SARS-CoV-2, which may contribute to exercise limitations. Read More

Beijing Key Laboratory of Quality and Safety, Beijing Technology and Business University, Beijing 100048, China; Key Laboratory of Brewing Molecular Engineering of China Light Industry, Beijing Technology and Business University, Beijing 100048, China.

Liquid-liquid microextraction (LLME) combined with gas chromatography-olfactometry-mass spectrometry (GC-O-MS) was used to detect the variations in volatile compounds during the distillation process (head, heart, and tail) of raw Baijiu produced by different layers of fermented grains; 47 aroma compounds were sniffed and identified. Moreover, temperature-programmed headspace gas chromatography-ion mobility spectrometry (TP-HS-GC-IMS) was applied to characterize the Baijiu distillation process for the first time. The 3D fingerprint spectrum clearly showed a variation in volatile compounds from different distillation stages, and most compounds showed a downward trend. Read More

Sediment quality assessment combining chemical and biological (non)target analysis.

Aquat Toxicol 2021 Jun 8;238:105883. Epub 2021 Jun 8.

Risk Assessment Research Center, Korea Institute of Ocean Science and Technology, Geoje 53201, Republic of Korea; Department of Ocean Science, Korea University of Science and Technology, Daejeon 34113, Republic of Korea. Electronic address:

Aquatic sediments act as a storage for diverse mixtures of organic and inorganic contaminants. Nevertheless, most evaluations of contaminated sediments have been limited to the assessment of concentrations of target compounds and lethal effects on some test species. To identify the organic contaminants causing sub-lethal effects of contaminated sediment, this study combined chemical and biological (non)target analysis involving comprehensive two-dimensional gas chromatography coupled with a time-of-flight Mass Spectrometer (GCxGC/ToF-MS) analysis, embryonic malformation and high-throughput sequencing (RNA-seq) analysis on developing flounder.

Gut inference: A computational modelling approach.

Biol Psychol 2021 Jul 23:108152. Epub 2021 Jul 23.

Laureate Institute for Brain Research, Tulsa, OK, United States; Oxley College of Health Sciences, University of Tulsa, Tulsa, OK, United States. Electronic address:

Neurocomputational theories have hypothesized that Bayesian inference underlies interoception, which has become a topic of recent experimental work in heartbeat perception. To extend this approach beyond cardiac interoception, we describe the application of a Bayesian computational model to a recently developed gastrointestinal interoception task completed by 40 healthy individuals undergoing simultaneous electroencephalogram (EEG) and peripheral physiological recording. We first present results that support the validity of this modelling approach. Read More

Conserved and context-dependent roles for pdgfrb signaling during zebrafish vascular mural cell development.

Dev Biol 2021 Jul 23. Epub 2021 Jul 23.

Department of Molecular, Cell, and Cancer Biology, University of Massachusetts Medical School, Worcester, MA, 01650, United States. Electronic address:

Platelet derived growth factor beta and its receptor, Pdgfrb, play essential roles in the development of vascular mural cells, including pericytes and vascular smooth muscle cells. To determine if this role was conserved in zebrafish, we analyzed pdgfb and pdgfrb mutant lines. Similar to mouse, pdgfb and pdgfrb mutant zebrafish lack brain pericytes and exhibit anatomically selective loss of vascular smooth muscle coverage. Read More
