Stress Changes the Bacterial Biomolecular Condensate Material State and Shifts Function from mRNA Decay to Storage.

Bacterial ribonucleoprotein bodies (BR-bodies) are dynamic biomolecular condensates that play a pivotal role in RNA metabolism. We investigated how BR-bodies significantly influence mRNA fate by transitioning between liquid- and solid-like states in response to stress. With a combination of single-molecule and bulk fluorescence microscopy, biochemical assays, and quantitative analyses, we determine that BR-bodies promote efficient mRNA decay in a liquid-like condensate during exponential growth.

Super-resolution microscopy unveils the nanoscale organization and self-limiting clustering of CD47 in human erythrocytes.

The transmembrane protein CD47, an innate immune checkpoint protein, plays a pivotal role in preventing healthy erythrocytes from immune clearance. Our study utilized stochastic optical-reconstruction microscopy (STORM) and single-molecule analysis to investigate the distribution of CD47 on the human erythrocyte membrane. Contrary to previous findings in mouse erythrocytes, we discovered that CD47 exists in randomly distributed monomers rather than in clusters across the human erythrocyte membrane.

Manipulated C5aR1 over/down-expression associates with IL-6 expression during bacterial inflammation in half-smooth tongue sole (Cynoglossus semilaevis).

The complement component 5a/complement component 5 receptor 1 (C5a/C5aR1) pathway plays a crucial role in the onset and development of inflammation, but relevant studies in fish are lacking. In this study, we successfully characterized the relationship between half-smooth tongue sole (Cynoglossus semilaevis) C5aR1 (CsC5aR1) and bacterial inflammation. First, we showed that the overexpression of CsC5aR1 significantly increased bacterial pathological damage in the liver and intestine, whereas inhibition attenuated the damage.

Inhaled nitric oxide: can it serve as a savior for COVID-19 and related respiratory and cardiovascular diseases?

Nitric oxide (NO), as an important gaseous medium, plays a pivotal role in the human body, such as maintaining vascular homeostasis, regulating immune-inflammatory responses, inhibiting platelet aggregation, and inhibiting leukocyte adhesion. In recent years, the rapid prevalence of coronavirus disease 2019 (COVID-19) has greatly affected the daily lives and physical and mental health of people all over the world, and the therapeutic efficacy and resuscitation strategies for critically ill patients need to be further improved and perfected. Inhaled nitric oxide (iNO) is a selective pulmonary vasodilator, and some studies have demonstrated its potential therapeutic use for COVID-19, severe respiratory distress syndrome, pulmonary infections, and pulmonary hypertension.

COVID-19 and the cardiovascular system: a study of pathophysiology and interpopulation variability.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in humans can lead to various degrees of tissue and organ damage, of which cardiovascular system diseases are one of the main manifestations, such as myocarditis, myocardial infarction, and arrhythmia, which threaten the infected population worldwide. These diseases threaten the cardiovascular health of infected populations worldwide. Although the prevalence of coronavirus disease 2019 (COVID-19) has slightly improved with virus mutation and population vaccination, chronic infection, post-infection sequelae, and post-infection severe disease patients still exist, and it is still relevant to study the mechanisms linking COVID-19 to cardiovascular disease (CVD).

Does deception involve more cognitive control than truth-telling? Meta-analyses of N2 and MFN ERP studies.

A number of psychological theories propose that deception involves more cognitive control than truth-telling. Over the last decades, event-related potentials (ERPs) have been used to unravel this question, but the findings are mixed. To address this controversy, two meta-analyses were conducted to quantify the results of existing studies reporting N2 or medial frontal negativity (MFN) associated with deception.

Effect of low temperature extrusion-modified potato starch addition on properties of whole wheat dough and texture of whole wheat youtiao.

In this study, low temperature extrusion-modified potato starch (MPS) was added to improve properties of whole wheat dough and textural quality of resulted youtiao. Extrusion temperature (60, 90 ℃) and barrel moisture content (30, 42 and 54%) were set as test variables. The results suggested that the low temperature extrusion processing caused moderate gelatinization and improved gel-forming properties of potato starch.

Effects of Jet Milling on the Physicochemical Properties of Buckwheat Flour and the Quality Characteristics of Extruded Whole Buckwheat Noodles.

The effects of jet milling on the physicochemical properties of buckwheat flour and the quality characteristics of extruded whole buckwheat noodles (WBN) were investigated in this study. The results reveal that the application of jet milling significantly reduced the particle size of buckwheat flour. As a result, the damaged starch content, water solubility index, water absorption index and swelling power of buckwheat flour all increased.

Belief or disbelief in feedback influences the detection efficiency of the feedback concealed information test.

The feedback concealed information test (fCIT) is a new variant of the CIT that added feedback about participants' concealing performances in the classical CIT. The advantage of the fCIT is that the resulting feedback related event-related potentials (ERPs) can be used to detect concealed information. However, the detection efficiency of feedback-based ERPs varies across studies.

Sex- and body mass index-specific reference intervals for serum leptin: a population based study in China.

Background: Leptin is a peptide hormone secreted by adipose tissue and is an important determinant of obesity and its complications. The purpose of this study was to establish sex- and body mass index (BMI)-specific reference intervals for serum leptin in a Chinese population and investigate the factors influencing leptin concentrations.

Methods: Fasting serum leptin levels were assayed in 469 men and 773 women from randomly sampled Chinese residents.

Effect of colchicine on inflammatory markers in patients with coronary artery disease: A meta-analysis of clinical trials.

Whether colchicine reduces the levels of high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) remains uncertain. Therefore, this systematic review and meta-analysis were conducted to evaluate the overall effect of colchicine treatment on hs-CRP and IL-6 levels in patients with coronary artery disease (CAD). PubMed/Medline, Embase, and the Cochrane Central Register of Controlled Trials were searched for studies published before October 2021.

The effect of mental countermeasures on a novel brain-based feedback concealed information test.

The feedback concealed information test (fCIT) is a novel form of the CIT, providing participants with feedback regarding their memory concealment performance. The fCIT utilizes event-related potentials (recognition-P300 and feedback-related event-related potentials) and has been shown to provide high efficiency in detecting information concealment. However, it is unclear how well the fCIT performs in the presence of mental countermeasures.

The Determination of Step Frequency in 3-min Incremental Step-in-Place Tests for Predicting Maximal Oxygen Uptake from Heart Rate Response in Taiwanese Adults.

Gene expression profile-based drug screen identifies SAHA as a novel treatment for NAFLD.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. Being part of the metabolic syndrome, NAFLD is characterized by the deposition of triglycerides (TGs) as lipid droplets in the cytoplasm of hepatic cells. Recently, the rapid development of high-throughput genome analysis technologies provided opportunities to screen for new drugs for NAFLD.
