Background: Dichloroacetate (DCA) has shown potential in modulating cellular metabolism and inflammation, particularly in cardiac conditions. This study investigates DCA's protective effects in a mouse model of myocardial infarction (MI), focusing on its ability to enhance cardiac function, reduce inflammation, and shift macrophage polarization from the pro-inflammatory M1 to the anti-inflammatory M2 phenotype.
Methods: An acute MI model was created using left anterior descending coronary artery ligation.

Pyroptosis and macrophage pro-inflammatory activation play an important role in hepatocellular carcinoma (HCC) progression. However, the specific regulatory mechanisms remain unclear. We identified pyroptosis-related differentially expressed genes (DEGs) based on the GSE4183 and GSE44861 datasets as well as EVenn database.

Hyperpolarized-C magnetic resonance imaging (HP-C MRI) was used to image changes in C-lactate signal during a visual stimulus condition in comparison to an eyes-closed control condition. Whole-brain C-pyruvate, C-lactate and C-bicarbonate production was imaged in healthy volunteers (N = 6, ages 24-33) for the two conditions using two separate hyperpolarized C-pyruvate injections. BOLD-fMRI scans were used to delineate regions of functional activation.

This work aims to determine the mechanism of the photomechanical response of poly(Methyl methacrylate) polymer doped with the photo-isomerizable dye Disperse Red 1 using the non-isomerizable dye Disperse Orange 11 as a control to isolate photoisomerization. Samples are free-standing thin films with thickness that is small compared with the optical skin depth to assure uniform illumination and photomechanical response throughout their volume, which differentiates these studies from most others. Polarization-dependent measurements of the photomechanical stress response are used to deconvolute the contributions of angular hole burning, molecular reorientation and photothermal heating.

is the specific pathogen for "milky disease" in the Chinese mitten crab (), accounting for huge losses to the industry. And yet, there is no precise study describing the pathogenesis of , largely hindering the development of novel control methods against its causing diseases. Here, we compared the transcriptomes of cells collected from a control group (cultured without hemocytes) and a treatment group (cultured with hemocytes), using RNA sequencing.
