Choline kinase alpha regulates autophagy-associated exosome release to promote glioma cell progression.

Glioma is the most common primary intracranial malignant tumor in adults, with a poor prognosis. Exosomes released by tumor cells play a crucial role in tumor development, metastasis, angiogenesis, and other biological processes. Despite this significance, the precise molecular mechanisms governing exosome secretion and their impact on tumor progression remain incompletely understood.

Calcium Ion Attenuates Transforming Growth Factor β1-Induced Extracellular Matrix Accumulation by Inducing Smad2 Degradation through the Proteasome Pathway.

Extracellular Ca is the first ligand that has been confirmed to function by activating the calcium-sensing receptor (CaSR), a member of G-protein coupled receptors. CaSR controls not only calcium homeostasis, but also plays a pivotal role in many cellular processes such as cell proliferation and apoptosis; moreover, it is implicated in the development of cardiovascular diseases. TGF-β/Smads signaling pathway is a classical pathway of renal fibrosis.

Near Real-Time Measurement of Airborne Carbon Nanotubes with Metals Using Raman-Spark Emission Spectroscopy.

We present a near real-time measurement method that combines Raman and spark emission spectroscopy to quantitatively analyze the molecular structure of airborne single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs), as well as detect toxic metals within CNTs. A corona-based aerosol microconcentrator was used for airborne CNTs sampling to enhance the measurement accuracy and sensitivity. The intensity of the characteristic Raman bands of CNTs and atomic emission lines of metals exhibited a linear relationship with the analyte mass, yielding high coefficient values.

The abiologically and biologically driving effects on organic matter in marginal seas revealed by deep learning-assisted model analysis.

The biogeochemical processes of organic matter exhibit notable variability and unpredictability in marginal seas.

The concentration of particulate organic carbon (POC) was determined to characterize the status of POM, and the fractions and fluorescent properties of DOM were identified through 3D excitation-emission-matrix spectra (3D-EEM) combined parallel factor analysis (PARAFAC).

Characterization of glycogen-related glycoside hydrolase and from and their roles in biofilm formation and virulence.

Glycogen is a polymer used by bacteria to store excess glucose, playing a crucial role in bacterial growth, stress resistance, biofilm formation, and virulence. In bacteria, the glycoside hydrolase family 13 protein are involved in the synthesis and metabolism of glycogen, respectively. The absence of these enzymes leads to changes in bacterial glycogen content, thereby affecting the growth metabolism of the strain.

Correlations of the triglyceride-glucose index and modified indices with arterial stiffness in overweight or obese adults.

Background: Insulin resistance (IR) contributes substantially to the development of cardiovascular disease (CVD) and metabolic disorders, particularly obesity. The homeostatic model assessment of IR is a prevalent IR indicator, but insulin measurement is quite impractical for widely use. Given its convenience and accessibility, the triglyceride-glucose (TyG) index, along with modified indices such as the triglyceride-glucose-waist circumference (TyG-WC) and triglyceride-glucose-waist-height ratio (TyG-WHtR), are gaining recognition as practical tools for assessing IR.
