miR-124 Suppresses Pancreatic Ductal Adenocarcinoma Growth by Regulating Monocarboxylate Transporter 1-Mediated Cancer Lactate Metabolism.

Background/aims: Increasing evidence shows that reprogramming of energy metabolism is a hallmark of cancer. Considering the emergence of microRNAs as crucial modulators of cancer, this study aimed to better understand the molecular mechanisms of miR-124 in regulating glycolysis in human pancreatic cancer.

Methods: RT-PCR was used to investigate the expression of monocarboxylate transporters (MCTs) in pancreatic ductal adenocarcinoma (PDAC) patient samples and the PANC-1 cell line.

Removal of heavy metals from aqueous solution by carbon nanotubes: adsorption equilibrium and kinetics.

Carbon nanotubes prepared by catalytic chemical vapor deposition of hydrocarbon at 650 degrees C show good adsorption capability of Pb2+, Cu2+ and Cd2+ ions from aqueous solution after oxidized with concentrated nitric acid at 140 degrees C for 1 h. The specific surface area and particle size distribution of the as-grown and oxidized CNTs were studied by BET method and laser particle analyzer. Three kinetic models, that is, first-, pseudo second- and second-order, were used to investigate the adsorption data and the pseudo second-order model can represent the experimental data better than two others.

[Heparin-induced extacorporeal low-density lipoprotein-lipoprotein alpha-fibrinogen precipitation in 36 cases].

Objective: To observe the efficacy of heparin-induced extracorporeal low-density lipoprotein-lipoprotein alpha- fibrinogen precipitation (HELP) in clearing blood lipids.

Methods: Thirty-six patients were subjected to extracorporeal plasma lipid separation procedures that utilized heparin to induce the formation of the complex consisted of heparin, low-density lipoprotein cholesterol (LDL-C), lipoprotein and fibrinogen which was precipitated and consequently separated from the plasma. Blood samples were obtained from the patients both before and after the procedures to assay serum total cholesterol (CH), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), LDL-C, apoliprotein A (ApoA) and apoliprotein B (ApoB).
