A new method for evaluating the injection effect of chemical flooding

Hall plot analysis, as a widespread injection evaluation method, however, often fails to achieve the desired result because of the inconspicuous change of the curve shape. Based on the cumulative injection volume, injection rate, and the injection pressure, this paper establishes a new method using the ratio of the pressure to the injection rate (RPI) and the rate of change of...

LncRNA CAIF inhibits autophagy and attenuates myocardial infarction by blocking p53-mediated myocardin transcription

Increasing evidence suggests that long noncoding RNAs (lncRNAs) play crucial roles in various biological processes. However, little is known about the effects of lncRNAs on autophagy. Here we report that a lncRNA, termed cardiac autophagy inhibitory factor (CAIF), suppresses cardiac autophagy and attenuates myocardial infarction by targeting p53-mediated myocardin transcription...

Aqueous Synthesis of ZnSe/ZnS-2-R-Benzothiazole Nanocrystals with White Emission

We prepared water-soluble white light-emitting ZnSe/ZnS-2-R-benzothiazole nanocrystals (NCs), R = 2-hydroxy-5-(2,5-dimethyl-thienyl)-phenyl. The penicillamine (Pen) capped ZnSe/ZnS NCs were firstly prepared with high photoluminescence quantum yields (PL QY) of 40%. Then they bond to 2-R-benzothiazole molecules, resulting in white light-emitting ZnSe/ZnS-2-R-benzothiazole NCs with...

Synthesis of Luminescent Ag Nanoclusters with Antibacterial Activity

This paper focuses on the synthesis of novel Ag nanoclusters (NCs) using DHLA as capping reagents in aqueous solution by a photoreduction method. Luminescence studies indicated that the DHLA-Ag NCs exhibited strong blue emission with maximum peak at 480 nm. The maximum emission of the NCs can be greatly improved with irradiating time by around 15-fold from 3 h to 67 h. By means...

Allitridi Inhibits Multiple Cardiac Potassium Channels Expressed in HEK 293 Cells

Allitridi (diallyl trisulfide) is an active compound (volatile oil) from garlic. The previous studies reported that allitridi had anti-arrhythmic effect. The potential ionic mechanisms are, however, not understood. The present study was designed to determine the effects of allitridi on cardiac potassium channels expressed in HEK 293 cells using a whole-cell patch voltage-clamp...

PRIMARY AND SECONDARY GLOMERULONEPHRITIDES 1

Introduction and Aims: Loss of podocytes in primary glomerulopathies is crucial for glomerulosclerosis progression which leads to end-stage renal failure in such patients. The mechanism of direct replacement of injured podocytes does not exist so the only way to compensate the integrity of glomerulus is change of cells shape to cover the glomerular tuft with a smaller number of...
