Parental Psychological Control and College Students' Negative Risk-Taking Behaviors: The Chain-Mediating of Autonomy and Self-Control.

Purpose: To deeply explore the relationship between parental psychological control and negative risk-taking behaviors among Chinese college students and the mediating role of autonomy and self-control, providing a reference basis for preventing and intervening in college students' negative risk-taking behaviors.

Patients And Methods: Questionnaires was administered to 1173 college students (M=20.7 ± 1.

Constructing ROS-Responsive Supramolecular Gel with Innate Antibacterial Properties.

Bacterial infections, especially antibiotic-resistant bacterial infections, pose a significant threat to human health. Supramolecular gel with innate antibacterial properties is an advanced material for the treatment of bacterial infections, which have attracted great attention. Herein, a reactive oxygen species (ROS)-responsive innate antibacterial supramolecular gel is developed by a bottom-up approach based on phenylalanine and hydrazide with innate antibacterial properties.

Mitochondria-Targeting Polymer Micelles in Stepwise Response Releasing Gemcitabine and Destroying the Mitochondria and Nucleus for Combined Antitumor Chemotherapy.

Mitochondrial DNA and nuclear DNA are essential genetic material which play an important role in maintaining normal metabolism, survival, and proliferation of cells. Constructing a mitochondria-targeting stimuli-responsive nano-drug delivery system releasing chemotherapeutic agents in a stepwise response manner and destroying mitochondrial DNA and nuclear DNA simultaneously is an effective way to improve the anti-tumor effect of chemotherapeutic agents. In this study, a new mitochondria-targeting pH/ROS dual-responsive block copolymer TPP-PEG2k--(BS-AA) (P1), untargeted pH/ROS dual-responsive copolymer mPEG2k--(BS-AA) (P2), pH single-responsive copolymer (mPEG2k--(AH-AA) (P3), ROS single-responsive copolymer mPEG2k--(SA-TG) (P4), and non-responsive copolymer mPEG--PCL (P5) were constructed.

Establishment of a quantitative RT-PCR detection of SARS-CoV-2 virus.

Background: The outbreak of novel coronavirus disease 2019 (COVID-19) has become a public health emergency of international concern. Quantitative testing of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) virus is demanded in evaluating the efficacy of antiviral drugs and vaccines and RT-PCR can be widely deployed in the clinical assay of viral loads. Here, we developed a quantitative RT-PCR method for SARS-CoV-2 virus detection in this study.

Comparison of the Effects of Green and Black Tea Extracts on Na /K -ATPase Activity in Intestine of Type 1 and Type 2 Diabetic Mice.

Scope: Na /K -ATPase is an important membrane-bound enzyme and high levels of Na /K -ATPase activity in intestine result in increased monosaccharide absorption and aggravated undesirable postprandial hyperglycemia in diabetic. The aim is to characterize the effects of green and black tea extracts on the intestinal Na /K -ATPase.

Methods And Results: The STZ-induced type 1 diabetic mice model and high-fat diet combined with low-dose STZ-induced type 2 diabetic mice model are used in this study and the data indicate that both green and black tea extracts show significant hypoglycemic effect.

Evidence for implicit self-positivity bias: an event-related brain potential study.

We investigated the processing of self-related information under the prime paradigm using event-related potentials (ERPs) to provide evidence for implicit self-positivity bias in Chinese individuals. Reaction times and ERPs were recorded when participants made positive/negative emotional judgments to personality-trait adjectives about themselves or others. Faster responses occurred to self-related positive adjectives and other-related negative adjectives, indicating implicit self-positivity bias at the behavioral level.

Electrophysiological correlation of the degree of self-reference effect.

The present study investigated neural correlations underlying the psychological processing of stimuli with various degrees of self-relevance. Event-related potentials were recorded for names that differ in their extent of relevance to the study participant. Participants performed a three-stimulus oddball task.
