Interaction between pea protein isolate and quercetin: Effects on protein conformation and quercetin activity.

Comprehensive comprehension of the interaction between proteins and polyphenols is crucial for advancing their utilization in food processing. This study investigated no-covalent interaction between pea protein isolate (PPI) and quercetin (Que) through spectroscopic analysis and molecular simulation. Fourier transform infrared spectroscopy and circular dichroism spectrum showed that the interaction between PPI and Que changed the secondary structure of the protein due to a decrease in α-helix content and an increase in the random coil.

Site-directed immobilization of enzymes on nanoparticles using self-assembly systems.

Enzyme immobilization is an effective method for improving the stability and reusability. However, linking at random sites on the enzyme results in low catalytic efficiency due to blockage of the active site or conformational changes. Therefore, controlling the orientation of enzymes on the carrier has been developed.

A novel de-escalation antiplatelet therapy for patients with acute coronary syndrome undergoing percutaneous coronary intervention.

To investigate the effect of different DAPTs in patients with ACS undergoing PCI, and to identify the most efficient DAPT to reduce the risk of ischemia and bleeding after PCI. Between March 2017 and December 2021, 1598 patients with ACS who underwent PCI were included in the study. The DAPT protocol included the clopidogrel group (aspirin 100 mg + clopidogrel 75 mg), ticagrelor group (aspirin 100 mg + ticagrelor 90 mg), de-escalation Group 1 (reduced dose of ticagrelor [from 90 mg to 60 mg]) after 3 months of oral DAPT [aspirin 100 mg + ticagrelor 90 mg]), and de-escalation Group 2 (switched from ticagrelor to clopidogrel after 3 months of oral DAPT [aspirin 100 mg + ticagrelor 90 mg]).

Clinical Effects and Safety of Auricular Acupressure as an Adjunct Therapy on Postoperative Pain among Patients with Hip Fracture: A Meta-Analysis.

Objectives: To evaluate the short-term outcome of treatment by auricular acupressure (AA) on postoperative pain among hip fracture (HF) patients.

Methods: A systematic search for randomized controlled trials on this topic was conducted through May 2022 by searching multiple English and Chinese databases. The methodological quality of the included trails was assessed by the Cochrane Handbook tool, and relevant data were extracted and statistically analyzed by RevMan 5.

The ameliorative effect of CangFu Daotan Decoction on polycystic ovary syndrome of rodent model is associated with m6A methylation and Wnt/β-catenin pathway.

This study investigates the effects of CangFu Daotan Decoction (CDD) on m6A methylation and Wnt/β-catenin pathway in rats with polycystic ovary syndrome (PCOS). The PCOS rat model was established by letrozole gavage. The rats were fed high-fat chow, and their body weight and blood glucose were recorded.

Wenhua Juanbi Recipe Attenuates Rheumatoid Arthritis via Inhibiting miRNA-146a-Mediated Autophagy.

Background: Wenhua Juanbi Recipe (WJR) is widely used for the treatment of rheumatoid arthritis (RA) in China. However, its mechanism of action remains unclear. This study was designed to investigate the potential therapeutic effects of WJR on the proliferation and apoptosis of synovial fibroblasts in RA and its efficacy in inhibiting miRNA-146a-mediated cellular autophagy.

Soluble FGL2, a novel effector molecule of activated hepatic stellate cells, regulates T-cell function in cirrhotic patients with hepatocellular carcinoma.

Purpose: To investigate the effects of soluble FGL2 (sFGL2) secreted by hepatic stellate cells (HSCs) on immune suppression in cirrhotic patients with hepatocellular carcinoma (HCC).

Methods: Serum sFGL2 levels were examined by ELISA in 40 patients with HCC, liver cirrhosis (LC) or chronic HBV (CHB) infection. A double staining of the immunofluorescence analysis of α-SMA and FGL2 was performed in two cirrhotic liver specimens.

A recursive least squares-based demodulator for electrical tomography.

In this paper, a recursive least squares (RLS)-based demodulator is proposed for Electrical Tomography (ET) that employs sinusoidal excitation. The new demodulator can output preliminary demodulation results on amplitude and phase of a sinusoidal signal by processing the first two sampling data, and the demodulation precision and signal-to-noise ratio can be further improved by involving more sampling data in a recursive way. Thus trade-off between the speed and precision in demodulation of electrical parameters can be flexibly made according to specific requirement of an ET system.

[Bone histocompatibility of surface modified nitinol memory alloy by coating titanium-niobium alloy].

Objective: Surface modification of nitinol (NiTi) shape memory alloy is an available method to prevent nickel ion release and coating with titanium-niobium (TiNb) alloy will not affect the superelasticity and shape memory of NiTi. To evaluate the bone histocompatibility of NiTi shape memory alloy implants coated by TiNb in vivo.

Methods: NiTi memory alloy columns which were 4 mm in diameter and 12 mm in length were coated with Ti (Ti-coating group) and TiNb alloy (TiNb-coating group) respectively by magnetron sputtering technique.
