Discrimination and evaluation of commercial salmons by low-molecule-weight compounds: Oligopeptides and phosphatides.

In this study, the overall sensory characteristics and low-molecule-weight compounds were analyzed to achieve the discrimination of different commercial salmons and investigate the salmon's sensory and nutritional quality. The results showed that above the overall sensory properties, O. mykiss, S.

Analysis of Lipid Molecule Profiling and Conversion Pathway in Mandarin Fish () during Fermentation via Untargeted Lipidomics.

Lipids are the key aroma contributors and nutrients in fermented fish products. A total of 376 lipid molecules were identified in mandarin fish during fermentation by untargeted lipidomics, including glycerolipids, glycerophospholipids, lysoglycerophospholipid, sphingolipids, fatty acids (FAs), and sterol lipids. Both lipid composition and content changed dynamically during fermentation.

Design of diversified chimeric antigen receptors through rational module recombination.

Chimeric antigen receptor (CAR)-T cells have shown great promise in cancer therapy. However, the anti-tumor efficiency is limited due to the CAR-induced T cell apoptosis or exhaustion. The intracellular domain of CAR comprised of various signaling modules orchestrates CAR-T cell behaviors.

Pouring hot water through drip bags releases thousands of microplastics into coffee.

Microplastics (MPs) released from food packaging have attracted widespread attention. In this study, drip bags made from polyethylene (PE), polypropylene (PP), polyester (PET), and rayon selected from eight brands were employed to investigate MPs releasing. Fourier-transform infrared microspectroscopy (μ-FTIR), optical microscope and scanning electron microscope (SEM) were used to study the effects of brewing time and temperature on the release of MPs.

Rapid Fabrication of Patterned Gels via Microchannel-Conformal Frontal Polymerization.

From the perspective of both fundamental and applied science, it is extremely advisable to develop a facile and feasible strategy for fabricating gels with defined structures. Herein, the authors report the rapid synthesis of patterned gels by conducting frontal polymerization (FP) at millimeter-scale (2 mm), where a series of microchannels, including linear-, parallel-, divergent-, snakelike-, circular- and concentric circular channels, were used. They have investigated the effect of various factors (monomer mass ratio, channel size, initiator concentration, and solvent content) on FP at millimeter-scale, along with the propagating rule of the front during FP in these microchannels.

[Cloning, expression and identification of gametocyte specific protein Pfgdv1 of Plasmodium falciparum].

Objective: To clone a gametocyte specific protein Pfgdv1 of Plasmodium falciparum, express and identify recombinant Pfgdvl protein in vitro.

Methods: PCR was performed to amplify Pfgdv1 from P. falciparum DNA which was got from the patient who was infected with P.

[HCV DF protein inhibits expression of p16 and p21 in HepG₂ cells].

Aim: To investigate the effect of HCV DF (Double-shift F) protein on the expression p16 and p21 in HepG(2); cells.

Methods: DF gene was amplificated from the whole HCV 1b genome, and cloned into pCDNA3.0 vecter.
