Liver biopsies were performed to assess the severity of liver inflammation and fibrosis, which were graded using the Scheuer scoring system.

The Effects of Ultrasound on the Rehydration of Konjac Glucomannan/Soy Protein Isolate Gel and Simulation of Gas-Liquid Interface Evolution During the Rehydration Process.

Soy protein isolate (SPI) possesses potential gelling properties, making it suitable for gel-based applications. However, the gel network stability and mechanical properties of SPI are relatively poor and can be improved through modifications or by combining it with other polymers, such as Konjac Glucomannan (KGM). Combining SPI with KGM can overcome the poor gel network stability and mechanical properties of SPI, but it reduces the water-absorbing capacity of the gel network after drying, which affects the quality characteristics of plant-based protein rehydrated foods and limits the economic feasibility of soy protein foods.

1,4-Dioxo-1,2,3,4-tetrahydrophthalazine-6-carboxylic acid as a novel MALDI matrix for enhanced analysis of metabolites induced by imidacloprid exposure.

Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) has become a robust tool for analyzing a variety of biomacromolecules. However, the strong background interference produced by conventional organic matrices hinders the detection of small molecule analytes, which restricts the widespread application of MALDI-MS in metabolomics studies. Consequently, developing new organic matrices is urgently needed to overcome these issues.

Base-Controlled Synthesis of Heteroatom-Embedded 9-Membered Cycloalkynes and 6-Membered Sultams through Copper-Catalyzed Cyclization.

A facile copper-catalyzed, base-controlled cyclization reaction has been developed for the synthesis of 9-membered cycloalkyne and 6-membered heterocycle sultams under mild conditions. This protocol utilizes a copper-catalyzed intramolecular A (alkyne-aldehyde-amine) coupling reaction to efficiently synthesize 9-membered cycloalkyne sultams in yields up to 90%. Alternatively, by substituting NaHCO with DBU, the protocol achieves selective deprotection of the -propargyl group, thereby facilitating the formation of 6-membered heterocyclic sultams, also in high yields.

Effect of regional crosstalk between sympathetic nerves and sensory nerves on temporomandibular joint osteoarthritic pain.

Temporomandibular joint osteoarthritis (TMJ-OA) is a common disease often accompanied by pain, seriously affecting physical and mental health of patients. Abnormal innervation at the osteochondral junction has been considered as a predominant origin of arthralgia, while the specific mechanism mediating pain remains unclear. To investigate the underlying mechanism of TMJ-OA pain, an abnormal joint loading model was used to induce TMJ-OA pain.

Hepatic and intestinal insights into the molecular mechanisms of dietary Antarctic krill-induced body color differentiation in Plectropomus leopardus.

Antarctic krill (Euphausia superba), which is rich in astaxanthin, has been widely utilized as a dietary supplement in fish aquaculture. Our study was to feed juvenile leopard coral grouper (Plectropomus leopardus) a diet containing 50 % Antarctic krill, revealing significant body color differentiation between a reddened group (BKR) and a non-reddened group (BKB), followed by comparative analysis with the control group (BCon) without krill supplementation. Histological analysis and carotenoid content in the liver and intestine were differentially regulated in color-differentiated individuals.

Using different configurations of -planted constructed wetland-microbial fuel cells to remove Cr (Ⅵ) and p-chlorophenol and generate electricity.

PD-like pathogenesis induced by intestinal exposure to microplastics: An in vivo study of animal models to a public health survey.

With the increasing incidence of non-hereditary Parkinson's disease (PD), research into the involvement of specific environmental factors, in addition to aging, has become more prominent. The effects of microplastic exposure on public health have gained increased attention as it is known to cause a range of neurotoxic changes, some of which are similar to the pathological features of PD. We carried out low-dose microplastic exposure experiments on mice and Caenorhabditis elegans models and implemented a survey regarding the utilization of plastic products in the population.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Integration of the rat liver micronucleus assay into a 28-day treatment protocol: testing the genotoxicity of four small-molecule nitrosamines with different carcinogenic potencies and tumor target specificities.

Several potent carcinogenic nitrosamines, including N-nitrosodiethylamine (NDEA) and N-nitrosodimethylamine (NDMA), induce micronuclei in the micronucleated hepatocyte (MNHEP) assay but not in the micronucleated reticulocyte (MNRET) assay. However, the MNHEP assay is not as frequently used as the MNRET assay for evaluating in vivo genotoxicity. The present study evaluated MN formation in the liver of Big Blue transgenic rats exposed to four small-molecule nitrosamines, NDMA, N-nitrosodiisopropylamine (NDIPA), N-nitrosoethylisoporpylamine (NEIPA), and N-nitrosomethylphenylamine (NMPA), using a repeat-dose protocol typically used for in vivo mutagenicity studies.
