Multiple sclerosis (MS) is an autoimmune disorder caused by chronic inflammatory reactions in the central nervous system. Currently, little is known about the changes of plasma proteomic profiles in Chinese patients with MS (CpwMS) and its relationship with the altered profiles of multi-omics such as metabolomics and gut microbiome, as well as potential molecular networks that underlie the etiology of MS. To uncover the characteristics of proteomics landscape and potential multi-omics interaction networks in CpwMS, Plasma samples were collected from 22 CpwMS and 22 healthy controls (HCs) and analyzed using a Tandem Mass Tag (TMT)-based quantitative proteomics approach.

The Ni-catalyzed enantioselective addition reaction of aryl halides to aldehydes was studied with cyanobis(oxazoline) as chiral ligands and Mn as reductant. Aryl and heteroaryl bromides reacted with phenyl aldehyde at room temperature to produce dibenzyl alcohols in 16-99 % yields with 53-92 % ees. Moreover, the coupling of phenyl chloride with a variety of aryl, heteroaryl and alkyl aldehydes was demonstrated in the presence of cyanobis(oxazoline)/Ni(II) at 60 °C in generally high yields with moderate enantioselectivities.

Background: Chondrocyte ferroptosis plays a critical role in the pathogenesis of osteoarthritis (OA), regulated by the SLC7A11/GPX4 signaling pathway. Icariin (ICA), a flavonoid glycoside, exhibits strong anti-inflammatory and antioxidant activities. This study investigated whether ICA could modulate the SLC7A11/GPX4 signaling to inhibit chondrocyte ferroptosis and alleviate OA.

Spinal Cord Injury (SCI), with its morbidity characteristics of high disability rate and high mortality rate, is a disease that is highly destructive to both the physiology and psychology of the patient, and for which there is still a lack of effective treatment. Following spinal cord injury, a cascade of secondary injury reactions known as ischemia, peripheral inflammatory cell infiltration, oxidative stress, etc. create a microenvironment that is unfavorable to neural recovery and ultimately results in apoptosis and necrosis of neurons and glial cells.

This study investigated the effect of gamma irradiation on smoked bacon quality during storage and developed a multi-quality prediction model based on gamma irradiation. Gamma irradiation reduced moisture content and improved the microbial safety of smoked bacon. It also accelerated protein and lipid oxidation and altered free amino acids and fatty acids composition.

When exposed to various microenvironmental stimuli, macrophages are highly plastic and primarily polarized into the pro-inflammatory M1-type and the anti-inflammatory M2-type, both of which perform almost entirely opposing functions. Due to this characteristic, macrophages perform different functions at different stages of immunity and inflammation. Inflammatory immune skin diseases usually show an imbalance in the M1/M2 macrophage ratio, and altering the macrophage polarization phenotype can either make the symptoms worse or better.

Article Synopsis
  • - The study investigates the effectiveness of posterior pericardiotomy (PP) in preventing postoperative atrial fibrillation (POAF) and pericardial effusion after cardiac surgery through a systematic review and meta-analysis of randomized controlled trials.
  • - Results from 14 trials involving 2275 patients demonstrate that PP significantly reduces the occurrence of POAF and pericardial effusion compared to the control group, indicating a risk ratio of 0.48 and 0.34, respectively.
  • - The conclusion suggests that PP is a safe and effective surgical technique for minimizing these complications, though it is important to be mindful of potential coagulation dysfunction risks associated with the procedure.

DNA methylation plays a potential role in the pathogenesis of Alzheimer's disease (AD). However, little is known about the global changes of blood leukocyte DNA methylome profiles from Chinese patients with mild cognitive impairment (MCI) and with AD, or the specific DNA methylation-based signatures associated with MCI and AD. In this study, we sought to dissect the characteristics of blood DNA methylome profiles in MCI- and AD-affected Chinese patients with the aim of identifying novel DNA methylation biomarkers for AD.

Calcium-sensing receptor (CaSR) is a G protein-coupled receptor, widely distributed in various tissues, including vascular endothelial cells and smooth muscle cells, which plays an important role in the migration and homing of stem/progenitor cells and the proliferation of tissue cells. Restenosis after Percutaneous coronary intervention (PCI) seriously affects its prognosis and application. Our previous research has found that ginsenoside Rg1 (GS-Rg1) can inhibit the occurrence of restenosis after balloon injury of the common carotid artery in rats, but the mechanism is still unclear.

Article Synopsis
  • - Rheumatoid arthritis (RA) is a chronic condition that causes ongoing joint inflammation, and treatments like adalimumab, an anti-TNF-α drug, have improved patient outcomes but can lead to rare side effects like severe thrombocytopenia.
  • - In a reported case, a patient being treated with adalimumab experienced a significant drop in platelet count, which was not improved by the usual treatments, indicating a rare complication of the medication.
  • - The patient ultimately responded well to intravenous immune globulin (IVIG) after trying multiple treatments, suggesting that immunoglobulins may be an effective option for managing severe thrombocytopenia caused by anti-TNF-α therapies.

The vinyl-substituted oxyallyl carbonates were exploited as a new C,O-dipole for enantioselective Pd-catalyzed (3+2) cycloaddition. The corresponding oxyallyl-Pd species was weakly nucleophilic to react with activated carbonyl compounds, affording multisubstituted and enantioenriched oxazolidinones and 1,3-dioxolanes with a high degree of chemo- and stereoselectivity. The synthetic transformations of oxazolidinone product were carried out to build enantioenriched α-chiral aminoketone and epoxy derivatives.
