Background: BRII-196 and BRII-198 are two recombinant human immunoglobulin (Ig) G1 monoclonal antibodies (mAbs) that non-competitively target distinct epitope regions within the receptor-binding domain (RBD) of the coronavirus spike glycoproteins. These antibodies are derived directly from human B cells of individuals who recovered from COVID-19.
Objective: To analyze the efficacy of BRII-196/BRII-198 in the treatment of coronavirus disease 2019 (COVID-19) vaccine breakthrough infections.
Background: (LR) is traditionally used in Mongolian folk medicine as a hypoglycemic agent, but its evidence-based pharmacological effects and me-chanisms of action have not been fully elucidated.
Aim: To emphasize the hypoglycemic action mechanism of LR in a type 2 diabetic rat model and examine potential biomarkers to obtain mechanistic understanding regarding serum metabolite modifications.
Methods: A high-fat, high-sugar diet and streptozotocin injection-induced type 2 diabetic rat model was established.
Objective: To investigate the nutritional risk, malnutrition, severe malnutrition, and malnutrition prevalence of different stages in chronic kidney disease (CKD) patients with and without diabetes mellitus using the Global Leadership Initiative on Malnutrition (GLIM), and to analyze the causes of malnutrition and to improve the clinical outcomes of patients for early intervention.
Methods: A total of 683 patients with CKD who were hospitalized in our hospital from January 2020 to January 2021 were enrolled and divided into subgroups 1 to 5 according to whether they were complicated with diabetes and glomerular filtration rate. Using the second step of the malnutrition (GLIM) diagnostic tool and 2 previously commonly used malnutrition assessment methods (body mass index <18.

Triploid breeding based on unilateral sexual polyploidization is an effective approach for genetic improvement of , which can integrate heterosis and ploidy vigor in an elite variety. However, the phenotypic divergence of unselected allotriploids with the same cross-combination remains poorly understood, and the contributions of ploidy, gender, and genotype effects on phenotypic variation are still unclear. In this study, wood and fiber traits, including basic density (BD), lignin content (LC), fiber length (FL), fiber width (FW), and fiber length/width (FL/W), were measured based on a 10-year-old clonal trial, including full-sib diploid and triploid hybrids of ( × 'Zheyin3#') × × , and contributions of ploidy, gender, and genotype effects on the variation of these traits, were disaggregated to enhance our understanding of triploid breeding.

In our previous study, a progeny with segregated ploidy levels was produced by an interploidy cross between diploid female parent × clone TB03 and triploid male parent × 'Yinzhong'. However, the chromosome compositions of aneuploid genotypes in the progeny were still unclear.

This study aimed to compare the training efficacy of a simplified feedback trainer with the traditional cardiopulmonary resuscitation (CPR) simulator in CPR training. A total of 60 soldiers were randomly allocated into three groups equally, trained with a simplified external cardiac massage (ECM) trainer named Soul Sheath (SS) (SS group), a Resusci Anne manikin (RA group), or traditional simulation training with instructor feedback, respectively.

Aim: To evaluate the protective effect and identify the mechanisms of action of SL-4 on gastroduodenal ulcer induced by pyloric ligation (PL) in rats.
Methods: PL was performed to induce gastric and duodenal ulcers in rats, which were then treated with oral SL-4 (1.
As both host and pathogen require iron for survival, iron is an important regulator of host-pathogen interactions. However, the molecular mechanism by which how the availability of iron modulates host innate immunity against bacterial infections remains largely unknown. Using the metazoan Caenorhabditis elegans as a model, we demonstrate that infection with a pathogenic bacterium Salmonella enterica serovar Typhimurium induces autophagy by inactivating the target of rapamycin (TOR).

We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs.
Methods: We carried out a 48-week, randomized, controlled, open-label non-inferiority trial at 12 sites in China.
The macrophages mediated inflammation participates in every stage of atherosclerosis. Attenuation of macrophages inflammatory responses by active ingredients in atherosclerotic plaques is benefit to atherosclerotic stabilization and regression, but meanwhile, it is highly desired to develop accurate therapeutics for reducing off-target effects. Previous studies revealed that the apoptotic bodies are effectively recognized and engulfed by macrophages own to increased exposure of phosphatidylserine (PtdSer), which is regarded as a key "eat-me" signal.

Increased endoplasmic reticulum (ER) stress plays an important role in the development of insulin resistance. In this study, we investigated the roles of miRNAs in regulating ER stress in the liver of rats with obesity.

In this study we developed a novel floating bed made from ceramsite and studied its effect on water quality, phytoplankton, bacteria and fish growth. Water quality was effectively regulated and controlled in ceramsite floating bed (CFB) ponds with an average transparency of 23.

However, little is known about the molecular mechanisms underlying activation of the UPR during immune responses. Using small RNA deep sequencing and reverse genetic analysis, we show that the microRNA mir-233 is required for activation of the UPR in Caenorhabditis elegans exposed to Pseudomonas aeruginosa PA14.

Autophagy, a conserved pathway that delivers intracellular materials into lysosomes for degradation, is involved in development, aging, and a variety of diseases. Accumulating evidence demonstrates that autophagy plays a protective role against infectious diseases by diminishing intracellular pathogens, including bacteria, viruses, and parasites. However, the mechanism by which autophagy regulates innate immunity remains largely unknown.

Methods: Forty male Sprague-Dawley rats were divided randomly into four groups: normal control group, model group, baicalin-treated group, and colchicine-treated group. Except for the normal control group, all rats in the other groups were administered with carbon tetrachloride to induce hepatic fibrosis.
The aim of this study was to investigate the relationship between anti-fibrotic effect of Panax notoginseng saponins (PNS) and serum cytokines in rat hepatic fibrosis. Hepatic fibrosis induced by carbon tetrachloride (CCl(4)) was studied in animal models using SD rats. Liver index, serum alanine amino transferase (ALT), aspartate amino transferase (AST), transforming growth factor-beta1 (TGF-beta1), tumour necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured, respectively.
