Objective: In this study, we assessed the prognostic significance of the mean velocity of the pulmonary artery (mvPA) using CMR in patients who have heart failure with mildly reduced ejection fraction (HFmrEF) and pulmonary hypertension, both as a combined condition and individually.
Methods: This retrospective study involved 284 consecutive patients diagnosed with HFmrEF who were hospitalized and underwent CMR imaging to assess RV-PA coupling parameters, including mvPA. We collected baseline data clinical profiles, lab test results, and cardiac imaging findings of patients with HFmrEF who had at least two echocardiograms conducted three months apart.
Fructose intolerance in mammals is caused by defects in fructose absorption and metabolism. Fructose-1,6-bisphosphatase 1 (FBP1) is a key enzyme in gluconeogenesis, and its deficiency results in hypoglycemia as well as intolerance to fructose. However, the mechanism about fructose intolerance caused by FBP1 deficiency has not been fully elucidated.

To date, the time-consuming and costly fermentation process by strict anaerobes makes propionate production not ideal. In this study, we designed a new route for propionate production, in which 1,2-propanediol was first dehydrated to propionaldehyde and then to propionate by taking advantage of the robust oxidization capacity of the KT2440 strain.

The regulation of the expression of genes involved in metabolic pathways, termed as metabolic regulation, is vital to construct efficient microbial cell factories. With the continuous breakthroughs in synthetic biology, the mining and artificial design of high-quality regulatory elements have substantially improved our ability to modify and regulate cellular metabolic networks and its activities. The research on metabolic regulation has also evolved from the static regulation of single genes to the intelligent and precise dynamic regulation at the systems level.

We provide an overview about the features of fructose metabolism, as well as potential mechanisms by which excessive fructose intake is associated with the pathogenesis of metabolic diseases both in humans and rodents. To accomplish this aim, we focus on illuminating the cellular and molecular mechanisms of fructose metabolism as well as its signaling effects on metabolic and cardiovascular homeostasis in health and disease, highlighting the role of carbohydrate-responsive element-binding protein in regulating fructose metabolism.

The aim of this study was to identify potential metabolic profiles of moxibustion on relieving ankylosing spondylitis (AS) mice through UHPLC-Q-TOF/MS metabolomic study.
Methods: Thirty-two female Balb/c mice were randomized into healthy control (HC), AS model, moxibustion at acupuncture points (MA) in AS model, and moxibustion at non-acupuncture points (MNA) AS model groups.
Background: The aim of this review was to comprehensively summarize and analyze the current guidelines on home-based traditional Chinese medicine (TCM) nursing interventions for discharged patients with COVID-19.
Methods: Eight data sources were searched until June 28, 2020. The frequency of home-based TCM nursing interventions and the use of specific acupuncture points recommended in Chinese guidelines for discharged COVID-19 patients were computed and analyzed.
Aims: Previous studies suggest that small intestinal bacterial overgrowth (SIBO) is associated with type 2 diabetes. However, few studies have evaluated the association between SIBO and beta-cell function in type 2 diabetes. The aim of this study was to evaluate whether beta-cell function was associated with SIBO.

With whole genome and transcriptome sequencing, we depicted the feature of two multi-drug resistant Mtb strains in resistance and virulence. Compared with H37Rv, the differential expressed genes (DEGs) of the MDR strains showed featured enrichment in arginine biosynthesis, fatty acid biosynthesis, and metabolism pathway.

Here, we demonstrate that the downregulation of GPR183 in macrophage induced during Mtb infection restrains the bacterial early infection and intracellular replication. Overexpression of GPR183 or stimulation with its natural ligand favors Mtb replication in macrophage, while treatment with its antagonist represses both Mtb early infection and intracellular replication.

Carbohydrate response element-binding protein (ChREBP) is a transcription factor essential for fructose tolerance in mice. However, the functional significance of liver ChREBP in fructose metabolism remains unclear.

The application of sewage and manure in protected vegetable cultivation can induce the occurrence of heavy metals contamination. The present research studied the transformation of heavy metals (Cd, Cu, Pb and Zn) by incubating contaminated protected soil with maize straw and then leaching. The results showed that soil pH was significantly decreased, being more evident in maize straw treatment; soil Eh dropped quickly below -280 mV.

Objective: To understand the infection status of Fasciola and related risk factors in population of Binchuan County, Yunnan Province.
Methods: In February and March, 2014, 6 natural villages from 2 administrative villages in Zhoucheng Town were selected as investigated sites, and the permanent residents aged ≥ 5 years were examined by ELISA for the serum antibody detection, and then the positive ones were examined by Kato-Katz technique and the hatching method for Fasciola egg detection. Meanwhile, the fascioliasis cases that checked out by the above methods were further surveyed, and the residents who with the same gender, similar age and negative results in the blood examination were selected as the controls, then the risk factors were explored through a case control study.
Membranous nephropathy (MN) may be a primary disease or secondary to autoimmune conditions such as systemic lupus erythematosus, infection (for example, with hepatitis B or C virus), cancer or drugs. In primary MN, crescents are rarely observed. Therefore, the presence of crescents suggests another underlying disease, for example lupus nephritis, anti-glomerular basement membrane disease or anti-neutrophil cytoplasmic antibody-associated glomerulonephritis (ANCA-GN).

Thyroid hormone is reported to induce angiogenesis, which is mediated by the membrane receptor integrin αvβ3, but the precise signaling pathway is still not very clear. Recently, studies have shown that protein kinase D (PKD) regulates the recycling of integrin αvβ3, which is required for cell migration. Moreover, phosphorylated PKD stimulates histone deacetylase 5 (HDAC5) phosphorylation and nuclear export in endothelial cells.

This study was aimed to evaluate the proliferation-associated antigen Ki-67 expression in diffuse large B cell lymphoma (DLBCL) and its clinical significance. The Ki-67 expression and its correlation with prognosis in 50 patients with DLBCL treated with rituximab plus CHOP (R-CHOP) between January 2008 and December 2010 were analyzed retrospectively. The results indicated that there was no significant relationship between Ki-67 expression and clinical features, including age, sex, staging, B symptoms, LDH level, IPI, extranodal site involvement, presence of bulky tumors (>10 cm in diameter), bone marrow involvement, GCG nor GCB type, or response to first line treatment.
