Risk of conversion from mild cognitive impairment to dementia in low- and middle-income countries: A systematic review and meta-analysis.

Introduction: With no treatment for dementia, there is a need to identify high risk cases to focus preventive strategies, particularly in low- and middle-income countries (LMICs) where the burden of dementia is greatest. We evaluated the risk of conversion from mild cognitive ompairment (MCI) to dementia in LMICs.

Methods: Medline, Embase, PsycINFO, and Scopus were searched from inception until June 30, 2020.

Rheumatoid arthritis (RA) is an autoimmune disease with nearly 1.6 billion patients worldwide and an incidence of 0.5-1%.

Use of ixekizumab in an HIV-positive patient with psoriatic arthritis.

Psoriasis is a chronic immune-mediated disease of the skin. The incidence of psoriasis among people living with HIV (PLHIV) is higher than that in the general population. The mechanism is complex, the manifestations are varied, and the treatment is difficult.

Tin Oxide (SnO) Nanoparticles: Facile Fabrication, Characterization, and Application in UV Photodetectors.

Tin oxide (SnO) nanomaterials are of great interest in many fields such as catalytic, electrochemical, and biomedical applications, due to their low cost, suitable stability characteristics, high photosensitivity, etc. In this contribution, SnO NPs were facilely fabricated by calcination of tin (II) oxalate in air, followed by a liquid-phase exfoliation (LPE) method. Size-selected SnO NPs were easily obtained using a liquid cascade centrifugation (LCC) technique.

Mesenchymal Stem Cell-Derived Extracellular Vesicle-Shuttled microRNA-302d-3p Represses Inflammation and Cardiac Remodeling Following Acute Myocardial Infarction.

Our research intended to investigate the roles of mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) in acute myocardial infarction (AMI) via delivery of microRNA (miR)-302d-3p. AMI mouse models were established. EVs isolated from MSCs with miR-302d-3p mimic were injected near the infarct area or co-cultured with hypoxic cardiomyocytes to evaluate their effects.

Rapid, sensitive and cost-effective determination of immune checkpoint inhibitor activity using a magnetic bead-based binding assay.

Immune checkpoint Inhibitors (ICIs) are effective immunno-therapeutic agents for cancer. Rapid and sensitive determination of the blocking activity of ICIs is important for ICIs development and immunological research. Among various immune checkpoint (IC) binding assays, cell-based binding assays are widely regarded, and the functional ELISA is a convenient alternative.

Prevalence and Risk of Mild Cognitive Impairment in Low and Middle-Income Countries: A Systematic Review.

Background: Mild cognitive impairment (MCI) is a cognitive state associated with increased risk of dementia. Little research on MCI exists from low-and middle-income countries (LMICs), despite high prevalence of dementia in these settings.

Objective: This systematic review aimed to review epidemiological reports to determine the prevalence of MCI and its associated risk factors in LMICs.

Specific PIWI-interacting small noncoding RNA expression patterns in pulmonary tuberculosis patients.

PIWI-interacting RNAs (piRNAs) play crucial roles in germline development and carcinogenesis. The expression patterns of piRNAs in pulmonary tuberculosis (PTB) are still unclear. Small RNA sequencing was applied to investigate peripheral blood piRNA expression patterns in PTB patients and healthy individuals.

Metabolic and proteomic mechanism of benzo[a]pyrene degradation by Brevibacillus brevis.

Benzo[a]pyrene (BaP) is a model compound of polycyclic aromatic hydrocarbons. The relationship between its toxicity and some target biomolecules has been investigated. To reveal the interactions of BaP biodegradation and metabolic network, BaP intermediates, proteome, carbon metabolism and ion transport were analyzed.

Factors affecting the separation performance of proteins in capillary electrophoresis.

Capillary electrophoresis (CE) is an effective tool for protein separation and analysis. Compared with capillary gel electrophoresis (CGE), non-gel sieving capillary electrophoresis (NGSCE) processes the superiority on operation, repeatability and automaticity. Herein, we investigated the effect of polymer molecular weight and concentration, electric field strength, and the effective length of the capillary on the separation performance of proteins, and find that (1) polymer with high molecular weight and concentration favors the separation of proteins, although concentrated polymer hinders its injection into the channel of the capillary due to its high viscosity.

Drug resistance mutation profiles of the drug-naïve and first-line regimen-treated HIV-1-infected population of Suzhou, China.

Little is known about the prevalence of drug-resistant mutations in HIV-1-positive individuals in Suzhou, China. To elucidate the transmitted drug resistance (TDR) and acquired drug resistance mutation (ADR) profiles, we collected blood specimens from 127 drug-naïve and 117 first-line drug-treated HIV-1-infected individuals sampled from 2014 to 2016 in Suzhou. We successfully amplified pol fragments from 100 drug-naïve and 20 drug-treated samples.

Effects of citrate acid concentrate (citrasate®) on heparin N requirements and hemodialysis adequacy: a multicenter, prospective noninferiority trial.

Background: Citrasate®, citric acid dialysate (CD), contains 2.4 mEq of citric acid (citrate), instead of acetic acid (acetate) as in standard bicarbonate dialysate. Previous studies suggest CD may improve dialysis adequacy and decrease heparin requirements, presumably due to nonsystemic anticoagulant effects in the dialyzer.

Validation of the sleep impact scale in patients with major depressive disorder and insomnia.

Objectives: Chronic insomnia and depression are often associated. Measuring the impact on quality of life associated with changes in sleep in co-treatment of insomnia and depression requires a valid and reliable patient reported outcome (PRO) instrument. This study aimed to assess the validity of the Sleep Impact Scale (SIS), a sleep-specific PRO instrument, in a population comorbid with Major Depressive Disorder (MDD) and insomnia to support its use in clinical or clinical trial applications.

Dietary intake of n-6 fatty acids modulates effect of apolipoprotein A5 gene on plasma fasting triglycerides, remnant lipoprotein concentrations, and lipoprotein particle size: the Framingham Heart Study.

Background: Apolipoprotein A5 gene (APOA5) variation is associated with plasma triglycerides (TGs). However, little is known about whether dietary fat modulates this association.

Methods And Results: We investigated the interaction between APOA5 gene variation and dietary fat in determining plasma fasting TGs, remnant-like particle (RLP) concentrations, and lipoprotein particle size in 1001 men and 1147 women who were Framingham Heart Study participants.

Genome-wide linkage analyses and candidate gene fine mapping for HDL3 cholesterol: the Framingham Study.

High density lipoprotein cholesterol (HDL-C) is inversely associated with coronary heart disease and has a genetic component; however, linkage to HDL-C is not conclusive. Subfractions of HDL, such as HDL(3)-C, may be better phenotypes for linkage studies. Using HDL(3)-C levels measured on 907 Framingham Heart Study subjects from 330 families around 1987, we conducted a genome-wide variance components linkage analysis with 401 microsatellite markers spaced approximately 10 centimorgan (cM) apart.

Influence of the APOA5 locus on plasma triglyceride, lipoprotein subclasses, and CVD risk in the Framingham Heart Study.

Several polymorphisms in the APOA5 gene have been associated with increased plasma triglyceride (TG) concentrations. However, associations between APOA5 and lipoprotein subclasses, remnant-like particles (RLPs), and cardiovascular disease (CVD) risk have been less explored. We investigated associations of five APOA5 single-nucleotide polymorphisms (SNPs; -1131T>C, -3A>G, 56C>G IVS3+ 476G>A, and 1259T>C) with lipoprotein subfractions and CVD risk in 1,129 men and 1,262 women participating in the Framingham Heart Study.

The APOA5 locus is a strong determinant of plasma triglyceride concentrations across ethnic groups in Singapore.

Singapore comprises three ethnic groups: Chinese (76.7%), Malays (14%), and Asian-Indians (7.9%).
