Abstract Background Odor identification (OI) dysfunction is an early marker of Alzheimer’s disease (AD), but it remains unclear how olfactory-related regions change from stages subjective cognitive decline (SCD) and mild impairment (MCI) to AD dementia. Methods Two hundred sixty-nine individuals were recruited in the present study. The defined as interest, grey matter volume (GMV), low-frequency fluctuation, regional homogeneity (ReHo), functional connectivity (FC) compared for exploring...

Cognitive decline is a prevalent health problem in older adults, and effective treatments remain to be produced. Serum vitamin D, commonly used biochemical marker, widely recognized as an indicator of various diseases. Existing research has not fully elucidated the relationship between D cognitive function. The aim this study investigate real function identify indicators that have strong predictive effect on decline. At first, we dataset genome-wide association studies studying performance...

The recurrence of polyps after endoscopic treatment is a difficult problem and there may be an association between blood lipid levels colorectal polyps, but this controversial the aim study to explore risk factors for polyp recurrence.A total 357 patients who underwent intestinal polypectomy from January 1, 2019 June 2020 in Sichuan Provincial People's Hospital were included retrospective analyze potential indices risk. Polyp was defined as detection 1 or more at any time polypectomy,...

Hypoxia spontaneously forms in the interior of glioma tissues and regulates expression various genes. However, status hypoxia-driven genes is not completely known. In current study, RNA-seq data 695 The Cancer Genome Atlas (TCGA) were set as a discovery cohort used to identify construct novel gene signature. prognostic values that signature verified from TCGA Chinese Glioma (CGGA). diagnostic analyzed using immunohistochemistry receiver operator characteristic curves. Finally, effects on...

Major depressive disorder (MDD) is a common psychiatric disease and leading cause of disability worldwide. Handgrip strength (HGS) as an objective physical fitness test practical index for identifying many diseases. Previous studies drew different conclusions about the relationship between HGS MDD.We aim to explore whether has effect on risk MDD.HGS-related single-nucleotide polymorphisms identified by genome-wide association study were used instrumental variables in this Mendelian...

Insulin resistance, a pathological response to insulin hormone in insulin-dependent cells, is characterized by the presence of high glucose and concentrations. The homeostasis model resistance (HOMA-IR) one most used indexes estimate assessing fasting levels. An association was observed between vitamin D levels which varied different ethnic groups, there some evidence that supplementation could contribute improvement resistance. This study assessed 25-hydroxyvitamin (25[OH]D) concentration...

Rapid laboratory detection is essential to diagnose norovirus infection. LAMP has many advantages compared with RT-PCR for detecting norovirus, including high sensitivity, specificity, rapidity, low cost, and intuitive results, which can be easily read the naked eye help of color-based reporters. In this study, we intend analyze accuracy methods diagnosis infection.Two researchers independently retrieved relevant literature up January 2021 (PubMed, Web Science, Cochrane Library, Embase,...

Objective Observational studies have reported that major depressive disorder (MDD) is associated with sedentary behavior (SB) and multiple chronic pain (MCP), but their associations remain unclear. Mendelian randomization analysis was used to assess the association. Methods Single nucleotide polymorphisms (SNPs) MCP, SB [time spent watching television (Tel), using a computer (Com), or driving (Dri)], MDD were collected from genome-wide association screened as instrumental variants threshold...

Abstract In order to increase the service life of mixer blades, reliability blades is optimized. this paper, blade calculated by combining stress-strength interference model and discrete element method. Furthermore, orthogonal experimental design regression analysis are combined obtain a significantly higher equation with fewer experiments. According established relationship between parameters as goal, particle swarm optimization used optimize mixer. Finally, twin-shaft that mixes foamed...

Abstract As an important part of mixing material, the study on reliability life blade mixer is very necessary. According to Arcard wear formula, mathematical model expression amount and load blades twin-shaft in a single cycle established. The discrete element method used obtain process. law distribution obtained by Lilliefers method. Furthermore, Lagrange interpolation analyze static simulation results blade, total when reaches critical thickness obtained. By establishing functional...
