The multi-slice CT scanner refers to a special system equipped with multiple-row detector array simultaneously collect data at different slice locations. has the capability of rapidly scanning large longitudinal (z) volume high z-axis resolution. It also presents new challenges and characteristics. In this paper, we study scan reconstruction principles helical in general 4-slice particular. computed tomography consists following three key components: preferred pitches for efficient z...

Postpartum depression was associated with maternal suffering and diminished functioning, increased risk of marital conflict as well adverse child outcomes. Perceived social support during pregnancy postpartum among women. However, its causal relationship remains unclear. Therefore, we prospectively evaluate the association between perceived early depressive symptoms. We examined whether affected symptoms at 6 weeks in a cohort 3310 were assessed by ENRICHD Social Support Instrument (ESSI)...

Abstract Background Preoperative prediction of the Lauren classification in gastric cancer (GC) is very important to choice therapy, evaluation prognosis, and improvement quality life. However, there not yet radiomics analysis concerning straightly. In this study, a radiomic nomogram was developed preoperatively differentiate diffuse type from intestinal GC.

To develop and evaluate a diffusion-weighted imaging (DWI) deep learning framework based on the generative adversarial network (GAN) to generate synthetic high-b-value (b =1500 sec/mm2) DWI (SYNb1500) sets from acquired standard-b-value = 800 (ACQb800) 1000 (ACQb1000) sets.This retrospective multicenter study included 395 patients who underwent prostate multiparametric MRI. This cohort was split into internal training (96 patients) external testing (299 datasets. create SYNb1500 ACQb800...

Background Although some studies have reported that aquaporin-4 (AQP4) plays an important role in the brain edema after traumatic injury (TBI), little is known about AQP4 expression early stage of TBI, or correlation between structural damage to blood-brain barrier (BBB) and angioedema. The aim this project was investigate relationship BBB at stages TBI. Methods One hundred twenty healthy adult Wistar rats were randomly divided into two groups: sham operation group (SO) TBI group. five...

A multislice helical computed tomography (CT) half-scan (HS) reconstruction algorithm is proposed for cardiac applications. The imaging performances (in terms of the temporal resolution, z-axis image noise, and artifacts) HS are compared to existing algorithms using theoretical models clinical data. model resolution performance sensitivity profile) established CT, in general, i.e., any number detector rows used. It concluded that results improved than corresponding 180/spl deg/ LI (linear...

We investigated whether nonmedical opioid pain reliever use is associated with higher mortality in the general US population.We assessed history of among 9985 people interviewed at baseline Epidemiologic Catchment Area Program initiated 1981 to 1983 Baltimore, Maryland; St. Louis, Missouri; and Durham, North Carolina. linked data National Death Index through 2007.Nonmedical was 1.4%. Compared no drug use, increased for (hazard ratio [HR] = 1.60; 95% confidence interval [CI] 1.01, 2.53) or...

Abstract We present a description and analysis of mouse model for pulmonary interstitial fibrosis that is induced by specific immune response to small reactive chemical group called trinitrophenyl. describe the model, then we examine cellular mechanism induction fibrosis. The increase in hydroxyproline reached peak day 7 persisted through 28 all animals were sensitized challenged with hapten. Distinct patterns seen histologically correlated antigenic pretreatment dependent on T lymphocytes....

To evaluate the safety of bevacizumab combined with platinum-based thoracic perfusion for treating lung cancer-related malignant pleural effusion (MPE) through meta-analysis.The CNKI, PubMed, Cochrane Library, Embase, Chinese Science and Technology Journal Database (VIP), Wanfang Databases were searched randomized controlled trials (RCTs) treatment MPE. The references included in articles manually additional studies. A meta-analysis RCTs was conducted using RevMan 5.3 application.A total 8...

A number of processes and pathways have been reported in the development Group I pulmonary hypertension (Group PAH); however, novel biomarkers need to be identified for a better diagnosis management. We employed robust rank aggregation (RRA) algorithm shortlist key differentially expressed genes (DEGs) between PAH patients controls. An optimal diagnostic model was obtained by comparing seven machine learning algorithms verified an independent dataset. The functional roles DEGs were analyzed...

Abstract Background The depth-predicting score (DPS) was proposed based on conventional white-light imaging (C-WLI) endoscopic features of early gastric cancer (EGC) to determine the invasion depth neoplasm. However, effect DPS training endoscopists remains unclear. Therefore, we aimed investigate short-term improving diagnostic ability EGC and compare among non-expert at different levels. Methods In session, definitions scoring rules were instructed, classic C-WLI example graphics exhibited...

Background: Lipoprotein(a) [Lp(a)] is a well-established risk factor for ischaemic stroke (IS). It unclear whether Lp(a) associated with IS in patients atrial fibrillation (AF). The aim of this study to explore the association between concentration and AF patients, hope find potential patients. Methods: This retrospective cohort study. screened January 2017 July 2021 were matched at 1:1 by propensity score matching (PSM) method Second Affiliated Hospital Nanchang University. Associations...

The long-term use of aspirin for preventing cardiovascular disease has been recommended decades. However, there is currently uncertainty regarding the effects on risk all-cause, cardiovascular, and cancer mortality in patients. aim this work was to analyze connection between prophylactic low-dose all-cause death, carcinoma death patients United States. A cohort study conducted using National Health Nutrition Examination Survey (NHANES) data (2011–2012, 2013–2014, 2015–2016, 2017–2018)...

Depression is a neurophysiological disorder with recurrent dysregulations of self-mental states. Multiscale Approximate entropy (ApEn) and Sample (SampEn) are employed to characterize nonlinear complexity Magnetoencephalography (MEG) depressive patients in our contribution. SampEn shares similarities ApEn while has better distinctions between the MEGs depression normal people. Test results prove that MEG lower than subjects, indicating weaker response emotional stimuli, optimum...
