Background Non-typhoidal Salmonella (NTS), a common cause of diarrheal enterocolitis, may also severe invasive diseases. Limited information on NTS infections in children is available China. Methods We performed retrospective study admitted to the Ningbo Women and Children’s Hospital with culture-confirmed between January 2012 December 2019. Clinical microbiological were collected. compared demographic, clinical antibiotic resistance variables (iNTS) non-invasive (non-iNTS) infections,...

Lapachol is a natural naphthoquinone compound that possesses extensive biological activities. The aim of this study to investigate the inhibitory effects lapachol on rat C6 glioma both in vitro and vivo, as well potential mechanisms. antitumor effect was firstly evaluated model Wistar rats. cell proliferation, apoptosis DNA damage were detected by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS)/ phenazinemethosulfate (PMS) assay, hoechst 33358...

Extracts of the plant Hypericum perforatum L. have been traditionally used in folk medicine for treatment depressive disorders. Xanthone, a component L., has shown to be effective animal models depression.We investigated if 2 xanthone derivatives (1101 and 1105) were as venlafaxine, which is serotonin-norepinephrine reuptake inhibitor was positive control, depression.A series from designed synthesized. After preliminary experiments, considered our mouse depression model. To further determine...

We evaluate the value of progressive muscle relaxation (PMR) for patients with lumbar disc herniation after surgery based on a difference-in-differences model. A total 128 who underwent were randomly assigned to undergo either conventional intervention (conventional group,

One primary difficulty preventing the visual localization for service robots is robustness against changes, including environmental changes and perspective changes. In recent years, learning-based feature matching methods have been widely studied effectively verified in practical applications. Learning-based solves problem of illumination man-made However, there still room improvement dealing with large this letter, we leverage local planar motion property to simplify affine transform...

The study was designed to investigate the impact of radiofrequency catheter ablation on plasma level B-type natriuretic peptide (BNP). In 36 patients who underwent paroxysmal supraventricular tachycardia, BNP analyzed before and after procedures. at baseline, 30 minutes ablation, 3 24 hours 12.78 +/- 2.47, 18.45 4.02 (P = 0.446), 43.54 8.12 0.0001), 17.88 4.71 0.493) pg/mL, respectively. Plasma troponin I also increased (n 10, P < 0.05). Multivariate regression analysis showed a significant...

The primary aim of the study was to investigate whether there is a difference in plasma B-type natriuretic peptide (BNP) levels among left ventricular systolic dysfunction caused by different types heart disease.Plasma BNP measured patients with as result mitral valve regurgitation (n=26), hypertension (n=36), coronary disease (n=37) and dilated cardiomyopathy (n=32). end-diastolic diameter ejection fraction were assessed echocardiography. valvular group had more women younger (p < 0.05)....

The wide-scale adoption of transgenic crops has aroused public concern towards potential impacts to the ecological services soil fauna, such as nematodes. However, few studies examined whether cultivation rice would pose greater threats nematode community and associated functions than pesticide application. Moreover, what are determinants in paddy fields remains unclear. During a 3-year field study, rhizosphere samples transgenic-Bt rice, its counterpart non-Bt parental not-Bt with...

Lapachol is an active compound for the treatment of malignant brain glioma. However, its physicochemical properties limit clinical application. The purpose this study to develop a nano-drug delivery system (LPC-LP) loaded with lapachol (LPC), which remarkably prolongs half-life in body, and increases intake, therefore, achieving better anticancer effect In order optimize formulation liposomes, orthogonal design was adopted entrapment efficiency (EE) as index. characterization optimized...

OBJECTIVE To investigate the factors that may predict occurrence of depression in patients with primary hypertension. METHODS We conducted a cross-sectional survey on 891 hypertensive and 651 normal subjects (control group) from single community. Zung self-rating scale (SDS) was applied to evaluate symptoms depression, which diagnosed when SDS score >41. RESULTS There no significant difference gender distribution (female, 48.5 vs. 47.6%) age (65.3±9.2 64.0±7.9 years) between control groups...

To evaluate the impact of mild to moderate commissural calcification on immediate outcomes percutaneous balloon mitral valvuloplasty (PBMV).We analysed results 223 consecutive patients (mean age 37.6 +/- 8.7 years) who underwent PBMV for rheumatic stenosis. Commissural was identified with a two-dimensional echocardiography (echo) in 65 (29.1%) severity being graded from 0-3. The anatomy and function valve were assessed byWilkins echo score. In no increase area after 0.90 0.42 cm2, which...

The designed for 8×8×8 light-cube system. can dynamically statically, suitable media information decorative display. It provides a theoretical practical basis further development 3D

With the rapid development of radar industry technology, corresponding signal processing technology becomes more and complex. For with short-range detection function, its mostly presents characteristics wide bandwidth multiresolution. In traditional data process, a large number signals will interfere signal, which makes final difficult or even impossible. Based on this problem, paper proposes principal component linear prediction algorithm based clutter suppression basis algorithm. According...

This article divides the cooperation style between start-ups and venture investors into non-property property cooperation. On basis, it sets up a dynamic game model of complete information to figure out corresponding Nash equilibrium. And analysis results indicate that during cooperative process start-up investor, higher extra input investor needs provide, more likely both sides are choose cooperation; profits success project may bring, entrepreneurial firm is
