[Evaluation and spatial-temporal variations of ecological comprehensive index along the Yellow River of Shanxi Province, China].

Ecological comprehensive index can quantitatively and visually analyze the temporal and spatial variations of ecological environment quality in a region. Based on the five indices of fractional vegetation coverage, leaf area index, total primary productivity, land surface temperature and wetness obtained by MODIS satellite data in 2001, 2005, 2010, 2015 and 2020, and coupled the comprehensive quality of the eco-environment (), we analyzed the temporal and spatial variations of ecological quality along the Yellow River of Shanxi Province from 2001 to 2020 by using the principal component analysis and spatial autocorrelation method. The results showed that the mean value of in the study area increased from 0.

Water exchange versus air insufflation for colonoscopy: A meta-analysis.

Background/aims: To compare water exchange (WE) method with conventional air insufflation (AI) method for colonoscopy, evaluating the technical quality, screening efficacy, and patients' acceptance.

Materials And Methods: Electronic databases were systematically searched for randomized controlled trials comparing WE colonoscopy with AI colonoscopy. The pooled data of procedure-associated and patient-related outcomes were assessed, using the weighted mean difference (WMD) with 95% confidence interval (CI) for continuous variables and relative risk (RR) with 95% CI for dichotomous variables, respectively.

The combined effect of non-alcoholic fatty liver disease and metabolic syndrome on colorectal carcinoma mortality: a retrospective in Chinese females.

Background: This research aimed to investigate whether metabolic syndrome (MetS) and non-alcoholic fatty liver disease (NAFLD) had both individual and synergistic effects on the prognosis for female colorectal carcinoma (CRC) patients.

Methods: The relationship between CRC prognosis and NAFLD as well as MetS was evaluated in 764 female participants. Based on the NAFLD level, patients were divided into significant NAFLD (SNAFLD), "moderate" and "severe" level, and non-SNAFLD, "non" and "mild" level.

Fibrinogen-like protein 2 prothrombinase may contribute to the progression of inflammatory bowel disease by mediating immune coagulation.

Inflammation and coagulation are interdependent processes that enable each process to activate and propagate the other in inflammatory bowel disease (IBD). Thus, we investigated the role of a novel immune coagulant, fibrinogen-like protein 2 prothrombinase (FGL2), in patients and mice with IBD. 83 IBD patients and 40 normal controls were enrolled, and trinitro-benzene-sulfonic acid (TNBS)-induced colitis mice were used.

Behavior regulation of adsorbed proteins via hydroxyapatite surface texture control.

The influence of nanometer-scale interfaces on proteins has received much attention in recent years. The dynamic behaviors of bone morphogenetic protein-7 (BMP-7) on a series of hydroxyapatite (HAP) surface textures were investigated to explore the influence of different surface textures using molecular dynamics (MD), steered molecular dynamics simulations (SMD), and quantum mechanics calculations. It is observed that the interaction energy curve from SMD simulations can exhibit the dynamic behavior of BMP-7 in detail.

[Synthesis and antitumor activity of anthracene-9-carbaldehyde amino-s-triazole Schiff-bases with side-chain of S-acetic acid].

To find out a novel lead compound from heterocyclic amine Schiff bases for developing new antitumor agents, each of (4-amino-5-substituted-s-triazol-3-ylthio) -acetic acids 2a-j was condensed with anthracene-9-carbaldehyde to obtain Schiff-bases of [4-(anthracen-9-yl methylene) amino] -5-substituted-s-triazol-3-ylsulfanyl] -acetic acids 3a-j. The structures of new compounds synthesized were characterized by elemental analysis and spectral data, and in vitro antitumor activity was also evaluated against CHO, HL60 and L1210 cell lines by MTT assay.
