N-terminal pro-brain natriuretic peptide (NT-proBNP) has been demonstrated to be a sensitive and specific biomarker for heart failure (HF). Surface-enhanced Raman spectroscopy (SERS) technology can used accurately detect NT-proBNP at an early stage its advantages of high sensitivity, less wastage time consumption. In this work, we have new SERS-based immunosensor ultrasensitive analysis by using metal-organic frameworks (MOFs)@Au tetrapods (AuTPs) immobilized toluidine blue as SERS tag....

This study aims to evaluate risk and discover the distribution law for landslides, so as enrich landslide prevention theory method. It first selected Fengjie County in Three Gorges Reservoir Area area. The work involved developing a map using hazard vulnerability maps utilizing dataset from 2001 2016. was built historical records, satellite images extensive field surveys. Firstly, under four primary conditioning factors (i.e., topographic factors, geological meteorological hydrological...

In this work, one stimuli-responsive DNA microcapsule was designed to combine duplex-specific nuclease (DSN) amplification strategy and surface-enhanced Raman spectroscopy (SERS) technology for sensitive detection of microRNA 155 (miRNA 155). First, toluidine blue (TB) as dye CaCO3 core templates co-precipitated form TB@CaCO3 composite. Then, networks were layer by constructed with oligonucleotide layers cross-linked linker ssDNA L lock inside. the presence ethylenediaminetetraacetic acid,...

Abstract Currently, many e‐tailers can sell manufacturers' products on their online platforms through reselling or agency selling formats. However, how to choose the optimal sales formats has puzzled competitive with different channel roles. This paper uses stylized theoretical models study this problem by considering combined effects of e‐tailers' roles, each e‐tailer's referral fees, and difference in market shares. Our results show that if two common manufacturer's platforms, no matter...

This work aims to discuss and compare the inherent essence of different machine learning algorithms for landslide susceptibility models (LSMs), which is great significance accurate prevention detection landslides. A geospatial database was established in GIS based on various factors topography, geological conditions, environmental conditions human activities, including 22 conditioning 866 historical As model algorithms, ANN an operation composed a large number interconnected nodes, RF refers...

Abstract The conflict between the demands of ecological protection and economic development is increasingly prominent. Land use change sensitive to whether or profits dominate, prediction future land changes has become an important scientific issue. This article constructs a coupled model that comprises grey (GM), fuzzy multiple objective linear programming (FMOLP) simulation (FLUS). We used this calculate macro‐scale quantitative forecast using top‐down GM‐FMOLP model, calculated...

Carbon sequestration in grasslands has been proposed as an important means to offset greenhouse gas emissions from ruminant systems. To understand the potential and limitations of this strategy, we need acknowledge that soil carbon is a time-limited benefit, there are intrinsic differences between short- long-lived gases. Here, our analysis shows one tonne sequestrated can radiative forcing continuous emission 0.99 kg methane or 0.1 nitrous oxide per year over 100 years. About 135 gigatonnes...

This study provides a deep insight into Chinese consumer trust in the dairy value chain, as lack of due to 2008 melamine scandal has been widely recognized barrier development domestic industry China. Based on face-to-face interviews with 954 consumers Beijing, Shanghai, and Shijiazhuang, this measured farmers, manufacturers, retailers, government, third parties. Consumer was studied by measuring effect beliefs trustworthiness actors (i.e., competence, benevolence, integrity, credibility,...

High-yield dairy cows with high-concentrate diets are more prone to experiencing health problems associated rumen microbial imbalance. This study assessed the effects of Saccharomyces cerevisiae culture (SC), a food supplement, on ruminal pH, volatile fatty acid (VFA), inflammatory cytokines, and performance high-yield cows. Forty Holstein similar characteristics (e.g., milk yield, days milk, parity) were randomly divided into two groups: an experimental group fed basal ration supplemented...

The cecum serves as an additional fermentation site for ruminants, but it lacks buffering capacity and has a relatively simple epithelial structure compared to the rumen. role of high-grain (HG) diets in manipulating rumen microbiome been well elucidated, yet microbial response such subsequent microbe-host interactions remain largely unexplored. Here, we describe modification cecal host gene expression based on data from 20 sheep grouped feed HG diet 7, 14, 28 days. Our indicate that...

Background: In China, the increasing concentration of ozone (O3) has emerged as a significant air pollution issue, leading to adverse effects on public health, particularly respiratory system. Despite progress made in managing it is crucial address problem environmental O3 at present. Methods: The connection between exposure and mortality Shenyang, from 2014 2018 was analyzed by time-series generalized additive regression model (GAM) with quasi-Poisson regression. Additionally, potential...

The objectives of this study were to characterize changes in the relative mRNA expression candidate genes and proteins involved cell cycle regulation, proliferation apoptosis ruminal epithelium (RE) sheep during high-grain (HG) diet adaptation. Twenty assigned four groups with five animals each. These different periods HG (containing 40% forage 60% concentrate mix) feeding. received an for 7 (G7, n = 5), 14 (G14, 5) 28 d (G28, respectively. In contrast, control group (CON, was fed...

Rapid urbanization has already caused many impacts, such as environmental degradation and imbalanced resource allocation. As the frontiers of urbanization, urban fringe areas (UFAs) present both rural characteristics undergo complex socio-economic structural changes. Accurately identifying spatial extent UFAs is highly significant because it contributes to understanding pattern expansion guides future planning. However, existing methods are strongly affected by subjective factors. To solve...

A 60-day feeding trial was performed to assess the effects of dietary phosphorus levels on growth performance, body composition, utilization, plasma physiological parameters and intestinal Ca P transport-related gene expression juvenile Chinese soft-shelled turtle (P. sinensis). Four diets containing available at graded 0.88%, 1.00%, 1.18% 1.63% (termed as D0.88, D1.00, D1.18 D1.63, respectively) were formulated each diet fed turtles (5.39 ± 0.02 g) in sextuplicate. The randomly distributed...

Heavy metal contamination is one of the main factors causing ecological and environmental degradation. Soil by heavy metals decreases soil quality, reduces agricultural productivity even threatens human health. Therefore, optimizing remediation strategies for soils polluted with great significance high-yield, good-quality, sustainable agriculture. Numerous domestic foreign scholars have carried out a large number studies on phytoremediation contaminated soils. However, efficiency may be...
