Autocatalytic Reaction Networks: A Pathway to Spatial Temporal Mastery in Dynamic Materials.

Autocatalytic reaction present a significant opportunity for the precise spatial and temporal control of dynamic materials, mimicking the characteristics of living matter within autonomous chemical systems. Herein, we have crafted an autocatalytic chemical reaction network (CRN) designed to be incorporated into a dynamic system, allowing for efficient control of both sol(I)-gel and gel-sol(II) transitions through autocatalytic fronts. The CRN incorporates two autocatalytic reactions.

Maternal Genetic Diversity Analysis of Guanling Cattle by Mitochondrial Genome Sequencing.

Owing to the unique geography and the isolated environment, Guanling cattle, which is one of five local cattle breeds in Guizhou, China, has developed unique characteristics. The number of pure Guanling cattle decreased markedly because of the hybridization with foreign breeds. In the present study, the maternal genetic diversity of 58 Guanling bulls was assessed by whole mitochondrial genome sequencing.

Non-Equilibrium Dissipative Assembly with Switchable Biological Functions.

Natural dissipative assembly (DSA) often exhibit energy-driven shifts in natural functions. However, creating man-made DSA that can mimic such biological activities transformation remains relatively rare. Herein, we introduce a cytomembrane-like dissipative assembly system based on chiral supramolecules.

Non-Equilibrium Assembly of Atomically-Precise Copper Nanoclusters.

Accurate structure control in dissipative assemblies (DSAs) is vital for precise biological functions. However, accuracy and functionality of artificial DSAs are far from this objective. Herein, a novel approach is introduced by harnessing complex chemical reaction networks rooted in coordination chemistry to create atomically-precise copper nanoclusters (CuNCs), specifically Cu(µ-Cl)(µ-Cl)LCl (L = 4-methyl-piperazine-1-carbodithioate).

The Effect of Lactobacillus sakei on Growth Performance and Intestinal Health in Dogs: Gut Microbiota and Metabolism Study.

The gut microbiota is the largest and most complex ecosystem consisting of trillions of microorganisms, which influenced by various external factors. As an important probiotic species, Lactobacillus helps to improve gut microbial diversity and composition, underlying potential efficacy in growth performance and disease prevention. However, limited studies have been investigated the relationship between Lactobacillus sakei and intestinal health in dogs.

Effects of climate change and grazing intensity on grassland productivity-A case study of Inner Mongolia, China.

In the last 30 years, grassland productivity has declined seriously due to climate variations and unreasonable human activities. Therefore, to analyze the impact of different factors on grassland productivity, we selected three grassland stations of the Typical Steppe from west to east and collected 38 years of data. The Pearson Correlation and Fixed Effect Model were used to analyze the impact of precipitation, temperature, and grazing intensity on grassland productivity.

Effect of Mulberry Leaf TMR on Growth Performance, Meat Quality and Expression of Meat Quality Master Genes (, ) in Crossbred Black Goats.

This study was conducted to examine the effect of a mulberry leaf total mixed ration (TMR) diet on growth performance, apparent digestibility, meat quality and the expression of related meat-quality genes (ADSL, H-FABP) in crossbred black goats. Forty-four Guizhou crossbred black goats (Nubian black goat ♂ × Guizhou black goat ♀), weighing 33.43 ± 0.

An empirical study of the key factors affecting herders' purchasing decision on weather index insurance-A case study from inner Mongolia autonomous region, China.

The weather index insurance for mutton sheep (WIMS) is the first weather index insurance product that addresses the increased feeding cost-related risk of grassland animal husbandry herders in China. In 2019, the WIMS was implemented as a pilot project in 11 county regions of Xilin Gol League, Inner Mongolia, China. Since the implementation of this product, the purchasing rate has varied from region to region, as the highest purchasing rate was 84.

In-situ characterization of porcine fibroblasts in response to silver ions by Raman spectroscopy and liquid scanning transmission electron microscopy.

Since silver ion is known for its antimicrobial function, most of the research has focused mainly on toxicity effects rather than the role of silver ion in general biology and the behind mechanism of actions of silver ion in mammalian cells. Moreover, a conventional in vitro approach to estimate the effects of silver ion on cells does not provide information about the biochemical changes and might accompany artifacts due to invasive and destructive sample preparation processes. In the present study, in-situ real time approaches were applied to evaluate the impact of silver ion (0.

Effects of electrical biostimulation and silver ions on porcine fibroblast cells.

The medical applications of electrical biostimulation and silver ions have been evaluated in laboratory experiments and clinical studies for more than two decades. Their effects on preventing infection and promoting wound healing have been described. However, little is known about the role of electrical biostimulation and/or silver ion on changes in cellular transcriptome dynamics.

Expression and selective activation of somatostatin receptor subtypes induces cell cycle arrest in cancer cells.

Somatostatin receptors (SSTRs) are G-protein-coupled plasma membrane receptors that have been determined to be expressed in normal and cancer tissues. Activation of SSTRs frequently results in inhibition of cell proliferation and therefore somatostatin analogues (SSAs) have been used in cancer treatment. However, the variable outcomes of SSA treatment were considered to be the consequences of loss-of-expression of SSTRs and/or subtype-specific effects.

Isolation and characterization of trophoblast-derived stem-like cells from peri-implantation porcine embryos.

In mammals, the trophoblast lineage of the embryo is specified before attachment/implantation to become the fetal portion of the placenta. Trophoblast-derived cells were isolated and cultured from day 10 and day 13 porcine embryos and were grown in vitro in a defined, serum-free culture medium for over 2 years without showing any signs of senescence. However, trophoblast-derived cells placed into serum-containing medium rapidly senesce and fail to proliferate.

[Bioavailability of cadmium in seawater to Paralichthys olivaceus].

With exposure experiment, this paper studied the accumulation and elimination of cadmium (Cd) in the viscera, muscle and gill of Paralichthys olivaceus, and the effects of TOC concentration in seawater on the Cd accumulation. The results showed that when the exposure concentration of Cd was 0.5 mg x L(-1), its accumulation in test tissues increased with time, and reached equilibrium on the 10th day.
