Effect of Artemisia annua on anticoccidial action, intestinal microbiota and metabolites of Hu lambs.

Background: Coccidia are among the primary pathogens causing diarrhea and even fatalities in lambs. With the increasing use of chemical drugs to treat coccidiosis, the problem of drug resistance is becoming more and more threatening. Therefore, there is an urgent need to identify novel alternative drugs for the treatment of the lamb coccidia.

Effects of fermented on the intestinal microbiota and metabolites of Hu lambs with naturally infected with spp.

Background: Sheep coccidiosis could disturb the balance of intestinal microbiota, causing diarrhea, and even death in lambs. Chemical drugs are the primary method of treating sheep coccidiosis, but their use will bring drug resistance, toxic side effects, drug residues, and other problems. Chinese herbal medicines are investigated as alternative methods for controlling coccidian infections.

Development and Clinical Application of a Molecular Assay for Four Common Porcine Enteroviruses.

Porcine epidemic diarrhea virus (PEDV), porcine transmissible gastroenteritis virus (TGEV), porcine deltacoronavirus (PDCoV), and porcine rotavirus-A (PoRVA) are the four main pathogens that cause viral diarrhea in pigs, and they often occur in mixed infections, which are difficult to distinguish only according to clinical symptoms. Here, we developed a multiplex TaqMan-probe-based real-time RT-PCR method for the simultaneous detection of PEDV, TGEV, PDCoV, and PoRVA for the first time. The specific primers and probes were designed for the M protein gene of PEDV, N protein gene of TGEV, N protein gene of PDCoV, and VP7 protein gene of PoRVA, and corresponding recombinant plasmids were constructed.

Impacts of a highly pathogenic ovine Eimeria ovinoidalis on the growth of Hu lambs.

The apicomplexan Eimeria ovinoidalis is distributed worldwide. It can cause clinical coccidiosis, which is one of the most pathogenic species in sheep, reducing growth rates and resulting in significant economic losses in the industry. Its principal clinical sign is profuse diarrhoea in young animals.

Freeze Metal Halide Perovskite for Dramatic Laser Tuning: Direct Observation via In Situ Cryo-Electron Microscope.

A frozen-temperature (below -28 °C) laser tuning way is developed to optimize metal halide perovskite (MHP)'s stability and opto-electronic properties, for emitter, photovoltaic and detector applications. Here freezing can adjust the competitive laser irradiation effects between damaging and annealing/repairing. And the ligand shells on MHP surface, which are widely present for many MHP materials, can be frozen and act as transparent solid templates for MHP's re-crystallization/re-growth during the laser tuning.

Efficient photodegradation of antibiotics by g-CN and 3D flower-like BiWO perovskite structure: Insights into the preparation, evaluation, and potential mechanism.

Antibiotics are emerging organic pollutants that have attracted huge attention owing to their abundant use and associated ecological threats. The aim of this study is to develop and use photocatalysts to degrade antibiotics, including tetracycline (TC), ciprofloxacin (CIP), and amoxicillin (AMOX). Therefore, a novel Z-scheme heterojunction composite of g-CN (gCN) and 3D flower-like BiWO (BW) perovskite structure was designed and developed, namely BiWO/g-CN (BW/gCN), which can degrade low-concentration of antibiotics in aquatic environments under visible light.

Portulaca oleracea exhibited anti-coccidian activity, fortified the gut microbiota of Hu lambs.

Coccidia of the genus Eimeria are important pathogens that cause coccidiosis in livestock and poultry. Due to the expansion of intensive farming, coccidiosis has become more difficult to control. In addition, the continued use of anti-coccidiosis drugs has led to drug resistance and residue.

Analyzing the effect of public private partnership mode on sewage treatment in China.

The public-private partnership (PPP) mode is one of the main ways to promote environmental governance through marketization in the sewage treatment industry. This mode is crucial for environmental protection and livelihood improvement. In order to investigate the impact of PPP mode on sewage treatment, the influence of financial development and the government-business relationship on the effectiveness of sewage treatment under PPP mode, and the role of government in this context, an empirical model is established.

Engineering Two-Dimensional Metal-Organic Framework on Molecular Basis for Fast Li Conduction.

Metal-organic frameworks (MOFs) have been proposed as emerging fillers for composite polymer electrolytes (CPEs). However, MOF particles are usually served as passive fillers that yield limited ionic conductivity improvement. Building continuous MOF reinforcements and exploiting their active roles remain challenging.

PD-L1 tumor-intrinsic signaling and its therapeutic implication in triple-negative breast cancer.

Although the immune checkpoint role of programmed death ligand 1 (PD-L1) has been established and targeted in cancer immunotherapy, the tumor-intrinsic role of PD-L1 is less appreciated in tumor biology and therapeutics development, partly because of the incomplete mechanistic understanding. Here we demonstrate a potentially novel mechanism by which PD-L1 promotes the epithelial-mesenchymal transition (EMT) in triple-negative breast cancer (TNBC) cells by suppressing the destruction of the EMT transcription factor Snail. PD-L1 directly binds to and inhibits the tyrosine phosphatase PTP1B, thus preserving p38-MAPK activity that phosphorylates and inhibits glycogen synthase kinase 3β (GSK3β).

The Role of Polymer and Inorganic Coatings to Enhance Interparticle Connections Diagnosed by Techniques.

Surface coating on alloy anodes renders an effective remedy to tolerate internal stress and alleviate the side reaction with electrolytes for long-lasting reversible lithium redox reactions in lithium-ion batteries. However, the role of surface coating on the interparticle connections of alloy anodes remains not fully understood. Herein, we exploit real-time lithiation and mechanic measurement of SnO nanoparticles via TEM with different coating layers, including conducting polymer polypyrrole and metal oxide MnO.

Three-Dimensional-Percolated Ceramic Nanoparticles along Natural-Cellulose-Derived Hierarchical Networks for High Li Conductivity and Mechanical Strength.

Solid polymer electrolytes for safe lithium batteries are in general flexible and easy to process, yet they have limited ionic conductivity and low mechanical strength. Introducing nano/microsized fillers into polymer electrolytes has been proven effective to address these issues, while formation of a percolated network of fillers for efficient Li conduction remains challenging. In this work, composite polymer electrolyte with 3D cellulose/ceramic networks is successfully developed using natural cellulose fibers and Li-conducting ceramic nanoparticles.

Li -Containing, Continuous Silica Nanofibers for High Li Conductivity in Composite Polymer Electrolyte.

Solid-state electrolytes have recently attracted significant attention toward safe and high-energy lithium chemistries. In particular, polyethylene oxide (PEO)-based composite polymer electrolytes (CPEs) have shown outstanding mechanical flexibility and manufacturing feasibility. However, their limited ionic conductivity, poor electrochemical stability, and insufficient mechanical strength are yet to be addressed.

Type Iγ phosphatidylinositol phosphate kinase dependent cell migration and invasion are dispensable for tumor metastasis.

Type Iγ phosphatidylinositol phosphate kinase (PIPKIγ) has been associated with poor prognosis in breast cancer patients by promoting metastasis. Among the six alternative-splicing isoforms of PIPKIγ, PIPKIγ_i2 specifically targets to focal adhesions and regulates focal adhesion turnover, thus was proposed responsible for tumor metastasis. In the present study, we specifically depleted PIPKIγ_i2 from mouse triple negative breast cancer (TNBC) 4T1 cells and analyzed their behaviors.
