Cabergoline possesses a beneficial effect on blood-brain barrier (BBB) integrity against lipopolysaccharide (LPS).

Sepsis is a disease induced by severe systemic inflammation and contributes to multiple acute organic dysfunctions. It is reported that disrupted blood-brain barrier (BBB) integrity is involved in sepsis-associated encephalopathy (SAE), which can be alleviated by repairing the damaged tight junction structure. Cabergoline is a specific dopamine D2 receptor agonist developed to treat Parkinson's disease and hyperprolactinemia and is reported to exert promising anti-inflammatory properties.

High-Curie Temperature Multilayered Hybrid Double Perovskite Photoferroelectrics Induced by Aromatic Cation Alloying.

Due to the breakthrough development of layered hybrid perovskites, the multilayered hybrid double perovskites have emerged as outstanding semiconducting materials owing to their environmental friendliness and superior stability. Despite recent booming advances, the realization of above-room temperature ferroelectricity in this fascinating family remains a huge challenge. Herein, when the molecular design strategy of aromatic cation alloying is applied, an above-room temperature "green" bilayered hybrid double perovskite photoferroelectric, (CHCHNH)CsAgBiBr (), is successfully developed with a notable saturation polarization of 10.

Giant room temperature electrocaloric effect in a layered hybrid perovskite ferroelectric: [(CH)CHCHNH]PbCl.

Electrocaloric effect driven by electric fields displays great potential in realizing highly efficient solid-state refrigeration. Nevertheless, most known electrocaloric materials exhibit relatively poor cooling performance near room temperature, which hinders their further applications. The emerging family of hybrid perovskite ferroelectrics, which exhibits superior structural diversity, large heat exchange and broad property tenability, offers an ideal platform.

Efficacy of quadruple regimen with polaprezinc for gastric infection eradication: protocol for a single-centre, single-blind, non-inferiority, randomised clinical trial.

Introduction: is the most well-known risk factor for gastric cancer. At present, shows varying levels of resistance to different treatments, leading to a lower rate of eradication. The aim of this study is to evaluate the efficacy of polaprezinc-containing quadruple therapy (PQT) for the eradication of infection and, thus, to provide more evidence to inform the clinical treatment of infection in China.

Skewed distribution of leaf color RGB model and application of skewed parameters in leaf color description model.

Background: Image processing techniques have been widely used in the analysis of leaf characteristics. Earlier techniques for processing digital RGB color images of plant leaves had several drawbacks, such as inadequate de-noising, and adopting normal-probability statistical estimation models which have few parameters and limited applicability.

Results: We confirmed the skewness distribution characteristics of the red, green, blue and grayscale channels of the images of tobacco leaves.

Proteomic analysis of tree peony (Paeonia ostii 'Feng Dan') seed germination affected by low temperature.

Seed germination is a critical process that is influenced by various factors. In the present study, the effect of low temperature (4 °C) on tree peony seed germination was investigated. Compared to seeds maintained at 25 °C, germination was inhibited when seeds were kept at 4 °C.

[Effects of exogenous α-naphthaleneacetic aid on the antioxidation system in soybean leaves subjected to long-term drought stress during flowering].

Two different drought tolerance soybean ( Glycine max) varieties (Nannong 99-6 and Kefeng 1) were used to study the effects of α-naphthaleneacetic acid (NAA) on the antioxidation system under long-term drought stress after flowering with pot experiment, which lasted for 110 days at Pailou Experiment Station, Nanjing Agricultural University, in 2012.
