Seven new species are described and fully illustrated: Pseudognaptodon sinensis Tan van Achterberg, sp. n.

Review of the -group (Braconidae, Alysiinae, Alysiini), with description of a new genus and a new subgenus.

The world genera of the -group of Alysiini (Braconidae: Alysiinae) are reviewed and keyed. A new genus ( ) is proposed for Fischer, 2006, from Ecuador. One new subgenus ( ; type species Separatatus (Parabobekoides) yinshani from NW China) is described and illustrated.

Antioxidative systems, metal ion homeostasis and cadmium distribution in Iris lactea exposed to cadmium stress.

Iris lactea is a perennial halophyte and is tolerant to Cd. However, the mechanisms underlying this Cd tolerance are still poorly understood. In this study, morphological, physiological and biochemical responses of I.

[Dynamic changes of TGF-α and TGF-β1 in rats with liver cirrhosis induced by multiple pathogenic factors].

Objective: To explore the dynamic changes of transforming growth factor-α (TGF-α) and transforming growth factor-β1 (TGF-β1) of liver cirrhosis induced by multiple pathogenic factors in rats.

Methods: Animals in the cirrhosis group were fed a mixture of maize flour, lard, cholesterol and alcohol plus subcutaneously injection with carbon tetrachloride (CCl₄), the CCl₄(0.5 ml/100 g · w) was injected at the first day of experiment and the 40% CCl₄oil solution (0.

Effect of artesunate supplementation on bacterial translocation and dysbiosis of gut microbiota in rats with liver cirrhosis.

Aim: To evaluate the effect of artesunate (AS) supplementation on bacterial translocation (BT) and gut microbiota in a rat model of liver cirrhosis.

Methods: Fifty-four male Sprague-Dawley rats were randomly divided into a normal control group (N), a liver cirrhosis group (M) and a liver cirrhosis group intervened with AS (MA). Each group was sampled at 4, 6 and 8 wk.

Cloning and Transformation of EeHKT1;4 Gene from Elytrigia elongata.

The EeHKT1;4 gene was firstly cloned from Elytrigia elongata by RT-PCR technique with 1977 bp full-length cDNA encoding 1722 bp open reading frame (ORF) and 573 amino acids. The PCR fragment of EeHKT1;4 gene was inserted into the binary vector pBI121 and got the resulted expression vector, which named pBI121-35S-EeHKT1;4-Nos. The vector was further transformed into the agrobacterium EHA105, and then EeHKT1;4 gene was transferred into tobacco by the Agrobaterium- mediated genetic transformation method.

[Protective effect of tanshinol on the hepatopulmonary syndrome in rat].

Objective: To explore the mechanism of tanshinol on alleviate the inflammatory injury of lung tissue in rat hepatopulmonary syndrome (HPS).

Methods: SD rats were randomly divided into normal control group (n = 8), hepatopulmonary syndrome (HPS) group (n = 11) and tanshinol intervention group (n = 9). HE staining was used to observe the histopathology changes of pulmonary and hepatic tissues, and to count the number of macrophages in lung tissues.

[Effect of ischemic postconditioning on the expression of myocardium matrix metalloproteinase-2 induced by ischemia/reperfusion in rats].

Objective: To investigate the effect of ischemic postconditioning on the expression of rat myocardium matris metalloproteinase-2 (MMP-2) induced by ischemia/reperfusion (I/R) and relationship between its expression and interstitium and the effect on left ventricular function.

Methods: Twenty-four rats were randomly divided into 3 groups (n = 8): sham control (SC) group, ischemic/reperfusion (I/R) group and ischemic postconditioning (IPTC) group. The left ventricular peak systolic pressure and its derivate (+/- dp/dt) were calculated; The amount of myocardium collagenous were determined; The vitality of superoxide dismutase (SOD) and content of malondialdehyde (MDA) of plasma were detected; The activity of myocardium MMP-2 was measured by Western blot and RT-PCR.

Insulin-like growth factor binding protein-related protein 1 contributes to hepatic fibrogenesis.

Objective: The aim of this study was to investigate the role of insulin-like growth factor binding protein-related protein 1 (IGFBP-rP1) in the development of hepatic fibrogenesis in experimental disease models and human liver samples.

Methods: Cellular distribution patterns of IGFBP-rP1 were assessed by immunohistochemistry in fibrotic and cirrhotic human liver specimens. Gene silencing of IGFBP-rP1 was performed on cultured hepatic stellate cells (HSCs) by small interfering RNA (siRNA), and the silencing effect was determined by quantitative real-time polymerase chain reaction (PCR) and Western blot.
