Uptake and speciation of vanadium in the rhizosphere soils of rape (Brassica juncea L.).

The response of rape (Brassica juncea L.) to different vanadium (V) speciation in rhizosphere soils was investigated in pot experiments using an agricultural soil containing 147 mg V kg(-1) supplemented with 0-500 mg V kg(-1) of pentavalent V [V(V)] and a mining soil containing 774 mg V kg(-1). Tetravalent V [V(IV)] accounted for 76.

Bimetallic ruthenium complexes bridged by divinylphenylene bearing oligo(ethylene glycol)methylether: synthesis, (spectro)electrochemistry and the lithium cation effect.

A series of 1,4-disubstituted ruthenium-vinyl complexes, (E,E)-[{(PMe3)3(CO)ClRu}2(μ-HC=CH-Ar-CH=CH)], in which the 1,4-diethenylphenylene bridge bears two oligo(ethylene glycol)methyl ether side chains at different positions (2,5- and 2,3-positions), were prepared. The respective products were characterized by elemental analyses and NMR spectroscopy. The structures of complexes 1b and 1e were established by X-ray crystallography.

[Aspartate-ornithine granules in the treatment of nonalcoholic steatohepatitis: a multiple-dose parallel controlled clinical trial].

Objective: To investigate the therapeutic efficacy and safety of aspartate-ornithine granules in patients with nonalcoholic steatohepatitis (NASH).

Methods: Seventy-two patients with NASH were included in this multiple-dose parallel controlled clinical trial and received a 12-week course of aspartate-ornithine granule treatment at either high-dose (6 g bid po; n = 38) or low-dose (3 g bid po; n = 34). Clinical efficacy was assessed by monitoring data from urinalysis, serologic tests (alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), and triglyceride (TG)), and abdominal computed tomography (CT) scan.

[Expression of uncoupling protein 2 and its relationship to the content of adenosine triphosphate in the nonalcoholic fatty livers of rats fed a high-fat diet].

Objective: To investigate the expression of uncoupling protein 2 (UCP2) and its relationship to the content of adenosine triphosphate (ATP) in livers of nonalcoholic fatty liver disease (NAFLD) rats fed a fat-rich diet.

Methods: To produce a NAFLD model, a fat-rich diet, consisting of 10% lard oil + 2% cholesterol, was given to Sprague-Dawley rats for a period of 8, 12, 16 and 24 weeks. The normal control rats were fed normal diets.

[Dynamic changes of plasma levels of prostacycline and thromboxane A2 and their correlation with the severity of hepatic injury in rats with nonalcoholic fatty liver disease].

Objective: To investigate the dynamic changes of plasma levels of prostacycline (PGI2) and thromboxane A2 (TXA2) and their relationship with the severity of hepatic injury in rats with nonalcoholic fatty liver disease (NAFLD).

Methods: We established a NAFLD model, with a fat-rich diet consisting of 10% lard oil + 2% cholesterol, which was given to Sprague-Dawley rats (n=48) for a period of 8, 12, 16 and 24 weeks. The other rats were fed standard diets and were used as normal controls (n=24).

[Change of serum endotoxin level in the progress of nonalcoholic steatohepatitis in rats].

Objective: To explore the role of endotoxin in the pathogenesis of nonalcoholic steatohepatitis (NASH).

Methods: Rat models of NASH were established by giving a fat-riched diet. These rats were sacrificed at the 4th, 8th, 12th, 16th and 24th weeks during the study.
