Increasement of Cd adsorption capacity of rice stubble from being alive until death in a modified rice-fish system.

Soil heavy metal contamination is an increasingly urgent problem throughout the world. Phytoremediation is a cost-effective and ecologically friendly in situ method for the remediation of heavy metal contaminated soils. Rice has the potential for use in soil remediation due to its high biomass production, however, risks related to food safety and low accumulation potential exist.

Effects of cadmium pollution on the safety of rice and fish in a rice-fish coculture system.

The rice-fish coculture system (RFS) is one of the most important and environmentally friendly agricultural systems in the world. With the increasing amounts of heavy metal contamination in the soil and water, the safe production of RFS has been greatly threatened. However, there are no reports on heavy metal uptake by rice and fish in a RFS.

Synthesis and Antibacterial Evaluation of New Sulfone Derivatives Containing 2-Aroxymethyl-1,3,4-Oxadiazole/Thiadiazole Moiety.

Sulfones are one of the most important classes of agricultural fungicides. To discover new lead compounds with high antibacterial activity, a series of new sulfone derivatives were designed and synthesized by introducing the aroxymethyl moiety into the scaffold of 1,3,4-oxadiazole/thiadiazole sulfones. Antibacterial activities against three phytopathogens (, , .

Question about Liu Y et al. entitled "Effect of c-erbB2 overexpression on prognosis in osteosarcoma: evidence from eight studies".

We read with great interest on the recent paper by Liu Y et al. "Effect of c-erbB2 overexpression on prognosis in osteosarcoma: evidence from eight studies" published online in Tumor Biology (Tumor Biol 5(9):8939-43, 2014). The investigators (Liu Y et al.

Levofloxacin and proton pump inhibitor-based triple therapy versus standard triple first-line therapy for Helicobacter pylori eradication.

Background: Standard triple therapy for Helicobacter pylori infection fails in up to one quarter of patients. Levofloxacin-based triple therapy may be more efficacious.

Objective: The aim of this paper was to compare levofloxacin and proton pump inhibitor-based triple therapy with standard triple therapy for H.

[Effect of Qingkailing injection (QKLI) on complement and RBL-2 H3 cells in virto].

Objective: To investigate the effect of Qingkailing injection (QKLI) on complement and RBL-2 H3 cells in virto.

Method: The mixture of human serums and QKLI were incubated for 30 min in vitro and then the content of SC5 b-9 in the mixture was determined by ELISA. RBL-2 H3 cells were cultured and treated by QKLI.

[Study on the toxic reaction induced by single dose of qingkailing injection].

Objective: To study the toxic reaction induced by Qingkailing Injection.

Methods: Kunming mice were injected single dose of Qingkailing Injection via tail vein and observed for 14 days to test the toxic reaction of the drug. According to Chinese Pharmacopoeia, hemolysis tests were conducted on the injections of different lots and each ingredient of the injection.

[Optimization of ultrahigh pressure extraction for polydatin and resveratrol from Polygonum cuspidatum by using uniform design].

Objective: To optimize the ultrahigh pressure extraction (UPE) process of polydatin and resveratrol from Polygonum cuspidatum by using uniform design.

Method: On the basis of single factor screening, the uniform design was adopted for getting the optimal technique parameters. The optimum result of UPE was compared with conventional extractions.
