[Effects of Combined Application of Different Nitrogen Fertilizers and Biochar on Cadmium Uptake by Pakchoi ( L.) in Cadmium Contaminated Soil].

Nitrogen is an essential nutrient element for crop growth, and biochar is a good material for soil remediation. In this study, a pakchoi ( L.) pot experiment was conducted to investigate the effects of the combined application of three nitrogen fertilizers, including urea, ammonium sulfate, calcium nitrate, and biochar on pakchoi growth and cadmium (Cd) uptake from cropland soil contaminated by Cd.

Astaxanthin inhibiting oxidative stress damage of placental trophoblast cells in vitro.

Oxidative stress from the trophoblasts is one of the possible pathological mechanisms of Preeclampsia (PE). This study aimed at exploring the potential effects of astaxanthin (ATX) on oxidative stress damaged placental trophoblast cell line HTR-8/SVneo. Oxidative stress-induced damaged through HO treatment was checked by MTS CellTiter 96® cell viability, 2',7'-dichlorofluorescein diacetate (DCFH-DA) induced fluorescence, the level of the intracellular malondialdehyde (MDA), and the detection of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT).

[Genomic characteristics of coxsackievirus B1 MSH/KM9/2009 strain isolated in Yunnan, China].

To characterize the complete genome sequence of coxsackievirus B1 (CVB1) MSH/KM9/2009 strain isolated from Yunnan, China,2009. Eight overlapping clones covering the whole viral genome (excluding the poly-A tail) were obtained by RT-PCR and sequenced, and their nucleotide and amino acid sequences were compared with other known CVB1 strains. The genome of the CVB1 MSH/KM9/2009 strain had 7384 nucleotides in length, and contained a 741nt non-translated region (NTR) at the 5' end and a 94nt NTR at the 3' end.

[Complete genome sequence characteristics of human echovirus 9 strain isolated in Yunnan, China].

To analyze the genomic sequence characteristics of a human Echovirus 9(ECHO-9) strain isolated from a child with Hand-foot-mouth disease (HFMD) in Kunming, Yunnan Province, in 2010. The complete genome sequence of a human echovirus 9 strain, MSH-KM812-2010 was determined. As other human enterovirus, its genome was 7,424 nucleotides (nts) in length and encoded for 2,203 amino acids (aas).

[Complete nucleotide sequence of a human echovirus 6 strain KM57-09 isolated in Yunnan, China, in 2009].

Objective: To analyze the genetic characterization of the complete genome from a human echovirus 6 (Echo6) strain KM57-09 isolated in Yunnan, China, in 2009.

Methods: Using the RT-PCR, eight fragments containing about 1000 nucleotides which covered the whole viral genome were sequenced. The sequences were aligned with other reference enterovirus sequences downloaded from the GenBank, using Mega 5.

Surgical treatment of Budd-Chiari syndrome: analysis of 221 cases.

Background: Budd-Chiari syndrome (B-CS) refers to post-hepatic portal hypertension and/or inferior vena cava hypertension caused by obstruction of blood flow at the portal cardinal hepatic vein. The treatments of B-CS include operations on pathological membrane lesions, shunting and combined operations. Studies have shown that China, Japan, India and South Africa have a high incidence of B-CS.
