Conducting polymer-coated MIL-101/S composite with scale-like shell structure for improving Li-S batteries.

Lithium-sulfur batteries are regarded as a promising energy storage system. However, they are plagued by rapid capacity decay, low coulombic efficiency, a severe shuttle effect and low sulfur loading in cathodes. To address these problems, effective carriers are highly demanded to encapsulate sulfur in order to extend the cycle life.

[Relationship between mannose-binding protein gene polymorphisms and disease progression and HBV DNA in patients with chronic HBV infection].

Objective: To determine the influences of Mannose binding protein (MBP) gene polymorphisms on HBV DNA loads and on the progression of liver disease in patients with chronic HBV infection.

Method: The Codons on 54 MBP gene polymorphisms and HBV DNA loads in a cohort of 395 patients with chronic HBV infection, including 244 with chronic hepatitis B (CHB), 151 with liver cirrhosis (LC) and 88 normal controls were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and fluorescent quantitative PCR (FQ-PCR).

Result: The MBP genotype frequencies of GGC/GAC and alleles genetic frequencies of GAC in CHB group showed no significant differences comparing to the normal control group (P > 0.
