Body fat percentage is a major determinant of total bilirubin independently of UGT1A1*28 polymorphism in young obese.

Luís Belo et al.

PloS one, 9(6), e98467-e98467 (2014-06-06)

Bilirubin has potential antioxidant and anti-inflammatory properties. The UGT1A1*28 polymorphism (TA repeats in the promoter region) is a major determinant of bilirubin levels and recent evidence suggests that raised adiposity may also be a contributing factor. We aimed to study

IL10A genotypic association with decreased IL-10 circulating levels in malaria infected individuals from endemic area of the Brazilian Amazon.

Virginia A Pereira et al.

Malaria journal, 14, 30-30 (2015-01-30)

Cytokines play an important role in human immune responses to malaria and variation in their production may influence the course of infection and determine the outcome of the disease. The differential production of cytokines has been linked to single nucleotide

Synthesis of hollow mesoporous silica nanoparticles with tunable shell thickness and pore size using amphiphilic block copolymers as core templates.

Xiaojun Zhou et al.

Dalton transactions (Cambridge, England : 2003), 43(31), 11834-11842 (2014-06-25)

This paper presents a facile method for the fabrication of uniform hollow mesoporous silica nanoparticles (HMSNs) with tunable shell thickness and pore size. In this method, a series of amphiphilic block copolymers of polystyrene-b-poly (acrylic acid) (PS-b-PAA) with different hydrophobic

Successive determination of urinary bilirubin and creatinine employing simultaneous injection effective mixing flow analysis.

Kraingkrai Ponhong et al.

Talanta, 133, 71-76 (2014-12-02)

A novel four-channel simultaneous injection effective mixing flow analysis (SIEMA) system has been assembled for successive determination of bilirubin and creatinine in urinary samples. The chemical variables and physical parameters in the flow system were optimized for the enhancement of

Intracellular generation of ROS by 3,5-dimethylaminophenol: persistence, cellular response, and impact of molecular toxicity.

Ming-Wei Chao et al.

Toxicological sciences : an official journal of the Society of Toxicology, 141(1), 300-313 (2014-06-29)

Epidemiological studies have demonstrated extensive human exposure to the monocyclic aromatic amines, particularly to 3,5-dimethylaniline, and found an association between exposure to these compounds and risk for bladder cancer. Little is known about molecular mechanisms that might lead to the
