Adsorption kinetics of heptadecafluoro-1-nonanol: Phase transition and mixed control.

Hypothesis: The adsorption kinetics of heptadecafluoro-1-nonanol (CHFOH) onto a clean air-water interface at low surfactant concentrations (equilibrium surface tension, γ(C) > 65 mN/m) has been reported, and the controlling mechanism was found to be mixed diffusive-kinetic controlled (Kuo et al., JCIS 402 (2013) 131). However, it remains to be determined what the adsorption kinetics are at higher concentrations.

The bioconcentration ability of heavy metal research for 50 kinds of rice under the same test conditions.

The aims of this experiment are to explore the accumulation of metal contamination of different varieties of rice planted in paddy fields and to provide a basis for the further research. The rice specimens were grown in and collected from a total area of 8.24 acres of rice planting fields where local farmers cultivated 50 different kinds of rice.

[Effects of lycopene on blood lipid and red blood cell of rat with hypercholesterolemia].

Objective: To study the effect of lycopene on red blood cell and the level of blood lipid.

Methods: According to the level of serum total cholesterol and weight, forty-eight adult male SD rats were divided randomly into six groups: normal control (group A), fed by normal feed; hyperlipidemia group (group B): fed by high fat diet; positive control group (group C): fed by high fat diet plus 10 mg * kg(-1) * d(-1) fluvastatin sodium; lycopene groups: fed by high fat diet plus 11 (group D), 22 (group E), 44 mg * kg(-1) * d(-1) (group F) lycopene through gavage, respectively. For all six groups, the level of serum total cholesterol (TC) and total triglyceride (TG) were measured at the end of 0, 1, 3 weeks of the study by taking samples from tail vein.

Comparison of lycopene and fluvastatin effects on atherosclerosis induced by a high-fat diet in rabbits.

Objective: We evaluated the antiatherogenic effect of lycopene in rabbits fed a high-fat diet.

Methods: Forty adult male rabbits were divided into five groups that were fed a standard diet, a high-fat diet, a high-fat diet plus 4 mg/kg of lycopene, a high-fat diet plus 12 mg/kg of lycopene, and a high-fat diet plus 10 mg/kg of fluvastatin, respectively. Lycopene and fluvastatin were administered intragastrically.

Impact of rosiglitazone on the expression of beta3-AR in the stable cell lines expressed beta3-AR gene.

Background: The aim of the present study was to investigate the effect of rosiglitazone, a peroxisome proliferator-activated receptor gamma2 (PPAR-gamma2) agonist, on the expression of beta3-adrenergic receptor (beta3-AR) at transcriptional and translational level.

Methods: We cloned the cDNA sequences of human PPAR-gamma2 (hPPAR-gamma2) gene and human wild type and mutant beta3-adrenergic receptor (hbeta3-AR) genes and established their eukaryotic expression vectors. The pcDNA3.

Histamine induces the expression of uncoupling protein 2 (UCP2) and acid-binding protein (aP2) in white adipocytes.

Background: The aim of the present study was to investigate whether histamine induces up-regulated expression of uncoupling protein 2 (UCP2) and fat acid-binding protein (aP2) in white adipocytes (differentiated 3T3-L1 cells).

Methods: Differentiation of 3T3-L1 preadipocytes to adipocytes was induced by the addition of 5 microg/mL insulin, 1 micromol/L dexamethasone, 10 mmol/L 1-isobutyl-3-methylxanthine, 1% dimethylsulfoxide, and 10% fetal bovine serum in Dulbecco's modification of Eagle's medium. Total RNA from differentiated 3T3-L1 cells was extracted and semi-quantitative RT-PCR was performed to determine the levels of UCP2 and aP2 mRNA.

Distributive characteristics of Ser49Gly and Gly389Arg genetic polymorphisms of beta1-adrenoceptor in Chinese Han and Dai populations.

Aim: Genetic polymorphisms causing Ser49Gly and Gly389Arg mutants of beta(1)-adrenoceptor may result in significant changes in the function of this receptor. The aim of the present study was to investigate the frequencies of the Ser49Gly and Gly389Arg mutant alleles in healthy Chinese populations and to investigate the differences between 2 Chinese ethnic groups (Han and Dai populations) with respect to the frequencies of these alleles.

Methods: A total of 225 Han Chinese and 175 Dai Chinese unrelated healthy volunteers were recruited for this study.
