The hepatic removal of triglyceride-rich chylomicrons during the postprandial phase represents an important step towards determining the bioavailability of dietary lipids amongst the peripheral tissues. Indeed, elevated postprandial lipemia is often associated with obesity and increased risk of coronary heart disease. The milk protein, lactoferrin, has been shown to inhibit ...

The evolution of convergent phenotypes is one of the most interesting outcomes of replicate adaptive radiations. Remarkable cases of convergence involve the thick-lipped phenotype found across cichlid species flocks in the East African Great Lakes. Unlike most other convergent forms in cichlids, which are restricted to East Africa, the thick-lipped ...

Hypercholesterolemia is a major risk factor for atherosclerosis and related occlusive vascular diseases. We investigated the effect of low-dose fluvastatin (2 mg kg(-1) day(-1) ) on antioxidant enzyme activities [superoxide dismutase (SOD), catalase], vascular reactivity changes and oxidatively induced DNA damage in early stage of atherosclerosis in hypercholesterolemic rabbits. The ...

The main sterol of the human cell membrane is cholesterol, whereas in yeast it is ergosterol. In this study, we constructed a cholesterol-producing yeast strain by disrupting the genes related to ergosterol synthesis and inserting the genes related to cholesterol synthesis. The total sterols of the mutant yeast were extracted ...

The ecology of mosquito vectors and malaria parasites affect the incidence, seasonal transmission and geographical range of malaria. Most malaria models to date assume constant or linear responses of mosquito and parasite life-history traits to temperature, predicting optimal transmission at 31 °C. These models are at odds with field observations of ...

Due to the possible risk of infusion reactions of rituximab (RTX), a slow infusion rate (total infusion time, 255 min) is suggested for rheumatological use. However, especially in oncology field, accelerated infusion of RTX is reported to be well tolerated and safe. The aim of our study was to evaluate whether ...

In this work, the extracellular decolorization of aniline blue, a sulfonated triphenylmethane dye, by Shewanella oneidensis MR-1 was confirmed. S. oneidensis MR-1 showed a high capacity for decolorizing aniline blue even at a concentration of up to 1,000 mg/l under anaerobic conditions. Maximum decolorization efficiency appeared at pH 7.0 and 30 °C. Lactate ...

Iron-overload cardiomyopathy is a major cause of death in thalassemic patients. However, pathways of non-transferrin-bound iron (NTBI) uptake into cardiomyocytes under iron-overload conditions are still controversial. We previously demonstrated that Fe(2+) uptake in thalassemic cardiomyocytes is mainly mediated by T-type calcium channels (TTCCs). However, direct evidence regarding Fe(3+) uptake, the ...

Direct visualization of co-translational folding of nascent polypeptide chains is challenging. Here we present, for the first time, AFM images of large protein constructs based on the membrane binding domain of ankyrin-R, complexed with the ribosome. The characteristic "horse-shoe" shape of ankyrin-R emerging from the ribosome was captured.

The O-acetylation of peptidoglycan in Gram-negative bacteria occurs specifically at the C-6 hydroxyl group of muramoyl residues. The level of peptidoglycan O-acetylation was found to decrease from 51% to 29% upon differentiation of Proteus mirabilis vegetative cells to swarmers. This decrease was accompanied by a change in the muropeptide composition ...
