Effects of temperature on population growth and resting egg production of freshwater rotifer (Brachionus calyciflorus)

Resting egg production of rotifers provides critical advantages in larviculture of most fish species due to the reduction in the costs of labour and algae production. The study was conducted to investigate the effects of temperature on population growth and resting egg production of a freshwater rotifer, Brachionus calyciflorus, collected in Northern Vietnam.

Potential toxic heavy metal contamination of roadside soil

As the urban area has high population density and intensive anthropogenic activities, there are a great number of sources of heavy metals in cities, placing a considerable influence on human health. Emissions of heavy metals may come from domestic waste, chemical industry and transportation. These emissions have been continuously adding heavy metals to soils and they will remain present for many years even after the pollution sources have been removed.

Báo cáo khoa học: Mechanisms of obesity and related pathologies: Role of apolipoprotein E in the development of obesity

Apolipoprotein E is a polymorphic glycoprotein in humans with a molecu-lar mass of 34.5 kDa. It is a component of chylomicron remnants, very low density lipoprotein, low density lipoprotein and high density lipopro-tein, and is primarily responsible for maintaining plasma lipid homeostasis. In addition to these well-documented functions, recent studies in experi-mental mouse models, as well as population studies, show that apolipo-protein E also plays an important role in the development of obesity and insulin resistance. ...
