due to the worldwide increase in the number of older people in both developed and developing countries, there is a public health concern for dealing with age related diseases such as neurodegenerative diseases. there is little known about the difference in neuronal cell responses between genders. our understanding of the neuronal cell response regarding genders, will be useful for developing mo...

Proof that plants possess homologs of animal adhesion proteins is lacking. In this paper we describe the generation of monoclonal antibodies that interfere with cell-cell contacts in the 4-cell embryo of the multicellular alga Volvox carteri, resulting in a hole between the cells. The number of following cell divisions is reduced and the cell division pattern is altered drastically. Antibodies ...

The growth, cellular total lipids, bioaccumulation amount, and bioaccumulation factors (BAFs) of 2,4,4'-tribromodiphenyl ether (BDE28), 2,2',4,4'-tetrabromodiphenyl ether (BDE47), and 2,2',4,4',5-pentabromodiphenyl ether (BDE99) in a semi-continuous culture of Prorocentrum donghaiense were studied in relation to nitrate (0, 128, and 512 micromol/L) and phosphate (0, 8, and 32 micromol/L) concen...

The use of mathematical models to study cardiac electrophysiology has a long history, and numerous cellular scale models are now available, covering a range of species and cell types. Their use to study emergent properties in tissue is also widespread, typically using the monodomain or bidomain equations coupled to one or more cell models. Despite the relative maturity of this field, little has...

The deposition of a Skeletonerna bloom onto sediment collected in a coastal bay was simulated and the effects on 02, N and P fluxes were recorded. A comparison of calculated net production and observed net efflux of inorganic nitrogen (IN = ammonium + nitrate) for the period prior to the addition of algae, indicated that two-thirds of the produced ammonium was nitrified and subsequently denitri...

The increase of copper oxide nanoparticle (CuO-NP) utilization in industry during recent years has resulted in their entry into aquatic ecosystems. In light of this fact, we have studied the toxicity of CuO-NPs at various concentrations on Chlorella vulgaris using an algal growth inhibition test (OECD201). Chlorella vulgaris was grown in positive Zander (Z-8 + N) media in a growth chamber. Afte...
