Presents abstracts of papers featured in the "Journal of Neurochemistry" that deal with proliferation, survival and differentiation processes in cells. "Influence of prenatal irradiation by 131-I on the heparin-binding activity of newborn rat brain proteins"; Cannabinoid inhibition of neuronal differentiation".

The article presents abstracts of research papers about mitochondrial neuochemistry. They include "Mitochondrial heterogeneity in brain," "Brain mitochondrial dysfunction—the critical event in neurodegeneration?," "Differential responses of astrocyte and neuronal mitochondria to calcium and oxidative stress," and "Proapoptotic mitochondrial signaling: the hows and whens."

The article presents an abstract of the medical research paper "Blood Platelets As Indicator of Disturbances of Acetyl-COA Metabolism in Diabetic Brain Neurons." The paper will be discussed at the Seventeenth Biennial Meeting of the International Society for Neurochemistry (ISN) and the Thirteenth General Meeting of the European Society for Neurochemistry (ESN) to be held in Berlin, Germany from August 8-14, 1999.

The article presents an abstract of the medical research paper "An Integrated Neuron-Glia Dialogue in the Processing of Brain Formation." The paper will be discussed at the Seventeenth Biennial Meeting of the International Society for Neurochemistry (ISN) and the Thirteenth General Meeting of the European Society for Neurochemistry (ESN) to be held in Berlin, Germany from August 8-14, 1999. The paper will discuss the role of astrocytes in the processing of brain formation.

The article presents an abstract of the medical research paper "Mouse Brain Neurons and Oligodendrocytes Express a Novel PLP/DM-20-Related Product." This paper is to be discussed in the Seventeenth Biennial Meeting of the International Society for Neurochemistry (ISN) and the Thirteenth General Meeting of the European Society for Neurochemistry (ESN) to be held at Berlin, Germany from August 8-14, 1999. This paper informs that PLP/DM-20 gene appears to be expressed in selected neurons.

The article presents an abstract of the research paper "Development of Rat Serotonergic Neurons from Various Raphe Subregions in Serum-Free Culture." The study determines a differential pattern in the development of the functional equipment in the various subgroups of serotonergic neurons. It determines that the serotonergic system is one of the earliest developing neurotransmitter systems in the mammalian brain.

The article presents an abstract of a research paper analyzing the levels of DNA polymerases in aging rat brain cells. Isolated neurons and astroglia from cerebral cortex of inbred Wistar rats of three ages: 4 days, 6 months and 2 years, were suspended in extraction buffer and sonicated. From the results at all ages studied and in both types of brain cells, β polymerase appears to be the predominant one although other DNA-polymerases seem to be present in reasonable amounts.
