Neurogenesis is a constitutive activity in the adult dentate gyrus whereby new cells are created in the subgranular zone, before becoming neurons in the dentate gyrus granule cell layer. New granule cells are thought to migrate from the subgranular zone outwards to the edge of the cell layer as they mature. In these experiments we examined the dendritic morphology of granule cells in the subgra...

Fuzzy information granulation transfers the time series analysis from numerical platform to granular platform, which enables us study at a different granularity. In previous studies, each fuzzy granule in can reflect average, range, and linear trend characteristics of data corresponding window. order get more general granule, this paper proposes polynomial granules, both nonlinear The distance ...

The interaction of soluble tyrosine hydroxylase with isolated chromaffin granule membranes was studied. The incubation of the granule membranes with the soluble fraction in the mixture that may approximate the intracellular environment of the resting cell resulted in a marked increase in the enzyme activity recovered in the membrane fraction, and enzyme activity precipitated with the granule me...

background and objectives: toxoplasma gondii is an obligatory intracellular parasite which causes severe diseases in the fetus of pregnant women and immunocopmromised patients. serological tests based on recombinant protein are one of the main diagnosis methods for the detection of specific antibodies in serum samples. dense granule antigenic proteins derived from t. gondii (tggras) are potenti...

abstract in order to optimum utilization of diazinon on rice stem borer, chilo suppressalis walker (lepidoptera: pyralidae), an experiment was conducted with two factors including, rice varieties (tarom-mahalli, khazar, nemat) and application times (control with no application, first generation application, second generation application, first and second generations application and four times a...

–In order to determine whether granule cell death stimulates the proliferation of granule cell precursors in the dentate gyrus of the adult rat, we performed both excitotoxic and mechanical lesions of the granule cell layer and examined the numbers of proliferating cells at different survival times. Using [H]thymidine autoradiography, bromodeoxyuridine labelling and proliferating cell nuclear a...

The brain is composed of diverse types of neurons that fulfill distinct roles in neuronal circuits, as manifested by the hippocampus, where pyramidal neurons and granule cells constitute functionally distinct domains: cornu ammonis (CA) and dentate gyrus (DG), respectively. Little is known about how these two types of neuron differentiate during hippocampal development, although a set of transc...

The antimicrobial mechanisms of rat polymorphonuclear leukocyte granule extract and isolated extract fractions against Acinetobacter calcoaceticus were examined. Crude granule extract and a fraction containing low-molecular-weight cationic peptides (peak D) reduced the viability of A. calcoaceticus and inhibited the uptake of radiolabeled macromolecule precursors by cells. The inhibitory activi...

The dentate gyrus produces new granule neurons throughout adulthood in mammals from rodents to humans. During granule cell maturation, defined markers are expressed in a highly regulated sequential process, which is necessary for directed neuronal differentiation. In the present study, we show that α-amino-3-hydroxy-5-methy-4-isoxazole propionate (AMPA) receptor subunits GluR1 and GluR2 are exp...
