background: alzheimer’s disease was known as a progressive neurodegenerative disorder in the elderly and is characterized by dementia and severe neuronal loss in the some regions of brain such as nucleus basalis magnocellularis. it plays an important role in the brain functions such as learning and memory. loss of cholinergic neurons of nucleus basalis magnocellularis by ibotenic acid can commo...

background: mediodorsal (md) thalamic nucleus, which is considered to take place between extra pyramidal and limbic feedback circuit, receives projective fibers from ventrolateral neurons of reticular part of substantia nigra (snr). in order to better understand the influence and chemical reaction of these fibers upon md nucleus, the morphology and synaptology of them were examined in the prese...

introduction: 17β-estradiol modulates nociception by binding to estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and gabaa receptors. beside its autonomic functions, paragigantocellularis lateralis (lpgi) nucleus is also involved in pain modulation. the aim of the current study was to investigate the role of the intracellular estrogenic ...

Algal species which are ubiquitous along the coastlines of many countries reflect the environmental conditions of the coastal seawater and may serve as useful biomonitors of anthropogenic pollution. Heavy metal concentrations of ten elements (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) of potential environmental concern were determined in seawater, sediments and twelve species of benthic marine ...

We present a scattering model for nuclei with similar masses. In this three-body model, the projectile has core+valence structure, whereas target is identical to core nucleus. The wave functions must be symmetrized exchange of cores. This property gives rise non-local potentials, which are computed without approximation. an extension Continuum Discretized Coupled Channel (CDCC) formalism, addit...

objective(s): the dopamine level of the nucleus accumbens changes during some stereotyped behaviors. to study dopamine level of the nucleus accumbens in intra infralimbic apomorphine-induced climbing, microdialysis probes were implanted into the nucleus accumbens shell of male sprague dawley rats weighting 275–400 g.   materials and methods: the rats were divided into two groups (apomorphine an...

background: benzene is one of the important occupational pollutants. there are some reports about the leukemogenic effects related to low-level exposure to benzene. objective: to study the frequency of micronucleus (mn), nucleoplasmic bridge (nb), and nuclear budding (nbud) in the peripheral blood lymphocytes of petrochemical workers with low level exposure to benzene. methods: we enrolled 50 w...
