Streamer ionization fronts are pulled fronts propagating into a linearly unstable state; the spatial decay of the initial condition of a planar front selects dynamically one specific long time attractor out of a continuous family. A stability analysis for perturbations in the transverse direction has to take these features into account. In this paper we show how to apply the Evans function in a...
One of the major problems of electron microscopy of the central nervous system is to locate with precision the region involved in the degenerative process in grey or white matter. For this reason, the avian optic tectum was chosen to studythe effects of degeneration of axons and their terminals. Axon section is accomplished simply by unilateral removal of the eye so that the optic nerve afferen...
Objective(s): Neuroprotection is created following the inhibition of angiotensin II type 1 receptor (AT1R). Therefore, the purpose of this research was examining AT1R blockage by candesartan in diffuse traumatic brain injury (TBI). Materials and Methods: Male rats were assigned into sham, TBI, vehicle, and candesartan groups. Candesartan (0.3 mg/kg) or vehicle was administered IP, 30 min post-T...
In 1978, Gareth Evans published a short and somewhat cryptic
 article purporting to establish that there are no vague objects. This
 paper is commentary on this. Prima facie, the claim there
 objects clearly false. Mt Everest, for example, has no
 precise boundaries. And if this so, must be something wrong
 with Evans' argument. paper, I discuss what is, giving a

The cardiovascular effects of centrally administered cholinomimetics were examined in conscious Long-Evans and Brattleboro rats. Carbachol (1 microgram/kg) or physostigmine (50 micrograms/kg) induced a long-lasting increase in blood pressure and a decrease in heart rate in Long-Evans rats whereas no bradycardia was observed in Brattleboro rats, and the pressor response was significantly less th...
Introduction: Arterial hypertension is one of the causes of stroke, and as one of the vasculotoxic conditions intensifies ischemic stroke complications. The aim of the present study was to analyze the effects of short-term cerebral hypertension on ischemia/reperfusion injury and pathogenesis of ischemic stroke. Methods: The experiments were performed on three groups of rats (N=36) Sham, cont...
Background: In previous studies, the neuroprotective effect of 17&beta-estradiol in diffuse traumatic brain injury has been shown. This study used ICI 182,780, a non-selective estrogen receptor antagonist, to test the hypothesis that the neuroprotective effect of 17&beta-estradiol in traumatic brain injury is mediated by the estrogen receptors. Methods: The ovariectomized rats were divided into...
