The positive effect of phenylephrine (PE) on stroke volume (SV) was 3 to 5 times weaker in the rats exposed to hypokinesia for 30 days as compared to the controls. After obsidan blockade of beta-adrenoreceptors SV increased in both groups and the intergroup differences in the PE effect remained
Eye movements and spatial attention are closely related, and eye-tracking can provide valuable information in research on visual attention. We investigated the pathology of overt attention in right hemisphere (RH) stroke patients differing in their severity of neglect symptoms by using In the early postnatal period, high motor activity of young rats leads to an increase in the tonic effects of the sympathetic nerves and to a decrease in that of the vagus on the systolic blood volume.
Experiments on rat pups showed that regular exercise for 4 weeks starting from day 14 after birth considerably increased stroke volume. Similar dynamics of stroke volume was observed in subsequent period of restraint locomotion. Experimental hypokinesia starting from day 14 after birth significantly
OBJECTIVE
To study the clinical significance of the cardio-ankle vascular index (CAVI) in patients with stroke.
METHODS
The study included 374 post-stroke patients. The state of peripheral arteries was assessed using CAVI and the ankle-shoulder index (ASI).
CONCLUSIONS
The pathological CAVI (>9.0)
BACKGROUND
The knowledge about the natural history of stroke in Chagas disease is incomplete.
METHODS
Vascular risk factors and stroke subtypes of asymptomatic Trypanosoma cruzi-infected patients with no clinical evidence of heart failure were assessed. They were compared with chronic chagasic
BACKGROUND
Cardio embolism and cerebrovascular atherosclerosis are two major mechanisms of stroke. Studies investigating associations between advanced echocardiographic parameters and stroke mechanisms are limited.
METHODS
This study is a standardized review of 633 patients admitted to the stroke
BACKGROUND
Embolus is one of the causes of ischemic stroke that can be due to cardiac sources such as valvular heart diseases and atrial fibrillation and atheroma of the aorta. Transesophageal echocardiography (TEE) is superior in identifying potential cardiac sources of emboli. Due to insufficient
Background Cardiac features diverge in Asians; however, it is not known how these differences relate to embolic stroke of unknown source (ESUS) in Southeast Asian and Eastern Mediterranean regions. Methods and Results A retrospective analysis of prospectively collected acute ischemic stroke data
OBJECTIVE
Motor intentional disorders (MIDs) are characterized by dysfunction in the preparation, initiation, maintenance, and termination of goal-oriented actions. In this study, we investigated (1) whether patients with right hemisphere strokes (RHS) and left hemisphere strokes (LHS) differ in the
The effect of a constant magnetic field on central circulation of rats was investigated during their exposure to antiorthostatic hypokinesia. Circulation parameters were measured by impedance rheoplethysmography. It was found that 3-hour exposure to a 0.4 T magnetic field did not produce a
Recognizing drug-induced parkinsonian bradykinesia in psychosis patients can be challenging due to overlapping presentation with psychomotor slowing associated with depression, negative symptoms, or cognitive disturbances. In this study, we apply prior findings on the pathophysiology of bradykinesia
There are different etiologies of hemiparkinsonism. A few patients with hemiparkinsonism secondary to infarction in the contralateral substantia nigra have been reported in the literature, and only one of these patients presented with pure hemiparkinsonism. This paper reports the unusual case of a
Objectives. To find out cardiovascular risk factors and the effect of atherosclerotic lesions of carotid arteries on the level of disability of young and middle-aged patients to the end of the acute period of ischemic stroke (II). Material and methods. A study included 266 patients, aged from 25 to
Hypokinesia effects on cardiac contractivity and vegetative regulation were studied in rats with high and low spontaneous motor activity. It was shown that hypokinesia promotes depression of the stroke volume and decrease of sympathetic nervous activity in rats with low motor activity. At the same
