Iatrogenic neurological deficit constitutes the greatest risk during therapeutic embolization in the vascular territories of the carotid and vertebral arteries. Constant monitoring of the patient's neurological status is therefore essential. The authors discuss the use of medical hypnosis to circumvent general anesthesia and to reduce chemical sedation to a minimum. Their experience with this technique is presented.

This study aimed at investigating the Bispectral Index (BIS) profile during carotid cross clamping (CXC). The study involved a pilot group of 10 patients undergoing routine carotid endarterectomy with shunt insertion under total intravenous anesthesia, and a study group of 26 additional patients. In all patients, rates of propofol and remifentanil providing a steady-state level of hypnosis (BIS: 40-60) were maintained constant throughout a recording period ranging from 3 minutes before CXC to shunt insertion.

OBJECTIVE: To investigate the association of urinary albumin excretion rate (UAER) and hyperuricemia with macrovascular atherosclerosis in type 2 diabetic patients. METHODS: Ninety-seven type 2 diabetic patients were divided into two groups according to the UAER, namely group A with UAER between 20 and 200 microg/min (n=63) and group B with UAER > or = 200 microg/min (n=34); the patients were also classified into hyperuricemia group (group C, n=59) and normal blood uric acid (BUA) group (group D, n=38).

Objective of this study was to develop a novel in vitro artery culture system to study vascular smooth muscle cell (SMC) proliferation of porcine carotid arteries in response to injury, basic fibroblast growth factor (FGF2), and FGF2 conjugated with cytotoxin saporin (SAP). Perfusion-cultured porcine carotid arteries remained contractile in response to norepinephrine and relaxant to acetylcholine for up to 96 h. SMC proliferation of cultured arteries was detected by bromodeoxyuridine incorporation in both non-injured and balloon-injured arteries.

OBJECTIVES: The objective of this prospective, single-site, 2-year dietary intervention study was to evaluate the effects of moderate weight reduction and subsequent partial weight regain on cardiovascular structure and function. BACKGROUND: Obesity is associated with adverse cardiac and vascular structural and functional alterations. METHODS: Sixty obese subjects (age 46 + or - 10 years, body mass index 37 + or - 3 kg/m(2)) were evaluated during their participation in a weight loss study.

The stable 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced hemiparkinsonian (HP) rhesus monkey model of Parkinson's disease (PD) has been frequently used to test preclinical experimental therapeutics targeted to treat patients with advanced PD who suffer from motor fluctuations and drug-induced dyskinesias. We retrospectively analyzed data from 17 stable HP rhesus monkeys treated long-term with chronic intermittent dosing of levodopa (LD) in an attempt to induce choreoathetoid and dystonic dyskinesias.

There is strong evidence showing that aging is associated with vascular oxidative stress, which has been causally linked to the development of cardiovascular diseases. NF-E2-related factor-2 (Nrf2) is a transcription factor, which is activated by reactive oxygen species in the vasculature of young animals leading to the upregulation of various antioxidant genes. The present study was designed to elucidate age-related changes in the homeostatic role of Nrf2-driven free radical detoxification mechanisms in the vasculature.

Aging promotes oxidative stress in vascular endothelial and smooth muscle cells, which contribute to the development of cardiovascular diseases. NF-E2-related factor 2 (Nrf2) is a transcription factor, which is activated by reactive oxygen species in the vasculature of young animals, leading to adaptive upregulation of numerous reactive oxygen species detoxifying and antioxidant genes. The present study was designed to elucidate age-associated changes in the homeostatic role of Nrf2-driven free radical detoxification mechanisms in the vasculature of nonhuman primates.

The presence of pericytes in brain regions undergoing repair is evident of the recruitment of bone marrow-derived multipotent regenerative cells to the neurovascular unit during angiogenesis. At present, post mortem sampling is the only way to identify them. Therefore, such cell typing is inadequate for preserving neural progenitor cells for any meaningful stem cell therapy. We aimed to target cerebral pericytes in vivo using dual gene transcript-targeted MRI (GT-tMRI) in male C57black6 mice after a 60-min bilateral carotid artery occlusion (BCAO).
