endarterectomy (a procedure to remove plaque from the neck artery), peripheral vascularization (a type of angioplasty used to dilate narrowed arteries in the legs), or amputation. The risk of heart disease increased with high C-reactive protein leve...
Animal study demonstrates carbon monoxide may help heart patients
...r prior to inducing a "balloon-like injury" in the carotid
vessels of the mice, the development of arteriosclerotic lesions was reduced by 60 to 80 percent, compared with the animals that were not exposed to the gas. The "injury" that the researchers created resembled one which might develop in response to a...
Treating strokes with blood cord cells holds promise, Saint Louis University rat study shows
... from human umbilical cord blood into the internal carotid
artery of rats immediately after a stroke. The treatment improved sensorimotor function. "While we have a lot of work to do to go from a rat stroke model to treating patients, we are encouraged that human umbilical cell therapy may provide a potentia...
Could a specific protein contribute to erectile dysfunction for the diabetic and obese?
...e used. The animals were anesthetized and the left carotid
artery cannulated to continuously monitor the mean arterial pressure (MAP). The right corpus cavernosum was cannulated to permit continuous monitoring of intra-cavernosal pressure (ICP) and the left corpus cavernosum was cannulated to allow for admin...
Scripps scientists link ozone to atherosclerosis
... Clinic, and asked if they could obtain samples of carotid
atherosclerotic plaques. DeLaria provided a sample of plaque material from a patient who recently underwent an endarterectomy, generously enabling Wentworth, Lerner, and their colleagues to perform their studies. Endarterectomies are common surgical ...
New technique helps shed light on progression of dementia
...The researchers injected the microspheres into the carotid
arteries of one group of rats and a salt-water solution into the arteries of rats in a control group. Sarter and his colleagues used the microsphere model in order to look at loss of mental function in a normal, aging brain. Traditional animal models...
Novel therapies show promise against myeloid leukemia
...R-3 cancers. Interestingly, MSC injected into the carotid
artery of mice with malignant gliomas (incurable brain tumors) reproduced selectively in the tumors, and not in normal brain tissues. Tumor growth was inhibited by co-cultures of IFN-MSC and glioma cells in vitro, and injection of IFN-MSC directly i...

When blood can't get to brain, special CT scan helps
...ample, the blood flow in the area fed by a clogged carotid
artery on one side of the brain can be compared with the flow in an area fed by the other carotid
artery, on the opposite side of the brain. Clogs in the carotid
arteries are caused by the same cho...
Oxygen sensing in worms may hold key to healthy blood pressure in humans

body that sits at the fork of the carotid
artery. When there's even a small drop in oxygen concentrations, as might happen in vigorous exercis...
Why some neonates need caffeine
...tilation. Peripheral chemoreceptors, found in the carotid
and aortic bodies and stimulated by chemical changes in blood composition, provide feed-forward control of respiration, which can thus terminate apnea and initiate normal breathing. These receptors are believed to be an important target for caffeine ...
