Blood Vessel News and Research

RSS

Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.

Tips offered in April 2010 issue of American Journal Of Pathology

A group led by Dr. Massimo Loda at the Dana Farber Cancer Institute, Boston, MA has generated a preclinical model of human prostate cancer that mimics the genetic and growth behavior of primary tumors. Their report can be found in the April 2010 issue of the American Journal of Pathology.

Bergen research group adopts nanotechnology for cancer research

Professor James Lorens and his team at the University of Bergen's Department of Biomedicine are using nanotechnology to study how to make cells form new blood vessels, both within the patient's body and in the laboratory. In the next phase the team will use this knowledge to investigate the molecular mechanisms that govern the progression of cancer.

Children with neurofibromatosis more likely to have cardiovascular problems

Researchers have discovered how a genetic disease known mainly for its life-threatening tumors also can cause sudden death from cardiovascular disease in children, and are mounting a clinical trial to develop treatments for the problem.

Study shows that steroids target hemangioma stem cells

Hemangiomas -- strawberry-like birthmarks that commonly develop in early infancy - are generally harmless, but up to 10 percent cause tissue distortion or destruction and sometimes obstruction of vision or breathing. Since the 1960s, problematic hemangiomas have been treated with corticosteroids such as dexamethasone or prednisone.

Bailout stenting successful treatment for infants with constricted aortas

Cardiac interventionalists and surgeons at University Clinic in Leuven, Belgium have achieved successful stent implantation and follow-up coarctectomy in premature infants suffering from aortic coarctation. Full findings are published in the March issue of Catheterization and Cardiovascular Interventions, the official journal of The Society for Cardiovascular Angiography and Interventions.

Modulating body's inflammatory response may help fight serious infection

Treating virulent influenza, sepsis, and other potentially deadly infections long has focused on looking for ways to kill viruses and bacteria. But new research from the University of Utah and Utah State University shows that modulating the body's own overeager inflammatory response to infection may help save more lives.

Bone marrow stem cells offer potential treatment for patients with peripheral arterial disease

Bone marrow stem cells suspended in X-ray-visible microbubbles dramatically improve the body's ability to build new blood vessels in the upper leg-providing a potential future treatment for those with peripheral arterial disease or PAD, say researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla.

New clinical guidelines: Early diagnosis and treatment of TAD can save lives

When actor John Ritter died suddenly in 2003 from a tear in his thoracic aorta-the large artery that carries blood from the heart to the rest of the body-that tragedy brought attention to a rare but deadly condition that takes the lives of an estimated 10,000 Americans each year.

Novel procedure opens door to new and future treatment for pancreatic cancer

Pancreatic cancer-known as the most fatal cancer with no known effective treatment-requires a radical new therapy. A promising approach may come in the form of tiny gold nanoparticles-loaded with a therapeutic agent to kill cancer-in a novel procedure called "nanoembolization," said researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla.

Study suggests HuR gene plays a critical role in inducing cells' inflammatory response

To understand the role of inflammation in cardiovascular and other diseases, it is essential to identify and characterize genes that induce an inflammatory response in the body -- and the genes that regulate them.

Vitamin D supplements might do more harm than good for African-American patients

Vitamin D is quickly becoming the "go-to" remedy for treating a wide range of illnesses, from osteoporosis to atherosclerosis. However, new evidence from a Wake Forest University School of Medicine study suggests that supplementing vitamin D in those with low levels may have different effects based on patient race and, in black individuals, the supplement could actually do harm.

New cerebral protection device prevents stroke during treatment to clear blocked carotid arteries

An important interventional radiology advancement-the use of a new cerebral protection device in combination with FDA-approved carotid stents in high-surgical-risk patients-provides a minimally invasive, safe and effective way to prevent stroke from occurring during treatment to clear blocked carotid arteries, according to research released at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla.

Drug-eluting stents offer new hope to patients with critical limb ischemia

In the United States, more than 100,000 amputations are performed each year on individuals with critical limb ischemia, the most severe form of peripheral arterial disease (PAD). The number one priority in treating these patients is to re-establish blood flow to avoid limb amputation.

McKesson’s Horizon Cardiology CVIS simplifies complex cardiovascular processes

Recognizing that a single database cardiovascular information solution (CVIS) can streamline workflow and improve staff efficiency in the cardiology department, hospitals across North America are replacing their legacy hemodynamic systems with McKesson’s Horizon Cardiology CVIS. Through combining hemodynamic monitoring, ECG Management, and multi-modality imaging and reporting in a single database, Horizon Cardiology CVIS enables cardiologists to address today’s challenges of decreasing revenues, increasing costs and mounting documentation requirements.

Study finds new way to reduce risk of life-threatening bloodstream infections in newborns

Hospitals may reduce the risk of life-threatening bloodstream infections in newborns with peripherally inserted central venous catheters by replacing the device every 30 days or so, according to a new Johns Hopkins Children's Center study.

Military surgeons update management of high-energy knee injuries

The ongoing wars in Iraq and Afghanistan have resulted in uniquely destructive patterns of combat injuries, including limb-threatening injuries to the knee. In the March special issue of Techniques in Knee Surgery military surgeons serving in Operation Iraqi Freedom and Operation Enduring Freedom share their experience with managing these high-energy injuries of the knee. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health, a leading provider of information and business intelligence for students, professionals, and institutions in medicine, nursing, allied health, and pharmacy.

VEGF-B protein can control levels of FATPs in vascular wall: Study

A new study from the Swedish medical university Karolinska Institutet shows that the blood vessels and muscles of the heart can regulate the uptake of fatty acids that we ingest through meat, milk products and other food. The researchers behind the study have also identified the way in which regulation is governed by the muscles themselves.

Nanoparticles provide a targeted version of photothermal therapy for cancer

In a lecture he delivered in 1906, the German physician Paul Ehrlich coined the term Zuberkugel, or "magic bullet," as shorthand for a highly targeted medical treatment.

Extreme or moderate heat may help cure malignant and benign tumors

Aided by ultrasound guidance, treating tumors with extreme heat or moderate heat may provide a possible therapeutic option, according to early research presented at the second AACR Dead Sea International Conference on Advances in Cancer Research: From the Laboratory to the Clinic, held March 7-10, 2010.
