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.

Environmental enrichment increases endogenous cell migration, facilitates functional repair

A team of Korean researchers investigated whether "environmental enrichment" can improve the neurobehavioral function of six week-old mice after transplantation of adipose-derived stem cells to treat hypoxic-ischemic brain injury, and found that brain repair (neurogenesis) was aided in some animals through exercise-induced fibroblast growth factor 2 (FGF2), a strong pro-angiogenic factor.

Researchers complete phase II clinical trial of dasatinib for patients with higher-risk MDS

Researchers at Moffitt Cancer Center have completed a phase II clinical trial to determine the safety and efficacy of dasatinib for patients with higher-risk myelodysplastic syndromes, chronic myelomonocytic leukemia, or acute myeloid leukemia resulting from MDS and have failed treatment with azanucleosides.

Combination of HUCBCs and Simvastatin offers promising therapy for stroke: Study

Researchers at the Henry Ford Health System (Detroit, MI) and colleagues at Saneron CCEL Therapeutics, Inc. of Tampa, Florida, have found that when human umbilical cord blood cells were transplanted into test rats modeled with stroke, the addition of Simvastatin to the HUCBCs significantly increased the therapeutic benefit of the HUCBCs.

Importance of choosing correct catheter placement in hospitalized children

Location, location, location. A new Johns Hopkins Children's Center study shows the real-estate mantra also holds true when it comes to choosing correct catheter placement in children.

University of Nottingham to study use of tranexamic acid in people with intracerebral haemorrhage

Scientists in Nottingham are leading an international study to investigate the effectiveness of a new treatment on a devastating type of stroke.

Researchers find no overall recovery benefit to patients treated with clot-removal devices

When someone has a stroke, time equals brain. The longer a stroke is left untreated, the more brain tissue is lost. Since the only proven treatment - a clot-busting drug - works in less than half of patients, stroke physicians had high hopes for a mechanical device that could travel through the blocked blood vessel to retrieve or break up the clot, restoring blood flow to the brain.

UCLA team uses brain aneurysm treatment technique to treat irregular heart rhythms

For the first time, a UCLA team has used a technique normally employed in treating brain aneurysms to treat severe, life-threatening irregular heart rhythms in two patients.

Researchers develop new plug-and-play method to assemble complex cell microenvironments

Researchers at Columbia Engineering have developed a new "plug-and-play" method to assemble complex cell microenvironments that is a scalable, highly precise way to fabricate tissues with any spatial organization or interest—such as those found in the heart or skeleton or vasculature.

Transfusion of older blood adversely affects patients undergoing cardiac surgery or critical care

Transfusion of donated blood more than three weeks old results in impaired blood vessel function, a new study of hospital patients shows.

Abbott announces data from MitraClip system study on mitral regurgitation

Abbott today announced data from the EVEREST II (Endovascular Valve Edge-to-Edge REpair STudy) High Surgical Risk cohort evaluating the company's first-in-class catheter-based MitraClip System for the treatment of mitral regurgitation (MR).

Study shows reduction of brain capillaries in mice immunized with amyloid beta

University of British Columbia researchers have successfully normalized the production of blood vessels in the brain of mice with Alzheimer's disease (AD) by immunizing them with amyloid beta, a protein widely associated with the disease.

High HDL levels block development of aneurysms in the aorta

New research provides early evidence that 'good' cholesterol may possess anti-aneurysm forming properties. In laboratory-based investigations, scientists found that increased levels of high-density lipoproteins (HDL), the so-called good cholesterol, blocked the development of aneurysms - dangerous 'ballooning' in the wall of a blood vessel - in the body's largest artery, the aorta.

Screening healthy adults could potentially prevent rare genetic disorders

Millions of people unknowingly carry rare gene mutations that put them at high risk of developing preventable diseases such as colorectal cancer, breast cancer, and several catastrophic blood vessel disorders.

tRNA synthetases play unexpected and critical role in cancer metastasis

Studied for decades for their essential role in making proteins within cells, several amino acids known as tRNA synthetases were recently found to have an unexpected - and critical - additional role in cancer metastasis in a study conducted collaboratively in the labs of Karen Lounsbury, Ph.D., University of Vermont professor of pharmacology, and Christopher Francklyn, Ph.D., UVM professor of biochemistry.

Investigators identify seven new genetic regions associated with AMD

An international group of investigators has identified seven new genetic regions associated with age-related macular degeneration (AMD), a common cause of blindness in older individuals. The findings, reported online March 3 in Nature Genetics, could point to new biological pathways and therapeutic targets for AMD.

NO triggers RGS4 degradation to coordinate angiogenesis and cardiomyocyte growth

Myocardial hypertrophy, a thickening of the heart muscle, is an adaptation that occurs with increased stress on the heart, such as high blood pressure. As the heart muscle expands, it also requires greater blood flow to maintain access to oxygen and nutrients, necessitating an expansion of the cardiac vasculature.

Scientists identify two populations of human cells that migrate to the intestine

Researchers at Wake Forest Baptist Medical Center and colleagues have identified a special population of adult stem cells in bone marrow that have the natural ability to migrate to the intestine and produce intestinal cells, suggesting their potential to restore healthy tissue in patients with inflammatory bowel disease (IBD).

Combined complement mutations affect individuals' risk of aHUS and prognosis

Certain gene mutations affect individuals' risk of developing a serious kidney condition, as well as their prognosis after being diagnosed with the disease, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).

Two new non-invasive technologies can improve early identification of tumor response to therapy

The research was published early in the January issue of the journal Technology in Cancer Research and Treatment. The article describes experiments using ultrasonic molecular imaging (USMI) and Dynamic Contrast Enhanced-Perfusion Imaging (DCE-PI) to measure response to therapy for pancreatic cancer.

Plasma plays a crucial part in determining how blood flows

Blood flows differently than water. Anyone who has ever cut themselves knows that blood flows viscously and rather erratically. The similarity between blood and ketchup is something not only filmmakers are aware of. Experts refer to these materials as "non-Newtonian fluids," of which ketchup and blood are prime examples.
