Drawing a crowd: How progenitor cells are recruited to tumor blood vessels from the bone marrow
Cells within the bone marrow (progenitor cells) that express a protein called CD34 have been shown to leave the marrow and travel to sites of tissue injury to mediate repair.   view more (2006-02-24)

High levels of uric acid may be associated with high blood pressure
Reducing levels of uric acid in blood lowered blood pressure to normal in most teens in a study designed to investigate a possible link between blood pressure and the chemical, a waste product of the body's normal metabolism.   view more (2008-08-27)

A Delicate Blood Balancing Act
As you sit and read this article, between four and six litres of blood are flowing around your body. Have you ever thought about what is involved when this flow is stopped somewhere and a blood clot forms? Vascular haemostasis is the delicate balancing act between keeping blood in its fluid state... view more (2003-03-13)

New bone marrow model could help people with sickle cell disease
A new model showing how sickle cell blood cells operate within bone marrow is presented at a conference in Austria today. Researchers at Imperial College London, who developed the model, hope that it will eventually be used by clinicians to advance more effective treatments for sickle cell disease.... view more (2005-02-18)

Dangerous interaction between cholesterol-lowering drug and antidiabetic drug
Researchers from the University of Helsinki, Finland have found that the cholesterol-lowering agent gemfibrozil (marketed as Lopid and generics) greatly increases the concentrations of repaglinide (Novonorm, Prandin) in blood. This interaction considerably enhances and prolongs the blood... view more (2003-04-16)

Kenyan Study Could Help Other African Countries Improve Hiv Blood-transfusion Strategies (p 657)
A 1994 study which highlighted the problem of HIV-1 transmission from blood-transfusion programmes in Kenya-and resulted in positive government action-could help other African countries develop safer blood-transfusion strategies. Little support for blood-safety programmes has been provided to... view more (2001-08-22)

Gene therapy to lower blood pressure just enough
A newly developed virus that introduces a blood pressure-lowering gene into cells and enables that gene to maintain blood pressure at healthy levels for four months promises to take gene therapy for the disorder a step closer to reality.   view more (2005-09-28)

High blood pressure may be due to excess weight in half of overweight adults
As many as 50 percent of overweight men and women with high blood pressure may have hypertension as a result of being overweight, researchers reported today at the American Heart Association's 61st Annual Fall Conference of the Council for High Blood Pressure Research.   view more (2007-10-01)

Fighting cancer with aspirin?
When looking for new weapons in the war on cancer, scientists should turn to their medicine cabinets for an age-old remedy-aspirin. According to scientists at the University of Newcastle (UK), aspirin has cancer-fighting effects that extend beyond already understood Cox inhibitors.   view more (2006-10-02)

Vampire bats recognise their prey's breathing
Vampire bats, the only mammals to feed exclusively on blood, including human blood, recognize their prey by the sound of its breathing.   view more (2006-06-19)

Building a hand-held lab-on-a-chip to simplify blood tests
A cell phone-sized blood-count machine requiring less blood than a mosquito bite will make blood tests easier for many patients, from neonatal units to astronauts in space.   view more (2006-04-13)

UQ researchers identify thousands with curable high blood pressure
A team of researchers led by Professor Richard Gordon and Associate Professor Michael Stowasser has found primary aldosteronism (PAL) - a type of high blood pressure that can be cured by surgery - to be ten times more common than was previously suspected.   view more (2007-04-19)

New role for Natural Killers!
Scientists at the University of York have discovered a new role for a population of white blood cells, which may lead to improved treatments for chronic infections and cancer.   view more (2008-08-28)

How blood flow dictates gene expression
Researchers at the University of Pennsylvania School of Medicine have pinpointed a key regulatory protein that translates blood flow into gene expression.   view more (2006-12-21)

U of MN researchers turn cord blood into lung cells
Researchers at the University of Minnesota have, for the first time, coaxed umbilical cord blood stem cells to differentiate into a type of lung cell.   view more (2006-11-02)

How to grow muscle cells in a dish
Smooth muscle cells (SMCs) are a crucial cellular component of many parts of the body, including blood vessels, the intestines, and the lungs.   view more (2006-11-10)

Ultrasound waves aid in rapid treatment of DVT
The use of ultrasound waves for deep vein thrombosis (DVT) may help dissolve blood clots in less time than using clot-busting drugs alone, according to researchers at Emory University.   view more (2008-11-24)

Angiogenesis : Blocking tumor growth and treating infarction - a new target
Our tissues are able to form new blood vessels throughout life. This mechanism, which is called angiogenesis, is essential notably in the case of myocardial infarction, stroke and limb ischemia. The very same mechanism, however, keeps tumors supplied with nutrients and oxygen thus enabling them to... view more (2005-04-25)

Clinical study results using Aldagen's product to isolate cord blood stem cells presented at ASH
Aldagen, Inc. today announced the presentation of data from a clinical trial using its ALDESORT® product to isolate stem cells from cord blood. The trial is being conducted by Joanne Kurtzberg, MD, the Duke University physician who pioneered the use of umbilical cord blood as a treatment for... view more (2006-12-12)

Identifying and disrupting key elements of malaria's 'sticky sack' adhesion strategy
Malaria is one of the most devastating diseases afflicting humanity. It infects and debilitates about 600 million people and kills up to three million people every year, mainly in the wet tropical regions of the world. Children and pregnant women are at particularly high risk.   view more (2008-07-11)

An Overly-Tight Neck Tie Increases Risk Of Glaucoma
Wearing your necktie tight might look smart, but it could increase the risk of developing the serious eye disease glaucoma, reveals a study in the British Journal of Ophthalmology. The researchers tested the internal blood pressure (intraocular pressure) of one eye in each of 20 healthy men and 20... view more (2003-07-25)

Cocoa intake linked to lower blood pressure, reduced risk of death
A study of elderly Dutch men indicates that eating or drinking cocoa is associated with lower blood pressure and a reduced risk of death.   view more (2006-02-28)

'Lite' low tar cigarettes impair blood flow as much as regular cigarettes
Low tar "lite" cigarettes impair blood flow through the heart as severely as regular cigarettes, reveals a small study published ahead of print in the journal Heart.   view more (2007-05-15)

Discovery of key malaria proteins could mean sticky end for parasite
Scientists funded by the Wellcome Trust have identified a key mechanism that enables malaria-infected red blood cells to stick to the walls of blood vessels and avoid being destroyed by the body's immune system. The research, published today in the journal Cell, highlights an important potential... view more (2008-07-10)

Gene-expression profiling of the effects of liver toxins
Gene-expression data from liver tissue or whole blood can be used to classify histopathologic differences in the effects of hepatotoxins. It is hoped that these findings, published in BioMed Central's open access journal, Genome Biology, will lead to a more precise way of defining the potential... view more (2008-06-20)
