Stroke risk for sickle cell children with early complications

Children with sickle cell disease who experienced major complications such as pain and lung disease early in life are at no greater risk for stroke or death during later childhood, new research from UT Southwestern Medical Center shows.

Giving birth to a child naturally increases risk of hemorrhage in newborns

The first researchers to use magnetic resonance imaging (MRI) to study the brains of a large group of babies soon after birth found a small amount of bleeding in and around the brains of one in four babies who were delivered vaginally.

Stroke treatment helps victims recover brain function

A small but significant study in the U.S. has found that a treatment which was designed to clear blocked carotid arteries and prevent stroke has also improved brain function.

Dll4 signalling through Notchi regulates formation of tip cells during angiogenesis

All tissues, sick and healthy alike, need a blood supply to survive and grow. The key to many medical problems, like preventing tumour development, is therefore to obstruct the spread of the blood vessels. Research scientists at Karolinska Institutet have now discovered a heretofore unknown mechanism for how the body links together its blood vessels.

Nanocarrier stimuli-activated gene delivery

One approach to developing tumor-specific drug delivery agents is to create nanomaterials that release a therapeutic payload only after reaching their intended target.

New drug to treat kidney failure during septic shock

Research from Melbourne's Howard Florey Institute and the Austin Hospital has resulted in a drug to treat kidney failure during septic shock, which will be trialled at the Austin Hospital from mid-2007.

FoxOs shown to be potential new targets for cancer drugs

In an elegant, multiple-gene knockout experiment, a team of Boston scientists has discovered that a trio of molecules, called FoxOs, are fundamentally critical in preventing some cancers, maintaining blood vessel stability, and in keeping blood-forming stem cells healthy.

Targeting of cancer cells with ferrimagnetic ferritin cage nanoparticles

Researchers at Montana State University have used an engineered form of ferritin, a cage-like iron storage protein, to both synthesize and deliver iron oxide nanoparticles to tumors.

Biomimetic amplification of nanoparticle homing to tumors

A collaborative, multidisciplinary team of researchers has created nanoparticles that act much like a developing clot to target tumors.

Milk eliminates cardiovascular health benefits of tea

Research published on-line in European Heart Journal has found that the protective effect that tea has on the cardiovascular system is totally wiped out by adding milk.

Milk wipes out heart benefits offered by tea

Research published online in the European Heart Journal has found that the protective effect that tea has on the cardiovascular system is totally wiped out by adding milk.

New alarm system protects nerves during surgery

An alarm tone warns the surgeon that the position of his scalpel is dangerously close to the nerve leading to the patient's vocal cords - the beep tone signals excessive pressure on the nerve.

In vivo tumor targeting and radionuclide imaging with self-assembled nanoparticles

In an attempt to determine what factors make one nanoparticle better than another at targeting tumors, a team of investigators in Korea have conducted a systematic tumor-targeting study of a variety of self-assembling nanoparticles.

Vascular targeted nanoparticles for imaging and treatment of brain tumors

Combining two promising approaches to diagnosing and treating cancer, a multidisciplinary research team at the University of Michigan has created a targeted multifunctional polymer nanoparticle that successfully images and kills brain tumors in laboratory animals.

Why COX-2 inhibitors such as Vioxx can cause heart attacks and strokes

COX-2 inhibitors are primarily used to treat pain in conditions such as arthritis. They work by blocking the COX-2 enzyme, which is expressed at sites of inflammation and underlies the production of hormones called prostaglandins which swell the joints and cause the feeling of pain.

Old red wines best for a healthy heart

According to British scientists when it comes to the health benefits of red wine, the good old French or Italian reds are by far the best option.

Whoever said people were much the same was wrong!

An international research team have come up with a new genetic map which could demand a fundamental shift in how we think genes work.

Watching a tumor cell migrate

Using a microfluidics device designed to reproduce the physical microenvironment of small blood vessels and the spaces between cells, researchers at the National University of Singapore have imaged single tumor cells deforming as they migrate through the device.

Cause of exercise intolerance in heart failure patients

A new study shows that blood flow to the legs is relatively normal in people with diastolic heart failure, suggesting other potential causes of their inability to do everyday activities, according to researchers at Wake Forest University Baptist Medical Center.
