CDC to fund sickle cell disease surveillance

The Centers for Disease Control and Prevention (CDC) has announced a funding of $1.2 million to different states in order to collect data and information from people suffering from sickle cell disease. The program called the Sickle Cell Data Collection program or SCDC is at present functional in two states - California and Georgia. With the new funds coming in, nine states would be able to collect and send population based information on the health of persons living with sickle cell disease.

New study identifies potential enzyme target for diabetic retinopathy

A new study shows that diabetic retinopathy (DR), or retinal disease caused by the high blood glucose levels in diabetes mellitus, is due to the death of retinal cells because of the high levels of a pro-enzyme called lysyl oxidase propeptide (LOX-PP). This could help researchers develop specific treatments by targeting this molecule.

Researchers discover potential approach to treating diabetic retinopathy

Boston University researchers have identified an enzymatic precursor that is toxic to retinal cells and could be used in new treatments for diabetic retinopathy.

Virginia Tech scientist receives American Heart Association award to study stroke recovery

When someone has an ischemic stroke, doctors work swiftly to remove the arterial blockage and restore blood flow to the brain. But sometimes even once the blockage is removed, there's lasting - sometimes fatal - damage.

Supercooling helps preserve human transplant organs longer

Now a new supercooling technique for human organs promises to extend the period from the moment of removal to 1.5 days rather than just a few hours. This provides a useful window of time within which transplant teams and patients can hope to get a viable organ.

Researchers find synergistic connection between two deadly blood-clotting diseases

Two rare but potentially deadly blood-clotting diseases, namely thrombotic thrombocytopenic purpura, or TTP, and hemolytic uremic syndrome, or HUS, show similar pathologies -- a multitude of painful blockages in small blood vessels that cause varying degrees of organ injury throughout the body. However, the two disorders have distinct biological mechanisms.

Umea researchers' model reveals why memory deteriorates as the body ages

Researchers in Umeå, Sweden, have presented a model that explains why memory deteriorates as the body ages. With age, the brain receives an increased load from the heart's beating as the body's large arteries stiffen over the years, causing damage to the smallest blood vessels in the brain.

New MRI technique captures image of a brain thinking

An international team of researchers with partial support from the National Institute of Biomedical Imaging and Bioengineering developed a new MRI technique that can capture an image of a brain thinking by measuring changes in tissue stiffness.

Researchers explain why fascioliasis patients have increased risk for neurological diseases

Fascioliasis is a parasitic disease caused by two species that are present in the liver: Hepatic Fasciola, which is present worldwide, and Fasciola gigantica, which is in Asia and Africa.

Scientists suggest possible cell-based therapy for premature infants with rare lung condition

Researchers suggest a possible cell-based therapy to stimulate lung development in fragile premature infants who suffer from a rare condition called Bronchopulmonary Dysplasia, which in the most severe cases can lead to lifelong breathing problems and even death.

Researchers find a potential modulator in revascularization of pancreatic islets

The first cause of the loss of functionality in transplanted pancreatic islets is the low capacity to create new vessels to allow the arrival of nutrients in the cells.

Scientists pinpoint cause of fatal respiratory disorder that turns babies' lips and skin blue

Scientists used a gene editing method called CRISPR/Cas9 to generate mice that faithfully mimic a fatal respiratory disorder in newborn infants that turns their lips and skin blue. The new laboratory model allowed researchers to pinpoint the ailment's cause and develop a potential and desperately needed nanoparticle-based treatment.
