Blood stored for 29 days or more linked to infection

Blood stored for 29 days or more, nearly 2 weeks less than the current standard for blood storage, is associated with a higher infection rate in patients who received transfusions with the blood.

Discovery may help complications of diabetes - delayed gastric emptying or gastroparesis

Mayo Clinic researchers have found what may provide a solution to one of the more troubling complications of diabetes -- delayed gastric emptying or gastroparesis.

Researchers devise means to create blood by discovering earliest form of human blood stem cells

Johns Hopkins researchers have discovered the earliest form of human blood stem cells and deciphered the mechanism by which these embryonic stem cells replicate and grow. They also found a surprising biological marker that pinpoints these stem cells, which serve as the progenitors for red blood cells and lymphocytes.

Takeda and Affymax provide update for Hematide in chemotherapy-induced anemia

Takeda Pharmaceutical Company Limited and Affymax, Inc. today announced their agreement to suspend co-development of Hematide to treat chemotherapy-induced anemia and to focus all development efforts for Hematide on the treatment of chronic kidney disease related anemia.

Clinical-scale generation of functional red blood cells from human embryonic stem cells

Advanced Cell Technology, Inc. reported that it is feasible to differentiate and mature human embryonic stem cells (hESCs) into functional oxygen-carrying red blood cells (RBCs) under conditions suitable for scale-up.

Scientists discover platelets play an important early role in promoting cerebral malaria

Platelets - those tiny, unassuming cells that cause blood to clot and scabs to form when you cut yourself - play an important early role in promoting cerebral malaria, an often lethal complication that occurs mostly in children.

Gene doping in sport

Professor John Rasko, head of the Gene and Stem Cell Therapy Program at the Centenary Institute, University of Sydney, talks about gene doping and other methods of performance enhancement on the eve of the 2008 Beijing Olympics.

Findings may aid in bone marrow transplants, blood diseases

New research sheds light on the biological events by which stem cells in the bone marrow develop into the broad variety of cells that circulate in the blood. The findings may help improve the success of bone marrow transplants and develop better treatments for life-threatening blood diseases.

A new target for malaria drugs

The malaria parasite has waged a successful guerrilla war against the human immune system for eons, but a study in this week's Journal of Biological Chemistry has exposed one of the tricks malaria uses to hide from the immune proteins, which may aid in future drug development.

Commonly used diabetes monitoring test could identify millions of people with undiagnosed diabetes

A blood test currently used as the gold standard for monitoring people already under care for diabetes may have far wider use in identifying millions with undetected diabetes, a team led by a Johns Hopkins physician suggests.

Ultra-miniature bialy-shaped drug delivery particles

Ultra-miniature bialy-shaped particles - called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City - could soon be carrying medicinal compounds through patients' bloodstreams to tumors or atherosclerotic plaques.

New technique measures formation of clumps of proteins in protein-based pharmaceuticals

Scientists at the National Institute of Standards and Technology (NIST) have developed a technique to measure the formation of clumps of proteins in protein-based pharmaceuticals.

Genetic mechanisms at play in blood cells important in Parkinson’s disease

What does the genetics of blood cells have to do with brain cells related to Parkinson's disease? From an unusual collaboration of neurologists and a pharmacologist comes the surprising answer: Genetic mechanisms at play in blood cells also control a gene and protein that cause Parkinson's disease.

Gene variant increases HIV risk in Africans

A genetic variation which evolved to protect people of African descent against malaria has now been shown to increase their susceptibility to HIV infection by up to 40 per cent, according to new research. Conversely, the same variation also appears to prolong survival of those infected with HIV by approximately two years.

New understanding of fetal hemoglobin regulation in patients with sickle cell disease

Although sickle cell disease is a single-gene disorder, its symptoms are highly variable. In a study published online July 14 by the Proceedings of the National Academy of Sciences, scientists at Children's Hospital Boston and the Dana Farber Cancer Institute (DFCI), in collaboration with the Broad Institute of MIT and Harvard, report five gene variants that could potentially be helpful in predicting sickle cell disease severity, perhaps even leading to better treatment approaches in the future.

Scientists reveal key elements in Malaria parasite'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.

Heat waves when in hospital

Deaths due to high temperatures occur so quickly that patients do not have time to be admitted to hospital. This is why prevention campaigns are necessary to try and reduce the negative effects of the heat on health. This is pointed out in new research undertaken at the Hospital Universitario Gregorio Maranon, Madrid.

Scientists reveal potential new target for anti-malarial drugs

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 new target for anti-malarial drugs.

Nanocantilevers image nanoparticles in cells

Borrowing from a Nobel Prize-winning technique credited with starting the nanotechnology revolution, a team of researchers from Oak Ridge National Laboratory (ORNL) and Northwestern University's Nanomaterials for Cancer Diagnostics and Therapeutics has developed a method for imaging nanoparticles inside of cells.

New understanding of how malaria parasite survives in and totally changes red blood cells

A new study-done on a scale an order of magnitude greater than anything previously attempted in the field of malaria-has uncovered an arsenal of proteins produced by the malaria parasite that allows it to hijack and remodel human red blood cells, leaving the oxygen-carrying cells stiff and sticky.
