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.

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.

Study investigates how cancer cells 'hijack' platelets

A new research study has investigated how cancer cells 'hijack' blood cells known as platelets, enabling cancer to spread around the body and promoting the growth of new tumours, it was reported today at the annual Royal College of Surgeons in Ireland (RCSI) Research Day.

Study shows how fish oils help lower blood pressure via vasodilation at ion channels

Omega-3 fatty acids found in oily fish may have diverse health-promoting effects, potentially protecting the immune, nervous, and cardiovascular systems.

Chemotherapy-free stem cell transplant shows promise for sickle cell disease

Two brothers have been cured of their sickle cell disease at the University of Illinois Hospital & Health Sciences System using a relatively uncommon type of stem cell transplant that is performed without chemotherapy.

Endocrine Society issues position statement on estradiol measurement

In a Position Statement unveiled today, The Endocrine Society advocates that all methods for measuring estrogens, which play a crucial role in human biology, be made traceable to a common standard.

Study shows how high shear stress could cause VWF to change shape and form blood clots

New research from Rice University, Baylor College of Medicine (BCM) and the Puget Sound Blood Center (PSBC) has revealed how stresses of flow in the small blood vessels of the heart and brain could cause a common protein to change shape and form dangerous blood clots.

Scientists decode the antihypertensive impact of omega-3 fatty acids

Scientists of Friedrich Schiller University Jena and Jena University Hospital decode the antihypertensive impact of omega-3 fatty acids. In two newly published articles for the well-known science magazine 'Proceedings of the National Academy of Sciences, USA' they describe how they analyzed the impact of omega-3 fatty acids on a systemic level and they also described the underlying molecular mechanisms for the first time.

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.

Children with low-risk retinoblastoma do not need postoperative chemotherapy

New results from a prospective clinical trial conducted in France show that children with low-risk retinoblastoma do not need postoperative (adjuvant) chemotherapy to prevent disease recurrence or metastasis; the results also suggest that certain patients with intermediate-risk disease can receive less aggressive adjuvant treatment, or perhaps forego it altogether. Avoiding chemotherapy spares patients from treatment side effects and long-term health risks, such as cardiovascular disease and development of a second cancer.

Overall risk of infection associated with most neuroangiographic procedures is very low

Patients undergoing cerebral angiography and neurointerventional procedures on the brain are at very low risk of infection-even without preventive antibiotics, reports a study in the March issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Study examines how bacteria clog medical devices

A new study has exam-ined how bac-te-ria clog med-ical devices, and the result isn't pretty. The microbes join to cre-ate slimy rib-bons that tan-gle and trap other pass-ing bac-te-ria, cre-at-ing a full block-age in a star-tlingly short period of time.

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.

Anti-LG3 associated with high rate of organ rejection during transplantation

A team led by Dr. Marie-Jos-e H-bert from the University of Montreal Hospital* Research Centre (CRCHUM) has discovered a new cause of organ rejection in some kidney transplant patients. Her team has identified a new class of antibodies - anti-LG3 - which when activated lead to severe rejection episodes associated with a high rate of organ loss.

Early lymphoid progenitors thrive in an osteoblastic niche: Study

The Children's Medical Center Research Institute at UT Southwestern has deepened the understanding of the environment within bone marrow that nurtures stem cells, this time identifying the biological setting for specialized blood-forming cells that produce the infection-fighting white blood cells known as T cells and B cells.

WUSTL to develop 3-D computer models of brain biomechanics to better understand TBI

Washington University in St. Louis engineering researchers have received a five-year, $2.25 million grant to better understand traumatic brain injuries in efforts to improve methods for prevention and treatment.

Loyola offers tips to help stay healthy during shoveling season

A mild winter means many are out of practice in the fine art of snow shoveling. But bending and lifting the wrong way can lead to a trip to the emergency department.

HIF-1α protein can work directly to stop new cells from forming

A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, Johns Hopkins researchers report. Their discovery has wide-ranging implications, they say, given the importance of this copying - known as DNA replication - and new cell growth to many of the body's functions and in such diseases as cancer.
