Study reveals how white blood cells get pushy to rapidly reach areas of infection

One of the mysteries of the living body is the movement of cells - not just in the blood, but through cellular and other barriers.

Tiny transport vesicles and shifts in metabolism can signal big changes in cancer tissues

Microscopic shifts in metabolism and increases in tiny transport vesicles out of tumor cells preface larger changes to the tumor environment and could prepare the way for cancerous cells to spread and metastasize, University of Illinois researchers report.

Joslin scientists suggest new approach to improve stroke therapy

The standard of care for treating strokes caused by blood clots involves the therapeutic infusion of tissue plasminogen activator (tPA), which can help to dissolve the clots and restore blood flow.

MRE technique detects tumor stiffness to enable non-invasive surgical planning

Important steps in planning tumor surgery include identifying borders between tumor and healthy tissue and assessing the tumor stiffness, e.g. hard and calcified or soft and pliant.

New project aims to improve efficiency of cytostatic drugs used in cancer treatment

Wilfried Weber, Professor of Synthetic Biology at the University of Freiburg, has received a grant of roughly €150,000 for his project "Hide and Seek with Cancer Drugs" in which he is working to improve the drugs used in cancer treatment

Scientists discover cause of tumour resistance to angiogenesis inhibitors

A new study conducted by MedUni Vienna in collaboration with scientists from Hungary and Sweden has now shown for the first time that the success of specialised drugs to inhibit blood supply to tumours - so-called angiogenesis inhibitors - is compromised by the fact that these drugs do not effectively penetrate the tumour tissue and so do not reach the smallest blood vessels in the tumour.

Researchers explore feasibility of carbon ions for treating cardiac arrhythmia

Approximately 350,000 patients in Germany suffer from various forms of cardiac arrhythmia. The condition can lead to permanent damage as a result of stroke, or it may cause sudden heart failure.

Landmark clinical trial testing new ablation procedure to treat life-threatening heart rhythm disorder

Loyola Medicine is the only center in the Midwest enrolling patients in a landmark clinical trial of a new procedure to treat a life-threatening heart rhythm disorder called ventricular tachycardia.

Novel noninvasive method precisely tweaks brain activity in rats using ultrasound pulses

Biomedical engineers at Johns Hopkins report they have worked out a noninvasive way to release and deliver concentrated amounts of a drug to the brain of rats in a temporary, localized manner using ultrasound.

New biomarker helps better predict survival after surgical removal of colorectal metastases

Liver metastases are formed from cancer cells that have originated in other organs and migrated to the liver via the bloodstream. Colorectal cancer (cancer of the colon/rectum) can be successfully treated by surgical resection of the metastases in combination with chemotherapy.

Novel approach for imaging immune cell movements identifies initial steps in inflammatory arthritis

Using a novel approach for imaging the movement of immune cells in living animals, researchers from the Massachusetts General Hospital Center for Immunology and Inflammatory Diseases have identified what appear to be the initial steps leading to joint inflammation in a model of inflammatory arthritis.

Researchers develop new high-tech medical device to make brain surgery safer

A new high-tech medical device to make brain surgery safer has been developed by researchers at the University of Adelaide.

Advances in imaging technology help diagnose more trauma patients with blunt cerebrovascular injuries

Advances in diagnostic imaging technology have meant that more trauma patients are being diagnosed with blunt cerebrovascular injuries, and as a result, stroke and related death rates in these patients have declined significantly over the past 30 years.

Salk scientists show how microenvironment signals encourage growth of pancreatic tumors

Just as an invasive weed might need nutrient-rich soil and water to grow, many cancers rely on the right surroundings in the body to thrive.

RIT research explores impact of shear stress on cells moving through blood vessels

How do cells and protein molecules respond to stress as they travel through blood vessels? Could resulting changes to these biological components impact how diseases are spread?

More than half of AF patients who undergo catheter ablation become asymptomatic, study reports

More than half of patients with atrial fibrillation (AF) become asymptomatic after catheter ablation, reports the largest study of the procedure published today in European Heart Journal.

Endogenous peptide inhibits atherosclerosis by reducing cholesterol levels

Cells of the innate immune system that play an important role in development of atherosclerosis contain a protein that reduces levels of cholesterol in mice - and thus helps to inhibit or mitigate the disease.

New techniques and treatments show promise for eliminating retinopathy of prematurity

A mini-symposium published in the Journal of the American Association for Pediatric Ophthalmology and Strabismus provides important insights into new techniques and treatments that show promise for eliminating retinopathy of prematurity (ROP) throughout the world.

Epigenetic changes drive successful metastases of pancreatic cancer cells

A multicenter team of researchers reports that a full genomic analysis of tumor samples from a small number of people who died of pancreatic cancer suggests that chemical changes to DNA that do not affect the DNA sequence itself yet control how it operates confer survival advantages on subsets of pancreatic cancer cells.

NTNU researchers testing use of new removable stent in the lungs

A knitted rag sock inspired this professor and MD to develop a stent that can easily be removed after it has done its job.
