Hot nanoparticles for cancer treatments

Hot nanoparticles for cancer treatments

Nanoparticles have a great deal of potential in medicine: for diagnostics, as a vehicle for active substances or a tool to kill off tumors using heat. Continue reading

Microfluidic device with artificial arteries measures drugs’ influence on blood clotting

Microfluidic device with artificial arteries measures drugs’ influence on blood clotting

A new microfluidic method for evaluating drugs commonly used for preventing heart attacks has found that while aspirin can prevent dangerous blood clots in some at-risk patients, it may not be effective in all patients with narrowed arteries. The study, which involved 14 human subjects, used a device that simulated blood flowing through narrowed coronary arteries to assess effects of anti-clotting drugs. Continue reading

Southeast England most at risk of rising deaths due to climate change

Southeast England most at risk of rising deaths due to climate change

Warmer summers brought on by climate change will cause more deaths in London and southeast England than the rest of the country, scientists predict. Researchers at Imperial College London looked at temperature records and mortality figures for 2001 to 2010 to find out which districts in England and Wales experience the biggest effects from warm temperatures. In the most vulnerable districts, in London and the southeast, the odds of dying from cardiovascular or respiratory causes increased by over 10 per cent for every 1C rise in temperature.

Leukaemia caused by chromosome catastrophe

Leukaemia caused by chromosome catastrophe

Researchers have found that people born with a rare abnormality of their chromosomes have a 2,700-fold increased risk of a rare childhood leukemia. In this abnormality, two specific chromosomes are fused together but become prone to catastrophic shattering. Continue reading

New method can diagnose feared pancreatic cancer

New method can diagnose feared pancreatic cancer

Pancreatic cancer is often detected at a late stage, which results in poor prognosis and limited treatment options. Researchers at The University od Gothenburg, Sweden, have now developed a method which identifies the cancer’s visible precursors with 97% certainty. Continue reading

Surprising new way to kill cancer cells

Surprising new way to kill cancer cells

Northwestern Medicine scientists have demonstrated that cancer cells — and not normal cells — can be killed by eliminating either the FAS receptor, also known as CD95, or its binding component, CD95 ligand. “The discovery seems counterintuitive because CD95 has previously been defined as a tumor suppressor,” said lead investigator Marcus Peter, professor in medicine-hematology/Oncology at Northwestern University Feinberg School of Medicine. “But when we removed it from cancer cells, rather than proliferate, they died.” The findings were published March 20 in Cell Reports Continue reading

Preterm children at increased risk of having math problems

Preterm children at increased risk of having math problems

Researchers have found that preterm children are at an increased risk of having general cognitive and mathematic problems. The new study by the University of Warwick and Ruhr-University Bochum, published in the Journal of Pediatrics , sought to understand the relationship between preterm birth and dyscalculia. Dyscalculia, a learning disorder which involves frequent problems with everyday arithmetic tasks, is diagnosed when children do worse in maths than would be expected based on their general intelligence Continue reading
