Cellular extensions with a large effect
- Details
- Category: Research
Tiny extensions on cells, cilia, play an important role in insulin release, according to a new study, which is published in Nature Communications. The researchers report that the cilia of beta cells in the pancreas are covered with insulin receptors and that changed ciliary function can be associated with the development of type 2 diabetes.
NSAIDs prevent colon cancer by inducing death of intestinal stem cells that have mutation
- Details
- Category: Research
Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) protect against the development of colorectal cancer by inducing cell suicide pathways in intestinal stem cells that carry a certain mutated and dysfunctional gene, according to a new study led by researchers at the University of Pittsburgh Cancer Institute (UPCI) and the School of Medicine.
Researchers aim to simplify life saving drug
- Details
- Category: Research
Heparin, the life saving blood thinner used in major surgeries and treatment of heart diseases, is a complicated drug but a research team from the University of British Columbia has set out to make its use a lot safer by developing a universal antidote. Heparin's blood thinning action often requires an antidote to reverse its effect before serious bleeding issues arise especially in the case of major surgical procedures.
Scientists capture picture of 'MicroRNA' in action
- Details
- Category: Research
Biologists at The Scripps Research Institute (TSRI) have described the atomic-level workings of "microRNA" molecules, which control the expression of genes in all animals and plants. The findings add greatly to the understanding of a fundamental system of regulation in biology, and should accelerate the development of therapies that harness its power.
Scientists find genetic variants influence a person's response to statins
- Details
- Category: Research
A large analysis of over 40,000 individuals on statin treatment has identified two new genetic variants which influence how 'bad' cholesterol levels respond to statin therapy. Statins are widely prescribed to patients and have been shown to lower bad cholesterol levels by up to 55%, making them a highly effective method of reducing risk of heart disease.
Adverse drug reactions in children following use of asthma medications
- Details
- Category: Research
In a new study based on EU adverse drug reaction reports, researchers at the University of Copenhagen and the University of Southern Denmark now document that children's use of asthma medications may result in serious adverse drug reactions. The risk of adverse drug reactions is not fully documented in the pre-marketing clinical trials.
Clinical trial could change standard treatment for stroke
- Details
- Category: Research
A large international clinical trial has shed new light on the effectiveness of current hospital protocols for managing blood pressure in stroke patients. The two-part ENOS trial (Efficacy of Nitric Oxide in Stroke,) was carried out at The University of Nottingham in collaboration with 23 countries to try to solve two major conundrums faced by doctors when treating people who have suffered a stroke
