A bacteria which infects people with cystic fibrosis could help combat other antibiotic-resistant microbes, according to a team from Cardiff and Warwick Universities.
Continuous use of existing antibiotics means that resistant bacteria are now causing major health problems all over the world. New antibiotics are urgently needed to combat the emergence of multidrug-resistant bacteria such as the MRSA superbug.
Smart windows which, thanks to a nanocoating, adjust their level of transparency to suit the sun's brightness, so helping to save energy; novel diagnostic methods and tailor-made nano-medicines to treat HIV and arteriosclerosis;. nanofibers which, on the one hand, can be used to make very efficient dust filters and on the other, thanks to integrated pheromones, protect vineyards from insect attack; new nanostructured materials for making more efficient batteries;.
MAYWOOD, Ill. – Studies show that minorities who suffer strokes are less knowledgeable than whites about risk factors and are slower to receive care when every minute counts, according to a scientific statement from the American Heart Association/American Stroke Association.
Loyola University Health System stroke specialist Dr. José Biller is a member of the panel of experts who wrote the statement, which was published online May 26 in Stroke: Journal of the American Heart Association.
The study, commissioned by the National Institute for Health and Clinical Excellence (NICE) and undertaken by the UK Centre for Tobacco Control Studies (UKCTCS), reviewed published studies from between 1990 and 2007 to establish success rates for the NHS smoking cessation services. It found that older smokers are more likely than young smokers to successfully quit, some men appear to be more successful at quitting than women despite the fact that more women attend the smoking cessation services, and more disadvantaged groups face greater challenges when giving up smoking.
Only three percent (n=181) of patients in the study cohort receiving anti-tumour necrosis factor agents (anti-TNFs) for treatment of their arthritis developed a first cancer within nine years and overall risk was not dependent on the type of arthritis.
Scientists from the University of Warwick have discovered why a newly found form of cholesterol seems to be 'ultra-bad', leading to increased risk of heart disease. The discovery could lead to new treatments to prevent heart disease particularly in people with type 2 diabetes and the elderly.
PHILADELPHIA— Researchers at the Kimmel Cancer Center at Jefferson have shed new light on the longstanding conundrum about what makes a tumor grow—and how to make it stop. Interestingly, cancer cells accelerate the aging of nearby connective tissue cells to cause inflammation, which ultimately provides "fuel" for the tumor to grow and even metastasize.
Thirty-eight million years ago, tropical jungles thrived in what are now the cornfields of the American Midwest and furry marsupials wandered temperate forests in what is now the frozen Antarctic.
The temperature differences of that era, known as the late Eocene, between the equator and Antarctica were half what they are today.
A debate has been ongoing in the scientific community about what changes in our global climate system led to such a major shift from the more tropical, greenhouse climate of the Eocene to modern and much cooler climates.
TORONTO, Ont., May 26, 2011—Folic acid supplements given to pregnant and breast-feeding rats reduced the rate of colon cancer in their offspring by 64 per cent, a new study has found.
The research, led by Dr. Young-in Kim, a gastroenterologist at St. Michael's Hospital, adds to the growing but sometimes contradictory evidence that folic acid supplementation during pregnancy and lactation can increase or decrease the development or progression of some pediatric malignancies and common cancers in their offspring in adulthood.
Athens, Ga. – A technical comment published in the current (May 27) edition of the journal Science casts doubt on a widely publicized study that concluded that a bacterial bloom in the Gulf of Mexico consumed the methane discharged from the Deepwater Horizon well.
The debate has implications for the Gulf of Mexico ecosystem as well as for predictions of the effect of global warming, said marine scientist and lead author Samantha Joye, University of Georgia Athletic Association Professor in Arts and Sciences.
Troy, N.Y. – Thirty-eight million years ago, tropical jungles thrived in what are now the cornfields of the American Midwest and furry marsupials wandered temperate forests in what is now the frozen Antarctic. The temperature differences of that era, known as the late Eocene, between the equator and Antarctica were only half of what they are today. A debate has long been raging in the scientific community on what changes in our global climate system led to such a major shift from the more tropical, greenhouse climate of the Eocene to the modern and much cooler climates of today.
HOUSTON – (May 27, 2011) – Cells, like ordinary households, produce "garbage" – debris and dysfunctional elements – that need disposal. When the mechanism for taking out this garbage fails, rare genetic diseases called lysosomal storage disorders (including Tay-Sachs, Batten and Fabry disease) can disable and even kill the children they affect. In adults, such failure leads to neurodegenerative diseases that occur later in life, such as Alzheimer's and Parkinson's diseases.
TEMPE, Ariz.- A Biodesign Institute at Arizona State University research team has developed a process that removes a key obstacle to producing low-cost, renewable biofuels from bacteria. The team has reprogrammed photosynthetic microbes to secrete high-energy fats, making byproduct recovery and conversion to biofuels easier and potentially more commercially viable.
EAST LANSING, Mich. — While recent studies have shown long-term exposure to estrogen can be a danger to women – overturning physicians' long-held beliefs that the hormone was good for their patients' hearts – the process by which estrogen induces high blood pressure was unclear.
In April 2009, researchers at UCLA announced they had discovered a link between Parkinson's disease and two chemicals commonly sprayed on crops to fight pests.
That epidemiological study didn't examine farmers who constantly work with pesticides but people who simply lived near where farm fields were sprayed with the fungicide maneb and the herbicide paraquat. It found that the risk for Parkinson's disease for these people increased by 75 percent.
