- Capsaicin can act as co-carcinogen, study finds; Chili pepper component linked to skin cancer
New research links capsaicin, a component of chili peppers, to skin cancer. While the molecular mechanisms of the cancer-promoting effects of capsaicin are not clear and remain controversial, the new research has shown a definite connection to formation of skin cancer through various laboratory studies.
- Cranberry juice shows promise blocking Staph infections
Expanding their scope of study on the mechanisms of bacterial infection, researchers have reported the surprise finding from a small clinical study that cranberry juice cocktail blocked a strain of Staphylococcus aureus from beginning the process of infection.
- Cancer-causing gene crucial in stem cell development, study finds
A research team has shown for the first time that a gene called Myc, which is traditionally thought of as a cancer-causing gene, may be far more important in the development and persistence of stem cells than was known before.
- Computer technique could help partially sighted 'see' better
Thousands of people who are partially sighted following stroke or brain injury could gain greater independence from a simple, cheap and accessible training course which could eventually be delivered from their mobile phones or hand-held games consoles, according to a new study.
- Children who eat vended snack foods face chronic health problems, poor diet, study finds
School children who consume foods purchased in vending machines are more likely to develop poor diet quality -- and that may be associated with being overweight, obese or at risk for chronic health problems such as diabetes and coronary artery disease, according to new research.
- Increased risk for lupus in men with certain form of immune receptor
Humans -- males in particular -- with a variant form of the immune receptor gene "Toll Like Receptor 7" are at increased risk of developing the autoimmune disease lupus. This finding offers renewed hope for developing more targeted treatments.
- Social networks influence health behaviors
Individuals are more likely to acquire new health practices while living in networks with dense clusters of connections -- that is, when in close contact with people they already know well.
- Cigarette smoke may contribute to lung inflammation through a new chemical pathway
Cigarette smoke shuts off a key enzyme in airways that regulates the body's response to inflammation, according to new findings. Researchers say smoke inhibits the enzyme, called Leukotriene A4 Hydrolase (LTA4H), causing it to fail in its job of shutting down white blood cells following a successful response to inflammation.
- Serendipity contributes to MRSA susceptibility findings
Researchers have found two genes in mice which might help identify why some people are more susceptible than others to potentially deadly staph infections.
- Problem of fake medicines in developing countries could be solved, experts say
Counterfeiting of drugs is a huge industry. In Africa the situation is extremely serious. Half of the malaria medication sold there could be ineffective or even harmful. There is currently no good way to identify counterfeit drugs. However, researchers in Sweden and the UK have now developed a technique that could resolve the situation.
- Molecules involved in 'touch' identified: Could lead to new treatments for pain, deafness and cardiac function
Scientists have identified two proteins with potential to be important targets for research into a wide range of health problems, including pain, deafness, and cardiac and kidney dysfunction.
- Value of oxygen therapy in end-of-life care challenged in new study
Millions of patients with advanced disease in palliative care settings receive oxygen therapy to help them breathe more easily. But a new study says roughly half of them don't benefit from the intervention, and among those who do benefit, it doesn't make a bit of difference whether they get pure oxygen or just plain old room air -- both offer equal benefit.
- How do organisms make dietary choices?
When given a choice, organisms will choose a diet that maintains a nutritional balance in tune with their needs. That choice, studied in fruit flies for the first time, is regulated by activity in a molecular pathway involved in aging, cancer and diabetes. Humans share the same molecular pathway. The study, the first to be done in a genetically tractable lab animal, could lead to treatments that would "reboot" metabolic pathways in individuals who are obese or suffer from diabetes.
- New warning signs may predict kidney transplant failure
Kidney transplants that show a combination of fibrosis (scarring) and inflammation after one year are at higher risk of long-term transplant failure, according to a new study.
