Poor tomatoes. They've overtaken spinach as the organic food we most worry about
and they've been in the middle of the genetically modified foods debate
Yet tomatoes have their proponents as well, like HyunSoon Kim from the Korea Research Institute of Bioscience and Biotechnology (KRIBB) and colleagues from Digital Biotech Inc. and the Department of Biological Science at Wonkwang University. They say this humble fruit could be a suitable carrier for an oral vaccine against Alzheimer’s disease.
Vaginal microbicides currently in clinical trials may be the only weapon that will protect women against infection from HIV but they may actually be of more benefit to men than women, according to a new UCLA AIDS Institute study.
Microbicides are compounds that can be applied inside the vagina to protect against HIV and other sexually transmitted diseases. Pharmaceutical companies are currently conducting trials of second-generation microbicides that are based on antiretroviral, or ARV, drugs.
The study, which used novel mathematical models to simulate clinical trials and population-level transmission of HIV, appears July 7 in the online issue of Proceedings of the National Academy of Sciences.
Tabebuia impetiginosa, commonly known as Pink Ipê, is a deciduous tree, native to Central and South America, and is related to magnolias.
With obesity levels rising (and people apparently unwilling to eat moderately) scientists have been searching for ways to mitigate obesity and the related conditions it brings, such as diabetes and heart disease.
Scientists from Germany have recently discovered that extracts of Tabebuia impetiginosa, a traditional herbal remedy, can act to delay the absorption of dietary fat in animal models. They believe that the extract could be incorporated into a food supplement which may not only reduce obesity, but also lessen the risk of development of type 2 diabetes and coronary heart disease.
Six of every 100 patients who die in hospital do so as a consequence of an adverse drug reaction or, in other words, a fatal reaction to medicines, according to research carried out at the Department of Medicine of the University of Granada, in collaboration with the Clinical Hospital San Cecilio of Granada, by Alfredo José Pardo Cabello and directed by Professors Emilio Puche Cañas (Department of Pharmacology) and Francisco Javier Gómez Jiménez (Department of Medicine).
A adverse drug reaction to medicines (ADR) has been defined as any harmful and unwanted effect of a drug, at doses used for prophylaxis, diagnose or treatment. Their repercussion is usually minimal, but sometimes, they can be serious and they can even endanger the patient’s life.
The French like their artichokes fried, the Italians like them on pizza, in Spain they are used in frittata and the best artichokes are supposedly found in Greece. Meanwhile, at the University of Reading, a research University in Great Britain, the flower is being used for medicinal purposes connected to reducing cholesterol.
High cholesterol levels related to cardiovascular disease have been shown to improve with the help of Artichoke Leaf Extract, or ALE, therefore minimizing the need for prescription drugs. By stabilizing cholesterol before it becomes a problem, researchers at University of Reading found yet another dietary supplement beneficial to healthy cholesterol levels.
More evidence for the beneficial effect of green tea on risk factors for heart disease has emerged in a new study reported in the latest issue of European Journal of Cardiovascular Prevention and Rehabilitation.(1) The study found that the consumption of green tea rapidly improves the function of (endothelial) cells lining the circulatory system; endothelial dysfunction is a key event in the progression of atherosclerosis.
The study, performed by Dr Nikolaos Alexopoulos and colleagues at the 1st Cardiology Department, Athens Medical School in Greece, was a randomised trial involving the diameter measurement (dilatation) of the brachial artery of healthy volunteers on three separate occasions - after taking green tea, caffeine, and hot water (for a placebo effect). The measurements were taken at 30, 90 and 120 minutes after consumption. Dilatation of the brachial artery as a result of increased blood flow (following a brief period of ischaemia of the upper limb) is related to endothelial function and is known to be an independent predictor of cardiovascular risk.(2)
Scientists from Hungary, Germany and the U.K. have discovered that our own body not only makes chemical compounds similar to the active ingredient in marijuana (THC), but these play an important part in maintaining healthy skin.
This finding on "endocannabinoids" just published in The FASEB Journal could lead to new drugs that treat skin conditions ranging from acne to dry skin, and even skin-related tumors.
"Our preclinical data encourage one to explore whether endocannabinoid system-acting agents can be exploited in the management of common skin disorders," said Tamás Biró, MD, PhD, a senior scientist involved in the research. "It is also suggested that these agents can be efficiently applied locally to the skin in the form of a cream."
Almonds, as well as being high in vitamin E and other minerals, are also thought to have other health benefits, such as reducing cholesterol. Recently published work by the Institute of Food Research has identified potential prebiotic properties of almonds that could help improve our digestive health by increasing levels of beneficial gut bacteria.
Our digestive system maintains large population of bacteria that live in the colon. Prebiotics are non-digestible parts of foods that these bacteria can use to fuel their growth and activity. These 'good' bacteria form part of our body's defence against harmful bacteria and play a role in the development of body's immune system. The prebiotics work by stimulating the growth of these bacteria. However, in order to get to where they are needed prebiotics must be able to get through the upper part of the intestine without being digested or absorbed by the body.
Researchers at Bonn University and the ETH Zürich have discovered that oregano, with its active ingredient beta-caryophyllin (E-BCP, docks on specific receptor structures in the cell membrane - the so-called cannabinoid-CB2 receptors, and produces a change in cell behavior: for example, it will inhibit the cell´s production of phlogogenic signal substances.
E-BCP is a typical ingredient of many spices and food plants. Hence it is also found in plants such as basil, rosemary, cinnamon, and black pepper. Every day, we consume up to 200 milligrams of this annular molecule.
The researchers administered E-BCP to mice with inflamed paws and in seven out of ten cases there was a subsequent improvement in the symptoms. E-BCP might possibly be of use against disorders such as osteoporosis and arteriosclerosis.
Just like humans, liver cells love doughnuts, but these are polystyrene ring “doughnuts”, just a few microns across, and they might give scientists a new way to deliver drugs selectively, potentially eliminating nasty side effects of life-saving treatments such as chemotherapy, according to chemists writing in Chemical Communications.
Mark Bradley and colleagues at the University of Edinburgh, UK, serendipitously made the polymer doughnuts while studying potential drug-carrying microparticles.
While synthesising micro-spheres, the team added a small amount of dioxane to their usual ethanol solvent. To their surprise, the resulting microparticles were regular in size and shape, with a hole through the middle like a doughnut.
