Dr. Howard, of the University of Ulster, is a fetal toxicologist studying the effects of toxins on the health and development of babies before birth. He pointed out that we are compromising human health from conception by adding fluoride to drinking water. Toxic fluoride compounds are known to affect many other parts of the body including bones, teeth, thyroid as well as the developing brain. The excuse that it helps teeth should be questioned when nearly four in ten Irish teenagers have dental fluorosis -- permanent damage to the tooth enamel -- and this is three times that of their counterparts in unfluoridated Northern Ireland.
Because individuals with both depression and bipolar disorder experience a glutathione deficiency, an antioxidant that protects cells from toxins, researchers in a new study scheduled for publication in the September 15th issue of Biological Psychiatry sought to evaluate whether N-acetyl cysteine (NAC), an over-the-counter supplement that increases brain glutathione, might help alleviate depressive symptoms.
Dr. Michael Berk and colleagues, in a randomized, double-blind, placebo-controlled trial, evaluated the mood symptoms of individuals with bipolar disorder, half of whom received placebo and half of whom received NAC, as an add-on therapy to their usual treatment.
The researchers believe that these results are also applicable to children that have suffered damage due to radiotherapy of brain tumors.
Children that receive radiation treatment for brain tumors often develop learning and memory problems later in life that may be associated with attention deficits. These symptoms have been linked to radiation-induced damage, which not only kills cancer cells, but also stem cells that reside in the hippocampus, a region essential for proper memory function.
In a small pilot study of 20 families, the non-profit environmental group tested blood samples from mothers and their young children -- ages 18 months to four years -- for the presence of PBDEs, a hormone-disrupting chemical.
In 19 of the 20 families, concentrations of PBDEs were typically three times as high in children as in their mothers, said Sonya Lunder, the study's author. One child had six times the level of the chemical that was detected in her mother.
Specialists warned yesterday that UK hospitals are receiving less than half the expected supplies of medical isotopes used in heart and bone scans and some cancer detection procedures, and the situation is expected to worsen over the coming weeks. The isotopes are used in more than 80 per cent of routine nuclear imaging tests used to diagnose disease. Professor Alan Perkins, honorary secretary of the British Nuclear Medicine Society, said: "The expected number of people who will be affected is quite difficult to determine ... but we are certainly talking about hundreds. The procedures include cardiac blood-flow imaging, bone scanning for secondary tumours, lymph-node detection in breast cancer cases and renal function monitoring, which is commonly done in children.
Reports from Mbinga said that about 20 pupils and some adults have been hospitalized at Mbinga District Hospital, after falling sick.
When a person suffers a traumatic experience, environmental cues often become associated with the bad experience. Subsequent exposure to the same cues can cause fear or even panic attacks, according to study author Rainer Reinscheid, an associate professor of pharmacology and pharmaceutical sciences.
The UCI team, along with colleagues from the University of Muenster in Germany, found that a protein called neuropeptide S (NPS) eliminates traumatic responses to bad memories by working on a group of neurons inside the amygdala, the brain region where negative memories are stored.
The new study shows how some Salmonella bacteria use the long stringy appendages they normally use to help them 'swim' and move about to attach themselves to salad leaves and other vegetables, causing contamination and a health risk.

| Professor Frankel believes that as people eat more salads in an effort to be healthy, cases of Salmonella from salad leaves will increase. |
Food poisoning from Salmonella and E. coli is commonly associated with eating contaminated bovine or chicken products, as the pathogens live in the guts of cows and the guts and egg-ducts of chickens, and contamination of meat can occur during the slaughtering process.
However, some recent outbreaks of food poisoning have been associated with contaminated salad or vegetable products, and more specifically, pre-bagged salads. For example, in 2007 a Salmonella outbreak in the UK was traced back to imported basil, and an E. coli outbreak in the USA in 2006 was traced to contaminated pre-packed baby spinach.

In a laboratory study, using fresh human fat tissues, the UC team found that BPA suppresses a key hormone, adiponectin, which is responsible for regulating insulin sensitivity in the body and puts people at a substantially higher risk for metabolic syndrome.
Metabolic syndrome is a combination of risk factors that include lower responsiveness to insulin and higher blood levels of sugar and lipids. According to the American Heart Association, about 25 percent of Americans have metabolic syndrome. Left untreated, the disorder can lead to life-threatening health problems such as coronary artery disease, stroke and type 2 diabetes.
Nira Ben-Jonathan, PhD, and her team are the first to report scientific evidence on the health effects of BPA at environmentally relevant doses equal to "average" human exposure. Previous studies have primarily focused on animal studies and high doses of BPA.
They report their findings in the Aug. 14, 2008, online edition of the journal Environmental Health Perspectives. This scientific data comes just before a key Federal Drug Administration meeting about the safety of the chemical in consumer products scheduled for Sept. 16, 2008.
