Health News:Florida study of rare toxin carried by sport fish ♦ 44 Salmonella cases linked to frozen raw breaded chicken ♦ Targeted nanoparticles can overcome drug resistance

Florida study of rare toxin carried by sport fish underscores consumer warnings A rare toxin carried by barracuda, grouper and other locally caught sport fish sickens Floridians in greater numbers than previously believed, a new analysis suggests. Consuming the food borne toxin, called ciguatera, can result in severe nausea and vomiting and sometimes long-term tingling in the limbs or joint pain.
44  Salmonella cases in Canada linked to frozen raw breaded chicken products The Canadian government is warning consumers about the safety of breaded chicken nuggets, chicken burgers and strips after 44 people have been sickened with Salmonella.
Delivering drugs to the right place For the 12 million people worldwide who suffer from polycystic kidney disease (PKD), an inherited disorder with no known cure, a new treatment option may be on the horizon. A targeted drug delivery method has been developed that could potentially slow the progression of polycystic kidney disease
Computer simulation predicts development, progress of pressure sores A computational model that could enhance understanding, diagnosis and treatment of pressure ulcers related to spinal cord injury has been devised by investigators. The team also described results of virtual clinical trials that showed that for effective treatment of the lesions, anti-inflammatory measures had to be applied well before the earliest clinical signs of ulcer formation.
Targeted nanoparticles can overcome drug resistance in trypanosomes Sleeping sickness threatens millions of people in sub-Saharan Africa. The disease is considered fatal if untreated, but treatment options are limited. Existing drugs have serious side effects, and the parasites are developing resistance. A study now reports a new way to circumvent drug resistance and lower the curative dose by delivering existing drugs directly into the parasite.
