Parkinson's Disease Associated With Pesticide Exposure In French Farm Workers
The cause of Parkinson"s disease (PD), the second most frequent neurodegenerative disease after Alzheimer"s disease, is unknown, but in most cases it is believed to involve a combination of environmental risk factors and genetic susceptibility. Laboratory studies in rats have shown that injecting the insecticide rotenone leads to an animal model of PD and several epidemiological studies have shown an association between pesticides and PD, but most have not identified specific pesticides or studied the amount of exposure relating to the association.

In A Chemical Library, Yale Researchers Find Keys To Cell Movement
Rummaging through a biotechnology company"s chemical closet, Yale University researchers found two molecules that will allow scientists to better study how cells move. The study in the journal Nature, published online Aug. 2, describes how two small molecules discovered by Cytokinetics Inc. block the action of a key complex that directs the assembly of actin filaments, which produce the force to help cells move. The target of these inhibitors is the Arp2/3 complex, a cellular component so vital that cells die without it. This dependence has made it challenging to learn exactly which cellular processes depend upon the complex.

Patients Have 'Mixed Views' On Electronic Health Records

Two-thirds of patients are happy for their medical records to be stored electronically, according to a snapshot survey carried out in a community mental health setting. But many patients still have concerns about security and confidentiality. Psychiatrists Dr Sulagna Chakrabarti, Dr Claire Dinnis and Dr Samina Matin surveyed 90 patients attending a community mental health team setting. They present their findings today at the Royal College of Psychiatrists" Annual Meeting in Liverpool. England is in the process of developing an electronic records system called the NHS Care Records Service (NHS CRS). The aim is to provide more efficient and safer care for patients. This system will eventually replace paper records and is based on an assumption of consent to them being electronically held. The NHS Code of Practice requires that all patients must be made aware that the information they give may be recorded; may be shared in order to provide them with care; and may be used to support local clinical audit and other work to monitor the quality of care provided. RiO is a computerised system for sharing electronic healthcare records and it is important to ensure all service users are well informed about its use. This audit was carried out to test that this was being carried out effectively. The researchers found the majority of patients surveyed were aware that their medical records are now being stored electronically. Almost two-thirds (65%) of the patients said they were happy for their records to be stored this way, and thought the computer technology was acceptable. However, they did express concerns about security, confidentiality and the potential exploitation of their records. The researchers said: "Patients have strong views with regards to consent and what they find acceptable. More work is required to address legal and ethical issues of electronic health records, and to evaluate their impact on patients, health professionals and service provision."
