What Is Health Insurance?
Date: Jul-21-2012Health insurance is a type of insurance coverage that covers the cost of an insured individual's medical and surgical expenses. Depending on the type of health insurance coverage, either the insured pays costs out-of-pocket and is then reimbursed, or the insurer makes payments directly to the provider. In health insurance terminology, the "provider" is a clinic, hospital, doctor, laboratory, health care practitioner, or pharmacy. The "insured" is the owner of the health insurance policy; the person with the health insurance coverage...
New Study Reveals Racial Disparities In Voice Box-Preserving Cancer Treatment
Date: Jul-21-2012A new epidemiological study led by UC Davis researchers reveals significant racial disparities in the use of non-surgical larynx-preservation therapy for locally advanced laryngeal cancer. A review of medical records between 1991 and 2008 from across the country reveals that over 80 percent of white patients received radiation treatment combined with chemotherapy that preserves the larynx, or voice box. Only 74...
Cell Glue Gives Insights Into Cancer
Date: Jul-21-2012University of Queensland researchers have discovered an important step in how proteins glue cells together to form healthy tissues, a process that is often disturbed in diseases such as cancer and inflammation. Professor Alpha Yap, Dr Aparna Ratheesh and Dr Guillermo Gomez from UQ's Institute for Molecular Bioscience (IMB) led a team that discovered the signals that prompt proteins to build the "glue" that binds cells into tissues. "Cells are the basic building blocks of our body," Professor Yap said...
Lab Mice And Rats On All-They-Can-Eat Diet May Lead To Inaccurate Test Results
Date: Jul-21-2012The widespread practice of allowing laboratory rats and mice to eat as much as they want may be affecting the outcome of experiments in which scientists use these "test-tubes-on-four-feet" to test new drugs and other substances for toxicity and other effects. That's the conclusion of a new analysis published in ACS' journal Chemical Research in Toxicology. Laboratory mice and rats serve as stand-ins for people for research that cannot be done on humans...
New Genetic Test Will Mean Faster Diagnosis Of Noonan Syndrome Disorders
Date: Jul-21-2012A new gene test will greatly improve the speed and clarity of diagnosis for a complex range of genetic disorders known as RASopathies. The new test has been developed by molecular diagnostic testing company NewGene in collaboration with the South West Thames Regional Genetics Service at St George's Healthcare NHS Trust in London, the specialist centre for Noonan Syndrome and associated hereditary disorders in the UK. Noonan Syndrome and related disorders (rasopathies) are autosomal dominant congenital syndromes...
People May Be Motivated To Carry Out Unspeakable Acts By Social Identification Rather Than Obedience
Date: Jul-21-2012What makes soldiers abuse prisoners? How could Nazi officials condemn thousands of Jews to gas chamber deaths? What's going on when underlings help cover up a financial swindle? For years, researchers have tried to identify the factors that drive people to commit cruel and brutal acts and perhaps no one has contributed more to this knowledge than psychological scientist Stanley Milgram. Just over 50 years ago, Milgram embarked on what were to become some of the most famous studies in psychology...
Antipsychotic Prescriptions For Dementia Patients Reduced More Than Half Over Last Three Years, England
Date: Jul-21-2012Antipsychotic prescriptions for people with dementia have reduced by 52 per cent in three years, according to an audit carried out by the NHS Information Centre on Tuesday. The audit collected data from more than 3,800 GP practices in England, with information about nearly 197,000 people with dementia. The 52 per cent reduction is between 2008 and 2011. It was also found that there were strong regional variations, with rates of prescribing of antipsychotic drugs up to six times higher in some areas than others...
Discovery Of Anti-Inflammatory Effects Of Abscisic Acid In The Lungs Could Prove Crucial To Healing Influenza
Date: Jul-21-2012Building on previous work with the botanical abscisic acida, researchers in the Nutritional Immunology and Molecular Medicine Laboratory (NIMML) have discovered that abscisic acid has anti-inflammatory effects in the lungs as well as in the gut. The results will be published in the Journal of Nutritional Biochemistry. "While the immune effects of abscisic acid are well understood in the gut, less was known about its effects in the respiratory tract...
Researchers Find Single-Cell Parasites Co-Opt 'Ready-Made' Genes From Host
Date: Jul-21-2012Two species of single-cell parasites have co-opted "ready-made" genes from their hosts that in turn help them exploit their hosts, according to a new study by University of British Columbia and University of Ottawa researchers. Part of a group of parasitic microbes called microsporidia, Encephalitozoon hellem and Encephalitozoon romaleae are related to fungi and are commonly found in the intestines of vertebrates. In humans, they are associated with people with immune deficiencies. The research team identified six genes in these parasites that were not found in any other microsporidian...
Improved Survival For Patients With Chronic Blood Diseases
Date: Jul-21-2012New research from Karolinska Institutet shows that the survival for patients with chronic myeloproliferative diseases has improved in recent decades. This is despite the fact that no targeted drugs have yet been registered for this group of diseases. More than 9,000 patients have been included in a unique population-based study which has been published in the Journal of Clinical Oncology. In Sweden, around 450 people are diagnosed each year with chronic myeloproliferative diseases, a group of three disease subtypes that are characterized by the production of excess cells in the bone marrow...
