In Australia, Where Not To Have A Heart Attack
Date: Jun-01-2012Every single town in Australia has been rated on its proximity to cardiac care, before and after a heart attack, in a new report published in Circulation and headed by Queensland University of Technology (QUT). Associate Professor Robyn Clark, from QUT's School of Nursing, led a national research team for the seven-year multi-disciplinary project, entitled the Cardiac Accessibility and Remoteness Index for Australia (Cardiac ARIA), with funding from an Australian Research Council Linkage Grant and linkage partner AlphaPharm Pty Ltd...
Patients With Bipolar Depression Benefit From Ketamine Within Minutes
Date: Jun-01-2012Bipolar disorder is a serious and debilitating condition where individuals experience severe swings in mood between mania and depression. The episodes of low or elevated mood can last days or months, and the risk of suicide is high. Antidepressants are commonly prescribed to treat or prevent the depressive episodes, but they are not universally effective. Many patients still continue to experience periods of depression even while being treated, and many patients must try several different types of antidepressants before finding one that works for them...
Increased Risk Of Heart Rhythm Dysfunction, Sudden Death Caused By Genetic Variant
Date: Jun-01-2012Cardiovascular researchers at the University of Cincinnati (UC) have identified a genetic variant in a cardiac protein that can be linked to heart rhythm dysfunction. This is the first genetic variant in a calcium-binding protein (histidine-rich calcium binding protein) found to be associated with ventricular arrhythmias and sudden cardiac death in dilated cardiomyopathy patients, opening up new possibilities for treatment. Dilated cardiomyopathy is a condition in which the heart becomes weakened and enlarged and cannot pump blood efficiently...
A Simple Cooler Could Help Patients Battle Antibiotic-Resistant Tuberculosis
Date: Jun-01-2012Tuberculosis, now largely controlled in the industrialized world, remains a stubbornly persistent killer in most of Africa, as well as parts of Asia and South America. The spread of multidrug-resistant strains of TB has slowed progress against the devastating disease, which is estimated to strike more than 10 million people annually. Now a modified soft-drink cooler, developed by researchers at MIT's D-Lab, could make a dent in the disease's impact. There are two big issues that physicians confront in trying to tackle drug-resistant TB strains in developing countries...
After Cancer Diagnosis, Men And Women Receive Different Fertility Advice
Date: Jun-01-2012There are significant gaps in the information women receive about their future fertility following cancer diagnosis, suggests a new paper published in BJOG: An International Journal of Obstetrics and Gynaecology. Infertility can be a side-effect of cancer treatment and there are increasing numbers of people of reproductive age undergoing such treatment. This study - led by the University of Aberdeen and NHS Grampian - looks at perceptions and use of fertility preservation techniques in both men and women of reproductive age who have recently been diagnosed with cancer...
Drug-Resistant Bacteria Destroyed By Light-Induced Delivery Of Nitric Oxide
Date: Jun-01-2012Researchers at the University of California, Santa Cruz, have developed a novel approach for eradicating drug-resistant bacteria from wounds and skin infections, using light to trigger the controlled release of nitric oxide. The UCSC team developed a photoactive compound that releases nitric oxide when exposed to light, and loaded it into a porous, biocompatible material that could be applied as a sprayable powder...
Breast Stem-Cell Research Reveals Receptor Teamwork Required, Possible Involvement Of New Pathway
Date: Jun-01-2012Breast-cancer researchers at the University of Wisconsin-Madison have found that two related receptors in a robust signaling pathway must work together as a team to maintain normal activity in mammary stem cells. Mammary stem cells produce various kinds of breast cell types. They may also drive the development and growth of malignant breast tumors. Published recently in the Journal of Biological Chemistry, the research also suggests that a new signaling pathway may be involved, a development that eventually could take cancer-drug manufacturers in a new direction...
Study Compares The Epigenetic Markers Of A Healthy Person And One With A Genetic Disease
Date: Jun-01-2012A study led by Manel Esteller, director of the Epigenetics and Cancer Biology Program at the Bellvitge Biomedical Research Institute (IDIBELL), professor of genetics at the University of Barcelona and ICREA researcher has completed the first epigenome in Europe. The finding is published in the international scientific journal Epigenetics. The genome of all cells in the human body is the same for all of them, regardless of their aspect and functions. Therefore, genome cannot fully explain the activity of tissues and organs and their disorders in complex diseases like cancer...
The Criminal Justice System May Be Treating Female Sex Offenders More Leniently Than Men
Date: Jun-01-2012Female sex offenders receive lighter sentences for the same crimes than males says a study recently published in Feminist Criminology, a SAGE journal and the official journal of the Division on Women and Crime of the American Society of Criminology. Embry and Lyons looked at the sentences that male and female sex offenders received for specific sex offenses and found that even after the implementation of sentencing guidelines to ensure equality in sentencing, on average male sentences were between 6% and 31% longer than female sentences for the same or similar crimes...
Development Of Synthetic Platelets
Date: Jun-01-2012Synthetic platelets have been developed by UC Santa Barbara researchers, in collaboration with researchers at Scripps Research Institute and Sanford-Burnham Institute in La Jolla, Calif. Their findings are published in the journal Advanced Materials in a paper titled "Platelet Mimetic Particles for Targeting Thrombi in Flowing Blood." Platelets are the components of blood that allow it to prevent excessive bleeding and to heal wounds. The unique physical and biochemical properties of platelets play an important role in performing these complex biological tasks...
