A new analysis reports on the history and stakeholders behind the drugs.
Researchers have created a way to transform the dead bone of a transplanted skeletal graft into living tissue in an experiment involving mice.
EU researchers based in the US have given an outstanding "yes" to the creation of a network for them and about them. Following a survey of researchers from EU countries working in the US, carried out by the European Commission, over 90% of the 2000 respondents said that they wanted closer research links with Europe.
A new study on whether the model used to identify patients most in need of a liver transplant can be improved upon found that measuring serum sodium in potential transplant patients helps to better predict those with a poor prognosis.
A new study investigating the effects of the major flavonoid component of green tea on hepatic steatosis (fatty liver) found that it significantly protected livers that suffered ischemia/reperfusion (I/R) injury in mice. I/R injury, which is caused by decreased blood flow, can lead to complications after liver transplantation.
A saliva test can predict whether children will develop cavities later in life, USC researchers say.
Men middle-aged and older routinely get blood tests for prostate-specific antigen, or PSA, to screen for prostate cancer. However, many men with elevated PSAs don't have prostate cancer and undergo unnecessary biopsies, which can cause infertility, incontinence, and impotence. Other men do have prostate cancer, but have normal PSAs, allowing the cancer to spread undetected. A preliminary study from Children's Hospital Boston shows that a simple urine test may improve upon PSA screening.
A majority of Americans believes it is appropriate to use reproductive genetic testing to avoid having a child with a life-threatening disease, or to test embryos to see if they will be a good match to provide cells to help a sick sibling, a new report of the Genetics and Public Policy Center reveals. However, most Americans believe it would be wrong to use genetic testing to select the sex or other non-health related, genetic characteristics of a child.
Bigger is smarter is better. That's the conventional wisdom for why the human brain gradually became three times larger than the ancestral brain. But bigger brains were not generally smarter brains. Archaeological records indicate our ancestors went through two periods of more than a million years each in which tool-making techniques didn't gradually improve, despite a gradual brain size increase.
Shared properties of human languages are not the result of universal grammar but reflect self-organizing properties of language as an evolving system.
Researchers have noted a higher incidence of depression among patients with epilepsy than the general population or others with chronic conditions such as diabetes. For a long time, depression was thought to be a complication of epilepsy.
Women who have suffered a heart attack or have chest pain are being prescribed appropriate drug intervention at hospital discharge at the same frequency as men, researchers reported at the Second International Conference on Women, Heart Disease and Stroke.
The Methodist Hospital and University of Houston System signed a 30-year agreement for formalized collaborations. The two institutions will jointly develop health service/education programs and participate in research efforts and technology transfer. The agreement calls for both institutions to share facilities for research, training and education of health professionals, graduate students, postdoctoral fellows and interns/residents. Faculty of The Methodist Hospital Research Institute and of UH System will be eligible for appointments at both institutions.
A widely-used class of drugs that keep the HIV-virus infection from progressing to AIDS may cause serious and potentially lethal heart rhythm disturbances in some patients. The finding of a Mayo Clinic-led investigation appears in the current edition of The Lancet (http://www.thelancet.com/home).
The American Society of Human Genetics (ASHG) joins advocacy groups and professional societies in applauding the Senate for passing the Genetic Non-discrimination bill.
Rice University is hosting a conference titled "Frontiers of Medicine: Society, Pharmacology and Membrane Biology in the Genomic Era" in Houston March 7-9. The program will examine the changing role of medicine in society, the future of drug discovery, and research on the membrane proteins and lipids that form the drug-targeted boundary between cells and their environment.
Bridging gaps between medicine, biology, materials science, public policy and nanotechnology to provide new clinical approaches for saving lives, the Alliance for NanoHealth is holding a workshop Wednesday, Feb. 23, hosted by the University of Houston. The conference will promote networking and new research opportunities among researchers at regional institutions focused on research collaborations and advancements in bioanalytics, nanotechnology and bioinformatics. How nanohealth research may meet needs of NASA exploration missions also will be discussed.
For the first time, scientists have shown precisely how weather conditions cause multiple populations of a species within a large geographical area to have simultaneous increases or decreases in their abundance, a process known as "spatial synchrony." The research reveals that occasional severe weather conditions directly cause the rapid increase or decrease in abundance of a parasite that infects an important game bird, causing them all to either decline or thrive simultaneously in breeding success.
Michigan State University researchers have found that a certain gene, expressed within a human adult stem cell, could hold the key to not only offering new hope to cancer patients, but also to answering the question of how cancer originates.
Hospital water is a significant source of microbial contamination contributing to the increase of nosocomial (hospital-acquired) infections worldwide, a leading cause of morbidity and mortality especially among immunocompromised patients. To address the problem, Pall Corporation (NYSE: PLL) is introducing in Europe the Pall-AquasafeTM AQF1C water filter, the latest addition to its line of point-of-use water filters for hospitals and other healthcare facilities.
Mayo Clinic researchers have found that obese individuals in otherwise good health who donated a kidney had outcomes similar to their non-obese counterparts. The study is published in the March issue of the American Journal of Transplantation.
A new study will test an FDA-approved antidepressant for its potential to alleviate bladder pain for which there is no known cause and no effective therapy. Thousands, if not millions, of patients may benefit. The study is funded by the National Institutes of Health (NIH).
For nearly a decade, scientists have been trying to fully understand a particular communication pathway inside of cells that contributes to many malignant brain and prostate cancers. While scientists have identified elements of this pathway, other key components have remained a mystery. Researchers at Whitehead Institute now have discovered a missing puzzle piece, a finding that may present drug makers with a significant new cancer target.
This issue includes the following articles: 'New Coronavirus Identified in Bats,'New Test May Differentiate Between Poultry Vaccinated Against or Infected with Avian Flu,' and 'Salmonella spp. Prevalent in Oysters in US Waters.'
Three commonly used drugs -- Prozac, Xenical and Meridia -- may help type 2 diabetes patients lose small amounts of weight, although long-term benefits are not clear, a new review of 22 studies suggests.
