Dr. Robert Fuller didn't hesitate to go to Indonesia to treat survivors of the 2004 tsunami, to Haiti to help after the 2010 earthquake or to the Philippines after a devastating typhoon last year. But he's given up on going to West Africa to care for Ebola patients this winter. He could make the six-week commitment sought by his go-to aid organization, International Medical Corps.
Harvard Stem Cell Institute (HSCI) researchers at Massachusetts General (MGH) and Boston Children’s hospitals (BCH) for the first time have used a relatively new gene-editing technique to create what could prove to be an effective technique for blocking HIV from invading and destroying patients’ immune systems.
The UK's International Charter for Space and Major Disasters (the Charter) is an international agreement between space agencies to provide free satellite images in the immediate aftermath of natural or man-made disasters.
Type 2 diabetes and cardiovascular disease appear to have a lot in common. They share risk factors such as obesity and they often occur together. If they also share the same genetic underpinings, then doctors could devise a way to treat them together too. With that hope in mind, scientists applied multiple layers of analysis to the genomics of more than 15,000 women.
A potentially breathable, respiratory vaccine in development has been shown to provide long-term protection for non-human primates against the deadly Ebola virus. Results from a recent pre-clinical study represent the only proof to date that a single dose of a non-injectable vaccine platform for Ebola is long lasting, which could have significant global implications in controlling future outbreaks.
Top medical experts studying the spread of Ebola say the public should expect more cases to emerge in the U.S. by year's end as infected people arrive here from West Africa, including American doctors and nurses returning from the hot zone and people fleeing from the deadly disease. But how many cases?
A new technology that may assist in the treatment of brain cancer and other neurological diseases is the subject of an article in Technology. According to the authors, the current medical use of chemotherapy to treat brain cancer can be inefficient because of the blood-brain-barrier that impedes the delivery of drugs out of blood vessels and into the tumor.
Seizures and migraines have always been considered separate physiological events in the brain, but now a team of engineers and neuroscientists looking at the brain from a physics viewpoint discovered a link between these and related phenomena.
Stanford Univ. School of Medicine researchers have developed a new formula for delivering the therapeutic peptide apelin to heart tissue for treatment of hypertrophy, a hereditary disease commonly attributed to sudden death in athletes. The nanoscale delivery system, which dramatically increases the peptide’s stability, shows promise for treating heart disease in humans, the researchers said.
People with muscular dystrophy could one day assess the effectiveness of their medication with the help of a smartphone-linked device, a new study in mice suggests. The study used a new method to process ultrasound imaging information that could lead to hand-held instruments that provide fast, convenient medical information.
Cancer researchers have found that a simple blood test might help diagnose pancreatic cancer, one of the most deadly forms of the disease. In new research at Indiana Univ., scientists have found that several microRNAs, which are small RNA molecules, circulate at high levels in the blood of pancreatic cancer patients.
U.S. health officials are recommending that people who are at highest risk for coming down with Ebola avoid commercial travel or attending large public gatherings, even if they have no symptoms. The Centers for Disease Control and Prevention issued the updated advice to state and local officials on Monday.
Researchers report in Nature that they have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new avenues of research into thousands of similar molecules, many of which are likely to be medically useful.
Like a slumbering dragon, HIV can lay dormant in a person’s cells for years, evading medical treatments only to wake up and strike at a later time, quickly replicating itself and destroying the immune system. Scientists at the Salk Institute have uncovered a new protein that participates in active HIV replication. The new protein, called Ssu72, is part of a switch used to awaken HIV-1 from its slumber.
In early drug discovery, you need a starting point. In a new research paper published in PLOS-Neglected Tropical Diseases, a team of researchers present hundreds of such starting points for potentially treating Human African trypanosomiasis, or sleeping sickness, a deadly disease that affects thousands of people annually.
The governors of New York and New Jersey are at odds with scientists over Ebola as they back 21-day quarantines for medical workers returning from West Africa, while the nation's top infectious-disease expert warns that such restrictions are unnecessary and could discourage volunteers from aiding disease-ravaged countries.
New achievements in synthetic biology, which will allow complex cellular recognition reactions to proceed outside of living cells, will dare scientists to dream big: There could one day be inexpensive, shippable and accurate test kits that use saliva or a drop of blood to identify specific disease or infection.
The federal government is closing a gap in Ebola screening at airports while states from New York to Texas to California work to get hospitals and nurses ready in case another patient turns up somewhere in the U.S. with the deadly disease. Under the rule going into effect Wednesday, air travelers from the West African nations must enter the U.S. through one of five airports doing special screenings and fever checks for Ebola.
Scientists think of CD8 T cells as long-lived cells that become tuned to fight just one pathogen, but a new study finds that once CD8 T cells fight one pathogen, they also join the body’s “innate” immune system, ready to answer the calls of the cytokine signals that are set off by a wide variety of infections.
Rice Univ. bioengineers have found new evidence of a possible link between diabetes and the hardening of heart valves. A Rice laboratory, in collaboration with the Univ. of Texas Health Science Center at Houston Medical School, discovered that the interstitial cells that turn raw materials into heart valves need just the right amount of nutrients for proper metabolic function.
Federal health officials on Monday issued new guidelines to promote head-to-toe protection for health workers treating Ebola patients. Officials have been scrambling to come up with new advice for protective gear since two Dallas nurses became infected while caring for the first person diagnosed with the virus in the U.S.
European Union nations are working to reach 1 billion euros ($1.27 billion) in aid by the end of the week to fight Ebola in West Africa and are seeking a common approach to the crisis.EU foreign ministers began a week of talks Monday so their 28 leaders can agree by Friday on better measures to fight Ebola, anything from financial aid to common repatriation procedures, more Ebola treatment facilities and better training for health workers.
Ebola fears began to ease for some Monday as a monitoring period passed for those who had close contact with a victim of the disease and after a cruise ship scare ended with the boat returning to port and a laboratory worker on board testing negative for the virus. Federal officials meanwhile ramped up readiness to deal with future cases.
Scientists have used computer simulations to show how bacteria are able to destroy antibiotics, a breakthrough which will help develop drugs which can effectively tackle infections in the future. Researchers at the Univ. of Bristol focused on the role of enzymes in the bacteria, which split the structure of the antibiotic and stop it working, making the bacteria resistant.
The new Urban Dynamics Institute at Oak Ridge National Laboratory is working with the Bill & Melinda Gates Foundation to aid polio vaccination efforts in developing countries. Teams at the institute will apply big data analysis to population dynamics in Nigeria, allowing polio vaccination crews to better estimate the amount of vaccine needed and to target areas of priority, saving time and money in eradicating the disease.
