Autism-related genetic mutations occur in aging brains of Alzheimer’s patients

26.11.2019 Health Problems

Researchers believe that autism is caused by mutations that occur sporadically in the egg or sperm or during pregnancy. Activity-dependent neuroprotective protein (ADNP) is a dominant gene whose de novo (during pregnancy) mutations are known to cause autism-related intellectual disabilities. A new Tel Aviv University study has found that ADNP mutations continue to occur in old age and accumulate in […]

Scientists identify the cells behind nicotine aversion in the mouse brain

26.11.2019 Health Problems

If you have ever smoked, or know someone who has—they might tell you that smoking a cigarette probably felt disgusting at first. Taryn Grieder has a personal interest in understanding why people continue to smoke despite the initial revulsion and countless health risks. “In my family we have six people and five of us—everyone but me—smoke, or at least they […]

‘Magic bullet’ takes aim at pancreatic cancer

25.11.2019 Health Problems

Every day, more than 1200 people worldwide are told they have pancreatic cancer. Within 12 months, 80 per cent of them will have succumbed to the disease. It’s one of the most lethal cancers in the world but new research from the University of South Australia could help vastly improve the prognosis for pancreatic cancer patients. Using a new targeted […]

More polio cases now caused by vaccine than by wild virus

25.11.2019 Health Problems

Four African countries have reported new cases of polio linked to the oral vaccine, as global health numbers show there are now more children being paralyzed by viruses originating in vaccines than in the wild. In a report late last week, the World Health Organization and partners noted nine new polio cases caused by the vaccine in Nigeria, Congo, Central […]

How an AI solution can design new tuberculosis drug regimens

22.11.2019 Health Problems

With a shortage of new tuberculosis drugs in the pipeline, a software tool from the University of Michigan can predict how current drugs—including unlikely candidates—can be combined in new ways to create more effective treatments. “This could replace our traditional trial-and-error system for drug development that is comparatively slow and expensive,” said Sriram Chandrasekaran, U-M assistant professor of biomedical engineering, […]

Trials promise good news for countries with dengue and Zika virus

21.11.2019 Health Problems

An international team of scientists have reported an effective and environmentally sustainable way to block the transmission of mosquito-borne dengue virus, in trials carried out in Malaysia. The breakthrough has major implications for countries with hot climates such as island nations in the South Pacific to Saudi Arabia, Africa and South America, all of which experience dengue, Zika, yellow fever […]

Does frailty affect outcomes after traumatic spinal cord injury?

21.11.2019 Health Problems

A new study has shown that frailty is an important predictor of worse outcome after traumatic spinal cord injury in patients less than 75 years of age. In patients younger than 75 years, frailty was a predictor of adverse events, acute length of stay, and in-hospital mortality, as reported in an article published in Journal of Neurotrauma. “The Effect of […]

The high cost challenge of personalised screening for bowel cancer

21.11.2019 Health Problems

Personalised screening could improve the diagnosis of bowel cancer and re-shape the future of Australia’s National Bowel Cancer Screening Program (NBCSP), according to new research at The University of Western Australia. The study, published today in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research, hopes to improve health outcomes by targeting screening at those […]

Eastern equine encephalitis virus poses emergent threat, say NIH officials

21.11.2019 Health Problems

Although eastern equine encephalitis (EEE), a mosquito-borne illness, has existed for centuries, 2019 has been a particularly deadly year for the disease in the United States. As of November 12, 36 confirmed cases of EEE had been reported by eight states; 13 of these cases were fatal. In a new commentary in the New England Journal of Medicine, officials from […]

Probing the role of an inflammation resolution sensor in obesity and heart failure

20.11.2019 Health Problems

After heart attack injury, several fatty-acid-derived bioactive molecules—including one called resolvin D1—play an essential signaling role to safely clear inflammation and help repair heart muscle. The mechanism of how this resolution occurs is not well-understood. There is a receptor on the surface of many immune cells called ALX/FRP2, and in models of atherosclerosis, ALX/FPR2 is known to act as a […]
