Texas Biomedical Research Institute and The Children’s Hospital of San Antonio have joined forces to cure a mysterious condition called Kawasaki disease. The illness which affects young children is named after the Japanese doctor who first described it more than 50 years ago. However, researchers still do not know what causes the rashes, fever, and artery damage. Some type of infectious agent…
Using self-sampling followed by HPV testing, more than twice as many women at risk of developing cervical cancer could be identified and offered preventive treatment. This is shown by researchers at Uppsala University in the first randomised study in the world comparing two ways of identifying cervical cancer, published in the British Journal of Cancer.
A powerful genome editing tool can be deployed as an ace DNA detective, able to sniff out DNA snippets that signal viral infections, cancer, or even defective genes. This genetic detective, developed in the laboratory of Howard Hughes Medical Institute (HHMI) Investigator Jennifer Doudna at the University of California, Berkeley, uses the genome-slicing system known as CRISPR. By combining the…
Geometry is often referenced for matters of the heart. Marriage has been described as “two parallel lines,” and others have compared love to an “irrational equation” or as unending as “pi.” But when it comes to the medical matters of the heart, geometry can be a lonely and dangerous affair. “The shape and size of a heart is not the same for every person, and a diseased heart, such…
A team of researchers from the Cleveland Clinic Lerner Research Institute have found that gradually depleting an enzyme called BACE1 completely reverses the formation of amyloid plaques in the brains of mice with Alzheimer’s disease, thereby improving the animals’ cognitive function. The study, which will be published in the Journal of Experimental Medicine, raises hopes that drugs targeting…
Scientists have identified a gene that may play a protective role in preventing heart disease. Their research revealed that the gene, called MeXis, acts within key cells inside clogged arteries to help remove excess cholesterol from blood vessels. Published in the journal Nature Medicine, the UCLA-led study in mice found that MeXis controls the expression of a protein that pumps cholesterol out…
Kidney stones are a painful health condition, often requiring multiple procedures at great discomfort to the patient. Growing evidence suggests that the incidence of kidney stones is increasing steadily, especially in women. Using data from the Rochester Epidemiology Project, Mayo Clinic researchers investigated the rise in stone formers to determine if this is a new trend, or simply an…
Watching too much television at age 2 can translate into poorer eating habits in adolescence and poorer performance in school, researchers at Université de Montréal’s School of Psychoeducation have found. In a new longitudinal study published in Preventive Medicine, graduate student Isabelle Simonato and her supervisor, Professor Linda Pagani, looked at a birth cohort of nearly 2,000 Quebec…
A new optical imaging system developed at Columbia University uses red and near-infrared light to identify breast cancer patients who will respond to chemotherapy. The imaging system may be able to predict response to chemotherapy as early as two weeks after beginning treatment. Findings from a first pilot study of the new imaging system—a noninvasive method of measuring blood flow dynamics in…
Avoidance of side-effects of chemotherapy is particularly important in the elderly, but finding the balance between reduced toxicity and maximum effectiveness is not always easy. A trial carried out by the European Organisation for Research and Treatment of Cancer, published in The Lancet Oncology, shows that, in older patients with HER2 positive metastatic breast cancer (an aggressive breast…
Although modern medicine has made progress in the fight against cancer, the fear of cancer diseases is widespread. Still, regular screenings are no matter of course. Only almost every fifth person over 55 years has undergone a colonoscopy even though it is recommend for this age group as cancer prevention. What influences people to undergo these screenings? Screening or not? In making this…
A new genetic study by UK-based scientists suggests that immunotherapy drugs could prove to be an effective treatment for some breast cancer patients. Scientists from the Wellcome Trust Sanger Institute, near Cambridge – one of the world’s leading genome centres – and their collaborators, have identified particular genetic changes in a DNA repair mechanism in breast cancer. Led by Dr Serena…
Will there come a time when a patient with arthritis can forgo joint replacement surgery in favor of a shot? Keck School of Medicine of USC scientist Denis Evseenko, MD, PhD, has reason to be optimistic. In a new publication in the Annals of Rheumatic Diseases, Evseenko’s team describes the promise of a new molecule aptly named “Regulator of Cartilage Growth and Differentiation,” or RCGD…
Scientists at the University of Delaware and the University of Illinois at Chicago have found a new way to kill liver cancer cells and inhibit tumor growth. First, they silence a key cellular enzyme, and then they add a powerful drug. They describe their methods in a new paper published in Nature Communications. This research could accelerate the development of new treatments for liver cancer,…
Indiana University researchers have made an important step forward in the design of drugs that fight the hepatitis B virus, which can cause liver failure and liver cancer. It's estimated that 2 billion people worldwide have had a hepatitis B virus infection in their lifetime, with about 250 million -- including 2 million Americans -- living with chronic infection. Although a vaccine exists, there…
About 15 million Americans don’t have a typical nine-to-five workday, and many of these—nurses, firefighters and flight attendants, among many other professions—may see their schedule change drastically one week to the next. As a result, these shift workers’ biological clocks, which keep track of the time of day, cannot keep accurate time, potentially making the negative effects of a high…
While a couple of glasses of wine can help clear the mind after a busy day, new research shows that it may actually help clean the mind as well. The new study, which appears in the journal Scientific Reports, shows that low levels of alcohol consumption tamp down inflammation and helps the brain clear away toxins, including those associated with Alzheimer’s disease. “Prolonged intake of…
Children's Hospital Los Angeles is announcing participation in the first-ever clinical trial using stem cells from umbilical cord blood to delay or even prevent heart failure in children born with a rare congenital heart defect that leaves them with half a heart. The Phase I study is part of a multi-center collaboration dedicated to employing innovative therapies to improve outcomes for children…
Mutations in the p63 protein lead to a number of disorders, but none is as severe as the AEC syndrome. Scientists at Goethe University Frankfurt in collaboration with a research group from the University of Naples Federico II have now discovered that this syndrome resembles diseases such as Alzheimer’s, Parkinson’s or ALS more closely than it does other p63-based syndromes. Their results,…
People who believe Princess Diana was murdered or that John F. Kennedy’s assassination was an elaborate plot are more likely to think that vaccines are unsafe, despite scientific evidence to the contrary, according to research published by the American Psychological Association. “Vaccinations are one of society’s greatest achievements and one of the main reasons that people live about 30…
Standard medical tests miss nearly two-thirds of heart attack diagnoses, reveals research presented at CMR 2018. “Unrecognised MI has a poor short-term prognosis but until now the long-term outlook was unknown,” said lead author Dr Tushar Acharya, a cardiologist at the National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, US. “This study investigated long-term…
What if one of the prime suspects behind Alzheimer’s disease was a case of mistaken identity? Amyloid plaques, sticky buildup that accumulates in and around neurons in the brain, have long been believed to be an indicator of neurodegenerative disease. Most clinical drug trials for Alzheimer’s disease treatment have failed, presumably because they target these plaques. But according to Raymond…
Tumor imaging technique has potential as anti-cancer weapon, mouse study shows.
Although the incidence of appendicitis in the United States has been in decline for many years, the condition still affects approximately seven percent of Americans annually. A research team at the UND School of Medicine and Health Sciences, found that there is evidence to suggest that a colonoscopy can “prompt” appendicitis up to one week after the procedure, in at least certain patients.
The immune system is a complex and precisely regulated system. Various activating and inhibiting signals ensure that the immune cells combat pathogenic agents without eliciting a potentially harmful response to its own structures and cells. However, if those two forces are imbalanced, the immune cells may attack and damage cells and tissue of the body itself, which will result in the development…
