Extensive surgery involving mastectomy and removal of several lymph nodes can be safely avoided for more women with some types of breast cancer, if they receive targeted drugs before surgery, according to research presented at the 11th European Breast Cancer Conference. The study focused on women with HER2 positive breast cancer, an aggressive form of the disease, who were given a targeted drug…
A UT Southwestern study in mice provides new clues about how a class of anti-rejection drugs used after organ transplants may also slow the progression of early-stage Alzheimer’s disease. Alzheimer’s, a progressive form of dementia, affects an estimated 5 million people in the U.S. – a number expected to nearly triple by 2050. Although Alzheimer’s usually strikes after age 65, changes in…
Healthy women who carry a breast cancer-causing mutation in the BRCA1 gene, not only reduce their risk of developing the disease but also their chances of dying from it if they have both breasts removed, according to new research presented at the 11th European Breast Cancer Conference. However, the study also found that for women with a mutation in the BRCA2 gene, there was no difference in their…
A compound in beets that gives the vegetable its distinctive red color could eventually help slow the accumulation of misfolded proteins in the brain, a process that is associated with Alzheimer’s disease. Scientists say this discovery could lead to the development of drugs that could alleviate some of the long-term effects of the disease, the world’s leading cause of dementia. The…
Feline AIDS is caused by the Feline Immunodeficiency Virus (FIV), which is very similar to the HIV-1 virus that affects millions of humans. While FIV does not infect humans, many groups research the virus to benefit cats, and perhaps more importantly, because of its many parallels with the AIDS virus. Despite the use of dedicated drugs, HIV-1 manages to thrive and multiply within the cell and…
This year’s unexpectedly aggressive flu season reminds everyone that although the flu vaccine can reduce the number of people who contract the virus, it is still not 100 percent effective. Researchers report that a tweak to a small-molecule drug shows promise for future production of new antiviral therapies that could help patients, regardless of the strain with which they are infected. The…
The decline in cancer of the intestines – colorectal cancer – is one of the major success stories of the past 30 years in Europe say researchers, as they predict that in 2018 death rates from the disease will continue to fall by around seven per cent compared to 2012. In a study published in the leading cancer journal Annals of Oncology, researchers predict that death rates in the European…
The heart is capable of terminating arrhythmias itself after local gene therapy, potentially avoiding the need for patients to undergo painful electric shocks, according to a proof-of-concept study presented today at EHRA 2018, a European Society of Cardiology congress. Atrial fibrillation is the most common heart rhythm disorder (arrhythmia). Treatment aims to restore the heart’s normal rhythm…
Throughout life, DNA is constantly being damaged by environmental and intrinsic factors and must be promptly repaired to prevent mutations, genomic instability, and cancer. Different types of damages are repaired by numerous proteins organized into damage-specific pathways. The proteins from different pathways must be spatially and temporally coordinated in order to efficiently repair complex DNA…
Stephen Hawking, a visionary physicist, as well as a pop culture icon, died March 14 2018 at the age of 76, leaving scientists, doctors, space enthusiasts and “Simpsons” fans alike to reflect on his contributions to modern cosmology and entertainment. Hande Ozdinler, an associate professor in the department of neurology in Northwestern’s Feinberg School of Medicine, reflects on Hawkings…
The idea that it might be possible to be overweight or obese but not at increased risk of heart disease, otherwise known as the “obesity paradox”, has been challenged by a study of nearly 300,000 people published in in the European Heart Journal.
While gastritis and gastric ulcer disease used to be put down to stress and dietary factors, it was discovered in the 1980s that the actual culprit is infection with a bacterium, H. pylori. This pathogen is now classed as a type I carcinogen by the WHO, as it is the major risk factor for development of gastric carcinoma. Attempts to develop a vaccine against H. pylori have been unsuccessful and…
Health chiefs are failing to investigate a clear pattern of rising death rates and worsening health outcomes in England and Wales, argue experts in The BMJ today. Lucinda Hiam at the London School of Hygiene & Tropical Medicine and Danny Dorling at the University of Oxford say weekly mortality figures show 10,375 additional deaths (a rise of 12.4%) in England and Wales in the first seven…
A new imaging technology to grade tumour biopsies has been developed by a team of scientists led by the Department of Physics and the Department of Surgery and Cancer at Imperial College London. Publishing their results in the journal Convergent Science Physical Oncology, they describe how their new method promises to significantly reduce the subjectivity and variability in grading the severity…
For the first time, scientists at Wake Forest Baptist Medical Center have been able to measure a specific molecule indicative of osteoarthritis and a number of other inflammatory diseases using a newly developed technology. This preclinical study used a solid-state nanopore sensor as a tool for the analysis of hyaluronic acid (HA). HA is a naturally occurring molecule that is involved in tissue…
Researchers led by Professor Stefan Pfister from the "Hopp Children's Cancer Center at the NCT Heidelberg" (KiTZ) have been able to draw an extremely detailed molecular map of childhood cancers. In close collaboration with the German Cancer Consortium (DKTK) and the Society for Pediatric Oncology and Hematology (GPOH), they screened almost 1,000 tumor samples from 24 cancer types for…
Scientists at Columbia University’s Mailman School of Public Health developed a system to accurately predict the geographic spread of seasonal influenza in the United States up to six weeks ahead of time.
Holography, like photography, is a way to record the world around us. Both use light to make recordings, but instead of two-dimensional photos, holograms reproduce three-dimensional shapes. The shape is inferred from the patterns that form after light ricochets off an object and interferes with another light wave that serves as a reference. When created with X-ray light, holography can be an…
High levels of vitamin D may be linked to a lower risk of developing cancer, including liver cancer, concludes a large study of Japanese adults published by The BMJ today. The researchers say their findings support the theory that vitamin D might help protect against some cancers. Vitamin D is made by the skin in response to sunlight. It helps to maintain calcium levels in the body to keep bones,…
In standard settings, the analysis of each DNA modification requires a carefully optimised assay that runs under specific conditions. This increases cost and labour and is a severe limitation to throughput. Now, however, researchers at Stanford University and the Technical University of Denmark have come up with a new method that will enable doctors to make a more precise diagnosis, prognosis and…

The 2018 Brain Prize, awarded by the Lundbeck Foundation in Denmark, is worth one million Euros. Awarded annually, it…
A completely new classification of diabetes which also predicts the risk of serious complications and provides treatment suggestions. The major difference from today’s classification is that type 2 diabetes actually consists of several subgroups, the results indicate. “This is the first step towards personalised treatment of diabetes”, says physician and diabetes expert Leif Groop.
Eating fish at least once a week or eating fish one to three times per month in addition to taking daily fish oil supplements may be associated with a reduced risk of multiple sclerosis (MS), according to a preliminary study that will be presented at the American Academy of Neurology’s 70th Annual Meeting in Los Angeles, April 21 to 27, 2018. These findings suggest that the omega-3 fatty acids…
Cell-based biosensors can simulate the effect of various substances, such as drugs, on the human body in the laboratory. Depending on the measuring principle, though, producing them can be expensive. As a result, they are often not used. Cost factors for sensors that perform measurements electrically are the expensive electrode material and complex production. Fraunhofer scientists are now…
People who are frequently exposed to diesel exhaust while on the job may have a higher risk of amyotrophic lateral sclerosis (ALS), and that risk may increase with greater exposure, according to a preliminary study released that will be presented at the American Academy of Neurology’s 70th Annual Meeting in Los Angeles, April 21 to 27, 2018. “There is some suggestion from previous studies of…
