New method of oral vaccination could help boost immunity to TB, influenza and C. difficile

Scientists at Royal Holloway, University of London have developed a pioneering new method of oral vaccination which could help boost immunity to TB and influenza, as well as prevent C. difficile for which there is currently no vaccine.

NIH conference to assess GDM screening and diagnostic approaches

Gestational diabetes mellitus (GDM) is a condition in which women without previously diagnosed diabetes exhibit high blood glucose levels during pregnancy (especially during the third trimester of pregnancy). It is defined as carbohydrate intolerance, which is the inability of the body to adequately process carbohydrates (sugars and starches) into energy for the body, that develops or is first recognized during pregnancy.

Scientists develop new breast cancer screening method with less radiation

Scientists have developed a way to produce three-dimensional X-ray images of the breast at a radiation dose that is lower than the 2D radiography methods used in clinics today. The new method enables the production of 3D diagnostic computed tomography (CT) images with a spatial resolution 2-3 times higher than present hospital scanners, but with a radiation dose that is about 25 times lower.

Rapid and point-of-care tests accurate, convenient for hepatitis C screening

Rapid and point-of-care screening tests for hepatitis C have a high accuracy and quick turnaround time, suggest results of a systematic review and meta-analysis.

Novel approach to assemble the 'connectome' via genetic barcoding

A team of neuroscientists has proposed a new and potentially revolutionary way of obtaining a neuronal connectivity map (the "connectome") of the whole brain of the mouse. The details are set forth in an essay published October 23 in the open-access journal PLOS Biology.

Research team finds elusive self-healing formulation for defense, aerospace

A research team at the University of Nevada, Reno has developed a new environmentally-friendly coating for aluminum to replace the carcinogenic chromate coatings used in aerospace applications. The chromate conversion coatings have been used for more than 50 years to protect aluminum from corrosion.

New project aims to devise programs that help reduce risk of cancer

Most people know that smoking, a bad diet, and physical inactivity can lead to catastrophic personal health consequences, including cancer. Yet millions continue to smoke, eat poorly, and fail to get enough exercise.

Metabolic pathway for insulin effects of sleep identified

Sleep deprivation reduces insulin sensitivity in human fat cells, which could, over time, lead to metabolic disorders such as diabetes, researchers report.

Combination of phase contrast tomography and EST can produce high-quality 3D breast images

Like cleaning the lenses of a foggy pair of glasses, scientists are now able to use a technique developed by UCLA researchers and their European colleagues to produce three-dimensional images of breast tissue that are two to three times sharper than those made using current CT scanners at hospitals. The technique also uses a lower dose of X-ray radiation than a mammogram.

Researchers investigate effects of sleep architecture on hunger

A new study shows that both length of time and percentage of overall sleep spent in different sleep stages are associated with decreased metabolic rate, increased hunger, and increased intake of calories (specifically from fat and carbohydrates). The findings suggest an explanation for the association between sleep problems and obesity.

New Northwestern study focuses on 'pre-feelings' and ability to anticipate the near future

Wouldn't it be amazing if our bodies prepared us for future events that could be very important to us, even if there's no clue about what those events will be?

Blood-circulating monocytes can replace brain resident microglia

The immune system is comprised of multiple cell types each capable of specialized functions to protect the body from invading pathogens and promote tissue repair after injury. One cell type, known as monocytes, circulates throughout the organism in the blood and enters tissues to actively phagocytose (eat!) foreign cells and assist in tissue healing.

Researchers discover how HIV-infected people develop very powerful antibody responses

Wits researchers have played a pivotal role in an AIDS study published today in the journal, Nature Medicine, which describes how a unique change in the outer covering of the virus found in two HIV infected South African women enabled them to make potent antibodies which are able to kill up to 88% of HIV types from around the world.

Case reports highlight importance of vitamin and mineral supplementation after bariatric surgery

Non-compliance with vitamin and mineral supplementation protocols after bariatric surgery could lead to nutritional deficiencies and related health complications, such as heart damage, according to two separate case reports unveiled today at the American College of Gastroenterology's (ACG) 77th Annual Scientific meeting in Las Vegas.

Link between marijuana use and cannabinoid hyperemesis

Marijuana use-both natural and synthetic-may cause cannabinoid hyperemesis (CH) a little-known but costly effect that researchers suggest is a serious burden to the health care system as it often leads to expensive diagnostic tests and ineffective treatments in an effort to find the cause of a patient's symptoms and provide relief, according to two separate case reports unveiled today at the American College of Gastroenterology's (ACG) 77th Annual Scientific meeting in Las Vegas.

Possible overlap exists between inflammatory bowel disease and IBS

Research unveiled today at the American College of Gastroenterology's (ACG) 77th Annual Scientific meeting in Las Vegas suggests a possible overlap of symptoms of two prevalent GI disorders: irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) and further suggests a possible link between subtle GI tract inflammation and IBS symptoms-a link that is also the focus of the first systemic review of the literature on this topic and an editorial both published in this month's American Journal of Gastroenterology.

Breast cancer spread dependent on both environment and genetic changes

A new study from Johns Hopkins researchers suggests that the lethal spread of breast cancer is as dependent on a tumor’s protein-rich environment as on genetic changes inside tumor cells.

Glioblastoma multiforme can originate from cortical neurons

Scientists have long believed that glioblastoma multiforme (GBM), the most aggressive type of primary brain tumor, begins in glial cells that make up supportive tissue in the brain or in neural stem cells. In a paper published October 18 in Science Express, however, researchers at the Salk Institute for Biological Studies have found that the tumors can originate from other types of differentiated cells in the nervous system, including cortical neurons.
