Pancreatic cancer risk linked to differences in telomeres' length in blood cells

A new study shows that a blood marker is linked to pancreatic cancer, according to a study published today by scientists at the University of Wisconsin Carbone Cancer Center and Mayo Clinic.

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.

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.

GSU project to study how the body's internal clock is reset

Georgia State University's H. Elliott Albers, the Regents' Professor of Neuroscience and director of the Center for Behavioral Neuroscience, has received a four-year, $1.3 million grant from the National Institutes of Health to study how the body's internal clock is "reset," a key to understanding more about sleep and other disorders affecting human health.

Researchers increase potency of a compound that reactivates antibiotics against MRSA

Researchers from North Carolina State University have increased the potency of a compound that reactivates antibiotics against methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant form of Staphylococcus that is notoriously difficult to treat. Their improved compound removes the bacteria's antibiotic resistance and allows the antibiotic to once again become effective at normal dosage levels.

Study still implicates amyloid beta in causing Alzheimer's dementia

Researchers at Washington University School of Medicine in St. Louis have found a key difference in the brains of people with Alzheimer's disease and those who are cognitively normal but still have brain plaques that characterize this type of dementia.

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?

KIF3A protein ferries HIV to the plasma membrane

A study in The Journal of Cell Biology identifies a motor protein that ferries HIV to the plasma membrane, helping the virus escape from macrophages.

Austrian researchers receive $7.4 million award to verify new breast cancer pathways

The innovator's award recognises Josef Penninger's work in identifying a key molecular pathway how hormone replacement therapies and contraceptive pills can lead to breast cancer. His team provided the first genetic proof that a protein called RANKL is the master regulator of bone loss, which has contributed to the development of a novel drug already approved for the treatment of osteoporosis and skeletal related events in multiple cancers.

Study looks at DNA sequences for receptors in T lymphocytes

Our immune system must be tremendously complex to respond to the unending assault of viruses, bacteria and cancerous cells. One of the mechanisms used by the immune system to cope with the huge variety of possible threats is to randomly combine DNA segments for the production of receptors on lymphocytes - a type of white blood cell.

X-ray technology improves early detection of pulmonary disease

Chronic obstructive pulmonary disease (COPD) is considered the fourth most common cause of death in the United States. Usually the precursor to this life-threatening lung disease is a chronic bronchitis. Partially destroyed alveoli and an over-inflation of the lungs, known as emphysema, are serious side effects. However, the subtle differences in the tissue are barely discernable in standard X-ray images.

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.

Bodyguard macrophages protect stem cells from over-differentiation

Hiding deep inside the bone marrow are special cells. They wait patiently for the hour of need, at which point these blood forming stem cells can proliferate and differentiate into billions of mature blood immune cells to help the body cope with infection, for example, or extra red blood cells for low oxygen levels at high altitudes. Even in emergencies, however, the body keeps to a long-term plan: It maintains a reserve of undifferentiated stem cells for future needs and crises.

Exposure to short-wavelength blue light enhances CAR in sleep deprived adolescents

Adolescents can be chronically sleep deprived because of their inability to fall asleep early in combination with fixed wakeup times on school days. According to the CDC, almost 70 percent of school children get insufficient sleep—less than 8 hours on school nights.

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.

Exercise may protect the brain from age-related changes

People who exercise later in life may better protect their brain from age-related changes than those who do not, a study suggests.

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.

CAMH scientists identify potential new approach to prevent smoking relapse

Scientists at the Centre for Addiction and Mental Health (CAMH) have identified a potential new approach to preventing smoking relapse, which occurs frequently in smokers who attempt to quit, despite current treatments.

CSF biomarkers can differentiate patients with Alzheimer's or Parkinson disease

Analysis of specific biomarkers in a cerebrospinal fluid sample can differentiate patients with Alzheimer's disease from those with other types of dementia. The method, which is being studied by researchers at Sahlgrenska Academy, may eventually permit earlier detection of Alzheimer's disease.
