Experts from the Universities of Bath and Seville have carried out a series of experiments by which, for the first time, they have characterized the normal electrical activity in PC-3 prostate cancer cells in real time, with a resulting low-frequency electrical pattern between 0.1 and 10 Hertz. “We have observed that this electrical activity evolves

A research team based at Tokyo Medical and Dental University (TMDU) has used an integrated data analysis to classify hepatocellular carcinoma, the most common type of liver cancer, into three distinct subgroups, which should aid targeted treatment Liver cancer remains a major problem in healthcare globally, being the second most common cause of cancer-related death

When daylight saving time ends in late fall, it is common to start experiencing an onset of mild depressive feelings and tendencies, often coined as “winter blues.” Energy levels seem to decrease with the temperature drop, people tend to feel more tired and sluggish, and there is an element of dread that occurs when one’s

Many South Asian immigrants from countries where tuberculosis (TB) is common do not get tested even though they are at high risk for developing the disease, according to a recent study by Rutgers University and St. Peter’s University Hospital. Tuberculosis, which mainly affects the lungs, kills more people worldwide—about 1.6 million—than any other single infectious

A network of very fine blood vessels that connects bone marrow directly with the blood supply of the periosteum that was previously overlooked has now been discovered by Dr. Anika Grüneboom, a young researcher who is now working at Universitätsklinikum Erlangen. She made this groundbreaking discovery while working on her doctoral thesis at Universität Duisburg-Essen

Females find same-sex social interactions to be more rewarding than males, and females are more sensitive to the rewarding actions of oxytocin (OT) than males, according to a research study led by Georgia State University on the brain mechanisms that determine the rewarding properties of social interactions. “Recognizing gender differencess in social reward processing is

Admission to hospital with a heart attack outside normal working hours does not appear to increase a patient’s chance of dying in hospital, according to a study of more than 600,000 patient cases. The new research suggests that fears about potential differences in outcomes depending on the time of hospital admission may be unfounded. Led

When we’re in pain, we have a hard time sleeping. But how does poor sleep affect pain? For the first time, scientists at the University of California, Berkeley, have answered that question by identifying neural glitches in the sleep-deprived brain that can intensify and prolong the agony of sickness and injury. Their findings, to be

The first and most distinct consequence of daily mild stress is an increase in rapid-eye-movement (REM) sleep, a new study in the journal PNAS reports. The research also demonstrated that this increase is associated with genes involved in cell death and survival. REM sleep, also known as paradoxical sleep, is the sleep state during which

New strides are being made toward the ex vivo growth of human lungs. In a new article published in Tissue Engineering, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers, researchers report the development of a high-throughput, automated, multichannel lung bioreactor that allows parallel culture of up to five human cell-populated isolated rat lung scaffolds.

A team of researchers from Memorial Sloan Kettering Cancer Center and Weill Cornell Medical College used genetic testing of cells found in cerebrospinal fluid to track certain brain tumors. In their paper published in the journal Nature, the group describes tests they conducted with cancer patients and analysis of their cerebrospinal fluid, and what they

Scientists have identified an enzyme that is a “master regulator” of kidney function that if excessively suppressed, can trigger renal failure. Their findings have implications for the use of existing drugs and the development of new pharmaceuticals. As reported in Nature Communications, a global research team led by the University of Bristol studied how the

Permanently arrested cell growth is known as “cellular senescence”, and the accumulation of senescent cells may be one cause of aging in our bodies. Japanese researchers have discovered that a certain enzyme in our bodies promotes cellular senescence by producing reactive oxygen species. Drugs that target this enzyme could potentially suppress this process, and inhibit

A new drug shows potential to halt cancer cells’ growth by stunting the cells’ biological clock. The findings from scientists at the USC Michelson Center for Convergent Bioscience and Nagoya University’s Institute of Transformative BioMolecules (ITbM) advance a burgeoning area of research: turning the body’s circadian rhythms against cancer. Their study, conducted on human kidney

PSA screening cuts deaths from prostate cancer by some 30 percent. This research was based on data of 20,000 men monitored for more than two decades. The men’s initially measured PSA levels proved highly significant as a predictor of future cancer risk. “This research is important, because it shows the long-term effects of an organized

Previous infection with dengue virus may protect children from symptomatic Zika, according to a study published January 22 in the open-access journal PLOS Medicine by Eva Harris of the University of California, Berkeley, and colleagues. Zika virus emerged in northeast Brazil in 2015 and spread rapidly across the Americas, affecting populations that have been largely

Knowing who needs to be where, on what day and at what time. Buying a bigger pair of pants before a child outgrows what is currently hanging in the closet. Always having a jar of unopened peanut butter on hand. These caregiving tasks require mental and emotional effort and are examples of the invisible labor

The journey of muscle rehabilitation can be long and arduous, and requires strong perseverance from the patient. Now, researchers from the National University of Singapore (NUS) are making the recovery process much easier for patients with an ingenious medical device capable of regenerating muscles in a non-invasive and painless manner. The device, named MRegen, makes

THOUSAND OAKS, Calif. and BRUSSELS, Jan. 16, 2019 /PRNewswire/ — Amgen (NASDAQ:AMGN) and UCB (Euronext Brussels: UCB) today announced strong support from the U.S. Food and Drug Administration (FDA) Bone, Reproductive and Urologic Drugs Advisory Committee (BRUDAC) for the approval of Evenity™* (romosozumab) for the treatment of postmenopausal women with osteoporosis at high risk for

Korean researchers have identified the inhibition of autophagy in microglia, brain immune cells. It is expected to help develop treatments for Alzheimer’s disease which occur due to the inhibition of autophagy. Alzheimer’s disease (AD) is the most representative degenerative brain disease, accounting for 60 to 80 percent of all dementia cases. In search for new
