In the battle against brain cancer, doctors now have a new weapon: an imaging technology that will make brain surgery dramatically more accurate by allowing surgeons to distinguish between brain tissue and tumors at a microscopic level.
A team of scientists have shown that a protein once thought to inhibit the growth of tumors is instead required for initial tumor growth. The findings could point to a new approach to cancer treatment. The focus of the study was angiomotin, a protein that coordinates cell migration, especially during the start of new blood vessel growth and proliferation of other cell types.
The ability to distinguish between the sounds generated from your own movements and those coming from the outside world is important for learning how to speak or play a musical instrument. Now, researchers have developed the first diagram of the brain circuitry that enables this complex interplay between the motor system and the auditory system to occur.
Phase 1 Clinical Trial (SAV CT 01) of the first and only preventative HIV vaccine based on a genetically modified killed whole virus (SAV001-H) has been successfully completed with no adverse effects in all patients, Western and Sumagen Canada Inc. announced.
Scientists estimate that there is a minimum of 320,000 viruses in mammals awaiting discovery. Collecting evidence of these viruses, or even a majority of them, they say, could provide information critical to early detection and mitigation of disease outbreaks in humans.
For the first time, it has been shown that an intensively active lifestyle can “completely prevent” bad diets from impairing sexual function, says a Johns Hopkins University urology fellow. Put another way, a recent rat study offers strong evidence that erectile dysfunction (ED) is more than just a bedroom bother. It may be one’s own natural biomarker for coronary artery disease.
A precisely designed macromolecule that mimics the binding of HIV to immune system cells could be used to stop the virus from physically entering the body, according to a new study. The researchers created the large molecule with several sugar molecules, known as glycopolymers.
For years, physicians around the world have watched as strain after strain of the deadly bacteria mycobacterium tuberculosis evolves resistance to drugs. A new method of analyzing whole genome sequences of TB, applied to a massive set of strains of the bacteria collected from clinics around the world, has revealed 39 new genes associated with elevated drug resistance.
Here’s a sobering fact for millions of young women heading back to school: The more alcohol they drink before motherhood, the greater their risk of future breast cancer. That’s according to new research from Washington University School of Medicine in St. Louis that, for the first time, links increased breast cancer risk to drinking between early adolescence and first full-term pregnancy.
When a cancer cell sloughs off the edge of a tumor in the breast, it faces a tough road to survive. The cell must not only remain physically intact as it rushes through blood vessels, but it also must find a new organ to lodge itself in, take in enough nutrients and oxygen to stay alive, and begin dividing, all while escaping notice by the body’s immune system.
The age at which children learn a second language can have a significant bearing on the structure of their adult brain, according to a new joint study by the Montreal Neurological Institute and Hospital - The Neuro at McGill University and Oxford University.
Cells in the body wear down over time and die. In many organs, like the small intestine, adult stem cells play a vital role in maintaining function by replacing old cells with new ones. Learning about the nature of tissue stem cells can help scientists understand exactly how our organs are built, and why some organs generate cancer frequently, but others only rarely.
International research with participation of Danish investigators from University of Copenhagen shows that one in four Danes has serious problems with the trillion of bacteria living in their intestines. The problems appear to be associated with increased risk of obesity and diabetes.
Pulmonary hypertension, a deadly form of high blood pressure that develops in the lungs, may be caused by an inflammation-producing molecular pathway that damages the inner lining of blood vessels, according to a new study by researchers at the Stanford University School of Medicine.
Problems with a key group of enzymes called topoisomerases can have profound effects on the genetic machinery behind brain development and potentially lead to autism spectrum disorder (ASD). Scientists at the University of North Carolina School of Medicine have described a finding that represents a significant advance in the hunt for environmental factors behind autism and lends new insights into the disorder’s genetic causes.
Scientists at Albert Einstein College of Medicine of Yeshiva University have shown that high-functioning autism spectrum disorder (ASD) children appear to outgrow a critical social communication disability. Younger children with ASD have trouble integrating the auditory and visual cues associated with speech, but the researchers found that the problem clears up in adolescence.
Four people have been hospitalized and 160 quarantined after a 15-year-old boy who ate marmot meat died of the bubonic plague last week, the Kyrgyz Ministry of Health said today. The ministry in the Central Asian nation said the boy told medics he spent the previous week camping in the mountains where he had eaten barbecued marmot, a large ground squirrel that typically lives in mountainous areas.
HIV-infcted people who carry a gene for a specific protein face a 20-fold greater risk of contracting cryptococcal disease, according to a study. Cryptococcus neoformans is the most common cause of fungal meningitis among HIV-infected individuals.
Coffee consumption is associated with a lower risk of prostate cancer recurrence and progression, according to a new study by Fred Hutchinson Cancer Research Center scientists. They found that men who drank four or more cups of coffee per day experienced a 59 percent reduced risk of prostate cancer recurrence and/or progression as compared to those who drank only one or fewer cups per week.
In the latest in a series of experiments testing the use of stem cells to treat neurological disease, researchers at Henry Ford Hospital have shown for the first time that microscopic material in the cells offers a “robust” treatment for crippling stroke.
A Texas megachurch linked to at least 21 measles cases has been trying to contain the outbreak by hosting vaccination clinics, officials said. The outbreak started when a person who contracted measles overseas visited Eagle Mountain International Church in Newark, located about 20 miles north of Fort Worth, Texas.
Cocaine can speedily rewire high-level brain circuits that support learning, memory and decision-making, according to new research from UC Berkeley and UCSF. The findings shed new light on the frontal brain’s role in drug-seeking behavior and may be key to tackling addiction.
A new study has revealed marked differences in the genomic terrain of the two most common types of cervical cancer, suggesting that patients might benefit from therapies geared to each type’s molecular idiosyncrasies. The study compares the spectrum of cancer-related gene mutations in the two main subtypes of cervical cancer – adenocarcinoma and squamous cell carcinoma.
A new study at Moffitt Cancer Center could offer hope to people with melanoma, the deadliest form of skin cancer. Researchers are investigating whether an injectable known as PV-10 can shrink tumors and reduce the spread of cancer. PV-10 is a solution developed from Rose Bengal, a water-soluble dye commonly used to stain damaged cells in the eye.
Perhaps one of the most defining features of humanity is our capacity for empathy – the ability to put ourselves in others’ shoes. A new University of Virginia study strongly suggests that we are hardwired to empathize because we closely associate people who are close to us – friends, spouses, lovers – with our very selves.
