Despite significant advances, cancer remains one of the predominant causes of mortality in the modern world, and as such has remained a top research priority. It is a complex and continually evolving genetic disease and, as such, requires sophisticated tools for study.
Women treated with radiation for breast cancer are more likely to develop heart problems later, even with the lower doses used today, troubling new research suggests. The risk comes from any amount of radiation, starts five years after treatment and lasts for decades, doctors found.
The Food and Drug Administration has approved a new imaging drug, Lymphoseek, from Navidea Biopharmaceuticals Inc., to help doctors locate lymph nodes in patients with breast cancer and skin cancer.
Vaccines that employ weakened but live pathogens to trigger immune responses have inherent safety issues but researchers have developed a new trick to circumvent the problem— using bacteria’s own cellular mistakes to deliver a safe vaccine.
New research reveals that B cells regulate obesity-associated inflammation and type 2 diabetes through two specific mechanisms.
A new study shows that bitter melon juice restricts the ability of pancreatic cancer cells to metabolize glucose, thus cutting the cells’ energy source and eventually killing them.
The Food and Drug Administration is warning doctors and patients that a widely used antibiotic from Pfizer can cause rare but deadly heart rhythms in some patients. The agency said Tuesday that it is adding new warnings to the label of Zithromax, which is commonly used to treat bronchitis, pneumonia and other infections.
A single concussion may cause lasting structural damage to the brain, according to a new study.
Immune system B cells play a crucial role in the defence of pathogens: When they detect such an intruder, they produce antibodies that help to combat the enemy. They concurrently and continuously improve these molecules to more precisely recognize the pathogens.
Women with atrial fibrilation have more symptoms and lower quality of life than men with the same heart condition, according to an analysis of patients in a large national registry.
Despite many remarkable discoveries in the field of neuroscience during the past several decades, researchers have not been able to fully crack the brain’s “neural code.” Now, biomedical engineering professor Garrett Stanley has presented detailed research progress toward “reading and writing the neural code.”
Explaining children's chronic pain
A new immunoassay that tests for the presence of three biomarkers appears to be a valid screening method for the early detection of malignant kidney cancer, according to new data.
Can the length of strands of DNA in patients with heart disease predict their life expectancy? Researchers who studied the DNA of more that 3,500 patients with heart disease, say yes it can.
Even without modern-day temptations like fast food or cigarettes, people had clogged arteries some 4,000 years ago, according to the biggest-ever study of mummies searching for the condition. Researchers say that suggests heart disease may be more a natural part of human aging rather than being directly tied to contemporary risk factors like smoking, eating fatty foods, and not exercising.
Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers have shown.
Researchers found that traditional methods of fMRI analysis systematically skew which regions of the brain appear to be activating, potentially invalidating hundreds of papers that use the technique.
Some cellular proteins have multiple, and occasionally opposing, functions. Researchers demonstrated that the oncogenic protein SRSF1 can also trigger a stop in cell growth and prevent cancerous proliferation by stabilizing p53, the powerful tumor-suppressor protein.
Researchers have discovered a likely origin of epithelial ovarian cancer (ovarian carcinoma), the fifth leading cause of cancer death among women in the United States.
What makes us happy? Family? Money? Love? How about a peptide? The neurochemical changes underlying human emotions and social behavior are largely unknown.
Anyone whose hand or foot has “fallen asleep” has an idea of the numbness and tingling often experienced by people with peripheral nerve damage. The condition also can cause a range of other symptoms, including unrelenting pain, stinging, burning, itching and sensitivity to touch.
The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability. Now, researchers have reversed the process, recreating a youthful brain that facilitated both learning and healing in the adult mouse.
Saying that the sense of taste is complicated is an understatement, that it is little understood, even more so. Exactly how cells transmit taste information to the brain for three out of the five primary taste types was pretty much a mystery, until now.
In a new study, scientists identified specific key steps in the chain of events that causes stress-related drug relapse. They identified the exact region of the brain where the events take place in rat models and showed that by blocking a step, they could prevent stress-related relapse.
New work from the Broad Institute’s Klarman Cell Observatory, Brigham and Women’s Hospital, Harvard University, MIT, and Yale University expands the understanding of how one type of immune cell—known as a T helper 17 or Th17 cell—develops, and how its growth influences the development of immune responses.
