A sweet step toward new cancer therapies

...cancer diagnosis and treatment options. A growing body of evidence points to assemblies of sugars called glycans attached to proteins on cancer cell surfaces as accomplices in the growth and spread of tumors. Researchers have been keen to characterize these glycans, but traditional analytical methods hav...

Light wine intake is associated with longer life expectancy in men

... surveys included drinking habits, dietary habits, body mass index, smoking habits and the prevalence of heart attack, stroke, diabetes and cancer. The statistics on alcohol consumption were adjusted to account for other risk factors. The researchers found that long-term, light alcohol intake of less t...

Common cold virus may kill breast cancer cells

...d radiation treatment, which also impact on normal body cells. "In theory, the virus is able to selectively target and destroy many different types of cancer cells, including breast cancers, whilst leaving normal cells unaffected," she said. Debilitating symptoms associated with conventional treatments...

... respectively). However, a sustained drop in deep body (core) temperature would be in direct conflict wit...ddling might rely on mechanisms other than a lower body temperature. To better understand this mechanism, the researchers conducted the first recording...

Performing surgery on a beating heart may be safer

... “However, this process frequently leads to ‘whole body inflammation,?which includes complications such as brain swelling, heart arrhythmia and infections.?According to Raja, performing the surgery on the beating heart, while more technically challenging for the surgeon, keeps these side effects low and a...

White blood cells of cancer-resistant mice overwhelm natural defenses of cancer cells

...s of the so-called innate immune system, which the body ordinarily employs to fight off bacteria, but which had not been thought to be effective in fighting off cancer. Instead, in these cancer-resistant mice, three white-blood-cell types of the innate immune system ?neutrophils, macrophages and natural k...

A potential biological cause for sudden infant death syndrome

...he brain that regulates breathing, blood pressure, body heat, and arousal ?in babies who died from SIDS. SIDS is the leading cause of death in American infants after the newborn period, affecting 0.67 in 1,000 live-born babies. Although epidemiologic studies have identified risk factors for SIDS, such ...

Stress hormones may play new role in speeding up cancer growth

... there, they can travel to another location in the body to form additional tumors, a process called metastasis. The research also suggests the same hormone can also stimulate the tumor cells to release another compound that can aid in the growth of new blood vessels that feed cancer cells, hastening th...

ASU researchers test antibacterial effects of healing clays

...munosuppressant; the patients feel no pain and the body mounts no response to infection. It leads to disfigurement, isolation, not unlike that seen in leprosy," Haydel explains. "Traditional antibiotics can only make a difference at the very earliest stages of the disease, so treatments have, in the past,...

New study aims to stop sepsis in its tracks

...ng widespread inflammation and dramatic changes in body temperature, blood pressure, breathing, and heart rate. It can lead to the malfunction or failure of several major organs. "The goal of this project is to speed recovery, increase survival rates, and improve the long-term quality of life for those ...

Living view in animals shows how cells decide to make proteins

... same genes found in every cell of an individual’s body can produce different proteins in different tissues and organs. These varied proteins, in turn, dictate the function of each tissue or organ. The findings also may offer insight into a number of diseases, including cancer, in which the genetic pro...

Mutant gene causes severe kidney disease in infants

Some types of nephrotic syndrome can be treated with steroids or other drugs, but steroid-resistant forms of the disease as a rule do not respond to trea...

Negative effects of caffeine are stronger on daytime sleep than on nocturnal sleep

...he signal from the biological clock that tells the body it should be awake at this time of day," explains Dr. Carrier. "We often use coffee and other sources of caffeine during the nighttime to counteract sleepiness generated by sleep deprivation, jet lag, and shift-work. However, this habit may have impo...
