A new measuring procedure can help to investigate in some detail the behavior of magnetic nanoparticles which are used for cancer therapy.

The interaction of sex, age and ethnicity has a significant impact on overall survival in metastatic colorectal cancer patients, a new study suggests. Researchers found that pre-menopausal women with metastatic colorectal cancer (18-44 years old) lived longer than younger men, while older women (75 and older) had significantly worse overall survival than older men.

Previous studies have shown how polycyclic aromatic hydrocarbons damage DNA, with the emphasis on how PAHs bind directly to DNA itself, leading to the mutations in critical genes that cause disease. Now, researchers have shown that PAHs, via oxidative stress, can also led to mutations in critical genes important in lung cancer.

A new non-invasive method has shown success in detecting and measuring non-calcified plaque, a buildup of soft deposits embedded deep within the walls of the heart's arteries, undetectable by angiography or cardiac stress tests -- and prone to rupture without warning.

During menopause, lack of estrogens increases the risk of suffering cardiovascular diseases. Menopause is a natural period in the aging process of a woman. On ceasing the ovary function, the body gradually stops producing eggs and female sex hormones (amongst these being estrogen and progesterone), responsible for regulating the menstrual cycle. Lack of estrogens increases the risk of very important diseases with respect to premenopause, amongst these being osteoporosis and illnesses related to the cardiovascular system.

Tobacco smokers who eat three servings of fruits and vegetables per day and drink green or black tea may be protecting themselves from lung cancer, according to a first-of-its-kind study by cancer researchers. The study is the first to find that plant components called flavonoids may prevent the disease.

Cough and cold medication use in young children has been linked to a significant number of adverse effects and several deaths. Despite these concerns about safety and efficacy, there has been little research on patterns of cough and cold medication use in very young children. Now, a new study from reveals important new statistics about medication use in children under the age of two.

According to some experts, newly born neuronal stem cells in the adult brain may provide a therapy for brain injury. But if these stem cells are to be utilized in this way, the process by which they are created, neurogenesis, must be regulated.

New genetic mutations responsible for impaired fetal movement, which leads to a multitude or problems in later life as well as early spontaneous abortion, have been identified.

A new study found a strong connection between the cognitive function of their elderly study participants and their postural stability -- or balance. In the study, a questionnaire designed to probe cognitive function proved effective at identifying people with poorer balance.
