While cancer cases are rising at an alarming rate every year, early detection of the cancers is still a relatively difficult phenomenon. In fact, much of the morbidity and mortality in human cancer is related to the late diagnosis of this disease, where surgical and pharmacologic therapies are less effective. A recent study conducted at the Johns Hopkins Kimmel Cancer Center, reported a test that uses small amounts of cancer specific DNA in blood to detect early stage cancers.
Walnuts, packed with nutrients were found to be linked to promote better health and also promote feelings of fullness, thereby discouraging overeating and craving. In a new brain imaging study, consuming walnuts activated an area in the brain that is linked to regulating hunger and cravings, reveal the research team of Beth Israel Deaconess Medical Center (BIDMC).
Since Zika virus disease usually manifests in an asymptomatic manner, the detection becomes difficult. Moreover, Zika virus infection in pregnant women can cause fatal brain conditions in infants and other nerve damaging diseases in adults. This calls for Zika virus screening in endemic regions. However, the expense, time taken to obtain results and lower accessibility to testing laboratories limit early detection of the virus. A study conducted at the Washington University has reported a novel paper-based detection method that uses nano-particles.
