BACKGROUND Clinical and pathological parameters may overestimate the need for chemotherapy in patients with early-stage breast cancer. More accurate determination of the risk of distant recurrence is now possible with use of genetic tests, such as the 70-gene MammaPrint profile. OBJECTIVES A health technology assessment performed by a medical insurer in 2009 introduced a set of test eligibili...

plants are rich source of phenolic compounds (phenolic acids, flavonoids and tannins) that are most important natural antioxidants. in the present study two ultrasonic methods including probe and bath were used for the extraction of phenolic and flavonoid compounds from celtis australis. the effects of different extraction time including 30, 60 and 90 min (bath method) and 5, 10 and 20 min (pro...

A factor, cornin, inhibiting the growth of L cells cultured in monolayer was extracted from bovine liver with boiling water and was partially purified by gel filtration with Sephadex G-200. The factor was (1) precipitable with ethanol at the concentration between 70% and 90%, (2) impermeable through dializing memo brane, (3) eluted as the last peak at the gel filtration and (4) containing prote...
