With their consent, patients' tumour samples were analysed for KRAS/BRAF oncogene mutation status and topoisomerase 1 (topo-1) immunohistochemistry. Patients were then classified into one of four molecular strata; within each strata patients were randomised to one of two hypothesis-driven experimental therapies or a common control arm (FOLFIRI chemotherapy).
Establishing the ages of strata within a region, as well as the ages of strata in other regions and on different continents, involves stratigraphic correlation from place to place.
The GSSP marker, located in an unused quarry bordering the Cefn-Cerig Road near Llandovery, is placed just above the highest strata within which the brachiopod Eocoelia intermedia appears and below the strata recording the emergence of E. curtisi.
Are there distinct social strata within this one apartment building?
The dominant, integrated companies were displaced by specialists that competed in horizontal strata within the value chain.
We observed differences in grain size fractions between strata within and between reaches.
The retina extracts about a dozen different abstractions, formed at different strata within the retina, and transmitted separately along the optic nerve.
Mid-Cretaceous strata within the Tintina Trench, 3 km west of the community of Ross River, contain evidence of deposition in two distinct, alternating, fluvial settings.
We collected and analyzed bottom sediments to assess whether substrate composition, organic matter composition, and contaminant concentrations and detections varied among strata within and between the reaches.
Subsequently, however, surface uplift of the intermontane basin involved strata within the AB and resulted in the deposition of coarser sediments of the San Felipe Formation (Figs 1 and 2 35.
Correlation of Silurian strata within limits more refined than a stage (or its corresponding age) traditionally is achieved through the recovery of fossils belonging to shaley and shelly facies.
