BACKGROUND Hepatocellular carcinoma is a primary tumor of the liver and involves different treatment modalities according to the tumor stage. After local therapies, the tumor evaluation is based on the mRECIST criteria, which involves the measurement of the maximum diameter of the viable lesion. This paper describes a computed methodology to measure through the contrasted area of the lesions th...

The foraminifer Spiculosiphon oceana sp. nov. is a giant (>4 cm) agglutinated astrorhizid, which makes the second known species of this unusual genus and its first Mediterranean record. It has a peculiar stalked, capitate, monothalamous test. Bleach digestion and X-ray microanalysis indicated the test to be made exclusively of siliceous sponge spicules agglutinated in organic cement. The organi...

Contrast-enhanced magnetic resonance imaging (MRI) characteristics of small-diameter mass-forming intrahepatic cholangiocarcinomas (ICCs) (diameter ≤3 cm) are still unclear.This study focused on imaging findings of small mass-forming ICCs. The MRI findings for small-diameter mass-forming ICCs were summarized, and the enhancement features of small ICC nodules with different diameters [2 groups w...

The surface material at the Surveyor 5 site is granular and slightly cohesive. Spacecraft footpads plowed trenches in this material as the spacecraft slid during landing. For a compressible soil model, a static bearing capacity of 2.7 newtons/cm •' gave best agreement with the observations. Static firing of the vernier engines against the surface moved surface particles; a crater 20 cm in diame...

Partial least squares (PLS) modeling was utilized for the interpretation of the ultraviolet resonance Raman (UVRR) spectra of various lignin model compounds. Lignin model compounds presented different structural characteristics of the naturally existing lignin biopolymer within wood materials. The model compounds were grouped according to their monomer type, condensed and conjugated structures....
