Introduction: Gastric carcinoma is the second most common tumor in the world. Highest incidence is found in Japan, Chile and Italy. In tumor progression model of intestinal type of gastric carcinoma, the cellular changes progress from initial inflammation and chronic gastritis to metaplasia, dysplasia and adenocarcinoma. Distinguishing regenerative atypia from dysplasia and carcinoma is the mos...

In this note we investigate some matroid minor structure results. In particular, we present sufficient conditions, in terms of triangles, for a matroid to have either U2,4 or F7 or M(K5) as a minor.

Twelve patients with aortic stenosis (gradient 62 (25) mm Hg), and six normal subjects were examined using M mode echocardiography before and during submaximal bicycle exercise. Normal subjects showed a progressive fall in the end systolic minor axis dimension of the left ventricle and a rise in end diastolic dimension, giving an increase in stroke dimension and shortening fraction of 45% and 3...

The star formation histories of four fields within the Local Group dwarf irregular galaxy NGC 6822 are presented. Each of the fields was imaged by the WFPC2 aboard the Hubble Space Telescope and were used to obtain V I color-magnitude diagrams for each field reaching V ≃ 26. The magnitude of the tip of the red giant branch and the red clump were used to determine distances to NGC 6822 that are ...

We present evidence for the presence of a low-amplitude kinematically distinct component in the giant early-type galaxy M 87, via datasets obtained with the SAURON and MUSE integralfield spectroscopic units. The MUSE velocity field reveals a strong twist of ∼ 140 within the central 30 connecting outwards such a kinematically distinct core to a prolate-like rotation around the large-scale photom...

ABSTRACT We investigate whether the dust content of circum-galactic medium (CGM) depends on location quasar sightline with respect to galaxy major-axis using 13 galaxy-Mg ii absorber pairs (9–81 kpc distance) from MusE GAs FLOw and Wind (MEGAFLOW) survey at 0.4 < z 1.4. The CGM is obtained [Zn/Fe] ultraviolet visual echelle spectrograph data. When a direct measurement unavailable, we est...

Two-dimensional homonuclear NMR was used to characterize synthetic DNA minor groove-binding ligands in complexes with oligonucleotides containing three different A-T binding sites. The three ligands studied have a C(2) axis of symmetry and have the same general structural motif of a central para-substituted benzene ring flanked by two meta-substituted rings, giving the molecules a crescent shap...

The problem of a uniform transverse flow past a prolate spheroid of arbitrary aspect ratio a t low Reynolds numbers has been analysed by the method of matched asymptotic expansions. The solution is found to depend on two Reynolds numbers, one based on the semi-minor axis b, Rb = Ublv, and the other on the semi-major axis a, Ra = Ualv (U being the free-stream velocity at infinity, which is perpe...
