To obtain the correlation between morphologic features in the invasive fronts of colorectal cancer (CRC) and L1 cell adhesion molecule (L1CAM) expression, 275 CRCs were assessed with L1CAM immunostaining and 29 CRCs were examined for L1CAM messenger RNA (mRNA) expression. Based on immunostaining, the positive rate of L1CAM expression increased according to the grade of tumor budding (P = .0002)...

kuhbanan fault system, as one of the intracontinental faults of central iran, is recognized by considerable seismogenic activities and modern morphotectonics evidences with a strike-slip (reverse component) motion. according to the geometric and kinematics data, kuhbanan fault has been divided into 5 segments (s26, s27, s28, s29, s30) in bahabad region. measured geomorphic indices of ratio of v...

Channelization has changed the form and dynamics of rivers on a global scale. In midwestern United States, widespread straightening meandering headwater streams been undertaken for purpose improving land drainage. Few studies have examined in detail how respond to straightening, especially over timescales nearly century following straightening. This study uses historical aerial imagery contempo...

Abstract River channels are among the most common landscape features on Earth. An essential characteristic of is sinuosity: their tendency to take a circuitous path, which quantified as along-stream length divided by straight-line length. sinuosity interpreted that either forms randomly at channel inception or develops over time meander bends migrate. Studies tend assume latter and thus have us...

Stem sinuosity is a highly visible stem-form trait in the leaders of fast-growing Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) trees, yet its cause is unknown. We tested the hypotheses that sinuous stems have longer expanses of primary growth than nonsinuous stems (putting the leader at higher risk for curvature, induction of compression wood formation, and possibly overcor...

Southern elephant seals, Mirounga leonina, undertake large-scale oceanic movements to access favourable foraging areas. Successful foraging areas of elephant seals from the Kerguelen Islands are investigated here in relation to oceanographic parameters. Movements and diving activity of the seals as well as oceanographic data were collected through a new generation of satellite relayed devices m...

Axisymmetric toroidal wave fronts are pertinent to the near forward and backward scattering by objects that have rotational symmetry. For spheres, the wave field produced by such a wave front is known as glory scattering. As the wave front propagates, ome porton of it becomes focused on an axis, forming a structurally unstable line caustic. A specific lass of harmonic perturbations of the wave ...
