Introduction:In this study, a non-invasive method based on consecutive ultrasonic image processing is introduced to assess time rate changes of the carotid artery wall displacement, velocity and acceleration in the longitudinal direction. The application of these parameters to discriminate healthy and atherosclerotic arteries was evaluated. Methods:Longitudinal displacement rate of common ...

The exact relationship between ultrasonograms and histological findings of the pancreas was investigated in 24 postmortem materials consisting of II cases of normal pancreas, 9 of pancreatic tumor and 4 of chronic pancreatitis, Normal pancreas showed a smooth contour and a homogeneous echo pattern with uniform echo intensity which was 10 dB higher than that of the normal liver. Pancreatic tumor...

We introduce consecutive-pattern-avoiding stack-sorting maps SC?, which are natural generalizations of West's map s and analogues the classical-pattern-avoiding s? recently introduced by Cerbai, Claesson, Ferrari. characterize patterns ? such that Sort(SC?), set permutations sortable via s?SC?, is a permutation class, we enumerate sets Sort(SC?) for ??{123,132,321}. also study SC? from dynamica...

Previous research demonstrated a relationship between the temporal pattern of heterosexual activity and an index of ovarian functioning. In the current study, this relationship was investigated in 147 menstruating heterosexual women (aged 19-53). They kept prospective daily records of menses, basal body temperature, sexual activity, and other behaviors for three consecutive menstrual cycles. In...

Herein the case of a 10-month-old boy with metachromatic leukodystrophy is reported. Diffusion MR imaging performed with an echo-planar trace sequence revealed a cytotoxic edema-like pattern (high signal intensity on b = 1000 s/mm(2) images and low apparent diffusion coefficient values) in the affected white matter in the absence of an ischemic condition. This finding was unchanged at a 6-month...
