Geographic fatty liver is sometimes revealed on computed tomography (CT) images. In patients with this condition, perivascular fat deposition characterized by halos of fat surrounding the hepatic and/or portal vein develops; however, the pathogenesis remains unknown (1, 2). A 30-year-old man developed severe alcoholic hepatitis. Initial abdominal CT revealed homogeneous fatty liver with mild ma...

Purpose: The present study aimed to evaluate the effect of dominant lower limb on the correlation between some of the dynamic variables of ankle joint and center of mass during quiet standing balance control. Methods: Twelve healthy females with no known neurological or musculoskeletal disorders, with the mean age of 26±3.5 years, participated in this study. Motion analysis system, force ...

A computational approach for analyzing visible textures is described. Textures are modeled as irradiance patterns containing a limited range of spatial frequencies, where mutually distinct textures differ significantly in their dominant characterizing frequencies. By encoding images into multiple narrow spatial frequency and orientation channels, the slowly-varying channel envelopes (amplitude ...

We develop a wideband traveling-wave formalism for analyzing quantum mechanically a degenerate parametric amplifier. The formalism is based on spatial differential equations-spatial Langevin equations-that propagate temporal Fourier components of the field operators through the nonlinear medium. In addition to the parametric nonlinearity, the Langevin equations include absorption and associated...

Huntington disease is a neurodegenerative disorder transmitted as an autosomal dominant trait. It is the first neurological disease for which presymptomatic testing has been available for 20years in France. Follow-up of mutation carriers provided a better understanding of the presymptomatic phase of the disease and will change medical practice. Studying this phase led to the identification of c...

background: gender role attitudes toward sexual matters may define suitable and appropriate roles for men and women during a sexual relationship. this study aimed to explore and assess gender-based sexual roles in iranian families. materials and methods: this was an exploratory mixed methods study in which perceptions and experiences of 21 adult iranian participants about gender-based sexual ro...

the aim of this study was to compare the performance of analogy (implicit),explicit and discovery learning in the retention and transfer of a topspin shot underpsychological pressure. for this purpose, 36 volunteer high school students wererandomly allocated to three treatment conditions: explicit, analogy, and discoverylearning. after performing 300 trials in the acquisition phase, an immediat...
