Introduction: The current study investigated the combination of high Z atoms (iodine-, platinium-based drugs) with using low energy irradiation (120kvp) in Anaplastic Thyroid cancer cells.Materials and Methods: For this purpose, eight groups were designed: control (CNT), different concentrations of Iodine contrast media (ICM),  irradiation with various doses, Cis-platin (CDDP) with different c...

Speckle-tracking echocardiography (STE) uses a two-dimensional echocardiographic image to estimate two orthogonal strain components. The aim of this study was to assess sensitivity of circumferential (S(circ)) and radial (S(rad)) strains to infarct-induced left ventricular (LV) remodeling and scarring of the LV in a rat. To assess the relationship among S(circ), S(rad), and scar size, two-dimen...

Two-dimensional (2-D) speckle tracking echocardiography (STE) accurately quantifies circumferential strain (S(circ)) and radial strain (S(rad)) in humans and in large and small animals. This study was performed to assess sensitivity of S(circ) and S(rad) to left ventricular (LV) dysfunction in mouse models. We performed 2-D and M-mode echocardiography 1) in 6 mice during superficial and profoun...

This document discusses a numerical analysis method for low thrust trajectory propagation known as the proximity quotient or Q-Law. The process uses a Lyapunov feedback control law developed by Petropoulos [1] to propagate trajectories of spacecraft by minimizing the user defined function at the target orbit. A simplified propagator is created from the core mechanics of this method in MATLAB an...

OBJECTIVE This study is to investigate the immunostimulatory activities of dendritic cells (DCs) transfected with HBcAg and/or HBsAg recombinant adenovirus (rAd). METHODS DCs were transfected with rAd (DC/Ad-C+Ad-S, DC/Ad-C, and DC/Ad-S), or pulsed with HBcAg antigen (DC/HBcAg). Flow cytometry was used to detect the phenotype of DCs and the cytokine production of T lymphocytes. Mice were vacc...

The micromechanical properties of spider air flow hair sensilla (trichobothria) were characterized with nanometre resolution using surface force spectroscopy (SFS) under conditions of different constant deflection angular velocities theta (rad s(-1)) for hairs 900-950 microm long prior to shortening for measurement purposes. In the range of angular velocities examined (4 x 10(-4) - 2.6 x 10(-1)...

PURPOSE To examine the changes in performance of active plantar flexor muscles of rats by controlled dorsiflexion (i.e., stretching of muscles) at two angular velocities. METHODS Repeated stretches (30) at two velocities of ankle rotation [slow stretch (0.87 rads x s(-1) (i.e., 50 degrees x (s-1))), fast stretch (10.47 rad x s(-1) (i.e., 600 degrees x s-1))] were superimposed on maximally act...

Let G be a connected graph of order p and let 0 ::f. s ~ V ( G). Then S is a rad(G)-forcing set (or a radius-forcing set of G) if, for each v E V(G), there exists v' E S with dc(v, v') ?: rad(G). The cardinality of a smallest radius-forcing set of G is called the radius-forcing number of G and is denoted by rf(G). A graph G is called a randomly k-forcing graph for a positive integer k if every ...
