Lymph nodes from patients with colorectal cancer were immunohistochemically stained for cytokeratin to investigate the relationship between the presence of occult neoplastic cells (ONCs) and recurrence/metastasis. A total of 80 patients with stage III/Dukes' C colorectal cancer were divided into 16 patients who developed recurrence/metastasis (recurrence group) and 64 patients without recurrenc...

the objective of the present investigation was to design a sustained release floating microcapsules of theophylline using two polymers of different permeability characteristics; eudragit rl 100 (eu rl) and cellulose acetate butyrate (cab) using the oil-in-oil emulsion solvent evaporation method. polymers were used separately and in combination to prepare different microcapsules. the effect of d...

Glutamate receptors on giant danio retinal on bipolar cells were studied with whole cell patch clamping using a slice preparation. Cone-driven on bipolars (Cbs) and mixed-input on bipolars (Mbs) were identified morphologically. Most Cbs responded to the excitatory amino acid transporter (EAAT) substrate d-aspartate but not to the group III metabotropic glutamate receptor (mGluR) agonist l-(+)-2...

In the present work, a study of thermoelastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient and non-uniform internal pressure is carried out. The formulation is based on first-order shear deformation theory (FSDT), which accounts for the transverse shear. The governing equations, derived using minimum total potential energy principle, are solved, usi...

How to improve the power generation of wave energy converters (WEC) has become one main research objectives in field. This paper illustrates a framework on use back propagation (BP) neural network predicting capture frustum cone shaped floating body. Mathematical model single body is derived, and radius, semi-vertical angle, mass, submergence depth, take-off (PTO) damping coefficient, stiffness...

By means of asymmetric color matching, the effects of steady-state chromatic adaptation on the color appearance of briefly presented chromatic flashes were investigated. The adapting and test lights were of equal luminance (35 cd/m2) and differed from the standard grey adapting light either along the L-2M (red and green), or along the S-(L+M) (yellow and violet) line. The red (green) adapting l...

The present investigation is concerned about the development of floating bioadhesive drug delivery system of venlafaxine hydrochloride which after oral administration exhibits a unique combination of floating and bioadhesion to prolong gastric residence time and increase drug bioavailability within the stomach. The floating bioadhesive tablets were prepared by the wet granulation method using d...

Age estimation from dental radiographs is a non-destructive method to obtain information. The purpose of this investigation was to evaluate the possibility of age estimation from root diameter and root canal diameter of maxillary central incisors radiographs. 420 cone-beam computed tomography images of maxillary central incisors (210 males and 210 females) aged 15 to 84 years were chosen and cl...

Abstract The influence of single and multiple imperfection cases on the load carrying capacity mild steel cone subjected to axial compression was considered through numerical simulation in current paper. Three different techniques were considered, which are: i) uneven length (sinusoidal/square waves), ii) crack, iii) indentation (SLI) imperfection. Abaqus 6.19 FE used carry out simulation. comp...

The representation of floating point numbers and the method of generating random floating point numbers can have a significant effect upon the performance of the simulated annealing algorithm. Finite precision may limit the minimum obtainable cost, may result in an optimal minimum temperature, and may imply an optimal chain length.
