In quiescent rat ventricular myocardium, bathed in solution of 2 mM Ca++ or less, it has been previously demonstrated that spontaneous microscopic oscillatory cell motion is present and interacts with an incident laser beam to produce scattered light intensity fluctuations which can be monitored to quantify the underlying motion. The present study shows that scattered light intensity fluctuatio...

An experimental set-up of the method of caustics was proposed for the accurate evaluation of stress intensity factor. The stress intensity factor evaluation was based on a new formula which was based on the caustic shape area. The new formula was based on the shape area of the caustics. The stress optical constants were evaluated according to the new formula of the stress intensity factor. The ...

In this study, we investigated 30 cases of dysplastic lesions and bladder carcinomas. The lesions presented different degree of differentiation and depth of invasion. The aim of this study was to appreciate the immunoexpression of some proteins, like E-cadherin and p63, which are implicated in the cellular adhesiveness and the normal development of the urothelium, depending on the degree of tum...

This study examines the intensity change and moat dynamics of typhoons with concentric eyewalls using passive microwave data and best-track data in the western North Pacific between 1997 and 2006. Of the 225 typhoons examined, 55 typhoons and 62 cases with concentric eyewalls have been identified. The data indicate that approximately 57% of category 4 and 72% of category 5 typhoons possessed co...

Integration of shape prior information into level set formulations has led to great improvements in image segmentation in the presence of missing information, occlusion, and noise. However, most shape-based segmentation techniques incorporate image intensity through simplistic data terms. A common underlying assumption of such data terms is that the foreground and the background regions in the ...

In its photosensory effect, the action of light depends on two variables,-intensity and time. If the intensity alone is varied, the photochemical effect is proportional to the logarithm of the intensity. If the time alone is varied, the effect is proportional to the time. Experiments here reported show that when both the intensity and the time are varied, the photochemical effect is equal to th...

this study was undertaken to determine the prevalence and diversity of eimeria species in sheep in tabriz suburb. the prevalence of ovine parasitism due to eimeria spp. was estimated in 240 sheep aged less than six months to over 12 months, in a period of one year (2003-2004). the samples were collected from pre-slaughtered sheep in tabriz slaughterhouse and transferred to the parasitology labo...

Objective: Renal failure is a complication of diabetes. It can be the risk factor of cardiovascular disease. This study aimed to evaluate the effect of exercise course and Aloe-Vera supplementation on renal function and lipid profile in type 2 diabetes mellitus (T2DM) patients. Materials and Methods: This is a clinical trial double blind with pre-test and post hoc test analyses with a control ...

A non-rigid ultrasound image registration method is proposed in this work using the intensity as well as the local phase information under a variational framework. One application of this technique is to register two consecutive images in an ultrasound image sequence. Although intensity is the most widely used This research was partially supported by the Ministry of Knowledge Economy, Korea, un...

Introduction: A problem posed by electrical field (E) stimulation of biological preparations with high excitation threshold is that the E intensity required for excitation is likely to induce water electrolysis at the electrode surface, which can alter the extracellular medium and cause deleterious effects on the cells. In this study, different electrode materials and geometries were tested aim...
