The mode of natural killer (NK) cell migration to the sites of inflammation and transplanted tumors was investigated by using dry ice for physical irritation and 1-fluoro-2,4 dinitrobenzene (DNFB) for chemical irritation in mouse ear. In experiments with transplanted tumors, NK cell sensitive tumor cells (RL male 1) and insensitive tumor cells (p815) were transplanted into the ears of C3H and B...

BACKGROUND AND PURPOSE Circulating blood cells have been implicated in the pathogenesis of cerebral ischemia/reperfusion (I/R) injury and stroke. The objective of this study was to define the magnitude and molecular determinants of the platelet- and leukocyte-endothelial cell adhesive interactions induced by I/R in the mouse brain. METHODS Bilateral common carotid artery occlusion was induced...

Transient administration of ANG II causes persistent salt-sensitive hypertension associated with arteriolopathy, interstitial inflammation, and cortical vasoconstriction; blocking the vascular and inflammatory changes with mycophenolate mofetil (MMF) prevents vasoconstriction. While infiltrating leukocytes during the salt-sensitive hypertension phase express ANG II, the functional role of ANG I...

OBJECTIVE Apparent diffusion coefficient (ADC) values calculated through magnetic resonance imaging have been proposed as a useful tool to distinguish benign from malignant liver lesions. Most studies however included simple cysts in their analysis. Liver cysts are easy to diagnose, have very high ADC values and their inclusion facilitates differentiation in the ADC values between benign and ma...

Glaucomatous optic nerve damage is associated with alterations of the intra- and parapapillary optic disc area. We measured and compared the parapapillary region in 582 eyes of 321 patients suffering from chronic primary open-angle glaucoma and in 390 eyes of 231 normal subjects. Only one randomly assessed eye per patient and subject was taken for statistical analysis. Highly mopic eyes with a ...

This study quantitatively assessed the periapical bone repair following endodontic surgery, using planimetric evaluation based on two- (conventional and digital intraoral radiographic images - IRs) and three-dimensional (cone beam computed tomography - CBCT) evaluation. Eleven maxillary anterior teeth (of 11 patients) with periapical bone lesions and indication for surgical endodontic treatment...

conclusions adc valuecould be a prognostic factor to monitor the response to therapy for patients with cervical cancer. the addition of dw-mri to the conventional mri protocolsconsiderably improved the diagnostic ability of mr imaging method for tumor evaluations. results studies had shown thatthe mean adc value of cervical carcinoma (1.110 ± 0.175 × 10-3 mm2/s)is significantly lower than that ...

the goal is assessing the diffusion magnetic resonance imaging (dmri) method effi ciency in characterizing focal hepatic lesions (fhls). about 28-fhl patients were studied in radiology and clinical imaging department of our university hospital using 1.5 tesla mri system between january 2010 and june 2011. patients underwent hepatic mri consisting of dynamic t1- and t2-weighted imaging. the dmri...

this study evaluated the effects of end to end joint types of athel stripes at three level (end to end basic, end to end mitrated and end to end half lap joint) used in core layer veneered with three wood species (fir, beech and oak) and glued with three different ratio of melamine formaldehyde/urea formaldehyde resin (0:100, 25:75 and 50:50) on the bending strengths of bloakboard. according to...
