micropapillary variant of urothelial carcinoma (uc) of the bladder is an aggressive tumour, comprising 0.6-6% of all uc. it generally presents with high-grade and stage, and has been reported as having a worse prognosis when compared to traditional uc. we report the case of a 58-year-old man who presented with macroscopic haematuria. the patient was diagnosed with high-grade urothelial carcinom...

background and aims: immunohistochemical tests are one of the most important tests, which are under study to determine the prognosis of the cancers such as transitional cell carcinoma. by the time, flexible cystoscopy and urine cytology are the routine tests for following up the patients with transitional cell carcinoma, which are both operator dependent. on the other hand, cystoscopy is an inv...

Summary In this study, the seismic performance of hexagrid structures which are composed of horizontal and vertical hexagrid by using a transitional story, has been investigated. To this end, 10 models of 50-story hexagrid structures were designed. 9 models with horizontal hexagrid cells which transited to vertical cells using a transitional story, and a model of completely horizontal hexagrid ...

background: the present study was undertaken to investigate the correlation of epidermal growth factor receptor (egfr) expression with grade of transitional cell carcinoma (tcc). methods: tumor samples of 75 patients from mostafa khomaini hospital with transitional cell carcinoma of the bladder were analyzed by immunohistochemistry for expression of egfr. in this context, we assigned the bladde...

the length and structure of the transitional zone in the tunica media in the renal artery of adult male cats were investigated. in addition, the volume of the lumen and different layers in transitional and nontransitional zones in the right and left sides were also determined. morphometrical, histological and stereological studies were performed on 16 renal arteries of 8 adult male cats. after ...

Ilex cornuta Lindl. & Paxton is a commercially important horticultural species worldwide, and extensive cultivation hybridization have produced many varieties. Despite the considerable breeding, selection, widespread domestication, which may significant role in composition of genomes, there are no other previous reports intraspecific genome size variation different cultivars or hybrids this...

introduction: previous studies have indicated a relationship between mptp pore and av nodal rate-dependent properties. the aim of present study was to determine acute direct effects of cyclosporine on extracellular field potential of isolated rabbit av node during experimental atrial fibrillation. methods: in one group of male new zealand rabbits (1.5-2.5 kg) cumulative concentrations of cyclos...

4990 bi-syllabic English words were syllabified by about 22 native speakers who choose between different slash divisions (e.g. photon: FOW/TAHN, FOWT/AHN). Results of the regression analyses of the items with one medial consonant are discussed. Consistent with previous studies, consonants were drawn to stressed syllables, and more sonorant consonants were more often placed in the coda. A model ...

a linear low density polyethylene (lldpe) production process, including two- fuidized bed reactors in series (fbrs) and other process equipment, was completely simulated by aspen polymer plus software. fluidized bed reactors were considered as continuous stirred tank reactors (cstr consisted of polymer and gas phases). poly-srk and nrtl-rk equations of state were used to describe polymer and no...
