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...

Serial sections of mouse foetal liver, during the 9th and 16th days of gestation, were studied. The erythropoietic process starts in the central area of the growing hepatic lobes, and subsequently spreads towards the periphery. Each lobe passes successfully through an undifferentiated, proliferating and differentiating period, but does not proliferate and differentiate in a homogeneously synchr...

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...

BACKGROUND AND OBJECTIVES Despite the move toward integrated 4-year medical school curricula, many medical schools still offer a "2+2" curriculum divided into preclinical and clinical phases. These phases represent distinct learning environments that require different learning skills. To prepare students for learning in the clinical environment of the second 2 years, many medical schools offer ...

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 ...

Some important discrepancies in weather forecast for urban area during frontal zones’ transitional periods are constantly observed, when air pollution is combined with electromagnetic smog. Often the days’ lasting phenomenon is due to an unstable phase in humidity transition, which is generated by electromagnetic smog stimulation of anthropogenic aerosol aggregation. This result is a fog-like c...

The stages of development leading up to the formation of mature B-1 cells have not been identified. As a result, there is no basis for understanding why various genetic defects, and those in the classical or alternative NF-κB pathways in particular, differentially affect the B-1 and B-2 B cell lineages. In this article, we demonstrate that B-1 B cells are generated from transitional cell interm...

In a longitudinal study, five indicators of a transition in the development of analogical reasoning were examined in young elementary school children, (a) bimodality and (b) inaccessibility in the frequency distributions of test performance, and in the responses of the transitional subjects, respectively, (c) sudden jumps, (d) anomalous variance, and (e) critical slowing down. An open-ended geo...
