RCC - 5 and its

چکیده

We investigate the computational properties of the spatial algebra RCC-5 which is a restricted version of the RCC framework. The satis-ability problem for RCC-5 is known to be NP-complete but not much is known about its approximately four billion subclasses. We provide a complete classiication of satissability for all these subclasses into polynomial and NP-complete respectively. In the process, we identify all maximal tractable subalgebras which are four in total.

Dyspnea as the First Manifestation of Silent Renal Cell Carcinoma

Renal cell carcinoma (RCC) accounts for only 3% of adult malignancies, and the lung is the most common site of metastasis of this tumor, which may be accompanied by pleural metastasis. However, solitary pleural involvement is very rare and its presentation with dyspnea as the first manifestation of RCC is extremely rare.We describe a 39-year-old male with episodes of dyspnea dating back 6...

Expression Of P53 And Ki67 Proteins In Renal Cell Carcinoma And Its Relationship With Nuclear Grade

Background and Objective: Evaluation of tumor proliferative activity may provide a predicting parameter to estimate biologic aggression and a subsequent prognosis that has been evaluated in many malignancies. We have selected renal cell carcinoma (RCC) in this study. To determine tumor proliferative activity, KI67 antibody was applied and results were compared with apoptosis, applying P53 antib...
