Background: Previous research has shown that experiencing motion stimuli negatively impacts cognitive performance.

Objective: In the current study, we investigate whether this impact relates to Type-II spatial disorientation (SD), to motion stimulus magnitude, or to an interaction of these factors.

Method: Stimuli for participants ( = 23) consisted of Earth-vertical yaw rotations on a rotating chair in a completely darkened room.

Purpose: To evaluate the therapeutic outcome of radical cystectomy and radical radiotherapy in patients with T2N0M0 clinical stage bladder cancer in relation to their age.

Patients And Methods: Between 1995-2006, 119 patients with clinical stage T2N0M0 bladder cancer were treated with radical radiotherapy (group A) and were divided in 2 subgroups: >70 years old (A1) and 70 years old/B1 subgroup and View Article and Find Full Text PDF

Objective: We investigated the expression of thymidine phosphorylase (TP) in bladder carcinomas and assessed its prognostic significance in superficial bladder cancer samples.

Patients And Methods: We studied 142 primary bladder cancer samples immunohistochemically for nuclear thymidine phosphorylase (TPN), cytoplasmic (TPC) and stromal (TPSTR) expression. We correlated them with standard clinicopathological features (grade, stage, concurrent in situ, multiplicity, primary or recurrent status), as well with recurrence and progression.

Objective: To assess the prognostic significance of angiogenesis parameters such as microvessel density (MVD) and vascular endothelial growth factor (VEGF) in superficial bladder cancer.

Patients And Methods: We studied 127 superficial bladder cancer samples immunohistochemically for the above factors. We compared them with standard clinicopathological features (grade, stage, concurrent in situ, multifocality, primary or recurrent status) as well as with p53 expression, recurrence and progression to muscle infiltrating disease.
