Systemic treatment options in bladder cancer

Cancer Research, Statistics, and Treatment, 2018
Since the 1980's, with the advent of MVAC (methotrexate, cisplatin, vinblastine, adriamycin) the role of chemotherapy for bladder cancer was defined. Since then, multiple chemotherapy regimens have been used and the field of chemotherapy has reached a ...

Control of cell state transitions

Nature, 2022
Understanding cell state transitions and purposefully controlling them is a longstanding challenge in biology. Here we present cell state transition assessment and regulation (cSTAR), an approach for mapping cell states, modelling transitions between them and predicting targeted interventions to convert cell fate decisions.

Diffusion weighted imaging in the detection of upper urinary tract urothelial tumors

International Brazilian Journal of Urology, 2010
PURPOSE: Diffusion-weighted (DW) magnetic resonance imaging (MRI) provides information about the biophysical properties of tissues such as cell organization and density. DW imaging (DWI) is becoming important in the assessment of malignant tumors.
