Is detection of disseminated tumor cells in liver biopsies of colorectal cancer patients associated with a worse prognosis?
This study demonstrates that detection of disseminated tumor cells in liver samples from patients with UICC stage I-III colorectal cancer has no prognostic influence. UICC classification was the strongest prognostic factor in this patient series.
In our 24-h mouse model of sepsis, NO in skeletal muscle is primarily derived from nNOS. Sepsis impairs both EDRF- and EDHF-mediated dilation in response to ACh. Both genetic deletion and inhibition of nNOS protect against this impairment when the dilation occurs via the EDRF but not EDHF pathway.
