Evaluation of transcutaneous CO2 responses following acute changes in PaCO2 in healthy subjects.

14 Dec 2009 BACKGROUND AND OBJECTIVE: Transcutaneous blood gas-monitoring systems with miniaturized SpO(2) (peripheral blood oxygen saturation)/PCO(2) combined sensors (TOSCATM) have been widely used. There are no reports of the inter- and intra-individual ... Read more...

Impairment of intracerebral arteriole dilation responses after subarachnoid hemorrhage. Laboratory investigation.

30 Oct 2009 OBJECT: Cerebrovascular dysfunction after subarachnoid hemorrhage (SAH) may contribute to ischemia, but little is known about the contribution of intracerebral arterioles. In this study, the authors tested the hypothesis that SAH inhibits the ... Read more...

Radiotherapy in conjunction with 7-hydroxystaurosporine: a multimodal approach with tumor pO2 as a potential marker of therapeutic response.

30 Oct 2009 Checkpoint inhibitors potentially could be used to enhance cell killing by DNA-targeted therapeutic modalities such as radiotherapy. UCN-01 (7-hydroxystaurosporine) inhibits S and G2 checkpoint arrest in the cells of various malignant cell lines and ... Read more...
