SURGELLA: A Scoping Review of Impella‐Assisted Hemodynamic Support in High‐Risk Non‐Cardiac Surgery

Artificial Organs, EarlyView.
In selected patients with severe LV dysfunction, Impella‐supported non‐cardiac surgery may provide a temporary hemodynamic bridge to otherwise prohibitive procedures. Published evidence remains limited to a small number of highly selected cases, supporting technical feasibility rather than comparative benefit or generalizable safety.

Familial nonsyndromic pheochromocytoma.

, 2006
Judging from recent data, heritable forms account for 30-40% of pheochromocytomas. The molecular basis for the familial pheochromocytoma has been largely elucidated and the role of germline mutation of the VHL, RET, SDHB, and SDHD genes has been ...

Evidence That the Protein Phosphatase Activity of PTEN Contributes to Embryonic Development and Tumor Suppression

Cancer Science, EarlyView.
Mice expressing only mutant PTEN Y138L, a protein which shows normal suppression of cellular AKT yet lacks protein phosphatase activity, die in utero, and heterozygous mice display a range of tumors. This indicates both the lipid and protein phosphatase activities of PTEN work together for normal tumor suppression and embryonic development.

PHEOCHROMOCYTOMA

Survey of Anesthesiology, 1976
In the 25-year period 1950-1975 forty-four patients with pheochromocytoma were observed at Vanderbilt University Affiliated Hospitals. Bilateral adrenal tumors occurred in 3 patients (6.8%) and extra-adrenal tumors occurred in 7 others (16%), 33 patients (75%) had single tumors arising in one of the adrenal glands; in one of these 5 years after ...
