Implementing Cardiac Surgical Unit-Advanced Life Support Through Simulation-Based Learning: A Quality Improvement Project.

Background: The European Association for Cardio Thoracic Surgery and the Society of Thoracic Surgeons endorse Cardiac Surgical Unit-Advanced Life Support, a protocol designed specifically for cardiothoracic surgical patients who suffer postoperative cardiac arrests. To enhance patient outcomes and to reduce death rates, cardiothoracic intensive care unit nurses must be able to perform the protocol with confidence, proficiency, and without delays. To this end, simulation-based learning (SBL) is a pedagogical method ideal for optimized learning.

Peripheral and central sensitization in fibromyalgia: pathogenetic role.

Characteristic symptoms of fibromyalgia syndrome include widespread pain, fatigue, sleep abnormalities, and distress. Patients with fibromyalgia show psychophysical evidence of mechanical, thermal, and electrical hyperalgesia. Peripheral and central abnormalities of nociception have been described in fibromyalgia.

Characterization and targeted disruption of murine Nup50, a p27(Kip1)-interacting component of the nuclear pore complex.

p27(Kip1) is a member of the Cip-Kip family of cyclin-dependent kinase (Cdk) inhibitors that binds to cyclin-Cdk complexes and inhibits their catalytic activity in response to antiproliferative stimuli. p27(Kip1) is regulated by several posttranscriptional mechanisms, including subcellular localization. We have identified a component of the nuclear pore complex (NPC), termed Nup50, through its two-hybrid interactions with p27(Kip1).

Proteasomal turnover of p21Cip1 does not require p21Cip1 ubiquitination.

The Cdk inhibitor p21Cip1 is an unstable protein. Pharmacologic inhibition of the proteasome increases the half-life of p21 from less than 30 min to more than 2 hr and results in the accumulation of p21-ubiquitin conjugates. To determine whether ubiquitination was required for proteasomal degradation of p21, we constructed mutant versions of p21 that were not ubiquitinated in vivo.
