CO2-formatics: how do proteins bind carbon dioxide?

The rising atmospheric concentration of CO(2) has motivated researchers to seek routes for improved utilization, increased mitigation, and enhanced sequestration of this greenhouse gas. Through a combination of bioinformatics, molecular modeling, and first-principles quantum mechanics the binding of carbon dioxide to proteins is analyzed. It is concluded that acid/base interactions are the principal chemical force by which CO(2) is bound inside proteins.

Palliative care needs of cancer patients in U.S. nursing homes.

Background: Increasingly, nursing homes are the place of care for older Americans with cancer. Yet, few studies has characterized the quality of care for this growing population.

Objective: Characterize the scope and quality of cancer care in U.

Acute right atrial strain: regression in normal as well as abnormal P-wave amplitudes with treatment of obstructive pulmonary disease.

Objective: To evaluate right atrial (RA) "strain" as reflected by changes in P-wave amplitude and vector in patients with COPD immediately before and immediately after beginning treatment of exacerbations.

Background: P-pulmonale (frequently temporary, reflecting acute RA strain) occurs under a variety of circumstances, including COPD. Emergency room (ED) ECGs in patients with acute exacerbations of COPD have suggested that P-pulmonale (P waves > or = 2.
