Inhaled, nebulized sodium nitrite protects in murine and porcine experimental models of hemorrhagic shock and resuscitation by limiting mitochondrial injury.

Objective: The cellular injury that occurs in the setting of hemorrhagic shock and resuscitation (HS/R) affects all tissue types and can drive altered inflammatory responses. Resuscitative adjuncts hold the promise of decreasing such injury. Here we test the hypothesis that sodium nitrite (NaNO2), delivered as a nebulized solution via an inhalational route, protects against injury and inflammation from HS/R.

Carbon monoxide protects against hemorrhagic shock and resuscitation-induced microcirculatory injury and tissue injury.

Unlabelled: Traumatic injury is a significant cause of morbidity and mortality worldwide. Microcirculatory activation and injury from hemorrhage contribute to organ injury. Many adaptive responses occur within the microcirculatory beds to limit injury including upregulation of heme oxygenase (HO) enzymes, the rate-limiting enzymes in the breakdown of heme to carbon monoxide (CO), iron, and biliverdin.

A novel technology to screen for cognitive impairment in the elderly.

Background: Traditional evaluation of mild cognitive impairment (MCI) can be costly, time consuming, and impractical for widespread screening. DETECT is a portable device developed to rapidly perform cognitive testing in diverse settings. This study compares DETECT with formal clinical assessment.

Fixed volume or fixed pressure: a murine model of hemorrhagic shock.

It is common knowledge that severe blood loss and traumatic injury can lead to a cascade of detrimental signaling events often resulting in mortality. These signaling events can also lead to sepsis and/or multiple organ dysfunction (MOD). It is critical then to investigate the causes of suppressed immune function and detrimental signaling cascades in order to develop more effective ways to help patients who suffer from traumatic injuries.
