| modeling cardiac arrest and resuscitation in the domestic pig. | cardiac arrest remains a leading cause of death and permanent disability worldwide. although many victims are initially resuscitated, they often succumb to the extensive ischemia-reperfusion injury inflicted on the internal organs, especially the brain. cardiac arrest initiates a complex cellular injury cascade encompassing reactive oxygen and nitrogen species, ca(2+) overload, atp depletion, pro- and anti-apoptotic proteins, mitochondrial dysfunction, and neuronal glutamate excitotoxity, which ... | 2015 | 25685718 |
| mechanism by which shock wave lithotripsy can promote formation of human calcium phosphate stones. | human stone calcium phosphate (cap) content correlates with higher urine cap supersaturation (ss) and urine ph as well as with the number of shock wave lithotripsy (swl) treatments. swl does damage medullary collecting ducts and vasa recta, sites for urine ph regulation. we tested the hypothesis that swl raises urine ph and therefore cap ss, resulting in cap nucleation and tubular plugging. the left kidney (t) of nine farm pigs was treated with swl, and metabolic studies were performed using bil ... | 2015 | 25656372 |
| domestic pigs' (sus scrofa domestica) use of direct and indirect visual and auditory cues in an object choice task. | recently, foraging strategies have been linked to the ability to use indirect visual information. more selective feeders should express a higher aversion against losses compared to non-selective feeders and should therefore be more prone to avoid empty food locations. to extend these findings, in this study, we present a series of studies investigating the use of direct and indirect visual and auditory information by an omnivorous but selective feeder-the domestic pig. subjects had to choose bet ... | 2015 | 25650328 |
| sodium nitroprusside-enhanced cardiopulmonary resuscitation facilitates intra-arrest therapeutic hypothermia in a porcine model of prolonged ventricular fibrillation. | the aim of this study was to assess the effect of sodium nitroprusside-enhanced cardiopulmonary resuscitation on heat exchange during surface cooling. we hypothesized that sodium nitroprusside-enhanced cardiopulmonary resuscitation would decrease the time required to reach brain temperature less than 35°c compared to active compression-decompression plus impedance threshold device cardiopulmonary resuscitation alone, in the setting of intra-cardiopulmonary resuscitation cooling. we further hypot ... | 2015 | 25525755 |
