| species-specific variation in rela underlies differences in nf-?b activity: a potential role in african swine fever pathogenesis. | african swine fever virus (asfv) is a highly infectious disease of domestic pigs, with virulent isolates causing a rapidly fatal hemorrhagic fever. in contrast, the porcine species endogenous to africa tolerate infection. the ability of the virus to persist in one host while killing another genetically related host implies that disease severity may be, in part, modulated by host genetic variation. to complement transcription profiling approaches to identify the underlying genetic variation in th ... | 2011 | 21450812 |
| quantitative computed tomography in porcine lung injury with variable versus conventional ventilation: recruitment and surfactant replacement. | biologically variable ventilation improves lung function in acute respiratory distress models. if enhanced recruitment is responsible for these results, then biologically variable ventilation might promote distribution of exogenous surfactant to nonaerated areas. our objectives were to confirm model predictions of enhanced recruitment with biologically variable ventilation using computed tomography and to determine whether surfactant replacement with biologically variable ventilation provides ad ... | 2011 | 21460711 |
