does pressure matter in creating burns in a porcine model?multiple animal models of burn injury have been reported, and only some of these have been fully validated. one of the most popular approaches is burn infliction by direct contact with the heat source. previous investigators have reported that the pressure of application of the contact burn infliction device does not affect the depth of injury. we hypothesized that the depth of injury would increase with increasing pressure of application in a porcine burn model. forty mid-dermal contact burns m ...201020616654
a role for factor xiia-mediated factor xi activation in thrombus formation in vivo.mice lacking factor xii (fxii) or factor xi (fxi) are resistant to experimentally-induced thrombosis, suggesting fxiia activation of fxi contributes to thrombus formation in vivo. it is not clear whether this reaction has relevance for thrombosis in pri mates. in 2 carotid artery injury models (fecl(3) and rose bengal/laser), fxii-deficient mice are more resistant to thrombosis than fxi- or factor ix (fix)-deficient mice, raising the possibility that fxii and fxi function in distinct pathways. a ...201020634381
micrornaome of porcine pre- and postnatal development.the domestic pig is of enormous agricultural significance and valuable models for many human diseases. information concerning the pig micrornaome (mirnaome) has been long overdue and elucidation of this information will permit an atlas of microrna (mirna) regulation functions and networks to be constructed. here we performed a comprehensive search for porcine mirnas on ten small rna sequencing libraries prepared from a mixture of tissues obtained during the entire pig lifetime, from the fetal pe ...201020634961
