Ulinastatin promotes T lymphocyte apoptosis in rats with severe acute pancreatitis via mitochondrial pathways

C. L. Wang, Li, N., Ma, T., Zhang, P., and You, S. Y., Ulinastatin promotes T lymphocyte apoptosis in rats with severe acute pancreatitis via mitochondrial pathways, vol. 14, pp. 5511-5518, 2015.

We explored the influence of ulinastatin on apoptosis of T lymphocytes in rats with severe acute pancreatitis (SAP) and the effect of ulinastatin on mitochondrial apoptosis pathways in spleen lymphocytes. Thirty-six Wistar rats were randomly divided into three groups (N = 12): a sham operated group, a SAP group, and an ulinastatin-treated SAP group. The SAP model was established by injecting 5% sodium taurocholate into the intrapancreatobiliary duct. Study rats were sacrificed after 24 h, and splenic lymphocytes were then collected.

Bovine herpesvirus type 5 infection regulates Bax/BCL-2 ratio

A. F. Garcia, Novais, J. B., Antello, T. F., Silva-Frade, C., Ferrarezi, M. C., Flores, E. F., and Cardoso, T. C., Bovine herpesvirus type 5 infection regulates Bax/BCL-2 ratio, vol. 12, pp. 3897-3904, 2013.

Bovine herpesvirus 5 (BoHV-5) is an α-herpesvirus that causes neurological disease in young cattle and is also occasionally involved in reproductive disorders. Although there have been many studies of the apoptotic pathways induced by viruses belonging to the family Herpesviridae, there is little information about the intrinsic programmed cell death pathway in host-BoHV-5 interactions. We found that BoHV-5 is able to replicate in both mesenchymal and epithelial cell lines, provoking cytopathology that is characterized by cellular swelling and cell fusion.

Evaluation of a method for high yield purification of largely intact mitochondrial DNA from human placentae

S. U. Dani, Gomes-Ruiz, A. Cristina, and Dani, M. Angela C., Evaluation of a method for high yield purification of largely intact mitochondrial DNA from human placentae, vol. 2, pp. 178-184, 2003.

We developed, and quantitatively and qualitatively evaluated an easily reproducible method for high yield purification of mitochondrial DNA (mtDNA) from human placentae by mechanical tissue disruption, differential centrifugation of mitochondria, enzymatic digestion, phenol extraction and ethanol precipitation. Average mtDNA yields were 2.5 µg/g tissue (without an RNAse treatment step) and 1.5 µg/g tissue (with an RNAse treatment step).
