Changes in hippocampal ultrastructure and vimentin expression in rhesus monkeys following selective deep hypothermia and blood occlusion

B. C. Li, Fu, X., Niu, X. Q., Fan, Y. D., Xu, W., Zhao, X. X., and Pu, J., Changes in hippocampal ultrastructure and vimentin expression in rhesus monkeys following selective deep hypothermia and blood occlusion, vol. 14, pp. 651-658, 2015.

Previous studies have shown that selective cerebral profound hypothermia combined with antegrade cerebral perfusion can improve resistance to cerebral hypoxia-ischemia in monkeys. The aim of this study was to observe the effect of selective cerebral profound hypothermia on the ultrastructure and vimentin expression in monkey hippocampi after severe cerebral ischemia. Eight healthy adult rhesus monkeys were randomly divided into two groups: profound hypothermia (N = 5) and normothermia (N = 3).

Activity and expression of polygalacturonase vary at different fruit ripening stages of sweet pepper cultivars

S. S. Ahmed, Gong, Z. - H., Khan, M. A., Yin, Y. - X., Guo, W. - L., and Imran, J., Activity and expression of polygalacturonase vary at different fruit ripening stages of sweet pepper cultivars, vol. 10, pp. 3275-3290, 2011.

Activity and expression of polygalacturonase (PG), a hydrolytic enzyme involved in ultrastructural changes in the pericarp of sweet pepper (Capsicum annaum), were investigated at different ripening stages of the pepper cultivars Mandi and Talanduo. Molecular cloning of CaPG was carried out by constructing a cDNA library from three stages of fruit ripening. Morphological determination, PG assay, RT-PCR, and ultrastructural studies were used to quantify changes in CaPG gene expression in the pericarp from green, color change and fully ripened stages.
