The histopathological approach revealed marked changes in the Purkinje cells, myleinated nerve fibers and granular cells of ASP-treated animals. Some of these cells appeared with deeply stained PCI-32765 cell line cytoplasm. Ultrastructural examination showed Purkinje cells with dilated rough endoplasmic reticulum and condensed mitochondria. Granular cells appeared with less c nuclei and surrounded by dissolution of most Mossy rosettes structures. Most myelinated nerve fibers showed thickening of myelinated sheath and others showed splitting of their myelin sheath. The histopathological,

immunohistochemical and ultrastructural alterations were much less observed in concomitant use of P. anisum oil with ASP. Cerebellar cortex is considered target areas of ASP neurotoxicity, while P. anisum oil, when used in combination with ASP displays a protective action against neurotoxicity.”
“One new tetralone, monaspurpurone (1), was isolated from the EtOH extract of a yellow mutant of the fungus Monascus purpureus BCRC 38113 (Eurotiaceae) grown on rice,

along with five known compounds, -sitosteryl palmitate (2), ergosterol (3), ankaflavin (4), monascin (5) and p-nitrophenol (6). They were characterised on the basis of spectral analysis and comparison with literature data. All the isolates were also evaluated for the scavenging properties towards the DPPH in TLC autographic and spectroscopic assays.”
“Phytochemical investigation of the aerial parts of Abies holophylla led to the isolation of two new and 40 known compounds. Their structures were established primarily Selleckchem Small molecule library by 1D and 2D NMR spectroscopic techniques. Compound 19 showed the most significant activity against the A549 lung Selleckchem Cyclopamine cancer cell line with an IC50 value of 10.3 mu g/mL. (C) 2012 Phytochemical Society of Europe.

“Crinophagy is a well-described ultraphysiological phenomenon encountered in a variety of cells and tissues. This process reflects a form of autophagy in which degradation of excess or nonfunctional cellular constituents occurs, specifically of neuroendocrine granules. The diagnostic ultrastructural features are the identification of neuroendocrine

granules within lysosomes, often encased in or accompanied by myelin bodies. An impressive variety of neuroendocrine/secretory cells and tumors have demonstrated crinophagy from the neuroendocrine cells of the pancreas, small bowel, prostate, and urinary tract. To our knowledge, however, crinophagy has not been previously described in neuroblastoma, despite the fact that these tumors characteristically produce neuroendocrine granules in abundance. This case further supports the idea that crinophagy represents a common ultrastructural mechanism for the disposal and degradation of excess neuroendocrine granules.”
“Resveratrol (1) and oxyresveratrol (2) are phytoalexins with antioxidant activities (AAs) and proposed effects against several pathological processes.
