Aneurysm clipping following endovascular coil embolization: A report of two cases

Abstract BACKGROUND: Treatment of intracranial aneurysms by Guglielmi detachable coil (GDC) embolization is a useful therapeutic alternative to surgery. This procedure is attractive as a minimally invasive approach to treat cerebral aneurysms; however, is not devoid of complications or failure and retreatment, with either a surgical or endovascular technique, may often be required. CASE REPORTS: Two cases are presented in which surgery was required after coil embolization. In one case, surgical treatment was performed one month later because of regrowth and subsequent bleeding of the aneurysm. In the second case, surgical treatment was carried out six months later because of recanalization …

New histone acetylation/deacetylation specific inhibitors: a novel and potential approach to cancer therapy

The acetylation status of histones is regulated in eukaryotes by two kinds of enzymes, histone acetyltransferases (HATs) and histone deacetylases (HDACs), which are responsible for acetylation and deacetylation of lysines residues in N-terminal tails of histone.[1] Thus acetylation, together with phosphorylation and methylation of N-terminal tail of histones, are involved in regulating fundamental processes, such as proliferation and cell death.[2-3] Sodium butyrate, which belongs together with valproic acid to the class of short chain fatty acids, was the first HDAC inhibitor (HDACI) to be identified.[1] Organotin compounds have various influences on physical function including the hormone…
