The results show that PEI-PHEG could effectively form positively

The results show that PEI-PHEG could effectively form positively charged nanosized particles with pDNA; the particle size was in a range of 130.2 to 173.0 nm and the zeta potential was in a range of 27.6 to 41.0 mV. PEI-PHEG exhibited much lower cytotoxicity and higher gene transfection efficiency than PEI-25K with different cell lines in vitro. An animal test was also conducted on a Lewis Lung Carcinoma

tumor model in C57/BL6 mice by using subcutaneous intratumoral administration. The results show that in vivo transfection efficiency of PEI-PHEG was improved greatly compared with that of commercial PEI-25K. These results PF-00299804 supplier demonstrate that PEI-PHEG can be a potential nonviral vector for gene delivery systems both in vitro and in vivo. (C) 2011 Wiley Periodicals, Inc.

“Systematic reviews represent a specific type selleck chemical of medical research in which the units of analysis are the original primary studies. They are essential tools in synthesizing available scientific information, increasing the validity of the conclusions of primary studies, and identifying

areas for future research. They are also indispensable for the practice of evidence-based medicine and the medical decisionmaking process. However, conducting high quality systematic reviews is not easy and they can sometimes be difficult to interpret. This special article presents the rationale for carrying out and interpreting systematic reviews and uses a hypothetical example to Selleckchem Nepicastat draw attention to key-points.

“Assessment

for epilepsy surgery may require invasive measures such as implantation of intracranial electrodes or the Wada test. These investigations are commonly well tolerated. However, complications, including visual disturbances of various etiologies, have been reported. Here we describe two patients with pharmacoresistant temporal lobe epilepsy (TLE) who displayed loss of vision in the context of presurgical assessment and in whom mutations associated with Leber’s hereditary optic neuropathy (LHON) were detected. Genetic analysis revealed in one patient the frequent mitochondrial G11778A LHON mutation in ND4. In the second patient, the mitochondrial C4640A mutation in ND2 was detected. This rare LHON mutation enhanced the sensitivity of the patient’s muscle and brain tissue to amobarbital, a known blocker of the mitochondrial respiratory chain. Mitochondrial dysfunction has been reported in epilepsy. Thus, the presence of LHON mutations can be a rare cause of visual disturbances in patients with epilepsy and may have predisposed to development of epilepsy. (c) 2010 Elsevier Inc.
