Line profiles

obtained from the simulation are compared to our experimentally obtained data. Initial energy distribution for atoms is approximately calculated from the measured line profiles while the initial angle distribution was taken to be cosine. Balmer alpha intensity was found to exponentially decay in the negative glow region, which concurs with the experimental results. see more These agreements between the simulation and experiment support the collision model for excessive line broadening.”
“We analyzed the polychlorinated biphenyls (PCBs) in human hair collected from an electronic waste (e-waste) recycling area in southern China and compared their composition profiles and chiral signatures to those of workplace and domestic dust. The PCB concentrations showed significant age dependence in dismantling workers’ hair but not in residents’ hair. Among residents, PCB concentrations decreased in the following order: elderly people > students > pre-school children > adults. The PCB homologue and congener profiles of the workers’ hair were similar to those of the workplace dust. However, the PCB homologue profile of the residents’ hair was clearly different from that of the domestic dust. The chiral congener CB95 generally exhibited a racemic or near-racemic composition in both hair and dust, with enantiomer fractions selleck chemical (EFs) ranging from

0.485 to 0.525 in hair and from 0.479 to 0.504 in dust. The EFs of CB132 in dust (0.477-0.513) were closer to a racemic chiral signature than those in hair (0.378-0.521), but this difference was not significant. this website Our results suggest that the chiral signature of PCBs may be a better tool than the PCB composition profile for identifying the external and internal sources of organic contaminants in human hair. Further measurements of chiral PCB signatures in hair and blood from the same individuals are needed to identify the external and internal sources

of PCBs in human hair. (C) 2013 Elsevier Ltd. All rights reserved.”
“Eclampsia is rare in molar pregnancy. Sudden cortical blindness in eclampsia is an uncommon but very dramatic experience for the patient. Because of its rarity, blindness associated with eclampsia may pose a significant problem for the obstetrician.

We describe cortical blindness and posterior reversible encephalopathy syndrome (PRES) complicating molar pregnancy-related eclampsia. The clinical presentation in our patient was consistent with PRES associated with eclampsia together with magnetic resonance imaging (MRI) findings.

Preeclampsia and eclampsia are regarded as common causes of PRES, which is considered to be the result of vasogenic brain edema caused by a rapid raise in blood pressure. Clinical and imaging findings are usually reversible. Early diagnosis and elimination of possible causes are important in order to avoid permanent visual or brain injury.
