The EO properties of ZnTe were investigated by optical confinement with an electric field. The effect of the applied electric field and the rotation of polarization wave effect are discussed. (C) 2012 The Japan Society of Applied Physics”
“A survey was conducted to determine the diversity and frequency of endemic entomopathogenic nematodes (EPN) in citrus orchards in the Western Cape, Eastern Cape and Mpumalanga provinces of South Africa. The main aim of the survey was to obtain nematodes as biological control agents against false

codling moth (FCM), Thaumatotibia leucotreta, a key pest of citrus in South Africa. From a total of 202 samples, 35 (17%) tested positive for the presence of EPN. Of these, four isolates (11%) were found selleck chemicals llc to be steinernematids, while 31 (89%) were heterorhabditids. Sequencing and characterisation of the internal transcribed GSK3326595 spacer (ITS) region was used to identify all nematode isolates to species

level. Morphometrics, morphology and biology of the infective juvenile (IJ) and the first-generation male were used to support molecular identification and characterisation. The Steinernema spp. identified were Steinernema khoisanae, Steinernema yirgalemense and Steinernema citrae. This is the first report of S. yirgalemense in South Africa, while for S. citrae it is the second new steinernematid to be identified from South Africa. Heterorhabditis species identified include Heterorhabditis bacteriophora, Heterorhabditis zealandica and an unknown species of Heterorhabditis. Laboratory bioassays, using 24-well bioassay disks, have shown isolates of all six species found during the survey, to be highly virulent against the last instar of FCM larvae. S. yirgalemense, at a concentration of 50 IJs/FCM larva caused 100% mortality and 74% at a concentration of 200 IJs/pupa. Using a sand bioassay, S. yirgalemense gave 93% control of cocooned pupae and emerging moths at a concentration of 20 IJs/cm(2). This is the first report on the potential use of EPN to control the soil-borne

life stages of FCM, which includes larvae, pupae and emerging moths. It was shown that emerging moths were infected with nematodes, which may aid in control and dispersal. (C) 2011 Elsevier Inc. All rights reserved.”
“Background: Selleckchem Dibutyryl-cAMP Matrix metalloproteinase-9 (MMP-9) plays a key role for the blood-brain barrier disruption and intravenous tissue plasminogen activator (iv-tPA) therapy increases MMP-9. Edaravone, a free radical scavenger, reduces MMP-9-related blood-brain barrier disruption. We aimed to investigate whether edaravone would suppress the MMP-9 increase after iv-tPA using low-dose alteplase (0.6 mg/kg). Subjects: Patients hospitalized within 12 hours after ischemic stroke onset between April 2008 and June 2013 were retrospectively examined.
