Nine patients with pure dysarthria underwent computed tomography or magnetic resonance imaging. Eight patients had infarcts of lacunar or larger size in the internal capsule: four in the superior portion of the anterior limb or adjacent corona radiata and four in the superior portion of the genu or the adjacent corona radiata. In one patient, there was a small infarct in the bulbar motor cortex...

Diffusion tensor imaging is a magnetic resonance method which provides quantitative measurements of the directionality (anisotropy) of diffusion. Anisotropy measurements can be used to obtain quantitative information about the microstructural integrity of white matter tracts. In intact tracts diffusion is restricted and directional because water molecules move predominantly longitudinally to tr...

Successive extracts of whole plant of Actiniopteris radiata screened for its therapeutic potential as an antiallergic and antistress agent in asthma using specific in vivo animal models. Only ethanol extract (AREE) at a higher dose of 100 mg/kg i.p significantly (p < 0.05) decreased milk induced eosinophilia by 16.20 ± 2.235 when compared with control group while even lower doses of 50 mg/kg, i...

In the present investigation the effect of cobalt chloride (CoCl ), ethylene biosynthesis inhibitor and 2 silver nitrate (AgNO ), ethylene perception inhibitor was studied on the seed germination of Vigna radiata. 3 While ethylene slightly promoted germination, both the inhibitors decreased the germination percentage. However, Ag was more effective in retarding germination than Co . A combined ...

We compared the performance of mycorrhiza-inoculated and non-inoculated radiata pine (Pinus radiata D. Don) seedlings in two field studies. In the first study, above ground growth of 2-year-old container-grown trees was compared after planting in two areas that differed in water availability. Mycorrhizal inoculation significantly improved above ground growth in the 2 years after planting in bot...

Sorption behaviour of radiata pine has been investigated by weighing small specimens continuously during isothermal step changes in relative humidity. The use of wood specimens shorter in the longitudinal direction than the average tracheid length of radiata pine ensures that all tracheids in a specimen are exposed, reducing the effect of wood structure on bound water transport. The small size ...

The plant pathogenic fungus, Fusarium circinatum, is the cause of a major epidemic of pitch canker in urban forests of Monterey pine (Pinus radiata) in California. This pathogen is now also well established in all three mainland, native populations of Monterey pine where it causes conspicuous branch die-back and, frequently in association with native bark beetles, increased tree mortality. In t...

Environmental estrogens have recently caused great concern because of their ability to mimic natural hormones and influence vital endocrine functions in humans and wildlife. The induction of vitellogenin (Vtg) synthesis by environmental estrogens in viviparous vertebrates has been proposed as an effective and sensitive biomarker of estrogenicity. Immunochemical analysis of plasma from Atlantic ...

The biology and ecology of Psyllaphycus diaphorinae Hayat, a potential natural enemy of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), is poorly understood. In April 2013, six P. diaphorinae females collected from Punjab, Pakistan emerged from parasitized Asian citrus psyllid nymphs in quarantine at the University of California, Riverside and were used to initiate co...
