Although late-phase (>35min post-administration) 11C-PiB-PET has good sensitivity in cerebral amyloid angiopathy (CAA), its specificity is poor due to frequently high uptake in healthy aged subjects. By detecting perfusion-like abnormalities, early-phase 11C-PiB-PET might add diagnostic value. Early-frame (1-6min) 11C-PiB-PET was obtained in 11 non-demented patients with probable CAA-related sy...

late ripening citrus cultivars are very acceptable in the market. with respect to scarcity of late ripening citrus cultivars in iran, the project was conducted to produce a new late ripening cultivar for 21 years (1989-2009). the first phase (1989-1993) was started with controlled pollination between mineolla tangelo (citrus paradisi × c. reticulata) and changsha mandarin (c. changsha). after a...

Contact sensitivity (CS) is an inflammatory disorder characterized by early and late phases of leukocyte recruitment. We used a noninvasive intravital microscopy technique allowing for the direct visualization of leukocyte rolling and adhesion on blood vessel endothelium. By blocking specific adhesion molecules, we elucidated the molecular mechanisms mediating early leukocyte recruitment to be ...

In inter-enterprise business service collaborations management of nonfunctional properties has become a fundamental issue, as business management and computing infrastructures are expected to align more closely. Already, serviceoriented computing emphasizes dynamic binding between the functional elements participating in service collaborations and late encapsulation of properties on them. In su...

Multiple Unit Activity (MUA) of the hypothalamic arcuate nucleus as indicated by discriminated spikes with window setting between 18-30 uV, the integrated MUA and the cortical EEG of the urethane anaesthetized rats on the proestrous day was recorded with the help of a polygraph. Infusion of LH-RH in the 3rd ventricle markedly increased the arcuate nucleus MUA. The effect started within minutes ...

The relationship between two menstrual cycle phases and cardio respiratory fitness in athletes on oral contraceptives and not on oral contraceptives was assessed in a pilot study. Twelve endurance-trained college cross country runners underwent maximal oxygen consumption treadmill testing, during the late follicular/ovulatory phase and late luteal/premenstrual phase of their menstrual cycle. No...

QoS-aware dynamic binding of composite services provides the capability of binding each service invocation in a composition to a service chosen among a set of functionally equivalent ones to achieve a QoS goal, for example minimizing the response time while limiting the price under a maximum value. This paper proposes a QoS-aware binding approach based on Genetic Algorithms. The approach includ...

To be able to compose and decompose software components at run time, some form of dynamic rebinding between components (or objects) is needed. In this paper, we identify basic properties of dynamic object (re)binding, and propose a class-based object calculus that gives precise meaning to these properties. We also define two example semantic properties that are characteristic for many concurren...
