The lung could be the target organ to cellular damage, since it is directly exposed to high concentrations of oxygen. Acute exercise and age would be an added challenge to the lung, and therefore, we investigated alterations of major lung antioxidant enzymes (manganese-superoxide dismutase, Mn-SOD; copper-zinc-SOD, Cu-Zn-SOD; glutathione peroxidase, GPX;(More)
1 D iabetic retinopathy is characterized by increased vascular permeability, ischemia, and neovascularization. Ischemia in the retina can induce neovas-cularization via induction of vascular end o t h e l i a l g r o w t h f a c t o r (V E G F) expression by the transcription factor hy-poxia-inducible factor-1 (1). Hypoxia is also the main stimulus for(More)
The relative complex dielectric permittivity, ⑀*ϭ⑀ЈϪi⑀Љ, of ice has been measured in the frequency range 5–39 GHz and in the temperature range 190–265 K. The cavity resonator method at 5 and 10 GHz and the open resonator method at 33 and 39 GHz were used to determine the low dielectric loss of ice. The real part of permittivity ⑀Ј was independent of the(More)
Calcium deficiency is considered to increase intracellular calcium level; thus the aim of the current study was to elucidate whether dietary calcium restriction enhanced exercise-induced oxidative stress in rat diaphragm. Twenty male Wistar rats were randomly assigned to either a control group or a group subjected to 1 mo of calcium restriction. In(More)
This paper describes a model-based grasp planner for an articulated multi-fingered robotic hand. The planner searches for an initial grasp from which a required continuous motion of an object is achieved using fingertips alone while keeping rolling contact with the object. An adaptive search strategy has been developed and implemented : the error analysis(More)
