Inner Retinal Oxygen Extraction Fraction in Response to Light Flicker Stimulation in Humans.
PURPOSE Light flicker has been shown to stimulate retinal neural activity, increase blood flow, and alter inner retinal oxygen metabolism (MO2) and delivery (DO2). The purpose of the study was to determine the change in MO2 relative to DO2 due to light flicker stimulation in humans, as assessed by the inner retinal oxygen extraction fraction (OEF). METHODS An optical imaging system, based on ...
متن کاملThe effect of eight weeks of moderate-intensity endurance training on myocardial capillary density, ejection fraction and left ventricular shortening fraction in male rats with myocardial infarction
Background and objective: Vascular obstruction and impaired blood flow and oxygen delivery cause a myocardial infarction and limit a personchr('39')s function. Therefore, finding a way to create new arteries and replace blocked arteries has always been of interest to researchers, including exercise physiologists. Therefore, this study was conducted to evaluate the effect of eight weeks of moder...
متن کاملUltrasound assisted extraction and determination of the carbohydrate fraction in marine sediments
In this paper, an ultrasound±acetic acid procedure for the simultaneous extraction and hydrolysis of carbohydrates in marine sediments prior to their colorimetric determination is described. The main advantage of the proposed procedure is the improved analytical accuracy achieved. Extraction and hydrolysis are quantitative since the oxidative reactions which cause the underestimation of the tot...
متن کاملRetinal oxygen extraction in humans
Adequate function of the retina is dependent on proper oxygen supply. In humans, the inner retina is oxygenated via the retinal circulation. We present a method to calculate total retinal oxygen extraction based on measurement of total retinal blood flow using dual-beam bidirectional Doppler optical coherence tomography and measurement of oxygen saturation by spectrophotometry. These measuremen...
متن کاملdevelopment of 116 kda fraction for detecting experimental toxoplasma gondii infections in mice.
background: serological diagnosis of toxoplasma gondii infection using crude antigens may not be more accurate. to increase the diagnostic potency of anti-gens, isolation of their immunogenic fractions could be useful. the current re-search adopted to obtain an affinity isolated fraction from rh strain using cnbr sepharose 4b column coupled with infected mice sera helping in detec-tion of igm a...
