PURPOSE To determine if there is a difference in antibiotic sensitivity to coagulase-negative Staphylococcus (CNS) cultured from the host versus the donor cornea at the time of corneal transplantation. Then to apply this knowledge to preoperative preparation of patients undergoing eye surgery. METHOD A total of 923 donor corneas stored in Optisol and 895 host corneas with no preoperative anti...

This study aims to evaluate the effect of the duration of high-altitude (HA) pre-exposure on human neurobehavioral parameters including mood states and cognitive performance at HA. One hundred and eleven healthy individuals (ranging in age from 18 to 35 years) were recruited to participate in this study. They were divided into two groups: a 4-day short-term HA pre-exposure group (n=57) and a 3-...

BACKGROUND It is a well-established fact that cigarette smoking causes degenerative, inflammatory, and respiratory diseases in humans. Because many factors such as air pollution and harsh working conditions can easily be eliminated in animal studies, we conducted this study to identify the effect of tobacco on rat trachea. METHODS 24 male Wistar rats were divided randomly into an experimental...

Measurement of regional cerebral blood flow (rCBF) was performed in 6 healthy baboons during ventilation with 35% stable xenon in artificial air. rCBF was measured with the intraarterial xenon-133 method. EEG was recorded continuously. All CBF areas of interest over one hemisphere reacted in the same way. Mean flow increased during short-term exposure to stable xenon and decreased if stable xen...

Since the early days of human life on the Earth, our skin has been exposed to different levels of light. Recently, due to inevitable consequences of modern life, humans are not exposed to adequate levels of natural light during the day but they are overexposed to relatively high levels of artificial light at night. Skin is a major target of oxidative stress and the link between aging and oxidat...

We investigated associations between ambient air pollution and microvessel function measured by peripheral arterial tonometry between 2003 and 2008 in the Framingham Heart Study Offspring and Third Generation Cohorts. We measured particulate matter with aerodynamic diameter ≤2.5 µm (PM2.5), black carbon, sulfates, particle number, nitrogen oxides, and ozone by using fixed monitors, and we deter...

Non-native, or 'foreign-accented,' speech deviates from native pronunciation norms, and these deviations can cause perceptual difficulty for listeners. However, there is reason to believe that non-native speech can be learned by the adult perceptual system. The present study investigated perceptual learning of foreignaccented speech with very limited experience. Sixteen auditory sentences were ...
