In this study, the effects of limited hydrolysis and/or high-pressure homogenization (HPH) treatment in acid conditions on the functional properties of oyster protein isolates (OPI) were studied. Protein solubility, surface hydrophobicity, particle size distribution, zeta potential, foaming, and emulsifying properties were evaluated. The results showed that acid treatment led to the dissociatio...

Oral Proficiency Interview: Based on the guidelines established by the American Council of Teaching of Foreign Languages (ACTFL). The interview ill be conducted by an outside examiner who has not had the student in class. Strengths and weaknesses in student performance are discussed at subsequent LFS Faculty Council Meetings and used for program review and revision purposes. 80% of students ach...

ACTFL generic proficiency guidelines describe what learners are able to perform at various proficiency levels. These guidelines, in particular the oral proficiency guidelines (OPG), have been widely used to assess learners’ proficiency across institutions – via the oral proficiency interview (OPI) technique – irrespective of curriculum, teaching methods, and materials. Many institutions and org...

PURPOSE The Ocular Protection Index (OPI) 2.0 System was developed to evaluate ocular surface protection under a natural blink pattern and normal visual conditions. The OPI 2.0 System implements fully automated software algorithms which provide a real-time measurement of corneal exposure (breakup area) for each interblink interval during a 1-minute video. Utilizing this method, the mean breakup...

Methyl parathion (C8H10NO5PS) and parathion (C10H14NO5PS) are both organophosphate insecticides (OPI) widely used for household and agricultural applications. They are known for their ability to irreversibly inhibit acetylcholinesterase which often leads to a profound effect on the nervous system of exposed organisms. Many recently published studies have indicated that human exposure to OPI may...

Background. Emergency airway management (AM) is a priority when resuscitating critically ill or severely injured patients. The goal of this study was to determine the success rates of LT insertion during AM. Methods. Studies that included LT first-pass insertion (FPI) and overall-pass insertion (OPI) success by emergency medical services and in-hospital providers performing AM for emergency sit...
