The synthesis, characterization, and spectral properties of strategically designed boronic acid containing fluorescent sensors, o-, m-, p-BMOQBA, for the potential detection of tear glucose concentrations when immobilized in plastic disposable contact lenses is described. The new probes, BMOQBAs, consist of the 6-methoxyquinolinium nucleus as a fluorescent indicator, and the boronic acid moiety...

Headlamps on vehicles are primarily responsable for illuminating the traffic space during periods of low visibility, such as night or precipitation. In addition, headlamps are also considered as a cosmetic part, playing an important role in the car styling. Because of this, carmakers request a great precision for surface defect detection in all the headlamp components. One of these components i...

Light emitted from single-mode semiconductor lasers generally has large divergence angles, and high numerical aperture lenses are required for beam collimation. Visible and near infrared lasers are collimated using aspheric glass or plastic lenses, yet collimation of mid-infrared quantum cascade lasers typically requires more costly aspheric lenses made of germanium, chalcogenide compounds, or ...

purpose: to report clinical outcomes of crystalline lens extraction and iris claw artisan intraocular lens (iol) implantation in patients with lens subluxation secondary to marfan syndrome.  methods: this retrospective study enrolled 14 eyes of 12 marfan patients with lens subluxation who underwent crystalline lens removal and artisan iol implantation. pre- and post-operative data, including pa...

OBJECTIVE The undergraduate medical curriculum has been overcrowded with core learning outcomes with no formal exposure to plastic surgery. The aim of this study was to compare medical students from two educational settings for the basic understanding, preferred learning method, and factors influencing a career choice in plastic surgery. DESIGN AND SETTING A prospective cohort study based on ...

OBJECTIVE To describe the geographic and temporal trends in cosmetic facial plastic surgery procedure costs and frequency during the last decade and to evaluate factors that may influence changes in the demand for cosmetic procedures. METHODS A survey sent to every (N = 1727) active fellow, member, or associate of the American Academy of Facial Plastic and Reconstructive Surgery assessing the...

Achieving a level of technical skill and confidence in surgical operations is the main goal of plastic surgical training. Operating rooms were accepted as the practical teaching venues of the traditional apprenticeship model. However, increased patient population, time, and ethical and legal considerations made preoperation room practical work a must for plastic surgical training. There are sev...

BACKGROUND Exposure to plastic surgery during medical school is limited. Most interested applicants form their perceptions of careers in this surgical specialty during elective rotations. OBJECTIVE To investigate the perceptions of Canadian medical students considering a career in plastic surgery. The results obtained were then compared with current Canadian plastic surgery residents' percept...

the purpose of this investigation was to study and compare the electrophoretic patterns of optic lensproteins of different species of domestic animals at pre- and post-natal ages. optic lenses were removed from the embryo or adult sheep, cattle, goat, camel and chicken at the slaughter-house then homogenized and subjected to sodium dodecylsulfate polyacrylamide gel electrophoresis (sds-page). i...
