Background: Hirsutism is a common clinical problem with different etiologic factors. Hence, clinical and laboratory studies are necessary to find these factors. Objectives: To determine the etiologic factors of hirsutism with clinical and paraclinical studies including TSH, DHEA-S, LH/FSH, testosterone, prolactin, 17-OH progesterone and sonography of ovary. Patients and Methods: This cross sect...

PURPOSE To compare quantitatively three techniques to measure the optical aberrations of the human eye: laser ray tracing (LRT), the Hartmann-Shack wavefront sensor (H-S), and the spatially resolved refractometer (SRR). LRT and H-S are objective imaging techniques, whereas SRR is psychophysical. METHODS Wave aberrations were measured in two normal subjects with all three techniques implemente...

Mammalian cell-based bioprocesses are used extensively for production of therapeutic proteins. Off-line monitoring of such cultivations via manual sampling is often labor-intensive and can introduce operator-dependent error into the process. An integrated multi-functional off-line analyzer, the BioProfile FLEX (NOVA Biomedical, Waltham MA) has been developed, which combines the functionality of...

plastic recycling is the process of recovering scrap or waste plastics and reprocessing thematerial into useful products that sometimes differ completely in form from their original state. an importantissue in plastic recovery and recycling is that plastic waste usually contains a variety of plastics that differ intheir physical and chemical properties. separation of recovered plastics into dis...
