PURPOSE To evaluate the in vivo and in vitro properties of collagen-coated acrylic microspheres and to compare them with polyvinyl alcohol (PVA) particles. METHODS Samples of 100- to 300-microns, 300- to 500-microns, 500- to 700-microns, and 700- to 900-microns collagen-coated acrylic microspheres and 200- to 300-microns PVA particles were suspended in solutions of 50% saline and 50% contrast...

During embryonic development, large numbers of apoptotic cells are rapidly cleared by phagocytes. In this issue, Kurant et al. (2008) describe a new phagocytic receptor, called six-microns-under (SIMU), that promotes engulfment of apoptotic neurons by glial cells in the developing nervous system of Drosophila.

Application of gravity and magnetic separation methods to upgrade low grade Manganese ores from Venaj Mine has been reported elsewhere. This paper discusses the results of flotation tests, as well as combination of flotation and magnetic method to concentrate fine particles (less than 150 microns) of manganese ore. Results obtained from various direct and reverse flotation tests, using differen...

Herein, we report the draft genome sequence of Enterococcus faecalis ED-NGS-1009, cultivated from a blood sample taken from a neonatal sepsis patient at the Royal Infirmary in Edinburgh, Scotland, United Kingdom.

During experimental studies of the equal-channel angular pressing-drawing effect on microstructure evolution and mechanical properties change, principal possibility effectiveness using proposed continuous method for forming an ultrafine-grained structure increasing strength steel-aluminum wire was proved. The deformation carried out at ambient temperature in three passes. It is shown that both ...

PURPOSE To provide normal macular thickness measurements using Spectral Domain Optical Coherence Tomography (SDOCT, Copernicus, Optopol Technologies, Zawierci, Poland). METHODS Fifty-eight eyes of 58 healthy subjects were included in this prospective study. All subjects had comprehensive ophthalmic examination including best-corrected visual acuity (BCVA). All the subjects underwent Copernicu...

Mesoscale structures (microns dimensions, nL-pL volumes) have been designed and fabricated in silicon for use in various analytical tasks. We studied sperm motility and performed sperm selection in channels (80 microns wide x 20 microns deep), branching structures (40 microns wide x 20 microns deep, eight bifurcations), and channels containing barriers (7 microns feature size). Sperm-cervical m...

PURPOSE To demonstrate the feasibility of measuring the anterior structures of the human eye by partial coherence interferometry and to determine its precision for eyes under normal and cycloplegic conditions. METHODS The dual-beam version of partial coherence interferometry, a recently developed noninvasive optical ranging technique, enables high resolution measurements of several intraocula...

Micro-electro-mechanical systems (MEMs) are Combination of electrical and mechanical components in Micron dimensions. In recent years, holding, actuating methods and handling of MEMs components such as microgripper, microsensors and etc. have been deeply studied. Microgrippers for handling, positioning and assembling of micro components are very useful so that for clamping need actuation create...
