Delayed examination of synovial fluid by ordinary and polarised light microscopy to detect and identify crystals.
OBJECTIVE To determine the reliability of a delay in the microscopic examination of synovial fluid (SF) to detect and identify crystals. METHODS Ninety one SF samples were examined, 31 with monosodium urate (MSU) crystals, 30 with crystals of calcium pyrophosphate dihydrate (CPPD), and 30 containing no crystals. The specimens were stored with EDTA, sodium heparin, and without anticoagulant at...
متن کاملPolarisation Vision: Beetles See Circularly Polarised Light
It has long been known that the iridescent cuticle of many scarab beetles reflects circularly polarised light. It now turns out that scarabs can also see this light, potentially using it as a covert visual signal.
متن کاملPolarised light microscopy: principles and practice for the rheumatologist.
Polarised light microscopy is used to detect and measure matter (in fluids, tissues, or cells) that has crystalline or crystalline-like properties. Because light has electromagnetic properties, it can be influenced by the electromagnetic properties of material through .which it passes. In many materials this influence is equal in whatever direction the light is vibrating. But crystalline materi...
متن کاملPhotonic crystals of coated metallic spheres
It is shown that simple face-centered-cubic (fcc) structures of both metallic and coated metallic spheres are ideal candidates to achieve a tunable complete photonic bandgap (CPBG) for optical wavelengths using currently available experimental techniques. For coated microspheres with the coating width to plasma wavelength ratio lc/λp ≤ 10% and the coating and host refractive indices nc and nh, ...
متن کاملMetallic photonic crystals at optical wavelengths
We theoretically study three-dimensional metallic photonic-band-gap ~PBG! materials at near-infrared and optical wavelengths. Our main objective is to find the importance of absorption in the metal and the suitability of observing photonic band gaps in this structure. For that reason, we study simple cubic structures and the metallic scatterers are either cubes or interconnected metallic rods. ...
