introduction: to study the effects of polarized polychromatic noncoherent light (bioptron) therapy on patients with carpal tunnel syndrome (cts). methods: this study was designed as a randomized clinical trial. forty four patients with mild or moderate cts (confirmed by clinical and electrodiagnostic studies) were assigned randomly into two groups (intervention and control goups). at the beginn...

Oral biofilms are associated with the most common infections of the oral cavity. Bacteria embedded in the biofilms are less sensitive to antibacterial agents than planktonic bacteria are. Recently, an antibacterial synergic effect of noncoherent blue light and hydrogen peroxide (H(2)O(2)) on planktonic Streptococcus mutans was demonstrated. In this study, we tested the effect of a combination o...

OBJECTIVE Our aim was to assess the efficacy of polarized polychromatic noncoherent light (Bioptron light) in the treatment of idiopathic carpal tunnel syndrome. BACKGROUND Carpal tunnel syndrome is the most common compression neuropathy, but no satisfactory conservative treatment is available at present. METHOD An uncontrolled experimental study was conducted in patients who visited our cl...

This paper proposes a method for the generation of high-contrast localized sinusoidal fringes with spatially noncoherent illumination and relatively high light throughput. The method, somehow similar to the classical Lau effect, is based on the use of a Fresnel biprism. It has some advantages over previous methods for the noncoherent production of interference fringes. One is the flexibility of...

We introduce and theoretically investigate here a novel analytical method that we have called focal molography, in which molecular interactions are made visible through scattering of coherent light by a coherent pattern of molecules. The scattered light quantifies the presence of molecules at molecular interaction sites. It is separated from noncoherent background scatter by a combination of lo...

Photoresponsive materials that adapt their morphologies, growth directions, and growth rates dynamically in response to the local incident electromagnetic field would provide a remarkable route to the synthesis of complex 3D mesostructures via feedback between illumination and the structure that develops under optical excitation. We report the spontaneous development of ordered, nanoscale lamel...

The noncoherent demodulation of differentially phase-shift keyed signals transmitted simultaneously via a synchronous CDMA channel is studied under the assumption of white Gaussian background noise. A class of noncoherent linear detectors is defined with the objective of obtaining the optimal one. The performance criterion considered is near-far resistance, which denotes worst-case multiuser as...
