The ocean color monitor (OCM) sensor onboard OceanSat-2 is providing data in visible and near Infrared (NIR) bands. Due to the limited spectral coverage of OCM, widely used dark-target deep-blue aerosol algorithms cannot be adapted. Here, a new optical depth (AOD) retrieval algorithm for OCM (or similar sensors) over land, termed Space Applications Center AErosol Retrieval (SAER) described. It ...

We investigated the status and the regulation of the CDK inhibitor p27 in a choroidal melanoma tumour derived cell line (OCM-1). By contrast to normal choroidal melanocytes, the expression level of p27 was low in these cells and the MAP kinase pathway was constitutively activated. Genetic or chemical inhibition of this pathway induced p27 accumulation, while MAP kinase reactivation triggered a ...

An integrated multimodal optical microscope is demonstrated for high-resolution, structural and functional imaging of engineered and natural skin. This microscope incorporates multiple imaging modalities including optical coherence (OCM), multi-photon (MPM), and fluorescence lifetime imaging microscopy (FLIM), enabling simultaneous visualization of multiple contrast sources and mechanisms from ...

A fiber-based multimodal imaging system that combines multiphoton microscopy (MPM) with Fourier domain optical coherence microscopy (OCM) is reported. The system uses a fiber-based femtosecond laser, a fiber coupler, and a double-clad fiber (DCF) device. The fiber laser has a central wavelength of 1.04 μm and bandwidth of 29 nm. Longer excitation wavelength is used to increase penetration depth...

We present a feature extraction and tracking method which is based on pure rich texture analysis and has robustness under irregular conditions, such as illumination change, deformation of objects and so on. The method is composed mainly of two algorithms: Entropy Filtering and Orientation Code Matching (OCM). Entropy filter points up areas of images being messy distribution of orientation codes...

A Osteopatia craniomandibular (OCM) é uma doença rara, autolimitante que acomete animais jovens, entre três a oito meses e não tem caráter neoplásico. É caracterizada pela proliferação óssea atinge os ossos da mandíbula, mas também pode envolver outras estruturas como articulação temporomandibular, do crânio longos, causando dor desconforto. Foi atendido um cão, fêmea com quatro de idade algia ...

PURPOSE To study VP22 light controlled delivery of antisense oligonucleotide (ODN) to ocular cells in vitro and in vivo. METHODS The C-terminal half of VP22 was expressed in Escherichia coli, purified and mixed with 20 mer phosphorothioate oligonucleotides (ODNs) to form light sensitive complex particles (vectosomes). Uptake of vectosomes and light induced redistribution of ODNs in human chor...

The identification of a beta-cell tracer is a major quest in diabetes research. However, since MRI, PET and SPECT cannot resolve individual islets, optical techniques are required to assess the specificity of these tracers. We propose to combine Optical Coherence Microscopy (OCM) with fluorescence detection in a single optical platform to facilitate these initial screening steps from cell cultu...

Optical coherence microscopy (OCM) combines coherence gating, high numerical aperture optics, and a fiber-core pinhole to provide high axial and lateral resolution with relatively large depth of imaging. We present a handheld rigid OCM endoscope designed for small animal surgical imaging, with a 6-mm diam tip, 1-mm scan width, and 1-mm imaging depth. X-Y scanning is performed distally with mirr...
