Background & Objectives: Oral submucous fibrosis (OSMF) is a condition where excessive deposition of dense collagen fibers occurred in the connective tissue of oral mucosa. An alteration of collagen necessitates an in depth understanding of collagen in oral tissues as no breakthrough studies have been reported. Therefore the aim was to correlate the clinical, functional and histopathol...

In the chick limb bud, the zone of polarizing activity controls limb patterning along the anteroposterior and proximodistal axes. Since retinoic acid can induce ectopic polarizing activity, we examined whether this molecule plays a role in the establishment of the endogenous zone of polarizing activity. Grafts of wing bud mesenchyme treated with physiologic doses of retinoic acid had weak polar...

The polarimetric vector is a more general descriptor of light than intensity information alone, and it contains physical information about the imaged objects in a scene that traditional intensity based sensors ignore. Polarimeters – devices that measure polarization – are used to extract physical features from an image such as specularities, occluding contours, and material properties. Scientis...

Background: Temporomandibular joint (TMJ) is a stress bearing structure. Its resilience and functions are supported by collagen architecture. Visualization of this collagen networking can be done under polarizing microscope. This network gets modified in a variety of conditions affecting the TMJ likeankylosis, degenerative joint disorder, neoplastic conditions, trauma and ageing. The objective ...

Micromorphological investigation of soils is a powerful tool for studying the transformation under influence various weathering mechanisms. In Arctic region, seasonal freezing/thawing processes, cryohydration leading type weathering. Soils different-aged islands Lena River Delta were investigated. Thin sections analyzed using polarizing microscope Leica DM750P (Leica Camera AG, Wetzlar, Germany...

Fourier transform infrared spectrometer (FTIS) and polarizing microscope are utilized to analyze the water molecule content in gas-liquid inclusions quartz sand micro-morphology change laws of before after microwave heating. The experimental results show that when is heated 600℃ under microwave, cracks or micro-cracks appear at interface, which causes (OH)-water crystal lattice into smaller liq...

Abstract Murals of Cave 256, Mogao Grottoes consist several layers, with the outermost layer overlays all others. The bottom was painted in five dynasties. mural Song Dynasty. Statues were repainted Qing We found that different blue pigments are used multilayer murals which reflects social development at time to a certain extent. In order know type pigments, technology such as X-ray diffraction...
