In the blowfly Calliphora vicina visual signals are enhanced by amplification and antagonism as they pass from the site of phototransduction in the retina to secondorder neurones (LMCs) in the first optic neuropile, the lamina. The mechanisms responsible for amplification and antagonism were investigated, using currentclamp techniques, to examine the conductance mechanisms generating LMC respon...

The accumulation of kaempferol was evaluated in undifferentiated callus of Tylophora indica through TLC, HPTLC analysis with standard reference compound. Kaempferol is a strong antioxidant and help to prevent oxidative damage to our cells, lipids and DNA. In the present investigation, we have enhanced the kaempferol content in Tylophora indica tissue culture by using precursors like sallicyclic...

We present a multiresolutional algorithm that segments a compound document and uses the results of the segmentation for document enhancement in copier applications. The document is initially segmented into halftone and non-halftone areas. Based on this segmentation the location of the edges due to text, graphics, and images (and not due to halftone dots) are detected on halftone as well as on n...

background: new treatment modalities are developed with the aim of escalating tumor absorbed dose and simultaneously sparing the normal structures. the use of nanotechnology in cancer treatment offers some possibilities including destroying cancer tumors with minimal damage to healthy tissues. zinc oxide nanoparticles (zno nps) are wide band gap semiconductors and seem to have a good effect on ...

the tumors in which odontogenic differentiation is fully expressed are the odontomas. odontomas are considered as hamartomas rather than a true neoplasm. these tumors are composed of enamel, dentine, cementum and pulp tissue. it is most commonly associated with the eruption of the teeth. they are usually discovered on routine radiographic examination. in exceptional cases, the odontoma erupts i...
