metal oxides play a very important role in many areas of chemistry, physics and materials science.the metal elements are able to form a large diversity of oxide compounds. in this investigation, wesynthesis sno2 and c,n,s-tridoped sno2 nanoparticles by precipitation method. the synthesizedsno2 and c,n,s-tridoped sno2 nanoparticles were characterized by instrumental analysis methods,such as x-ra...

A 51 year old man developed progressive cranial and proximal muscle weakness, hyperreflexia and mental change. The disorder progressed over 9 days following the fifth weekly spraying with the organophosphate (OP) insecticide, phosmet, with limited symptoms of acute toxicity. Marked decremental responses of 50-80% on slow and fast rates of stimulation were improved to 15% by edrophonium or neost...

Using the mouse passive transfer model, the effects of purified human myasthenic immunoglobulin G and of the monovalent Fab fragment on neuromuscular junctions were investigated. Treatment with IgG markedly reduced amplitudes of miniature endplate potentials. When Fab fragments were transferred alone or with subsequent addition of IgG no neuromuscular transmission block was induced. Myasthentic...

Sensory neurons of Hirudo medicinalis were cultivated on patterns of extracellular matrix (ECM) protein which were prepared by UV irradiation using copper grid masks. The relation of the patterns and of the outgrowth of neurites was observed by scanning electronmicroscopy after gold decoration. The neurites were guided by narrow (10 microM) lanes of ECM protein. Branching of neurites was induce...

Nephrotic syndrome has been observed in association with different types of neoplasia. This appears to be the first report of the occurrence of the nephrotic syndrome due to membrano proliferative glomerulonephritis in association with carcinoma of the oesophagus. Although proteinuria was present before excision of the tumour, the nephrotic phase occurred subsequently. Eventually it disappeared...

The sequential cytological changes which develop in tissue culture cells infected with adenovirus types 5 and 7 are described and compared with those produced by adenovirus types 1, 2, 3, and 4. The evidence that is presented indicates that types 1, 2, and 5 belong to one major subdivision of the adenovirus group and types 3, 4, and 7 to another. That the host cell nucleus is the principal site...

The paper presents the possibility of 3-D reconstruction of the florid plaques obtained in Transmission ElectronMicroscopy. The TEM images registration process is quite different from Nuclear Magnetic Resonance and Computed Tomography on account to increasing amount of the image size and resolution together. The normalisation of image brightness and contrast, produced by differences in slices t...
