The data focused on the value of immunofluorescence on paraffin-embedded sections are controversial, and it is still difficult to obtain reproducible results. The aim of our study was to evaluate the usefulness of immunofluorescence on paraffin-embedded renal section in detecting immune complex deposits in IgA nephropathy (n = 24), membranous glomerulopathy (n = 22) and lupus nephritis (n = 24)...

Riga Technical University, Institute of Technical Physics, Azenes Str. 14-322, LV-1007 Riga, Latvia E-mail: [email protected] In our previous research, the polyisoprene-nanostructured carbon composite (PNCC) has been approved as a promising material to be used as a low-pressure sensor. The main advantage of PNCC is its hyperelastic flexibility as compared with conventional piezo-ceramic pr...

The final stages in the total synthesis of vitamin B12 are reported. It was particularly appropriate, I think, and most pleasant for us this morning to see the splendid film provided by our Russian friends, in which the very successful Symposium at Riga was enshrined for posterity. Appropriate in the sense, from my own point of view, that I did report there at Riga, on the progress we had made ...

Numerous techniques in designing zones happen at high temperature and functions under high temperature are in a way that involves non-linear radiation. In weakly conducting fluids, however, the currents induced by an external magnetic field alone are too small, and an external electric field must be applied to achieve an efficient flow control. Gailitis and Lielausis, devised Riga plate to gene...
