Plasma cell disorders are important in the differential diagnosis of acute kidney injury and of renal impairment with proteinuria. One or more of several mechanisms can be involved, such as cast nephropathy, deposition of monoclonal immunoglobulins, formation of amyloid fibrils, hypercalcaemia, hyperuricaemia and a variety of tubular syndromes. Various tests, such as serum electrophoresis and i...

Working under the assumption that hormesis is triggered by specific types of DNA damage, this report focuses on the types of damage which form the signature of ionizing radiation. The key attribute of the signature is the clustering of damage, arising from clusters of energy deposition such that more than one site within a 10 base pair segment of DNA has been chemically altered. A brief overvie...

A miniaturized surface plasmon resonance sensor has been used as an on-line detector for capillary electrophoresis separations. The capillary was modified slightly to shield the sensor electronics from the high voltages applied during the separation. A three-component mixture of high refractive index materials was separated and detected at the millimolar level by an untreated gold-sensing surfa...

Grassland management regimens influence the structure of archaeal communities in upland pasture soils, which appear to be dominated by as yet uncultivated non-thermophilic Crenarchaeota. In an attempt to determine which grassland management factors select for particular crenarchaeal community structures, soil microcosm experiments were performed examining the effect of increased pH, application...

An on-column metal coating procedure was developed for sheathless electrospray emitters, based on Justus von Liebig's electroless silver mirror reaction followed by electrochemical deposition of gold onto the silver layer. The coating procedure is straightforward, mild, inexpensive, and can be performed with standard laboratory equipment. A long-term (600 h) stability investigation of the condu...

Waldenström's macroglobulinemia is a distinct clinicopathologic entity defined as a B-cell neoplasm characterized by lymphoplasmacytic infiltrate in the bone marrow, with an associated immunoglobulin (Ig) M paraprotein. Clinical manifestations are due to deposition of IgM in the liver, spleen, and/or lymph nodes, so it presents with anemia, hyperviscosity, lymphadenopathy, hepatomegaly, splenom...

The sugarcane in Brazil is passing through a management transition that is leading to the abolition of pre-harvest burning. Without burning, large amounts of sugarcane trash is generated, and there is a discussion regarding the utilization of this biomass in the industry versus keeping it in the field to improve soil quality. To study the effects of the trash removal on soil quality, we establi...

sites on the polysaccharide using simple sugars as prospective inhibitors. Although much discussion is given to this topic, a really critical evaluation of the method as it is applied would have been welcome. As if overcome by long hours of work in purifying and assaying, the members of the conference several times lapse into rather unrewarding philosophical speculation on the question of wheth...
