A tractor-mounted mechanized applicator was developed for large-scale deployment of paraffin-wax dispensers of pheromone for mating disruption of oriental fruit moth, Grapholita molesta (Busck). The wax formulation was mostly water and emulsified paraffin wax containing 5% (by weight) pheromone [93:6:1 blend of (Z)-8-dodecen-1-yl-acetate:(E)-8-dodecen-1-yl-acetate: (Z)-8-dodecen-1-ol]. Ten mill...

Human prion diseases like Creutzfeldt-Jakob disease are infectious, inherited, or sporadic neurodegenerative disorders, characterized by the accumulation of an abnormal isoform of the host-encoded prion protein. This affects nervous tissue in sporadic Creutzfeldt-Jakob disease and, additionally, in lymphoid tissue in bovine spongiform encephalopathy-linked variant Creutzfeldt-Jakob disease. Exp...

An autopsy study was conducted on patients with Alzheimer's disease in order to explore the possibility of amyloid beta-protein deposits in tissues other than the brain. Immunoperoxidase staining techniques were employed using an amyloid beta-protein antiserum as primary antibody; paraffin sections of kidney, liver, heart, lung, spleen, bone marrow, colon, stomach, adrenal, thyroid, and brain w...

This describes the sodium sulphate-Alcian Blue (SAB) method for staining amyloid in paraffin sections. Its value lies in the possibility of subsequent counterstaining and thus of revealing the structural relationships of amyloid. In the kidney the topical disposition of amyloid closely resembles the disposition of fibrin in the kidney of diabetics; this suggests that upset in vascular permeabil...

The presence of different immunoglobulins (lgG, IgM, and IgA) was studied in 50 routinely fixed paraffin embedded renal biopsies. lgG deposits was seen independently in 26 (52%) cases, in combination with IgA in 14 (28%) cases, with IgM in 1 (2%) case and with both lgA/lgM in 1 (2%) case. lgA alone was seen in 1 (2%) case only. IgM was seen only in 2 (4%) cases. In one case it was seen in combi...

To obtain as much information as possible from light-microscopy about changes in the glomerular basement-membrane, a thin section microtome attachment is necessary in order to produce 1 to 3 micron sections. The most informative staining method of paraffin embedded tissue is the Muller-Mowry-Masson trichrome (M-M-M) combination stain. The deposits, e.g., in systemic lupus erythematosus (SLE), s...

The hand stencils of European Paleolithic art tend to be considered of pre-Magdalenian age and scholars have generally assigned them to the Gravettian period. At El Castillo Cave, application of U-series dating to calcite accretions has established a minimum age of 37,290 years for underlying red hand stencils, implying execution in the earlier part of the Aurignacian if not beforehand. Togethe...
