A polyclonal antibody was used to localize a glycine-rich cell wall protein (GRP 1.8) in French bean hypocotyls with the indirect immunogold method. GRP 1.8 could be localized mainly in the unlignified primary cell walls of the oldest protoxylem elements and also in cell corners of both proto- and metaxylem elements. In addition, GRP 1.8 was detected in phloem using tissue printing. The labeled...

BACKGROUND Endovenous laser ablation (EVLA) is a treatment option for lower extremity varicose veins. In the present study, we investigate to the genetic changes and possibility of living tissue in the saphenous vein wall after the EVLA procedure. METHODS Eleven saphenous vein grafts were randomized in two groups: (1) 4 cm SVG segments of performed EVLA procedure in study group, (2) 4 cm segm...

Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...

BACKGROUND Optical and spectroscopic technologies working at subcellular resolution with quantitative output are required for a deeper understanding of molecular processes and mechanisms in living cells. Such technologies are prerequisite for the realisation of predictive biology at cellular and subcellular level. However, although established in the physical sciences, these techniques are rare...

Environmental contamination by heavy metals is a serious problem due to their incremental accumulation in the food chain. Unlike most organic wastes and the microbial load in aquatic bodies, metal contaminants are not biodegradable, tending to accumulate in living organisms, thus becoming a permanent burden on ecosystems (Bayo, 2012). Most heavy metals are transition elements with incompletely ...

Smithsonian Contributions to Paleobiology, n u m b e r 45, 45 pages, 15 plates, 1982.—Wall textures of 11 species of spinose and quasi-spinose planktonic foraminifera collected in plankton tows from the Nor th and Equator ia l Atlantic have been studied with the scanning electron microscope.

Alternating current measurements have been taken on single Nitella cells over a frequency range from 30 to 2,500,000 cycles per second with the current flow perpendicular to the axis of the cell. The measuring cells were so constructed that electrolytes of any desired concentration could be circulated during the course of the measurements. The cellulose wall which surrounds the cell is found to...

The wall of normal proximal bile duct is occasionally thin with close approximation to the right hepatic artery. Thus, isolation of this hepatic artery can result in excessive weakening of the remnant proximal bile duct wall during hemiliver graft harvest. This type of injury can induce ischemic stricture of the donor common bile duct. This study aimed to review the clinical sequences of such i...
