Effects of trimebutine maleate (TM) on intestinal motility in short bowel syndrome (SBS) were studied in conscious canines in both acute and chronic phases following 80% massive distal small bowel resection (MSBR). TM was administered orally to beagles with MSBR or as controls in the postprandial and fasting states, and given simultaneously with meals. Intestinal motility was measured using bip...

Homologous recombination contributes both to the generation of allelic diversity and to the preservation of genetic information. In plants, a lack of suitable experimental material has prevented studies of the regulatory and enzymatic aspects of recombination in somatic and meiotic cells. We have isolated nine Arabidopsis thaliana mutants hypersensitive to x-ray irradiation (xrs) and examined t...

Discontinuously reinforced aluminum metal matrix composites (MMCs) with about 20 vol.% reinforcement produced by powder metallurgy (PM) are attractive for many structural applications because of their high specific strength and stiffness. While they exhibit reduced ductility and toughness at room temperature, many of them can be superplastically deformed at high-strain rates in the vicinity of ...

To evaluate intestinal motility after 80% massive distal small bowel resection (MSBR), we continuously monitored interdigestive and postprandial bowel motility using bipolar electrodes and/or contractile strain gage force transducers in conscious beagle dogs before, and at 0-4 weeks and 8-13 months after the surgery. Fasting duodenal migrating myoelectric (or motor) complexes (MMCs) occurred at...

Although SHIP is a well-established suppressor of IgE plus Ag-induced degranulation and cytokine production in bone marrow-derived mast cells (BMMCs), little is known about its role in connective tissue (CTMCs) or mucosal (MMCs) mast cells. In this study, we compared SHIP's role in the development as well as the IgE plus Ag and TLR-induced activation of CTMCs, MMCs, and BMMCs and found that SHI...

In composites, outstanding properties of two materials can be combined. particular, metal–matrix composites (MMCs) combine the a high-strength ductile metallic matrix with special embedded ceramic particles. This hybrid used to create functional material. However, during consolidation, thermal load most common MMC-processing routes is an obstacle for such functionalization, because unique phase...

Mechanical spectroscopy has been used for studying the relaxation of the mechanical and thermal stresses, which are built at the fibre-matrix interfaces in AICu-A1203 Metal Matrix Composites (MMCs). The interface strength has been evaluated by the stress dependent damping which exhibits a peak of solid friction. This peak is interpreted as due to interface microcracking. Relaxation of thermal s...

Coand Fe-based alloys produced by powder technology are being widely used as a matrix for diamond-containing composites in cutting, drilling, grinding pplications, etc. The severe service conditions demand that the mechanical and tribological properties of these alloys be improved. Development of metal-matrix composites (MMCs) and alloys reinforced with nanoparticles is a promising way to resol...

In recent years, with the rise of electric vehicle industry, there has been significant research on charging and power supply technologies for vehicles. terms corresponding converter usage, modular multi-level converters (MMCs) are also increasingly used in field because their unique advantages. However, circulating current problem MMCs not effectively addressed existing domestic international ...

Composite material is a combination of two or more materials having compositional variations and depicting properties distinctively different from those of the individual materials of the composite. A composite mixture having more than one fiber is known as hybrid composite During the past decade, considerable research effort has been directed towards the development of in situ Metal Matrices h...
