Associated with the neuronal plasma membrane are cytoskeletal proteins which probably control the specialization of the membrane into axonal and dendritic domains. Specialized isoforms of the proteins spectrin and ankyrin are located in each region and provide molecular mechanisms for locating specific transmembrane proteins at required points. However, spectrin and ankyrin were defined by exte...

The giant protein titin is the third most abundant protein of vertebrate striated muscle. The titin molecule is >1 μm long and spans half the sarcomere, from the Z-disk to the M-line, and has important roles in sarcomere assembly, elasticity and intracellular signaling. In the A-band of the sarcomere titin is attached to the thick filaments and mainly consists immunoglobulin-like and fibronecti...

Twenty-four Swiss Large White barrows from six litters (four pigs per litter) had either ad libitum (A) or restrictive (R) access to a grower and finisher diet from 20 to 60 and from 60 to 100 kg BW, respectively. Two littermates from both feeding regime were slaughtered at 61 (A60 and R60) or 101 kg BW (A100 and R100). The histochemical properties of myofibers as well as meat quality traits of...

The mutagenicity of PCBs, Aroclor 1242 and Clophen A60 was studied in a mammalian cell assay using V79 Chinese hamster cells as target cells. The method was used as a direct assay without metabolizing cells and as a cell-mediated assay with 5000 R-irradiated rat fibroblasts as metabolizing cells. A wipe soot sample of a PCB fire was studied in the same assay, and the results showed no mutagenic...

The effect of live feed diets containing Brachionus plicatilis (B) and Apocyclops panamensis (A) was investigated on pikeperch larval survival, growth, fatty acid composition in two experiments (E1 E2). Up to six different were provided the larvae, which letters diet names represent organisms as mentioned above subsequent number per larva day. In E1, start cultures with 35 larvae/L supplied (B2...

Objectives: To evaluate a new Modified Anda-TB IgG ELISA test for the serodiagnosis of Mycobacterium tuberculosis in patients and controls. Settings and duration: The study was carried out between January to December 2010 at the Microbiology Department, Umm Al-Qura University, Makkah. Patients and Methods: The Anda IgG and IgM ELISA tests were run on 674 patient’s sera which included 378 active...
