abstract: different techniques have been employed to improve the technological properties of meat. one of the most important techniques is adding proteolytic enzymes which could simultaneously increase the tenderization and solubility of meat proteins. the purpose of this investigation was to study the effect of different levels of the enzyme ficin on ovine and bovine meat and to determine the ...

We describe an immunoassay of digoxin that exploits the differential sedimentation rate between two types of latex particles in a microcentrifugal analyzer. Conventional polystyrene latex particles (relative density = 1.05), sensitized with antibody, are first suspended with the sample and then mixed with digoxin-sensitized latex particles (relative density = 1.5). In the absence of digoxin in ...

The halotolerant bacterial strain BU-4, isolated from a hypersaline environment, was identified as an exopolysaccharide (EPS) producer. Pretreatment liquids of steam-exploded quinoa stalks and enzymatic hydrolysates Curupaú sawdust were evaluated carbon sources for EPS production with the BU-4 strain, produced characterized using FTIR, TGA, SEM. Cultivation performed at 30 °C 48 h, cells separa...

The effect of immunoperoxidase staining and centrifugation on the sensitivity and rapidity of herpes simplex virus detection in mink lung cell cultures was determined with 730 clinical specimens. In standard tube cultures, the use of immunoperoxidase staining resulted in detection of 31 (91%) of 34 positive cultures after overnight incubation, compared with 25 (74%) detected without the stain (...

BACKGROUND Linear acceleration generally gives rise to translation perception. Centripetal acceleration during centrifugation, however, has never been reported giving rise to a radial, inward translation perception. OBJECTIVE To study whether centrifugation can induce a radial translation perception in the absence of visual cues. METHODS To that end, we exposed 12 subjects to a centripetal ...
