Antiviral proteins (AVP), present in silkworm fecal matter, show activity against nuclear polyhedrosis virus (NPV) in vitro and in vivo. The extract of silkworm fecal matter prepared in phosphate buffer solution of pH 7.5 was subjected to 50% solid ammonium sulfate precipitation to enrich AVP, then which was dialyzed. The dialysate was applied to the column containing silica gel-G, the column e...

development of a stool antigen immunoassay to detect helicobacter pylori infection requires monoclonal antibody against the specific antigen. alkylhydroperoxide reductase (ahpc) of helicobacter pylori has been described as a specific and unique enzyme for h. pylori and therefore, both h. pylori ahpc and anti-ahpc could be useful in the development of serologic and stool antigen tests, for detec...

The special application of iron-manganese oxide nanocatalysts has been investigated in decomposition of hydrogen peroxide. In this research, iron-manganese oxide nanocomposites were synthesized by co-precipitation, sol-gel and mechanochemical methods using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared on the variou...

Fructan-hydrolyzing enzyme from Streptococcus salivarius KTA-19 isolated from human dental plaque was investigated. The enzyme was purified by ammonium sulfate precipitation, acetone fractionation, and column chromatography on Bio-Gel and DEAE-cellulose. The purified enzyme showed a single band on sodium dodecyl sulfate-polyacrylamide gel electrophoresis and isoelectric focusing. Its molecular ...

A colony-stimulating factor (CSF) that stimulated human and mouse bone marrow cells to proliferate in vitro and form pure granuloid colonies was purified about 4000-fold from normal human urine. Purification procedures included concentration with polyethyleneglycol, ammonium sulfate precipitation, two chromatographic separations on DEAE-cellulose columns, gel filtration, and polyacrylamide gel ...

After being envenomated by the timber rattlesnake. a patient was found to have a platelet count of 5000 per tl. prothrombin time and activated partial thromboplastin time both greater than 1 50 sec. plasma fibrinogen 0 mg/dl. and fibrinogen split products 2560 sg/ml. However. this patient did not appear to have acute disseminated intravascular coagulation since coagulation factors II-XIl were n...
