Glyoxysomes, a form of microbody, are present in castor bean endosperm during the first 8 days of seed germination. They have a "typical" microbody form and are shown histochemically to contain catalase. The catalase label is distributed throughout the microbody and is not an exclusive feature of the crystalline or amorphous core.Castor bean endosperm contain a second cytosome, only slightly la...

castor (ricinus communis l.) is one of the most ancient medicinal oil crops in the world. it has been vastly distributed in different parts of iran. in the present study, the inter simple sequence repeat (issr) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of iran. totally, 16 issr primers amplified 166 loci, of whic...

one of the methods for controlling cucumber root-knot nematode is the use of plant extracts that have nematicidal effect. in this research, sweet wormwood and castor bean were selected and their anti-nematode activity has been investigated against cucumber root-knot nematode (meloidogyne incognita) in laboratory and greenhouse. experiments were carried out by using randomized completely design ...

The effect of the aqueous (aq) seed extract of Aframomum melegueta. K. Schum. (Zingiberaceae) on castor oil-induced diarrhea, intestinal fluid secretion, and gastrointestinal transit was investigated in the study. Castor oil (10 ml/kg, p.o.) induced copious diarrhea in all rats 3 h after treatment. Furthermore, it produced a significant increase in the volume of intestinal fluid secretion in ra...

In January 1999, CERN began to develop CASTOR ("CERN Advanced STORage manager"). This Hierarchical Storage Manager targetted at HEP applications has been in full production at CERN since May 2001. It now contains more than two Petabyte of data in roughly 9 million files. In 2002, 350 Terabytes of data were stored for COMPASS at 45 MB/s and a Data Challenge was run for ALICE in preparation for t...

seeds of the castor bean plant ricinuscommunis l (cb) contain ricin toxin (rt), one of the most poisonous naturally-occurring substances known. ricin toxin, a water-soluble glycoprotein that does not partition into the oil extract, is a ribosome-inactivating toxin composed of two chains, labeled a and b. severity of the toxicity varies depending on the route of exposure to the toxin. inhalation...

background: nowadays colonoscopy has a very important role in screening colorectal cancers. in addition, adequate bowel preparation is critical to colonoscopy, as a poor preparation may obscure pathology or prevent full colonoscopy. as it is estimated that unsuccessful colonoscopy leads to second procedures in up to 20% of patients, we sought to compare the effects of different doses of polyeth...
