crude glycerol (cg) is an abundantly available and cheap by-product from biodiesel production. value-added applications for cg are highly wanted by industry and several processes such as the use of cg for enhanced oil recovery have been proposed. the aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (srb) indigenous to oil reservoirs using cg as substrate. th...

Ricin is a type II ribosome inactivating protein (RIP) isolated from castor beans. Its high toxicity classifies it as a possible biological weapon. On the other hand, ricin linked to specific monoclonal antibodies or used in other conjugates has powerful medical applications. Ricin consists of an A-chain (RTA) that damages ribosomes and inhibits protein synthesis, and a B-chain that plays a rol...

For almost a full decade now, the Java community has struggled with the Object/Relational impedance mismatch, a fundamental problem for those who would seek to store rich domain objects into a relational database. While this problem is not unique to Java—C++ developers wrestled with the problem long before Java was available, and .NET developers are just beginning to discover the depths of the ...

Ricin, a plant-derived toxin originating from the seeds of Ricinus communis (castor beans), is one of the most lethal toxins known, particularly if inhaled. Ricin is considered a potential biological threat agent due to its high availability and ease of production. The clinical manifestation of pulmonary ricin intoxication in animal models is closely related to acute respiratory distress syndro...

Ricin is a type II ribosome-inactivating toxin that catalytically inactivates ribosomes ultimately leading to cell death. The toxicity of ricin along with the prevalence of castor beans (its natural source) has led to its increased notoriety and incidences of nefarious use. Despite these concerns, there are no licensed therapies available for treating ricin intoxication. Here, we describe the d...

Glyoxysome, endoplasmic reticulum, mitochondria, and proplastid fractions were isolated from endosperm of castor beans (Ricinus communis) germinated for 5 days at 30 C. Samples from sucrose density gradients were diluted with 0.15 m KCI and the membranes pelleted. Lipid extracts of these membranes were analyzed for phosphoglyceride, acyl lipid, and sterol content. The endoplasmic reticulum cont...

Structural changes in endosperm cells of germinating castor beans were examined and complemented with a cytochemical analysis of staining with diaminobenzidine (DAB). Deposition of oxidized DAB occurred only in microbodies due to the presence of catalase, and in cell walls associated with peroxidase activity. Seedling development paralleled the disappearance of spherosomes (lipid bodies) and ma...

Aikpokpodion PE, Dongo LN (2010) Effects of fermentation intensity on polyphenols and antioxidant capacity of cocoa beans. Int. J. Sustain. Crop Prod. 5(4), 66-70. Cocoa beans were fermented for 1 day, 2 days, 3 days up to 6 days. Result showed that, polyphenols content of the fermented beans dropped from 16.11% on day 0 to 6.01% on day 6. The antioxidant capacity also dropped from 96% (IP) on ...

sena-graph syrup has recently been formulated by an iranian pharmaceutical company for being used in bowel evacuation before radiography, colonoscopy and surgery. this study compares the efficacy, adverse effects and patient compliance of two bowel preparation regimens with castor oil and sena-graph syrup in of outpatients for intravenous urography (ivu). one hundred and fourteen consecutive ou...

Temporal patterning is an important aspect of embryonic development, but the underlying molecular mechanisms are not well understood. Drosophila neuroblasts are an excellent model for studying temporal identity: they sequentially express four genes (hunchback --> Kruppel --> pdm1 --> castor) whose temporal regulation is essential for generating neuronal diversity. Here we show that hunchback --...
