Plant-based animal feed contains antinutritive agents, necessitating the addition of digestive enzymes in commercial feeds. Enzyme additives are costly because they are currently produced separately from recombinant sources. The coexpression of digestive enzymes in a single recombinant cell system would thus be advantageous. A coexpression system for the extracellular production of phytase and ...

The positive-strand RNA bromoviruses encode two nonstructural proteins, 1a and 2a, involved in RNA-dependent RNA replication. These proteins have extensive sequence similarities with methyltransferase, helicase, and polymerase proteins of other plant and animal viruses. 1a and 2a can also form a complex in vitro. To explore whether 1a-2a interaction is required for RNA replication in vivo, we r...

conclusions: absence of the c allele was significantly associated with failure of response. the presence of c allele was associated with a favorable outcome. afp is a strong baseline predictor of hcv treatment response. a decision tree model is useful for predicting the probability of response to therapy. patients and methods: the study included 263 chronic hcv egyptian patients receiving peg-i...

The new rhodium(I) complexes [Rh(Cl)(COD)(R-NHC-(CH2)3Si(O Pr3)3)] (R = 2,6-diisopropylphenyl (2a); n-butyl (2b)) have been synthesised and fully characterised. The study of their application as ketone hydrosilylation catalysts showed a clear N-substituent effect, 2a being the most active catalyst precursor. Complex 2a has been immobilised in the mesoporous materials MCM-41 and KIT-6. The new h...

In the transformation of multiple genes, gene fusion is an attractive alternative to other methods, including sexual crossing, re-transformation, and co-transformation, among others. The 2A peptide from the foot-and-mouth disease virus (FMDV) causes the co-translational "cleavage" of polyprotein and operates in a wide variety of eukaryotic cells. LP4, a linker peptide that originates from a nat...

It is well established that repeated administration of both 5-hydroxytryptamine(2) (5-HT(2)) receptor agonists and antagonists decreases the density of 5-HT(2A) and 5-HT(2C) receptors. However, the regulation of these two receptors has not been studied in the same tissue. Therefore, we examined the effects of repeated daily injections of the 5-HT(2) receptor agonists (+/-)-2,5-dimethoxy-4-iodoa...
