The electrocatalytic oxidation of captopril (CAP) was studied by modified carbon nanotubes paste electrode in the presence of isoproterenol (ISPT) using cyclic voltammetry (CV), chronoamperometry and square wave voltammetry (SWV). Also, the values of catalytic rate constant (k), and electron transfer coefficient (α) for CAP were calculated. The mechanism of CA electrochemical behavior at the mo...

seed cap tightness is known to be highly associated with the low germinability of sugar beet fruits. despite, accomplishment of physiological phases of germination in germinating sugar beet seed with a tight cap, seedling emergence is usually suppress by the cap. as the seed coat (including the cap) is originated from ovary wall of the mother plant, seed cap tightness could be considered as one...

Pokeweed antiviral protein (PAP) from Phytolacca americana is a ribosome-inactivating protein (RIP) and an RNA N-glycosidase that removes specific purine residues from the sarcin/ricin loop of large rRNA, arresting protein synthesis at the translocation step. PAP is also a cap-binding protein and is a potent antiviral agent against many plant, animal, and human viruses. To elucidate the mechani...

The effect of chloramphenicol and a proliferation. The inhibition appears to be chloramphenicol analog, thiamphenicol, reversible within a 24-hr period of cellon the growth of bone marrow colonydrug contact. In addition to their effect on forming cells in agar was investigated. At CFC proliferation, CAP and TAP appear to concentrations within therapeutic range, influence the type of CFC differe...

It was shown in [LV] that there are no PL-bundles of the form CPh ↪→ CPh → S where CPh denotes a PL-manifold homotopy equivalent to CP. It was stated at the end of [LV] that the homotopy analog of a) does not exist. In [U], Ucci showed that there exists no Hurewicz fibration of the form CP ↪→ CP → S. However, as stated, this was not the strongest possible result. Let HCP, HCaP and S h denote sp...

Many eukaryotic and viral mRNAs, in which the first transcribed nucleotide is an adenosine, are decorated with a cap-1 structure, (7Me)G5'-ppp5'-A(2'OMe). The positive-sense RNA genomes of flaviviruses (Dengue, West Nile virus) for example show strict conservation of the adenosine. We set out to produce GpppA- and (7Me)GpppA-capped RNA oligonucleotides for non-radioactive mRNA cap methyltransfe...

Decapping of mRNA is a critical step in eukaryotic mRNA turnover, yet the proteins involved in this activity remain elusive in mammals. We identified the human Dcp2 protein (hDcp2) as an enzyme containing intrinsic decapping activity. hDcp2 specifically hydrolyzed methylated capped RNA to release m(7)GDP; however, it did not function on the cap structure alone. hDcp2 is therefore functionally d...
