Elderly humans have altered cellular redox levels and dysregulated immune responses, both of which are key events underlying the progression of chronic degenerative diseases of ageing, such as atherosclerosis and Alzeimer's disease. Poorly maintained cellular redox levels lead to elevated activation of nuclear transcription factors such as NFkB and AP-1.(More)
A simple, precise, accurate and rapid high performance thin layer chromatographic method has been developed and validated for the determination of clotrimazole in bulk drug and tablet dosage form. The stationary phase used was precoated silica gel 60F(254). The mobile phase used was a mixture of cyclohexane:toluene:methanol:triethyleamine (8:2:0.5:0.2(More)
A label-free method for determining the 5'-end cap identity and orientation of a messenger RNA (mRNA) is described. Biotin-tagged probes that were complementary to the 5' end of target mRNA were used with RNase H to cleave the 5' end of the mRNA. The cleaved end sequence was isolated using streptavidin-coated magnetic beads and then analyzed by LC-MS.(More)
Small interfering RNA (siRNA) is a novel therapeutic modality that benefits from nanoparticle mediated delivery. The most clinically advanced siRNA-containing nanoparticles are polymer-coated supramolecular assemblies of siRNA and lipids (lipid nanoparticles or LNPs), which protect the siRNA from nucleases, modulate pharmacokinetics of the siRNA, and enable(More)
RMP-7 is a bradykinin analogue containing all "L" amino acids and a reduced dipeptide bond between amino acids eight and nine. This reduced dipeptide bond [4-Me-Tyr-psi(CH2NH)-Arg] is created under synthetic conditions which could result in inversions of the chiral centers of either 4-Me-Tyr or Arg. Stereoisomers of RMP-7 would be expected to have altered(More)
