Ito specimen. The application of this highly specific multiplex realtime PCR assay in larger and prospective studies will allow a better appreciation of the intensity of transmission and the knowledge of the movement of different Plasmodium species in the malaria vectors in Africa. This technique could facilitate the implementation of more basic research to address the fitness cost associated with Plasmodium spp infections on several life history traits including survival, behavioral and reproductive capacity of mosquito vectors.AcknowledgmentsPlasmodium genomic DNAs of P. vivax, P. malariae or P. ovale and plasmids containing insert of the 18S gene of each of those species were kindly provided by Dr Stephanie Yanow at the Provincial Laboratory for Public Health, Edmonton, Alberta, Canada.

Circular Dichroism (CD) spectroscopy is a highly utilized method for the investigation of protein structure [1]. In the near-UV region (240?20 nm) the method is used to identify delicate structural SMER28 changes related to the orientation of the protein aromatic and disulfide amino-acids side chains, which might be a result of their interactions with ligands and mutations. In the farUV region (190?40 nm) the 23977191 method is used to characterize changes in the secondary structure of proteins. The aromatic side chain chromophores, such as tryptophans and tyrosines, have the greatest contribution to the near-UV region of the CD spectra but can also contribute to the far-UV intensities [2,3]. The purchase 57773-63-4 fundamental molecular unit 
of CD is the Rotational Strength which is defined as the imaginary part of the scalar product between the electric and magnetic transition dipole moments [4]. Most protein chromophores, however, including the aromatic ones, are not intrinsically chiral, contain elements of mirror symmetry and therefore have zero rotational strengths and no CD spectrum. Within the protein environment these chromophores become chirally perturbed and generate rotational strengths by three mechanisms [5] namely: i) the one-electron mechanism (intrachromophore mixing) – mixing of electrically and magnetically allowed transition moments within the same chromophore; ii) the m- m mechanism – coupling between electrically allowed transitions in two separate chromophores; and iii) the m-m mechanism – couplingbetween electrically and magnetically allowed transitions in two separate chromophores. The last two are also known as coupledoscillator type (inter-chromophore mixings) mechanisms to reflect that the interactions are between two different chromophores. Despite the huge amount of data available on protein structures and the increased implementation of CD, the contributions of the aromatic side chains have not yet been entirely revealed. Such knowledge would explains effects of mutations, alterations in the local protein structure, characterization of reaction.Ito specimen.
