The purpose of our review was to delineate a relationship of headache prevalence with the latitude, and we noted a significant relation; the prevalence of headache increased with increasing latitude [1].
Additional cells types associated with inflammation have been identified in the peripheral blood, but fail to delineate a relationship to the local inflammatory milieu [ 5, 10– 13].
Plotting the proportion of positive RDTs at different IFA titers delineates a sigmoidal relationship, with increasing proportions of RDT positivity at titers of ≥1 3,200 (Fig. 1).
The verdict may help to delineate a new relationship between active and former players — positively or otherwise.
Rat brain guanosine binding sites were studied by (i) a pharmacological approach to confirm the hypothesis of the existence of specific G-coupled receptors for guanosine (1) and, for the first time, delineate a structure activity relationship for a series of guanosine derivatives; (ii) a molecular modelling approach to design a pseudo-receptor construction.
Firstly and most importantly, this is a retrospective study presenting with its original caveats and therefore it is hard to delineate a temporal relationship between presence of auto-antibodies and specific clinical, radiological and histopathological phenotypes.
Although a model was identified, additional associations and possible pathways may exist, and further, prospective studies will be necessary to delineate a precise causal relationship.
However, the limited consistency of the epidemiological studies and the difficulty in obtaining consistent exposure response relationships from the studies led a recent comprehensive review to conclude that "human studies fail to raise a convincing conclusion concerning the carcinogenicity of FA and are not helpful to delineate a possible dose response relationship" (Duhayon et al. (2008).
The rotated factors delineate a distinct cluster of relationships, while unrotated factors successively define the most general patterns of relationships in the data.
Taken together, these findings delineate an intricate and complex relationship between stress and alcohol exposure and have stimulated various lines of research that attempt to identify the molecular mechanisms involved in the development of dysphoric symptoms related to the pathophysiology of alcoholism (Koob 2003; Moonat et al. 2010; Pandey 2003).
