R. parkeri is the newest member of the SFG rickettsiae in the Western Hemisphere to be conclusively associated with illness in humans (12 ).
None of the theorized negative reactions were reported at greater incidence than would be expected in the general population, and could not be conclusively associated with the treatment.
We are now confirming that in our study, no specific molecular types could be conclusively associated with maternal-fetal cases, gender, age group or presence/absence of underlying conditions, except for the seven isolates 4b/CC6/ECII belonging to cluster 7 and the isolates grouped in cluster 11.
No nucleic acid has been conclusively associated with infectivity; agent is resistant to ultraviolet radiation and nucleases.
Evidence in favor of a protein-only hypothesis includes: No virus particles, bacteria, or fungi have been conclusively associated with prion diseases, although Saccharomyces cerevisiae has been known to be associated with infectious, yet non-lethal prions, such as Sup35p.
For example, exposure to lead measured in blood has been conclusively associated with diminution of cognitive abilities in children (Needleman et al. 1990).
Mutations in the KRAS and TP53 genes have been detected in animal models human tumors linked to asbestos exposure, although these alterations have not been conclusively associated with asbestos exposure Nelson, 1999 #387, [ 109, 110].
However, to date no single set of virulence determinants has been conclusively associated with invasive nontypeable strains (19 – 219).
To date, no specific dietary factor or nutrient has been conclusively associated with the risk of pancreatic cancer (WCRF/AICR, 2009).
In particular Gelen et al. demonstrated that p27Kip1 expression is correlated to RFS [ 31]. p27Kip1 loss has not been conclusively associated with biological aggressiveness of GIST, and is not used as a predictor of survival [ 15, 17, 18].
