Over a period of nine months, 96 CHWs were trained to a level of competence adequate to support the subsequent community demonstration study that was the main objective of this program [ 16].
Given that this was a demonstration study and that the sample represented the majority of the disciplines at the LTC facilities, feedback provided valuable insight on the impact of the APPE on staff.
A small demonstration study shows that detection rates varied from 17%to80%0% across the different surveillance systems.
Based on the demonstration in preclinical studies that thiazolidinediones stimulate epithelial sodium channels in the renal collecting duct [ 10, 11], it has been suggested that thiazolidinedione-related fluid retention in humans is caused by primary renal mechanisms, although a recent preclinical study showed opposing results [ 12] and human experimental data are lacking.
The recent demonstration (in simulation studies) that high concentration of RNA would have been readily attainable in networks of inorganic compartments at hydrothermal vents [ 44] has added credibility to the notion that that recombination and fusion of RNA molecules could have played a major role even in pre-biological evolution [ 45, 46].
And as with glucans or endotoxins, even prior demonstration in many studies that a substance causes inflammation does not implicate it as consistently harmful, because both glucans and endotoxins have also demonstrated health-protective associations (Douwes et al. 2006; Iossifova et al. 2007).
That is why we talk about a demonstration study research design that will of course need replication based on a stronger design at a later point in time, if emerging results are promising.
The strength of the paper is the novel demonstration, through genetic deletion studies, that miR-203 functions as a bona fide tumor suppressor in vivo.
Demonstration of target knockdown: Studies that show that the novel agent is capable of hitting the target molecule in relevant cell line systems are an absolute requirement of drug development (Workman, 2003b).
In line with this is the demonstration in our study that FFA increase the number of early apoptotic cells.
