It has often been hypothesized that smaller particles (≤ 2.5 μm; PM2.5) have the greatest health impacts because they penetrate deep into the alveolar regions of the lung and are highly reactive (Brook et al. 2004).
It can be hypothesized that small molecules which have been previously shown to induce proliferation in differentiated mammalian cells, such as cardiomyocytes, could be combined with myotube fragmentation compounds to achieve cellularization.
It can also be hypothesized that small CNTs but not large CNTs enter the bloodstream to some extent.
In this study, it was hypothesized that small clusters would act to relay Ca2+ release to neighbouring clusters and that this was particularly important in gaining critical mass for the initiation of a Ca2+ wave.
Although it may be hypothesized that small amounts of tobramycin always leak into the circulation and that blood concentrations only rise in patients with some kidney injury, this is likely not the case, because in 17% of the patients tobramycin was never detected in the blood despite using an extremely sensitive detection method.
Given that these anatomical structures increase in size with increasing complexity of function, it can be hypothesized that smaller modifications may be more evident in the posterior visual pathway.
Therefore, it was hypothesized that: H1.
It has previously been hypothesized that the difference between (small) teleost and (large) tetrapod T2R and V1R repertoires might reflect an adaptation to the terrestrial lifestyle [ 11].
Cas proteins share functional similarity with proteins involved in eukaryotic RNA interference systems and, hence, it has been hypothesized that spacers function analogously to small interfering RNAs (Makarova et al., 2006).
In D. Melanogaster, CYP303A1 has a putative external sensory development function and it has been hypothesized that it probably metabolizes a small signal molecule essential in the development and structure of external sensory organs [ 30, 76].
