In line with the third possibility is a recent report suggesting that Nicotiana benthamiana homologues of AtVOZ1, sc4i21 and Ni67, are utilized by plant-adapted rhabdoviruses for cell-to-cell movement (Min et al., 2010).
Because TMPRSS3 is the only gene in this 21q22.3 block, the third possibility is unlikely.
In the first possibility, ck/MyoVIIA directly facilitates extension of the dendritic cap through the epithelial layer.
In the second possibility, elongation of the cap is purely a passive secondary consequence of tension that requires ck/MyoVIIA-mediated anchoring.
In the second possibility, the preferred integration of AA could result from an altered regulation caused by ether lipid deficiency, for example, in the production of diacylglycerol.
Although the present study does not truly discriminate amongst these alternatives, there is merit in the second possibility given the relatively high correlation between 'recurrence time for checking' and 'frequency of checking', and evidence that another measure, path stereotypy, is impacted by both vigor and focus.
In contrast, the second possibility is that aneuploids arise at the same frequency in hybrid meiosis but are more likely than haploids to survive hybrid meiosis; haploid gametes produced by Sk/Sp hybrids may die more frequently than aneuploids.
Because the rate of pneumococcal carriage has not been reported for any age group in Laos, the first possibility remains to be tested, although children 1 16 years of age living in nearby Vietnam have been reported to have a carriage rate of 44%.
In addressing the second possibility i.e. that loss of priming of allogeneic T cells is caused by immunological "ignorance" we hypothesized that we should be able to prevent rejection in recipient mice, who were at high risk of rejection without prior exposure to the antigen.
In support of the second possibility, in patients with single mitochondrial DNA rearrangements or mitochondrial transfer RNA mutations, the respiratory chain deficiency may not affect all enzymes with mitochondrial-encoded subunits (frequently isolated complex I or I+IV defect, Tuppen et al., 2010).
