“probably not significant”

However, the differences ob- served are probably not significant since the gen- eral trend in both sets of measurements not only tended toward a sharp decrease in the earliest stages, but included a gradual decrease in the later stages.

Protein Synthesis in Cellular and Syncytial Trophoblast 407 TABLE V Incubation Time 5 min Pulse 20 min Pulse 40 min Pulse 20 min Chase 40 min Chase 4 h Chase X2* 11* 21* 22* 17* 9* 35* Degrees of Freedom 10 11 11 11 11 10 Table V presenting the results of the chi-squared analysis of the grain data for cytotrophoblast. The high value at 4 h is probably not significant in light of the high standard error.

This density is slightly lower than the average density of wild-type mitochondrial large subunits at 25 mM Mg+a,but the difference is probably not significant.

The diacetylated isoform is acetylated at lysines 16, 12, or 8 (the apparent drop in acetylation at Lys 16 in the diacetylatedisoform is probably not significant) while acety- lation of Lys 5 remains low.

We consider that this is probably not significant, although a detailed statistical analysis is beyond the scope of this paper.

We found that the binding of CQ to FPIX in ghost membranes is sensitive to buffer pH, but this effect is probably not significant across the range of reported cytosolic pHs (Fig. 5 A).

The small difference in ~c~, is probably not significant.

A slight inhibitory action by 100 units and 10 units of peni- ciUin is suggested, but the differences between these two groups and the control group are probably not significant.

Submucous hemorrhages and edema of the urinary bladder, also are probably not significant.

The differences in yield are probably not significant, since the packed-cell method is subject to large error.

While most of the differences in plating efficiencies shown are probably not significant, some, like that of Appendix A1 in 10 per cent porcine serum, suggest definite differences in nutritional requirements.

Tested in polystyrene tubes, the dotting time was 65 min in the presence of C'I esterase inhibitor and 85 min in the presence of buffer, a difference which was probably not significant but may 322 SERUN[ ctl ESTERASE INHIBITOR have reflected contamination of the C'I esterase inhibitor preparation with traces of a procoagulant substance.

During the first 7 days, no signs of infection were found in the CNS in 84 per cent of the animals examined, and in the remainder such lesions as were found were probably not significant.

The median values obtained with BMC were roughly half of the foregoing but the overlap on day 7 suggests that the differences are probably not significant.

This differ- ence in the amount incorporated by the two groups is probably not significant since it is likely that some of the labelled red cells in the anemic animals were hemolyzed as soon as they were released into the circulation. 164 IRON METABOLISM IN SWINE WITH ANEMIA The average amount of iron incorporated into red cells daily by the anemic animals was 4.23 mg./kg, of body weight, a value 4.2 times the normal mean.

A slight bt~t probably not significant inhibition of homing to mesenteric nodes was found when cells were incubated with plasma obtained either 2 or 24 hr after injection of BPCS.

This is probably not significant.

Column 3 thus represents values of pigment density of a primary leaf. It can be seen that the concentration of carotenoid pigment increases sig- nificantly with age, but that the increase in protochlorophyll concentration is small and probably not significant.

The difference in photoreversal between fed and unfed animals is probably not significant, although the advantage always lies with the fed animals except when the dosage of photoreversing light is low. 4.

There was slight, but probably not significant, diminution of inflammation during saline administration.

The small increase in AI between days 9 and 11 is probably not significant; in other experiments we have found that after 12 d the AI is always between 1 and 2.

The small differences observed among the three groups of cells are probably not significant since the nature of the experiment was such that each cell group was run independently, necessitating a separate dilution of enzyme for each.

The difference between these time constants is probably not significant.

12. There is a slight suppression in the peak magnitude of the inward current which is probably not significant.

[ 81 ] pointed out that small morphological adaptations also occur during this time interval, although they are probably not significant for strength gain due to the lack of androgenic hormone production.
