” "H-null," or "H-zero"). Asignificance testis used to determine the likelihood that the results supporting the null hypothesis are not due to chance. A confidence level of 95% or 99% is common. Keep in mind, even if the confidence level is high, there is...

Neutral Theory: The Null Hypothesis of Molecular Evolution The most important contribution of Kimura's work is that it provides a theoretical framework for developing methods that detect the action of selection within genomes. However, to be able to demonstrate that a sequence is subject toselective...
To test our hypothesis, we analyzed neurogenesis in the hippocampal Laser Scanning Confocal Immunofluorescence Microscopy DG, as well as neuropathology and behaviors, of fosB- Free-floating sections were subjected to immunofluores- null and fosBd/d mice. We show that fosB-null mice cence microscopy...
In all analyses, the null hypothesis was rejected at the 0.05 level. (*), (**), and (***) indicates P ≤ 0.05, P ≤ 0.01, and P ≤ 0.001, respectively.Abbreviations DOPAC: 3,4-dihydroxyphenylacetic acid 3-MT: 3-methoxy-tyramine 5-HIAA: 5-hydroxy-indole-acetic acid COMT: ...
In 1961, Mary Lyon proposed the inactive-X hypothesis to explain what happens to genes on the Barr body. She hypothesized that (1) the genes found on the condensed X chromosome are genetically inactive, (2) inactivation occurs very early in development during the blastocyst stage, and (3) ...
However, a study of bone marrow-derived macrophages infected with E. coli appears to support the hypothesis that PrPC may have roles in phagocytosis, phagosome maturation, cytokine expression, and macrophage microbicidal activity, given that E. coli lacks the natural SIRPα partner CD47 (Wang et ...
