It has been shown previously that during differentiation, newly generated cells in the OB down-regulate PSA-NCAM and DCX [18], [19].
The 3D pattern becomes visible during sample heating at the temperature some higher than 500 °C; the pronounced 2×1 structure appears, as it has already been shown previously [15, 25], during cooling at the temperature less then 600 °C.
Our result that both retinoic acid and Wnt signaling are disrupted in spt intermediate mesoderm suggests the additional hypotheses that (1) retinoic acid regulates Wnt signaling, or that (2) Wnt regulates retinoic acid signaling; the latter has been shown previously in zebrafish during gastrulation [ 81] and patterning of the neuroectoderm [ 82].
Following the identification of neurotophic and angiogenic factors within degenerate IVDs, the regulation of these factors by key cytokines that have been shown previously to be upregulated during IVD degeneration was investigated to determine the regulation of neurotrophic and angiogenic factors by potential responsive cells within the disc.
The role of TRIM33 as a negative regulator of enhancer activity is reminiscent of LSD1, a histone demethylase that has been shown previously to suppress active enhancers during embryonic stem (ES) cell differentiation (Whyte et al., 2012).
It has been shown previously that identification of transmission routes during an outbreak based on genomic data is likely to be challenging due to high levels of uncertainty (Worby et al. 2014), a finding also reflected in recent investigations (Didelot et al. 2014).
Subjects made comparative size judgments for pairs of stimuli that depicted either the same or different objects; some of the pairs presented during scanning had been shown previously and others were new.
It has been shown previously that B0AT1 is inhibited in villus during chronic intestinal inflammation, whereas SN2/SNAT5 is stimulated in crypt cells [ 9] and treatment with a broad spectrum immune modulator reversed these alterations during chronic intestinal inflammation [ 19].
In addition, it has been shown previously that general fluid intelligence is impaired during hypoglycemia, and it is fluid intelligence rather than crystallized intelligence that is responsible for spatial cognition (10).
