Abnormal regulation that produces a deficiency of the amines appears to be associated with depression, and an excess of amines is associated with mania.
The recN mutation produced a partial deficiency in the repair of double-strand breaks, while the recJ mutation produced a deficiency in the repair of daughter-strand gaps in uvrB recB cells (but not in uvrB cells), and a deficiency in the repair of both daughter-strand gaps and double-strand breaks in uvrA recBC sbcBC cells.
However, before concluding a definite role for mast cells from our experimental data, it should be noted that MCDM carry a spontaneous mutation for tyrosine kinase receptor c-kit which not only produces a deficiency of mast cells but may have an independent effect on the function of sensory neurons, which are known to express it [ 35].
This could be related with the time needed in vivo for producing a B12 deficiency in transfected tissue, as a function of the existing store of B12 in brain [8].
According to the "folate-trap hypothesis", cobalamin deficiency results in 'trapping' of tetrahydrofolate, producing a functional folate deficiency that leads to impaired erythropoiesis and DNA biosynthesis [ 7].
The results are consistent with copper limitation producing a secondary iron deficiency that negatively impacts respiratory growth, and with the vacuole playing a vital role in regulating intracellular copper levels.
Cigarette smoking may decrease folate in plasma and produce a localized deficiency of folic acid.
Dkk1b induction decreased nuclear-localized β-catenin and produced a pronounced deficiency in Runx2+ preosteoblasts, consistent with Dkk1b being a potent BMP-dependent inhibitor of osteoblast progenitor renewal.
Therefore, despite the absence of (i) weight loss, (ii) mucus in the airways, and (iii) fibrosis, four days of 90% oxygen treatment of newborn mice is sufficient to produce a chronic deficiency in alveolarization.
Generally, writing programs are no more harmful than patronage has been through the centuries, and their chief deficiency — producing a uniform sort of competence — is too well known to require further warning from me.
The locus coeruleus produces norepinephrine, a deficiency of which causes both memory disturbance and psychological symptoms.
