Its formation and limited lifespan is critical for fertility, as luteal-derived progesterone is the essential steroid hormone required for embryo implantation and maintenance of intra-uterine pregnancy until the placenta develops.
If deforestation alters the distribution of adaptive variation along ecological gradients important to the generation and maintenance of intra-specific diversity, it could eventually constrain future evolutionary responses to new environmental conditions.
Social learning is by definition the essential mechanism for the formation of traditions, as it is necessary for diffusion and maintenance of intra-group specific behaviours.
However, we observed no beneficial effect of E2 treatment on the maintenance of intra-islet endothelial cell population (ESM Fig. 4).
Our study provides some of the first empirical evidence for NFDS on female fecundity in natural conditions and as such provides an important key to understanding the maintenance of intra-sexual phenotypic and genetic variation in this species.
Hemodynamically-mediated renal failure arises when mechanisms of maintenance of intra-glomerular pressure are impaired, e.g. decrease in blood flow to the kidney, vasoconstriction of glomerular afferent arteriolar, or vasodilatation of glomerular efferent arterioles.
It may, therefore, be hypothesised that, with regard to the long-term stability of orthodontic treatment results achieved, orthodontic therapies may be more efficient if they are accompanied by additional training of the maintenance of physiological intra-oral pressure phases [ 40].
In compliance with the results of our previous study, no specific neural correlates involved in the maintenance of the intrinsic intra-item binding condition were observed.
(A ) Schematic diagram showing the genetic set-up to examine cell shape maintenance by intra- and inter-protofilament mutants of MreB.
However, when the MTL is important for the binding of non-overlapping neural representations, one would expect the MTL to be activated during the maintenance of both the extrinsic intra-item and the inter-item binding condition.
For maintenance of oral health, accurate intra-oral clinical and radiographic evaluations are required for patients with this syndrome in order to provide an early diagnosis of other abnormalities involving the primary and permanent dentitions.
