Negative correlations are consistent with the expected, faster degradation of target mRNAs, whereas positive correlations denote the existence of feed-forward regulations mediated by transcription factors.
A variety of more recent findings obtained with voltage sensitive dyes emphasize the existence of feed-forward, excitatory processes in V1 and complex feedback activation processes between V1 and 'higher' cortical regions.
A new study finds that yellow-breasted buntings (Emberiza aureola) are being hunted out of existence to feed Chinese appetites for the songbird, The Guardian reports.
Moreover, the Shire Highlands area (a plateau in southern Malawi, located east of the Shire River) is particularly suitable for dairy production because of its close proximity to Blantyre, the existence of good feed resources, a favourable climate and being relatively free of livestock diseases.
Satiety feelings appear as a response to ingested food, and there is good evidence supporting the existence of physiological feed back systems referred to as ileal brake, which sense the presence of nutrients in the gastrointestinal system in order to regulate appetite [ 9– 11].
This study sought to investigate the availability of camel drought feeds in the study site, guided by two specific objectives: to establish the existence of supplementary feeds used by the Borana community for camels during the drought periods and to establish the distribution of the supplementary feeds.
The study was guided by these objectives: to establish the existence of supplementary feeds used by the Borana community for camels during drought periods and also to establish the distribution of the supplementary feeds.
Therefore, in many respects psoriasis represents a proliferative wound response failing to terminate, suggesting the existence of molecular feed-forward circuits fuelling a vicious circle.
UNICEF partners on the ground are educating the population about the existence of the feeding centers and encouraging all families with malnourished children to seek treatment.
More importantly, in the same study the authors suggested the existence of a feed-forward mechanism, by which amyloid deposition promotes further amyloid deposition.
Interestingly, blocking the VEGF pathways with sunitinib decreased the expression of ER stress-related genes and VEGFA, indicating the possible existence of a feed-forward mechanism between VEGF and HIF1α/ER stress pathways.
