Subsequently, Oproduced may increase KIF1Bβ protein expression in a positive feedback mechanism. Therefore, ROS and, specifically O, may be critical regulators of KIF1Bβ-mediated apoptosis and its protein expression in neuroblastoma.doi:10.1038/s41598-017-17192-6Clara Angelina...
A positive feedback mechanism between basal-like breast cancer cells and monocytes through STAT3/IL-1β/fibronectin can support chronic inflammation in the... A positive feedback mechanism between basal-like breast cancer cells and monocytes through STAT3/IL-1β/fibronectin can support chronic ...
In Arabidopsis, NCED3 is regulated by a positive feedback mechanism by ABA. In this study in peanut (Arachis hypogaea), we demonstrate that ABA biosynthesis is also controlled by negative feedback regulation, mediated by the inhibitory effect on AhNCED1 transcription of a protein complex between...
The definition of the key cluster of estrogen-sensitive neurons responsible for activating the GnRH neurons to evoke the GnRH surge (and ovulation) should be of substantial value to on-going efforts to understand the molecular and cellular basis of the estrogen positive feedback mechanism. 展开 ...
A potential new target for treatment is the chemotaxis of endothelial monocytes and their adherence to HCMV-infected endothelial cells. Increased CMV infection and adhesion molecule expression, induced by endothelial cell injury, may play a positive feedback role in the regulation of CD14+CD16+ ...
其中的ξ∼0.01M⊙−1为每太阳恒星质量对应的超新星数目(其与恒星的初始质量函数相关),ε为超新星能量转换为动能的效率。其中的ESNe∼1051erg为单个超新星的典型质量。当Eeje=E时,可以得到, MgasM∗=0.4ε(c10)−1(Vvir200km/s)−2 对于一个银河系尺度的暗晕,即使超新星能量全部可以转化为动能,产...
The positive feedback between oxygen levels in atmosphere and primary productivity caused progressive oxygenation in ocean–atmosphere system and enable phosphorites to be formed by different mechanisms. Results show that the Lower Doushantuo consist of abiotic intraclasts and exhibited “seawater-like” ...
Fast positive feedback between the adrenocortical stress response and a brain mechanism involved in aggressive behavior. Aggressive behavior induces an adrenocortical stress response, and sudden stressors often precipitate violent behavior. Experiments in rats revealed a fast... MR Kruk,J Halász,W Meeli...
Considering the proposed vapour-phase mechanism, a positive feedback in angiosperm leaf evolution may emerge from the combined adaptations of stomatal traits and leaf venation because additional carbon uptake can increase growth and productivity. These additional carbon gains may have been invested in exp...
This biological fluorescence indication was used as a positive feedback mechanism for algorithm training. Subsequently, we used the trained classifier to generate the isolated binary images, where the fluorescence signal areas were masked out as the overlay [Fig. 1b]. The observations showed that ...
