Although several neural pathways have been implicated in feeding behaviors in mammals [1–7], it remains unclear how the brain coordinates feeding motivations to maintain a constant body weight (BW). Here, we identified a neuropeptide pathway important for the satiety and BW control in Drosophila. Silencing of myoinhibitory peptide (MIP) neurons significantly increased BW through augmented food intake...
Background Appropriate vertical movement is critical for the survival of flying animals. Although negative geotaxis (moving away from Earth) driven by gravity has been extensively studied, much less is understood concerning a static regulatory mechanism for inducing positive geotaxis (moving toward Earth). Results Using Drosophila melanogaster as a model organism, we showed that geomagnetic field...
Animals can detect and consume nutritive sugars without the influence of taste. However, the identity of the taste-independent nutrient sensor and the mechanism by which animals respond to the nutritional value of sugar are unclear. Here, we report that six neurosecretory cells in the Drosophila brain that produce Diuretic hormone 44 (Dh44), a homolog of the mammalian corticotropin-releasing hormone...
For the last few years, there has been a large volume of research on Peer-to-Peer (P2P) system, resulting in many hybrid P2P models. This model is important to keep a high available SP because all P2P overlay traffic will be routed via the SP. Main purpose of this paper is to improve SP's availability for OPs so that the system selects the peer with the potential to go the longest without needing...
For the last few years, there has been a large volume of research on peer-to-peer (P2P) systems, resulting in many hybrid P2P models. In the hybrid model, all P2P overlay traffic will be routed via the SP. In this model, the SP selection and replacement are important to accomplishing high scalability and reliable service in P2P network. Main purpose of this paper is to provide highly available SP...
