A Cellular Response to an Internal Energy Crisis
نویسندگان
چکیده
Lack of an appropriate energy supply has been thought to induce cell death in a nonspecific manner by causing a decline in metabolism and a gradual cessation of cellular function. In this issue of Cell, Nutt et al. (2005) describe a new mechanism that directly links nutrient availability to apoptosis in Xenopus oocytes and show that age-dependent changes in the nutritional state of a cell might lead to caspase activation and apoptotic cell death.

متن کاملCoordinated resource scheduling in a large scale virtual power plant considering demand response and energy storages
Virtual power plant (VPP) is an effective approach to aggregate distributed generation resources under a central control. This paper introduces a mixed-integer linear programming model for optimal scheduling of the internal resources of a large scale VPP in order to maximize its profit. The proposed model studies the effect of a demand response (DR) program on the scheduling of the VPP. The pro...
