Abstract Background and Aims Cellular senescence is an adaptative process in response to damage or stress. It consists of a cell-cycle-arrest (CCA) alternatively the programmed cell death process, which necessary for regeneration damaged tissues. However, permanent promotes aberrant inflammatory associated chronic diseases, fibrosis aging. One mechanisms triggers cellular DNA (DDR) activation, ...

In order to decrease energy consumption caused by the dense deployment of pico base stations (PBSs) in heterogeneous cellular networks (HetNets), this paper first analyzes efficiency (EE) two-tier HetNets and then proposes a method maximize network EE adjusting PBS transmit power. The are modeled Poisson point process (PPP) hole (PHP), coverage probability macro station (MBS) is derived based o...

Abstract Wound healing involves four stages: haemostasis, inflammation, proliferation, and remodelling. Each wound should be considered separately because of the tissue’s different environment. The key to successful is cell signalling synchronisation between cells chemical transmitters, which gradient attracts immune prevents pathogens from causing infection. Both skin oral mucosa stages proces...
