In this article we review the diagnosis and current management of epithelial ovarian cancer which accounts for over 95 percent of the ovarian malignancies. We will present various theories about the potential origin of ovarian malignancies. We will discuss the genetic anomalies and syndromes that may cause ovarian cancers with emphasis on Breast cancer type 1/2 mutations. The pathology and pathogenesis of ovarian carcinoma will also be presented. Lastly, we provide a comprehensive overview of treatment strategies and staging of ovarian cancer, conclusions and future directions.展开更多

Multicast is a form of communication that delivers information from a source to a group of destinations. In a single-channel WMN, all nodes share and communicate with each other via the same channel. In such a network, the throughput capacity of multicast degrades significantly as the network size increases. A critical factor that contributes to this rapid degradation is the co-channel interference in single-channel WMNs. The major advantage of WMN is that power is not the major issue as compare to other wireless network like MANET, Sensor etc. Hence Power can be optimally utilized in WMN to increase throughput and total network efficiency. In this paper, we propose a channel assignment algorithm for multicast based on high channel capacity with minimum interference. This scheme usesall overlapping and non overlapping channel for the channel assignment. By this scheme we provide better performance in terms of average packet delivery ratio, average throughput and average end to end delay with respect to multichannel multicast channel assignment schemes.展开更多
