CN2F: A Cloud-Native Cellular Network Framework
Upcoming 5G and Beyond 5G (B5G) cellular networks aim to improve the
efficiency and flexibility of mobile networks by incorporating various
technologies, such as Software Defined Networking (SDN), Network Function
Virtualization (NFV), and Network Slicing (NS). In this paper, we share our
findings, accompanied by a comprehensive online codebase, about the best
practice of using different open-source projects in order to realize a flexible
testbed for academia and industrial Research and Development (R&D) activities
on the future generation of cellular networks. In particular, a Cloud-Native
Cellular Network Framework (CN2F) is presented which uses OpenAirInterface's
codebase to generate cellular Virtual Network Functions (VNFs) and deploys
Kubernetes to disperse and manage them among some worker nodes. Moreover, CN2F
leverages ONOS and Mininet to emulate the effect of the IP transport networks
in the fronthaul and backhaul of real cellular networks. In this paper, we also
showcase two use cases of CN2F to demonstrate the importance of Edge Computing
(EC) and the capability of Radio Access Network (RAN) slicing
The effect of aminoguanidine on sperm motility and mitochondrial membrane potential in varicocelized rats
Objective(s): Increased levels of nitric oxide (NO) in the testicular veins of people suffering from varicocele have already been reported. However, the role of NO-synthase (NOS) isozymes and their inhibitors have not been extensively studied. We aimed to evaluate the inhibitory effects of aminoguanidine (AG), on sperm motility, vitality, and mitochondrial membrane potential (MMP) in varicocelized rats. Materials and Methods: Twenty fore male Wister rats were divided into control, sham, varicocele, and treatment groups. Varicocele and treatment groups underwent partial ligation of left renal vein. Rats in the sham group underwent the same procedures as the varicocele group with the exception of vein ligation. 10 weeks after varicocele induction, sperm parameters were evaluated in all groups. The treatment group received 50 mg/kg AG injection daily for 10 weeks after which they were sacrificed prior to assessment of the parameters. Sperm viability and MMP were assessed by flow cytometry using propidium iodide (PI) and rhodamine 123 (Rh123), respectively. Results: The results of this study show a decrease in sperm viability, motility and MMP in the varicocele group compared with the other groups. After AG injection, we observed that all the parameters were significantly enhanced in the treatment group compared with the other groups. Rh123 staining revealed a positive relation between MMP and sperm motility, whereas PI staining showed a positive relation between sperm motility and viability. Conclusion: The findings of our study show that AG improves sperm motility and MMP, and thus, might be useful in the management of varicocele-related infertility
