Nowadays, the socioeconomic status has been changed a lot, so people are now more concerned about their life style and health. They have knowledge about the detrimental effects of synthetic products. That is why they are interested in natural products. Utilization of natural products of plant origin having fewer side effects has gained popularity over the years. There is immense scope for natural products that can intimate health benefits beyond traditional nutrients. Moringa oleifera is one such tree having tremendous nutritional and medicinal benefits. It is rich in macro- and micronutrients and other bioactive compounds which are important for normal functioning of the body and prevention of certain diseases. Leaves, flowers, seeds, and almost all parts of this tree are edible and have immense therapeutic properties including antidiabetic, anticancer, antiulcer, antimicrobial, and antioxidant. Most of the recent studies suggested that Moringa should be used as a functional ingredient in food. The aim of this review is to focus the use of Moringa oleifera as a potential ingredient in food products.

The urging need for seamless connectivity in mobile environment has contributed to the rapid expansion of Mobile IP. Mobile IP uses wireless transmission medium, thereby making it subject to many security threats during various phases of route optimization. Modeling Mobile IP attacks reasonably and efficiently is the basis for defending against those attacks, which requires quantitative analysis and modeling approaches for expressing threat propagation in Mobile IP. In this Paper, we present four well-known Mobile IP attacks, such as Denialof-Service (DoS) attack, bombing attack, redirection attack and replay attack and model them with Stochastic Game Petri Net (SGPN). Furthermore, we propose mixed strategy based defense strategies for the aforementioned attacks and model them with SGPN. Finally, we calculate the Nash Equilibrium of the attacker-defender game and thereby obtain the steady state probability of the vulnerable attack states. We show that, under the optimal strategy, an IDS needs to remain active 72.4%, 70%, 68.4% and 66.6% of the time to restrict the attacker's success rate to 8.5%, 6.4%, 7.2% and 8.3% respectively for the aforementioned attacks, thus performing better than the stateof-the-art approach.

: Coronaviruses (CoVs) belonging to the Betacoronavirus group, an unusually large RNA genome, are characterized by club-like spikes that project from their surface. An outbreak of a novel coronavirus 2019 (nCOVID-19) showing a unique replication strategy and infection has posed a significant threat to international health and the economy around the globe. Scientists around the world are investigating few previously used clinical drugs for the treatment of COVID-19. This review provides synthesis and mode of action of recently investigated drugs like Chloroquine, Hydroxychloroquine, Ivermectin, Selamectin, Remdesivir, Baricitinib, Darunavir, Favipiravir, Lopinavir/ritonavir and Mefloquine hydrochloride that constitute an option for COVID-19 treatment.
