ABSTRACT

Infectious and contagious diseases exist in humanity for many centuries which causes a curb in the growth of the population. Immunization plays a vital role to prevent mortality and morbidity against infectious diseases. COVID-19 pandemic continues to rage the urgency of developing a vaccine that should ensure the safety, efficacy, swift and fair deployment, implementation, and monitoring of vaccines across the globe. In the present context, the vaccine production to immunization campaign is a critical challenge. Therefore, an effective vaccine supply chain mechanism is required to address issues such as counterfeit vaccines, reduce vaccine wastages, and vaccine record fraud. In this paper, a blockchain-enabled vaccine supply chain is proposed to ensure the correctness, transparency, trust, and immutable log and improve the efficiency of vaccine distribution in the cold chain. The uniqueness of the proposed system is to provide distributed system to verify the reliability and efficacy of the vaccine from production to end beneficiaries' feedback about the vaccine. Our proposed system gives a clear view to the users as well as to the healthcare provider about the vaccination and ensures the anticounterfeit vaccine. The proposed system minimizes counterfeit vaccines and records, provides transparent communication between stakeholders in the supply chain, and improves the security of the vaccine supply chain and immutable feedback system about the vaccine.

ABSTRACT

Chrysin (a flavonoid) has shown various promising pharmacological activities viz. anticancer, anti-diabetic, immune-modulation, antidepressant, and anti-asthmatic. Additionally, it exhibited potential protective effects against various toxins on different organs like the liver, brain, kidney, and heart. A multitude of studies have been conducted to explore the possible targets for its possible mechanism of action. However, its therapeutic applications have been limited due to its poor oral bioavailability. The major reason for its poor bioavailability is its extensive first-pass metabolism. A critical review of the pharmacological properties of chrysin and its associated molecular targets has not been discussed as yet comprehensively. Therefore, the emphasis of the present work is to provide an in-depth understanding of molecular targets accountable for the pharmacological actions of chrysin. Moreover, a schematic diagram was made for the first time to represent the comprehensive pharmacokinetic properties of chrysin, which helps to understand the biopharmaceutical aspect for its successful delivery. An in-depth understanding of the biopharmaceutical properties of chrysin will help in adopting a suitable formulation approach to overcome poor oral bioavailability. Additionally, it facilitates to study the possible pharmacokinetic interactions of chrysin with other drugs. Hence, we found that chrysin is a miraculous natural agent with myriad therapeutic properties, and its benefit can be exploited with an in-depth understanding of molecular targets, pharmacological actions, and biopharmaceutical attributes.

ABSTRACT

Nowadays, internet technology plays a vital role in all the fields of our daily lives ranging from the world economy, professional careers, higher education, and almost all the spheres that are deeply impacted. In the current situation, due to COVID19, the dependence on the Internet for almost everything, including learning, getting daily needs, etc., is heavily dependent on the Internet. Online learning is made possible by the Internet, and today most students, educators, researchers are leveraging online learning platforms to enhance their knowledge at their own pace. Generally, the quality of the E-learning courses is evaluated with the help of the courses' review and rating mechanisms. In the present context, review systems are centralized, storing highly valuable information at one location and are liable to manipulation, hacking, and tampering. In this paper, the Blockchain-based Online Education Content Ranking system is proposed for an online review and ranking system that offers a decentralized trustworthy system, ensuring the integrity of the rating and the independence and integrity of content reviews by Subject Matter Experts (SME).

Online learning is made possible by the Internet, and today most students, educators, researchers are leveraging online learning platforms to enhance their knowledge at their own pace. Generally, the quality of the E-learning courses is evaluated with the help of the courses’ review and rating mechanisms. In the present context, review systems are centralized, storing highly valuable information at one location and are liable to manipulation, hacking, and tampering. In this paper, the Blockchain-based Online Education Content Ranking system is proposed for an online review and ranking system that offers a decentralized trustworthy system, ensuring the integrity of the rating and the independence and integrity of content reviews by Subject Matter Experts (SME).
