Ethnomedicinally Rumex hastatus D. Don has been used since long for various ailments especially in neurological disorders. The reported data and the importance of Rumex genus demonstrate the vital medicinal value of R. hastatus. In the current investigational study, isolation of essential oil and its antioxidant and anticholinesterase assays were performed. The essential oil of R. hastatus was analyzed by GC-MS for the first time. The essential oil was evaluated for anticholinesterase and antioxidant assays. The anticholinesterase assay was conducted at various concentrations (62.5 to 1000 μg/ml) against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Similarly, the antioxidant potential was determined using DPPH and ABTS free radicals. The GC-MS analysis of essential oil showed 123 components. The result recorded for the anticholinesterase assays demonstrated a marked potential against AChE and BChE with IC50 values of 32.54 and 97.38 μg/ml respectively which were comparable with the positive control i.e., galanthamine (AChE, IC50 = 4.73 μg/ml and BChE, IC50 = 11.09 μg/ml). The antioxidant assays against DPPH and ABTS free radicals also exhibited significant scavenging potential with IC50 values of 3.71 and 6.29 μg/ml respectively, while for ascorbic acid the IC50 value was <0.1 μg/ml against both free radicals. Based on the current investigational studies, it may be concluded that R. hastatus is an effective source of essential oil's components having anticholinesterase and antioxidant potentials, which after subjecting to drug development may lead to novel drug candidates against neurodegenerative disorders.

The Fourth Industrial Revolution (Industry 4.0) represents a significant change in how we live and interact. A new era of human development has begun due to massive technological developments similar to the Industrial Revolution. These advances are integrating the physical and digital worlds in a way that also carries significant risks. Revolutions are driving us to rethink how nations evolve. Industry 4.0 offers opportunities for all citizens from all socioeconomic levels and countries. There is real hope in going outside of technology and creating a method to enable it. It takes a large number of people to have a positive influence on an individual, organization, and community. Achieving resource-efficient and user-friendly production solutions require intelligent and precise equipment. Industry 4.0 is expected to benefit from new technologies and applications by increasing production and providing customized products on demand. The term “Industry 4.0” first appeared a few years ago in response to the concept of Industry 4.0. This has become a concern for policymakers and organizations due to the impact of the pandemic, a focus on topics such as sustainability and resilience, and a renewed focus on human needs. Major industries around the world are looking for headlines about cutting-edge technologies that can help them streamline operations and reduce expenses. Executives at logistics companies do the same to better prepare their companies for the future. After all, the logistics business has traditionally relied on manual operations and data storage, and new technological solutions help it a lot. Cutting-edge technology refers to technical equipment and processes. We will discuss cutting-edge technology and how it fits into Industry 4.0. We present challenges and solutions to enabling cutting-edge technologies that support Industry 4.0. We focus on an open problem and many research questions that have been developed to enable cutting-edge technologies that support Industrial Revolution 4.0.

Hydrazones are active compounds having an azomethine –NHN=CH group and are widely studied owing to their ease of preparation and diverse pharmacological benefits. Novel isonicotinic hydrazone derivatives of vanillin aldehyde and salicyl aldehyde were synthesized that had azomethine linkages and were characterized by UV–Visible, FTIR, EI-MS, 1H-NMR and 13C-NMR spectroscopy. The compounds were screened for their antibacterial activity against Staphylococcus aureus, Bacillus subtilus, and Escherichia coli using disc diffusion and minimum inhibitory concentration (MIC) methods. For cytotoxicity, a brine shrimp lethality test was performed to calculate the lethal concentration (LC50). The results demonstrated appreciable antibacterial activities against the applied strains, amongst which the compounds coded NH3 and NH5 showed maximum inhibition and MIC responses. In terms of cytotoxic activity, the maximum effect was observed in compound NH5 and NH6 treatments with minimum survival percentages of 36.10 ± 3.45 and 32.44 ± 2.0, respectively. These hydrazones could be potential candidates in antitumorigenic therapy against various human cancer cells.

The use of computers is becoming more and more common. The power and maliciousness of powerful attackers are increasing. Organizations must improve their ability to mitigate information security threats. Adequate protection is more critical than ever. With websites and social media platforms holding a wealth of personal information and potentially damaging content, attackers use the internet's sophisticated hacking tools to cause harm to individuals and organizations. Attacks have become stealthier, with more significant economic damage and broader damage. Blockchain must be the solution to the security problem of financial transactions. However, judging from the results and expected answers from the industry and organization, it is crucial to understand how financial institutions deal with these issues by looking at blockchain deployments in cybersecurity. A blockchain is a digital database that records all mentoring transactions. This technology supports many different exchanges that are currently in use. The authors also believe that blockchain should be integrated into many parts of cybersecurity. The primary goal of this chapter is to review relevant research papers and book chapters over the past 10 years to understand how successful cybersecurity and blockchain implementations have been in the enterprise and to identify the different challenges and concerns that enterprise personnel face. They also provide suggestions and solutions to problems.
