The cryptocurrency market has been developing dynamically in recent years. The rapid development of the market is the result of increased interest in cryptocurrencies both from the entities treating it as a means of payment and from investors acquiring cryptocurrency for speculative purposes. Blockchain technology, on the basis of which cryptocurrencies are created, has gained acceptance in the financial industry and many entities are conducting advanced work on its use in their operations. On the other hand, numerous supervisors, including the European Banking Authority, the European Central Bank, the National Bank of Poland, and the Polish Financial Supervision Authority warn against investing in cryptocurrencies, indicating the numerous risks associated with such investments. The aim of the article is to analyze the potential risks and benefits of investing in cryptocurrencies. The main risks related to investments in cryptocurrency were analyzed on the example of bitcoin, and the rate of return and correlations with changes in the currency prices of other financial instruments were analyzed.

The institutional review board (IRB) Is charged with assessing the risks and benefits of research projects Involving human subjects. Ethical considerations and federal regulations require that an IRB, in part, must find that the potential risks of participation are proportional to the potential benefits (If any) and to the Importance of the knowledge that may be learned before the IRB can approve the voluntary assumption of risk by a research participant. Adequate assessment of the risks and benefits requires careful scrutiny of the study design In relation to the study objectives.

The Emergency Use Authorization (EUA) mechanism is central to the US response to coronavirus disease 2019 (COVID-19). It allows the US Food and Drug Administration (FDA) to respond quickly to novel threats by approving a new drug, device, or diagnostic procedure or expanding off-label use of an existing drug through an accelerated approval process.1 To obtain authorization, evidence must support that a drug or product “‘may be effective’ to prevent, diagnose, or treat serious or life-threatening diseases or conditions,” and the known or potential benefits of the product must outweigh known or potential risks.2(p7) The authorization also stipulates that when feasible, a fact sheet is provided to address risks and benefits and make clear that acceptance is voluntary.2 (Am J Public Health.

AbstractSedation is an essential therapeutic strategy in the care of neurocritical patients. Intravenous sedative agents are the most widely used, with promising alternatives (dexmedetomidine, ketamine, and volatile agents) to propofol and midazolam arising. Studies designed to evaluate superiority and avoid biases are required. A neurological awakening test is safe in most patients. Potential risks and benefits of limiting deep sedation and daily interruption of sedation in these patients remain unclear. The aim of this review was to report recent clinical evidence on sedation in this subgroup of patients, focusing on its effects on clinical prognosis.

Blockchain technology has emerged as a promising technology with far-reaching implications for the food industry. The combination of immutability, enhanced visibility, transparency and data integrity provides numerous benefits that improve trust in extended food supply chains (FSCs). Blockchain can enhance traceability, enable more efficient recall and aids in risk reduction of counterfeits and other forms of illicit trade. Moreover, blockchain can enhance the integrity of credence claims such as sustainably sourced, organic or faith-based claims such as kosher or halal by integrating the authoritative source of the claim (e.g., the certification body or certification owner) into the blockchain to verify the claim integrity and reassure business customers and end consumers. Despite the promises and market hype, a comprehensive overview of the potential benefits and challenges of blockchain in FSCs is still missing. To bridge this knowledge gap, we present the findings from a systematic review and bibliometric analysis of sixty-one (61) journal articles and synthesize existing research. The main benefits of blockchain technology in FCSs are improved food traceability, enhanced collaboration, operational efficiencies and streamlined food trading processes. Potential challenges include technical, organizational and regulatory issues. We discuss the theoretical and practical implications of our research and present several ideas for future research.

AbstractWith the rapid development of science and technology, increasing research interests have been focused on environment protection, global warming, and energy shortage. At present, reducing friction force as much as possible has developed into an urgent issue. Sharkskin effect has the potential ability to lower viscous drag on the fluid-solid interface in turbulence, and therefore, how to fabricate bio-inspired sharkskin surfaces is progressively becoming the hot topic. In this review, various methods of fabricating drag reduction surfaces covering biological sharkskin morphology are illustrated and discussed systematically, mainly involving direct bio-replicated, synthetic fabricating, bio/micro-rolling, enlarged solvent-swelling, drag reduction additive low-releasing, trans-scale enlarged three-dimensional fabricating, flexible printing, large-proportional shrunken bio-replicating, ultraviolet (UV) curable painting, and stretching deformed methods. The overview has the potential benefits in better acquainting with the recent research status of fabricating sharkskin surfaces covering the biological morphology.
