Antioxidant activities of prickly pear ( Opuntia ficus indica) fruits and its betalains: betanin and indicaxanthin.

2004

Phytochemicals and phytomedicines are now an expanding research fields. A great number of active agents occurring in plants and herbs have been discovered, which is fundamental to find a rationale for the health effects of these herbs, in many cases used for centuries as traditional remedies. The knowledge of the mechanisms and molecular basis of their action is the final objective to understand the mode of action of the discovered principles. Studies on the bioactivity of cactus pear are very recent and results obtained so far, while exciting, now generate new questions. In vivo studies on healthy humans showed a strong protection of the body antioxidant system, and a marked reduction of p…

Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes

2022

Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021. Results…

Economics and Econometricsand (iii) COVID-19 cases in neighboring countries can lead to an increase in a country's domestic caseload and hamper efforts in taming its own local outbreak. Conclusions: By providing an early broad overview of the quantitative empirical estimates of the determinants of vaccine rollouts and the effects of COVID-19 vaccines our paper can help policymakers make informed decisions about local and global distributions of vaccines as well as related policy tools such as containment measure.Coronavirus disease 2019 (COVID-19)business.industryHealth PolicyNational accountsOutbreakGeneral Medicine(ii) vaccine deployment significantly reduces new COVID-19 infections Intensive Care Unit (ICU) admissions and fatalities and is more effective when coupled with stringent containment measures or when a country is experiencing a large outbreakVaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic.

Microplastics in the global aquatic environment: Analysis, effects, remediation and policy solutions

2019

This opinion paper reports on Microplastics (MPs) pollution in the aquatic environment. MPs are a global problem being detected everywhere: marine environment, wastewaters, surface waters, soils, sediments, food and air. MPs can also absorb organic contaminants, and can be ingested by organisms and introduced into the food web. MPs can be a vector as well of pathogens whereas airborne fibrous MPs may enter our respiratory system with risk to the environment and humans. Main issues and gaps related to MPs on-going and future research are highlighted: chemical analysis, fate in wastewater and drinking water treatment plants, environmental and human health effects as well as remediation strate…
