A Practical Framework for Novel Electronic Nicotine Delivery System Evaluation: Chemical and Toxicological Characterization of JUUL2 Aerosol and Comparison with Reference Cigarettes.

Electronic nicotine delivery systems (ENDSs) are designed as a non-combustible alternative to cigarettes, aiming to deliver nicotine without the harmful byproducts of tobacco combustion. As the category evolves and new ENDS products emerge, it is important to continually assess the levels of toxicologically relevant chemicals in the aerosols and characterize any related toxicology. Herein, we present a proposed framework for characterizing novel ENDS products (i.

Photoactive Herbal Compounds: A Green Approach to Photodynamic Therapy.

Photodynamic therapy (PDT) is a minimally invasive, alternative, and promising treatment for various diseases, including cancer, actinic keratosis, Bowen's disease, macular degeneration, and atherosclerotic plaques. PDT involves three different components, photosensitizers (PS), molecular oxygen, and light. The photoactivation of administered PSs using a specific wavelength of light in the presence of molecular oxygen leads to the generation of reactive oxygen species that leads to tumour cell death.

Relationship between wood fuel energy consumption and forest degradation at regional and sub-regional levels of sub-Saharan Africa: the role of control of corruption and government effectiveness.

This paper examines the effect of wood fuel energy consumption on forest degradation at regional and sub-regional levels of sub-Saharan Africa by taking into consideration the role of control of corruption and government effectiveness. To achieve the objective of the study, system generalized method of moments was used on a sample of 45 sub-Saharan African countries over the 2005-2013 period. The estimated results of the study revealed that wood fuel consumption impact positively on forest degradation at sub-Saharan Africa's level.

Can clean biomass energy use lower CO emissions in African economies? Empirical evidence from dynamic long-run panel framework.

This paper seeks to answer an empirical question of whether clean biomass energy consumption lowers CO emissions while controlling for technical innovation in eight selected countries from Africa for the 1980-2015 period. The countries which are chosen based on availability of data on biomass energy and technological innovation include Egypt, Algeria, South Africa, Mauritius, Kenya, Morocco, Tunisia, and Zambia. Applying pooled mean group, mean group, and dynamic fixed effect panel estimators, the results indicate that clean biomass energy use decreases CO emission in the long run.
