Photochemical Degradation of the New Nicotine Pesticide Acetamiprid in Water
The objective of this study was to understand the photolysis pattern of acetamiprid in the water column and elucidate its degradation products and mechanism. It was observed that acetamiprid exhibited different photolysis rates under different light source conditions in pure water, with ultraviolet > fluorescence > sunlight; furthermore, its photolysis half-life ranged from 17.3 to 28.6 h. In addition, alkaline conditions (pH 9.0) accelerated its photolysis rate, which increased with pH. Using gas chromatography-mass spectrometry, five direct photolysis products generated during the exposure of acetamiprid to pure wa...

IJERPH, Vol. 21, Pages 478: Use of and Beliefs toward Novel Tobacco and Nicotine Products among Portuguese University Students: A Pandemic Survey
nço
Over the last decade, novel tobacco and nicotine product experimentation and use have dramatically increased among the youth, even in countries with strong tobacco control and anti-smoking social norms. We performed an online questionnaire-based cross-sectional study in March-June 2021, targeting students from the University of Beira Interior, Portugal. The aim was to assess the experimentation and use of tobacco and nicotine products and students’ beliefs towards these products. Of the 452 participants, 67.0% were female; the mean age was 21.9 ± 3 years. Most students (60.4%) reported...

Menthol versus tobacco e-liquid flavor: Impact on acute subjective effects, puff patterns, and intentions for use among Black and White menthol smokers
CONCLUSIONS: Among menthol smokers in a lab-based setting, findings suggest that menthol vs tobacco e-liquid flavor has little impact on acute changes in puff patterns, subjective experience, behavioral intentions, or craving and withdrawal.PMID:38613857 | DOI:10.1016/j.addbeh.2024.108038 (Source: Addictive Behaviors)

Tobacco use and dependence among adults residing in an urbanized village, Delhi, India
CONCLUSIONS: One in every five adults is a tobacco user in Aliganj. Manufactured cigarettes, bidi, and water pipes were the most common products among smokers. Among smokeless tobacco users, the most common products were chewing tobacco gutka, and khaini. A larger proportion of smokeless tobacco users had high nicotine dependence than smoked tobacco users.PMID:38605801 | PMC:PMC11006084 | DOI:10.4103/jfmpc.jfmpc_264_23 (Source: Primary Care)

The E-liquid Flavoring Vanillin Alters Energy and Autophagic Pathways in Human Proximal Tubule (HK-2) Epithelial Cells
In this study, acute exposure to the popular flavoring vanillin (VAN) was performed on human proximal tubule (HK-2) kidney cells. Cells were exposed to 0-1000 μM VAN for 24 or 48 h and cellular stress responses were determined. Mitochondrial viability using MTT assay showed a significant decrease between the control and 1000 μM group by 48 h. Seahorse XFp analysis showed significantly increased basal respiration, ATP production, and proton leak after 24 h exposure. By 48 h exposure, these parameters remained significantly increased in addition to non-mitochondrial respiration and maximal respiration. Glycolytic activity ...

IJERPH, Vol. 21, Pages 472: Provision of E-Cigarettes for Smoking Cessation in Pregnancy: Perceptions and Experiences of Pregnant Women from Two UK Sites
Conclusions: Providing e-cigarettes within smoking cessation services was indicated to be a positive and effective strategy for pregnant women trying to quit tobacco. However, numerous barriers to quitting and staying quit remained, suggesting scope for further improvements to smoking cessation support for pregnant women.
