Temperature and Salting out Effects on Nicotine Dissolution Kinetics in Saline Solutions [PDF]

open access: yesACS Omega, 2020
The dissolution rate of nicotine in aqueous solutions of sodium chloride (NaCl) was investigated at room temperature and 70 °C by quantitatively visualizing the shrinkage rate of microscopic nicotine droplets. Four different salt concentrations were used: 15 wt % (3.0 M), 20 wt % (4.3 M), 25 wt % (5.7 M), and the saturation NaCl concentration of 26 wt %

Cytotoxic and Oxidative Effects of Common Pesticides on Hepatic and Renal Cell Lines (HepG2 and Hek‐293): Implications for Human Health and Environmental Safety

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Modern agricultural practices expose humans and the environment to numerous chemical pesticides. Increasing evidence suggests that commercial pesticide formulations may exhibit toxicological properties that differ from those of their active ingredients alone due to the presence of co‐formulants and additives. This study evaluated the cytotoxic

Tobacco-derived and tobacco-free nicotine cause differential inflammatory cell influx and MMP-9 in mouse lung

open access: yesRespiratory Research
Background Electronic nicotine delivery systems (ENDS) or electronic cigarettes (e-cigarettes) aerosolize an e-liquid composed of propylene glycol (PG) and vegetable glycerin (VG) as humectants, flavoring chemicals, and nicotine.

Nicotine Salts and Synthetic Nicotine: New Challenges for an Old Problem

open access: yes, 2022
Smoking is recognized as a chronic disease caused by dependence on nicotine present in tobacco products. and is linked to a number of tobacco related diseases. In addition to this, it is considered a pediatric disease. In Brazil, treatment for smoking cessation since 2004 is offered at all levels of complexity by the National Health System (SUS ...

GSK3 Inhibition During Annelid Head Regeneration Results in a Hyper‐Proliferative Blastema and Impaired Differentiation

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
A whole‐body regenerative annelid was treated with a GSK3 inhibitor. While posterior regeneration was mostly normal, GSK3 inhibition prevented differentiation of anterior‐specific structures and instead produced a persistent, oversized, hyper‐proliferative blastema. This suggests that GSK3 promotes anterior identity and halts proliferation during axial

Crystal structures and hydrogen bonding in the proton-transfer salts of nicotine with 3,5-dinitrosalicylic acid and 5-sulfosalicylic acid

open access: yesActa Crystallographica Section E, 2014
The structures of the 1:1 anhydrous salts of nicotine (NIC) with 3,5-dinitrosalicylic acid (DNSA) and 5-sulfosalicylic acid (5-SSA), namely (1R,2S)-1-methyl-2-(pyridin-3-yl)-1H-pyrrolidin-1-ium 2-carboxy-4,6-dinitrophenolate, C10H15N2+·C7H3N2O7−, (I ...

Improving alkynyl(aryl)iodonium salts: 2-anisyl as a superior aryl group [PDF]

open access: yes, 2014
The majority of alkynyl(aryl)iodonium salts reported in the literature are derived from iodobenzene. This article describes the effects of varying this iodoarene building block on the synthesis, reactivity and stability of these salts.

Beyond a dual role: how Purpureocillium lilacinum reprograms citrus metabolism for integrated biocontrol and growth promotion

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Plants harbor complex microbial communities that are fundamental to their health and productivity. Among them, endophytic fungi such as Purpureocillium lilacinum establish mutualistic associations, offering dual benefits as plant growth promoters and biocontrol agents.
