Assessment of tobacco heating product THP1.0. Part 4: Characterisation of indoor air quality and odour

Publication date: March 2018 Source:Regulatory Toxicology and Pharmacology, Volume 93 Author(s): Mark Forster, John McAughey, Krishna Prasad, Eleni Mavropoulou, Christopher Proctor The tobacco heating product THP1.0, which heats but does not burn tobacco, was tested as part of a modified-risk tobacco product assessment framework for its impacts on indoor air quality and residual tobacco smoke odour. THP1.0 heats the tobacco to less than 240 °C ± 5 °C during puffs. An environmentally controlled room was used to simulate ventilation conditions corresponding to residential, office and hospitality environments. An analysis of known tobacco smoke constituents, included CO, CO2, NO, NO2, nicotine, glycerol, 3-ethenyl pyridine, sixteen polycyclic aromatic hydrocarbons, eight volatile organic compounds, four carbonyls, four tobacco-specific nitrosamines and total aerosol particulate matter. Significant emissions reductions in comparison to conventional cigarettes were measured for THP1.0. Levels of nicotine, acetaldehyde, formaldehyde and particulate matter emitted from THP1.0 exceeded ambient air measurements, but were more than 90% reduced relative to cigarette smoke emissions within the laboratory conditions defined Residual tobacco smoke odour was assessed by trained sensory panels after exposure of cloth, hair and skin to both mainstream and environmental emissions from the test products. Residual tobacco smoke odour was significantly lower from THP1.0 ...

Excessive amounts of alcohol intake can damage many organs or deaths in severe cases. Heavy alcohol intake is also known to cause gut leakiness, contributing to increased endotoxemia and inflammatory tissue damage in the liver and brain [1 –4]. Various pathological conditions, such as HIV infection [5–7], obesity [8], and burn injury [9], are known to increase gut leakiness and endotoxemia. In addition, binge alcohol [10] and nonalcoholic substances such as high fat diets [11] and fructose [12] can stimulate gut leakiness, leading to elevated serum endotoxin and liver inflammation.

ABSTRACTIntroductionSevere burns result in prolonged hypermetabolism and skeletal muscle catabolism. Rehabilitative exercise training (RET) programs improved muscle mass and strength in severely burned children. The combination of RET with β-blockade or testosterone analogs showed improved exercise-induced benefits on body composition and muscle function. However, the effect of RET combined with multiple drug therapy on muscle mass, strength, cardiorespiratory fitness, and protein turnover are unknown. In this placebo-controlled randomized trial, we hypothesize that RET combined with oxandrolone and propranolol (Oxpro...
