Cigarette smoke, a mixture of over 7,000 chemicals, can affect development of the nervous system prenatally, which can produce cognitive problems in children after birth. The purposes of this study were to determine if chemicals in mainstream (MS) and side-stream (SS) cigarette smoke adversely affect proliferation of neural stem cells, which could explain the effects observed in humans, and to ...

ABSTRACT The growth of good and quality seeds requires a lot fertilization, considering that oil palm grow quickly. Generally, the fertilizers used are compound inorganic single fertilizers. Continuous use without being balanced by organic can reduce soil quality. Therefore, alternative needed to Liquid smoke from midrib-leaf waste be developed into fertilizer, so studies needed. This study aim...

This study aims to identify support for smoke-free policies among university students. A cross-sectional was conducted 406 students from three main campuses of a in 2018. standardized questionnaire administered on sociodemographic characteristics, knowledge, and habits towards tobacco use influence. There significant association between knowledge secondhand smoke (SHS) the types tobacco-free po...

During wildfires large amounts of volatile phenols (VP’s) are released into the air from wood burning. These compounds absorb through berry skin, where they quickly glycosylated. Studies have shown that both free and bound contribute to smoke taint perception. For grape exposure risk assessment, natural amount VP’s in grapes (baseline) as well rejection threshold levels these different wine mat...

INTRODUCTION In 2011, the Mobile County Health Department began a 12-month antismoking educational media campaign to educate citizens on the dangers of secondhand smoke. The campaign overlapped with the Centers for Disease Control and Prevention's 3-month national antismoking Tips from Former Smokers media campaign. We aimed to evaluate the effect of these campaigns on support for smoke-free en...

Glutaredoxins (Grx) are redox enzymes that remove glutathione bound to protein thiols, know as S-glutathionylation (PSSG). PSSG is a reservoir of GSH and can affect the function of proteins. It inhibits the NF-κB pathway and LPS aspiration in Grx1 KO mice with decreased inflammatory cytokine levels. In this study we investigated whether absence of Grx1 similarly repressed cigarette smoke-induce...

The purpose of this study was to test the hypothesis that components in mainstream (MS) and sidestream (SS) cigarette smoke inhibit growth and angiogenesis using the chick chorioallantoic membrane (CAM). Varying doses of whole or gas-phase MS and SS smoke solutions were placed on day 5 CAMs, and their effects on angiogenesis were evaluated on day 6. All parameters evaluated (CAM area, major blo...

In room–corridor building geometry, the corridor smoke temperature is of great importance to fire protection engineering as indoor fires occur. Theoretical analysis and a set of reduced-scale model experiments were performed, and a virtual fire model was proposed, to investigate the correlations between the maximum smoke temperature in corridors and the smoke temperature in rooms. The results s...

Cigarette smoke is well known for its adverse effects on human health, especially on the lungs. Basic research is essential to identify the mechanisms involved in the development of cigarette smoke-related diseases, but translation of new findings from pre-clinical models to the clinic remains difficult. In the present study, we aimed at comparing the gene expression signature between the lungs...

The pathogenesis of cigarette smoke-induced pulmonary hypertension is not understood. We have previously shown that smoke rapidly and persistently, but discoordinately, upregulates gene expression of mediators that control vasoconstriction, vasoproliferation, and vasorelaxation in small intrapulmonary arteries. To investigate the possibility that smoke also induces endothelial dysfunction, a fi...
