Longer term exposure to secondhand smoke and health outcomes in COPD: impact of urine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol.

Nicotine Tob Res 11(8):945-53 (2009) PMID 19587064

Secondhand smoke (SHS) contains respiratory irritants and has the potential to adversely affect adults with chronic obstructive pulmonary disease (COPD), but few studies have evaluated the impact of SHS on COPD.

  1. iota Horologi, the first coronal activity cycle in a young solar-like star

    arXiv:1305.1132 [astro-ph.SR] 6 May 2013

    We confirm the presence of an activity cycle of ~1.6 yr in i Hor both in X-rays and Ca II H&K. It is likely subject to the modulation of a longer, not yet constrained second cycle. The 1.6 yr cycle is the shortest coronal one observed to date, and i Hor represents the most active star for which a co...
  2. Root caries: a periodontal perspective.

    J Periodontal Res (2013) PMID 23647556

    Although there is extensive literature on root caries, consensus is lacking regarding certain aspects, such as diagnostic criteria, prevalence within populations and indisputable risk factors. Advancing age could be an aggravating factor in susceptibility to root caries for the periodontal patient;...
  3. Cigarette smoke extract induces differential expression levels of beta-defensin peptides in human alveolar epithelial cells.

    Tob Induced Dis 11(1):10 (2013) PMID 23627872

    This differential expression suggests that hBD3, hBD5, and hBD9 may play a role in the changes to the lung tissue observed in smokers. Establishing differential beta-defensin expression following CSE treatment will add to our understanding of the molecular response of the lung alveolar epithelium to...
