Introduction: Snus is a smokeless tobacco product traditionally used in Scandinavia and available in pouched or loose forms. The objective of this study was to determine nicotine absorption for current pouched and loose snus products in comparison wi

Cigarette smoking is associated with chronic obstructive pulmonary disease (COPD)--a term encompassing chronic lung inflammation, chronic bronchitis and emphysema. Goblet cell hyperplasia is a characteristic feature of the lung epithelium in COPD pat

Cigarette smoke is composed of approximately 5% particulate phase and 95% vapour phase by weight. However, routine in vitro toxicological testing of smoke normally only measures the activity of the particulate phase. This study describes a new system

BACKGROUND: The extent of epithelial injury in asthma is reflected by expression of the epidermal growth factor receptor (EGFR), which is increased in proportion to disease severity and is corticosteroid refractory. Although the EGFR is involved in e

Asthma is regarded as an inflammatory disorder of the conducting airways characterized by a mast cell, eosinophil and T lymphocyte inflammatory response that is responsive to anti-inflammatory therapy, such as corticosteroids. In more severe and chro

Abnormal apoptotic mechanisms are associated with disease pathogenesis. Because the asthmatic bronchial epithelium is characteristically damaged with loss of columnar epithelial cells, we postulated that this is due to unscheduled apoptosis. Using an

In sensitized individuals, exposure to allergens such as Dermatophagoides pteronyssinus (Der p) causes Th2 polarization and release of cytokines, including IL-4 and IL-13. Because Der p extracts also have direct effects on epithelial cells, we hypoth

The effect of the anthranoids, anthralin and hypericin, on epidermal growth factor receptor (EGF-R) activation and their degree of specificity was examined. Hypericin, but not anthralin, was found to inhibit binding of [ 125 I]-labelled epidermal gro

Two proline mimetics, the enantiomers of 2-azabicyclo[2,2,1]heptane-3-carboxylic acid, have been incorporated in place of Pro30 into synthetic peptides based on the B-loop β-sheet sequence of human transforming growth factor-α (TGF-α) (residues Cy

Two morphologically distinct cell lines, GP2d and GP5d, derived from the same adenocarcinoma of the colon, have been established and characterised. Both clones have the same genetic changes, consistent with the usual pattern of tumour progression in
