In recent years, there has been a growing concern about potential impacts on public health and wellbeing due to exposure to environmental odour. Separation distances between odour-emitting sources and residential areas can be calculated using dispersion models, as a means of protecting the neighbourhood from odour annoyance. This study investigates the suitability of using one single year of meteorological input data to calculate reliable direction-dependent separation distances. Accordingly, we assessed and quantified the inter-annual variability of separation distances at two sites with different meteorological conditions, one in Brazil and the other in Austria. A 5-year dataset of hourly meteorological observations was used for each site. Two odour impact criteria set in current regulations were selected to explore their effect on the separation distances. The coefficient of variation was used as a statistical measure to characterise the amount of annual variation. Overall,for all scenarios, the separation distances had a low degree of inter-annual variability(mean coefficient of variation values from 8% to 21%). Reasonable agreements from year to year were therefore observed at the two sites under investigation, showing that one year of meteorological data is a good compromise to achieve reliable accuracy. This finding can provide a more cost-effective solution to calculate separation distances in the vicinity of odour sources.

Absence of Expression of OCT-2 in Gastric Cancer Cells

American Journal of Molecular Biology 2014年第3期4卷 129-133页

OCT-2, a member of the POU homeodomain family of transcription factors, has been implicated in gastric cancer lymph node metastasis on a single publication so far. Other members of the same family of transcription factors were found to have a role in intestinal metaplasia and gastric cancer (OCT-1) and in trophectoderm differentiation of embryonic stem cells (OCT3/4) via modulation ofCDX2. These findings prompted us to evaluate whether OCT-2 could in fact have a role in gastric oncogenesis and lymph node metastasis in human gastric cancer, designing an immunohistochemistry study of the putative expression of OCT-2 on human gastric cancer tissue of 69 surgical archival specimens of intestinal and diffuse type. We could not find expression of OCT-2 on any of our cancer tissues, metaplasia or normal gastric mucosa despite the expression of OCT-2 on tonsil lymphatic cells (tissue test) and normal lymph nodes. We concluded that, based on immunohistochemistry, OCT-2 does not have a role in gastric oncogenesis nor does have any relationship with lymph node metastasis in gastric cancer.
