Esophageal cancer represents a major clinical challenge because of its poor prognosis. The aim of the SUDCAN collaborative study was to compare the net survival from esophageal cancer between six European Latin countries (Belgium, France, Italy, Portugal, Spain, and Switzerland) and report the trends in net survival and the dynamics of excess mortality rates (EMRs) up to 5 years after diagnosis...
Rectal cancer is a common and serious disease. The aim of the SUDCAN collaborative study was to compare the net survival from rectal cancer between six European Latin countries (Belgium, France, Italy, Portugal, Spain, and Switzerland) and provide trends in net survival and dynamics of excess mortality rates up to 5 years after diagnosis. The data were extracted from the EUROCARE-5 database. Fi...
In Europe as a whole, survival from skin malignant melanoma (SMM) has increased constantly since the 1980s. The aim of the SUDCAN collaborative study was to compare the trends in the 5-year net survival from SMM and in related excess mortality rate between six European Latin countries (Belgium, France, Italy, Portugal, Spain, and Switzerland). The data were extracted from the EUROCARE-5 databas...
A decline in total PCB levels in tissues of otters (Lutra lutra) from England and Wales, averaging 8% per year over the period 1983-1992, is reported. Mean PCB levels are now unlikely to pose a threat to otter populations.
Urmia Lake, located in north-west of Iran, has been exposed to various threats such as drought, construction of dams, land use changes and increased global temperature. Due to the importance of Urmia Lake, it is feasible to conduct different kinds of studies to identify the problems of its watershed. The main objective of this study was to evaluate SWAT program’s ability to simulate runoff in U...
PURPOSE Studies undertaken in England and Scotland have identified a decrease in the number of circumcision operations being performed during childhood. The aims of this study were two-fold. Firstly, to determine the trend in circumcision operations performed in boys in Northern Ireland over a ten year period. Secondly, to compare the number of operations performed by paediatric surgeons with t...
For decades, we monitored numbers and weights of the macrozoobenthos in a vast tidal-flat area Dutch Wadden Sea. We used data collected since 1992 to estimate annual secondary production. Data on chlorophyll concentrations primary production were available for nearby tidal inlet, showing rapid increases late 1970s gradual declines 1980s. The benthos responded with doubling biomass around 1980 s...
Background: An increase in the number of medical schools in Iran has caused a conspicuous escalation in medical research during recent years with the numbers of papers published in Iranian and international biomedical journals increasing annually. In addition to quantitative indices, the evaluation of medical research in Iran requires qualitative parameters. The aim of this study is the qualita...
