Long-term Effects of Sulphur Dioxide Exposure in Pulp Mills

the effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...

Sulphur Dioxide Exposure

Bronchoalveolar lavage (BAL) which has not previously been used in investigating the effect of sulphur dioxide (SO2) on the human lung was performed on 12 subjects before and after controlled chamber exposure with SO2 for 20 minutes. BAL fluid 24 hours after exposure with 10 mg S02/m3 (4 ppm, 10 subjects) showed increased alveolar macrophage activity as judged by an increase in lysozyme positiv...

Long-term effects of Sulfur Mustard gas exposure on the skin of Iranian combaters

Background: During imposed war (1980-1988) Iraq frequently used chemical warfare particularly mustard gas. Skin is frequently involved in victims. Objective: Our main objective was to evaluate chronic skin manifestations due to exposure to mustard gas 10-19 years after exposure in a case-control study. Patients and Methods: 101 chemically wounded combators and 121 non-chemically wounded c...

Pulmotoxicological effects caused by long-term titanium dioxide nanoparticles exposure in mice.

Exposure to titanium dioxide nanoparticles (TiO(2) NPs) has been demonstrated to result in pulmonary inflammation in animals; however, very little is known about the molecular mechanisms of pulmonary injury due to TiO(2) NPs exposure. The aim of this study was to evaluate the oxidative stress and molecular mechanism associated with pulmonary inflammation in chronic lung toxicity caused by the i...
