BACKGROUND Crassostrea gigas accumulates paralytic shellfish toxins (PST) associated with red tide species as Gymnodinium catenatum. Previous studies demonstrated bivalves show variable feeding responses to toxic algae at physiological level; recently, only one study has reported biochemical changes in the transcript level of the genes involved in C. gigas stress response. PRINCIPAL FINDINGS ...
Background and purpose: Therapeutic effects of Stachys lavandulifolia include anxiolytic effects also, it has beneficial effects in rheumatic diseases, genital tumors and cancerous ulcers but it showed adverse effects on liver and kidney. We investigated the subacute and subchronic toxic effect of Stachys lavandulifolia water extract in rat. Materials and methods: The animals were randomly div...
OBJECTIVES The aim of this study was to determine the incidence of toxic trough serum gentamicin levels in neonates in the first week of life, with different dosage intervals. METHODS This was a retrospective study of neonates born between 01.07.95 and 31.12.95, who received gentamicin. Data were collected on birth weight, gestation, gentamicin dose, the trough level of gentamicin, serum crea...
sirri island is one of the most important islands in iran where contains massive amounts of crude oil reservoirs and is a crude oil exporting and storage spot. petroleum sludge wastes produced by the refineries are deposited in outdoor 2-ha open pits. 30 sludge samples from different depot locations were conducted in 3-time intervals and mixed with each other to form one homogenized sample. the...

according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
This study was designed in such a way to assess the toxicity effect of 2,4D (Dichlorophenoxyacetic acid) pesticide in fish physiology and its antioxidant stress. Channa striatus fish were administered with two different doses compensation of 2,4-D pesticide of 100 and 200 mg/kg. After a matter of time interval the effect of 2,4-D on fish behavior and its toxic level was determined by assessing ...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
