In this study, a 2-pack isocyanate curing waterborne paint (without organic solvents) encapsulating dibutyltin dilaurate (hereinafter, DBTL) in nonionic surfactant micelles with an hydrophilic–lipophilic balance of 13–14 advance releases DBTL when the are collapsed at 80 °C or higher, whereby progresses rapidly. On other hand, viscosity levels before and after being left 40 for 1 h almost same....
Yermakoff, Jeannee Karen. M.S., University of Rhode Island, 1978. An Experimental Model of Hepatic Fibrosis Induced by the Administration of Dibutyltin Dichloride. Major Professor: Dr. George C. Fuller. Dibutyltin dichloride (DBT}, one of a series of dialkyltin derivatives used industrially as polyvinylchloride stabilizers and urethane catalysts, was investigated for its I ability to induce liv...
Tributyltin, an organotin, is ubiquitous in the environment. The consumption of contaminated marine species leads to human dietary exposure to this compound. Tributyltin is an endocrine disruptor in many wildlife species and inhibits aromatase in mammalian placental and granulosa-like tumor cell lines. We investigated the effects of tributyltin chloride exposure on pregnancy outcome in the Spra...
در این تحقیق، از روش آسان و موثر رفلاکس جهت سنتز نانوذرات مس ایندیوم سولفید استفاده شد و نانو ساختار های متنوع روی اکسید با بکارگیری روش هیدروترمال سنتز شدند. سپس با کمک یک فرایند حرارتی نانوکامپوزیت zno/cis تهیه شد. محصولات به وسیله روش های پراش اشعه ایکس (xrd)، طیف سنجی زیر قرمز (ft-ir)، میکروسکوپ الکترونی روبشی (sem) و طیف سنجی uv- visمورد شناسایی قرار گرفتند. تصاویر sem، مورفولوژی نانوذره ب...
BACKGROUND Organotins are highly toxic and widely distributed environmental chemicals. Dibutyltin (DBT) is used as stabilizer in the production of polyvinyl chloride plastics, and it is also the major metabolite formed from tributyltin (TBT) in vivo. DBT is immunotoxic, however, the responsible targets remain to be defined. Due to the importance of glucocorticoids in immune-modulation, we inves...
The relationship between pancreatic fibrosis and apoptosis of pancreatic acinar cells has not been fully elucidated. We reported that taurine had an anti-fibrotic effect in a dibutyltin dichloride (DBTC)-chronic pancreatitis model. However, the effect of taurine on apoptosis of pancreatic acinar cells is still unclear. Therefore, we examined apoptosis in DBTC-chronic pancreatitis and in the AR4...
