objective: the current study aimed to determine the efficacy of radioiodine-131 (131i) ablation therapy with thyroid hormone replacement one day before 131i administration in patients with well-differentiated thyroid cancer (dtc). methods: this retrospective study included 29 patients who underwent 131i therapies twice for dtc during 6-12 months.  since all the patients obviously had residual l...

an in vivo experiment was conducted to determine the effect of dietary betaine supplementation (betafin®) as a replacement for methionine on broiler performance and carcass characteristics. in a completely randomized design (crd) with five treatments of betaine levels (at 0, 25, 50, 75, and 100% in replacement for methionine) and five replicates of 10 birds/replicate, two hundred fifty-day-...

Heterotopic gastric mucosa (HGM) can occur in the foremidand hindgut and, conceivably, at any of their derivatives. The origin of HGM is either heterotopic (congenital) or metaplastic (acquired). The reported incidence of HGM in the endoscopic literature ranges from 0.29-10% but an incidence of up to 70% has been reported in autopsy studies. Heterotopic gastric mucosa patches have been reported...
