Histamine causes vasodilation in the dog by activation of H1 and H2 receptors blocked by mepyramine and metiamide, respectively. Experiments were conducted in anesthetized dogs to determine the participation of H1 and H2 receptors in several forms of physiological dilatation. Mepyramine attenuated both histamine-induced and active-reflex dilatation in the hindlimb. Metiamide caused a further re...

Abstract To train, evaluate, and validate the application of a deep learning framework in three-dimensional ultrasound (3D US) for automatic segmentation ventricular volume preterm infants with post haemorrhagic dilatation (PHVD). We trained 2D convolutional neural network (CNN) from 3D US PHVD. The method was validated Dice similarity coefficient (DSC) intra-class (ICC) compared to manual segm...

conclusions the present case appears to offer a safe and relatively simple method of balloon dilatation inside the lumen of the embolized fragment when the foreign body is too distal to retrieve with conventional snare systems. introduction increasing numbers of complex percutaneous coronary interventions have been accompanied by various intra-procedural complications. the fracture and emboliza...

background nephrotoxicity is characterized and scored by many parameters such as vacuolization, dilatation, hyaline cast, debris or degeneration in injured renal tissue. in this short report, we attempt to find, the most correlated parameters with kidney tissue pathology damage score (pds) in cisplatin-induced nephrotoxicity. method a total of 207 normal and toxic rats’ kidney tissue (induced b...

Objective: The cows that don’t have access to sufficient energy in their ration can get sickness. Milk production has a high priority in metabolism of dairy cows so lactating cows are more prone to get sick This can ruin all the benefits of higher milk yield because of the higher prevalence of the disorders. Methods: Data for this research had gathered from a herd with 1600 Holstein cattle in E...
