Paraquat toxicity occurs through the high production of reactive oxygen species (ROS) which cause damage due to oxidative stress. Antioxidants can reduce prevention Taurine has shown ability act as an antioxidant. The aim this research is find a effect antioxidant taurine decrease kidney caused by stress paraquat looking at histopathology changes. 25 male adult mices from strain DDY were used a...

UTILITY: (1) Assess degree of fibrosis. H&E stain is not reliable for demonstration of fibrosis especially in early stages. Pericellular fibrosis around the central vein in steatohepatitis can be difficult to identify on the H&E stain. (2) Distinguish fibrosis from necrosis. In acute hepatitis, areas of confluent necrosis can be difficult to distinguish from fibrosis and can lead to an erroneou...

BACKGROUND The prevalence of flap necrosis after palatoplasty in patients with cleft palate. The prevalence of mucoperiosteal flap necrosis after palatoplasty remains unknown, and this complication is rare. This event is highly undesirable for both the patient and the surgeon. We present here a new scale to evaluate the degree of hypoplasia of the palate and identify patients with cleft palate ...

ABSTRACT A pathosystem consisting of the model plant Medicago truncatula and the rust fungus Uromyces striatus was characterized. From a collection of 113 mostly European accessions of M. truncatula, the vast majority were found to be susceptible to U. striatus, whereas 5 accessions showed strong resistance reactions. Stomatal surface characteristics, even if partly occluded, did not interfere ...

BACKGROUND To determine whether MRI feature analysis can differentiate benign retroperitoneal extra-adrenal paragangliomas and schwannomas. METHODS The MRI features of 50 patients with confirmed benign retroperitoneal extra-adrenal paragangliomas and schwannomas were retrospectively reviewed by two radiologists blinded to the histopathologic diagnosis. These features were compared between two...

OBJECTIVES Evaluate the degree of vascular occlusion, vascular recanalization, and necrosis of the vascular wall caused by polyvinyl alcohol-covered polyvinyl acetate (PVAc) particles compared to trisacryl particles after renal embolization. METHODS Seventy-nine female albino New Zealand rabbits underwent arterial catheterization of the right kidney. Thirty-three animals were embolized with t...

We attempted to develop a novel method for the chemical modification of cytokines with synthetic polymers to increase in vivo therapeutic efficacy. A pH-reversible amino-protective reagent, dimethylmaleic anhydride (DMMAn), was used for polymer conjugation of tumor necrosis factor-alpha (TNF-alpha) with polyethylene glycol (PEG). The novel PEGylated TNF-alpha, PEG-TNF-alpha(+), which was pretre...

OBJECTIVE To develop an experimental model of global normothermic ischemia able to demonstrate the transient ischemia and reperfusion periods required for development of ischemia/reperfusion injury in the small intestines of Wistar rats by clamping the abdominal aorta. METHODS Twenty adult male Wistar rats weighing 250-350g were randomly divided into five groups with four rats each and submit...

If the renal arteries of normal dogs are ligated, azotemia associated with some degree of hypertension occurs, and death results within a few days. In the heart, gall-bladder, stomach, and intestinal tract, medial necrosis of arterioles may be found together with focal hemorrhages and necrosis of smooth or cardiac muscle. The vascular changes were described by Goldblatt' and have been observed ...
