Abstract A number of nitrones containing a partially hindered phenolic group are shown to be effective antidegradants for sulfur vulcanized rubbers. They exhibit a high level of antiozonant and antifatigue activity, but unlike commercial antiozonants they do not cause discoloration of light colored formulations. The new antidegradants are less effective than conventional additives as thermal antioxidants, but their performance as antifatigue agents and antioxidants is augmented by their use in combination with nonstaining antioxidants. The mechanism of action of the phenolic nitrones is believed to involve their oxidation to stable phenoxyl/nitroxyl radicals.

This study investigated the effects of flaxseed and vitamin E on diabetic nephropathy lesions in an experimental-induced model of diabetes in hamsters. Diabetes was induced by intraperitoneal injection of streptozotocin (STZ) in male Golden Syrian hamsters, and diabetic animals were fed either standard diet, or standard diet supplemented with flaxseed (150 g/kg diet), vitamin E (400 mg a-tocopherol/kg diet) or combination of flaxseed and vitamin E in the same dosages, for 20 weeks. Kidney histological evaluation of the diabetic hamsters revealed histological lesions characteristic for diabetic nephropathy, while supplementation of the diet with flaxseed and/or vitamin E improved histological aspects of diabetic nephropathy.
