Edible films were made from proteins (corn-zein and wheat gluten) and celluloses (methyl cellulose and hydroxypropyl cellulose), and tested fog permeability of gases. Oxygen and carbon dioxide permeabilities of edible films were generally lower than those of plastic films. However, water vapor permeabilities of edible films were higher than those of plastic films. The concentration of plasticiz...

fatty acid modified cellulose nanofibers (mcnfs) and tbhq antioxidant were added to poly(lactic acid) (pla) film. the combined effects of the mcnfs and tbhq on the morphological, thermal, mechanical and barrier properties of pla film were analyzed. the morphology of fracture surfaces evaluated by field emission scanning electron microscopy (fe-sem). xrd results showed that the crystallinity of ...

Abstract Introduction: Occurrence of cardiac arrhythmias and myocardial infarction are two main deleterious events that are caused by ischemia-reperfusion (IR) injury in the heart. Cardiac preconditioning represents the most potent method of rescuing heart tissue from undergoing irreversible ischemic damage. The aim of the present study was to evaluate oxytocin (OT) cardioprotective effect...

We have shown that propranolol reduces oxygen binding by hemoglobin in intact red cells by increasing the selective permeability of the red cell membrane resulting in an exodus of potassium, chloride, and water. The latter effects result in a new distribution of hydrogen ion between cell and plasma, and thereby a reduction in red cell pH. The reduction in pH can fully explain the change in hemo...
