Influence of Farming System and Forecrops of Spring Wheat on Protein Content in the Grain and the Physicochemical Properties of Unsonicated and Sonicated Gluten.

The potential for enhancing the spring wheat protein content by different cultivation strategies was explored. The influence of ultrasound on the surface and rheological properties of wheat-gluten was also studied. Spring wheat was cultivated over the period of 2018-2020 using two farming systems (conventional and organic) and five forecrops (sugar beet, spring barley, red clover, winter wheat, or oat).

Effects of activation of endocannabinoid system on myocardial metabolism.

Endocannabinoids exert their effect on the regulation of energy homeostasis via activation of specific receptors. They control food intake, secretion of insulin, lipids and glucose metabolism, lipid storage. Long chain fatty acids are the main myocardial energy substrate.

Protective role of cannabinoid CB1 receptors and vascular effects of chronic administration of FAAH inhibitor URB597 in DOCA-salt hypertensive rats.

Aims: This study examined whether the fall in blood pressure (BP) induced by the chronic inhibition of fatty acid amide hydrolase (FAAH) by URB597 in deoxycorticosterone acetate (DOCA-salt) hypertensive rats correlates with endocannabinoid-mediated vascular changes.

Main Methods: Functional studies were performed in isolated endothelium-intact aortas and small mesenteric arteries (sMAs) using organ bath technique and wire myography, respectively.

Key Findings: In the DOCA-salt rats, methanandamide-stimulated relaxation was enhanced in sMAs or diminished in aortas.

Effect of tachycardia on lipid metabolism and expression of fatty acid transporters in heart ventricles of the rat.

Tachycardia increases oxidation of the plasma-borne long chain fatty acids in the heart. The aim of the present study was to examine effect of tachycardia on: 1) the total level of free fatty acids, diacylglycerols, triacylglycerols and phospholipids in both heart ventricles; 2) (14)C-palmitate incorporation in the lipid fractions; 3) expression of fatty acid and glucose transporters in the ventricles. Tachycardia was induced in anesthetized rats by electrical atrial pacing at the rate of 600/min.

Myocardial lipid profiling during time course of high fat diet and its relationship to the expression of fatty acid transporters.

Background/aims: It is well documented that increased fatty acids (FA) supply causes lipid accumulation and insulin resistance in skeletal muscles. Whether the same mechanism is present in the heart is still unclear. Therefore, the goal of our study was to determine the content of specific myocardial lipid fractions during feeding rats a high fat diet (HFD) for 5 weeks.
