Modification of the Fatty Acid Composition of Phospholipids in Liver, Myocardium and Plasma Tissues Under the Influence of Ionizing Radiation and With the Prior Application of a Hydrogen Sulfide Donor

Clinical significance of measuring fatty acids in biological fluids of dairy cows (in blood and milk) with a focus on heat stress

“…Keywords: dairy cows, heat stress, fatty acids, dietary strategies 2018). Polyunsaturated FAs (PUFAs), which are part of the phospholipids of biomembranes, provide their structure and regulate intracellular metabolism (Kovalchuk et al 2018).…”

“…Compensatory responses of animal bodies to the impact of heat include physiological (Sá-Filho et al 2018;Pinto et al 2020), behavioural (Heinicke et al 2018), including nutritional (Müschner-Siemens et al 2020; Chang-Fung-Martel et al 2021), clinical and metabolic reactions (Lees et al 2019;Mylostyva et al 2022), which affect their productivity (Herbut et al 2019;Silva and Costa 2018;Mylostyvyi et al 2021a). Reduced feed intake combined with increased consumption to maintain homeostasis during heat stress (HS) leads to a negative energy balance (NEB) in dairy cows (Wheelock et al 2010;Mylostyvyi et al 2021b).…”

Changes in the Spectrum of Free Fatty Acids in Blood Serum of Dairy Cows during a Prolonged Summer Heat Wave

“…In particular, saturated fatty acids (SFA) are a source of energy and play an important role in the prevention of lipid oxidation of cell membranes. Polyunsaturated fatty acids (PUFA), which are part of biomembrane phospholipids, provide not only their structure but also regulate intracellular metabolism and create optimal conditions for the activity of multienzyme systems [ 1 , 2 ]. Separate FAs are precursors of many biologically active substances (prostaglandins, leukotrienes, thromboxanes, and many others) involved in the regulation of metabolic processes in humans and animals.…”
