It has been acknowledged since ancient times that milk and dairy products have a vital role in nutrition and contribute considerably to human health. Because of its content, Because of its content, it has many important effects on the life that include immuno‐ globulins, enzymes, hormones, growth factors, antibacterial agents, fat acids, vita‐ mins, and minerals. Approximately 70 indigenous enz...
Determination of reliable bioindicators of diabetes-induced oxidative stress and the role of dietary vitamin E supplementation were investigated. Blood (plasma) chemistries, lipid peroxidation (LPO), and antioxidant enzyme activities were measured over 12 weeks in New Zealand White rabbits (control, diabetic, and diabetic + vitamin E). Cholesterol and triglyceride levels did not correlate with ...
Elasticity measurements of bilayer lipid membranes (BLM) based on registration of the third harmonic of the membrane current during the application of a periodic tension to the membrane was used to study the effects of lipid peroxidation (LPO) and phospholipase A on BLM. LPO resulted in decreased values of the Young modulus for BLM, while some products of LPO and phospholipid hydrolysis (linole...
Lipid peroxidation (LPO) product accumulation in human tissues is a major cause of tissular and cellular dysfunction that plays a major role in ageing and most age-related and oxidative stress-related diseases. The current evidence for the implication of LPO in pathological processes is discussed in this review. New data and literature review are provided evaluating the role of LPO in the patho...
background: lactoperoxidase (lpo) is one of the most heat-stable enzymes in milk and its inactivation has been proposed for monitoring thermal processes. the aim of this study was to provide information on activity and thermal inactivation behavior of lpo in iranian cow and buffalo milk and whey. methods: sixty cow and buffalo milk samples were collected. the lpo activity was measured using spe...
objective(s): enzyme immobilization via nanoparticles is perfectly compatible against the other chemical or biological approximate to improve enzyme functions and stability. in this study lactoperoxidase was immobilized onto silica-coated magnetite nanoparticles to improve enzyme properties in the presence of cadmium chloride as an inhibitor. materials and methods: the process consists of the ...
The formation of Lewy bodies containing α-synuclein (α-syn), prominent loss of dopaminergic neurons and dopamine (DA) deficiency in substantia nigra and striatum are histopathological and biochemical hallmarks of Parkinson's disease (PD). Multiple lines of evidence have indicated that a critical pathogenic factor causing PD is enhanced production of reactive oxygen species (ROS), which reacts r...
BACKGROUND This work aims to investigate the role of lipid peroxidation (LPO) at early stages of liver regeneration and to evaluate the balance between apoptosis and cell proliferation during this process. METHODS Sham and partial hepatectomized (PH) male Wistar rats were randomized in seven groups: Control (untreated), E-Control (injected with vitamin E-vehicle), C-Control (injected with vit...
Practical techniques for designing transfer trajectories between Libration Point Orbits (LPOs) are presented. Motivation for development of these techniques was provided by a hardware contingency experienced by the Solar Heliospheric Observatory (SOHO), a joint mission of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) orbiting the L1 point of the Su...
Many thermal runaway incidents have been caused by organic peroxides due to the peroxy group, -O-O-, which is essentially unstable and active. Lauroyl peroxide (LPO) is also sensitive to thermal sources and is incompatible with many materials, such as acids, bases, metals, and ions. From the thermal decomposition reaction of various concentrations of nitric acid (HNO3) (from lower to higher con...
