SummaryIn human platelets the selenoenzyme glutathione peroxidase (GSH-Px) acts as a scavenger of the peroxides generated during the burst of arachidonic acid (AA) metabolism. Such a mechanism inhibits the biosynthesis of both thromboxane A2 (TXA2) and lipoxygenase products. The same mechanism is not effective on the prostacyclin (PGI2) biosynthesis from cultured endothelial cells. In order to evaluate this effect in vivo, besides in vitro, we activated the enzyme in eight normal volunteers by increasing their daily Se intake for 8 weeks, monitoring: platelet GSH-Px activity, platelet aggregat

Recent literature data on the effects of Se on subpopulations of T lymphocytes, on autologous mixed lymphocyte reaction (AMLR) and on natural killer (NK) cell cytotoxicity are limited or poorly defined. In healthy volunteers we have estimated se levels, glutathione peroxidase (GSH-Px) activity and lipid peroxide levels in human plasma and simultaneously, the subpopulations of T lymphocytes, proliferation in AMLR, and activity of NK cells. We found a significantly positive correlation between the selenium level and GSH-Px activity. The proliferative response in AMLR significantly correlated wit

Streszczenie:

The metabolism of oxygen in aerobic organisms leads to generation of reactive oxygen species (ROS). These entities are able to oxidize almost all classes of macromolecules, including proteins, lipids and nucleic acids. The physiological level of ROS is usually regulated by antioxidant defense mechanisms. There are at least three groups of antioxidant enzymes: superoxide dismutases, catalases and glutathione peroxidases (GSH-Pxs) which neutralize ROS. The trace elements (copper, zinc and selenium) bound to the active sites of the above listed enzymes play an important role in the antioxidant de

The model group was given continuous intraperitoneal injection of D-galactose solution (120 mg/kg/d) combined with aluminum trichloride (10 mg/kg/d) by gavage for 60 days. Morris water maze test was conducted to test the learning and memory abilities of the rats, and AD rats were selected. After modeling, AD rats were divided into a normal sali

Brazil is the world's second largest producer of tobacco (Nicotiana tabacum) with part of its production concentrated in Santa Catarina. The incidence of Sclerotinia sclerotiorum in tobacco areas has promoted a decrease in productivity, and control alternatives are needed due to the limited use of agrochemicals for the crop. With the hypothesis that the sudan grass (Sorghum sudanense) and Trichoderma harzianum reduce the attack of S. sclerotiorum in tobacco crops on the coast of Santa Catarina; the objective here was to test the incidence of S. sclerotiorum and the use of sudan grass associate

Cadmium (Cd) is a pollutant toxic to plants and a potential threat to human health. Selenium (Se), though not essential for plants, has beneficial effects on plants under abiotic stress. A hydroponic experiment was conducted to investigate the impact of different forms of Se (Nano-Se, selenite, selenate, and SeMet) on accumulation, subcellular distribution, and chemical forms of Cd, as well as oxidative stress in rice seedlings. Cd (20 μmol·L−1) treatment significantly decreased biomass accumulation and chlorophyll content. The application of all Se forms, except selenate, mitigated the advers

Abstract Tobacco smoke both has a somatic mutagenic effect and also alters the physiology and microenvironment within the lung. Physiological effects likely influence the extent to which mutations confer proliferative or survival advantages underlying oncogenesis. However, the contributions of these mutagenic and physiological effects to oncogenesis have not previously been quantified. Because the efficacy of such therapies is dependent on the adaptive benefit conferred by the targeted mutations, this quantification is crucial for the development, testing, and application of targeted therapeut

Pollen germination in vivo on wet stigmas is assisted by the receptive fluid—stigma exudate. Its exact composition is still unknown because only some components have been studied. For the first time, hormonal screening was carried out, and the fatty acid (FA) composition of lipid-rich (Nicotiana tabacum) and sugar-rich (Lilium longiflorum) exudates was studied. Screening of exudate for the presence of plant hormones using HPLC-MS revealed abscisic acid (ABA) in tobacco stigma exudate at the two stages of development, at pre-maturity and in mature stigmas awaiting pollination, increasing at the

The viral disease caused by tobacco mosaic virus (TMV) is the most prevalent viral disease in many tobacco production areas. A breeding strategy based on resistance genes is an effective method for improving TMV resistance in tobacco. Also, the physiological status of plants is also critical to disease resistance improvement. Potassium ion is one of the most abundant inorganic nutrients in plant cells, and mediates plant responses to abiotic and biotic stresses. Improving K+ content in soil by fertilising can enhance diseases resistance of crops. However, the K+ absorption in plants depends mo

Background: Osmotin-Like Proteins (OLPs) have been purified and characterized from different plant tissues, including latex fluids. Besides its defensive role, tobacco osmotin seems to induce adiponectin-like physiological effects, acting as an agonist. However, molecular information about this agonistic effect on adiponectin receptors has been poorly exploited and other osmotins have not been investigated yet. Objective and Methods: The present study involved the characterization of three OLPs from Plumeria rubra latex and molecular docking studies to evaluate the interaction between them and
