Corresponding Author: Julio C.M. Soares Universidade Federal do PampaUNIPAMPA-Campus de Caçapava do Sul, RS, Brazila Email: [email protected] Abstract: The intensification of the use of artificial insemination in the swine industry has increased the interest to develop proper conditions to store semen better for longer periods of time without affecting its fertility. Trolox is a vitamin E ...
177 xxx They analyzed 651 patients with APL of whom 72 expressed CD56 (11%). CD56 + APL was significantly associated with high white blood cell counts, low albumin levels, the BCR3 isoform and coexpression of the CD2, CD34, CD7, HLA-DR, CD15 and CD117 antigens. For CD56 + APL, the 5-year relapse rate was 22% compared with a 10% relapse rate for CD56-APL (p-value = 0.006). CD56 + APL also showed...
Immune system functioning and maintenance entails costs which may limit investment into other processes such as reproduction. Yet, the proximate mechanisms and 'currencies' mediating the costs of immune responses remain elusive. In vertebrates, up-regulation of the innate immune system is associated with rapid phagocytic production of pro-oxidant molecules (so-called 'oxidative burst' responses...
Cities may expose wild animals to new types of selection pressures, potentially leading to differentiation among urban and rural populations. One cellular mechanism likely important in determining the viability of vertebrate populations is resistance to oxidative stress, as tissue degradation resulting from oxidative stress may decrease reproductive performance and survival. We hypothesized tha...
Human population varies with regard to the rate of drug metabolism. Differences in pharmacological activity of a drug in patients who belong to the same population result from a different enzymatic activity and different genotypes of those subjects. The aim of the study was to assess the incidence of extensive (EM) and poor (PM) oxidative phenotypes in related persons and to establish whether a...
To re-examine the correlation between mtDNA variability and longevity, we examined mtDNAs from samples obtained from over 2200 ultranonagenarians (and an equal number of controls) collected within the framework of the GEHA EU project. The samples were categorized by high-resolution classification, while about 1300 mtDNA molecules (650 ultranonagenarians and an equal number of controls) were com...
background: oxidative stress reflects an imbalance between the reactive oxygen species (ros) and a biological system's ability to readily detoxify the oxidative agents. disturbances in the normal redox state of cells can cause toxic effects through production of peroxides and free radicals that damage all components of the cell, including proteins, lipids, and dna. objectives: the purpose ...
