1. The levels of oxidized and reduced pyridine nucleotides have been measured in normal and DDT- and DDE-treated nymphs and adult males of T. infestans. 2. The total content of DPN (DPN plus DPNH) is higher than TPN (TPN plus TPNH) in both nymphs and males. In nymphs, DPN is mainly present in the oxidized form and TPN in the reduced form, while in males TPN is mainly found in the reduced form and DPN in the oxidized form. 3. DDT significantly increases the total TPN content in nymphs, but does not ...

Induction of oxidative stress by 2,4-dichlorophenoxyacetic acid (2,4-D) both as a pure compound and in commercial formulation was investigated during early pregnancy in mice. Pregnant animals were exposed to increasing doses of the herbicide (0.01, 0.1 and 100 mg/kg/d) during gestation days 0–9, after which animals were euthanized and their blood analyzed for catalase activity, thiobarbituric acid reactive substances (TBARs) and total antioxidant capacity (TAC). Number of corpora lutea and uterine implantations ...

Abstract Methods are described for the separation of nondialyzable material with erythropoietic activity (urinary hemopoietine), from urine of rabbits made anemic (< 5g Hb/100) by phenylhydrazine and of patients with aplastic anemia (< 5g Hb/100). The material obtained was assayed for its effects on Fe59 distribution 3 and 24 hours after tracer injection. The active extracts produced a marked increase in the rate of Fe59 clearance from plasma, and in the fraction of the injected Fe59 appearing in erythrocytes ...

1. DDT and various compounds icnrease the in vivo concentration of NAD-kinase in T. infestants nymphs. On the other hand, other compounds are inhibitory. The effect of DDt is observed only with internal concentrations of approximately 15 μg, while lower concentrations inhibit the enzyme. NAD-kinase is induced more rapidly with DDD and DDT. The inductive effect is not permanent since, upon removal of DDT, NAD-kinase activity decreases. 2. The activation of NAD-kinase by DDT and some analogs as well ...

(1) Nymph and male T. infestans specimens differ in their rate of absorption, excretion and metabolism of C14-DDT. Nymphs absorb DDT to a lesser extent than males. Furthermore, DDT is excreted at a faster rate in nymphs than males. After 96 hours of intoxication, 27.5% of the absorbed DDT is converted to a mixture of five metabolites in nymphs, while only 4.7% of the absorbed DDT is accounted for by DDT-metabolites in males after the same time of intoxication. (2) DDT is metabolized into five metabolites ...

The Surface Immunogenic Protein (SIP) of Group B Streptococcus (GBS) had been described as a good target for vaccine development. To date, SIP has been reported as a highly conserved protein, and in a mouse model it induces protection against lethal GBS challenge. Also, similar effects have been described by intranasal immunization with a SIP-based vaccine. In this study, we show the immune response induced by an oral SIP-based vaccine formulated on alum in a mouse model. Our vaccine can reduce vaginal ...

Vaccine-induced protection against pathogens, especially subunit-based vaccines, are related to antigen properties but mainly in their ability to stimulate the immune system by the use of an adjuvant. Modern vaccines are formulated with a high level of antigen purity, where an efficient adjuvant is necessary. In this context, the use of protein Toll-Like Receptor (TLR) agonists as vaccine adjuvants has been highlighted because of their optimal immunogenicity and minimal toxicity. The Surface Immunogenic ...

Plant-microbiota interactions have significant effects on plant growth, health, and productivity. Rhizosphere microorganisms are involved in processes that promote physiological responses to biotic and abiotic stresses in plants. In recent years, the interest in microorganisms to improve plant productivity has increased, mainly aiming to find promising strains to overcome the impact of climate change on crops. In this work, we hypothesize that given the desertic environment of the Antarctic and ...

Hypomagnesemia (hypoMg) has not yet been extensively studied in alcohol use disorder (AUD) . We hypothesize that chronic, excessive alcohol consumption favors oxidative stress and pro-inflammatory alterations that may be exacerbated by hypoMg. The objective of this study was to analyze the prevalence and associations of hypoMg in AUD.Cross-sectional study in patients admitted for a first treatment of AUD in six tertiary centers between 2013 and 2020. Socio-demographic, alcohol use characteristics, and ...

Recent evidence suggests that iron in human milk has a high bio-availability and that breast fed term infants are protected from developing iron deficiency during the first 6 months of life. Iron nutrition was determined in healthy term infants of low socioeconomic condition receiving breast milk as the only milk source for 4, 6 and 9 months (60, 70 and 31 subjects respectively) and compared with infants fed non fortified cow's milk. At 4 months, breast fed infants had a better iron nutrition status ...

However, there is ...
