(Veterinary and Human Toxicology, 1997-02-01) [Artigo]
The presence of the pyrethroid insecticides flumethrin, deltamethrin, cypermethrin and cyhalothrin in milk and blood of 10 cows was determined after single dermal applications of recommended doses. Milk and blood samples ...
Effects of elevated calcium on motor and exploratory activities of rats
(Brazilian Journal of Medical and Biological Research, 2002-04-01) [Artigo]
The effects of serum and brain calcium concentration on rat behavior were tested by maintaining animals on either distilled water (N = 60) or water containing 1% calcium gluconate (N = 60) for 3 days. Animals that were ...

Metalloproteinase inhibition protects against reductions in circulating adrenomedullin during lead-induced acute hypertension
(Basic & Clinical Pharmacology & Toxicology, 2015-06-01) [Artigo]
Intoxication with lead (Pb) results in increased blood pressure by mechanisms involving matrix metalloproteinases (MMPs). Recent findings have revealed that MMP type two (MMP-2) seems to cleave vasoactive peptides. This ...
Correlations among antiangiogenic factors and trace elements in hypertensive disorders of pregnancy
(Journal Of Trace Elements In Medicine And Biology, 2015-01-01) [Artigo]
Although a number of studies have measured circulating levels of some trace elements in preeclampsia (PE) and compared to healthy pregnant (HP), there is no consensus yet about the deficiency of some metals and development ...
Circulating heme oxygenase-1: Not a predictor of preeclampsia but highly expressed in pregnant women who subsequently develop severe preeclampsia
(Oxidative Medicine and Cellular Longevity, 2018-01-01) [Artigo]
Preeclampsia is the major cause of maternal and fetal deaths worldwide. Circulating biomarker concentrations to predict preeclampsia must be determined. Therefore, the objective was to evaluate heme oxygenase-1 (HO-1) ...
