Background: Evidence suggests that bioactive peptides reduce hypertension and affect certain metabolic pathways.
Methods: Fifty-four volunteers with stage 1 prehypertension and/or hypercholesterolemia and/or basal glucose >100 mg/dL were recruited and randomized to pork dry-cured ham ( = 35) or cooked ham (placebo group; = 19) for 28 days. After a wash-out period, meat products were changed for 28 additional days.
Background: Acute kidney injury (AKI) is a serious complication in patients hospitalized for decompensated heart failure (HF). Currently, AKI definitions consider creatinine levels at admission as reference of baseline renal function (RF). However, renal impairment may already be present at admission.
View Article and Find Full Text PDFOxylipins such as isoprostanes (IsoPs), prostaglandins (PGs) and thromboxanes (TXs) are lipid mediators derived from the oxidation of polyunsaturated fatty acids, which regulate the magnitude of oxidative stress and inflammation processes and play an important role in pathophysiological processes in the kidney. A total of 36 oxylipins were analyzed by UHPLC-QqQ-MS/MS in the urine of 41 renal recipients from cadaveric donors of the Nephrology Unit of the University Hospital Virgen de la Arrixaca during the first six months after renal transplantation, in order to investigate several candidate oxylipins as more accurate and predictive biomarkers in renal transplantation than classical biological variables. A decrease in nine PGs, mostly from the AA-D pathway (p < 0.

We analyzed biomarkers of lipid peroxidation of the nervous system -F-dihomo-isoprostanes, F-neuroprostanes, and F-neuroprostanes- in urine samples from 158 healthy volunteers ranging from 4 to 88 years old with the aim of analyzing possible associations between their excretion values and age (years). Ten biomarkers were screened in the urine samples by UHPLC-QqQ-MS/MS. Four F-dihomo-isoprostanes (ent-7-(R)-7-F-dihomo-isoprostane, ent-7-epi-7-F-dihomo-isoprostane, 17-Fdihomo-isoprostane, 17-epi-17-F-dihomo-isoprostane), and one DPA-neuroprostane (4-F-neuroprostane) were detected in the samples.

This randomized and controlled trial investigated whether the increase in elite training at different altitudes altered the oxidative stress biomarkers of the nervous system. This is the first study to investigate four F4-neuroprostanes (F4-NeuroPs) and four F2-dihomo-isoprostanes (F2-dihomo-IsoPs) quantified in 24-h urine. The quantification was carried out by ultra high pressure liquid chromatography-triple quadrupole-tandem mass spectrometry (UHPLC-QqQ-MS/MS).

The test's usefulness may be greatest in patients with severe dyspnea of uncertain origin. However, NTproBNP has not been evaluated specifically in this setting.
