INTRODUCTION There are few studies indicating a relationship between vitamin D, parathyroid hormone (PTH), and parameters of endothelial function. OBJECTIVES The aim of the study was to establish the relationship between vascular endothelial function and the level of vitamin D and PTH in women with arterial hypertension (AH). PATIENTS AND METHODS It was a cross-sectional study of 141 women ...

Zinc or L-NAME administration has been shown to be protector agents, decreasing oxidative stress and cell death. However, the treatment with zinc and L-NAME by intraperitoneal injection has not been studied. The aim of our work was to study the effect of zinc and L-NAME administration on nitrosative stress and cell death. Male Wistar rats were treated with ZnCl2 (2.5 mg/kg each 24 h, for 4 days...

BACKGROUND The interaction of asbestos with macrophages drives two key processes that are linked to malignancy: (1) the generation of reactive oxygen species (ROS)/reactive nitrogen species (RNS) and (2) the activation of an inflammation cascade that drives acute and chronic inflammation, with the NLRP3 inflammasome playing a key role. Synthetic secoisolariciresinol diglucoside (SDG), LGM2605, ...

Urinary tract infection is a commonly encountered problem in clinical practice. Diagnosis is usually reached by considering compatible symptoms, microscopy and culture of urine samples. We carried out a retrospective study of records of patients established to have urinary tract infection at King Khalid University Hospital, Riyadh. The results showed the infection predominantly occurring in fem...

Objective. To evaluate the impact of oxidative stress on vascular reactivity to vasoconstrictors and on nitric oxide (NO) bioavailability in saphenous vein (SV) graft with endothelial dysfunction from hypertensive patients (HT). Methods. Endothelial function, vascular reactivity, oxidative state, nitrites and NO release were studied in isolated SV rings from HT and normotensive patients (NT). O...

The content of chlorides, nitrites, nitrates, phosphates and sulphates was used to classify 45 donkey's milk samples collected from different Italian regions. A method employing ion exchange chromatography with conductivity detector and chemical suppression was used. The quantitative results indicated phosphates (569.4-1304.4 mg kg(-1)) and chlorides (545.9-1757.9 mg kg(-1)) as being the most a...

The spontaneous non obese diabetic (NOD) mouse model of Sjögren's syndrome provides a valuable tool to study the onset and progression of both autoimmune response and secretory dysfunction. Vasoactive intestinal peptide (VIP) is a neuro and immunopeptide with prosecretory effect in salivary glands and anti-inflammatory actions in various models of autoimmune disease. Our purpose was to analyze ...

Hydrotalcite-supported Pd/Sn catalysts with different Mg/Al atomic ratios (2, 3, 4, and 5) for nitrate adsorption and hydrogenation reduction were successfully synthesized by a coprecipitation method. The results showed that different atomic ratios of Mg/Al resulted in different interlayer spacings and zeta-potentials of the catalysts, which thus influenced its adsorption capacity. With the inc...

The protective effect of therapeutic hypothermia in cardiac arrest survivors (CAS) has been previously well documented. Animal studies have indicated that attenuation of tissue oxidative stress (OS) may be involved in the mechanisms that lead to the beneficial effect of hypothermia. The extent of OS and nitric oxide (NO) production in adult CAS treated with endovascular hypothermia is, however,...

BACKGROUND Portal hypertension is a clinical syndrome associated with the development of a hyperdynamic circulation and gastroesophageal varices. Aim. To evaluate the antioxidant effect of N-acetylcysteine on portal hypertensive rats. MATERIAL AND METHODS Portal hypertension was induced by partial portal vein ligation (PPVL). Oxidative damage in the stomach was measured by lipoperoxidation tr...
