Central Inhibition of Tumor Necrosis Factor Alpha Reduces Hypertension by Attenuating Oxidative Stress in the Rostral Ventrolateral Medulla in Renovascular Hypertensive Rats

In this study, spontaneous baroreflex sensitivity (SBRS) was also calculated through the sequence method by the computer software CardioSeries (v2.4). A baroreflex sequence was defined as a sequence of at least four heart beats in which both systolic arterial pressure and pulse interval increased (up sequences) or decreased (down sequences) as previously described (Braga et al., 2008). Evaluation of Sympathetic Tonus to the Vasculature In a separate group of rats, the sympathetic vascular tone was evaluated by an intravenous injection of hexamethonium (30 mg/Kg, Sigma-Aldrich, São Paulo, Brazil), a ganglionic blocker. The magnitude of the fall in blood pressure yield the contribution of the sympathetic tone to sustain blood pressure at baseline level. Power Spectral Analysis of Systolic Arterial Pressure Systolic arterial pressure (SAP) signals were evaluated by power spectral analysis. In our study, we were particularly interested in the low-frequency component of SAP signals (LF, 0.25–0.8 Hz), that is representative of the modulatory effects of sympathetic tone and was reported to take origin from the RVLM (Kuo et al., 1997). To reach this goal, beat-by-beat time series of SAP were extracted from baseline cardiovascular recordings (10 min epochs) of pulsatile arterial pressure of rats in each group and the variability of these series was assessed using Fast Fourier Transform spectral analysis (Cardioseries Software v2.4) (Tezini et al., 2013). Measurement ...

Authors: Bergland OU, Søraas CL, Larstorp ACK, Halvorsen LV, Hjørnholm U, Hoffman P, Høieggen A, Fadl Elmula FEM Abstract PURPOSE: The blood pressure (BP) lowering effect of renal sympathetic denervation (RDN) in treatment-resistant hypertension shows variation amongst the existing randomised studies. The long-term efficacy and safety of RDN require further investigation. For the first time, we report BP changes and safety up to 7 years after RDN, compared to drug adjustment in the randomised Oslo RDN study. MATERIALS AND METHODS: Patients with treatment-resistant hypertension, defined...

Authors: Zhang W, Xu JZ, Lu XH, Li H, Wang D, Wang JG Abstract PURPOSE: We hypothesise that dietary sodium intake interacts with serum uric acid to influence blood pressure (BP) in children and adolescents. In the present study, we investigated ambulatory BP in relation to hyperuricaemia, dietary sodium intake and their interaction in children and adolescents with hypertension. MATERIALS AND METHODS:  A total of 616 study participants were 10-24 years old and had primary hypertension diagnosed after admission in a specialised inpatient ward. Ambulatory BP monitoring was performed during hospitalisat...

This study investigated the factors associated with the nutritional status of school children in a rural municipality in Cebu, Philippines. Children aged 6-12 years (n = 327) and their parents were asked to participate. Children's anthropometric measurements were taken in schools, while interviews and measurements of parents were conducted at home. Children's nutritional status was assessed using height-for-age (HAZ) and weight-for-age (WAZ) z scores, while body mass index (BMI) was used for parents. Children's dietary patterns and physical activity, and household characteristics, such as food insecurity, eating ...

Authors: Siamashvili M, Davis S Abstract INTRODUCTION: Bromocriptine mesylate quick release (QR) is a dopamine D2 receptor agonist and is the only oral, primarily centrally acting drug that can be used for the treatment of adults with type 2 diabetes. AREAS COVERED: The authors describe current recommendations on the use of bromocriptine mesylate QR. Major efficacy and safety parameters of the late phase trials, including The Cycloset Safety Trial, have been identified and presented. EXPERT OPINION: Efficacy of bromocriptine mesylate QR monotherapy appears to be low but is compensated by favorable safety pr...
