BACKGROUND: In patients with left ventricular heart failure (HF), the development of pulmonary hypertension (PH) is common and represents a strong predictor of death. Despite recent advances in the pathophysiological understanding there is as yet no prospect of cure of this deadly clinical entity and the majority of patients continue to progress to right ventricular failure and die. Furthermore, there is no single medical treatment currently approved for PH related to HF. There is, therefore an urgent unmet need to identify novel pharmacological agents that will prevent the progressive increased or reverse the elevated pulmonary arterial pressures while enhancing cardiac performance in HF...

Previous studies have demonstrated associations of perfluoroalkyl substances (PFASs), a group of highly persistent chemicals ubiquitous in wildlife and humans, with hypertension, but the relationships are mixed. Furthermore, academic literature on the relationship between isomers of PFASs and blood pressure (BP) and hypertension in populations from a higher pollution area is scant. We studied 1612 Chinese adults, ages 22-96years old, from Shenyang, China, utilizing high performance liquid chromatography-mass spectrometry to analyze isomers of perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), and other PFASs in blood serum...

BACKGROUND/AIMS: The enhanced proliferation of pulmonary arterial smooth muscle cells (PASMCs) is a central pathological component in pulmonary arterial hypertension (PAH). Both the Warburg effect and platelet-derived growth factor (PDGF) are involved in the proliferation of PASMCs. However, the mechanism underlying the crosstalk between the Warburg effect and PDGF during PASMC proliferation is still unknown. We hypothesized that PDGF promotes the Warburg effect via activating the phosphatidylinositol 3-kinase (PI3K) signaling pathway and hypoxia-inducible factor 1-α (HIF-1α) in proliferative PASMCs...

Hyperhomocysteinemia is a risk factor for adverse cardiovascular events; however, the mechanism for development of this disease is still unknown. Toll-like receptor 4 is a molecule involved in the immune response pathway and is quickly becoming a receptor of interest in the field of hypertension. In this study, we hypothesized that ablation of TLR4 mitigates cardiac mitochondrial dysfunction in a model of hyperhomocysteinemia. Five strains of mice (C57BL/6J, CBS+/-, C3H, CBS+/-/C3H and C3H/HeOuJ) 10-12 weeks old were utilized...

Pheochromocytoma is a rare tumor which is infrequent in children. Although the clinical presentation in children can be atypical, the classic symptoms are headache, sweating and tachycardia. Hypertension is often a constant sign in most patients. There are few cases in literature reporting pheochromocytoma presented with polyuria. We present a 13-year-old girl who came to the Pediatric Nephrologist due to a year of evolution of secondary enuresis. When her blood pressure was taken, she was above the 99th percentile that corresponds to her age and her height that is why she was admitted for treatment and diagnostic study...

REVIEW
Larisa Simonca, Robert Tulloh
Pulmonary arterial hypertension (PAH) management has been transformed in recent times with the advent of cheap and effective diagnostic tools and therapy. Sildenafil, a phosphodiesterase-V inhibitor, has been at the centre of this treatment, and its success in treating PAH has led to its widespread uptake in adult and paediatric pulmonary hypertension (PH), as a first line treatment choice. This might apply to persistent pulmonary hypertension of the newborn (PPHN) or bronchopulmonary dysplasia, as well as to more complex diseases, such as idiopathic pulmonary hypertension...

Renin angiotensin aldosterone system (RAAS) plays an essential role in the homeostatic control of arterial blood pressure, perfusion of tissues, and control of extracellular fluid. Its components are highly expressed in the developing kidney, general vasculature, brain, and heart. A modified intrauterine environment alters mechanisms controlling blood pressure (BP) and can lead to hypertension in the adult offspring and developmentally programmed RAAS can be involved in this process. There are very little data about the effects of increased angiotensin II (Ang II) concentrations during pregnancy on in utero development of the fetus...
