Fragile Histidine Triad (FHIT), a Novel Modifier Gene in Pulmonary Arterial Hypertension.

Pulmonary arterial hypertension (PAH) is characterized by progressive narrowing of pulmonary arteries resulting in right heart failure and death. Bone Morphogenetic Protein Receptor type-2 (BMPR2) mutations account for most familial PAH (FPAH) forms while reduced BMPR2 is present in many idiopathic PAH (IPAH) forms, suggesting dysfunctional BMPR2 signaling to be a key feature of PAH. Modulating BM...

Testosterone plays a permissive role in angiotensin II-induced hypertension and cardiac hypertrophy in male rats.

Sex hormone-dependent vascular reactivity is an underlying factor contributing to sex differences in blood pressure. Inappropriate activation of the renin-angiotensin system (RAS) is involved in vascular dysfunction and hypertension. This study evaluated the role of androgens (testosterone) in angiotensin II (Ang II) -induced increase in blood pressure, vascular reactivity and cardiac hypertrophy....

How to Treat Hypertension in Venlafaxine-Medicated Patients-Pharmacokinetic Considerations in Prescribing Amlodipine and Ramipril.

Amlodipine (AMLO) and ramipril (RAMI) belong to the most prescribed drugs in patients with hypertension, a condition also encountered in depression. Venlafaxine may worsen hypertension because of noradrenergic properties. Although of special clinical relevance, data on pharmacokinetic interactions between AMLO, RAMI, and venlafaxine (VEN) are lacking.

Dietary calcium intake and hypertension risk: a dose-response meta-analysis of prospective cohort studies.

The association of calcium intake with risk of developing hypertension in the general population has not been established yet. We systematically searched PubMed and Scopus databases up to February 2018 to find prospective observational studies investigating the association of calcium intake with risk of developing hypertension. The reported risk estimates were pooled using a random-effects model. ...

Efficacy of treprostinil in the SU5416-hypoxia model of severe pulmonary arterial hypertension: hemodynamic benefits are not associated with improvements in arterial remodelling.

Pulmonary arterial hypertension (PAH) is a life-threatening disease that leads to progressive pulmonary hypertension, right heart failure and death. Parenteral prostaglandins, including treprostinil, a prostacyclin analogue, represent the most effective medical treatment for severe PAH. We investigated the effect of treprostinil on established severe PAH and underlying mechanisms using the rat SU5...

Association of single nucleotide polymorphisms of LEPR gene with essential hypertension among ethnic Mongolian and Han Chinese from Inner Mongolia region.

To assess the association of single nucleotide polymorphisms (SNPs) of leptin receptor (LEPR) gene with essential hypertension (EH) and body mass index (BMI) among ethnic Mongolian and Han Chinese from Inner Mongolia region.

Progress in genetic research on primary pulmonary hypertension.

Primary pulmonary hypertension (PPH) consisting of hereditary pulmonary arterial hypertension and idiopathic pulmonary arterial hypertension is an obstructive pulmonary hypertension caused by primary pulmonary artery hyperplasia. Both environmental and genetic factors are involved in the pathogenesis of PPH. Genes associated with TGF-β signaling pathway including BMPR2, ALK1, ENG, SMAD8 and other...

Intermittent low-level lead exposure provokes anxiety, hypertension, autonomic dysfunction and neuroinflammation.

Exposures to lead (Pb) during developmental phases can alter the normal course of development, with lifelong health consequences. Permanent Pb exposure leads to behavioral changes, cognitive impairment, sympathoexcitation, tachycardia, hypertension and autonomic dysfunction. However, the effects of an intermittent lead exposure are not yet studied. This pattern of exposure has been recently increa...

Evaluation of the antihypertensive effect of nocturnal administration of acetylsalicylic acid: a cross-over randomized clinical trial.

Several studies have shown that evening intake of aspirin has antihypertensive effect in healthy adults, which has not been proven in patients with cardiovascular disease, who mostly take aspirin in the morning. We have evaluated the antihypertensive effect of bedtime administration of aspirin in patients with cardiovascular disease already treated for hypertension.

Timing of Delivery in Women With Chronic Hypertension.

To assess whether routine induction of labor at 38 or 39 weeks in women with chronic hypertension is associated with the risk of superimposed preeclampsia or cesarean delivery.

Regulation of sympathetic vasomotor activity by the hypothalamic paraventricular nucleus in normotensive and hypertensive states.

The hypothalamic paraventricular nucleus (PVN) is a unique and important brain region involved in the control of cardiovascular, neuroendocrine, and other physiological functions pertinent to homeostasis. The PVN is a major source of excitatory drive to the spinal sympathetic outflow via both direct and indirect projections. In this review, we discuss the role of the PVN in the regulation of sympa...

A case of a lumbar schwannoma presenting with isolated signs and symptoms of intracranial hypertension.

Hydrocephalus and intracranial hypertension are rare signs of spinal tumors when presenting in isolation, particularly with benign tumors.

Metabolomic study for essential hypertension patients based on dried blood spot mass spectrometry approach.

Hypertension is an increasingly serious public-health challenge worldwide. The traditional blood pressure measurement method could easily and reliably detect blood pressure. However, the delayed symptom onset may influence the screening of essential hypertension (EH). In addition, EH is significantly associated to cardiovascular disease, stroke and kidney disease. Hence, it is urgent to define ass...

Combination therapies for hypertension - why we need to look beyond RAS blockers.

Hypertension is the leading cause of mortality and disability worldwide. Despite the proven benefits of blood pressure (BP) reduction, lack of BP pressure control continues to be the most important clinical problem in hypertension management. Areas covered: Factors involved in the lack of BP control and strategies to improve such control have been reviewed, with special focus on the usefulness of ...

Identification of essential hypertension biomarkers in human urine by non-targeted metabolomics based on UPLC-Q-TOF/MS.

In recent years, using metabolomics technology to study hypertension has made some progress. However, in actual clinical studies, there are few studies on hypertension related metabonomics with human urine as samples. In this study, the urine samples of patients with essential hypertension (EH) were studied by comparing with healthy people to explore the changes of urine metabolites between hypert...

Smooth muscle cell-specific FoxM1 controls hypoxia-induced pulmonary hypertension.

Forkhead box M1 (FoxM1) is a transcription factor that promotes cell proliferation by regulating a broad spectrum of genes that participate in cell cycle regulation, such as Cyclin B, CDC25B, and Aurora B Kinase. We have shown that hypoxia, a well-known stimulus for pulmonary hypertension (PH), induces FoxM1 in pulmonary artery smooth muscle cells (PASMC) in a HIF-dependent pathway, resulting in P...

A randomized controlled crossover trial evaluating differential responses to antihypertensive drugs (used as mono- or dual therapy) on the basis of ethnicity: The comparIsoN oF Optimal Hypertension RegiMens; part of the Ancestry Informative Markers in HYpertension program-AIM-HY INFORM trial.

Ethnicity, along with a variety of genetic and environmental factors, is thought to influence the efficacy of antihypertensive therapies. Current UK guidelines use a "black versus white" approach; in doing so, they ignore the United Kingdom's largest ethnic minority: Asians from South Asia.
