A novel antihypertensive drug, LCZ696 (Entresto(®) ), has recently been introduced, which combines the action of an antagonist of the renin-angiotensin-aldosterone-system (RAAS), effectively decreasing the blood pressure, with an inhibition of neprilysin, which is responsible for metabolizing natriuretic peptides exerting anti-hypertensive and anti-fibrotic effects. In this MiniReview, we describe the pharmacokinetics and -dynamics, efficacy and side effects of the combined angiotensin receptor antagonist and neprilysin inhibitor LCZ696...

Icariin has previously been demonstrated to attenuate hyperglycemia‑induced renal injury, however the renoprotective effects of icariin in a rat model of pregnancy‑induced hypertension (PIH) remain to be elucidated. The present study aimed to investigate the effect of icariin on PIH‑induced acute kidney injury (AKI) and proteinuria. Following 18 days of icariin treatment between day 1 and day 18 of gestation, which was combined with NG‑nitro‑L‑arginine methyl ester (L‑NAME) treatment between day 12 and day 18 of gestation to induce PIH, the 24 h urine protein level, blood urea nitrogen and serum creatinine were measured by using the Coomassie Brilliant Blue method, a commercial enzymatic kit and the picric acid method, respectively...

Antiphospholipid (aPL) antibodies are antibodies specific for anionic phospholipids. They are immunoglobulins that attack phospholipids, phospholipid-binding proteins, or phospholipid-protein complexes and are detected in anticardiolipin and lupus anticoagulant assays. aPL antibodies are often associated with antiphospholipid syndrome (APS) which can be idiopathic or from secondary causes such as systemic lupus erythematosus (SLE), infection or drugs. They have also been shown to be associated with Pulmonary Hypertension...

The efficacy of oral acitretin in the systemic treatment of severe and recalcitrant dermatoses has been established in a large number of clinical trials. Its mucocutaneous and ocular adverse reactions are common or relatively common, whereas systemic side effects are either uncommon or rare and include teratogenesis, hyperlipidemia, hepatotoxicity, intracranial hypertension, myopathy, and peripheral neuropathy. Angioedema is a term used to describe an acute, solitary or multiple, circumscribed, and non-pitting mucocutaneous swelling that affects the dermis and the subcutaneous tissue, lasts 24 to 72 hours, and may become potentially life-threatening when the pharynx and/or the larynx are involved...

Antihypertensive drug adherence (ADA) is a mainstay in blood pressure control. Education through mobile phone short message system (SMS) text messaging could improve ADA. The authors conducted a randomized study involving 314 patients with hypertension with <6 months of antihypertensive treatment from the Preventive Health Program of 12 different primary care centers in Santiago, Chile. Patients were randomly assigned to receive or not receive SMS related to ADA and healthy lifestyle. Adherence was assessed by the self-reported four-item scale Morisky-Green-Levine questionnaire at baseline and after 6 months of follow-up, with four of four positive questions classified as good adherence...

We provide original, international evidence documenting that self-assessed health (SAH) is a leading health indicator, that is, a significant predictor of future changes in health conditions, in a large sample of Europeans aged above 50 and living in 13 different countries. We find that, after controlling for attrition bias, lagged SAH is significantly and negatively correlated with changes in the number of chronic diseases, net of the correlations with levels, and changes in sociodemographic factors and health styles, country and regional health system effects, and declared symptoms...

Seasonal variation in the incidence and cardiovascular disease complications in the general population has been well documented (1) . According to analysis of data from the United States Renal Data System (USRDS) of all prevalent end-stage kidney disease (ESKD) patients between 2000 and 2013, the transition to ESKD (i.e. initiation of renal replacement therapy) and the incidence of all-cause and cause-specific mortality in patients with ESKD were highest during winter months (particularly January) compared to summer months, suggesting the possibility of season-specific precipitants during winter months contributing to adverse outcomes in both the general population and in patients with ESKD (2) ...

Polarization dependence second harmonic generation (P-SHG) microscopy is gaining increase popularity for in situ quantification of fibrillar protein architectures. In this report, we combine P-SHG microscopy, new linear least square (LLS) fitting and modeling to determine and convert the complex second-order non-linear optical anisotropy parameter ρ of several collagen rich tissues into a simple geometric organization of collagen fibrils. Modeling integrates a priori knowledge of polyhelical organization of collagen molecule polymers forming fibrils and bundles of fibrils as well as Poisson photonic shot noise of the detection system...

Decha Pinkaew, Ken Fujise
Fortilin is a highly conserved 172-amino-acid polypeptide found in the cytosol, nucleus, mitochondria, extracellular space, and circulating blood. It is a multifunctional protein that protects cells against apoptosis, promotes cell growth and cell cycle progression, binds calcium (Ca(2+)) and has antipathogen activities. Its role in the pathogenesis of human and animal diseases is also diverse. Fortilin facilitates the development of atherosclerosis, contributes to both systemic and pulmonary arterial hypertension, participates in the development of cancers, and worsens diabetic nephropathy...

REVIEW
Costas Tsioufis, M D Costas Thomopoulos
Combination treatment of hypertension has been introduced almost 50 years ago, because of the marked blood pressure (BP) elevation of recruited patients in the early randomized controlled trials of BP lowering. However, in all subsequent trials combination treatment was per protocol anticipated irrespectively of the initial randomized treatment to ensure either a desirable BP lowering or a comparable level of BP reduction among arms. Beyond clinical trials, combination treatment is mainly used in the clinical practice to reinforce ongoing single-agent treatment to achieve hypertension control...

Background: Many studies have reported conflicting evidence on the association between weight change and mortality. Objective: We investigated the association between weight change and subsequent all-cause mortality, using a large-scale population-based cohort from the National Health Insurance System health checkup data between 2005 and 2015. Methods: A total of 11,524,763 subjects aged over 20 years were included. Weight was measured every two years and weight change over 4 years was divided into eight categories, from weight loss ≥15% to weight gain ≥20%, for every 5% of weight change...

Cardiovascular diseases are the number one cause of death globally with an estimated 7.4 million people dying from coronary heart disease. Studies have been conducted to identify the therapeutic utility of exosomes in many diseases, including cardiovascular diseases. It has been demonstrated that exosomes are immune modulators, can be used to treat cardiac ischemic injury, pulmonary hypertension and many other diseases, including cancers. Exosomes can be used as a biomarker for disease and cell-free drug delivery system for targeting the cells...

Aim: The hemodynamic response to mouse systemic anaphylaxis is characterized by an initial hypertension followed by sustained hypotension. However, the defense mechanisms of the sympathetic nervous system against this circulatory disturbance is not known. Here, we investigated the renal sympathetic nerve activity (RSNA) response to mouse systemic anaphylaxis, along with the roles of carotid sinus baroreceptor, vagal nerves and the transient receptor potential vanilloid type 1 channel (TRPV1). Methods: Male ovalbumin-sensitized C57BL/6N mice were used under pentobarbital anesthesia...

To assess whether high cerebral microbleeds (CMBs) are associated with carotid intima-media thickness (CIMT), a marker of systemic atherosclerosis, we cross-sectionally evaluated participants from a community-based study, the I-Lan Longitudinal Aging Study. The participants' demographics and cardiovascular risk factors were determined by questionnaire and/or laboratory measurements. CIMT was measured by ultrasonography. CMBs were assessed by susceptibility-weighted-imaging on 3 T MRI. Of the 962 subjects [62...

Targeting protein-protein interaction (PPI) is rapidly becoming an attractive alternative for drug development. While drug development commonly involves inhibiting a PPI, in this study, we show that stabilizing PPI may also be therapeutically beneficial. Junctional proteins Neph1 and ZO-1 and their interaction is an important determinant of the structural integrity of slit diaphragm, which is a critical component of kidney's filtration system. Since injury induces loss of this interaction, we hypothesized that strengthening this interaction may protect kidney's filtration barrier and preserve kidney function...

Heart rate variability (HRV) analysis is widely used to investigate the autonomic regulation of the cardiovascular system. HRV is often analyzed using RR time series, which can be affected by different types of artifacts. Although there are several artifact correction methods, there is no study that compares their performances in actual experimental contexts. This work aimed to evaluate the impact of different artifact correction methods on several HRV parameters. Initially, 36 ECG recordings of control rats or rats with heart failure or hypertension were analyzed to characterize artifacts occurrence rates and distributions, in order to be mimicked in simulations...
