PURPOSE: Rice bran protein hydrolysates (RBPH) contain highly nutritional proteins and antioxidant compounds which show benefits against metabolic syndrome (MetS). Increased arterial stiffness and the components of MetS have been shown to be associated with an increased risk of cardiovascular disease. This study aimed to investigate whether RBPH could alleviate the metabolic disorders, arterial stiffening, vascular remodeling, and oxidative stress in rats fed a high-carbohydrate and high-fat (HCHF) diet...

An animal-borne blood sampler with data logging functions was developed for phocid seals which collected two blood samples for the comparison of endocrinological/biochemical parameters under two different conditions. The sampler can be triggered by preset hydrostatic pressure, acceleration (descending or ascending), temperature and time, and also manually by light. The sampling was reliable with >78% successful attempts to collect blood samples. Contamination of fluids in the tubing to the next blood sample was <1%, following the prior clearance of the tubing to a waste syringe...

Recently, we have shown that high fat diet (HFD) in vivo and in vitro generates metabolic memory by altering H3K36me2 and H3K27me3 on the promoter of FOXO1 (transcription factor of gluconeogenic genes) (Kumar et al., 2015). Here we checked the hypothesis, whether concomitant diet reversal and metformin could overcome HFD-induced metabolic memory and renal damage. Male adult Sprague Dawley rats were rendered insulin resistant by feeding high fat diet for 16 weeks. Then the rats were subjected to diet reversal (REV) alone and along with metformin (REV+MET) for 8 weeks...

OBJECTIVE: The prevalence of hypertension in premenopausal women is increasing. There is substantial need for novel strategies to identify women who would benefit from increased screening and early interventions. Several mechanisms likely contributing to premenstrual syndrome (PMS) are also involved in hypertension, including renin-angiotensin-aldosterone system dysfunction and micronutrient deficiencies. However, it is unknown whether young women with PMS have elevated blood pressure...

The angiotensin-converting enzyme 2-angiotensin-(1-7)-MAS axis (ACE2-Ang-[1-7]-MAS axis) plays an important role in the control of blood pressure. Some previous studies indicated that the genetic variants of ACE2 may have a potential to influence this axis. Therefore, the present study aimed at examining the association of ACE2 polymorphisms with circulating ACE2 and Ang-(1-7) levels in patients with essential hypertension.Hypertensive patients who met the inclusion criteria were enrolled in the present study...

Metabolic syndrome (MetS) is associated with nephropathy. Along with common risk factors such as hypertension and hyperglycemia, adipocytokines released from perirenal adipose tissue (PRAT) are implicated in the pathogenesis of MetS nephropathy. The study was designed to elucidate the adverse effects of PRAT-derived leptin on nephropathy and to determine whether the angiotensin II type 1 receptor antagonist telmisartan exerts a renoprotective effect by decreasing the PRAT-derived leptin level in the high-fat diet-induced MetS rat...

Angiotensin receptor blockers may be an appropriate first-line agent for postmenopausal women with hypertension because the activation of renin-angiotensin-aldosterone system is suggested as one possible mechanism of postmenopausal hypertension. However, there are few studies substantiating this effect. This study aimed to investigate clinic and home blood pressure (BP) lowering effect of fimasartan, a new angiotensin receptor blocker, in postmenopausal women with hypertension.Among patients with hypertension enrolled in K-Mets Study, 1373 women with fimasartan as a first antihypertensive drug and 3-months follow-up data were selected...

BACKGROUND: Obesity substantially increases the risk of the development of chronic kidney disease. Adipose tissue expresses all of the components of the renin-angiotensin system (RAS), contributing to the high prevalence of hypertension in obese patients and driving renal hyperfiltration and subsequent glomerular injury. METHODS: We performed a retrospective cohort study using a United Kingdom primary care database, evaluating the effect of time-updated exposure to RAS blockade versus all other antihypertensive medications in obese, hypertensive, non-diabetic patients...

Olmesartan is one of the various angiotensin II antagonists currently used for the management of high blood pressure. A sprue-like enteropathy was first described in 2012 in association with this antihypertensive drug. An observational, descriptive study was carried out on a series of 12 patients who met the clinical, histopathological, and outcome criteria for olmesartan-related sprue-like enteropathy from May 2013 to December 2015. All patients had watery diarrhea, weight loss, and negative celiac serology...

BACKGROUND: Among patients with chronic heart failure, angiotensin-converting-enzyme (ACE) inhibitors reduce mortality and hospitalization, but the role of a renin inhibitor in such patients is unknown. We compared the ACE inhibitor enalapril with the renin inhibitor aliskiren (to test superiority or at least noninferiority) and with the combination of the two treatments (to test superiority) in patients with heart failure and a reduced ejection fraction. METHODS: After a single-blind run-in period, we assigned patients, in a double-blind fashion, to one of three groups: 2336 patients were assigned to receive enalapril at a dose of 5 or 10 mg twice daily, 2340 to receive aliskiren at a dose of 300 mg once daily, and 2340 to receive both treatments (combination therapy)...

Human dipeptidyl-peptidase III (hDPP III) is a zinc-dependent hydrolase cleaving dipeptides off the N-termini of various bioactive peptides. Thus, the enzyme is likely involved in a number of physiological processes such as nociception and is also implicated in several forms of cancer. We present high-resolution crystal structures of hDPP III in complex with opioid peptides (Met-and Leu-enkephalin, endomorphin-2) as well as with angiotensin-II and the peptide inhibitor IVYPW. These structures confirm the previously reported large conformational change of the enzyme upon ligand binding and show that the structure of the closed conformation is independent of the nature of the bound peptide...

Alport syndrome (AS) is a hereditary progressive glomerulonephritis with a high life-time risk for end-stage renal disease (ESRD). Most patients will reach ESRD before the age of 30 years, while a subset of them with milder mutations will do so at older ages, even after 50 years. Frequent extrarenal manifestations are hearing loss and ocular abnormalities. AS is a genetically heterogeneous collagen IV nephropathy, with 85% of the cases caused by mutations in the X-linked COL4A5 gene and the rest by homozygous or compound heterozygous mutations in either the COL4A3 or the COL4A4 gene on chromosome 2q36-37...
