Previously, we have demonstrated that the seeds of Euterpe oleracia Mart. (açaí) are rich in polyphenols with antihypertensive and antioxidant properties. This study evaluated the renal protective effects of the hydroalcoholic extract obtained from the seeds of açaí (ASE) fruits in two-kidney, one-clip (2K1C) renovascular hypertension. Young male Wistar rats were used to obtain 2K1C and sham groups. Animals received ASE (200 mg/(kg·day) in drinking water) or vehicle for 40 days. We evaluated serum and urinary parameters, renal structural changes, and oxidative status...

BACKGROUND: Nephrotoxicity side effect of the immunosuppressive drug, cyclosporine A (CsA), can be a major issue in transplantation medicine. Cyclosporine A-induced nephrotoxicity is multifactorial but oxidative stress has a critical role in this process. It has been demonstrated that Valsartan (Val) as an angiotensin receptor blocker has renoprotective effects, but the molecular mechanisms responsible for the renal protection, independent from its blood pressure lowering effect, have not yet been fully understood...

Resistin acts centrally to increase renal sympathetic nerve activity (RSNA). This is similar to leptin. In high fat fed animals, the sympatho-excitatory effects of leptin are retained, in contrast to the reduced actions of leptin on dietary intake. In the present study we investigated whether the sympatho-excitatory actions of resistin were influenced by a high fat diet. Further, since resistin and leptin combined can induce a greater sympatho-excitatory response than each alone in rats fed a normal chow diet, we investigated whether a high fat diet (22%) could influence this centrally mediated interaction...

Total flavonoids of Humulus lupulus (TFHL) were prepared using ethanol extraction, liquid-liquid partition and purification with polyamide resin. Different dose of TFHL were orally administered to normal and hyperuricemic mice for 7 days. The xanthine oxidase (XOD) inhibitory activity and hypouricemic effects of TFHL on potassium oxonate-induced hyperuricemic mice were examined. The TFHL showed very potent XOD inhibitory activity with IC50=66.8 μg/mL. At a single oral dose of 100mg/kg TFHL, the serum uric acid levels of hyperuricemic mice significantly decreased (P<0...

Non-steroidal anti-inflammatory drugs (NSAIDs) consumption has been commonly associated with gastric mucosal lesions including gastric ulcer. Silymarin (SM) is a flavonoid mixture with anti-oxidant and anti-inflammatory activities which explain its protective role against hepatic and renal injuries. However, its impact on gastric ulcer has not yet been elucidated. Thus we went further to investigate the potential protective effects of SM against indomethacin-induced gastric injury in rats. Pretreatment with SM (50 mg/kg orally) attenuated the severity of gastric mucosal damage as evidenced by decreasing ulcer index (UI) and ulcer score, improvement of disturbed histopathologicl features to be insignificant with those induced by the reference anti-ulcer drug...

AIMS/INTRODUCTION: Diabetic nephropathy is one of the leading causes of end-stage renal disease. Unfortunately, reliable surrogate markers for predicting the prognostic outcome of diabetic nephropathy were as yet absent. In order to find new markers in predicting the progression of diabetic nephropathy, we conducted a prospective study by investigating the correlation between serum metabolites and the annual change of estimated glomerular filtration rate (eGFR). MATERIALS AND METHODS: From September 2013 to September 2015, 52 diabetic patients at various stages of chronic kidney disease (CKD) were enrolled...

Solid organ transplant patients are at an increased risk of developing cutaneous malignancies owing to long-lasting immunosuppression. The strongest increase in incidence (35-fold) has been reported for cutaneous squamous cell carcinoma [1]. Basal cell carcinoma (BCC) may occur even more frequently, especially during the first years after transplantation [2]. The hedgehog-inhibitor vismodegib has been safely used for the treatment of locally advanced or metastatic BCC in immunocompetent patients since 2012 [3]...

INTRODUCTION: Chronic kidney disease (CKD) is associated with an increased risk of cardiovascular disease and mortality, which is thought to be caused by increased propensity towards vascular calcification (VC). Magnesium (Mg) inhibits phosphate-induced VC in vitro and in animal models and serum Mg is inversely associated with cardiovascular mortality in predialysis CKD and in end-stage renal disease. This paper will describe the design and rationale of a randomised double-blinded placebo-controlled multicentre clinical trial, which will investigate whether oral Mg supplementation can prevent the progression of coronary artery calcification (CAC) in subjects with predialysis CKD...

Diabetic nephropathy (DN) is one of the most common and lethal microvascular complications of diabetes. This study aimed to explore whether coenzymeQ10 (CoQ10) as an antioxidant combined with ultrasound-targeted microbubble destruction (UTMD) could reverse the progress of early diabetic nephropathy (DN). CoQ10 has great potential to treat early DN. However, the clinical application of CoQ10 has been limited because of its low aqueous solubility and non-specific distribution. Therefore, CoQ10-loaded liposomes (CoQ10-lip) were prepared and combined with ultrasound microbubbles for the early theranostics of DN...

Ashish Francis, Richard Baynosa
Ischaemia-induced tissue injury has wide-ranging clinical implications including myocardial infarction, stroke, compartment syndrome, ischaemic renal failure and replantation and revascularization. However, the restoration of blood flow produces a 'second hit' phenomenon, the effect of which is greater than the initial ischaemic event and characterizes ischaemia-reperfusion (IR) injury. Some examples of potential settings of IR injury include: following thrombolytic therapy for stroke, invasive cardiovascular procedures, solid organ transplantation, and major trauma resuscitation...

AIM: Sphingosine-1-phosphate (S1P) influences resistance vessel function and is implicated in renal pathological processes. Previous studies revealed that S1P evoked potent vasoconstriction of the preglomerular microvasculature, but the underlying mechanisms remain incompletely defined. We postulated that S1P-mediated preglomerular microvascular vasoconstriction involves activation of voltage-dependent L-type calcium channels (L-VDCC) and the rho/rho kinase pathway. METHODS: Afferent arteriolar reactivity was assessed in vitro using the blood-perfused rat juxtamedullary nephron preparation and diameter was measured during exposure to physiological and pharmacological agents...

Preeclampsia is a complication affecting pregnant women worldwide, which leads to maternal and fetal morbidity and mortality. In this study, we evaluated the efficacy of ferulic acid (FA) on an N(ω) -nitro-L-arginine methyl ester hydrochloride (L-NAME) induced rat model of preeclampsia. L-NAME was administered to pregnant rats to induce preeclampsia. 48 rats were divided into three experimental groups (n=16 each): control group, preeclampsia group and preeclampsia with FA treatment (preeclampsia+FA). Physiological characteristics such as urine volume, total urine protein and blood pressure were assessed...

Plant flavonoids are well known as antioxidants against oxidative stress induced by exposure to external pollutants. Nicotine (NIC) is one of those agents which increases renal oxidative stress, an important factor in the pathogenesis of renal epithelial injury in smokers. Although several studies had been conducted on flavonoids and oxidative stress, the mechanism of the protective pathways are not fully understood. Here, we present studies on antioxidant properties of two mono-hydroxyflavone isomers, 3-hydroxyflanove (3HF)- and 7-hydroxyflavone (7HF), against nicotine-associated oxidative stress and injury in cultured renal proximal tubule cells and correlate their antioxidant properties with their chemical structure...

The SCHEDULE trial was a 12-month, randomized, open-label, parallel-group trial that compared everolimus (EVR; n=56) to conventional CsA (n=59) immunosuppression. Previously, we reported that EVR outperformed CsA in improving renal function and coronary artery vasculopathy, despite a higher rejection rate with EVR. The present study aimed to compare the effects of these treatments on quality of life (QoL). Within 5 postoperative days, patients (mean age 50±13 years, 27% women) were randomized to EVR or a standard CsA dosage (CsA group)...

The incidence of hip fracture in patients with end-stage renal disease (ESRD) is considerably higher than that in the general age- and sex-matched population. Although medical therapy for chronic kidney disease mineral bone disorder (CKD-MBD) has changed considerably over the last decade, rates of hip fracture in the entire ESRD population have not been well-characterized. Herein, we evaluated temporal trends in rates of hip fracture, in-hospital mortality, and costs of associated hospital stay in ESRD. We identified hospitalizations for hip fracture from 2003 to 2011 using the Nationwide Inpatient Sample, a representative national database inclusive of all ages and payers...
