AIM: This investigation explored the hypothesis that in obesity an inflammatory response in the kidney contributed to a renal nerve-dependent blunting of the baroreflex regulation of renal sympathetic nerve activity. METHODS: Rats received a normal (12%Kcal) or high-fat (45%Kcal) diet for 8 weeks plus daily injections of vehicle (0.9% NaCl i.p) or tacrolimus (0.25mg kg(-1) day(-1) i.p) from weeks 3-8. Following anaesthesia, left renal sympathetic nerve activity was recorded, baroreflex gain curves were generated, by infusing phenylephrine and sodium nitroprusside, and cardiopulmonary baroreceptors challenged by infusing a saline load...

BACKGROUND: The renoprotective effects of the direct renin inhibitor, aliskiren, in renal transplant recipients have been supposed, but not finally proven. We performed an exploratory double-blind, losartan controlled, cross-over study to evaluate the influence of aliskiren, direct renin inhibitor, on albuminuria and other surrogate markers of kidney injury in patients after renal transplantation. The safety of this therapy was also evaluated. METHOD: 16 of 18 patients (12 M, 4 F), 48...

The knowledge of metabolic profile of synthetic cannabinoids is important for the detection of drugs in urinalysis due to the typical absence or low abundance of parent cannabinoids in human urine. The fungus Cunninghamella elegans has been reported to be a useful tool for metabolism study and thus applicability to synthetic cannabinoid metabolism was examined. In this study, 8-quinolinyl 1-(5-fluoropentyl)-1H-indole-3-carboxylate (5F-PB-22), 8-quinolinyl 1-pentyl-1H-indole-3-carboxylate (PB-22), [1-(5-fluoropentyl)-1H-indol-3-yl](2,2,3,3-tetramethylcyclopropyl)methanone (XLR-11) and (1-pentyl-1H-indol-3-yl)(2,2,3,3-tetramethylcyclopropyl)methanone (UR-144) were incubated with C...

A 35-year-old woman presented to our institution with tender, right knee swelling. Radiological and pathological work-up revealed metastatic osteosarcoma. Prior to the initiation of chemotherapy, she underwent a routine urine pregnancy test and was surprised with a positive result. Serum beta human chorionic gonadotropin (βhCG) levels were also consistently positive and rising. No gestational sac was seen at transvaginal ultrasound. The paraneoplastic ectopic secretion of βhCG has been well described in gestational trophoblastic and gonadal tumours but has very rarely been associated with other tumour types...

Ethyl glucuronide (EtG) is an ethanol metabolite and EtG is used as a biomarker of alcohol drinking. EtG can be detected in the blood and in several biological matrices including urine, hair and nails. Alcohol consumption during pregnancy is a strong risk factor for fetus health so in the recent years different strategies to reveal alcohol use have been planning including the use of screening questionnaires as the AUDIT-C, T-ACE and TWEAK. The present study aims to investigate in pregnant women the specificity and predictive value of the AUDIT-C, T-ACE and TWEAK plus a food diary in use in Sapienza University Hospital compared with the results of urine EtG measurement...

Multiple myeloma (MM) is a clonal proliferation of malignant plasma cells in the bone marrow (BM) that secretes monoclonal paraproteins in the blood serum and urine. Bone marrow MM cells can invade and damage the functions of other tissues and organs, such as the lungs, spleen, liver, pancreas, kidneys and lymph nodes. However, the invasion of MM cells primarily located in the BM to the anterior mediastinum at the site of the thymus is an extremely rare event. The current study reports the case of a 53-year-old female who presented with MM with involvement of the anterior mediastinum...

A carcinoid tumor of the pancreas (CTP) is a rare pancreatic neoplasm, and usually presents with carcinoid syndrome (CS). CS consists of the classic symptom triad of cutaneous flushing, diarrhea and valvular disease, and occurs in the majority of patients with liver metastases. In the present study, the patient presented with symptoms of CS. A diagnosis of CTP with CS was suspected due to high levels of urine 5-hydroxyindolacetic acid, and this was confirmed by a fine-needle aspiration biopsy. Computed tomography showed extended lymphadenopathy, but no liver metastases...

Epilobium sp. are commonly used in traditional medicine in the treatment of early stages of benign prostatic hyperplasia and inflammation. It is suggested that a dominating constituent, oenothein B, is responsible for the extracts therapeutic effects. Several bioactivities were established for extracts and oenothein B in various in vitro models, but due to the questionable bioavailability of this dimeric macrocyclic ellagitannin, their significance in the in vivo effects remains unresolved. We have thus focused our attention on a complex comparative investigation of the in vitro and in vivo activities of phytochemically characterized Epilobium angustifolium aqueous extract and oenothein B on prostate cancer cells proliferation...

Pyrethroids are insecticides frequently used in agriculture and in the home; exposure occurs through dietary and non-dietary pathways, including indoor and outdoor environmental contamination. Our objective was to study the potential determinants of pyrethroid metabolite concentrations measured in children's urine samples and in the dust of their homes. Specifically, we measured urinary metabolites from morning spot samples of 245 six-year-old children living in Brittany (France) in 2009-2012 and from dust vacuumed from the floor of their homes...

Using a homemade auxiliary device, urinating in a standing position was a feasible alternative to a seated position for women during pregnancy. Pregnant women can experience difficulty voiding in a squatting or crouching position in the absence of a sitting toilet; voiding in a standing position represents a potential alternative. In previous studies [1, 2], voiding in the standing position using a homemade auxiliary device was demonstrated to be a feasible alternative for both young, healthy women [1] and elderly patients with knee osteoarthritis [2]...

There is a growing body of evidence demonstrating an association between smoking and DNA methylation. Accordingly, DNA methylation is now considered a promising biomarker of smoking exposure. We evaluated the relationship between methylation markers (AHRR and F2RL3) and urine cotinine as well as self-reported smoking status. DNA methylation levels of AHRR and F2RL3 in blood as well as urine cotinine were measured in 330 adults (46 to 87 years of age). Pyrosequencing was performed to measure DNA methylation of AHRR and F2RL3 associated with smoking exposure...

BACKGROUND: Type-D personality, defined as a combination of high negative affect and high social isolation, has been associated with poor health outcomes. However, pathways underlying this association are largely unknown. We investigated the relationship between Type-D personality and several biological and behavioral pathways including the autonomic nervous system, the immune system, glucose regulation and sleep in a large, apparently healthy sample. METHODS: Data from a total of 646 respondents (age 41...

For the 2014 World Cup and the 2016 Olympic Games, Brazil has expanded its airport infrastructure. This will lead to an increase in wastewater generation from aircrafts. This wastewater is traditionally taken from the aircrafts and disposed in the public sewage collection system. However, this residual water may have a different composition than the usual sanitary sewage. Therefore, it is important to study an alternative to treat this kind of wastewater. Thus, the objective of this study was to characterize and analyze the treatment of wastewater from airplane toilets through chemical precipitation for the removal of ammonia in the form of struvite...

This work presents and explores a novel methodology for the removal and recovery of ammonia from wastewater based upon two mechanisms: electrochemical oxidation and a previously unreported electrochemically-assisted surface transfer mechanism. Recovery of ammonia is enabled by placing a porous cathodic electrode at the wastewater-air interface. In this configuration, the cathode creates local alkalinity and an electric field that draws ammonium ions towards the wastewater-air interface, resulting in near-linear reductions of dissolved ammonium irrespective of concentration...
