Studying the Helminthological Collection of Museo de La Plata (MLP-He), several specimens of digeneans, recovered parasitizing a long-winged harrier, Circus buffoni (Accipitridae) from Buenos Aires Argentina, were analysed. The morphological and morphometric analysis of these specimens revealed the presence of two strigeid species, one of them new for science. Parastrigea buffoni n. sp. is characterised by a forebody differentiated in a retractile cephalic region with a large opening and a balloon-shaped collar region or collerette, suckers located in cephalic region, holdfast organ with well development dorsal and ventral lips that can emerge through opening, a claviform hindbody, a large copulatory bursa with muscular ring (Ringnapf) and a genital cone well delimited, crossed by a sinuous hermaphroditic duct with internal rugae...

BACKGROUND: Although some familial cancer syndromes include biliary tract cancers (BTCs) (cancers of the gallbladder, intrahepatic and extrahepatic bile ducts, and ampulla of Vater), the few studies that have examined the relationships between family history of cancer (FHC) and BTCs have reported inconclusive findings. The objective of this study was to investigate the associations of FHC with risk of BTC in the Biliary Tract Cancers Pooling Project (BiTCaPP). METHODS: We used Cox proportional hazards regressions models to estimate HRs and 95% confidence intervals for associations between FHC (any, 1st degree, in female relative, in male relative, relative with gastrointestinal cancer, and relative with hormonally-related cancer) and BTC risk by anatomic site within the biliary tract, adjusting for sex and race/ethnicity...

BACKGROUND: Exosomes are nanovesicles that have been shown to mediate carcinogenesis in pancreatic ductal adenocarcinoma (PDAC). Given the direct communication of pancreatic duct fluid with the tumor and its relative accessibility, we aimed to determine the feasibility of isolating and characterizing exosomes from pancreatic duct fluid. METHODS: Pancreatic duct fluid was collected from 26 patients with PDAC (n = 13), intraductal papillary mucinous neoplasm (IPMN) (n = 8) and other benign pancreatic diseases (n = 5) at resection...

It is known that bradykinin (BK) B2 receptor (B2R) is expressed in the collecting duct (CD) cells of the newborn rat kidney, but little is known about its role during early postnatal life. Therefore, we hypothesize that BK could participate in the mechanisms that mediate CD formation during the postnatal renal development. Performing primary cultures, combined with biochemical, immunocytochemical, and time-lapse analysis, we studied the role of BK in CD cell behaviour isolated from renal papilla of neonatal rats...

The incidence of gastric cancer (GC) is extremely high in East Asia. GC is also one of the most common and lethal forms of cancer from a global perspective. However, to date, we have not been able to determine one or several genes as biomarkers in the diagnosis of GC and have also been unable to identify the genes which are important in the therapy of GC. In this study, we analyzed all genome-wide expression profiling arrays uploaded onto the Gene Expression Omnibus (GEO) database to filtrate the differentially expressed genes (DEGs) between normal stomach tissues and GC tissues...

Caveolin-1 (Cav1) is essential for the formation of caveolae. Little is known about their functional role in the kidney. We tested the hypothesis that caveolae modulate renal salt and water reabsorption. Wild-type (WT) and Cav1-deficient (Cav1-/-) mice were studied. Cav1 expression and caveolae formation were present in vascular cells, late distal convoluted tubule and principal connecting tubule and collecting duct cells of WT but not Cav1-/- kidneys. Urinary sodium excretion was increased by 94% and urine flow by 126% in Cav1-/- mice (p < 0...

Renal medullary carcinomas (RMCs) and collecting duct carcinomas (CDCs) are rare subsets of lethal high-stage, high-grade distal nephron-related adenocarcinomas with a predilection for the renal medullary region. Recent findings have established an emerging group of fumarate hydratase (FH)-deficient tumors related to hereditary leiomyomatosis and renal cell carcinoma (HLRCC-RCCs) syndrome within this morphologic spectrum. Recently developed, reliable ancillary testing has enabled consistent separation between these tumor types...

Cholestasis is a disorder characterized by impaired bile flow and accumulation of cytotoxic bile acids in the liver. On the other hand, oxidative stress and its deleterious consequences seem to have a significant role in cholestasis-induced organ injury. Hence, antioxidants and thiol-reducing agents could have potential protective effect against this complication. The current investigation was designed to evaluate the effect of dithiothreitol (DTT) as a safe and clinically applicable thiol-reductant in cholestatic animals...

Therapeutic proteins can facilitate the targeting and treatment of lymphatic diseases (such as cancer metastases, infections and inflammatory diseases) since they are cleared via the lymphatics following interstitial (SC or IM) administration. However, therapeutic proteins are often administered intravenously (IV). Recently therapeutic proteins have been found to access the thoracic lymph in surprisingly high quantities after IV administration. The aim of this study was to determine, for the first time, the major sites of thoracic lymph access of therapeutic proteins, and the protein properties that enhance lymph access, after IV administration...

Pregnant women with type I diabetes mellitus (T1DM) are at increased risk of developing preeclampsia (PE). Plasminogen is aberrantly filtrated from plasma into tubular fluid in PE patients and activated to plasmin. Plasmin activates the epithelial sodium channel in the collecting ducts potentially causing impaired sodium excretion, suppression of the renin-angiotensin-aldosterone system, and hypertension in PE. The objective of the study was to test whether urinary total plasmin(ogen)/creatinine ratio and plasma concentration of aldosterone were better predictors of PE in pregnant women with T1DM compared with urine albumin and haemoglobin A1C...

The purpose of this study was to determine the time course for the previously reported reduction in sweat sodium ion concentration during heat acclimation. Four healthy volunteers completed 7 consecutive days of heat acclimation which included 2h of treadmill walking in a 40°C and 40% relative humidity environment. A modified constant hyperthermia protocol was used as workloads were increased each day to maintain a constant core temperature over the 7 days of heat acclimation. Forearm sweat was collected 3 times during each 2h exercise bout on days 1, 3, 5, and 7 of heat acclimation...

Pancreatic ductal adenocarcinoma (PDAC) continues to carry the lowest survival rates among all solid tumors. A marked resistance against available therapies, late clinical presentation and insufficient means for early diagnosis contribute to the dismal prognosis. Novel biomarkers are thus required to aid treatment decisions and improve patient outcomes. We describe here a multi-omics molecular platform that allows for the first time to simultaneously analyze miRNA and mRNA expression patterns from minimal amounts of biopsy material on a single microfluidic TaqMan Array card...

AIM: To explore the pharmacokinetics and pharmacodynamics of Shengjiang decoction (SJD) in rats with acute pancreatitis (AP) for protecting against multiple organ injury. METHODS: An AP model was established by retrograde perfusion of 3.5% sodium taurocholate into the biliopancreatic duct, and a control group (CG) received 0.9% sodium chloride instead. Twelve male Sprague-Dawley rats were randomly divided into a CG treated with SJD (CG + SJD) and a model group treated with SJD (MG + SJD), both of which were orally administered with SJD (5 g/kg) 2 h after surgery...

Type B and non-A, non-B intercalated cells are found within the connecting tubule and the cortical collecting duct. Of these cell types, type B intercalated cells are known to mediate Cl- absorption and HCO3- secretion largely through pendrin-dependent Cl-/HCO3- exchange. This exchange is stimulated by angiotensin II administration and is also stimulated in models of metabolic alkalosis, for instance after aldosterone or NaHCO3 administration. In some rodent models, pendrin-mediated HCO3- secretion modulates acid-base balance...

The authors present a case report of collecting duct carcinoma (CDC) that responded to nivolumab, a programmed death 1 (PD-1) immune-checkpoint-inhibitor antibody, following the failure of systemic treatment with chemotherapy and targeted therapy. The patient underwent right radical nephrectomy and segmentectomy of the lung following chemotherapy. Fifteen months following the first surgery, segmentectomy and subsequent second-line chemotherapy were performed for recurrence in the lung. Targeted therapy with temsirolimus for recurrence of the lung and lymph node metastases was ultimately used for 30 months...

OBJECTIVE: Antiangiogenic receptor tyrosine kinase inhibitors (RTKI) induce arterial hypertension which may limit their use. Renal fractional sodium excretion (FENa) is reduced in early RTKI-induced hypertension, whereas fractional lithium excretion is unaltered. Therefore, we tested the hypothesis that activated distal tubule and collecting duct sodium reabsorption contributes to RTKI-induced hypertension. METHODS: Amiloride-sensitive and hydrochlorothiazide (HCTZ)-sensitive fractional sodium reabsorption (FRNa) and renal epithelial sodium channel (ENaC) as well as sodium chloride cotransporter (NCC) abundances were determined in sunitinib-treated and control rats...
