This study aimed to examine the rate of symptomatic improvement of congenital nasolacrimal duct obstruction (CNLDO) in Japanese infants treated with conservative management within the 1st year of age. Thirty-five lacrimal ducts in 27 patients diagnosed with CNLDO were included in the study. During the observational period, lacrimal ducts were massaged. As well, antibiotic eye drops, to be admin...

The purpose of this study was to compare histologic subtype and growth pattern, including invasion and intraductal spread to branch ducts, in main duct-type intraductal papillary-mucinous carcinoma (IPMC) by histopathology and immunohistochemistry. Five surgically resected samples of main duct-type IPMC from five patients, were studied. Main lesions, invasive components, and adjacent secondary ...

We investigated the distribution of endothelin A (ET(A)) receptor-like immunoreactivity in the rat kidney using affinity-purified antibodies against amino acid residues 403-417 of the rat ET(A) receptor modified by the multiple antigen peptide complex system. Western blot analysis using the affinity-purified anti-ET(A) antibody detected bands of approximately 47.3 and 64.5 kDa in the rat kidney...

Abstract This paper presents the numerical study of thermal performance factor Al 2 O 3 -Cu/water hybrid nanofluid in circular and non-circular ducts (square rectangular). Turbulent regime is studied with Reynolds number ranges from 10000 to 100000. The heat transfer flow behaviour are investigated, considering volume concentration between 0.1 2%. evaluated terms evaluation criteria (PEC). pres...

We show that the one-dimensional (1D) two-fluid model (TFM) for stratified flow in channels and pipes (in its incompressible, isothermal form) satisfies an energy conservation equation, which arises naturally from mass momentum equations constitute model. This result extends upon earlier work on shallow water (SWE), with important difference we include non-conservative pressure terms analysis, ...

Sound reduction is complex to estimate for acoustical treatments on ventilation ducts through walls. Various are available ducts, including internal lining (absorption along the inner perimeter), external lagging (external sound insulation), silencer, and suspended ceilings. Previous studies have examined how silencers affect transmission of ducts. However, there few theories predict effect in ...

The paper presents noise reduction (NR) of spiral ducts as a result of computational modeling of acoustic wave propagation. Three-dimensional models were created with the finite element method in COMSOL Multiphysics version 3.3. Nine models of spiral ducts with 1-9 spiral leads were considered. Time-harmonic analysis was used to predict NR, which was shown in spectral and interval frequency ban...

To study the impairment of cholangiocyte primary cilia caused by prolonged cold preservation and its correlation with graft cholangiopathy after orthotopic liver transplantation (OLT). Subjects were 60 male Wistar rats that were divided into 2 groups: a control group (n = 30) receiving a donor liver preserved for 1 h and a study group (n = 30) receiving a donor liver preserved for 12 h. A two-c...

Pancreaticobiliary maljunction (PBM) is a congenital anomaly defined as junction of the pancreatic and bile ducts located outside the duodenal wall beyond the influence of the sphincter of Oddi, usually forming a markedly long common channel. Other names are “anomalous arrangement of pancreaticobiliary ducts” or “anomalous union of biliopancreatic ducts” [1]. Average length of common channel is...

PURPOSE In a pilot study of women with pathologic nipple discharge (PND) undergoing ductoscopy, we tested quantitative assessment of gene promoter hypermethylation using quantitative multiplex methylation-specific PCR (QM-MSP) to enhance detection of duct carcinoma in situ (DCIS). EXPERIMENTAL DESIGN Women with PND underwent ductoscopy; ducts with significant lesions were surgically resected ...
