RATIONALE: Intrinsic biogeochemical markers, such as stable isotope ratios of carbon, nitrogen and sulphur are increasingly used to trace the trophic ecology of marine top predators. However, insufficient knowledge of fractionation processes in tissues continues to hamper the use of these markers. METHODS: We performed a controlled feeding experiment with eight juvenile hooded seals (Cystophora cristata) that were held on a herring-based diet (Clupea harengus) for two years...

BACKGROUND: Anastomotic stricture is the most common postoperative complication in infants undergoing repair of esophageal atresia with or without tracheoesophageal fistula (EA/TEF). Stricture indices (SIs) are used to predict infants at risk for stricture requiring dilation. We sought to determine the most accurate SI and optimal timing for predicting anastomotic dilation. MATERIALS AND METHODS: A retrospective study of infants undergoing repair of EA/TEF between 2008 and 2013 was performed...

Interkinetic nuclear migration (INM) is a cell polarity-based phenomenon in which progenitor cell nuclei migrate along the apico-basal axis of the pseudostratified epithelium in synchrony with the cell cycle. INM is suggested to be at least partially cytoskeleton-dependent and to regulate not only the proliferation/differentiation of stem/progenitor cells but also the localized/overall size and shape of organs/tissues. INM occurs in all three of the germ-layer derived epithelia, including the endoderm-derived gut...

PURPOSE: Congenital esophageal atresia (CES) is a rare congenital disease. The severity of symptoms is variable; thus, diagnosis is difficult and tends to be delayed. CES is frequently accompanied by esophageal atresia (EA) with/without tracheoesophageal fistula (TEF). We investigated the characteristics of CES by reviewing our experience with CES patients and researched the differences between CES with EA-TEF and isolated CES. METHODS: A total of 31 patients underwent operations for CES were reviewed retrospectively...

Triethoxyfluorosilane (TEFS), which is a pendant-type alkoxysilane with a Si-F bond, was utilized for the development of a molecular sieving membrane. The effect that a source of fluorine and calcination temperature exerted on gas permeation properties and network pore size was evaluated via single-gas permeation properties across a wide range of temperatures. A TEFS membrane calcined at 350 °C showed high H2 permeance (2.0 × 10(-6) mol m(-2) s(-1) Pa(-1)) and high selectivity for H2 over larger molecules (H2/CF4: >300; H2/SF6: >18 000), indicating that this network pore size would be suitable for a H2 permselective membrane that could promote the process of methylcyclohexane (MCH) dehydrogenation to produce toluene (TOL)...

In vitro reporter gene assays detecting dioxin-like compounds have been developed and validated since the middle 1990's, and applied to the determination of dioxin-like activities in various samples for their risk management. Data on characterizing the potency of individual brominated dioxins and their activity in mixture with chlorinated dioxins are still limited on the cell-based assay. This study characterized the dioxin-like activities of the 32 brominated dioxins, such as polybrominated dibenzo-p-dioxins, polybrominated dibenzofurans (PBDFs), coplanar polybrominated biphenyls, mixed halogenated dibenzo-p-dioxins and dibenzofurans (PXDFs), as a sole component or in a mixture by DR-CALUX (dioxin-responsive chemically activated luciferase expression) using the rat hepatoma H4IIE cell line and XDS-CALUX (xenobiotic detection systems-chemically activated luciferase expression) assays using the mouse hepatoma H1L6...

Studying community structure and dynamics of plant-associated fungi is the basis for unravelling their interactions with hosts and ecosystem functions. A recent sampling revealed that only a few fungal groups, as defined by internal transcribed spacer region (ITS) sequence similarity, dominate culturable root endophytic communities of nonmycorrhizal Microthlaspi spp. plants across Europe. Strains of these fungi display a broad phenotypic and functional diversity, which suggests a genetic variability masked by ITS clustering into operational taxonomic units (OTUs)...

BACKGROUND: Transanastomotic feeding tube (TAFT) is commonly used for post-operative enteral nutrition after esophageal atresia (EA)/tracheoesophageal fistula (TEF) repairs. The purpose of this study is to analyze the therapeutic implications of avoiding a TAFT and its impact on the outcomes post-operatively. METHODS: The medical data of 33 inpatients with EA/TEF type C repair from 2009 to 2014 was retrospectively reviewed. Patients were divided into two groups for comparison based on the usage of TAFT during the repair: TAFT- (without) and TAFT+ (with) groups, without randomization...

Fusarium proliferatum is a world-wide occurring fungal pathogen affecting several crops included garlic bulbs. In Spain, this is the most frequent pathogenic fungus associated with garlic rot during storage. Moreover, F. proliferatum is an important mycotoxigenic species, producing a broad range of toxins, which may pose a risk for food safety. The aim of this study is to assess the intraspecific variability of the garlic pathogen in Spain implied by analyses of translation elongation factor (tef-1α) and FUM1 gene sequences as well as the differences in growth rates...

A central step to elucidate the function of proteins commonly comprises the analysis of their molecular interactions in vivo. For nuclear regulatory proteins this involves determining protein-protein interactions as well as mapping of chromatin binding sites. Here, we present two protocols to identify protein-protein and chromatin interactions of transcript elongation factors (TEFs) in Arabidopsis. The first protocol (Subheading 3.1) describes protein affinity-purification coupled to mass spectrometry (AP-MS) that utilizes suspension cultured cells as experimental system...

Understanding spatio-temporal variability of trace elements fingerprints (TEF) in bivalve shells is paramount to determine the discrimination power of this analytical approach and secure traceability along supply chains. Spatio-temporal variability of TEF was assessed in cockle (Cerastoderma edule) shells using inductively coupled plasma-mass spectrometry (ICP-MS). Four elemental ratios (Mg/Ca, Mn/Ca, Sr/Ca and Ba/Ca) were measured from the shells of specimens originating from eight different ecosystems along the Portuguese coast, as well as from four different areas, within one of them, over two consecutive years (2013 and 2014)...

PURPOSE: Perioperative management of infants with esophageal atresia and tracheoesophageal fistula (EA/TEF) is frequently based on surgeon experience and dogma rather than evidence-based guidelines. This study examines whether commonly perceived important aspects of practice affect outcome in a contemporary multi-institutional cohort of patients undergoing primary repair for the most common type of esophageal atresia anomaly, proximal EA with distal TEF. METHODS: The Midwest Pediatric Surgery Consortium conducted a multicenter, retrospective study examining selected outcomes on infants diagnosed with proximal EA with distal TEF who underwent primary repair over a 5-year period (2009-2014), with a minimum 1-year follow up, across 11 centers...

OBJECTIVE: Recurrent tracheoesophageal fistula (TEF) can be a diagnostic and therapeutic challenge. Traditional treatment is thoracotomy, which carries significant morbidity and technical difficulty especially in a previously operated field. Recently, endoscopic techniques have been advocated as a primary approach for treatment of recurrent TEF prior to open repair. This case report describes the endoscopic technique used to address a recurrent TEF. The existing literature of all reported endoscopic cauterization methods is reviewed...

A risk assessment was performed of parsley and dill based plant food supplements (PFS) containing apiol and related alkenylbenzenes. First the levels of the alkenylbenzenes in the PFS and the resulting estimated daily intake (EDI) resulting from use of the PFS were quantified. Since most PFS appeared to contain more than one alkenylbenzene a combined risk assessment was performed based on equal potency or using a so-called Toxic Equivalency (TEQ) approach based on Toxic Equivalency Factors (TEFs) for the different alkenylbenzenes...
