The potential risk of exposure to fumonisin B(2) (FB(2)) in the grape-wine chain has recently been revealed after a report of Aspergillus niger in grapes and its ability to produce FB(2) and FB(4). The occurrence of these two fumonisins in wine was investigated by LC/MS/MS in 51 market samples (45 red, five white and one rose wine) produced in various Italian regions. Nine samples of red wine w...

The streaming potential and the colloid particle deposition (referred to as colloid enhancement CE) methods were applied to characterize fibrinogen (Fb) monolayers on mica, produced by controlled adsorption under diffusion transport. The surface concentration of Fb was determined directly by AFM enumeration of single molecules adsorbed over the substrate surface. It was proven that Fb adsorbed ...

Fibrinolytic therapy may be effective in the treatment of ischemic stroke, and clinical trials are under way. We evaluated two fibrinolytic agents, an analogue of tissue plasminogen activator (Fb-Fb-CF, the catalytic fragment of the tissue plasminogen activator molecule with a prolonged serum half-life, n = 10) and streptokinase (n = 7), in a rabbit model of embolic stroke. Both agents were giv...

the field of cognitive psychology has increasingly provided scientific insights to explore how humans are subject to unconscious sources of evidentiary bias, leading to errors that can affect judgement and decision-making. increasingly these insights are being applied outside the realm of individual decision-making to the collective arena of policy-making as well. a recent editorial in this jou...

Foreign body (FB) ingestion is a relatively common reason for visits to the emergency room. If the FB is symptomatic or damaging to the patient, either endoscopic or surgical intervention should ensue. We present a case of abdominal pain and hematuria beginning ∼24 h after an incidental FB ingestion. Initial CT imaging defined a linear opacity perforating through the posterior duodenal wall abu...

TE146 is a giant transposon of Drosophila melanogaster. It carries two copies of the white and roughest genes, normally found on the X chromosome. The structure of this transposon has been studied at the molecular level. TE146 may transpose to new chromosome positions, excise and be lost from the genome or undergo internal rearrangements. The termini of TE146 are foldback DNA elements (FB); the...

BACKGROUND Lung radiation injury is a critical complication of radiotherapy (RT) for thoracic esophageal carcinoma (EC). Therefore, the goal of this study was to investigate the feasibility and dosimetric effects of reducing the lung tissue irradiation dose during RT for thoracic EC by applying volumetric modulated arc radiotherapy (VMAT) combined with active breathing control (ABC) for moderat...

Cortical inhibition is determined in part by the organization of synaptic inputs to gamma-aminobutyric acidergic (GABAergic) neurons. In adult rat visual cortex, feedforward (FF) and feedback (FB) connections that link lower with higher areas provide approximately 10% of inputs to parvalbumin (PV)-expressing GABAergic neurons and approximately 90% to non-GABAergic cells (Gonchar and Burkhalter ...

The effects of transplantation of fibroblasts genetically modified to produce brain derived neurotrophin factor (Fb/BDNF) on rescue of axotomized neurons, axonal growth and recovery of function was tested in a lateral funiculus lesion model in adult rats. Operated control animals included those in which the lesion was filled with gelfoam implant (Hx) and those in which the cavity was filled wit...

The value of 121 flexible bronchoscopy (FB) procedures was evaluated in 54 children, aged three months to 14 years, suspected of having pulmonary tuberculosis. Specimens from FB were culture-positive for Mycobacterium tuberculosis in seven of the 13 bacteriologically confirmed cases. Bronchial abnormalities consistent with the diagnosis were found in 31 of 54 cases. Separate or coexistent findi...
