BACKGROUND & AIMS The ability to obtain unlimited numbers of human hepatocytes would improve the development of cell-based therapies for liver diseases, facilitate the study of liver biology, and improve the early stages of drug discovery. Embryonic stem cells are pluripotent, potentially can differentiate into any cell type, and therefore could be(More)
ABSTRACT To investigate the interaction between two major ear-rotting pathogens, maize ears were inoculated with either Fusarium graminearum, F. moniliforme, or an equal mixture of the two. Silk and kernel tissues were periodically harvested throughout the growing season so that a time course of the experimental variables (disease severity, ergosterol(More)
The signal recognition particle (SRP) consists of one RNA and six protein subunits. The N-terminal domain of the 54K subunit contains a putative GTP-binding site, whereas the C-terminal domain binds signal sequences and SRP RNA. Binding of SRP to the signal sequence as it emerges from the ribosome creates a cytosolic targeting complex containing the nascent(More)
Deoxynivalenol (DON) is a mycotoxin frequently found as a contaminant of cereal crops and may be etiologically associated with adverse health effects in developing countries where considerable quantities of contaminated crops are consumed. We investigated the metabolism of DON in rats as a basis to establish methodology for a candidate biomarker of human(More)
The mechanism of protein translocation across the endoplasmic reticulum membrane of eukaryotic cells and the plasma membrane of prokaryotic cells are thought to be evolutionarily related. Protein targeting to the eukaryotic translocation apparatus is mediated by the signal recognition particle (SRP), a cytosolic ribonucleoprotein, and the SRP receptor, an(More)
Consumption of corn or corn-based products contaminated with Fusarium moniliforme/fumonisins has been associated with a variety of animal and human diseases and is a major food/feed safety issue. This study focused on the clinical toxicity and performance parameters in growing swing exposed to low to moderate levels of pure fumonisin B1 (FB.) for 8 weeks.(More)
BACKGROUND Bronchial thermoplasty is a bronchoscopic procedure to reduce the mass of airway smooth muscle and attenuate bronchoconstriction. We examined the effect of bronchial thermoplasty on the control of moderate or severe persistent asthma. METHODS We randomly assigned 112 subjects who had been treated with inhaled corticosteroids and long-acting(More)
BACKGROUND/AIM A gastric conduit is usually used to reconstruct the foregut after esophagectomy for cancer. The gastric emptying may be impaired after this operation, so some esophageal surgeons routinely add a pyloric drainage procedure (pyloroplasty or pyloromyotomy). We performed a meta-analysis of randomized controlled trials (RCTs) to determine the(More)
This report concerns the development of a method for the measurement of ergosterol in indoor air as a determinant of fungal exposure. Ergosterol was determined in spores of 11 species of Aspergillus, Penicillium, and Cladosporium selected from the most common molds in 400 homes in Ontario. Spore ergosterol content was about 1 microgram/mg, which is the(More)
We delivered controlled radio frequency energy to the airways of anesthetized, ventilated dogs to examine the effect of this treatment on reducing airway narrowing caused by a known airway constrictor. The airways of 11 dogs were treated with a specially designed bronchial catheter in three of four lung regions. Treatments in each of the three treated lung(More)
