New research in the Journal of Cell Biology helps explain how the toxic protein responsible for botulism can enter circulation from the digestive system. The study appears online May 10. Botulism, a rare but serious paralytic illness, is caused by botulinum neurotoxin (BoNT), an extremely toxic protein that is produced by the bacterium Clostridium botulinum. In food-borne botulism, the nontoxic components of BoNT"”including hemagglutinin (HA)"”protect the toxin from the low pH and...

Today, during the 39th Annual Meeting of the American Association for Dental Research, convening at the Walter E. Washington Convention Center in Washington, DC, lead researcher M. Tong, The Ohio State University, will present a poster of a study titled "Epithelial-to-Endothelial Transition: An Epithelial Phenotypic Modulation Facilitating Oral-Squamous-Cell Carcinoma Progression." Tong and a team of researchers have reported that oral squamous cell carcinoma (OSCC) cells endogenously produce...

Barrett's epithelium is recognized as a complication of erosive esophagitis and is the pre-malignant condition for adenocarcinoma of the esophagus. A research team from Yokohama City University School of Medicine hypothesized that some macroscopic features of Barrett's epithelium might be useful for identifying a subgroup with a high risk for the development of esophageal adenocarcinoma. Their study will be published on January 28, 2010 in the World Journal of Gastroenterology. They enrolled...

Scientists in Belgium have successfully differentiated human embryonic stem cells (hESC) into major cell types of lung epithelial tissue using a convenient air-liquid interface. The technique, published in BioMed Central's open access journal Respiratory Research, could provide an alternative to lung transplants for patients with lung injury due to chronic pulmonary disease and inherited genetic diseases such as cystic fibrosis. Lindsey Van Haute and colleagues from the Department of...

Researchers at the University of Pennsylvania School of Medicine have identified a master switch that might prevent cancer cells from metastasizing from a primary tumor to other organs. The switch is a protein that, when in the "on" position, maintains the normal character of cells that line the surface of organs and body cavities. These epithelial cells are the type of cell from which most solid tumors arise. However, when the switch is turned "off" or absent, epithelial cells acquire...

By Rickard, Alice Dorokhov, Nikolay; Ryerse, Jan; Klumpp, David J; McHowat, Jane Abstract Tight junctions (TJs) are essential for normal function of epithelia, restricting paracellular diffusion and contributing to the maintenance of cell surface polarity. Superficial cells of the urothelium develop TJs, the basis for the paracellular permeability barrier of the bladder against diffusion of urinary solutes. Focusing on the superficial cell layer of stratified cell cultures of an...

By Halldorsson, Skarphedinn Asgrimsson, Valthor; Axelsson, Ivar; Gudmundsson, Gudmundur Hrafn; Steinarsdottir, Margret; Baldursson, Olafur; Gudjonsson, Thorarinn Abstract Due to the cellular complexity of the airway epithelium, it is important to carefully define bronchial cell lines that capture the phenotypic traits of a particular cell type. We describe the characterization of a human bronchial epithelial cell line, VA10. It was established by transfection of primary bronchial epithelial...

BETHESDA, Md. (Oct. 3, 2005) "“ Multi-vitamin products, nutritional supplements and parents tout the need for such mineral elements as calcium, zinc, phosphorus, iron and others. Iron, for example, is a nutritional prerequisite to power life itself. When blood doesn't get enough iron from the gut, we become anemic. One of the body's coping mechanisms is to produce more of a protein called divalent metal transporter 1 (DMT1) in the gastrointestinal lining cells to bring into the body as...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
