High pressure processing (HPP) is becoming of increasing importance in the food industry as it offers the opportunity to obtain minimally processed food products with increased safety and extended shelf-life. A sound knowledge of the effects of high pressure on meat attributes is necessary for a successful implementation of HPP in the meat industry. The aim of this work was to determine the eff...

MAX 250 WORDS) 14 Dissemination of Shiga toxin-encoding bacteriophages by transduction is the most 15 likely mechanisms for the spread of Stx-encoding genes and the emergence of new Shiga 16 toxin-producing Escherichia coli (STEC). Biofilm have been reported to be a place where 17 horizontal gene transfer by plasmid conjugation and DNA transformation may occur, and in 18 this study horizontal g...

Using 2-dimensional electrophoresis based proteomics we have investigated the protein expression profile of bovine M. longissimus thoracis et lumborum at day 2 (n=3) and day 14 (n=3) in tenderstretched and conventionally hung carcasses. From 1248 protein features detected by image analysis, 191 manually curated spots were subjected to statistical analysis. From this initial analysis, at day 2 p...

We evaluated serum and urine sodium levels in children with dengue infections. Children with acute febrile illness admitted to Bhumibol Adulyadej Hospital in Bangkok from January 1999 to January 2000 were enrolled. Serum and urine sodium levels were measured before initiating intravenous fluid therapy. Two milliliters of blood were obtained on admission and before discharge to test for anti-den...

Numerous lines of evidencel'indicate that protein synthesis occurs within mitochondria, and tRNA8, 15, 16 and aminoacyl-RNA synthetases8 have been prepared from these organelles. More recently, two very interesting aspects of mitochondrial protein synthesis have been described: (a) Although amino acid incorporation by yeast cytoplasmic ribosomal systems is not inhibited by chloramphenicol,'7 pr...

Dear Editor, Nasal polyp is a common chronic inflammatory disease of the sinonasal mucosa that is histologically characterized by infiltration of eosinophils and large quantities of extracellular edema. It causes considerable morbidity such as nasal obstruction, rhinorrhea and sleep disorders. Pathogenesis of nasal polyps is still debatable. Helicobacter pylori may play a role in the pathogenes...

Most cases of anaphylaxis caused by ants are attributed to ants from the Solenopsis genus [1] but there are many ant species of different genera and their distribution around the world varies. In Brazil, where there are over 2000 catalogued species of ants, all the cases of ant-induced anaphylaxis reported to date have been attributed to Solenopsis species [2,3]. We describe the fi rst case of ...

This study was conducted to investigate the influence of the saturating cation on the adsorption of parathion, methyl parathion, fenitrothion, aminoparathion, and paraoxon by montmorillonite suspensions. In all cases the saturating cation distinctly influenced the Freundlich-type adsorption, with adsorption decreasing in the following sequence: Fe—> Ca— > Na-montmorillonite. Adsorption of parat...

INTRODUCTION. Human cartilage glycoprotein 39 (HC gp-39), a member of the mammalian protein family related in sequence to the bacterial chitinases, has been reported as a major secretory glycoprotein of cultured human articular chondrocytes and synovial fibroblasts [1]. Although HC gp39 was undetectable in normal cartilage by Northern and Western blot analyses, it was reported to be highly expr...
