Bioluminescence imaging (BLI) is a relatively new noninvasive technology used for quantitative assessment of tumor growth and therapeutic effect in living animal models. BLI involves the generation of light by luciferase-expressing cells following administration of the substrate luciferin in the presence of oxygen and ATP. In the present study, the effects of hypoxia, hypoperfusion, and pH on B...

In this paper we present a new method for the production of bubble-liquid suspensions ~from now on BLS! composed of micron-sized bubbles and with gas to liquid volume ratios larger than unity. We show that the BLS gas fraction l5Qg /Ql , being Qg and Ql the flow rates of gas and liquid, respectively, is controlled by a dimensionless parameter which accounts for the ratio of the gas pressure ins...

brucellosis is a well-known infection in domestic animals which caused by brucella bacterium. due toserious economic and medical consequences of this disease, various efforts have been made to prevent theinfection through the use of recombinant vaccines based on brucella outer membrane protein (omp)antigens. the objectives of the present study were cloning, sequencing and epitope prediction of ...

BACKGROUND Early recognition and immediate bystander cardiopulmonary resuscitation are critical determinants of survival after out-of-hospital cardiac arrest (OHCA). Our aim was to evaluate current knowledge on basic life support (BLS) in Danish high school students and benefits of a single training session run by junior doctors. METHODS Six-hundred-fifty-one students were included. They unde...

Ruminants are the primary reservoir of Shiga-toxin producing Escherichia coli (STEC) O157:H7 and the main source of infection for humans. The aim of this study was to assess the immunogenic properties of a candidate vaccine consisting on the recombinant proteins of E. coli O157:H7 IntiminC280, the carboxy-terminal fraction of Intimin γ, EspB and the fusion protein between the B subunit of Stx2 ...

Natural and anthropogenic release of metals into surface waters and sediments may alter benthic community structure. To better understand macroinvertebrate communities in metal-impacted shale-draining streams in north-central Arkansas, sediment and macroinvertebrate samples were collected from sites on black shale-draining (BLS) and limestone-draining streams (LMS; used as a reference stream). ...

Lactic acid bacteria (LAB) were isolated from ovine milk and cheeses manufactured in the South Region of Brazil. Among 112 bacterial isolates investigated, 59 were chosen through a screening for LAB. Among these 59 strains of LAB, 21% showed antimicrobial, proteolytic and lipolytic activities. Based on this screening, Lactobacillus plantarum LCN 17 and Lactobacillus rhamnosus LCN 43 were select...
