This study demonstrates the effects of simulated microgravity on E. coli K 12 MG1655 grown on LB medium supplemented with glycerol. Global gene expression analysis indicated that the expressions of hundred genes were significantly altered in simulated microgravity conditions compared to that of normal gravity conditions. Under these conditions genes coding for adaptation to stress are up regula...

In this paper we propose an innovation model for the collaborationbetween SME and public research institutions in order to enhance knowledgetransfer and to foster the creation of a regional innovation network. A third aspectis to enhance a more intense cooperation in the public research sector betweeninstitutions and departments. In this paper we discuss the term innovation and<...

It is important to analyze the role of screens – computers specially – in the image era we are living, the development of computers as new characters in our every day lives and the intimate relationship established between the user and the multimedia background in front of him. E-mail, internet, animation programs, image processing and other social-artistic advantages of the computer bring othe...

Groman, Neal B. (University of Washington, Seattle). Factors in lysis and lysis inhibition by lambda bacteriophage. J. Bacteriol. 90:1563-1568. 1965.-Induced Escherichia coli strain K-12(lambda112) exhibited lysis inhibition at 37 C but lysed at 44 C when incubated in LB medium lacking NaCl [LB - (NaCl)]. In LB medium containing NaCl, the temperatures for lysis and lysis inhibition were reverse...

Two new human myeloma cell lines have been established from a 36-year-old woman with refractory IgG kappa multiple myeloma in whom bilateral malignant pleural effusions developed. The malignant plasma cells from each effusion were set up in a liquid culture using an L-15 medium containing catalase, glutathione, selenous acid, ascorbic acid, insulin, transferrin, additional glutamine hydrocortis...

ABSTRACT: Acidophilus milk after preparation, with the defined characteristics of pH, titratable acidity and viable counts of Lb. acidophilus, was kept at the refrigerator (5 °C) and changes of above mentioned parameters were evaluated during 21 days at 7-day intervals. The obtained results showed that the titratable acidity of product significantly (p≤0.05) increased over storage period, demon...

ion Level. Our solution combines imperative code in Java and declarative scripts in ETL andEGL. As a result, according to the evaluation criteria [2], the abstraction level of (a) the Java code to launchtransformations is low, (b) XML to XML-model transformation is low, (c) XML-model to Object-modeltransformation is high, (d) Object-model to code transformation is high, and (e) the ...

Vibrio parahaemolyticus harbours two distinct type III secretion systems (T3SS1 and T3SS2). A subset of 10 T3SS1 genes are transcribed when V. parahaemolyticus is grown in tissue culture medium [Dulbecco's modified Eagle's medium (DMEM)], while transcription of these genes (except exsD) is minimal upon growth in Luria-Bertani-Salt (LB-S). Transcription of T3SS1 genes and cytotoxicity towards He...

yqxM is a Bacillus subtilis gene of unknown function residing in an operon with sipW, which encodes a signal peptidase, and tasA, which encodes an antibiotic protein secreted in a sipW-dependent manner. YqxM was undetectable during growth in a variety of rich media, including Luria-Bertani (LB) medium, or in minimal media or under heat shock or ethanol stress conditions but was synthesized and ...

Inactivation of transcription factor sigma54, encoded by rpoN (glnF), restores high-temperature growth in Luria-Bertani (LB) medium to strains containing the heat-sensitive cell division mutation ftsZ84. Mutational defects in three other genes involved in general nitrogen control (glnD, glnG, and glnL) also suppress lethal filamentation. Since addition of glutamine to LB medium fully blocks sup...
