In this report, conditioned media from LPS-stimulated monocytes increased rat hepatocyte production of fibronectin (Fn) in a dose-dependent manner. Preincubation of the conditioned media with anti-IL-6, but not with anti-IL-1 alpha, anti-IL-1 beta, or anti-TNF, completely neutralized the Fn-stimulating activity. 10-100 pg/ml of rIL-6 was sufficient to increase Fn production. Neither IL-1 nor TN...

Demain, A. L. (Merck Sharp & Dohme Research Laboratories, Rahway, N.J.), Joanne F. Newkirk, and D. Hendlin. Effect of methionine, norleucine, and lysine derivatives on cephalosporin C formation in chemically defined media. J. Bacteriol. 85: 339-344. 1963.-Chemically defined media were developed for production of cephalosporin C by Cephalosporium sp. In such media, the requirement for methionine...

This article discusses the state of the art in metadata for audio-visual media in large semantic networks, such as the Semantic Web. Our discussion is predominantly motivated by the two most widely known approaches towards machine-processable and semantic-based content description, namely the Semantic Web activity of the W3C and ISO's efforts in the direction of complex media content modeling, ...

The present study is concerned with the production of cephalosporin C by Cephalosporium acremonium C-10. Two culture media were tested for the production of antibiotic. Among these culture media M1 containing sucrose, ammonium acetate, cornstarch, sugar cane molasses, soybean meal, calcium carbonate, calcium sulphate and methyl oleate gave optimum production of cephalosporin C. The cultural con...

The twenty years since the first digital video camera was made commercially available has seen significant increases in the use of low-cost, amateur video productions for teaching and learning. In the same period, production and consumption of professionally produced video has also increased, as has the distribution platforms to access it. Furthermore, advances in social media technologies and ...

many factors may influence the efficiency of somatic embryogenesis. this capability may be differ with regard to media compositions, genotype, tissue, organ ontology and the stage of differentiation. the effects of five salicylic acid concentrations (0, 25, 50, 75 and 100 mm) on different stages of carrot somatic embryogenesis were studied using petiole and root secondary phloem explants as sta...

chemical flooding, especially alkaline/surfactant/polymer flooding, is of increasing interest due to the world increasing oil demand. this work shows the aspects of using alkaline/surfactant/polymer as an enhanced oil recovery method in the porous media having a high dead-end pore frequency with various dead-end pore parameters (such as opening, depth, aspect ratio, and orientation). using glas...

background;it is important to know media and educational intervention and also produce them according to standards. thus, media and health educational interventions should evaluate to improve education quality. methods;the study sample were whole produced media and interventions in all medical universities, deportments, offices, and centers affiliated to ministry of health in 2008 and in the fi...

Social media plays an important role in the process of political engagement, especially in societies where significant constraints over traditional media and participation still exist. Little is known about how social media use is related to these constraints. This study examines how citizens’ perceptions of government control predict social media use and how this use is related to offline part...

We present a stochastic analysis of immiscible two-phase flow ~Buckley–Leverett displacement! in heterogeneous reservoirs. Since the detailed spatial variabilities of reservoir properties such as permeability and porosity cannot be described deterministically, both permeability and porosity, or either, are treated as random space functions. In turn, water saturation and oil production rate are ...
