We studied the effect of troglitazone on cellular acid-base balance and alanine formation in isolated rat mesangial cells. Mesangial cells were grown to confluency in RPMI 1640 media on 30mm chambers used to monitor both cellular pH using the pH-sensitive dye 2'7'-bis (2-carboxyethyl)-5,6carboxyfluorescein and metabolic acid production as well as glutamine metabolism. Troglitazone (10μM) induce...

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...

Drought stress in the field has been shown to exacerbate aflatoxin contamination of maize and peanut. Drought and heat stress also produce reactive oxygen species (ROS) in plant tissues. Given the potential correlation between ROS and exacerbated aflatoxin production under drought and heat stress, the objectives of this study were to examine the effects of hydrogen peroxide (H2O2)-induced oxida...

The goal of this research is to optimize PHA production in the syngas fermenting organism Rhodospirillum rubrum. Syngas fermentation is the hybrid thermochemical/ biological approach to processing biomass into valuable fuels and chemicals. The process begins with the gasification of biomass to produce syngas, a flammable gas mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), a...

Gas-liquid chromatography was used to monitor the evolution of short chain fatty acids by Bacteroides fragilis in five media. Acetic and succinic acids, the prominent end products encountered, were readily detected within 24 h. Propionic, isobutyric, isovaleric, and lactic acids were usually recorded in more limited quantities. Maximum rates of bacterial multiplication, glucose catabolism, and ...

Media professionals – such as news editors, image researchers, and documentary filmmakers increasingly rely on online access to digital content within audiovisual archives to create narratives. Retrieving audiovisual sources therefore requires an in-depth knowledge of how to find sources digitally. These storytelling practices intertwine search technologies with the user’s ideas and production ...

Microbial production of citric acid was performed by Yarrowia lipolytica NBRC 1658 and a domestic strain in the media containing glucose or fructose as substrates. The study was carried out in a batch system. The non-competitive substrate inhibition model was proposed for growth of the yeasts in both substrate media. Higher dry mass and lower Ks values were obtained in glucose media when compar...

The representation of biological innovations in and through communication and media practices is vital for understanding the nature of "bio-objects" and the process we call "bio-objectification." This paper discusses two ideal-typical analytical approaches based on different underlying communication models, ie, the traditional (science- and media-centered) and media sociological (a multi-layere...
