Stress response of porphyromonas gingivalis
The heat shock response of Porphyromonas gingivalis was examined by one-and two-dimensional polyacrylamide gel electrophoresis after metabolic labeling with (14C)-amino acids. When P. gingivalis cells were shifted from 37°C to 42°C, elevated synthesis of four proteins with the apparent molecular …

STRESS RESPONSE OF STATIC PARTICULATE MEDIA
… description. We study the manner in which local stresses are redistributed in response to localized force perturbations. We first study stress response in frictionless and frictional shallow, ordered, granular arrays confined by solid boundaries for a range of system sizes. Stress response …

Transcriptional stress response in foodborne pathogens
… differential expression of genes and elucidating stress responses. Effective methods and treatments require an understanding of intervention (e.g. sanitizers) and treatment (e.g. antibiotics) mechanisms and efficacies. Accurate novel molecular method use requires proper learning of theory and data …

MicroRNA Function in Cellular Stress Response
… and responding to changing environments and stress conditions as for viability or development. In this dissertation, two studies are presented: The first study demonstrates a role for microRNA in the regulation of oxidative stress response in erythroid cells and the functional consequences of …

Extracytoplasmic stress response systems in S. Typhimurium
… gene expression following activation of certain stress response systems. In gram negative bacteria such as Salmonella, envelope stress responses (ESR) are response systems that target stresses affecting components of the cell envelope such as the periplasm and outer membrane proteins. The two …

Systems analysis of stress response in plants
The response of plants to environmental stress spans several orders of magnitude in time and space, causing system-wide changes. These changes comprise of both protective responses and adverse reactions in the plant. Stresses like water deficit or drought cause a drastic effect in crop yield, while …

Defining the ethanol-stress response in Saccharomyces cerevisiae
… yeast performance, acting as a potent chemical stress on yeast cells. This stress eventually inhibits yeast growth and reduces ceil viability, therefore limiting alcohol concentrations in the final product and increasing fermentation turnover times. The reduced cell growth rate and viability, as …

Stress response genes in the human proximal tubules
… line could provide a model system to study the stress response of the proximal tubule cell. Heat stress, elevated temperature at 42.5°C for 1 hr, caused a marked increase only in hsp 70 mRNA and protein, but not that of hsp 27 or hsp 60 mRNA and protein. Similar results were obtained when …

An examination of novel archaeal stress response genes
… underlying gene regulatory systems, the stress response in the thermophilic archaeon, Thermococcus zilligii, was examined. Microorganisms respond to stress by triggering physiological and morphological changes, which are largely brought about by adaptive changes in gene expression. The …

Regulation of The Oxidative Stress Response By Arid1A
… cancers.</p> <p> In this study, drug responses between <em>ARID1A</em>-wildtype and <em>ARID1A</em>-mutant cell lines were compared using the ‘Genomics of Drug Sensitivities in Cancer’ database. From this analysis, I found that <em>ARID1A</em>-mutant cell lines are more sensitive to …

Studies on the stress response in Fusobacterium nucleatum.
… such as glucose, galactose and fructose. Its response and adaptation to stressful environmental conditions such as pH is unknown. The overall aim of this study was, therefore, to determine how F. nucleatum copes with environmental stresses induced by pH changes. F. nucleatum was grown by …

Magnetic Barkhausen Noise Testing: Steel Grades and Stress Response
… are sensitive to microstrutural variations and stress states of the material, which can adversely affect magnetic properties or structural integrity of engineering components. Therefore, magnetic Barkhausen noise has potential as a non-destructive testing technique for indirect materials …

The Adolescent Stress Response to a Naturalistic Driving Stressor
… Adolescents' subjective and physiological responses to a driving simulator task were assessed. Anxiety was measured via self report and salivary cortisol. Participants provided a baseline saliva sample and 3 post-task samples for cortisol analysis. Subjective anxiety scores were obtained at …

The Role of the Stress Response Gene Gadd45b in Senescence
… Gadd45b, and Gadd45g) has been shown to act as stress sensors in response to various physiological and environmental stressors, including oncogenic stress. However, the role of Gadd45b in senescence remained unclear. Here, we show for the first time that primary mouse embryo fibroblasts (MEFs) …
