Posttraumatic Growth: The Lived Experience of Recurrent and Multiple Trauma Survivors of Kenya’s Skirmishes, 2007 Post-election Violence, and 2009 National Level Oil Tanker Fire Explosion
… has associated the benefits of posttraumatic growth (PTG) with high levels of stress and trauma that challenge the victim’s assumptive world. The literature reveals that extensive research on PTG has been done on the American, European, and Asian continents but not on the African continent. …

Manipulating the root mycobiome to improve plant performance and reduce pathogen pressure in corn (Zea mays)
… inoculation treatments that could increase the growth of corn seedlings sown in low productivity soils to that in high productivity soils and shift the root mycobiome composition. Fungal inoculation treatments did not have significantly different root mycobiome composition than seedlings grown …

Effects of co-inoculation of Delftia acidovorans RAY209 on the growth of Bradyrhizobium diazoefficiens USDA110 inoculated Glycine max
… pressure will be driven by continued population growth, an unprecedented and growing demand for high quality protein, environmental degradation caused by chemical fertilizers, and also be the need for agriculture to be more sustainable. Inoculating crops with plant growth-promoting rhizobacteria …

Regulation of macrophage activities by tumor growth: mechanisms of immunosuppression
… are all involved in the battle against tumor growth. However, other Mφ activities such as cell growth promotion, angiogenesis, and suppression of anti-tumor lymphocytes aid in tumor growth. This dissertation discusses how tumors control Mφ activities to create favorable environments for tumor …

DISCLOSING THE ROLE OF ROOT EXUDATES IN MODULATING THE INTERACTION BETWEEN PLANT AND XENOBIOTIC DEGRADING BACTERIA
… strain, to observe root colonization and plant-growth-promotion potential upon stress. Our findings indicated that flavonoids stimulated LB400 proliferation, induced PCB degradation potential and increased biofilm formation, swimming motility and chemoattraction, features overall implicated in …

Evaluation of antibacterial activity of plant-food by-products and their potential application in livestock animals
… of antibiotics, especially in food animals for growth promotion and disease prevention, promote the development of antibiotic resistance, which poses a severe threat to health of humans and animals. To slow the pace of antibiotic resistance and preserve the efficacy of antibiotics for both human …

Plant genotype, immunity and soil composition control the rhizosphere microbiome
… with 10 % soil initially, and with 10% of growth medium from the previous generation in generations 2 and 3, keeping replicates separate for all three generations. The microbiome community structure of the plant rhizosphere in each generation was characterised using ARISA DNA fingerprinting …

Arabidopsis thaliana P4-type ATPases ALA4 and ALA5 are Necessary for Normal Cellular Elongation in Developing Vegetative Tissues and Rescue the Pollen Tube Deficiencies in Knockout ala6/7 Mutants
… activities that are critical for normal growth and development of vegetative tissues. A double loss of function mutant for ala4/5 results in dwarfism for all vegetative tissues, including roots, leaves and hypocotyls. Selected cell types in these tissues were shown to be smaller. While a …

Studies on the occurrence of antibiotic-resistant bacterial strains from agriculture-associated waters and their proteomic and genomic characterizations
… uses of antibiotics for therapeutic purposes and growth promotion in cattle are the major factors for the spread of antimicrobial drug resistance. Exposure of sub lethal levels of antibiotics to pathogenic microorganisms leads to the development of resistance, which then in due course spreads to …

Integrative analysis of high-throughput biological data: shrinkage correlation coefficient and comparative expression analysis
… to discover what genes changed expression during growth suppression. We evaluated the gene expression changes of apyrase-suppressed RNAi mutants that had been grown in the light and in the darkness, using the NimbleGen Arabidopsis thaliana 4-Plex microarray, respectively. We compared the two sets …

Phytohormones and the Culture of Agaricus bisporus (Lange) Pilat
… bisporus culture matte promoted mycelial growth significantly at concentrations of 16° - 107 M. Most of the tested phytohormones were more effective in growth promotion in liquid culture rather than on semi-solid agar . Phytohormones stimulated hyphal cell division and cell elongation . …

The Plant Growth-Promoting Potential of Root-Associated Bacteria from Plants Growing in Stressed Environments
… studies have demonstrated the potential of plant growth-promoting bacteria, including their use as inoculants, in the contexts of both agriculture and enhanced phytoremediation. Despite their promise, there is still a need to characterize and identify plant growth-promoting bacteria amidst …

Interactions Between Nutrition and Health or Stress in Poultry
… results indicated that the NPP requirement for growth of 8- to 22-d old chicks may be reduced by high temperatures (37 C). A NPP deficiency, however, may result in increased mortality in older chicks exposed to an acute increase in temperature. Four experiments were conducted to evaluate the …
