The MICA 2008 conference was held May 1–3, 2008 in Stonehaven Bay, Trinidad. The conference honoured the scientific career of Keith Geddes. Colleagues, students and friends celebrated Professor Geddes’ achievements in many areas: in fundamental research, in technology transfer, and in the training of the next generation of scientists, mathematicians and engineers. Keith received his PhD in 1973...
متن کاملAntibiotic Sensitivity of Bacillus clausii Strains in Commercial Preparation
Recently has been acknowledged the healthy use of Bacillus and related bacteria as probiotics. A mixture reported to contain four probiotic strains of Bacillus clausii is marketed as an OTC (Over The Counter) medicinal supplement for human use. Their poliantibiotic resistant property, useful for restoring the gut microbiota during antibiotic treatment, raises the question about the risk of resi...
متن کاملSublethal stress: Impact of solar UV radiation on protein synthesis in the copepod Acartia tonsa.
Aquatic organisms respond to environmental challenges such as thermal stress with the rapid induction of highly conserved polypeptides known as stress proteins or heat shock proteins (Hsps). Solar ultraviolet radiation (UVR, 280-400 nm) is an important environmental stressor in marine ecosystems. Here, we present results of experiments conducted with the marine copepod Acartia tonsa to follow t...
متن کاملPollen sensitivity to ultraviolet-B (UV-B) suggests floral structure evolution in alpine plants
Various biotic and abiotic factors are known to exert selection pressures on floral traits, but the influence of ultraviolet-B (UV-B) light on the evolution of flower structure remains relatively unexplored. We have examined the effectiveness of flower structure in blocking radiation and the effects of UV-B on pollen viability in 42 species of alpine plants in the Hengduan Mountains, China. Flo...
متن کاملInhibition of excision repair without influence upon UV-sensitivity and UV-mutability in Escherichia coli B/r Hcr+.
Pre-irradiation starvation of exponentially growing Escherichia coli B/r Hcr+ thy-try- strain for thymine and tryptophan causes inhibition of pyrimidine dimer excision from ultraviolet damaged cells DNA. This inhibition of excision repair has not resulted in increasing ultraviolet sensitivity nor in increasing frequency of ultraviolet induced tryptophan revertants. The possible mechanisms of th...
