Abstract:
The approach that most animal cells employ to regulate intracellular pH (pHi) is not too different conceptually from the way a sophisticated system might regulate the temperature of a house. Just as the heat capacity (C) of a house minimizes sudden temperature (T) shifts caused by acute cold and heat loads, the buffering power (β) of a cell minimizes sudden pHi shifts caused by acute acid and alkali loads. However, increasing C (or β) only minimizes T (or pHi) changes; it does not eliminate the changes, return T (or pHi) to normal, or shift steady-state T (or pHi). Whereas a house may have a f

Abstract:
Abstract Glycans, as a part of glycoproteins, glycolipids and other glycoconjugates, are involved in many vital intra- and inter-cellular tasks, such as protein folding and sorting, protein quality control, vesicular trafficking, cell signalling, immunological defence, cell motility and adhesion. Therefore, their correct construction is crucial for the normal functioning of eukaryotic cells and organisms they form. Most cellular glycans are constructed in the Golgi, and abnormalities in their structure may derive, for instance, from alkalinization of the Golgi lumen. In this work we show th

Abstract:
Abstract Consideration of the exact degree of dissociation of all the weak acids involved in bacterial metabolisms shows that the SRB's regulate: the pH of their environment, at levels which depend on the potential secondary reactions: precipitation of FeS, oxidation of HS- to S2O3- - by traces of oxygen, metabolisation of this thiosulfate, or of other sulfur compounds. It is possible in this way to explain the initiation and growth of bacterial corrosion pits, the specificity of certain metabolisms, particularly mixotrophic ones, or the aggravating effect of oxygen ingress in H2S media.

Abstract In many years transport of dry liquefied CO2 has been carried out using pipelines made from low alloy carbon steel without any corrosion problems. Drying CO2 increases the handling cost and necessitate installation of additional equipment. The latter is especially important for offshore installations where space and weight of equipment are issues of concern. In the present work the corrosion rate on low alloy carbon steel exposed to water at very high CO2 pressures have been investigated. The effect of pH regulation and a film forming corrosion inhibitor have been tested as well.

Simultaneously, they impart hydrophobicity to coatings, preventing water intrusion and resulting in surface self-cleaning effects. This multifunctionality delivers long-lasting corrosion protec

Abstract:
Gene regulation at the RNA level encompasses multiple mechanisms in prokaryotes and eukaryotes, including splicing, editing, endo- and exonucleolytic cleavage, and various phenomena related to small or interfering RNAs. Ribonucleases are key players in nearly all of these post-transcriptional mechanisms, as the catalytic agents. This proposal continued BARD-funded research into ribonuclease activities in the chloroplast, where RNase mutation or deficiency can cause metabolic defects and is often associated with plant chlorosis, embryo or seedling lethality, and/or failure to tolerate nutrient
