Artificial ocean alkalinization (AOA) is investigated as amethod tomitigate local ocean acidification and protect tropical coral ecosystems during a 21st century highCO2 emission scenario. Employing an Earth systemmodel of intermediate complexity, our implementation of AOA in theGreat Barrier Reef, Caribbean Sea and SouthChina Sea regions, shows that alkalinization has the potential to countera...

The possibilities for interactions between toxicants and ocean acidification are reviewed from two angles. First, it is considered how toxicant responses may affect ocean acidification by influencing the carbon dioxide balance. Second, it is introduced, how the possible changes in environmental conditions (temperature, pH and oxygenation), expected to be associated with climate change and ocean...

[1] It is commonly believed that fine-textured soils developed on carbonate parent material are well buffered from possible acidification. There are no data, however, that document resistance of such soils to acidic deposition exposure on a timescale longer than 30–40 years. In this paper, we report on directly testing the long-term buffering capacity of nineteenth century forest soils develope...

We reported previously [Kataoka, Muroi, Ohkuma, Waritani, Magae, Takatsuki, Kondo, Yamasaki and Nagai (1995) FEBS Lett. 359, 53-59] that prodigiosin 25-C (one of the red pigments of the prodigiosin group produced by micro-organisms like Streptomyces and Serratia) uncoupled vacuolar H+-ATPase, inhibited vacuolar acidification and affected glycoprotein processing. In the present study we show tha...

We previously reported prevention of urolithiasis and associated rat urinary bladder tumors by urine acidification (via diet acidification) in male rats treated with the dual peroxisome proliferator-activated receptor (PPAR)alpha/gamma agonist muraglitazar. Because urine acidification could potentially alter PPAR signaling and/or cellular proliferation in urothelium, we evaluated urothelial cel...

Phagocytosis holds a central position in the development of a successful innate immune response and in the initiation of the corresponding adaptive response. The destruction of invading pathogens and the presentation of their antigens to lymphoid cells require acidification of the phagosomal lumen. The present review discusses the mechanism of phagosome acidification, with particular reference ...

Ocean acidification is increasingly recognized as a component of global change that could have a wide range of impacts on marine organisms, the ecosystems they live in, and the goods and services they provide humankind. Assessment of these potential socio-economic impacts requires integrated efforts between biologists, chemists, oceanographers, economists and social scientists. But because ocea...
