Abstract: The distal tubule defines the final section of the renal tubule, and can be subdivided into four segments: distal tubule, connecting segment (which was previously considered part of the distal tubule), cortical collecting duct and medullary collecting tubule.

Endothelins and Kidney Acidification
2011Endothelins (ETs) were initially identified for their vasoactive properties, but they also influence kidney tubule transport including acidification. They contribute importantly to enhancing kidney acidification in response to an acid challenge to systemic acid-base balance and enhance tubule acidification in settings of chronically reduced glomerular ...

Acidification, metals and macrophytes
Environmental Pollution, 1991Plant-specific and metal-specific uptake of Al, Cd, Pb and Hg are reviewed, using examples from bryophytes, lichens, wetland plants, woody plants and crop plants. Ranges of plant metal concentration, toxic thresholds and effects, and effects of metal on biomass are derived from the literature.

Acidification of Lysosomes and Endosomes
1996Lysosomes, endosomes, and a variety of other intracellular organelles are acidified by a family of unique proton pumps, termed the vacuolar H(+)-ATPases, that are evolutionarily related to bacterial membrane proton pumps and the F1-F0 H(+)-ATPases that catalyze ATP synthesis in mitochondria and chloroplasts.

Acidification and Protein Traffic
2003Acidification of some organelles, including the Golgi complex, lysosomes, secretory granules, and synaptic vesicles, is important for many of their biochemical functions. In addition, acidic pH in some compartments is also required for the efficient sorting and trafficking of proteins and lipids along the biosynthetic and endocytic pathways.

Atmospheric Acidification in the Asian Region
Environmental Monitoring and Assessment, 1991Atmospheric acidification in the Asian region is discussed from the perspectives of currently available regional measurements, and the knowledge now available from several decades of acidic deposition research in the northern mid-latitudes. The main conclusions emerge: (1) that there is insufficient information currently available to enable a ...
