Recently, two distinct cDNA clones encoding the catalytic subunit of the vacuolar H+-ATPase (V-ATPase) were isolated from the allotetraploid cotton species Gossypium hirsutum L. cv ‘Acala SJ-2’ (Wilkins 1992, 1993). Differences in the nucleotide sequence of these clones were used as molecular markers to explore the organization and structure of the V-ATPase(More)
Prior studies in hairless mice have demonstrated that acute barrier disruption by acetone treatment increases the molecular weight (MW) cutoff of polyethylene glycol (PEG) penetration through the skin. The objective of the present study was to further investigate the dependence of permeability on MW with different forms of barrier disruption. A series of(More)
The giant radio galaxy M 87 with its proximity (16 Mpc), famous jet, and very massive black hole ((3 − 6) × 10 9 M) provides a unique opportunity to investigate the origin of very high energy (VHE; E>100 GeV) γ-ray emission generated in relativistic outflows and the surroundings of super-massive black holes. M 87 has been established as a VHE γ-ray emitter(More)
