It has been confirmed that the rabbit vermiform appendix secretes spontaneously at a relatively rapid rate (1-12 ml.h(-1); 1.4+/-0.24 mul.min(-1).cm(-2)). The electrolyte composition is similar to that of ileal fluids and independent of the secretory rate. The transmural potential difference is about 12 mV, mucosa negative. Of the major electrolytes, only HCO(3) (-) is secreted grossly against ...

MUT, Z. and H. AKAY, 2010. Effect of seed size and drought stress on germination and seedling growth of naked oat (Avena sativa L.). Bulg. J. Agric. Sci., 16: 459-467 Effects of seed size and osmotic stress on germination and seedling growth of five naked oat genotypes were investigated in this study. Oat genotypes were Mozart, CROA 60, Detvan, Eva 1 and AC Belmont. Small, medium and large seed...

Osmotic and turgor adjustment in roots, shoots, and whole sporophytes of a NaCI-tolerant mutant and a NaCI-sensitive wildtype strain of the fern Ceratopteris richardii Brongn. were charactenzed following exposure to 60 millimolar NaCI, using a psychrometric approach to pressure-volume analysis. Water potential components of whole plants and shoots at full or ambient hydration were similar betwe...

We give an explicit formula for the membrane potential of cells in terms of the intracellular and extracellular ionic concentrations, and derive equations for the ionic currents that flow through channels, exchangers and electrogenic pumps based on simple energy considerations and conservation laws. We demonstrate that the work done by the pump is equal to the potential energy of the cell plus ...

Water relations and growth of maritime pine (Pinus pinaster Ait.) were investigated in 2-year-old seedlings of French ('Landes'), Iberian ('Iberian') and Moroccan ('Tamjoute') origin raised for 67 days in a flowing solution culture system containing 0, 50, 150 or 250 mM NaCl. Height growth, and stem, needle and root dry matter were reduced by salinity with minor differences among geographic ori...

We examined the extent of osmotic adjustment and the changes in relative water content (RWC) and transpiration rate (i.e., relative stomatal function) that occur in water-deficit-conditioned 6-year-old Thuja occidentalis L. (eastern white cedar) trees in response to a severe drought. Trees conditioned by successive cycles of mild or moderate nonlethal water stress (conditioning) and nonconditio...

Bubbles can be trapped inside textured structures such as grooves, forming a superhydrophobic surface. A superhydrophobic surface has a large effective hydrodynamic slip length compared to a smooth hydrophobic surface and holds the promise of enhancing electrokinetic flows that find many interesting applications in microfluidics. However, recent theoretical studies suggested that electro-osmoti...

The main objectives of this study were to determine the occurrence and potential causative factors of Immune-mediated hemolytic anemia (IMHA) in native cattle and water buffaloes from southwest of Iran. Fifty-three anemic animals (37 cattle and 16 buffaloes) were studied. A full clinical history and physical examinations were undertaken for all animals. Four clinically healthy cattle and four h...

Background: Intracytoplasmic sperm injection (ICSI) can be considered the solstice in vitro insemination technique because it has powerfully allowed the treatment of male factor infertility, but in this procedure, except visual morphological selection, there is no standardization for sperm selection. Recently, hypo osmotic swelling test (HOST) has been proposed to have the potential to select i...
