Dissolution limited bioavailability is a very c...

Intermolecular forces tend to organize water molecules into a tetrahedral lattice, conferring "crystalline" properties on the liquid. The simple ions, such as Na+, K+, and Cl-, have dinmensions which are of the same order as the water nmolecule. Therefore, in aqueous solution, ions can substitute for water molecules in the water lattice. However, because the force between ion and water molecule...

BACKGROUND Hydrazones and their metal complexes were heavily studied due to their pharmacological applications such as antimicrobial, anticonvulsant analgesic, anti-inflammatory and anti-cancer agents. This work aims to synthesize and characterize novel complexes of VO(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Zr(4+)and Pd(2+) ions with oxalo bis(2,3-butanedione-hydrazone). Single crystals of the li...

The effects of tight junction structure on water and solute fluxes across proximal tubular epithelium were examined with fiber-matrix equations previously derived by Curry and Michel (1980. Microvascular Research. 20:96-99). Using plausible estimates of tight junction fiber length and width the model predicts solute (Ps) and water permeability (Lp) coefficients that agree with the measured valu...

The permeability of the outer mitochondrial membrane to most metabolites is believed to be based in an outer membrane, channel-forming protein known as VDAC (voltage-dependent anion channel). Although multiple isoforms of VDAC have been identified in multicellular organisms, the yeast Saccharomyces cerevisiae has been thought to contain a single VDAC gene, designated POR1. However, cells missin...

Earlier studies showed that exposure of the isolated urinary bladder of the toad to vasopressin produces striking increases in passive permeability to water and urea as well as increases in active transport of Na-(1-4). Bentley (5) observed that raising the concentration of Ca++ in the sero-sal bathing medium depressed the response to a 1 mU per ml concentration of vasopressin, as measured by t...

Synaptosomes swell rapidly in isosmotic solutions of glycerol or urea, but the swelling in solutions of larger non-electrolytes. such as erythritol, glucose or sucrose is slower. The permeability of synaptosomes to non-electrolytes is temperature dependent, and the low activation energies for the permeation of urea (13 kcdl/mol) and erythritol (9.5 kcal/mol) indicate that the penetration of non...
