The deposition and localization of benzo(a)pyrene (BP) suspended in a gelatin-0.9 percent NaCl solution was studied in hamster lungs by ultraviolet fluorescence microscopy. BP was deposited primarily in the alveolar region of the lung. Although large numbers of BP-filled macrophages were seen in the upper airways by 24 hr after an instillation, little BP appeared to penetrate into the bronchial...

Gavage of 2 M NaCl (IG 2 M NaCl), a procedure to induce cell-dehydration-and water and 0.15 M NaCl intake in a two-bottle choice test-is also a potential gastric irritant. In this study, we assessed whether mineral intake induced by IG 2 M NaCl is associated with gastric irritation or production of pica in the rat. We first determined the amount of mineral solution (0.15 M NaCl, 0.15 M NaHCO3, ...

In this research, the accelerated ripening of the Kabkab dates from Khalal to Tamr using NaCl and acetic acid solutions was studied. Fruits at Khalal stage were harvested and washed with distilled water before being treated with ripening inducers: 1. NaCl solutions, 2. acetic acid solutions and 3. Aqueous solution of NaCl (1%) and acetic acid. moisture, pH, colour, brix and textural firmness of...

The whole cell recording mode of the patch-clamp technique was used to study the effect of hypotonic NaCl or isotonic high-KCl solution on membrane currents in a human osteoblast-like cell line, C1. Both hypotonic NaCl or isotonic high-KCl solution activated Cl- channels expressed in these cells as described previously. The reversal potential of the induced Cl- current is more negative when act...

The DNA damage caused by TiO2 under in vitro conditions by UV-A exposure in the presence of anionic vesicles of Aerosol OT (AOT) was investigated. The supercoiled form (S) in DNA plasmids was converted to the linear form (L) via the relaxed form (R). The DNA damage was slower in the presence of AOT vesicles prepared in aqueous NaCl solution. Moreover, the presence of AOT vesicles in solution af...

In an enclosure-type study, I investigated the use of odor, auditory, and visual cues to enhance lithium-chloride (LiCl)induced prey aversion in coyotes (Canis latrans). Eight adult, male, wild-caught coyotes that killed 2 adult sheep during successive daily, 1 -hr trials were assigned to LiCland sodium-chloride (NaCl)-bait groups. The 4 LiCl-bait coyotes were sequentially presented with leg-of...

Synthesis of a nanoporous alumina membrane (NPAM) by the two-step anodization method and its morphological and chemical surface characterization by analyzing Scanning Electron Microscopy (SEM) micrographs and X-Ray Photoelectron Spectroscopy (XPS) spectra is reported. Influence of electrical and diffusive effects on the NaCl transport across the membrane nanopores is determined from salt diffus...

in this work we have applied the dense system equation of state (dseos) to electrolyte solutions. we have found that this equation of state can predict the density of electrolyte solutions very accurately. it has been tested for different electrolytes solutions at different temperatures and compositions. a hypothetical binary model has been applied to find the dependencies of parameters of this...

NaCl, KCl, or PEG (polyethylene glycol)-amended potato dextrose broth (PDB), and potato dextrose agar (PDA) are essential for pure culture studies of water stress on fungi. Direct information on the actual water potential (WP) of this salt-amended PDB and PDA is lacking. Much fungal research in the past calculated WP of these salt-amended growth media by adding the WP of their constituents take...
