Recent studies have demonstrated resistance of membrane function to cold in several tissues of hibernating mammals. Thus, in hamsters or ground squirrels excitability of nerves (Chatfield et al., 1948; Kehl and Morrison, 1960) and cardiac muscle (see Marshall and Willis, 1962) is maintained at low temperatures, the resting membrane potential of atrial fibers is virtually unchanged by temperatur...

Scleredema is a form of cutaneous mucinosis caused by an increased accumulation of collagen and mucin in the dermis. It is characterized by diffused, nonpitting swelling and induration of the skin. Scleredema diabeticorum is one type of scleredema associated with diabetes mellitus. AIDS-related insulin resistance and lipodystrophy syndrome are a newly emerging entities in HIV-infected patients ...

Increasing concentrations of ions flowing through the xylem of plants produce rapid, substantial, and reversible decreases in hydraulic resistance. Changes in hydraulic resistance in response to solution ion concentration, pH, and nonpolar solvents are consistent with this process being mediated by hydrogels. The effect is localized to intervessel bordered pits, suggesting that microchannels in...

Effects of guayule resin on mechanical, physical, and biological performance wood strand-based panels were evaluated. Southern yellow pine (Pinus spp. L) strands mixed with phenol formaldehyde (PF) to a target content 5% hot-pressed manufacture panels. A solution was prepared sprayed the immediately after PF different contents 0.5% 1.0%. Specimens cut from treated control subjected tensile, int...

The aim of this work is to study the effect irradiation with low-energy Kr14+ ions an energy 280 keV on radiation swelling and a decrease in strength characteristics high-entropy alloys based TiTaNbV system. prospects these studies are due possibility obtaining new data resistance alloys, which have great potential for use as structural materials new-generation reactors. choice type dose 5 × 10...

During periods of high activity neurons are expected to swell due to the uptake of Cl(-). To find out whether leech Retzius neurons possess swelling-activated Cl(-) channels that facilitate Cl(-) efflux and, hence, volume recovery, we exposed the cells to hypotonic solutions. In hypotonic solutions, the cells slowly swelled but did not undergo a regulatory volume decrease. However, the cell vol...

Peptidoglycan, the substance in mycobacteria thought to be responsible for inducing adjuvant arthritis, and endotoxin (lipopolysaccharide or LPS) share many inflammatory properties. Since repeated administration of LPS produces tolerance, i.e., resistance to the toxic and inflammatory effects of LPS, we tested whether LPS and/or LPS tolerance might influence inflammation due to mycobacterial ad...
