Replacing R-22 by HFC refrigerants in stationary air conditioners is forcing oil producers to develop a new lubricant which has good miscibility with HFC, lubricity and electric resistivity. Mitsui has selected a carbonate compound for a new lubricant candidate with HFC and developed it forcusing on its thermal stability, which is one of the most important factors to get good lubricity. By supp...

Two-component Langmuir monolayers formed on a subphase of 0.5M sodium chloride solution were investigated for two different cerebrosides (LMC-1 and LMC-2) with steroids of cholesterol (Ch) and cholesteryl sodium sulfate (Ch-S); i.e. LMC-1/Ch, LMC-1/Ch-S, LMC-2/Ch, and LMC-2/Ch-S were examined in terms of surface pressure (pi), the surface potential (DeltaV) and the dipole moment (mu( perpendicu...

Differential effects of pressure or volume overload on myocardial MMP levels and inhibitory control. Am. J. Physiol. Heart Circ. Physiol. 278: H151–H161, 2000.—Left ventricular (LV) pressure (PO) or volume (VO) overload is accompanied by myocardial remodeling...

Slightly increased pressure stimulates tumor cell adhesion and proliferation. In the present study, we aimed to evaluate the effects of high pressure on gene expression and the biological behavior of gastric cancer cells. After incubation for 30 min at 37˚C under ambient and increased pressure, one portion of SGC7901 cells was used for cell proliferation and apoptosis assays, cell cycle analysi...

The studies on Langmuir monolayer of cholesteric acid (ChA) at the air-water (A-W) interface show many interesting results. We have observed different two-dimensional (2D) phases like L′1, L ′ 2 and L2. In this chapter, we describe our studies on the stability of the phases and miscibility of binary mixture of ChA and lipid molecules of different structures. We have chosen the lipid molecules l...

The pressure–composition (PC) behavior of deuterium in single crystal Pd has been measured over a temperature range extending from room temperature to 393 K. These data allow the determination of (i) relative partial molar enthalpy and entropy, without the contribution of the configuration entropy, for the dilute solid solution phase, (ii) enthalpy and entropy change characterizing the a→a9 pha...

Lower-extremity veins have efficient wall structure and function and competent valves that permit upward movement of deoxygenated blood toward the heart against hydrostatic venous pressure. Matrix metalloproteinases (MMPs) play an important role in maintaining vein wall structure and function. MMPs are zinc-binding endopeptidases secreted as inactive pro-MMPs by fibroblasts, vascular smooth mus...
