purpose : to investigate the effects of mtp-131 on trabeculum cells cultured under hydrostatic pressure methods : glaucomatous human trabecular meshwork (gtm3) cells were divided into three groups: the mtp-131 group, the hydrostatic group, and the normal group. the mtp-131 group was pretreated with 1 µm mtp-131, and the cells were then cultured under 80 mmhg pressure for 24 hours. the normal gr...

This study investigates the buckling behavior of short cylindrical shells with hemi-spherical heads subjected to hydrostatic pressure. It is assumed that the length of the cylindrical part is smaller than or equal to its diameter while its material may be dif-ferent from that of hemispherical heads. Finite element analysis was used to seek out the effect of geometric parameters such as thicknes...

objective: hydrostatic pressure is crucial component of cell environment and fundamental physical quantity, also it is the main factor of both cell integrity and function. pressure variation disorder, beyond physiological limits, may lead to pathological states. in this study, we examined the effect of hydrostatic pressure on apoptosis induction, viability, morphology, adhesion potency to subst...

In this paper, drain-source current, transconductance and cutoff frequency in AlGaN/GaN high electron mobility transistors have been investigated. In order to obtain parameters of exact AlGaN/GaN high electron mobility transistors such as electron density, the wave function, band gap, polarization charge, effective mass and dielectric constant, the hydrostatic pressure and temperature effects a...

Dear Editor: Miyamoto et al show that intravitreal triamcinolone reduces macular edema as early as 1 hour after injection. They suggest that the time pattern demands that nongenomic mechanisms must be involved in the therapeutic effect of triamcinolone on retinal edema. Vasogenic edema in all tissues, including the retina, may be understood in terms of Starling’s law, by which the balance of hy...

Background: Cryopreservation of ovaries is an important technique in assisted reproduction technology. Physical forces like hydrostatic pressure have a pivotal role in reproduction systems. Due to changes in intrafollicular pressure during ovulatory process, this study designed to examine the effects of hydrostatic pressure on oocyte maturation and cell death in cumulus cells from cryopreserved...

When hydrostatic pressure across epithelia fixed between a Ussing-type chamber was oscillated mechanically, the membrane potential was found to oscillate synchronously. When the transepithelial potential was oscillated artificially, the hydrostatic pressure difference also oscillated synchronously. Under such oscillating gradient conditions, concentration changes in the unstirred layer can be m...
