Stability of the Inverted Hexagonal Phase
The inverted hexagonal phase (HII) belongs to the biologically most significant nonlamellar lipid phases in biomembranes. Hence the geometric properties and conditions of transition to the HII phase are nowadays widely studied. In this chapter we offer a brief overview on the mechanics of the HII lipid phase. In our derivation of the free energy of lipid monolayers, we assume that lipid molecul...

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Effect of acyl chain composition on salt-induced lamellar to inverted hexagonal phase transitions in cardiolipin.
Salt-induced fluid lamellar (L alpha) to inverted hexagonal (HII) phase transitions have been studied in diphosphatidylglycerols (cardiolipins) with different acyl chain compositions, using 31P nuclear magnetic resonance (NMR) spectroscopy. Cardiolipins with four myristoyl chains, tetramyristoyl cardiolipin (TMCL), and with four oleoyl chains, tetraoleoyl cardiolipin (TOCL), were synthesized ch...
متن کاملAn inverted hexagonal phase of cationic liposome-DNA complexes related to DNA release and delivery.
A two-dimensional columnar phase in mixtures of DNA complexed with cationic liposomes has been found in the lipid composition regime known to be significantly more efficient at transfecting mammalian cells in culture compared to the lamellar (LalphaC) structure of cationic liposome-DNA complexes. The structure, derived from synchrotron x-ray diffraction, consists of DNA coated by cationic lipid...
متن کاملSimulations of Inverted Hexagonal Lipid Structures
Phospholipid molecules are composed of multipolar headgroup and two electrically neutral hydrocarbon tails. The inverted hexagonal phase (HII ) belongs to the biologically most significant non-lamellar phospholipid phases in biomembranes. Hence the geometric properties and conditions of transition to the HII phase are nowadays widely studied. In our derivation of the free energy of lipid monola...
