Description

Application

Epithelial transport and bioavailability of intranasally administered human growth hormone formulated with the absorption enhancers didecanoyl-L-alpha-phosphatidylcholine and alpha-cyclodextrin in rabbits.: This research explores the bioavailability and epithelial transport of intranasally administered human growth hormone, highlighting the role of phosphatidylcholine as an absorption enhancer. (Agerholm et al., 1994).

Biochem/physiol Actions

A major structural phospholipid in brain, comprising approx. 15% of total lipid; primarily localized to gray matter.

Manipulation of charge distribution in the arginine and glutamate clusters of the OmpG pore alters sugar specificity and ion selectivity.

Christine Schmitt et al.

Biochimica et biophysica acta. Biomembranes, 1861(10), 183021-183021 (2019-07-16)

OmpG is a general diffusion pore in the E. coli outer membrane with a molecular architecture comprising a 14-stranded β-barrel scaffold and unique structural features. In contrast to other non-specific porins, OmpG lacks a central constriction zone and has an

Paramagnetic Fluorinated Nanoemulsions for in vivo F-19 MRI.

Junsung Rho et al.

Molecular imaging and biology, 22(3), 665-674 (2019-09-05)

We aim to develop perfluorocarbon-based nanoemulsions with improved sensitivity for detection of inflammatory macrophages in situ using F-19 MRI. Towards this goal, we evaluate the feasibility of nanoemulsion formulation incorporating a metal chelate in the fluorous phase which shortens the

Role of hyaluronic acid and phospholipid in the lubrication of a cobalt-chromium head for total hip arthroplasty.

Jong-Bong Park et al.

Biointerphases, 9(3), 031007-031007 (2014-10-05)

The tribological performance of total hip arthroplasty has an important influence on its success rate. This study examined the concentration-dependent role of hyaluronic acid (HA) and phospholipid (dipalmitoylphosphatidylcholine, DPPC) in the boundary lubricating ability of retrieved cobalt-chromium femoral heads.
