The unusually high levels of saturation and thus order contribute to the uniqueness of
human lens membranes. In addition, and unlike in most biomembranes, most of the lens …

Timely delivery of oxygen (O2) to tissue mitochondria is so essential that elaborate
circulatory systems have evolved to minimize diffusion distances within tissue. Yet …

Carotenoids are of great interest due to their essential biological functions in both plants and
animals. However, the properties and functions of carotenoids in natural systems are …

The oxygen permeability coefficient across the membrane made of the total lipid extract from
the plasma membrane of calf lens was estimated from the profile of the oxygen transport …

Cholesterol is widely known to alter the physical properties and permeability of membranes.
Several prior works have implicated cell membrane cholesterol as a barrier to tissue …

A stable triarylmethyl spin probe whose electron paramagnetic resonance (EPR) spectrum is
highly sensitive to molecular tumbling is reported. The strong anisotropy of the hyperfine …

The most unique feature of the eye lens fiber-cell plasma membrane is its extremely high
cholesterol content. Cholesterol saturates the bulk phospholipid bilayer and induces …

Abstract Aquaporin-0 (AQP0), the primary water channel in lens fiber cells, is critical to lens
development, organization, and function. In the avascular lens there is thought to be an …

This study addresses the question: why do rats get cataracts at 2 years, dogs at 8 years, and
whales do not develop cataracts for 200 years? Whale lens lipid phase transitions were …

The influence of a variety of microenvironmental factors on the inherent reactivity of
membrane-located reagents is poorly understood. A goal of this review is to provide detailed …
