The role of chloride in the lens of the eye [PDF]
Experimental Physiology, 1997 Until recently, the investigation of membrane ion transport mechanisms and their relationship with cataract formation has mainly focused on sodium, potassium and calcium. The specific role of chloride in solute transport within the lens has been given little attention. Rather, chloride was considered as simply the counterion to sodium.

Perfect imaging with positive refraction in three dimensions [PDF]
, 2009 Maxwell's fish eye has been known to be a perfect lens within the validity range of ray optics since 1854. Solving Maxwell's equations we show that the fish-eye lens in three dimensions has unlimited resolution for electromagnetic ...

Amino Acids, 2006 The eye lens is a fascinating organ as it is in essence living transparent matter. Lenticular transparency is achieved through the peculiarities of lens morphology, a semi-apoptotic process where cells elongate and loose their organelles and the precise molecular arrangement of the bulk of soluble lenticular proteins, the crystallins.

A Model for Investigating Developmental Eye Repair in Xenopus Laevis [PDF]
, 2018 Vertebrate eye development is complex and requires early interactions between neuroectoderm and surface ectoderm during embryogenesis. In the African clawed frog, Xenopus laevis, individual eye tissues such as the retina and lens can undergo regeneration.

A Complex Lens for a Complex Eye [PDF]
Integrative and Comparative Biology, 2017 A key innovation for high resolution eyes is a sophisticated lens that precisely focuses light onto photoreceptors. The eyes of holometabolous larvae range from very simple eyes that merely detect light to eyes that are capable of high spatial resolution.
