A new species of Acanthocotyle Monticelli, 1888 (Platyhelminthes: Monogenea: Acanthocotylidae) from the ventral skin of the banded stingaree, Urolophus cruciatus (Lacépède, 1804), from Tasmania, Australia.

Acanthocotyle urolophi sp. nov. is described from the skin of the banded stingaree, Urolophus cruciatus (Lacépède, 1804).

A new species of Entobdella Blainville in Lamarck, 1818 (Monogenea: Capsalidae: Entobdellinae) from the Greenland halibut, Reinhardtius hippoglossoides.

A previously undescribed species of Entobdella is reported from the skin of the Greenland halibut, Reinhardtius hippoglossoides (Pleuronectiformes, Pleuronectidae). Entobdella whittingtoni sp. nov.

Effect of total lens epithelial cell destruction on intraocular lens fixation in the human capsular bag.

Purpose: To evaluate the effect of complete destruction of lens epithelial cells (LECs) in the capsular bag on intraocular lens (IOL) stability.

Setting: School of Biological Sciences, University of East Anglia, Norwich, United Kingdom.

Design: Comparative evaluation.

Chemically-coupled-peptide-promoted virus nanoparticle templated mineralization.

The external surface of the plant virus Cowpea mosaic virus (CPMV) can be chemically modified with peptides that direct specific mineralization processes. Subsequent mineralization of the peptide-CPMV conjugates produces monodisperse nanoparticles of ca. 32 nm diameter coated with, for example, cobalt-platinum, iron-platinum or zinc sulfide, which cannot be readily prepared by other methods.

A new method to obtain epithelial and stromal explants from human Corneo-Scleral Discs for the routine culture of corneal epithelial and fibroblast cells.

Acquisition of human corneal cells for culture is hindered not only by the scarcity of donor tissues but also by some of the standard enzymatic and mechanical isolation techniques. Good yields have been reported from full-thickness explant and sclero-limbal pieces. However, due to their greater proliferative capacity, fibroblasts will encroach and subsequently overwhelm epithelial cultures whichever technique is used.

Cadmium-specific formation of metal sulfide 'Q-particles' by Klebsiella pneumoniae.

Klebsiella pneumoniae overcomes cadmium toxicity through the 'biotrans-formation' of cadmium ions into photoactive, nanometre-sized CdS particles deposited on the cell surface. The kinetics of particle formation during batch culture growth was monitored by electron microscopy (EM), energy-dispersive X-ray analysis and electronic absorption spectroscopy (EAS). During the deceleration phase of bacterial growth, the presence of CdS particles on the outer cell wall of K.
