One-year outcomes using ranibizumab for neovascular age-related macular degeneration: results of a prospective and retrospective observational multicentre study.

The Swedish Lucentis Quality Registry is a 12-month, open-label, observational, prospective, and retrospective study of ranibizumab administration for wet AMD. Visual acuity (VA) was measured with Snellen or ETDRS chart in 370 patients (66.8% women; age range 46-93 years).

Characterization of new medium-chain alcohol dehydrogenases adds resolution to duplications of the class I/III and the sub-class I genes.

Four additional variants of alcohol and aldehyde dehydrogenases have been purified and functionally characterized, and their primary structures have been determined. The results allow conclusions about the structural and evolutionary relationships within the large family of MDR alcohol dehydrogenases from characterizations of the pigeon (Columba livia) and dogfish (Scyliorhinus canicula) major liver alcohol dehydrogenases. The pigeon enzyme turns out to be of class I type and the dogfish enzyme of class III type.

Identification of variant forms of the neuroendocrine peptide galanin.

Galanin is a neuroendocrine peptide widely distributed in the central and peripheral nervous systems and in endocrine tissues. Using radioimmunoassays, chromatographic separations, and tandem mass spectrometry, we have identified a series of five variant forms of galanin purified from porcine upper intestine. The modified variants include three beta-aspartyl-shifted forms, an oxidized form containing Trp monooxide, and an N-terminally truncated form.

Class III alcohol dehydrogenase: consistent pattern complemented with the mushroom enzyme.

Mushroom alcohol dehydrogenase (ADH) from Agaricus bisporus (common mushroom, champignon) was purified to apparent homogeneity. One set of ADH isozymes was found, with specificity against formaldehyde/glutathione. It had two highly similar subunits arranged in a three-member isozyme set of dimers with indistinguishable activity.

ORMDL proteins are a conserved new family of endoplasmic reticulum membrane proteins.

Background: Annotations of completely sequenced genomes reveal that nearly half of the genes identified are of unknown function, and that some belong to uncharacterized gene families. To help resolve such issues, information can be obtained from the comparative analysis of homologous genes in model organisms.

Results: While characterizing genes from the retinitis pigmentosa locus RP26 at 2q31-q33, we have identified a new gene, ORMDL1, that belongs to a novel gene family comprising three genes in humans (ORMDL1, ORMDL2 and ORMDL3), and homologs in yeast, microsporidia, plants, Drosophila, urochordates and vertebrates.

Ascidian and amphioxus Adh genes correlate functional and molecular features of the ADH family expansion during vertebrate evolution.

The alcohol dehydrogenase (ADH) family has evolved into at least eight ADH classes during vertebrate evolution. We have characterized three prevertebrate forms of the parent enzyme of this family, including one from an urochordate (Ciona intestinalis) and two from cephalochordates (Branchiostoma floridae and Branchiostoma lanceolatum). An evolutionary analysis of the family was performed gathering data from protein and gene structures, exon-intron distribution, and functional features through chordate lines.
