Expression cloning of a rat hepatic reduced glutathione transporter with canalicular characteristics

Using the Xenopus oocyte expression system, we have previously identified an approximately 4-kb fraction of mRNA from rat liver that expresses sulfobromophthalein-glutathione (BSP-GSH)-insensitive reduced glutathione (GSH) transport (Fernandez-Checa, J., J. R. Yi, C. Garcia-Ruiz, Z. Knezic, S. Tahara, and N. Kaplowitz. 1993. J. Biol. Chem. 268:2324-2328). Starting with a cDNA library constructed from this fraction, we have now isolated a single clone that expresses GSH transporter activity. The cDNA for the rat canalicular GSH transporter (RcGshT) is 4.05 kb with an open reading frame of 2,505 nucleotides encoding for a polypeptide of 835 amino acids (95,785 daltons). No identifiable homologies were found in searching various databases. An approximately 96-kD protein is generated in in vitro translation of cRNA for RcGshT. Northern blot analysis reveals a single 4-kb transcript in liver, kidney, intestine, lung, and brain. The abundance of mRNA for RcGshT in rat liver increased 3, 6, and 12 h after a single dose of phenobarbital. Insensitivity to BSP-GSH and induction by phenobarbital, unique characteristics of canalicular GSH secretion, suggest that RcGshT encodes for the canalicular GSH transporter.

Automated scoring of AFLPs using RawGeno v 2.0, a free R CRAN library.

Amplified Fragment Length Polymorphisms (AFLPs) are a cheap and efficient protocol for generating large sets of genetic markers. This technique has become increasingly used during the last decade in various fields of biology, including population genomics, phylogeography, and genome mapping. Here, we present RawGeno, an R library dedicated to the automated scoring of AFLPs (i.e., the coding of electropherogram signals into ready-to-use datasets). Our program includes a complete suite of tools for binning, editing, visualizing, and exporting results obtained from AFLP experiments. RawGeno can either be used with command lines and program analysis routines or through a user-friendly graphical user interface. We describe the whole RawGeno pipeline along with recommendations for (a) setting the analysis of electropherograms in combination with PeakScanner, a program freely distributed by Applied Biosystems; (b) performing quality checks; (c) defining bins and proceeding to scoring; (d) filtering nonoptimal bins; and (e) exporting results in different formats.

Animal Toxins: How is Complexity Represented in Databases?

Peptide toxins synthesized by venomous animals have been extensively studied in the last decades. To be useful to the scientific community, this knowledge has been stored, annotated and made easy to retrieve by several databases. The aim of this article is to present what type of information users can access from each database. ArachnoServer and ConoServer focus on spider toxins and cone snail toxins, respectively. UniProtKB, a generalist protein knowledgebase, has an animal toxin-dedicated annotation program that includes toxins from all venomous animals. Finally, the ATDB metadatabase compiles data and annotations from other databases and provides toxin ontology.

Library buildings : Selection of an architect ... A paper read before the Iowa Library Association at Grinnell, Iowa. October 30, 1902.

This leaflet, no. 7, by Grant C. Miller, of Patton & Miller Architects in Chicago, contains information on how to plan the erection of a new library building. It discusses how to select a librarian, architect, location and surroundings design and layout needed to best serve the library users.

A LIBRARY IN THE MAKING: Pioneer History of the Territorial and State Library of Iowa,October 1912

The discovery of early manuscript reports of Territorial and State Librarians, buried in the mass of old official papers transferred from the several departments of State to the new Department of Archives in the Historical Building, has suggested the propriety of completing as far as possible, the historical record of Iowa's State Library, "from the earliest period to the present time." After a thorough research through the papers on file in the Archives Department, the published Journals and departmental reports in the State Library and documents and private papers loaned me by Mr. Newton R. Parvin, librarian of the Iowa Masonic Library, Cedar Rapids. I am now able to present the following historical sketch, Supplemented by the hitherto unpublished papers referred to this filling a gap in the history of a State institution which from very small beginnings has grown to large proportions and has made for itself a firm place in the respect and esteem of every citizen of Iowa.

A process for mining science & technology documents databases, illustrated for the case of "knowledge discovery and data mining"

This paper presents a process of mining research & development abstract databases to profile current status and to project potential developments for target technologies, The process is called "technology opportunities analysis." This article steps through the process using a sample data set of abstracts from the INSPEC database on the topic o "knowledge discovery and data mining." The paper offers a set of specific indicators suitable for mining such databases to understand innovation prospects. In illustrating the uses of such indicators, it offers some insights into the status of knowledge discovery research*.
