Abstract
Sala, A., O'Neill, F. G., Buglioni, G., Lucchetti, A., Palumbo, V., and Fryer, R. J. 2007. Experimental method for quantifying resistance to the opening of netting panels. – ICES Journal of Marine Science, 64: 1573–1578. In recent years, the tendency in some sectors of the fishing industry has been to use thicker and stiffer twines in the manufacture of netting material. This increases the mesh's resistance to opening and, consequently, reduces the selective performance of fishing gears. The main characteristic of netting twine contributing to mesh resistance to opening is flexural rigidity (EI). We present a methodology for quantifying mesh resistance to opening through the use of a prototype called the resistance to opening and deflection meter (ROD-m). It incorporates four tension load cells and four stepping motors that are driven by four ministep bipolar chopper drives. Small panels of netting (3 × 3 meshes) can be mounted on ROD-m, which can measure the forces acting on the netting and the position of the knots. Estimates of the flexural rigidity of the netting twine can be made from these data. We present the results of the analysis of Mediterranean polyamide netting, and standard and Brezline polyethylene (PE) netting from the North Sea. In all netting, regardless of the material used, EI increases with increasing linear density. Furthermore, Brezline is much stiffer than standard green PE, although they are equally thick.

The aim of this clinical study was to determine whether there is a relationship between total serum testosterone, free testosterone, FSH (Follicle-Stimulating Hormone), LH (Luteinizing Hormone) and serum prostate specific antigen (PSA) levels. We postulated that such a correlation existed then the use of hormone specific reference ranges might enhance the usefullness of PSA concentrations <2.5 ng/mL as a marker for prostate cancer.Prior to digital rectal examination, serum was obtained from all patients between 8.30-10:00 AM for hormone and PSA concentrations. The study was performed on 210 male patients >40 years of age visiting our urology outpatient clinics. PSA was correlated to age (r = 0.23, p = 0.019), but there none between serum testosterone and age. No significant correlation was noted between testosterone or free testosterone and serum PSA levels, and none between serum FSH or LH and PSA. In age specific reference groups (41-49; 50-59; 60-69 years), we found no significant correlation between PSA and hormone concentrations.In this population of eugonadal men with serum PSA values less than 2.5 ng/ml, serum androgens and pituitary hormones do not appear to correlate with serum PSA.

AbstractYoung meristematic plant cells contain a large number of small vacuoles, while the largest part of the vacuome in mature cells is composed by a large central vacuole, occupying 80% to 90% of the cell volume. Thus far, only a limited number of vacuolar membrane proteins have been identified and characterized. The proteomic approach is a powerful tool to identify new vacuolar membrane proteins. To analyze vacuoles from growing tissues we isolated vacuoles from cauliflower (Brassica oleracea) buds, which are constituted by a large amount of small cells but also contain cells in expansion as well as fully expanded cells. Here we show that using purified cauliflower vacuoles and different extraction procedures such as saline, NaOH, acetone, and chloroform/methanol and analyzing the data against the Arabidopsis (Arabidopsis thaliana) database 102 cauliflower integral proteins and 214 peripheral proteins could be identified. The vacuolar pyrophosphatase was the most prominent protein. From the 102 identified proteins 45 proteins were already described. Nine of these, corresponding to 46% of peptides detected, are known vacuolar proteins. We identified 57 proteins (55.9%) containing at least one membrane spanning domain with unknown subcellular localization. A comparison of the newly identified proteins with expression profiles from in silico data revealed that most of them are highly expressed in young, developing tissues. To verify whether the newly identified proteins were indeed localized in the vacuole we constructed and expressed green fluorescence protein fusion proteins for five putative vacuolar membrane proteins exhibiting three to 11 transmembrane domains. Four of them, a putative organic cation transporter, a nodulin N21 family protein, a membrane protein of unknown function, and a senescence related membrane protein were localized in the vacuolar membrane, while a white-brown ATP-binding cassette transporter homolog was shown to reside in the plasma membrane. These results demonstrate that proteomic analysis of highly purified vacuoles from specific tissues allows the identification of new vacuolar proteins and provides an additional view of tonoplastic proteins.
Gibberellin Regulation of Fruit Set and Growth in Tomato

Published: July 2007

AbstractThe role of gibberellins (GAs) in tomato (Solanum lycopersicum) fruit development was investigated. Two different inhibitors of GA biosynthesis (LAB 198999 and paclobutrazol) decreased fruit growth and fruit set, an effect reversed by GA3 application. LAB 198999 reduced GA1 and GA8 content, but increased that of their precursors GA53, GA44, GA19, and GA20 in pollinated fruits. This supports the hypothesis that GA1 is the active GA for tomato fruit growth. Unpollinated ovaries developed parthenocarpically in response to GA3 &gt; GA1 = GA4 &gt; GA20, but not to GA19, suggesting that GA 20-oxidase activity was limiting in unpollinated ovaries. This was confirmed by analyzing the effect of pollination on transcript levels of SlCPS, SlGA20ox1, -2, and -3, and SlGA3ox1 and -2, encoding enzymes of GA biosynthesis. Pollination increased transcript content of SlGA20ox1, -2, and -3, and SlCPS, but not of SlGA3ox1 and -2. To investigate whether pollination also altered GA inactivation, full-length cDNA clones of genes encoding enzymes catalyzing GA 2-oxidases (SlGA2ox1, -2, -3, -4, and -5) were isolated and characterized. Transcript levels of these genes did not decrease early after pollination (5-d-old fruits), but transcript content reduction of all of them, mainly of SlGA2ox2, was found later (from 10 d after anthesis). We conclude that pollination mediates fruit set by activating GA biosynthesis mainly through up-regulation of GA20ox. Finally, the phylogenetic reconstruction of the GA2ox family clearly showed the existence of three gene subfamilies, and the phylogenetic position of SlGA2ox1, -2, -3, -4, and -5 was established.
AtNUDT7, a Negative Regulator of Basal Immunity in Arabidopsis, Modulates Two Distinct Defense Response Pathways and Is Involved in Maintaining Redox Homeostasis

Published: July 2007

AbstractPlants have evolved complicated regulatory systems to control immune responses. Both positive and negative signaling pathways interplay to coordinate development of a resistance response with the appropriate amplitude and duration. AtNUDT7, a Nudix domain-containing protein in Arabidopsis (Arabidopsis thaliana) that hydrolyzes nucleotide derivatives, was found to be a negative regulator of the basal defense response, and its loss-of-function mutation results in enhanced resistance to infection by Pseudomonas syringae. The nudt7 mutation does not cause a strong constitutive disease resistance phenotype, but it leads to a heightened defense response, including accelerated activation of defense-related genes that can be triggered by pathogenic and nonpathogenic microorganisms. The nudt7 mutation enhances two distinct defense response pathways: one independent of and the other dependent on NPR1 and salicylic acid accumulation. In vitro enzymatic assays revealed that ADP-ribose and NADH are preferred substrates of NUDT7, and the hydrolysis activity of NUDT7 is essential for its biological function and is sensitive to inhibition by Ca2+. Further analyses indicate that ADP-ribose is not likely the physiological substrate of NUDT7. However, the nudt7 mutation leads to perturbation of cellular redox homeostasis and a higher level of NADH in pathogen-challenged leaves. The study suggests that the alteration in cellular antioxidant status caused by the nudt7 mutation primes the cells for the amplified defense response and NUDT7 functions to modulate the defense response to prevent excessive stimulation.
Light-Independent Phytochrome Signaling Mediated by Dominant GAF Domain Tyrosine Mutants ofArabidopsisPhytochromes in Transgenic Plants
Authors: Su Yi-shin , Lagarias J. Clark 
Published: July 2007

AbstractThe photoreversibility of plant phytochromes enables continuous surveillance of the ambient light environment. Through expression of profluorescent, photoinsensitive Tyr-to-His mutant alleles of Arabidopsis thaliana phytochrome B (PHYBY276H) and Arabidopsis phytochrome A (PHYAY242H) in transgenic Arabidopsis plants, we demonstrate that photoconversion is not a prerequisite for phytochrome signaling. PHYBY276H-expressing plants exhibit chromophore-dependent constitutive photomorphogenesis, light-independent phyBY276H nuclear localization, constitutive activation of genes normally repressed in darkness, and light-insensitive seed germination. Fluence rate analyses of transgenic plants expressing PHYBY276H, PHYAY242H, and other YGAF mutant alleles of PHYB demonstrate that a range of altered light-signaling activities are associated with mutation of this residue. We conclude that the universally conserved GAF domain Tyr residue, with which the bilin chromophore is intimately associated, performs a critical role in coupling light perception to signal transduction by plant phytochromes.

Making choices: research paradigms and information management
Authors: Burke M.E. 
Published: July 2007

PurposeThe purpose of this paper is to examine a variety of research approaches which information managers may find useful to meet the needs of working in the networked, digitized age.Design/methodology/approachThis is achieved by a discussion of the research paradigms inherent within both information theory and social theory.FindingsThe findings work towards a final justification for an interpretist approach as the most appropriate context in which to work, in order to meet the emerging trends and current challenges of information technology management.Practical implicationsThe central theme of this paper is that research which deals primarily with people and information in a world of change, competition, and fluid communications technology should take into account and allow for an understanding of human behaviour. This understanding helps to highlight different contexts, backgrounds, and cultures and therefore provides assistance in making appropriate choices concerning research paradigms and information management, which in turn will ensure thoughtful methodology and justifiable research results.Originality/valueThis paper examined questions regarding the choices of research paradigms and the practical application of philosophy to the life of professional information managers.

Authors: Morgan Rachael 
Published: July 2007

PurposeThe purpose of this paper is to demonstrate the issues surrounding the implementation of an online reading list system at the University of Glamorgan.Design/methodology/approachThe paper reports on an implementation project, using Talis List, which took place between November 2005 and March 2006.FindingsThe project itself was a success, with the target number of reading lists made available being exceeded. As with any new system, the development of the processes involved in its day‐to‐day running can be unpredictable. Workflows did not develop as anticipated; the ways in which reading lists were collected from academics varied, as did the styles of the lists themselves. Some issues were encountered around linking to electronic resources and embedding the system into the university's virtual learning environment (VLE).Originality/valueThis paper will be of value to those interested in the development and use of online reading lists.

Authors: McKinzie Steve 
Published: July 2007

PurposeThe purpose of this paper is to provide an introduction to four articles from Reference Services Review focusing on the theme of library/IT mergers. It aims to place the articles that follow in their larger historical context and draw conclusions about the success or lack of success of such mergers in general.Design/methodology/approachThe paper frames the four articles that follow, explaining their approach to library/IT mergers and their place in the ongoing discussion of the service effectiveness of such converged organizations.FindingsThe paper suggests that library/IT service mergers may be analogous to management's or labor's decision to unionize.Practical implicationsThe success of academic libraries and IT services has more to do with the quality of leadership and professional commitment to service than it does with the question of whether these two academic units should merge.Originality/valueThe paper provides an introduction to the special issue on library and IT mergers.
The perception of effectiveness of merged information services organizations
Authors: Stemmer John K. 
Published: July 2007

PurposeThe purpose of this paper is to assess the perceptions of chief information officers and academic deans with respect to the effectiveness of merged information services organizations (MISOs) at liberal arts colleges.Design/methodology/approachThis study is descriptive exploratory survey research. A survey of chief information officers (CIOs) and academic deans of liberal arts colleges with merged information services organizations was undertaken. In addition to a general assessment of the MISO, a taxonomy of expected benefits was developed from the literature. Respondents provided information on both the general effectiveness of the MISO and its delivery of the expected benefits. Both quantitative and qualitative data were collected.FindingsThe paper finds that both CIOs and academic deans had a favorable impression of the MISO and believed it was effective in providing support and delivering expected benefits. Concerns were raised that the MISO organization requires staff development time and can contribute to a loss of focus among constituent units.Research limitations/implicationsThe study is limited to Carnegie bachelor's level institutions with a MISO.Practical implicationsMISOs are effective in providing support and the expected benefits. Institutions implementing or considering the MISO model should be aware of possible problem areas (staff development and loss of unit focus) and plan to address them appropriately.Originality/valueThe study identified areas of concern among both CIOs and deans with the implementation of a MISO. Information services units' leadership as well as institutional administration should consider these findings when considering or implementing a MISO.

Authors: Mary Walters Carolyn , Van Gordon Elizabeth Ann 
Published: July 2007

PurposeIncreasingly academic libraries are partnering with other campus units to improve efficiency and to better serve students and faculty. This paper aims to focus on the importance of developing a memorandum of understanding (MOU) to foster a relationship between an academic library and IT unit. It seeks to identify what the MOU should include, pitfalls to be avoided, and lessons learned. It also proposes demonstrating how the MOU has been used as a model for other alliances and how, because of the MOU, a partnership has flourished.Design/methodology/approachThis paper will outline the steps taken that led to the successful MOU created by the Indiana University Bloomington (IUB) Libraries and University Information Technology Services (UITS.)FindingsThe paper finds that a well‐crafted MOU that allows for flexibility in ongoing decision making by service stakeholders permits partnerships to evolve and mature and creates the avenue for continued success and innovation.Practical implicationsThis paper describes the execution and ongoing evolution of a successful partnership based on a MOU and commitment by the IUB Libraries and the central technology organization, UITS.Originality/valueLibraries interested in entering into or strengthening partnerships with IT or other campus organizations can use the Indiana University experience and MOU as a model.
