Reduced Dosage of pos-1 Suppresses Mex Mutants and Reveals Complex Interactions Among CCCH Zinc-Finger Proteins During Caenorhabditis elegans Embryogenesis
Authors: Tenlen Jennifer R , Schisa Jennifer A , Diede Scott J , Page Barbara D
Published: October 2006

Cell fate specification in the early C. elegans embryo requires the activity of a family of proteins with CCCH zinc-finger motifs. Two members of the family, MEX-5 and MEX-6, are enriched in the anterior of the early embryo where they inhibit the accumulation of posterior proteins. Embryos from mex-5 single-mutant mothers are inviable due to the misexpression of SKN-1, a transcription factor that can specify mesoderm and endoderm. The aberrant expression of SKN-1 causes a loss of hypodermal and neuronal tissue and an excess of pharyngeal muscle, a Mex phenotype (muscle excess). POS-1, a third protein with CCCH motifs, is concentrated in the posterior of the embryo where it restricts the expression of at least one protein to the anterior. We discovered that reducing the dosage of pos-1(+) can suppress the Mex phenotype of mex-5(−) embryos and that POS-1 binds the 3′-UTR of mex-6. We propose that the suppression of the Mex phenotype by reducing pos-1(+) is due to decreased repression of mex-6 translation. Our detailed analyses of these protein functions reveal complex interactions among the CCCH finger proteins and suggest that their complementary expression patterns might be refined by antagonistic interactions among them.

Published: October 2006

Differential gene expression is the major mechanism underlying the development of specific body regions. Here we assessed the role of genes differentially expressed in the Drosophila wing imaginal disc, which gives rise to two distinct adult structures: the body wall and the wing. Reverse genetics was used to test the function of uncharacterized genes first identified in a microarray screen as having high levels of expression in the presumptive wing. Such genes could participate in elaborating the specific morphological characteristics of the wing. The activity of the genes was modulated using misexpression and RNAi-mediated silencing. Misexpression of eight of nine genes tested caused phenotypes. Of 12 genes tested, 10 showed effective silencing with RNAi transgenes, but only 3 of these had resulting phenotypes. The wing phenotypes resulting from RNAi suggest that CG8780 is involved in patterning the veins in the proximal region of the wing blade and that CG17278 and CG30069 are required for adhesion of wing surfaces. Venation and apposition of the wing surfaces are processes specific to wing development providing a correlation between the expression and function of these genes. The results show that a combination of expression profiling and tissue-specific gene silencing has the potential to identify new genes involved in wing development and hence to contribute to our understanding of this process. However, there are both technical and biological limitations to this approach, including the efficacy of RNAi and the role that gene redundancy may play in masking phenotypes.
Roles of PriA Protein and Double-Strand DNA Break Repair Functions in UV-Induced Restriction Alleviation inEscherichia coli
Authors: Ivančić-Baće Ivana , Vlašić Ignacija , Čogelja-Čajo Gordana , Brčić-Kostić Krunoslav , Salaj-Šmic Erika
Published: October 2006

It has been widely considered that DNA modification protects the chromosome of bacteria E. coli K-12 against their own restriction–modification systems. Chromosomal DNA is protected from degradation by methylation of target sequences. However, when unmethylated target sequences are generated in the host chromosome, the endonuclease activity of the EcoKI restriction-modification enzyme is inactivated by the ClpXP protease and DNA is protected. This process is known as restriction alleviation (RA) and it can be induced by UV irradiation (UV-induced RA). It has been proposed that chromosomal unmethylated target sequences, a signal for the cell to protect its own DNA, can be generated by homologous recombination during the repair of damaged DNA. In this study, we wanted to further investigate the genetic requirements for recombination proteins involved in the generation of unmethylated target sequences. For this purpose, we monitored the alleviation of EcoKI restriction by measuring the survival of unmodified λ in UV-irradiated cells. Our genetic analysis showed that UV-induced RA is dependent on the excision repair protein UvrA, the RecA-loading activity of the RecBCD enzyme, and the primosome assembly activity of the PriA helicase and is partially dependent on RecFOR proteins. On the basis of our results, we propose that unmethylated target sequences are generated at the D-loop by the strand exchange of two hemi-methylated duplex DNAs and subsequent initiation of DNA replication.

Published: October 2006

The objective of this study was to compare the patterns of T-cell differentiation from CD34+ human stem cells selected with different classes of antibody targeting the CD34 molecule. We compared signal-joint T-cell receptor excision circle (sjTREC) production in thymocytes selected with different classes of anti-CD34 antibody. Based on these results, we studied immune reconstitution in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice using human stem cells selected with the same antibodies that yielded variation in the thymocytes. Human CD34+ stem cells were immunomagnetically selected using the class II QBEnd antibody (prevalent in clinical graft engineering) and the class III 8G12 antibody (common in diagnostic tests). Engraftment and T-cell reconstitution were examined after transplantation. Thymocytes selected with the 8G12 class III antibody have a higher TREC production than those selected with the QBEnd class II antibody. Of mice transplanted with cells selected using the 8G12 antibody, 50% had sjTREC production, compared with 14% of mice transplanted with cells selected using the clinically common antibody QBEnd. 8G12 thymic progenitors are characterized by higher quality in thymic distribution and higher activity in T-cell differentiation. Using class III antibody targeting the CD34 molecule resulted in increased T-cell reconstitution in the NOD/SCID mouse. Use of a single antibody epitope targeting the CD34 molecule may lead to loss of cells that might provide richer T-cell reconstitution. Use of different or multiple epitopes, targeting of alternate stem cell markers, or use of cell-depletion strategies might prevent this loss.

A study of analysis errors caused by nitrite and free available chlorine during iodometric titration of total residual chlorine in wastewater
Authors: Dietz Edward A. , Cortellucci Remi , Williams Mary
Published: October 2006

Nitrite and free available chlorine (FAC) are reported to cause errors in total residual chlorine (TRC) measurements when following the Standard Methods back‐titration procedure with iodate titrant. Nitrite caused elevated TRC results when using either phenylarsine oxide or thiosulfate, which are the alternative reducing reagents specified in the procedure. FAC caused no error when phenylarsine oxide was used; however, TRC results were low when using thiosulfate. These errors are explained based on studies of the analysis chemistry, and method modifications are suggested for eliminating those errors. Thus, when using phenylarsine oxide, errors from nitrite were prevented by sulfamic acid, which was used to destroy nitrite. However, sulfamic acid could not be used with thiosulfate because the acidity of sulfamic acid induced a reaction between nitrite and thiosulfate. Errors from FAC are traced to an upset in the analysis reaction stoichiometry. With FAC present in samples, thiosulfate was not exclusively oxidized to tetrathionate. Instead, thiosulfate was partially converted to sulfate due to the strong oxidizing power of FAC. However, errors from FAC were eliminated by changing the order of reagent addition used in the analysis.
Effects of sample size (replicate number) on similarity measures in river benthic Aufwuchs community analysis
Authors: Cao Yang , Williams W. Peter , Bark Anthony W.
Published: October 2006

The effects of sample size (the number of replicates) on 11 similarity measures were investigated using a set of freshwater macroinvertebrate samples and a randomization procedure for resampling. Most of these indices were strongly affected by sample size. However, as sample size increased, species composition and relative abundance changed significantly and the real similarity between two replicate samples increased substantially. Responsiveness to sample size dictates the sensitivity of a similarity measure to community change. The relative independence of sample size of some similarity measures results from strongly overweighting abundant species. CY dissimilarity‐similarity measure showed the highest sensitivity, followed by Canberra metric.
Influence of Passive Humidification on Nasal Conditioning
Authors: Keck Tilman , Dürr Jochen , Leiacker Richard , Rozsasi Ajnacska , Rettinger Gerhard , Rother Timo
Published: October 2006

Background

Passive humidifiers (PH) have been beneficial to upper and lower airway humidity, especially in patients who are in a long-time ventilated intensive care unit. The goal of this pilot study was to provide nasal conditioning data and measure the benefit of a nasal PH to spontaneously breathing, conscious subjects.

Methods

Eleven healthy volunteers had to wear a PH for 1 hour, which was introduced into both nasal vestibules. The PH had a heat and moisture restoring body of polyurethane foam with an open-pore structure. Before and after application of the nasal PH, nasal conditioning was measured and nasal symptoms were assessed by the participants.

Results

Ten minutes after removal of the PH a significant increase was observed for the scores for nasal patency and nasal humidity.

Conclusion

We hypothesize that the nasal PH could provide a valuable contribution to the supportive therapy of diseases that accompany nasal mucosal dryness.

CONTINUUM: A Self‐Engineering Creature‐Culture
Authors: Ednie‐Brown Pia , Andrasek Alisa
Published: October 2006

An interdisciplinary design research collaborative led by Alisa Andrasek, CONTINUUM emerged from a series of design research seminars at Columbia University's graduate school of architecture. Working collaboratively with Robert Aish, Andresek's workshops explored the potential of the new Bentley Systems' GenerativeComponents design software, which at the time was in beta testing. CONTINUUM was formed to extend the possibilities of such collaborations and has expanded its network, occupying an interesting and unique territory of intersecting interests between academia, corporate practice and the companies that create design tools. Traditionally understood as antagonistic, commercial and progressive interests and intentions find common ground in their shared need for research into advanced design software that will enable the retooling of architectural practice. Here, Pia Ednie‐Brown, with illustrations by Alisa Andrasek, examines the unique ways in which CONTINUUM enfolds diverse professional and academic practices. Copyright © 2006 John Wiley & Sons, Ltd.
Language, Life, Code
Authors: R Galloway Alexander , Thacker Eugene
Published: October 2006

Software increasingly determines what can be designed, constructed and even how design occurs. Here, Alexander R Galloway and Eugene Thacker present a series of investigations with the collaborative Radical Software Group (RSG). Their practice examines the nature of software code as a form of language. Addressing theoretical issues regarding meaning and representation, they argue for thinking more abstractly and generatively about language, and propose a new, or liberated, computer language in which the representational determinations implicit to any software are geared towards innovation in communication and design. By rewriting the software that allows for the transmission and translation of knowledge across previously discrete fields of production, programming allows for new and productive cross‐pollination. Indeed, programming becomes a new site of design that enfolds disciplines not traditionally seen as part of the creative processes of innovation. Copyright © 2006 John Wiley & Sons, Ltd.
Critical Practice: Protocol for a Fused Technology
Authors: Sprecher Aaron , Ahrens Chandler , Neuman Eran
Published: October 2006

Software created for architecture often presumes a certain repertoire of design intents; software appropriated from other fields does not make such presumptions but introduces translation difficulties into material logics. Aaron Sprecher, Chandler Ahrens and Eran Neuman describe how their collaborative design group, Open Source Architecture (O‐S‐A), has worked with structural engineers and software developers to create a computational protocol based on a stochastic evolutionary topological optimisation algorithm. This procedure allows architectural designers to work with complex geometries previously limited to the expertise of engineering. In addition to taking the form of a distributed network spanning New York, Los Angeles and Tel Aviv, O‐S‐A opens the possibility for various disciplines (computer science, structural engineering, architectural design) to work with a fluidity and commonality not previously possible. Like the work of RSG (also featured in this issue), here design begins with the construction of a software environment in which a project can occur, and which merges previously distinct areas of expertise.

Published: October 2006

Small Design Firm, working with Ben Rubin of EAR Studio and artist Ann Hamilton, augments physical architectures with responsive and intelligent electronic interfaces. Recounting their recent collaborations on a series of projects, Small Design Firm's David Small and John Rothenberg discuss how such collaboration builds on generational continuities of technological innovation, and the ways in which their work has developed by recombining their individual interests and areas of expertise into a shared knowledge base through the process of developing specific designs. Physical space and projects thus become a site for the production of collective intelligence both as a design process and in the use of the end product. Copyright © 2006 John Wiley & Sons, Ltd.
Does Collaboration Work?
Authors: Kennon Kevin
Published: October 2006

Bringing together a number of design celebrities, among them Greg Lynn, UN Studio, Foreign Office Architects (FOA) and Kevin Kennon Architect, United Architects (UA) was established to create a collaborative proposal for the 2003 competition for a new World Trade Center. Invoking the name as well as the intentions of what started as a similar collaborative formation by established actors and film‐makers in the 1940s (United Artists) to challenge mainstream corporate power, UA attempted to offer more visionary alternatives to the expectations of typical mainstream architectural solutions. Kevin Kennon here presents an insider's perspective on the UA collaboration and employs his unique history, including his former partnership at Kohn Pedersen Fox (KPF) to raise important questions about collective design in terms of authorship, identity and practice. Central to his observations are the differences between the efficiency models of corporate teams and truly collaborative endeavours. Copyright © 2006 John Wiley & Sons, Ltd.
Strength in Numbers
Authors: Salomon David
Published: October 2006

David Salomon examines the history of the original World Trade Center (WTC) competition of 1962 and the more recent 2003 competition, finding interesting parallels in terms of how commercial and bureaucratic, as well as progressive, forces of innovation intersect over larger debates about control, power and questions of collaborative identity and practice within the city as a political machine, and which figure 9/11 in implicitly provocative ways. The 1962 competition featured another progressive architectural collaboration: Walter Gropius's The Architect's Collaborative (TAC). Not unlike the 2003 competition in which United Architects (UA) and other collaborative practices lost to the more stable, individual celebrity identity, TAC lost to Minoru Yamasaki. Salomon also argues that the organisational and structural qualities of UA's WTC proposal sought to embed collective operations of multiplicity rather than mere duplication of the previous WTC Twin Towers within the form of the design itself.

Computatonal Intelligence: The Grid as a Post‐Human Network
Authors: Morel Philippe
Published: October 2006

Research and design collaborative EZCT Architecture & Design Research has adopted grid computing to produce a series of furniture systems and other small‐scale prototypes using genetic algorithms in combination with automated fabrication technologies. Here, cofounder Philippe Morel relates this design practice to the broader technical and social implications of various grid‐computing projects, such as the online organisation Folding@Home, which utilises grid computing and distributed communities for the production and exchange of postindustrial knowledge. He argues that these ‘knowledge farms’ which create an ‘ambient factory’, are perhaps the ultimate form of social‐economic production, transforming not only the evolution of design but of the communities that produce and eventually consume its products.

Treatment 1: Notes from an Informal Discussion on Interinstitutional Design Research and Image Production
Authors: Bratton Benjamin , Diaz‐Alonso Hernan
Published: October 2006

Since 2003, Benjamin Bratton and Hernan Diaz‐Alonso have conducted a series of parallel theory seminars and design studios at SCI‐Arc (Southern California Institute of Architecture). These collaborations have addressed questions of collectivity at varying scales: personal (between two individuals, each with separate professional practices), institutional (between two disciplinary positions, one analytical and the other creative) and cultural (between what is inside and outside the architectural imaginary). The work featured in the article represents another primary mandate of their interinstitutional project: the transdisciplinary implications of design as a general form of practice as opposed to the historical definitions of ‘architecture’ or the architect.

When and why do we want to know? How experienced regret promotes post‐decision information search
Authors: Shani Yaniv , Zeelenberg Marcel
Published: October 2006

The effect of emotional and situational factors on the decision to seek out post‐decision information about un‐chosen alternative was examined in five experiments. Experiment 1 tested participants' willingness to find out the outcome of an un‐chosen investment that was likely to have a higher value than the chosen investment. It was found that participants were more willing to acquire information when they were responsible for the decision. Experiment 2 showed that responsibility affects information seeking, in particular when one suspects that a wrong decision was made. Experiments 3–5 examined the role of regret on information seeking. It was shown that regret about making the wrong investment (Experiment 3), forgetting to send in a lottery ticket (Experiment 4), and missing an opportunity to use a discount card after spending a month in Australia (Experiment 5), mediates the information‐seeking behavior. Experiment 5 also demonstrated that the experience of regret (and not its anticipation) influences post‐decision information seeking even when the information is of no future use.

Activity‐Stability Parameterization of Homogeneous Green Oxidation Catalysts

Published: October 2006

Small‐molecule synthetic homogeneous‐oxidation catalysts are normally poorly protected from self‐destruction under operating conditions. Achieving design control over both activity and half‐life is important not only in advancing the utility of oxidation catalysts, but also in minimizing hazards associated with their use and disposal. Iron(III)‐TAML (tetraamido‐macrocyclic ligand) oxidant catalysts rapidly activate H2O2 for numerous significant processes, exhibiting high and differing activity and varying half‐lives depending upon the TAML design. A general approach is presented that allows for the simultaneous determination of the second‐order rate constant for the oxidation of a targeted substrate by the active catalyst (kII) and the rate constant for the intramolecular self‐inactivation of the active catalyst (ki). The approach is valid if the formation of the active catalyst from its resting state and the primary oxidizing agent, measured by the second‐order rate constant kI, is fast and the catalyst concentration is very low, such that bimolecular inactivation pathways can be neglected. If the oxidation process is monitored spectrophotometrically and is set up to be incomplete, the kinetic trace can be analyzed by using the equation ln${\bigg(}$ln${{A{_{t}}\over A{_{\infty }}}}$${\bigg)}$=ln${\bigg(}$${{k{_{{\rm II}}}\over k{_{{\rm i}}}}}$[FeIII]tot${\bigg)}$−kit, from which kII and ki can be determined. Here, At and A∞ are absorbances at time t and at the end of reaction (t=∞), respectively, and [FeIII]tot is the total catalyst concentration. Several tools were applied to examine the validity of the approach by using a variety of different FeIII‐TAML catalysts, H2O2 and tBuOOH as oxidizing agents, and the dyes safranine O and orange II as target substrates. Learning how catalyst activities (kII) and catalyst half‐lives (ki) can be controlled by ligand design is an important step in creating green catalysts that will not persist in the environment after they have achieved their purpose.
