Improving oncolytic adenoviral therapies for gastrointestinal cancers and tumor initiating cells

Although the treatment of most cancers has improved steadily, only few metastatic solid tumors can be cured. Despite responses, refractory clones often emerge and the disease becomes refractory to available treatment modalities. Furthermore, resistance factors are shared between different treatment regimens and therefore loss of response typically occurs rapidly, and there is a tendency for cross-resistance between agents. Therefore, new agents with novel mechanisms of action and lacking cross-resistance to currently available approaches are needed. Modified oncolytic adenoviruses, featuring cancer-celective cell lysis and spread, constitute an interesting drug platform towards the goals of tumor specificity and the implementation of potent multimodal treatment regimens. In this work, we demonstrate the applicability of capsid-modified, transcriptionally targeted oncolytic adenoviruses in targeting gastric, pancreatic and breast cancer. A variety of capsid modified adenoviruses were tested for transductional specificity first in gastric and pancreatic cancer cells and patient tissues and then in mice. Then, oncolytic viruses featuring the same capsid modifications were tested to confirm that successful transductional targeting translates into enhanced oncolytic potential. Capsid modified oncolytic viruses also prolonged the survival of tumor bearing orthotopic models of gastric and pancreatic cancer. Taken together, oncolytic adenoviral gene therapy could be a potent drug for gastric and pancreatic cancer, and its specificity, potency and safety can be modulated by means of capsid modification. We also characterized a new intraperitoneal virus delivery method in benefit for the persistence of gene delivery to intraperitoneal gastric and pancreatic cancer tumors. With a silica implant a steady and sustained virus release to the vicinity of the tumor improved the survival of the orthotopic tumor bearing mice. Furthermore, silica gel-based virus delivery lowered the toxicity mediating proimflammatory cytokine response and production of total and anti-adenovirus neutralizing antibodies (NAbs). On the other hand, silica shielded the virus against pre-excisting NAbs, resulting in a more favourable biodistribution in the preimmunized mice. The silica implant might therefore be of interest in treating intraperitoneally disseminated disease. Cancer stem cells are thought to be resistant to conventional cancer drugs and might play an important role in cancer relapse and the formation of metastasis. Therefore, we examined if transcriptionally modified oncolytic adenoviruses are able to kill these cells. Complete eradication of CD44+CD24-/low putative breast cancer stem cells was seen in vitro, and significant antitumor activity was detected in CD44+CD24-/low –derived tumor bearing mice. Thus, genetically engineered oncolytic adenoviruses have potential in destroying cancer initiating cells, which may have relevance for the elimination of cancer stem cells in humans.

Corymbia leaf oils, latitude, hybrids and herbivory: a test using common-garden field trials

Foliar oils, particularly monoterpenes, can influence the susceptibility of plants to herbivory. In plants, including eucalypts, monoterpenes are often associated with plant defence. A recent analysis revealed an increase in foliar oil content with increasing latitudinal endemism, and we tested this pattern using three eucalypt taxa comprising a latitudinal replacement cline. We also examined the relative concentrations of two monoterpenes (alpha-pinene and 1,8-cineole), for which meta-analyses also showed latitudinal variation, using hybrids of these three taxa with Corymbia torelliana. These, and pure C. torelliana, were then assessed in common-garden field plots for the abundance and distribution of herbivory by four distinct herbivore taxa. Differing feeding strategies among these herbivores allowed us to test hypotheses regarding heritability of susceptibility and relationships to alpha-pinene and 1,8-cineole. We found no support for an increase in foliar oil content with increasing latitude, nor did our analysis support predictions for consistent variation in alpha-pinene and 1,8-cineole contents with latitude. However, herbivore species showed differential responses to different taxa and monoterpene contents. For example, eriophyid mites, the most monophagous of our censused herbivores, avoided the pure species, but fed on hybrid taxa, supporting hypotheses on hybrid susceptibility. The most polyphagous herbivore (leaf blister sawfly Phylacteophaga froggatti) showed no evidence of response to plant secondary metabolites, while the distribution and abundance patterns of Paropsis atomaria showed some relationship to monoterpene yields.

Quantitative trait loci detection and benefits from marker-assisted selection in dairy cattle

Knowing the chromosomal areas or actual genes affecting the traits under selection would add more information to be used in the selection decisions which would potentially lead to higher genetic response. The first objective of this study was to map quantitative trait loci (QTL) affecting economically important traits in the Finnish Ayrshire population. The second objective was to investigate the effects of using QTL information in marker-assisted selection (MAS) on the genetic response and the linkage disequilibrium between the different parts of the genome. Whole genome scans were carried out on a grand-daughter design with 12 half-sib families and a total of 493 sons. Twelve different traits were studied: milk yield, protein yield, protein content, fat yield, fat content, somatic cell score (SCS), mastitis treatments, other veterinary treatments, days open, fertility treatments, non-return rate, and calf mortality. The average spacing of the typed markers was 20 cM with 2 to 14 markers per chromosome. Associations between markers and traits were analyzed with multiple marker regression. Significance was determined by permutation and genome-wise P-values obtained by Bonferroni correction. The benefits from MAS were investigated by simulation: a conventional progeny testing scheme was compared to a scheme where QTL information was used within families to select among full-sibs in the male path. Two QTL on different chromosomes were modelled. The effects of different starting frequencies of the favourable alleles and different size of the QTL effects were evaluated. A large number of QTL, 48 in total, were detected at 5% or higher chromosome-wise significance. QTL for milk production were found on 8 chromosomes, for SCS on 6, for mastitis treatments on 1, for other veterinary treatments on 5, for days open on 7, for fertility treatments on 7, for calf mortality on 6, and for non-return rate on 2 chromosomes. In the simulation study the total genetic response was faster with MAS than with conventional selection and the advantage of MAS persisted over the studied generations. The rate of response and the difference between the selection schemes reflected clearly the changes in allele frequencies of the favourable QTL. The disequilibrium between the polygenes and QTL was always negative and it was larger with larger QTL size. The disequilibrium between the two QTL was larger with QTL of large effect and it was somewhat larger with MAS for scenarios with starting frequencies below 0.5 for QTL of moderate size and below 0.3 for large QTL. In conclusion, several QTL affecting economically important traits of dairy cattle were detected. Further studies are needed to verify these QTL, check their presence in the present breeding population, look for pleiotropy and fine map the most interesting QTL regions. The results of the simulation studies show that using MAS together with embryo transfer to pre-select young bulls within families is a useful approach to increase the genetic merit of the AI-bulls compared to conventional selection.

Phosphine Resistance in the Rust Red Flour Beetle, Tribolium castaneum (Coleoptera: Tenebrionidae): Inheritance, Gene Interactions and Fitness Costs

The recent emergence of heritable high level resistance to phosphine in stored grain pests is a serious concern among major grain growing countries around the world. Here we describe the genetics of phosphine resistance in the rust red flour beetle Tribolium castaneum (Herbst), a pest of stored grain as well as a genetic model organism. We investigated three field collected strains of T. castaneum viz., susceptible (QTC4), weakly resistant (QTC1012) and strongly resistant (QTC931) to phosphine. The dose-mortality responses of their test- and inter-cross progeny revealed that most resistance was conferred by a single major resistance gene in the weakly (3.2x) resistant strain. This gene was also found in the strongly resistant (431x) strain, together with a second major resistance gene and additional minor factors. The second major gene by itself confers only 12-206x resistance, suggesting that a strong synergistic epistatic interaction between the genes is responsible for the high level of resistance (431x) observed in the strongly resistant strain. Phosphine resistance is not sex linked and is inherited as an incompletely recessive, autosomal trait. The analysis of the phenotypic fitness response of a population derived from a single pair inter-strain cross between the susceptible and strongly resistant strains indicated the changes in the level of response in the strong resistance phenotype; however this effect was not consistent and apparently masked by the genetic background of the weakly resistant strain. The results from this work will inform phosphine resistance management strategies and provide a basis for the identification of the resistance genes.

Kansankirkko, uskonnonvapaus ja valtio : Suomen evankelis-luterilaisen kirkon kirkolliskokouksen tulkinta uskonnonvapaudesta 1963-2003

A national church, freedom of religion, and the state The interpretation of freedom of religion formulated by the Synod of the Evangelical Lutheran Church of Finland in reference to the relationship between the Church and the state from 1963 to 2003 This paper discusses the interpretation of freedom of religion formulated by the Synod of the Evangelical Lutheran Church of Finland during the years 1963-2003. The effect of these formulations and decisions made by the Synod on the relationship between the Church and the state is also discussed as the relationship has been a central issue in the debate about freedom of religion in Finland. Active co-operation with the state caused a dispute in the Church during this period. Another cause for concern for the Synod, a strong defender of the national church, was the weakening position of the Church in a society undergoing many changes. As the Synod of 1963 discussed the status of the Church, the Church began to reflect upon its identity as a national church, and to evaluate freedom of religion in the country, as well as the relationship between the Church and the state. Some of the radicals of the 1960s and 1970s presented the Church as an obstacle to freedom of religion. The Synod was keen to emphasize that, in accordance with international agreements on human rights, freedom of religion means the freedom to have and follow a religion, and also that freedom of religion was a right of the majority in Finnish society. As an active guardian of the rights of its members, the Synod defended such issues as the teaching of religion in schools. Throughout the dispute, the Church focused on its right to act freely and, according to its identity, to express spirituality in the society. At the end of the 1960s, several efforts to reform the law on the freedom of religion and the relationship between the Church and the state gained favour in the Synod. These formulations of the Church were the basis for the work of a parliamentary committee in the 1970s, but no significant changes resulted. Instead, freedom of religion in Finland was judged to be fairly good. The committee paper did, however, lead to preparations for greater independence of the Church. The Synod at the time chose to react to the changes presented to it, but it was not before the 1990s that the Synod became an active force of reform in these matters. Though the Synod, particularly from the 1970s onwards, began clearly to favour the improvement of the position of other religious communities in Finland, it felt it had reason to be cautious as each church and religious community had the freedom to decide individually its relationship with the state. Any changes that would have weakened the position of the Church in Finnish society were met with disapproval in the Synod. Even though some theological concerns regarding the national identity of the Church were raised, the Synod emphasized issues of church policy. Keen to preserve and protect its legal status in society, the Synod judged that this status supported the freedom of action enjoyed by the Church as well as the freedom of religion.

Gendering and racialising self-determination: Indigenous women and patriarchal whiteness

Indigenous peoples have the right of self-determination, in accordance with international law by virtue of which tehy may freely determine their political status and institutions and freely pursue their economic, social and cultural development. an integral part of this is the right to autonomy and self-government. The essential feature of racism is not hostility or misperception, but rather the defense [sic] of a system from which advantage is derived on the basis of race. The manner in which the defense [sic] is articulated - either as hostility or subtlety - is not nearly as important as the fact that it insures the continuation of a privileged relationship.

Essays on corporate governance, stakeholders, and restructuring

This dissertation consists of an introductory section and three theoretical essays analyzing the interaction of corporate governance and restructuring. The essays adopt an incomplete contracts approach and analyze the role of different institutional designs to facilitate the alignment of the objectives of shareholders and management (or employees) over the magnitude of corporate restructuring. The first essay analyzes how a firm's choice of production technology affects the employees' human capital investment. In the essay, the owners of the firm can choose between a specific and a general technology that both require a costly human capital investment by the employees. The specific technology is initially superior in using the human capital of employees but, in contrast to the general technology, it is not compatible with future innovations. As a result, anticipated changes in the specific technology diminish the ex ante incentives of the employees to invest in human capital unless the shareholders grant the employees specific governance mechanisms (a right of veto, severance pay) so as to protect their investments. The results of the first essay indicate that the level of protection that the shareholders are willing to offer falls short of the socially desirable one. Furthermore, when restructuring opportunities become more abundant, it becomes more attractive both socially and from the viewpoint of the shareholders to initially adopt the general technology. The second essay analyzes how the allocation of authority within the firm interacts with the owners' choice of business strategy when the ability of the owners to monitor the project proposals of the management is biased in favor of the status quo strategy. The essay shows that a bias in the monitoring ability will affect not only the allocation of authority within the firm but also the choice of business strategy. Especially, when delegation has positive managerial incentive effects, delegation turns out to be more attractive under the new business strategy because the improved managerial incentives are a way for the owners to compensate their own reduced information gathering ability. This effect, however, simultaneously makes the owners hesitant to switch the strategy since it would involve a more frequent loss of control over the project choice. Consequently, the owners' lack of knowledge of the new business strategy may lead to a suboptimal choice of strategy. The third essay analyzes the implications of CEO succession process for the ideal board structure. In this essay, the presence of the departing CEO on the board facilitates the ability of the board to find a matching successor and to counsel him. However, the ex-CEO's presence may simultaneously also weaken the ability of the board to restructure since the predecessor may use the opportunity to distort the successor's project choice. The results of the essay suggest that the extent of restructuring gains, the firm's ability to hire good outside directors and the importance of board's advisory role affect at which point and for how long the shareholders may want to nominate the predecessor to the board.

A Nonmoving-Part Fluidic Display Using Photoelastic Effect

Digital fluidic and pneumatic systems incorporate displays for the presentation of information to the operator. Displays reported so far for such systems use moving pistons, tapes, and other mechanisms leading to lower reliability. This paper describes a nonmoving part fluidic display employing the photoelastic effect. The display is pressure actuated and has a long life. When fabricated from compatible materials, this device can withstand hostile environments like nuclear radiation, vibrations, etc. The display is compact, economical and is virtually maintenance free. The display unit has been tested in the laboratory for reliability and speed of response.

Polypyrrole based amperometric glucose biosensors

Biosensors have gained immense acceptance in the field of medical diagnostics, besides environmental, food safety and biodefence applications due to its attributes of real-time and rapid response. This synergistic combination of biotechnology and microelectronics comprises a biological recognition element coupled with a compatible transducer device. Diabetes is a disease of major concern since the ratio of world population suffering from it is increasing at an alarming rate and therefore the need for development of accurate and stable glucose biosensors is evident. There are many commercial glucose biosensors available yet some limitations need attention. This review presents a detailed account of the polypyrrole based amperometric glucose biosensors. The polymer polypyrrole is used extensively as a matrix for immobilization of glucose oxidase enzyme owing to its favourable features such as stability under ambient conditions, conductivity that allows it to be used as an electron relay, ability to be polymerized under neutral and aqueous mild conditions, and more. The simple one-step electrodeposition on the electrode surface allows easy entrapment of the enzyme. The review is structured into three categories (a) the first-stage biosensors: which report the studies from the inception of use of polypyrrole in glucose biosensors during which time the role of the polymer and the use of mediators was established. This period saw extensive work by two separate groups of Schuhmann and Koopal who contributed a great deal in understanding the electron transfer pathways in polypyrrole based glucose biosensors, (b) the second-stage biosensors: which highlight the shift of polypyrrole from a conventional matrix to composite matrices with extensive use of mediators focused at improving the selectivity of response, and (c) third-stage biosensors: the remarkable properties of nanoparticles and carbon nanotubes and their outstanding ability to mediate electrontransfers have seen their indispensable use in conjugation with polypyrrole for development of glucose biosensors with improved sensitivity and stability characteristics which is accounted in the review, which thus traces the evolution of polypyrrole from a conventional matrix, to composites and thence to the form of nanotube arrays, with the objective of addressing the vital issue of diabetes management through the development of stable and reliable glucose biosensors.

A Kalman filter based strategy for linear structural system identification based on multiple static and dynamic test data

The problem of identification of stiffness, mass and damping properties of linear structural systems, based on multiple sets of measurement data originating from static and dynamic tests is considered. A strategy, within the framework of Kalman filter based dynamic state estimation, is proposed to tackle this problem. The static tests consists of measurement of response of the structure to slowly moving loads, and to static loads whose magnitude are varied incrementally; the dynamic tests involve measurement of a few elements of the frequency response function (FRF) matrix. These measurements are taken to be contaminated by additive Gaussian noise. An artificial independent variable τ, that simultaneously parameterizes the point of application of the moving load, the magnitude of the incrementally varied static load and the driving frequency in the FRFs, is introduced. The state vector is taken to consist of system parameters to be identified. The fact that these parameters are independent of the variable τ is taken to constitute the set of ‘process’ equations. The measurement equations are derived based on the mechanics of the problem and, quantities, such as displacements and/or strains, are taken to be measured. A recursive algorithm that employs a linearization strategy based on Neumann’s expansion of structural static and dynamic stiffness matrices, and, which provides posterior estimates of the mean and covariance of the unknown system parameters, is developed. The satisfactory performance of the proposed approach is illustrated by considering the problem of the identification of the dynamic properties of an inhomogeneous beam and the axial rigidities of members of a truss structure.

Biological mechanisms behind clozapine-induced agranulocytosis

Clozapine is the most effective drug in treating therapy-resistant schizophrenia and may even be superior to all other antipsychotics. However, its use is limited by a high incidence (approximately 0.8%) of a severe hematological side effect, agranulocytosis. The exact molecular mechanism(s) of clozapine-induced agranulocytosis is still unknown. We investigated the mechanisms behind responsiveness to clozapine therapy and the risk of developing agranulocytosis by performing an HLA (human leukocyte antigens) association study in patients with schizophrenia. The first group comprised patients defined by responsiveness to first-generation antipsychotics (FGAs) (n= 19). The second group was defined by a lack of response to FGAs but responsiveness to clozapine (n=19). The third group of patients had a history of clozapine-induced granulocytopenia or agranulocytosis (n=26). Finnish healthy blood donors served as controls (n= 120). We found a significantly increased frequency of HLA-A1 among patients who were refractory to FGAs but responsive to clozapine. We also found that the frequency of HLA-A1 was low in patients with clozapine-induced neutropenia or agranulocytosis. These results suggest that HLA-A1 may predict a good therapeutic outcome and a low risk of agranulocytosis and therefore HLA typing may aid in the selection of patients for clozapine therapy. Furthermore, in a subgroup of schizophrenia, HLA-A1 may be in linkage disequilibrium with some vulnerability genes in the MHC (major histocompatibility complex) region on chromosome 6. These genes could be involved in antipsychotic drug response and clozapine-induced agranulocytosis. In addition, we investigated the effect of clozapine on gene expression in granulocytes by performing a microarray analysis on blood leukocytes of 8 schizophrenic patients who had started clozapine therapy for the first time. We identified an altered expression in 4 genes implicated in the maturation or apoptosis of granulocytes: MPO (myeloperoxidase precursor), MNDA (myeloid cell nuclear differentiation antigen), FLT3LG (Fms-related tyrosine kinase 3 ligand) and ITGAL (antigen CD11A, lymphocyte function-associated antigen 1). The altered expression of these genes following clozapine administration may suggest their involvement in clozapine-induced agranulocytosis. Finally, we investigated whether or not normal human bone marrow mesenchymal stromal cells (MSC) are sensitive to clozapine. We treated cultures of human MSCs and human skin fibroblasts with 10 µM of unmodified clozapine and with clozapine bioactivated by oxidation. We found that, independent of bioactivation, clozapine was cytotoxic to MSCs in primary culture, whereas clozapine at the same concentration stimulated the growth of human fibroblasts. This suggests that direct cytotoxicity to MSCs is one possible mechanism by which clozapine induces agranulocytosis.

Organisational Responses to Workplace Harassment: An Exploratory Study

Purpose – The aim of this paper is to explore what kind of measures personnel managers have taken to intervene in workplace harassment and to explore how organisational characteristics and the characteristics of the personnel manager affect the choice of response strategies. Design/methodology/approach – The study was exploratory and used a survey design. A web-based questionnaire was sent to the personnel managers of all Finnish municipalities and data on organisational responses and organisational characteristics were collected. Findings – The study showed that the organisations surveyed relied heavily on reconciliatory measures for responding to workplace harassment and that punitive measures were seldom used. Findings indicated that personnel manager gender, size of municipality, use of “sophisticated” human resource management practices and having provided information and training to increase awareness about harassment all influence the organisational responses chosen. Research limitations/implications – Only the effects of organisational and personnel manager characteristics on organisational responses were analysed. Future studies need to include perpetrator characteristics and harassment severity. Practical implications – The study informs both practitioners and policy makers about the measures that have been taken and that can be taken in order to stop harassment. It also questions the effectiveness of written anti-harassment policies for influencing organisational responses to harassment and draws attention to the role of gendered perceptions of harassment for choice of response strategy. Originality/value – This paper fills a gap in harassment research by reporting on the use of different response strategies and by providing initial insights into factors affecting choice of responses.
