Authors: Bálint Erika , Tajti Ádám , Dzielak Anna , Hägele Gerhard , Keglevich György
Published: July 2016

A practical method was elaborated for the synthesis of (aminomethylene)bisphosphine oxides comprising the catalyst- and solvent-free microwave-assisted three-component condensation of primary amines, triethyl orthoformate and two equivalents of diphenylphosphine oxide. The method is also suitable for the preparation of (aminomethylene)bisphosphonates using (MeO)2P(O)H/(MeO)3CH or (EtO)2P(O)H/(EtO)3CH reactant pairs and even secondary amines. Several intermediates referring to the reaction mechanism together with a few by-products could also be identified.
RISK PERCEPTION AND VULNERABILITY OF VALUE: A STUDY IN THE CONTEXT OF COMMERCIAL PROPERTY SECTOR
Authors: BHATTACHARYA-MIS Namrata , LAMOND Jessica
Published: July 2016

The research was developed linking the impact of flood risk on utility, desirability and marketability related to vulnerability of commercial property value. Likert style questionnaire survey was conducted to obtain data from flood affected and un-affected respondents across different designated flood risk zones on key business and perception variables among two groups of business property holders in England. The responses were analysed through a spatial vulnerability model to illustrate the distribution of the vulnerability of value of properties among flood plain business holders on a GIS platform. Majority of respondents perceived that utility of properties may be hampered by flooding and subsequently have an impact on value for property at risk. Those with flood experience gave greater weight to their specific business needs such as the prime location and expected income level than those without flood experience. The implication of the study lies in understanding that flood risk perceptions can shape actions of people at risk towards future increase in resilience having strategic impact on value of property saleability in the future.
ECONOMIC VALUE DETERMINATION AS A STRATEGY FOR BUILDING RESILIENT COMMUNITIES IN THE NIGER DELTA REGION
Authors: AKUJURU Victor A. , RUDDOCK Les
Published: July 2016

In a novel approach to disaster resilience that embodies a multidisciplinary problem solving process in determining the value of damaged property, a framework has been developed for determining the economic value of damages to property due to contamination from human-caused oil spill disaster in the Niger Delta. The framework will result in a reduction of the recovery process of affected communities following an oil spill as they know in advance what will be done and result in standardisation of the valuation process. it will enable the polluter to know the cost of their malfeasance and provide the property owners with the economic value of their polluted property to enable them to continue their livelihood. Professional valuers and property owners are very dissatisfied with the current practice without a standard framework and oil company operators hardly realise the economic cost of disasters imposed on the communities. Reviewing the theory and practice of economic value and ecosystem valuation, a mixed-methodology was employed using questionnaires and expert interviews to ascertain how contaminated wetland property is valued, the professionals involved and their respective roles. The proposed framework will provide a systematic process leading to the determination of the economic value of damages due to contamination of wetlands property.

De la guerre des frontières aux mobilisations
Authors: Coquio Catherine , Message Vincent , Osouf Valérie
Published: July 2016

Face à la guerre des frontières, les réponses politiques oscillent entre le dérisoire et le criminel. Il importe dans ce contexte d’entendre les réfugiés dénoncer les humiliations qu’ils subissent, l’arbitraire des décisions administratives, la présomption de culpabilité dont ils font l’objet, mais aussi réclamer un dépassement des préjugés et une reconnaissance de leurs droits.

L’innovation sans PC
Authors: Calisti Bernard
Published: July 2016

Ce dont tout le monde rêve ! Une innovation fulgurante qui change la donne et rencontre un succès extraordinaire. Mais ce résultat est rare et hasardeux. Il s’avère d’autant plus difficile à atteindre que nombre de chantres de la nouveauté font de l’innovation une sorte de pseudo-religion dans laquelle les croyances l’emportent souvent sur l’examen des faits. L’innovation n’est pas une masse indistincte, une notion absolument vague et indéfinie. C’est une pratique, avec ses règles, ses nuances et ses variations d’intensité depuis l’exploitation commerciale de changements légers, jusqu’au bouleversement des innovations de rupture. Ainsi, quand le succès est au rendez-vous, les marchés se trouvent-ils modifiés, voire bouleversés. Car les effets de l’innovation peuvent-être épidémiques. Cet effet viral est propre à tous les phénomènes sociaux majeurs, qu’ils soient économiques ou artistiques. Rappelons-nous le succès de Cent Ans de solitude de Gabriel García Márquez : après avoir lu l’ouvrage, chaque lecteur se sentait le besoin de partager cette découverte avec quatre ou cinq autres personnes. L’héritage des grandes avancées humaines est de nos jours confronté à une exigence supplémentaire : celle de respecter les choix d’avenir. Les innovations seront dès lors de plus en plus durables ou ne seront pas.
Les enjeux de la territorialité fiscale
Authors: Leroy Marc
Published: July 2016

Par rapport à l’action publique, la fonction territoriale de l’impôt se réfère à la souveraineté géographique de l’Etat, mais est devenue plus complexe sous l’effet de la mondialisation (baisse de la taxation des multinationales, rigueur budgétaire pour les administrations locales). Elle renvoie aussi à la politique de péréquation financière et de développement. Par rapport aux contribuables, la concurrence fiscale entre les territoires nationaux a conduit à la déviance spécifique de certaines catégories socio-économiques. D’autres catégorisations socio-territoriales interviennent : créanciers internationaux de la dette publique vs taxation des citoyens nationaux ; zones compétitives vs zones en retard de développement ; E-commerce échappant à la localisation matérielle de ses activités par le droit fiscal. Enfin, les représentations des contribuables questionnent la légitimité des autorités locales.

Des indicateurs pour optimiser l’allocation des ressources ? Une enquête exploratoire au sein d’un réseau administré
Authors: Dubost Nathalie , Fabre Pascal
Published: July 2016

En France, l’action sociale et médico-sociale est délivrée au sein d’un réseau administré constitué d’associations et de leurs établissements (ESSMS), lesquels sont financés et contrôlés par une entité publique située à trois niveaux géographiques. Face au constat d’écarts injustifiés entre ESSMS comparables, le niveau national du réseau a mis au point un tableau de bord partagé (TDBP) afin d’améliorer l’allocation des ressources. Ce TDBP peut-il remplir cet objectif ? A l’aide du modèle d’Hofstede, nous montrons quel type de contrôle ce TDBP introduit entre le financeur et les ESSMS. Nous présentons ensuite les résultats d’une enquête exploratoire portant sur les pratiques d’allocation des ressources au sein du réseau.
Performance and Usability of Tablet Computers by Family Caregivers in the United States and China
Authors: Tao Hong , McRoy Susan , Kovach Christine R. , Wang Lin
Published: July 2016

Mobile-based health information software offers the potential to support family caregivers who live at home or have difficulty accessing health care centers. The current study examined factors predicting perceived usability and performance of computer tablets among typical family caregivers caring for older adults in their homes in the United States and China. A multi-part study was conducted with 100 caregivers age 55 and older, comprising a short written survey, practice-based observation, and follow-up survey combining standard usability items and open-ended questions. Results show the target population from both regions would be willing and able to adopt new tablet-based software, but participants' attitudes about the complexity of tablets and software present a potential barrier. This finding was true especially among caregivers from China, who expressed more concerns (yet performed equally well) possibly because they had less prior experience with the technology. Results suggest information and training be provided to address caregiver concerns before the introduction of new tablet-based software interventions.

Optical Coherence Tomography and Multifocal Electroretinography in Diabetic Macular Edema: A Neurovascular Relation With Vision
Authors: Nagesh B.N. , Takkar Brijesh , Azad Shorya , Azad Rajvardhan
Published: July 2016

BACKGROUND AND OBJECTIVES:

To evaluate retinal neuropathy in patients with diabetic macular edema (DME) with multifocal electroretinograph (mfERG), and to evaluate the simultaneous impact of retinal neuropathy and vasculopathy on visual acuity in subtypes of DME.

PATIENTS AND METHODS:

This prospective, controlled, investigative study conducted at a tertiary eye care center of Northern India included 79 eyes of 50 treatment-naïve patients with DME (Group 1), 94 eyes of 50 diabetic patients without diabetic retinopathy (Group 2), and 100 eyes of 100 normal volunteers as controls. Comprehensive ocular evaluation along with mfERG and optical coherence tomography (OCT) were performed for all patients. N1 and P1 mfERG waveforms in the two central-most rings of macula were evaluated for amplitudes and implicit time. OCT was used to sub-classify types of DME and evaluate macular thickness, ellipsoid zone (EZ), and external limiting membrane (ELM) disruption. Best-corrected visual acuity (BCVA) relative to other variables was the primary outcome measure. The three groups were compared for all the parameters inclusive of OCT and mfERG patterns. Further, OCT subtypes of DME were analyzed for mfERG waveform patterns.

RESULTS:

All mfERG values were significantly lower in Group 1 and Group 2 as compared to Group 3 (
P
< .05). BCVA strongly correlated with central macular thickness, EZ, and ELM disruption scores in Group 1 (
P
= .001), but correlated modestly with mfERG waveform amplitudes in Group 1 patients with intact EZ and ELM only. BCVA correlated with mfERG amplitudes in patients with neurosensory detachment, but not in those with cystoid macular edema.

CONCLUSIONS:

Neural changes set in before the clinical changes related to vasculopathy manifest in diabetic patients. Neuroretinopathy in patients with DME affects all retinal layers symmetrically in early stages, but impacts the middle retinal layers severely in advanced disease form. BCVA correlates with electrophysiological changes till the time morphological features are visible when stronger correlation is seen with anatomical disruption.

Posterior Segment Distortion in Ultra-Widefield Imaging Compared to Conventional Modalities
Authors: Nicholson Luke , Goh Li Yen , Marshall Elena , Vazquez-Alfageme Clara , Chatziralli Irini , Clemo Monica , Hykin Philip G. , Sivaprasad Sobha
Published: July 2016

BACKGROUND AND OBJECTIVES:

To describe posterior segment distortions in Optos ultra-widefield images (Optos 200TX; Optos, Dunfermline, United Kingdom) compared to Topcon retinal camera images (Topcon, Tokyo, Japan) using optic disc dimensions and exploring a proposed method for correcting these distortions.

PATIENTS AND METHODS:

Comparative image analysis study on 20 eyes with color fundus images from Optos and Topcon. A model eye with vertical and horizontal grids imaged with Optos in the conventional position and rotated 90° was analyzed.

RESULTS:

Mean vertical-to-horizontal disc diameter ratios were 0.956 [95% CI, 0.919–0.993] for Optos and 1.083 [95% CI, 1.045–1.121] for Topcon (
P
< .001). This was 0.910 in the conventional position and 1.072 with the object rotated 90° for the model eye with Optos and 1.008 and 0.999, respectively, using Topcon. The average of the measurements taken using both images from Optos yielded a ratio of 0.987.

CONCLUSION:

Optos incorporates a consistent horizontal stretch to images. Combining images taken at right angles reduces the distortion.

Authors: Paulus Yannis M. , Butler Nicholas J.
Published: July 2016

Posterior ophthalmomyiasis interna is a rare, potentially devastating infestation of the posterior segment by fly larvae. The authors report the first demonstration of spectral-domain optical coherence tomography (SD-OCT) (Spectralis; Heidelberg Engineering, Heidelberg, Germany), wide-field angiography (Optos, Dunfermline, Scotland) and photography, and fundus autofluorescence with temporal progression during a period of 6 months. A 12-year-old white female presented with acute, painless vision loss with hand motions visual acuity. No larva was visible, so she was treated with oral ivermectin. Visual acuity improved to 20/80. OCT demonstrated hyporeflective spaces of the outer retina and retinal pigment epithelium, which resolved during 1-month period with improved ellipsoid layer by 6 months. Fundus autofluorescence demonstrated linear hypoautofluorescent tracks.

Authors: Wang Sophia Y. , Ghodasra Devon H. , Amin Sejal R. , Mian Shahzad I. , Jayasundera K. Thiran
Published: July 2016

An 85-year-old man with remote thermal sclerostomy and Descemet's stripping automated endothelial keratoplasty (DSAEK) in the right eye presented urgently for pain and blurred vision in that eye. Examination revealed bleb purulence and vitreous cellular aggregates concerning for endophthalmitis. Microscopy of a vitreous sample revealed yeast and pseudohyphae. He developed corneal infiltrates consistent with fungal infection. Therapy included topical, intravitreal, and systemic antifungals voriconazole and amphotericin. Fungal pathogens have very rarely been reported to cause bleb-associated endophthalmitis and should be considered in addition to bacterial pathogens. Vitreous aspiration should be performed in all cases of bleb-related endophthalmitis and include fungal studies.

Hormigones reforzados con fibras de acero
Authors: Fernández Cánovas Manuel
Published: July 2016

Durante las tres últimas décadas se ha producido un gran desarrollo en la industria de la construcción, desarrollo que ha alcanzado, no sólo a las técnicas de diseño y cálculo, sino también a la tecnología del hormigón y, por supuesto, al propio hormigón. Y es lógico que esto sea así, pues refiriéndonos concretamente al caso del hormigón hemos de decir que, a pesar de su larga vida, pocos avances ha experimentado hasta nuestros días este noble material.
El hormigón —el material más empleado en nuestras obras de ingeniería— es un compendio de virtudes pero con grandes lacras; es pesado, tiene una relación muy baja entre su resistencia a tracción y compresión; su relación peso-resistencia es excesivamente alta; su estabilidad de volumen deja mucho que desear, siendo su inestabilidad fuente de importantes problemas patológicos. Su capacidad para absorber energía antes de la rotura es baja, su durabilidad es muy sensible a su proyecto y ejecución, etc. Sin embargo, y a pensar de estos inconvenientes, el hormigón tiene tantas ventajas y tantos argumentos a su favor que se puede considerar, sin duda, el rey de los materiales de construcción.

Soluciones actuales al problema de las construcciones docentes en Iberoamérica. Batería de aulas de uso común
Authors: Ortiz Aldo H.
Published: July 2016

Sintetizando conceptos vertidos en el prólogo de la obra original, la Arqta. Liliana Rainis, expresa: «Este trabajo marca dos aspectos de innegable mérito: por un lado el desarrollo de todas las etapas de un proceso de diseño entendido en sus fases de: diseño específico, construcción y uso-verificación, y por otro lado, la explicación y aplicación de un método de diseño total o ecodiseño. Ambos aspectos raramente se encuentran unidos en las publicaciones arquitectónicas sobre el «diseño», ya se trate de libros o de revistas especializadas; el primero de ellos al llegar a la verificación posibilita avanzar sobre ese mero «análisis» o «interpretación» que generalmente permite la bibliografía, para completar la verdadera crítica hasta la etapa evaluativa, donde el diseñador se transforma en su propio crítico. El segundo aspecto desarrolla una verdadera metodología, puesto que se apoya en un estudio previo, delineando un cuerpo teórico que podría conformar aquello que el autor denomina ecodiseño. Coherente con todo el proceso que desarrolla, el trabajo está organizado en las cuatro partes que estructuran dicho proceso: el diseño, la ejecución, la verificación, el epílogo».
Se trata, por lo tanto, de planteamientos y desarrollos que en primer lugar señalan los problemas casi permanentes de la universidad argentina en su contexto socio-político y en su dificultad de dar respuestas físicas concretas a una población universitaria creciente, problemática de por sí interesante y de fundamental importancia en nuestro país.
Finalmente, siguiendo la propuesta del trabajo en sus conclusiones, es un estímulo a continuar en el estudio del problema, tanto particular como general, frente a la situación mundial de las últimas décadas, donde se ha incentivado el desarrollo de nuevas universidades, ya sea en los planes pedagógicos como en las estructuras físicas (recordemos los ejemplos europeos, de Estados Unidos, de Canadá, etc.), propiciando el debate extensivo y profundo que abarque la universidad en su doble aspecto, de actividad-conocimiento y de objeto arquitectónico-urbanístico complejo y funcional, entre profesionales, docentes y estudiantes.
Factors Influencing Consumer Adoption for Network Fellowship Auction in Taiwan
Authors: Chen Yi-Fen , Tsai Chia-Wen , Tseng Yen-Fang
Published: July 2016

The emerging online economy in recent years has facilitated the rapid growth of e-commerce, such as Internet bank, e-wallet, and electronic bidding. Network fellowship auction is a collective effort by people who network and pool their money together by Internet in order to invest in and support efforts initiated by other people or organizations. Network fellowship auction has replaced conventional fellowship auction by offering a new safer and faster financial instrument. This research investigated the determinants of network fellowship auction user acceptance, including consumer perceived risk, perceived value, computer self-efficacy, and product involvement. An online survey was used with a sample of 446 respondents. Structural equation models (SEM) were used to examine hypotheses in the theoretical framework. The results showed that consumer perceived risk substantially negatively influenced perceived ease of use and intention; consumer perceived value positively influenced perceived usefulness; consumer computer self-efficacy positively influenced perceived ease of use. Additionally, consumer perceived usefulness, perceived ease of use, and product involvement positively influenced consumer intention.
Knowledge Management in 2016
Authors: Lofaro Ronald John
Published: July 2016

This article will very briefly indicate some current topics and developments in the field of cognitive engineering (CE), knowledge engineering (KE) and knowledge management (KM). From there, it will present an extensive look at the development and usage of new Dephi model, starting with its origin in the 1980's and later, its successful usages with modifications into the early 2000's. An effort will be made to show how that new Delphi, called the small-group Delphi paradigm (SGDP), can now be again modified to take advantage of expansions in the field of KE/KM and of the great strides in communication and computer technology. Next, an example of how such an up-dated, modified SGDP could be applied to a current, serious problem in aviation, as well as an indication of other issues for which this new Delphi also could provide useful results.
A Contingency Approach to Knowledge Management
Authors: Handzic Meliha , Ozlen Kursad , Durmic Nermina
Published: July 2016

A contingency perspective of knowledge management recognises the need for a fit between knowledge management solutions (KMS) and decision making contexts which they support. In order to determine the best fit, a field survey was carried out to investigate the impact of two different types of KMS (technical and social) on decision makers' behaviour and performance in different decision contexts (simple and complex). The results provide partial support for the contingency view. As expected, the study identified social KMS as the best fit for complex contexts, based on subjects' superior performance from comparable adoption of both KMS. In contrast, the study identified that both KMS were an equally good fit for simple contexts, based on similar levels of subjects' performance, but social KMS was preferred in terms of adoption. These findings contribute to much needed empirical evidence for research and provide useful guidance for practice. However, their limitations warrant further study.

Authors: Hashim Khairuddin , Al-Sharqi Laila , Kutbi Ibrahim
Published: July 2016

Social media has become pervasive, impacting the social fabric and culture of our society. This study investigates differences and similarities between students' and faculty's perceptions of social media impact on social behavior of students. Data were collected using a specially designed survey. The sample size was 2605 students and 507 faculty of different genders and ages. Research outcome indicates that students and faculty are familiar with and are immersed in social media use. The findings support the advantages of social media use on students' social behavior and do not indicate any obvious disadvantages. The findings of the study include identification of dominant group perceptions pertaining to advantages and disadvantages of social media use on social behavior of students. Common concerns of the two groups pertaining to students include physical inactivity, social introversion, exposure to bullying and domination attitudes; and mental dullness. These findings can help discern possible issues relating to use of social media affecting social behavior.
A Case Study on Computer Supported Collaborative Learning in Spanish Schools
Authors: Cabezas Marcos , Casillas Sonia , Hernández Azucena
Published: July 2016

This article presents the main results from eight case studies carried out at different Spanish schools. Using a common protocol, the authors compared different cases of schools in which computer-supported collaborative learning experiences were carried out in order to identify what standard actions they had in common. In order to facilitate data collection and analysis, the authors opted for a mixed methodology, the instruments being interviews, observation, document analysis, a monitoring guide for the teachers and a semantic differential for the students. It was concluded that collaborative learning strategies favour students, since all of them benefit from constructing knowledge together, sharing responsibilities, taking ideas more in depth, having greater autonomy and control over their own learning, and helping each other in the process.
Application of the Complementary Functions Method to an Accurate Elasticity Solution for the Radially Functionally Graded (FG) Rotating Disks with Continuously Variable Thickness and Density
Authors: Boğa Cem , Yildirim Vebil
Published: July 2016

In this work, elastic stress and deformation distribution through the radial direction of FG rotating disks are accurately calculated by employing the complementary functions method. A parabolic variation of the thickness is used for the concave, linear and convex thickness profiles. The inner and outer surfaces of the FG disk are assumed to be ceramic-rich and metal-rich, respectively. Between these two surfaces material properties vary radially according to Mori-Tanaka grading rule. After confirming the present results with the analytical results for the uniform disk with power-law graded rule, the effect due to many parameters such as angular velocity, metal-ceramic pairs, and material grading index on the stresses and displacements is investigated.

Published: July 2016

Bone drilling is often used in trauma care, orthopedic and other type of surgical procedures. The elevated temperatures caused by friction may lead to temperature induced bone necrosis. This paper presents an analysis of the effect vibration assisted drilling has on the drilling temperature of the compact bone.The experimental setup was developed and two-type experiments have been conducted. The main aim was to analyze the low frequency vibrations assisted drilling effect on the drilling temperature of poly-methyl methacrylate (PMMA) and bone samples. The temperatures at the exit hole were measured using the thermal camera. The rotational speed of the drill, applied force, parameters of the drill and the samples were considered as constant, whereas the amplitude and frequency of vibrations were varied during the experiments. The obtained experimental data showed the decrease in the drilling temperatures of the vibrated bone samples, as compared to the conventional drilling. It should be noted that further investigation and research related to the vibration assisted drilling should be carried out using different type of bone samples and experimental conditions.

Published: July 2016

The paper presents the test results on the fatigue crack growth under bending, torsion and proportional bending with torsion. The tests were performed at the fatigue test stand MZGS-100 at the constant amplitude of moment MB = MT = MBT = 15.84 N⋅m and stress ratio R = -1. Specimens with rectangular cross-section in fatigue tests were used and were made of EN AW-2017A aluminium alloy. The EN AW-2017A alloy consists of α grains and the Al2Cu phase. The effect of the microstructure on the crack paths in specimens was observed. Transcrystalline cracks through grains of the α phase have been usually observed on the fractures.
Geometrical Structure for Endoprosthesis Surface Lubrication and Wear Prognosis
Authors: Wierzcholski Krzysztof
Published: July 2016

It can be stated that over the last ten years in the European Union, the number of bone fractures caused by osteoarthritis has increased twofold. More than 100,000 hip or knee joints in total were implanted in Germany during one year. Within ten years, 5% of them have failed by aseptic loosening.The non-invasive determination of friction forces and control of their values during lubrication of cartilage cells on the superficial layer of human joint surfaces before implantation has a significant but not sufficient impact on the observation of the early abrasive wear of the cartilage joint and development of osteoporosis. From this fact was drawn the inspiration for the performed investigations related to the endoprosthesis surface parameters because knowledge of the roughness of prosthesis surfaces and friction forces and their control methods permits provision of a necessary standard deviation of the gap height and finally information about the implantation possibility. This paper has been prepared based on the objective of European Project UE Grant IRSES,612593, 2013-2016 to represent the methodology and goal of the idea described in and make a wider discussion possible on this subject for further developments during the realization.

Simplified Method of Resin Infusion Process Simulation on Example of Formula Student Lightweight Components
Authors: Wnuk Maciej , Iluk Artur
Published: July 2016

In the production of lightweight composite parts, resin infusion is the leading technology due to its excellent quality-to-cost ratio [1], [2]. Not only is there no need to use expensive equipment such as autoclaves, but the resulting fiber to resin ratio is very high, which makes parts very stiff, strong, and lightweight [3], [4]. Other advantages include a glossy surface and a structure that free of macro-pores, provided when the process is well prepared. The equipment used in this process allows one to manufacture part in virtually any size and shape [5]. The main difficulty is to design resin feed lines in way that will saturate fabrics until the resin gels. To facilitate this process design finite element codes can be used to simulate the flow of resin during infusion [6].

The use of laser systems in the industrial manufacture of complex geometry details is growing. This phenomenon takes place thanks to laser technologies, such as selective laser sintering (SLS), direct laser metal sintering (DLMS) and selective laser melting (SLM) that make possible, in addition to production of details with complex geometric shapes, also the fast, cheap and effective restoration of damaged elements of the details. However, despite the abundant advantages of the above-mentioned technologies, the details produced on the basis of these innovative methods have typical problems (large value of surface roughness, low wear resistance). In the paper, the influence of changes of the principal technological parameters of the laser polishing on the technological characteristics of the external surface of details built by SLS was studied. Changes of the laser’s technological parameters impact the amount of energy supplied onto the area under processing. Thus, the correct selection of the technological parameters of the laser beam positively affect the microstructure and topography of the top surface layer of the manufactured details, its chemical composition and physical properties as well as diffusive processes in the laser beam impact area.

Published: July 2016

Cells of the immune system undergo activation and subsequent proliferation in the normal course of an immune response. Infrequently, the molecular and cellular events that underlie the mechanisms of proliferation are dysregulated and may lead to oncogenesis, leading to tumor formation. The most common forms of immunological cancers are lymphomas, which in dogs account for 8%-20% of all cancers, affecting up to 1.2% of the dog population. Key genes involved in negatively regulating proliferation of lymphocytes include a group classified as tumor suppressor genes (TSGs). These genes are also known to be associated with progression of lymphoma in humans, mice, and dogs and are potential candidates for pathological grading and diagnosis. The aim of the present study was to analyze TSG profiles in stimulated leukocytes from dogs to identify genes that discriminate an activated phenotype. A total of 554 TSGs and three gene set collections were analyzed from microarray data. Cluster analysis of three subsets of genes discriminated between stimulated and unstimulated cells. These included 20 most upregulated and downregulated TSGs, TSG in hallmark gene sets significantly enriched in active cells, and a selection of candidate TSGs, p15 ( CDKN2B), p18 ( CDKN2C), p19 ( CDKN1A), p21 ( CDKN2A), p27 ( CDKN1B), and p53 ( TP53) in the third set. Analysis of two subsets suggested that these genes or a subset of these genes may be used as a specialized PCR set for additional analysis.
