description: The paper examines the role of land access in youth migration and employment decisions using a two wave panel data set from the Living Standards Measurement Study—Integrated Surveys on Agriculture (LSMS-ISA) from Nigeria. Overall, the findings show that the size of expected land inheritance is significantly and negatively associated with long distance migration and migration to urban areas, while a similar impact is negligible when a broader definition of migration is adopted and when migration is deemed as temporary. A more disaggregated analysis by considering individual characteristics of the youth shows that results are more elastic for older youth and those that are less educated, while we find no difference when comparisons are made by gender. Similar analysis on the influence of land access on youth employment choices shows strong evidence that the larger the size of the expected land inheritance the lower the likelihood of the youth being involved in non-agricultural activities and a higher chance of staying in agriculture or the dual sector. The results further reveal that youth in areas with a high level of agricultural commercialization and modernization seem to be more responsive to land access considerations in making migration and employment decisions than are youth residing in less commercialized areas. Finally, the results from the differential analysis suggest that rural-to-urban migration and the likelihood of youth involvement in the dual economy is more responsive to the size of the expected land inheritance for less educated youth as compared to more educated ones.

description: Η διδακτορική διατριβή έχει αντικείμενο μελέτης το έργο του ελληνιστικού ποιητή Λυκόφρονα, Αλεξάνδρα. Οι μυθολογικές αναφορές ως κυρίαρχο γνώρισμα, που διατρέχει το συγκεκριμένο ποίημα, γίνονται αφορμή για την αφήγηση της δράσης των προσώπων της Αλεξάνδρας. Η εστίαση της μελέτης γίνεται συγκεκριμένα στη δράση των αρρένων και των ποικίλων πτυχών της. Με τη βοήθεια των νεωτερικών αρχών της κοινωνιολογίας και του κλάδου των «σπουδών του φύλου» (gender studies) οι ταυτότητες των ανδρικών χαρακτήρων διακρίνονται στην ηγεμονική, την υποτακτική, τη συνεργατική ή συνενοχική και την περιθωριακή. Οι ίδιοι ανδρικοί χαρακτήρες αποδεικνύουν την πολλαπλότητα των κοινωνικών τους αντιδράσεων σύμφωνα με τις περιστάσεις, αξιολογούνται και κατανέμονται σε κάθε μια από τις παραπάνω ταυτότητες. Η παραπάνω διάκριση και ταξινόμηση βοηθά στην ερμηνεία των δράσεων τους με μια πιο επιστημονική, αλλά και πιο διεισδυτική ματιά. Ο Ηρακλής, ο Αχιλλέας, ο Έκτορας, ο Διομήδης, ο Αίαντας ο Λοκρός, ο Αίαντας ο Τελαμώνιος, ο Φιλοκτήτης, ο Αινείας, ο Μενέλαος, αλλά και ο Μέγας Αλέξανδρος ως το μοναδικό ιστορικό ανδρικό πρόσωπο, γίνονται το αντικείμενο της ενασχόλησης στη διδακτορική διατριβή σε μια δημιουργική αφομοίωση της αρχαϊκής, κλασικής, ελληνιστικής και σύγχρονης εποχής αποδεικνύοντας την ενότητα των ανδρικών δράσεων των διαφορετικών εποχών, αλλά και τη διαφορετικότητα των κοινωνικών συμβάσεων.

description: (This paper is based on a joint presentation given at Icarus Interstellar’s Starship Congress, August 15-18, 2013. This work forms the basis for Project Astrolabe, at Icarus Interstellar.) http://www.icarusinterstellar.org/introducing-project-astrolabe-navigating-the-future-of-civilization/ Though the concept of Existential Risk or Xrisk denotes risks to our very existence, it will be shown that Xrisk is far from intractable or imponderable. Because of the subtypes described in our session below (Permanent Stagnation and Flawed Realization), humanity can do much to improve the prospects for Earth-originating intelligent life tomorrow by working to improve its prospects today. This begins with directly mitigating the extinction risks that can be mitigated, and with safeguarding—to the best of humanity’s abilities—the scientific, cultural, and biological record so that future recoveries are possible if needed. The Vessel proposal attempts a unified approach to this work. If existential risk is well mitigated, the prospects for Earth- originating life over the very long term are shown to be expansive. (Xrisk 101) is divided into two parts, and mirrors the format of the original presentation. The first part, authored by Heath Rezabek, will cover the fundamentals of Xrisk, and update on the Vessel project, a framework for preserving the cultural, scientific, and biological record in resilient facilities, on Earth and beyond. The second part, authored by Nick Nielsen, will explore the longer term implications of overcoming Xrisk for the future of civilization.

description: Conservation Agriculture (CA) aims to concurrently promote agricultural productivity, climate resilience and other environmental objectives related to sustainability. The evidence base for CA and other practices of climate-smart agriculture (CSA) in Sub-Saharan Africa is becoming better established. We review this evidence to address whether CA meets CSA objectives and why adoption rates by smallholders remain generally very low. As part of the review, we develop hypotheses for expected CA adoption under different socioeconomic and agro-ecological conditions, and consider promising options for enabling CA to better contribute to the CSA objectives. Our results are largely in agreement with the nascent literature where CA is found to contribute positively to CSA productivity and adaptation/resilience objectives, although the degree of success varies considerably by regional, farm and household characteristics. The evidence is equivocal on the potential for CA to enhance soil carbon sequestration and reduce greenhouse gas emissions. Overall, we find that capital-intensive (mechanized) CA is more likely to be adopted in areas of economic dynamism where capital is cheap relative to labor. Labor-intensive CA practices are more likely to be adopted in regions of economic stagnation where capital is expensive and labor is abundant and cheap. The climate-smartness of CA can be enhanced in a number of ways: reframing and adapting CA to location-specific economic and biophysical conditions, integrating CA with other CSA practices such as agroforestry, and by increasing the use of complementary productivityenhancing inputs such as inorganic fertilizers and organic manure. Other options to make CA climate-smart include conditional subsidies, market and value chain development to improve farmers’ access to CSA-promoting inputs, linking CA to payments for environmental service schemes (e.g., carbon credits), greater and more effective public spending on research and development to build evidence on the adaptation and mitigation potential of CA, and an improved enabling policy environment for private investment in input and farm commodity markets.

description: We have investigated the N2O–HDO molecular complex using ab initio calculations at the CCSD(T)-F12a/aug-cc-pVTZ level of theory and using cavity ring-down spectroscopy to probe an HDO/N2O/Ar supersonic jet around 1.58 μm. A single a-type vibrational band was observed, 13 cm−1 redshifted compared to the OH+OD excited band in HDO, and 173 vibration-rotation lines were assigned (Trot ≈ 20 K). A weighted fit of existing microwave and present near infrared (NIR) data was achieved using a standard Watson's Hamiltonian (σ = 1.26), producing ground and excited states rotational constants. The comparison of the former with those calculated ab initio suggests a planar geometry in which the OD rather than the OH bond in water is almost parallel to NNO. The equilibrium geometry and dissociation energy (De = –11.7 kJ/mol) of the water–nitrous oxide complex were calculated. The calculations further demonstrate and allow characterising another minimum, 404 cm−1 (ΔE0) higher in energy. Harmonic vibrational frequencies and dissociation energies, D0, were calculated for various conformers and isotopic forms of the complex, in both minima. The absence of N2O–D2O from dedicated NIR experiments is reported and discussed.

Stable lead isotopes, trace metals and radionuclides in sediments of the Alligator Rivers Region to assess impacts of uranium mining
Creators: name: Sinclair, Alison
Publisher: name: Charles Darwin University
Year: 2015

description: Post-mining environmental protection is the key to successful rehabilitation; especially where runoff and erosion from rehabilitated mine sites can lead to pollution and contamination of the surrounding land and watercourses. Australian guidelines recommend that tailings materials from uranium mining and milling be contained without any detrimental impact on the environment for at least 1000 years. The Alligator Rivers Region (ARR) in Northern Australia includes a large area of Kakadu National Park (KNP), which is world heritage listed for its conservation value. Within the ARR are numerous uranium (U) anomalies and prospects, one current operational U mine and several former U mines. The aim of this study was to develop a sensitive methodology to assess the impacts of U mining on sediments in the ARR. This involved an appraisal of stable lead isotopes, radionuclides and trace metals within sediments and soils, including surface and core samples, to determine the off-site impacts from a spatial and temporal perspective. The sites investigated were Ranger Uranium Mine (currently operating mine site), Nabarlek uranium mine (rehabilitated former mine site), Koongarra Mineral Lease (former exploration activities but not mined) and Ranger Anomaly 2 (identified U orebody within KNP). The study found that there are localised areas on and adjacent to the mine sites and anomalies where soils had elevated levels of trace metals and radionuclides. Lead isotope ratios are highly radiogenic in some samples, indicating the presence of U-rich material. Erosion products with more radiogenic Pb isotope ratios have also deposited in sediments downstream of the former ore bodies. However, there is no indication that the radiogenic erosion products found on the mine sites/anomalies have significantly contaminated sediments further downstream. The monitoring methodology is able to determine very small percentage (~1 per cent) contributions of erosion products equivalent to very low additional mine or orebody derived Pb/U concentrations of less than 0.1 mg kg-1 Pb and 0.05 mg kg-1 U, compared to background concentrations of typically 11 mg kg-1 Pb and 3 mg kg-1 U. This contribution is less than the concentration variability observed within the sediments and would not be discernible without the use of lead isotope ratios. This research project demonstrated that a sediment monitoring approach integrating lead isotope ratios with trace metals and radionuclides can deliver more information than metal and radionuclide concentrations alone, especially in terms of identifying sediment sources and their respective contributions to mining impacts. The isotopic monitoring methodology can be readily reproduced and transferred to other sites and it will ultimately provide better measurement of rehabilitation success.

description: In this study, it was aimed to investigate the chemical composition and antioxidant activities of two Euphorbia species. The major component of the fatty acid compositions obtained from the petroleum ether extracts was identified as palmitic acid for Euphorbia gaillardotii and Euphorbia macroclada. The main constituents of the essential oils were identified as arachidic acid for E. gaillardotii and tetratetracontane for E. macroclada. Among the 27 studied compounds, hesperidin, rutin, hyperoside and quinic, malic, gallic and tannic acids were found to be the most abundant compounds in the two Euphorbia species. The methanol extracts of E. gaillardotii and E. macroclada showed strong antioxidant activity in all tested methods. Particularly, IC50 values of E. macroclada methanol extract that was the richest in terms of total phenolic-flavonoid contents were found to be lower than α-tocopherol and butylated hydroxytoluene in β-carotene bleaching, 2,2-diphenyl-1-picrylhydrazyl free and ABTS cation radical scavenging methods.

description: The resinous exudate, three meroterpenes, namely bakuchiol (1), 3-hydroxybakuchiol (2), 12-hydroxyisobakuchiol (3), and one furanocoumarin, psoralen (4), were isolated from the leaves of culen (Psoralea glandulosa). In addition to these, two semi-synthetic derivatives, bakuchiol acetate (5) and bakuchiol methyl eter (6), were obtained from 1, and were subsequently evaluated in vitro for the inhibitory effect of resin and compounds on the mycelial growth of Botrytis cinerea Pers.: Fr. and Phytophthora cinnamomi Rands. The resinous exudate inhibited the mycelial growth of both the pathogens, while bakuchiol (1) exhibited an inhibitory effect on the mycelial growth of B. cinerea up to 94% at a concentration of 150 mg/L and psoralen (4) reduced the mycelial growth of P. cinnamomi up to 80% at a concentration of 150 mg/L. These compounds have the ability of blocking the development of mycelial growth and may be used as a potential biopesticide in the agricultural sector once the in vivo test results have been validated.

Extinction and environmental change: testing the predictability of species loss

description: Current extinction rates are thought to be significantly higher than at any point in the last 65 million years. Such a loss of species could have serious implications for human well being, as humanity depends upon services that are derived from diverse, functioning ecosystems. Given the predicted increase in human alterations to the global biosphere in the next century, minimis- ing the loss of species, both now and in the immediate future, has become a prime concern, and has led to policy driven initiatives designed to halt or slow biodiversity loss. Tackling this loss of diversity requires an understanding of current, and recent, extinction events, as well as how future environmental change may alter the probability of a species persisting. In this thesis I explore, using small-scale aquatic microcosms, modelling, and data from real-world extirpations, the predictability of extinction events, both historic and future, and how environmental change may alter the persis- tence of populations alone and in a community context. I present results that suggest our ability to accurately infer the current rate of species loss will depend upon the method used to infer extinction, the amount of a habitat historically searched when looking for a species, and also the underlying population dynamics of that species, which can be altered by environmental change. I demonstrate that the timing of extinction events, driven by various rates of environmental change, can be predicted using a simple phenomenological model, if a detailed knowledge of how the environment will change over time is known. Lastly, I show that environmental change can interact with community assembly processes to alter the probability of a species persisting, and thus community composition. The results of this work contribute to our understanding of current, and future, extinction events, and provide a basis for using quantitative approaches to inform conservation decision-making.

description: A fluidized bed reactor, for the first time, was employed to investigate the partial oxidation of propane to acrylic acid over Mo1V0.3Te0.23Nb0.12Ox catalyst. Effects of temperature, oxygen concentration, steam concentration, space velocity, and dilution with different sizes of SiC were studied and discussed. The reaction in the fluidized bed was compared with the reaction in the classical fixed bed. The results indicated that at constant temperature propane conversion obtained in the fixed bed reactor was higher. But the fluidized bed recompensed it by higher acrylic acid selectivity leading to acrylic acid yields and formation rates considerably over the fixed bed. In the fluidized bed reactor, an enhancement in the acrylic acid selectivity was observed over fixed bed at similar conversions. It is suggested that passing a large portion of gas phase oxygen through bubbles allows operation under lower oxygen partial pressure, which favors the desired reaction path. With the heat sink feature of the diluent, the catalytic performance is more influenced by dilution in the fixed bed. However, hot spots are less likely to occur in the fluidized bed and dilution has little effect on the catalytic performance. However, propane conversion increases slightly by increasing SiC particle diameter due to better fluidization quality.

description: Multiwalled carbon nanotubes (MWCNTs) were added to polyacrylamide (PAM) hydrogels in different proportions to tune their electrical and mechanical properties. The choice of MWCNTs as a reinforcement is justified by the fact that these are highly conducting, fairly stable and flexible particles. A series of MWCNT/PAM hydrogels were prepared by freezing method. The characteristic absorption peaks at 1480 and 1213 cm−1 in the FTIR spectra reveal that MWCNTs are embedded in the PAM hydrogels. Powder x-ray diffractograms and thermogravimetric analysis (TGA) images show that the MWCNT/PAM hydrogels are crystalline, more thermally stable and have a higher electrical conductivity than a traditional PAM hydrogel. Scanning electron micrographs reveal about reduced pore size, homogeneous and denser texture. The swelling properties of all these hybrid hydrogels were found to be better than those of the parent PAM hydrogel. The Li–Tanaka equation was employed to produce the swelling parameters. The diffusion coefficients (Dc) of PAM hydrogel is 10 times higher than the literature value. 0.8% MWCNTs reinforced PAM hydrogel has excellent τc and electrical conductivity (0.76 mS/cm) with improvements in all properties. Lower Dc of 0.8% MWCNTs/PAM hydrogel reveal that extent of crosslinking is much important than density of the system for a better collective diffusion of the respective solvent.

description: Introduction: Adrenocortical carcinoma (ACC) is a rare disease with a poor prognosis and limited therapeutic options. Aim: The aim of this study was to assess the anti-proliferative effect of combinatorial targeting of the PI3K/Akt/mTOR pathway with different drugs and simultaneous targeting of the MEK/Raf/ERKpathway in H295R adrenocortical cancer cells. Material and Methods: The cytotoxicity of LY294002 (pan-PI3K inhibitor), everolimus (mTOR inhibitor), BEZ235 (dual PI3K/mTOR inhibitor) and U0126 (MEK1/2 inhibitor) was assessed by Alamar blue assay in the H295R cell line. After finding the maximal cytotoxic concentrations for all inhibitors, we used suboptimal concentrations for experiments where multiple agents were used simultaneously. Everolimus and BEZ235 were kindly provided by Novartis, Switzerland; LY294002 and U0126 were commercially available. Results: While everolimus, BEZ235 and LY294002 caused 20±6%, 15.6±6% and 11±1% cytotoxicity when used as single agents, co-treatment of cells with everolimus and BEZ235 showed a synergistic cytotoxic effect of 54±9% (p=0.007) (the strongest effect for combination of two inhibitors in our system, N=3 independent experiments). Addition of LY294002 to everolimus and BEZ235 increased the effect further to 65±7%. We also explored the potential benefit of combined inhibition of PI3K/mTOR and MEK1/2. Addition of U0126 to BEZ235 had a synergistic effect (42±3% vs 14±5% and 15±5.6% alone, respectively, N=3 independent experiments). We observed only an additive effect if the MEK1/2 inhibitor was added to everolimus alone or in combination with BEZ235. Conclusions: The combination of agents inhibiting PI3K/Akt/mTOR and MEK/Raf/ERK pathways results in a synergistic cytotoxic effect. Our results suggest also that multiple mode of inhibition of the same pathway may result in a greater cytotoxic effect in adrenocortical cancer cells which cannot be achieved by simple dose escalation. We suggest that new combinations targeting those pathways require further investigation to improve the treatment of ACC patients.

description: Abstract

Within the framework of an ongoing doctoral research into the technology and decoration of Greek helmets,, we present the Non-Destructive use of Synchrotron Radiation X-Ray Diffraction and Neutron Diffraction at the CCLRC Daresbury and ISIS laboratories respectively,  Two early Corinthian type helmets from the National Museum of Wales at Cardiff, whose sampling was prohibited by the fine preservation of the pieces, were analysed at ISIS-ROTAX. Neutron diffraction allowed interpretation of their manufacture method and the identification of areas that were original to one of the helmets, as compared to later additions.  In addition, corrosion and small fragments from two Illyrian type helmets from archaic period burials at Archontiko Cemetery, Greece were investigated using Synchrotron Radiation X-Ray Diffraction (SR-XRD) at station 14.1 and flat-plate geometry SR-XRD on the high resolution station 2.3 at Daresbury Laboratory. A small sample from one helmet was also analysed using Neutron diffraction at the ISIS-ROTAX station at Rutherford Appleton Laboratory. This part of analysis sought to detect Cu/Sn intermetallic compounds, whose presence cowould offer evidence for the presence of tinning.Tinning of a helmet could be for protective (wear resistance), economical (possibly to imitate silvering) or aesthetic motives. It would however, affect the visibility of a warrior on the battlefield and mark his status or even his affiliation to a particular troop. This is a pilot study. Only by investigation of numerous helmets can the occurrence and frequency of tinned helmets be examined and placed in a historical context.

description: This paper examines how the Balanced Scorecard (BSC) and Digital Maturity Models (DMM) can be integrated as strategic management tools for Digital Transformation (DT) in manufacturing companies. The paper first presents the theoretical foundations of both models and then demonstrates their application in the context of digitalization. The BSC approach is enhanced with specific digital Key Performance Indicators (KPIs) and perspectives, while the acatech Industry 4.0 Maturity Index serves as an assessment framework for digital maturity. The integration of both models is presented in a matrix that links strategic objectives with operational development stages. This combined methodology provides companies with a structured framework to plan, implement, and monitor their Digital Transformation, considering both strategic alignment and operational maturity.
On the relationships between the distribution of failure-causing inputs and effectiveness of adaptive random testing

description: Recently, adaptive random testing (ART) has been developed to enhance the fault-detection effectiveness of random testing (RT). It has been known in generalities that the fault-detection effectiveness of ART depends on the distribution of failure-causing inputs, yet this understanding is in coarse terms without precise details. In this paper, we conduct an in-depth investigation into the factors that have an impact on the fault-detection effectiveness of ART. This paper gives a comprehensive analysis of the favourable conditions for ART and, hence, provides a guideline for testers to decide when to use ART instead of RT.
title: Casse-Noisette. Du conte au ballet, ou comment transposer le merveilleux
Publisher: name: Université Toulouse - Jean Jaurès

description: Dès la fin du XVIIIe siècle, le ballet a partie liée avec le conte. Casse-Noisette, Le Lac des cygnes, La Belle au bois dormant, Giselle, Coppélia, Cendrillon… Cette liste ne constitue pas une histoire exhaustive du ballet, mais le coeur d’un répertoire qui souligne un rapport entre deux expressions : le littéraire et le chorégraphique. La seule aventure littéraire du conte est déjà en soi d’une grande complexité. Elle reconsidère les formes brèves et pose la question des réécritures successives. Dans un contexte aussi foisonnant, on peut se demander ce qui a touché chacun des créateurs de la longue généalogie de Casse-Noisette, des premiers écrivains, Hoffmann et Dumas père, au musicien Tchaïkovski, en passant par Vsevolojski, le directeur des Théâtre Impériaux et les deux chorégraphes Petipa et Ivanov.
Sustainable development of silk industry in Northeast Thailand

Publisher: name: Charles Darwin University

description: Northeast Thailand is renowned for the quality of its hand-woven silk production. Silk production is a traditional, cultural heritage handed down through generations. It has become main or supplementary income source for many families in the north-eastern rural villages. Family-based silk producers, such as silk weavers and silk farmers associated with the region’s competitive advantage, are the main contribution the growth of the Thai silk industry. The challenge of the industry is to create competitive advantage but not to lose the traditional heritage knowledge and skills of silk production. Therefore, the research examines the nature of silk production in relation to development of co-operative linkages for access to the flow of information for product and market development. The application of the value-chain model provides a framework for analysing actors and factors which influence the silk production in particular value-chains. This allows identification of livelihood resources of stakeholders that can be allocated in their value-chain environments. This also helps to identify strengths that might create competitive advantage and weaknesses that lead to exploit external resources. Analysis of these strengths and weaknesses assist integration of strategies which appropriately address improvement capabilities of stakeholders in particular value-chains. Research findings suggest that competitive advantage of the industry can be developed through specialization of silk production skills and product differentiation. Integration of strategies for improving capabilities of stakeholders in each value-chain is recommended. Personal network is used as an approach to facilitate strengthening existing linkages and developing new linkages between all silk stakeholders in the value-chains, as well as to gain access to the flow of information that is essential for product and market development. This is believed to promote sustainable livelihoods, sustainable development of the industry as well as facilitate regional economic growth.

description: MWCNTs were added to polyacrylamide (PAM) hydrogels in different proportions to tune their electrical and mechanical properties. The choice of MWCNTs as a reinforcement is justified by the fact that these are highly conducting, fairly stable and flexible particles. A series of MWCNT/PAM hydrogels were prepared by “freezing method”. The characteristic absorption peaks at 1480 and 1213 cm−1 in the FTIR spectra reveal that MWCNTs are embedded in the PAM hydrogels. Powder X-ray diffractograms and TGA thermograms show that the MWCNT/PAM hydrogels are crystalline, more thermally stable and have a higher electrical conductivity than a traditional PAM hydrogel. Scanning electron micrographs reveal about reduced pore size, homogeneous and denser texture. The swelling properties of all these hybrid hydrogels were found to be better than those of the parent PAM hydrogel. The Li-Tanaka equation was employed to produce the swelling parameters. The Dc of PAM hydrogel is 10 times higher than the literature value. 0.8% MWCNTs reinforced PAM hydrogel has excellent τc and electrical conductivity (0.76 mS/cm) with improvements in all properties. Lower Dc of 0.8% MWCNTs/PAM hydrogel reveal that extent of crosslinking is much important than density of the system for a better collective diffusion of the respective solvent.

Inflammation, oxidative stress and cardiovascular risk factors in Australian Aboriginal people
Creators: name: Shemesh, Tomer
Publisher: name: Charles Darwin University

description: C-reactive protein (CRP), semicarbazide-sensitive amine oxidase (SSAO)and the metabolic syndrome (MS) were assessed as risk markers of cardiovascular disease (CVD) in health screenings in remote Aboriginal communities. MS was prevalent among Aboriginal people; obesity was a driver of all MS components, including CRP in women but not in men. however, low HDL-C featured prominently, even in the lean. CRP identified 60% of the population at high CVD-risk and SSAO correlated positively with glucose metabolism, also confirmed in-vitro. Both CRP and SSAO were elevated with the MS. These observations suggested that conventional MS and obesity criteria may require knowledge of CVD end-points to be applicable in the population. SSAO may be useful to identify abnormal glucose metabolism and CRP appears promising as a CVD-risk marker. Further research is required to elucidate the relationship between inflammation, oxidative-stress and abnormal metabolism to curb the burden of CVD in this high CVD-risk population.

description: Introduction: Adrenocortical carcinoma (ACC) is a rare disease with a poor prognosis and limited therapeutic options. Aim: The aim of this study was to assess the anti-proliferative effect of combinatorial targeting of the PI3K/Akt/mTOR pathway with different drugs and simultaneous targeting of the MEK/Raf/ERKpathway in H295R adrenocortical cancer cells. Material and Methods: The cytotoxicity of LY294002 (pan-PI3K inhibitor), everolimus (mTOR inhibitor), BEZ235 (dual PI3K/mTOR inhibitor) and U0126 (MEK1/2 inhibitor) was assessed by Alamar blue assay in the H295R cell line. After finding the maximal cytotoxic concentrations for all inhibitors, we used suboptimal concentrations for experiments where multiple agents were used simultaneously. Everolimus and BEZ235 were kindly provided by Novartis, Switzerland; LY294002 and U0126 were commercially available. Results: While everolimus, BEZ235 and LY294002 caused 20±6%, 15.6±6% and 11±1% cytotoxicity when used as single agents, co-treatment of cells with everolimus and BEZ235 showed a synergistic cytotoxic effect of 54±9% (p=0.007) (the strongest effect for combination of two inhibitors in our system, N=3 independent experiments). Addition of LY294002 to everolimus and BEZ235 increased the effect further to 65±7%. We also explored the potential benefit of combined inhibition of PI3K/mTOR and MEK1/2. Addition of U0126 to BEZ235 had a synergistic effect (42±3% vs 14±5% and 15±5.6% alone, respectively, N=3 independent experiments). We observed only an additive effect if the MEK1/2 inhibitor was added to everolimus alone or in combination with BEZ235. Conclusions: The combination of agents inhibiting PI3K/Akt/mTOR and MEK/Raf/ERK pathways results in a synergistic cytotoxic effect. Our results suggest also that multiple mode of inhibition of the same pathway may result in a greater cytotoxic effect in adrenocortical cancer cells which cannot be achieved by simple dose escalation. We suggest that new combinations targeting those pathways require further investigation to improve the treatment of ACC patients.
