Migrants inside and outside Africa. Motivations, Paths and Routes
Authors: Varani Nicoletta , Bernardini Enrico
Published: December 2018

The phenomenon of migration has always existed during the history of man since the beginning of time, just think of the history of the diaspora of the Jewish people until the great migrations of the nineteenth century which involved several European peoples, including Italians, Germans, Poles, and non-Europeans, such as the Japanese, heading to North or South America.

This article, using official sources provided by IOM, UNHCR and other accredited international statistical sources, aims to offer a critical reflection about the motivations, routes and paths of migrants outside and inside Africa, showing that only a small part of them reach Europe.

In fact, the first attractive centre for internal migration is Côte d’Ivoire, one of the countries, together with Nigeria, which is the driving force behind the sparsely populated economy of West Africa, rich in agricultural raw materials (starting with cocoa and coffee).

Finally, particular attention is given to the Italian case because is the geographical area most affected by the landings of migrants. In fact, hostility towards migrants in Italy at the end of last year was on the increase: one Italian in two said he considered immigrants a danger and was afraid of it.
Africa: Risk, Security and Mapping of Human Rights Violations
Authors: Varani Nicoletta , Bernardini Enrico
Published: December 2018

Planetary interdependence makes the task of states and international organizations to guarantee security inside and outside national borders ever more urgent. The tendency is to widen the space from national to international and to conceive of security as multidimensional for the satisfaction of human needs, assumed as priority needs with respect to those of the States. The old concept of national security must today confront the new concept of human security cultivated within the United Nations, which places the fundamental rights of the individual and of people at the centre of attention and lays the foundations for overcoming the traditional politics of power.

The concept of human security emphasises the security of the individual and his protection from political violence, war and arbitrariness. It takes account of the strong correlation between peace policy, human rights policy, migration policy and humanitarian policy.

The contribution provides, through a series of social indicators such as the Global Peace Index (GPI), Corruption Perceptions Index (CPI) and the World International Security and Policy Index (WISPI), a framework on risk, security, human rights violations in the African continent and examines some significant case studies related to sub-Saharan Africa.
Nonlinear PD plus sliding mode control with application to a parallel delta robot
Authors: Boudjedir Chems Eddine , Boukhetala Djamel , Bouri Mohamed
Published: December 2018

In this paper, a hybrid nonlinear proportional-derivative-sliding mode controller (NPD-SMC) is developed for the trajectory tracking of robot manipulators. The proposed controller combines the advantage of the easy implementation of NPD control and the robustness of SMC. The gains of PD control are tuned on-line in order to increase the convergence rate, whereas the SMC term is introduced to reject the external disturbances without requiring to know the system dynamics. The stability of the NPD-SMC is proved using Lyaponuv theorem, and it is demonstrated that the tracking error and the tracking error rate converge asymptotically to zero. Experiments are carried out on the parallel Delta robot to illustrate the effectiveness and robustness of the proposed approach. It is also shown the superiority of the NPD-SMC control over the NPD control and PD-SMC control.

Authors: Marek Jan , Hospodka Jiri , Subrt Ondrej
Published: December 2018

This paper presents a dynamic part of the pump stage model of the cross-coupled charge pump. The complex model has been used for both the estimation of the N-stage pump properties in a wide range of the input parameters and derivation of equations for synthesis process, as the main capacitor sizing, which is also mentioned in the article. Dynamic part of the model (pump stage capacitances) is determined from Ward’s capacitance piece-wise model through the BSIM MOSFET model equations. Main capacitor and load capacitor sizing are based on the time response characteristics fulfilling the system behavior in time. Guideline on the MOS transistor sizing as the nonlinear main pump capacitor and specification of the diode transistor for the design process are also clarified. The characteristics of the proposed circuit have been verified in the professional design environment Mentor graphics and analysis algorithm based on the state-space description of the inner complex model was programmed in Maple SW. The main benefit is to offer the alternative way of the charge pump synthesis by using the complex model and symbolic description of all formulae to find the required pump parameters without long-time simulation process.
Performance optimization methods for switched-capacitor biquadratic filters
Authors: Nahlik Jiri , Hospodka Jiri , Sovka Pavel , Mullane Brendan , Subrt Ondrej
Published: December 2018

A class of computer-aided optimization methods based on Differential Evolution (DE), Particle Swarm Optimization (PSO) and Nelder Mead algorithms applied to a switched-capacitor (SC) filter circuit design are investigated. Comparisons of these algorithms applied to a 4th order biquadratic two-channel filter bank CMOS design on 0.35 µm technology are made. The frequency responses of the biquadratic filters must match ideal responses in a finite number of iterations with a limited number of “particles”. The original and derived methods are evaluated on the base of their convergence progress and their reliability over different starting populations. An optimal design approach based on combining algorithms is derived as a more suitable and more reliable method for SC circuit optimization.
Computing multiplicative inverses in finite fields by long division
Authors: Grošek Otokar , Fabšič Tomáš
Published: December 2018

We study a method of computing multiplicative inverses in finite fields using long division. In the case of fields of a prime order p, we construct one fixed integer d(p) with the property that for any nonzero field element a, we can compute its inverse by dividing d(p) by a and by reducing the result modulo p. We show how to construct the smallest d(p) with this property. We demonstrate that a similar approach works in finite fields of a non-prime order, as well. However, we demonstrate that the studied method (in both cases) has worse asymptotic complexity than the extended Euclidean algorithm.
The contribution of remote sensing in hydraulics and hydrology, analysis and evaluation of digital terrain model for flood risk mapping
Authors: Bouzahar Faiza hassainia , Ouerdachi Lahbaci , Keblouti Mahdi , Seddiki Akram
Published: December 2018

The study of flood risk involves the knowledge of the spatial variability in the characteristics of the vegetation cover, terrain, climate and changes induced by the intervention of humans in watersheds. The increased needs of the actors in land management mean that static maps no longer meet the requirements of scientists and decision-makers. Access is needed to the data, methods and tools to produce complex maps in response to the different stages of risk evaluation and response. The availability of very high spatial resolution remote sensing data (VHSR) and digital terrain model (DTM) make it possible to detect objects close to human size and, therefore, is of interest for studying anthropogenic activities. The development of new methods and knowledge using detailed spatial data, coupled with the use of GIS, naturally becomes beneficial to the risks analysis. Indeed, the extraction of information from specific processes, such as vegetation indices, can be used as variables such as water heights, flow velocities, flow rates and submersion to predict the potential consequences of a flood. The functionalities of GIS for cartographic overlay and multi-criteria spatial analysis make it possible to identify the flood zones according to the level of risk from the flood, thus making it a useful decision-making tool.

This study was carried out on the territory of watersheds in the Annaba region, East of Algeria. The choice was guided by the availability of data (satellites images, maps, hydrology, etc.) and hydrological specificities (proximity to an urban area). The adopted model is divided into two parts. The first part is to establish a methodology for the preservation of wetland biodiversity and the protection of urban areas against floods. Thanks to the multi-criteria spatial analysis and the functionalities of the GIS, we established a flood risk map for the watershed defined above. The result was satisfactory compared with the field reality. The second part of the model consisted of the integration of cadastral information with the flood risk map obtained in the first part of our research.

The primary objective of this mapping is to contribute to the development of flood risk management plans (in the sense of risk reduction). The mapping stage also provides quantitative elements to more accurately assess the vulnerability of a territory.
Regional frequency analysis of extreme precipitation in northeastern Algeria
Authors: Dad Soufiane , Benabdesselam Tamara
Published: December 2018

The aim of the study is to improve the quality of estimating of the annual maximum daily precipitations of the northeastern area of Algeria. The regional frequency analysis based on L-moments was used. The investigated area is represented by 58 measuring stations. The main stages of the study were the definition of homogeneous regions and the identification of the regional distribution. It has been defined that the study region is homogeneous in terms of L-moments ratios despite the climatic differences within the region. Among the different tested distributions; the generalised extreme value (GEV) distribution has been identified as the most appropriate regional distribution for modelling precipitation in the region. The growth curve, derived from the regional distribution, was established. Therefore, to estimate the different return period’s precipitation quantiles in a given site of the region, the mean precipitation of the site has to be multiplied by the corresponding regional quantile (growth factor). Comparison of the quantiles estimated from the regional and at-site frequency analysis showed that in the majority of stations (82.8%) at-site model underestimates the quantiles having high return periods.
Technological model of water contact iron removal

Published: December 2018

Different types of filters are used to remove iron from underground water, one of them is foam polystyrene. Depending on the chemical water composition, tasks for water supply and other working conditions of iron-removing filters, it is necessary to define an exact grain size, specific granulometric composition, the thickness of the layer and the adequate rate of filtration. This kind of problems is multifactorial and its solution is based on the mathematical modelling.

As a rule, two parallel processes considered during iron removal of underground water in filters: efficiency of water treatment and growth of head losses. Therefore, the model of water iron removal based on two main blocks, clarifying block takes into account the material balance and kinetics of the process; hydrodynamic block describes the dynamics of head loss in the granular loading. The kinetics of the detention of iron compounds in granular loading consists of two mutually opposite processes. With an increase of the amount of adsorption-catalytic precipitate, the rate of sorption of iron compounds and oxidation of ferric iron increases and the efficiency of iron-removing increases. On the other hand, with decreasing porosity of loading the true velocity of the fluid increases, that reduces the intensity of adhesion of iron compounds.

Developed mathematical model allows for determining optimal values of structural and technological parameters of iron-removing filters taking into consideration the specific filtering conditions.
Hydrochemical assessment and groundwater pollution parameters in arid zone: Case of the Turonian aquifer in Béchar region, southwestern Algeria
Authors: Mokeddem Ikram , Belhachemi Meriem , Merzougui Touhami , Nabbou Noria , Lachache Salih
Published: December 2018

Groundwater samples from Turonian aquifer of Béchar region were evaluated as drinking and irrigation water sources. physicochemical parameters including pH, EC, TH, Na+, Ca2+, Mg2+, Cl−, SO42– and NO3− were determined for 16 water sampling points. These characterizations show that the groundwater is fresh to brackish, slightly alkaline and the major ions are Na+, Ca2+, Mg2+, Cl− and SO42–. According to WHO standards, 50% of the analysed water are suitable as a drinking source while the other samples are not in compliance with drinking water standards. This non-compliance is basically due to the high concentrations of Na+, Cl−, and SO42– requesting further treatment to reach the stringent standards. According to the results of nitrate concentrations, anthropogenic source seems to influence the groundwater quality. The present study shows that Béchar groundwater may represent an important drinking and irrigation water source. However, a specific management strategy should be adapted in order to avoid the contamination by anthropogenic sources.
Analysis of principal components used for modelling changes in glacitectonically disturbed areas
Authors: Mrówczyńska Maria
Published: December 2018

Determination of vertical displacements of engineering objects is closely related to geodesic monitoring. Its purpose is to record the dynamics of changes in the deformation phenomenon. Geodesic monitoring requires the use of appropriate measurement equipment and appropriate methods for processing observation results, which make it possible to determine the correlation between the causes and effects of deformations in engineering objects. Progress in information technology resulted in the appearance of new methods for processing and compressing experimental data which are resistant to noise or interference and enable reduction of the amount of information.

The paper presents a method for statistical analysis of multidimensional data based on PCA (principal component analysis) transformation, implemented with the use of a neural network. PCA transformation, related to the Karhunen–Loeve transformation, is used for processing signals regarded as stochastic processes. This method makes enables reduction of the input data space on the basis of independent principal components with due attention to their significance. It also makes it possible to model changes occurring in both buildings and terrain in glacitectonically disturbed areas.

Authors: Kudlac Stefan , Gasparik Jozef , Dedik Milan , Kurenkov Petr V.
Published: December 2018

An effective functioning of logistic chains through the use of intermodal transport inevitably necessitates elimination of potential constraints, which have a negative impact on the logistic chains implementation. The objective of the contribution is the analysis, definition as well as classification of constraints related to the logistic chains in the intermodal transport, which should enable to compare levels of constraints in different alternatives of the logistic chain implementation. Based on the comparison of the restriction levels, it is possible to select a more convenient way of the logistic chain implementation. The defined relevant constraints are assessed using scientific methods. These identified constraints have formed the basis for establishing a methodology, which enables to determine weights of constraints as well as to compare their levels on the basis of specific needs of entities.

Counterfactual Histories of Moon Landing
Authors: Borowski Mateusz
Published: December 2018

The article is devoted to the analysis of chosen examples of counterfactual narratives which diverge from the typical alternative accounts of history written in the “what if” mode. It focuses on counterfactual representations of space flight and moon landing as crucial historical events of the 20th century. The point of departure for the text is provided by the New Historicist understanding of historical fact and historical event, with particular attention paid to Hayden White’s concept of metahistory. However, to identify the possible functions of the new counterfactuals, I go beyond the binary of past and present which lies at the core of White’s concept. To this end, I employ Jacques Derrida’s concept of artifactuality, which describes the process of the production of facts about current events. I apply this concept to analyse two examples of counterfactual films about space flight: the comedy Moonwalkers (dir. Alain Bardou-Jacquet, 2015) and a mockumentary First on the Moon (dir. Aleksey Fedorchenko, 2005). In these examples, I identify strategies of deconstruction of fact-making which Derrida recommended in his essay. In the concluding part, I introduce the third example of counterfactual narrative, which not so much deconstructs factuality but, rather, counteracts the process of cultural oblivion. In Hidden Figures (2016), Margo Lee Shetterly reconstructed the role that African-American women played in the space race, introducing them into the official historical narrative. In this case, I also compare the book with its cinematic rendition to argue that counterfactuals introduce a new model of thinking of collective relationship with the past.

La ecología urbana brinda directrices a las políticas de desarrollo urbano, para que las sociedades humanas vivan en ambientes más saludables y naturales. Las aves son buenas indicadoras de los ecosistemas naturales, por tal razón con el objetivo de determinar la relación de las plantas, clima y ruido con la biodiversidad de aves urbanas de la ciudad de Iquitos (Perú), se utilizó el método de conteo por puntos en seis de las principales plazas de la ciudad. El diseño de muestreo en cada plaza consistió de cuatro puntos de observación, y se colectó información durante tres días consecutivos, desde las 6:00 a 9:00 h y 16:00 a 18:00 h. La riqueza de aves fue de 50 especies, con mayor abundancia de Columba livia, Coragyps atratus y Tyrannus savana, y la riqueza de plantas fue de 19 especies, con dominancia de Adonidia merrillii, Elaeis oleifera, Livistona chinensis y Ficus benjamina. La temperatura ambiental entre las plazas no difieren, pero si la temperatura del suelo, humedad relativa y ruido. Hay relación del índice de abundancia de aves carnívoras con la riqueza de especies de plantas en general, plantas nativas y riqueza de árboles. La presencia de plantas, sobre todo de árboles altos proporcionaría mayor oferta de alimento, sitios de perchado y de nidificación a las especies de aves carnívoras. A mayor número de estas especies de aves en un ambiente urbano mayor será el avance hacia una ciudad verde.

Published: December 2018

Demir, toprakta en çok bulunan elementlerden bir tanesi olmasına karşın çözünürlüğü alkali topraklarda düşüktür. Dolayısıyla bu tür topraklarda yetişen bitkiler sürekli demir eksikliği stresine maruz kalırlar. Dünyadaki tarım arazilerin üçte biri bu tür topraklardan oluştuğundan dolayı tedavi edilemeyen demir eksikliği tarımsal üretimi kısıtlar. Bitkilerde gözlenen demir eksikliğinin tedavisinde farklı demir gübreleri kullanılmaktadır. Ancak, bu gübrelerin kullanımı üretim maliyetlerini artırmaktadır. Maliyetlerin azaltılabilmesi için bitkilerin toprakta bulunan demiri en etkin biçimde kullanabilmeleri gerekir. Bunun için de ilk olarak bitkilerin topraktaki demiri nasıl kök içerisine aldıklarının incelenmesi gerekmektedir. Son otuz yılda yapılan çalışmalarda farklı bitki gruplarının 3 farklı demir alım mekanizması kullandıkları keşfedilmiştir. Bu derlemenin amacı, demirin kök içerisine alımından sorumlu taşıyıcılar ile bu taşıyıcılar hakkındaki güncel gelişmelerden bahsetmektir.

Authors: Sağlam Coşkun , Önder Serpil
Published: December 2018

In this study, the usability of some herbaceous halophytes grown naturally in salt marshes that dry most of the year in Central Anatolia Region were investigated in landscape design. Within the scope of the research, in the years of 2016 and 2017, seasonal field studies were carried out in saline habitats in the vicinity of Konya, Ankara, Aksaray and Nevşehir, and taken photographs and herbarium samples of halophytic plant species. The general botanical and ecological characteristics of the selected species are given and the values used in landscape design have been determined considering the aesthetic and functional properties. As a result of the field studies carried out during the vegetation periods, 59 halophytic plant species, belonging to 38 genera and 19 families that could be used in landscape design were identified. The most representative family was the Asteraceae with 11 species, followed by Plumbaginaceae (9 species) and Chenopodiaceae (8 species). The genus Limonium from Plumbaginaceae family is well represented with 8 species for landscape use. The endemism rate of halophytes used in landscape design is 42% (25 species) in the research area. The most common uses in landscape design are determined in roof gardens by 49 species, followed in ground conservation and erosion prevention by 31 species. Since these halophytic species, which are mostly succulent and endemic, are well adapted into both wet and dry areas. Their use in landscape design is of great importance for restoration of arid and barren land, which may increase as a result of global climate change, conservation of biodiversity as well as sustainable agricultural practices.

The experiment was laid out in Randomized Complete block Design with three replications with 30 plots. Ten fertilizer treatments (T1= Compost, T2= Cow dung, T3= Poultry manure, T4= Recommended fertilizer dose, T5= Compost + Half recommended fertilizer dose, T6= Compost + Full recommended fertilizer dose, T7= Cow dung + Half recommended fertilizer dose, T8= Cow dung + Full recommended fertilizer dose, T9= Poultry manure + Half recommended fertilizer dose, T10= Poultry manure + Full recommended fertilizer dose. The recommended fertilizer dose was 500 Kg ha-1 urea + 250 Kg ha-1 TSP + 200 Kg ha-1 MP + 15 Kg ha-1 ZnSO4 + 6 Kg ha-1 Boric Acid. And the rate of Compost, Cow dung and Poultry manure was 10t/ha. The effect of different manure and fertilizer doses on the yield and yield attributes were significant. The plant height, number of leaves per plant, weight of stem per plant, weight of leaves per plant, length of cob, grain weight per cob, diameter of cob, no. of grains per row, no. of total grains per cob, 1000-grain weight, yield plant-1, yield ha-1 were significantly affected by different manures and fertilizer uses with different doses. The treatments T1, T2, T3, T4, T5, T6, T7, T8, T9 and T10 gave grain yield 10.16, 9.09, 8.49, 14.34, 13.35, 18.12, 11.99, 17.09, 11.40 and 15.98 t ha-1, respectively. The T6 Treatment gave higher grain yield (18.12) t ha-1 and the T3 treatment performed lowest grain yield (8.49 t ha-1). The application of compost and full dose fertilizer is higher yielding. Balance nutrition with enough organic matter enrichment of the soil is the cause of this result.

Published: December 2018

Türkiye‘de kırmızı et tüketiminin yaklaşık %90‘ını sığır eti oluşturmaktadır. Tüketim bazında ele alındığında sığır eti daha çok dana eti ile eş tutulmakta ve bu nedenle fiyat değerlendirmelerinde dana eti fiyatları yaygın olarak kullanılmaktadır. Dana eti fiyatlarındaki değişimin tüketim üzerinde oldukça etkin bir faktör olduğu bilinmektedir. Bu çalışmada dana eti fiyatlarındaki dalgalanmaların araştırılması amaçlanmıştır. 2005 Ocak- 2017 Aralık dönemini kapsayan süreçte dana eti fiyat belirsizliğinin tespitinde GARCH(1,1) modeli kullanılmıştır. Model sonucuna göre dana eti fiyatlarının ekonomik ve siyasi istikrarsızlık, gıda krizi, doğa olayları vb. herhangi bir şok karşısında büyük sıçramalar ile tepki verdiği ve dana eti fiyatlarının ortalama fiyata göre uzun bir zaman sürecinde normale dönebileceği tespit edilmiştir. Çalışmada, Türkiye‘de kırmızı et fiyatlarının istikrarlı bir yapı kazanmasına yönelik dış ticaret politikaları ile birlikte büyükbaş hayvancılığa ilişkin arz politikaları ile tamamlayıcı olarak küçükbaş arzını destekleyici politikaların geliştirilmesi gerektiği sonucuna varılmıştır.
N-Acyl Homoserine Lactone-Mediated Quorum Sensing System Inhibition of Phenolic Strawberry Extract
Authors: İlk Sedef
Published: December 2018

Phenolic compounds which have many bioactivities such as antioxidant, antimicrobial and also inhibition of quorum sensing-regulated violacein pigment production properties are one of the plant secondary metabolites. The objective of this study was to determine the antioxidant, antimicrobial activity and the inhibition of quorum sensing (QSI) activity by the phenolic extract obtained from strawberry fruits (Fragaria×ananassa cv. ‘Rubygem‘). The phenolic content of extract was determined as 3089 Î¼g GAE g fw-1. The antioxidant activity determined through the ABTS+ and FRAP method was 28.4 and 26.2 mmol TE L-1 respectively. The phenolic extract was able to inhibit all the evaluated bacteria by the disc diffusion assay in the range of 3.12–18.36 mm and could inhibit the quorum sensing phenomena in bacteria. The strawberry phenolic extract exhibited high antioxidant capacity, antimicrobial and anti-quorum sensing properties. To our knowledge, this is the first report on the quorum sensing inhibition activity of strawberry fruit extract. The discovery of non-toxic novel compounds within antibacterial and QSI activity could lead to the development of antimicrobial therapeutic agents that can be alternative and complementary treatments against antibiotic resistant bacterial pathogens

The purpose of this study is to compare innovative technology usage levels of dairy farms, supported and non-supported by The Instrument for Pre-accession Assistance-Rural Development (IPARD) program, by scoring their usage level of 10 innovative technologies in their dairy farms. Another purpose of the study is to determine the factors associated with the innovative technology usage levels of dairy farms. The main material of the study is dairy farms supported and not supported by the IPARD program in Konya. Full count sampling method was used when determining the dairy farms supported by IPARD Program and Neyman allocation sampling method was used when determining the dairy farm non-supported by IPARD program. Research data were collected from 50 dairy farms supported by IPARD program and 100 dairy farms non-supported by IPARD program by administering a questionnaire filled during the face-to-face interviews conducted with each individual respondent. As a result of the study, it was determined that the average gross production values and gross profits of dairy farms supported by IPARD program were 4 times higher than those non-supported by IPARD program. While innovative technology usage level of dairy farms non-supported by IPARD program were entirely low level, 90% of dairy farms supported by IPARD program were high level. From the point of view of dairy farm scale, it was determined that innovative technology usage levels were high (69.84%) in dairy farms that had 51 and more milking cows. As a result of chi-square independence test, statistically significant relationship was found between innovative technology usage level of dairy farm and 12 of 13 factors.

THE OUTSOURCING PROCESS CONSEQUENCES FOR MANAGEMENT OF HEALTH SERVICES SECTOR

ABSTRACT

The present study proposed the accomplishment of a bibliographic review with search and selection criteria used by the systematic review, having as main objective the identification of the effects arising from the process of outsourcing in the health services management sector. This was supported by studies on the subject, published in the MEDLINE and SciELO databases, where they underwent a selection process, resulting in a collection of 15 articles. Among the results found, it was observed that the evolution of the outsourcing process brought benefits of great relevance to the health field, mainly in relation to the reduction of the budgetary costs of several health units, favoring access to the users of health services and consequently promoting an improvement in the quality of care to this population. However, some studies have shown some flaws in the administrative sector that have led to the emergence of serious financial problems. Therefore, it is essential that preventive and monitoring measures be taken in order to avoid future setbacks.
Using Melanogenesis to Study Antioxidants
Authors: Vercruysse Koen , Brown Iesha , Summers Sha'Kendria
Published: December 2018

Building upon our research on the non-enzymatic synthesis of melanins, we explored the possibility that the reactions involved in the synthesis of melanins could serve as the basis for the study of and search for compounds with anti-oxidant properties. The synthesis of melanins can be achieved through air-mediated oxidation or through reactive-oxygen-species-mediated oxidation and can readily be monitored by the changes in color. In addition, a broad variety of different precursors can be used to generate melanins. Thus, using melanogenesis as the foundation for an anti-oxidant assay, one can evaluate the effects of potential anti-oxidants against air- or reactive-oxygen-species mediated oxidations and evaluate the consistency of the anti-oxidant effects when different precursors for melanogenesis are used.

Remote control of physiological functions with light offers the promise of unveiling their complex spatiotemporal dynamics in vivo, and enabling highly focalized therapeutic interventions with reduced systemic toxicity. Optogenetic methods have been implemented in the heart, but the need of genetic manipulation jeopardizes clinical applicability. This study aims at developing, testing and validating the first light-regulated drug with cardiac effects, in order to avoid the requirement of genetic manipulation offered by optogenetic methods. A M2 muscarinic acetylcholine receptors (mAChRs) light-regulated drug (PAI) was designed, synthesized and pharmacologically characterized. The design was based on the orthosteric mAChRs agonist Iperoxo, an allosteric M2 ligand, and a photoswitchable azobenzene linker. PAI can be reversibly photoisomerized between cis and trans configurations under ultraviolet (UV) and visible light, respectively, and it reversibly photoswitches the activity of M2 muscarinic acetylcholine receptors. We have evaluated in vitro photoresponses using a calcium imaging assay in genetically unmodified receptors overexpressed in mammalian cells. Furthermore, using this new chemical tool, we demonstrate for the first time photoregulation of cardiac function in vivo in wildtype frog tadpoles and in rats with a method that does not require genetic manipulation. Such a new approach may enable enhanced spatial and temporal selectivity for cardiovascular drugs.
