Published: July 2018

According to the received results, the organs of the immune system of quails represent anatomically diffused but strategically distributed protective network: central - situated in well-protected places (thymus, bursa cloacalis), and peripheral - situated at the border of the organism with the environment (glandula palpebral tertius, lymphoid cecal tonsil and lymphoid diverticulus) and on the routes of blood circulation (spleen). They are indicators that inform the immune system of the organism about the antigenetic diversity of the environmental microflora, that should be taken into account while planning anti-epizootical measures during vaccination of birds in order to create the immunity against infectious diseases.

Authors: Matyashova G N , Zaets V G
Published: July 2018

For the detection and identification of Candidatus Phytoplasma vitis Flavescence doree - the yellowing grape quarantine pest for the territory of Russia and Candidatus Phytoplasma solani Bois noir - pathogen of blackening crust grape was used one of the existing methods of diagnosis PCR in “real time” (RT-PCR). Matched to the fragment 16SrRNA gene species-specific primer systems were tested for false positive and false negative results for the detection of plant material in the above two phytoplasmas. According to the results of PCR in “real time”, it was determined that the studied pairs of primers allow the identification of target species phytoplasmas. Cross-reactions with other species phytoplasmas were not detected. Primers pairs do not give false positive reactions with gram-positive bacteria and some types of bacterial microflora grapes. The primer pairs and probes FDrt and BNrt can be used to detect and identify phytoplasmas - pathogens FD and BN in the regulated articles, as well as monitoring. RT-PCR method is considered to be relatively simple to implement and does not require time-consuming for the detection results.

La posibilidad combinatoria de nada:una consecuencia para universales inmanentes
Authors: Parra Paine Sergio Rodrigo
Published: July 2018

Este trabajo se centra en la posibilidad de concebir un Nihilismo Ontológico a partir del combinatorialismo de D. M. Armstrong, según lo han sugerido Efird y Stoneham, aunque presentando una estrategia alternativa al denominado ‘argumento de la sustracción’. Según los autores, es posible postular dicho nihilismo mediante las nociones de construcción y estado de cosas de totalidad. Sin embargo, tal hipótesis genera la consecuencia de admitir universales no instanciados en la teoría, es decir, platónicos. Esto último se opone a los requerimientos básicos que fundan la teoría combinatoria, donde ha de imponerse la concepción de universales que únicamente existen en sus instanciaciones. Por ende, asumir una concepción platónica en este ámbito supone un coste muy alto para un naturalismo combinatorio, según el cual sólo existe lo que se encuentra localizado espacio-temporalmente.
Sobre la división de la razón en Kant: la ruptura con el sistema de racionalidad absoluta
Authors: Labrador Montero Daniel
Published: July 2018

Este artículo se propone mostrar cómo la filosofía de Kant supone una ruptura con las filosofías basadas en un sistema de racionalidad absoluta, donde el elemento cumbre es la unidad de la razón. De esta forma, se tratará de subrayar las principales críticas del filósofo prusiano a las teorías cimentadas en la unidad de la razón y en el acceso directo a la realidad, así como también exponer la propuesta kantiana de una estructura racional formal unitaria, pero que consta de varios usos irreconciliables.
FORMAS DECALCANDO FORMAS: A MATERIALIDADE DO TRÁGICO
Authors: Araújo Bárbara Del Rio
Published: July 2018

Este trabalho pretende destacar a materialidade do fenômeno trágico a fim de entender a especificidade histórica desse elemento estético, ainda que muitas vezes a crítica e a filosofia o tenham associado ao destino humano, às forças ocultas e irracionalistas da natureza. A versatilidade dos gêneros literários e a tragicidade produzem significados culturalmente e são concretizações das relações sociohistóricas, forma base das diferentes áreas da vida espiritual. A sistematização do ponto de vista aqui abordado em torno do objeto contará com a referência teórica de Benjamin, Hegel e Lukács, cujo raciocínio implica em entender a totalidade das relações de produção da sociedade, a base real onde erige a superestrutura a qual corresponde formas definidas da vida social e intelectual. Nesse imbróglio, não é a poética dos gêneros ou a consciência dos homens que determinam a existência do trágico, mas a existência social que sobredetermina as suas diferentes configurações.

Authors: Lima Carmem Medeiros
Published: July 2018

O mito é uma história na esfera do sagrado que relata um acontecimento ocorrido in illo tempore sobre as façanhas dos entes divinos e sobre a existência da realidade que conhecemos. Dentro dessa realidade encontramos explicação para comportamentos humanos, para a origem e a finitude dos seres vivos ou não, para a organização da sociedade e do trabalho. A busca de modelos de verdade alcançam os narradores/escritores nas narrativas orais e escritas e o fascínio das figuras míticas atingem os leitores das mais diversas faixas etárias. Em uma delas, o público infantil e juvenil, analisaremos o mito da criação cristão e a forma como foi reatualizado a partir da identificação dos relatos cosmogônicos presentes na primeira narrativa escrita da obra As crônicas de Nárnia, de Clive Staples Lewis, tendo como apoio teórico os ensinamentos de Mircea Eliade.

O RESGATE E A SUBVERSÃO DO MITO HISTÓRICO EM O CONQUISTADOR, DE ALMEIDA FARIA
Authors: Lopes Lima Silvani
Published: July 2018

Este artigo é resultante de uma dissertação de mestrado, defendida em 2006. No presente texto, buscamos realizar uma análise da obra estudada sob dois aspectos: do resgate e da subversão de um mito histórico da cultura portuguesa, uma vez que o autor retoma a trajetória de Dom Sebastião e o nascimento do mito do sebastianismo para construir o seu protagonista e, ao mesmo tempo, faz a subversão disso quando propõe uma reencarnação do rei às avessas. Entre as conceituações teóricas que fundamentam essa leitura, trabalhamos com a ideia de mito enquanto ideologia, proposta por Roland Barthes, e com algumas formulações sobre ironia e paródia que Mikhail Bakhtin levanta na obra rabelaisiana, as quais julgamos aplicáveis ao contexto de nossa pesquisa. O texto de Faria apresenta um personagem em permanente crise identitária, que carrega o estigma de ser fisicamente idêntico ao famoso rei, mas possui uma personalidade bastante diversa da dele.

Published: July 2018

This study aimed to find out and comprehend (1) the formation of a civil partnership of notary in the implementation of the notary’s position: (2) the application of the principles of civil partnership stipulation in the Civil Code to civil partnership of notary. This research is a normative research that is a process to find out laws, legal principles, and legal doctrine to answer the legal problem. This study employed a statutory, comparison, and conceptual approaches. The results of this study indicate that: (1) the formation of civil partnership is not in line with the implementation of the notary position because the main purpose of the formation of civil partnership is to seek profit, while the obligation of the notary profession is to give priority to the society and the state. (2) the principles of civil partnership stipulation in the Civil Code differ from the principles of stipulation in the formation of notary civil partnerships, in the case of profit sharing. The form of civil partnership (Code Civil) applies profit sharing whereas in civil partnership of notary there is no profit sharing, but each notary receives honorarium in return for his services without any honorarium sharing. Therefore, a revision of the use of a civil partnership of notary term used in the Law of Notary Position is required

Emendation of the Grivska formation in its type area (Dinaridic Ophiolite Belt, SW Serbia)
Authors: Sudar Milan , Gawlick Hans-Jürgen
Published: July 2018

Age, microfacies and depositional realm of the Grivska Formation is
controversially discussed due to the fact that detailed investigations are
missing. Based on reinvestigations of the type locality of the Grivska
Formation and in adjacent areas, the following results can be drawn: 1) The
Grivska Formation is of Late Triassic (Early Carnian to Rhaetian) age
according to conodont dating. 2) Sedimentological and microfacies studies
evidenced that the Grivska Formation was deposited on the continental slope
and transitional to the Neo-Tethys Ocean. Based on the results of these
investigations in the type area and several reference sections in the
Dinaridic Ophiolite Belt, the Grivska Formation is emended and clearly
defined. In the Dinaridic Ophiolite Belt, the Grivska Formation occurs only
as clasts and blocks in the ophiolitic melange.
AR, CR and ARCR modeling for simulations and analyses of karst groundwater quality parameters
Authors: Ristic-Vakanjac Vesna , Cokorilo-Ilic Marina , Papic Petar , Polomcic Dusan , Golubovic Radisav
Published: July 2018

Although an invisible component of the hydrologic cycle, groundwater
generally takes precedence over other water resources in the area of
drinking water supply. Among groundwater resources, karst aquifers tend to
be rich in sufficiently-accessible amounts of high-quality water. During
most of the year, this water requires only disinfection prior to delivery to
the end user. However, in many cases extreme rainfall and/or sudden snow
melt results in transient turbidity, increase in bacterial count and
temporary contamination (e.g. increase in nitrate and phosphate
concentrations). To be able to determine the effect of the precipitation
regime on various groundwater quality parameters, it is necessary to
establish continuous monitoring of the parameter of interest and certain
parameters should be observed at least once a day, if not more often
(continuously). Such monitoring provides sufficiently long time-series of
the considered parameter, so that autocorrelation and cross-correlation
analyses can be undertaken and AR, CR and ARCR modeling used for simulations
and short-term forecasts. Apart from the theoretical background, the paper
presents a case study of the occurrence of nitrates at a karst spring called
?Banja? near the city of Valjevo, Serbia. A ten-year (1991-2000) timeseries
of the discharged volume of water was used in the study, as well as nitrate
concentrations recorded on a daily basis. In addition, daily precipitation
was gauged in the immediate vicinity of the catchment and the rainwater
chemically analyzed. The analyses included nitrate concentrations in
precipitation. The generated timeseries were used for autocorrelation and
cross-correlation analyses of nitrate concentrations in the Banja Spring
pool during the entire period of monitoring, as well as in one wet and one
dry year. The results are presented for all three cases, based on
simulations applying AR, CR and ARCR modeling.
Dynamic calibration of temperature sensors from light rays for transient measurement
Authors: Goswami Rishikesh , Kumar Rakesh
Published: July 2018

Measurement of transient heat fluxes in the applications involving very short duration of a heating environment which has been promised for the candidate by measurement of surface heating rates with thin film gauges (TFG). They are basically resistance temperature detectors having to measure in a very short duration of time. In the present study, a platinum based TFG has been fabricated and dynamically calibrated (radiation based) in the laboratory with a view to assessing the performance of platinum thin film gauges (PTFG) in the dynamic environment. These examinations are focusing to explore the probability of using TFG for small duration transient measurements with pure radiation mode of heat transfer. Radiation based heat flux is applied on the gauge by using the halogen bulb in a square box and its response is obtained through measured transient temperature. Subsequently, the surface heat fluxes are estimated by using radiation-based heat transfer. The purpose of this work is to statically calibrate each handmade heat transfer gauges by using quartz as substrate material deposited on platinum paste. This experiment has been carried out by oil bath based experimental technique. The similar experimental environment is also studied to observe the transient temperature response by using numerical simulation. The experiments are carried out by exposing the platinum TFG to various known step heat load of known input wattage, for the duration of 10 seconds. Then, the voltage signals are recorded due to change in temperature of air-flow past the TFG. The numerical simulation (ANSYS-Fluent v. 14.5) is performed in the similar experimental environmental conditions, for the same heating loads. Experimentally recorded temperature signals from the gauges are compared with simulated temperature histories obtained through finite element analysis. Cubic spline methods of the 1-D heat conduction equation are used to predict surface heat flux and compared with input heat loads. The presently developed calibration set-up is seen to very useful for radiation-based measurements of TFG.
The thermal behavior of rammed earth wall in traditional house in Vojvodina: Thermal mass as a key element for thermal comfort
Authors: Lovec Vesna , Jovanovic-Popovic Milica , Zivkovic Branislav
Published: July 2018

The conducted research examines the thermal behaviour of the rammed earth walls, which is the basic structural and fa?ade element of traditional Vojvodina house. The traditional rammed earth house represents an important part of the total building stock of Vojvodina. Earth is a locally available, cheap, natural, environmentally friendly building material and has been used extensively for traditional family houses in Vojvodina. It has ecological and ?green? characteristics, which can be assessed as very high quality, and they are of significant importance in the context of sustainable development and striving to reduce energy consumption today. The research examines thermal behaviour of rammed earth wall, including theoretical analysis of: the heat transfer coefficient, U, the thermal resistance, R, and thermal conductivity, ?. One of the basic elements of thermal behaviour, the thermal mass, has been analyzed both theoretically and by measuring in situ. The in situ measurements were conducted on the traditional house in Vojvodina by measuring inside and outside surface wall and air temperature in summer. Analyses of rammed earth wall thermal performances have shown that the wall has low thermal conductivity, high heat capacity and significant thermal mass effect which is the key element enabling thermal stability. The research indicates rather good thermal properties of the rammed earth walls. Potential of rammed earth wall in Vojvodina should be an issue of further analysis, although the possibility of improvement of existing facilities to meet current standards in terms of energy efficiency should be considered.

Published: July 2018

Altering the surface cover of an area causes the change in the environment. By erecting buildings change in the flow of energy and matter through the urban ecosystems occurs creating multiple environmental problems. Built areas exert considerable influence over their local climate, amplifying problems such as heat waves, air pollution, and flooding. Greening the building envelope these problems can be partially mitigated. By combining nature and built areas in their designs, architects and urban planners can respond to these serious human health and welfare issues and restore the environmental quality of dense urban areas. Green living systems are not the only solution for new designs. Retrofitting existing buildings by altering the buildings' surficial properties can reduce buildings' energy consumption in case of older buildings with poor existing insulation. Implementation of green living systems in the building envelope, greening horizontal surfaces with intensive and extensive green roofs or using vegetation in vertical greening systems for fa?ades, is a strategy that provides ecological, economic, and social benefits. This review paper presents collected evidence of effects and explores the important role that the green living systems can play in the dense urban areas. Benefits such as heat island amelioration, reduction of buildings energy consumption, air quality and indoor and outdoor comfort conditions improvement, stormwater management and improved water run-off quality, will be mainly considered.

Authors: Andric Snezana , Jovanovic-Popovic Milica , Macut Nikola
Published: July 2018

Using RES is one of the most important characteristics of the sustainable and resilient development. Nowadays, need to minimize CO2 emissions is obligatory, especially in the sector of urban and architectural planning, since in Serbia approximately 50% of produced energy is spent in buildings. The CO2 emission, in urban structures, can and must be reduced at the different levels: building level, block, and city level. For the city of Kragujevac, based on urban parameters defined in General Urban Plan, typical urban block was chosen and typical building structure developed. Calculation were made, based on recommendations developed by the Ministry of mining and energy and Serbian regulations, for the energy needed for domestic hot water preparation. In this paper, the influences of architectural and urban parameters on the use of solar thermal collectors at the typical building and urban block level is investigated. Recommendations are prepared for principles of urban and architectural design in order to enable the use of collectors for domestic hot water preparation and in that way CO2 emission reduction. Developed methodology for the city of Kragujevac can be applied in defining design principles in whole the country and Balkans region, not only for the use of solar thermal collectors but also for the use of other RES.
Possibilities for the use of geothermal energy in new residential buildings in Serbia, case study: Urban blocks in city of Kragujevac
Authors: Macut Nikola , Jovanovic-Popovic Milica , Andric Snezana
Published: July 2018

Use of RES is an important element for achieving ambitious results for CO2 emission reduction in EU, emphasized and obligated by RES Directive, among other documents. In Serbia, as a candidate country and a signatory of Energy treaty, targets set by relevant documents reflect in benchmarks set by National Action Plan for Energy Efficiency, setting the level of reduction of energy consumption until 2018 for 9%, with more ambitious projections up to 2030. This calls for extensive research of possibilities for the use of renewable energy in buildings, its potentials and possible restrictions. Since the Directive states that low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby, an investigation of possibilities for application of geothermal ground probes for a typical residential urban block in the city of Kragujevac is present-ed. This enables analysis of limitations imposed by legal and physical conditions: planning guidelines, type of ground, functional requests and infrastructural capacities. Typology of characteristic urban block layouts for residential buildings is generated, leading to projections of possible area covered with ground probes and calculations of relevant energy needed for heating, based on current regulations on energy efficiency in buildings. From these calculations, percentage of defined energy needs from possible geothermal ground probes is defined, enabling estimation of geothermal energy potential for new residential building blocks.
A solar air-cooled high efficiency absorption system in dry hot climates: Reduction of water consumption and environmental impact
Authors: Marcos Jose , Lizarte Raquel , Varela Fernando , Palacios-Lorenzo Maria , Blanco-Marigorta Ana
Published: July 2018

A solar cooling system with an optimized air-cooled double-effect water/LiBr absorption machine is proposed as a sustainable alternative to meet cooling demands in dry hot climates. This system allows eliminating the cooling towers in those regions of the planet where water is scarce. This work analyses the environmental benefits of this air-cooled system, as well as its environmental foot-prints, compared to a solar water-cooled single effect. In this regard, a methodology has been applied to calculate the annual saving in water consumption produced in a case study: a hospital located in Almer?a, in South of Spain. Further-more, the reduction in energy consumption and CO2 emissions is also quantified since this machine can be driven by solar energy and with higher efficiency than those of single effect.

Authors: Baptista Nishida , Krambeck Larissa , Dias Dos , Antonini Alves
Published: July 2018

This work presents the use of electrical discharge machining (EDM) technology for manufacturing of three different types of axial microgrooves in heat pipes. This specific process, called wire electrical discharge machining (wire-EDM), allows the fabrication of microgrooves on the inner wall of a heat pipe with accuracy. Different from other capillary structures, such as composite wick and screen mesh, the material is removed from the pipe?s container in order to conceive the capillary structure, which contributes with the mass reduction of the passive two-phase heat transfer device. The heat pipes were manufactured from a straight copper pipe with the external diameter of 9.45 mm, the inner diameter of 6.20 mm, and a total length of 200 mm. Three types of axial microgrooves were manufactured for constant width (35 ?m) and varying the depth (from 30-48 ?m), and thickness (from 35-70 ?m). The number of microgrooves was also varied from 21-32 microgrooves. Water was used as the working fluid and the loading filling ratio was 60% of the evaporator volume. The condenser was cooled by air forced convection, the adiabatic section was insulated and the evaporator was heated by an electrical resistor and it was insulated from the environment with aeronautic thermal insulation. The thermal performance of the heat pipes are analyzed based on experimental results, so the heat pipes were tested at the horizontal and different inclinations under different low heat loads (from 5-50 W or a heat flux from 0.21-2.10 W/cm2). The experimental results showed that the axial microgrooves manufactured by the wire-EDM process worked satisfactorily in all analyzed cases and microgrooves of Type 1 showed a better thermal performance when compared with the others.
Numerical assessment of brick walls` use incorporating a phase change material towards thermal performance in buildings during a passive cooling strategy
Authors: Younsi Zohir , Naji Hassan
Published: July 2018

The integration of new building materials incorporating phase change material (PCM) into the building envelope leads to an increase of the heat storage capacity, which may have an influence on minimizing the cooling demand and heating of the building. This work addresses a thermal performance enhancement of brick walls with incorporated PCM. The improvement has been assessed through a numerical approach in dealing with a 1-D transient conduction problem with phase change, while leaning on experimental results from a transient guarded hot plates method. The simulations have been fulfilled using a hybrid method combining both the finite volume method and an enthalpy porosity technique. The results of this combined approach are in good agreement. In the light of the findings obtained, it appears that PCM incorporation into a brick masonry can both reduce peak temperatures up to 3?C and smooth out daily fluctuations. Thereby, the evaluation achieved can turns out useful in developing brick walls with an incorporated PCM for passive cooling, thus improving buildings thermal performance.

Authors: Arshi Banu , Sudharsan N.M.
Published: July 2018

Vapour absorption systems are more viable technology option in energy and environmental perspective in cooling and heating applications. Among the four major components of vapour absorption system, the absorber plays a vital role in deciding the performance, size and cost. Horizontal falling film absorbers comparatively contain good heat and mass transfer characteristics than other type of absorbers for working fluids such as water-lithium bromide. Literature shows that experimental approach of performance evaluation of absorber is more realistic and accurate than the theoretical approach. Hence in the present work, a detail experimental study has been done on horizontal tube falling film absorber using water-lithium bromide as a working fluid. The set-up consists of two major components viz. absorber and generator. Absorber contains three columns of tubes, with eight rows in each column. Detailed parametric study has been done by considering influence of spray density, cooling water-flow rate, cooling water temperature and concentration on solution temperatures, cooling water temperatures, inlet and outlet concentrations, heat flux, mass flux, heat transfer coefficient, and mass transfer coefficient with the help of plots. Results have been validated and literature gaps have been discussed.

Published: July 2018

A direct injection compression ignition engine fueled by diesel blended with 10% or 30% mass proportion of 2-methylfuran was experimentally studied. The in-cylinder combustion pressure, regulated emissions and particulate matter emissions at different pilot injection timings and masses were investigated under the exhaust gas re-circulation mode. It was found the blending with methylfuran increased the peak in-cylinder pressure and retarded the combustion phase at different pilot injection timings. The addition of 30% methylfuran increased the peak in-cylinder pressure and heat release rate gradually along with the advancement of pilot injection timing. The NOx, HC, and CO emissions increased with the advancement of pilot injection timing when the pilot injection proportion was fixed at 20%, and the blending with methylfuran reduced HC and CO emissions but increased NOx emissions considerably. The 30% methylfuran addition could significantly reduce nucleation mode and accumulation mode particles at different pilot injection timings and masses compared with pure diesel. In addition, the particulate mass con-centration of 30% methylfuranaddition remained at very low levels under all experimental conditions.

Extracellular ATP (eATP) activates T cells by engaging the P2X7R receptor. We identified two loss-of-function P2X7R mutations that are protective against type 1 diabetes (T1D) and thus hypothesized that eATP/P2X7R signaling may represent an early step in T1D onset. Specifically, we observed that in patients with newly diagnosed T1D, P2X7R is upregulated on CD8+ effector T cells in comparison with healthy control subjects. eATP is released at high levels by human/murine islets in vitro in high-glucose/inflammatory conditions, thus upregulating P2X7R on CD8+ T cells in vitro. P2X7R blockade with oxidized ATP reduces the CD8+ T cell–mediated autoimmune response in vitro and delays diabetes onset in NOD mice. Autoreactive CD8+ T-cell activation is highly dependent upon eATP/P2X7R-mediated priming, while a novel sP2X7R recombinant protein abrogates changes in metabolism and the autoimmune response associated with CD8+ T cells. eATP/P2X7R signaling facilitates the onset of autoimmune T1D by fueling autoreactive CD8+ cells and therefore represents a novel targeted therapeutic for the disorder.

Stress-related changes in β-cell mRNA levels result from a balance between gene transcription and mRNA decay. The regulation of RNA decay pathways has not been investigated in pancreatic β-cells. We found that no-go and nonsense-mediated RNA decay pathway components (RDPCs) and exoribonuclease complexes were expressed in INS-1 cells and human islets. Pelo, Dcp2, Dis3L2, Upf2, and Smg1/5/6/7 were upregulated by inflammatory cytokines in INS-1 cells under conditions where central β-cell mRNAs were downregulated. These changes in RDPC mRNA or corresponding protein levels were largely confirmed in INS-1 cells and rat/human islets. Cytokine-induced upregulation of Pelo, Xrn1, Dis3L2, Upf2, and Smg1/6 was reduced by inducible nitric oxide synthase inhibition, as were endoplasmic reticulum (ER) stress, inhibition of Ins1/2 mRNA, and accumulated insulin secretion. Reactive oxygen species inhibition or iron chelation did not affect RDPC expression. Pelo or Xrn1 knockdown (KD) aggravated, whereas Smg6 KD ameliorated, cytokine-induced INS-1 cell death without affecting ER stress; both increased insulin biosynthesis and medium accumulation but not glucose-stimulated insulin secretion in cytokine-exposed INS-1 cells. In conclusion, RDPCs are regulated by inflammatory stress in β-cells. RDPC KD improved insulin biosynthesis, likely by preventing Ins1/2 mRNA clearance. Pelo/Xrn1 KD aggravated, but Smg6 KD ameliorated, cytokine-mediated β-cell death, possibly through prevention of proapoptotic and antiapoptotic mRNA degradation, respectively.

Emerging evidence supports the importance of ghrelin to defend against starvation-induced hypoglycemia. This effect may be mediated by inhibition of glucose-stimulated insulin secretion as well as reduced insulin sensitivity. However, administration of ghrelin during meal consumption also stimulates the release of glucagon-like peptide 1 (GLP-1), an incretin important in nutrient disposition. The objective of this study was to evaluate the interaction between ghrelin and GLP-1 on parameters of glucose tolerance following a mixed-nutrient meal. Fifteen healthy men and women completed the study. Each consumed a standard meal on four separate occasions with a superimposed infusion of 1) saline, 2) ghrelin, 3) the GLP-1 receptor antagonist exendin(9-39) (Ex9), or 4) combined ghrelin and Ex9. Similar to previous studies, infusion of ghrelin caused glucose intolerance, whereas Ex9 had a minimal effect. However, combined ghrelin and Ex9 resulted in greater postprandial glycemia than either alone, and this effect was associated with impaired β-cell function and decreased glucose clearance. These findings suggest that in the fed state, stimulation of GLP-1 mitigates some of the effect of ghrelin on glucose tolerance. This novel interaction between gastrointestinal hormones suggests a system that balances insulin secretion and glucose disposal in the fed and fasting states.
