Gardeners’ Perceptions of Northwestern U.S. Native Plants Are Influenced by Ecological Information and Garden Group Affiliation
Authors: Anderson Aaron G. , Messer Isabella , Langellotto Gail A.
Published: June 2021

Plantings of native flowers are often installed to increase the pollinator habitat in urban and suburban gardens. However, in many regions, it is not known which native plants are best used for pollinator plantings in gardens. Candidate plants must be attractive to pollinators, but they also must have attributes that gardeners find appealing. To identify native plants that are attractive to gardeners, we disseminated two surveys. The first asked gardeners to use a 5-point Likert scale to rate how likely they would be to garden with 23 flowering plants native to the Pacific Northwest United States. The second survey asked gardeners to use a 5-point Likert scale to rate how likely they would be to garden with a subset of 11 of these 23 native plants before and after receiving information about each flower’s attractiveness to bees (Anthophila). Using the first survey, we found a high level of acceptance of native plants by home gardeners (6 of 23 flowers had a mean “likelihood of planting” score of ≥ 4). Additionally, gardeners stated their likelihood of planting these native species increased significantly after receiving information about the bees associated with each plant. Across both surveys, gardeners who identified as “native plant gardeners” stated they would be significantly more likely to garden with all native plant species. Both surveys included an opportunity to share open-ended comments, which revealed that gardeners were most concerned with flower aesthetics and the aggressiveness of growth. Gardeners felt most positively about flower aesthetics and beneficial ecological traits. Many gardeners also commented that they needed more information or were unfamiliar with the plants. This study shows that native plants can have high baseline appeal to home gardeners. Specifically, we identified five native plant species that northwestern U.S. nurseries might consider growing and marketing as pollinator plants because of their high level of attractiveness to bees and home gardeners: globe gilia (Gilia capitata), california poppy (Eschscholzia californica), douglas aster (Symphyotrichum subspicatum), oregon sunshine (Eriophyllum lanatum), and common yarrow (Achillea millefolium).

Published: June 2021

Mechanical stimulation to produce stable and high-quality crops under greenhouse conditions is a promising alternative to chemical growth retardants. However, plant tissue damage and the lack of full automatization have been major constraints for large-scale applications. We demonstrate the potential of automated, touch-less, directed air stream application systems to control the plant height and appearance of bellflower (Campanula ‘Merrybell’), creeping inchplant (Callisia repens), and tomato (Solanum lycopersicum ‘Romello’). Plants were cultivated under greenhouse conditions and exposed to regulated air stream stimuli by three different prototype systems. Air stream stimuli of all three prototype systems significantly reduced plant height of all three plant species. Bellflower plants showed a reduction of 24% and tomato plants showed reductions of 26% to 36% compared with the respective control plants. The degree of height growth inhibition in tomato was shown to be predominantly influenced by the stimulus intensity. An air pressure prototype system was successfully implemented in a horticultural company and the height of creeping inchplant could be sufficiently reduced by 20%, on average, throughout 1 year of the experiment compared with untreated controls. Overall, no plant tissue damage of plants treated with the air stream was visible, and no difference in the number of flowers of the bellflower plants treated with the air stream and of the untreated controls was observed.

Published: June 2021

The NAC (NAM, ATAF1/2, and CUC2) family is a group of plant-specific transcription factors that have vital roles in the growth and development of plants, and especially in fruit and kernel development. This study aimed to identify members of the NAC gene (PsNACs) family and investigate their functions in siberian apricot (Prunus sibirica). A total of 102 predicted PsNAC proteins (PsNACs) were divided into 14 clades and the genes were mapped to the eight chromosomes in siberian apricot. The PsNACs of the same clade had similar structures. A synteny analysis showed that the PsNACs had close relationships with the NAC genes of japanese apricot (Prunus mume). An expression pattern analysis of the PsNACs revealed many differences in various tissues and at different stages of fruit and kernel development. All eight PsNACs in clade XI have crucial roles in fruit and kernel development. Seven PsNACs (PsNACs 18, 64, 23, 33, 9, 4, and 50) in clades I, III, VI, VII, and XIII are related to fruit development. Eight PsNACs (PsNACs 6, 13, 46, 51, 41, 67, 37, and 59) in clades I, II, V, VIII, and XIII are involved in fruit ripening. Five PsNACs (PsNACs 6, 94, 41, 32, and 17) in clades I, IV, V, VII, and XI regulated the rapid growth of the kernel. Four PsNACs (PsNACs 50, 4, 67, and 84) in clades I, III, V, and XIII affected the hardening of the kernel. Four PsNACs (PsNACs 17, 82, 13, and 51) in clades II, XI, and IX acted on kernel maturation. We have characterized the NAC genes in siberian apricot during this study. Our results will provide resources for future research of the biological roles of PsNACs in fruit and kernel development in siberian apricot.

La construcción de pueblo en el populismo. Análisis al discurso de un presidente en Colombia (2002 - 2010)
Authors: Molina Javier A. , Blandón Laura C.
Published: June 2021

El objetivo de este artículo es presentar un análisis sobre las categorías que enmarcan la construcción de pueblo en el populismo, presentes en el discurso político del expresidente Álvaro Uribe Vélez. La metodología se fundamenta en la aplicación del método descriptivo multidimensional y en el análisis estadístico de datos textuales. Se trabajan 65 discursos emitidos por el líder político colombiano durante su período presidencial 2002-2010. Los resultados se soportan sobre la base de tres categorías propuestas por la teoría de la hegemonía como enfoque para el análisis político. La evidencia empírica referente de análisis son las palabras de mayor repetición que incentivaron la construcción de bandos dentro de la sociedad colombiana y la nominación de las políticas de gobierno desprendidas de esta relación. La pertinencia e innovación del estudio se fundamenta en su intensión de aportar nuevas herramientas metodológicas al populismo como fenómeno de análisis para la ciencia política y el conjunto de las disciplinas sociales en Colombia y América Latina.

O novo status do saber na era tecnológica e os desafios para a educação segundo Hans Jonas
Authors: De Oliveira Jelson Roberto
Published: June 2021

O objetivo do presente artigo é analisar a mudança no estatuto do saber a partir da era moderna e suas repercussões sobre a educação no século vinte um, tendo como referência a filosofia de Hans Jonas. Para tanto, analisaremos como o conhecimento perdeu seu valor contemplativo, ontológica e politicamente falando, para assumir uma perspectiva de exploração do mundo, chegando a apresentar-se ele mesmo como uma mercadoria, na forma da informação. Contrapõe-se, assim, o homo faber ao homo sapiens, com o prejuízo do segundo. À educação cabe enfrentar a tensão entre o fazer e o saber, recusando uma visão simplista da ideia de competências e assumindo uma posição crítica capaz de preparar o ser humano integralmente para assumir a sua responsabilidade diante dos novos poderes da tecnologia.

Usos e significados de “self” e “identidade” em Mind, Self and Society
Authors: Gonçalves Neto José Umbelino , Ferreira de Lima Aluísio
Published: June 2021

O presente artigo apresenta uma análise dos conceitos de “self” e “identidade”, identificando seus usos, significados no clássico Mind, Self and Society (1934), do psicólogo social George Herbert Mead. O método utilizado tomou como base a apropriação do pensamento de Ludwig Wittgenstein sobre a linguagem, como as palavras ganham seus significados e como lidar com problemas conceituais. Assim, foi realizado um levantamento sistemático de todos os casos em que Mead empregou os referidos conceitos no livro, seguido de uma descrição desses conceitos e de sua rede conceitual. A análise permitiu elucidar sinonímias, confusões e sobreposições de sentido entre “self” e “identidade” no texto do autor, além de esclarecer as relações desses conceitos com outros da teoria de Mead. A relevância dessa análise está na possibilidade de sanar ou prevenir confusões conceituais no uso desses conceitos em outras teorias influenciadas por Mead.

DESIGUALDADE ECONÔMICA E DIREITOS POLÍTICOS NA TEORIA DA JUSTIÇA DE RAWLS: UMA ANÁLISE A PARTIR DE THOMAS SCANLON
Authors: Guimarães Sandra Suely Moreira Lurine , Guimarães Heitor Moreira Lurine
Published: June 2021

O presente artigo pretende problematizar a maneira como a questão das desigualdades socioeconômicas e dos direitos políticos são tratadas na teoria da justiça originalmente formulada por John Rawls. Sabe-se que Rawls, na década de 1970, revolucionou os debates sobre justiça distributiva com a formulação da teoria que ficou conhecida como equidade, que se baseia na proposição de dois princípios de justiça, o primeiro tendo prioridade em relação ao segundo, destinados a reger a estrutura básica da sociedade. Muito recentemente, contudo, uma série de desafios teóricos à tradição liberal igualitária, da qual Rawls é um grande expoente, foi lançada por Thomas Scanlon, em sua proposta de atribuir à igualdade um valor intrínseco. O objetivo deste trabalho é mostrar como uma das questões levantadas por Scanlon, concernente à questão da participação política, pode ser capaz de comprometer seriamente a proposta original de Rawls de tal forma que a distribuição indicada como justa pelos próprios princípios acabaria por quebrar a prioridade estabelecida entre eles. Primeiramente, faremos um estudo sistemático de como Rawls elabora seus dois princípios de justiça e qual o lugar da igualdade dentro deles, com ênfase para os elementos relevantes para a análise posterior. Em seguida, tentaremos demonstrar, a partir do ponto de vista oferecido por Scanlon, como é possível encontrar em Rawls uma tensão entre a garantia de igual direito de participação política a todos, de um lado, e a permissão de desigualdades socioeconômicas, de outro.
Determination of Binding Potential of HCV Protease Inhibitors Against to SARS-CoV-2 Papain-like Protease wtih Computational Docking
Authors: Çalışkaner Zihni Onur
Published: June 2021

Background:

SARS-CoV-2, a novel coronavirus that caused a pandemic respiratory disease,
has recently emerged from China. Since it is a life-threatening virus, investigation of curative
medications along with protective vaccines still maintains its importance. Drug repurposing is a reasonable
and immediate approach to combat SARS-CoV-2 infection by identifying inhibitory molecules
from marketed drugs. PL protease (PLpro) is one of the essential enzymes for the progression of
SARS-CoV-2 replication and life cycle.

Objective:

We aimed to investigate the potential of 4 HCV protease inhibitors as probable repurposing
drugs in Covid-19 treatment.

Methods:

In order to understand possible binding affinity of HCV protease inhibitors, Boceprevir,
Grazoprevir, Simeprevir, and Telaprevir, against PLpro, we performed docking analysis in silico.
Docking study was accomplished using AutoDock 4.2 Software. Potential druggable pockets on
PLpro were predicted by DoGSiteScorer tool in order to explore any overlapping with binding regions
and these pockets.

Results:

This analysis demonstrated Boceprevir, Grazoprevir, Simeprevir and Telaprevir interacted
by PLpro with binding energies (kcal/mol) of -4.97, -4.24, -6.98, -1.08, respectively. Asn109, one of
the interacted residues with both Boceprevir and Simeprevir, is a neighbouring residue to catalytic
Cys111. Additionally, Telaprevir notably interacted with catalytic His272 in the active site.

Conclusion:

Present study explains the binding efficiency and repurposing potential of certain HCV
protease inhibitors against to SARS-CoV-2 PLpro enzyme. Docking sites and potential druggability of
ligands were also crosschecked by the estimation of druggable pockets. Thereby our results can promote
promising preliminary data for research on drug development in the fight of Covid-19.

Authors: Hussein Samia , Youssef Amal M. , Mohamed Dalia A. , Abdullah Doaa M. , Abdelrahman Shaimaa A.
Published: June 2021

Background:

Diabetes mellitus (DM) affects the musculoskeletal system through its
metabolic perturbations. Exercise modulates blood sugar levels and increases the body’s sensitivity
to insulin in patients with DM.

Objective:

This study aimed to investigate the potential effects of combined quercetin and coenzyme
Q10 (CoQ10) supplements with or without exercise on the histological, biochemical and
molecular structures of diabetic rat’s skeletal muscle.

Method:

A total of 64 adult male albino rats were divided into six groups: control, trained nondiabetic,
non-trained diabetic, diabetic rats treated with combined CoQ10 and quercetin, diabetic rats
with treadmill training, and diabetic rats treated with treadmill training and CoQ10 and quercetin.
Blood and skeletal muscle samples were obtained from all groups for routine histological examination
and biochemical determination of cytokine levels and protein activities. Quantitative real-time
polymerase chain reaction (qRT-PCR) and morphometric analysis of PAS and Bax expressions
were also performed.

Results:

Biochemical analysis revealed improvement in all studied parameters with combined Co-
Q10 and quercetin than exercise training alone. Combined treatment and exercise showed significant
improvement in all parameters especially interleukin 6 and malondialdehyde. Fibronectin type
III domain-containing protein 5 (FNDC5) expression and irisin levels increased in all trained
groups but combined treatment with exercise significantly increased their levels than exercise
alone. Histological analysis revealed improvement after exercise or combined treatment; however,
when exercise was combined with CoQ10 and quercetin, marked improvement was observed.

Conclusion:

the combination of CoQ10 and quercetin could be promising in preserving musculoskeletal
function in patients with DM concomitantly with physical exercise.

Published: June 2021

Friction welding is a welding technique that utilizes heat due to surface friction between a rotating and pressing workpiece. This study aims to analyze the effect of environmental temperature variations on the mechanical properties of Al 6061 alloys, friction welding specimens with variations in room temperature (27ºC), 50 ºC, 75 ºC, 100 ºC, 125 ºC, and 150 ºC. Welding is carried out using a lathe with a rotation speed of 1600 rpm, a workpiece diameter of 15 mm, a champer angle of 15º, a friction force of 65 bar for 6 seconds, and a final compressive force of 325 bar for 60 seconds. Changes in mechanical properties in terms of tensile strength and hardness. The results showed that the higher working environment temperature produced greater tensile strength than Al 6061 friction weld joints. From macro-micro observations, it was found that specimens with large tensile strength (specimens welded at 100 ºC, 125 ºC, and 150 ºC) had a large area (Zpl) and finer granules when compared to specimens with small tensile strength (specimens welded at room temperature (27 ºC), 50 ºC and 75 ºC).

Published: June 2021

The addition of bio-additive in gasoline was needed in order to improve the anti-knock quality. The bio-additive used was orange peel in the form of essential oil. Nevertheless, it make any changes of fuel properties affecting standard compliances: physical properties, engine performances and exhaust gas emissions due to some main compound effects of orange oil; limonene up to 90%. The recent study aimed to analyze the blends of bio-additives and premium gasoline  experimentally related to improve the fuel properties theoretically. By verifying the blends, they were tested at blending concentration ratio from 1% to 75%. For each blend, the physical properties; kinematic viscosity, density, and calorific value were measured using ASTM D 445, ASTM D 92, and ASTM D 250.  The results show that the limonene gave many impacts on the change of properties fuel. Limonene is a non-polar compound with high intramolecular force intensity. It causes a spontaneous dipole and gave propagation effect on premium gasoline molecular compound. The effect influences dynamic molecular distribution by increasing the attractive force between opposite pole of premium gasoline and bio-additives blend. The decrease of intermolecular movement intensity will decrease the viscosity of the mixture. In contrary, the kinematic viscosity of the mixture will increase with increasing bio-additive concentration. In other pysical properties, the premium gasoline-bio-additive blends have low density at 1%, 5%, 10% and 25% addition concentration but it has high heating value of fuel blends.

Published: June 2021

The work presented in this paper is to investigate the wear rate and wear mechanism of medium carbon steel with carbon contents of about 0,5 wt.% under the friction load with various contact surface temperatures. The wear test was performed by using the linear reciprocating ball-on-flat wear test machine. To develop the elevated temperature on the surface of the wear test specimen, the heater assembled into the wear test machine. The surface temperature of the wear specimen was set in the range of 30 ºC up to 250 ºC. The test was taken under 5000 cycles of friction loading with a maximum of the normal load of 25N. The experiment results show that the change in the contact surface temperature in the range of 30 ºC up to 250 ºC causes the wear rate to increase slightly. This is because the elevated temperature at the surface was not high enough to cause the hardness of the material to decrease significantly. The worn surface looks very thin scratches and slightly deformed layers, and the wear mechanism had identified as oxide wear.

Characteristics of composite materials that are light, strong, heat resistant, and high hardness are needed in their application. This study aims to obtain a hard material and good heat conductivity, with the innovation of making aluminum matrix composites (AMC) from aluminum powder as a matrix, combined with silicon-carbon whisker (SiCw) and alumina particles (Al2O3p), and adding Magnesium through the powder process metallurgy. The method of making composites was carried out by means of powder metallurgy. The research variables composition I, II, and II with Al/(SiCw+Al2O3/Mg), were given temperature treatment: 500, 550, and 600oC. The test results show that there is an increase in the mechanical properties of the composites both from variations in composition and also from variations in treatment temperature because the bond resulting from the addition of Al2O3 reinforcement has hard and fine grain properties. The physical and mechanical properties of the test results are in the form of the highest density at composition I, 600oC (2,699 gr/cm3) while the hardness at composition III is 600oC (42,438 HV) and heat conductivity at composition III, 600oC (185,183 Watt/m.oC). Scanning with SEM showed that the pore size decreased from the treatment temperature of 500oC to 600oC due to phase changes and a stronger bond between the matrix and the reinforcement. So that the influence of composition and temperature will affect the thermal conductivity, hardness, and density of the composites.

Environmentally friendly lubricants are lubricants that are easily dissolved in the environment and are not harmful to the ecosystem. It uses to reduce the heat in the contact area so that the machinability of the workpiece and the ability of the chisel will increase. To minimize the use of bio-cutting fluids, lubrication is carried out by minimum drop lubrication in the lathe process. The purpose of this research is to comply with the surface roughness of the workpiece and the shape of the chip. The material used is aluminum 6061, the natural oil used are rubber seed oil, virgin coconut oil, sunflower seed oil, and castor oil. The turning parameters were the depth of cut 0.5 mm, spindle speed of 330 rpm, feed rate 0.231 mm/rev, tool angle 90o, drop lubrication 192 ml/hour, infeed length 100 mm. The results of the research showed that virgin coconut oil has the lowest surface roughness. This is because the viscosity value of virgin coconut oil is very small so that the flow rate is able to work perfectly to lubricate the contact area. It has a thin chip configuration, the tool also wears but did not experience cracks.

Cilj: Depreskripcija označava ukidanje, smanjivanje doze ili zamjenjivanje lijekova u pacijenata s progresivnom i neizlječivom bolesti radi postizanja najbolje moguće kvalitete života. Palijativni bolesnici uzimaju više različitih lijekova u zadnjim danima života, što može rezultirati većim rizikom nuspojava ili smanjivanjem koristi lijekova koji se uzimaju. Cilj ovog rada je analizirati propisivanje potencijalno nepotrebnih lijekova u uvjetima hospicijske skrbi koristeći OncPal smjernice za depreskripciju. Ispitanici i metode: Retrospektivno je analizirano korištenje potencijalno nepotrebnih lijekova u 790 onkoloških palijativnih bolesnika liječenih u ustanovi za palijativnu skrb „Marija K. Kozulić“ u Rijeci, od 2013. do 2017. koristeći OncPal smjernice za depreskripciju. Rezultati: Bolesnici su koristili u prosjeku šest različitih lijekova u svakodnevnoj terapiji. Od analiziranih sedam skupina lijekova iz šest klasa potencijalno nepotrebnih lijekova prema smjernicama OncPal, najčešće su korišteni gastroprotektivi – 61,9 % pacijenata, a do 30,6 % bolesnika koristi ih potencijalno nepotrebno. Antihipertenzive koristi 39,6 % bolesnika, a do 30,6 % potencijalno nepotrebno, kao što je i korištenje vitamina i minerala u 7,2 % bolesnika te statina u 6,3 % bolesnika. Niti jedan bolesnik nije koristio bisfosfonate. Antikoagulansi se koriste u 4,4 % slučajeva, a hipoglikemici u 12,8 %. Zaključci: Čak dvije trećine bolesnika liječenih u hospicijskoj skrbi koristilo je barem jedan potencijalno nepotreban lijek. Stoga je potrebno razvijati ideju depreskripcije te poticati razvoj i korištenje smjernica, poput OncPal smjernica, kako bi se racionalizirala farmakoterapija u bolesnika u palijativnoj skrbi s ciljem smanjivanja nuspojava i podizanja kvalitete života
Термодинамический цикл Брайтона с обратимой химической реакцией
Authors: Сабденов К.О.
Published: June 2021

The Brighton cycle is considered, where a chemically reacting gas is used as a working substance and its molar weight and heat capacity change because of a reversible chemical reaction. The lower T_low characterizes a cycle with a constant heat supply and upper T_top temperature limits of existence, between these limits the thermal efficiency can vary from 0 to 1. Such unusual properties are manifested due to two factors: the reversibility of the chemical reaction and the special role of chemical work in the transformation heat into mechanical work.

Light emitting III-N heterostructures were grown by metalorganic chemical vapor deposition on the SiC/Si (111) templates (substrates) formed by the method of matched substitution of atoms. Investigations of the optical and structural properties of heterostructures were carried out in order to reveal the formation of defects in the structures. It is shown that features of the growth of the (Al, Ga)N buffer layers in such structuresare associated with the presence of pores in the Si substrate under SiC/Si interface. Applying of the optimal design of the buffer layer allows significantly reduce the dislocation density and form active region with high structural quality.

The City of “Matera” Cultural Capital and Cinematographic Destination with the Power of Literature
Authors: Maria Manola , A. Tsatalbassoglou
Published: June 2021

Aliano is a small village in the province of Matera (Note 1). The city is characterized by the exceptional nature and the uniqueness of a “lunar landscape”, of a vast expanse of eerie beauty. The area was not always accessible for the same reasons, it became world famous for completely different reasons and specifically through the novel of a writer called Carlo Levi (Note 2). This particular author has left a strong mark on the history of Italian literature, although his work is not very rich. The place and the conditions of his new life as an exile in a poor isolated village of southern Italy, became the reason for the creation of his most important book entitled "Christ stopped at Eboli (Note 3).The book presents the rural south of Italy through its social condition, but not only as the result of an unbearable for the country archaic condition, but also as a place of existence of an important civilization. In this way the author’s narrative, as argued by Palmieri (2020), works as an objective account that is subjectively equated to a literary form.[… Christ did not arrive at this dark land where there is no sin and redemption, where evil is not moral, but an earthly pain that always exists in life. Christ stopped at Eboli.] (Levi, p. 12).

PETOOKTOBARSKA “UGOVORNA” PREVARA NARODA
Authors: Suvakovic Uros
Published: June 2021

U radu se analizira sadržaj izbornog dokumenta tadašnje Demokratske opozicije Srbije “Program za demokratsku Srbiju” (nazvan i “Ugovor s narodom”), pre svega ona obećanja – 10 tačaka – koja je DOS predstavio kao akte koje će usvojiti „prvog dana prvog zasedanja novoizabrane Skupštine“. Sa distance od dve decenije moguće je utvrditi u kojoj su funkciji bila obećanja DOS-a na izborima 2000, da li su tada data obećanja ispunjena i u kojoj meri, te izvesti zaključak o neuspešnosti vlasti DOS-a i teškim posledicama te politike po zemlju. U cilju objektivizacije ocene o neuspešnosti DOS-ove politike primenjeni su kriterijumi objektivizacije napretka i nazatka koje je svojevremeno utvrdio akademik Radomir Lukić.
O GUBITKU TERITORIJA I ASIMILACIJI PRAVOSLAVNIH SLOVENA
Authors: Milosevic Zoran
Published: June 2021

Prema podacima Konrada fon Hesnera u XVI veku bilo je 60 naroda slovenskog jezika. Preostalo je 14, dok su ostali asimilovani i izbrisani sa etničke mape. Takođe, teritorije koje su Sloveni izgubili iznose blizu 700.000 kvadratnih kilometara. Uz sve to Zapad i dalje nastoji da preostale pravoslavne Slovene uništi stvarajući nove narode sa ideologijom mržnje prema narodu iz kog su potekli.
Takođe, na udaru su se našle i pojedine institucije pravoslavnih Slovena, pre svega Crkva, gde se vodi politika poništavanja ili odricanja od autokefalnosti i njihovo potčinjavanje Fanaru, tačnije konstantinopoljskom patrijarhu kao novom istočnom papi.

Published: June 2021

Acute rheumatic fever (ARF) triggered by Group A streptococcus bacterium due to post-infectious and non-supportive pharyngeal infection. Depending on certain conditions, such as genetic predisposition to the disease, the prevalence of various cases of rheumatism and socioeconomic status in different regions, ARF can have different clinical manifestations. The disease typically manifested by one or more acute episodes, whereas 30-50% of all repeated ARF status can result in chronic rheumatic heart disease (RHD) with gradual and irreversible heart valve damage and also have been found to be correlated with a raised risk of myocardial infarction (MI), cardiovascular disease (CVD) and dyslipidemia. The RHD is the only long-term consequence of ARF and the most serious. The development to chronic RHD is determined by many factors, most notably the frequent episodes of rheumatic fever (RF). The RHD is known socially and economically as being the most frequent heart disease in vulnerable populations. H.pylori infection has been proposed to be involved RHD greater than that of the normal healthy people. H.pylori can be considered as one of the probable risk factor for RHD.It was concluded that patients with H. Pylori should be advised to follow up in cardiology clinics to avoid any complications.
