ONYMS AS REPRESENTATIVES OF THE GOSPEL CODE OF LITERARY TEXTS BY A. P. PLATONOV
Authors: Bugakova Nadezhda
Published: August 2024

The work is devoted to the analysis of the onyms included in the Gospel code of A. Platonov’s literary texts. The relevance of the research is due to the absence of works revealing the peculiarities of using onyms as representatives of the Gospel code of Platonov’s literary texts. Continuous sampling, linguistic observation and description, textual analysis, and analysis of the cultural and historical background methods were used in the research. In the writer’s worldview, social, religious, philosophical and mythological components are closely intertwined, and the writer’s attitude to religion and God is ambiguous. This resulted in the unique implementation of the gospel code in Platonov’s artistic texts, which are represented by biblionyms (the writer uses the names of Orthodox holidays, icons, excerpts from prayers as the titles of his works) and chrononyms (the names of Orthodox holidays). With the help of onyms representing the gospel code, the author sacralizes the names of political figures. Allusions to the Old and New Testaments arise in A. Platonov’s literary texts: the author refers to parables and legends that are traditional in a believer’s representation of the world, but religious subjects in the writer’s works are reinterpreted, due to the existing attitude towards religion in society.
HYPERSONET BY YURI LINNIK “BARTHOLOMEW” AS PART OF HIS BOOK “TRINITY”
Authors: Fedotov Oleg
Published: August 2024

The article considers an innovative modification of the classical stanza — the so-called hypersonet, which was used in his work by the outstanding master of Stefanism, the author of six hundred and fifty exceptional wreaths of sonnets, Petrozavodsk poet Yuri Vladimirovich Linnik. The term “hypersonet” was also used by other poets, but in their interpretation, it does not fit into the adopted system of traditional typology of either classical sonnets or their derivatives. Linnick applied this stanza predominantly in the beginnings of his many original almanacs and poetry collections, most often as a preamble to the wreaths of sonnets. The Linnik hypersonet structure combines three quatrains and three tercets: AbAb AbAb AbAb + CDe CDe CDe. In the main part of the article, the hypersonet “Bartholomew,” which opens the “Trinity” poetic collection, is subjected to a comprehensive analysis. The collection consists of 6 wreaths of sonnets and 19 poems. Three wreaths (“Cyril and Mary,” “Trinity” and “Sergius of Radonezh”) are dedicated to the great abbot of the Russian land who blessed Dmitry Donskoy for the victorious Battle of Kulikovo which became decisive for the liberation from the Tatar-Mongol yoke. The key to overcoming princely strife and national disunity was the most suitable cult of the Trinity as a “focus of higher harmony.” The most important conclusion that the author avidly asserts states: Trinitism, which harmoniously corresponds to the architectonics of the hypersonet, was also its generating factor.
Christian Axiology of the Characters of the Novel by V. S. Grossman᾽s “Life and Fate”
Authors: Kondratiev Alexander
Published: August 2024

V. S. Grossman’s dilogy “For a Just Cause” and “Life and Fate” may well be considered part of the Soviet literature corpus, but it can also be analyzed in the context of the “big time” of Russian culture, which is proposed in this work. The Battle of Stalingrad is reflected in the family history of Alexandra Vladimirovna Shaposhnikova. The novel “For a Just Cause” begins with a family celebration in her house before the attack of the enemy army and with the household’s plans for the alarming future. “Life and Fate” ends with a meeting of her loved ones before returning to a peaceful life, when it’s time to reflect on the losses and gains. Continuing Tolstoy’s tradition of emphasizing the spiritual evolvement of man in war, Grossman is guided by the national identity categories that date back to the opposition of Law and Grace. In the novel “For a Just Cause” the description of the military-historical trials of the Orthodox people comes to the fore, while “Life and Fate” is about the gracious influence of the Holy Spirit on the destinies of the world and man. In the “big time” of Russian culture, the actualization of the artistic installations of “socialist realism” in the first part does not matter, as does the reduction of the second book to military subjects or to the issue of freedom in the legalistic field, on the verge of lawlessness. The results of the heroes’ life quests are conditioned by the value orientations that dominate their minds: for the humble fulfillment of what fate has ordained and for a gracious personal evolvement

In this work, the effect of ultrasonic dispersion time on the dielectric properties and conductivity of nanocomposites was studied. Model systems based on polyethylene glycol and montmorillonite (PEG-MMT) were prepared. All samples had the same composition and filler content (5% by weight), and the ultrasonic treatment time ranged from 5 to 12 minutes. To determine the dependence of the properties of the systems on the dispersion time, the method of dielectric relaxation spectroscopy was used. It was found that an increase in the dispersion time leads to an increase in the dielectric constant of the systems. The effect of increasing the dispersion time on the dielectric constant in the case of the PEG-MMT system is similar to the effect caused by increasing the nanoclay content due to the decrease in the mobility of the macromolecular segments and the partial intercalation of the polymer into the interlayer space of the MMT. When analyzing the relaxation characteristics of the investigated systems, it was found that as the dispersion time increases, the relaxation regions shift toward higher frequencies, while the relaxation time decreases. This phenomenon is explained by the inhibition of the segmental mobility of the macromolecules due to the increase in the number of steric hindrances caused by the delamination of MMT. In addition, there may have been an increase in the number of charge carriers that are released during the intercalation of the polymer into the interlayer space of MMT, leading to their contribution to the dielectric properties in the form of conductivity relaxation. The experimental values of electrical conductivity at alternating current for the PEG-MMT system were modeled using the Jonscher equation. From the obtained parameters, a change in the degree of interaction between the charge carriers and the matrix was revealed, which is a consequence of the initial delamination of montmorillonite plates, and then their subsequent aggregation into denser structures, the area of interaction with the polymer matrix is much smaller.

The effect of the chemical structure of vinyl chloride-based polymers, such as poly(vinyl chloride) (PVC), chlorinated PVC (cPVC), vinyl chloride/vinylidene chloride copolymer VCVD-40TM, vinyl chloride/vinyl acetate copolymer А-15TM on its compatibility with poly(ether-urethane)urea elastomer (PUU) was studied by DSC and FTIR spectroscopy. The segmented PUU was synthesized by prepolymer approach in N,N-dimethylformamide (DMF) solution using poly(propylene glycol) of number-averaged molecular weight (Mn) of 1000 Da, 2,4-tolylenediisocyanate and tolylene 2,4-diamine as a chain extender at a molar ratio of 1:2:1. PUU/vinyl chloride-based polymer blends was prepared by solution casting technique vie DMF solution. It was found a compatibility of PUU based blends containing 30 % PVC (PUU/30PVC blend) or cPVC (PUU/30cPVC) were initiated by strong hydrogen bonding. As a result, the blends are characterized by single wide relaxation transition. A glass transition temperature (Тс) of PUU/30PVC composite is similar to the theoretical one (ТFс), which is calculated using the Flory-Fox equation, whereas Тс value of PUU/30cPVC composite is higher than ТFс. Introducing polar vinyl acetate or vinylidene chloride fragments into vinyl chloride-based polymer macrochains suppresses the compatibility of components of the polymer blends and initiates the formation of a biphase microheterogeneous structure. The formation of intermolecular hydrogen bonding network at the interface in polymer-polymer blends is confirmed by FTIR spectroscopy. Comparative analysis of experimental and theoretically calculated (additive) tensile characteristics of polymer blends demonstrates their substantial dependence on interface interactions between the constituents. The highest strengthening effect was observed for cPVC or PVC-containing nanocomposites.

Polyurethane materials of different composition and structure were prepared using diisocyanates of different nature, native and functionalized vegetable oils. Hydroxylated derivatives of hemp oil, namely lineoyl diethanolamide (LDEA), whose structure was confirmed by IR spectroscopic studies, were obtained by amidation of hemp oil with diethanolamine. LDEA is used as an isocyanate extender of functionalized castor oil with the formation of film-forming materials (content of components of naturally renewable origin up to 70%). A decrease in the strength characteristics of synthesized polyurethanes from 31 to 18.8 MPa and an increase in their elasticity is due to the presence of the fatty acid fragment in LDEA. The content of LDEA (internal plasticizer) can be a factor in regulating the level of strength-elastic properties, and its presence in the composition of polyurethane contributes to increased resistance in an acidic environment. Analogues of the specified material were prepared using diethanolamine as an extender. Aggregatively stable (more than 12 months) film-forming aqueous polyurethane dispersions containing LDEA (10 and 20 wt.% in the composition of oligomeric diols) were prepared. The size of their dispersed phase is 460–328 nm, which decreases with increasing LDEA content. The breaking strength indicators of film materials obtained based on IPU increase with the increase of LDEA content from 4.76 MPa to 5.86 MPa, respectively, and the relative elongation decreases from 469 to 430% with the content of LDEA 6.8 and 13.5 wt.%, respectively. Since the weight loss in alkaline and acidic environments decreases with increasing content of lineoyl diethanolamide in the dispersion, its presence in the composition of anionic polyurethanes is a factor in increasing their stability in aggressive environments.
A familial subtype of gambling disorder
Authors: Grant Jon E. , Aslan Ibrahim , Chamberlain Samuel R.
Published: August 2024

Background

Although family history of psychiatric disorders has often been considered potentially useful in understanding clinical presentations in patients, it is less clear what a positive gambling family history means for people with gambling disorder. We sought to understand the clinical impact of having a first-degree relative with gambling disorder in a sample of adults with gambling disorder.

Methods

Data from 455 participants (aged 18–65 years) who had participated in previous pharmacological and psychotherapeutic clinical trials for gambling disorder were pooled in a secondary analysis. Demographic and clinical variables were compared between those who did versus did not have one or more first-degree relative(s) with gambling disorder. Additionally, we examined whether a family history of gambling disorder was associated with treatment outcome.

Results

223 (49.0%) participants had at least one first-degree family member(s) with gambling disorder. In terms of clinical variables, family history of gambling disorder was significantly associated with being female, having an earlier age of gambling onset, longer duration of untreated gambling illness, a greater likelihood of developing legal problems secondary to gambling, and higher rates of alcohol use disorder in family members. Family history of gambling disorder was also associated with a greater gambling symptom improvement from pharmacotherapy.

Conclusions

These results indicate that gamblers with a first-degree family member with a gambling disorder may have a unique clinical presentation and better response to treatment interventions.

Published: August 2024

This article aims to explain the construction of ecotheology from the perspective of contemporary interpreters based on comparison of contemporary interpretive texts. The creation of humans as caliphs on earth which has the meaning of being a substitute has experienced a shift in meaning in several contemporary interpretations. This theoretical study of environmental issues was studied using descriptive qualitative methods through interpretation results with plural dimensions. The data processing and analysis process is carried out using content analysis methods in thematic interpretation aspects related to environmental issues. A number of terms related to ecology in the Al-Qur'an show the relationship between human rights and environmental rights. Humans are ecologically part of the living environment, so the sustainability of human entities actually depends on environmental balance. The universe has a human right to be treated as well as possible as a life partner for humans to carry out their shared roles in serving God.

Published: August 2024

Flying fish Cypselurus poecilopterus is a small pelagic fish resource that plays an important ecological and economic role. However, information regarding the structure of its stock in East Indonesian waters is still limited. This study aims to identify stock structure based on morphometric, meristic approaches, and associated with environmental factors. Fish samples were taken during one fishing season (June-September) in 2015 and 2021 in the waters of West Papua and East Seram where the Lydakker line passes, using the method of observation and purposive sampling, then the data were analyzed descriptively and t-test. The results of observations on 23 morphometric characters and 5 meristic features showed a significant difference, so it is estimated that flying fish stocks are composed of 2 sub-populations. Differences in morphometric and meristic parameters are affected by different environmental conditions in the two waters. This information is expected to be useful for the management and sustainable use of flying fish resources.

Authors: Hauen Mali , Sessay Muhamed , Marcetic Neven , Knudsen Hein Økseter , Støholen Morten , Nyaas Gunhild
Published: August 2024

This video article illuminates what stories can be told about kulturskolen — Municipal Music and Performing Arts Schools in Norway — when pupils are the storytellers. The method is based in collaborative, long-term, performative work with a group of students in a particular kulturskole. These students Were asked to consider the question: “What does the phenomenon of the kulturskole do to us?”
The primary researcher (Hauen) met with the students once per week for five months and produced videos, recordings, and notes in response to this question. Afterwards, she edited and cut the data in order to analyze the process, drawing on the work of Karen Barad and post-qualitative thinking. This resulted in three important findings, according to the students: togetherness, self- expression, and “perfor-managing.” In the video article, the students tell stories about how they develop these three elements, in the kulturskole and in the world. They ask how the kulturskole phenomenon is relevant to their everyday lives and how it helps them “to find peace and the right way,” as one of them raps in the article. In order to provide additional insight into the methodology of entanglement between researcher and participants (the students and their teacher), a concluding discussion follows the main video.
Neuromodulation guide for the non-neuromodulator clinician: What it is and how it can benefit patients?
Authors: Hoffmann Chelsey , Wang Jinlan , Ali Rushna P. , D'Souza Ryan S.
Published: August 2024

Neuromodulation is being utilized across a variety of medical subspecialties to treat both painful and non-painful medical conditions. However, publications on neuromodulation topics infrequently occur in journals targeting generalists and medical specialties outside of pain medicine and neurosurgery. This study reviewed implantable neuromodulation devices, their respective Food and Drug Administration-approved indications for use, as well as off-label usage, and the associated potential risks and benefits for each device. PubMed and Medline databases were queried for systematic reviews with or without meta-analyses and randomized controlled trials of implantable neuromodulation devices. The literature review resulted in 106 studies eligible for inclusion, and 67 were included in the final review. In conclusion, as the clinical volume of neuromodulation continues to grow, supporting and educating medical professionals who care for patients that receive implanted neuromodulation devices is paramount. It is likely the use of neuromodulation will continue to expand across all medical subspecialties, and as such, every clinician should have a baseline understanding of this treatment.
An uncertain programming model for fixed charge transportation problem with item sampling rates
Authors: Sang Tianyu , Zhu Kai , Shen Jiayu , Yang Lin
Published: August 2024

This paper analyzes the transportation issue involving multiple objectives and items with fixed costs amid uncertainty, which aims to increase net profit while minimizing carbon emissions, to determine an optimal product shipping strategy. This paper introduces the use of uncertain theory to address the transportation dilemma, considering various challenges such as potential uncertainties during the actual transport process. It involves defining variables such as supply, demand and the rate of product sampling qualification as uncertain factors, constructing mathematical models, and deriving the corresponding model as well as the respective equivalent form by means of uncertainty theory. A linear weighted method is adopted to reflect the significance of each objective as identified by policymakers and suggest a sparrow optimization algorithm combined with butterfly search for numerical experiments to discover the optimal solution. This demonstrates the practicality and effectiveness of the proposed models.
Rolling bearing fault diagnosis method based on multi-scale pooling residual convolutional neural network under noisy environment
Authors: Lei Chunli , Miao Chengxiang , Yu Yongqin , Wang Lu , Wang Bin
Published: August 2024

To address the issues of unstable performance and poor generalization ability of bearing fault diagnosis model caused by strong noise and variable operating conditions in actual production，this paper proposes a rolling bearing fault diagnosis method based on MSPRCNN model. By converting vibration signals to frequency domain with FTand utilizing wide convolution kernels for feature extraction, the approach aims to enhance fault detection. A MSPFE module captures information at different scales to simplify complexity, while an UPA module establishes correlations between frequency domain positions. To reduce the impact of noise and address the vanishing gradient problem, the MSPRCNN model employs GC instead of standard convolution, and utilizes the IReLU activation function to improve model feature representation. Experimental results on two datasets show that the fault recognition accuracy is 98.71% under variable loads and 98.2% under variable speeds. The MSPRCNN model outperforms other methods in fault recognition and generalization in noisy environments.
Degradation generation and prediction based on machine learning methods: A comparative study
Authors: Li Xintong , Song Kai , Shi Jian
Published: August 2024

In engineering practice, degradation analysis often suffers from the small-sample problem. To this end, several generative models are developed to expand the degradation data, based on which both the original data and the synthetic data are used to train neural networks for degradation prediction. However, these methods are rarely compared with each other, and the performances of competitive candidates are not explored. Given this, this paper reviews some machine learning-based methods and performs a comparison among them. Particularly, a segmented sampling method is proposed and the diffusion model is introduced for degradation generation. Results of both numerical simulations and case studies show that none of these methods can perform best in all cases, yet making use of synthetic data improves the predictive performance. Overall, the time-series generative adversarial network and the segmented sampling method are recommended for degradation generation, and the gated recurrent unit network is recommended for prediction.

Published: August 2024

Aiming at the problems of small sample size, few test failure data and low reliability evaluation efficiency in accelerated life test of high-reliability and long-life products, an improved virtual augmentation Bootstrap-Bayes reliability evaluation method based on small sample accelerated life test data was proposed. Firstly, the test data under various stress conditions are augmented by virtual fusion. Secondly, the empirical distribution function and bootstrap sampling method are improved, and the kernel density estimation method is used to fit the density distribution of test data as prior information. Then, the parameter estimates of the test data are obtained by Gibbs sampling combined with Bayes formula. Finally, the reliability index under normal stress level is obtained by accelerating model extrapolation. The feasibility of the proposed method is verified by the accelerated life test data of a type of Ship communication equipment.

Resumen En el período comprendido entre julio y octubre del  año 1997 se evaluaron 360 intestinos de cerdos sacrificados en el Matadero Municipal de Medellín, Colombia, con el objetivo de establecer  la prevalencia de la Enteropatía Proliferativa Porcina (EPP) en el departamento de Antioquia, caracterizar las lesiones anatomopatológicas asociadas y determinar la presencia de su agente etiológico Lawsonia intracellularis. El cálculo de la muestra se efectuó de una población tabular infinita con un límite de confianza del 95% y una seguridad de ±5%. Las muestras obtenidas se sometieron a inspección macroscópica y evaluación histopatológica utilizando  las coloraciones de Hematoxilina-Eosina y Warthin-Starry. El análisis de los resultados se efectuó  mediante estadística descriptiva y la prueba de independencia y contingencia (chi-cuadrado). La prevalencia de EPP fue del 87.22%, determinada por la presencia de las lesiones características de la enfermedad asociadas a su agente etiológico L. intracellularis. Las formas lesionales más frecuentes fueron: Adenomatosis Intestinal en un 74.72% e Ileítis Regional en un 20.55%.  Este artículo   discute los hallazgos epidemiológicos y anatomopatológicos de EPP en el departamento de Antioquia y se constituye en el primer reporte del hallazgo de una bacteria como L. intracellularis diagnosticada por un método directo en Colombia. Palabras clave: adenomatosis, ileítis, intestino, Lawsonia intracellularis, suino. Summary With the aim of find the prevalence of porcine proliferative enteropathy in the state-like of Antioquia, characterize its associated anatomo-pathologic lesions and to determine the etiological agent Lawsonia intracellularis. 360 intestinal tracts were evaluated at the abattoir of the municipality of Medellín, Colombia. This study took place between July to October of the year 1997. The sample calculation was obtained from a tabular infinite population with a confidence level of 95% with an error of ± 5%. All samples were gross inspected and then histologically processed by two types of stains, Hematoxiline-Eosine and Warthin-Starry.  The analyses of these results were done by descriptive statistics and chi-square contingency tables. The prevalence of PPE was 87.22%, by the recognition the associated lesions caused by Lawsonia intracellularislike organisms. The most frequent lesion forms were intestinal adenomatosis 74.72%, and regional ileitis (20.55%). This paper discusses the epidemiological and pathologic findings of PPE of this region. For this reason, it constitutes the first report by a direct method in Colombia that diagnoses the presence of L intracellularis like bacterium. Key words: adenomatosis, ileitis, intestine, Lawsonia intracellularis, porcine.

Authors: Hernández Carlos , Botero Marcela
Published: August 2024

Resumen La meningitis arteritis que responde a esteroides es una inflamación de las meninges y de las arterias del sistema nervioso central, de aparente mediación inmunitaria y de presentación clínica conocida y descrita pero de etiología incierta y patogenia en proceso de investigación. Se describen los primeros dos casos reportados en Medellín de características clínicas típicas de enfermedad meníngea con sintomatología clásica (fiebre, dolor paravertebral, renuencia a moverse, dolor a los movimientos del cuello) en dos perros de raza Beagle. Se describen los métodos clínicos utilizados que condujeron al diagnóstico definitivo mediante su presentación clínica, análisis de líquido cefalorraquídeo y respuesta al tratamiento que llevó a una resolución satisfactoria de ambos casos. También se describen las complicaciones por el uso prolongado de corticoides presentadas en ambos casos clínicos. Palabras clave: beagle, corticoides, meningomielitis. Summary Steroid responsive meningitis arteritis is an inflammation of the meninges and the arteries of the central nervous system with an apparent immune - mediated origin having a well-characterized clinical course but uncertain etiology and its pathogenesis is still a subject of intense research. In this report we describe the first two cases reported in Medellín that represent the characteristic clinical course of the meningeal disease (fever, paravertebral pain, incapacity to move, cervical pain) in two Beagle dogs. We describe the procedures to make a definitive diagnostic based in its clinical course, cerebrospinal fluid analysis an response to therapeutics that allow a complete resolution in both cases. Collateral effects of this two corticoid - treated dogs are also presented. Key words: beagle, corticosteroid, meningomyelitis.
Comportamiento de los peces en la búsqueda y la captura del alimento
Authors: Botero Aguirre Mónica
Published: August 2024

Resumen La conducta alimentaria de los peces presenta una alta interdependencia con el medio acuático, su respuesta está asociada a la condición jerárquica y la producción de feromonas, a la presencia de depredadores, a los movimientos de la corriente originada por los diferentes tipos de habitantes acuáticos, lo que incide en la manera como se hace la búsqueda, la  localización y la captura; a las conductas de aprendizaje (consumo-rechazo) y a los hábitos de consumo, entre otros, que tienen efecto sobre la dieta consumida y su eficiencia alimenticia, lo que se necesita como punto de partida para garantizar la supervivencia de la especie.  Conocer estos aspectos permite diseñar la dieta ideal para las diferentes especies de acuerdo a su fase de vida, y estos hallazgos podrían aplicarse al desarrollo de alimentos para las especies nativas de Colombia, de los cuales no se conoce su ecobiología ni su etología alimentaria. Palabras clave: alimento, comportamiento, depredación, estímulo, presa. Summary The feeding behavior in fishes has interdependence with the aquatic habitat, it is also associated with hierarchy and pheromones production, predation risk and flow movements originated by different kinds of aquatic animals. All of those aspects can affect the findings of the capture and learning curve (acceptance - rejecting of food), its behavior among others and may also determinate the quality of food and finally the feeding efficient. To know this subjects it is important to design the optimum diet for each kind of fish to ensure its survival and it could specially help to understand which are the best foods for native colombian fishes, related to their unknown ecobiology and feeding ethology. Key words: behavior, food predation, prey, search, stimulus.

The possibility that the virus exists in this country is discussed to the time and it is suggested to research about this fact. Key words: bovine herpesvirus, encephalitis, polioencephalomalacia.
Papel de los adyuvantes en la modulación de la respuesta inmune
Authors: Franco Diego A.
Published: August 2024

Resumen La inmunoprofilaxis es una herramienta valiosa en la prevención de las enfermedades infecciosas; ésta depende de la capacidad del sistema inmune para reconocer y desencadenar una respuesta efectora y de memoria ante los estímulos antigénicos usados como vacunas. Actualmente, existe la necesidad de desarrollar y mejorar las vacunas no replicativas ya existentes de manera que modulen e incrementen la efectividad de la respuesta inmune. Los adyuvantes constituyen una opción en el mejoramiento de este tipo de vacunas ya que incorporados en la formulación de éstas aumentan, aceleran o prolongan la calidad de la respuesta inmune a antígenos específicos. Los adyuvantes pueden ser clasificados de acuerdo a su mecanismo de acción en dos tipos: inmunoestimuladores y sistemas de liberación. Los adyuvantes inmunoestimuladores son derivados de patógenos (lipopolisacáridos, CpG) y su función es activar las células del sistema inmune innato. En contraste, los sistemas de liberación son partículas (emulsiones, micropartículas, ISCOMs) encargadas de entregar el antígeno asociado a una célula presentadora de antígeno. El descubrimiento y desarrollo de nuevos adyuvantes abre la posibilidad de implementar en un futuro vacunas terapéuticas y profilácticas contra el cáncer y enfermedades infecciosas agudas y crónicas que sean más eficaces y seguras para ser utilizadas en humanos y especies animales de importancia económica. Palabras clave: adyuvantes inmunoestimuladores, sistemas de liberación, vacunas. Summary The immunoprophylaxis is an important tool in the prevention of the infectious diseases; it depends of the capacity of the immune system to recognize and develop an effector response and immune memory against different stimulus. Currently, it is necessary to develop and improve the existent nonreplicating vaccines with the purpose to modulate and increase the immune response against a wide range of microorganisms or their antigens. The adjuvants constitutes an option to improve this type of vaccines because when they are incorporated in a vaccine formulation can enhance, accelerate or prolong the quality of the immune response to specific antigens. Adjuvants can be classified according to their action mechanisms into two types: immunoestimulatory and delivery systems. The immunoestimulatory adjuvants are derived from pathogens (lipopolysaccharides, CpG) and their function is to activate the innate immune cells. In contrast, the delivery systems are particles (emulsions, microparticles, ISCOMs) that transport and deliver an associated antigen to antigen-presenting cell. The discovery and development of new adjuvants opens the possibility to use new prophylactic and therapeutic vaccines against cancer, acute and chronic infectious diseases. These new vaccines will be more effective and safe to be used in human and animal species of economic importance. Key words: adjuvant immunoestimulatory, delivery systems, vaccines.
