El objetivo de este estudio fue determinar la distribución sanguínea de linfocitos T CD4, CD8, LT γδ (WC1) en carneros infectados experimentalmente con Brucella ovis. Se utilizaron 18 carneros de 1 a 4 años y libres de B. ovis distribuidos en tres grupos: Control (n=6); Inoculado en las mucosas ocular y prepucial (n=6); Inoculados vía endovenosa (n=6). Se realizó el seguimiento serológico desde el día de la inoculación hasta el 189 dPI (día pos-inoculación). Se inmunotipificaron las poblaciones de linfocitos CD4 y CD8 a los 120, 150 y 189 y de WC1 (linfocitos Tγδ) a los 120 dPI por citometría de flujo. Los carneros, a partir del tercer dPI comenzaron a seroconvertir; a los 21 y 28 dPI todos los animales de los grupos inoculados por vía endovenosa y mucosa, respectivamente, resultaron positivos; asimismo, el 50% de los animales de los grupos desafiados se presentaron como positivos o sospechosos a la prueba de ELISA a los 189 dPI. Se encontraron diferencias en las Medias de Intensidad de Fluorescencia (MIF) de los linfocitos CD8 entre el grupo control (1027.4) y el grupo inoculado por vía endovenosa (499.6) a los 120 dPI (p<0.05) y en las MIF de los linfocitos CD4 entre grupos a los 189 dPI (p<0.05). Las poblaciones linfocitarias T γδ (WC1) presentaron diferencias en MIF entre el grupo control y los grupos inoculados a los 120 dPI (p<0.05). Los resultados indican que B. ovis puede modular la respuesta inmune del hospedero, que los linfocitos CD4 y CD8 son importantes para la defensa del hospedero ante esta infección, y que las poblaciones de CD4 como de CD8 pueden fluctuar durante el periodo de infección por B. ovis. Así mismo, la participación de los linfocitos T γδ podría ser un factor importante en el control de la infección causada por B. ovis.

El objetivo del estudio fue determinar la eficiencia de un simulador bovino para prácticas de palpación transrectal. Se utilizó un simulador bovino comercial y cuatro hembras bovinas no gestantes. Se trabajo con 20 y 22 estudiantes sin experiencia en la técnica de palpación transrectal que participaron como grupo experimental (I) y control (II), respectivamente. Los estudiantes del grupo I fueron entrenados con el simulador para la ubicación de cérvix, útero y ovarios, mientras que los del grupo II recibieron una práctica tradicional, consistente en el trabajo con tractos reproductivos in situ. Luego, ambos grupos fueron evaluados por dos palpadores expertos en cuatro bovinos respecto a la correcta ubicación de las estructuras anatómicas. La prueba de Chi cuadrado determinó diferencias en el grado de precisión del reconocimiento de las estructuras anatómicas entre grupos (p<0.05), habiendo un mejor nivel de reconocimiento de las estructuras en el grupo experimental, indicando la utilidad del simulador para la identificación de la cérvix, útero y ovarios en las prácticas de palpación transrectal.

Published: October 2019

El objetivo del trabajo fue determinar la degradabilidad de asociación de forrajes y de residuos de cosecha comúnmente utilizados en la Región de Huancavelica en la alimentación de bovinos. Se evaluaron las asociaciones trébol blanco-ryegrass italiano y el trébol rojo-dactylis, y los residuos de cosecha: maíz chala, paja de avena, arveja, habas y quinua. Para la determinación de la degradabilidad de la materia seca (MS), proteína cruda (PC) y fibra detergente neutra (FDN) se utilizaron tres bovinos Brown Swiss, fistulados en el rumen. Los forrajes y los residuos de cosecha fueron colocados en sacos de nylon e incubados por 4, 8, 12, 24, 48, 72 y 96 horas. El tiempo cero (t0) fue utilizado para el cálculo de la fracción soluble. Las degradabilidades de la MS, PC y FDN fueron influenciadas por los forrajes y residuos de cosecha (p<0.05). La mayor degradabilidad potencial de la MS y PC, y degradabilidad efectiva de la MS, PC y FDN le confieren al trébol blanco-ryegrass italiano un buen potencial nutritivo para los rumiantes. La tasa constante (C) de degradación, degradabilidad potencial y degradabilidad efectiva de la PC permite considerar a los residuos de arveja, habas y quinua como recursos alimenticios de alta calidad nutricional. Por el contrario, la degradabilidad efectiva de la PC a la tasa de pasaje de 5%/h indica que el maíz chala y la paja de avena son alimentos de mediana calidad.
Determinación del porcentaje de viabilidad espermática mediante citometría de flujo durante el proceso de criopreservación en espermatozoides obtenidos de epidídimo de alpaca
Authors: Juárez Javier , Santiani Alexei
Published: October 2019

El objetivo del estudio fue determinar el porcentaje de viabilidad en espermatozoides epididimarios de alpaca, antes y después del proceso de criopreservación, mediante citometría de flujo. Se recolectaron 46 testículos de alpaca de un camal de Pasco, Perú y se utilizaron 41 de ellos con motilidad espermática ≥30% y concentración espermática ≥50x106 espermatozoides/ml. Los espermatozoides fueron recuperados de la cola del epidídimo con 1 ml de dilutor a base de leche descremada. separándose en dos alícuotas para evaluar la viabilidad antes y después del proceso de criopreservación. El dilutor fue retirado mediante lavados por centrifugación con PBS, los pellets fueron resuspendidos en 100 µl de PBS, agregándose 0.5 µl de SYBR-14 (100 nM) y 0.5 µl de ioduro de propidio – PI (12 µM) incubándose por 10 min a 38 °C. La evaluación de viabilidad espermática se realizó mediante citometría de flujo con analizador de imágenes, utilizando un láser de excitación de 488 nm y la fluorescencia emitida por el SYBR-14 y el PI fueron detectados por los canales Ch02 (505-560 nm) y Ch05 (642-740 nm), respectivamente. Los espermatozoides viables con membrana intacta emitieron fluorescencia verde (SYBR-14) y los espermatozoides no viables con membrana dañada emitieron fluorescencia roja (PI). La viabilidad antes del proceso de criopreservación (48.97 ± 11.47%) fue mayor (p<0.05) que después del proceso de criopreservación (32.30 ± 9.57%). La correlación entre viabilidad y motilidad espermática fue r=0.6737. Se concluye que el proceso de criopreservación disminuye significativamente la viabilidad en espermatozoides epididimarios de alpaca, estando este parámetro relacionado con la motilidad.

El margay (Leopardus wiedii) está considerado desde 1990 en el Apéndice I de CITES, y en la lista roja de la UICN. En el Perú está catalogado como “especie con datos insuficientes” dentro de la categorización de Especies Amenazadas de Fauna Silvestre del Ministerio de Agricultura y Riego (MINAGRI). El presente estudio tuvo por finalidad describir la morfología y topografía de los órganos abdominales del margay en cautiverio. El trabajo comprendió los seis especímenes, cinco hembras y un macho, criados en el Parque Zoológico de Huachipa, Lima, Perú. Los animales fueron anestesiados para realizar la técnica ecográfica. Se empleó un equipo Pie Medical modelo Falco, con un transductor multifrecuencial de 5-7.5 MHz. Se evaluó la topografía, forma, ecotextura, márgenes y arquitectura del hígado, vesícula biliar, riñones, estómago, bazo, vejiga urinaria y testículos. Se concluyó que las características ecográficas encontradas en el bazo, vejiga, hígado, estómago, vesícula biliar y testículos fueron similares en cuanto a ecogenicidad, márgenes y topografía a la de algunos carnívoros domésticos como el gato y el perro; la forma de los riñones fue alargada recordando más a la forma de los perros domésticos, en tanto que el bazo y el estómago presentaron formas ligeramente más alargadas que las descritas en el gato doméstico.

El objetivo de esta investigación fue evaluar la actividad antibacteriana de extractos de metanol y metanol-cloroformo de tegumento, gónada y víscera de Pattalus mollis. Se recolectaron 50 especímenes en la bahía de Pucusana, Perú, se diseccionaron longitudinalmente por la zona ventral del tegumento y se retiraron los órganos internos (víscera, gónada). Las muestras fueron secadas hasta un 10% de humedad, molidas y almacenadas en congelación. Los extractos fueron obtenidos mediante maceración empleando metanol y cloroformo. La evaluación in vitro se realizó mediante el método de microdilución en caldo, los extractos se diluyeron en siete concentraciones (3.9-250 mg/ml) y evaluados frente a Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 14775 y Vibrio alginolyticus ATCC 17749. Los extractos metanólicos presentaron inhibición bacteriana frente a las tres bacterias demostrando poseer un efecto bactericida y bacteriostático contra bacterias grampositivas y gramnegativas. Los extractos de víscera, gónada y tegumento presentaron una concentración mínima inhibitoria (CMI) de 62.5 mg/ml o más frente a P. aeruginosa, V. alginolyticus y S. aureus. Los resultados sugieren que el pepino de mar P. mollis, proveniente de las costas peruana, es un candidato novedoso para la obtención de compuestos antibacterianos.

Published: October 2019

El objetivo del estudio fue determinar los índices gonadosomático (IGS) y hepatosomático (IHS) en relación con la maduración gonadal y los estados de muda del camarón Cryphiops caementarius del río Pativilca (Perú). Se emplearon 143 camarones machos (4.07-11.70 cm de longitud total) y 97 hembras (1.75-8.02 cm de longitud total). Los camarones se pesaron, midieron y se determinó el estado de muda. Los hepatopáncreas y gónadas se extrajeron por disección, se pesaron y se determinaron los estados del ovario. Durante la maduración del ovario, el IGS incrementó de 0.97 a 5.01% y el IHS disminuyó de 5.37 a 4.44%. En hembras maduras y no ovígeras en postmuda A, el mayor IGS fue de 8.28% y el menor IHS de 1.72%. En hembras con ovarios inmaduros y no ovígeras, el IGS incrementó de 1.40 a 3.38% y en hembras inmaduras y ovígeras de 0.38 a 1.79%, en tanto que lo contrario sucedió en hembras maduras no ovígeras. En los machos el IGS varió de 1.74 a 0.78% y el IHS de 5.08 a 5.92% durante el ciclo de muda. En hembras el IGS incrementó conforme maduró el ovario y fue máximo en postmuda A y mínimo en postmuda B2; en cambio, el IHS varió de manera inversa con el IGS. En camarones machos los bajos IGS y los altos IHS sugieren que estos no invierten energía para reproducción.

Background: The sick building syndrome (SBS) is known as an unhealthy condition of occupants of a building, caused by environmental factors such as small space, poor ventilation, and different pollutants in the building. Symptoms of SBS include anxiety, respiratory, dermal, and sensory problems which start by entering a building or slightly after that, and disappear after leaving the building. The aim of this study was to determine the frequency of SBS in the employees of Shahid Beheshti hospital of Kashan. Methods: In a descriptive, cross-sectional study conducted, a sample of 279 randomly-selected employees of  Shahid Beheshti hospital in Kashan working during 2016-2017, were involved. The study was performed on four groups of doctors, nurses, servants and employees. To collect the data; a questionnaire was used. It consisted of two parts: demographic data and questions of SBS questionnaire of World Health Organization. The collected data were analyzed using SPSS; and statistical tests such as Chi square and Fisher's exact test were performed and logistic regression were used for multivariate analysis. Results: The prevalence rate of SBS in general, in women and in men was estimated 50.81%, 55.3% and 44.7%, respectively. Symptoms of indisposition(47.3%), skin dryness (41.5%) and headaches (38.9%) had the highest frequency. Studying SBS symptoms in different job groups showed that skin dryness and dry and sore throat in physicians were significantly less than those in the other groups (p<0.05). In logistic regression analysis, the only factor influencing SBS was the staff height (p=0.02). Conclusion: Considering the high prevalence of the symptoms of building syndrome in all of the four groups, paying more attention to improving the working environment, such as the efficiency of the air conditioner system and increasing the entry of fresh air into the departments, increasing the quality of work life would be of utmost importance which would result in motivating and increasing the productivity in the work environment.

Published: October 2019

Background: Behavioral-based safety interventions such as the safety training system and reward and punishment procedures were used in most industries in order to reduce unsafe behaviors. Methods: In this applied study, unsafe behavior was evaluated by collecting data through observation, interviews, checklists and the Safety Behavior Sampling technique. After conducting safety training, as well as reward and punishment procedures for two consecutive months, unsafe behaviors were evaluated again. To determine the rate and diversity of the behaviors through a pilot study, a sample size of 1162 was determined to be observed. Moreover, to analyze the data and to specify the relationship between the variables, the ratio test, contingency tables, chi-square test and SPSS 22 statistical software package were used. Results: The results of the study showed that 22.8% of employees’ behaviors were unsafe before applying interventions, which got decreased to 17% after the intervention. There was also a significant relationship between the unsafe behaviors of the employees and their work experience (P-value was 0. 004), age (P-value was 0.023), work shift (P-value was 0.027), day of the week (P-value was 0. 007) and month of year (P-value was 0. 043). Conclusions: The paper indicated that continuous implementation of safety training courses and continuous implementation of the reward and punishment system are necessary in order to reduce unsafe behaviors.

Published: October 2019

Purpose: The development of municipal service professional staff units is one of the most significant factors for Russian territory's sustainable development. Methodology: The information base of the research includes the results of sociological studies conducted by the All-Russia Council of Local Self-Government (ARCLSG) through the sending of questionnaires via the Internet: "Human Resources of Municipalities" (June-July 2013, N = 915); "Human Resources of Local Self-Government" (March-April 2016, N = 582). Result: The results of the expert survey showed that the leaders of local authorities are not fully satisfied with the level of municipal employee professional training. Evaluating the effectiveness of training programs implemented in recent years, most experts chose the following answer: "not all of the required issues have been covered, only a few things can be useful in practical activities". In modern conditions, it is necessary to specify the content of education, taking into account the specifics of the territory, its social and economic problems, the overcoming of a narrow theoretical orientation of the courses. Applications: This research can be used for the universities, teachers and education students. Novelty/Originality: In this research, the model of formation of municipal service human resource potential as a strategic factor for Russian territory sustainable development is presented in a comprehensive and complete manner.
Habilidades Socioemocionales de los Docentes, herramientas de paz en la escuela
Authors: Gutiérrez-Torres Adriana Marien , Buitrago-Velandia Sandra Jackeline
Published: October 2019

La escuela es el principal escenario formativo y de socialización del individuo. Allí se consolidan los imaginarios, realidades, subjetividades y conductas del estudiante. Por consiguiente, el papel de los docentes es fundamental, debido a que operan como guías y modelos de las reacciones, relaciones y vínculos interindividuales que se generan en el ambiente escolar. Gracias a ellos la escuela se configura como un escenario que posibilita la gestión del aula como un espacio en el que se puede aprender a experimentar la paz. El artículo se plantea como una revisión teórica respecto a cómo las habilidades socioemocionales de los docentes inciden en la gestión de los ambientes de paz en la escuela, teniendo en cuenta factores como el clima de aula, el conflicto escolar, la cultura de paz y las relaciones interpersonales, tanto entre docentes, como entre docentes y alumnos.

Published: October 2019

In general terms, methodology is a study of the entire scientific inquiry process: how science arrives at the posited goal. There are different kinds of goals for scientific inquiry. For example, goals may be epistemic (truth), aesthetic (simplicity) or several kinds of pragmatic goals (efficiency, economy, and explanatory power). It is not the concern of methodology what this goal happens to be. More generally, formal methods turned out to be effective tools in philosophical analysis, in the paper we will show this introducing the interrogative model and some basic properties of it, let us mention the covering law theorem. Finally we will formulate some philosophical implications of the model introduced.
Металогический плюрализм и универсальная логика
Authors: Васюков В.Л.
Published: October 2019

Концепция логического плюрализма утверждает, что есть не одна истинная логика, а их много. Концепция металогического плюрализма основана на предположении, что нет единственно правильного ответа относительно того, является ли данный аргумент дедуктивно правильным, но их много. Поскольку это приводит к взаимодействию между логикой и металогикой, возникает вопрос: какова природа этого взаимодействия? Подход Универсальной Логики дает нам намеки на некоторые ответы на этот вопрос. Есть также некоторые семантические ключи к рассматриваемой проблеме.

В статье мы представляем системы натурального вывода в стиле Фитча для некоторых логик с пресыщенными оценками и истинностными провалами. Мы показываем, что системы натурального вывода рассматриваемых логик могут быть заданы с различными формулировками либо правила исключения дизъюнкции, либо правила введения отрицания. Мы даем конструктивное доказательство того, что для каждой естественной системы выводов N логики $\alpha$ формула A доказуема в N тогда и только тогда, когда A является $\alpha$-теоремой.

Multiplying logical values
Authors: Малиновский Г.
Published: October 2019

The modern history of many-valuedness starts with Lukasiewicz’s construction of three-valued logic. This pioneering, philosophically motivated and matrix based construction, first presented in 1918, was in 1922 extended to n-valued cases, including two infinite ones. Soon several constructions of many-valued logic appeared and the history of the topic became rich and interesting. However, as it is widely known, the problem of interpretation of multiple values is still among vexed questions of contemporary logic. With the paper, which essentially groups my earlier settlements, from [3], [4], [7] and [8], I intend to put a new thread into discussion on the nature of logical many-valuedness. The topics, touched upon, are: matrices, tautological and non-tautological many-valuedness, Tarski’s structural consequence and the Lindenbaum–Wojcicki completeness result, which supports the Suszko’s claim on logical two-valuedness of any structural logic. Consequently, two facets of many-valuedness — referential and inferential — are unravelled. The first, fits the standard approach and it results in multiplication of semantic correlates of sentences, and not logical values in a proper sense. The second many-valuedness is a metalogical property of inference and refers to partition of the matrix universe into more than two disjoint subsets, used in the definition of inference.

Логический плюрализм и неклассическая теория категорий
Authors: Васюков В.Л.
Published: October 2019

Логический плюрализм оказывается гораздо более интригующим явлением, если мы обратимся к рассмотрению следствий логического плюрализма для элементарных логических теорий. Если мы откажемся от того, что в их основании лежит исключительно классическая логика, то мы оказываемся в области неклассических элементарных логических теорий, основанных на различных неклассических логиках. Это особенно важно, если учесть, что такие теории лежат в основе неклассических математик, по меткому выражению «существует столько математик сколько и логик», достаточно вспомнить релевантную арифметику, квантовую теорию множеств, нечеткую теорию множеств, паранепротиворечивую математику и др. В статье предлагаются неклассические аксиоматические теории категорий, основанные на некоторых неклассических категориальных структурах.
П.А. Флоренский о противоречии (логико-методологический анализ)
Authors: Герасимова И.А.
Published: October 2019

Антиномичность, мыслимая как самопротиворечивость, соединение тезиса и антитезиса в одно целое, в богословской традиции понимается как наилучший способ выражения целостности Божественной Истины. Этот вывод является общим местом для антиномичных стратегий разных религиозных традиций. Отражается ли понятие логического противоречия смысл антиномичности? Анализ текстов Флоренского приводит к мысли о необходимости различать аспекты логики, аргументации и риторики. Данное различие позволит адекватно исследовать религиозные тексты, опираясь на научную методологию.

Синтаксическая интерпретация категорических атрибутивных высказываний
Authors: Шалак В. И.
Published: October 2019

В статье предложен новый вид моделей для категорических атрибутивных высказываний. Эти модели могут быть названы синтаксическими, поскольку субъекту и предикату высказываний сопоставляются не экстенсионалы, а синтаксические определения, посредством которых эти термины вводятся в употребление. Построенные модели свободны от онтологических допущений. Связь между субъектом и предикатом интерпретируется не в терминах теоретико-множественных отношений между экстенсионалами, а в терминах логических отношений между дефиниенсами определений. Доказаны теоремы непротиворечивости и полноты фундаментальной силлогистики относительно синтаксических моделей.
On the ‘classical’ operations in three-valued logics
Authors: Девяткин Л. Ю.
Published: October 2019

The general aim of the present paper is to provide the analysis of the connection between proof-theoretical and functional properties of certain logical matrices. To be more precise, we consider the class of three-valued matrices that induce the classical consequence relation and show that their operations always constitute a subset of one of the maximal classes of functions, which preserve non-trivial equivalence relations. We use a matrix with the single designated value as a sample for in-depth analysis, and generalize the results to suit other cases. Furthermore, on the basis of obtained results we conclude the paper with methodological considerations concerning the nature and interpretation of the truth-values in logical matrices.
Секвенциальная аксиоматизация и семантика I-логик васильевского типа
Authors: Попов В. М.
Published: October 2019

Изучаемые здесь $I$-логики васильевского типа были найдены в процессе экспликации некоторых идей российского логика и философа Николая Александровича Васильева, лежащих в основе его «воображаемой логики». Целью этой статьи является демонстрация того, как конструировать простые и удобные для поиска доказательства секвенциальные аксиоматизации $I$-логик васильевского типа и как строить интуитивно ясные двузначные семантики, адекватные $I$-логикам васильевского типа. В предлагаемой статье определяются $I$-логики васильевского типа, строятся их секвенциальные аксиоматизации, даются необходимые семантические определения и доказываются теорема об оправданности $HI_{\langle\alpha,\beta\rangle}$-выводов (теорема 5) и теорема о полноте $HI_{\langle\alpha,\beta\rangle}$-выводов (теорема 6). Работа завершается рядом следствий из указанных теорем и анонсом решения проблемы табличности $I$-логик васильевского типа.

Published: October 2019

Based on the analysis of existing regulatory legal acts in the field of regulating the research activities of the member countries of the Eurasian Economic Union (EAEU), a conclusion was made about their similarity and the possibility of starting the operation of the single market of services (SMS) of research without adopting additional legal acts. A comparison of the sources of financing of science of the EAEU member countries with the average and best indicators in the world has been made. The average costs for the EAEU member country amounted to 0,43% of the gross domestic product (GDP) were 1,7% in the world (4 times more). In the EAEU, more research is carried out by public sector scientific organizations (31,8% in EAEU, 12,8% in the world), and less research is performed by the business sector. Proposals for the development of the EAEU SMS for the research, including the creation of the Science Fund and the Innovation Fund, the creation of an information resource on the websites of national regulators in the field of scientific activity, etc., have been made.

Published: October 2019

Based on literature review Three categories of teachers are: good, very good, and excellent which are viewed from aspects of beliefs, attitude, depth of pedagogical and didactic aspects, and teacher reflection in the learning process has been obtained in previous studies. Various external aspects are considered to affect teacher professionalism in learning about mathematical problem solving. These aspects need to be studied to maximize the teacher professionalism. This study will examine these external aspects, ranging from teaching experience, educational background, and experience in participating in training to improve teacher competencies. This type of qualitative research with survey methods was chosen as a research method. Three teachers from three junior high schools with different clusters were selected as research subjects. Each teacher is given short questions related to this. The results obtained are the experiences of the trainings that teachers follow in increasing their competence and teacher's educational background have more significant influence on teacher professionalism compared to the experience or length of teacher teaching.

Published: October 2019

Mathematical anxiety has a negative relationship with mathematics performance and achievement. Further explained, mathematics anxiety has an indirect effect on mathematics performance. This research explores sources or factors related to mathematics anxiety among engineering students at a private university in Indonesia. A total of 47 engineering students participated in this survey that randomly chosen based on gender, major, and age. Two main factors are affecting the mathematics anxiety of engineering students, namely internal and external factors. The results show that mathematics anxiety among engineering students is manifested into three aspects. Firstly, the home aspects are talking about the influence of parents and sibling. Secondly, society's issues are discussing self-efficacy, social reinforcement to hate mathematics, and social stereotypes. Lastly, the classroom aspects are talking about the traditional mathematics learning process and classroom culture, namely the experience of learning mathematics in classrooms and relationships between friends during learning. The details of the statements under the aspects also highlight unique problems and are not covered by previous research in mathematical anxiety. Next, differences in mathematics anxiety by gender and faculty were examined.

Oxygen metabolism has an important role in the normal functioning of reproductive system, as well as the pathogenesis of female infertility. Oxidative stress seems to be responsible for the initiation or development of reproductive organ diseases, including polycystic ovary syndrome, endometriosis, preeclampsia, etc. Given the important role of maintaining balance between the production of ROS and antioxidant defence in the proper functioning of reproductive system, in the present study we aimed to analyse the expression of genes related to oxygen metabolism in porcine oviductal epithelial cells during long-term in vitro culture. The oviducts were collected from 45 crossbred gilts at the age of approximately nine months that displayed at least two regular oestrous cycles. The oviductal endothelial cells were isolated by enzymatic digestion to establish long-term primary cultures. Gene expression changes between 7, 15 and 30 daysof culturewere analysed with the use ofwhole transcriptome profiling by Affymetrix microarrays. The most of the “cellular response to oxidative stress” genes were upregulated. However, we did not observe any main trend in changes within the “cellular response to oxygen-containing compound” ontology group, where the gene expression levels were changed in various manner.
