Металлы играют важную роль в регуляции физиологических процессов, но также могут оказывать потенциально токсические эффекты на организм человека. Никель, серебро, цирконий, стронций относятся к элементам, которые часто контактируют с кожными покровами или слизистыми оболочками человека. Определение биосовместимости или потенциальной токсичности материалов является недостаточно изученной и актуальной темой. Целью данной работы стало изучение связи концентраций никеля, серебра, стронция, циркония с уровнем С-реактивного белка (как неспецифического маркёра воспаления) в сыворотке крови, а также установление референсных значений концентраций перечисленных элементов в сыворотке крови при измерении методом ИСП-МС. Рассмотрены корреляции концентраций химических элементов с показателями С-реактивного белка в сыворотке. Исследование проводилось с использованием базы данных лабораторных анализов обследованных в возрасте от 18 до 93 лет. В сыворотке крови проанализированы уровни никеля, серебра, стронция, циркония методом ИСП-МС и уровень С-реактивного белка иммунотурбидиметрическим методом. В общей выборке выявлены cлабые, но статистически значимые корреляции серебра (r = 0,138, p <0,001) и стронция (r = 0,166, p <0,001) c С-реактивным белком. При разделении общей выборки по полу и возрасту наблюдались корреляции концентраций никеля, серебра, циркония, стронция с С-реактивным белком и среди мужчин, и среди женщин в возрастной группе 36‒45 лет (p <0,05). Таким образом, показано, что влияние ионов никеля, серебра, стронция, циркония на организм человека ассоциировано с повышением уровня С-реактивного белка в сыворотке крови и может оказывать провоспалительный эффект.

Authors: Demir Mehmet Raci , Yildizli Hülya
Published: September 2022

Due to the lockdown measures and severe restrictions taken to reduce COVID-19 transmission, which has globally been inflicted on people since March 2020, a new type of education in the form of online homeschooling has brought the role of parents to the forefront. Using online semi-structured interviews, this study aimed to investigate parents’ views on the implementation of distance education during COVID-19 in Istanbul, Turkey. The data obtained from parents with different socioeconomic backgrounds and whose children were at public and private schools were coded using initial, process, and emotion qualitative coding techniques. The data were categorized into three main themes: beginning of distance education, process of distance education, and outcomes of distance education. The beginning theme was further analyzed under three subcategories: problems related to the child, problems related to parents, and problems related to public schools. The problems encountered during the process of distance education were investigated under three subheadings: problems related to the child’s academic and social life, problems related to parents, and problems related to parent–child relationships. Data under the main theme, outcomes of distance education, were defined as positive or negative outcomes in terms of the child and parents. Results revealed that at the beginning of the process, during the process, and during the outcomes of distance education, parents experienced problems with digital technology, the new education model, teachers, themselves, and their children, as well as economic, social, and psychological problems. Parents also had various constructive suggestions about distance education during COVID-19.

Authors: Çakıroğlu Ünal , Saylan Esin , Çevik İsak , Özkan Adem
Published: September 2022

This quasi-experimental study explored how different online exam types differentiate learners’ academic achievement and perceived learning. The participants comprised 95 undergraduate students enrolled in an English course at a Turkish university in three groups, each taking a different type of quiz: with multiple-choice, open-ended, and mixed type questions. The results indicated that the academic achievement of the students in multiple-choice and open-ended groups increased and that quiz results improved the most for the multiple-choice group relative to the other groups. The study found a moderate level of significant relationship between cognitive and affective perceived learning and multiple-choice quiz scores. In addition, the study found a weak level of significant relationship between cognitive and affective perceived learning and mixed-design quiz scores, and between cognitive learning and the academic achievement scores of the mixed-design group. Semi-structured online interviews undertaken to further explain the quantitative data displayed positive influences of the different types of quizzes in terms of study behaviors and satisfaction. The findings of this study are expected to shed light for practitioners aiming to use different online assessment types.
Doing Open Science in a Research-Based Seminar: Students’ Positioning Towards Openness in Higher Education
Authors: Truan Naomi , Dressel Dennis
Published: September 2022

This study investigates undergraduate students’ attitudes towards and experiences with open education practices (OEP) in a research-based linguistics seminar. Data was collected through written assignments in which two groups of students in subsequent terms were surveyed on their willingness to publish (a) academic posters in open access (OA); (b) teaching concepts as open educational resources (OER); and (c) personal reflections on the research process in OA. Through qualitative data analysis, we examine students’ apprehensions and motivations to publish their artifacts. We find that key motivators are a sense of belonging, personal reward, and an active contribution to a culture of collaboration, whereas apprehensions are grounded in concerns about the quality of their work, uncertainties about licensing, and fear of vulnerability through visibility. We show that open science practices and OEP can be combined synergistically in process-oriented, research-based, and collaborative seminar concepts, and we formulate recommendations for lecturers on how to successfully address OEP in the classroom.

The heterogeneity of CAFs and immune cell populations in the tumor microenvironment of pancreatic adenocarcinoma
Authors: Diab Maria , El-Rayes Bassel F.
Published: September 2022

Over the past decade, researchers have identified and characterized the diverse cell populations within the tumor microenvironment of pancreatic cancer. The interplay between these cells in the TME either promotes or inhibits the malignant behavior of pancreatic cancer cells. Cancer-associated fibroblasts, previously thought to be one main subset, can now be broadly subclassified into three main types: inflammatory, myofibroblastic, and antigen-presenting, with the former and the latter two exerting pro-tumoral and anti-tumoral functions, respectively. Myeloid cells include myeloid-derived suppressor cells and tumor-associated macrophages. Myeloid-derived suppressor cells can be further divided into polymorphonuclear and monocytic and exhibit pro-tumoral activities. Tumor-associated macrophages exhibit M1 (anti-tumoral) or M2 (pro-tumoral) phenotypes, which are present in a dynamic fashion between the two phenotypes. Other constituents of the immune make-up of the tumor microenvironment include T and B cells and less described subsets which include natural killer cells, γδ T cells, and group 2 innate lymphoid cells. This review provides an overview of the studies that lead to the discovery of those cellular populations and highlights the recent efforts to utilize them as therapeutic targets in pancreatic cancer.

Mindannyiunk számára korábban teljességgel ismeretlen, új helyzeteket hozott a 2020 márciusában, a Covid-19 fertőzés kapcsán bevezetett szigorú kijárási korlátozás, pandémia. A lezárások és a személyes távolságtartás kényszere az élet számos területén újfajta, kreatív megoldásokat követelt meg. Ennek egy igen apró területét, a webes fejlesztések világát kutattam a lezárások idején, 2020 tavaszán. Arra voltam kíváncsi, hogyan alakul a tesztelések, kutatások menete négy, kifejezetten a Coviddal kapcsolatos felület – jellemzően otthonról menedzselt – tervezése-fejlesztése során. Látható volt, hogy a személyes találkozások lehetetlensége és nehézsége miatt, elsőként a felhasználói igényfelmérés és a tesztelés módja alakult át, mennyisége csökkent és az adatfelvétel módja is megváltozott. Üdítő kivétel természetesen itt is akadt.

Authors: Faqe Ibrahim Gaylan R. , Rasul Azad , Abdullah Haidi
Published: September 2022

Wheat and barley are among the primary food resources of the world population; therefore, their growth and observation are essential in farms to enhance food security worldwide. On top of that, careful observation of the product is essential to find solutions for the issues faced during their production and to reduce the impacts of weather changes. With the advancement of Remote Sensing technology, the observation and estimation process has increased. In this study, numbers of spectral vegetation indices was used along with canopy biophysical properties ( LAI ) and biochemical properties (chlorophyll), there calculated from (Landsat 8 and Sentinel-2) satellite data. The wheat and barley samples were collected before were be ready for harvest, and a relation with the vegetarian indices was established using the Multi-Linear Regression module, in which the equations used in predicting the harvest were developed and used to create a graph for expected harvest. The result indicated that there is a strong relationship between the vegetation indices of Sentinel-2 and Landsat images and the actual grain yield with R2 of 0.77 and 0.71, respectively. The results show that the strongest correlation is observed between the LAI data obtained from Sentinel data and cereal yield data, with an R2 0.68, and the highest correlation for the indices of Landsat images is observed in the NDWI with R2 0.59 and the lowest degree of error was in the root mean square error (RMSE) for the Sentinel-2 and Landsat 8 with 0.57 and 1.54. In addition, this study also showed that the least relationship for grain yield prediction was observed between the NDRI for Sentinel-2 (R2 0.1) and SAVI for Landsat image (R2 0.47).
Shielding Without a Shield – Older People during COVID-19 a Comparison of Four Cities
Authors: Wong Johnston , Ho Ghee Wee
Published: September 2022

As of July 7, 2022, the total number of confirmed cases caused by COVID-19 has reached 544,324 million, and the total number of 6.333 million deaths (WHO). Older people were globally the most vulnerable during the pandemic. This paper examined the mortality and psychological crisis of older people during the pandemic in four cities, namely Wuhan, Milan, London, and Hong Kong. The selection of cities was based on different degrees of social connectedness of older people and chronologically to cover the whole period of the outbreak from January 2020 to August 2022. Older people in Milan and Wuhan tended to rely on the close family relationship during times of crisis. Meanwhile, older people in Hong Kong and London were more dependent on social services. Both quantitative and qualitative approaches were employed to analyze the situations of older people under different government responses and the strengths and weaknesses of respective healthcare systems. Government reports and official statistics were used to illustrate the seriousness of each city's COVID-19 outbreak while stories reported by the press, NGOs, and journal articles were used to reflect the reactions of the older people. Interactions of social culture, health care provisions, and government responses to the pandemic were discussed from the perspective of health welfare regimes. On one hand, results showed that governments have not learned from the experiences of other countries. On the other hand, older people have not successfully coped with the life-threatening stress by breaking institutional boundaries and redefining cultural norms.
Refugee Appropriation of Inhospitable Urban Terrains: Learning from Jabar-Dakhal Colonies of Kolkata
Authors: Pal Shreyasi , Mitra Tapas
Published: September 2022

Refugee subject position is an evolving topic of contention in the world today with increased migrant and refugee mobilities. Urban refugee spaces are often segregated in the form of colonies, ethnic villages, even ghettos, embodying institutionalised discourses of apathy and violence. These spaces only occupy the cracks and margins of the normative, formal city, as appropriations of inhospitable natural terrains and urban systems. The paper discusses how refugees compete for resources for survival as “bio-political” subjects and are often held summarily responsible for causing ecological stress in host environments. After the 1947 Partition of the Indian subcontinent, millions of Hindu Bengali refugees from East Pakistan flooded the Eastern Indian states of West Bengal, Assam and Tripura. Kolkata particularly drew millions for better livelihood prospects. Facing government apathy and local violence, East-Bengali refugees appropriated the urban fringes of Kolkata and claimed their right to urban space through the political act of squatting or Jabar-Dakhal. The intent of this paper is to investigate and map the spatial distribution of East-Bengali refugee squatters and elaborate on how they transformed the terrain and distributed resources through self-management tactics. This spatial history case-study attempts to uncover locational data from archival government records, existing academic literature and fieldwork to visualise where the 145 pre-1950 and the 123 post-1950 Jabar-Dakhal colonies were located in the Kolkata Metropolitan Area. This case of successful refugee self-settlement is qualitatively read in relation to the major areas of ecological stress in Kolkata. One of the UN sustainable development goals is to make cities and human settlements ‘inclusive, safe, resilient and sustainable’. This paper hopes to encourage further studies of urban refugee self-settlement and local integration as a viable but complex socio-political-environmental process.

Antifungal agents are not always efficient in resolving vulvovaginal candidiasis (VVC), a common genital infection caused by overgrowth of Candida spp., including Candida albicans, or preventing recurrent infections. Although lactobacilli (which are dominant microorganisms constituting healthy human vaginal microbiota) are important barriers against VVC, the Lactobacillus metabolite concentration needed to suppress VVC is unknown. Therefore, we quantitatively evaluated Lactobacillus metabolite concentrations to determine their effect on Candida spp., including 27 vaginal strains of Lactobacillus crispatus, Lactobacillus jensenii, Lactobacillus gasseri, Lacticaseibacillus rhamnosus, and Limosilactobacillus vaginalis, with inhibitory abilities against biofilms of Candida clinical isolates. Lactobacillus culture supernatants suppressed viable bacteria by approximately 24%-92% relative to preformed Candida biofilms, but their suppression differed between strains, not species. Lactate production was necessary to suppress preformed biofilms and hyphal elongation of C. albicans, whereas hydrogen peroxide was not always essential. Both lactic acid and hydrogen peroxide were required to suppress Candida planktonic cell growth. Lactobacillus strains that significantly inhibited biofilm formation in culture supernatant also inhibited Candida adhesion to epithelial cells in an actual live bacterial adhesion competition test. Healthy human microflora and their metabolites may play important roles in the development of new antifungal agent against VVC caused by C. albicans.

We investigated whether a functional insertion/deletion (I/D) polymorphism of angiotensin-converting enzyme (ACE) influenced antipsychotic treatment. At baseline, and after 8 weeks of treatment with various antipsychotic medications, we assessed patients’ Positive and Negative Syndrome Scale (PANSS) scores, PANSS factors, and metabolic syndrome-related parameters (fasting plasma lipid and glucose levels, and body mass index). A total of 186 antipsychotic-naïve first-episode psychosis patients or nonadherent chronic psychosis individuals (99 males and 87 females) were genotyped by polymerase chain reaction analysis. The ACE-I/D polymorphism was significantly associated with changes in PANSS psychopathology only (p < 0.05). Compared to ACE-II homozygous males, ACE-DD homozygous and ACE-ID heterozygous males manifested significantly greater decreases in PANSS positive score, PANSS excitement factor, and PANSS cognitive factor. ACE-DD homozygous females manifested higher decreases in PANSS depression factor compared to ACE-II homozygous and ACE-ID heterozygous females. The polymorphism’s effect size was estimated as moderate to strong, while its contribution to the PANSS psychopathology ranged from ~5.4–8.7%, with the lowest contribution observed for PANSS positive score changes and the highest for PANSS depressive factor changes. Our results indicated that ACE-I/D polymorphism had a statistically significant but weak gender-specific impact on psychopathology data and showed no association between ACE-I/D polymorphism and metabolic syndrome-related parameters.
Informal Competition Effect on SMEs Innovation: Do Credit Constraints Matter? Evidence from Eastern European Countries
Authors: Hlioui Zaineb , Gabsi Mohamed , Omri Abdelwahed
Published: September 2022

This paper examines the influence of informal competition on SMEs innovation in the Eastern European transition economies. It investigates whether credit constraints mediate this relation. SMEs innovation is presented through four measures: Product innovation, Process innovation, Radical innovation and Green innovation. Using the BEEPs VI that covers the period from 2018-2020, we show that informal competition affects positively the product, process and radical innovation. Yet, it has a non-significant effect on green innovation. Besides, the informal sector increases SMEs credit constraints, which indirectly leads to less corporate innovation. The negative indirect effect restrains the positive direct effect. Hence, a partial mediation effect of credit constraints on the informal competition and the innovation proxies is reported with the exception of green innovation.

Authors: Thorp James A. , Rogers Claire , Deskevich Michael P. , Tankersley Stewart , Benavides Albert , Redshaw Megan D. , McCullough Peter A.
Published: September 2022

Objectives: Assess rates of adverse events (AE) after COVID-19 vaccines experienced by women of reproductive age, focusing on pregnancy and menstruation, using data collected by the US Centers for Disease Control and Prevention (CDC) Vaccine Adverse Events Reporting System (VAERS) database. Design: Population based retrospective cohort study. Setting: US and global entries in US Centers for Disease Control and Prevention (CDC) Vaccine Adverse Events Reporting System (VAERS). Participants CDC VAERS entries from January 1, 1998 to June 30, 2022. Interventions: None. Main Outcome and Measures: A proportional reporting ratio analysis is performed using data in the VAERS system comparing adverse events (AE) reported post COVID-19 vaccines with that of post-Influenza vaccines. Results: COVID-19 vaccines, when compared to the Influenza vaccines are associated with a significant increase in AE with all proportional reporting ratios of > 2.0: menstrual abnormality, miscarriage, fetal chromosomal abnormalities, fetal malformation, fetal cystic hygroma, fetal cardiac disorders, fetal arrhythmia, fetal cardiac arrest, fetal vascular mal-perfusion, fetal growth abnormalities, fetal abnormal surveillance, fetal placental thrombosis, low amniotic fluid, and fetal death/stillbirth (all p values were much smaller than 0.05). When normalized by time-available, doses-given, or persons-received, all COVID-19 vaccine AE far exceed the safety signal on all recognized thresholds. Conclusions: Pregnancy and menstrual abnormalities are significantly more frequent following COVID-19 vaccinations than that of Influenza vaccinations. A worldwide moratorium on the use of COVID-19 vaccines in pregnancy is advised until randomized prospective trials document safety in pregnancy and long-term follow-up in offspring.

O camarão pelágico, Acetes paraguayensis Hansen, 1919, é uma espécie ecologicamente importante, de enorme valor socioeconômico para as populações humanas localizadas nas regiões produtoras. Essa espécie tem também um potencial considerável para o cultivo, embora poucas informações sejam conhecidas da sua biologia. Assim o presente estudo investigou a exploração artesanal das populações de A. paraguayensis no municí­­pio paraense de Santarém, no Norte do Brasil, por 16 meses, concentrando-se nos tipos de equipamento mais utilizados para sua captura, na diní­¢mica pesqueira e nos padrões de produção. O matapi foi o principal método utilizado, configurando-se como um sistema de produção pesqueira tipicamente artesanal de pequena escala. Os resultados do presente estudo constituem importante instrumento de investigação para o desenvolvimento de estratégias de conservação e gestão e o eventual estabelecimento de protocolos de cultivo.

Published: September 2022

A hibridação é um fenômeno natural que ocorre mais frequentemente em peixes do que em outros vertebrados. Para detectá-la, são utilizados marcadores moleculares nucleares e mitocondriais, os quais fornecem resultados valiosos. O objetivo deste estudo foi investigar a ocorrência de hí­­bridos interespecí­­ficos em populações naturais de peixe-rei. As amostras de Odontesthes humensis, Odontesthes bonariensis e de indiví­­duos morfologicamente diferentes das espécies puras foram coletadas na lagoa Mangueira, localizada no Sul do Brasil. Foram sintetizados e testados seis loci microssatélites tetranucleotí­­deos. O locus UFPEL_OH3 mostrou-se um diagnóstico para detectar hí­­bridos de peixe-rei, possibilitando a distinção de espécies puras de hí­­bridas. O marcador mitocondrial gene cytb, sintetizado com base nas sequências conservadas de Odontesthes no banco de dados genéticos do GenBank, não apresentou diferenças na sequência genética das amostras, portanto, são necessários mais estudos para confirmar a hipótese de hibridação.

Published: September 2022

In this study, the effects of precipitation on Anomalocardia flexuosa densities were analyzed from the perspective of temporal delays between the variables. The collections occurred bi-monthly between April 2016 and February 2018 at Mangue Seco beach, Pernambuco, Brazil. Total densities and densities according to the category of size (small, medium and large), and precipitation were analyzed with autocorrelation and cross-correlation functions, with a retrospective analysis of up to 12 months. Distributed lag models were used among the variables. The maximum density was found in June 2017 (378 ind.m2) for the medium-size category of individuals. Significant autocorrelations occurred for densities (total and average size) and precipitation. In cross-correlation functions, high precipitation for a given month was followed by high densities of total and average individuals for up to two months. Distributed lag models also showed significant values between densities (total and medium-sized) and precipitation, which explained more than 50% of the variability of these two groups. The effect of precipitation was responsible for the increase in the density of A. flexuosa for up to two months, mainly by increasing individuals with medium shell lengths.

Authors: DİNÇSOY Leyla Burcu , KELECİOĞLU Hülya
Published: September 2022

In this research, the aim was to examine the effects of Markov Chain Monte Carlo (MCMC), multiple imputation (MI), and expectation maximization (EM), all methods of coping with missing data in mixed type tests including dichotomous and polytomous items, on the differential item functioning (DIF). The study was carried out on a complete data set consisting of the scores of 1160 students who took booklet number 9 in the science test in Trends in International Mathematics and Science Study (TIMSS) 2019 and answered it in full. The conditions to be examined for the effectiveness of the methods were missing data mechanism (MCAR and MAR), DIF level (A, B, and C), and missing data rate (10% and 20%). Data were assigned to the missing data sets created by deleting data at different rates under the missing completely at random (MCAR) and missing at random (MAR) mechanisms over the aforementioned data set. DIF analysis was performed on all the data sets obtained with the poly-SIBTEST method using the MCMC, MI, and EM methods. The results obtained from the complete data set were then compared with the result implications from other data sets for reference. The study showed that the EM and MCMC methods performed better for the C-level DIF than the A and B levels in terms of all conditions examined. MI was observed to be the most successful method in determining DIF in items showing DIF in 10% and 20% MCAR mechanisms. When compared with the complete data set, the three methods showed similar results in the 10% MAR mechanism while MCMC gave the closest results in the 20% MAR mechanism.

Published: September 2022

En este estudio se realiza la caracterización genética de la raza canina Ca Rater Mallorquí, cuya función original era la caza de pequeños mamíferos. El objetivo es analizar la diferenciación genética intraracial e interracial, comparando esta raza con otras razas con la misma distribución y que comparten o no la misma funcionalidad. En el estudio intraracial, se analizan 33 microsatélites recomendados por la Sociedad Internacional de Genética Animal (ISAG), en 79 muestras obtenidas de varios propietarios de la isla de Mallorca. Para el estudio de la diversidad genética interracial, se utilizan datos de 275 muestras procedentes de 5 razas caninas de las islas Baleares: Ca Mè Mallorquí, Ca de Bou, Ca de Bestiar, Ca de Conills de Menorca y Ca Eivissenc (Podenco Ibicenco). Se lleva a cabo la extracción siguiendo el método de Walsh. Se amplifican los microsatélites mediante PCR y la detección de polimorfismos se hace con un secuenciador automático capilar. La población no muestra una desviación significativa del equilibrio Hardy- Weinberg, con una HO de 0,656 y una HE de 0,685. El estadístico FST, mostró que un 13,10% de la diferenciación genética se debe a diferencias entre razas. El análisis de la estructura genética evidenció la diferenciación del Ca Rater Mallorquí del resto de las razas, sin subestructura evidente. Como conclusión, el Ca Rater Mallorquí muestra una elevada diversidad genética, es una raza definida y genéticamente homogénea que no muestra signos de cruzamiento con el resto de las razas incluidas en el estudio. Estos resultados proporcionan un conocimiento esencial de la situación genética del Ca Rater Mallorquí y es un punto de partida para el diseño e implementación de un plan de conservación de la raza.

Authors: Pereira dos Santos e Araújo P.
Published: September 2022

A recuperação de áreas de pastagens degradadas baseia-se na utilização eficiente da gramínea forrageira visando minimizar a interferência das plantas daninhas. Objetivou-se avaliar o efeito de densidades de semeadura na variação populacional de plantas daninhas sob condição de reforma de pastagem cultivada de Urochloa brizantha cv. Marandu. Adotou-se o delineamento experimental em blocos casualizados, com quatro repetições e os tratamentos constituídos de cinco densidades de semeadura: 0%, 25%, 50%, 75% e 100% estabelecidas em função da recomendação de uso do capim-marandu (15 kg ha-1) baseado no valor cultural (60% de pureza e 60% de germinação). A identificação e quantificação das plantas daninhas foram realizadas aos 7, 14, 21, 28, 35, 42 e 49 dias após a emergência (DAE). A matéria seca das plantas daninhas foi obtida aos 49 DAE e as parcelas foram avaliadas quanto as características estruturais e produtivas da forrageira. Com os dados de matéria seca das plantas daninhas determinou-se a importância relativa pelo índice de valor de importância das espécies do estudo. Os resultados foram submetidos a análise de variância, e quando significativos realizou-se análise de regressão. Verificou-se redução gradativa no número total de indivíduos m-2 da comunidade infestante de acordo com o aumento na densidade de semeadura, chegando à 55% de redução na densidade de semeadura de 75% aos 42 DAE. A competição entre as espécies estabelece-se logo no período inicial de convivência e contribui para a baixa produção de matéria seca do capim-marandu semeado à 25% da recomendação de uso.

Published: September 2022

El presente trabajo de revisión bibliográfica, exhibe el mecanismo de acción, modo de empleo, dosis utilizadas y beneficios demostrados por Saccharomyces cerevisiae en animales de producción comercial. Varios estudios demuestran que la levadura se utiliza en diferentes dosis y concentraciones como cultivo (probiótico) o sus paredes celulares (prebiótico), atribuyendo impacto positivo de S. cerevisiae sobre los parámetros productivos y reproductivos de los animales, incremento en la digestibilidad de nutrientes, mejoras sobre las variables de morfometria intestinal, regulación del pH ruminal, modulación de la población microbiana, beneficios en el sistema inmunológico, disminución en la concentración de amoniaco, entre otros; no obstante, se debe considerar que la acción benéfica de la levadura difiere por el pH, temperatura de extracción, composición nutricional, cepa utilizada, dosis, concentración, modo de empleo y por la diversidad de dietas ofrecidas a los animales. Los resultados obtenidos en investigaciones recientes conllevan a concluir que, el uso de Saccharomyces cerevisiae como aditivo en la alimentación animal puede sustituir a los antibióticos promotores de crecimiento, logrando similares resultados a los APC, sin dejar residuos en los productos y subproductos de los animales que resulten perjudiciales al consumidor.
