Authors: Ólafsdóttir Anna Hulda , Ingason Helgi Þór
Published: January 2022

Greinin er byggð á meistaraverkefni Önnu Huldu Ólafsdóttur í iðnaðarverkfræði við Háskóla Íslands árið 2011. Helsta markmið verkefnisins var að skoða áhrif gæðastjórnunar á mannvirkjagerð en sérstök áhersla var lögð á að skoða áhrif gæðastjórnunar á verkkaupa og sér í lagi hvort marktækur munur væri á ánægju verkkaupa með framkvæmd verka hjá verktökum sem störfuðu eftir gæðastjórnunarkerfi miðað við verktaka sem ekki störfuðu
eftir gæðastjórnunarkerfi. Spurningalisti var lagður fyrir verkkaupa og verktaka og og gögnin notuð til að mæla fylgni milli ánægju verkkaupa með framkvæmd verks hjá verktaka við þætti úr könnun verktaka, eins og hvort hann starfar eftir gæðastjórnunarkerfi. Helstu niðurstöður eru að marktækur munur og sterk fylgni mældist milli
ánægju verkkaupa með framkvæmd og hvort verktaki starfar eftir gæðastjórnunarkerfi. Einnig sýna niðurstöður að þeir verktakar sem segjast starfa eftir gæðastjórnunarkerfi beita markvissari og skilvirkari vinnubrögðum en þeir sem starfa ekki eftir slíku kerfi.

The paper is based on Anna Hulda Ólafsdóttir's master's thesis conducted in Industrial engineering at the University of Iceland in 2011. The objective of the thesis was to examine the effect of quality management system (QMS) in the Icelandic construction industry. Particular emphasis was placed on examining how quality
management affects the client and whether differences exist in client satisfaction with regard to project execution depending on whether the project involved is completed by contractors that
work in accordance with a quality management system. Also to examine whether there is a discernable difference in the working methods of those contractors who claim to work in accordance with a QMS compared to those who do not. A questionnaire was designed and circulated among clients and contractors in an effort
to answer these questions. The main conclusions drawn from the thesis were that there is a strong correlation between client satisfaction with a project's execution depending on whether or not the contractor conducts his operations in accordance with a QMS. It was also concluded that those contractors who claim to conduct their operations in accordance with a QMS employ much better aimed and effective working methods compared to those contractors who do not.

Markmið þessarar rannsóknar var að meta hvort „meira er betra“ gildi fyrir sambandið milli verkefnaálags og prófseinkunnar annars vegar og verkefnaálags og ánægju nemenda hins vegar. Einungis var metið verkefnaálag sem tengdist lokaprófi; þ.e., ekki var tekin með vinna sem tengdist tölvuverkefnum sem gáfu hluta af lokaeinkunn og ekki var prófað úr. Verkefnaálagið var metið með því að mæla hversu lengi það tók kennara
að leysa vikulegu heimaverkefnin. Ánægja nemenda var metin í árlegu kennslumati námskeiðsins. Einkunnirnar sem voru notaðar voru eingöngu úr skriflegu prófi (ekki vinnueinkunn né lokaeinkunn). Niðurstöður rannsóknarinnar leiddu í ljós að það er ekki marktækt samhengi milli verkefnaálags og prófseinkunnar né verkefnaálags og ánægju nemenda.

The purpose of this study was to evaluate whether the general assumption of ‘more is better' is valid for the relation between workload and the final results, i.e. grades and satisfaction. Only the workload related to
assignments was estimated as the other workload did not change. The workload was estimated by measuring the time it took the lecturer to solve the homework assignments and the student satisfaction was estimated by
using results from annual student ratings made each year. The grades used were from the final exams only, not the final course grade. The results reveal that there are no relations between the workload, final exam grade and satisfaction, when compared two by two (workload vs. grade, workload vs. satisfaction and grade vs. satisfaction).

Authors: Azarova N. , Shlapak N. , Harbazhiy K.
Published: January 2022

The aim of the current work was to develop a recipe of meat-and-vegetablechopped semi-products of the new generation based on turkey meat and champignon mushrooms and to investigate its quality. The samples of turkey meat withthe addition of champignon mushroom mass were prepared and studied. Physicalchemical methods including determination of the mass fraction of moisture, water-retaining ability, weight losses during heat treatment, determination of maximum shear stress and the content of sodium chloride. The organoleptic analysiswas based on identification of taste, odor, consistence and view on the cut andwere used in order to characterize the quality of new semi-products from turkeymeat and champignon mushrooms. Studies have shown that the addition of mushroom mass to model minced meat from turkeys lead to an increase in the massfraction of moisture in the samples, as the moisture content of the mushroom isgreater than in turkey meat. The water-retaining ability in the model samples isreduced, which is associated with an increase in moisture in the specimens withadding of mushroom mass. The consistency of the specimens was determined bya penetrometer using a conic cone. It was determined that the consistency of themodel samples with the addition of mushroom mass become softer. The pH of thesample forcemeat significantly did not change. Analysis of the data that has beenobtained showed that the addition of mushroom mass leads to the destruction ofmeat parsley systems and reduce their functional and technological properties.Based on the results of the research, it was concluded that the most rational way isto replace up to 3 % of the turkey meat with the mass of champignon mushroomwithout the practical reduction of the organoleptic parameters in the formulationof the cut semi-finished products.
Key words: turkey meat, mushroom, champignon, cutlets, semi-products,functional and technological properties.

Published: January 2022

The paper deals with Bahachansky type breeding that has been carried out in “Ukraine” farm business, Velyka Bahachka Region, Poltava District. The studies evaluated breeding boars that represent the most numerous interbreed type lines. The breeding boars were evaluated by the quality of the offspring by fattening performance test and estimates based on probit indices. The findings evaluation of the boars according to the fattening and meat qualities of the offspring showed that the descendants of Yola 30581 and Kyuukka 30077 boars had the lowest fat depth (-2.15%, compared to the average level by the groups). At the same time, the offspring of boars Gültor 29997 and Denny 30939 distinguished themselves with the highest live weight at the age of 7 months (+2.4% and +1.92% compared to the average level of the group). It was found that there is a moderate correlation between the signs of fat depth and the average daily gain: -0.31 ± 0.137 (p <0.05). This nature of the correlation will facilitate the breeding, and will provide an opportunity to obtain animals with the largest possible average daily gain and lowest possible fat depth. According to the conducting of breeding work on the fat depth, the variability level was taken into account. It was found that the descendants of Kyuukka 30077 boar had the highest variability level on this basis (higher than the average of the sample by 0.82 percentage points). Evaluation of breeding boars by offspring quality using probit indices showed that the offspring of Gültor 29997 and Denny 30939 boars predominated in terms of live weight at the age of 7 months, in addition, the descendants of Denny 30939 boar were also better in terms of fat depth. It was established that the descendants of Gültor 29997 boar have probably better tenderness of meat in terms of quality. The descendants of Yola 30235 boar are notable for moisture-retaining ability, and the lowest costs of heat treatment were recorded for the descendants of the Tyke 30103 boar. Thus, the quality of meat is significantly affected not only by the level of feeding but also the genotype of the animal.

The Simulation of the dynamics of 137Cs accumulation by freshwater fish
Authors: Volkova O. , Belyaev V. , Skyba V. , Pryshljak S.
Published: January 2022

The study aimed to simulate the dynamics of 137Cs accumulation by freshwater fish under conditions of hypothetical radioactive contamination of water reservoirs in different seasons. The subject of research is the regularities of 137Cs accumulation by non-predatory fish species in eutrophic and oligotrophic water bodies. The dynamics of the 137Cs content in freshwater fish was calculated according to the content of radionuclides in water masses. The results of modeling the volumetric activity of 137Cs in water masses were used as an input parameter for the radionuclide accumulation in fish model. The fish organism was represented in the form of 3 independent related only by the balance equation; seasonal changes in the fish feeding intensity were taken into account in the modeling. The parameter that takes into account the contribution of the feeding intensity to the process of 137Cs intake into the fish organism has been determined. The features of the dynamics of 137Cs accumulation in eutrophic and oligotrophic water bodies fish are analyzed for cases of a hypothetical accidental input of 137Cs into ecosystems at the beginning of different periods of the annual life cycle of fish: 1st - from 1 to 31 March; 2nd - from 1 to 30 April; 3rd - from May 1 to September 19; 4th - from September 20 to October 19; 5th - from October 20 to November 30; 6th (freeze-up period) - from December 1 to February 28. The study has found that for a eutrophic water body the highest levels of 137Cs content in peaceful fish will be formed in the case of 137Cs entering ecosystems in spring (options 1–3). The maximum levels of 137Cs content in fish will be observed in the contamination period mentioned in option 3. Under hypothetical pollution in the autumn-winter period (options 4–6), the levels of 137Cs in peaceful fish will be approximately 2 times lower than in the case of pollution of the reservoir in spring. It has been found that the maximum value of the specific activity of 137Cs in fish from an oligotrophic water reservoir is not related to the season of pollution. However, the levels of fish pollution in the oligotrophic reservoir will be 1.5–2 times higher than those of the eutrophic one in options 1–3 and 3–4 times higher in options 4–6 . In the event of an emergency density of 137Cs fallout at the level of 4 kBq /m2 on the surface of different types of closed water reservoirs, its specific activity in peaceful fish will exceed the currently established permissible levels of fish products contamination. If the fallout density is twice as low (2kBq/ m2), the accumulation levels 137Cs by fishes of eutrophic water bodies will exceed the permissible standards in case of emergency inflows in spring. For oligotrophic water reservoirs, the guaranteed non-excess of the established standards in fish products is possible if the 137Cs fallout density is under 0.5 kBq /m2.
Key words: fish, modeling, 137Cs, specific activity, hypothetical pollution, reservoirs of different trophic status.
The Influence of genotypic and phenotypic factors on indicators of cow comfort
Authors: Borshch O.
Published: January 2022

The aim of this article is to summarize the available knowledge about the effects of temperature stress on cow health, productivity and comfort levels, and to discuss management strategies that would mitigate these factors. he study of the influence of weather phenomena on behavioral and physiological processes takes an important place in the development of highly effective methods for managing dairy cattle breeding. Climate and weather factors have become important in the system of interaction «organism-environment». One of the main factors in increasing the comfort indicators of conditions for keeping cows in premises of various types, on walking grounds and on pastures is the creation of such microclimate indicators that would better correspond to the biological needs of dairy cows, depending on the season and productivity. Among the weather factors affecting the functioning of dairy cattle, the ambient temperature has the greatest influence, (the temperature in the range from -5 to 25 °C is thermally neutral for the organism of dairy cattle). Due to the constancy of metabolic processes, the body of cattle is very vulnerable to the effects of ambient temperature. This is especially felt during periods of prolonged low or high temperature loads. Disruption of metabolic and thermoregulatory processes directly affects the duration and nature of behavioral and physiological reactions and causes stress in animals. Prolonged temperature stress is the cause of fluctuations in productivity indicators, the qualitative composition of milk, problems with reproduction and, taken together, significantly affects the profitability of production. To reduce the effect of temperature stresses on the body of dairy cows, scientists have proposed management strategies during periods of high and low temperature loads. These strategies divided into genotypic: selection of temperature resistant individuals of different breeds and phenotypic: the use of microclimate control means and modernization of feeding management methods.
Key words: cows, temperature stresses, productivity, comfort, behavior, housing options.

Purpose: To compare the degree of meibomian gland drop-out associated with Demodex infestation using non-contact meibography.Methods: We performed noncontact meibography using an infrared digital camera on 24 adult subjects infested by Demodex and 40 without infestation. The right upper and lower lids were scored based on the loss of meibomian glands, and the scores of the upper and lower eyelids were summed to obtain the total meiboscore for each subject. Meiboscores were evaluated according to Demodex infestation and gender in each group.Results: Sixty-four eyes of 64 people were enrolled in this study. The study subjects had an average age of 67.9 years (range, 40-79 years; men, 65.2 years; women, 69.1 years). There was a significant association between Demodex infestation and total meiboscore and upper and lower eyelid meiboscores (p = 0.000, p = 0.002, p = 0.004, respectively). There was no significant difference in the meiboscores between men and women. Age and meiboscore suggested a weak positive correlation; however, the R2 value was low, due to the concentrated age distribution of the study population.Conclusions: Based on noncontact meibography, the authors concluded that the prevalence of changes in the meibomian glands was significantly related to Demodex infestation; however, there was no significant difference between men and women.

Hölderlin’s Mythopoetics: From ‘Aesthetic Letters’ to the New Mythology
Authors: Fischer Luke
Published: January 2022

This essay reconstructs the relationship between Hölderlin’s philosophical aesthetics and the mythological dimensions of his mature poetry (circa 1800). It traces how Hölderlin expanded Schiller’s ideas about the harmony of beauty to the Absolute and transformed Schiller’s views of aesthetic education, and its societal significance, into the programme of a new mythology. In doing so, Hölderlin both made a crucial contribution to developments within post-Kantian philosophy and established the theoretical basis for the mythopoetry of his great elegies and hymns, which are the highest embodiment of his philosophical aesthetics. In contrast to Hegel’s mature system, in which it is only philosophy that can resolve the oppositions of modernity, Hölderlin held the view (similarly to Schelling) that these oppositions – especially the opposition between nature and spirit – could only be resolved in the form of a new, syncretic mythology. The essay explicates various texts by Hölderlin, including letters, essays, the novel Hyperion, the elegy ‘Bread and Wine’ and the hymn ‘Celebration of Peace’. It also argues for the relevance of Hölderlin’s mythopoetic vision to our contemporary situation of ecological crisis.
‘I wants to awaken yer bloody clarss consciousness’: Gothic Marxism in Eugene O’Neill’s The Hairy Ape
Authors: Sauskojus Kelly
Published: January 2022

American playwright Eugene O’Neill’s The Hairy Ape stages the vast distance between classes, or what Karl Marx terms alienation, as a Gothic narrative, where two wildly different characters – Yank, a rough, violent stokerman in the bowels of an ocean steamer, and Mildred, a bored, anemic society girl from the top decks – confront and interpret each other as lifeless, inhuman monsters, both destructive and incomprehensible. By situating the characters in their social and material contexts, this new Gothic reading takes into account the text’s central concern of class conflict while acknowledging the limits of a purely Marxist interpretation. Instead, this reading maintains the tension between its overlapping ideas about the divisions wrought by class, labor, and economic systems, and the failures of modern rationality to address or even describe the resulting horrors stemming from laborers’ alienation from their labor, themselves, and other humans.
Toward an Ecologically Harmonious Modernity: Nature Writing in Contemporary Chinese Ethnic Minority Children's Literature
Authors: Jiang Shuqin
Published: January 2022

Zhongguo dangdai shaoshu minzu ertong wenxue yuanchuang shuxi [A contemporary Chinese ethnic minority children's literature series] is a collection of ten novels published in 2017 describing the life of young children from a variety of ethnic minorities. Ethnic minorities in China generally live in rural areas and hold holistic and animistic world views. While this series contains abundant descriptions of distinctive landscapes and animals, these natural elements are not meant to be mysterious or sacred, but a tangible part of everyday life. The nature writing in the series plays with new possibilities and manifests a shift from a transcendent and metaphysical worldview to one that is epistemologically imminent and empirical, which suggests the new generation's readiness to embrace modernity in an ecologically harmonious way.
The Politics of Aesthetics of Tara Books'The London Jungle Bookby Bhajju Shyam
Authors: Singh Shikha
Published: January 2022

This article discusses the conditions surrounding the production and reception of Pardhan-Gond art as book illustration and visual narrative in Bhajju Shyam's The London Jungle Book (2004). It argues for the need for new frameworks and approaches to understand the poetics and politics of the narrative which depend on the visual art by the artist, as well as the paratextual elements of the print form and the collaborative-creative process of publishing. While the narrative makes an important argument regarding the social structures and power relations affecting the production and reception of non-western art forms in the west, the form of the narrative also holds important clues for understanding and experiencing the unique conditions of the production and adaptation of the art form as crossover picturebook.

El uso de la tecnología en el área de la salud contribuye al diagnóstico y tratamiento de casi cualquier patología laríngea, incluida la parálisis unilateral de las cuerdas vocales. La videolaringoscopia de alta velocidad es una técnica que captura el verdadero comportamiento vibratorio intraciclo de las cuerdas vocales. Las cámaras de alta velocidad pueden grabar velocidades de cuadros de hasta 4000 cuadros por segundo y generar una gran cantidad de datos laríngeos. Por otro lado, la minería de datos es un proceso de exploración de datos capaz de identificar patrones entre la información y agruparlos de acuerdo con algunos criterios dados. Objetivo: identificar, a través de un sistema de minería de datos computarizado, los criterios para el análisis de imágenes laríngeas y señales acústicas de voces con y sin parálisis unilateral de cuerdas vocales. Metodología: las imágenes laríngeas transformadas en quimiografía de alta velocidad y señales acústicas de voz de sujetos con y sin parálisis unilateral de cuerdas vocales capturadas por videolaringoscopia de alta velocidad fueron analizadas por un sistema de minería de datos computarizado, el SISTEMA DAMICORE. Resultados: para la quimiografía de alta velocidad de individuos sanos, el sistema de minería de datos encontró el sexo como un criterio de recopilación, mientras que las imágenes de los sujetos con parálisis unilateral de cuerdas vocales se obtuvieron mediante un contraste de colores, ya sea por la mucosa laríngea o por incidencia de luz en las imágenes . Con respecto a las señales acústicas de voz, la técnica consideró la presencia de ruido externo como un criterio para reunir a ambos grupos. Conclusión: Llegamos a la conclusión de que DAMICORE era una herramienta eficaz para la extracción de datos laríngeos y vocales, y era más sensible a las imágenes grupales que a las señales acústicas de voz.

Atención Fonoaudiológica Vocal a Actores: La Opción (o necesidad) de Aportar en la Promoción de su Bienestar Vocal-Emocional
Authors: Azocar Fuentes María Josefina
Published: January 2022

En voz, la fonoaudiología se dedica a la rehabilitación y habilitación vocal. Desde una perspectiva biopsicosocial, debiese enfatizar en ambos contextos, en la salud y bienestar comunicativo a partir de la voz.

En ese contexto, el propósito de este artículo es hacer una reflexión en torno a las posibilidades que tiene la fonoaudiología de generar espacios de exploración vocal-emocional en instancias de habilitación vocal con la intención de enriquecer la construcción de sí mismo del artista, favoreciendo su salud, bienestar y desarrollo profesional. Para ello, se expone teóricamente a los conceptos de ser y bienestar en la salud y la actuación, como marco para proponer que la habilitación vocal puede ser un espacio para profundizar en el conocimiento y la expresión de sí mismo, favoreciendo la calidad de vida y la creación escénica del Performer (salud en actividad y participación).

Lo anterior repercute en dos líneas como responsabilidad ética: la necesidad de formación del fonoaudiólogo de voz como acompañante/guía de una proceso que apunta más allá del abordaje de aspectos técnico-vocales y la necesidad de generar evidencia del enfoque propuesto desde la vereda disciplinar.

La electroestimulación neuromuscular tiene como finalidad promover el movimiento del complejo hiolaríngeo y favorecimiento de los grupos musculares envueltos directamente en la deglución, de ahí la importancia de sustentar conceptual, teórica y procedimentalmente la técnica para en la atención del Fonoaudiólogo. Metodo: la revisión sistemática fue basa en la metodología Prisma, se consultaron las bases de datos Scielo, Lilacs y PubMed, utilizando los descriptores “Deglución”, “Accidente Vascular Cerebral”, “Disfagia”, “Electroestimulación”, “Efectos” (Swallowing, Stroke, dysphagia, electrostimulation, Effects). Resultados: fueron encontrados 79 estudios relacionados con los descriptores utilizados, 13 estudios cuando los descriptores se relacionaban con la técnica de Electroestimulación Funcional. La mayoría de los estudios seleccionados y revisados mostraron efectos beneficiosos como resultado de la terapia tradicional combinada con la EENM, estos efectos fueron: cambios significativos a nivel de ingesta por via oral, mayor significancia en la escala de penetración y aspiración con disminución en el tiempo de transito oral y faríngeo de la deglución. Conclusiones: Los estudios indagados mostraron que la EENM es una herramienta eficaz cundo se utiliza de manera complementaria con la terapia tradicional para la disfagia en casos de ACV.

Authors: Vargas Garcia Miguel Antonio , Bustamante Arboleda Valeria , Ospina Ruiz Ana , Valvuena Cuartas Catalina
Published: January 2022

La presente revisión se planteó con el fin de recopilar la evidencia existente sobre el abordaje rehabilitador de la disfagia en adultos mayores con enfermedades neurodegenerativas, con la intención de encontrar propuestas de tratamientos que influyan de manera positiva en la salud de los pacientes. Los métodos de búsqueda se implementaron bajo un proceso ordenado de revisión sistemática bajo el modelo Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), a través de la cual se recolecta información de forma cronológica sobre la evidencia científica de un tema en particular. Para ello se usaron descriptores como: “Adulto; Neurodegenerativa; Disfagia; Rehabilitación”. En la revisión sistemática se incluyeron 21 artículos, entre estos se mencionaron estudios y revisiones sobre los tratamientos empleados en las enfermedades neurodegenerativas. En los hallazgos es evidente la intervención multidisciplinar, modificación del entorno, uso de fármacos como medio para mitigar síntomas principalmente motores, procedimientos quirúrgicos; además, maniobras deglutorias, compensatorias, rehabilitadoras, entre otras. Algunas alternativas requieren de la participación del Fonoaudiólogo/Logopeda debido a que en la mayoría de personas que padecen enfermedades neurodegenerativas se ve afectada la fase oral y/o faríngea de la deglución, desencadenando disfagia en diferentes grados de severidad y comprometiendo de forma directa la ingesta de alimentos debido al riesgo de aspiración, neumonía y/o muerte y a su vez, la calidad de vida. Esta revisión sistemática permite identificar la necesidad de realizar más propuestas terapéuticas, estudios que evidencien su eficacia y que, sobre todo, generen cambios significativos en quienes padecen las enfermedades descritas.

Published: January 2022

Dentro de la atención clínica, el profesional de la fonoaudiología cuenta con recursos evaluativos para describir la biomecánica secuencial de la ingesta; uno de los recursos utilizados es la Auscultación Cervical (AC). Teniendo en cuenta la descripción de la importancia de la intervención oportuna y efectiva de los procesos de alimentación en los niños con parálisis cerebral, se considera necesario resolver ¿cuál es el perfil espectrográfico que registra la fase faríngea de la deglución en el paciente pediátrico con parálisis cerebral? Su metodología contempla una Revisión sistemática bajo metodología PRISMA, estableciendo la búsqueda de artículos científicos en la utilización de la AC en la evaluación clínica de la deglución en sujetos pediátricos diagnosticados con Parálisis Cerebral. Como resultado se hallan 180 artículos en las bases de datos indagadas, tomando de acuerdo a los criterios de elegibilidad 6 artículos del total, estableciendo un 3,34% de inclusión. En ausencia de procesos instrumentales de evaluación deglutoria, la AC aporta como beneficio la accesibilidad del procedimiento, además de características de temporalidad en la secuencia de los sonidos deglutorio, sin ningún tipo de factor adverso para su realización. Es por ello que la auscultación es un recurso importante en la evaluación clínica, establece un primer paso en el análisis fisiológico de la deglución con los aspectos fisiológicos de la fase faríngea. Esto, pone a la auscultación en una posición privilegiada, pero que debe ser estandarizada por los estudiosos y teóricos del tema.

El propósito de este estudio fue determinar las diferencias en el rendimiento de las habilidades cognitivas entre 25 consumidores de cigarrillo y 25 consumidores de cannabis de 18 a 30 años (ambos grupos corresponden a estudiantes universitarios) y correlacionar su desempeño con el tiempo y frecuencia de consumo. Este estudio de tipo cuantitativo, no experimental-transversal, cuyo alcance fue descriptivo, comparativo y correlacional, evidenció que los consumidores de cannabis presentaron resultados significativamente menores en cada una de las habilidades cognitivas, especialmente en las funciones ejecutivas, siendo la habilidad que presentó peor desempeño en ambos grupos. Por otro lado, la habilidad que presenta una menor brecha entre los grupos es el lenguaje, habilidad que mostró tener un mejor rendimiento en los consumidores de marihuana en comparación con las demás habilidades. A pesar de los hallazgos, no fue posible establecer la relación entre el déficit de dichas habilidades y el tiempo y la frecuencia de consumo en ningún grupo debido a que la muestra estaba constituida por consumidores recientes. Se concluye que ambos tipos de consumo influyen en el déficit de las habilidades cognitivas a corto plazo, por lo cual es importante que equipos multidisciplinarios de profesionales especializados en el área de la salud consideren acciones de prevención e intervención en aquellos pacientes jóvenes que abusan del consumo tanto de sustancias lícitas como ilícitas con el fin de minimizar los efectos tanto en la salud física como en la cognitiva en la edad adulta.

Yeast cells suffer from continuous and long-term thermal stress during high-temperature ethanol fermentation. Understanding the mechanism of yeast thermotolerance is important not only for studying microbial stress biology in basic research but also for developing thermotolerant strains for industrial application. Here, we compared the effects of 23 transcription factor (TF) deletions on high-temperature ethanol fermentation and cell survival after heat shock treatment and identified three core TFs, Sin3p, Srb2p and Mig1p, that are involved in regulating the response to long-term thermotolerance. Further analyses of comparative transcriptome profiling of the core TF deletions and transcription regulatory associations revealed a hierarchical transcriptional regulatory network centered on these three TFs. This global transcriptional regulatory network provided a better understanding of the regulatory mechanism behind long-term thermal stress tolerance as well as potential targets for transcriptome engineering to improve the performance of high-temperature ethanol fermentation by an industrial Saccharomyces cerevisiae strain.

The activation of hypoxia-inducible factor 1α (HIF-1α) signaling has promising implications for the treatment of bone diseases such as osteoporosis and skeletal fractures. However, the effects of manipulating HIF-1α pathway on bone micro-structure and remodeling should be fully studied before the clinical application of therapeutics that interfere with the HIF-1α pathway. In this study, we found that osteocyte-specific HIF-1α pathway had critical role in manipulating bone mass accrual, bone material properties and micro-structures, including bone mineralization, bone collagen fiber formation, osteocyte/canalicular network, and bone remodeling. In addition, our results suggest that osteocyte-specific HIF-1α pathway regulates bone micro-structure and remodeling via impairing osteocyte differentiation and maturation.

Ferroptosis is an iron-dependent regulated cell-death caused by the accumulation of lipid peroxides, which is different from apoptosis, autophagy, necroptosis and other forms of regulatory cell death in morphology and mechanism. It has attracted interest and attention of scholars from all over the world during the past years. Recent studies have shown that ferroptosis is able to play a clear and important role in cancer treatment, providing a bright prospect for targeted cancer therapy. This article aims to analyze current scientific results about the application of ferroptosis in the field of cancer treatment, providing new ideas for further research. We retrieved publications related to ferroptosis and cancer treatment from 2012 to 2020 from the Web of Science Core Collection (WoSCC), screening them according to the inclusion criteria. A total of 965 related papers were included, and the total number of publications increased year by year. We used CiteSpace 5.7. R2, VOSviewer and Microsoft Excel 2019 to evaluate and visualize the results, analyzing institutions, countries/regions, journals, authors, co-cited reference and keywords. Overall, with more and more evidence showing the indispensable role of ferroptosis in cancer, its mechanism research and target discovery may become the main direction of future research.

The gut microbiota has an important role in the pathogenesis of hepatic encephalopathy(HE). Rifaximin, an intestinal non-absorbable antibacterial agent, is effective in the treatment of HE. However, whether long-term prophylactic use induces antibacterial resistance and its mechanism for treating HE remains unclear. This prospective study assessed the impact of 12 weeks rifaximin administration on the gut microbiota and resistome in cirrhotic patients. Fecal sampling was conducted 1 day before the first rifaximin administration and at Weeks 1, 2, 4, 6, 8, 10, 12 of the study. Thirty cirrhotic patients who were in remission from recurrent HE was enrolled to receive rifaximin (400mg TID for 12 weeks). Rifaximin improved hyperammonemia and cognitive function in the 21 patients who completed rifaximin treatment. The dynamic observations showed the gut microbiota diversity, composition and the number of resistance genes, plasmids, insertion sequences did not change significantly during the period(P>0.05). Metabolic pathways such as aromatic amino acids, tryptophan synthesis, urea cycle, and LPS synthesis reduced. No new antimicrobial resistance genes was emergenced. However, the number of aminoglycosides, rifamycin and phenolic resistance genes increased, whereas tetracycline, fosfomycin and cephamycin decreased (P<0.05). Changes in the abundance of E. coli, K. pneumoniae, and B. longum strains correlated with changes of resistance genes. Prophylactic use of rifaximin for 12 weeks improved hyperammonemia and neurophysiological function, maintained gut microbiota diversity, composition and did not change the overall resistome. Rifaximin altered expression of HE-related metabolic pathways. All of these effects could play a key role in preventing HE.
