El metabolismo representa el nivel biológico que más se relaciona con los fenotipos de la célula y, las alteraciones o reprogramaciones de éste pueden, entre otras, (i) afectar la producción de metabolitos primarios o secundarios en microorganismos de interés biotecnológico, (ii) favorecer o no la inhibición del crecimiento en organismos patógenos y (iii) desarrollar desórdenes metabólicos como la obesidad o la diabetes. Es por ello, que el estudio del metabolismo, el rediseño, y el redireccionamiento de fluxes metabólicos se ha convertido en un área importante de investigación (también conocida como Ingeniería Metabólica), ya que ha permitido el desarrollo y diseño de procesos biológicos mejorados, la identificación de blancos terapéuticos, el diseño de estrategias terapéuticas para curar desordenes metabólicos y la identificación de biomarcadores en cáncer, entre otros. Actualmente, se han desarrollado metodologías computacionales que permiten estudiar el metabolismo celular a diferentes condiciones medioambientales, dirigiendo la experimentación con las predicciones del modelo. El propósito de esta revisión es resaltar la importancia del análisis de fluxes metabólicos como una metodología general para estudiar la reprogramación metabólica en distintos organismos de interés biotecnológico, médico, y terapéutico. Este trabajo condensa las bases teóricas y los conceptos claves para entender el análisis de fluxes metabólicos, lo cual será un insumo fundamental para aquellos que se están adentrando al mundo de la biología de sistemas o áreas afines.
Behavior of horizontal sub-surface flow wetlands as an alternative for the wastewater treatment contaminated with florfenicol
Authors: Rodriguez Diana Catalina , Cardona Mary A , Peñuela Gustavo
Published: November 2020

In recent years, the increase in the use and production of antibiotics for the protection of animals has been associated not only with human health problems due to bacterial resistance, but also with environmental problems, which have led to the deterioration of the water resources, since a large part of these are discharged into the environment without any type of treatment. This situation has highlighted the fact that a large part of the antibiotics are not efficiently removed in conventional wastewater treatment plants, being necessary to implement efficient and low-cost treatment alternatives. The evaluation of the removal of the antibiotic florfenicol was carried out using pilot horizontal subsurface flow wetlands, with a hydraulic retention time of 4.2 d, planted with macrophytes (Phragmites australis) and using concentrations of 10, 15, 20 and 25 mg/L of florfenicol. It was concluded that the removal of the antibiotic and the COD was decreasing over time, with a maximum removal percentage of 77.9% of florfenicol and 85.2% of COD during the first days of exposure. The results found allowed to demonstrate that florfenicol was not retained in the granular material of the wetlands, even in the macrophytes and that the predominant removal mechanism was biological degradation.

Informal Professional Development on Twitter: Exploring the Online Communities of Mathematics Educators
Authors: Ruddock Jaymie
Published: November 2020

Professional development in its most traditional form is a classroom setting with a lecturer and an overwhelming amount of information. It is no surprise, then, that informal professional development away from institutions and on the teacher's own terms is a growing phenomenon due to an increased presence of educators on social media. These communities of educators use hashtags to broadcast to each other, with general hashtags such as #edchat having the broadest audience. However, many math educators use the hashtags #ITeachMath and #MTBoS, communities I was interested in learning more about. I built a Python script that used Tweepy to connect to Twitter's API, using try/except blocks to catch HTTP status codes that Twitter occasionally passes through the API. When it was finally completed, a sample of such tweets was collected and then processed using Python to determine polarity, objectivity, and word frequency, first as a group and then by choice of hashtag. Additional analysis included Latent Dirichlet Allocation and hierarchical clustering, and conversations between individuals were analyzed for topic and complexity to understand the extent of interactions. This information will be used to determine the extent of professional development (PD) that teachers do on Twitter simply by actively participating in such communities and ways to improve informal PD. It was determined that there is a significant amount of professional development opportunities on Twitter, but they are muddled by a lot of other content. Further research into the types and the frequency of collaborations on top of the existing latent topics could provide insight into the applications of informal professional development.

National Education Policy 2020: What is in it for a student, a parent, a teacher, or us, as a Higher Education Institution/University?
Authors: Panditrao Mridul Madhav , Panditrao Minnu Mridul
Published: November 2020

Ministry of Human Resource Development of Government of India has projected an elaborate and all-encompassing National Education Policy 2020 (NEP2020). Before independence, the education in India was under the complete control of the “Masters, the British Empire.” The education policies, like the one drawn by Macaulay, as would be obvious, were not for providing any quality education to the Indians, but to churn out the “Babus;” clerks and bureaucrats, to serve the masters, pure and simple. After independence, the society went through series of changes, policies were charted and certain reforms were brought in, but the impact was still not achieved. In 2015, the GOI adapted, “2030 Agenda for Sustainable Development (SD)” and since then the impetus has been initiated. The final culmination of a long drawn and all-inclusive process is NEP2020. NEP2020 has been a very elaborate planning document. The salient features of the issues, principles, aims, vision, challenges and solutions have been dealt with in this article. The main focus has been on the higher education and its implementation. Due importance also has been accorded to other issues such as vocational education, research and online and digital education to mention a few. Overall, it is a commendable and a very positive step forward on the part of the government. Only the time will judge, how much net effective output is actually garnered.
Extradural minipterional approach for giant intracranial aneurysms
Authors: Martinez-Perez Rafael , Tsimpas Asterios , Joswig Holger , Hernandez-Alvarez Victor , Mura Jorge
Published: November 2020

Background:

The clinical applicability of the minipterional (MPT) craniotomy is still limited to small and superficial anterior circulation aneurysms. We discuss the technical nuances of a modified MPT approach, the extradural MPT approach (eMPTa), for the treatment of a giant intracranial aneurysm (GIA) arising from the paraclinoid carotid artery.

Case Description:

A 44-year-old female presented with facial hypoesthesia and third cranial nerve palsy. Further investigations revealed the presence of a 27 mm aneurysm arising from the communicating segment of the internal carotid artery. The patient underwent surgical clipping through an extradural MPT craniotomy and combined anterior clinoidectomy. Postoperative angio-computed tomography demonstrated complete aneurysm occlusion and patency of the parent vessels. The patient recovered fully from her previous deficits.

Conclusion:

The skull base drilling, interdural dissection, and anterior clinoidectomy are key steps during the eMPTa that optimizes the use of the extradural corridor. Such adaptations are enough to improve the surgical maneuverability along the paraclinoid region and adapt the MPT suitability for the treatment of complex GIA.

Published: November 2020

Background:

Standard of care for glioblastoma (GB), consisting of cytotoxic chemotherapy, steroids, and high-dose radiation, induces changes in the tumor microenvironment through its effects on glucose availability, which is a determinant for tumor progression (TP). Low-carbohydrate diet (LCD) reduces the glucose levels needed to drive the Warburg effect.

Methods:

To investigate LCD’s effect on GB therapy, we have begun a clinical trial using LCD as an addition to intranasal perillyl alcohol (POH) for recurrent GB (rGB) patients. This study involved 29 individuals and evaluated, over a period of 1 year, the adjuvant effect of LCD associated with POH therapy in terms of toxicity, extent of peritumoral edema, reduced corticosteroid use, seizure frequency, and overall survival. POH group (n = 14) received solely intranasal POH without specific diet regimen, whereas POH/LCD group (n = 15) received intranasal POH in combination with nutritional intervention. Patients’ assessment was based on clinical reviews and magnetic resonance data.

Results:

In the 1-year follow-up, the POH/LCD group showed a 4.4-fold decrease in the proportion of patients who needed treatment with corticosteroids, as well as a reduction in tumor size and peritumoral edema, as compared to the POH group. While 75% of patients undergoing POH treatment experienced seizures, this fraction was reduced to 56% in the POH/LCD group. A 2.07-fold increase in the proportion of patients with stable disease, along with a 2.8-fold decrease in the proportion of patients with TP, was seen in the POH/LCD group.

Conclusion:

The results presented in this study show that the LCD associated with intranasal POH therapy may represent a viable option as adjunctive therapy for rGB to improve survival without compromising patients’ quality of life. Prospective cohort studies are needed to confirm these findings and validate the efficacy of this novel therapeutic strategy.

Published: November 2020

Background:

Decompressive craniectomy (DC) is the preferred surgical management option for lowering refractory intracranial pressure in cases of traumatic brain injury (TBI). A number of randomized controlled trials have demonstrated decreased mortality but increased morbidity following DC for TBI patients. Here, we reviewed the frequency of postoperative hemorrhagic complications following DC correlating with poor outcomes.

Methods:

We retrospectively reviewed the medical records of patients who presented with TBI and underwent DC during the years 2015–2017. The frequency and characteristics of hemorrhagic complications were correlated with the patients’ outcomes.

Results:

There were 74 patients with TBI included in the study who underwent DC. Of these, 31 patients developed expansion of existing hemorrhagic lesions, 13 had new contusions, three developed new extradural hemorrhages, two developed new subdural hematomas, and one patient developed an intraventricular hemorrhage. Those who developed expansion of existing hemorrhagic lesions following DC had longer ICU stays and poorer outcomes (Glasgow outcome scale).

Conclusion:

After 74 DC performed in TBI patients, 67% developed new hemorrhagic lesions or expansion of previously existing hemorrhages. This finding negatively impacted clinical outcomes, including mortality.

A story of levels
Authors: Kuehne Thomas
Published: November 2020

© 2018 CEUR-WS. All rights reserved. Despite being one of the fundamental concepts of multi-level modeling - to the extent of occurring in the name of the discipline - the concept of “level” has no universally agreed upon meaning among multi-level modeling researchers. There is no consensus on what the nature of a level is nor on how levels should be used to organize modeling elements. In this paper, I aim to initiate a discussion on what the options for defining levels in multi-level modeling are and how they could be systematically characterized.
In defence of deep modelling
Authors: Atkinson C , Kuehne Thomas
Published: November 2020

© 2015 Elsevier B.V. Since multi-level modelling emerged as a strategy for leveraging classification levels in conceptual models, there have been discussions about what it entails and how best to support it. Recently, some authors have claimed that the deep modelling approach to multi-level modelling entails paradoxes and significant weaknesses. By drawing upon concepts from speech act theory and foundational ontologies these authors argue that hitherto accepted principles for deep modelling should be abandoned and an alternative approach be adopted instead (Eriksson et al., 2013). Objective We investigate the validity of these claims and motivate the need to shift the focus of the debate from philosophical arguments to modelling pragmatics. Method We present each of the main objections raised against deep modelling in turn, classify them according to the kinds of arguments put forward, and analyse the cogency of the supporting justification. We furthermore analyse the counter proposal regarding its pragmatic value for modellers. Results Most of the criticisms against deep modelling are based on mismatches between the premisses used in published definitions of deep modelling and those used by the authors as the basis of their challenges. Hence, most of the criticisms levelled at deep modelling do not actually apply to deep modelling as defined in the literature. We also explain how the proposed alternative introduces new problems of its own, and evaluate its merits from a pragmatic modelling perspective. Finally, we show how deep modelling is indeed compatible with, and can be founded on, classic work in linguistics and logic. Conclusions The inappropriate interpretations of the core principles of deep modelling identified in this article indicate that previous descriptions of them have not had sufficient clarity. We therefore provide further clarification and foundational background material to reduce the chance for future misunderstandings and help establish deep modelling as a solid foundation for multi-level modelling.

One of the main factors affecting the efficiency of agricultural production, timing and quality of agricultural work is the availability of equipment. Among all the variety of agricultural machines, tractors are of key importance. The measures taken by the state to support technical modernization contribute to the partial renewal of the tractor fleet of agricultural organizations, but do not allow to stop the process of its reduction. The existing volumes of purchasing tractors are not enough to radically change the situation. The fleet of agricultural tractors continues to decrease and along with it, the indicators of tractor availability are decreasing, which negatively affects the quality and timing of agricultural work. In terms of availability of agricultural tractors, Russia lags far behind the majority of both developed and developing countries in the world. The growing load on tractors and their high average age lead to violations of agricultural deadlines, increased downtime of equipment, additional material and technical costs for repairs, increased consumption of fuel and lubricants, seeds, fertilizers, etc. In the domestic tractor industry, a difficult situation also remains. The existing nomenclature and production volumes of domestic tractor-building enterprises do not allow to meet the needs of agriculture. There is practically no production of crawler tractors, specialized tractors for gardening and viticulture. In this regard, there is a high dependence on the supply of imported tractors. Despite the significant decline in machinery output in recent years, the Republic of Belarus remains a leader in the production and import of agricultural tractors to Russia and the CIS countries.
The degree of dominance and heterosic effect in tomato hybrids on the main economic features

In Dagestan, like many southern subjects of the country, the environment of vegetable crops tomato is the most common crop. The basis for getting high tomato yields are heterosic hybrids. The research work was carried out during 2018-2019. on the experimental field of the Federal Agricultural Research Center of the Republic of Dagestan. The object of the study in 2018 were hybrids of tomato of the first generation of recyproccal interbreeding. In 2019, direct and reverse artificial crossings involved 11 pairs of initial forms of early-ripe and medium-ripened groups with higher productivity. Reciprocal hybrids with the participation of the variety Local in pair L 23/12, L 17/03, 23/04 and Spartacus on the grounds of "the number of fruit branches and the number of fruits" was high and, although the parents had the same indicators on these grounds (the number of fruit-bearing branches in the variety Local - 4.2 pieces, L 23/12 - 4.2 pieces, L 23/04 - 4.4 pieces and Spartacus - 4.0). In reverse combinations, heterosis was manifested, but the effect was lower compared to the indicators in direct combinations. The reciprocal hybrids of the pair of Varieties Spartacus and Local had a high heterosic effect in the reverse combination, when The Local acted as a maternal form (the degree of heterosis by the number of fruit-bearing branches 121% instead of 17% and the number of fruits on the first brush 124% instead of 22% in the direct combination of Spartacus x Local).Four reciprocal hybrid combinations with positive overdominance have been revealed. The degree of dominance in the "number of fruits on the first brush" ranged from - 0.4 to 104. The results of the study of the dominance and heterosis effect of the "number of fruits on the plant" indicate the high sectional value of the reciprocal hybrids studied.

The article presents the results of a test of new varietal species of baby eagles in a breeding nursery in 2018 - 2019. The options for the first and second year of use were evaluated. The purpose of these studies was to identify the most valuable economic traits of new highly productive varieties for use in further work. Weather and climatic conditions were generally favorable for the wintering and development of plants of horned calves in the spring and summer. During field trials, it was found that in terms of green mass yields in the total over two years of use, the E-25 variant stood out (+ 30.5% to Smolensky 1 standard). Over the entire period of testing, he showed a high and stable increase. It was slightly lower with the E-49 varietomer (+ 24.2%), which showed higher yields in the first year of use than in the second. They also stood out by the yield of air-dry matter (+ 21.4% and + 31.45%, respectively). Such productivity of the plant of horned lamb was shown in the conditions of sowing on slightly acidic loamy soil with a low content of humus, mobile potassium and a high content of phosphorus.

The analysis of the agricultural production in the Volgograd region supplying agricultural products in the monetary equivalent of 128 billion rubles per year which plays a significant role in the implementation of the Food Security Program in Russia is carried out. The yield and gross yield of crops can be significantly increased as the result of the energy growth in the soil. Soil energy efficiency coefficient which includes natural energy indicators; the energy contained in the humus and mineral substance as well as anthropogenic energy being received as the result of organic and mineral substances application to assess the energy status in the modern conditions and to meet the needs for agro-reclamation and hydro-reclamation is proposed. Simulation calculations having carried out with the help of computer the model showed that development of irrigation was required to increase the biological productivity of the soil, along with fertility increase.
