Published: June 2021

Objetivou-se por meio do estudo avaliar o comportamento de coleta de abelhas africanizadas em flores de árvores de Nim no município de Picos, Piauí, Brasil. Para tanto, no período de fevereiro a dezembro de 2016, durante três dias consecutivos de cada mês, foi realizada uma avaliação da atividade de coleta das abelhas em 10 árvores de Nim em florescimento. Essa avaliação foi realizada anotando-se das 7 às 13h, a cada 2 horas, durante 5 minutos, em cada árvore: i. o número de abelhas africanizadas visitantes, ii. o (os) recurso(s) coletado(s), iii. a presença de outros visitantes e iv. os aspectos da biologia floral (antese, receptividade do estigma e odor). Como resultados, constatou-se que as árvores de Nim, nas condições climáticas do município de Picos, florescem e frutificam o ano todo. Essa árvore apresenta artifícios para atrair seus visitantes florais, como a liberação de odor intenso e a disponibilidade de pólen abundante durante o período de observação. Durante o período chuvoso na região, o número de abelhas visitantes (36) foi muito inferior ao período seco (282). Esses insetos permaneceram visitando as flores de Nim durante o período avaliado, com pico de visitação logo no primeiro horário de observação (7 às 8h), sendo o pólen o principal recurso coletado. Concluiu-se que as abelhas africanizadas visitam as flores de Nim para a coleta de recursos florais (pólen), que podem compor a dieta das colônias principalmente durante o período de escassez de flores no campo.

Published: June 2021

El contrato atípico de servicios logísticos contiene prestaciones complejas diseñadas según el tráfico comercial. Empero, cuando surgen conflictos interpretativos los jueces recurren a criterios externos a la ecuación económica inicial. Esto puede llevar a consecuencias indeseadas. La presente investigación indaga por los límites de la filosofía kantiana para solucionar el problema. Se concluye que la igualdad puede ser un fundamento no utilitarista para la interpretación, pero sigue recurriendo a algo más que la voluntad. Al final, se propone el concepto de persona razonable, pues respeta la lógica comercial del negocio y al mismo tiempo es un método hermenéutico que resulta eficaz.

Published: June 2021

The expression of eukaryotic genes can be regulated at several stages, including the translation of mRNA. It is known that the structure of mRNA can affect both the efficiency of interaction with the translation apparatus in general and the choice of translation initiation sites. To study the translated fraction of the transcriptome, experimental methods of analysis were developed, the most informative of which is ribosomal profiling (RP, Ribo-seq). Originally developed for use in yeast systems, this method has been adapted for research in translation mechanisms in many plant species. This technology includes the isolation of the polysomal fraction and high-performance sequencing of a pool of mRNA fragments associated with ribosomes. Comparing the results of transcript coverage with reads obtained using the ribosome profiling with the transcriptional efficiency of genes allows the translation efficiency to be evaluated for each transcript. The exact positions of ribosomes determined on mRNA sequences allow determining the translation of open reading frames and switching between the translation of several reading frames – a phenomenon in which two or more overlapping frames are read from one mRNA and different proteins are synthesized. The advantage of this method is that it provides quantitative estimates of ribosome coverage of mRNA and can detect relatively rare translation events. Using this technology, it was possible to identify and classify plant genes by the type of regulation of their expression at the transcription, translation, or both levels. Features of the mRNA structure that affect translation levels have been revealed: the formation of G2 quadruplexes and the presence of specific motifs in the 5’-UTR region, GC content, the presence of alternative translation starts, and the influence of uORFs on the translation of downstream mORFs. In this review, we briefly reviewed the RP methodology and the prospects for its application to study the structural and functional organization and regulation of plant gene expression.
Intraspecific diversity of durum wheat (Triticum durum Desf.): a unif ied classif ication
Authors: Lyapunova О. A.
Published: June 2021

The Department of Wheat Genetic Resources of the All-Russian Research Institute of Plant Genetic Resources (VIR) had developed and published in 1979 a classification of the genus Triticum L., which is based on the genomic composition of species and the presence or absence of a number of main genes that govern the “classification” traits. The grounds have been laid by F. Körnicke and J. Percival, and supplemented by N.I. Vavilov and K.A. Flaksberger. The classification, which is most often referred to as the “Classification of Triticum by Dorofeev et al.”, belongs to a number of the main modern classifications of the genus. This is the world’s first standardized system that contains all known intraspecific (infraspecific) taxa of wild and cultivated wheat species. A detailed classification makes it possible to identify a wide variety of forms in the genus Triticum L. and its individual species, which is especially important for collections preserved in genetic seed banks. The use of the intraspecific classification of the genus Triticum L. greatly simplifies the identification of the VIR collection accessions introduced from various sources or checking accession identity after regeneration in the field. However, the direct use of such a voluminous classification meets several difficulties. Therefore, we propose a unified intraspecific classification of durum wheat, based on the description of only 16 main botanical varieties out of 131 described so far, which have complexes of morphological traits of the spike and kernel that occur most frequently in durum wheat collections. The remaining 115 botanical varieties, which have additional traits, get their name by the addition of the abbreviated Latin name of one or another additional trait to the main name. Having mastered this way of describing the morphological traits of accessions, any user can easily navigate oneself in the systematized intraspecific diversity of collections. The purpose of this work is to acquaint the reader with the intraspecific classification of durum wheat (Triticum durum Desf.) developed at VIR and to offer its simplified version, which is based on the identification of the main and additional morphological traits of the spike and kernel.
Potato spindle tuber viroid

Published: June 2021

Viroids belong to a very interesting class of molecules attracting researchers in phytopathology and molecular evolution. Here we review recent literature data concerning the genetics of Potato spindle tuber viroid (PSTVd) and the mechanisms related to its pathological effect on the host plants. PSTVd can be transmitted vertically through microspores and macrospores, but not with pollen from another infected plant. The 359 nucleotidelong genomic RNA of PSTVd is highly structured and its 3D-conformation is responsible for interaction with host cellular factors to mediate replication, transport between tissues during systemic infection and the severity of pathological symptoms. RNA replication is prone to errors and infected plants contain a population of mutated forms of the PSTVd genome. Interestingly, at 7 DAI, only 25 % of the newly synthesized RNAs were identical to the master copy, but this proportion increased to up to 70 % at 14 DAI and remained the same afterwards. PSTVd infection induces the immune response in host plants. There are PSTVd strains with a severe, a moderate or a mild pathological effect. Interestingly, viroid replication itself does not necessarily induce strong morphological or physiological symptoms. In the case of PSTVd, disease symptoms may occur due to RNA-interference, which decreases the expression levels of some important cellular regulatory factors, such as, for example, potato StTCP23 from the gibberellic acid pathway with a role in tuber morphogenesis or tomato FRIGIDA-like protein 3 with an early flowering phenotype. This association between the small segments of viroid genomic RNAs complementary to the untranslated regions of cellular mRNAs and disease symptoms provides a way for new resistant cultivars to be developed by genetic editing. To conclude, viroids provide a unique model to reveal the fundamental features of living systems, which appeared early in evolution and still remain undiscovered.
Problems of mini-pig breeding
Authors: Shatokhin K. S.
Published: June 2021

This article provides an overview of some problems of the breeding and reproduction of laboratory minipigs. The most obvious of these are the lack of centralized accounting of breeding groups, uniform selection standards for reproduction and evaluation of breeding animals, as well as minimizing the accumulation of fitness-reducing mutations and maintaining genetic diversity. According to the latest estimates, there are at least 30 breeding groups of mini-pigs systematically used as laboratory animals in the world. Among them, there are both breed formations represented by several colonies, and breeding groups consisting of a single herd. It was shown that the main selection strategy is selection for the live weight of adults of 50–80 kg and the adaptation of animals to a specific type of biomedical experiments. For its implementation in the breeding of foreign mini-pigs, selection by live weight is practiced at 140- and 154-day-old age. It was indicated that different herds of mini-pigs have their own breeding methods to counteract inbred depression and maintain genetic diversity. Examples are the maximization of coat color phenotypes, the cyclical system of matching parent pairs, and the structuring of herds into subpopulations. In addition, in the breeding of foreign mini-pigs, molecular genetic methods are used to monitor heterozygosity. Every effort is made to keep the number of inbred crosses in the breeding of laboratory mini-pigs to a minimum, which is not always possible due to their small number. It is estimated that to avoid close inbreeding, the number of breeding groups should be at least 28 individuals, including boars of at least 4 genealogical lines and at least 4 families of sows. The accumulation of genetic cargo in herds of mini-pigs takes place, but the harmful effect is rather the result of erroneous decisions of breeders. Despite the fact that when breeding a number of mini-pigs, the goal was to complete the herds with exclusively white animals, in most breeding groups there is a polymorphism in the phenotype of the coat color.
Lack of GAGA protein in Trl mutants causes massive cell death in Drosophila spermatogenesis and oogenesis

Published: June 2021

Drosophila protein GAGA (GAF) is a factor of epigenetic transcription regulation of a large group of genes with a wide variety of cellular functions. GAF is encoded by the Trithorax-like (Trl) gene, which is important for the formation of various organs and tissues at all stages of ontogenesis. In our previous works, we showed that this protein is necessary for the development of the reproductive system, both in males and females of Drosophila. Decreased expression of the Trl gene led to multiple disorders of spermatogenesis and oogenesis. One of the significant disorders was associated with massive degradation and loss of cells in the germline. In this work, we carried out a more detailed cytological study to determine what type of germ cell death is characteristic of Trl mutants, and whether there are disturbances or changes in this process compared to the norm. The results obtained showed that the lack of GAF protein causes massive germ cell death in both females and males of Drosophila, but this death manifests itself in different ways, depending on the sex. In Trl females, this process does not differ phenotypically from the norm. In the dying egg chambers, signs of apoptosis and autophagy were revealed, as well as morphological features that are characteristic of the wild type. In males, Trl mutations induce mass germ cell death through autophagy, which is not typical of Drosophila spermatogenesis, and has not been previously described, neither in the norm nor in other genes’ mutations. Thus, GAF lack in Trl mutants leads to increased germ cell death through apoptosis and autophagy. Ectopic cell death and germ line atrophy are probably associated with impaired expression of the GAGA factor target genes, among which there are genes that regulate both apoptosis and autophagy.
The finding and researching algorithm for potentially oscillating enzymatic systems

Published: June 2021

Many processes in living organisms are subject to periodic oscillations at different hierarchical levels of their organization: from molecular-genetic to population and ecological. Oscillatory processes are responsible for cell cycles in both prokaryotes and eukaryotes, for circadian rhythms, for synchronous coupling of respiration with cardiac contractions, etc. Fluctuations in the numbers of organisms in natural populations can be caused by the populations’ own properties, their age structure, and ecological relationships with other species. Along with experimental approaches, mathematical and computer modeling is widely used to study oscillating biological systems. This paper presents classical mathematical models that describe oscillatory behavior in biological systems. Methods for the search for oscillatory molecular-genetic systems are presented by the example of their special case – oscillatory enzymatic systems. Factors influencing the cyclic dynamics in living systems, typical not only of the molecular-genetic level, but of higher levels of organization as well, are considered. Application of different ways to describe gene networks for modeling oscillatory molecular-genetic systems is considered, where the most important factor for the emergence of cyclic behavior is the presence of feedback. Techniques for finding potentially oscillatory enzymatic systems are presented. Using the method described in the article, we present and analyze, in a step-by-step manner, first the structural models (graphs) of gene networks and then the reconstruction of the mathematical models and computational experiments with them. Structural models are ideally suited for the tasks of an automatic search for potential oscillating contours (linked subgraphs), whose structure can correspond to the mathematical model of the molecular-genetic system that demonstrates oscillatory behavior in dynamics. At the same time, it is the numerical study of mathematical models for the selected contours that makes it possible to confirm the presence of stable limit cycles in them. As an example of application of the technology, a network of 300 metabolic reactions of the bacterium Escherichia coli was analyzed using mathematical and computer modeling tools. In particular, oscillatory behavior was shown for a loop whose reactions are part of the tryptophan biosynthesis pathway.

Transnasal Endoscopic Resection of a Huge Solitary Fibrous Tumor Originated From Frontal Recess
Authors: Ryu Somi , Lee Sang Yun , Kim Sang-Wook , Cho Hyun-Jin
Published: June 2021

Solitary fibrous tumor (SFT) is a spindle cell neoplasm that occurs commonly in the pleural space. One-third of SFTs arising from an extrathoracic organ are found in the head and neck region, and they arise rarely in the sinonasal tract. Most of these tumors are benign, but malignant tumors are identified in some cases. Here we report a rare sinonasal SFT arising from the frontal recess. A 32-year-old male patient with chief complaint of headache and left facial pain visited the outpatient clinic. He had suffered from paranasal pain and nasal obstruction for several months, and symptoms became more severe in the previous three months. The mass rapidly increased in size and was protruding from the left nostril when he visited the hospital. After computed tomography and magnetic resonance imaging scans, transnasal endoscopic resection of the tumor was performed, and gross total tumor removal was successfully achieved. We believe this case will be helpful for providing information regarding management of such uncommon huge sinonasal tumors originating from the frontal recess.
An overview of employment generation in the sectors of GHANA’S economy: Foreign direct investment perspective
Authors: Yeboah Evans , Kyeremeh Rose Gyamea
Published: June 2021

As foreign direct investment (FDI) contributes to economic growth and development of the host country, it also serves as a basis of employment creation in an economy. Over the past years, FDI has helped accumulate capital for developmental projects in most developing and least developed countries. This study provides an overview of job creation through FDI inflow within the Ghanaian economy by considering the number of jobs allocated to the various sectors. The study makes use of a descriptive statistical method that quantitatively supports data analysis. The results show that as the total FDI registered projects decrease, the number of expected jobs to be created also declines. The outcome also revealed that the service sector enjoys a higher percentage of the FDI registered project and the total number of employments generated within the selected period. The result further indicates that about 84% of the aggregate jobs created were for Ghanaians. The outcome also showed that the tourism and export trade sectors’ performance towards job generation from FDI inflow is lower than other sectors of the economy. It is suggested that the government should continue to put in a great effort to make the country’s business environment much friendly for investors.

Published: June 2021

Objective: In the COVID-19 pandemic, it is necessary and crucial for local authorities to be aware of the prospective behavior and perception of individuals so that health authorities can effectively respond and be prepared for the pandemic. This study has focused on researching people's attitudes and behaviors towards COVID-19 within the context of theory of planned behavior (TPB). Methods: In the study, initially, a research model was designed within the scope of TPB, and then in order to analyze the relationships in the model, a data collection tool was developed. Ultimately, the fit of the proposed modeling and the test of hypotheses were conducted through using partial least squares structural equation modeling (PLS-SEM). Results: As a result of the research, it was found out that as the anxiety about COVID-19 soared the intention to go out was decreased, while the behavior of taking precautions increased. Also, it was indicated that as the intention of going out was decreased by one point, the behavior of taking measures against the transmission of COVID-19 increased by 0.28 points. Conclusions: In the study, it could be stated that the model proposed within the scope of TPB fits well with the perceived attitudes and behaviors towards COVID-19. It was determined that as the anxiety towards COVID-19 increased, the intention of going out was decreased and the behavior of taking measures increased.

Authors: Wijayanti Pipit , Noviani Rita
Published: June 2021

This study aims to determine the potential of Duwet springs and their availability for supplying fresh water to the surrounding community. we use hydrographs to analyze aquifer characteristics. To analyze the hydrographs, we use water level and spring discharge data. Automatic Water Level Record (AWLR) records water level data for 1 dry season and 1 rainy season every 15 minutes. We use the volumetric method to measure the spring discharge 14 times. We compare the base flow and demand over a year to analyze the potential for fresh water. The results show that the Stage discharge rating curve y = 0.0002e5,453x with R² value of 0.87. Duwet Springs is a perennial spring that has a small discharge (class VI). The largest discharge ever recorded was 0.69 L/s (March 7, 2020) and the smallest recorded was 0.12 L/s (August 21, 2020). BFI value varied between 0.05 and 1 with mean 0.801. The total base flow is 2490675.734 L (rainy season) and 1563419.873 L (dry season). These springs are sufficient for 75% of the rainy season and 84% in the dry season. This indicates that the existence of Duwet springs is very important for the surrounding community.

While carrying out its essential duties to provide adequate foods for people, the agriculture sector is facing sustainability issues. The study presents a case study of West Nusa Tenggara (NTB), whereby an increase of urban expansion activities has begun to create a centrifugal force to the province that is popularly called as the granary of Indonesia. Urban settlements slowly leapfrogged to the outskirts and reduced the size of prime agricultural lands. Moreover, existing planning policies were unable to control the situation and many farmers leave their jobs because the setback of farmers wellbeing. The size of agricultural land is highly influential towards farmer motivation to stay engaged in the farming sector. Applying qualitative methods, this study examined the minimum area of agriculture land (focusing on paddy field) to promote farmer’s well-being following three steps of the analytical framework: total agricultural production estimation, the average well-being estimation, and the prediction of minimum land provision for the average well-being. After all, one of the key important findings reveals that the average of minimum agricultural land to ensure famers wellbeing for the whole NTB Province is 0.74 Ha.
