Protocol for evaluating the abilities of diverse nitroaromatic prodrug metabolites to exit a model Gram negative bacterial vector
Authors: Chan-Hyams JVE , Ackerley David
Published: June 2020

© 2020 The Authors Bacterial-directed enzyme-prodrug therapy (BDEPT) uses tumour-tropic bacteria armed with a genetically-encoded prodrug-converting enzyme to sensitise tumours to a systemically-administered prodrug. A strong bystander effect (i.e., efficient bacteria-to-tumour transfer of activated prodrug metabolites) is critical to maximise tumour cell killing and avoid bacterial self-sterilisation. To investigate the bystander effect in bacteria we developed a sensitive screen that utilised two Escherichia coli strains grown in co-culture. The first of these was an activator strain that overexpressed the E. coli nitroreductase NfsA, and the second was a nitroreductase null recipient strain bearing an SOS-GFP DNA damage responsive gene construct. In this system, induction of GFP by genotoxic prodrug metabolites can only occur following their transfer from the activator to the recipient cells. This can be monitored both in fluorescence based microtitre plate assays and by flow-cytometry, enabling modelling of the abilities of diverse nitroaromatic prodrug metabolites to exit a Gram negative vector.

Authors: Al Tannir Mohamad , Abu Shaheen Amani , Altannir Youssef , Altannir Mustafa
Published: June 2020

Background: Saudi Arabia doubled its tobacco tax in June 2017. Aims: To examine the association between an increase in tobacco prices and consumption behaviour among current male smokers in Riyadh. Methods: We conducted a community-based study using a self-administered questionnaire distributed to current male smokers aged 15+ years in Riyadh in 2018. The survey included questions on sociodemographic characteristics, tobacco consumption and self-reported chronic health conditions. Results: A total of 1481 participants were included in the final data analysis. After the tobacco tax was doubled, 25.6% of the participants reduced their cigarette consumption and 1.0% quit smoking. The average daily cigarette consumption after enforcing the tobacco tax [19.77, standard deviation (SD) 10.7], was statistically significantly lower than before taxation (21.19, SD 10.8) (P < 0.0001). The calculated price elasticity of demand was −0.20 (inelastic). Employment status (P = 0.002) and per capita gross domestic product purchasing power parity (P = 0.001) were the only statistically significant factors associated with the change in smoking habits. Conclusions: Increasing tobacco prices reduced tobacco consumption by 26.6% among Saudi Arabian male smokers
Psychometric Analysis of a Proposed Model to Determine Factors Influencing Selection of a Research Supervisor
Authors: Shafiq Ali , Pahlevan Sharif Saeed , Jan Anbareen
Published: June 2020

Aim/Purpose: This paper found some factors which influence research supervisees’ selection of their research supervisors.

Background: Research on supervisor-supervisee relationship is mostly conducted when research students have already initiated their studies. Research on how a supervisor is selected before the research begins is researched less. How do supervisees select their supervisors? Which factors do they consider important? These questions were not clearly answered in the literature so far.

Methodology: A scale was developed to measure factors which influence the selection of research supervisors. Using an online survey, data was collected from 315 research students in Malaysia between August and October 2018. Psychometric properties of the scale were assessed using exploratory factor analysis followed by confirmatory factor analysis. Construct reliability, convergent validity, and discriminant validity of the scale were assessed using composite reliability, maximal reliability, average variance extracted, and maximum shared variance.

Contribution: How research supervisees select their supervisors is an understudied area. Most of the research on supervisor selection is done after the research journey has begun. This research focuses on the thought processes before supervisor selection.

Findings: Demographics, expertise, and physical appearance emerge as important constructs that influence the thought process of a research supervisee. Each of these constructs is composed of several dimensions, each with its own weight and importance.

Recommendations for Practitioners: Research supervision is an integral part of contemporary teaching profession. To develop this important dimension of an academic’s career, this research holds high significance. The emerging factors will help researcher supervisors enhance their profiles and become more visible. This has practical implications for higher education institutions as well.

Recommendation for Researchers: Further studies in this area can explore these factors across different cultures, distinction between undergraduate and postgraduate students, public and private higher education institutions, and scholarship or self-funded students.

Impact on Society: Attracting better and relevant research students will result in a better match between researcher’s capability and supervisor’s expertise leading to high impact research.

Future Research: This research was done on only 315 respondents. More respondents from diverse population might influence the outcome.

Published: June 2020

La frontera sur de México presenta grandes desafíos y oportunidades. Es un área de convivencia tradicional y dinámica de frontera diaria. A pesar de no presentar un enemigo tradicional se puede decir; sin embargo, que, a causa de los intereses de los Estados Unidos en la región respecto al control de las actividades del crimen organizado, especialmente las relacionadas con el narcotráfico; así como el tránsito de inmigrantes indocumentados, es que la frontera sur siempre ha formado parte de la agenda de Seguridad Nacional de México. Este documento propone que solo desde un enfoque multidimensional e integral es posible gestionar una frontera que tenga en cuenta a las personas como seres humanos, más allá de su ciudadanía.

Authors: Laznev K. V. , Shumskaya Ye. Y. , Agabekov V. Y.
Published: June 2020

Using emulsification technique, magnetic microspheres (MMS) were prepared from solutions of alginate, pectin, gelatin, chitosan and polyvinyl alcohol. Index of polidispersity of the microspheres was ≤ 0.1. The microspheres from gelatin, chitosan and polyvinyl alcohol covalently crosslinked with glutaraldehyde were resistant to sonication and hydrolysis at room temperature in buffer solution with pH   7.4. The microspheres containing superparamagnetic magnetite particles demonstrated no residual magnetization. After modification, chitosan and polyvinyl alcohol MMS were used for immunomagnetic separation of cells and germs.
Distribution constants and group increments of organic substances in the extraction systems of water saline–hexane
Authors: Mikhniuk O. N. , Leschev S. M. , Kasyanchik P. A.
Published: June 2020

In the extraction systems of hexane–aqueous solutions of potassium carbonate, ammonium sulfate and sodium chloride, the distribution of a number of organic compounds (benzyl alcohol, tetrahydrofuran, phenol, aniline, pyridine, pyridazine, pyrimidine, n-butylamine, diethylamine, triethylamine, benzylamine) was studied. It was shown that sodium chloride, the most frequently used as a salting out agent, is noticeably inferior in salting ability to potassium carbonate, dipotassium phosphate and ammonium sulfate, since it contains singly charged ions with a relatively low charge density. Using the method of group increments on the example of aliphatic alcohols, the salting out ability of a number of mineral salts with singly charged ions was evaluated. By the value of this ability, the salts studied are arranged in the following order: NaNO2 > NaCl > KCl ~ NaBr > NaClO4 > KJ > NH4NO3 > NH4SCN. At the same time, the salting out effect of the last four salts from the above series is small. Based on the usage of the group increment method, the nature of the salting out effect is additionally confirmed, which consists, first of all, in strengthening the structure of the saline solution and increasing the increment of the methylene group (ICH2) with increasing the salt concentration.

Published: June 2020

The excess of magnesium chloride brines is formed during the polymineral ores processing in order to obtain potassium sulfate. One way to regenerate such brines is to produce artificial carnallite. It is necessary to purify these brines from sulfates for their further use as raw materials for the artificial carnallite production. In this work, the process of desulfurization of magnesium chloride brines with a solution of calcium chloride is studied. The temperature and the processing time, the magnesium chloride solutions concentration and the consumption of desulfurizing agent (calcium chloride) influence on the degree of magnesium chloride solutions purification from sulfate ions was determined. It has been established that almost all sulfate ions interact with calcium ion in 15 minutes and the desulfurization degree reaches 98,08 %. The increase in duration of the suspension mixing is necessary in order to establish equilibrium in the system and relieve the supersaturation in the solution. It has been shown that with increasing solutions saturation with MgCl2, the degree of the magnesium chloride brines purification from SO4 2– ion increases. Complete precipitation of calcium sulfate requires a certain excess concentration of calcium chloride.

The article examines the clinical and roentgenological changes in the periodontal tissues of laboratory animals when mesenchymal stem cells (MSC) are used.

The aim of the study is to create a model of experimental periodontitis and identify the characteristics of clinical and radiological changes in periodontal tissues when applying a biomedical cell product based on allogeneic mesenchymal adipose stem cells (AT MSCs).

During the examination of the clinical and radiological changes in the periodontal tissues ofexperimental animals with formed bone defects filled with AT MSCs, it was found that the mucous membrane regeneration time in the surgical area was comparable in all main groups of animals. Postoperative gum recession was observed in the control group animals. The significant differences between the clinical pictures in groups I–IV during all observation periods after surgery were not revealed. However, the restoration process signs in the post-resection area found during the roentgenological examination in the groups using osteoinduced MSCs, as well as a mixture of MSC cultures and osteo-induced MSCs, were most pronounced, which is confirmed by the bone mineral density.

The experimental periodontitis model, which could be used for assessing the bone tissue restoration processes of a labioratory animal, was developed. Thus, the use of collagen membranes with a suspension of allogeneic osteo-induced AT MSCs cultures, as well as membranes with a suspension of a mixture of allogeneic and allogeneic osteo-induced AT MSCs in the ratio of 1:1 allows achieving higher bone tissue recovery rates.

The article is devoted to the analysis of the morphological characteristics of placental tissue in women with early reproductive losses with recurrent miscarriage, depending on the presence of polymorphic variants of metalloproteinases and hemostasis. It was established that in women with recurrent miscarriage, the area of the trophoblast of the placenta is significantly larger (р < 0.003), the area of the chorionic villi is smaller (р < 0.04) than in the group of women with implemented reproductive function. Thrombosis of the chorionic vessels, necrosis and calcinates in the placenta with PNF were detected in 80.0 % (р = 0.001), 93.3 % (р = 0.001), and 30.0 % (р = 0.049) of cases, respectively, which is significantly higher than in the comparison group. In patients with PNP with the T/T genotype of the 735 C/T polymorphism of the MMP-2 gene, the trophoblast area is significant (р < 0.05) more than with the C/C genotype, acute full-back (р = 0.02) and intervillous hemorrhage (р = 0.02). In women with the C/T genotype of the polymorphism 735 C/T of the MMP-2 gene, edema and dystrophic changes in the chorionic villi, placental necrosis are determined more often (р = 0.02) than with the C/C genotype. In carriers of the T allele of the polymorphism 735 C/T of the MMP-2 gene in the placenta, necrosis is significantly more common than in the CC genotype; the carriage of the T allele is also associated with large values of the relative area of the trophoblast and the stromal-intervillous relation, as well as with a smaller value of the ratio of the intervillous space area to the total area of the photograph.

In 7 patients (30.4 %) both knee joints were operated on. TKR of the right knee joint – 16 (53.3 %), left – 14 (46.7 %). With flexion contracture – 6 cases, mixed – 20, rigidity – 4. In 19 cases (63.3 %) deviation of the lower limb axis was >10°.

We used: X-ray, topogram of lower extremities, CT.

For coagulation status assessment we used: screening coagulation test, levels of scarce coagulation factors (FVIII, FIX), inhibitor of coagulation factor (FVIII, FIX) level.

Function was evaluated before and at 1–9 years postoperatively using KSS, Oxford and VAS scales.

Statistical analysis – STATISTICA 6.0, p < 0.05.

An integrated approach to patients’ management by the use of preoperative planning, surgical techniques, selection of an endoprosthesis of the necessary design and a personalized program of hemostasiological support in the perioperative period that we developed allowed us to obtain excellent results in 1-year period after the operation according to the KSS rating scale in 26 (86.7 %) cases, good in 3 (10 %) cases, satisfactory – in 1 (3.3 %). On the Oxford scale, excellent results were obtained in 25 (83.3 %) cases, good in 4 (13.3 %) cases, satisfactory in 1 (3.3 %). 1–9 years after the operation, no statistically significant differences were obtained in the results with data of 1 year (p > 0.05).

The developed tactics of hemostatic replacement therapy and laboratory control provided satisfactory hemostasis in the perioperative period.

Primary immunodeficiency diseases (PID) are a heterogeneous group of genetically determined diseases of the immune system. Patients with a PID are characterized by increased infectious sensitivity, a high rate of development of autoimmune diseases and malignant diseases. All these factors lead to a high incidence of early child mortality.

We identified 191 patients (120 males and 71 female) with genetically confirmed PID, which are represented by 25 nosologies. We found 32 variants that have not been previously described. Most of these variants were small deletions (n = 13) that lead to the synthesis of a shortened protein. Missense variants rank second in frequency (n = 11). Missense mutations lead to changes in the amino acid sequence of the protein. These mutations affect the structure of a protein and change the functional activity of a protein.

As the world's largest coconut producer, Indonesia has the opportunity to become the main exporter of processed coconut products. Crude coconut oil (CCO) is one of the leading processed coconut products which is currently increasing in demand. In the export market of crude coconut oil, Indonesia deals with intense competition with other crude coconut oil exporters. The objective of this study was to analyze the factors that influence the import demand of Indonesian crude coconut oil and competition between Indonesian crude coconut oil with other crude coconut oil exporters in the international market. The analytical method used was the Almost Ideal Demand System (AIDS). The results showed that the factors that influence import demand of Indonesian crude coconut oil in the international market were various and Indonesian crude coconut oil could compete with crude coconut oil from Philippine in the US and German markets. The competition was indicated by the positive cross elasticity value (substitution). The decreasing price of crude coconut oil of Philippine will reduce the market share of Indonesian crude coconut oil. Therefore, Indonesia needs to improve its marketing strategy and increase crude coconut oil production to increase Indonesian crude coconut oil exports.

PROSPECTS FOR NORTH–SOUTH TRANSPORT CORRIDOR
Authors: Prokofiev M. N. , Tokhirov M. M.
Published: June 2020

International transport corridors play a leading role in shaping an integrated global transport services market.In this context, the objective of the paper was to study the current state of North–South international transport corridor (hereinafter referred to as ITC), which connects India, Iran, the Gulf countries through the countries of the Caucasus and Central Asia with Russia and the countries of Europe. A brief review of scientific publications on the subject under consideration allows to draw a general conclusion from opinions of various authors: it is necessary not only to develop the transport corridor infrastructure, but also to solve organizational, regulatory and tariff issues. The main advantage of North–South ITC is that most of the route passes by land and the route itself is shorter than the sea route, providing thus significant acceleration of cargo delivery.As a result of development of the railway network in the Caspian region and Central Asia, today there are several options for the ITC route. The western route to Iran through Azerbaijan was examined in more detail. It is expected that the missing railway section Astara–Rasht will be completed in the nearest future. Test shipments of goods from India to Russia (and vice versa) have already been carried out via western route. The characteristics of the route options by transportation distance, delivery time and cost of cargo transportation are given. Today, cost of transportation along the western branch of ITC significantly exceeds cost of sea transportation through the Suez Canal. This and other factors, reducing the efficiency and competitiveness of transportation via ITC, it is proposed to first organize container transportation on ITC section between Russia, Azerbaijan, and Iran. Such transportations might be especially in demand for food products (including perishable goods) in direction from south to north. To this end, it is proposed to organize a scheduled container train service along Astara–Moscow–St. Petersburg route using new Freight Express 2.0 transportation technology.
