Среди наиболее значимых заболеваний человека 4-е место, после сердечно-сосудистых, онкологических заболеваний и сахарного диабета, занимает остеопороз. Целью нашей работы было сравнение влияния 3- и 6-месячного введения аторвастатина (ATV) и α-кальцидола (α-К) на морфологические показатели костной ткани лабораторных крыс. Эксперимент проводился в течение 3-х и 6-ти месяцев на 240 лабораторных крысах, разделенных на 5 групп: интактные; «плацебо» (внутрижелудочное введение эквивалентного препаратам объёма 1% крахмала); животные, внутрижелудочно получавшие только ATV; животные, внутрижелудочно получавшие α-К и животные, внутрижелудочно получавшие ATV и α-К. Эвтаназия осуществлялась под эфирным наркозом. Кусочки бедренной кости размером 0,5 см выпиливали в области проксимального метафиза, а ветви нижнечелюстной кости – диастемы. Зону роста пропитывали серебром по Лилли и окрашивали по Ванн-Гизону. Исследование гистосрезов проводили на микроскопе Olympus BX-40. Размер вновь образованной костной ткани, окрашенной солями серебра в черный цвет, измеряли с помощью программы ImageScope-M. Количество сосудов считали в 10 полях зрения с расчетом среднего значения. Статистический анализ данных проведен с помощью пакета прикладных программ R 3.6.3 с учетом соответствия закону нормального распределения и применением поправок на множественные исследования. Отличия считали статистически значимыми при p-значении <0,05. В результате исследования сделаны следующие выводы: 1. Зона роста костной ткани бедренной кости увеличивается через 6 месяцев больше, чем через 3 месяца эксперимента. 2. Основные изменения в исследуемых показателях под влиянием вводимых лекарственных средств происходят уже через 3 месяца и остаются практически неизменными по сравнению с 3 месяцами к 6 месяцам эксперимента.

Целью работы было оценить влияние перорально вводимого полуочищенного каррагинана (E407a) на гидрофобный участок фосфолипидного бислоя клеточных мембран лейкоцитов периферической крови. Материал и методы. Флуоресцентный зонд (2-фенилфенантро[9,10-d]-1,3-оксазол) был использован для оценки состояния липидного бислоя мембран лейкоцитов, полученных от 8 взрослых крыс-самок линии WAG, которые перорально получали полуочищенный каррагинан в дозировке 140 мг на кг веса в течение 2 недель, и 8 контрольных животных. Результаты. В ходе проведения работы установлено, что заметных изменений формы спектров флуоресценции зонда в ответ на пероральное введение полуочищенного каррагинана не наблюдалось. Это указывает на то, что пероральный прием E407a не вызывает изменений протонодонорной способности среды в липидных мембранах лейкоцитов в области расположения зонда. Уменьшение интенсивности флуоресценции зонда у крыс, которым перорально вводили пищевую добавку E407a, связано с уменьшением количества молекул зонда, которые связались с мембранами в течение 1 ч инкубации. Заключение. Пероральное употребление полуочищенного каррагинана не вызывает изменений гидратации гидрофобного участка фосфолипидного бислоя мембран лейкоцитов.

Цель – изучение способности к пленкообразованию C.albicans и E.coli, выделенных у пациенток с вагинитами, а также их чувствительности к доксициклину, амоксиклаву, офлоксацину, флуконазолу, клотримазолу в планктонном виде и в составе моно- и микст-биопленок. Материал и методы. В ходе исследования изучались свойства и способность к пленкообразованию C.albicans 2924 и E.coli 2646, выделенных со слизистых у пациенток с клиническими признаками вагинита. Определялись минимальная подавляющая концентрация (МПК) и минимальная бактерицидная концентрация (МБК) антибиотиков для планктонных форм микроорганизмов: бактерий и кандид в составе моно-биопленки, а также в составе микст-биопленки. Результаты. Выявлено, что исследуемые микроорганизмы способны образовывать биопленку. При изучении чувствительности микроорганизмов в составе биопленок (БП) выявлено, что МПК препаратов для моно-биопленок возрастают в 2-4 раза, для микст-биопленок в 2,5-8,5 раза относительно МПК препаратов для планктонных форм E.coli и C.albicans. Бактерицидные концентрации амоксиклава, офлоксацина, доксициклина, флуконазола, клотримазола для планктонных форм являются неэффективными для биопленочных форм этих же микроорганизмов. Заключение. Определение чувствительности микроорганизмов в составе БП к антибактериальным препаратам необходимо для назначения рациональной антибиотикотерапии и разработки протоколов эмпирической антибактериальной терапии. Актуальным является изучение механизмов резистентности бактерий в составе биопленки, разработка новых фармацевтических препаратов с высоким потенциалом действия на биопленки, так как стандартная терапия высокими дозами антибиотиков (АБ) токсична для макроорганизма, что диктует необходимость апробации новых средств.

Soil erosion by water has become a relevant issue at global scale. In the last years this phenomenon witnessed a spectacular extension and its effects are becoming more disturbing.The majority of studies on water erosion and land degradation in Algeria do not or slightly integrate spatial analysis techniques by GIS, to provide more knowledge and mapping of these phenomena.In this study, geographic information systems were used to develop a number of thematic maps (slope, topography, hydrographic network map) and to assess and map the phenomenon of water erosion using the universal soil losses equation (USLE) in the Djelfa region,central Algeria. This watershed is characterized by a great irregularity in precipitation, steep slope and low vegetation cover, which makes it very vulnerable to erosion.The aim of thisstudy is to couple a GIS tool withthe USLE model to determine the rate of erosion by runoff (0.31 t/ha/year on average), to map the areas at risk of water erosion in the region of Djelfa, and disseminate the results for adequate decision-making.

In order to measure the reproductive performances and numerical productivity of Ouled Djellal ewes, and to determine the influence of non-geneticfactors onthese parameters, a database wasestablished, by monitoring 2710 ewes, belonging to 12 farms, representative of two dominant modes of reproduction in the Chlef region. Body condition scores (BCS) of groups ofewes put in reproduction were carried out to compare the performances under breedingconditions. Thestudy showed a fertility and prolificacy of 91.04% and 115.35% in the breeding mode of lambing per year in spring, against 59.35% and 103% in the traditionalsystem with lambingspread over the year (the ram is permanently present in the herd). The body condition and body reserves of the ewes varied according to the lambing season and the farmsmanagement (feed system). The interaction between the body condition of the ewes at mating and their reproduction performances was evident. Indeed, as BCS at mating increased, fertility, prolificityand productivity improved. The ewes with BCS at mating higher than or equalto3 produced the best performance, whereasthe ewes with BCS lower than 3, were less fertile, less prolific and less productive. On average the productivity of Ouled Djellal ewes was 105.03% and 61.10%, respectively,in the first and second mode of reproduction. The main sources of variation as well as their interactions, were highlighted in this study.

Published: March 2021

The massive expansion of oil palm plantations has social, economic and environmental impacts. One of the social impacts caused by the expansion of palm oil plantations is social conflict, so the purpose of this research is to identify and analyze the relationship between expansion and conflict in oil palm plantations in Terantang Manuk Village, Pelalawan-Riau. Palm oil plantation expansion is one of the factors for the emergence of social conflicts in rural areas. This research was conducted using a qualitative approach. Primary data were collected through in-depth interviews with the determination of the informants using purposive sampling technique. There were 16 informants who were interviewed, consisting of the village head, hamlet head, customary chairperson (ninik mamak), community leaders, chairperson of Cooperative Terantang Jaya Mandiri (TJM), leader of youth organization, and leader of college student organization. Secondary data quoted from archives of public correspondence, court decisions, and information from the mass media. The results of this study indicate that there are two types of expansion, namely informal expansion and formal expansion. Informal expansion only causes land conflicts, while formal expansion causes more diverse conflicts, namely land conflicts and conflicts due to oil palm plantation activities.

Published: March 2021

Aims: The objective of this retrospective cohort study was to provide an
overview of the utilization of originator and biosimilar infliximab in
the Netherlands. Methods: All infliximab dispensings were selected from
the PHARMO In-patient Pharmacy Database from 2002-2018. Descriptive
analyses were performed in order to characterise initiators and to
describe switching patterns over time. Results: Overall, 3,840 patients
with 61,274 infliximab dispensings were identified. 2,496 patients
initiated an originator infliximab and 777 patients initiated a
biosimilar infliximab. Overall, 57% of the patients was female and mean
age was 43.2 years. Both originators and biosimilars were mostly
prescribed by gastroenterologists, followed by internists and
rheumatologists. After market authorization of the first biosimilar the
proportion of new patients initiating the biosimilar increased from 39%
in 2015 to 91% in 2018. Out of 704 patients eligible for switching 34%
switched. Among switchers, the proportion of females was 60% and mean
age at index was 45.1 years. Among non-switchers, 55% was female and
mean age was 39.8 years. The median time to switch was 1.7 years and
switchers were most frequently initiated on infliximab by a
rheumatologist (42%), while non-switchers were most frequently
initiated by a gastroenterologist (42%). Conclusions: The results of
this large population-based cohort show an increase in biosimilar
initiation in daily clinical practice. The number of switchers remains
relatively low as non-medical switch is not encouraged in the
Netherlands.

Published: March 2021

Background: Catheter ablation for atrial fibrillation (AF) treatment
provides effective and durable pulmonary vein isolation (PVI) and is
associated with encouraging clinical outcome. A novel CF sensing
temperature-controlled radiofrequency (RF) ablation catheter allows for
very high-power short-duration (vHP-SD, 90W/4 seconds) ablation aiming a
potentially safer, more effective and faster ablation. We thought to
evaluate preliminary safety and efficacy of vHP-SD ablation for PVI
utilizing a novel vHP-SD catheter. The data was compared to conventional
power-controlled ablation index (AI) guided PVI utilizing conventional
contact force (CF) sensing catheters. Methods and Results: Fifty-six
patients with paroxysmal or persistent AF were prospectively enrolled in
this study. Twenty-eight consecutive patients underwent vHP-SD based PVI
(vHP-SD group) and were compared to 28 consecutive patients treated with
conventional CF-sensing catheters utilizing the AI (control group). All
PVs were successfully isolated using vHP-SD. The median RF ablation time
for vHP-SD was 338 (IQR 286, 367) seconds vs control 1580 (IQR 1350,
1848) seconds (p<0.0001), the median procedure duration was
vHP-SD 55 (IQR 48-60) minutes vs. control 105 (IQR 92-120) minutes
(p<0.0001). No differences in periprocedural complications
were observed. Conclusions: This preliminary data of the novel vHP-SD
ablation mode provides safe and effective PVI. Procedure duration and RF
ablation time were substantially shorter in the vHP-SD group in
comparison to the control group.
Countercurrent chromatographic isolation of 11´-γ-tocomonoenol from and detection of novel minor tocochromanols in pumpkin seed oil
Authors: Kröpfl Alexander , Vetter Walter
Published: March 2021

A non-refined, organic pumpkin seed oil (PSO) was chosen for the
isolation and structure verification of the rare vitamin E compound
γ-tocomonoenol (γ-T1). Initial measurements indicated the presence of
~0.4 mg γ-T1 per 100 g pumpkin seed oil. Saponification
of ~2 L pumpkin seed oil, followed by repeated
countercurrent chromatography (CCC) with the solvent system
n-hexane/benzotrifluoride/acetonitrile (10:3.5:6.5,
v/v/v) and silica gel column chromatography enabled
the isolation of 6.8 mg γ-T1 with a purity of 96.0%. Structural
analysis by H NMR spectroscopy and gas chromatography
with mass spectrometry (GC/MS) of the γ-T1 isolate confirmed the
presence of a double bond in C-11´-position (11´-γ-tocomonoenol). Next
to γ-T1, CCC fractionation enabled the detection of 18 different
tocochromanols, many of which were reported for the first time in
pumpkin seed oil. This unmatched variety covered among others
α-/γ-tocopherol, α-/γ-tocomonoenol, two α- and two γ-tocodienol isomers,
α-/γ-tocotrienol as well as the rare 11´-β-tocomonoenol (β-T1) and δ-T1.
Three uncommon tocochromanols were also detected whose origins and
structure remained unclear.
Growth, winter preparations and timing of emergence in temperate zone Odonata: control by a succession of larval response patterns
Authors: Norling Ulf
Published: March 2021

As warm-adapted insects of tropical origin, Odonata cope with cold periods by seasonal regulation and diapause. A model for larval-overwintering species is proposed with three response patterns related to the timing of emergence, which can be predicted from seasonal cues during the last few stadia. For emergence during the present season, there is an often time-constrained preemergence development, accelerated by long days and higher temperatures. In regulatory development, emergence is postponed to the next season, and a complex of diapause-like delays controlled by photoperiod and temperature prevents premature emergence. Instead, development converges on a winter diapause in sizes suitable for emergence during the following year. Long days are particularly delaying, and thermal responses are variable, sometimes inverted. In early development, with rapid growth, emergence is usually not predicted to season, but short-day winter diapauses may occur, and precocious preparations for a penultimate winter may be predictive. Thermal responses are steep, extremely so if a short-day diapause is suppressed by higher temperatures. Other physiological and also behavioural properties may differ between response patterns. Changes in photoperiod and temperature control the timing of seasonal events, and the transition from regulatory to pre-emergence development follows the increase in temperature and photoperiod after winter, which is an important time-setter. Interactions of larval size, photoperiod, temperature and previous changes affect development rate, and long-term constant conditions often end in regulatory diapauses. Proximate mechanisms of cohort splitting and the implications of the model for design and interpretation of experiments are discussed.

Land resources in India are under severe pressure and it is widely believed that marginal lands are being brought under cultivation. The extent of such changes needs to be known for better land use planning decisions. The present study illustrates the spatio-temporal dynamics of land use land cover of Nagjhari watershed in Bhatkuli block of Amravati, Maharashtra. Multi-temporal high resolution of Sentinel and Landsat satellite data were used to identify the significant positive and negative Land use land cover changes over a decade of 2007 to 2017. From 2007 to 2017, the ‘habitation’ class increased by 34% due to increasing population pressure. There was a decrease in ‘wasteland’ by 10.3%, while the area under ‘agriculture’ decreased by approximately 4.7% because of the increased area under ‘habitation’ and ‘water body’ at Nagjhari watershed. The biggest change occurred in land use class ‘water body’ increased sharply from 2013-17 by 62.7 per cent due to consequence of state policy of watershed development that was implemented after 2014. The forest class recorded maximum loss (18.3%) due to increasing population maximum land converted into habitation. The study shows overall classification accuracy as 85.46% and kappa coefficient (K) of 0.85. Kappa coefficient indicated that land use land cover assessment from remote sensing data show the best accuracy. These finding will help in deciding land use policy for future and its impact on land management of the watershed.

A pot experiment was conducted to understand the effect of soil applied silicon on maize crop growth under alkaline stress. The treatment consists of silicon levels (kg ha-1) – 0, 100 and 150 and alkaline stress levels (mM) – 0, 25, 50, 75. The pots were arranged in completely randomized block design in factorial arrangement with three replications. The result revealed that the shoot and root length and chlorophyll content of maize were reduced with increasing alkaline stress. The percent reduction due to alkaline stress on shoot and root length was to tune of 3.6 to 15.8 and 8.9 to 35.8, respectively and chlorophyll content 11.2 to 35.7. The sodium ion content increased, but potassium content and K Na-1 ratio decreased with alkaline stress. The gas exchange parameters viz., photosynthetic rate, stomatal conductance and transpiration rate were significantly decreased with alkalinity levels. The adverse effect of alkalinity on maize was turnround with intervention of soil applied silicon. The percent increase due to silicon intervention ranged from 4.3 to 12.6 in photosynthetic rate, 4.5 to 14.5 in stomatal conductance, 6.3 to 21.4 in transpiration rate, 7.0 to 20.9 and 8.4 to 29.3 in shoot and root potassium, 19.4 to 33.5 and 20.6 to 55.9 in shoot and root K Na-1. The percent decrease in sodium concentration in shoot and root ranged from 8.6 to 14.2 and 4.3 to 23.7. Between 100 and 150 kgs of silicon applied, the desired result was achieved with 150 kg Si ha-1. It is recommended to apply 150 kg Si ha-1 to maneuver the ill effects of alkalinity on maize.

An experiment was conducted during rabi 2012-13 at research farm of Indian Institute of Millet Research (IIMR), Rajendranagar, Hyderabad, Telengana State, India. The experiment was laid out in a split plot design, replicated thrice, with 10 Sorghum genotypes as main treatment Well-watered (WW) and Water-stress (WS) conditions) to examine the potential of Sorghum genotypes to adapt to the post flowering drought. 10 genotypes are sub-treatments CRS 4, CRS 19, CRS 20, PEC 17, CSV 18, M 35-1, Phule chitra, Phule moulee, EP 57 and CRS 1). Among the four stages viz., 10, 20, 30 and 40 days after flowering (DAF), the GLAR (stay green trait) at 10 DAF had a positive and higher significant correlation with grain yield (r=0.66). So, GLAR at 10 DAF is most appropriate stage to screen for post flowering drought tolerance. Among the yield components, number of grains per panicle, grain weight panicle-1 and harvest index (HI) are significantly and positively correlated with grain yield and therefore it can be ascribed that the genotypes, which partitioned more assimilates into economic parts and in which grain filling is high, recorded more grain yield. The overall yield reduction due to moisture stress during the post flowering drought was 10% and it ranged between 8-12% among the genotypes. This indicates that the genotypes used in the present study are relatively drought tolerant. The genotypes CSV 18 and Phule moulee registered least yield reduction (8%) in grain yield due to post flowering drought followed by PEC 17 and M 35-1 which registered 9% yield reduction. However, the overall grain yield of PEC 17 and M 35-1 was more than CSV 18 and Phule moulee even under moisture stress conditions.

The metallurgical industry is one of the major pollution sources of natural ecosystems. Now the slag dumps of non-ferrous industries occupy huge areas all over the world. The purpose of this literature review was to assess the knowledge degree of the soils and vegetation formed on the non-ferrous metallurgy slag dumps. Most of the research was carried out for the dumps of the copper-smelting (including old dumps) and lead-zinc industries, the dumps of the nickel and aluminum industries have been studied to a lesser extent. The composition of non-ferrous metallurgy slags, the issues of soil pollution with heavy metals, their bioavailability were discussed. The influence of heavy pollution on the biodiversity of pioneer plant communities on the slag dumps of non-ferrous metallurgy and the floristic composition for abandoned copper ore deposits are noted. The experience of Russian scientists in the reclamation of an aluminum sludge dump and Chinese scientists in the reclamation of zinc production slag dumps are considered. The possibility of introducing waste from the copper smelting slag recycling waste into natural ecosystems was discussed. The analysis of literature revealed gaps in knowledge about the gradual formation of the soil and vegetation on man-made landscapes, about the plant biodiversity in conditions of heavy pollution, ways of their adaptation, and the heavy metals accumulation by different plant species.

ADAPTIVE HOUSE DESIGN AND PEOPLE’S HABITS IN ACHIEVING THERMAL COMFORT IN GAYO HIGHLAND ACEH, INDONESIA
Authors: Meutia Erna , Sari Laina Hilma
Published: March 2021

The Gayo Highland is one of the districts in Aceh Province, Sumatra. Due to the topography, this area has a lower  temperature compared than the flat and coastal areas in Aceh. The thermal comfort that is felt is based on a person's mental condition and how he expresses his satisfaction with his thermal environment. In other words, it shows how humans adapt to their thermal environment. Thermal comfort based on human adaptation is known as adaptive thermal comfort. The form of dwelling for the Gayo Highland community has shifted and changed from traditional dwelling to Transitional and Modern forms that influence the Gayo Highland community's adaptation to achieve thermal comfort. Therefore, this paper aims to investigate the house design in Gayo highland in providing warmth to the occupants naturally in the cold environment. Another aim of this study is to investigate the people's habits in warming up the body to deal with the low air temperature in the area.  This study shows how the local people adapt themselves through the house element and daily habit to gain the internal thermal comfort.
El verblador: propuesta de traducción al Español del poema “Jabberwocky”, de Lewis Carroll, teniendo en cuenta los aspectos formales de la rima y la métrica
Authors: López Murcia Miller Eduardo
Published: March 2021

Las maneras en la que se ha traducido el poema “Jabberwocky” de Lewis Carroll, varían tanto en la estructura como el contenido. Al tratarse de un idioma que es distinto cultural y morfológicamente, y de la gran brecha temporal que existe desde su publicación, las palabras sinsentido que el poema tiene se han resuelto y adaptado de formas diversas, pero todas estas traducciones coinciden en que los aspectos formales no fueron tenidos en cuenta a la hora de su realización. Esta propuesta creó una traducción que acata en lo más posible el sistema métrico y de rima del poema original, y también las técnicas que empleó Carroll para crear los juegos del lenguaje que hacen de este poema uno de los más destacados de la lengua inglesa.

Rotor Resistance Estimator based on Virtual Current Sensor Algorithm for Induction Motor Drives
Authors: Adamczyk Michał
Published: March 2021

In this article, model reference adaptive system (MRAS)-based estimator of a rotor resistance of an induction motor (IM) is presented. In contrast to the solutions known from the literature, the reference model of this estimator uses the measured values of the phase current and the adaptive part is a virtual current sensor. The article presents an accurate description of the algorithm taking into account the discrete equations for possible practical implementation in the microprocessor system. In the first step, the impact of motor parameters to stator current estimation quality in the adaptive model was checked. Subsequently, simulation tests of the proposed rotor resistance estimator were carried out for the field-oriented control of the induction motor drive system with a model of an induction motor with fixed parameters and an induction motor with a changing main inductance according to a magnetisation curve. The analysis of the estimator’s work showed its high efficiency and insensitivity to changes in the IM main inductance.
