Application of Mass Spectrometry Imaging in Evaluating the Spatial Distribution of Aminoacids and Sugars in Basil Leaves upon Long-Time Exposure to Cadmium
Authors: Teles Vânia , Vendramini Pedro , Augusti Rodinei , Costa Letícia
Published: November 2022

Basil samples (Ocimum basilicum Lameaceae) were exposed to cadmium and analyzed on porous PTFE membrane, and TLC plate substrates by desorption electrospray ionization mass spectrometry imaging (DESI-MSI) for amino acids and sugars identification. The TLC plate was the best substrate for analysis of the basil leaves, with high-definition images, small extract scattering, low mass deviations, and excellent reliability in the spatial distribution of the analytes. DESI-MSI analysis identified 13 images of ions putatively annotated as amino acids and sugars with high accuracy (mass deviation between -1.97 to 1.42 ppm) in contaminated and non-contaminated leaves. In general, the amino acids and sugars (proline, histidine, glutamine, arginine, homoarginine, theanine, hexose sugars, and disaccharides) accumulated preferably in basil leaves as a defense mechanism against exposure to cadmium. Asparagine, tyrosine, glutamic acid, and phenylalanine were inhibited when exposed to the toxic element. The images obtained in this study demonstrated the spatial distribution and accumulation of amino acids and sugars in basil leaves as a response to cadmium contamination, confirming that DESI-MSI is a valuable and promising tool for metabolomics studies in plants exposed to toxic metals.

ON THE POSSIBILITY OF THE POST-TRANSITION STATE CLASSICAL TRAJECTORY PREDICTIONS OF ENERGY DEPOSITION IN THE REACTION PRODUCTS£ DEGREESOF FREEDOM
Authors:   P. I. Baranov Central Institute of Aviation Motors, LOUKHOVITSKI B. I.
Published: November 2022

The possibility of applying the method of post-transition state classical trajectory dynamic simulations to study the nascent energy distribution among the molecular degrees of freedom of the reaction products is considered on the example of a number of bimolecular reactions. The results obtained for the energy deposition in the vibrational degrees of freedom of the reaction products are compared both with the reliable experimental and theoretical data. We show that the methodology under consideration gives, in principle, adequate estimates of the energy released into vibrations; however, slight discrepancies are observed, the nature of which lies in the methodological grounds of this approach.

Quantum chemical study with the use of the multireference state-averaged complete active space self-consistent field approach was carried out to explore the reactions of CH4 and C2H6 molecules with O2 in dfferent electronic states relevant for plasma-assisted combustion and plasma-chemical fuel reforming. The thermodynamically and kinetically favorable reaction pathways and possibilities of intersystem crossings have been detected. The key energy barriers were refined employing the extended multiconfiguration quasi-degenerate second-order perturbation theory. These results were compared with the previous theoretical findings. Appropriate thermal rate constants for revealed channels have been calculated employing variational transition-state theory and capture approximation with allowance for possible nonadiabatic transitions.

The time profiles of nonequilibrium radiation of electronically excited state of carbon monoxide CO (a3Πr) formed in the oxidation of methane behind shock waves at high temperatures were registered for the first time. The experiments were carried out in mixtures of CH4 with N2O and O2 in argon at temperatures of 2200—4200~K and pressures of 240±40~kPa. Intensive peaks of ultraviolet (UV) radiation from the Cameron bands of the CO molecules at a wavelength of 216 nm, sharply increasing with the temperature raise, were recorded. Simultaneously with the CO emission signals, absorption profiles of atomic oxygen at a~wavelength of 130.5~nm were recorded using atomic resonance absorption spectroscopy (ARAS) technique. To determine the quantitative concentration of the electronically excited state of CO, a series of calibration experiments was carried out in mixtures of~5\% and 10\% CO in argon at temperatures of 4000—5000~K. The analysis of the obtained data was carried out using a submechanism of formation and consumption of CO (a3Πr) during the oxidation of hydrocarbons, which was developed earlier and introduced into the existing modern complex kinetic mechanisms.

The effect of various hydrocarbon additives, dissociating with methyl radical formation, on acetylene decomposition over the wide range of temperatures was studied. Methane, ethane, propane/butane mixture, dimethyl ether (DME), and diacetyl were considered. The experiments with acetylene doped with methane, DME, and diacetyl and diluted with argon heated by shock wave up to 1700—2200~K have shown the acceleration of soot formation with the presence of additives. Kinetic modeling presented in this work is in agreement with experimental data. For the nondiluted mixtures of acetylene with additives, the simulation results have shown that the effect of the considered additives on acetylene decomposition strongly depends on temperature. Under conditions of low temperatures, 1000—1200~K, and atmospheric pressure, the addition of DME and diacetyl leads to a significant promotion of acetylene decomposition, while the addition of methane slows down the process. At higher initial temperatures of 1700—2000~K, methane and DME are the most effective promoters whereas ethane and propane/butane are the best inhibitors of acetylene decomposition and subsequent soot formation. Kinetic reasons for such opposite effects of different additives at different temperatures are discussed.

To understand the behavior of the optical properties of soot in the visible and near-infrared spectral range, it is crucial to determine the magnitude of their emission and absorption. Such information is necessary for a development of diagnostic methods for soot. We measured the absolute value of the refractive index functions of soot nanoparticles E(m,1064) at a wavelength of 1064~nm as well as the ratio of the refractive index functions at laser wavelengths of~532 and 1064~nm in a premixed acetylene/air flame (equivalence ratio~1.8) using laser-induced incandescence (LII). The results have shown that E(m,1064) increased with the flame height from~0.19 to~0.53. Depending on the height above the burner, the ratio of E(m,1064)/E(m,532) increased from~1.12 to~1.55. These changes in the optical properties are attributed to differences in the soot structure, such as the different distances between graphene planes inside soot crystallites, which decreased from~0.43 to~0.36~nm as the height above the burner (HAB) increased from~5 to~20~mm. The presented data provide comprehensive information about the optical properties of soot in a premixed acetylene/air flame depending on the HAB and make it possible to compare the measurements of the soot optical properties in various target flames.

Формирование пористости материалов при имплантации высокоэнергетических ионов инертных газов в твердую поверхность, конденсация паров в плазме разряда с образованием наночастиц, образование доменов в ферроэлектриках, зарождение пульсаций турбулентности и другие процессы можно моделировать, формулируя кинетические уравнения в частных производных: Колмогорова–Феллера, Смолуховского или Фоккера–Планка. В работе рассматриваются процессы фазовых переходов на начальной стадии с помощью компьютерного моделирования. Кластеризация зародышей новой фазы и их броуновское движение анализируются методами стохастической молекулярной динамики на основе решения стохастических дифференциальных уравнений для траекторий случайных процессов, которыми описываются модели неравновесных стадий зародышеобразования, в результате получаем распределения плотностей вероятности или кинетических функций распределения, позволяющих рассмотреть механизмы возникновения неравновесных состояний начальной стадии фазового перехода 1-го или 2-го рода. Распределения кластеров (капель конденсации) по размерам отражают роль неустойчивостей фазового перехода, приводящих к формированию неравновесной бимодальной зависимости числа наночастиц от размера, для карбида кремния моделирование может быть учтено при получении как наноразмерных аморфных порошков, так и тонких покрытий. Образование пористости в кристаллической решетке при взаимодействии потока инертных газов и их имплантации в тонкие слои поверхности твердого образца приводит к образованию слоев аморфизации покрытия. Накопление деформаций в решетке за счет пористости зависит от энергии ионов и температуры с поверхности. Новым в характеристике процессов фазового перехода являются «структуры» самоорганизации, долгоживущие пространственно-временные образования в многомерных фазовых пространствах стохастических динамических переменных, таких как размеры частиц, скорости, координаты и др., связанные с моделями кластеризации (или нуклеацией). Алгоритмы численного метода устойчивы, метод стохастической молекулярной динамики для непрерывных траекторий дополнен статистическими алгоритмами потоков Пуассона для скачкообразных случайных процессов. Рассмотрены флуктуации заряда на зародышах капель в разряде и локальные напряжения, вызываемые пористостью в кристаллической решетке образца, а также уточнение коэффициента теплопроводности пористого карбида кремния для высоких температур.

Низкотемпературная неравновесная плазма является эффективным инструментом для ускорения химических процессов, связанных с горением, и в настоящее время ведутся активные исследования плазменного зажигания и плазменного горения. Диэлектрический барьерный разряд (ДБР) представляет особый интерес в этой области благодаря относительной простоте технической реализации и способности легко интегрироваться в различные конфигурации газовых потоков. Для изучения свойств пламен с ДБР была создана горелка, обеспечивающая минимальный контакт газовой смеси со стенкой после прохождения области разряда. Были проведены измерения концентраций озона на выходе разряда при пропускании через ДБР 02 и смеси 02/СН4. Проведено сравнение влияния кварцевого и стеклянного барьера на эффективность генерации 03. С помощью газоанализатора GMS810 осуществлялось измерение концентраций NO и NO2 в пламени метановоздушной смеси при внедрении ДБР в зону горения для нескольких коэффициентов избытка топлива p. Продемонстрировано влияние ДБР на увеличение скорости распространения пламени метановоздушной смеси. При включения разряда наблюдалось уменьшение высоты факела, обусловленное увеличением скорости выгорания метана. Высота факела при p = 0,762 без разряда была практически равна высоте с включенным разрядом, но при меньшем p = 0,692, что указывает на одинаковую скорость распространения пламени в этих двух случаях. На основании этих результатов был сделан вывод о росте скорости распространения пламени на 26% при внедрении ДБР в зону горения.

The experimental study of the mechanism and characteristics of ignition was performed for a group of gel fuel compositions. Fuels based on oil-filled cryogels were prepared, which differ in component concentrations: 10\% aqueous solution of polyvinyl alcohol (PVA)\;+\;20\,\%(vol.)\;—\;80\,\%(vol.)\ of I-40 oil\;+\;2\,\%(vol.)\ of emulsifier. Combustion was initiated in a chamber with a motionless air medium at 700—1000~∘C. The patterns and characteristics of the processes occurring during the induction period were recorded by a high-speed video camera and fast- response thermocouples. It has been established that the ignition delay times vary in the range of 0.5—18 s, depending on the heating intensity (characterized by the air temperature in the chamber) and component composition of the gel fuel. The calculated minimum heat flux density required for the gel fuel ignition is 40 kW/m2.

Published: November 2022

The paper is devoted to the numerical modeling of detonation initiation in the flat channel with the profiled end-wall of the elliptic form. Mathematical model is based on two-dimensional Euler equations supplemented by the chemical kinetics model to describe the combustion of a hydrogen-oxygen mixture under the low pressure. Both the global kinetic model and the detailed Petersen—Hanson (PH) model are applied. The computations are performed on unstructured triangular grids using numerical method of second approximation order. For the calculation of time reduction, the computational algorithm was parallelized using the open source library ParMETIS to divide the computational domain. The mechanism of detonation initiation by the incident shock wave (SW) with the Mach number~2.7 is described. The results of initiation of the detonation wave (DW) for two models of chemical kinetics are compared with the identification of similarities and differences in the process.
Lutsk Fire in 1617: An Attempt to Reconstruct the Event and its Role in the Development of Religious Relations in the City (1620s — 1630s)
Authors: Dovbyshchenko Myhailo
Published: November 2022

The article deals with the fire in Lutsk, which occurred on the night of March 21–22, 1617. The author established the time and probable cause of the fire, determined the scale of the natural disaster and outlined the limits of its spread. It is noted that part of the city blocks and streets above the Styr River were destroyed or seriously damaged by the fire, along with the Market Square, two Union churches, the «Russian» hospital, the Armenian Church and the Catholic Church. It is assumed that the fire was stopped by the walls of the Okolny Castle, which, together with the Upper Castle, was not significantly affected by the fire.It was established that the residents of Lutsk, in the conditions of the spread of the fire, made efforts to save private and church property. In particular, their efforts saved the bells, icons, church utensils and other property of the Intercession and St. Nicholas Churches. At the same time, the documents attest to the facts of looting committed by army squires and individual residents of Lutsk on the Market Square and in other areas of the city in the conditions of chaos caused by the fire.It was noted that the fire caused great damage to the city economy; to overcome the consequences of the natural disaster, King Sigismund III granted a number of economic benefits. The author of the article also claims that the fire in 1617 disorganized the weakened Union Church, which had limited influence on the city residents (both burghers and nobility) and was unable to quickly restore the destroyed infrastructure under its jurisdiction. This situation created the prerequisites for the gradual transfer of land plots with objects destroyed by the fire to the hands of Orthodox and Roman Catholics. As a result, the Church of the Ascension of the Cross was built on the site of the burnt hospital, where the Orthodox brotherhood was organized, the influence of which spread far beyond the borders of Lutsk. The area where the St. Nicholas Church, destroyed by the fire, stood over time became the property of the Roman Catholics, who built a monastery on the site of the Union Church of Fatebenefratelli, which became widely known for its charity

Published: November 2022

Climate impacts and risks involve climatic impact drivers, the exposure and vulnerability of natural and socioeconomic systems, and a strong interdependency exists between climate, nature and human society. Effective climate change adaptation requires effective knowledge sharing and co-creation between communities of climate research and its users. This pilot project of the World Climate Research Programme, supported by the Asia-Pacific Network for Global Change Research and other funders, brought together experts and future leaders from the two communities to familiarise themselves with the aspects of the other discipline. The project demonstrated that knowledge-sharing and co-creation benefit everyone involved and good progress in bridging the gap between the two communities can be made. We also learned that going beyond one’s own training is challenging and fixing the gap requires both communities’ long-term and sustained commitment.

Wild representatives of the genera Sinapis L. (mustard) and Eruca Mill. (eruca, indau, rucola) belong to the crop wild relatives (CWR) and may be of interest for the inclusion in breeding. In order to identify regularities and ecological and geographical features of distribution, dot maps of distribution in the territory of Russia and neighboring states were plotted for two species of mustard and for Eruca sativa. The maps provide information about the localities of the species according to the data from herbariums and published literary sources. Eruca sativa Mill. (eruca) is a Mediterranean species, the only representative of the genus in Russia and neighboring countries, which grows in the mountainous regions of Central Asia, in the Caucasus foothills, and in the steppe part of the Crimea. In the rest of the territory, the species is represented by accidentally introduced single plants. Sinapis alba L. (white mustard) is a Mediterranean species with the European type of range; it is found as a weed throughout Russia and neighboring countries, but rarely. In the northern regions and in the Asian part of Russia, it occurs as single invasive plants. Most of the known localities of S. dissecta Lag. (Bonnier) in the considered territory is confined to the fields in steppe phytocenoses. The obtained data can be used by botanists who study the taxonomic diversity and ecological and geographical features of plants, as well as by resource scientists for identifying and involving valuable genotypes of cultivated species from the Brassicaceae family into cultivation.
A Study of Pragmatic Transfer in Criticism Strategies by Chinese EFL Learners
Authors: Bu Jiemin
Published: November 2022

Speech acts as minimal unit of discourse analysis have been the focus of second language acquisition research as they not only represent language form but also reflect cultural values of the people who perform them. Like most other speech acts, the realisation of the speech act of criticising in the target language is influenced by the native language culture. Based on Nguyen’s taxonomy of criticisms, this paper uses the peer-feedback tasks to conduct research on what kind of pragmatic transfer in criticism strategies by Chinese EFL learners occurs and how it occurs in academic setting. The oral data collected through a naturalised role-play are coded and analysed quantitatively among the Chinese EFL learner group, the native English group, and the native Chinese group. The post hoc interview is also conducted among these three groups to investigate the reasons why they choose a certain criticism strategy. This research has indicated that the Chinese EFL learner group displays indirect criticism strategies, request and suggestion more frequently than the native English group and shows indirect criticism strategies, request and suggestion with somewhat similar frequencies to the native Chinese group. These three criticism strategies show Chinese characteristics of valuing politeness, caring about the hearer’s face and spiral thinking patterns. The research has shown that there is, to some extent, pragmatic transfer in indirect criticism strategies, request and suggestion by Chinese EFL learners and how pragmatic transfer in these three criticism strategies occurs in academic setting. Keywords: interlanguage pragmatics, pragmatic transfer, criticism strategy, Chinese EFL learner

Higher aquatic vegetation occupies small areas (up to 6 %) on loess «islands». The plant communities have been identified. Plant communities have typical species composition and structure for Polissia vegetation. The classification scheme of plant syntaxons is based on the floristic-ecological approach. It was established that the higher aquatic vegetation of the loess «islands» reservoirs is represented by three classes: Lemnetea, Potametea and Phragmito-Magnocaricetea, belonging to five orders, 10 unions and 34 associations. The distribution of plant communities was clarified. The comparison of the higher aquatic vegetation classes representation of the loess «islands» water bodies in the Chernihiv Polissia was carried out. The greatest phytocenotic richness and diversity is noted in the Phragmito-Magnoсаricetea class, while the least is observed in the Lemnetea and Potametea classes. The Lemnetea class communities occur mainly in shallow water in the water bodies of all loess «islands». The vegetation of free-flowing aquatic plants belonging to the Lemnetea class is mostly represented on the territory of the Berezna-Mena-Sosnytsia and Ripky-Chernihiv loess «islands». This is due to the larger hydrological network on these loess «islands». The Potametea class communities are distributed only on three loess «islands» of the Chernihiv Polissia. Mykhailo-Kotsyubinsky loess «island» has the smallest area among the «islands», the most transformed landscapes and a small number of water bodies. Therefore, there are no Potametea class communities here. In conditions of high humidity and high mineral nutrition, the communities of the Phragmito-Magnocaricetea perennial herbs develops, first of all, of the Magnocaricetalia order. The significant distribution of Phragmito-Magnocaricetea communities is due to the presence of favorable conditions for their development: low-lying areas of floodplains that are periodically flooded, coastal shallows with significant fluctuations in the water level during the growing season. A comparison of the syntaxonomic diversity of the higher aquatic vegetation classes was carried out. The centers of phytocoenotic richness were determined. The reservoirs of the Mykhailo-Kotsyubinsky loess «island» are characterized by the least syntaxonomic diversity. There are no centers of phytocenotic opulence here.

Ancient and modern 183 varieties of winter and 23 spring types of development of bread wheat (Triticum aestivum L.) selected Ukrainian state institutions and private companies are characterized by alleles of Ppd-D1, Ppd-B1, and Ppd-A1 genes. Allele-specific molecular markers, proposed in the scientific literature, were used to identify carriers of the Ppd-D1a, Ppd-D1b, Ppd-D1c, Ppd-D1d, Ppd-B1a, Ppd-B1c, Ppd-A1b alleles. According to the results of PCR analysis, the most widespread among the studied winter cultivars was observed in the dominant allele Ppd-D1a (91.9 %) with a range from 80.0 % in the sampling of varieties of the Northeast (Kharkiv, Sumy) to 95.0 % in southern cultivars (Odesa, Kherson), and in spring – recessive Ppd-D1c (43.5 %). The share of carriers of various recessive alleles of the Ppd-D1 gene among spring varieties is 73.9 %, and among winter – 8.1 % and, except for Borovitsa and Talisman consists of cultivars created by the late 60 – early 70 years of last century. The frequencies of the Ppd-B1a and Ppd-B1c alleles are quite small. The Ppd-B1a allele was found only in three spring varieties, and the Ppd-B1c allele in 5 winter varieties and spring wheat Struna Mironivska, except for the latter cultivar, in all cases found together with the Ppd-D1a allele. The Ppd-A1 gene was present in a recessive state in all studied sorts. Seven different homozygous Ppd-1 genotypes have been determined in the studied cultivars. Samples of winter and spring varieties differ significantly in the quantity and frequency of specific Ppd-1 genotypes. The presence of varieties with monogenic dominant Ppd-D1a or Ppd-B1c control of traits and digenic dominant Ppd-D1a Ppd-B1a genotypes has been marked in spring wheat, as well as monogenic dominant for Ppd-D1a and digenic dominant for Ppd-D1a in winter wheat varieties. In spring cultivars the share of carriers of recessive alleles of Ppd-1 genes is several times higher (69.6 %) than in winter varieties; conversely, the samples of winter varieties have significantly more dominant alleles (91.9 %). Such differences in genotype frequencies are due to the timing of sowing and duration of the natural day at the latitude of the growing region during the growing season of winter and spring varieties.

Streptomyces roseochromogenes NRRL 3504 is the only known producer of aminocoumarin antibiotic clorobiocin – an inhibitor of bacterial DNA-gyrase and topoisomerase IV. Sequencing of NRRL 3504 genome revealed a plethora of specialized metabolite biosynthetic gene clusters (BGCs) within the latter, attesting to the significant potential of this species for the production of various as-yet-unknown bioactive compounds. Here we report bioinformatic analysis of NRRL 3504 genome aimed to better understand what kind of small molecules this strain could produce and genetic mechanisms that may limit their production. In addition to the most commonly applied bioinformatic service for BGCs detection antiSMASH, we turned to alternative tools for secondary metabolome in silico analysis such as PRISM, DeepBGC, ARTS, SEMPI and GECCO. While different genome mining applications pointed to a common core set of BGCs within the NRRL 3504, each tool having its own algorithm of BGCs detection also discovered certain number of non-overlapping clusters. This was especially true for machine learning tool DeepBGC that unearthed the biggest number of BGCs. To summarize the obtained results we used BGCViz tool, which visualizes and integrates BGC annotations from various sources by using genomic coordinates. We discuss the genetic and structural diversity of the BGCs and outline the most interesting, in opinion, targets for further investigations. Most of the described BGCs are most likely silent due to very low or zero transcription. Therefore, it might be needed to find the ways to activate the transcription of the BGCs of interest. To this end, we mined NRRL 3504 genome for the orthologs of global regulatory genes known to be involved in regulation of specialized metabolism of S. coelicolor A3(2). We were able to identify almost all plausible global regulators of interest in NRRL 3504, implying that overall scheme of regulation of specialized metabolism in A3(2) and NRRL 3504 might be similar. Results of our work set the stage for a more detailed experimental scrutiny of silent specialized metabolome of NRRL 3504.

Meadow-steppe plant communities of the nature reserve territories of the National Nature Park “Northern Podillia”, in particular, the “Makitra” reserve located outside the steppe zone, as a result of the decrease in economic activity and the effect of the passive protection mode (absolutely reserved regime) of rare plant species populations are under the threat of spontaneous afforestation and may lose their original purpose. The changes that accompany the sylvatization process concern all components of the biogeocenosis. In the process of degradation of the grass phytocenosis, the morphological features and physical and chemical properties of the soil undergo changes too. Soil profiles were taken on the northeastern slope of Makitra Mountain, in the meadow-steppe plant association. We revealed that 12–15 years after the beginning of afforestation with Scots pine, chernozem under the primary meadow-steppe plant association possesses apparent signs of degradation throughout the depth of the profile: (1) degradation of surface organogenic horizons (Hc + Hd); (2) lowering the depth of the carbonate level in the profile by 10–15 cm; (3) loss of organic matter by 30–50 %; (4) reduction of cation exchange capacity by 15–20 %; (5) leaching of CaСО3 (>50 % from the H horizon) and other macro- (K, Na, Mg, Fe, Al) and trace elements (Cu, Zn, Mn, Ni, Pb) (up to 10–30 %). The intensity of leaching processes at the study time-point remains high, evidenced by the higher content of amorphous silica, aluminum, and water-soluble carbon in the soil at the afforestation stage, compared to virgin chernozem. The obtained results provide basics for predicting the soil development from typical chernozem under virgin meadow-steppe phytocenosis to leached chernozem (forest chernozem according to Travleev (2008)) in the process of overgrowing with Scots pine. In both cases, the soil-forming process is still within the framework of the humus-accumulative process of soil formation. However, taking into account the high intensity of degradation processes detected at the time of the research, there is a possibility of a significant increase in signs of leaching, which will indicate an impact on the development of the soil profile together with the chernozem (accumulative) and podzolic soil-forming processes.

Literature data on the effect of interval fasting (IF) on the morphological and functional changes in the pancreas, especially its exocrine part, are rare. The aim of our work was to study the morphological changes in the exo- and endocrine pancreas of adult rats after the influence of IF. The study was carried out on 24 male Wistar rats at the age of 15 months. Experimental rats were on IF: 1 day – complete fasting / 2 days – standard diet. Access to water was free. The duration of the experiment was 28 days. Rats were decapitated under light ether anesthesia. Work with rats was carried out in accordance with the principles of the Helsinki Declaration. Histological preparations were made from the central part (the body of the gland) according to the standard method. From micropreparations of the gland, photographs were taken using a digital camera. Gland morphometry was performed on digital images using the «Image J» computer program. It was revealed that in the exocrine pancreas of adult rats that were on IF, the area of ​​acinus, nucleus of exocrinocytes increases and the number of nucleolus increases, the nuclear-cytoplasmic ratio increases. In the endocrine pancreas of experimental rats, more intense morphological changes occur, namely: its relative area probably increases (by 108 %), the average number of Langerhans islets increases (by 44 %) and their linear dimensions increase, the number of endocrine cells increases (by 20 %). Also in the gland of these animals, a decrease in the relative area of ​​the stroma (by 21 %) and the stromal-parenchymal index (by 28 %), as well as a decrease in the width of the layers of the interlobular (by 28 %) and interacinus (by 34 %) connective tissue, which improves conditions for the course of metabolic processes. Thus, the effect of IF is accompanied by the appearance of morphological signs of an increase in the activity of both the exocrine and endocrine (to a greater extent) pancreas in adult rats. The data obtained may be of interest for practical medicine when deciding whether to prescribe this type of hunger strike to people with reduced pancreas function.

Los ácidos nucleicos (ADN y ARN) tienen la importante función de almacenar, expresar y transmitir la información genética de los seres vivos. El ADN actúa como "repositorio" de la información, en el núcleo de las células, y el ARN mensajero (mRNA) transmite esa información al sitio de síntesis. Esta propiedad permite utilizar al mRNA como agente terapéutico o para la generación de inmunidad contra organismos patógenos. En particular es interesante el diseño de vacunas basadas en mRNA que se han probado con éxito contra el covid-19, además del uso del mRNA contra enfermedades no infecciosas, entre ellas la diabetes tipo 1, la hemofilia, el asma y ciertos tipos de cáncer, incluyendo el melanoma. Las posibilidades terapéuticas del mRNA son muy amplias.
