Ecological and Socio-Economic Value of Waterlogged Areas
Authors: Tereschenko O V , Sergienko O I 
Published: September 2021

Abstract
The article summarizes the main indicators of the value of waterlogged areas, which must be taken into account for the sustainable management of wetlands. The ecosystem functions of wetlands included in the natural capital of a region relate to hydrology, water quality, supporting food chains, and providing habitats for living organisms, including rare and protected ones. The socio-economic significance of wetlands is formed both from their consumer value and from non-productive, socio-cultural values. There is a need to develop an approach and methodology for the study of waterlogged areas, within which the assessment of the natural capital of a region will necessarily include the assessment of the non-productive values of wetlands.

Abstract
Sod-podzolic low-fertile soils (70% of the territory) are mainly widespread in the Novgorod region. According to the granulometric composition, the sown areas are mainly light and medium loamy. Technological operations include two methods of application of microbial fertilizers Azotovit and Phosphatovit: pre-sowing seed treatment (A+Ph, 2 l/t of each preparation) + foliar treatment in the phase of entering the tube (A+Ph, 1 l/ha of each preparation) together with mineral fertilizers (based on the planned yield and reduced by 50%), which contributes to an increase in oat grain production by 32 and 33%, and digestible protein by 30 and 34%, respectively, in relation to background 1 and background 2, where microbial fertilizers were not used. As an organic fertilizer, chopped straw of spring barley was plowed (4 t/ha) with addition of 10 kg of nitrogen for each ton. After harvesting cereals, a disc harrow was used to chop the straw and mix it with the soil at a depth of 0-10 cm.Taking into account the main articles of the arrival of humus (stubble-root residues of cereals and straw) in all variants of the experiment, soil fertility increased and its energy potential increased from 9 up to 16 GJ/ha.

Abstract
In the context of large-scale selection and the widespread use of methods of initial genomic evaluation of stud bulls, a careful selection of breeding pairs is of particular importance when it is necessary to consolidate animals in dairy herds according to the traits of conformation, body composition and dairy type intensity. The method of linear evaluation of physique features, adopted in Russia, coincides with the standard method system approved by the ICAR in the main approaches and characteristics. According to the results of a linear evaluation of bulls used in a herd of black-and-white cattle, it was found that the average score on the main parameters of the conformation for technologically significant traits (dairy type intensity, the condition of the animal’s limbs) has been within 5.00…5.90 (points). At the same time, the traits that characterize the main parameters of the udder of cows, depth and breadth measurements, need to be improved. Based on the results of evaluating the prepotent properties of the bulls by linear traits, the optimal structure of the dairy herd has been determined, in accordance with the presence of the main lines in the Holstein breed.

Authors: Vasiliev A S , Lebedev N V , Lebedeva P M 
Published: September 2021

Abstract
The research was carried out on the experimental field of the FSBEI of HE “Tver State Agricultural Academy” in 2019 and 2020. It was found that the application of pure microelement fertilizers Aquamix ST and Aquarin 5 allowed obtaining a statistically significant increase in the yield of green mass of meadow clover under favorable agro-climatic conditions on soils poor in microelements. The highest yield was noted on plots with clover treated with pure Aquarin 5 (57.90 t/ha) per cut. The use of Aquarin 5 increases the yield of clover by 22.20–48.80%, and in terms of mineral fertilizers in a full dose of N50P50K50 - by 4.80–24.30%. Small rates of mineral fertilizers N25P25K25 did not have a significant effect on the yield of clover, and an increase to N50 led to a negative result. The economic efficiency of the combined application of chelated and complex fertilizers is lower than the use of physiologically active substances in their pure form on soils poor in microelements.

Abstract
This paper presents the results of the studies that have been conducted to research the impact of the addition of table salt, clove oil and “Prolam” probiotic to water on improving the survival and adaptive properties of transported fish. By adding table salt and clove oil to water during the transportation of sturgeon fish, the survival rate of juvenile fish was increased by 0.4 %, and by 1.0% more in the group in which “Prolam” probiotic was added to the water in the amount of 2 ml/10 l (the fourth experimental group), compared with the control group. The adaptation time amounted to 25 minutes for the group transported in water without additives, 25 minutes for the group in which table salt was added to the water, 32 minutes for the group transported in water with clove oil added, and 20 minutes for the group transported with the addition of “Prolam” probiotic. Being further grown for 90 days, the final weight of sterbel fingerlings increased by 8.1 % when they were transported in water with the addition of “Prolam” probiotic in the amount of 2 ml/10 l. The average daily weight gain was higher in the second, third, and fourth groups by 8.4 % compared to the control group. The yield of fish products when transported with the addition of table salt was higher by 6.1%; when adding clove oil–by 3.4%; with the addition of “Prolam” probiotic–by 15.8 % in comparison with the fish transported without additives in water.

Authors: Slobodinyuk Alexei , Kiselkov Dmitriy , Elchisheva Nadezhda , Slobodinyuk Daria 
Published: September 2021

Abstract
A new bifunctional epoxy resin was synthesized by the reaction of replacing the hydrogen atom of amino groups from 4,4-diaminodiphenylmethane and epichlorohydrin taken in a double excess in dichloroethane. In order to remove HCl formed during the synthesis, which can interact with the initial diamine, as well as with the oxirane rings of both epichlohydrin and the synthesized product, an excess of potassium carbonate was introduced into the reaction mixture. The structure of the synthesized epoxy resin - 4,4′-methylenebis (N- (oxiran-2-ylmethyl) aniline) was characterized and proved by the methods of FTIR spectroscopy, nuclear magnetic resonance and elemental analysis. The kinetic parameters of the synthesized resin were characterized by differential scanning calorimetry. Using the Kissinger method, the activation energy of the self-curing reaction was calculated, the value of which was 1.139 kJ / mol. Such a low activation energy of epoxy resin allows to cure at low temperatures, but shortens the storage time. Two curing modes were studied: 1 mode - 10 hours at 150 ° C, 2 step mode - 10 hours at 150 ° C + 3 hours of postcuring at 180 ° C.

Published: September 2021

Abstract
The physicomechanical and structural characteristics of several elastomers based on terminal epoxy oligomers synthesized from oligotetramethylene oxide diol, various diisocyanates and oligotetramethylene oxide diamine were studied. Additionally, two model compositions of urethane containing elastomers with hard segments were synthesized to reveal the peculiarities of the organization of the supramolecular structure. It was found that the use of 2,4-toluene diisocyanate allows to obtain elastomers with a higher degree of microphase separation and, accordingly, a lower glass transition temperature. It was shown that regardless of the type of diisocyanate used in the synthesis, the elastomer contains crystalline phase. New materials can be used as compounds, adhesives and sealants for various purposes with the possibility of using them under extreme conditions of the Arctic and the Far North.

Published: September 2021

Abstract
This paper proposes a mechanism of gas bubble formation in a down-flowing liquid film as a result of reduced pressure in circulation zones of threaded roughness recesses. Simulation modelling on the Comsol Multiphysics software was used to calculate circulation loops, liquid velocities, and pressure. Thus, the accepted of gas bubble formation was justifying. We experimentally determined gas content along film thickness and its average value, and proposed an equation for calculating gas content along liquid layer thickness. The effect of gas content on the average thickness of a liquid film, as well as its heat and mass transfer, was confirmed.
Exploring sequence transformation in magnetic resonance imaging via deep learning using data from a single asymptomatic patient

Published: September 2021

Abstract
We investigate the potential for deep learning to create a transfer function from T1 to T2 magnetic resonance imaging sequences using data collected from an asymptomatic patient. Neural networks were trained on images of a human left hand, and then applied to convert T1 images to T2 images for the associated right hand. Analysis showed that the most accurate neural network considered the features in the surrounding ∼1 cm when converting to T2, hence indicating that the neural network was able to identify structural correlations between the sequences. However, some small features measuring <2 mm differed, and grid patterning was evident from the images. While using deep learning for sequence transformations could enable faster processing and diagnosis and in turn reduce patient waiting times, additional work, such as synergising physics-based modelling with neural networks, will likely be required to demonstrate that deep learning can be used to accurately create T2 characteristics from T1 images. In addition, since the present work was conducted using data collected from a single patient, further example datasets collected from patients with a range of different pathologies will be required in order to validate the proposed method.

Published: September 2021

Abstract
Clean-energy technologies have been welcomed due to environmental concerns and high fossil-fuel costs. Today, photovoltaic (PV) cells are among the most well-known technologies that are used today to integrate with buildings. Particularly, these cells have attracted the attention of researchers and designers, combined with the windows and facades of buildings, as solar cells that are in a typical window or facade of a building can reduce the demand for urban electricity by generating clean electricity. Among the four generations that have been industrialized in the development of solar cells, the third generation, including dye-sensitized solar cells (DSSCs) and perovskite, is used more in combination with the facades and windows of buildings. Due to the characteristics of these cells, the study of transparency, colour effect and their impact on energy consumption is considerable. Up to now, case studies have highlighted the features mentioned in the building combination. Therefore, this paper aims to provide constructive information about the practical and functional features as well as the limitations of this technology, which can be used as a reference for researchers and designers.
Elevated remnant cholesterol increases the risk of peripheral artery disease, myocardial infarction, and ischaemic stroke: a cohort-based study
Authors: Wadström Benjamin Nilsson , Wulff Anders Berg , Pedersen Kasper Mønsted , Jensen Gorm Boje , Nordestgaard Børge Grønne 
Published: September 2021

Abstract

Aims
The atherogenic potential of cholesterol in triglyceride-rich lipoproteins, also called remnant cholesterol, is being increasingly acknowledged. Elevated remnant cholesterol is associated with increased risk of myocardial infarction and ischaemic stroke. We tested the hypothesis that elevated remnant cholesterol is also associated with increased risk of peripheral artery disease (PAD).

Methods and results
We studied 106 937 individuals from the Copenhagen General Population Study recruited in 2003–15. During up to 15 years of follow-up, 1586 were diagnosed with PAD, 2570 with myocardial infarction, and 2762 with ischaemic stroke. We also studied 13 974 individuals from the Copenhagen City Heart Study recruited in 1976–78. During up to 43 years of follow-up, 1033 were diagnosed with PAD, 2236 with myocardial infarction, and 1976 with ischaemic stroke. Remnant cholesterol was calculated from a standard lipid profile. Diagnoses were from Danish nationwide health registries. In the Copenhagen General Population Study, elevated remnant cholesterol levels were associated with higher risk of PAD, up to a multivariable adjusted hazard ratio (HR) of 4.8 (95% confidence interval 3.1–7.5) for individuals with levels ≥1.5 mmol/L (58 mg/dL) vs. &lt;0.5 mmol/L (19 mg/dL). Corresponding results were 4.2 (2.9–6.1) for myocardial infarction and 1.8 (1.4–2.5) for ischaemic stroke. In the Copenhagen City Heart Study, corresponding HRs were 4.9 (2.9–8.5) for PAD, 2.6 (1.8–3.8) for myocardial infarction, and 2.1 (1.5–3.1) for ischaemic stroke.

Conclusion
Elevated remnant cholesterol is associated with a five-fold increased risk of PAD in the general population, higher than for myocardial infarction and ischaemic stroke.

Abstract

OBJECTIVES
Solitary pulmonary capillary haemangioma (SPCH) is a benign lung tumour that presents as ground-glass nodules on computed tomography (CT) images and mimics lepidic-predominant adenocarcinoma. This study aimed to establish a discriminant model using a radiomic feature analysis to distinguish SPCH from lepidic-predominant adenocarcinoma.

METHODS
In the adenocarcinoma group, all tumours were of the lepidic-predominant subtype with high purity (&gt;70%). A classification model was proposed based on a two-level decision tree and 26 radiomic features extracted from each segmented lesion. For comparison, a baseline model was built with the same 26 features using a support vector machine as the classifier. Both models were assessed by the leave-one-out cross-validation method.

RESULTS
This study included 13 and 49 patients who underwent complete resection for SPCH and adenocarcinoma, respectively. Two sets of features were identified for discrimination between the 2 different histology types. The first set included 2 principal components corresponding to the 2 largest eigenvalues for the root node of the two-level decision tree. The second set comprised 4 selected radiomic features. The area under the receiver operating characteristic curve, accuracy, sensitivity, specificity were 0.954, 91.9%, 92.3% and 91.8% in the proposed classification model, and were 0.805, 85.5%, 61.5% and 91.8% in the baseline model, respectively. The proposed classification model significantly outperformed the baseline model (P &lt; 0.05).

CONCLUSIONS
The proposed model could differentiate the 2 different histology types on CT images, and this may help surgeons to preoperatively discriminate SPCH from adenocarcinoma.

Published: September 2021

AbstractObjectivesNailfold video capillaroscopy (NVC) and angiographic optical coherence tomography (OCTA) have potential in diagnosing PsA and differentiating it from psoriasis vulgaris (PsO) and hand OA. We aimed to assess the diagnostic properties of NVC and OCTA in patients with PsA compared with patients with PsO and hand OA based on nailfold capillary patterns.MethodsPatients with DIP joint PsA and nail involvement (n = 50), PsO with nail involvement (n = 12) and OA (n = 13) were included in this cross-sectional study. Capillaries were evaluated semi-quantitatively and qualitatively. Differences in capillary findings between groups were assessed using mixed linear models. Binary logistic regression analyses were performed to determine the probability for PsA diagnosis based on capillaroscopy findings.ResultsBelow mean capillary density and reduced nailfold blood flow in OCTA images distinguished PsA from both PsO (P = 0.004 and P = 0.052, respectively) and OA (P = 0.024 and P &lt; 0.001, respectively). Qualitative analysis revealed that glomerular capillaries were found in only 3% of PsA patients but in 13% of PsO patients (P = 0.003). Furthermore, crossed vessels were seen in only 55% of PsA patients and 71% of PsO patients (P = 0.043). NVC microhaemorrhage was dominant in PsA patients (13%) and significantly different from OA patients (P &lt;0.05). No capillary pattern was associated with an increased probability of the PsA diagnosis.ConclusionA pathognomonic pattern for PsA diagnosis was not identified; however, we demonstrated some characteristic capillaroscopy findings for PsA, such as decreased capillary density, reduced blood flow and fewer crossed vessels in OCTA and presence of NVC microhaemorrhages.

Mango malformation disease (MMD) caused by Fusarium spp. is an important limiting factor in most production areas worldwide. Fusarium mexicanum and F. pseudocircinatum have been reported as causing MMD in Mexico. These two pathogens also cause a similar disease in Swietenia macrophylla (big-leaf mahogany malformation disease) in central western Mexico, and F. pseudocircinatum was recently reported as causing malformation disease in Tabebuia rosea (rosy trumpet) in the same region. These studies suggest that additional plant species, including weeds, might be hosts of these pathogens. The role that weed hosts might have in the disease cycle is unknown. The objectives of this work were to recover Fusarium isolates from understory vegetation in mango orchards with MMD, identify the Fusarium isolates through DNA sequence data, and determine whether F. mexicanum is capable of inducing disease in the weedy legume Senna uniflora (oneleaf senna). Additional objectives in this work were to compare Fusarium isolates recovered from weeds and mango trees in the same orchards by characterizing their phylogenetic relationships, assessing in vitro production of mycotoxins, and identifying their mating type idiomorph. A total of 59 Fusarium isolates from five species complexes were recovered from apical and lateral buds from four weed species. Two of the species within the F. fujikuroi species complex are known to cause MMD in Mexico. Trichothecene production was detected in five isolates, including F. sulawense and F. irregulare in the F. incarnatum-equiseti species complex and F. boothii in the F. sambucinum species complex. Both mating types were present among mango and weed isolates. This is the first report of herbaceous hosts harboring Fusarium species that cause mango malformation in Mexico. The information provided should prove valuable for further study of the epidemiological role of weeds in MMD and help manage the disease.

Published: September 2021

Purpose of review
To provide an update of the current state of antibody therapy for Severe Acute Respiratory Syndrome Coronavirus 2 infection that has progressed immensely in a very short time period.

Recent findings
Limited clinical effect of classical passive immunotherapy (plasma therapy, hyperimmune immunoglobulin [IgG] preparations) whereas monoclonal antibody therapy, if initiated early in the disease process, shows promising results.

Summary
Although antibody therapy still remains to be fully explored in patients with COVID-19, a combination of IgG monoclonal antibodies against the receptor-binding domain of the spike protein currently appears to provide the best form of antibody therapy, Immunoglobulin A dimers and Immunoglobulin M pentamers also show promising preliminary therapeutic results.
