Published: December 2024

Relevance. An increase in the spread of bacteriosis on beetroot in the conditions of the Moscow region carries an epidemiological danger, which actualizes research on the development of a method-ology for evaluating table beet plants for resistance to bacteriosis in the early stages of ontogenesis. The aim of the research. To identify the nature of the relationship between the reaction of sporophyte and microgametophyte to infection with Pseudomonas syringae pv. aptata (Psa) bacterium of beet-root varieties with different resistance of root crops to bacteriosis.Materials and methods. Objects of research: beetroot plants of the Marusya and Krasny Barhat varietal populations, collection strain Psa 1-21. Using phytopathological methods and methods of gamete breeding, plant resistance was assessed in various variants of infection of sporophyte and gametophyte with suspension and culture filtrate of Psa.Results. The average volume of the affected area of the Psa root crops of the Marusya variety was 3.5 times greater than that of the Krasny Barhat variety (Vp = 53 mm3), which is characterized by alignment and absence of susceptible forms (Vp >300 mm3). The Marusya variety has a wide intrapopulation polymorphism in the stability of root crops and leaves, where most genotypes showed medium or high susceptibility to the pathogen. Both varieties showed an increase of 10-30% relative to the control of pollen viability at high (CFU 12*108 cl/ml) and low (CFU 2.4*108 cl/ml) concentrations of the pathogen. The positive effect of Psaon the growth of pollen tubes was noted: in the Marusya variety, as the concentration increased, the stimulating effect increased, in the Krasny Barhat variety, it gradually decreased. When adding a 2.5-fold diluted Psa culture filtrate, the susceptible Marusya variety showed an increase in pollen viability (by 3%), and the resistant Krasny Barhat variety showed a 24% decrease relative to the control. According to the growth rate of the pollen tube, the 4:6 dilution was also differentiating, where the average length of the tubes of the susceptible variety exceeded the control by 10%, and in the stable variety it was 18% lower than the control variant.Conclusion. An inverse relationship was revealed between the resistance of sporophyte to Psa and changes in the functional parameters of the microgametophyte of beetroot varieties Marusya and Krasny Barhat under the influence of a phytopathogen. The results obtained indicate the prospects for the development of a methodology for the selection of bacteriosis-resistant genotypes of beetroot by the reaction of microgametophyte.

Published: December 2024

Relevance. The trend of increasing the area of protected soil and introducing new technologies in the cultivation of vegetable crops of food value can be traced every year. With the development of technology, the requirements for the quality and volume of seed material of hybrids have increased. The main constraints on seed production are the requirements for additional manual labor costs and the complexity of the process, in particular, pollination elements that need to be studied and improved.The aim studying some elements of technology, the optimal time between castration and pollination when crossing fertile tomato lines.Material and Methods. The research was conducted in 2022 year in greenhouse at the Federal State Budgetary Institution "Federal Scientific Vegetable Center". The objects of research were different methods of applying paternal pollen to the stigma of the maternal form. The experiment was carried out between maternal and paternal mid-fruited semi-determinate tomato lines in a hybrid combination. The variants of our experience include time-varying methods of pollen application. Pollination at the same time after castration is a control option, pollination after 4, 12, 24, 48 hours. Options with additional pollination the next day: pollination after 4 (+ after 24 hours), 12 (+ after 24 hours), 24 (+ after 24 hours), 48 hours (+ after 24 hours).Results. In the research, it was found that when pollinated with pollen of the paternal component 24 hours after castration of flowers with additional pollination the next day (24 hours later), the yield of seeds from one fruit on the average fertile maternal line of tomato exceeds 3 times compared with conventional pollination at the same time with castration.
Geoeconomic modelling: southwestern trend of vegetable growing in Russia
Authors: Shabanov T. Yu. 
Published: December 2024

Relevance. Modern globalization, internationalization, regional competitive differentiation actualize geoeconomic modeling methods for geopolitical planning, management and control. The novelty of the proposed solutions is the proposed concept, based on the translation of the ideas of theoretical mechanics into economics.Methodology. Considering the annual values of statistical indicators of territorial concentrates as a system of geographically distributed objects (subjects of the Russian Federation), it is possible to determine the geographic barycenter. Knowing the values of the geocoordinates of the barycenter, it is possible to determine the tendencies and trend of the barycenter movement as an indicator of the dynamics of the system under consideration through the analysis of the dynamics of these coordinates. Based on Russtat data on the annual gross harvest of agricultural crops (vegetables), population by constituent entities of the Russian Federation for the period 1991-2021, data on the coordinates of the administrative centers of the constituent entities of the Russian Federation, the values of the geographic coordinates of the barycenter of vegetable growing in Russia were calculated.Results. For 2021, the geographic coordinates of the barycenter of vegetable growing in Russia are 50.30° N and 49.49° E with an average regional value with an average regional annual vegetable har-vest of 1722.52 million centners/year and fluctuations in the coordinates of the barycenter in the zone of 3-4 geographic degrees or three hundred territorial kilometers with a pronounced south-west trend Analysis of the dynamics of the barycenter for the period 1991-2021. will allow to reveal a slight shift of the vegetable growing barycenter to the south by 3.5 degrees with an increase in the average regional vegetable harvest by 124.11 million centners per year for each degree (or the all-Russian by more than 9,500 million centners per year for each degree to the south), a slight shift of the vegetable growing barycenter to the west by 4.5 degrees with an increase in the average regional vegetable har-vest by 86.5 million centners per year per degree (or the All-Russian by more than 6,660 million cent-ners per year for each degree to the west). For the period 1991-2021, two opposite trends in the devel-opment of vegetable growing are distinguished. In the period from 1991 to 2000, the movement of the coordinate of the vegetable growing barycenter went in the direction of the northeast of Russia, in the period 2000 to 2021 -- on the contrary, to the southwest.The conclusion is made about the existence of a relationship between the development of vegetable growing and the geopolitics of Russia in the period under review. The obtained method and results can be used in strategic state management of agricultural production in Russia.

Comprehensive evaluation of collaborative filtering in drug repurposing
Authors: Réda Clémence , Vie Jill-Jênn , Wolkenhauer Olaf 
Published: December 2024

Abstract

Drug development is known to be a costly and time-consuming process, which is prone to high failure rates. Drug repurposing allows drug discovery to consider reusing approved compounds to mitigate those issues. The outcomes of past clinical trials can be used to predict novel drug-disease associations by leveraging drug- and disease-related similarities. To tackle this classification problem, collaborative filtering with implicit feedback has become popular. It can handle large imbalances between negative and positive known associations and known and unknown associations. However, properly evaluating the improvement over the state of the art is challenging, as there is no consensus approach to compare models. We propose a reproducible methodology for comparing collaborative filtering-based drug repurposing. We illustrate this method by comparing 11 models from the literature on eight diverse drug repurposing datasets. Based on this benchmark, we derive guidelines to ensure a fair and comprehensive evaluation of the performance of those models. Those contributions constitute an essential step towards increased reproducibility and more accessible development of competitive drug repurposing methods.

Published: December 2024

Abstract

Combining ability of enriched Pro-vitamin A yellow maize inbred lines can provide information for breeders to develop biofortified maize hybrids with high yield and desirable traits. Sixty-eight F1 hybrids along with two checks were arranged in alpha lattice design, replicated twice and evaluated across three locations at mid-altitude agro-ecology of Ethiopia. The combined analysis of variance revealed a significant difference (P ≤ 0.01) in mean square due to PVA hybrids, environment and hybrid interaction with environments for grain yield and most of the agronomic traits and it indicates that genotypes performed differently across environments. Seven PVA hybrids were selected based on average yield performance ranging from 7.11 to 7.95 t/ha and 18.69–29.04% yield advantage over the best check and these hybrids should be further evaluated across environments. The mean squares analysis of variance for GCA and SCA showed a significant difference (p ≤ 0.001) for all traits studied, indicating that both additive and non-additive gene effects were important for controlling these traits. Significant positive SCA effect on grain yield was recorded for crosses of L7/L12 (3.16 t/ha), L7/L9 (2.43 t/ha) and L10 x L12 (2.05 t/ha). Only one cross (L9 x L12) displayed significant (p < 0.05) positive standard heterosis (34.52%) over BH 549, whereas non-significant positive heterosis was detected over the BHQPY 545 check. Inbred lines L12, L8, L6, L10, and L2 had the highest positive and significant GCA effects on grain yield and other traits. Out of these lines, L8 and L12 were good combiners for most traits and will be used as alternative testers as they had the highest GCA effect for yield as well as other traits, and also their cross combination were among the top performing hybrids for yield. Our study highlighted that those inbred lines that had a high GCA effect within the heterotic group, could be used as a new source of PVA inbred line development. Furthermore, L8 and L12 can be used as alternative testers for future PVA maize breeding programs.
World Review of Minimally Invasive Approaches for the Treatment of Hydatid Cysts: Laparoscopic, Thoracoscopic, and PAIR
Authors: Vaseghi Sarah , Aslanabadi Saeid , Badebarin Davoud , Farhadi Ebrahim 
Published: December 2024

Abstract

Background: Hydatid cysts, which are caused by the tapeworm Echinococcus Granulosus, present a serious health issue in endemic regions. Traditional open surgery, though effective, often results in substantial morbidity and extended recovery periods. Minimally invasive techniques have been increasingly utilized to mitigate these drawbacks, including laparoscopic, thoracoscopic, and PAIR (Puncture, Aspiration, Injection, and Reaspiration) procedures. This review aims to evaluate the safety, efficacy, and outcomes of these minimally invasive approaches.Methods: A literature search of PubMed and Google Scholar databases was conducted between January 1999 and May 2024. The search included studies related to minimally invasive procedures for treating hydatid cysts of the abdomen, pelvic, and thoracic cavities. Inclusion criteria comprised English-language articles, prospective and retrospective studies, comparative studies, case series, and case reports. Data on demographic details, procedure types, complications, and long-term outcomes were extracted and analyzed.Results: In total, 166 studies involving 3080 patients met the inclusion criteria for the review. Laparoscopic procedures were performed in 1538 cases, PAIR in 1312 cases, and thoracoscopic procedures in 573 cases. The liver was the organ most frequently affected, followed by the lungs, kidneys, and other organs. The use of scolicidal agents was reported in 117 studies, with hypertonic saline being the most frequently used. The mean operating time was 110.16 ± 6.50 minutes, and the mean time of hospital stay was 4.77 ± 0.35 days. Four postoperative mortalities and 291 complications, including biliary leakage, infection, and prolonged air leak were reported. Recurrence was noted in 79 patients, primarily following PAIR procedures.Conclusion: Minimally invasive approaches for hydatid cyst treatment, particularly laparoscopic and thoracoscopic procedures, demonstrate significant benefits such as reduced hospital stays, shorter operation times, and lower complication rates compared to open surgery. However, the higher recurrence rate associated with PAIR necessitates careful patient selection and follow-up. Continued research and clinical trials are essential to optimize these techniques and improve patient outcomes.
Perceived Risk Factors For Diabetes Mellitus Among Civil Servants Of Calabar Municipal Local Government Area, Cross River State, Nigeria
Authors: Sam-Ekpe Vanessa Gedoni , Oyerinde Oyewole 
Published: December 2024

Abstract

Introduction:
The global prevalence of diabetes is rising, posing a major public health challenge. Type 2 diabetes mellitus (T2DM) is a leading cause of morbidity and mortality globally, and civil servants are not left out of this group. One's understanding of the perceived risk factors for developing diabetes influences their decisions on engaging in preventive behaviours.
Methodology:
The study utilised a cross sectional survey design. A multistage sampling technique was used to the respondents based on them meeting the inclusion criteria. A structured questionnaire was administered for data collection. Data was analysed using IBM SPSS version 26.
Results
64.3% of the respondents had high perceived personal risk factors for developing diabetes. 65.9% of the respondents had a high perceived workplace environmental risk factor. 68.2% of the respondents had high perceived psychosocial risk factors. 57.4% of the respondents had high perceived behavioural risk factors and 50.4% of the respondents had low perceived sociocultural risk factors. A significant relationship was reported between perceived workplace environmental, psychosocial, behavioural, and sociocultural risk factors and diabetes.
Conclusion
The relationships between the perceived risk factors and diabetes were statistically significant, but were characterised as weak. This indicates that while these factors play a role, their individual impact may be modest which supports the claim of the multifactorial causation theory which states that diseases are caused by an interplay of different factors. Hence, advocating for policies that address not just one factor but a combination of multiple risk factors is important.

Published: December 2024

Abstract

Separating emulsified oil/water mixture is full of challenges. Special permeable wetted surfaces can separate emulsions but usually require modification by fluorine or silicon based chemicals, which can cause second pollution after use. Carbon aerogels are new chemical free porous hydrophobic materials, which provide a promising approach to selectively adsorb oil from oil water mixture. However, during the course of the fabrication of carbon aerogels, freeze drying is essential, which is time-consuming and energy-intensive process. In this article, we introduced wet papermaking technology manufacturing base paper to replace freeze drying, followed by carbonization in N2 at 800 ºC, hydrophobic carbon paper with a porosity of 90.22% was obtained when the content of micro glass fiber was 70%. The resulting carbon paper not only separates oil slick but also separates emulsified oil/water mixture with an efficiency of 98.5% and flux 1200 L/m2·h.

Published: December 2024

Abstract

The effect of open-pit bauxite mining on beach sediment contamination in the urban coastal environment of Kuantan City, Malaysia, was investigated. The contents of 11 heavy metals (Pb, Cd, Al, Mn, Cu, Zn, Fe, As, Ni, Cr, and Ag) in 30 samples from Kuantan beach sediment zones (supratidal, intertidal, and subtidal) were determined using inductively coupled plasma optical emission spectrometry (ICP-OES) followed by contamination indexes, Pearson’s correlation analysis, and principal component analysis (PCA). The results indicated that Cd, As, Ni, and Ag values in beach sediment zones were significantly higher compared to background values. Contamination indexes suggest that Cd, As, Ni, and Ag were highly contaminated, and moderate to extremely enriched near the Kuantan Port. However, these heavy metal concentrations are lower compared to previous studies in the region. Sediment quality guidelines highlighted the occasional presence of Cd and Ag. Based on Pearson’s correlation analysis and PCA, sources of these heavy metals in beach sediments were likely from agricultural runoff, uncontrolled industrial and residential discharge, and unprotected mine waste near the Kuantan Port. Furthermore, effective management of mining practices and ongoing monitoring are essential to reduce contamination risks.
Energy Consumption Threshold in the Context of Structural Breaks: Evidence from Tunisia Industrial Production Using the Logistic Smooth Transition Regression Approach

Published: December 2024

Abstract

The objective of this paper is to empirically analyze the relationship between energy consumption and economic growth measured by the industrial production index in Tunisia from January 1986 to December 2021. Using the Non-linear Logistic Smooth Transition Model, the results show that there is a non-linear impact. In fact, in the first regime, where optimal energy consumption growth is lower than the threshold of 0.027, energy consumption has a significant and positive impact on economic growth evaluated at 0.715. However, in the second regime, we have found a significant and negative elasticity equal to -0.028, which shows an unfavorable effect on the growth of the industrial production index in Tunisia especially at the threshold level higher than 0.027. Consequently, the relationship between Tunisia's energy consumption and growth is not stable.
