Umbilical cord mesenchymal stem cells from gestational diabetes show impaired ability to up-regulate paracellular permeability from sub-endothelial niche
Authors: Salem Samar , Leach Lopa
Published: January 2024

In vitro studies have shown that Wharton’s jelly mesenchymal stem cells (WJ-MSCs) can cross umbilical and uterine endothelial barriers and up-regulate endothelial junctional integrity from sub-endothelial niches. This pericytic behaviour may be lost in pregnancies complicated by gestational diabetes (GDM), where increased vascular permeability and junctional disruption are reported. The aim of the present study was to investigate whether WJ-MSCs isolated from GDM pregnancies displayed any changes in morphology, proliferation, VEGF-A secretion, and their ability to influence paracellular junctional composition and permeability. WJ-MSCs were isolated from human umbilical cords from normal pregnancies (nWJ-MSCs, n=13) and those complicated by GDM (gWJ-MSCs), either diet-controlled (d-GDM, n=13) or metformin-treated (m-GDM, n=9). We recorded that 4-fold more WJ-MSCs migrated from m-GDM, and 2.5-fold from d-GDM cord samples compared with the normal pregnancy. gWJ-MSCs showed a less predominance of spindle-shaped morphology and secreted 3.8-fold more VEGF-A compared with nWJ-MSCs. The number of cells expressing CD105 (Endoglin) was higher in gWJ-MSCs compared with nWJ-MSCs (17%) at P-2. The tracer leakage after 24 h across the HUVEC + gWJ-MSCs bilayer was 22.13% and 11.2% higher in the m-GDM and d-GDM, respectively, HUVEC + nWJ-MSCs. Transfection studies with siRNAs that target Endoglin were performed in n-WJ-MSCs; transfected cells were co-cultured with HUVEC followed by permeability studies and VE-cadherin analyses. Loss of Endoglin also led to increased VEGF-A secretion, increased permeability and affected endothelial stabilization. These results reinforce the pericytic role of nWJ-MSCs to promote vascular repair and the deficient ability of gWJ-MSCs to maintain endothelial barrier integrity.
An analytical formula for back EMF waveform of a counter‐rotating dual‐rotor non‐slotted axial flux permanent magnet synchronous machine
Authors: Mirzahosseini Reza , Rahimi Namaghi Elham
Published: January 2024

Fractional slot concentrated winding (FSCW) permanent magnet (PM) machines are gaining more attention for low‐speed applications because of their great advantages. This paper proposes a new structure for an FSCW double rotor axial flux PM synchronous machine (DRAFPMSM) with counter‐rotating rotors. In addition, an analytical formula for the Back EMF waveform of the proposed structure is presented. The accuracy of the formula is investigated by designing a 40 W sample machine. The rotors of this machine rotate with speeds of 600 and 428 rpm in opposite directions. The Back EMF of the sample machine is calculated using the suggested formula. In addition, the finite element method (FEM) is used to determine the Back EMF waveform. Comparison of the obtained results confirms that the new formula yields the Back EMF precisely such that the results well match to those of FEM. The effect of the relative position of two rotors on the Back EMF waveform is investigated using the proposed formula. In addition, the optimum relative position of two rotors for minimizing the Back EMF THD of the case study machine is determined.
Safety analysis of autonomous vehicles based on target detection error
Authors: Rong Donglei , Jin Sheng , Liu Bokun , Yao Wenbin
Published: January 2024

Connected and automated vehicles (CAVs) rely on their perception systems to detect traffic objects, with the uncertainty in detection results significantly influencing the safety of their decision‐making and control mechanisms. This paper introduces a safety potential field for CAVs that accounts for target detection errors. Initially, the paper categorizes errors arising from target detection into classification, labelling, and positioning categories. Subsequently, an elliptical model‐based safety potential field is developed, incorporating potential field line optimization using safety thresholds and lane lines. This approach facilitates the determination of critical values and safety distribution for the potential field. The paper then proceeds with coefficient calibration and experimental analysis to validate the reliability of the proposed model. Findings indicate that as target detection errors increasingly manifest, the safety potential field area for CAVs becomes more restrictive, enhancing the field's sensitivity to these errors. The critical safety value for CAVs is maintained within the range of [0 m, 7 m], providing a stable basis for decision‐making and control. Additionally, the safety value for CAVs falls between [15, 25], favouring the improvement of safety gradient distribution under the calibrated safety potential field values.

Published: January 2024

The main task of agriculture is to increase the productivity of cultivated plants, and therefore the development of methods that regulate the growth and development of agricultural crops is becoming increasingly important. It is known that plant development in response to external stimuli is regulated by peptide phytohormones. In addition, peptides are considered as antimicrobial agents. The review examines peptides of the CLE, EPF, PSY, PSK, RGF, CIF families, dipeptide KE, tripeptide EDR and tetrapeptides AEDL, KEDG, AEDR, KEDP and their role in the regulation of plant differentiation and growth. The wide range of biological activity of peptides allows us to propose their use to increase the productivity of new generation plants.

Authors: Zaitsev S.Yu. , Sotnikova L.F. , Stepanova M.V. , Melikova Y.N. , Belopukhov S.L.
Published: January 2024

There are numerous biochemical and physical methods for agrobio- and nanomedical sciences. The real-time interfacial tension (RTIT) of various liquids is a powerful analytical method. The main aims of the present work are the following: to study the parameters of the RTIT of the mixtures based on some proteins, lipids, salts as the model systems for animal blood diagnostics. The greatest differences in the RTIT values observed at different concentrations for the aqueous dispersions: albumin: lipid: salt “at the short time of existence of the surface”. The high salt concentrations have some particular effects on RTIT values for these mixtures at all times. The changes in albumin concentration influence all RTIT values, but the changes in lipid concentration have insignificant influence and only “at the long time of existence of the surface”. Such data have high importance both for fundamental studies and for possible applications in animal and human medicine.
Lightweight Federated Transfer Learning for Plant Leaf Disease Detection and Classification across Multiclient Cross-Silo Datasets
Authors: Choubey Shilpi , Divya
Published: January 2024

Plant leaves and crops play a crucial role as a primary food source globally, making significant contributions to dietary iron intake (9%) and energy consumption (23%) per capita in the Asian region. Bacterial, yeast, and other microbial diseases pose significant challenges to farmers as they detrimentally impact plant health and reduce crop productivity. The manual diagnosis of these diseases poses a considerable challenge, particularly in regions with a scarcity of professionals specializing in leaves and crop protection. Automating leaf disease detection and providing easily accessible decision-support resources are crucial for facilitating efficient leaf protection strategies and mitigating crop damage. Despite multiple classification methods for diagnosing leaf diseases, a secure and accurate approach that fulfills these requirements has not yet been identified. This paper presents an architectural framework called Lightweight Federated Transfer Learning (LFTL) that addresses the challenge of Leaf Disease Detection and Classification (LDDC) while ensuring data privacy limitations are upheld. A dataset consisting of leaf disease images has been compiled, characterized by an imbalance in the distribution of the diseases. The collection includes four conditions: bacterial decay, brown spot, blast, and tungro, corresponding image counts of 1695, 1551, 1711, and 1419, respectively. Following the preprocessing stage, the LFTL framework was tested using both Independent and Identically Distributed (IID) and non-IID datasets. The study commenced with an efficacy evaluation of the Convolutional Neural Network (CNN) and eight TL models in the LDDC. The framework’s performance was evaluated across different circumstances and compared to conventional and federated learning models. The study’s findings revealed that the LFTL framework outperformed traditional distributed deep-learning classifiers, thus demonstrating its efficacy in individual and multiple client scenarios.

Published: January 2024

The article demonstrates the possibility of applying intelligent digital technologies to forecast the development of net blotch disease in winter barley caused byPyrenophora teres. The obtained intelligent solution in the form of a binary decision tree has the ability to determine scenarios of net blotch development into three classes: depressive, moderate, and epiphytotic. To effectively train the model during the period from 2021 to 2023, field and laboratory experiments were conducted on the research sites of the Federal Research Center of Biological Plant Protection. The experiments collected data on the degree of leaf damage, the type of resistance of the variety, the growth phase at which primary infection occurred, and the average relative air humidity during the vegetation period in which infection occurred. The total sample size was 249 observations. The trained model demonstrated high classification accuracy on both the training and test sets, with an accuracy rate exceeding 0.96 and 0.92, respectively. The study shows that the innovative method discussed in the article for forecasting the development of net blotch in winter barley can be successfully integrated into the overall strategy of phytosanitary diagnostics of grain crops, including barley.

Published: January 2024

Transition medicine aims at the coordinated transfer of young patients with a
chronic disease from paediatric to adult care. The present study reflects 20
years of experience in transitioning patients with congenital adrenal
hyperplasia (CAH) in a single center setting. Our endocrine transition-clinic
was established in 2002 and offers joint paediatric and adult consultations.
Data were evaluated retrospectively from 2002 to 2005 and 2008 to present.
Fifty-nine patients (29 males) were transferred. Median age was 18.4 years
(17.6–23.6). Ninety percent of the patients presented with
21-hydroxlase-deficiency (21-OHD), 38 patients (23 m) with salt-wasting
(sw), 7 (1 m) with simple-virilising (sv) and 8 (3 m) with the
non-classic (nc) form. Rarer enzyme deficiencies were found in 6 cases:
17α-OHD (2 sisters), P450-oxidoreductase-deficiency (2 siblings),
3β-hydroxysteroid-dehydrogenase-deficiency (1 m) and
11β-OHD (1 female). Thirty-four patients (57.6%, 20 m)
are presently still attending the adult clinic, 1 patient (1.7%, m)
moved away and 24 (40.7%, 8 m) were lost to follow-up (13
sw-21-OHD, 6 sv-21-OHD, 5 nc-21-OHD). Thirty-seven patients (62.7%)
attended the adult clinic for >2 years after transfer, 17
(28.8%) for >10 years. In the lost to follow-up group, median
time of attendance was 16.3 months (0–195.2). Defining a successful
transfer as two or more visits in the adult department after initial
consultation in the transition clinic, transfer was efficient in 84.7%
of the cases. A seamless transfer to adult care is essential for adolescents
with CAH. It requires a continuous joint support during the transition period,
remains challenging, and necessitates adequate funding.
Statement of the Obstetrics and Prenatal Medicine Working Group (AGG – Preterm Birth Section) on “Outpatient Management for Pregnant Women with Preterm Premature Rupture of Membranes (PPROM)”
Authors: Kunze Mirjam , Maul Holger , Kyvernitakis Ioannis , Stelzl Patrick , Rath Werner , Berger Richard
Published: January 2024

Preterm premature rupture of membranes (PPROM) is one of the leading causes of perinatal morbidity and mortality. After a PPROM, more than 50% of pregnant women are delivered within 7 days.
Fetal and maternal risks are primarily due to infection and inflammation, placental abruption, umbilical cord complications and preterm birth.

Standard care usually consists of an expectant approach. Management includes the administration of antenatal steroids and antibiotic therapy. Patients with PPROM require close
monitoring.

The management of pregnant women with PPROM (inpatient vs. outpatient) is still the subject of controversial debate. The international guidelines also do not offer a clear stance. The
statement presented here discusses the current state of knowledge.

Dear colleagues,

When younger fellows ask for guidance on how to choose a research project, many
aspects require consideration: how to select a supervisor and mentor, should one
change the institution, how does the project boost the later professional career,
what are personal and professional aims. As many can probably relate it is passion
for the research topic, both by the fellow and the mentor, that will go a long way
and most often result in successful project completion.
Beyond right and wrong: on the conditionality of dirty hands
Authors: Malkopoulou Anthoula , Dhar Siddhartha Kumar
Published: January 2024

Dirty Hands theorists disagree about how agents should resolve a high-cost moral dilemma, but their disagreement is partly because they tend to discuss widely different cases of a broad and heterogeneous phenomenon. Moralists are typically concerned with problems that often involve an agent who is under coercion and is asked to engage in an activity that will cause severe and certain harm to individuals. Realists, on the other hand, base their observations on cases where political parties negotiate to form coalitions or policy platforms; these compromises may affect the political integrity and representative credibility of the agent, but less so their moral integrity as measured by universal moral standards. Yet, both types of Dirty Hand scenarios concern the same phenomenon: an urgency to make a morally costly compromise. As a result, we propose to evaluate Dirty Hands problems by placing them on a dual continuum based on two conditions: their projected outcomes, and their external circumstances. We propose that the position of a moral problem on this continuum affects the extent to which a compromise is or is not excusable. Finally, we consider the implications of our findings for the Dirty Hands debate and for the study of political ethics more broadly.
Impacts of border closure policy on entrepreneurial activities in selected main markets in Ibadan, Southwest, Nigeria

Entrepreneurial activities are fast becoming the primary means of livelihood as an increasing number of people are embracing it to overcome socio-economic challenges. However, many in certain sectors of the entrepreneurial activities are faced with many policy challenges. This study seeks to find out the lived experiences of the retailers involved in entrepreneurial activities related to the border closure and the effect of the policy on entrepreneurs’ businesses as it influences the informal sector in the Ibadan metropolis. The study adopts the Mertons’ Functionalist theory to situate study concepts. The descriptive research design with the use of qualitative methodology was adopted for the study. The in-depth interview was conducted with 10 entrepreneurs in the Ibadan metropolis and analysed in themes in line with the study objectives. This is adjudged sufficient for a qualitative study and many of the responses were almost similar. Study findings show that there have been more complaints about their activities since the border closure policy was enacted. That is, the state of entrepreneurial activities has been deteriorating since the implementation of the policy. However, irrespective of the challenges, the study reveals that the entrepreneurs still make their profit, even though at a reduced rate. Based on the findings, it was recommended that entrepreneurs be educated and sensitised on the impact and usefulness of any government decision on the business environment to prevent opposition within the society. In addition, the porosity of the border (land border) and not the closure of the wall should be of much concern to the government and their officials; hence, the government should tighten up the borders by having strict regulations when it comes to trading, importation and exportation of commodities across borders.
