Published: March 2023

Lead tin telluride solid solutions are excellent candidates for the p-type conduction legs of the thermoelectric generator modules. The investigation of their microstructure properties is an important issue, that can effectively modify their electronic and thermal transport properties. In this work, we show the experimental dependences of the Pb1-xSnxTe component distribution, which were identified as periodic nanostructures with an amplitude of λ ≈ 50-500 nm. The observed periodicity is explained by the generation and recombination of point defects due to diffusion processes during the synthesis, sintering, and annealing of samples. A model describing the formation of such inhomogeneities in Pb1-xSnxTe ternary alloys during isothermal annealing is proposed.

In this study, Mn(x)Zn(1-x)Fe2O4 ferrite samples with x=0.4 and 0.6 were synthesized using a solid-state method and co-precipitation method. In order to determine the effects of various concentrations (x) on the ferrite's structure, particle size, and crystalline phases, prepared samples were analysed using X-ray diffraction (XRD). The XRD patterns revealed that the synthesized samples display a single-phase cubic spinel structure.FTIR analysis showed for both synthesis method have absorption band in the range 400 to 1000 cm-1.SEM analysis shows extreme homogeneity of all the samples. EDX analysis was used to examine for Mn0.4Zn0.6Fe204,The prepared ferrites powders contain Mn, Zn, and Fe, as shown in both synthesis methods.In this approach, alternative synthesis routes for these ferrites are suggested in this study in order to get around some limitations of the traditional preparation method.

Aim. To evaluate the effectiveness of a novel approach to follow-up monitoring of patients with lower extremity peripheral artery disease (PAD) using telemedicine technologies.Material and methods. The study included 175 patients (mean age, 68,1±7,7 years). Two following groups of patients were formed: the main group (n=86), which used an optimized monitoring program using telemedicine techniques, and the control group (n=89), which assumed traditional monitoring by a cardiologist and a vascular surgeon. The mean follow-up period was 11,77±1,5 months. The optimized monitoring program included the implementation of audio communication with patients by an employee with a secondary medical education with an assessment of the current health status according to original unified questionnaire, with the definition of personalized management tactics. At the primary and final stages, the patient underwent an assessment of clinical and anamnestic data, mental and cognitive status, and compliance.Results. At the final stage, uncompensated hypertension was revealed in 36,0% and 49,4% (p=0,0001), smoking — in 30,6% and 42,9% (p=0,05) in the main and control group, respectively. In the main group, a greater pain-free walking distance was revealed — 625,8±395,3 m (control group — 443±417 m (p=0,013)). The average systolic blood pressure was 125,2±10,2 mm Hg and 138,8±15,8 mm Hg (p=0,0001) in the main and control group, respectively. In the control group, a greater number of patients with a high level of personal and situational anxiety were revealed (p=0,05). In the main group, a higher level of adherence to therapy was established at the final study stage (p=0,001).Conclusion. The optimized monitoring program for patients with limited mobility is effective and can be implemented in practical healthcare for patients with lower extremity PAD.

Aim. To analyze Barthel Index of Activities of Daily Living (ADL) in elderly patients with hypertension (HTN) and frailty 6 months after non-ST segment elevation myocardial infarction non-STEMI).Material and methods. ADL was studied in 114 elderly patients (60-74 years old) with non-STEMI, HN and frailty and 80 patients of the same age with non-STEMI and HTN, but without frailty. ADL was determined 6 months after suffering non-STEMI.Results. ADL in patients with frailty was reduced to a greater extent (55,8 [52,4-57,9]) than in non-frail patients (72,9 [70,3-78,6]) (p<0,01). According to factor analysis, ADL reduction in frail patients compared with non-frail patients was mainly due to bed-chair transfer — 6,4 [6,2- 6,8] vs 9,8 [8,1-11,5] (p<0,001), walking test — 8,1 [8,0-8,5] vs 10,6 [9,4-12,7] (p<0,001), stair climbing — 5,3 [5,1-5,7] vs 7,4 [6,8-8,9] (p<0,001). ADL in patients with frailty and blood pressure (BP) <160/100 mm Hg was 62,1 [60,3-69,9], which is significantly higher than in frail patients with BP ≥160/100 mm Hg (48,0 [36,3-53,2]) (p<0,01).Conclusion. In frail patients aged 60-74 years, compared with non- frail patients, 6 months after non-STEMI, ADL was significantly lower in such components as stair climbing, walking, and bed-chair transfer. In patients with frailty and BP <160/100 mm Hg, ADL is significantly higher than in patients with higher blood pressure.

Published: March 2023

The incidence of congenital heart defects (CHDs) reaches 1% of all newborns. Of particular importance is the group of heart defects without a family history and chromosomal disorders, which makes up>80% of all CHDs. These heart defects can be designated as sporadic CHDs, and their etiology and pathogenesis continue to be studied.Aim. To study the association of cytokine and Toll-like receptor (TLR) genes with CHDs in children.Material and methods. We examined 188 children with sporadic (without family history) CHDs (main group) and 103 healthy children without CHDs (control group). Genotyping was performed by real-time polymerase chain reaction (PCR).Results. Sporadic CHDs, in general, and septal CHDs, in particular, are formed on similar intergenic associations that determine the dysregulation of the proliferation and differentiation of progenitor cells of the cardiovascular system. Probably, one of the molecular mechanisms for sporadic septal CHDs may be the inefficiency of intracellular signaling pathways for Nuclear Factor kappa B (NF-κB) due to the primary deficiency of membrane heterodimers TLR1/TLR6, TLR2/TLR6, and TLR1/TLR2.Conclusion. Data on altered proinflammatory potential in the group of sporadic septal CHDs should be taken into account in the postnatal period when conducting cardiac surgery.

Mechanisms of expression, trafficking and biophysical activity regulation of voltage-gated cardiac sodium channels
Authors: Zaytseva A. K. , Kostareva A. A. 
Published: March 2023

Genetic variants in the SCN5A gene, encoding the cardiac isoform of the NaV1.5 voltage-gated sodium channel, were observed in patients with various hereditary heart diseases. Actual problems of modern electrophysiology covers the search for mechanisms of the disease development and the search for approaches to correct sodium current dysfunction in pathological conditions.In recent decades, significant progress has been achieved in understanding the life cycle of NaV1.5 and the distribution of channels in various microdomains of the plasma membrane.NaV1.5 is regulated at all possible levels from SCN5A expression to control of ubiquitin-dependent degradation. Depending on the microdomain of the plasma membrane, NaV1.5 is part of various macromolecular complexes. Thus, in the lateral membrane, NaV1.5 is co-localized with the dystrophin-syntrophin complex, and in the region of the intercalated disc, sodium channels are surrounded by desmosomal proteins, G-ankyrin, and gap junction proteins. This review systematizes knowledge about NaV1.5 protein partners in different regions of the cardiomyocyte membrane, as well as about post-translational modifications of NaV1.5. Special attention is paid to potential clinical applications. Therapy strategies targeting SCN5A synthesis, NaV1.5 transport, and late sodium current are considered. Thus, the study of the mechanisms regulating the functioning of α-NaV1.5 in the future will play an important role not only in understanding the biology and pathophysiology of NaV1.5, but also in the search for new promising methods of therapy.
Intra-arterial regional chemotherapy for pancreatic cancer (review)
Authors: Kaprin D. A. 
Published: March 2023

Pancreatic cancer, despite its low prevalence, is the fourth most common cause of cancer death, with a 5-year survival rate of no more than 10 %. Experts predict that by 2030, pancreatic cancer will become the second most common cause of death from malignant neoplasms, surpassing colorectal and breast cancers. Thus, pancreatic cancer is characterized by very unfavorable prognosis, primarily due to the chemoresistant nature of the tumor.Only a few treatment options for pancreatic cancer are currently available, with low response rates, short progression-free survival and short overall survival, and severe toxicity. In order to improve clinical outcomes, a number of studies on the use of regional chemotherapy as a treatment option for pancreatic cancer have demonstrated dose-dependent tumor sensitivity. Chemotherapy by intra-arterial perfusion of the pancreas made it possible to increase local concentrations of chemotherapeutic agents with minimal effect on healthy tissues and a lower incidence of side effects compared to systemic chemotherapy. This therapeutic approach has demonstrated a good therapeutic effect in the treatment of malignant neoplasms of other localizations. This review summarizes clinical approaches to chemotherapeutic administration by intra-pancreatic intra-arterial perfusion in terms of methods, pharmacokinetics, and clinical outcomes.

Published: March 2023

AbstractGraphite/titanium oxide composite anti-corrosion coating was applied on the surface of aluminum alloy. The surface morphology and composition of the coating were analyzed by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The electrochemical properties of the coatings with different graphite additions were tested by potentiodynamic polarization curves and AC impedance. The coatings with five graphite content were prepared. The phases in the coatings are stable before and after corrosion, avoiding the volume change caused by structural transformation, so that these coatings have good adhesion and are not easy to fall off from the metal surface. As a filler, the graphite dispersed in the coatings extends the penetration path of the corrosive medium. The electrochemical analysis showed that the physical barrier effect of the coating was enhanced with the increase of graphite content, and the optimal addition amount was 2.5%. When the content of graphite exceeds this value, the barrier effect of the coating on the corrosion medium will be weakened due to particle agglomeration.
Fungal plastiphily and its link to generic virulence traits makes environmental microplastics a global health factor

Published: March 2023

Abstract
Fungi comprise significant human pathogens, causing over a billion infections each year. Plastic pollution alters niches of fungi by providing trillions of artificial microhabitats, mostly in the form of microplastics, where pathogens might accumulate, thrive, and evolve. However, interactions between fungi and microplastics in nature are largely unexplored. To address this knowledge gap, we investigated the assembly, architecture, and ecology of mycobiomes in soil (micro)plastispheres near human dwellings in a model- and network-based metagenome study combined with a global-scale meta-analysis. Our results reveal a strong selection of important human pathogens, in an idiosyncratic, otherwise predominantly neutrally assembled plastisphere, which is strongly linked to generic fungal virulence traits. These findings substantiate our niche expansion postulate, demonstrate the emergence of plastiphily among fungal pathogens and imply the existence of a ‘plastisphere virulence school’, underpinning the need to declare microplastics as a factor of global health.
A note on LASSI: a lightweight authenticated key agreement protocol for fog-enabled IoT deployment
Authors: Cao Zhengjun 
Published: March 2023

Abstract
We show that the scheme [Int. J. Inf. Sec., 21(6), 1373-1387] is flawed, in which the user encrypts the temporary ID using a symmetric key encryption in order to achieve the anonymity target. If the shared key for such a symmetric key encryption is really available, the scheme can be greatly simplified. We want to stress that the ultimate use of a key agreement scheme is just to establish a shared key for some symmetric key encryption, but not vise versa.
Assessing water resources systems’ dynamic resilience under hazardous events via a genetic fuzzy rule-based system
Authors: Simic Visnja , Stojkovic Milan , Milivojevic Nikola , Bacanin Nikola 
Published: March 2023

AbstractIn this paper, the use of a novel genetic fuzzy rule-based system (FRBS) is proposed for assessing the resilience of a water resources system to hazards. The proposed software framework generates a set of highly interpretable rules that transparently represent the causal relationships of hazardous events, their timings, and intensities that can lead to the system's failure. This is achieved automatically through an evolutionary learning procedure that is applied to the data acquired from system dynamics (SD) and hazard simulations. The proposed framework for generating an explainable predictive model of water resources system resilience is applied to the Pirot water resources system in the Republic of Serbia. The results indicate that our approach extracted high-level knowledge from the large datasets derived from multi-model simulations. The rule-based knowledge structure facilitates its common-sense interpretation. The presented approach is suitable for identifying scenario components that lead to increased system vulnerability, which are very hard to detect from massive raw data. The fuzzy model also proves to be a satisfying fuzzy classifier, exhibiting precisions of 0.97 and 0.96 in the prediction of low resilience and high rapidity, respectively.
