Authors:   Institute of Mining UB RAS (, Andreeva Liudmila , Abramov2 Sergei ,   Scientific Research Institute of Efficiency and Safety of Mining Production
Published: March 2023

Introduction. The value of resources is becoming increasingly important to mining proprietors, since the maintenance of mining equipment is quite expensive. Increased scope and cost of repairs are largely determined by the quality of mining machines and equipment operation in production environment, as well as by their reliability and maintainability. The costs of preventive maintenance are over the limit by 40–50%, in most instances, due to equipment shutdowns caused by subsystem failures. Components with hidden defects as well as the methods of components reconditioning that do not ensure long-term operation cause a significant overrun of costs for breakdown maintenance. The quality of mining equipment maintenance is in direct relationship with the effective methods of components reconditioning, including the methods of components hardening both during their manufacture at machinebuilding plants and during their repairs at repair works that carry out complex, mainly major repairs of mining equipment. Adherence to the flow process of reconditioning/hardening of the component surface in contact with another component is of great importance. Therefore, to preserve fixed assets, in particular, mining and transport equipment, it is essential to find that reconditioning methods which allow to preserve consumer properties and operability of equipment for a sufficiently long time. Subject matter. The article provides an overview of methods of mining machine components reconditioning/hardening involving concentrated energy fluxes. In the authors’ opinion, these are the most effective methods to increase the resource and reliability of mining machine components by 2–3 times. The choice of components reconditioning/hardening method depends entirely on the service centre capacities, necessary technological equipment availability, personnel qualifications and, most importantly, economic feasibility of using a particular method of reconditioning/hardening. Research objective is to consider the most effective methods of mining machine components reconditioning/hardening. Methods of research include the interpretation of a number of experiments conducted at mining enterprises to obtain comparative characteristics of the most effective methods of mining machine components reconditioning/hardening. Research results. The most effective methods of components reconditioning/hardening are identified and recommended practices are provided. Conclusions. It has been established that the application of a particular components reconditioning/hardening method should be based on the data from tribological maps, as well as necessary equipment availability and economic feasibility.

Research relevance. Studies of the causes and mechanism of hazardous production situations origin and development at coal mining enterprises have shown that their development is most often due to organizational factors, and the prerequisites for their occurrence are associated, to a greater extent, with process flow factors of mining operations, including design decisions. For this reason, it became necessary to establish specific process flow factors that are prerequisites for the emergence of hazardous production situations at a coal pit. Research objective is to establish the factors of hazardous production situations occurrence; to identify and justify indicators of hazardous production situations origin, obtained based on an assessment of the general state of mining, to take into account appropriate scenarios for preventing or avoiding the hazardous production situations in the course of development; to diagnose early signs of their occurrence and eliminate the causes of their development. Methods of research. The state of mining in the coal pit and operations on production safety were assessed from the perspective of hazardous production situations origin and development and was carried out during the process audit. Indicators of the state of the deep pit working area were formed based on the analysis of data from geographic information monitoring of mining, safety rules, as well as process flow diagrams of mining operations. Results. Based on the results of the process audit of the state of mining operations, the factors that are prerequisites for the development of hazardous production situations are determined. They became the basis for the selection of process flow and organizational indicators of hazardous production situations occurrence. The conditions for hazardous production situations occurrence are defined, depending on the presence of objective natural, process flow and organizational factors affecting the safety of work. Conclusions. Open-pit coal mining is naturally accompanied by the emergence and development of hazardous production situations. It is proposed to monitor the prerequisites of hazardous production situations by process flow and organizational indicators in order to make adequate management decisions to prevent the occurrence of hazardous incidents.

Ophthalmic viscoelastic devices (OVDs) are recently used in cataract surgery and have expressivelyupgraded the safety and effectiveness of this surgical procedure. OVDs create and maintain anterior chamber depth and visibility, protecting the corneal endothelium and other intraocular tissues during surgery. The selection of the most adequate OVD is especially relevant when performing cataract surgery in challenging cases, such as in hard, mature cataracts, flat anterior chamber, pseudoexfoliation syndrome, intraoperative floppy iris syndrome, or glaucoma surgery. In such cases, OVD is crucial for facilitating the surgical procedure and the associated minimal complication rate. The use of a combination of OVDs (soft-shell technique and modifications), the use of blue-colored. OVDs, and the combination of sodium hyaluronate with lidocaine have also been described as useful tools in some of these challenging cases.

This study aimed to evaluate the physical attributes of soil in an integrated crop-livestock system with winter pastures managed under different N fertilization timings and canopy heights after winter and the soybean crop. The experimental design used was randomized blocks with the treatments in a 2 × 2 factorial arrangement (two canopy heights and two N application timings), with three area replications. The canopy heights were 11 and 24 cm kept by continuous stocking grazing method since May to November (175 days). Fertilization timings as N-pasture fertilization and N-corn fertilization (phase before the winter pasture). Treatments characterized as N fertilization inversion were applied with fertilization timings as N-pasture fertilization and N-corn fertilization (phase before the winter pasture). Soil density, total porosity, and moisture content were evaluated after winter pasture (black oat + annual ryegrass) and after the subsequent summer soybean crop. The sampling spots were georeferenced and analyzed using geostatistics, considering the position in the slope of landscape. Soil physical attributes were not influenced by canopy height nor N fertilization timing (P>0.05). Soil density was reduced by 13.3% (from 1.11 to 0.98 g cm-3), whereas total porosity (from 0.58 to 0.62%) and moisture content (from 32.73 to 35.73%) increased by 6.9% and 9.2% after the soybean crop in relation to the values obtained in the winter pasture. The higher elevation areas had higher moisture content, total porosity, and lower density than the lower elevation areas, regardless of the time of evaluation. Well-drained soils were more resistant to compaction by animal trampling than moderately drained soils. In well-managed integrated crop-livestock systems in humid subtropical climate regions, the surface compaction of clayey soils in winter pastures is light, non-limiting, and disappears after the subsequent summer crop.

The species Ocimum basilicum has many cultivars with different chemotypes. The basil cultivar ‘Albahaca Dante’ has great economic potential. Nevertheless, there is little data about the production of volatiles and the growth using elicitors. This study aims to evaluate growth, physiological disorders, enzymatic activity, biochemistry, stomatal analysis, and the volatile compounds of Ocimum basilicum L.' Albahaca Dante' cultivated in vitro under different concentrations of zinc sulfate (ZnSO4) and methyl jasmonate (MeJa). The experiment was conducted in a completely randomized design (CRD). Five treatments were evaluated based on the combination of MeJa x Zinc Sulfate, using a Murashige and Skoog medium. The results demonstrate that MeJa reduced the formation of abnormal seedlings. Nevertheless, the growth and the number of leaves were not incremented compared in half without elicitors. The number of volatile compounds was lower in the treatment without elicitors and with 25µM ZnSO4 + 1µMMeja. Methyl chavicol was the main compound in both treatments. In this case, the seedlings had smaller stomata with higher density. The seedlings that were developed under unfavorable conditions (75µM ZnSO4 + 1µM MeJa and 75µM ZnSO4 + 5µM MeJa) produced compounds such as Eugenol, Linalool, Methyleugenol, α-Bergamotene, and showed a reduction in the stomatal density, but larger size. The elicitors influenced the activity of antioxidant enzymes, except for 75µM ZnSO4 + 1µM MeJa, which occasioned an acute decrease of all enzymes. The elicitors altered the volatile composition of this basil cultivar and its biochemical responses

Published: March 2023

Lysosomal acid lipase deficiency is a chronic hereditary degenerative disease, substantially worsening quality of life and leading to lethal outcome. The condition is caused by a mutation of the LIPA gene, that is encoding lysosomal acid lipase, resulting in build-up of cholesterol esters and triglycerides. Clinical-pattern is quite variable: from rapidly worsening lethal infant form and severe infant cases with cirrhosis and liver dysfunction in adolescents to subclinical, mostly asymptomatic forms, manifesting in adults. Thus, major part of patients remains unexamined and the pathology itself undiagnosed, so the real incidence is unclear. This article describes clinical case of the diagnostics of lysosomal acid lipase deficiency in RNO-Alania. Efficiency and safety of enzyme substitution treatment is shown.

Neonatal sepsis is a problem still relevant for healthcare in Russia and worldwide due to high mortality and resistance to treatment. Generalization of infection in newborns occurs because of innate immunity deficiency that particularly leads to neutrophil and monocyte malfunction. Nowadays clinical practice of neonatal sepsis diagnostics does not include phagocytes functional testing. Purpose. The study aims at evaluating the ability of sepsis biomarkers (CRP, PCT, lactate, CD64, CD16, HLA-DR) to differentiate the pathogenesis of organ dysfunction in newborns in the ICU setting.Material and methods. We assessed the surface expression of neutrophil CD64 and CD16, as well as monocytic HLA-DR in newborn ICU patients with different genesis of multiple organ failure — sepsis, asphyxia and combined; as well as different outcomes of hospitalization in the ICU — survivors and deaths.Results. We have shown a significant increase in the neutrophil CD64 expression and a decrease in the monocytic HLA-DR in infectious and combined genesis of multiple organ failure compared with severe asphyxia; deaths were associated with reduced expression of neutrophil CD16.Conclusion. Our data could substantiate combined use of the phagocytes functional testing indicators together with conventional sepsis biomarkers in order to increase their prognostic and predictive value.

Purpose. The study assessed left ventricle longitudinal strain of the endocardial, middle, and epicardial layers in children from one to five years old, born with low, very low, and extremely low body weight.Material and methods. The study was performed in 204 children aged from one to five years; of these, 53 children were prematurely born late in pregnancy, 103 children were born very preterm, and 48 children were born healthy and full-term. The left ventricle longitudinal strain of the endocardial, middle, and epicardial layers was assessed off-line using the Speckle Tracking Imaging-2D Strain technology.Results. Disturbance of the transmural gradient strain of left ventricle wall were detected in 11.32% of prematurely born late in pregnancy children and in 16.5% of very preterm children. A decrease of left ventricle segments strain was registered in 33.96% of children prematurely born late in pregnancy and in 18.44% very preterm children. In children of the same age, born healthy and full-term, transmural wall gradient disturbances and decrease of strain in left ventricle segments were not observed. In children prematurely born late in pregnancy, the disturbance of the transmural strain gradient of left ventricle and the decrease of strain in left ventricle segments are not associated with left ventricle remodeling.Conclusion. The development of the cardiovascular system in children of early and preschool age, born prematurely with low, very low, and extremely low body weight, is characterized by disturbances in the transmural strain gradient of left ventricle wall, due to the processes of postnatal growth and development of the child’s heart, which requires monitoring on an outpatient basis in polyclinic in childhood — by a pediatric cardiologist and a pediatrician, and in adulthood — by a cardiologist and therapist.

The control of urine retention and urination function in children is finally established by the age of 4–5 — it is at this age that the type of urination becomes adult. The stages of the formation of urination function are based on many factors — a decrease in the physiological hypersensitivity of the M-cholinergic receptors of the bladder to acetylcholine, an increase in inhibitory supraspinal effects on the parasympathetic reflex arc, which provides a level of intravesical pressure, on the process of myelination of the brain pathways, on the maturation of the higher cortical center of urination and strengthening of connections with subcortical structures. A tabular assessment of the manifestations of delay and impaired bladder function in children allows us to determine the level of maturity of the system responsible for the urination function. The development of control over the urination is greatly hindered by wearing diapers, failure to provide potty training, and improper water intake schedule in children. The authors of the article identified three age groups of children with enuresis and delayed formation of bladder function and determined at what age which disorders are most relevant. Assessment of the maturity of urination in children with enuresis allows us to analyze the stages of delayed bladder function. In the younger age group (6–7 years), the delay in the formation of self-service skills in the implementation of the act of urination prevailed, including the use of a gender-unreasonable posture. At the age of 8–11 years, there was a predominance of delayed formation of emptying reflexes. At the age of 12–14, there were signs of hypoactivity of the bladder.

The article discusses the main risk factors for the formation of insufficiency and deficiency of vitamin D in children. Particular attention is paid to the course and dietary preferences of the mother during pregnancy, the intake of vitamin and mineral complexes, the nutrition of the child after birth, the type of feeding, the subsidy of vitamin D preparations and complementary foods. 1246 children under four years of age with no history of vitamin D deficiency were examined. With clinical manifestations of rickets, 52 children were identified, who underwent determination of 25(OH) D in serum, while low availability was detected in 21.1%, vitamin D insufficiency — in 63.4% of children, deficiency — in 15.3% of cases. There was an interaction between the use of dairy products enriched with a vitamin-mineral complex containing vitamin D and Ca, the use of therapeutic doses of vitamin D, and an increase in the level of 25 (OH) D in the blood serum.
Yu. V. Knorozov: Studies of Proto-Indian Texts. To the Centenary of the Birth

Published: March 2023

Yu.V. Knorozov is known as a decipherer of the writing of the ancient Maya Indians. But his research included other historical writing systems, including Proto-Indian, much less is known about this. Yu.V. Knorozov began to study it in 1964 and continued with the Group of Ethnic Semiotics he created. Proto-Indian texts have preserved evidence of one of the greatest civilizations of antiquity, which existed in the III–II millennium BC in the northwest of Hindustan, in the valley of the Indus River. In proto-Indian writing, all the difficulties that are possible when studying a forgotten historical writing system were concentrated: neither the letter nor the language, a small number of texts, the absence of bilingualism, etc. are unknown. Nevertheless, in the study of proto-Indian texts, all the tasks necessary in such cases were consistently solved. After a deep analysis of the texts themselves, the type of writing was defined as hieroglyphic (morphemic-syllabic) with all its inherent features. On the basis of formal typological comparisons, it was proved that the language of the Proto-Indian inscriptions was Dravidian; a linguistic interpretation of a number of texts was proposed and a conditional phonetic reading of the signs of proto-Indian writing was established. Yu. V. Knorozov also studied images and symbols accompanying inscriptions on various archaeological sites. The main types of inscriptions were identified, described and analyzed. On this basis, it was possible to reconstruct some features of the religious and mythological ideas of the inhabitants of proto-Indian cities and their calendar and chronological system. The purpose of this article is to show all stages of the study of proto-Indian texts, methodological positions and main results obtained in the course of work under the guidance of Yu. V. Knorozov. The author’s task is to acquaint the scientific community with the significant contribution of Yu. V. Knorozov into work on the study of proto-Indian writing and thereby resurrect one of the facets of the multifaceted image of the great Russian scientist.

Published: March 2023

The article deals with the concepts of charisma and leadership in two non-Western Islamic cultures from the linguistic perspective. The concepts of charisma and charismatic leadership have a long tradition of studying in sociology, political science and psychology since M.Weber. Charisma can be defined as compelling attractiveness or charm that can inspire devotion in others. Cognates of this Greek word are found in most European languages. The English word leader has been borrowed by many related and non-related languages. The questions we are addressing in this article are: How to translate charisma and leader into Bambara and Persian? What Bambara and Persian words can be translated with the English words charisma and leader? What is the origin of these words in Bambara and Persian? How these words function within the two languages and two cultures? To answer these questions we analyze a wide range of lexicographic and textual sources. We come to a conclusion, that in both languages the vocabularies consist of layers of different origin: Soninke and Manding in Bambara, Iranian and Altaic in Persian, Arabic in both languages. Despite long histories of Islamization both languages, though influenced by Arabic, have kept their core vocabularies in what concerns charisma and leadership.
“The Detective World” Magazine and Its Role in the Formation of a Chinese Detective
Authors:   St. Petersburg State University, Mitkina Evgenia I.
Published: March 2023

The beginning of the 20th century in China became the flourishing of literary creativity, at the same time a huge number of translations appeared, among which translations of works in the detective genre were especially popular. Later, many translators began to write detective stories, and that was the mark of the beginning of the Chinese detective’s formation. The publishers could not ignore such a huge interest of readers. At first they published detective stories in newspaper’s pages or appendixes, and then a journal entirely devoted to the works of the detective genre — The Detective World (Zhentan shijie, 侦探 世界) was finally founded in 1923. In the development of the journal, two periods are clearly distinguished: from 1 to 12 and from 13 to 24 issues, this division is associated with a change in the composition of the editorial board and, accordingly, editorial policy. From the 13th issue of the magazine, new headings were opened, contests were held. It housed the works of not only masters of the genre, but also those who had just started to try themselves in the detective genre. Moreover, the magazine began to publish not only works of fiction, but also articles on the theory of the detective genre, in which writers and translators tried to comprehend and systematize this genre. Despite the fact that only 24 issues were published in one year, The Detective World magazine became a noticeable phenomenon in the literary life of the country in the 1920s and an important milestone in the development and popularization of the detective genre in China.

Goal: the purpose of the current paper is to examine how five consumer characteristics (namely, hedonic shopping orientation, comparison shopping proneness, consumer confusion proneness, privacy concerns, and awareness of privacy control) influence the need for different forms of customer experience (CX) individualization. Methodology: the study is based on an online survey of a representative sample of 586 Russian online consumers conducted in mid-2021. Several consumer groups with different preferences for CX individualization are identified using cluster analysis; then multinominal logit modelling is used to define whether five consumer characteristics can predict group membership. Findings: the results empirically confirm that consumers differ in the need for CX individualization and demonstrate that all five consumer characteristics do work in predicting the need for CX individualization, but their role varies for different CX individualization strategies. Originality and contributions: the paper is the first to jointly examine three CX individualization strategies that online retailers may use to interact with customers: content personalization, product customization, and interaction humanization. The results of the study shed light on CX individualization strategies that firms should use to addressthe diverse consumer needs in their long-term strategies.
The Western crescent rises — a verticality dimension in Louisiana’s mixed legal space
Authors:   Loyola University, Puder Markus G.
Published: March 2023

The legal literature discussing mixed jurisdictions has mainly focused on horizontal law mixtures, especially those involving the Civil Law and the Common Law. Harnessing the legal questions raised by land loss in Louisiana’s landscape of waterbodies as a case study, this Article illustrates how American federal law, whether constitutional, statutory or judge-made, has interacted with the allocation of property rights under Louisiana state law. Among the various stakeholders, the legal implications of erosion and subsidence play out in two relationships: firstly, the relationship between private property owners and the State of Louisiana with regard to lakeshore, banks of rivers, bays and streams, and seashore; and secondly, the relationship between the State of Louisiana and the Federal Government with regard to their rights in the territorial sea. In the first relationship, the equal footing doctrine enunciated by the U. S. Supreme Court declares that, because the original thirteen states in the American Union owned the land under their natural navigable water bodies, subsequent entrants would likewise take ownership of such land. Based on the federal equal footing doctrine, Louisiana state law has enjoyed a margin of maneuver to make its own dispositions for the lakeshore, the bank of a river, bayou or stream, and the seashore. Also, when allocating ownership under state law, Louisiana courts have traditionally looked to the federal admiralty definition of navigability. The federal-state interface dominating the second relationship has come to be known as the “tidelands controversy” over submerged lands, along with the wealth of resources, seaward of the low-water mark on Louisiana’s coast. This led to a dance between the U. S. Supreme Court, the U. S. Congress and the State of Louisiana. Although Louisiana ultimately secured jurisdiction up to three nautical miles, its maritime belt still does not match Texas and Florida’s boundaries.

Published: March 2023

Volume capture ratio of annual rainfall (VCRAR) is the key parameter of low-impact development (LID) facilities design, which is significantly affected by the rainfall event division method. However, there is no universal agreement on how to determine an optimal division method to achieve it. A modified minimum inter-event time (MIT) method based on MATLAB software was proposed to find an optimal MIT value. The result showed that the optimal MIT value in Beijing is 200 min based on the daily rainfall data from 1987 to 2016, and the annual average rainfall events were 34.2 with an average rainfall depth of 13.7 mm. Taking bioretention facilities as an example, the errors of design VCRAR under different MIT values were compared based on a Stormwater Management Model (SWMM). The results showed that when design VCRAR was ≤50, 55–60, 60–75, 75–80 and >80%, the optimal MIT value for LID facilities design was 60, 120, 200, 360 and 1,440 min, respectively. Therefore, the optimal MIT should be flexibly selected with the changing of design VCRAR, to ensure that LID facilities meet the design goals.

Published: March 2023

El análisis de redes sociales (ARS) es una herramienta metodológica transdisciplinar ampliamente utilizada para comprender las estructuras de relaciones entre los actores involucrados en la gobernanza territorial de los recursos naturales. Dada la complejidad del conjunto de actores involucrados en la gobernanza territorial del agua que se da a nivel de cuencas hidrográficas, este artículo propone el ARS como una herramienta pertinente para comprender las redes de actores que se configuran alrededor del uso, control y cuidado del agua, integrando actores en diversos niveles sociales, administrativos y territoriales.  Para ello se propone una metodología participativa e incluyente que permite la identificación y reconocimiento de los actores que inciden en el uso del agua, y participan de la gobernanza de la cuenca de manera directa e indirecta. A partir de esta metodología se recopiló información sobre relaciones entre actores del agua, se construyó una matriz relacional y se aplicaron métricas de ARS para analizar la estructura de la red de actores en la Cuenca alta del Río Meléndez- CARM, en Colombia. La metodología permite mostrar los actores del agua como una red hidrosocial, analizar sus características estructurales, identificar los actores más centrales y con diversa participación e importancia en las redes de gobernanza, e identificar los actores que participan del cuidado del agua, y que son claves para mejorar la capacidad de gobernanza y la seguridad hídrica de la CARM.

Background:

Smoking in any form is a significant risk factor for developing cardiovascular diseases, chronic obstructive pulmonary disease, lung cancer, and other oxidative damage-induced diseases. The increasing global trend of E-cigarettes has led traditional smokers to perceive them as a safer option.

Objectives:

This study aimed to compare the levels of malondialdehyde (MDA) as a marker of oxidative damage and high-sensitivity C-reactive protein (hs-CRP) as a marker of inflammation between pure E-cigarette users and tobacco poly-users (smoking combinations of traditional products). Moreover, it also evaluated the influence of Body Mass Index, frequency, and duration of vaping/smoking on these biomarkers.

Materials and Methods:

This analytical cross-sectional pilot study included 40 males aged 18-25 (20 pure E-cigarette users and 20 tobacco poly-users). MDA and hs-CRP were estimated on serum, and SPSS-Version 28.0.1.1 was used for data analysis. Mean hs-CRP and MDA levels for the two groups were compared using the Mann-Whitney-U test.

Results:

Mean level of hs-CRP between the two groups was not significantly different. However, MDA levels were lower in pure E-cigarette users than in tobacco poly-users, especially among those with normal BMI and those who vaped/smoked more frequently and for a longer duration

Conclusion:

Oxidative damage was lesser for pure E-cigarette users and could potentially be the less harmful option than tobacco poly-use. However, E-cigarettes are not the safest substitute for conventional smoking as it causes a similar extent of risk for inflammation-related CVD. Findings need further exploration to study the long-term effects on a larger population group to draw definitive conclusions.
(R)-9bMS Inhibited the Protein Synthesis and Autophagy of Triple
Negative Breast Cancer Cells via Regulating miR-4660/mTOR Axis

Published: March 2023

Background:

Unlike other subtypes of breast cancer, triple negative breast cancer (TNBC)
exhibits aggressive and metastatic behaviors and a lack of effective targeted therapeutics. (R)-9bMS, a
small-molecule inhibitor of the non-receptor tyrosine kinase 2 (TNK2), significantly inhibited TNBC
cell growth; however, the functional mechanism of (R)-9bMS in TNBC remains largely unknown.

Objective:

To explore the functional mechanism of (R)-9bMS in TNBC.

Methods:

Cell proliferation, apoptosis and xenograft tumor growth assays were performed to evaluate
the effects of (R)-9bMS on TNBC. The expression levels of miRNA and protein were detected by RTqPCR
or western blot, respectively. Protein synthesis was determined by analyzing the polysome
profile and 35S-met incorporation.

Results:

(R)-9bMS attenuated TNBC cell proliferation, induced cell apoptosis, and inhibited xenograft
tumor growth. Mechanism study indicated that (R)-9bMS upregulated the expression of miR-4660 in
TNBC cells. The expression of miR-4660 is lower in TNBC samples than that of the non-cancerous
tissues. miR-4660 overexpression inhibited TNBC cell proliferation by targeting the mammalian target
of rapamycin (mTOR), which reduced mTOR abundance in TNBC cells. Consistent with the downregulation
of mTOR, exposure of (R)-9bMS inhibited the phosphorylation of p70S6K and 4E-BP1,
which consequently interrupted the total protein synthesis and autophagy of TNBC cells.

Conclusion:

These findings uncovered the novel working mechanism of (R)-9bMS in TNBC by
attenuating mTOR signaling via up-regulating miR-4660. The potential clinical significance of (R)-
9bMS in TNBC treatment is interesting to explore.
Lithium and Microorganisms: Biological Effects and Mechanisms
Authors: Plotnikov Evgenii , Pukhnyarskaya Dariya , Chernova Anna
Published: March 2023

This review covers the lithium effects on microorganisms, including gut and soil bacteria. Available studies of the biological effects of lithium salts have revealed a wide range of different effects of lithium cations on various microorganisms, but so far, the study of this direction has not been summarized enough. Here we consider the confirmed and various plausible mechanisms of lithium action on microorganisms. Special emphasis is placed on assessing the effect of lithium ions under oxidative stress and adverse environmental conditions. The impact of lithium on the human microbiome is also being reviewed and discussed. Controversial effects of lithium have been shown, including the inhibitory and stimulating effects of lithium on bacterial growth.

Published: March 2023

Objective:

This study aimed to evaluate the possible effects of chlorpyrifos on the rat
hippocampus and evaluate whether these effects can be decreased with chrysin co-administration in an
animal model.

Methods:

Male Wistar rats were randomly divided into 5 groups; Control (C), Chlorpyrifos (CPF),
Chlorpyrifos + Chrysin (12.5mg/kg) (CPF + CH1), Chlorpyrifos + Chrysin (25mg/kg) (CPF + CH2),
Chlorpyrifos + Chrysin (50 mg/kg) (CPF + CH3). After 45 days, hippocampus tissues were evaluated
by biochemical and histopathological tests.

Results:

Biochemical findings indicated that CPF and CPF plus CH administration could not
significantly change SOD activity, and MAD, GSH, and NO levels in the hippocampus tissue of
animals versus controls. Histopathological findings of the toxic effects of CPF on hippocampus tissue
as evidenced by inflammatory cell infiltration, degeneration/necrosis, and mild hyperemia. CH could
ameliorate these histopathological changes in a dose-dependent manner.

Conclusion:

In conclusion, CH was effective against histopathological damage induced by CPF in the
hippocampus through modulating inflammation and apoptosis.
Minimal Contribution of the Social Determinants of Health to the Prevalence
of Hypertension among Egyptian Public Servants
Authors: Eshak Ehab Salah , Kamal Nashwa Nabil , Kamal Nashaat Nabil
Published: March 2023

Background:

Previous research suggests the role of social determinants of health (SDH) in the prevalence of hypertension.

Objective:

The study aimed to estimate the contribution of SDH to the prevalence of hypertension.

Methods:

We recruited 3072 Egyptian public servants who answered a self-administered ques-tionnaire, including hypertension history. We measured the participants’ blood pressure with standardized procedures. The logistic regression models were used to assess the associations be-tween SDH and hypertension

Results:

The prevalence of hypertension was 28.2% (34.2% in males and 22.5% in females). The prevalence of undiagnosed hypertension was 16.3% (23.9% and 9.2%, respectively); thus, 57.8% of the hypertensive subjects were unaware of their high blood pressure status. SDH were associat-ed with the odds of having hypertension in the unadjusted analyses. Higher education, being sin-gle, and having minor family members were associated with low odds of hypertension. On the other hand, non-professional occupations, job hours, household income, total family members, and work-family conflicts were associated with higher odds of hypertension. However, in the multivar-iable analyses, which included all SDH and adjusted for age, gender, smoking, physical activity, body mass index, medical history of chronic diseases, and family history of hypertension, only job hours were associated with the odds of having hypertension and undiagnosed hypertension: odds ratio (95% CI) = 1.07 (1.01-1.14) and 1.11 (1.02-1.20), respectively.

Conclusion:

SDH contributed minimally to the odds of having hypertension among public offi-cials in Minia, Egypt. Civil servants with long working hours should be tracked with regular blood pressure monitoring as a high-risk group for hypertension
