A field investigation entitled “Effect of different weed management practices on growth, yield and weed dynamics of summer sesame (Sesamum indicum L.)” was under taken during summer seasons of 2020 and 2021 at agricultural farm of Krishi Vigyan Kendra, Pahanda (A), Durg (Chhattisgarh). The experiment was laid out in Randomized Block Design (RBD) with three replications. The treatments comprised W1: Weedy check, W2: Hand weeding at 20 and 40 DAS, W3: Pendimethaline 30 EC @ 1 kg ai ha-1 as PE, W4: Quizalofop ethyl 5 EC @ 40 g ai ha-1 at 20 DAS, W5: Propaquizafop 10 EC @ 50-100 g ai ha-1 at 20 DAS, W6: Imazethapyr 10 SL @ 75 g ai ha-1 at 25 DAS and W7: Weed free check. The highest seed yield (752.00 and 830 kg ha-1) was recorded in W7; Weed free check, which was at par with W2; hand weeding at 20 and 40 DAS (721.33 kg ha-1 in 2020 and 800.00 kg ha-1 in 2021), followed by W5; propaquizaofop (662.00 kg ha-1 in 2020 and 758.33 kg ha-1 in 2021) and W4; quizalofop ethyl (640.33 kg ha-1 in 2020 and 733.67 kg ha-1 in 2021), while the lowest seed yield was achieved by W1; weedy check (268.00 kg ha-1 in 2020 and 366.67 kg ha-1 in 2021).This treatment also recording highest values on yield parameters. Among the different weed management treatments, weed free check (W7) recorded statistically lower density of total weeds (2.27, 2.26, 2.62 m-2 during 2020 and 2.69, 2.69, 2.83 m-2 during 2021) than rest of the treatments at 45, 60 and 75 DAS. Second best treatment was W2; two hand weedings at 20 and 40 DAS. Among all the herbicidal treatments, application of propaquizafop recorded lower density of total weeds (5.64, 5.56, 5.64 m-2 during 2020 and 5.37, 5.58, 5.71 m-2 during 2021).

Background: An individual's health is largely determined by nutrition, and nutrition is determined by diet, which consists of a variety of food items. As a result, eating a well-balanced and healthy diet is the single most significant element in achieving and maintaining good. The health of an individual depends to a large extent on nutrition and nutrition depends on diet, which consists of various articles of food. Hence balanced and nutritious food is the most important single factor in connection with the attainment and maintenance of health. Objective: 1) To study Nutritional deficiency disorders among the tribal population. 2) To study the composite nutritional value as per the given Weightage. 3) To examine the pattern of diet and nutrition and their availability and intake in study regions. Methods: Statistical and cartographic techniques have been used for the research work to precise conclusions. Per head per day availability foodstuff stuffs like, cereals, pulses, milk, vegetables etc. has been finding out and shown through PHC wise isopleths maps. PPHC-whisper head per day consumption has been calculated through the sample village survey. A total of 115 villages are chosen, and 23 villages from the list of ITDP villages have randomly chosen in each tehsil. By using a probability proportional to the size of the various tribes, a total of 10 households (HHs) from each chosen village have been covered. Result: The cumulative nutritional values of cereals are derived from the total of all weight ages measured so far. The composite nutrient values for cereals were 14.72 in Peint tehsil. This method was used to quantify the composite nutrient value for pulses, edible oil, milk, vegetables, and fruits. The cumulative composite value of Peint tehsil was 67.22 when the composite nutrition values were added together. The table shows the cumulative composite nutrition values measured on a tehsil-by-tehsil basis. Conclusion: The indigenous inhabitants of the study region eat jowar, maize, wheat, and bajara as their major foods. Despite the fact that the terrain is conducive to rice farming, they still consume rice on occasion. Pulses are a staple of indigenous people's diets, which they consume on a daily basis. However, they consume very little fat-containing foods such as oil and milk in their regular diet. Similarly, just a small percentage of households include fruits and vegetables in their daily diet. These people are unable to acquire such expensive items due to their poverty. The general nutritional status is measured by computing composite nutrition values. For the entire region, the average composite nutrition value is 74.81.

Bio degradation of organic waste such as agricultural waste is the most important and efficient way to remove these compounds from the environment. Bacteria, actinomycetes, fungi, algae and protozoa are the main microorganisms found in soil that decompose soil organic materials, of which bacteria are the most prominent and abundant. Microbes use these waste compounds for their own metabolism and produces some simple and useful compounds, important for soil health, plant growth and overall ecological balance. Microorganisms have the ability to chemically and physically interact with substances, leading to structural changes or complete degradation of target molecules. Therefore, this study was focused on the importance of isolation, characterization and identification of bacteria from farm waste and its application on farm waste for the production of compost. In this study the various bacteria from farm waste were isolated in the department of Microbial and environmental biotechnology at MGM College of Agricultural biotechnology, Gandheli, Aurangabad, Maharashtra. The bacteria were assessed by using various morphological biochemical and genetic characterization. The bio culture prepared from the isolated bacteria was applied for the degradation of farm compost. It was found that the bioculture degrade the compost in twenty one days with all the standard characters of compost. It was assessed by using detection tests. Thus by using the bio culture the farm waste decomposition can be carried out. With further molecular studied the exact species of the bacteria can be identified and used as a formulation for compost decomposition.

The rhizosphere soil is a source for a diversity of microorganisms which play a vital role in the enhancement of plant health through the mechanism of symbiotic interaction thereby influencing the plant growth. The present study aimed at isolating potential phosphate solubilizing rhizobacteria from pea (pisum sativa) crop for which, rhizosphere soil samples were collected from two pea growing districts of Kashmir valley viz. Srinagar and Baramulla. Isolates were cultured on nutrient agar medium followed by serial dilutions and different colonies with morphological variations were isolated from each dilution. A total of 80 bacteria were isolated and maintained as pure cultures. Out of the 80 isolates, 25 strains showed phosphate solubilizing ability and amongst them, 9 were highly potential which were subjected to morphological and biochemical characterization. Furthermore, the potential bacteria were analysed for Indole Acetic Acid (IAA) production, which was found to be directly proportional to the plant growth promotion. After screening the best nine isolates PGP1, PGP10, PGP28, PGP40, PGP49, PGP52, PGP60, PGP72 and PGP75 were selected for their effect on growth and yield in field conditions using pea as test crop.

Infections caused by ESBLs-producing E. coli continue to represent a challenge for the implementation of appropriate treatment protocols worldwide. The objective of the present study was to assess the current profile of antimicrobial and ESBLs susceptibility, to screen the bla-CTX-M, bla-TEM, bla-SHV and qnrs genotypes of ESBLs-producing or non-isolated ESBLs-producing Multi-resistant E. coli (MDR) strains of various clinical samples in Chad. This is a prospective study conducted from September 2018 to February 2019 at the N’Djamena University Hospital in Chad. E. coli MDR has been isolated from urine, pus and stool cultures. Antibiotic identification and susceptibility testing was performed using an automated system, the Vitek-2. Confirmation for ESBLs production was performed by the double disc synergy assay. The E.coli MDR and ESBLs strains, positive or not, were screened for the genes encoding the ESBLs and qnrs by PCR. Microsoft Excel 2016 and SPSS ™ statistical software version 20.0 were used for the analysis of the results. Of the 68 MDR E. coli isolated from various clinical samples, 40 (58.8%) were positive for extended spectrum beta-lactamase production. 47.1% were resistant to the twelve (12) antibiotics tested. All isolates with an ESBLs phenotype were resistant to at least one antibiotic tested. The CTX-M gene was in the majority (72.1%), followed by TEM (54.4%) and SHV (16.2%). The qnrs genes were also detected in 52.9% (qnrA1 to A6), 52.9% (qnrB1 to B6) and 2.9% (qnrS1 to S6). All strains showing an ESBLs phenotype (40) were also positive in the molecular screening of ESBLs gene families. A double and triple carriage of the ESBLs and qnrs genes was observed. These results show the need for an aggressive infection control program, systematic detection of ESBLs isolates in clinical samples and antimicrobial management in hospitals in Chad.

Moringa oleifera, traditionally consumed in some countries, is now widely distributed throughout the tropics, particularly in Africa. It is consumed in the form of food supplements in Côte d'Ivoire. However, the production method of Moringa leaf powder could be a source of contamination by potentially mycotoxigenic moulds. The objective of this work was to evaluate the level of contamination of Moringa powder by Aspergillus Spp strains and to detect the genes involved in the biosynthesis of aflatoxin B1. A total of 288 samples of Moringa powder were collected from vendors in six communes of Abidjan district. Isolation and purification of Aspergillus isolates were performed on Sabouraud medium with chloramphenicol. The identification of these strains was carried out by macroscopic and microscopic observations. The molecular aspect of the Aspergillus species and the detection of the Nor, Ver, AvfA and AflR1 genes, involved in the biosynthesis process of aflatoxin B1, were carried out by PCR. The results show that the contamination rate of Moringa powder by Aspergillus spp was 62.46% with a predominance of Aspergillus niger (33.16%). Other species namely Aspergillus flavus (27.07%), Aspergillus fumigatus (24.87%) and Aspergillus terreus (13.98%) were also observed. The prevalences of strains harbouring the AflR1, Nor, Ver, and AvfA genes were 70.47%, 73.07%, 52.85% and 41.97% respectively. Strains harbouring AflR, Nor, Ver, and AvfA genes simultaneously were also detected in proportions of 39.37%. The presence of Aspergillus harbouring the genes coding for Aflatoxin B1 biosynthesis in Moringa powder could constitute a health risk for the consumer.

Published: June 2023

Sputum examination is a simple and rapid diagnostic tool for the presumptive identification of pathogens. It is one of the oldest and most entrenched technique still in use.Identification of fastidious organisms is important in diagnosis of infections which causes serious diseases whose detection and monitoring is crucial in treating many cases. Direct gram staining places a very important role in identifying these fastidious organisms like Streptococcus pneumoniae, Haemophilus influenzae, Legionellae which may not grow in routine bacterial cultures. Correlation between direct gram staining and sputum cultures helps us to identify these fastidious organism which is crucial for initiation of treatment. This is a descriptive study conducted in the bronchitis patients admitted in the medical ward of GMKMCH, Salem for 3 month period from August, 2022 to November, 2022. 216 sputum samples collected and direct smear and bacterial culture done for the detection of fastidious organisms. 216 sputum samples were collected and direct smear by gram staining done. By bartletts scoring 182 samples were included. Out of 182 samples76 stained smear showed Gram positive cocci in 23 smears and Gram negative bacilli in 49 smears. Out of 123 plated samples, GPC isolated was 21,GNB isolated was 90 and Candida spp was 12. Only 3 Streptococccus pneumoniae were isolated. In the present study, good quality sputum samples was obtained in 182 (85%) of 216 patients, which is a higher yield than reported in previous studies. An additional benefit of sputum Gram stain is that it can validate the subsequent sputum culture results. The growth of an organism from a sputum sample does not always indicate the presence of infection. Results of sputum culture can yield false positive findings related to colonization or contamination, and thus should be utilized with the results of the sputum Gram stain when establishing the definitive etiologic diagnosis of pneumonia. Vancomycin is the highest sensitive drug with 100% sensitivity.33% of the isolates are sensitive to penicillin and 66% are resistant. sensitivity to Tetracyclines are 33% and only 33% of the isolates are sensitive to Erythromycin.66% of the isolates are sensitive for Oflxacin and least sensitivity is observed for Cotrimoxazole.

Skin being the largest organ of our human body and Out of numerable immune preclusion mechanisms in our body skin is one of the momentous defence. For those patients who survive initial burn injury infection is an imperative issue. Burn wound injuries are one of the most common, invasive and devastating forms of trauma. Despite the recent advances in burn wound management, bacterial infections persist as an important complication and leading cause of morbidity and mortality among burnt patients. The leading issue in burns wound management is culpability of the burn wound to colonisation of bacteria. Disparity of bacterial flora isolated is appreciated during the period of wound healing. This descriptive study was performed in the department of Microbiology, in conjunction with the burns wards in a Tertiary care hospital. This study was conducted from 2022 October to 2022 December. Organisms are identified based on the morphology of the colonies, Gram stain appearance, testing for presence of catalase enzyme, testing for presence of oxidase enzyme, testing of motility by hanging drop method. Antibiotic susceptibility test was done using modified Kirby Bauer’s disc diffusion method on Mueller Hinton Agar as per Clinical and Laboratory Standards Institute Guidelines. Out of 100 patients, majority of them belongs to 21-40 years and female patients were 61%. Out of 100 samples processed, 67 sample showed bacterial growth and 43 sample showed no growth. Among the 67 sample with growth, gram negative isolates (68.6%) were more compared to gram positive isolates(31.3%). Klebsiella species (26.8%) were the most predominant organism isolated followed by Pseudomonas aeruginosa (16.4%), Proteus species (11.9%), Acinetobacter baumannii (8.9%), Escherichia coli (4.4%) among gram negative organisms. In the gram positive isolates, Staphylococcus aureus were (16.4%), followed by Coagulase negative Staphylococcus (10.4%), Enterococcus species (4.4%). Klebsiella is the most common isolate among all followed by Pseudomonas, Staphylococcus aureus. Piperacillin and tazobactam, carbapenem has increased sensitivity when compared to other drugs for Gram negative pathogens, where as Cotrimoxazole, Amoxycillin Clavulanic acid, Ciprofloxacin all have very high resistance.

Pyogenic infection refers to an infection that produces pus and is usually characterized by multiple focal inflammations due to microbial growth. The incidence of wound infection varies depending on various factors such as wound condition, microbial load and host defense mechanisms. The predominant wound pathogens are Gram negative bacilli such as Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Enterobacter spp., Proteus spp.& Gram positive cocci such as Staphylococcus aureus, Coagulase negative Staphylococcus, Streptococcus spp., Enterococcus spp. and anaerobic bacteria such as Bacteroides, Clostridial spp. Klebsiella species acquired resistance to many antibiotic classes including β -lactams, fluoroquinolones, aminoglycosides by different mechanisms results in multidrug resistant strains. This study was performed in the department of Microbiology, in conjunction with the Surgery and Ortho department in a Tertiary care hospital. Microorganisms were identified by using standard methods. Antibiotic susceptibility test was done using modified Kirby Bauer’s disc diffusion method on Mueller Hinton Agar as per Clinical and Laboratory Standards Institute Guidelines. Phenotypic identification is done by Combined Disc Test, Double Disc Synergy Test, Modified carbapenem inactivation method (mCIM), EDTA- modified carbapenem inactivation method (eCIM), RapidecCarba NP test. Among those samples 306 organisms showed growth, which are identified and tested for antibiotic susceptibility testing. Among them 128 Klebsiella species isolates are grown & from those 11 klebsiella isolates showed resistance to Carbapenems and their Carbapenemase production is detected by a set of screening and confirmatory tests. Klebsiella spp. has been isolated in higher rates than any other bacteria in our study followed by E.coli, Pseudomonas aeruginosa. Prevalence of Klebsiella spp. is found to be 41.8% in which Carbapenem resistance is found to be 8.5%. Among them about 72.7% are confirmed for Carbapenemase production by mCIM and Rapideccarba NP test and 62.5% isolates are confirmed for MBL production by eCIM tests. This study exemplified that the more number of the Klebsiella spp. strains are found to be resistant to numerous antibiotics. To prevent infections due to multidrug resistant Klebsiella spp., a well formed team consisting of eminent treating clinicians, clinical microbiologists and the infection control team’s participation with appropriate intercommunication, focussed target action is much need of the hour.

Geographic information systems, the integration technique of multi-criteria assessment, together with the analysis hierarchy process, are recognized in decision support to describe and predict locations for implementation of different projects. In Brazil, shrimp farming has been consolidated for more than 30 years in the Northeast and North regions and is emerging in the Southeast. The purposes of this study were to analyze, classify and quantify through spatial planning for the establishment of shrimp farming in the North Fluminense region of the state of Rio de Janeiro, Brazil. The composition of the final model was structured into hierarchical categories with two models, factors, and constraints. The model of factors was subdivided into five sub-models: water abstraction, environmental, transport, public, and economic infrastructure. In turn, restrictions were composed of urbanized areas, environmental reserves. The best areas were identified as those that were flat, close to rivers, related to theenvironmental sub-model criteria (21%); followed by the sub-models of public, economic, and water abstraction infrastructure (20%), and transport with the lowest weight attributed (17%). The analyses indicated a great potential for the implementation of shrimp farming in the region, estimated in a total area of 628,088 ha, classified as adequate or very adequate (> 0.6).

Long-term outcomes from the UK Biobank on the impact of coffee on cardiovascular disease, arrhythmias, and mortality: Does the future hold coffee prescriptions?
Authors: Kotit Susy
Published: June 2023

Coffee is a popular beverage and the most used psychostimulant worldwide. Habitual coffee consumption has been linked to a growing list of health benefits; however, coffee consumption has been a source of longstanding debate. Recent observational studies have challenged the misconception of caffeine and reported the safety and beneficial effects of coffee intake on a range of cardiovascular (CV) conditions, including coronary artery disease, arrhythmias, heart failure, and stroke, leading to a decreased risk of CVD, all-cause and CVD mortality, and being associated with favorable CV outcomes. However, the mechanisms underlying the protective effects of caffeine remain speculative, and there is a lack of dedicated studies aimed at addressing the impact of different coffee subtypes on clinical outcomes such as CVD, arrhythmia, and mortality.
Lessons from a pre-specified meta-analysis of sodium-glucose cotransporter-2 (SGLT2) inhibitors in heart failure: Time for new clinical recommendations
Authors: Kotit Susy
Published: June 2023

Cardiovascular disease remains the leading cause of death worldwide with heart failure (HF) being one of the significant contributors to morbidity and mortality. The incidence of HF with preserved ejection fraction (HFpEF) is increasing, especially in young adults making it a growing public health matter. Sodium–glucose cotransporter-2 (SGLT2) inhibitors have been shown to reduce the development, progression, and mortality of heart failure in patients with reduced EF regardless of patients’ diabetes status but their clinical benefits in patients with heart failure and preserved ejection fraction are less well-established. Recent trials have shown reductions in cardiovascular death and heart failure events in patients with mildly reduced or preserved ejection fraction (EF), although with uncertainty around the consistency of clinical benefits across the classes and therapeutic effects.

Published: June 2023

The 2016 Albert Lasker Basic Medical Research Award and subsequently the 2019 Nobel Prize in Physiology or Medicine were awarded to William Kaelin, Jr., Sir Peter Ratcliffe, and Gregg Semenza for their work on how cells sense and adapt to hypoxic conditions. Their work showed that the changes in gene expression, cell metabolism, and tissue remodelling that occur in response to low oxygen concentrations are orchestrated by the transcription factor, hypoxia inducible factor-1a (HIF-1a). While the effects mediated by HIF-1a have been widely studied, its role in heart valves has only recently been investigated. These studies have shown that HIF-1a expression is evident in mechanisms that regulate the structure and function of heart valves. These include embryonic development, the regulation of the extracellular matrix, angiogenesis and the initiation of the calcification process. This review provides a background on the role and function of HIF-1a in response to hypoxia and a discussion of the available evidence of its involvement in the regulation of heart valves in health and disease.

The objective of the current study was to assess the relative agility T-test as a measure of change of direction speed and establish normative data specifically for children aged 10-11. A sample of 350 boys and 220 girls within the specified age range, with no medical history of disease, was randomly recruited from various schools. The mean and standard deviation, as well as the range of values, were determined for several variables including age, body mass, height, and BMI for both boys (n=350, age=10.83±0.38 years, body mass=34.42±5.61 kg, height=1.44±0.06 m, BMI=16.59±2.13 kg/m²) and girls (n=220, age=10.79±0.41 years, body mass=34.85±6.36 kg, height=1.44±0.07 m, BMI=16.61±2.15 kg/m²). The T-test, along with the FCMJ and 30mSS tests, were performed at least three times with a three-minute recovery period between trials and a five-minute recovery period between tests. Test-retest reliability of the T-test was evaluated using the intraclass correlation coefficient (ICC), which yielded values of 0.95 for girls and 0.97 for boys. Significant correlations were observed between the T-test and FCMJ as well as the 30mSS for girls (r=-0.384, p<0.0001 and r=0.416, p<0.0001, respectively) and for boys (r=-0.344, p<0.0001 and r=0.440, p<0.0001, respectively). The study provides percentile values that can be utilized to monitor the physical fitness levels of both girls and boys.

The paper presents the results of experimental study of heating and evaporation of TS-1 aviation kerosene and its surrogates (n-decane and SU4) in a high-temperature gas flow (gas temperature range is 450–750 K, gas flow velocity range is 0–6 m/s). The conditions for temperature and gas flow rate are established, under which it is possible to provide good agreement on the time of complete evaporation, the dynamics of changes in the sizes (radii) and average temperatures of droplets of traditional aviation fuels using the example of kerosene TS-1 and its surrogates (SU4 and n-decane). When processing videograms, we used our own image processing algorithms developed in the MATLAB software package.

The nonlinear shift of the resonant frequencies of a microwave active ring resonator (ARR) induced by a pump wave has been studied for the first time. The resonator was designed according to the scheme in the form of a closed ring containing a spin-wave delay line made on the basis of a one-dimensional magnonic crystal, as well as a microwave amplifier in a feedback circuit. It is shown, that with an increase in the power of the pumping wave, the shift of the resonant frequencies of the ARR increases in different ways depending on the position of the pumping frequency. The maximum induced nonlinear frequency shift is observed if the pumping frequency is at the minimum of the ARR transmission coefficient. A model describing the studied effect is developed.

Published: June 2023

Abstract: Electric vehicles (EVs) are a promising technology for achieving a sustainable transport sector due to their very low to zero carbon emissions, low noise, high efficiency, and flexibility in grid operation and integration. This chapter includes an overview of electric vehicle technologies as well as associated energy storage systems. Different types of electric-drive vehicles are presented. Also, if hazardous gas is detected inside of the cabin such as CO2 gas as a result of occupants of the vehicle, the system will open windows of the vehicle automatically. The advantage of this system is proper detection and faster response time leading to faster diffusion of the situation, compared with the manual methods. The gas sensor used in this project is MQ-7 and MQ-135 which detects the presence of hazardous gases both inside and outside of the vehicle cabin. These sensors will detect the concentration of the gas according to the voltage output of the sensor. To make the sensors operate in the control and data monitoring system, Arduino Uno was used as the microcontroller for the whole system. The circuit also includes Servo motor, buzzer, exhaust fan and LCD screen.

Abstract: Nowadays, the earth’s surface receives UV radiation directly due to ozone layer depletion, which raises temperatures and heat at the equator and the tropic of cancer, regions like the Indian sub-continent. It consequently hampers the steady vehicles by damaging their working components. Therefore, this investigation focuses on the selection of roof-top heat-resistant covers for sedan cars in the Indian sub-continent. Four different types of heat-resistant covers viz. Taffeta material, Fibreglass cloth, Silicone rubber sheet, and Double-sided silicone-coated fibreglass cloth (DSFC) are studied in correlation with the external and internal temperatures with different time intervals such as 10min, 30min, 60min, and 180min respectively. The internal and external temperatures were measured using a temperature sensor. In conclusion, the heat-resistant roof-top has significance in resisting heat. The overall results showed that the double-sided silicone-coated fibreglass cloth was found to be more effective than other materials.
Fyodor Dostoevsky in 21st-Century Foreign Research
Authors:   State Institute for Art Studies, Evallyo Violetta D.
Published: June 2023

This article attempts to provide an overview of foreign monographs and collective works that have been published in the 21st century, as well as some significant translations and reprints. This review cannot claim to provide an exhaustive overview of all authors’ approaches, but some conclusions can be drawn from it anyway. Firstly, the identified problems which are in the focus of contemporary researchers differ in many respects from those which were the focus of attention of researchers in previous decades, and this seems to be due to the issues that concern different generations. The focus of scholars’ attention is still on ontological problems, eternally troubling humans – questions of spirituality, good and evil, humanism and the limits of the mankind, however, more and more space is occupied by contemporary issues: intolerance, femininity, trauma, deviancy, cruelty, nihilism. In Dostoevsky’s works, researchers are attracted by the prophetic motifs of the consequences of the loss of spirituality and ethical foundations – and possible ways of redemption.
Napoleon-Sun in Dostoevsky’s Novel Crime and Punishment

Published: June 2023

The article is dedicated to the historical and cultural fusion of the Napoleonic and solar myth and its reflection in Dostoevsky’s novel Crime and Punishment. The plea of investigator Porfiry Petrovich to Rodion Raskolnikov during their third conversation “to become the sun” affects not only the Christian, as many researchers have already noticed, but also the Napoleonic side of the personality of the hero, who is trying to become the new Petersburg’s legislator of humanity. Special attention is paid to the evolution of the concept of “the Sun of Austerlitz,” which is usually understood as the highest triumph of Napoleon during his entire military career, and the centennial tradition of identifying great rulers with the Sun (Alexander the Great, Julius Caesar, Louis XIV, Napoleon, etc.). The formation of the solar cult of Napoleon during the First Empire in France and the role of the sun in the novel Crime and Punishment are considered in detail. It is explained why Raskolnikov, whose name Rodion refers to the island of Rhodes, dedicated to Helios, the god of the sun, mentions a variety of battles and campaigns involving his idol (the Siege of Toulon, the Egyptian campaign, the crossing of the Alps, the War of 1812, Waterloo, etc.) but completely ignores the Battle of Austerlitz, and why the sun the hero comes across is almost always setting. In addition, the article traces the connection between Napoleon and Apollo in the European culture of the first half of the 19th century and in Dostoevsky’s work.
Pulmonary atresia and ventricular septal defect: How accurate is the fetal echocardiography, and do the major aortopulmonary collateral arteries matter?

Published: June 2023

Objective: To assess the accuracy of prenatal echocardiography in
defining pulmonary vasculature in pulmonary atresia with VSD (PAVSD).
The second aim is to compare the perinatal and postnatal outcomes of
different pulmonary blood supply types. Design:The cases prenatally
diagnosed with PAVSD between January 2017- October 2022 in a single
tertiary fetal medicine center were identified on the electronic
database. Fetal echocardiography reports and images were reviewed
retrospectively. Postnatal outcomes and images were acquired from the
hospital records of relevant pediatric cardiology and cardiovascular
surgery clinics. Fetal echocardiography results were compared with
postnatal results. Perinatal and postnatal outcomes were compared
between the pulmonary vascular supply types. Results: Among the 24 PAVSD
cases, six were diagnosed with major aortopulmonary collateral arteries
(MAPCA) dependent, eleven were diagnosed with ductus arteriosus (DA)
dependent pulmonary vascular supply, and seven were diagnosed with
double pulmonary supply (MAPCA + DA) on prenatal echocardiography.
Seventeen cases were live-born and have undergone postnatal
investigations. Fetal echocardiography was 88.2% accurate about the
type of pulmonary vascular supply. The accuracy of fetal
echocardiography regarding pulmonary vascular anatomy was 82.3%. Four
cases were demised before surgical interventions. Postoperative survival
was 69.2%. Mortality and postoperative survival did not differ between
pulmonary supply groups. Survival was disrupted with extracardiac
anomalies. The need for early surgical interventions was significantly
higher in the DA group. Conclusion:The anatomy of pulmonary
vascularization in PAVSD can be defined precisely on fetal
echocardiography. The source of pulmonary blood supply does not impact
postnatal short-term outcomes significantly; however, it affects the
postnatal management. The associated anomalies highly contribute to
postnatal mortality. Therefore, MAPCAs, the anatomy of the pulmonary
arteries, and accompanying abnormalities should be intensely searched on
fetal ultrasonography.
