Authors: Bowen Adam , Soltani Aria , Cloud Adam , Polavarapu Hanish , Lodi Yahia
Published: June 2023

Background: Surpass streamline flow diversion is performed by transfemoral, transradial or both approaches. Safety and feasibility of direct carotid artery cutdown and is not known. Objective is to report Surpass streamline flow diversion via direct carotid artery utdown for a patient with bilateral internal carotid artery dissecting pseudoaneurysm. Method: Case report. Outcome was measured using modified ranking scale (mRS). Results: Sixty-seven-year-old man with history of repaired aortic arch dissecting aneurysm using aortic stent, developed worsening headaches and dizziness and diagnosed with bilateral internal carotid artery dissecting pseudoaneurysm on a computed tomographic angiography; right internal carotid artery dissecting pseudoaneurysm measured 19x15x20 mm and left was 16x9x22 mm. Digital subtraction angiogram was attempted but failed. A direct carotid artery cutdown followed by surpass streamline flow diversion was performed in a staged fashion. A 6-french sheath was placed from right common carotid artery to right internal carotid artery by a vascular surgeon and was confined with digital subtraction angiography. An intermediate catheter was navigated to the internal carotid artery beyond the internal carotid artery dissecting pseudoaneurysm and surpass streamline flow diversion was achieved with 3 devices; 4x50 mm x2 and 5x40 mm. Carotid artery cutdown site was sutured by vascular surgeon. Patient was extubated and discharged home in 48 hours with NIHSS 0 and mRS1 at his baseline. The left internal carotid artery dissecting pseudoaneurysm was repaired after 3 month using similar technique as described above with two 5x50 mm flow diverters. For the second procedure, angioplasties were required for better appositions of flow diverters. Patient was discharged home in 24 hours. Patient’s symptoms resolved and resumed baseline activities. Prescribed to continued 325 mg aspirin and 75 mg clopidogrel for six months followed by 162 mg aspirin and 75 mg of clopidogrel. Patient maintained mRS 0 in follow-up visits but refused to have a computed tomographic angiography, which finally performed in 24 months, demonstrates complete obligations of the left internal carotid artery dissecting pseudoaneurysm but occlusion of right internal carotid artery with robust collaterals from left internal carotid artery through collaterals. Patient admits premature discontinuation of antiplatelets when he learned about his computed tomographic angiography results. Conclusion: This is the first report of treatment of bilateral internal carotid artery dissecting pseudoaneurysm repaired by direct carotid artery cutdown approach. This is also the first report of a patient with an aortic arch stent, who developed bilateral internal carotid artery dissecting pseudoaneurysm and direct carotid artery cutdown required for treatment. Additionally, antiplatelets must be continued to prevent device occlusion.
Infections May Cause Arterial Inflammation, Atherosclerosis, Myocarditis and Cardiovascular Disease
Authors: Ravnskov Uffe , Alabdulgader Abdullah , McCully Kilmer
Published: June 2023

Effective prevention and treatment of atherosclerosis and cardiovascular disease (CVD), the commonest cause of death in most countries, is still lacking. For many years we have studied the cholesterol hypothesis and found that there are many contradictions to this hypothesis. For instance, no trial has shown exposure response; the lipid values are not associated with degree of atherosclerosis, and people with high LDL-C live just as long or longer than people with low LDL-C. These facts together with the observation that inflammation is a common finding in atherosclerotic arteries have probably contributed to the hypothesis that CVD may be caused by inflammation. However, several trials with anti-inflammatory drugs have shown that such treatment increases the risk of CVD. Therefore, a relevant hypothesis is whether it is infections which cause the inflammation and whether CVD may be caused by infections because many human observations and animal experiments are in accordance with this idea. As cholesterol-lowering treatment is ineffective and may cause serious side effects, we believe that future research should elucidate the importance of infections in the etiology of CVD. A relevant method would be to perform a blood culture on all patients with an acute AMI and if it is positive, to treat the patient with an appropriate antibiotic.

Authors: Cocho Dolores , Martínez-Rivas J J , Monterroso Y , Cuadrado M
Published: June 2023

Background: Currently there is no predictive model in acute minor stroke without large vessel occlusion. Aims: Our objective was to evaluate the independent predictors that correlate with unfavourable outcome and to develop a predictive scale in acute setting. Methods: Retrospective analysis of consecutive acute minor stroke (NIHSS <5) admitted within 4.5 hours to clinical onset who were previously not disabled and without large vessel occlusion on CT angiography (intracranial or extracranial occlusion or stenosis ≥50%). Unfavourable outcome was defined as modified Rankin Scale 3-6 at 90 days. Independent predictors of disability were included in the model. Results: A total of 408 patients with acute minor stroke (NIHSS <5) were analyzed. Large vessel occlusion was detected in 83 (20%), who were excluded. The final analysis included 325 patients, with mean age of 68± 14 years, 59% were men and 14.5% had unfavourable outcome. On multivariate analysis, age >70 years, NIHSS >2, recurrent event, posterior circulation ischemia and previous stroke were associated with unfavourable outcome. Recurrent event was excluded to the model because this variable is not available in acute setting. With the variables detected in the logistic regression, a predictive model was made (SPAN2 scale: previous Stroke, Posterior ischemia, Age >70 or NIHSS >2). The model correctly classified 84% of the patients with unfavourable outcome. A score >2 points on the SPAN2 scale showed a sensitivity 95%, specificity 51%, PPV 25% and NPV 99% of unfavourable outcome at 90 days. Conclusions: SPAN2 scale could be useful to stratify the risk of unfavourable outcome in acute phase of minor stroke without large vessel occlusion. Future studies may validate its usefulness in the selection of patients for thrombolytic therapy.
Emerging Value-Based Radiology in the Era of Artificial Intelligence
Authors: Mun Seong , B. Lo Shih-Chung , Wong Kenneth , Koh Dow-Mu , Prior Fred
Published: June 2023

Radiology has a long history of adopting state-of-the-art digital technology to provide better diagnostic services and facilitate advances in image-based therapeutics throughout the healthcare system. The radiology community has been developing diagnostic artificial intelligence (AI) tools over the past 20 years, long before AI became fashionable in the public press. Currently, there are approximately four hundred Food and Drug Administration approved imaging AI products. However, the clinical adoption of these products in radiology has been relatively dismal, indicating that the current technology-push model needs to evolve into the demand-pull model. We will review the current state of AI use in radiology from the perspective of clinical adoption and explore the ways in which AI products will become an ensemble of critically important tools to help radiology transition from volume-based service to value-based healthcare. This transition will create new demands for AI technologies. We contrast the current “technology-push” model with a “demand-pull” model that will aligns technology with user priorities. We summarize the lessons learned from AI experience over the past twenty years, mainly working with computer-aided detection for breast cancers and lung cancers. The radiology community calls for AI tools that can do more than detection with increasing attention toward higher workflow efficiency and higher productivity of radiologists. Major radiological societies of North America and Europe promulgated the emerging concept of value-based radiology service, an integral part of overall value-based healthcare. The transition to value-based radiology will happen and that higher value will come from the effective use of AI throughout the radiology workflow. The value-based radiology will need to work with a full range of machine learning tools, including supervised, unsupervised, and reinforcement learning, as well as natural language processing and large language models (e.g., chatbots). The engineering community is rapidly developing many concepts and sophisticated software tools for data orchestration, AI orchestration, and automation orchestration. Current radiology operation has been supported by PACS, a monolithic IT infrastructure of past generations. This system will need to migrate to an intelligence management system to support the new workflow needed for high value radiology.

English translation. The original article can be found here

Challenges to the teaching of religion are analysed from different perspectives and in different aspects. In the diagnosis of problems, one of the most important factors is the opinion of religion teachers who confront these challenges directly and on a daily basis. This article is an analysis of the results of a survey of religion teachers in this context. Challenges from the students, from the parents, from the institutional Church, from the school and challenges from the parish are discussed. Among the most serious challenges is the lack of faith of the pupils and the lack of need for faith development were identified. The research shows that the strongest correlate of attitudes towards Religious Education at school is religious indifference and waning religiosity.
Colonel Łukasz Ciepliński (1913–1951) as a Personal Pattern in the Christian Formation of Men. A Study Based on His Prison Grips
Authors: Rybicki Adam
Published: June 2023

English translation. The original article can be found here

The article presents the personality and spirituality of the Polish soldier, Colonel Łukasz Ciepliński (1913–1951), as a personal role model for contemporary men. The main source is secret messages written by him from a prison cell, which are an extremely valuable document about this character. The article presents the personality and male characteristics of a Polish officer: internal integration, maturity, bravery, care for others. There are also signs of the great respect he had for family values, for he was himself a husband and father. Another issue is his Christian spirituality: in suffering, like many prominent figures of the Church, he shows an extraordinary increase in theological virtues (faith, hope and love) as well as union with Christ and readiness for martyrdom.

Authors: Kaur Rajbir , Kaur Arvinder , Kaur Satinder
Published: June 2023

The present study explored the potential use of brain anti-oxidative enzymes as pollution biomarkers in fish Labeo rohita. Experiments were conducted to see the neurotoxic effects of dye Basic violet-1 on fish brain enzymes such as lactate dehydrogenase, alkaline phosphatase and acid phosphatase. Acute toxicity tests were performed for 96 hrs with dye concentrations of 0.2 (LC20), 0.4 (LC40), 0.6 (LC60), 0.8 (LC80) and 1 (LC100) mg/l to study biochemical changes. Behavioural observations were also recorded. Recovery experiments were run for 15 and 30 days. Exposure to the dye adversely affects the brain of the fish as evidenced by altered swimming behavior. Significant dose and duration-dependent increase in enzyme activity was recorded for alkaline phosphatase and acid phosphatase while lactate dehydrogenase activity showed a decrease when compared to the control. Lactate dehydrogenase was found to be a maximally affected enzyme as the percentage change over control is 301.26%. The results indicate prolonged neurotoxic effects of the dye as indicated by the altered swimming behaviour and enzymatic profile of fish. The present study recommends the use of L. rohita as sentinel species in water quality studies and supports the incorporation of fish biochemical profiles as a biomarker in water/ wastewater monitoring programs.

Предложен алгоритм численного решения уравнения Фредгольма второго рода с непрерывным ядром методом замены интеграла и матричным решением СЛАУ с квадратурной формулой двенадцатого порядка погрешности с числом интервалов интегрирования кратным десяти. Новая формула по сравнению с формулой Симпсона дает 15 значащих цифр для узловых значений функции решения даже при небольшом числе интервалов 10,20 на отрезке за конечное число элементарных операций. Полученный алгоритм имеет двойную точность и минимальное время вычислений. В то время как формула Симпсона совместно с матричным методом решения СЛАУ дает только 6 значащих цифр с числом интервалов интегрирования равным двадцати. Более того, для формулы Симпсона двойная точность недоступна (15 нулей в бесконечной норме невязки решения), так как язык FORTRAN допускает максимальные массивы матриц 200×200. Получены оценки верхней границы допустимого параметра |λ| для матрицы уравнения Фредгольма со строгим диагональным преобладанием или с небольшой нормой интегрального ядра.

Published: June 2023

Background. Diagnosis of acute myocardial infarction (AMI) in pubertal patients is a diagnostic challenge, as individuals of such a young age usually do not have traditional risk factors for coronary heart disease (CHD) and, as a result, are at increased risk of misdiagnosis.

Objective. To describe a clinical case of AMI in a 16-yearold patient against the background of complete well-being.

Design and methods. A 16-year-old patient, against the background of complete well-being, developed pressing pains in the chest, which stopped on their own after a few hours. During hospitalization, in addition to an increase in the level of troponin, the results of other laboratory and instrumental studies did not confirm the version of AMI, as a result of which other cardiac and non-cardiac causes of the development of chest pain formed the basis of the diagnostic search. This was the reason for the delayed diagnosis and endovascular treatment of thrombotic occlusion of the right coronary artery, and, as a result, the formation of an area of persistent hypokinesia of the lower parts of the left ventricle. Further search for possible causes of AMI, including the analysis of genetically associated conditions, did not yield results.

Results. This publication describes a case of acute inferior myocardial infarction with ST segment elevation and thrombotic occlusion of the right coronary artery in a 16-year-old adolescent and the impact of an irrational diagnostic process on long-term prognosis.

Conclusion. The presented clinical case demonstrates the importance of including the diagnosis of AMI in the process of differential diagnosis of acute chest pain, even in adolescent patients.

Authors: Kumar Kanwar , Chauhan Vikas
Published: June 2023

Cotton leafhopper, Amrasca devastans has become very serious pest in recent years. Both nymphs and adults suck the sap from under surface of the leaf causing specking symptoms, crinkling and distortion of leaves and reddening all along the sides of leaves with downward curling. A. devastans caused significant damage during early stage by sucking the cell sap of the cotton leaves. The incidence of leafhopper was recorded from 23rd SMW to 38th SMW at seven days interval. The maximum leafhopper population on RCH 650 BGII Bt (2.26/ leaf) was found during 33rd SMW and on H-1098-i non-Bt (1.89/ leaf) was found during 32nd SMW. Throughout the season the leafhopper incidence was found lower than the economic threshold in H-1098-i non-Bt. Nymphal population exhibited significant positive correlation with relative humidity and rainy days.

The bending force of chickpea plants was found in the range 1.25 to 27.28 N for 6´10-3 to 1×10-2 m stem diameter at 17.44 to 13.13% moisture content.
Deciphering Biochemical Traits in Selected RILs of Mungbean [Vigna radiata (L.) Wilczek] against Bruchids (Callosobruchus maculatus F.)
Authors: Lekshmi J.K. , Kennedy J.S. , Uma D. , Senthil N. , Murugan M. , Malarvizhi D.
Published: June 2023

Background: Mungbean [Vigna radiata (L.) Wilczek] is a vital pulse crop having a colossal nutritionary and gastronomic significance. The bruchid, Callosobruchus maculatus is recognised as the most heinous storage pest of leguminous crops that causes drastic economic loss. Crop breeders may use the nutritional and antinutritional traits of seeds to successfully combat storage pests. Methods: The present investigation has been framed to compare the degree of seed damage and weight loss with the biochemical parameters, viz., starch, sugar, protein, phenol, tannin and alpha-amylase inhibitor, of mungbean seeds from parental and selected lines of F5 populations for bruchid resistance. Result: The resistant parent, V2802BG and seven F5 families (BSR-GG-1-49-2, BSR-GG-1-49-5, BSR-GG-1-56-5, BSR-GG-1-170-5, BSR-GG-1-198-2, BSR-GG-1-198-3, BSR-GG-1-160-1) were completely resistant to bruchid infestation with no seed damage. One of the probable reasons for the stunted development of Callosobruchus maculatus might be the high level of phenol. Seed weight loss and damage by bruchids were shown to be positively correlated with high levels of protein, starch and sugar; however, alpha-amylase inhibitors and tannins did not reach statistical significance at the 5% level.

The idea of limit is central to both differential and integral calculus. It is also applicable in other disciplines such as physics, engineering, economics, etc.  Because of this, conducting a study to further improve teachers’ knowledge about how social science students (whose major is economics) understand limits is of utmost importance. The reported study sought to find out how students understand the idea of limit with regard to the use of its symbolism. Sixty first year university students in the social sciences acted as the sample of the study. An adapted procept theory was used to analyse data obtained from these students through their solution to tasks on limit and explanations on their thinking and solution processes. Qualitative analysis of data indicated that some students understood the limit symbolism  to be a procept while others did not. When solving the mathematical tasks, students’ difficulties emanated from: (i) their inability to coordinate the two processes,  and , or  and  (ii) the proper use of the limit operator,  and (iii) inability to realise that the simplification has led to the same response as they could not see the relationship between the results. This resulted in misalignment between their reasoning and their choice of answers where justification was required. The results also show that limits at infinity were more problematic than those of the form  as where a is a constant. Students’ choice of method used depended mostly on how much efficient the method was in terms of saving time and not really on promoting understanding. The lesson learnt from the study is that when using the adjusted procept theory, the yes or no answers do not qualify to be used in concluding the level of thinking at which students are at. It is recommended that students be asked to show their working and also explain their answers so that the type of understanding that leads to their choices come to fore

Cedrus atlantica is a tree species present in the south of France which, in the context of climate change, could become a conservation priority in the coming years. This tree species is also of considerable ecological and socio-economic interest in the Mediterranean Basin area, where it is mainly recognized for its durable timber, and also for the potentially interesting chemical properties of its essential oil. Studies of its heartwood formation and the properties of its extractives are therefore of interest, although very few have been conducted so far.
The radial distribution of water/acetone extractives within the Atlas cedar tree (bark, sapwood, transition wood, outer heartwood and inner heartwood) selected for this study was screened at different tree height levels. High-performance liquid chromatography (HPLC) analyses were performed, especially to characterize flavonoid compounds in these extractive fractions. The radial variation of the extractive composition obtained highlights the phenomenon of heartwood formation. Assumptions were put forward as to the metabolic pathways involved in the heartwood formation process of cedar wood, based in particular on the occurrence and radial evolution of (-)-catechin, (+)-taxifolin and flavan compounds. The fungicidal and termite-repellent activities of the extracts were then tested. The water/acetone extractives from the Cedrus atlantica individual studied showed strong termite repellent activity and moderate antifungal activity against crop and fruit pathogens. Even though the sampling in this study was limited to a single tree, the results point to a potential for commercial use of Atlas cedar extractives as wood preservatives and/or as biocontrol products against pathogens of woody agricultural crops. Additional tests and chemical analyses will be carried out to confirm these interesting preliminary results.

Charcoal briquettes made from a mixture of alaban charcoal and coconut shell are one of the efforts to utilize waste. The purpose of this study was to determine the variation of the mixture of alaban charcoal powder and coconut shell on the quality of charcoal briquettes. The mixture of raw materials uses 5 variations, namely 1) 100% charcoal; 2) 75% alaban charcoal and 25% coconut shell; 3) 50% alaban charcoal and 50% coconut shell, 4) 25% alaban charcoal and 75% coconut shell; and 5) 100% coconut shell. The resulting data were then analyzed by variance and compared with ASTM. The quality of charcoal briquettes is not affected by the composition of the mixture of alaban charcoal and coconut shell. Treatment with 100% coconut shell raw materials, without a mixture of alaban charcoal, is charcoal briquettes with the quality closest to ASTM standards, in the form of ash content, volatile matter, calorific value. Other parameters such as water content, density and bound carbon still do not meet ASTM standardsBriket arang terbuat dari campuran arang alaban dan tempurung kelapa adalah salah satu upaya salah satu upaya pemanfaatan limbah. Tujuan penelitian ini adalah mengetahui variasi campuran serbuk arang alaban dan tempurung kelapa terhadap kualitas briket arang. Campuran bahan baku menggunakan 5 variasi yaitu 1) arang alaban 100%; 2) arang alaban 75% dan tempurung kelapa 25%; 3) arang alaban 50% dan tempurung kelapa 50%, 4) arang alaban 25% dan tempurung kelapa 75%; dan 5) tempurung kelapa 100%.
