Suitability of pollen as an alternative food source for different developmental stages of Amblyseius herbicolus (Chant) (Acari: Phytoseiidae) to facilitate predation on whitefly eggs
Authors: Xin Tian-Rong , Zhang Zhi-Qiang
Published: October 2021

Alternative food sources could sustain predator populations by influencing their performances including predation, development, and reproduction in periods of shortage or scarcity of prey under laboratory or fields conditions. The aim of this study was to explore suitability of cattail pollen (Typha orientalis) as an alternative food source for different stages of Amblyseius herbicolus (Chant) (Acari: Phytoseiidae) on their predation capacity against the eggs of whitefly Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae), and the developmental and reproductive responses of the predators to different diet switching regimes under laboratory conditions (T1: nymphs and early adults fed pollen; T2: nymphs fed pollen but early adults fed whitefly eggs; T3: nymphs fed whitefly eggs but early adults fed pollen; T4: nymphs and early adults fed whitefly eggs). Results in the diet switching experiment revealed that although A. herbicolus could prey on whitefly eggs in all the treatment groups, the predatory mites obviously differed in their capacity to prey on the target pest whitefly eggs when fed on cattail pollen and whitefly eggs during different developmental stages. A. herbicolus in group T2 revealed the highest average predation rate, being 1.31, 1.17, and 1.49 times those in groups T1, T3, and T4, respectively. Our results indicated that food sources including cattail pollen and whitefly eggs were suitable for A. herbicolus, because it was able to develop from egg to adult females in all the treatment groups. The mixed diets (T2 and T3 groups) revealed positive effects on the developmental and reproductive parameters of A. herbicolus females, leading to higher oviposition rates and shorter developmental durations when compared with those of groups T1 and T4. A. herbicolus in group T2 revealed the highest average oviposition rates (1.32, 1.26, and 1.81 times those in groups T1, T3 and T4, respectively); however, no significant differences were observed between the T1 and T3 groups. All the eggs of A. herbicolus succeeded in reaching adulthood, but the duration of egg to adult developmental time of A. herbicolus was different among the four treatment groups. The longest and shortest developmental times were obtained in groups T4 and T3, respectively. All the results in the present study demonstrated that A. herbicolus adult females can prey on T. vaporariorum eggs, and cattail pollen was suitable as an alternative or additional food source with high nutritional value for this predatory mite to enhance the predation capacity towards whitefly eggs because A. herbicolus can successfully complete its immature development as well as reproduction.
Covid-19 as occupational disease in healthcare workers: a brief review of cases in the Clinical Hospital Centre Rijeka, Croatia
Authors: Lalić Hrvoje
Published: September 2021

The coronavirus disease 19 (COVID-19) pandemic has had a tremendous impact on every facet of private life and work organisation in virtually all social and economic sectors worldwide. People who stand on the first line of defence are healthcare workers (HCWs) risking exposure to infected patients. However, even though they are often affected by COVID-19 and associated somatic and mental health problems, COVID-19 as a new illness was not immediately acknowledged as occupational disease. This is why several groups of HCWs contacted their occupational medicine physicians in 2020 with a request to register the infection with SARS-CoV-2 as occupational disease. In an attempt to support their appeals and show that hospital workers have a high occupational risk of COVID-19, this study presents COVID-19 incidence and symptoms in 100 employees working at 11 clinics of the Clinical Hospital Centre (CHC) Rijeka, Croatia from 1 June to end December 2020. All of them were infected with SARS-CoV-2 and took sick leave, which lasted 13.6±2.6 days in average. This study also looks into the role of occupational medicine physicians in prospective monitoring of acute and long-acting consequences of COVID-19 that might occur in HCWs.
Job demands, job control, and social support as predictors of job satisfaction and burnout in Croatian palliative care nurses
Authors: Junaković Ivana Tucak , Macuka Ivana
Published: September 2021

The Job Demands-Control-Support (JDCS) model has seldom been tested in palliative care settings, and occupational well-being of palliative care professionals has never before been investigated in Croatia. Our aim was therefore to fill that gap by testing the JDCS model among Croatian nurses providing palliative care. More specifically, we wanted to see how job demands, job control, and social support at work affect occupational well-being outcomes (i.e. job satisfaction and burnout dimensions of exhaustion and disengagement from work) in terms of the model’s iso-strain and buffer hypotheses. This cross-sectional study included 68 nurses working in various palliative care institutions across Croatia, who answered our online questionnaire. Overall, the nurses did not report high levels of burnout or low job satisfaction. The only significant effect was that of job control on job satisfaction (β=0.38; P<0.01) and disengagement (β=-0.45; P<0.01), while job demands and social support at work had a significant interaction effect on the burnout dimension of exhaustion (β=0.39; P<0.01) in the sense that high social support at work buffered the increase in exhaustion associated with high job demands. These findings suggest that interventions aimed at increasing perceived job control and social support at the workplace could improve occupational well-being of nurses working in palliative care.
How Has Digitalisation Influenced Value in the Music Market?
Authors: Ali Muhammad Murtaza , Karlsson Jenny , Skålén Per
Published: October 2021

This paper focuses on how digitalisation has influenced actors’ value determination and value creation in the Swedish music market. It draws on the service-dominant logic (SDL) and the service ecosystem perspective to conceptualise value as co-created through the integration of resources by multiple actors in service exchange, enabled and constrained by institutions and institutional arrangements. Empirically, we draw on a qualitative study of the digitalisation of the Swedish music market that consists of fifty-two interviews with various actors. The findings suggest that digitalisation has influenced service engagement and consequently value creation and determination for various actors, and especially for consumers and producers. This paper contributes by integrating SDL and the service ecosystem perspective into music business research in a novel way to promote a deeper understanding of value, value determination, and value co-creation. This paper also contributes to SDL by suggesting that both value-in-exchange and value-in-use are important aspects of value determination and value co-creation.

Indonesia is a country with 4th largest population in the world. With that huge amount of population, the land capacity on the mainland is becoming more limited day by day, on the other hand, the unused land on the coast is still not utilized properly. The solution of that problem is by doing reclamation on the coast. Reclamation is an activity to increase the usability of land resources in the eye of the environmental side, social and economy by doing dropping, land drying, or drainage. Usually, the material for dropping reclamation is using cohesive soil. In this research, we will talk about driven pile foundation on reclamation land. Bearing capacity and concrete volume that would be used from every driven pile shape would be compared by paying attention from scouring effect that can decrease the bearing capacity of the pile. In this study, we will show the best driven pile shape that can be used on reclamation land.Indonesia merupakan negara dengan jumlah penduduk terbanyak ke empat di dunia. Dengan banyaknya penduduk di Indonesia mengakibatkan lahan di daratan semakin terbatas, sedangkan lahan di sekitar pinggir pantai masih banyak yang belum dimanfaatkan dengan baik. Solusi dari permasalahan keterbatasan lahan di daratan tersebut adalah dengan melakukan reklamasi pada daerah pinggir pantai. Reklamasi adalah sebuah kegiatan yang dilakukan dalam rangka meningkatkan manfaat sumber daya lahan yang ditinjau dari sudut lingkungan, sosial dan ekonomi, dengan melalui pengurugan, pengeringan lahan atau drainase. Pada umumnya material untuk pengurugan reklamasi adalah menggunakan tanah kohesif. Pada penulisan ini akan dibahas penggunaan fondasi tiang pancang pada tanah reklamasi. Daya dukung dan volume beton yang digunakan dari setiap bentuk tiang pancang tersebut akan dibandingkan dengan memperhatikan efek scouring yang dapat mengurangi daya dukung pada tiang. Sehingga hasil studi ini akan menunjukan bentuk tiang pancang manakah yang paling cocok digunakan pada tanah reklamasi.

Published: October 2021

Artykuł ma charakter przeglądowy, jego celem jest charakterystyka zakresu problemowego oraz metodyki prowadzenia badań ruchu turystycznego i konsumpcji usług turystycznych w polskich parkach narodowych. Pracę oparto na analizie materiałów zastanych oraz wywiadach z osobami odpowiedzialnymi za monitoring ruchu turystycznego i/lub działalność naukową w każdym z parków. W pierwszej kolejności uwagę skupiono na metodach pomiaru ruchu turystycznego, będącego podstawą do prowadzenia dalszych badań o charakterze jakościowym. Zwrócono uwagę na duże zróżnicowanie metodyczne w tym zakresie, które powoduje, że publikowane dane dotyczące poszczególnych parków narodowych nie są porównywalne. W dalszej części pracy dokonano przeglądu badań prowadzonych wśród turystów. Zaobserwowano charakterystyczny dla zdecydowanej większości parków brak ciągłości badań oraz brak koordynacji w zakresie stosowanej metodyki, które utrudniają lub uniemożliwiają opracowywanie analiz w szerszych skalach czasowych i przestrzennych (dla wielu parków). Problematyka badawcza jest zróżnicowana, liczne są prace określające profil turystów odwiedzających poszczególne parki narodowe, a także ich aktywność przestrzenną i motywy przyjazdów. Sporadycznie natomiast podejmowane są analizy preferencji i zachowań konsumpcyjnych gości na miejscowych rynkach turystycznych oraz zmian zachodzących w tym zakresie, a także oceny ekonomicznego znaczenia turystyki w rozwoju lokalnym.

The main purpose of this study is to develop and optimize a method based on the hydroalcoholic solvent extraction of rosmarinic acid (RA) which is an important active component in the polyphenolic profile of the plant and, stands out with its antioxidant, antibacterial, and antiviral properties, and other antioxidant components. Soft computing-based chemometric studies are needed to model and optimize complex processes such as extraction. In this study, the extraction conditions of bioactive RA from Ocimum bacilicum L., a valuable medicinal aromatic plant source, with green and simple technique, were modeled and optimized using chemometric methods. Additionally, it was also aimed to evaluate the potential of RA in O. basilicum with the amount of Total phenolic substance (TFM) and Total antioxidant activity (TAA). In the study, RSM-CCD/small factorial design was used, multi-response optimization was solved with the help of Pareto solutions, and the Desirability function was used to determine the optimum input variable values. As a result, optimum conditions of O. basilicum L. extraction, 47.7% EtOH concentration, 30.0 °C temperature, 77.6 min extraction time, and 10 mL/g solvent/solid ratio were found. Experimental results obtained under optimum conditions were 171.46±1.87 mg GAE/g, 4.76±0.32 mg Trolox/mL, and 8.93±0.65 mg/g for TPC, TAA and RA, respectively. The predicted results from the mathematical model were (172.26 mg GAE/g), (4.13 mg Trolox/mL) and (8.89 mg/g), respectively.

Occurrence of kleptoparasitic sarcophagid flies (Diptera: Sarcophagidae: Miltogramminae) in natural and human modified sites in Southern South American Andean landscapes
Authors: Mulieri Pablo R. , Patitucci Luciano D. , Dufek Matías I.
Published: October 2021

Sarcophagid flies belonging to the subfamily Miltogramminae are mainly kleptoparasites of bees and solitary wasps. Twenty-six locations were surveyed to accomplish the first specific exploration on the diversity of Miltogramminae in southern Andean areas of South America. We evaluated changes in abundance, richness and composition among habitat types to establish the effect of anthropization on the Miltogramminae community. Habitat types were considered as human modified (trails and roads, parks and meadows) and natural sites (watercourses and lake beaches, sandy and shrubby areas), distributed in two ecoregions (Valdivian forest and Patagonian steppe). We found differences in the capture rate and composition of Miltogramminae among habitat types. The species Opsidia intonsa Aldrich was highly dominant in samples, with higher proportional abundance in human modified habitats. Richness of Miltogramminae was higher in natural sites. Comparisons between the ecoregions surveyed indicated the genus Opsidia Coquillett did not show differences in abundance between ecoregions, whereas Senotainia Macquart was more abundant in the Patagonian steppe. The results provide evidence on the significant effects of human influence on landscapes in kleptoparasitic fly diversity. Slight modifications of natural areas (as proliferation of trails or isolated houses) should be addressed to evaluate the conservation of kleptoparasitic Diptera.

Published: October 2021

Here we report on the first peculiar detection of the spotted-winged drosophila, Drosophila suzukii (Matsumura) on Martín García Island, a wildlife refuge located in the Río de la Plata estuary, Argentina. Flies were collected using banana baited traps fermented with live yeast, in sandy areas with abundant presence of cactus in the interior of the island. The absence of cultivated host plants, e.g., fruit crops, and the small population of humans inhabiting the island make the presence of D. suzukii in this wildlife refuge unexpected. Previous detection of this fly in South America happened mostly within commercial fruit orchards and/or neighboring fields.

Published: October 2021

El aumento de la migración en Chile ha planteado importantes desafíos a su sistema educativo, especialmente para la educación básica. Estos nuevos estudiantes enfrentan dificultades y situaciones de exclusión que pueden incidir en su éxito o fracaso en el sistema, reflejado en su rendimiento académico. La presente investigación tuvo como objetivo caracterizar el rendimiento académico en matemática de los estudiantes inmigrantes en función de su estatus migratorio y sus características sociodemográficas, psicosociales y familiares. Para esto, se utilizó una metodología cuantitativa que consideró a todos los estudiantes de 8º básico de la Región Metropolitana (Chile) que rindieron la prueba nacional SIMCE (Sistema de Medición de la Calidad de la Educación) durante el año 2017. Se realizó un análisis a nivel descriptivo y bivariado mediante tablas de contingencia y comparación de medias. Los resultados dan cuenta un nuevo estatus migratorio de los estudiantes, denominado aquí como “nueva generación”, conformado por niños, niñas y adolescentes nacidos en otro país, con ambos padres chilenos o bien con madre chilena y padre extranjero. Esta nueva generación se caracteriza, entre otros aspectos, por obtener el más alto rendimiento en matemática, pertenecer a un nivel socioeconómico alto y asistir a establecimientos educativos particulares. La relación entre la condición de migrante y el rendimiento es significativa, existiendo diferencias en el rendimiento en matemática de los estudiantes migrantes en función de su estatus migratorio y sus características sociodemográficas, psicosociales y familiares.

Authors: Lagas Iris F. , van der Vlist Arco C. , van Oosterom Robert F. , van Veldhoven Peter L.J. , Reijman Max , Verhaar Jan A.N. , de Vos Robert-Jan
Published: October 2021

Objective

To determine the minimal clinically important difference (MCID) for the Victorian Institute of Sport Assessment-Achilles (VISA-A) score in patients with midportion Achilles tendinopathy (AT).

Design

Prospective cohort study.

Methods

We included physically active patients with midportion AT who received exercises and an injection. We measured the VISA-A score (ranging from 0 to 100 points, where 100 points represents a healthy tendon) at baseline and at 12 weeks and 24 weeks after treatment, and the 7-point Global Assessment Scale (ranging from “worse than ever” to “completely recovered”) at 12 weeks and 24 weeks after treatment. We dichotomized the Global Assessment Scale to not improved (“worse than ever” to “unchanged”) or improved (“moderately improved” to “completely recovered”). The area under the curve and the Youden's index value closest to 1 were determined for both MCIDs (12 and 24 weeks), with corresponding sensitivity and specificity.

Results

Sixty-four patients were included, and 61 patients (95%) completed the 24-week follow-up. The MCID was 14 points (95% confidence interval [CI]: 3, 19) over a 12-week period, corresponding to 57% sensitivity and 88% specificity. The MCID was 7 points (95% CI: −10, 28) over a 24-week period, with 85% sensitivity and 62% specificity.

Conclusion

A change in VISA-A score of at least 14 points after 12 weeks or at least 7 points after 24 weeks of exercise therapy and an injection reflects a meaningful change for physically active patients with midportion AT. J Orthop Sports Phys Ther 2021;51(10):510–516. doi:10.2519/jospt.2021.10040

To identify the most suitable existing generic and condition-specific health-related quality of life (HRQoL) patient-reported outcome measures (PROMs) for active youth with and without a musculoskeletal injury, based on measurement properties, interpretability, and feasibility.

Design

Systematic review of clinimetrics.

Literature Search

We searched MEDLINE, Embase, CINAHL, SPORTDiscus, PsycINFO, and Scopus from inception to April 30, 2020.

Study Selection Criteria

Records with original data describing the evaluation of a PROM or PROM subscale in active youth (15–24 years old) with or without a musculoskeletal injury were included. Non-English studies and those including individuals with a cognitive, developmental, or systemic condition were excluded.

Data Synthesis

This review was conducted according to the COSMIN user manual for systematic reviews of PROMs and the PRISMA guidelines. The COSMIN user manual guided our measurement property evaluation and interpretability and feasibility description.

Results

Of 6931 potential records, 21 studies were included. Eleven generic and 7 condition-specific PROMs were identified. No PROM received a final COSMIN recommendation of “A” because all lacked sufficient content validity. The 8-item Disablement in the Physically Active scale-mental summary component Short Form (DPA-MSC SF-8), Quality of Life Survey, and Functional Arm Scale for Throwers (FAST) were the most suitable existing PROMs, given their high-quality evidence for sufficient structural validity and internal consistency.

Conclusion

No definitively robust PROM for measuring generic or condition-specific HRQoL of active youth was identified. Until one exists, we recommend the DPA-MSC SF-8, the Quality of Life Survey, or the FAST and applying mixed methods to best characterize the HRQoL of active youth.

The Relationship Between Changes in Movement and Activity Limitation or Pain in People With Knee Osteoarthritis: A Systematic Review
Authors: Tan Jay-Shian , Tikoft Edward , O'Sullivan Peter , Smith Anne , Campbell Amity , Caneiro J.P. , Kent Peter
Published: October 2021

Objective

To report whether changes in knee joint movement parameters recorded during functional activities relate to change in activity limitation or pain after an exercise intervention in people with knee osteoarthritis (OA).

Design

Etiology systematic review.

Literature Search

Four databases (MEDLINE, Embase, CINAHL, and AMED) were searched up to January 22, 2021.

Study Selection Criteria

Randomized controlled trials or cohort studies of exercise interventions for people with knee OA that assessed change in knee joint movement parameters (moments, kinematics, or muscle activity) and clinical outcomes (activity limitation or pain).

Data Synthesis

A descriptive synthesis of functional activities, movement parameters, and clinical outcomes.

Results

From 3182 articles, 22 studies met the inclusion criteria, and almost all were of low quality. Gait was the only investigated functional activity. After exercise, gait parameters changed 26% of the time, and clinical outcomes improved 90% of the time. A relationship between group-level changes in gait parameters and clinical outcomes occurred 24.5% of the time. Two studies directly investigated an individual-level relationship, reporting only 1 significant association out of 8 correlations tested.

Conclusion

Most studies reported no change in gait-related movement parameters despite improvement in clinical outcomes, challenging the belief that changing movement parameters is always clinically important in people with knee OA. J Orthop Sports Phys Ther 2021;51(10):492–502. doi:10.2519/jospt.2021.10418

Published: October 2021

Synopsis

Participating in sport carries inherent risk of injury. Clinicians execute high-level clinical reasoning and decision making to support athletes to achieve the best outcomes. Accurately diagnosing a problem, estimating prognosis, or selecting the most suitable intervention for each athlete is challenging. Clinical prediction models are tools to assist clinicians in estimating the risk or probability of a health outcome for an individual by using data from multiple predictors. Although common in general medical literature, clinical prediction models are rare in sports medicine. The purpose of this article was to (1) describe the steps required to develop and validate (ie, evaluate) a clinical prediction model for clinical researchers, and (2) help sports medicine clinicians understand and interpret clinical prediction model studies. Using a case study to illustrate how to implement clinical prediction models in practice, we address the following issues in developing and validating a clinical prediction model: study design and data, sample size, missing data, selecting predictors, handling continuous predictors, model fitting, internal and external validation, performance measures, reporting, and model presentation. Our work builds on initiatives to improve diagnostic and prognostic clinical research, including the PROGnosis RESearch Strategy (PROGRESS) series of papers and textbook and the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) statement.

Tanulmányomban a hálózatkutatás eszköztárával tárom fel a Budapesti Értéktőzsdén a 2020-ban kibocsátóként jelen lévő entitások tulajdonviszonyainak hálózatát, statikus módszerek, valamint exponential random graph modeling (ERGM) elemzés alapján. A hálózat pillanatkép-tipológiája és szimuláció alapú megragadása során nem pusztán a tőzsdén jelen levő kibocsátók közötti kapcsolathálózat kerül elemzésre, hanem a hálózathoz kapcsolódó, ám a tőzsdén nem jegyzett cégek tulajdonviszonyai is, így a tanulmány teljes egészében kezeli az értéktőzsdéhez kapcsolódó tulajdonosi hálózatot. A kutatás eredményeként pontos válasszal rendelkezünk a hálózat morfológiai tulajdonságáról, a centralitást meghatározó hálózati faktorokról, a hálózat hierarchiájáról, valamint a szimulációk segítségével a hálózat kialakulásáról. A tanulmány hozzásegíthet ahhoz, hogy tisztább képet kapjunk a tőzsdén jegyzett cégek kapcsolódási pontjairól, klasztereiről, amelyek későbbi longitudinális elemzésekhez adhatnak támpontot.
sistema de salud colombiano, reflexiones sobre su influencia en la salud de la población
Authors: Reina Bolaños Carlos Alberto
Published: September 2021

Los sistemas de salud son una respuesta social que se modifica y adapta según el momento y lugar en la historia; en la medida que las sociedades se complejizan, estos encuentran nuevos desafíos. Conocer este panorama facilita su interpretación. Este artículo presenta una reflexión que parte de reconocer los principales avances y limitaciones del sistema de salud colombiano, para ampliar el panorama frente a sus posibilidades y necesidades de configuración. Se analizan elementos sociopolíticos y económicos de contexto y se examinan los principales indicadores de salud usados para reflejar la manera como los sistemas de salud responden a la protección de la población. El Sistema General de Seguridad Social en Salud, creado a través de la Ley 100 de 1993, nació en el contexto del desmonte de los Estados de bienestar y el fortalecimiento del neoliberalismo. Con este se han logrando avances en el acceso a los servicios de salud de la población en mayores condiciones de pobreza, sin embargo, se continúan presentando brechas e inequidades. La Terapia Ocupacional no es ajena a estas cuestiones, sus acciones deben propender por el cierre de tales brechas e inequidades sociales.

Objetivo: Comparar a Técnica Laparoscópica Totalmente Extraperitoneal (TEP) e a Técnica Laparoscópica Transabdominal Pré-peritoneal (TAPP) para a correção de hérnias inguinais. Métodos: Buscou-se avaliar as melhores circunstâncias para a utilização de cada uma. Realizada revisão integrativa nos bancos de dados PubMed, SciELO, LILACS e UpToDate, com os descritores DeCS: ''inguinal hernia’’ AND ‘'laparoscopy'' AND ‘'TEP'' AND ‘'TAPP'', e seus equivalentes em português. Resultados: As diferenças entre os resultados finais e as complicações não apresentaram grande divergência estatística. A TEP demonstrou redução da dor pós-operatória e menor tempo de internação hospitalar, mas apresenta curva de aprendizado mais longa e espaço de abordagem restrito, fatores que a tornam mais difícil. Apresentou também risco aumentado de lesões vasculares e maior incidência de complicações pós-operatórias. Já a TAPP, demonstrou facilidade no aprendizado, porém evoluiu com maiores riscos de aderências intestinais à tela, de lesões viscerais durante a entrada transabdominal e de dor no pós-operatório. Considerações finais: Não há diferença significativa entre as técnicas quanto a incidência de complicações pós-operatórias, a recorrência de reabordagem e o impacto na qualidade de vida dos pacientes. A decisão da melhor abordagem deverá ficar a critério do cirurgião e do serviço.
Spontaneous spinal cerebrospinal fluid venous-fistula treated with transvenous embolization: A case report
Authors: Aljuboori Zaid , McGrath Margaret , Essibayi Muhammed Amir , Zaidi Saif , Hallam Danial , Ghodke Basavaraj
Published: September 2021

Background:

Spinal cerebrospinal fluid venous fistula (CVF) is a recognized cause of chronic positional headache and spontaneous intracranial hypotension (SIH). It occurs due to an aberrant connection formed between the spinal subarachnoid space and an adjacent spinal epidural vein. The diagnosis of CVF can be difficult to establish but can be documented utilizing advanced imaging techniques (e.g., enhanced MR myelography/digital subtraction myelography). Their treatment involves surgical ligation of the involved nerve root, imaging-guided epidural blood patching, and/or endovascular embolization. Here, we report a 40-year-old male who presented with a symptomatic lumbar CVF successfully treated with transvenous embolization.

Case Description:

A 40-year-old male presented with several months of positional headaches. The MRI of the brain showed diffuse pachymeningeal enhancement consistent with the diagnosis of SIH. Although the MR of the lumbar spine was unremarkable, the MR myelogram with digital subtraction imaging showed a CVF at the L2 level. Following transvenous embolization (i.e., through the Azygous vein), the patient’s symptoms fully resolved.

Conclusion:

Spinal CVF are rare and may cause chronic headaches and symptoms/signs of SIH. In this case, an MR myelogram with digital subtraction images demonstrated the anomalous connection between the spinal subarachnoid space and an adjacent spinal epidural vein at the L2 level. Although open surgical ablation of this connection may be feasible, less invasive techniques such as endovascular embolization should become the treatment of choice for the future management of CVF.

هدفت الدراسة إلى اختبار التأثير الوقائي للمستخلص الكحولي لأوراق نبات السلبين في مرض الكبد الدهني اللاكحولي المستحدث في الفئران البيض وتحديد بعض التغيرات الكيميائية الحيوية والنسيجية المرافقة لذلك. أجريت الدراسة على أربعين فأراً ذكراً، قسمت بالتساوي على أربع مجموعات، حقنت فئران المجموعة التجريبية الأولى (السيطرة) بالمحلول الفيزيولوجي NACL بتركيز (%0.9) لمدة 10 أسابيع، كما حقنت فئران المجموعة الثانية (داخل البريتوان) بجرعة واحدة من رابع كلوريد الكربون ccl4 (1مل/ كغ) لاستحداث التشحم، وتركت مدة (24) ساعة قبل العمل، كما حقنت فئران المجموعة الثالثة لمرة واحدة فقط بجرعة من ccl4 (1مل/ كغ) وبجرعات يومية من المستخلص الكحولي لأوراق نبات السلبين لمدة 10 أسابيع (250 ملغ/ كغ من وزن الجسم)، وحقنت فئران المجموعة الرابعة داخل الصفاق لمرة واحدة فقط بجرعة من ccl4 (1مل/ كغ) مع جرعات يومية من الأتورفاستاتين (250 ملغ/ كغ من وزن الجسم) لمدة 10 أسابيع. بينت نتائج الدراسة النسيجية لأكباد فئران المجموعة التجريبية الثانية ظهور تشحم واضح وصل في بعض الأحيان لدرجة التنخر (تموضع النواة في المحيط)، في حين أظهرت نتائج أكباد فئران المجموعتين الثالثة والرابعة تحسناً واضحاً في الخلية الكبدية بالمقارنة مع المجموعة الثانية، حيث كان التشحم بحدوده الدنيا (نواة طبيعية مع عدم وجود بؤر التهابية) وهذا ما يؤكد الدور الوقائي المهم لمستخلص أوراق السلبين بمكوناته الفعالة (إلى جانب الأتورفاستاتين) ضد مرض التشحم الكبدي اللاكحولي.

Published: October 2021

Scheduling of associated tasks in heterogeneous systems is very important to reduce the total completion time as heterogeneity and coherence introduce more complexity. Several studies have focused on studying task scheduling in homogeneous systems and some studies have been limited to scheduling in heterogeneous systems. In this paper, a new algorithm was created and a simulation of the proposed algorithm was designed and tested using a random schema generator. This algorithm showed better results than its predecessors in terms of schedule length ratio relative to heterogeneity factor and Communication to Computation Ratio factor.
