Essential Oil Blends: The Potential of Combined Use for Respiratory Tract Infections
Authors: Leigh-de Rapper Stephanie , Viljoen Alvaro , van Vuuren Sandy 
Published: December 2021

This study investigated the potential efficacy of 369 commercial essential oil combinations for antimicrobial, anti-toxic and anti-inflammatory activity with the aim of identifying synergy among essential oils commonly used in combination by aromatherapists for respiratory purposes. Essential oil combinations were assessed for their antimicrobial activities using a panel of Gram-positive, Gram-negative, and yeast strains associated with respiratory tract infections. The antimicrobial activity was measured by determining the minimal inhibitory concentration (MIC) of microbial growth. The fractional inhibitory concentration index (ΣFIC) was calculated to determine the antimicrobial interactions between the essential oils in the combination. The toxicity of the essential oil combinations was tested in vitro using the brine shrimp lethality assay, the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay on RAW 264.7 mouse macrophage cells and A549 lung cancer cell lines. In addition, an inflammatory response was evaluated measuring nitric oxide production. The essential oils, when in combination, demonstrated an increased antimicrobial effect, a reduction in toxicity and provided improved anti-inflammatory outcomes. Five distinct combinations [Cupressus sempervirens (cypress) in combination with Melaleuca alternifolia (tea tree), Hyssopus officinalis (hyssop) in combination with Rosmarinus officinalis (rosemary), Origanum marjorana (marjoram) in combination with M. alternifolia, Myrtus communis (myrtle) in combination with M. alternifolia and Origanum vulgare (origanum) in combination with M. alternifolia] were found to be the most promising, demonstrating antimicrobial activity, reduced cytotoxicity and improved anti-inflammatory effects. With the increased prevalence of respiratory tract infections and the growing antimicrobial resistance development associated with antimicrobial treatments, this study provides a promising complementary alternative for the appropriate use of a selection of essential oil combinations for use in the respiratory tract.

Published: December 2021

Recently, there have been urgent economic and scientific demands to decrease the use of chemical fungicides during the treatment of phytopathogens, due to their human health and environmental impacts. This study explored the biocontrol efficacy of novel and eco-friendly preen (uropygial) oil and endophytic Bacillus safensis in managing postharvest Botrytis grey mold in strawberry fruit. The preen oil (25 μL/mL) showed high antifungal activity against B. cinerea Str5 in terms of the reduction in the fungal radial growth (41.3%) and the fungal colony-forming units (28.6%) compared to the control. A new strain of Bacillus safensis B3 had a good potential to produce chitinase enzymes (3.69 ± 0.31 U/mL), hydrolytic lipase (10.65 ± 0.51 U/mL), and protease enzymes (13.28 ± 0.65 U/mL), which are responsible for the hydrolysis of the B. cinerea Str5 cell wall and, consequently, restrict fungal growth. The in vivo experiment on strawberry fruit showed that preen (uropygial) oil reduced the disease severity by 87.25%, while the endophytic bacteria B. safensis B3 reduced it by 86.52%. This study reports the efficiency of individually applied bioagents in the control of phytopathogenic fungi for the first time and, consequently, encourages their application as a new and innovative strategy for prospective agricultural technology and food safety.

BackgroundThere is little evidence about the relationship between aetiology, illness severity, and clinical course of respiratory tract infections (RTIs) in primary care. Understanding these associations would aid in the development of effective management strategies for these infections.AimTo investigate whether clinical presentation and illness course differ between RTIs where a viral pathogen was detected and those where a potential bacterial pathogen was found.Design and settingPost hoc analysis of data from a pragmatic randomised trial on the effects of oseltamivir in patients with flu-like illness in primary care (n = 3266) in 15 European countries.MethodPatient characteristics and their signs and symptoms of disease were registered at baseline. Nasopharyngeal (adults) or nasal and pharyngeal (children) swabs were taken for polymerase chain reaction analysis. Patients were followed up until 28 days after inclusion. Regression models and Kaplan–Meier curves were used to analyse the relationship between aetiology, clinical presentation at baseline, and course of disease including complications.ResultsExcept for a less prominent congested nose (odds ratio [OR] 0.55, 95% confidence interval [CI] = 0.35 to 0.86) and acute cough (OR 0.42, 95% CI = 0.27 to 0.65) in patients with flu-like illness in whom a possible bacterial pathogen was isolated, there were no clear clinical differences in presentations between those with a possible bacterial aetiology compared with those with a viral aetiology. Also, course of disease and complications were not related to aetiology.ConclusionGiven current available microbiological tests and antimicrobial treatments, and outside pandemics such as COVID-19, microbiological testing in primary care patients with flu-like illness seems to have limited value. A wait-and-see policy in most of these patients with flu-like illness seems the best option.
Investigating the Influence of Quality Factors on User Satisfaction with Summative Computer-based Assessment
Authors: Bello Hassan , Abdullah Nor Athiyah 
Published: December 2021

Computer-based assessment or e-assessment system is an e-learning system where information communication technology is utilized for examination activity, grading, and recording of responses of the examinees. It includes the entire assessment process from the examinees, teachers, institutions, examination agencies, and the public. E-assessment systems have been used extensively in educational and non-educational settings worldwide because of their significant impact on assessment to both the institutions and students. Electronic assessment systems have many significant advantages over conventional paper-pencil-based approaches, like reducing production cost, automatic marking, and fair grading. Other benefits include the ability to conduct adaptive testing, an increase in the frequency of assessment, a large number of people could be examined, low staff requirements during the assessment, and the ability to improve the quality of the evaluation. Text, images, audio, video, and interactive virtual environments in an e-assessment system are all feasible. Nevertheless, given all these advantages, some examinees expressed negative views about electronic assessment in our study due to fear or lack of familiarity with assessment technology and lack of information on e-assessment methods. Despite the increased adoption of e-assessment in higher education and organizations, the examinees' attitudes and opinions need to be studied to implement the system successfully. In an e-assessment environment, several factors account for the evaluation of the system quality. These factors can be categorized into three dimensions: technical, educational, and economical. However, based on literature reviewed, limited studies attempted to map these quality factors to determine user satisfaction with an e-assessment system. This scarcity of e-assessment satisfaction studies is the gap the study intends to fill. Furthermore, this study's findings would help provide practical and theoretical implications for educational institutions and organizations. This study is among the first application of the Delone and McLean information system success model to predict user satisfaction with computer-based assessment in a developing, African country.

Background Intraoperative rectal injury in prostatectomy patients is an uncommon but severe complication. Particular attention is paid to improving the results of healing damage to the anterior rectal wall during prostatectomy.Objective To study the morphological features of the parietal pelvic fascia and the rectal wall to substantiate the possibility of the formation of fascial duplication in the elimination of damage to the anterior rectal wall during prostatectomy.Material and Methods The authors carried out an intravital morphological analysis of the parietal pelvic fascia covering the levator rectum muscle and the anterior rectal wall in 10 men.Results The parietal pelvic fascia contains more powerful bundles of collagen fibers, which in certain areas are partially woven into the fibers of striated muscle tissue. The adventitia of the rectum is characterized by a looser arrangement of the interacting components of the formed connective and smooth muscle tissue. In the studied formations of the small pelvis, the thickness of collagen fibers separately and in the composition of bundles, as well as the cells of the differon and each fiber separately did not differ, which indicated the identity of their tinctorial properties in the compared zones.Conclusion Morphological analysis showed that when juxtaposing and touching the edges of the healing area of the surgical wound without tension, a stable and continuous scar of the fascial duplication is formed, which ensures reliable fusion of the stitched anatomical structures.

Two clinical cases of surgical treatment of cardiac right-chamber thromboembolism in pregnant women are described. Thromboembolism was diagnosed during a routine examination. In the first clinical case, considering the late pregnancy, a thromboembolectomy was performed under artificial circulation after surgical delivery.In the second case, thrombus removal from the right atrium was performed on a working heart, without interruption of pregnancy. The surgical and postsurgical period proceeded without any specific features and the patients were discharged from the hospital without any complications. These clinical cases show that it is possible to remove thrombus from the right heart chambers without the use of extracorporeal circulation, which is also safe for the mother and the fetus.

تأتي هذه المداخلة للتعريف بالإنتاج العلمي والرياضي لأحد علماء القرن الثامن الهجري/ 14 الميلادي، لتُضاف إلى سلسلة البحوث التي تنقب عن الإسهامات العلمية والثقافية والأدبية لعلماء الحضارة العربية الاسلامية ضمن نطاق الحضارة العالمية.
في البداية نُذكر بعصر الحسن النيسابوري- النصف الأول من القرن 7ه/13م والنصف الأول من القرن 8ه/ 14م- هذا القرن يعتبر من القرون الحاضرة في تاريخ الحضارة العربية الإسلامية كفترة غنية بالأحداث السياسية، الثقافية العلمية. هذا العصر صادف فترة الحكم المغولي في دار الإسلام. ونرى كيف تحول هؤلاء الغُُزاة بعد استقرارهم في البلاد الإسلامية إلى البناء والتشييد وتشجيع الحركة الأدبية والعلمية، من مثل تكَليف هولاكو (ت. 663 ه/ 1265م) لنصير الدين الطوسي (ت. 672ه/ 1274 م) ببناء مرصد فلكي، في مرغه عام 657ه/ 1259م.
في كنف هذه البيئة سنتحدث عن حياة ومؤلفات النيسابوري، مُركِّزين على إنتاجه الرياضياتي الموسوم ب: "الرسالة الشمسية في الحساب"
في الأخير سنحاول مقارنة هذا العمل مع بعض الأعمال المنجزة في هذا المجال من مثل: أعمال ابن البنا المُراكشي (ت. 721ه/ 1321 م) ونصير الدين الطوسي.
