Parkinson’s disease (PD) is the world’s second neurodegenerative disorder after Alzheimer’s dise-ase, and degeneration of dopaminergic neurons is the hallmark. This novel management approach for Parkinson’s disease with Stachytarpheta jamaic-ensis was to assess the role of leaf extract on the histological and morphological properties of the hippocampus and prefrontal cortex in Paraquat-induced Parkinson’s disease. Twenty-eight adult Wistar rats of both sexes (180 - 240g) were assigned to four groups: N,N′-dimethyl-4,4′-bipyridinium dichloride (Paraquat, P), Paraquat and Stachytarpheta jamaicensis (PSJ), only S. jamaicensis (SJ) and control (CTR). Animals were allowed water and food ad libitum throughout, and the weights were taken periodically. Parkinson’s-like disease was induced by intraperitoneal injection of 8.4 mg/kg body weight of Paraquat twice weekly for three weeks in the P and PSJ groups; The PSJ further received SJ aqueous leaf extract for another two weeks. Neurobehavioural assessment using Barnes maze for spatial learning and memory was carried out. Animals were sacrificed at the end of the experiment, and brain specimens were excised and processed for histological and biochemical analyses of the hippocampus and prefrontal cortex. The results showed that paraquat caused the degeneration of pyramidal and granular neurons, as well as dysfunctional output of the hippocampus and prefrontal cortex. There was a significant loss of dopaminergic neurons mainly in the P group. On the other hand, SJ leaf extract preserved most of the neurons. In conclusion, SJ leaf extract produced observable positive effects on the hippocampus and prefrontal cortex of the paraquat-induced Parkinson’s disease model.

Pain is a subjective experience with two inseparable components: sensory and emotional. The personal property of pain experience makes it difficult to manage and treat due to the influence of genetics, age, gender, spiritual beliefs, social-economic status, and cultural factors. Similarly, medical care methods partly control pain experience and regulate pain progression. Contrary to chronic pain, which is continuous and recurrent, acute pain is primarily due to trauma, acute medical conditions, or treatment. Whatever the case, both can cause mood disorders. The interplay between mood disorders and pain upholds a progressively significant bidirectional link, as mood disorders and pain are risk factors for each other. Depression and anxiety heighten pain perception or decrease pain tolerance. Acute or chronic pain can also increase the chances of mood dysregulation. Although depression and anxiety have a close relationship with acute pain, the interplay between depression and acute pain is more comprehensively studied. Most depressed patients present pain as their sole complaint in primary care practices, which unfortunately is overlooked by physicians. Howbeit, reports on experimentally induced pain perception in depressed patients are mixed, presenting both an amplified and reduced pain threshold and tolerance. Although there are less published data about pain and anxiety, the association is regular because increased anxiety equally increases pain perception while decreasing tolerance. The aim of this review was to elucidate more on the mechanisms delineating the interconnectivity of pain and mood disorders.
Malignant Hyperthermia and Ryanodine Receptor Type 1 Gene (RyR1) Mutation in a Family in Singapore

Published: July 2022

Introduction: Sporadic clinical episodes of malignant hyperthermia (MH) that develop during general anaesthesia (GA) have been reported in Singapore. However, there is no published local report of a confirmed case of MH susceptibility (MHS) by skeletal muscle contracture tests and/or molecular tests. Materials and Methods: We report 2 patients from an extended family who developed signs of clinical MH while under GA. The MH episodes were successfully treated with intravenous dantrolene sodium. Sequence analysis of the entire Ryanodine Receptor Type 1 (RyR1) coding gene was carried out in an index patient. Results: The index patient was found to carry a c.7373G>A (p.Arg2458His) mutation in exon 46. This particular mutation satisfies the criteria for a MHS causative mutation. Hence, the index patient was considered to be MHS and did not need to undergo further muscle contracture testing. The same mutation was also found in 3 other members of his extended family. Conclusion: This is the first report of a Singaporean family with at least 4 members carrying a MH-causative mutation in RyR1 gene. This report serves to highlight the existence of the putative gene for MH in Singapore, and the need for clinical vigilance during anaesthesia involving the use of triggering agents.

Routine Staging Using Chest Computed Tomography in Workup of Treatment-Naïve Hepatocellular Carcinoma Prior to Locoregional Therapy: Is There a Need?
Authors: Leong Po Wey , Pua Uei , Lim Kian Soon
Published: July 2022

Introduction: The lung is the most common site of distal metastasis in patients with hepatocellular carcinoma (HCC), as seen in more than half of patients with extrahepatic disease. The incidence of pulmonary metastasis in all patients with HCC, however, remains low (between 4.5% to 20%). Their presence, nevertheless, contraindicates curative locoregional therapies. The role of staging chest computed tomography (CT) before locoregional treatment is not well defined. This study aimed to assess the utility of pre-treatment chest CT prior to locoregional therapy. Materials and Methods: Retrospective review of continuous cases of treatment-naïve HCC referred for locoregional therapy from 2004 to 2013 was performed. Patients with pre-treatment chest CT were evaluated for the presence of pulmonary metastases. HCC features (size, numbers, vascular invasion, nodal status and bone metastases) were recorded. Univariate analysis and multivariate logistic regression were performed for significant association. Results: A total of 780 patients were reviewed, of which 135 received staging chest CT. Pulmonary metastases (n = 17, 12.6%), benign lesions (n = 41, 30.4%) and indeterminate lesions (n = 11, 8.1%) were detected. Among the indeterminate lesions, there were losses to follow-up (n = 2) and deaths within the study period (n = 3). All patients with pulmonary metastases were declined locoregional therapy. Univariate analysis showed statistical significant association between pulmonary metastases with the number of intrahepatic lesions (P <0.01), primary tumour size (P = 0.018) and presence of vascular invasion (P <0.01). On multivariate analysis, the number of intrahepatic lesions (OR: 9.7; 95% CI, 1.6 to 57.2; P = 0.012) and presence of both hepatic and portal venous invasions (OR: 11.8; 95% CI, 1.1 to 128.8; P = 0.043) were the 2 independent positive predictors of pulmonary metastases. Conclusion: The prevalence of pulmonary metastasis is low in HCC and our study does not support the routine use of staging chest CT in all treatment-naïve patients. It can, however, be considered in cases with multiple lesions or vascular invasion.

Reversible Causes in Cardiovascular Collapse at the Emergency Department Using
Ultrasonography (REVIVE-US)
Authors: Chua Mui Teng , Chan Gene WH , Kuan Win Sen
Published: July 2022

Introduction: Ultrasonographic evaluation of patients in cardiac arrest is currently not protocolised in the advanced cardiac life support (ACLS) algorithm. Potentially reversible causes may be identified using bedside ultrasonography that is ubiquitous in most emergency departments (EDs). This study aimed to evaluate the incidence of sonographically detectable reversible causes of cardiac arrest by incorporating an ultrasonography protocol into the ACLS algorithm. Secondary objectives include rates of survival to hospital admission, hospital discharge, and 30-day mortality. Materials and Methods: We conducted a prospective study using bedside ultrasonography to evaluate for potentially reversible causes in patients with cardiac arrest at the ED of National University Hospital, Singapore, regardless of the initial electrocardiogram rhythm. A standardised ultrasonography protocol was performed during the 10-second pulse check window. Results: Between June 2015 and April 2016, 104 patients were recruited, corresponding to 65% of all out-of-hospital cardiac arrest patients conveyed to the ED. Median age was 71 years (interquartile range, 55 to 80) and 71 (68.3%) patients were male. The most common rhythm on arrival was asystole (45.2%). Four (3.8%) patients had ultrasonographic findings suggestive of massive pulmonary embolism while 1 received intravenous thrombolysis and survived until discharge. Pericardial effusion without tamponade was detected in 4 (3.8%) patients and 6 (5.8%) patients had intra-abdominal free fluid. Twenty (19.2%) patients survived until admission, 2 of whom (1.9%) survived to discharge and beyond 30 days. Conclusion: Bedside ultrasonography can be safely incorporated into the ACLS protocol. Detection of any reversible causes may alter management and improve survival in selected patients.

The drying process of coffee (Coffea arabica) is important to achieve quality organoleptic characteristics. The objective of the study was to evaluate the effect of drying by means of an electromechanical system based on infrared on sensory quality in special coffees cup. For this, an electromechanical system was designed using infrared emitters that combines electromagnetic radiation with conventional convective heating. 75 coffee samples were collected at three (3) height levels. The samples underwent the traditional drying process and the electromechanical system, to later be evaluated by professional tasters under the SCAA (Specialty Coffee Association of America) scale. The samples dried with infrared at 12% humidity presented a cupping value of 82.93 for cup coffee with a smaller data dispersion than the traditional system that obtained 81.34, in addition the t-test of non-equivalent samples indicates that its value is significantly better (p<0.05). We concluded that the electromechanical system with infrared drying increased the sensory quality of coffee compared to traditional drying.

Published: July 2022

A modernização da cadeia produtiva do cupuaçuzeiro (Theobroma grandiflorum), espécie perene frutífera com ciclo de melhoramento longo, depende da adoção de eficientes estratégias de melhoramento e seleção. Os caracteres agronômicos da espécie geralmente envolvem medidas repetidas, necessitando determinar o número ótimo de safras para uma seleção genética acurada, bem como, estudar a adaptabilidade e estabilidade temporal dos híbridos, fundamentais para a seleção genética. Neste sentido, o emprego de métodos estatísticos adequados é imprescindível para o alcance de resultados críveis e úteis ao programa de melhoramento. Esta dissertação objetivou avaliar diferentes modelos e estratégias de seleção, visando a determinação do número ótimo de safras a serem avaliados (Capítulo 1) e da estrutura de covariância mais adequada (Capítulo 2), além da seleção genética de híbridos (ambos capítulos). Com este fim, uma população com 34 híbridos triplos de cupuaçuzeiro, delineada em blocos casualizados e com número variável de repetições, foi avaliada durante nove safras consecutivas quanto a produtividade e resistência à vassoura-de-bruxa. Os procedimentos estatísticos foram baseados em modelos lineares mistos. Em todos os cenários, a flexibilização das estruturas de (co)variância dos modelos proporcionaram resultados mais precisos. Três e duas safras foram suficientes para selecionar acuradamente considerando produtividade e resistência, respectivamente, quando o objetivo for recombinar. Para recomendação, nove safras fornecerão a acurácia necessária. Foram selecionados dez híbridos com bons índices de produtividade, adaptabilidade, estabilidade e resistência. Tais híbridos deverão ser incorporados ao programa de melhoramento e as matrizes destaques dentre as plantas referentes à tais híbridos serão selecionadas e empregadas em futuras hibridações e/ou ensaios de competição clonal.

The objective of this research work was to analyze the causes that generate desertion among students in the virtual modality in the Lambayeque region. The research is descriptive - propositive and quantitative. The population consisted of 510 students for the 2019 II cycle. The survey and interview were used to collect information. As a result, it was obtained that students withdraw in the first cycle and do not report formally. The reason is that they do not know ordo not adapt to the modality of studies, so the University makes an automatic reservation for them, to facilitate their return in a short time. The conclusion reached in this research was that this phenomenon does not have a single cause, but is multi-causal, which should be analyzed in-depth to know and propose solutions from the beginning of the studies, as well as not to neglect the student throughout their training process, creating strategies for them to have support, advice and continuous accompaniment.

Authors: İPEK Süleyman , MERMERDAŞ Kasım
Published: July 2022

In the present study, the influence of the crumb rubber utilization as fine aggregate on the engineering properties of fly ash-based geopolymer mortar was experimentally investigated. In this context, the natural sand used in the production of geopolymer mortars was substituted with the crumb rubber, which comes out in the course of applying the retreading process to the end-of-life tires, at the substitution levels of 10%, 20%, 30%, 40%, and 50% by volume of aggregate content. In this way, 6 different geopolymer mixtures, one of which was the control mixture, were designed and produced. Then, the effect of crumb rubber on the fresh-state properties like flowability and fresh unit weight and the hardened-state properties like dry unit weight, compressive and flexural strengths of geopolymer mortars were examined. Besides, the properties of crumb rubber such as grading, specific gravity, water absorption capacity, fineness modulus as well as surface texture and particle shapes were compared with that of the river sand. Moreover, the interfacial transition zone (ITZ) occurring between both natural sand and crumb rubber and geopolymer paste was viewed using the SEM images. The results obtained in the scope of this study showed that crumb rubber had no significant influence on the flowing capability of the geopolymer mortars; however, incorporation of crumb rubber and increasing its substitution level had important effects on the unit weight, strength characteristics and ITZ. Moreover, the photographic view of the mixtures revealed that the crumb rubber particles were well-distributed on the mortar cross-section, namely no bleeding and segregation problems were faced. As a consequence, the results obtained in the scope of this study showed that crumb rubber could be used in geopolymer mortar production, provided that it is at certain substitution levels.

The Qur'an as Kalāmullah is the greatest miracle that was revealed to the prophet Muhammad SAW to be used as a guide for all human life until the Day of Judgment. Therefore, Allah instituted a debilitating or i'jāz character by which he would reveal the incompetence of his opponents. However, from the time of the prophet until now, there have been opponents of the Qur'an or people who doubt its authenticity. For this reason, the scholars are very attentive in discussing the i'jāz al-Qur'an, among those who pay serious attention to this study is Mana' Khalil al-Qattan. Through research that is library research, it can be concluded that, according to Mana' Khalil al-Qattan, the miracles of the Qur'an lie in all its aspects, such as language, sharia, scientific values ​​and so on. While the level of miracles of the Qur'an is comprehensive, even if it is a single letter. In addition, al-Qattan highlights the three most important aspects of i'jāz al-Qur'an, namely i'jāz al-lughawy, al-i'jāz al-ilmy, and al-i'jāz al-tasyrī'i which will always exist forever.

In earlier the 20 century, the development of Dayah was supervised by the Dutch government. Nevertheless, Dayah still presented its authority through the idea, pattern, curriculum, and method of dynamic learning. As a result, it played a role as a good model to create Islamic tradition, learning community, and charismatic Islamic scholars. In general, they will transform their responsibility not only as a religious scholar but also as a statesman who dedicates themselves to political change in Aceh.

This study is about job satisfaction with special reference to staff of Benson Idahosa University and University of Benin. Demographic variables such as gender, age, educational qualification, family size, working experience, income and job status were examined to find out their relationship or otherwise with the dependent variable. Another objective was to find out the difference in the level of job satisfaction in the public and private tertiary institutions. The study sample consists of three hundred respondents drawn from across the two universities. A questionnaire instrument was used to gather the needed information and the analytical techniques employed include simple percentage, t-test and regression analysis. All tests were performed at the 0.05 level of statistical significance. The finding of the study suggests that job satisfaction was well above average in areas such as the type of leadership and sort of work, and was below average in terms of salary, community value, pressure they got from the job and participation in supervision. The results also show that the majority of Benson Idahosa University staff were generally dissatisfied with their work especially in terms of feeling of accomplishment, level of participation, the value the community places on their job, the prestige of the job, recognition from supervisors, current state of the department and their chances of getting promoted. Most members of staff of the University of Benin were satisfied with all aspects of their job except feeling of accomplishment; pressure from the job and the value the society places on their job. The study indicates clearly that a higher percentage of staff of University of Benin (62%) enjoy a higher level of job satisfaction compared to Benson Idahosa University (43%). The result of the study shows that job satisfaction is negatively related to family size and job experience but positively related to job status. Based on these findings, it is recommended that private school proprietors as well as the government should make adequate resources available to enable their employees attain maximum satisfaction.

Authors:   Accounting Doctoral School, Bucharest University of Economic Studies, Romania, Mititean Pompei
Published: July 2022

This paper aims to examine the impact of board’s characteristics on the financial performance of firms operating in the energy industry, during a certain and uncertain time. For this purpose, we chose four board’s characteristics: duality of the CEO, size of the board, the board meetings and board’s independence, which represent our independent variables. For measuring financial performance, we chose the Return of Assets (ROA) and Return of Equity (ROE) ratios. The data used was collected from Refinitiv Eikon database and includes a sample of 359 companies, for the period 2018-2021. The SPSS statistical program was used to run the regression model on the selected sample. This study provides mixed results on the impact on board’s characteristics on the financial performance of companies operating in the energy industry. During certain time, CEO duality and board’s meetings are negatively correlated with ROE, but positively correlated with ROA. The size and board’s independence negatively affect the financial performance of companies for both ROA and ROE before and during COVID-19. This article contributes to previous studies conducted on the link between corporate governance and firm financial performance, showing mixed results. The results obtained may help management companies to carry out their corporate governance.
Environmental Racism and the COVID-19 Pandemic
Authors: Kim Erin , Chakraborty Arijit
Published: July 2022

Exposure to air pollutants like ground-level ozone and particulate matter is closely associated with rates of COVID-19 mortality and transmission. Potential biological mechanisms connecting pollution with COVID-19 severity include overexpression of the ACE2 receptor, pollutants’ role as a carrier or transport vector for COVID-19, destruction of the cilia, and compromised immune response of the lungs. Thus, individuals with more long-term exposure to air pollution are much more susceptible to severe symptoms from COVID-19. Social disparities dramatically affect which populations are regularly exposed to air pollutants and therefore incur disproportionate rates of respiratory diseases. Environmental racism and racial segregation have been shown to be significantly and positively associated with exposure to air pollution from sources like car engines and power plants. This results in individuals of low socioeconomic status, people of color, and those living in low-income areas being often exposed to increased levels of air pollution, making them more likely to suffer greater tragedies from COVID-19 and respiratory diseases. The results of this study provide insight into the public policy work necessary to ameliorate health inequities resulting from environmental racism and to prevent worse outcomes from future pandemics.
