Introduction: Pteropine orthoreovirus (PRV) is an emerging zoonotic respiratory virus that has spilled over from bats to humans. Though initially found only in bats, further case studies have found viable virus in ill patients. Methodology: PubMed was queried with the keywords of Nelson Bay orthoreovirus OR Pteropine orthoreovirus OR Melaka orthoreovirus OR Kampar orthoreovirus, and returned 17 hits. Results: Based on prevalence studies, the presence of PRV has been reported in Malaysia and Vietnam, both developing countries. Other case reports also provide further evidence of the presence of PRV in the Southeast Asian region. Despite the absence of PRV in their home countries, travellers from Hong Kong and Japan to Indonesia have returned to their countries ill with this virus, indicating that local communities in Indonesia might be affected by this virus. Conclusions: This work aims to bring to light this emerging zoonotic respiratory virus circulating among developing countries in Southeast Asia. To improve the understanding of PRV of the medical and scientific community in the Southeast Asian region, this work introduces the general features of PRV, reports of imported PRV, prevalence, and clinical features of PRV. Gaps in knowledge about PRV have also been identified in this work, and we hope that future studies can be undertaken to improve our understanding of this virus.

In December 2015, the Association of Southeast Asian Nations (ASEAN) celebrated the official establishment of the ASEAN Community. Having emerged in 1967 as a regional grouping of developing countries with minimal shared interests—beyond the common concern of economic growth and national resilience, ASEAN now has established regional structures which have been vital in enhancing development and dialogue on a broad range of issues across the Southeast Asian region. Over the years, the institutional development at the regional level has been accompanied by various efforts to promote regional unity and identity. The more recent years have also displayed that the international community has been supporting these efforts for ASEAN unity and identity by showing greater recognition of ASEAN as an international actor in its own right, for example, through the establishment of numerous country delegations to ASEAN.

The need to enhance their economic relations with each other has long been felt by developing countries. However, their efforts in this regard have met with limited success. One of the reasons for this could be that not much serious work has been done to understand the complexities and possibilities of economic relations of developing countries. The complementarities which exist among the economies of these countries remain relatively unexplored. There is a lack of concrete policy proposals which developing countries may follow to achieve their often proclaimed objective of collective self-reliance. All this needs serious and rigorous research efforts. In this perspective, the present study can be considered as a step in the right direction. It examines trade and other economic relations of developing countries of two regions of Asia-South Asian countries and member countries of the Association of Southeast Asian Nations (ASEAN). The study also explores ways and means to improve economic relations among these countries

The Muslim Social Science Scholars’ Forum of ASEAN (Associationof Southeast Asian Nations) held its Second Meeting in Bangkok, Thailandfrom Mubrram 20-23, 1409lSeptember 1-4, 1988, under the auspices of theFoundation for Democracy and Development Studies. The theme for themeeting was “Muslim Scholars and Social Science Research,” aimed atdocumenting, discussing and analyzing the types of scholarship or researchthat have been done about Muslims in the Southeast Asian region, particularlywithin the ASEAN countries.A select group of Muslim social science scholars (together with someMuslim politicians) from the countries within ASEAN, except Brunei, wereinvited to the “Forum.” They included: Drs. Dawan Raharjo and NurcholisMajid, and Professor Moeslim (Indonesia), Drs. Surin Pitsuwan, SeneeMadmarn and Chaiwat (Thailand), Drs. Yusof Talib and Hussain Mutalib(Singapore), Professors Taib Osman and Wan Hashim and Umar Farouq(Malaysia), and Drs. Carmen Abubakar, Madale and Mastura (Philippines).All participants were either presenters of papers or discussants.Throughout the four-day deliberations, participants discussed the typesof studies and research that have been the focus of scholars studying Muslimcommunities in the ASEAN region. Some titles of papers included: “MuslimStudies in the Phillipines;” “Social Science Research in Thailand;” and “SocialScience Research in Malaysia: the Case of Islamic Resurgence.”Given the “closed-door” ‘nature of the meeting (participation was byinvitation only), there was adequate time for a more intensive, frank andthorough discussions of the papers. Problems and issues were aired and posed,and alternative options offered by participants. For every paper, there wasa discussant; hence, the issues that came out of the papers managed to beseen, discussed and appreciated from a more complete and balancedperspective.By and large, the Bangkok meeting was a successful one. Theapproximately twenty participants were generally pleased with the high qualityof papers presented and the sense of brotherhood that prevailed. The warmhospitality of the hosts from Thailand was also appreciated ...

Abstract Objectives To evaluate the efficacy, defined as achieving target serum urate <6.0 mg/dl, and safety of urate-lowering therapies (ULT) for people with gout and CKD stages 3–5. Methods PubMed, The Cochrane Library, and EMBASE, were searched from 1 January 1959 to 31 January 2018 for studies that enrolled people with gout, who had an estimated glomerular filtration rate (eGFR) or creatinine clearance (CrCl) of < 60 mL/min, and exposure to allopurinol, febuxostat, probenecid, benzbromarone, lesinurad or pegloticase. All study designs other than case reports were included, except for people on dialysis, for which we did include case reports. Results There were 36 reports with an analysis of efficacy and/or safety based upon renal function – allopurinol (n = 12), febuxostat (n = 10), probenecid (n = 3), benzbromarone (n = 5), lesinurad (n = 5), and pegloticase (n = 1). There were 108 reports that involved people with gout and renal impairment but did not contain any analysis on efficacy and/or safety based upon renal function – allopurinol (n = 84), febuxostat (n = 14), benzbromarone (n = 1), lesinurad (n = 3), and pegloticase (n = 6). Most studies excluded people with more severe degrees of renal impairment (eGFR or CrCl of < 30mL/min). For allopurinol in particular, there was significant variability in the dose of drug used, and efficacy in terms of urate lowering, across all levels of renal impairment. Conclusion There is a lack of evidence regarding efficacy and/or safety of currently used ULT according to different levels of renal function. Future studies should include patients with CKD and should report study outcomes stratified by renal function.

Coronavirus disease (COVID-19) was first observed in Wuhan, Hubei Province (China) in December 2019, resulting in an acute respiratory syndrome. Only later was COVID-19 considered a public health emergency of international concern and, on 11 March 2020, the WHO classified it as pandemic. Despite being a respiratory virus, the clinical manifestations are also characterized by cardiological involvement, especially in patients suffering from previous comorbidities such as hypertension and diabetes mellitus, its complications being potentially serious or fatal. Despite the efforts made by the scientific community to identify pathophysiological mechanisms, they still remain unclear. A fundamental role is played by the angiotensin 2 converting enzyme, known for its effects at the cardiovascular level and for its involvement in COVID-19 pathogenesis. The goal of this paper was to highlight the mechanisms and knowledge related to cardiovascular involvement during the first pandemic phase, as well as to emphasize the main cardiological complications in infected patients.

AbstractThe insect order Phasmatodea is known for large slender insects masquerading as twigs or bark. In contrast to these so-called stick insects, the subordinated clade of leaf insects (Phylliidae) are dorso-ventrally flattened and therefore resemble leaves in a unique way. Here we show that the origin of extant leaf insects lies in the Australasian/Pacific region with subsequent dispersal westwards to mainland Asia and colonisation of most Southeast Asian landmasses. We further hypothesise that the clade originated in the Early Eocene after the emergence of angiosperm-dominated rainforests. The genus Phyllium to which most of the ~100 described species pertain is recovered as paraphyletic and its three non-nominate subgenera are recovered as distinct, monophyletic groups and are consequently elevated to genus rank. This first phylogeny covering all major phylliid groups provides the basis for future studies on their taxonomy and a framework to unveil more of their cryptic and underestimated diversity.

The present article describes an experimental study towards the examination of human visual behavior during the observation of unmanned aerial vehicles (UAVs) videos. Experimental performance is based on the collection and the quantitative & qualitative analysis of eye tracking data. The results highlight that UAV flight altitude serves as a dominant specification that affects the visual attention process, while the presence of sky in the video background seems to be the less affecting factor in this procedure. Additionally, the main surrounding environment, the main size of the observed object as well as the main perceived angle between UAV’s flight plain and ground appear to have an equivalent influence in observers’ visual reaction during the exploration of such stimuli. Moreover, the provided heatmap visualizations indicate the most salient locations in the used UAVs videos. All produced data (raw gaze data, fixation and saccade events, and heatmap visualizations) are freely distributed to the scientific community as a new dataset (EyeTrackUAV) that can be served as an objective ground truth in future studies.
