Sustainable low-field cardiovascular magnetic resonance in changing healthcare systems.

Cardiovascular disease continues to be a major burden facing healthcare systems worldwide. In the developed world, cardiovascular magnetic resonance (CMR) is a well-established non-invasive imaging modality in the diagnosis of cardiovascular disease. However, there is significant global inequality in availability and access to CMR due to its high cost, technical demands as well as existing disparities in healthcare and technical infrastructures across high-income and low-income countries. Recent renewed interest in low-field CMR has been spurred by the clinical need to provide sustainable imaging technology capable of yielding diagnosticquality images whilst also being tailored to the local populations and healthcare ecosystems. This review aims to evaluate the technical, practical and cost considerations of low field CMR whilst also exploring the key barriers to implementing sustainable MRI in both the developing and developed world

The Influence of national innovation system on university-industry research collaboration

University-Industry Research Collaboration (UIRC) is one of the key factors for continuous innovation. Existing literature argue that UIRC can be shaped by National Innovation System (NIS). However, empirical evidence that looks into factors of national innovation system that influence UIRC is still lacking. The main goal of this research was to propose a new framework based on system thinking theory by investigating the influence of national innovation system on university-industry research collaboration. To achieve this aim, data were collected from research centers at Electrical and Chemical Engineering Departments of five research universities in Malaysia. Data were analyzed quantitatively using Statistical Package for the Social Sciences (SPSS) and Partial Least Squares Structural Equation Modeling (PLS-SEM). Whereas, some qualitative data from top management of corresponding industries of research centers were analyzed using NVivo 11. Results from the study revealed that technological infrastructure system, financing system, intellectual property right system, the culture of innovation and education and skills system have some influence on UIRC. Besides that, R&D cooperation, financial support, trustworthy culture, contractual agreement, intellectual capital, knowledge sharing and communication played significant roles as reinforcing factors in the relationship between NIS and UIRC. This study pioneered the application of system thinking theory in university-industry link research. In terms of practical contribution, findings from the study may serve as a guideline for policymakers in formulating policies and strategies to strengthen the innovative capabilities of UIRC. The limitations of this study are the non-inclusions of Ministry of Higher Education (MOHE) and the Ministry of Science, Technology and Innovation (MOSTI) as significant respondents other than research universities and their collaborated industries. It is recommended that future framework development could be expanded by exploring further factors that might have more effects on UIRC

Antioxidant and DPPH-Scavenging Activities of Compounds and Ethanolic Extract of the Leaf and Twigs of Caesalpinia bonduc L. Roxb.

Antioxidant effects of ethanolic extract of Caesalpinia bonduc and its isolated bioactive compounds were evaluated in vitro. The compounds included two new cassanediterpenes, 1α,7α-diacetoxy-5α,6β-dihydroxyl-cass-14(15)-epoxy-16,12-olide (1)and 12α-ethoxyl-1α,14β-diacetoxy-2α,5α-dihydroxyl cass-13(15)-en-16,12-olide(2); and others, bonducellin (3), 7,4’-dihydroxy-3,11-dehydrohomoisoflavanone (4), daucosterol (5), luteolin (6), quercetin-3-methyl ether (7) and kaempferol-3-O-α-L-rhamnopyranosyl-(1Ç2)-β-D-xylopyranoside (8). The antioxidant properties of the extract and compounds were assessed by the measurement of the total phenolic content, ascorbic acid content, total antioxidant capacity and 1-1-diphenyl-2-picryl hydrazyl (DPPH) and hydrogen peroxide radicals scavenging activities.Compounds 3, 6, 7 and ethanolic extract had DPPH scavenging activities with IC50 values of 186, 75, 17 and 102 μg/ml respectively when compared to vitamin C with 15 μg/ml. On the other hand, no significant results were obtained for hydrogen peroxide radical. In addition, compound 7 has the highest phenolic content of 0.81±0.01 mg/ml of gallic acid equivalent while compound 8 showed the highest total antioxidant capacity with 254.31±3.54 and 199.82±2.78 μg/ml gallic and ascorbic acid equivalent respectively. Compound 4 and ethanolic extract showed a high ascorbic acid content of 2.26±0.01 and 6.78±0.03 mg/ml respectively.The results obtained showed the antioxidant activity of the ethanolic extract of C. bonduc and deduced that this activity was mediated by its isolated bioactive compounds
