Title: EphrinB2 enhances angiogenesis and anastomosis of bioengineered prevascularized dental pulp construct
Aims: To reveal the role of ephrinB2 in angiogenesis during coculture of stem cells from apical papilla (SCAP) and human umbilical vein endothelial cells (HUVEC); and lead to enhance anastomoses between prevascularised dental pulp construct and host vasculature.
Methods: EphrinB2 gene expression in SCAP and HUVEC will be modified by transfection and RNA interference (RNAi). Modified SCAP and HUVEC will be cocultured in biomimetic extracellular matrix, and the number and the average length of sprouts will be examined. The phosphorylation of ephrinB2 and EphB4 in SCAP cocultured with HUVEC will be detected using western blot. Prevascularized SCAP/EphrinB2 and HUVEC will be seeded into root canal, and implanted into immunodeficient mice at the same time, SCAP/vector and HUVEC only will be used as control. Implants will be harvested at days-1,-2,-3,-5,-7 and the formation of new blood vessel will be detected using immunohistochemical technique.
Expected Results: 1. EphrinB2 plays a critical role in SCAP enrolment as pericyte-like cells and facilitate assembly with endothelial cells. 2. Overexpression of ephrinB2 in SCAP and HUVEC in pulp tissue regeneration will accelerate the formation of capillary networks.
Conclusion: EphrinB2 may play an important role in angiogenesis and in vivo anastomosis, and could be a new target molecule for improving angiogenesis during regenerative endodontic therapy.

This issue in brief, A ‘Freer’ Flow of Skilled Labour within ASEAN: Aspirations, Opportunities, and Challenges in 2015 and Beyond, explores how ASEAN Member States are taking steps toward better qualifications recognition to prevent the resulting waste of human capital, in response to the mounting evidence that migrants in the region lack the skills recognition required to put their knowledge and training to use in destination countries.
This issue in brief also examines Member States’ goals versus the challenges they face, as well as the opportunities the region could stand to lose now and in the future if these challenges remain unmet. Realities on the ground—including the fact that around 87 percent of intra-ASEAN migrants are low-skilled workers, the prevalence of irregular migration in the region, and the flow imbalances among states—could complicate realization of the AEC’s already limited aspirations, the authors note.
This issue in brief is the eleventh in a series by the Migration Policy Institute and the International Organization for Migration’s Regional Office for Asia and the Pacific that is focused on offering succinct insights on migration issues affecting the Asia-Pacific region today.

To raise the awareness on human rights, Oxford University Press have recently produced a map of pins indicating 50 key human rights international cases from around the world, http://blog.oup.com/2014/12/human-rights-awareness-month-case-map/, each with a brief description and a link to a free article or report on the case. This map provides a quick tour to these cases, highlighting trends and themes, including some positive and some negative. It showcases the variety of international, regional, and national mechanisms and fora for adjudicating human rights claims, and the range of rights that have been recognized.

Title: A randomized clinical trial on the effect of a chlorine dioxide spray on dental plaque and respiratory pathogens in institutionalized elders
Abstract: Long term care institutions face a formidable challenge with the projected increase in the population of dependent elders in the coming decades. Poorer oral health has been consistently observed amongst institutionalized elders compared to community-dwelling elders, and this has been attributed to a number of factors including compromised physical and mental capabilities, resulting in a general loss of functional independence. This is further compounded by a general lack of awareness and neglect of oral hygiene by nursing home staff, whom residents depend on for the majority of their daily selfcare. Absence of daily oral hygiene results in the build-up of dental plaque and allows the uninhibited growth of opportunistic bacteria, which have been shown to cause lower respiratory tract infections such as aspiration pneumonia, one of the most common infectious causes of death among institutionalized elders. While there is a general consensus that an antimicrobial agent should be used as part of an optimal daily oral hygiene regimen in institutionalized elders, agreement has yet be reached regarding the optimal agent and its method of application. Delivery of an antimicrobial agent as a mouthwash may be problematic for frail elders who may be mentally impaired and unable to follow instructions, or have swallowing impairments and at a risk for aspiration. The use of an oral spray has been shown to be effective in other patient groups, and may be more appropriate and applicable for institutionalized elders. While chlorhexidine serves as the gold standard for anti-plaque effectiveness, prolonged usage is contraindicated due to side effects which include tooth staining and calculus formation. Chlorine dioxide is an effective antimicrobial agent, and short term studies have suggested a comparable anti-plaque activity compared to chlorhexidine, as well as the absence of these side effects. We now propose to test the effectiveness of a chlorine dioxide spray against a chlorhexidine spray in the reduction of dental plaque, oral respiratory pathogens, and incidence of aspiration pneumonia amongst institutionalized elders. All participants will be expected to benefit from the administered interventions, and we hope to develop an optimal oral hygiene protocol which can easily be adopted at a low cost by nursing homes regionally in Hong Kong, and potentially worldwide.
