ABSTRACT
INTRODUCTION@#Lifestyle activities, such as regular physical activity, are important for good metabolic health and the prevention of non-communicable diseases. Epidemiological studies highlight an increase in the proportion of overweight children in Singapore. A workgroup was formed to develop recommendations to encourage children and adolescents (aged 7-17 years) to adopt a holistic approach towards integrating beneficial activities within a daily 24-hour period for good metabolic and general health.@*METHODS@#The Grading of Recommendations Assessment, Development and Evaluation (GRADE) Evidence to Decision framework was employed to formulate the public health question, assess the evidence and draw conclusions for the guide. The evidence for international 24-hour movement guidelines, and guidelines for physical activity, sedentary behaviour, and sleep and eating habits were reviewed. An update of the literature review from August 2018 to end of September 2020 was conducted through an electronic search of Medline and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases.@*RESULTS@#Ten consensus statements were developed. The statements focused on the overall aim of achieving good metabolic health through integration of these activities and initiatives: light and moderate- to vigorous-intensity physical activity on a regular basis; muscle- and bone-strengthening activities; limiting sedentary behaviour; regular and adequate sleep; good eating habits and choosing nutritionally balanced foods and drinks; practise safety in exercise; and aiming to achieve more or all aforementioned recommendations for the best results.@*CONCLUSION@#This set of recommendations provides guidance to encourage Singapore children and adolescents to adopt health-beneficial activities within a 24-hour period.

To construct a new high effective genetic engineering strain which can express active PAL enzyme in Lactococcus lactis (L.L), and acquire better effect on curing hyperphenylalaninemia rats, Firstly translational fusion vector and transcriptional fusion vector were constructed in E. coli MC1061, and then PAL cDNA was transformed into L.L. Two kinds of high effect strain were compared with their enzyme activity and animal experiment was carried out. The results showed: (1) Two kinds of engineering L.L. were obtained and translational fusion strain has higher level enzyme activity. (2) The amount of transcinnamic aicd reach peak when induced for 6 hours. (3) The blood phe level of the treated rats was significantly reduced compared with non-treated rats when receiving fresh p(NZ8048-PAL)1/NZ9000. The engineering L.L(translational fusion strain) can significantly reduce the blood phe level of the hyperphenylalaninemia rats, which has more superiority than pMG36e-PAL/L. L.
