Isolation of phenolic compound from Lawsonia inermis and its prediction as anti-diabetic agent using molecular docking and molecular dynamic simulation.

High blood sugar is a defining feature of chronic disease, diabetes mellitus (DM). There are numerous commercially available medications for the treatment of DM. However, managing the patient's glucose levels remain a challenge because of the gradual reduction in beta-cell function and some side effects from the long-term use of various medications. Previous research has shown that the phenolic compound of henna plant (Lawsonia inermis L.) has the potential as anti-diabetic agent since it is able to suppress the digesting of α-amylase enzyme. In these studies, the plant' phenolic compounds have been isolated and characterized using UV, IR, NMR and LC-MS methods. Furthermore, the compound interaction into the active site of the α-amylase enzyme has been analyzed using molecular docking and molecular dynamics, as well as into α-glucosidase enzyme for predicting of the affinities. The results showed that isolated compound has the molecular formula of C15H10O6 with eleven degrees of unsaturation (DBE; double bond equivalence). The DBE value corresponds to the structure of the luteolin compound having an aromatic ring (8), a carbonyl group on the side chain (1) and a ketone ring with (2). The interaction study of the isolated compound with α-amylase and α-glucosidase enzyme using molecular docking compared to the positive control (acarbose) gave binding energy of -8.03 and -8.95 kcal/mol, respectively. The molecular dynamics simulation using the MM-PBSA method, complex stability based on solvent accessible surface area (SASA), root mean square deviation (RMSD), and root mean square fluctuation (RMSF) revealed that the compound has a high affinity for receptors. The characteristics of skin permeability, absorption, and distribution using ADME-Tox model were also well predicted. The results indicate that the phenolic compound isolated from L. inermis leaf was luteolin and it has the potential as an anti-diabetic agent.Communicated by Ramaswamy H. Sarma.

Effect of Eel Biscuit Supplementation on Height of Children with Stunting Aged 36-60 Months: A Pilot Study.

BACKGROUND: Stunting is a major health problem in developing countries. Animal-based supplements can increase the height of children with stunting. This study was aimed at determining the effect of eel biscuit supplementation on increase in the height of children with stunting aged 36-60 months. METHODS: A pilot study with pretest-post-test design. The study was conducted in two villages in the Priangan Region, West Java Province, Indonesia. The participants were divided into two groups: intervention group (10 supplemented eel biscuit pieces) and control group (biscuits from the government's biscuit programme). A total of 56 children aged 36-60 months with the height-for-age z-score of <-2 SD were recruited voluntarily for sampling. RESULTS: The initial height-for-age z-score of the intervention group was -3.45 SD and that of the control group was -3.11 SD. After 3 months of supplemented eel biscuit consumption, the height-for-age z-score of the intervention group changed to -2.52 SD and that of the control group changed to -2.51 SD. The average shift of the height-for-age z-score after 3 months of supplemented eel biscuit consumption was 0.93 SD in the intervention group and 0.6 SD in the control group. There were significant differences in delta and percent increase in the height-for-age z-score between both groups. CONCLUSIONS: Consumption of supplemented eel biscuits for 3 months increased the height-for-age z-score of children with stunting aged 36-60 months by 0.93 SD.

Effects of Selenium Supplementation on the Diabetic Condition Depend on the Baseline Selenium Status in KKAy Mice.

Oxidative stress in obesity leads to insulin resistance in type 2 diabetes. Some selenoproteins possess antioxidant properties, suggesting that selenium (Se) may protect against type 2 diabetes; however, evidence from epidemiological studies is contradictory. We hypothesized that Se status before supplementation (baseline) contributes to the supplementation outcome. This study aimed to clarify the influence of baseline Se status on the effect of Se supplementation on the diabetic condition. Six-week-old KKAy mice were fed a diet without supplemental Se or with 0.1 ppm Se in the form of L-selenomethionine (SeM) for 2 weeks to create low-Se and sufficient-Se baseline statuses, respectively. For the next 4 weeks, low-Se mice were given a SeM (0.5 ppm Se)-supplemented diet, and sufficient-Se mice were given either a SeM (0.5 ppm Se)- or sodium selenite (0.5 ppm Se)-supplemented diet; control groups continued on baseline diets. Serum Se concentrations, glutathione peroxidase (GPx) activities, adiponectin levels, glucose tolerance, and insulin sensitivity were analyzed. All mice became diabetic during the 2-week baseline induction period. At the end of the supplementation period, Se-receiving groups demonstrated significantly higher Se concentrations and GPx activities than their respective controls. Sufficient-Se mice receiving SeM had lower blood glucose levels and better insulin sensitivity than control and sodium selenite-receiving mice, whereas low-Se mice receiving SeM showed no such improvements compared with their controls. Our results suggest that Se supplementation in the form of SeM may help prevent type 2 diabetes aggravation in people taking the 55 µg/day Se recommended dietary allowance.

Factors influencing mother's participation in Posyandu for improving nutritional status of children under-five in Aceh Utara district, Aceh province, Indonesia.

BACKGROUND: Posyandu, or pos pelayanan terpadu (integrated service post), is a community-based activity for health services in Indonesia. According to the Indonesian Basic Health Survey, the prevalence of children under five in Indonesia who suffered from being underweight was 19.6 %. The wasting was 12.1 % and the stunting was 37.2 % in 2013, and these values have not changed greatly from 2007; much greater than the WHO targets of, less than 10 % underweight, 5 % wasting, and 20 % stunting. In Aceh were 26.6, 16.8, and 43.3 %, respectively. Also, the participation percentages of mothers to Posyandu was about 45 %, far below the national target of 100 %. In Aceh Province, the percentage was even lower (34 % in 2013). This study aimed to investigate the factors influencing participation of mothers in Posyandu. METHODS: This research used a cross-sectional design with sample of mothers who had children under five. They were chosen by multistage random sampling. Sample size was determined by the WHO formula. Face-to-face interviews were carried out using a questionnaire. The questionnaire consisted of items about socio-demographic characteristics, satisfaction with Posyandu services, attitude towards Posyandu benefits, and intention to attend Posyandu. The collected data were analyzed by using EZR (version 1.21). Fisher's exact test was performed to examine the associations between the socio-demographic factors, attitude, satisfaction, and intention covariates with participation. Logistic regression was used to describe the strength of the relationship between the predictor variables and participation. RESULTS: There were no significant differences in age, marital status, education level, occupation, family size, and distance to Posyandu between low participation group except for the monthly household income. Among the socio-demographic factors, only monthly household income had a significant association with the frequency of mothers' participation. Satisfaction, attitude, and intention were associated with participation. The logistic regression showed that monitoring the nutritional status of children under five was the main reason that mothers participated in Posyandu. Mothers who were satisfied with the Posyandu services were more likely to attend than those who were dissatisfied. Respondents with intention to participate in Posyandu every month were more likely to attend than those who did not intend to attend every month. Households with low income were more likely to participate in Posyandu than households with high income. CONCLUSION: Household income, mothers' satisfaction with Posyandu services, attitude towards Posyandu benefits and intention to attend Posyandu affect the participation frequency of the mother. In addition, monitoring the nutritional status of children under five was the main reason respondents attend Posyandu. Improving the quality of Posyandu services and providing qualified resources are needed to promote mothers' participation.
