    All food scientists must utilize plants for their application as functional foods to reduce hypercholesterolemia incidence through diet. Canarium odontophyllum (dabai) is a novel source for new healthy oil and functional foods. In this work, we evaluate the hepatoprotective effects of supercritical carbon dioxide (SC-CO2) extracted dabai pulp oil (DPO) and defatted dabai pulp (DDP) against hypercholesterolemia elicited by a high-cholesterol diet in rats. Our results show that DPO and DDP supplementation exerted beneficial hypocholesterolemic effects against the high-cholesterol diet-fed rat. Nevertheless, supplementation with DDP revealed superior total cholesterol, low-density lipoprotein, and HMG-CoA reductase lowering efficacy (p < 0.05). Supplementation of either DPO or DDP did not significantly affect AST and ALT levels than normal rats (p > 0.05). Therefore, DDP and DPO are considered as having no toxicological significance. The histological section of rats treated with DPO and DDP showed improved steatosis in hepatocytes. HPLC analysis revealed that DPO and DDP contained syringic acid, which plays an important role in the beneficial effect. In conclusion, our results support the hypocholesterolemic and hepatoprotective effects of DPO and DDP in the hypercholesterolemic rats model.

    We conducted a cross-sectional study of Malay participants aged 40-80 years (n = 2,932) to examine the associations between polymorphisms at newly identified, lipid-associated loci with blood lipid levels and prevalent cardiovascular disease (CVD) in a Malay population in Asia. A polymorphism adjacent to the TRIB1 locus (rs17321515) was associated with elevated total cholesterol and LDL-cholesterol (LDL-C) after adjustment for age and sex (both P values <0.007) and with increased risk of coronary heart disease and CVD [odds ratio (OR) 1.23, 95% confidence interval (95% CI) 1.03-1.46; and OR 1.2, 95% CI 1.02-1.42, respectively] under an additive model of inheritance. In addition, using recessive models of inheritance, polymorphisms on chromosome 19 adjacent to the CILP2 and PBX4 loci (rs16996148) and on chromosome 1 at the GALNT2 locus (rs4846914) were associated with elevated HDL-C (P = 0.005) and lower LDL-C (P = 0.048), respectively. Although novel, the former is consistent with the association between this polymorphism and lower blood triglycerides observed in the initial studies conducted in populations of European ancestry. Neither showed statistically significant association with CVD. These observations should form the basis of further investigation to identify the causative polymorphisms at this locus, and also to understand the mechanistic roles that this protein may play in lipoprotein metabolism in Asians and other populations.

    PMID: 11472471 DOI: 10.1046/j.1464-5491.2001.00494.x
    AIMS: To define the prevalence of dyslipidaemia in young diabetic patients in Peninsular Malaysia and the contributory factors of dyslipidaemia in these subjects.

    METHODS: This is a cross-sectional study involving 848 young diabetic patients from seven different centres, with representation from the three main ethnic groups. Clinical history and physical examination was done and blood taken for HbA1c, fasting glucose, total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol and triglycerides.

    RESULTS: The overall lipids were suboptimal, worse in Type 2 diabetes mellitus (DM) patients compared with Type 1 DM patients. Of the Type 2 patients, 73.2% had total cholesterol > 5.20 mmol/l, 90.9% had LDL-cholesterol > 2.60 mmol/l, 52.6% had HDL-cholesterol < 1.15 mmol/l and 27.3% had serum triglycerides > 2.30 mmol/l. There were ethnic differences in the lipid levels with the Malays having the highest total cholesterol (mean 6.19 mmol/l), and the highest LDL-cholesterol (mean 4.16 mmol/l), while the Chinese had the highest HDL-cholesterol (geometric mean 1.24 mmol/l). Ethnicity was an important determinant of total, LDL- and HDL-cholesterol in Type 2 DM, and LDL- and HDL-cholesterol and triglycerides in Type 1 DM. Glycaemic control was an important determinant of total, LDL-cholesterol and triglycerides in both Type 1 and Type 2 DM. Waist-hip ratio (WHR) was an important determinant of HDL-cholesterol and triglycerides in both types of DM. Gender was an important determinant of HDL-cholesterol in Type 2 DM, but not in Type 1 DM. Socioeconomic factors and diabetes care facilities did not have any effect on the dyslipidaemia.

    CONCLUSIONS: The prevalence of dyslipidaemia was high especially in Type 2 DM patients. Ethnicity, glycaemic control, WHR, and gender were important determinants of dyslipidaemia in young diabetic patients. Diabet. Med. 18, 501-508 (2001)

    Curr Med Res Opin, 2008 Jul;24(7):1951-63.
    PMID: 18547466 DOI: 10.1185/03007990802138731
    BACKGROUND: Data on achieving National Cholesterol Education Program Adult Treatment Panel III (ATP III) goals in Asia are limited.

    OBJECTIVE: To examine treatment patterns, goal attainment, and factors influencing treatment among patients in 6 Asian countries who were taking statins.

    METHODS: A retrospective cohort study was conducted in China, Korea, Malaysia, Singapore, Taiwan, and Thailand, where 437 physicians (41% cardiologists) recruited adults with hypercholesterolemia newly initiated on statin monotherapy.

    RESULTS: Of 2622 patients meeting inclusion and exclusion criteria, approximately 66% had coronary heart disease (CHD)/diabetes mellitus, 24% had no CHD but > or =2 risk factors, and 10% had no CHD and <2 risk factors. Most patients ( approximately 90%) received statins at medium or lower equipotency doses. Across all cardiovascular risk categories, 48% of patients attained ATP III targets for low-density lipoprotein cholesterol (LDL-C), including 38% of those with CHD/diabetes (goal: <100 mg/dL), 62% of those without CHD but with > or =2 risk factors (goal: <130 mg/dL), and 81% of those without CHD and <2 risk factors (goal: <160 mg/dL). Most patients who achieved goals did so within the first 3 months. Increasing age (odds ratio (OR)=1.015 per 1-year increment; 95% confidence interval (CI)=1.005-1.206; p=0.0038) and initial statin potency (OR=2.253; 95% CI=1.364-3.722; p=0.0015) were directly associated with goal attainment, whereas increased cardiovascular risk (OR=0.085; 95% CI=0.053-0.134; p<0.0001 for CHD/diabetes mellitus at baseline compared with <2 risk factors,) and baseline LDL-C (OR=0.990; 95% CI=0.987-0.993); p<0.0001 per 1-mg/dL increment) were inversely associated with LDL-C goal achievement. Limitations of this study include potential differences in treatment settings and cardiovascular risk factors between different countries and centers. In addition, the effects on cholesterol goal achievement of concomitant changes in lifestyle were not assessed.

    CONCLUSION: LDL-C goal attainment is low in Asians, particularly those with CHD/diabetes. More effective patient monitoring, treatments, including combining regimens and dose titration, and adherence to these treatments along with therapeutic lifestyle counseling may facilitate goal attainment.

    Chin GS, Todo H, Kadhum WR, Hamid MA, Sugibayashi K
    Chem Pharm Bull (Tokyo), 2016;64(12):1666-1673.
    PMID: 27904075
    The current investigation evaluated the potential of proniosome as a carrier to enhance skin permeation and skin retention of a highly lipophilic compound, α-mangostin. α-Mangostin proniosomes were prepared using the coacervation phase seperation method. Upon hydration, α-mangostin loaded niosomes were characterized for size, polydispersity index (PDI), entrapment efficiency (EE) and ζ-potential. The in vitro permeation experiments with dermis-split Yucatan Micropig (YMP) skin revealed that proniosomes composed of Spans, soya lecithin and cholesterol were able to enhance the skin permeation of α-mangostin with a factor range from 1.8- to 8.0-fold as compared to the control suspension. Furthermore, incorporation of soya lecithin in the proniosomal formulation significantly enhanced the viable epidermis/dermis (VED) concentration of α-mangostin. All the proniosomal formulations (except for S20L) had significantly (p<0.05) enhanced deposition of α-mangostin in the VED layer with a factor range from 2.5- to 2.9-fold as compared to the control suspension. Since addition of Spans and soya lecithin in water improved the solubility of α-mangostin, this would be related to the enhancement of skin permeation and skin concentration of α-mangostin. The choice of non-ionic surfactant in proniosomes is an important factor governing the skin permeation and skin retention of α-mangostin. These results suggested that proniosomes can be utilized as a carrier for highly lipophilic compound like α-mangostin for topical application.

    Saim N, Osman R, Sari Abg Spian DR, Jaafar MZ, Juahir H, Abdullah MP, et al.
    Water Res, 2009 Dec;43(20):5023-30.
    PMID: 19896157 DOI: 10.1016/j.watres.2009.08.052
    Faecal sterols detection is a promising method for identifying sources of faecal pollution. In this study, faecal contamination in water samples from point source (sewage treatment plants, chicken farms, quail farms and horse stables) was extracted using the solid phase extraction (SPE) technique. Faecal sterols (coprostanol, cholesterol, stigmasterol, beta-sitosterol and stigmastanol) were selected as parameters to differentiate the source of faecal pollution. The results indicated that coprostanol, cholesterol and beta-sitosterol were the most significant parameters that can be used as source tracers for faecal contamination. Chemometric techniques, such as cluster analysis, principal component analysis and discriminant analysis were applied to the data set on faecal contamination in water from various pollution sources in order to validate the faecal sterols' profiles. Cluster analysis generated three clusters: coprostanol was in cluster 1, cholesterol and beta-sitosterol formed cluster 2, while cluster 3 contained stigmasterol and stigmastanol. Discriminant analysis suggested that coprostanol, cholesterol and beta-sitosterol were the most significant parameters to discriminate between the faecal pollution source. The use of chemometric techniques provides useful and promising indicators in tracing the source of faecal contamination.

  7. Comparison of the efficacy and level of adherence for morning versus evening versus before bedtime administration of simvastatin in hypercholesterolemic patients
    Heng WK, Ng YP, Ooi GS, Habshoh J, Nurazlin J, Nor Azah MN, et al.
    Med J Malaysia, 2019 12;74(6):477-482.
    PMID: 31929472
    BACKGROUND: Simvastatin is usually taken in the evening due to the circadian rhythm of hepatic cholesterol biosynthesis. The degree of reduction of low-density lipoprotein cholesterol (LDL-C) and the level of adherence to different administration time remained unknown in the Malaysian population. This study aims to investigate the effect of simvastatin on the percentage changes of lipid profile and the level of adherence to when simvastatin was instructed to be taken at different timing.

    METHODS: Nine primary care health clinics across Malaysia participated in this study. 147 statin-naive subjects were selected through convenient sampling and randomised into one of the three arms (after breakfast, after dinner or before bedtime). Differences on percentage reduction of LDL-C from baseline and level of adherence among the three groups at week-16 were compared. The main outcomes measured in this study were the percentage change of lipid parameters and the percentage of high-adherence (MMAS=8) at week-16.

    RESULTS: 59.2% of the patients were male. The mean age of the study population was 53.93± 10.85 years. Most of the patients were Malays (69.4%); followed by Indians (22.4%) and Chinese (8.2%). LDL-C decreased from 4.26 (Standard Deviation, SD1.01) to 2.36 (SD0.69)mmol/L at week-16 for patients taking simvastatin before bedtime; an absolute reduction of 44.95%.The differences of LDL-C percentage reduction between three arms were significantly different (p<0.001). The greatest LDL-C reduction was observed when simvastatin was taken before bedtime and revealed 56.2% patients with high-adherence at week-16.

    CONCLUSION: Simvastatin showed superior LDL-reduction and higher level of adherence when being instructed to be taken before bedtime.

  8. Fulltext The major allergen Der p 2 is a cholesterol binding protein
    Reginald K, Chew FT
    Sci Rep, 2019 02 07;9(1):1556.
    PMID: 30733527 DOI: 10.1038/s41598-018-38313-9
    Der p 2 is a major dust mite allergen and >80% of mite allergic individuals have specific IgE to this allergen. Although it is well characterized in terms of allergenicity, there is still some ambiguity in terms of its biological function. Three-dimensional structural analysis of Der p 2 and its close homologues indicate the presence of a hydrophobic cavity which can potentially bind to lipid molecules. In this study, we aimed to identify the potential ligand of Der p 2. Using a liposome pulldown assay, we show that recombinant Der p 2 binds to liposomes prepared with exogenous cholesterol in a dose dependent fashion. Next, an ELISA based assay using immobilized lipids was used to study binding specificities of other lipid molecules. Cholesterol was the preferred ligand of Der p 2 among 11 different lipids tested. Two homologues of Der p 2, Der f 2 and Der f 22 also bound to cholesterol. Further, using liquid chromatography-mass spectrometry (LC-MS), we confirmed that cholesterol is the natural ligand of Der p 2. Three amino acid residues of Der p 2, V104, V106 and V110 are possible cholesterol binding sites, as alanine mutations of these residues showed a significant decrease in binding (p cholesterol.

  9. Fulltext An exploratory study on risk factors for chronic non-communicable diseases among adolescents in Malaysia: overview of the Malaysian Health and Adolescents Longitudinal Research Team study (The MyHeART study)
    Hazreen MA, Su TT, Jalaludin MY, Dahlui M, Chinna K, Ismail M, et al.
    BMC Public Health, 2014;14 Suppl 3:S6.
    PMID: 25437068 DOI: 10.1186/1471-2458-14-S3-S6
    BACKGROUND: The National Health & Morbidity Survey (NHMS) IV (2011) observed that the prevalence of obese children aged less than 18 years in Malaysia is 6.1% compared to 5.4% overweight and obese in NHMS III (2006). As such, this observation is of public health importance as obesity is a forewarning risk factor for chronic diseases such as type-2 diabetes, cardiovascular diseases (CVD) and certain types of cancers. This MyHeART (Malaysian Health and Adolescents longitudinal Research Team) study aims to examine risk factors of non-communicable diseases (NCD) among adolescents.
    METHODS/DESIGN: The MyHeART study is longitudinal cohort study of 1361 schoolchildren (13-years old) attending 15 public secondary schools from the central (Kuala Lumpur and Selangor) and northern (Perak) regions of Peninsular Malaysia. The study used a stratified sampling design to select the study participants. Data collected at baseline included socio-economic, lifestyle (e.g. smoking, physical activity assessment, fitness assessment, seven-day diet history), and environmental information, anthropometric measurements, blood pressure, handgrip strength and bone mineral density. Blood samples for fasting blood glucose and lipid profiles, full blood count, renal profile, as well as bone profile and serum vitamin D were taken. This study cohort will be followed up again when participants turn 15, 17 and lastly, after a period of ten years (around the age of 27).
    RESULTS: Nine percent of the adolescents from this study were obese. More male participants smoked compared to female participants (15.4% vs. 4.7%). Adolescent males had higher fasting blood glucose but the female participants had lower high density lipoprotein (HDL-cholesterol) and higher low density lipoprotein (LDL-cholesterol). In addition, adolescents from the rural area had higher fasting blood glucose, diastolic blood pressure, total cholesterol and LDL-cholesterol.
    DISCUSSION: Our results demonstrated that adolescents from the rural area are at higher risk of NCDs compared to their urban counterpart. Tailor made public health interventions are highly recommended for adolescents as this may minimise the dreadful NCD burden in adulthood and health disparity between the rural and urban in the near future.

  10. Obesity indices and metabolic markers are related to hs-CRP and adiponectin levels in overweight and obese females
    Sanip Z, Ariffin FD, Al-Tahami BA, Sulaiman WA, Rasool AH
    Obes Res Clin Pract, 2013 Jul-Aug;7(4):e315-20.
    PMID: 24306161 DOI: 10.1016/j.orcp.2012.05.002
    Obese subjects had increased serum high sensitivity C-reactive protein (hs-CRP), decreased adiponectin levels, and impaired microvascular endothelial function compared to lean subjects. We investigated the relationships of serum hs-CRP, adiponectin and microvascular endothelial function with obesity indices and metabolic markers in overweight and obese female subjects. Anthropometric profile, body fat composition, biochemical analysis, serum hs-CRP and adiponectin levels, and microvascular endothelial function were measured in 91 female subjects. Microvascular endothelial function was determined using laser Doppler fluximetry and the process of iontophoresis. Mean age and body mass index (BMI) of subjects were 34.88 (7.87) years and 32.93 (4.82) kg/m(2). hs-CRP levels were positively correlated with weight, BMI, waist circumference, hip circumference, body fat and visceral fat. Adiponectin levels were positively correlated with insulin sensitivity index (HOMA-%S), and inversely correlated with waist hip ratio, triglyceride, fasting insulin and insulin resistance index (HOMA-IR). No relationship was seen between microvascular endothelial function and obesity indices, and metabolic markers. In overweight and obese female subjects, hs-CRP levels were correlated with obesity indices while adiponectin levels were inversely correlated with obesity indices and metabolic markers. No significant relationship was seen between microvascular endothelial function with obesity indices and metabolic markers including hs-CRP and adiponectin in female overweight and obese subjects.

  12. Fulltext Cardio-metabolic risk factors and prehypertension in persons without diabetes, hypertension, and cardiovascular disease
    Chiang PP, Lamoureux EL, Shankar A, Tai ES, Wong TY, Sabanayagam C
    BMC Public Health, 2013;13:730.
    PMID: 23919264 DOI: 10.1186/1471-2458-13-730
    BACKGROUND: Prehypertension has been shown to be an early risk factor of cardiovascular disease (CVD). We investigated the prevalence and pattern of cardiometabolic risk factors in prehypertension in three ethnic Asian populations in Singapore.
    METHODS: We examined data from Chinese (n=1177), Malay (n=774), and Indian (n=985) adults aged 40-80 years who participated in three independent population based studies conducted from 2004-2011 in Singapore who were free of diabetes, hypertension and previous CVD. Prehypertension was defined as systolic blood pressure (BP) 120-139 mm Hg or diastolic BP 80-89 mm Hg. Random blood glucose, glycated haemoglobin (HbA1c), body mass index (BMI), triglycerides, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol were examined as indicators of adverse cardiometabolic profile. The association between metabolic variables and prehypertension was examined using logistic regression models adjusting for potential confounders.
    RESULTS: The prevalence of prehypertension was 59.8% (Chinese), 68.9% (Malays) and 57.7% Indians. Higher levels of blood glucose, HbA1c and BMI were significantly associated with prehypertension in all three ethnic groups, odds ratio (95% confidence interval) of prehypertension in Chinese, Malays and Indians were: 1.42 (1.10, 1.83), 1.53 (1.05, 2.24), 1.49 (1.13, 1.98) for high-glucose; 3.50 (1.01, 12.18), 3.72 (1.29, 10.75), 2.79 (1.31, 5.94) for high-HbA1c; 1.86 (1.34, 2.56), 2.96 (2.10, 4.18), 1.68 (1.28, 2.20) for high-BMI. In addition, higher levels of LDL cholesterol in Chinese and higher levels of triglycerides were significantly associated with prehypertension. These associations persisted when metabolic variables were analysed as continuous variables.
    CONCLUSIONS: Higher levels of blood glucose, HbA1c and BMI were associated with prehypertension in all three ethnic groups in Singapore. Screening for prehypertension and lifestyle modifications could potentially reduce the burden of CVD in otherwise healthy Asian adults living in Singapore.

    BMC Fam Pract, 2012;13:97.
    PMID: 23046818 DOI: 10.1186/1471-2296-13-97
    BACKGROUND: To evaluate the efficacy of Counselling and Advisory Care for Health (COACH) programme in managing dyslipidaemia among primary care practices in Malaysia. This open-label, parallel, randomised controlled trial compared the COACH programme delivered by primary care physicians alone (PCP arm) and primary care physicians assisted by nurse educators (PCP-NE arm).
    METHODS: This was a multi-centre, open label, randomised trial of a disease management programme (COACH) among dyslipidaemic patients in 21 Malaysia primary care practices. The participating centres enrolled 297 treatment naïve subjects who had the primary diagnosis of dyslipidaemia; 149 were randomised to the COACH programme delivered by primary care physicians assisted by nurse educators (PCP-NE) and 148 to care provided by primary care physicians (PCP) alone. The primary efficacy endpoint was the mean percentage change from baseline LDL-C at week 24 between the 2 study arms. Secondary endpoints included mean percentage change from baseline of lipid profile (TC, LDL-C, HDL-C, TG, TC: HDL ratio), Framingham Cardiovascular Health Risk Score and absolute risk change from baseline in blood pressure parameters at week 24. The study also assessed the sustainability of programme efficacy at week 36.
    RESULTS: Both study arms demonstrated improvement in LDL-C from baseline. The least squares (LS) mean change from baseline LDL-C were -30.09% and -27.54% for PCP-NE and PCP respectively. The difference in mean change between groups was 2.55% (p=0.288), with a greater change seen in the PCP-NE arm. Similar observations were made between the study groups in relation to total cholesterol change at week 24. Significant difference in percentage change from baseline of HDL-C were observed between the PCP-NE and PCP groups, 3.01%, 95% CI 0.12-5.90, p=0.041, at week 24. There was no significant difference in lipid outcomes between 2 study groups at week 36 (12 weeks after the programme had ended).
    CONCLUSION: Patients who received coaching and advice from primary care physicians (with or without the assistance by nurse educators) showed improvement in LDL-cholesterol. Disease management services delivered by PCP-NE demonstrated a trend towards add-on improvements in cholesterol control compared to care delivered by physicians alone; however, the improvements were not maintained when the services were withdrawn.

    Brown rice is unpolished rice with immeasurable benefits for human health. Brown rice (BR) and pre-germinated brown rice (PGBR) are known to contain various functional compounds such as gamma-oryzanol, dietary fibre and gamma-aminobutyric acid (GABA). In the present study, the experimental diets containing BR and PGBR (24, 48 h pre-germination) were used to investigate the influence of pre-germination time of brown rice on blood cholesterol in Sprague-Dawley male rats.

    Cholesterol and blood pressure (BP) can be effectively and safely lowered with statin drugs and BP-lowering drugs, reducing major cardiovascular (CV) events by 20%-30% within 5 years in high-risk individuals. However, there are limited data in lower-risk populations. The Heart Outcomes Prevention Evaluation-3 (HOPE-3) trial is evaluating whether cholesterol lowering with a statin drug, BP lowering with low doses of 2 antihypertensive agents, and their combination safely reduce major CV events in individuals at intermediate risk who have had no previous vascular events and have average cholesterol and BP levels.

    The main objective of this study was to use heating method (HM) to prepare liposome without employing any chemical solvent or detergent. Plackett-Burman design (PBD) was applied for the screening of significant process variables including the lecithin proportion, the cholesterol/lecithin ratio, the pH of solution for liposome preparation, the enzyme/lecithin ratio, the stirring time, the process temperature, the speed of stirrer, the ratio of stirrer to the tank diameter, the application of homogenization, the method of adding enzyme and centrifugation conditions on the encapsulation efficiency (EE %) of liposome and the activity of liposomal Flavourzyme (LAPU(-1)) (P

    In healthy Caucasian postmenopausal women, raloxifene increases bone mineral density (BMD), decreases biochemical markers of bone turnover, and lowers low-density lipoprotein (LDL) cholesterol, without effects on high-density lipoprotein (HDL) cholesterol and triglycerides. This randomized, double-blind study examines the effects of raloxifene 60 mg/d (n = 483) or placebo (n = 485) in healthy postmenopausal Asian women (mean age 57 yr) from Australia, Hong Kong, India, Indonesia, Malaysia, Pakistan, Philippines, Singapore, Taiwan, and Thailand. Serum osteocalcin, serum N-telopeptide, total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides were assessed at baseline and 6 months. Lumbar spine BMD was measured at baseline and 1 yr in 309 women from 4 countries. Clinical adverse events were recorded at each interim visit. At 6 months, raloxifene 60 mg/d significantly decreased osteocalcin, N-telopeptide, total cholesterol, and LDL cholesterol by medians of 15.9%, 14.6%, 5.3%, and 7.7%, respectively, from placebo. Changes in HDL cholesterol and triglycerides were similar between raloxifene and placebo. Raloxifene 60 mg/d increased mean lumbar spine BMD (1.9%) from placebo at 1 yr (P = 0.0003). The incidences of hot flashes (placebo 3.5%, raloxifene 5.6%, P = 0.12), and leg cramps (placebo 2.7%, raloxifene 4.3%, P = 0.16) were not different between groups. No case of venous thromboembolism was reported. The effects of raloxifene 60 mg/d on bone turnover, BMD, and serum lipids in healthy postmenopausal Asian women were similar to that previously reported in Caucasian women.

    In multiracial Singapore, the prevalence of coronary artery disease is highest in ethnic Indian and lowest in ethnic Chinese populations. Since susceptibility to coronary artery disease is closely associated with plasma lipid traits, we studied the cord blood lipid and apolipoprotein profiles of the three ethnic groups in Singapore to determine if ethnic differences in lipid profile are present at birth. The high-risk lipid traits of high LDL-cholesterol, triglycerides and apo B, low HDL-cholesterol and apo A-I were found to be highest in ethnic Indian and lowest in ethnic Chinese populations. This difference was concordant with the relative coronary mortality rates for their respective adult populations in Singapore.

    Aim: To synthesize niosomes co-encapsulating gemcitabine (GEM) and tocotrienols, and physicochemically characterize and evaluate the antipancreatic effects of the nanoformulation on Panc 10.05, SW 1990, AsPC-1 and BxPC-3 cells. Materials & methods: Niosomes-entrapping GEM and tocotrienols composed of Span 60, cholesterol and D-α-tocopheryl polyethylene glycol 1000 succinate were produced by Handjani-Vila and film hydration methods. Results: The film hydration produced vesicles measuring 161.9 ± 0.5 nm, approximately 50% smaller in size than Handjani-Vila method, with maximum entrapment efficiencies of 20.07 ± 0.22% for GEM and 34.52 ± 0.10% for tocotrienols. In Panc 10.05 cells, GEM's antiproliferative effect was enhanced 2.78-fold in combination with tocotrienols. Niosomes produced a significant ninefold enhancement in cytotoxicity of the combination, supported by significantly higher cellular uptake of GEM in the cells. Conclusion: This study is a proof of concept on the synthesis of dual-drug niosomes and their efficacy on pancreatic cancer cells in vitro.
