    Imidazolinones as a persistent and active herbicides group have potential risks to non-target organisms in the environment. Biochar is a carbon-rich sorbent used as an amendment to change soil properties and its microbial communities effective on pesticides degradation rate. The present study was the first to compare empty fruit bunch (EFB) of oil palm and rice husk (RH) biomasses as biochar feedstock for remediation of imidazolinones-contaminated soils. Degradations of imazapic, imazapyr, and a mixture of them (Onduty®) was investigated in the presence of the optimized biochars in the soil during a 70-days incubation. Based on the results, the polar herbicides were resistant to hydrolysis degradation. Photolysis rates of the herbicides reduced significantly in the presence of the biochars in the soil. EFB biochar had greater effects due to its chemical compositions and surface functional groups. Photo-degradation of imazapyr was more affected by biochars amendment. The imidazolinones bio-degradation, however, accelerated significantly with the presence of EFB and RH biochars in soil with the greater effects of RH biochar. It was concluded that the application of the optimized EFB and RH biochars as an innovative sustainable strategy has the potential to decrease the persistence of the imidazolinones and minimize their environmental hazards.

    Analysis of herbicides sorption behavior in soil is critical in predicting their fate and possible harmful side effects in the environment. Application of polar imidazolinone herbicides is growing in tropical agricultural fields. Imidazolinones have high leaching potential and are persistent. In this study, adsorption-desorption of imazapic and imazapyr herbicides were evaluated in different types of Malaysian agricultural soils. Effects of soil parameters were also investigated on the soils' sorption capacities. The adsorption data fitted best to Freundlich isotherm (R2 > 0.991). The herbicides adsorptions were physical and spontaneous processes as ΔG values were negative and below 40 kJ/mol. The adsorption correlated positively with clay content, total organic carbon (TOC) content, and cation exchange capacity (CEC). There were strong negative correlations between hysteresis index and these factors indicating their importance in imidazolinones immobilization and, thus, their pollution reduction in the environment.

    Malays J Nutr, 1997;3(2):-.
    MyJurnal
    An assessment of the daily intake of major nutrients among 409 adults (males and females aged between 18-60 years, normal body mass index) residing in four regions in Malaysia was carried out as part of a major study on energy requirement. Subjects from both urban and rural areas completed a 3-day food record during the study. Mean energy intake among the men and women were 9.05 ± 2.21 MJ/day (2163 kcal/day) and 7.19 ± 1.60 MJ/day (1718 kcal/day) respectively, corresponding to 90% of the Malaysian RDA. A mean of 14% of the total energy was derived from protein, 23% from fat and 63% from carbohydrate. Energy intake amongst male subjects in the rural area (8.47 MJ/day, 2024 kcal) was significantly lower than their urban counterparts (9.52 MJ/day, 2275 kcal). There was no difference in mean energy intake in both the urban (7. 19 MJ/day, 1718 kcal) as well as rural women (7.16 MJ/day, 1711 kcal) corresponding to 86% of the RDA. The distribution of nutrients to the total energy intake amongst rural subjects were 13% for protein in both males and females, 65% for carbohydrate in males and 66% in females and 19% for fat in males and 21% for females. In the urban male and female subjects, the distribution of protein, carbohydrate and fat to the total energy intake were 14%, 55% and 29% and 30% respectively. The rural subjects showed a poorer mean intake of vitamins and minerals compared to the urban subjects. The diets of the male subjects in the rural area were deficient, less than two-third RDA in calcium, riboflavin and niacin. Calcium and iron intakes were less than two-third RDA in both the rural as well as the urban women. The rural women also had a poor intake of vitamin A and niacin. Overall, only protein and vitamin C intake met the RDA in most subjects from rural and urban areas.

    Achieving nutritional requirements for pregnant women in rural or suburban households while maintaining the intake of local and culture-specific foods can be difficult. Usage of a linear programming approach can effectively generate diet optimization models that incorporate local and culturally acceptable menus. This study aimed to determine whether a realistic and affordable diet that achieves recommended nutrient intakes for pregnant women could be formulated from locally available foods in Malaysia. A cross-sectional study was conducted to assess the dietary intake of 78 pregnant women using a 24-h dietary recall and a 3-day food record. A market survey was also carried out to estimate the cost of raw foods that are frequently consumed. All linear programming analyses were done using Excel Solver to generate optimal dietary patterns. Our findings showed that the menus designed from diet optimization models using locally available foods would improve dietary adequacy for the seven food groups based on the Malaysian Dietary Guidelines 2010 (MDG 2010) and the 14 nutrients based on Recommended Nutrient Intake 2017 (RNI 2017) in pregnant women. However, inadequacies remained for iron and niacin, indicating that these nutrients may require supplementation.

  5. Fulltext Ser-653-Asn substitution in the acetohydroxyacid synthase gene confers resistance in weedy rice to imidazolinone herbicides in Malaysia
    Ruzmi R, Ahmad-Hamdani MS, Mazlan N
    PLoS One, 2020;15(9):e0227397.
    PMID: 32925921 DOI: 10.1371/journal.pone.0227397
    The continuous and sole dependence on imidazolinone (IMI) herbicides for weedy rice control has led to the evolution of herbicide resistance in weedy rice populations across various countries growing IMI herbicide-resistant rice (IMI-rice), including Malaysia. A comprehensive study was conducted to elucidate occurrence, level, and mechanisms endowing resistance to IMI herbicides in putative resistant (R) weedy rice populations collected from three local Malaysian IMI-rice fields. Seed bioassay and whole-plant dose-response experiments were conducted using commercial IMI herbicides. Based on the resistance index (RI) quantification in both experiments, the cross-resistance pattern of R and susceptible (S) weedy rice populations and control rice varieties (IMI-rice variety MR220CL2 and non-IMI-rice variety MR219) to imazapic and imazapyr was determined. A molecular investigation was carried out by comparing the acetohydroxyacid synthase (AHAS) gene sequences of the R and S populations and the MR220CL2 and MR219 varieties. The AHAS gene sequences of R weedy rice were identical to those of MR220CL2, exhibiting a Ser-653-Asn substitution, which was absent in MR219 and S plants. In vitro assays were conducted using analytical grade IMI herbicides of imazapic (99.3%) and imazapyr (99.6%) at seven different concentrations. The results demonstrated that the AHAS enzyme extracted from the R populations and MR220CL2 was less sensitive to IMI herbicides than that from S and MR219, further supporting that IMI herbicide resistance was conferred by target-site mutation. In conclusion, IMI resistance in the selected populations of Malaysian weedy rice could be attributed to a Ser-653-Asn mutation that reduced the sensitivity of the target site to IMI herbicides. To our knowledge, this study is the first to show the resistance mechanism in weedy rice from Malaysian rice fields.

    Clin Interv Aging, 2019;14:1343-1352.
    PMID: 31413555 DOI: 10.2147/CIA.S211027
    PURPOSE: This study was aimed at determining the presence of cognitive frailty and its associated factors among community-dwelling older adults from the "LRGS-Towards Useful Aging (TUA)" longitudinal study.

    PATIENTS AND METHODS: The available data related to cognitive frailty among a sub-sample of older adults aged 60 years and above (n=815) from two states in Malaysia were analysed. In the LRGS-TUA study, a comprehensive interview-based questionnaire was administered to obtain the socio-demographic information of the participants, followed by assessments to examine the cognitive function, functional status, dietary intake, lifestyle, psychosocial status and biomarkers associated with cognitive frailty. The factors associated with cognitive frailty were assessed using a bivariate logistic regression (BLR).

    RESULTS: The majority of the older adults were categorized as robust (68.4%), followed by cognitively pre-frail (37.4%) and cognitively frail (2.2%). The data on the cognitively frail and pre-frail groups were combined for comparison with the robust group. A hierarchical BLR indicated that advancing age (OR=1.04, 95% CI:1.01-1.08, p<0.05) and depression (OR=1.49, 95% CI:1.34-1.65, p<0.001) scored lower on the Activity of Daily Living (ADL) scale (OR=0.98, 95% CI:0.96-0.99, p<0.05), while low social support (OR=0.98, 95% CI:0.97-0.99, p<0.05) and low niacin intake (OR=0.94, 95% CI:0.89-0.99, p<0.05) were found to be significant factors for cognitive frailty. Higher oxidative stress (MDA) and lower telomerase activity were also associated with cognitive frailty (p<0.05).

    CONCLUSION: Older age, a lower niacin intake, lack of social support, depression and lower functional status were identified as significant factors associated with cognitive frailty among older Malaysian adults. MDA and telomerase activity can be used as potential biomarkers for the identification of cognitive frailty.

  7. Fulltext Solubility enhancement studies on lurasidone hydrochloride using mixed hydrotropy
    Madan JR, Pawar KT, Dua K
    Int J Pharm Investig, 2015 Apr-Jun;5(2):114-20.
    PMID: 25838997 DOI: 10.4103/2230-973X.153390
    Low aqueous solubility is a major problem faced during formulation development of new drug molecules. Lurasidone HCl (LRD) is an antipsychotic agent specially used in the treatments of schizophrenia and is a good example of the problems associated with low aqueous solubility. Lurasidone is practically insoluble in water, has poor bioavailability and slow onset of action and therefore cannot be given in emergency clinical situations like schizophrenia. Hence, purpose of this research was to provide a fast dissolving oral dosage form of Lurasidone. This dosage form can provide quick onset of action by using the concept of mixed hydrotropy. Initially, solubility of LRD was determined individually in nicotinamide, sodium citrate, urea and sodium benzoate at concentration of 10, 20, 30 and 40% w/v solutions using purified water as a solvent. Highest solubility was obtained in 40% sodium benzoate solution. In order to decrease the individual hydrotrope concentration mixed hydrotropic agents were used. Highest solubility was obtained in 15:20:5 ratio of Nicotinamide + sodium benzoate + sodium citrate. This optimized combination was utilized in the preparation of solid dispersions by using distilled water as a solvent. Solid dispersions were evaluated for X-ray diffraction, differential scanning calorimetry and Fourier-transform infrared to show no drug-hydrotropes interaction has occurred. This solid dispersion was compressed to form fast dissolving tablets. Dissolution studies of prepared tablets were done using USP Type II apparatus. The batch L3 tablets show 88% cumulative drug release within 14 min and in vitro dispersion time was 32 min. It was concluded that the concept of mixed hydrotropic solid dispersion is novel, safe and cost-effective technique for enhancing the bioavailability of poorly water-soluble drugs. The miraculous enhancement in solubility and bioavailability of Lurasidone is clear indication of the potential of mixed hydrotropy to be used in future for other poorly water-soluble drugs in which low bioavailability is a major concern.

    PMID: 24394392
    A nutritional status study was carried out among a group of young Chinese adults, aged between 19 and 25, in Kuala Lumpur, Malaysia. Subjects comprised 108 young adults (55 women, 53 men) who were students at two institutes of higher learning. Physical characteristics were evaluated by anthropometric measurements while food intake was determined with a 3-day food record. Blood cholesterol and triglyceride were assessed using the Reflotron analyser. Birthweight was obtained from birth certificates or by proxy. The results showed that the mean body mass index (BMI) for men and women was 21.4 ± 3.3 and 20.0 ± 2.0, respectively, indicating normal weight. Further analysis of BMI classification demonstrated that 28% of men and 39% of women were underweight, 11% of men and 2% of women were overweight while 2% of men were obese. Mean waist-to-hip ratio showed that the subjects had a low risk of developing cardiovascular disease (0.72 ± 0.03 women; 0.81 ± 0.05 men). Mean energy intake was 8841 ± 1756 kJ per day for men and 6426 ± 1567 kJ per day for women. Closer analysis of energy intake of the subjects showed that 86% of men and 91% of women were consuming below the Malaysian recommendation for energy. Nutrients found to be deficient in at least one third of women were calcium, vitamin A, niacin and iron. Mean cholesterol intake in the diet was 278.7 ± 108.7 mg in men and 207.0 ± 82.5 mg in women and there was a significant difference between genders. Blood cholesterol and triglyceride levels were 3.88 ± 0.76 mmol/L and 1.08 ± 0.33 mmol/L, respectively in men, while these levels were lower in women, 3.87 ± 0.80 mmol/L for cholesterol and 0.99 ± 0.29 mmol/L for triglyceride. A general trend of higher mean blood cholesterol and triglyceride levels was shown in adults who were born with lower birthweights.

    Older adults quite often had an inadequate diet leading to micronutrient deficiencies and impaired immune response with subsequent development of degenerative diseases. This study aimed to determine the adequacy of energy and nutrient intake and its distribution among three aging groups i.e. successful aging (SA), usual aging (UA) and mild cognitive impairment (MCI). This is a cross-sectional study involving a large sample size (n = 2322) of older adults recruited through multistage random sampling from four states of Malaysia. An interview was conducted to measure dietary intake, neurocognitive status and functional status by using the Diet History Questionnaire (DHQ), Mini-Mental State Examination (MMSE), Rey Auditory Learning Test (RAVLT), Geriatric Depression Scale (GDS), Instrumental Activity of Daily Living (IADL) and Quality of Life Questionnaire. For comparison of dietary intake, a sub-sample of 173 respondents from each aging groups were matched and selected using a comparative cross-sectional approach. Women in SA group had the highest mean intake of vitamin A, calcium (p <0.05), vitamin C, riboflavin and iron (p<0.001). The same aging group also achieved the highest RNI percentage for the same nutrients. More than 80% of respondents for all aging groups did not met the recommended nutrient intake (RNI) for vitamin E, thiamin, niacin, folate, calcium and zinc. In women, MCI respondents were more likely to have an inadequate intake of vitamin A, C, riboflavin and iron followed by UA and SA. Inadequate vitamin E, niacin, folate and calcium were prevalent among all gender and aging groups. There is a need to further distinguish specific dietary patterns associated with these three aging groups to promote optimal nutrient intake for cognitive health.

    MyJurnal
    The objective of this study was to assess the nutritional status of children in FELDA Sungai Koyan, Pahang. Anthropometric measurements were taken from 105 children comprising of 62 boys and 43 girls aged 12 to 72 months. Food intake records from 84 of these children aged 4-6.9 years were obtained. Socio-economic factors which may influence nutritional status were also studied. The anthropometric assessment showed that 14.3% (n=15) of the children were underweight, 10.5% (n=11) stunted and 2.9% (n=3) wasted when compared with the NCHS Reference. It was also found that 28.6% (n=30) of the children had low mid arm circumference for age according to the Frisancho reference, indicating a low protein calorie reserve. The result of the dietary study showed that the intake of calories, calcium, niacin and thiamine were below the recommended daily allowances (RDA) for Malaysia. However, the intake of protein, iron, vitamin A, riboflavin and vitamin C were above the RDA levels. Foods most frequently taken were rice, fish, milk and meat. Vegetables and fruits were also often consumed by the children. Based on the Pearson correlation test, a significant relationship was shown between the nutritional status of the children (weight for age and height for age) with the mother’s educational level, and the number of children in the family. There was also a significant relationship between mother’s nutrition knowledge and the nutritional status of the children (weight for age). Inadequate calorie intake is one of the important factors involved in the causation of protein energy malnutrition. This problem is influenced by socio-economic factor such as low educational level and nutrition knowledge of mothers and large family size. Parents should be encouraged to participate in activities that enhance nutrition knowledge and promote good nutritional practices. FELDA is encouraged to organize more such activities.

    Dietary intakes and lifestyle habits during adolescence may predict the occurrence of obesity and other diet-related chronic diseases later in life. The purpose of this study was to determine dietary intake of adolescents in a fishing community in Tuaran District, Sabah. A total of 199 apparently healthy adolescents comprising 94 male and 105 female subjects were purposively selected for the study. The mean age of the subjects was 15.2 f 2.2 years with female subjects having a higher mean age of 15.7 f 2.4 years compared to the males (14.6 k1.8 years). The mean BMI of the subjects was 18.4 f 2.9 kg/m2 with females having a significantly higher BMI (18.9 f 2.8 kg/m2) than the males (17.8 f 3.0 kg/m2). Based on the WHO classification (WHO, 1995), 19.6% of the subjects could be classified as thin while 4.5% were at risk of overweight. Overall for both sexes, intake of energy and most nutrients were below the Malaysian recommended nutrient intake (RNI) levels for adolescents, with the exception of vitamin C and niacin. The male subjects showed higher mean intake for vitamin A, thiamine, niacin and vitamin C than the females. Calcium and iron intake ranked among the lowest levels, at 33.4% and 47.2% respectively of the RNI values for both sexes. The main sources of energy were rice, flour products and tubers while fish and seafood were the chief sources of protein. Majority of the subjects (84%) reported taking breakfast daily, which often consisted of fried noodles, fried banana, doughnuts and coffee. Consumption of snacks was popular and commonly consumed snacks were bread, biscuits, and fried banana. The present study revealed that 25.5% and 14.3% of the male and female adolescents respectively were thin, with majority of them consuming inadequate levels of energy and several key nutrients. The results underscore the need for adolescents to be targeted for nutrition and health education as they go through a period of marked physical, physiological and psychological changes.

    Adequate nutrition is important for mothers and their offspring during and after birth. This cross sectional study was conducted to determine nutritional status and nutritional knowledge of pregnant women from two selected private hospitals in Klang Valley, Malaysia. A total of 236 Malay pregnant women aged between 20 to 45 years old (mean age 31+5 years) were recruited through convenient sampling method. Socio-demographic data, nutritional knowledge and a 24-hours diet recall were obtained through a self-administered questionnaire. Anthropometric and haemoglobin data were obtained from the antenatal records in the respective hospitals. The percentages of participants who were underweight, normal, overweight and obese before pregnancy were 12.7%, 55.1%, 25.0% and 7.2% respectively. Among those who were obese before pregnancy, a total of 59.7% had inadequate weight gain, 24.6% gained adequate weight and 15.7% gained excessive gestational weight. About 33.5% of subjects were anaemic (Hb < 11.0g/dL). The mean daily energy intake of the participants was 1748 ± 526 kcal which was 76% of RNI. Calcium (73% of RNI), folic acid (36% of RNI), niacin (89% of RNI) and vitamin D (40% of RNI). The nutritional knowledge level of subjects was moderate (51.9 ± 13.8%). Lower monthly household income (p < 0.001), educational level (p < 0.001) and gestational stage (p < 0.05) of participants were associated with a lower nutritional knowledge level. Nutritional knowledge score was positively correlated with gestational weight gain (r = 0.166, p < 0.05) and haemoglobin level (r = 0.200, p < 0.05). Subjects who claimed practising food taboos had higher nutritional knowledge score (54.9 ± 12.5%) than those who did not (49.9 ± 14.4%)(p < 0.05). A comprehensive nutrition education should be integrated in the antenatal classes to improve nutritional status of pregnant women.

    Wan Dali WPE, Jan Mohamed HJ, Yusoff H
    Iran J Public Health, 2018 Aug;47(8):1098-1107.
    PMID: 30186781
    Background: The study examined the baseline findings of a controlled intervention study comprising anthropometric measurements, nutrient intakes, and physical activity among overweight or obese children in Kota Bharu, Kelantan, Malaysia.

    Methods: The study was completed in 2016 and the baseline data were gathered from four groups in a school-based randomized community trial among Year Five students from primary schools in Kota Bharu, Kelantan, Malaysia. Participants completed anthropometry assessment, three-day dietary record, and Physical Activity Questionnaire for Older Children (PAQ-C).

    Results: The prevalence of obesity was higher among the boys (52.5%). Mean energy intake was significantly higher among boys as compared to the girls (P=0.003). Twenty-five percent of the participants had exceeded the recommended nutrient intakes (RNI) of energy recommended. The calcium, thiamine, riboflavin, and niacin were also significantly higher among boys as compared to the girls (P<0.05). Boys also exhibited a significantly higher score on performance of physical activity (mean=2.68; SD=0.60) as compared to the girls (mean=2.38; SD=0.51) however it is still in the category of moderately active. Approximately 14.4% of children had a very low physical activity level.

    Conclusion: Overweight and obese boys had higher energy and fat intakes but were more physically active as compared to the girls. These findings might be useful in planning appropriate intervention strategies to be designed and delivered especially for this cohort.

    Malays J Nutr, 2005;11(1):1-21-.
    MyJurnal
    Traditionally, Chinese women adhere to special dietary practices during the month following childbirth. This paper discusses the dietary practices and food taboos practised by Chinese women in Kuala Lumpur. A total of 134 Chinese mothers of children below one year were recruited from three Maternal and Child Health Clinics and Maternity Hospital, Kuala Lumpur. Questionnaires and in-depth interviews were used to obtain information on socioeconomic background, dietary practices, food taboos and cooking methods during the confinement period. Food intake was assessed by multiple 24-hour dietary recall among 34 mothers during their confinement month (zuo yuezi). Body weight and height were measured, and body mass index calculated. Majority of the respondents had secondary school education (77.6%), household income between RM1001 and RM3000 (64%), and were homemakers (48.5%). The women were aged 18-39 years, and 68% were of normal weight. Most women (82%) practised 30 days of confinement, during which they adhered to special dietary practices. The diet was directed at attaining yin-yang (cold-hot) balance, whereby “hot” foods were most commonly used and “cold” foods were avoided. Ginger, rice wine and sesame seed oil, considered “hot” foods, were used in large amounts in the cooking. Rice, chicken and pork were also consumed in large amounts. Most vegetables and fruits were considered “cold” and were prohibited during confinement. Most mothers drank specially-prepared teas boiled from Chinese herbs. Mean energy intake was 19% below RNI, while mean protein intake was 93% above RNI (NCCFN, 2005). Mean intakes of thiamin, riboflavin and niacin were above 75% of RNI, while vitamins A and C were at half of RNI or less. Mean iron and calcium intakes were at 222% and 67% of RNI, respectively. It is concluded that most Chinese women in Kuala Lumpur do conform to special dietary practices during zuo yuezi.
