    Plant phenolics are being increasingly consumed globally with limited scientific and clinical evidence pertaining to safety and efficacy. The oil palm fruit contains a cocktail of phenolics, and palm oil production results in high volumes of aqueous by-products enriched in phenolics and bioactives. Several lines of evidence from in vitro and in vivo animal studies confirmed that the aqueous extract enriched in phenolics and other bioactives collectively known as oil palm phenolics (OPP) is safe and has potent bioactivity. A phase one clinical trial was conducted to evaluate the safety and effects of OPP in healthy volunteers. In this single-blind trial, 25 healthy human volunteers were supplemented with 450 mg gallic acid equivalent (GAE)/day of OPP or control treatments for a 60-day period. Fasting blood and urine samples were collected at days 1, 30 and 60. Medical examination was performed during these trial interventions. All clinical biochemistry profiles observed throughout the control and OPP treatment period were in the normal range with no major adverse effect (AE) or serious adverse effect (SAE) observed. Additionally, OPP supplementation resulted in improvement of total cholesterol and LDL-C levels, compared to the control treatment. The outcomes support our previous observations that OPP is safe and may have a protective role in reducing cholesterol levels.

    Tiger milk mushroom (TMM; Lignosus rhinocerus) have been used for a long time by indigenous communities in South East Asia regions as traditional medicine for different ailments, including respiratory disorders. The beneficial effects of TMM have been proven through in vivo and in vitro models, but these effects have yet to be validated in a clinical study. In this study, the beneficial effects of TMM supplementation were investigated in 50 voluntary participants. Participants were required to take 300 mg of TMM twice daily for three months. Level of interleukin 1β (IL-1β), interleukin 8 (IL-8), immunoglobulin A (IgA), total antioxidant capacity, malondialdehyde (MDA), 3-nitrotyrosine (3-NT), 8-hydroxydeoxyguanosine (8-OHdG), pulmonary function and respiratory symptoms were assessed during baseline and monthly follow-up visits. Results demonstrated that supplementation of TMM significantly (p

  3. Fulltext Untargeted serum metabolites profiling in high-fat diet mice supplemented with enhanced palm tocotrienol-rich fraction using UHPLC-MS
    Goon DE, Ab-Rahim S, Mohd Sakri AH, Mazlan M, Tan JK, Abdul Aziz M, et al.
    Sci Rep, 2021 10 25;11(1):21001.

    Excessive high fat dietary intake promotes risk of developing non-alcoholic fatty liver disease (NAFLD) and predisposed with oxidative stress. Palm based tocotrienol-rich fraction (TRF) has been reported able to ameliorate oxidative stress but exhibited poor bioavailability. Thus, we investigated whether an enhanced formulation of TRF in combination with palm kernel oil (medium-chain triglycerides) (ETRF) could ameliorate the effect of high-fat diet (HFD) on leptin-deficient male mice. All the animals were divided into HFD only (HFD group), HFD supplemented with ETRF (ETRF group) and HFD supplemented with TRF (TRF group) and HFD supplemented with PKO (PKO group). After 6 weeks, sera were collected for untargeted metabolite profiling using UHPLC-Orbitrap MS. Univariate analysis unveiled alternation in metabolites for bile acids, amino acids, fatty acids, sphingolipids, and alkaloids. Bile acids, lysine, arachidonic acid, and sphingolipids were downregulated while xanthine and hypoxanthine were upregulated in TRF and ETRF group. The regulation of these metabolites suggests that ETRF may promote better fatty acid oxidation, reduce oxidative stress and pro-inflammatory metabolites and acts as anti-inflammatory in fatty liver compared to TRF. Metabolites regulated by ETRF also provide insight of its role in fatty liver. However, further investigation is warranted to identify the mechanisms involved.

  4. Fulltext Effect of palm-based tocotrienols and tocopherol mixture supplementation on platelet aggregation in subjects with metabolic syndrome: a randomised controlled trial
    Gan YL, Fu JY, Lai OM, Chew BH, Yuen KH, Teng KT, et al.
    Sci Rep, 2017 09 14;7(1):11542.
    PMID: 28912593 DOI: 10.1038/s41598-017-11813-w
    Tocotrienols, the unsaturated form of vitamin E, were reported to modulate platelet aggregation and thrombotic mechanisms in pre-clinical studies. Using a Food and Drug Administration (FDA)-approved cartridge-based measurement system, a randomised, double-blind, crossover and placebo-controlled trial involving 32 metabolic syndrome adults was conducted to investigate the effect of palm-based tocotrienols and tocopherol (PTT) mixture supplementation on platelet aggregation reactivity. The participants were supplemented with 200 mg (69% tocotrienols and 31% α-tocopherol) twice daily of PTT mixture or placebo capsules for 14 days in a random order. After 14 days, each intervention was accompanied by a postprandial study, in which participants consumed 200 mg PTT mixture or placebo capsule after a meal. Blood samples were collected on day 0, day 14 and during postprandial for the measurement of platelet aggregation reactivity. Subjects went through a 15-day washout period before commencement of subsequent intervention. Fasting platelet aggregation reactivity stimulated with adenosine diphosphate (ADP) did not show substantial changes after supplementation with PTT mixture compared to placebo (p = 0.393). Concomitantly, changes in postprandial platelet aggregation reactivity remained similar between PTT mixture and placebo interventions (p = 0.408). The results of this study highlight the lack of inhibitory effect on platelet aggregation after short-term supplementation of PTT mixture in participants with metabolic syndrome.

    PMID: 29085045 DOI: 10.1038/s41598-017-14765-3
    Spinal cord injury (SCI) occurs following different types of crushes. External and internal outcomes of SCI are including paralysis, cavity, and cyst formation. Effects of dietary derived antioxidants, such as palm vitamin E on central nervous system (CNS) encourage researchers to focus on the potential therapeutic benefits of antioxidant supplements. In the present study, experiments were carried out to evaluate the neuro-protective effect of the palm vitamin E on locomotor function and morphological damages induced SCI. Seventy-two male rats (Sprague-Dawley) were randomly divided into four groups: sham (laminectomy); control (supplemented with the palm vitamin E at a dose of 100 mg/kg/day); untreated-SCI (partial crush, 30-33% for 20 sec); treated-SCI (partial crush, 30-33% for 20 sec supplemented with the palm vitamin E at a dose of 100 mg/kg/day). The treatment with the palm vitamin E significantly improved the hind limb locomotor function, reduced the histopathological changes and the morphological damage in the spinal cord. Also, the palm vitamin E indicated a statistically significant decrease in the oxidative damage indicators, malondialdehyde (MDA) level and glutathione peroxidase (GPx) activity in the treated-SCI compared to the untreated-SCI.

    PMID: 28878245 DOI: 10.1038/s41598-017-09823-9
    Centella asiatica (L.) Urb. has been used as an herbal brain tonic for mental disorders and enhancing memory, but no review of the overall evidence of C. asiatica and cognitive function has been conducted. This study aims to determine the effects of C. asiatica on cognitive function and its related properties. The current systematic review includes five randomized controlled trials (RCTs) conducted to determine the effect of C. asiatica alone and six RCTs conducted to determine the effect of C. asiatica-containing products. Meta-analysis indicated that there are no significant differences in all cognitive function domains of C. asiatica when compared to placebo. However, it could improve mood by increasing alert scores [SMD: 0.71 (95% CI; 0.01 to 1.41); I2 = 30.5%] and decreasing anger scores at 1 hour after treatment [SMD: -0.81 (95%CI; -1.51 to -0.09); I2 = 36.6%]. None of the studies reported adverse effects of C. asiatica. In conclusion, there is not strong evidence to support the use of C. asiatica for cognitive function improvement in each cognitive domain. C. asiatica could improve alertness and relieve anger. However, some limitations should be aware including dose regimen, plant preparation, standardization, and product variation. Future well-designed clinical trials using suitable doses of standardized C. asiatica are still needed.

    PMID: 22382249
    To determine the medication prescribing patterns in hospitalized patients with chronic kidney disease (CKD) in a Malaysian hospital, we prospectively studied a cohort of 600 patients in two phases with 300 patients in each phase. The first phase was carried out from the beginning of February to the end of May 2007, and the second phase was from the beginning of March to the end of June 2008. Patients with CKD who had an estimated creatinine clearance ≤ 50 mL/min and were older than 18 years were included. A data collection form was used to collect data from the patients' medical records and chart review. All systemic medications prescribed during hospitalization were included. The patients were prescribed 5795 medications. During the first phase, the patients were prescribed 2814 medication orders of 176 different medications. The prescriptions were 2981 of 158 medications during the second phase. The mean number of medications in the first and second phases was 9.38 ± 3.63 and 9.94 ± 3.78 respectively (P-value = 0.066). The top five used medications were calcium carbonate, folic acid/vitamin B complex, metoprolol, lovastatin, and ferrous sulfate. The most commonly used medication classes were mineral supplements, vitamins, antianemic preparations, antibacterials, and beta-blocking agents. This study provides an overview of prescription practice in a cohort of hospitalized CKD patients and indicates possible areas of improvement in prescription practice.

    Due to antimicrobial resistance and the public health hazard of antibiotic growth promoters, there is a grave need to find potential alternatives for sustainable poultry production. Piper betle (PB) and Persicaria odorata (PO) are herbs, which have been reported for antimicrobial, antioxidant, and anti-inflammatory properties. The present study aimed to estimate the influence of different dose supplementation of Piper betle leaf meal (PBLM) and Persicaria odorata leaf meal (POLM) on growth performance, ileal digestibility and gut morphology of broilers chickens. A total of 210 one day-old broiler chicks were randomly grouped into 7 treatments, and each treatment group has 3 replicates (n = 10) with a total number of 30 chicks. The treatments included T1 control (basal diet (BD) with no supplementation), T2 (BD + 2 g/kg PBLM); T3 (BD + 4 g/kg PBLM), T4 (BD + 8 g/kg PBLM), T5 (BD + 2 g/kg POLM), T6 (BD + 4 g/kg POLM), T7 (BD + 8 g/kg POLM). Growth performance, gut morphology and ileal digestibility were measured. Except for T4 (8 g/kg PBLM), graded dose inclusion of PBLM and POLM increased (P

  10. Fulltext Impact of pH and butyric acid on butanol production during batch fermentation using a new local isolate of Clostridium acetobutylicum YM1
    Al-Shorgani NKN, Kalil MS, Yusoff WMW, Hamid AA
    Saudi J Biol Sci, 2018 Feb;25(2):339-348.
    PMID: 29472788 DOI: 10.1016/j.sjbs.2017.03.020
    The effect of pH and butyric acid supplementation on the production of butanol by a new local isolate of Clostridium acetobutylicum YM1 during batch culture fermentation was investigated. The results showed that pH had a significant effect on bacterial growth and butanol yield and productivity. The optimal initial pH that maximized butanol production was pH 6.0 ± 0.2. Controlled pH was found to be unsuitable for butanol production in strain YM1, while the uncontrolled pH condition with an initial pH of 6.0 ± 0.2 was suitable for bacterial growth, butanol yield and productivity. The maximum butanol concentration of 13.5 ± 1.42 g/L was obtained from cultures grown under the uncontrolled pH condition, resulting in a butanol yield (YP/
    S
    ) and productivity of 0.27 g/g and 0.188 g/L h, respectively. Supplementation of the pH-controlled cultures with 4.0 g/L butyric acid did not improve butanol production; however, supplementation of the uncontrolled pH cultures resulted in high butanol concentrations, yield and productivity (16.50 ± 0.8 g/L, 0.345 g/g and 0.163 g/L h, respectively). pH influenced the activity of NADH-dependent butanol dehydrogenase, with the highest activity obtained under the uncontrolled pH condition. This study revealed that pH is a very important factor in butanol fermentation by C. acetobutylicum YM1.

    The experiment was conducted to determine the feed intake and body weight (BW) change of Boer goats supplemented with a commercial concentrate pellet and combinations of concentrate and soya waste. Twelve male goats were divided into three groups. Each group was randomly allocated to each of the three treatment diets: Napier grass (Pennisetum purpureum) ad libitum and concentrate pellet at rate of 2.0% of BW, daily (T1); Napier grass ad libitum and concentrate pellet at rate of 1.4% of BW and soya waste at rate of 0.5% of BW, daily (T2) and Napier grass ad libitum and concentrate pellet at rate of 0.9% of BW and soya waste at rate of 0.5% of BW, daily (T3). The results indicated that supplementation of concentrate pellet together with soya waste (T2 or T3) significantly (p<0.05) decreased intakes of grass dry matter (DM), total DM and total crude protein compared to the solely concentrate pellet group (T1). However, BW gain was significantly (p<0.05) higher in T2 treatment compared with the T1 or T3 treatments. Supplementation of concentrate pellet with soya waste (T2 or T3) significantly (p<0.05) improved the feed conversion efficiency and reduced the feed cost of goats compared with solely concentrate pellet group (T1). The results indicated that grass intake and feed cost can be reduced by replacing concentrate pellet with soya waste in the diet of goats where soya waste is available.

    Sains Malaysiana, 2016;45:411-416.
    Bacterial adherence to connective tissue, especially to collagen has been vastly known for their invasive and infectious activities. However, the ability to exploit the unique and specific interactions between bacteria and collagen as a novel approach in detection of placental collagen has never been explored. This study aimed to determine bacteria with binding specificity to placental collagen (Type IV) derived from human and sheep. In order to do this, total bacteria from small intestines of pig and cow were isolated and their ability to bind to Type IV placental collagen (human and sheep) was determined. Interestingly, three bacterial samples; P5, P9 (pig small intestine origin) and B7 (cow small intestine origin) were found to be able to bind strongly to the placental collagen. The bacterial binding to human placental collagen was however, diminished after the bacteria were treated with trypsin, proteinase K (for removal of surface protein) and guanidine hydrochloride (for S-layer removal), suggesting that the interaction of these bacteria to placental collagen was promoted by protein(s) present at the bacterial surface. In addition, significant reduction of placental collagen-binding ability of the bacteria pre-incubated with soluble human placental collagen showed that there is a specific interaction between the bacteria and collagen. P5, P9 and B7 bacteria were found to share 95-97% 16S rRNA sequence similarity to Enterococcus faecalis ZL, Enterococcus hirae ss33b and Enterococcus faecium M3-1, respectively. The results presented here may facilitate future studies in identifying bacterial surface protein(s) responsible for the specific binding of bacteria to collagen and opens new opportunity to utilize the protein(s) for the detection of placental collagen in nutraceutical and food supplements.

    Ahmed Asrity S, Tsan FY, Ding P, Syed Aris S
    Sains Malaysiana, 2014;43:1471-1475.
    Phaleria macrocarpa seeds are rapidly killed with desiccation to moisture content (MC) below 20%. Desiccation tolerance of their embryonic axes was studied for storage and germplasm conservation purposes. Embryonic axes were extracted aseptically from fresh seeds obtained from fully ripe fruits in a horizontal laminar air flow cabinet. They were then desiccated under aseptic condition for periods ranging from 0-8 h. For each desiccation treatment, embryonic axes were drawn randomly for the determination of MC according to ISTA, electrolyte leakage and proliferation on Murashige and Skoog (MS) media supplemented with 1 mg/l 6-benzylaminopurine (BAP) and 1 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D). The results obtained from this study indicated that the embryonic axes could tolerate dehydration down to 13.6% with desiccation for 8 h while retaining relatively high viability of 76.7%. This was supported by only gradual increment of electrolyte leakage with the desiccated embryonic axes. All non-desiccated embryonic axes with MC of 52.5% were capable to grow into normal plantlets in vitro but dehydration to MC of 36.0% and further down to 13.6% generally resulted in callus formation with up to 16.7% of the embryonic axes while at least 60.0% of the other embryonic axes were still capable to proliferate as normal plantlets in vitro.

  14. A review on Selenium-enriched green tea: fortification methods, biological activities and application prospect
    Jin Liang, Pradeep Puligundla, Sanghoon Ko, Xiao-Chun Wan
    Sains Malaysiana, 2014;43:1685-1692.
    Selenium (Se) has been recognized as an essential nutrient for humans. Plant foods are the predominant source of selenium and majority of dietary selenium is absorbed depending on the type of food consumed. Nowadays, green tea is becoming increasingly popular for its prominent health benefits, including the ability to supplement selenium in organically bound, natural food form. The selenium content of Se-enriched green tea is influenced by the selenium level of local soils in which it is grown. However, selenium content of plants can also be improved by artificial fortification methods. In this review, the chemical speciation and biological functions of selenium, fortification methods, biological activities and nutraceutical applications of Se-enriched green tea are discussed. This review provides insights into the current research and the importance of Se-enriched green tea in the enrichment of human nutrition and health.

    Sains Malaysiana, 2018;47:3031-3041.
    A comparative analysis of metabolites from different parts of Curcuma aeruginosa, i.e. leaves, stems, adventitious
    roots and rhizomes was performed by GC-MS/MS coupled with multivariate statistical analysis. The GC-MS/MS analysis
    confirmed the occurrence of 26 metabolites belonged to terpenoids in almost all the samples. The Principal Component
    Analysis (PCA) indicated that there was a clear distinction between rhizomes and other plant parts, i.e. stems, leaves,
    and adventitious roots that could be explained by relatively higher contents of terpenoids including curzerene, alphafarnesen, furanocoumarin, velleral, germacrone cineole, borneol, beta- and gamma- elemene and methenolone. The
    results of Hierarchical Clustering Analyses (HCA) corresponded with the PCA results where many terpenoids found
    abundantly high in rhizome were clustered together. This was supported by the Pearson correlation analysis that
    showed a significantly good relationship between those terpenoids. The adventitious roots demonstrated the strongest
    antioxidant activity as compared to the other plant parts which could be attributed to its highest Total Phenolic
    Contents (TPC). Total phenolic contents of all the plant parts were positively correlated with their antioxidant activities
    which indicate that phenolic compounds may play a role in the overall antioxidant activities of the plants. The results
    of the study highlighted the potential of this underexploited Curcuma species which could serve as a new source of
    important phytochemicals and natural antioxidant that could be incorporated in functional foods and nutraceuticals.
    In addition, chemical and biological evidence shown in the present work has rationalised the different uses of various
    plant parts of C. aeruginosa.

  16. The effects of Malaysian herb, labisia pumila var. Alata on oestrous cyclicity and reproductive parameters of nulliparous rats
    Wan Ezumi Mohd Fuad, Hasnan Jaafar, Siti Amrah Sulaiman
    Sains Malaysiana, 2017;46:1721-1726.
    Numerous nutraceutical products containing the powdered or extracted parts of Labisia pumila (Myrsinaceae) have been widely available for years in Malaysia, aimed at women of reproductive age. However, there is scarce of information concerning the effects of this plant on the reproductive function of nulliparous females prior to the present study. The toxicity potential of Labisia pumila var. alata (LPA) on oestrous cycle and reproductive parameters was evaluated in groups of 40 virgin rats. They were administered with LPA at the doses of 0 (control), 20, 200 or 1000 mg/kg/day for duration of three weeks. The results obtained indicated that the administration of LPA at all dose levels did not cause mortality nor show noticeably any treatment-related signs of toxicity on the physical appearance, behaviour and body weight of all the rats studied. The pattern and length of oestrous cyclicity as well as the changes in reproductive hormones were statistically comparable among groups. No indications of abnormalities in the histology of uterus and vagina were observed. However, the presence of ovarian follicular cysts has raised apprehension that requires further investigation. The current findings suggested that oral treatment of LPA were associated with toxicity concerns

  17. Fulltext Strides towards the realization of cure for cartilage defects and osteoarthritis: the limitation and regulatory challenges
    Ude Chinedu Cletus, Azizi Miskon, Ruszymah Idrus
    Sains Malaysiana, 2018;47(11):2757-2767.
    Despite remarkable mechanical durability and strength, hyaline cartilage has very limited capacity for self-repair when injured and over time, may degenerate to osteoarthritis. We evaluated the most significant mile stones attained, in the pursuit of cure for cartilage defects and osteoarthritis. The basic treatment options include: Natural or physical therapy, medications, nutritional supplements, nutriceuticals and chondroprotective agents. Next are repairs and replacements, which include surgical procedures: Debridement/chondroplasty, microfracturing, mosaicplasty, periosteum transplantation, osteochondral autografting and allografting, high tibial osteotomy and total knee arthroplasty. But, current trend has shifted from repair, replacement, to most recently regeneration. Regenerations include the cell and gene therapies. While cell therapy involves the use of cells isolated from different tissues to cause regeneration of cartilage; gene therapy involves the selection of appropriate gene and optimal vector to incorporate cDNA. There has been much positivity reported with big animal models, which has led to several ongoing clinical trials. Translations of these findings hold high promises, though not without inherent regulatory hurdles. Considering the initial success rates, there are increasing hopes of realizing these treatments from bench to bedsides. Significant improvements in the treatment of cartilage degenerations and osteoarthritis have been made so far, but no gold standard delineated.

  18. Foliar Boron spray for improved yield, oil quality and water use efficiency in water stressed sunflower
    Shehzad MA, Maqsood M, Abbas T, Ahmad N
    Sains Malaysiana, 2016;45:1497-1507.
    Boron (B) is a mineral considered essential for improving sunflower (Helianthus annuus L.) resistance to drought. B supplements (0, 15-, 30- and 45 mg L-1) under well-watered and variable water deficit levels (64 and 53 mm irrigation depths) were evaluated for their effects on growth, oil quality and water use efficiency (WUE) in a field study for two consecutive years (i.e. 2011 and 2012). The duration of 50% inflorescence emergence, 50% flowering and 50% maturity stages were reduced with increasing moisture stress. All B application rates improved sunflower growth compared to no B control treatment. The moisture deficit treatments of 64 and 53 mm irrigation depths significantly (p<0.05) reduced the yield-related components. Achenes/head, achenes weight and achene yield under water stress conditions were considerably improved by foliar application of B at 30 mg L-1. An increase in protein contents and a decrease in oil contents were observed with B foliar application under moisture deficit treatments. Foliar application of B (30 mg L-1) on water stressed plants also resulted in increased WUE. The highest net benefits were achieved with B concentration of 30 mg L-1 under well-watered and mild deficit water level of 64 mm irrigation depth. The highest application rate of B (45 mg L-1) gave the best results at the most severe water deficit level. In conclusion, the B rates of 30 and 41 mg L-1 performed best for improving drought tolerance in terms of higher sunflower productivity under mild and higher water deficit conditions

    Sains Malaysiana, 2018;47:1801-1810.
    The prevalence of osteoporosis is increasing in Asian countries. Optimum calcium intake and vitamin D level are
    important to prevent osteoporosis. The attitude of the society towards calcium food sources and supplements, as well
    as sun exposure, influence their bone health practices. This review aimed to summarize the current literature on the
    attitude of Asians on calcium and vitamin D rich foods and supplements to understand the barriers among the Asians
    in achieving adequate calcium intake and vitamin D level. Studies showed that most Asians have a negative attitude
    towards calcium-rich foods, mainly dairy products due to lactose intolerance, aversion to the taste of dairy products or
    the absence of motivation. Although they took supplements to fill the gap in their diet, they were not aware of the daily
    recommended intake of calcium. Besides, the majority of them have a negative attitude towards sun exposure due to the
    fear of getting skin cancer or tanning. As a conclusion, most of Asians are still not aware of the importance of calcium
    and vitamin D for their health and their negative attitude must be corrected to prevent the rise of osteoporosis.

    Abundant natural products with medicinal properties have been used as food and traditional medicine for diabetes mellitus all over the world. Psidium guajava fruit from the family of Myrtaceae has gained attention for its antioxidant potential. This study was conducted to determine the effects of P. guajava fruit peel aqueous extract on oxidative stress of pancreas in streptozotocin-induced (45 mg/kg) diabetic rats. Diabetic rats were administered with 400 mg/kg of aqueous extract of P. guajava fruit peel daily for 28 days duration. The results showed that diabetic rats supplemented with P. guajava extract did not cause significant difference in blood glucose level (p>0.05) as compared with diabetic rats alone. For oxidative stress evaluation, malondialdehyde (MDA) and protein carbonyl level were significantly lower and the activity of superoxide dismutase (SOD) and glutathione (GSH) level were significantly higher (p<0.05) in P. guajava supplemented rats compared with non-supplemented diabetic rats. However, histological observation showed that supplementation of P. guajava extract did not give protective effects towards alterations in pancreas histology in diabetic rats. The findings suggested that aqueous extract of P. guajava fruit peel supplementation has the ability to reduce oxidative stress in pancreas of diabetic rats and may play a role in reducing the development of diabetic complications.
