First Report of Hibiscus Chlorotic Ringspot Carmovirus in Tuvalu

Jones P, Devonshire J, Dabek A, Howells C

Plant Dis, 1998 May;82(5):591.
PMID: 30857000 DOI: 10.1094/PDIS.1998.82.5.591C

In September 1997, plants of Hibiscus manihot (locally called nambele) were observed on Vaitupu Island, Tuvalu, exhibiting an angular leaf mosaic and chlorosis that was not always clearly discernible. Electron microscopy of negatively stained sap from affected leaves revealed the presence of numerous isometric virus particles 28 nm in diameter. Poly-acrylamide gel electrophoresis of purified virus gave a single protein band of Mr 38,000 similar to that of the carmoviruses. Immunosorbent electron microscopy tests with antisera kindly provided by N. Spence showed the virus to be hibiscus chlorotic ringspot carmovirus (HCRSV) (1). This virus is also reported from El Salvador, the U.S., Australia, Thailand, Malaysia, Fiji, the Solomon Islands, and Vanuatu. It is not known how the virus reached Tuvalu but we suspect it was via infected cuttings, which were imported for the production of food supplements to combat acute deficiencies of vitamins A and C in the population. The virus is most likely to have been disseminated throughout the islands and atolls of Tuvalu through infected cuttings. Local spread within fields could occur through contaminated hands and cutting implements because of the ease with which the virus is mechanically transmitted. Reference: (1) H. E.Waterworth et al.

McGrattan A, van Aller C, Narytnyk A, Reidpath D, Keage H, Mohan D, et al.

Crit Rev Food Sci Nutr, 2020 Dec 18.
PMID: 33337250 DOI: 10.1080/10408398.2020.1848785

Dementia represents a key impending global health challenge. The aim of this systematic review was to evaluate the current evidence on nutritional interventions for the prevention of dementia in developing economies in East-Asia. Four comprehensive databases were searched from inception until January 2020: MEDLINE, Embase, PsycInfo, and Scopus. The search was restricted to randomized controlled trials [RCTs] in adult humans, assessing the effect of nutritional interventions on global and domain specific cognitive performance and dementia risk. Meta-analysis of data was conducted for each domain and sub-categorized according to the type of nutritional intervention. Twenty-four RCTs were included, of which, fifteen studies showed significant beneficial effects on cognition. Eighteen studies were included in the meta-analysis. Significant beneficial effects were found for essential fatty acids (EPA/DHA) and micronutrient supplementation on specific cognitive domains including attention and orientation, perception, verbal functions and language skills. The effect size of the interventions appeared to be greater in older subjects with cognitive impairment. Supplementation with B-vitamins and essential fatty acids may represent promising strategies to minimize age-related cognitive decline in Asian populations. Large, high-quality, long-term trials are needed to confirm these findings.

Introduction: Peripheral nerve injuries (PNI) are a disabling injury as it often results in motor and sensory deficit with cognitive impairment. Flaxseed oil provides a good source of omega-3 fatty acid and it is believed to be able to protect the damaged nerve cell for successful nerve recovery. This study aimed to investigate a potential neuro-re- generation properties of flaxseed oil in treating the PNI. Methods: A total of 65 rats were separated into 4 groups: Group 1: Normal group (n=5), Group 2: Negative group (n=20), Group 3: Experimental group (n=20) and Group 4: Positive control (n=20), all the group were further divided into 4 groups (post-operative 7, 14, 21, 28 days, n=5 for each days). The functional restoration was assessed by walking track analysis (Sciatic Functional Index analysis-SFI) and toe spreading reflex (grading score). Electron microscope studies were performed on sciatic nerve to evaluate the regenerative process through morphologic and morphometric changes. Results: Oral administration of flaxseed oil (experimental group) at 1000 mg/kg body weight/day showed better recovery compared to negative control value. However, there was no significant difference in SFI and toe spreading reflex between positive (mecobalamin) and experimental group (flaxseed oil). Morphological and morphometrical findings indicated increases in the myelin thickness and myelin sheath layer after administration of flaxseed oil. Conclusion: The flaxseed oil supplementation could enhance the neurorestorative capacities of injured sciatic nerve.

Fulltext The Effect of Isoleucine Supplementation on Body Weight Gain and Blood Glucose Response in Lean and Obese Mice

O'Rielly R, Li H, Lim SM, Yazbeck R, Kritas S, Ullrich SS, et al.

Nutrients, 2020 Aug 14;12(8).
PMID: 32823899 DOI: 10.3390/nu12082446

Chronic isoleucine supplementation prevents diet-induced weight gain in rodents. Acute-isoleucine administration improves glucose tolerance in rodents and reduces postprandial glucose levels in humans. However, the effect of chronic-isoleucine supplementation on body weight and glucose tolerance in obesity is unknown. This study aimed to investigate the impact of chronic isoleucine on body weight gain and glucose tolerance in lean and high-fat-diet (HFD) induced-obese mice. Male C57BL/6-mice, fed a standard-laboratory-diet (SLD) or HFD for 12 weeks, were randomly allocated to: (1) Control: Drinking water; (2) Acute: Drinking water with a gavage of isoleucine (300 mg/kg) prior to the oral-glucose-tolerance-test (OGTT) or gastric-emptying-breath-test (GEBT); (3) Chronic: Drinking water with 1.5% isoleucine, for a further six weeks. At 16 weeks, an OGTT and GEBT was performed and at 17 weeks metabolic monitoring. In SLD- and HFD-mice, there was no difference in body weight, fat mass, and plasma lipid profiles between isoleucine treatment groups. Acute-isoleucine did not improve glucose tolerance in SLD- or HFD-mice. Chronic-isoleucine impaired glucose tolerance in SLD-mice. There was no difference in gastric emptying between any groups. Chronic-isoleucine did not alter energy intake, energy expenditure, or respiratory quotient in SLD- or HFD-mice. In conclusion, chronic isoleucine supplementation may not be an effective treatment for obesity or glucose intolerance.

International Journal of Allied Health Sciences, 2018;2(1):179-190.
MyJurnal

Pregnancy is a crucial period for mothers to ensure proper weight gain and adequate nutrients intakes. This is important for healthy fetal growth. There are increasing numbers of maternal milk supplements which claimed to provide the essential nutrients that are needed during pregnancy such as iron, folic acid, and docohexanoic acid. The current study was conducted to assess the practice of maternal milk supplements (MMS) intake among pregnant women in Kuantan, Pahang, whether or not its consumption plays a role in meeting the requirements for total energy and
nutrients intakes. Questionnaires regarding intake of MMS were distributed to 150 subjects to observe the practice of its consumption. A total of 54 subjects (from 2nd and 3rd trimesters) were interviewed to obtain their diet history using multiple pass 24-hours dietary recall method. Their total energy and nutrients intakes were compared to the Recommended Nutrients Intake for Malaysia (RNI, 2005). It was found that almost three quarter (70%) of the subjects consumed MMS. Women who consumed MMS during pregnancy were found to be significantly younger, of lower parity and lower pre-pregnancy body mass index. It was also shown that the women’s dietary intakes without MMS supplementation were insufficient to meet the RNI for total energy and
some selected nutrients. The results of this study indicate that MMS could play a role in increasing the dietary intakes of total energy, protein, and calcium, of pregnant women who are not consuming these nutrients sufficiently as recommended.

Fulltext Comparative Efficacy of Selected Phytobiotics with Halquinol and Tetracycline on Gut Morphology, Ileal Digestibility, Cecal Microbiota Composition and Growth Performance in Broiler Chickens

Basit MA, Kadir AA, Loh TC, Abdul Aziz S, Salleh A, Zakaria ZA, et al.

Animals (Basel), 2020 Nov 19;10(11).
PMID: 33227911 DOI: 10.3390/ani10112150

The current experiment was designed to estimate the comparative efficacy of selected phytobiotics Persicaria odorata leaf meal (POLM) and Piper betle leaf meal (PBLM) with halquinol, and tetracycline in broiler chickens. The 150-day-old broiler chickens were randomly assigned to five dietary groups. The dietary supplementation groups were the basal diet (BD), which served as the negative control (NC), and BD + 0.2 g/kg tetracycline, which served as the positive control (PC); BD + 0.03 g/kg halquinol (HAL), BD + 8 g/kg POLM (Po8), and BD + 4 g/kg PBLM (Pb4) were the treatment groups. Growth performance, gut morphology, ileal digestibility, and cecal microbiota composition were measured. On day 21, the body weight gain (BWG) was enhanced (p < 0.05) in the broiler chickens fed on phytobiotics (Po8 and Pb4) relative to the NC group, however, on day 42 and in terms of overall growth performance, BWG was enhanced (p < 0.05 in diets (Po8, Pb4, HAL and PC) in comparison with the NC group. Conversely, feed conversion ratio (FCR) was recorded reduced (p < 0.05) in Pb4, Po8, HAL, and PC group in comparison with the NC group. Supplementation of phytobiotics (Po8 and Pb4), HAL and PC, positively improved the gut morphology compared to the NC group. Furthermore, the maximum (p < 0.05) villus height (VH) in duodenum and jejunum was observed in broilers fed on diet Pb4. Supplementation of phytobiotics, HAL and PC, improved (p < 0.05) the digestibility of dry matter (DM) (except for HAL), organic matter (OM), crude protein (CP), ether extract (EE), and ash compared to the NC group. Dietary supplementation of phytobiotics (Po8 and Pb4), HAL and PC, significantly reduced the E. coli, Salmonella, and Staphylococcus aureus (except for HAL) counts compared to the NC group. However, supplementation of Pb4 resulted in significantly decreased total anaerobic bacteria and Clostridium spp. counts compared to the NC group. In addition, supplementation of phytobiotics significantly increased the Lactobacillus count compared to HAL, PC, and NC groups. In conclusion, dietary supplementation of phytobiotics improved the gut morphology, positively modulated and maintained the dynamics of cecal microbiota with enhanced nutrient digestibility, thus, increased the growth performance. Based on current results, phytobiotics could be used as an alternative to AGPs for sustainable broiler chicken production.

International Food Research Journal, 2020;27(4):683-693.
MyJurnal

Nowadays, functional food market is dominated by dairy-based probiotic products, mainly
yogurt. The nutritional values of yogurt can be further enhanced by the inclusion of miracle
fruit (Synsepalum dulcificum) and potential probiotic Lactococcus lactis Gh1. The present
work investigated the anti-oxidative capacity and survivability of probiotic strains of six
yogurts fortified with S. dulcificum pulp extract and encapsulated L. lactis Gh1 (in
alginate-starch coating agent via extrusion technique). The flavonoid contents (TFC) were not
significantly different between yogurts, whereas the phenolic contents (TPC) showed an
increasing trend throughout the storage. Among the yogurts, the one supplemented with both
S. dulcificum and encapsulated L. lactis Gh1 showed the highest TFC (1.18 µg QE/mL) and
TPC (15.382 μg GAE/mL). The antioxidant assay (DPPH) showed a gradual increase on the
first 7 d, but decreased afterward. In comparison, yogurts fortified with S. dulcificum demonstrated higher antioxidant activity (± 80% DPPH inhibition) than the plain yogurts (± 50%
DPPH inhibition). The viability of starter cultures (Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus) drastically increased during the first week (log 8 ~ 10
CFU/mL) especially for yogurts containing free cell L. lactis, but subsequently decreased ( log
6 ~ 8 CFU/mL). The viability of L. lactis Gh1 in yogurts maintained at high count (log 9.43
and 9.04 CFU/mL) throughout 21 d when it was being encapsulated. In general, the fortification of S. dulcificum extract with microencapsulated L. lactis Gh1 had greatly enhanced the
quality and potential benefits of the functional yogurts.

Khazdouz M, Djalalinia S, Sarrafi Zadeh S, Hasani M, Shidfar F, Ataie-Jafari A, et al.

Biol Trace Elem Res, 2020 Jun;195(2):373-398.
PMID: 31494808 DOI: 10.1007/s12011-019-01870-9

The prevalence of cardiometabolic risk factors has been increasing worldwide. The results of reported studies on the effects of zinc supplementation on cardiometabolic risk factors are unequivocal. This systematic review and meta-analysis of randomized controlled trials was conducted to evaluate the effects of zinc supplementation on cardiometabolic risk factors. A systematic search was conducted through international databases (PubMed/Medline, Institute of Scientific Information, and Scopus) until December 2018 to include all randomized controlled trials (RCT), quasi-RCT, and controlled clinical trials which assessed the effect of zinc supplementation on cardiometabolic risk factors including lipid profile, glycemic indices, blood pressure, and anthropometric indices. Random- or fixed-effects meta-analysis method was used to estimate the standardized mean difference (SMD) and 95% confidence interval (CI). A total of 20 studies were included in the meta-analysis, which included a total of 1141 participants in the intervention group. Meta-analysis showed that zinc supplementation significantly decreased plasma levels of triglyceride (SMD - 0.66, 95% CI - 1.27, - 0.06), very-low-density lipoprotein (SMD - 1.59, 95% CI - 2.86, - 0.31), and total cholesterol (SMD - 0.65, 95% CI - 1.15, - 0.15). Similarly, zinc supplementation significantly decreased fasting blood glucose (SMD - 0.52, 95% CI - 0.96, - 0.07) and HbA1c (SMD - 0.64, 95% CI - 1.27, - 0.02). The effects of zinc supplementation on blood pressure and anthropometric indices were not statistically significant (P > 0.05). Zinc supplements had beneficial effects on glycemic indices and lipid profile. Thus, it appeared that zinc supplementation might be associated with a decrease in cardiometabolic risk factors contributing to a reduction in risk of atherosclerosis.

Role of Palm Oil Vitamin E in Preventing Pre-eclampsia: A Secondary Analysis of a Randomized Clinical Trial Following ISSHP Reclassification

Aminuddin NA, Sutan R, Mahdy ZA

Front Med (Lausanne), 2020;7:596405.
PMID: 33553199 DOI: 10.3389/fmed.2020.596405

Background: Preeclampsia is a significant cause of maternal and perinatal mortality worldwide. Oxidative stress plays a key role in its pathophysiology, hence antioxidants such as tocotrienol may be preventive against preeclampsia. In 2018, the ISSHP revised the definition of preeclampsia. In accordance with the new definition, we report a secondary data analysis from a clinical trial comparing palm oil vitamin E in the form of tocotrienol-rich fraction (TRF) against placebo, in preventing preeclampsia. Method: A randomized double-blind controlled trial was conducted in 2002-2005 to assess the benefits of TRF in preeclampsia prevention. A total of 299 primigravidae were recruited. The intervention group was supplemented with TRF 100 mg daily in super-olein capsules, whereas the placebo group was prescribed super-olein capsules without TRF, beginning from 12 to 16 gestational weeks until delivery. The primary outcome measure was incidence of preeclampsia. Results: The total incidence of pregnancy induced hypertension (PIH) was 5%, whereas the incidence of preeclampsia was 2.3%. The odds of developing PIH (adjusted OR 0.254; 95% CI: 0.07-0.93; p-value 0.038) and preeclampsia (adjusted OR 0.030; 95% CI: 0.001-0.65; p-value 0.025) were significantly lower in the TRF arm compared to the placebo arm. Conclusion: Antenatal supplementation with palm oil vitamin E in the form of TRF is associated with significant reductions in the incidence of preeclampsia and PIH in a single urban tertiary hospital. Palm oil vitamin E deserves further scrutiny as a potential public health preventive measure against preeclampsia and PIH.

Fulltext Supplementation with red palm oil increases β-carotene and vitamin A blood levels in patients with cystic fibrosis

Sommerburg O, De Spirt S, Mattern A, Joachim C, Langhans CD, Nesaretnam K, et al.

Mediators Inflamm, 2015;2015:817127.
PMID: 25688177 DOI: 10.1155/2015/817127

Patients with cystic fibrosis (CF) show decreased plasma concentrations of antioxidants due to malabsorption of lipid soluble vitamins and consumption by chronic pulmonary inflammation. β-Carotene is a major source of retinol and therefore is of particular significance in CF. The aim of this study was to investigate the effect of daily intake of red palm oil (RPO) containing high amounts of β-carotene on the antioxidant levels in CF patients. Sixteen subjects were recruited and instructed to enrich their food with 2 to 3 tablespoons of RPO (~1.5 mg of β-carotene) daily over 8 weeks. Carotenoids, retinol, and α-tocopherol were measured in plasma at baseline and after intervention. In addition β-carotene, lycopene, α-tocopherol, and vitamin C were measured in buccal mucosa cells (BMC) to determine the influence of RPO on antioxidant tissue levels. Eleven subjects completed the study properly. Plasma β-carotene, retinol, and α-carotene of these patients increased, but plasma concentrations of other carotenoids and α-tocopherol as well as concentrations of β-carotene, lycopene, α-tocopherol, and vitamin C in BMC remained unchanged. Since RPO on a daily basis did not show negative side effects the data suggest that RPO may be used to elevate plasma β-carotene in CF.

Fulltext Optimisation of the production of fish gelatine nanoparticles as a carrier for sunflower-derived biopeptide

Akbar, I., Jaswir, I., Jamal, P.

International Food Research Journal, 2020;27(1):171-181.
MyJurnal

Gelatine obtained from fish skin has become a potential source of preparing nanoparticles and
encapsulation of bioactive compounds. Within these fish skin, gelatine nanoparticles show
potent benefits for application in pharmaceutical and cosmetic industry. The encapsulated
bioactive ingredients within nanoparticles have improved bioavailability, delivery properties,
and solubility of the nutraceuticals within the human body and blood stream. Many of such
bioactive peptides (biopeptides) are potent antioxidants; and as oxidative stress is the main
cause of the onset of various chronic diseases, encapsulation of antioxidant biopeptides within
fish gelatine nanoparticles could be a potential remedy to prevent or delay the onset of such
diseases and for better health prospects. The purpose of the present work was to prepare a
simple, safe, and reproducible novel food delivery nanoparticle system encapsulating a desirable antioxidant biopeptide. An optimisation study was conducted to produce a desirable size
of gelatine nanoparticles which showed a higher encapsulation efficiency of an antioxidant
biopeptide. Sunflower biopeptide was chosen as the antioxidant biopeptide, as the activity of
this protein hydrolysate is quite high at DPPH of 89% and FRAP assay of 968 µm/L. Tilapia
fish was used as gelatine source at an average yield of the process at 10% wt/wt. Effects of
parameters such as pH, biopeptide concentration, and cross-linking agent ‘glutaraldehyde’ on
the size, stability, and encapsulation efficiency on the nanoparticles were studied. The average
diameter of the biopeptide loaded gelatine nanoparticle was between 228.3 and 1,305 nm.
Encapsulation efficiency was 76% at an optimal pH of 2, glutaraldehyde concentration of 2
mL, and biopeptide concentration of 0.1 mg/mL exhibited DPPH at 92% and FRAP assay of
978 µm/L. To understand the absorption of sunflower biopeptide in stomach, blood stream,
and biopeptide release of the gelatine nanoparticles, biopeptide loaded gelatine nanoparticles
were subjected to simulated gastrointestinal conditions mimicking human stomach and
intestine; and showed peptide release of 0.1464 and 0.277 mg/mL upon pepsin and pancreatin
digestion, respectively.

Fulltext Edible Bird's Nest Supplementation Improves Male Reproductive Parameters of Sprague Dawley Rat

Jaffar FHF, Osman K, Hui CK, Zulkefli AF, Ibrahim SF

Front Pharmacol, 2021;12:631402.
PMID: 33986667 DOI: 10.3389/fphar.2021.631402

Edible bird's nest (EBN) is reported to have a positive in vitro proliferative effect and contain male reproductive hormones. Spermatogonia cells proliferate during spermatogenesis under male reproductive hormones stimulation that include testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH). Characterization of EBN through liquid chromatography-mass spectrometry (LCMS) has found testosterone as a base peak. Six types of amino acids, estradiol and sialic acid were among the major peaks that have been characterized. Based on the presence of these reproductive components, this study evaluated different doses of EBN on sperm parameters and male reproductive hormones of Sprague Dawley rats. Sixteen Sprague Dawley rats at the age of eight weeks were randomly and equally divided into four groups, which are Control, 10 mg/kg BW/d 50 mg/kg BW/d, and 250 mg/kg BW/d EBN group. The rats were fed with EBN enriched pellet daily and water ad-libitum. Rats were sacrificed and the organ was weighed for organ coefficients after eight weeks of treatment. Sperm concentration, percentage of sperm motility, and sperm viability were evaluated. Meanwhile, ELISA method was used to measure testosterone, FSH, and LH. Findings showed that there were no significant differences in organ coefficient between groups. Supplementation of 250 mg/kg BW/d EBN demonstrated a significant increase in sperm concentration, percentage of sperm motility as well as FSH and LH level compared to 10 mg/kg BW/d group. There was a dose-dependent increase in testosterone level but was not significant between groups. Based on these findings, EBN is concluded to have crucial effects on male reproductive parameters.

PMID: 33228578 DOI: 10.1186/s12884-020-03397-7

BACKGROUND: Vitamin D deficiency (VDD) has been related to vitamin D binding protein (GC) gene polymorphism, demographics and lifestyle factors in different populations. However, previous studies only focused on demographic and lifestyle factors or genetic factors alone. Therefore, this cross-sectional study aimed to assess the association between GC gene polymorphism, demographics and lifestyle factors with VDD among Malaysian pregnant women.
METHOD: Information on demographic characteristics, dietary vitamin D intake from supplement and food, time spent outdoors, skin type and clothing were collected using a questionnaire. Plasma total 25-hydroxyvitamin D (25OHD) levels were measured using an Ultra-High-Performance Liquid Chromatography (UHPLC). Maternal GC single nucleotide polymorphisms (SNPs) (rs4588 and rs7041) were determined using restriction fragment length polymorphism (RFLP) technique.
RESULTS: Results showed that 50.2% of pregnant women were vitamin D deficient (25OHD

Introduction: Iron deficiency anaemia (IDA) is endemic especially in the under-developed and developing countries and is a major public health concern. Improving nutrition is one of the ways to alleviate this condition. Consumption of locally available and affordable food such as date palm and goat milk which are rich in iron is one of the ways to overcome IDA. This study is aimed at evaluating the effect of date palm and goat milk supplementation on hae- matological parameters and iron bioavailability in IDA rats. Methods: 24 male Wistar rats were randomly divided into normal control and IDA group. The normal control was fed with normal diet and water ad libitum while the IDA group were fed on iron-deficient diet for two weeks to induce iron deficiency. The IDA rats were further divided into subgroups; each being supplemented with date palm, goat milk, a combination of date palm and goat milk, and ferrous fumarate as positive control. Blood were collected after 28 days for haematological parameters and iron profile determination. Iron bioavailability was assessed using the haemoglobin regeneration efficiency (HRE) index. Data was analysed by Student T Test and ANOVA using SPSS 23.0 software with p value < 0.05 considered as sta- tistically significant. Results: Supplementation of date palm and goat milk for 28 days significantly improved Hb, RBC, PCV, MCV, MCH, serum iron and transferrin saturation (p

Fulltext Effect of Sodium Selenite, Selenium Yeast, and Bacterial Enriched Protein on Chicken Egg Yolk Color, Antioxidant Profiles, and Oxidative Stability

Muhammad AI, Mohamed DAA, Chwen LT, Akit H, Samsudin AA

Foods, 2021 Apr 16;10(4).
PMID: 33923439 DOI: 10.3390/foods10040871

The chicken egg is one of nature's flawlessly preserved biological products, recognized as an excellent source of nutrients for humans. Selenium (Se) is an essential micro-element that plays a key role in biological processes. Organic selenium can be produced biologically by the microbial reduction of inorganic Se (sodium selenite). Therefore, the possibility of integrating Se enriched bacteria as a supplement in poultry feed can provide an interesting source of organic Se, thereby offering health-related advantages to humans. In this study, bacterial selenoproteins from Stenotrophomonas maltophilia was used as a dietary supplement with other Se sources in Lohman brown Classic laying hens to study the egg yolk color, egg yolk and breast antioxidant profile, oxidative stability, and storage effect for fresh and stored egg yolk at 4 ± 2 °C for 14-days. The results showed that dietary Se supplementation significantly (p < 0.05) improved egg yolk color, the antioxidant profile of egg yolk, and breast meat (total carotenoid and phenol content). When the Se treated groups were compared to control groups, there was a significant (p < 0.05) decrease in total cholesterol in fresh and stored egg yolk and breast muscle. In hens that were fed ADS18-Se, the primary oxidation products (MDA) concentrations in the eggs, breast, and thigh muscle, and plasma were significantly (p < 0.05) lower. However, the MDA content increased (p < 0.05) with an extended storage time in egg yolk. In comparison to inorganic Se and basal diets, egg yolk from hens fed organic Se remained fresh for two weeks. The egg yolk color, antioxidant profile, and oxidative status of egg yolk and tissue improve with dietary Se organic supplementation (ADS18 > Se-Yeast). The source of supplemented organic Se is critical for egg enrichment and antioxidant properties. As a result, ''functional eggs'' enriched with organic Se becomes possible to produce.

Introduction: An economical and alternative diabetic wound care product is needed to address the escalating cost of diabetic wound ulcer treatment in Indonesia. Morindac itrifolia or commonly called noni, is a medicinal plant, dietary supplement, and traditional wound care product. This leaves extract contains antioxidant, anti-inflammatory, immune-stimulant, and antimicrobial properties. Trigona honey which is currently used to treat the diabetic wound at Kitamura Wound Specialist Clinic, Pontianak, Indonesia is known for its anti-inflammatory, anti-microbial and anti-proliferative properties. This study aims to compare the effectiveness of Morinda citrifolia leaves extract and Trigona honey in diabetic wound healing. Methods: A quasi-experimental study (a randomized control trial design) was conductedin the clinicon two subjects with diabetic foot ulcers (DFU). Trigona honey and Morinda citrifolia leaves extract packing was done to the ulcer of controlled subject and treatment subject respectively as a primary dressing. DFU assessment was done every 2 days using the MUNGS assessment tool and a wound closure rate for- mula. Wound C&S was analysed using a bacterial count machine. Results: Morinda citrifolia leaves extract was able to promote wound contraction, improved MUNGS score (from 9 to 8), reduced bacteria count significantly (from
8.51 x 105 to 1.00 x 105), reduced the percentage of slough by 70% and increased granulating tissue by 60% after the first application. Whereas, Trigona honey extract showed no wound contraction but improved MUNGS score (from 11 to 7). However, bacteria count was maintained at the lowest level (1.00 x 105), reduce the percentage of slough by 10%, and only increased granulating tissues by 10% after the first application. Conclusion: Both products were able to promote diabetic wound healing but the Morinda citrifolia leaves extract was found to be more effective, thus concludes the potential use of Morinda citrifolia leaves extract in treating DFU.

OBJECTIVES: Globally, nutraceuticals have been increasingly used. Nevertheless, the consumer preferences for nutraceuticals have not been quantitatively investigated. This study used discrete choice experiment (DCE) to examine consumer preferences and willingness to pay for nutraceuticals.
METHODS: Four attributes (ie, the scientific proof of effectiveness, the scientific proof of safety, the source of recommendation, and cost) were identified from a systematic review and focus group interviews. They were used to develop a DCE questionnaire. Consumers at community pharmacies in Malaysia were asked to respond to 8 DCE choice sets. A conditional logit model was employed to obtain the relative importance of each attribute and to estimate respondents' WTP for nutraceuticals.
RESULTS: A total of 111 valid responses were analyzed. A negative constant term in the developed model indicated that generally the respondents preferred not to use nutraceuticals before they considered the study attributes. The respondents preferred nutraceuticals with no side effect, clear evidence of effectiveness, and recommendation of a healthcare professional. The respondents were willing to pay $252/month more for nutraceuticals proven with no side effect than for those without proof of safety, and $102/month more for nutraceuticals proven with clear effectiveness than for those without proof of effectiveness.
CONCLUSIONS: Consumers weighed relatively high on the availability of safety and effectiveness proofs when they chose nutraceuticals. The study highlights on the crucial need to inform consumers using clinical evidences of nutraceuticals as the information is highly preferred by consumers.

Diabetes mellitus (DM) is known to cause reproductive impairment. In men, it has been linked to altered sperm quality and testicular damage. Oxidative stress (OS) plays a pivotal role in the development of DM complications. Glutathione (GSH) is a part of a nonenzymatic antioxidant defense system that protects lipid, protein, and nucleic acids from oxidative damage. However, the protective effects of exogenous GSH on the male reproductive system have not been comprehensively examined. This study determined the impact of GSH supplementation in ameliorating the adverse effect of type 1 DM on sperm quality and the seminiferous tubules of diabetic C57BL/6NTac mice. GSH at the doses of 15 mg kg-1 and 30 mg kg-1 was given intraperitoneally to mice weekly for 6 consecutive weeks. The mice were then weighed, euthanized, and had their reproductive organs excised. The diabetic (D Group) showed significant impairment of sperm quality and testicular histology compared with the nondiabetic (ND Group). Diameters of the seminiferous lumen in diabetic mice treated with 15 mg kg-1 GSH (DGSH15) were decreased compared with the D Group. Sperm motility was also significantly increased in the DGSH15 Group. Improvement in testicular morphology might be an early indication of the protective roles played by the exogenous GSH in protecting sperm quality from effects of untreated type 1 DM or diabetic complications. Further investigation using different doses and different routes of GSH is necessary to confirm this suggestion.
