Seaweeds are an important ingredient of functional foods recommended for daily food, due to their unique compositions and nutritional value. Padina tetrastromatica is a brown edible seaweed that is commonly found along the coastal regions of Peninsular Malaysia and consumed as food by some coastal communities. This study investigates the nutritional and antihyperglycaemic potential of P. tetrastromatica extracts, which is generally accepted as an important functional food. In our methodology, we induced diabetes intraperitoneally in experimental animals with a dose of 65 mg kg−1 body weight of streptozotocin. Oral treatment with 200 and 400 mg kg−1 of P. tetrastromatica ethanolic and ethyl acetate extracts were initiated, respectively, to experimental rats once daily for 18 days. Metformin was used as the positive control. Biochemical estimations and histopathological analysis were included in this study. Treatment with P. tetrastromatica extracts significantly lowered the plasma glucose levels in Streptozotocin-induced diabetic rats. In addition, P. tetrastromatica extract treatment also showed a significant reduction in serum alanine transaminase levels. However, no significant changes were observed in serum aspartate transaminase levels. The ethyl acetate extract of P. tetrastromatica at 400 mg kg−1 dose shows some nephroprotective effect, which is observed from the significant increase in the plasma albumin levels. Histopathological evaluation revealed no marked morphological changes in tissues of the isolated organs of the ethyl acetate extract-treated group, revealing the safe nature of P. tetrastromatica.

Caulerpa racemosa (Forsskal) J. Agardh is a green seaweed used as food and folk medicine since ancient times in the Indo-Pacific region, particularly in southeast Asia. In this study, the proximate nutrient composition, phytochemical, anti-oxidant and anti-diabetic properties of sea grape C. racemosa collected from culture fishponds in Johor, Malaysia were analysed. The contents (dry weight basis) of carbohydrate, crude protein, crude lipids, ash and caloric value obtained were 33.42 ± 1.34%, 20.27 ± 0.14%, 4.20 ± 0.32%, 28.25 ± 0.27% and 2544.67 ± 7.04 cal g−1, respectively. The amino acid score (AAs) and biological protein value (213.43 mg g−1) indicated that C. racemosa presented a better protein quality. The most abundant fatty acids were C16:0 (palmitic acid: 63.27%), followed by C18:1 (oleic acid: 5.80%), and C18:2 ῳ6 (linoleic acid: 5.33%). The analysis of the ash content indicated that essential minerals and trace elements, such as Ca, Fe, and Mn, were present in the seaweed. The total phenolic content (TPC) and total flavonoid content (TFC) observed in the ethyl acetate extract were 17.88 ± 0.78 mg GAE g−1 and 59.43 ± 2.45 mg QE g−1, respectively. The ethyl acetate extract of C. racemosa demonstrated notable anti-diabetic activity in diabetic induced rats. The low (100 mg kg−1) and high (200 mg kg−1) doses of cultivated C. racemosa extract exhibited a significant decrease (p < 0.05) in blood glucose levels while preventing weight loss, reducing plasma AST, ALT levels as a sign of hepatoprotective effect and recording albumin levels similar to positive control in diabetic induced rats. The results support the usefulness of cultivated C. racemosa as a potential functional food.

Over the last decade, food waste has been one of the major issues globally as it brings a negative impact on the environment and health. Rotting discharges methane, causing greenhouse effect and adverse health effects due to pathogenic microorganisms or toxic leachates that reach agricultural land and water system. As a solution, composting is implemented to manage and reduce food waste in line with global sustainable development goals (SDGs). This review compiles input on the types of organic composting, its characteristics, physico-chemical properties involved, role of microbes and tools available in determining the microbial community structure. Composting types: vermi-composting, windrow composting, aerated static pile composting and in-vessel composting are discussed. The diversity of microorganisms in each of the three stages in composting is highlighted and the techniques used to determine the microbial community structure during composting such as biochemical identification, polymerase chain reaction denaturing gradient gel electrophoresis (PCR-DGGE), terminal restriction fragment length polymorphism (T-RFLP) and single strand-conformation polymorphism (SSCP), microarray analysis and next-generation sequencing (NGS) are discussed. Overall, a good compost, not only reduces waste issues, but also contributes substantially to the economic and social sectors of a nation.

Invertebrates are an important source of structurally-diverse and biologically-active halogenated metabolites. The sea hare Aplysia dactylomela Rang has long been known to possess halogenated metabolites of dietary origin that are used as a self-defense mechanism. The compounds from Aplysia dactylomela Rang are comprised mainly of terpenoids and small percentages of C-15 acetogenins, indoles, macrolides, sterols and alkaloids with potent cytotoxic, anti-microbial and anti-inflammatory properties. For decades the metabolites discovered have been investigated for their medical and pharmaceutical applications, so much so that the ecological role of the metabolites has been overlooked. The interaction between Aplysia dactylomela Rang and its diet that is comprised of seaweed can provide information into the distribution and diversity of the seaweed, the application of bioaccumulated secondary metabolites as part of its defense mechanism and the potential roles of these metabolites for adaptation in the marine environment. This paper compiles the diversity of halogenated secondary metabolites documented from Aplysia dactylomela Rang.

This study evaluated the effect of seasonal variation on the physicochemical, biochemical, and nutritional composition of Gracilaria manilaensis. Sampling was designed during the main monsoon seasons in Malaysia—the Southwest monsoon (SWM) and Northeast monsoon (NEM)—to understand the intraspecific variation (p < 0.05). Carbohydrates, protein, and dietary fiber were found to be higher in NEM–G. manilaensis, whereas a higher ash content was quantified in SWM–G. manilaensis. No significant differences were found in crude lipid and moisture content (p > 0.05). Vitamin B2 was calculated as (0.29 ± 0.06 mg 100 g−1) and (0.38 ± 0.06 mg 100 g−1) for the NEM and SWM samples, respectively (p < 0.05). The fatty acid profile showed the dominance of saturated fatty acids (SFAs)—palmitic acids, stearic acid, and myristic acid—while the mineral contents were found to be good sources of calcium (1750.97–4047.74 mg 100 g−1) and iron (1512.55–1346.05 mg 100 g−1). Tryptophan and lysine were recorded as the limiting essential amino acids (EAAs) in NEM G. manilaensis, while leucine and phenylalanine were found to be the limiting EAAs in the SWM samples. None of the extracts exhibited antibacterial properties against the screened strains. The study concluded that seasonal changes have a great effect on the biochemical composition of G. manilaensis.

Background: Diet Management Tool (DMT) is a nutrition assessment system developed by the researchers from Dietetic Programme, School of Health Sciences, Universiti Sains Malaysia (USM).The system has been applied in dietary counselling for the treatment of patients with type 2 diabetes at Hospital Universiti Sains Malaysia(HUSM), replacing the untailored traditional counselling approach.Aim: This study examined the effectiveness of dietary counselling using DMT among type 2 diabetes patients.Method and Material: A parallel-design, controlled trial was performed on 50 participants aged between 30-55 years old with type 2 diabetes. Participants were randomly assigned to two groups: the traditional dietary counselling (control group, n=22) and the DMT (intervention group, n=28). The intervention group received dietary counselling based on DMT while the control group received routine or traditional dietary counselling. The DMT consists of nutrition care modules that tailored to the patients’ needs. Anthropometric (body mass index, BMI), biochemical (fasting blood sugar, estimated average glucose and HbA1c) and food pattern outcomes were measured at baseline, three month, six month and nine month. Data was collected between June 2009 and March 2010.Results: During the baseline study, 46.4% of participants from the intervention group and 45.5% of participants from the control group were classifid as overweight based on World Health Organization (WHO) classifiation. Meanwhile, fasting blood sugar (FBS), estimated average glucose (eAG) and HbA1c level of both groups were higher than the normal range. Intake of energy was higher as compared to individual’s energy requirements. Repeated measure of ANCOVA showed that dietary counselling by the dietitian using DMT signifcantly improved glycaemic control in terms of improving HbA1c and eAG compared to control group (p<0.05). However, there were no signifiant changes in other parameters.Conclusions: In conclusion, tailored intervention approach using DMT gave positive results in improvement of glycaemic control among diabetic patients.

A simple, reliable a 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxy-phenyl)-2-(4-sulfophenyl)-2H-tetrazolium, (MTS) assay was conducted to evaluate the potential cytotoxic effects of levodopa, a “gold standard therapy” for Parkinsonism, and its complex with Hydroxypropyl-β-Cyclodextrin (HP-β-CD) on an astrocyte cell line. The cells were incubated in a range of concentrations from 4.69 to 300 μg/mL levodopa, HP-β-CD or the complex for up to 72 hours. At every 24-hour interval, the optical density (OD), which reflects the number of viable cells, was recorded. In general, linear dose-dependent cytotoxicity profiles were observed for the cells subjected to levodopa or the complex, whereas a slightly triphasic response was observed for the cells exposed to HP-β-CD. A significant difference (P < 0.05) in cytotoxicity was detected between the HP-β-CD-treated group and the levodopa-treated group. In particular, we observed that the cells treated with the complex, even at the highest concentrations (> 200 μg/mL), exhibited improved tolerability in a time-dependent manner, which may indicate the potential ability of HP-β-CD to mask the toxic effects of levodopa via complexation.

Cancer therapy in Malaysia primarily focuses on the clinical management of patients with cancer and malnutrition continues to be one of the major causes of death in these patients. There is a dearth of information on the nutrient intake and status of newly diagnosed patients with cancer prior to the initiation of treatment. The present study aims to assess the nutrient intake and status of newly diagnosed patients with cancer from the East Coast of Peninsular Malaysia. A cross-sectional study was conducted using a convenient sample of newly diagnosed adult patients with cancer (n = 70) attending the Oncology clinic, Hospital Universiti Sains Malaysia in the East Coast of Peninsular Malaysia. Information on socio-demographic characteristics, clinical status, anthropometry, dietary intake and biochemical data including blood samples was obtained. The mean (SD) age, triceps skin fold (TSF), mid upper arm circumference (MUAC) and body mass index (BMI) of participants was 21.1(3.9) years, 17.6(7.9) mm, 24.1(5.5) cm, and 21.1(3.9) Kg/m(2), respectively; 39% participants had BMI <18.5 Kg/m(2). One-third of newly diagnosed patients with cancer were undernourished (i.e. women: MUAC <220 mm; men: <230 mm). The proportion (%) of participants with low haemoglobin (<120 g/L) and serum albumin (<38 g/dL) were 62% and 26%, respectively. The older women had significantly lower macro and micro nutrient intakes compared to men in the same age group (P <0.05). At the time of diagnosis, greater than one-third of patients with cancer from the East Coast of Peninsular Malaysia were underweight and undernourished. The majority of patients with cancer had poor micronutrient intakes; the older women had a poor macro and micronutrient intakes. Before the initiation of rigorous clinical management of patients with cancer, screening for nutritional status, subsequent nutrition counseling, and interventions are essential to improve their nutritional status; consequently, response to cancer therapy, survival and quality of life.
