Effect of domestic cooking methods on physicochemical, nutritional and sensory properties of different varieties of brown rice from Southern Thailand and Malaysia

Consumption of brown rice is increasing on account of higher nutritional components such as vitamins, minerals, fibres and antioxidants than white rice. However, the effect of domestic cooking methods on nutritional attributes of brown rice is not well-characterized. Hence, this study aimed to investigate the effect of cooking methods; pressure cooker (PC) and rice cooker (RC) on physicochemical, nutritional and sensory properties of brown rice from five different varieties: Sungyod (SY), Chiang (CH), and Lepnok (LP) of Thai and long grain LS1 and LS2 of Malaysian origin. Peak viscosity (PV) and final viscosity (FV) among uncooked samples were significantly different except for LS1 and LS2. Between cooking methods, protein content (8.17 – 10.14%) was significantly different (p < 0.05) except in SY, LS1 and LS2 varieties whereas fat (1.74 – 2.71%) and ash content (1.15 – 1.46%) showed significant difference (p < 0.05) only in LP and SY varieties. Loss of iron was significantly higher in RC method than PC method but zinc and thiamine was insignificant. The LS1 and LS2 cooked in PC was significantly softer (p < 0.05) than cooked in RC. Hardness of PC cooked rice was correlated with PV (r = –0.965), breakdown viscosity (r = –0.973), setback viscosity (r = –0.944) at p < 0.01 and pasting temperature (r = 0.89, p < 0.05) of uncooked brown rice flours. Overall, PC was found better over RC in terms of cooking time, textural properties, nutrients and sensory attributes

Nutritional outcomes related to household food insecurity among mothers in rural Malaysia

During the past two decades, the rates of food insecurity and obesity have risen. Although a relationship between these two seemingly-paradoxical states has not been repeatedly seen in men, research suggests that a correlation between them exists in women. This study examines nutritional outcomes of household food insecurity among mothers in rural Malaysia. A cross-sectional survey of low-income households was conducted, and 223 households with mothers aged 18-55 years, who were non-lactating, non-pregnant, and had at least one child aged 2-12 years, were purposively selected. A questionnaire was administered that included the Radimer/Cornell Scale, items about sociodemographic characteristics, and anthropometric measurements. Of the households, 16.1% were food-secure whereas 83.9% experienced some kind of food insecurity: 29.6% of households were food-insecure, 19.3% contained individuals who were foodinsecure, and 35.0% fell into the 'child hunger' category. The result reported that household-size, total monthly income, income per capita, and food expenditure were significant risk factors of household food insecurity. Although there was a high prevalence of overweight and obese mothers (52%) and 47.1% had at-risk waist-circumference (=80 cm), no significant association was found between food insecurity, body mass index, and waist-circumference. In conclusion, the rates of household food insecurity and overweight and obesity were high in the study population, although they are looking paradoxical. Longitudinal studies with larger sample-sizes are recommended to further examine the relationship between food insecurity and obesity

Step by step procedures : degradation of polycyclic aromatic hydrocarbons in potable water using photo-Fenton oxidation process

Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic compounds, composed of two or more fused benzene rings and abundantly found in mixed-use areas. Mixed-use areas consist of dense population, urbanization, industrial and agricultural activities. River pollution are common in mixed-use areas and 98% of Malaysia's fresh water supply originates from surface water. The biological degradation, adsorption and advanced oxidation process were documented as the available PAHs treatment for water. To date, the application of the photo-Fenton oxidation process has been reported for the treatment of PAHs from contaminated soil (review paper), landfill leachate, municipal solid waste leachate, sanitary landfill leachate, aniline wastewater, ammunition wastewater and saline aqueous solutions. As for potable water, the application of Fenton reagent was aided with photo treatment or electrolysis not focusing on PAHs removal. • The presented MethodsX was conducted for PAHs degradation analysis in potable water samples using photo-Fenton oxidation process. • The designed reactor for batch experiment is presented. • The batch experiment consists of parameters like concentration of 17 USEPA-PAHs in the prepared aqueous solution (fixed variable), reaction time, pH and molarity ratio of hydrogen peroxide (H2O2): ferrous sulfate (FeSO4)

Cytoskeletal control of B cell responses to antigens.

The actin cytoskeleton is essential for cell mechanics and has increasingly been implicated in the regulation of cell signalling. In B cells, the actin cytoskeleton is extensively coupled to B cell receptor (BCR) signalling pathways, and defects of the actin cytoskeleton can either promote or suppress B cell activation. Recent insights from studies using single-cell imaging and biophysical techniques suggest that actin orchestrates BCR signalling at the plasma membrane through effects on protein diffusion and that it regulates antigen discrimination through the biomechanics of immune synapses. These mechanical functions also have a role in the adaptation of B cell subsets to specialized tasks during antibody responses

BACKGROUND: In 2015, the second cycle of the CONCORD programme established global surveillance of cancer survival as a metric of the effectiveness of health systems and to inform global policy on cancer control. CONCORD-3 updates the worldwide surveillance of cancer survival to 2014. METHODS: CONCORD-3 includes individual records for 37.5 million patients diagnosed with cancer during the 15-year period 2000-14. Data were provided by 322 population-based cancer registries in 71 countries and territories, 47 of which provided data with 100% population coverage. The study includes 18 cancers or groups of cancers: oesophagus, stomach, colon, rectum, liver, pancreas, lung, breast (women), cervix, ovary, prostate, and melanoma of the skin in adults, and brain tumours, leukaemias, and lymphomas in both adults and children. Standardised quality control procedures were applied; errors were rectified by the registry concerned. We estimated 5-year net survival. Estimates were age-standardised with the International Cancer Survival Standard weights. FINDINGS: For most cancers, 5-year net survival remains among the highest in the world in the USA and Canada, in Australia and New Zealand, and in Finland, Iceland, Norway, and Sweden. For many cancers, Denmark is closing the survival gap with the other Nordic countries. Survival trends are generally increasing, even for some of the more lethal cancers: in some countries, survival has increased by up to 5% for cancers of the liver, pancreas, and lung. For women diagnosed during 2010-14, 5-year survival for breast cancer is now 89.5% in Australia and 90.2% in the USA, but international differences remain very wide, with levels as low as 66.1% in India. For gastrointestinal cancers, the highest levels of 5-year survival are seen in southeast Asia: in South Korea for cancers of the stomach (68.9%), colon (71.8%), and rectum (71.1%); in Japan for oesophageal cancer (36.0%); and in Taiwan for liver cancer (27.9%). By contrast, in the same world region, survival is generally lower than elsewhere for melanoma of the skin (59.9% in South Korea, 52.1% in Taiwan, and 49.6% in China), and for both lymphoid malignancies (52.5%, 50.5%, and 38.3%) and myeloid malignancies (45.9%, 33.4%, and 24.8%). For children diagnosed during 2010-14, 5-year survival for acute lymphoblastic leukaemia ranged from 49.8% in Ecuador to 95.2% in Finland. 5-year survival from brain tumours in children is higher than for adults but the global range is very wide (from 28.9% in Brazil to nearly 80% in Sweden and Denmark). INTERPRETATION: The CONCORD programme enables timely comparisons of the overall effectiveness of health systems in providing care for 18 cancers that collectively represent 75% of all cancers diagnosed worldwide every year. It contributes to the evidence base for global policy on cancer control. Since 2017, the Organisation for Economic Co-operation and Development has used findings from the CONCORD programme as the official benchmark of cancer survival, among their indicators of the quality of health care in 48 countries worldwide. Governments must recognise population-based cancer registries as key policy tools that can be used to evaluate both the impact of cancer prevention strategies and the effectiveness of health systems for all patients diagnosed with cancer.

The Association between Visceral Fat and Blood Pressure in Adults

ABSTRACT: This cross-sectional study investigates the association between body composition measurements and blood pressure in Malay adults. A total of 296 adults, aged between 18 to 59 years, consisting of 122 males and 174 females underwent measurements of weight and height, waist and hip circumference, body fat and visceral fat, and blood pressure. Body fat and visceral measurements were carried out through bioelectric impedance, using a portable Tanita body fat analyser. Bivariate correlation analysis was used to study the association of each body composition measurement with blood pressure. There was significant association between Body Mass Index (BMI) (r= 0.25, P&lt;0.01), waist circumference (r= 0.27, P&lt;0.01), hip circumference (r= 0.20, P&lt;0.01) and visceral fat (r= 0.29, P&lt;0.01) with blood pressure, respectively. No significant relationship was found between waist hip ratio (WHR) and total body fat with blood pressure. The association between visceral fat and blood pressure is an interesting finding with regards to this community research setting. It is important to further study the affordability, accuracy and application of bioelectrical impedance technology in community research

A new framework for cost-effective design of Hybrid Power Systems

Development of Power Pinch Analysis (PoPA) for the design and optimisation of Hybrid Power Systems (HPS) is steadily progressing. Even though PoPA has been developed for a wide range of applications in HPS design and analysis, the economic aspect still needs more attention. Screening of various renewable energy (RE) technologies in HPS is crucial as different technologies may have different cost and efficiencies, and affect the overall system economics. This work presents a novel framework for the design of a cost-effective HPS by incorporating PoPA with a cost-screening tool known as the Systematic Hierarchical Approach for Resilient Process Screening (SHARPS). SHARPS, which was originally developed to screen various process changes options in water networks is adapted to perform economic analysis and RE technology screening in power networks. Two strategies namely substitution and intensification have been proposed, in order to customise a cost-effective HPS. The presented framework provides a handy and effective measure to visualise the trade-off between the performance and cost of various potential RE technologies for HPS. Application of the framework on a case study demonstrates that the HPS design has been successfully customised with the RE technology scheme and capacity acceptable to the owner, while meeting its targeted payback period of 10 y
