Ethylene regulates many processes in plant growth, development, and senescence. Two enzymes, ACC synthase and ACC oxidase, are responsible for ethylene biosynthesis from its precursor S-adenosyl Met (Yang and Hoffman, 1984), and blocking the synthesis of these enzymes in antisense RNA experiments results in reduced ethylene synthesis (Hamilton et al., 1990; Oeller et al., 1991). Functional iden...
Geraniums are sensitive to ethylene during shipping and respond by abscising their petals. Treatment of stock plants with ethylene (ethephon) in order to increase cutting yield resulted in earlier flowering in Pelargonium × hortorum ‘Kim’ and ‘Veronica’, but did not result in increased susceptibility to petal abscission following exposure to 1.0 μL·L–1 ethylene. Treatment of ‘Kim’, ‘Veronica’, ...
BACKGROUND In sub-Saharan Africa, ~ 40% of children <5 y old are stunted, with levels that have remained largely unchanged over the past 2 decades. Although the complex determinants of undernutrition are well recognized, few studies have evaluated strategies that combine nutrition-specific, health-based approaches with food system- and livelihood-based interventions. OBJECTIVE We examined cha...
OBJECTIVE To examine the association between household food insecurity (HFI) and risk of childhood stunting and to determine whether this association is modified by maternal-child overweight/obesity. DESIGN Observational cross-sectional study. SETTING Data come from the Mexican National Health and Nutrition Survey (ENSANUT 2012 by its initials in Spanish), representative of rural and urban ...
Objective: To assess the overall nutritional status of Santal tribal preschool children of Paschim Medinipur district, West Bengal, India. Methods: A cross sectional study was conducted from February 2012 to September, 2012 in the Santal tribal community of rural area of Paschim Medinipur District, West Bengal. The study children were selected multi stage cluster sampling method. The leve...
Objective. The main aim of the study was to assess the magnitude of concurrent wasting and stunting among Ghanaian preschool children. Secondly, we investigated the relationship between wasting and stunting as well as factors associated with these conditions. Methods. This paper is based on reanalysis of anthropometric and other relevant data which was collected in the 2014 Ghana Demographic an...
Nutritional status is the best global indicator of well-being in children. Although many surveys of children have been conducted since the 1970s, lack of comparability between them has made it difficult to monitor trends in child malnutrition. Cross-sectional data from 241 nationally representative surveys were analysed in a standard way to produce comparable results of low height-for-age (stun...
Child chronic undernutrition, as measured by stunting, is prevalent in low- and middle-income countries and is among the major threats to child development. While stunting and its implications for cognitive development have been considered irreversible beyond early childhood there is a lack of consensus in the literature on this, as there is some evidence of recovery from stunting and that this...
OBJECTIVES: To assess and quantify the magnitude of inequalities in under-five child malnutrition, particularly those ascribable to socio-economic status and to consider the policy implications of these findings. METHODS: Data on 3765 under-five children were derived from the Living Standards and Development Survey. Household income, proxied by per capita household expenditure, was used as the ...
Background and Objective: One in every five children in developing countries are malnourished, and the poor nutrition is associated with half of all children deaths worldwide. The aim of current study was to assess the nutritional status of less than five-year children in Salmas district, using ENA (Emergency Nutrition Assessment) software. Materials and Methods: This cross-sectional s...
