We evaluated in situ rates of bacterial carbon processing in Amazonian floodplain lakes and mainstems, during both high water (HW) and low water (LW) phases (p < 0.05). Our results showed that bacterial production (BP) was lower and more variable than bacterial respiration, determined as total respiration. Bacterial carbon demand was mostly accounted by BR and presented the same pattern that BR...

background: the aim of the study was to research concerning the epidemiology of newborns' galactosemia during 2007-2008 to find out whether screening was necessary for iranian newborns or not and also what the symptoms of this disease before or after diet were. methods: the data were collected from 24000 newborn babies from fars province, southern iran. the enzymatic calori­metric test was done...

Background: Coconut water is one of the natural food products that widely available around world. This commodity provides nutritional content could increase rehydration status and improve health. The application coconut to health, including improving type 2 diabetes metabolism, has gotten research interest in recent years. Objectives: narrative review paper aimed summarize several articles abou...

Introduction: Choline uptake and metabolism is decreased in older adults. A decrease in cholinergic function is characteristic of both normal aging and agerelated diseases (e.g., Alzheimer disease). Interestingly, the intensity of the signal at 3.2 ppm in lH-MRS (“choline” signal) serves as a marker for several brain pathologies including brain tumors. This chemical shift is indicative of the N...

Previous work on the adaptation of maize (Zea mays) primary roots to water deficit showed that cell elongation is maintained preferentially toward the apex, and that this response involves modification of cell wall extension properties. To gain a comprehensive understanding of how cell wall protein (CWP) composition changes in association with the differential growth responses to water deficit ...

Growth and carbon (C) fluxes are severely altered in plants exposed to soil water deficit. Correspondingly, it has been suggested that plants under water deficit suffer from C shortage. In this study, we test this hypothesis in Arabidopsis (Arabidopsis thaliana) by providing an overview of the responses of growth, C balance, metabolites, enzymes of the central metabolism, and a set of sugar-res...

Chrysolaena obovata stores inulin in the rhizophores, associated with drought tolerance. While crop plants are widely studied concerning the interactive effects of high [CO2] and drought, few studies reported these effects in native species. Here, we evaluated the combined effects of these factors on water status and fructan metabolism in C. obovata, a native Cerrado species. Two lots of plants...

RADFORD, EDWARD P., JR. Factors modifying water metabolism in rats fed dry diets. Am. J. Physiol. 196(s) : 1098-I 108. I959*To determine dietary factors which govern water turnover in rats, water intake and output were studied during q-hour intervals. Rats given water ad libitum and Purina laboratory chow or a synthetic diet voluntarily maintained an antidiuretic state, restricting water intake...

Water deficit is the most important environmental constraint severely limiting global crop growth and productivity. This study investigated early transcriptome changes in maize (Zea mays L.) primary root tissues in response to moderate water deficit conditions by RNA-Sequencing. Differential gene expression analyses revealed a high degree of plasticity of the water deficit response. The activit...
