Abstract:
High concentrations of dissolved nutrients in stormwater have been identified as contributing to eutrophication of receiving waterways near urban areas. To reduce dissolved nutrient concentrations in stormwater a range of devices such as wetlands and bioretention systems are used. Bioretention systems are increasingly employed for their supposedly high nutrient removal capacity, however very little is known about their treatment efficiency or the chemical and biological mechanisms controlling their function. This research aimed firstly to test and compare the efficiency of different bioretenti

Abstract:
Nutrient sensing neurons are unique in coupling changes in the concentration of nutrients to changes in neuronal activity. These neurons typically exist in regions of the brain where the blood brain barrier is fenestrated, such as the arcuate nucleus of the hypothalamus. Glucose and leucine are nutrients known to be sensed by neurons in this brain region, but the mechanisms by which they are sensed, and cells that sense them require further study. Using calcium imaging of adult neuron cultures from the mouse mediobasal hypothalamus, I demonstrated that leucine bidirectionally regulates neurona

Moreover, the model is derived by using an analogy with the dissipation inequality and Coleman-Noll’s procedure. The model can be interpreted as bone or some other biological structure, where the

In conditions of phosphate deprivation, the budding yeast, Saccharomyces cerevisiae activates the phosphate starvation response pathway (PHO pathway). Induction of the PHO pathway causes the transcription of genes involved with phosphate metabolism. Phosphate transport genes are activated during starvation, giving rise to the presence of Pho84, the high affinity transporter. In high phosphate conditions low affinity transporters reside at the plasma membrane. Here we show that Spl2, a suppressor of phospholipase-C, is involved in the down-regulation of the low affinity transport system. T

The basic model is then extended to include root hairs and mycorrhizae, which have been found experimentally to be very important for the uptake of immobile nutrients. Again, analytic expressions for nutrient uptake are derived. The simplicity and clarity of the analytical

Background: Not only does IBD lead to nutritional deficiencies, but also nutrients influence its pathophysiology: exclusive enteral nutrition (EEN) is an effective primary treatment in Crohn's disease; and vitamin D (VitD) is involved in its pathogenesis and course. Aims: We hypothesised that nutrients impact on the course of IBD. We therefore studied the effect of EEN i) on long term clinical course in children; ii) on CD58, a costimulatory molecule at the intestinal epithelial cell (IEC) lines, iii) adults with Crohn's disease. We examined the possible effect of serum vitamin D levels on the

Abstract:
Thesis (MScAgric)--University of Stellenbosch, 2007.<br>ENGLISH ABSTRACT: The macro-element uptake and distribution by higher density central leader ‘Donnarine’ nectarine trees was studied through the sequential excavation of trees. A large portion, 41.5%, of the nitrogen manifested in the new growth from dormancy up to pit-hardening, originated from nitrogen reserves in the permanent structure. The permanent structure was also an important source of phosphorous reserves. Of the phosphorous in the fruit, leaves and new shoots at pit-hardening, 35.0% came from reserves in the permanent st
