Abstract:

[2-14C]Urate uptake and efflux were studied in brush border and basolateral membrane vesicles of rat renal cortex that were exposed to 20 microM copper chloride. In the presence of inwardly directed NaCl gradients urate uptake was maintained at levels in excess of chemical equilibrium. Comparison of glucose and chloride uptakes revealed that equilibrium glucose uptake was not affected by copper, but chloride failed to reach equilibrium in copper-exposed vesicles. It is suggested that the persistence of an electrolyte gradient could provide a driving force to raise the concentration of free int

Abstract Penicillium brevicompactum, Copper Uptake, Kinetics The copper binding properties of Penicillium brevicompactum biomass were influenced by growth phase of mycelium and concentration of copper in reaction mixtures. The efficiency of copper uptake increased with growth time and was largest at the mid-logarithmic growth phase. The time course of copper uptake was biphasic. Double reciprocal plots of absorption velocity of copper vs. copper concentration gave straight lines at concentration between 0.5 to 4 mᴍ .

Abstract:

The plasma-membrane of Saccharomycescerevisiae contains high affinity permeases for Cu(I) and Fe(II). A low affinity Fe(II) permease has also been identified, designated Fet4p. A corresponding low affinity copper permease has not been characterized, although yeast cells that lack high affinity copper uptake do accumulate this metal ion. We demonstrate in the present study that Fet4p can function as a low affinity copper permease. Copper is a non-competitive inhibitor of 55Fe uptake through Fet4p (Ki = 22µM). Fet4p-dependent 67Cu uptake was kinetically characterized, with Km and Vmax values of

Abstract:

Copper is a commonly used metal in construction, engineering, agriculture and water treatment. Consequently, increased copper concentrations resulting in adverse environmental effects is inevitable. Phytoremediation using Dendrocalamus asper or Philippine giant bamboo (PGB) is a viable option for treatment of copper-contaminated media, but their copper uptake potential remains largely unexplored. As such, the copper uptake of PGB was evaluated under varying environmental conditions, namely initial copper concentration, water hardness and pH.Six-month old propagules were planted in artificially

SUMMARYSeveral components of branchial copper uptake were identified in juvenile freshwater rainbow trout (Oncorhynchus mykiss) using 64Cu. On the basis of competitive interactions between sodium and copper uptake,inhibition of copper uptake by a proton pump inhibitor (bafilomycin A1, 2μmol l-1) and a Na+ channel blocker (phenamil, 100μmol l-1), it appears that a proportion of the branchial copper uptake occurs via an apical Na+ channel. This sodium-sensitive copper uptake demonstrates saturation kinetics, with a Km of 7.1 nmol l-1 and a Jmax of 21.2 pmol g-1 h-1, and is characterized by an IC

Abstract:

The effect of the herbicide chlorsulfuron on the uptake and utilization of copper and zinc by wheat was examined in a series of glasshouse experiments. Application of chlorsulfuron induced symptoms of both copper and zinc deficiencies, and decreased copper and zinc concentrations within shoots. Chlorsulfuron accentuated deficiencies of copper and zinc by decreasing uptake of the micronutrients rather than by affecting their utilization within the plant. Effects of chlorsulfuron in decreasing uptake of copper and zinc did not appear to be due to effects on root weight or root length. However, c

Abstract:

Ionic copper entering blood plasma binds tightly to albumin and the macroglobulin transcuprein. It then goes primarily to the liver and kidney except in lactation, where a large portion goes directly to the mammary gland. Little is known about how this copper is taken up from these plasma proteins. To examine this, the kinetics of uptake from purified human albumin and α2-macroglobulin, and the effects of inhibitors, were measured using human hepatic (HepG2) and mammary epithelial (PMC42) cell lines. At physiological concentrations (3–6 μM), both cell types took up copper from these proteins i

The accumulation of copper over 2 h by normal lymphoid cells and those from Menkes'-disease patients (Menkes' cells) was found to be biphasic, with an initial phase of rapid uptake, an approach to steady state at around 40-60 min, followed by a further accumulation phase. The accumulation of copper was not diminished by the addition of a variety of metabolic inhibitors, suggesting that copper uptake is not an active process. The presence of carbonyl cyanide m-chlorophenylhydrazone in the culture medium stimulated the uptake and accumulation of copper in both normal and Menkes' cells to the sam

Prion protein (PrPC) is a cell surface glycoprotein, anchored by the GPI to the cell membrane.

Many cellular functions were proposed as PrPC roles, such as the modulation of several signal transduction pathways known to promote cellular survival and the protection against oxidative stress. Nevertheless, the main hypothesis on PrPC role is in copper homeostasis. Copper is an essential micronutrient (EMN) and all EMNs (vitamins and metals) are present in bodies and foods in micro

Copper oxide nanoparticles (NPs) are used in an expanding range of industries including a potential for agricultural applications as a fungicide.

Many of these chemicals are metal chelators that may increase the solubility of CuO NPs, thus enhancing the impact of these NPs on plants.

Abstract:

Stormwater management is an ongoing challenge in the United States and the world at-large. As state and municipal agencies grapple with conflicting interests like encouraging land development, complying with permits to control stormwater discharges, “urban stream syndrome” effects, and charges to steward natural resources for the long-term, some agencies may turn to constructed wetlands (CWs) as aesthetically pleasing and functional natural analogs for attenuating pollution delivered by stormwater runoff to rivers and streams. Constructed wetlands retain pollutants via common physical, physico

Abstract:

The overall goal of this project was to elucidate the role of dissolved organic matter (DOM) in soil retention, bioavailability and plant uptake of silver and cerium oxide NPs. The environmental risks of manufactured nanoparticles (NPs) are attracting increasing attention from both industrial and scientific communities. These NPs have shown to be taken-up, translocated and bio- accumulated in plant edible parts. However, very little is known about the behavior of NPs in soil-plant system as affected by dissolved organic matter (DOM). Thus DOM effect on NPs behavior is critical to assessing the

Abstract:

This paper analyzes the impact of the Farm Modernization and Development Program (PREDEG) on the technology uptake and productivity of Uruguayan farmers. Using a unique panel dataset, the authors combine propensity score matching techniques and fixed effects models to estimate the program's impact. Although the results vary according to the crops, the authors find consistent evidence that the program increased the rate of adoption of certified varieties and the density of plantation. However, there is only limited evidence of its effects on productivity, mostly derived from helping producers t
