1-anilino-8-naphtalenesulfonate (ANS) is a hydrophobic dipole previously used to demonstrate that the proton for potassium exchange by the gastric HK-ATPase is electroneutral. In this paper, we demonstrate that ANS binds to gastric membranes and probes conformational changes of the HK-ATPase independently of any active H for K exchange. Conformational changes require the presence of potassium-valinomycin and are not triggered by sodium. Potassium effect is enhanced by ATP, in the presence and in the absence of magnesium and, by ADP, in the presence of magnesium. Labeling of the pig HK-ATPase K518 by fluorescein-5-isothiocyanate inhibits the enzyme activity and knocks out the ATP effect on ANS fluorescence. Scherring 28080 and the monoclonal antibody 95-111, two competitive inhibitors of K-activated ATPase dephosphorylation, do not modify K-effect on ANS fluorescence but inhibit ATP effects. This supports that ANS does not probe K-site between the H1-H2 loop. Treatment of gastric membranes with trypsin does not inhibit the ANS response to potassium but does inhibit the response to ATP. This suggests that the ATP site inducing the ANS response is cytoplasmic and the potassium site is intramembranous. Titration reveals that one mole of ANS interacts with one mole of ATPase. We suggest that ANS probes a hydrophobic potassium site of gastric ATPase and that addition of ATP and ADP-Mg embed that site. [less ▲]

79 women who had been menopausal for less than 36 months and who had not received any form of treatment to prevent bone loss were randomly assigned to a 12-month regimen of calcium 500 mg/day or calcium 500 mg plus intranasal salmon calcitonin 50 IU/day for 5 days per week. After 12 months of treatment bone mineral density had decreased in the calcium-only group by a mean of 3.16 (SEM 0.6)% (p less than 0.01) but had increased in the calcium plus calcitonin group by 1.38 (0.8)% (NS). The difference in response between the two treatment groups was also highly significant (p less than 0.01), as was the difference between values for hydroxyprolinuria/creatininuria (p less than 0.01). Endogenous calcitonin levels rose significantly in the calcium group but remained unchanged in calcitonin-treated patients. Treatment by calcitonin and calcium was not followed by increased secretion of parathyroid hormone. The findings suggest that intranasal calcitonin can counteract early postmenopausal bone loss.

The challenges facing sustainable development are essentially human-based; human society has mainly created or exacerbated many human problems such as poverty and food security as well as natural environment problems, such as climate change and climate extremes. In addition, the eventual solutions must be elaborated and put into place by various actors. Thus it is essential to have a thorough understanding of actor dynamics … the interests of different actors, interactions between them and the initiatives that they engage in. A framework is presented to help any observer and researcher in any cultural or territorial context to understand the challenges facing the involvement of actors and human society in general in any search for sustainable development, and this is so for the countries of the North and the South. We then explore how a better understanding of actor dynamics support those researchers who wish to make a substantial contribution to resolving these challenges and helping populations move closer towards a sustainable future for their communities and environments. It is argued that one of the most pertinent ways for researchers to do this is through the various research approaches termed action research; it is argued that with patience and playing out the roles of counselor, facilitator, and provider of strategic information, action research, particularly Participatory Action Research (PAR) can achieve significant progress towards a sustainable future.

The precise location of banks considered favourable for kingfisher nesting are rare: six for nesting in 1999. In addition, the location of former banks that have been rendered unsuitable was accompanied by a brief summary of their condition and recommendations for their conservation or restoration. The two main problems are, on the one hand, trampling by livestock and, on the other hand, interventions to stabilise the banks by adding various materials at the foot of the bank or by more elaborate arrangements.

In this work, we study the non-linear dynamic response of two vertically-arranged aero-piezoelastic harvesters. The numerical framework consists of the following: i) an aerodynamic model based on the unsteady vortex-lattice method; ii) a three degree-of-freedom lumped-parameter model for each harvester; iii) an inter-model connection to exchange information between models at each time step; and iv) a numerical scheme based on Hamming’s fourth-order predictor–corrector method to integrate all the governing equations. Particularly, the effect of nonlinear hardening/softening springs on the harvested output power is investigated. Among the results obtained, an interesting finding is that hardening springs yield larger LCO amplitudes and higher harvested power than softening springs. [less ▲]
