Several chemical entities have shown their ability to reduce axial and/or appendicular fractures in patients with osteoporosis. Since patients who have experienced a previous fracture are at high risk for subsequent vertebral or hip fracture, it is of prime importance to treat such patients with medications that have unequivocally demonstrated their ability to reduce fracture rates in patients with prevalent fractures. Results obtained with calcium and vitamin D, in this particular population, are not fully satisfactory and these medications are probably better used in conjunction with other therapeutic regimens. Bisphosphonates have shown their ability to reduce vertebral (alendronate, risedronate, ibandronate) and non-vertebral (alendronate, risedronate) fractures in patients with established osteoporosis. Raloxifene has also shown similar properties, notwithstanding its effect on non-vertebral fractures, which has only been derived from a post hoc analysis limited to patients with prevalent severe vertebral fractures at baseline. This compound also has interesting non-skeletal benefits, including effects on the breast and heart. Teriparatide, a bone-forming agent, promptly reduces the rate of vertebral and all non-vertebral fractures, without significant adverse effects. Strontium ranelate, the first agent shown to concomitantly decrease bone resorption and stimulate bone formation, has also shown its ability to reduce rates of vertebral and non-vertebral fractures in patients with established osteoporosis. It significantly reduces hip fractures in elderly individuals at high risk for such events. Its safety profile is also excellent. [less ▲]

Complex mineralogy combined with a variable chemistry lead to various flotation responses of cobalt oxy-hydroxides present in oxidised and mixed copper-cobalt stratiform deposits of the Central African Copperbelt. Optimum metallurgical results require very high dosages of reagents and the management of such high chemicals concentrations in the pulp at the plant scale is delicate. The transition period between high reducing conditions during the sulfidisation step and a more oxidising environment prevailing during collector adsorption is particularly critical. This paper demonstrates how the use of copper and cobalt complexing agents can significantly improve the process control and metallurgical performance. The different modes of action of these reagents are presented and mechanisms for the various reactions proposed. Plant results following the introduction of ammonium sulfate at the New Concentrator of Kipushi are discussed. [less ▲]

BACKGROUND: It is unknown whether the duration of systemic immunosuppressive treatment after allogeneic nonmyeloablative hematopoietic cell transplantation (HCT) might influence the incidence, severity, timing, and/or corticosteroid-responsiveness of graft-versus-host disease (GVHD). METHODS: We retrospectively analyzed outcomes among 185 patients with hematologic malignancies who were given grafts from HLA-matched related donors following conditioning with 2 Gy total body irradiation alone or in combination with fludarabine between December 1998 and March 2003. Postgrafting immunosuppression consisted of mycophenolate mofetil (days 0-27) in combination with 3 different cyclosporine (CSP) regimens: taper from (A) days 35 to 56 (n=107), (B) days 56 to 77 (n=35), and (C) days 56 to 180 (n=43). RESULTS: The overall incidences of grades II-IV and III-IV acute GVHD, and extensive chronic GVHD were 52%, 13%, and 56%, respectively. The duration of CSP prophylaxis did not significantly influence the overall rate of acute GVHD (grade II-IV), extensive chronic GVHD, or non-relapse mortality. However, prolonged administration of CSP (group C) was associated with a significantly decreased hazard of grades III-IV acute GVHD (HR 0.2, 95% CI [0.04, 0.9]) and with an increased likelihood of discontinuing all systemic immunosuppression (HR 2.4, 95% CI [1.1, 5.2]) when compared to the shortest course of CSP (group A). CONCLUSION: Longer CSP duration decreased the risk of severe GVHD and increased the likelihood of discontinuing all systemic immunosuppression after nonmyeloablative HCT with HLA-matched related grafts.

We herein demonstrate that in the Holstein-Friesian dairy cattle population, microsatellites are as polymorphic on the X chromosome as on the autosomes but that the level of linkage disequilibrium between these markers is higher on the X chromosome than on the autosomes. The latter observation is not compatible with the small male-to-female ratio that prevails in this population and results in a higher gonosomal than autosomal effective population size. It suggests that the X chromosome undergoes distinct selective or mutational forces. We describe and characterize a novel Markovian approach to exploit this linkage disequilibrium to compute the probability that two chromosomes are identical-by-descent conditional on flanking marker data. We use the ensuing probabilities in a restricted maximum-likelihood approach to search for quantitative trait loci (QTL) affecting 48 traits of importance to the dairy industry and provide evidence for the presence of QTL affecting 5 of these traits on the bovine X chromosome.

Firstly, in this paper the historical analysis of volition as a specific construct in front of motivation and conation is developed. From the middle of the eighties volition is focused in empirical literature as a central concept in goal-directed learning behaviours, especially when goals are difficult to reach. Secondly, limits of motivation (values, expectations) to explain reaching complex learning goals which imply overcoming internal or external obstacles are heightened and volition (action control strategies and implementation intentions) is proved to basically contribute to initiate goal-directed actions and bring them to a successful conclusion.

Rift valley fever (RVF) is an arboviral disease produced by a bunyavirus belonging to the genus Phlebovirus. Several species of Aedes and Culex are the vectors of this virus that affects sheep, goats, buffalos, cattle, camels and human beings. The human disease is well known, especially during periods of intense epizootic activity. The initial description of the disease dates back to 1930, when animals and human outbreaks appeared on a farm in Lake Naivasha, in the Great Rift Valley of Kenya. Until 2000, this disease was only described in Africa, and then outbreaks were also declared in the Kingdom of Saudi Arabia (2000-2001 and 2004) and in Yemen (2000-2001). Animal and human cases were recorded. This work presents a retrospective summary of the data collected on animal RVF cases during this epidemic in Yemen. Results from several RVF surveys were gathered from the Yemeni vet services and FAO experts. Geographical data (topographic maps and data freely available on internet) were used for the location of outbreaks. After cleaning and standardization of location names, all the data were introduced into a GIS database. The spatial distribution of outbreaks was then studied at two scales: at the national level and at a local scale in the particular area of Wadi Mawr in the Tihama plain, Western coast of Yemen.

The objective of this study was to do an exercise in risk assessment on Campylobaeter spp. for poultry based meat preparations in Belgium. This risk assessment was undertaken on the demand of the competent national authorities as one of the supportive factors to define fisk-based microbiological criteria. The quantitative risk assessment model follows a retail to table approach and is divided in different modules. The contamination of raw chicken meat products (CMPs) was represented by a normal distribution of the natural logarithm of the concentration of Campylobacter spp. (In[Camp]) in raw CMPs based on data from surveillance programs in Belgium. To analyse the relative impact of reducing the risk of campylobacteriosis associated with a decrease in the Campylobacter contamination level in these types of food products, the model was run for different means and standard deviations of the normal distribution of the ln[Camp] in raw CMPs. The limitation in data for the local situation in Belgium and on this particular product and more precisely the semi-quantitative nature of concentration of Campylobacter spp. due to presence/absence testing, was identified as an important information gap. Also the knowledge on the dose-response relationship of Campylobacter spp. was limited, and therefore three different approaches of dose-response modelling were compared. Two approaches (1 and 2), derived from the same study, showed that the reduction of the mean of the distribution representing the ln[Camp] in raw CMPs is the best approach to reduce the risk of Campylobacter spp. in CMPs. However, for the simulated exposure and approach 3 it was observed that the reduction of the standard deviation is the most appropriate technique to lower the risk of campylobacteriosis. Since the dose-response models used in approach I and 2 are based on limited data and the reduction of the mean corresponds with a complete shift of the contamination level of raw CMPs, demanding high efforts from the poultry industry, it is proposed to lower the standard deviation of the concentration of Campylobacter spp. in raw CMPs. This proposal corresponds with the elimination of the products that are highly contaminated. Simulation showed that eating raw chicken meat products can give rise to exposures that are 10(10) times higher than when the product is heated, indicating that campaigns are important to inform consumers about the necessity of an appropriate heat treatment of these type of food products.
