Knowing the potential therapeutic interest of AMPA potentiation, patents have been published for 15 years relating the discovery of novel compounds able to allosterically bind to the AMPA receptors and leading to a potentiation of the AMPA signals. Besides this classical approach, a new target for the medicinal chemist has been defined due to the recent findings describing the modulation of AMPA receptors by neuronal proteins, and has led to the design of dipyrazole compounds by Aventis. These new dipyrazole derivatives may be considered as `indirect AMPApams', constituting a new pharmacological class. Based on their in vitro activity, it is probable that these compounds could be of therapeutic value for the treatment of cognitive disorders, schizophrenia or depression. [less ▲]

Hip fracture is the major clinical consequence of osteoporosis. It is linked with decreased life expectancy and quality of life, placing an ever increasing burden on health services. Few medications have unequivocally demonstrated their ability to reduce hip fracture risk in osteoporotic subjects. Daily alendronate and risedronate reduce hip fracture in patients with low bone mineral density and prevalent vertebral fractures. Intravenous bisphosphonates have been developed, in response to long-term poor adherence to oral anti-osteoporotic treatments. Once-yearly zoledronic acid reduces fracture rates at the spine, non-spine and hip locations. Strontium ranelate, the first drug to uncouple bone formation from bone resorption has also demonstrated its ability to reduce hip fractures in patients above 74 years old, with prevalent low bone mineral density. Calcium and vitamin D supplementation are prerequisite for the management of elderly subjects and should always been associated to anti-resorptive or bone forming agents. Non-pharmacological management of osteoporosis is recommended cannot be considered a substitute for pharmacological treatment of osteoporosis, not even in old age. [less ▲]

The residual error is one of the most used criteria for the choice of regression model. The large majority of the criteria for model selection are also functions of the usual variance estimate for a regression model, as Akaike criterion information [Akaike, 1973] and Mallows’ criterion [Mallows, 1964]. The effectiveness of these criteria to approach the theoretical model is related to the good estimate of the theoretical residual error of the model. This efficiency is often limited by the sample size used for the estimates. The choice of a invalid model can have bad consequences on the objective of the research in particular on the forecasts, interpretations and the conclusions. We studied by Monte Carlo simulation the effects of the data structure on the quality of the residual error obtained in multiple linear regression. The results showed that the estimator is a good estimator when the model is established without selection of variables, but becomes biased when the model results from a selection of variables. Colinearity between the explanatory variables and the index which measure the importance of the variables in the true model do not have an influence on the quality of the estimator. [less ▲]

Despite 30 years of international regulations, Hg levels in marine mammals have not decreased. Various environmental models even suggest a rise of mercury in the biota during the next decades, linked to climate change. The objective of this study is (1) to assess Hg levels in blood samples of free-ranging pinnipeds, (2) to understand level variation during different periods of life (gestation, lactation, fasting) and potential impact on lymphocytes using a preliminary in vitro model (peripheral blood mononuclear cells, PBMC). Blood samples were collected from harbour seals (Phoca vitulina n= 22) from the North Sea and from elephant seals from the Californian coast (Mirounga angustirostris 12 females and 12 pups). Harbour seal PBMC were isolated, set in medium culture and contaminated with methyl-Hg (1 µM). Biological tests and proteomic assay were realized on control and contaminated PBMC. Hg levels were from the same order of magnitude for the two species despite two different lifestyles and habitats: from 40 to 590 ng.g-1 fw in harbour seal and from 63 to 919 ng.g-1 fw in elephant seal. Hg concentrations in the blood depend upon several factors such as body weight, fasting and lactation duration for mothers and pups. After 21 days of lactation, female elephant seals doubled their blood Hg levels (from 308 to 593 ng.g-1fw) while a decrease is observed for pups. This increase is linked to mobilization from blubber and muscle during fasting associated to lactation. Cell model revealed an in vitro effect of Hg even at low concentration (1µM). Number of PBMC, viability, metabolic activity, DNA and RNA synthesis were reduced in vitro suggesting deleterious effects of Hg in concentrations encountered in free-ranging pinnipeds. Knowing that Hg methylation in the ocean is linked to temperature, one can wonder on Hg levels (and effects) in pinnipeds during the next decades. [less ▲]

Research related to the prevention of business failure is surveyed in this paper. More specifically, the evolution of the accounting literature on business failure from a predictive to a preventive perspective is explained. After a clarification of the concept of business failure prevention, the main features of representative studies are presented and analysed. These studies are compared in terms of dynamics of the results proposed, of failure stage(s) studied, of conceptual approach privileged, of research object and of methodology used to obtain results. A typology of the research on business failure prevention is then proposed on the basis of two pertinent differentiating criteria: the dynamics of the contributions and the failure stage(s) taken into consideration. This paper finally stresses current limitations of business failure prevention literature, particularly the need for a consensus on how and why firms fail and the lack of investigation about typical failure profiles and paths. Potentialities for future progress in the field are discussed at the end of the paper. [less ▲]
