This paper presents a statistical model used to forecast fog in the Meuse Valley in Belgium. The method is a bootstrap discriminant analysis using eight predictors: river surface temperature, air pressure, air temperature at two elevations, wind speed and relative humidity at the same two locations. These data are measured from November 1989 to April 1990. Tests are done to determine the number of resampling needed for this data set and the optimum projection delay for prediction from the meteorological data. The best results are obtained for the prediction at 0700h UT using meteorological data at 0400 h UT. [less ▲]

En 2000, Henri Mayr-Harting contesta l’idée qu’Arnold Angenendt se faisait de la religion de Charlemagne . Au modèle d’une religion magique, essentiellement propitiatoire, il opposa un certain génie éthique carolingien teinté de quelques supports quasi-magiques et posa les jalons d’une enquête sur le sens profond de la religion de Charlemagne, son contenu éthique et son objet. Tout en admettant qu’on ne connaîtrait jamais les convictions personnelles de Charlemagne, il a avancé l’hypothèse qu’on était en mesure d’entendre sa voix dans certains documents faisant échos à un débat qui aurait opposé différents membres de la cour. Confortée par les recherches d’Henry Mayr-Harting, cette conférence visait à évaluer la sincérité des convictions religieuses de celui qui déploya tous les moyens matériels, militaires et humains qu’il avait à sa disposition, pour enseigner à son peuple ce qu’il était nécessaire de croire pour être sauvé.

Rett syndrome was associated with low cerebrospinal fluid (CSF) 5-methyltetrahydrofolate (5MTHF) in 42-50% of European patients whereas approximately 93% of the patients from North-America had a normal CSF 5MTHF status. We determined the CSF folate status in Rett patients living in North- and South-Western Europe and measured serum folate receptor (FR) autoantibodies of the blocking type to explain the reduced folate transport across the choroid plexus. Irrespective of their MECP2 genotype and despite normal plasma folate values, 14 of 33 Rett patients (42%) had low CSF folate levels. Blocking FR autoantibodies were found in 8 of the Rett patients (24%), 6 of whom had low CSF folate levels. FR autoimmunity was primarily found within the group of Rett patients with low CSF folate status with a higher incidence in North-Western Europe. In Rett patients from North-America 74 of 76 girls had higher folate values in both serum and CSF than European patients. The food folate fortification in North-America may account for the higher folate levels and may prevent CFD in these Rett patients. FR autoimmunity occurred predominantly in Rett patients from North-Western Europe and may contribute to cerebral folate deficiency (CFD). © Georg Thieme Verlag KG Stuttgart. [less ▲]

Reduced folate transport to the CNS was identified in two autism spectrum disorders, i.e., Rett syndrome and infantile low-functioning autism with neurological abnormalities. Twenty-five patients with early-onset low-functioning autism with or without neurological deficits, were evaluated for serum folate, cerebrospinal fluid (CSF) 5-methyltetrahydrofolate (5MTHF), and serum FR autoantibodies of the blocking type to determine the significance of folate receptor (FR) autoantibodies with respect to folate transport across the blood-CSF barrier. In spite of normal serum folate, CSF 5MTHF was low in 23 of 25 patients. The reduced CSF folate in 19 of these 23 patients could be explained by serum FR autoantibodies blocking the folate binding site of the membrane-attached FR on the choroid epithelial cells. Oral folinic acid supplements led to normal CSF 5MTHF and partial or complete clinical recovery after 12 months. Serum FR autoimmunity appears to represent an important factor in the pathogenesis of reduced folate transport to the nervous system among children with early-onset low-functioning autism associated with or without neurological deficits. Early detection of FR autoantibodies may be a key factor in the prevention and therapeutic intervention among this subgroup of patients with autism. © Georg Thieme Verlag KG Stuttgart. [less ▲]

Class A β-lactamases have proved useful as model proteins in studying a wide variety of aspects of protein folding. We review those features that have shed light on kinetic intermediates that take part in folding, including some insight into the molecular basis of the kinetic and stable molten-globule states that have been identified. The contrast between the folding behaviour of PC1 and the two lactamase mutants, P54 and P2, can be attributed in some detail to changes in molecular conformation. The early, very rapid stages of folding of β-lactamases have been shown to be multiphasic, and an interesting intermediate is described that has non-native contacts involving burial of the C-terminal tryptophan. A further feature is that the region around the disulphide bond in the TEM enzymes is formed very early in the foldingreaction. The unusual feature of class A β-lactamases, i.e. a cispeptide bond critical in the stereochemistry of the active site that usually, but not always, involves a proline residue, has been shown to be important in accounting for the slow folding reactions. The effect of substrates on the stabilization of the enzymes and on their reversible deactivation is also reviewed. [less ▲]

Class A beta-lactamases (M(r) approximately 29000) provide good models for studying the folding mechanism of large monomeric proteins. In particular, the highly conserved cis peptide bond between residues 166 and 167 at the active site of these enzymes controls important steps in their refolding reaction. In this work, we analyzed how conformational folding, reactivation, and cis/trans peptide bond isomerizations are interrelated in the folding kinetics of beta-lactamases that differ in the nature of the cis peptide bond, which involves a Pro167 in the BS3 and TEM-1 enzyme, a Leu167 in the NMCA enzyme, and which is missing in the PER-1 enzyme. The analysis of folding by spectroscopic probes and by the regain of enzymatic activity in combination with double-mixing procedures indicates that conformational folding can proceed when the 166-167 bond is still in the incorrect trans form. The very slow trans --> cis isomerization of the Glu166-Xaa167 peptide bond, however, controls the final step of folding and is required for the regain of the enzymatic activity. This very slow phase is absent in the refolding of PER-1, in which the Glu166-Ala167 peptide bond is trans. The double-mixing experiments revealed that a second slow kinetic phase is caused by the cis/trans isomerization of prolines that are trans in the folded proteins. The folding of beta-lactamases is best described by a model that involves parallel pathways. It highlights the role of peptide bond cis/trans isomerization as a kinetic determinant of folding.

How a conformationally disordered polypeptide chain rapidly and efficiently achieves its well-defined native structure is still a major question in modern structural biology. Although much progress has been made towards rationalizing the principles of protein structure and dynamics, the mechanism of the folding process and the determinants of the final fold are not yet known in any detail. One protein for which folding has been studied in great detail by a combination of diverse techniques is hen lysozyme. In this article we review the present state of our knowledge of the folding process of this enzyme and focus in particular on recent experiments to probe some of its specific features. These results are then discussed in the context of the 'new view' of protein folding based on energy surfaces and landscapes. It is shown that a schematic energy surface for lysozyme folding, which is broadly consistent with our experimental data, begins to provide a unified model for protein folding through which experimental and theoretical ideas can be brought together.
