This manuscript reviews the current knowledge on the main classes of pathogenic Escherichia coli in dogs and cats: type 1 necrotoxigenic strains (NTEC1), adhesin-positive strains (AdEC), enteropathogenic strains (EPEC) and enterotoxigenic strains (ETEC). They represent primary or secondary (to other bacterial, parasitic and/or viral infections) infectious agents. NTEC1 and AdEC are the most frequent and are responsible for intestinal, urinary tract and invasive infections, while EPEC and ETEC limit their infections to the intestinal tract. ETEC are the less frequent but EPEC are more and more often observed. The specific virulence factors and other properties of these pathogenic E. coli strains are similar to those of their bovine, human and porcine counterparts, for their identity and their genetic determinism. This similarity allows the use of an identical approach in their diagnosis and typing. But for some NTEC1, AdEC and EPEC strains the similarity is so close that it also raises the question of their zoonotic potential, though there is up to now no epidemiological evidence of such cross contamination of man by canine or feline pathogenic E. coli (or vice versa).

Inclusion Complexes of Cyproterone Acetate with Cyclodextrins in Aqueous Solution

Cyproterone acetate (CPA) is a steroidal antiandrogen with a progestogenic activity. Given that this molecule has a very poor water solubility (2.1 μg/mL), different cyclodextrins (CDs) were tested to form inclusion complexes and to increase solubility. Two different techniques were compared to study the affinity between CPA and CDs: phase-solubility studies and NMR spectroscopy. The stoichiometry and the stability constant could be determined for most complexes with the aid of phase-solubility studies. The greatest increase in solubility was achieved with the methylated β-CDs, but hydroxypropylated β- and γ -CDs also gave enhanced solubilities. 1H-NMR studies showed a solubility increase similar to that found with phase-solubility studies. The proof of inclusion in the 2,6-dimethyl-β-CD (DIMEB) was shown by 1H-NMR and t-ROESY spectra. [less ▲]

All living systems have evolved mechanisms to maintain homeostasis in the face of rapid environmental changes. When exposed to elevated temperatures, most of the cells activate the synthesis of a specific group of proteins called Heat Shock Proteins (Hsps). This heat shock response, under control of specific transcription factors, the Heat Shock factors (HSF), is an evolutionarily conserved mechanism, from bacteria to humans. Heat Shock Proteins are classified into families according to their molecular weight (Hsp 25, 40, 70, 90, 105). They play the role of molecular chaperones by binding and protecting other molecules (proteins, RNAs). The function of Hsp is to prevent accumulation of non-native proteins either by assisting proper folding of polypeptides or by driving them to proteosome pathway for degradation. Hsps are involved in various pathological processes that are accompanied by protein alterations such as chronic or degenerative diseases. This review describes structural and functional characteristics of the six main Hsps classes. It also focuses on their respective role in highly studied pathologies. The diversity of Hsps implications in these diseases explains that they became recently a strategic target in development of new therapeutic strategies. [less ▲]
