Abstract
Diabetic retinopathy is a public health issue and the leading cause of blindness in adults in industrialized countries. Many advances have been made during the last few years in the diagnosis, the understanding of the pathophysiology and the treatment of diabetic retinopathy, especially with the rise of anti-angiogenic treatments. We bring here an overview of the last advances, the current therapeutic algorithms and future perspectives.

Abstract
Claims about molecular mechanisms underlying the resistance to anti-hormones of prostate cancer cells find support in biological experiments, which involve hormone-independent activation of the androgen receptor's (AR) transcriptional activity. In order to test this hypothesis, we attempted to shut down the expression of AR by the means of target-directed antisense oligonucleotides. A set of 49 oligonucleotides matching sequences of the AR mRNA either in the coding sequence or in the 3' and 5' untranslated regions were synthesized and examined in a cellular AR-dependent reporter system. Five antisense oligonucleotides were identified as highly potent inhibitors of AR-driven gene expression in a cellular reporter assay. These five were further profiled using point-mutated control sequences for the assessment of AR inhibition. In addition the expression of another AR-driven gene, the modulator of PSA expression (gene for inhibition of prostate specific antigen, an endogenous, AR-driven gene) was examined. Finally, we observed that the hormone-independent but AR-mediated transactivation by IGF-1 could also be specifically shut-down by these antisense oligonucleotides. The selection of highly target-restricted antisense oligonucleotides in the prostate cancer cell line LNCaP provided tools to study a central role of the androgen receptor in growth regulation of prostatic cancer cell lines and could be of utility in cancer situations in vivo.

Abstract
Thermal growth of silicon oxide films on silicon carbide in O2 was investigated using oxygen isotopic substitution and narrow resonance nuclear reaction profiling. This investigation was carried out in parallel with the thermal growth of silicon oxide films on Si. Results demonstrate that the limiting steps of the thermal oxide growth are different in these two semiconductors, being diffusion limited in the case of Si and reaction limited in the case of SiC. This fact renders the growth kinetics of SiO2 on SiC very sensitive to the reactivity of the interface region, whose compositional and structural changes can affect the electrical properties of the structure.

Abstract
The morphological expression of keratinolysis in fungi isolated from the air of Torino (98 isolates belonging to 36 species) was studied. Light microscopy on whole material and on semithin sections, as well as scanning electron microscopy was used. There were 19 keratinolytically active species, with seven in the genus Chrysosporium (C. indicum, C. keratinophilum, C. pannicola, C. tropicum, C. an. Arthroderma cuniculi, C. an. Pectinotrichum llanense, C. an. Renispora flavissima), four in the genus Malbranchea (M. arcuata, M. fulva, M. sulphurea, M. st. Uncinocarpus reesii), and three in the genus Trichophyton (T. mentagrophytes, T. rubrum, T. terrestre). In addition there were Aphanoascus fulvescens, Beauveria bassiana, Geomyces pannorum v. pannorum, Gymnoascus umbrinus and Myceliophthora vellerea. Most of these species were capable of developing structures related to surface erosion and radial penetration contemporaneously. However Gymnoascus umbrinus, Myceliophthora vellerea, an isolate of C. indicum, C. tropicum and Trichophyton mentagrophytes demonstrated only surface erosion. Different isolates of one species can vary in their production of invasive structures and in degree of keratinolytic activity. Thus such activity, like many biochemical activities of fungi, does not appear to be a constant or rigorously species-specific character.
