In this paper, the Timoshenko beam theory is developed for bending analysis of functionally graded beams having porosities. Material properties are assumed to vary through the height of the beam according to a power law.

The photo catalytic efficiency of some TiO2 films (TiO2-ST01; TiO2-P25; TiO2 sol-gel) immobilized on glass has been investigated for the degradation of phenol in aqueous solution under UV light. It was shown that the best result obtained with TiO2-ST01 film, where the mineralization was the highest (70% TOC was removed after 3 hours of irradiations) and that related to the smaller particle size and the bigger surface areas of the TiO2-ST01 particles compared with TiO2-P25 and TiO2 sol-gel films. The effect of pH and phenol concentration were discussed.

We investigated the role of electrostatic charges at positions D72 and K8 in the function and structural stability of cytochrome c6 from Nostocsp. PCC 7119 (cytc6). A series of mutant forms was generated to span the possible combinations of charge neutralization (by mutation to alanine) and charge inversion (by mutation to lysine and aspartate, respectively) in these positions.

Endotoxin-neutralizingprotein (ENP) of the horseshoe crab isoneof themost potent neutralizersof endotoxins [bacterial lipopolysaccharide (LPS)]. Here, we report on the inter-action of LPS with recombinant ENP using a variety of physical and biological techniques. In biological assays (Limulusamebocyte lysate and tumour necrosis factor-a induction in human mononuclear cells), ENP causes a strong reduction of the immunostimulatory ability of LPS in a dose-dependent manner.

We have shown that the ABC transporter, multiple drug resistance protein 1 (MDR1, P-glycoprotein) translocates glucosyl ceramide from the cytosolic to the luminal Golgi surface for neutral, but not acidic, gly-cosphingolipid (GSL) synthesis. Here we show that the MDR1 inhibitor, cyclosporin A (CsA) can deplete Gaucher lymphoid cell lines of accumu-lated glucosyl ceramide and Fabry cell lines of globotriaosyl ceramide (Gb3), by preventing de novosynthesis.
