Spectroscopic and structural investigations of blue afwillite from Ma'ale Adummim locality, Palestinian Autonomy.

Until now, only the colourless crystals of mineral afwillite, Ca(HSiO)·2HO, were known from several localities around the world. Present work focuses on blue afwillite counterparts from the Ma'ale Adummim locality in Palestine. Using the wide spectrum of analytical methods we attempted to identify the causes of this unusual colour.

Experimental anticancer therapy with vascular-disruptive peptide and liposome-entrapped chemotherapeutic agent.

Vasculature is essential for the sustained growth of solid tumors and metastases. Tumor cells surviving vascular-disruptive therapeutic intervention (especially those present at the tumor rim) can contribute to tumor regrowth. The aim was to strengthen, by carrier-mediated delivery of a chemotherapeutic, the curative effects of a bifunctional anti-vascular oligopeptide capable of inducing vascular shutdown and tumor shrinkage.

Aromatic compounds in molecular phase of Baltic amber-synchronous luminescence analysis.

Synchronous luminescence analysis was performed in order to identify aromatic compounds in solvent extracts of Baltic amber. The investigated extracts were obtained, for comparisons, as products of extraction by various techniques and solvents. Methylene chloride and ethanol were applied independently for extraction at the ambient temperature (conservative extraction), as well as at the temperature of solvent boiling (extraction in Soxhlet apparatus).
