In our study, poly(dl-lactide-co-glycolide) (PLGA) nanoparticles loaded with perphenazine (PPH) and chlorpromazine hydrochloride (CPZ-HCl) were formulated by emulsion solvent evaporation technique. The effect of various processing variables, including PLGA concentration, theoretical drug loading, poly(vinyl alcohol) (PVA) concentration and the power of sonication were assessed systematically to...

The development of tumor-selective radiopharmaceuticals is clinically desirable as a means of detecting or confirming the presence and location of primary and metastatic lesions and monitoring tumor response to (chemo)therapy. In addition, the application of targeted radiotherapeutics provides a unique and effective modality for direct tumor treatment. In this manner the radioimmunotherapy (RIT...

INTRODUCTION Many reports in literature have underlined particular features of Lactobacillus paracasei subsp paracasei F19, however a critical review of main clinical outcomes has not been performed so far. OBJECTIVES This review summarizes the most relevant reports, in terms of clinical benefits, of Lactobacillus paracasei subsp paracasei F19 administration reviewing it’s historical backgrou...

Cabozantinib, a potent pan-tyrosine kinase inhibitor, has been reported to provide enhanced antitumor efficacy by simultaneously inhibiting both MET and VEGF pathways, which are critical to tumor angiogenesis, survival and migration. It's very poor water solubility prevents its administration by the intravenous route, which may be important in patients unable to take the drug orally. In this st...

Ocular drug delivery systems suffer from rapid drainage, intractable corneal permeation and short dosing intervals. Transcorneal drug permeation could increase the drug availability and efficiency in the aqueous humor. The aim of this study was to develop and optimize nanostructured formulations to provide accurate doses, long contact time and enhanced drug permeation. Nanovesicles were designe...

The stability of a moisture-sensitive drug in lyophilized products was investigated under conditions with varying water content and temperature using two model formulations: a formulation containing inositol (IF) as the excipient and a formulation containing mannitol (MF) as the excipient. IF showed better chemical stability (a lower hydrolysis rate) than MF when both formulations contained 2% ...

Viability and metabolism of Staphylococcus aureus after freezing, lyophilization, and gamma irradiation. J. Bacteriol. 88:545-552. 1964.-Reproductive viability and oxidative activity on various substrates (alanine, glutamic acid, glucose, lactic acid) were studied in Staphylococcus aureus c...

A major problem of current vaccines is storage stability, often requiring strict maintenance of cold chains. In the course of the eradication of smallpox, a freeze-dried vaccinia virus (Dryvax), which proved to be very stable, was used to overcome this limitation. However, Dryvax needs to be reconstituted before usage and is administered using a bifurcated needle, procedures that pose a number ...
