In our study we examined thermosensitive liposomal formulations (TL) from the perspective to minimize the general toxicity drawbacks of chemotherapy. The TL become active in response to local hyperthermia (LH), and remain inactive at physiological conditions. Here, we formulated novel doxorubicin loaded thermoliposomes (Dox-TL) with optimized(More)
Aqueous dextran solutions, polyhexamethyleneguanidine hydrochloride and Sovidone and their mixtures with taurine were used to form stable ultrathin protective films for ophthalmological use. Addition of taurine to dextran and polyhexamethyleneguanidine solutions induced an association between polymer macromolecules in the two-dimensional film and a decrease(More)
Spread monolayers of the fibril protein collagen were studied at the air-water interface in the presence of denaturants, urea and thiourea. The most prominent feature of spread collagen monolayers at the air-water interface is the ability to form supramolecular structures (fibrils), which themselves can form monolayers with collapse points of their own. The(More)
A new approach to the formulation of eye drops containing the active substance taurine and adjuvant polymers such as dextran, poly(hexamethyleneguanidine) hydrochloride, and Sovidon is proposed. According to this, the eye drop formulation must begin with a study of the physicochemical properties of the polymer and taurine solutions, in particular an(More)
The incorporation of [5,6(n)-3H]prostaglandin A1 (PGA1) and [1-14C]oleic acid into membrane phospholipids of rat liver microsomes was studied. It was shown that PGA1 is incorporated into phospholipids in a much lesser degree than oleic acid. PGA1 is incorporated into phosphatidylethanolamine and, in a lesser degree, into phosphatidylcholine and(More)
