The spontaneous, dynamic formation of hydrophobic active sites in lipid bilayer membranes is studied and characterized. It is shown that the rates of formation and consumption of these active sites control at least two important properties of liposomes: their affinity for hydrophobic surfaces and the rate by which they spontaneously release encapsulated molecules. The adhesion and spreading of ...

The identification of pigs and cattle is currently based on a normal visual ear tag, but electronic animal identification is gaining in importance. The electronic identification of sheep and goats has been obligatory in the European Union since 2012. It is a question of time until this identification system becomes obligatory in other animal species, such as cattle and pigs. One possibility of ...

Background: Irritative symptoms including prolonged urgency and dysuria after GreenLight laser photoselective vaporization (PVP) of benign prostatic hyperplasia (BPH) are common complication. We aimed to compare the incidence of postoperative irritative symptoms of GreenLight XPS (GL-XPS) 180W laser system with GreenLight KTP (GL-KTP) 80W laser system for the treatment of BPH and evaluate the r...

The formation of membranes from two systems has been studied. In the system polyurethanedimethylformamide-water, the mechanism for the formation of the sponge-like structure proves to be a liquid-liquid phase separation with nucleation and growth of the diluted phase. This mechanism has been confirmed for the system modified polystyrene-polyisoprene-polystyrene/ o-dichlorobenzene/(methanol-wate...

A new in-house ambient pressure XPS (AP-XPS) was designed for the study of surfaces of materials under reaction conditions and during catalysis. Unique features of this in-house AP-XPS are the use of monochromated Al Kα and integration of a minimized reaction cell, and working conditions of up to 500 °C in gases of tens of Torr. Generation of oxygen vacancies on ceria and filling them with oxyg...

AIM Mineral trioxide aggregate (MTA) is the material of choice for apical barrier techniques during root canal treatment of teeth with open apices. However, the precise control of MTA during the placement of an apical plug is challenging. This article describes the outcomes of unintentional extrusion of MTA into the periradicular tissue during apical barrier treatment in three cases. SUMMARY ...

A series of polystyrene hybrid nanocomposites have been fabricated with varying amounts of TiO2 viz., 0, 0.5 and 1 % w/w along with 3% TS by in-situ polymerization method. The influence of surface modified TiO2 nanoparticles on the thermal properties of PS matrix was examined using thermogravimetry and differential scanning calorimetry. Thermal characteristics of the polystyrene/TS/TiO2 hybrid ...
