Glioblastoma (GBM) is the most common malignant neoplasm in adults among all CNS gliomas, with 5-year survival rate being as low 5%. Among nanocarriers, liposomal nanoformulations are considered a promising tool for precise drug delivery. The herein presented study demonstrates possibility of encapsulating four selected natural compounds (curcumin, bisdemethoxycurcumin, acteoside, and orientin) their mixtures cationic nanoformulation composed two lipid types (DOTAP:POPC). In order to...
Measurements of the Faraday rotation at room temperature over light wavelength range 300-680 nm for horse spleen ferritin (HSF), magnetoferritin with different loading factors (LFs) and nanoscale magnetite Fe(2)O(3) suspensions are reported. The magnetization materials studied present similar magnetic field dependences characteristic a superparamagnetic system. dependence on is described, excluding HSF Fe(2)O(3), by Langevin function log-normal distribution particle size allowing core...
Ferritins are proteins, which serve as a storage and transportation capsule for iron inside living organisms. Continuously charging the proteins with releasing it from ferritin is necessary to assure proper management of these important ions within organism. On other hand, synthetic ferritins have great potential biomedical technological applications. In this work, behavior during processes loading release was examined using multiplicity experimental technique. The quality protein's shell...
Bio-based composites made of poly(l-lactic acid) (PLLA) and pine wood were prepared by melt extrusion. The compatibilized impregnation with γ-aminopropyltriethoxysilane (APE). Comparison non-compatibilized formulation revealed that APE is an efficient compatibilizer for PLLA/wood composites. Pine particles dispersed within PLLA act as nucleating agents able to start the growth crystals, resulting in a faster crystallization rate increased crystal fraction. Moreover, have slightly lower...
In this paper we use a simple analysis based on properties of the axial field generated by symmetrical multipoles to reveal all possible distributions two coaxial pairs circular windings, which result in systems featuring zero octupole and 32 pole magnetic moments (six-order systems). Homogeneity selected is analyzed. It has been found that one derived generates homogenous whose volume comparable yielded eight-order system. The influence current distribution windings placement homogeneity...

Recent efforts in designing new 3H-naphthopyran derivatives have been focused on efficient coloration process with a short fading time of the colored transoid-cis TC isomer. It is desirable to avoid photoisomerization leading transoid-trans TT isomers photoreaction. Long lifetime can hamper fast applications such as dynamic holographic materials and molecular actuators, residual color one serious issues for photochromic lenses. Herein we characterize photophysical photochemical channels...
The design and construction of a high-performance, low-cost, easy to assemble adiabatic extension set for homebuilt commercial spectrometers is described.
