Insight into the interaction of quinizarin with SDS micelles - effects of additives.

Association behavior between quinizarin (1,4-dihydroxyanthraquinone), an analogue of the chromophore of anthracycline anticancer drugs and sodium dodecyl sulfate (SDS) micelles in the presence of glucose, NaCl and urea additives was studied using absorption spectroscopy and conductometric techniques. The spectral results indicate an increase of binding constant and partition coefficient values in the presence of glucose and NaCl whereas the addition of urea leads to a decrease of binding strength and quinizarin partitioning into SDS micelles. Thus, the rise of NaCl and glucose concentrations is favorable for the quinizarin distribution into SDS micelles.

Comparative Analysis of Left Ventricular Mass Regression Following Transcatheter Aortic Valve Implantation and Surgical Aortic Valve Replacement - a Single Center Experience from Romania.

Severe aortic stenosis is often associated with left ventricular hypertrophy (LVH). Elevated left ventricular mass (LVM) is linked to higher cardiovascular morbidity and mortality. Traditionally, surgical aortic valve replacement (SAVR) has been the standard treatment, but transcatheter aortic valve implantation (TAVI) offers an alternative for high-risk surgical patients.

Organ transplantation in Romania: challenges and perspectives.

Introduction: The interest in the field of organ transplantation and the first attempts at making experimental transplant interventions in Romania date from the very beginning of the 20th century. Nevertheless, the evolution of the donating activity and of organ transplantation in Romania has been confronted with a certain inconsistency and a lack of resources necessary to the development of the system.

Method: The aim of this study is to analyze the dynamics of the transplantation activity in Romania between 2000 and 2020.

Antibacterial Activity of ZnSe, ZnSe-TiO and TiO Particles Tailored by Lysozyme Loading and Visible Light Irradiation.

ZnSe, ZnSe-TiO microspheres and nanostructured TiO obtained by hydrothermal and sol-gel methods were tested against ATCC 25923 and ATCC 4698 before and after lysozyme (Lys) loading. Morphological characterization of inorganic matrices and hybrid organic-inorganic complexes were performed by microscopy techniques (SEM, AFM and Dark Field Hyperspectral Microscopy). Light absorption properties of ZnSe, ZnSe-TiO and TiO powders were assessed by UV-visible spectroscopy and their ability to generate reactive oxygen species (•OH and O) under visible light irradiation was investigated.
