One-dimensional hydrothermally synthesized nanostructures such as nanotubes and nanobelts composed of layered titanates from A2TinO2n+1 family have attracted great interest due to their high specific surface area, ion-exchange ability and semiconducting properties, which make them promising candidates for potential applications in the field of catalysis, gas sensors, dye-sensitized solar cells, …

Major histocompatibility complex (MHC) class II molecules are polymorphic cell surface glycoproteins expressed only on the surface of the professional antigen presenting cells and they play a crucial role in the adaptive immune responses. MHC class II molecules undergo a very complex maturation process. They are synthesized in the endoplasmic …

Plasma glutamate carboxypeptidase (PGCP) is a metalloproteinase. It is able to hydrolyze dipeptides into free amino acids. The enzyme is involved in the release of hormone thyroxin (T4) from Thyroglobulin (Tg), as suggested by thyroid gland studies. Prediction from the primary structure of human PGCP suggests the presence of five …

Titanium dioxide (TiO2) in nanoparticle form has recently gained a lot of attention, in both the scientific and industrial communities. This is due to the fact that it exhibits various interesting chemical and physical characteristics, for example, a high photocatalytic activity and the absorption of incident UV light. Many applications …

A new approach for the synthesis of silver (Ag), platinum (Pt) and gold (Au) nanoparticles and their composites with hydroxyapatite (HAp) is developed via a sonochemical process. The major goal was to design physicochemical properties of material in order to achieve: (i) intensive antibacterial activity and (ii) maximal reduction of …

With emerging need for orthopaedic implants and prolonged exposure of organism to implants also problems connected to elution of metal ions that in some cases cause adverse reactions in the human body, emerge. The main aim of our work was therefore to investigate the potential of silicon carbide (SiC) to …

The application of magnetic nanoparticles in biomedicine dictates the preparation of properly arranged nanoparticles. The preparation of a stable colloidal suspension of nanoparticles in complex biological media is a prerequisite for all types of applications. Depending on the type of application, the proper coating, functionalization and (bio)conjugation of the nanoparticles …

Adaptation to altitude can enhance performance if the hypoxic dose and the frequency of the exposures are appropriate. While many hypoxic training modalities exist, the protocols utilizing short intermittent hypoxic exposures are gaining popularity. However, the effects of such novel hypoxic protocols on athletic performance are unclear. The aim of …

Radon and its progeny play an important role contributing to the dose of radiation which a person receives from all natural sources of ionizing radiation. This is one of the reasons why this problem has been of great interest, as a result of which an increased number of scientific works …

The presence of insoluble amyloid aggregates in various human tissues correlates with the development of many human disorders (amyloidoses), including neurodegenerative diseases. Deposition of the aggregated misfolded proteins in the brain, where aggregates can be localized extracellularly or intracellularly, is the main characteristic of Alzheimer's, Parkinson's, Huntington's, prion diseases and …
