AB  - Malta, a country renowned for its honey, has not been extensively mentioned in studies based on honey. In addition to many parameters, the collection period affects honey quality, precisely due to the different floral composition that exists during a certain season. Therefore, the significance of this study refers to the provision of data on honey from Malta collected during the autumn, spring, and summer seasons. Melissopalynological analysis, determination of physicochemical parameters, and the use of analytical chromatographic methods enabled detailed analysis of this honey. Principal component analysis (PCA) provided the differentiation of Maltese honey depending on the harvest season. Lotus pollen, followed by Eucalyptus, predominated in all honey samples. Characteristic compounds for summer honey were pinocembrin, galangin, kaempferol, chrysin, p-hydroxybenzoic acid, vanillic acid and maltotriose, while quercetin 3-O-galactoside, ferulic acid, ellagic acid, protocatechuic acid, luteolin 7-O-glucoside and melibiose were specific for autumn honey. A higher amount of p-coumaric acid, genistein, catechin, as well as the content of many sugars were found in spring samples. To the best of our knowledge, this is the first scientific work dealing with a detailed chemical analysis of Maltese honey.

AB  - Surface characteristics and biocompatibility of new nanocomposites based on polyurethane network
and mesoporous silica nanoparticles (PUMSNs) were investigated. Surface topography and
roughness coefficient were studied by AFM. Biocompatibility with endothelial cells and cytotoxicity
of the PUNs were assessed using MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium
bromide) and cell adhesion assays. The addition of MSNs into polyurethane network led to
improvement of surface properties, as well as exhibited promising characteristics regarding adhesion
of cells, toward potential application in coating for medical devices.

AB  - Novel polyurethane nanocomposite (PUN) materials containing different surface-functionalized mesoporous silica nanoparticles (MSNs) were prepared by in situ polymerization methodology. Polyurethane network was formed from poly (dimethylsiloxane)-based macrodiol (PDMS), 4, 4′ -methylenediphenyldiisocyanate (MDI), and hyperbranched polyester of the second pseudo-generation (BH-20; used as crosslinking agent). PU and PU/MSN nanocomposites contained equal ratios of soft PDMS and hard MDI-BH-20 segments. Non-functionalized and surface-functionalized (with 3-(trihydroxysilyl) propyl methylphosphonate (FOMSN) and 2-[methoxy (polyethyleneoxy) 6-9propyl] trimethoxysilane (PEGMSN)) MSNs were used as the nanofillers at a concentration of 1 wt%. Prepared materials were characterized by Fourier transform infrared (FTIR) spectroscopy, atomic force microscopy (AFM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic mechanical thermal analyses (DMTA), nanoindentation, equilibrium swelling and water absorption measurements. Characteristics of the prepared PUNs when in contact with a biological environment were assessed through testing their biocompatibility, protein adsorption and adhesion of endothelial cells. The favourable influence of MSNs on the physico-chemical and biological characteristics of these novel PUN materials was identified, which evidences their vast applicability potential as coatings for medical devices and implants.

AB  - A focus of research in recent years is the comparison of honey as the final product of bees with pollen and nectar of the plant from which the honey originates, as the main food source for bees. Buckwheat honey is recognized as a nutritionally valuable product, which provides a scientifically proven health benefit and is confirmed as a functional food. The quality of this type of honey is attributed to high levels of phytochemicals in buckwheat. The purpose of this study was the examination of similarity between buckwheat honey and buckwheat nectar and pollen, as well as simultaneous investigation of their chemical profiles and the origin of the honey. The phenolic profile of buckwheat pollen showed a lower number of flavonoids and phenolic acids than those of nectar and honey samples, but confirmed the presence of the most characteristic polyphenols derived from the buckwheat plant. The notable difference was found to be the presence of (epi)catechin units, its galloylated derivatives and procyanidin dimers, which were not present in honey. Honey polyphenols displayed a pronounced correlation with those of nectar, but not with those of pollen. Finally, by comparing the polyphenolic profiles of honey, nectar and pollen sharing the same geographical origin, new data could be provided for a potential assessment of the botanical origin of buckwheat honey.
