AB  - Recovering the bioactive components from pomegranate peel (PP) in the fruit-processing industry has attracted great attention in terms of minimizing the waste burden, as well as providing a new source of a multitude of functional compounds. The present study aimed to develop a feasible microencapsulation process of PP extract by using pectin and a pectin/2-hydroxypropyl-β-cyclodextrin (HP-β-CD) blend as coating materials. Microsized powders obtained by a spray drying technique were examined in terms of technological characteristics, exhibiting high powder yield and desirable moisture content, flowability, and cohesive properties. Assuming that the interactions with the used biopolymers occur on the surface hydrophobic domain, their presence significantly improved the thermal stability of the microencapsulated powders up to 200 °C. The health-promoting effects of PP have been associated with its high content in ellagitannins, particularly punicalagin. The obtained PP powders exhibited strong antioxidant and hypoglycemic potential, while an antimicrobial assay revealed their potent activity against Gram-positive bacteria. Additionally, an in vitro release study suggested that the used biopolymers can modify the release of target bioactive compounds, thus establishing a basis for developing an oral-controlled release system. Altogether, biowaste valorization from PP by the production of effective multifunctional microsized powders represents a sustainable way to obtain novel nutraceuticals and/or pharmaceuticals.

AB  - Regenerative medicine (RM) exploits the innate potential of the human body to effectively repair and regenerate damaged tissues and organs with the help of various biomaterials. Tissue engineering (TE) makes it possible to replace damaged tissues and organs with new ones. Research in the field of biomaterials has significantly improved the area of RM and TE. Biomaterials are used as orthopedic, dental, cardiovascular implants, medical devices, in the fields of reconstructive and regenerative medicine, among others. Important preconditions for the biomaterial to be used for implantation are its biocompatibility and biofunctionality. Biomaterials should enable adhesion, migration, proliferation and differentiation of cells. The biological properties of biomaterials are a reflection of their physicochemical properties, such as internal architecture, surface characteristics and charge. Biomaterials used in tissue regeneration should mimic the natural structure of the extracellular matrix and represent a physiological microenvironment for normal cellular functions. These biomaterials should also have adequate biodegradability properties to facilitate the formation and growth of new tissue. Biomaterials for use in RM can be of natural or synthetic origin, polymers by structural properties, ceramic and composite type, and based on bioreactivity they can be bioinert or bioactive. In RM and TE, polymers of different classes, natural and synthetic, are used, which can be made as intelligent materials. The structure of hydrogels in the form of a porous network represents a good matrix for cell activity. Ceramic biomaterials based on hydroxyapatite (HAp) are selected for use in RM and TE, especially solid tissues. Properties, such as composition, particle size, material shape, porosity, surface charge, topography, etc., are relevant for the proper use of HAp materials. The properties of HAp allow modification of its structure, surface, particle size design at the micro and nano level, hybridization with polymers, metals, etc. which is very important for its applications. Designed micro-nanohybrid HAp structure is most similar to the bone structure, making the cell environment closest to natural. Bone tissue engineering (BTE) is based on the combined use of cells, osteostimulating (osteoinductive) factors and biomaterials as a scaffolds and carriers for bone regeneration and defects repair. In BTE adipose-derived mesenchymal stem cells (ADSCs) are often used that are induced in vitro towards osteogenic cells or endothelial cells, and freshly isolated stromal vascular fraction can also be used. Blood components (PRP, blood plasma or blood clot) can be included in the composition of the BTE construct as a source of osteoinductive factors. In vitro models and methods were used to examine the biocompatibility, immunomodulatory and regenerative potential of biomaterials, as well as their influence on cellular functions. After in vitro methods, and before clinical studies, various in vivo animal models are used to examine the regenerative potential of biomaterials, such as subcutaneous implantations and bone defects in tibia, femur and calvaria in experimental animals (mouse, rat, rabbit).

AB  - The aim of the research was to develop microencapsulated powders of bilberry and chokeberry extracts via the spray drying technique. Two biopolymers, pectin alone and in combination with HP-β-CD, were used to preserve the antioxidant, hypoglycemic, photoprotective, and antimicrobial bioactivity of the berry leaf extracts. Moreover, the formed powders were characterized in terms of technological, chemical, and several biological properties. The obtained micro-sized powders (mean average particle diameter from 3.83 to 5.94 µm) demonstrated a process yield of up to 73%. The added biopolymers improved the flowability and cohesive properties of the powders and increased their thermal stability to 170 °C. The total content of polyphenolics in the powders ranged from 323.35 to 367.76 mg GAE/g DW for bilberry and from 186.85 to 227.59 mg GAE/g DW for chokeberry powders; meanwhile, chlorogenic acid was the predominant compound in powders. All samples showed stronger α-glucosidase inhibitory activity (IC50 values ranged from 5.00 to 19.59 µg/mL) compared with the reference standard. The study confirmed that spray drying is a suitable method for the preservation of the polyphenolic-rich extracts, while the addition of carriers has a positive effect on the improvement of microencapsulated powders’ properties.

AB  - An anthocyanin-rich blue maize waste product was used for anthocyanin extraction. To preserve bioactive phenolic compounds, a spray-drying technique was employed using conventional wall material maltodextrin (MD), with novel one, hydroxypropyl-β-cyclodextrin (HPBCD). The obtained spray-dried maize extract (SME) and microencapsulates were analyzed based on physicochemical powder properties, chemical analysis, antioxidant activity, and digestibility. The examined microencapsulates demonstrated good powder properties, exhibited a high powder yield (up to 83%), and had a low moisture content (less than 5%). HPBCD and MD + HPBCD combinations demonstrated superior powder properties in the terms of decreasing the time necessary for rehydration (133.25 and 153.8 s, respectively). The mean average particle diameter ranged from 4.72 to 21.33 µm. DSC analyses signified high powder thermal stability, around 200 °C, related to the increasing preservation with biopolymer addition. The total phenolic and anthocyanin compounds ranged from 30,622 to 32,211 mg CE/kg (CE—catechin equivalents) and from 9642 to 12,182 mg CGE/kg (CGE—cyanidin 3-glucoside equivalents), respectively, associated with good bioactive compound protection. Microencapsulates with both carriers (15% MD and 15% HPBCD) had the highest digestibility (73.63%). Our results indicated that the microencapsulates created with the active ingredient and the wall materials (MD and HPBCD) could protect phenolic compounds/anthocyanins against ABTS radicals (63.53 and 62.47 mmol Trolox Eq/kg, respectively).

abstract = "An anthocyanin-rich blue maize waste product was used for anthocyanin extraction. To preserve bioactive phenolic compounds, a spray-drying technique was employed using conventional wall material maltodextrin (MD), with novel one, hydroxypropyl-β-cyclodextrin (HPBCD). The obtained spray-dried maize extract (SME) and microencapsulates were analyzed based on physicochemical powder properties, chemical analysis, antioxidant activity, and digestibility. The examined microencapsulates demonstrated good powder properties, exhibited a high powder yield (up to 83%), and had a low moisture content (less than 5%). HPBCD and MD + HPBCD combinations demonstrated superior powder properties in the terms of decreasing the time necessary for rehydration (133.25 and 153.8 s, respectively). The mean average particle diameter ranged from 4.72 to 21.33 µm. DSC analyses signified high powder thermal stability, around 200 °C, related to the increasing preservation with biopolymer addition. The total phenolic and anthocyanin compounds ranged from 30,622 to 32,211 mg CE/kg (CE—catechin equivalents) and from 9642 to 12,182 mg CGE/kg (CGE—cyanidin 3-glucoside equivalents), respectively, associated with good bioactive compound protection. Microencapsulates with both carriers (15% MD and 15% HPBCD) had the highest digestibility (73.63%). Our results indicated that the microencapsulates created with the active ingredient and the wall materials (MD and HPBCD) could protect phenolic compounds/anthocyanins against ABTS radicals (63.53 and 62.47 mmol Trolox Eq/kg, respectively).",

AB  - Today's approach to tissue repair and regeneration often involves application of different biomaterials, alone or in combination with cells and/or growth factors. All materials, regardless of whether they are of natural origin or synthesized, cause a reaction in the surrounding tissue after implantation. This reaction involves a series of related events on which ultimately depends whether the implanted material will be well accepted and perform its primary role. Each material represents a foreign body for the organism and initiates a transient inflammatory reaction, the duration and intensity of which largely determine materil's further fate. Inflammatory reaction is influenced by material's chemical composition, the size and shape of its granules, porosity, compactness, as well as the degree of material's biodegradability. Thus, the fate of the material can go one of two ways: towards good integration with the surrounding tissue, supporting the cells with which it interacts and, in the case of biodegradable materials, replacement by healthy, functional tissue, or it will cause a strong inflammatory response resulting in the complete isolation of the material from the rest of the tissue with thick fibrous capsule. In vivo research of tissue response to implanted biomaterial involves investigation in different animal models and in different tissues, with orthotopic or ectopic implantations. We used orthotopic models for bone formation in rats and rabbits and models of subcutaneous implantation of various biomaterials in mice and rats. Numerous methods were used for the analysis of implants and surrounding tissue in the time periods of early and late response, such as histological staining, histomorphometry, immunohistochemistry, SEM, radiographic methods, analysis of specific gene expression and others. In vivo animal models for the purpose of preclinical studies are important in order to obtain guidelines for clinical application.

AB  - Nanomaterials are nowadays widely used in various fields of biomedicine. Before the application of biomaterials they have to be tested and fulfill some criteria. The first tests that should be performed after synthesis of some new nanomaterial with potential application in biomedical fields are biocompatibility tests. The aim of this study was to examine the influence of nanomaterial calcium phosphate/poly-(dl-lactide-co-glycolide) (CP/PLGA) on proliferation and adherence of HeLa cells in culture. For both proliferation and adherence examination, cells were treated with suspension of nanomaterial CP/PLGA at concentrations 5, 50 and 500 µg/mL, made in cell culture medium. There were four different types of treatment: (1) cells incubated with CP/PLGA for 3 days; (2) cells incubated with CP/PLGA for 6 days; (3) cells incubated first with CP/PLGA for 3 days and then for the next 3 days with medium and (4) cells incubated first with medium for 3 days and then for the next 3 days with CP/PLGA. Three days after incubation of HeLa cells with different concentrations of CP/PLGA nanoparticles’ suspension, the concentration of 5 µg/mL had mild inhibitory effect on proliferation. Increasing CP/PLGA concentration, there was stimulatory effect on cells’ proliferation. With prolonged incubation period, this dose dependence is lost. The highest adherence of HeLa cells was observed when cells were incubated with the highest examined concentration of CP/PLGA suspension, in both 3-day and 6-day incubation period. Based on the results obtained in our study, we can conclude that the effect of the suspension of nanomaterial CP/PLGA on proliferation and adherence of HeLa cells depends on the duration of incubation with the cells as well as the material concentration and type of the treatment.

AB  - The aim of this study was to investigate the osteogenic potential of freshly isolated adipose tissue-derived mesenchymal stromal/stem cells (ASCs) in bone regeneration of rabbit calvaria defects. ASCs were applied together with calcium phosphate-poly-DL-lactide-co-glycolide (CPPLGA) nanoparticles that are mixed in an appropriately prepared blood clot (BC). Parallelly were analysed defects filled with fragmented adipose tissue (FAT) instead of ASCs, with CP-PLGA in BC, and only with nanoparticles. Bone density in defects was measured after I, III and VI weeks, and histological examination was done after IV and VIII weeks after filling defects. Approach to assisted osteoregeneration which is based on the use of fresh non-induced ASCs has proven to be promising due to the favorable effect on bone regeneration and simplicity of their application.

AB  - Simulated body fluid (SBF) is an artificial fluid which has ionic composition and ionic concentration similar to human blood plasma. Purpose: This paper compares the interaction between the nanomaterial containing calcium phosphate/poly-dl-lactide-co-glycolide (N-CP/PLGA) and SBF, in order to investigate whether and to what extent inorganic ionic composition of human blood plasma leads to the aforementioned changes in the material. Methods: N-CP/PLGA was incubated for 1, 2, 3, and 5 weeks in SBF. The surface of the material was analyzed on SEM-EDS and FTIR spectrometer, while SBF was subjected to pH and electrical conductivity measurement. Results: Our results indicate that dissolution of the polymer component of the material N-CP/PLGA and precipitation of the material similar to hydroxyapatite on its surface are based on the morphologic changes seen in this material. Conclusions: The mechanism of the apatite formation on the bioceramic surface was intensively studied and was considered crucial in designing the new biomaterials. The results obtained in this work indicate that N-CP/PLGA may be a good candidate for application to bone regeneration.

abstract = "Simulated body fluid (SBF) is an artificial fluid which has ionic composition and ionic concentration similar to human blood plasma. Purpose: This paper compares the interaction between the nanomaterial containing calcium phosphate/poly-dl-lactide-co-glycolide (N-CP/PLGA) and SBF, in order to investigate whether and to what extent inorganic ionic composition of human blood plasma leads to the aforementioned changes in the material. Methods: N-CP/PLGA was incubated for 1, 2, 3, and 5 weeks in SBF. The surface of the material was analyzed on SEM-EDS and FTIR spectrometer, while SBF was subjected to pH and electrical conductivity measurement. Results: Our results indicate that dissolution of the polymer component of the material N-CP/PLGA and precipitation of the material similar to hydroxyapatite on its surface are based on the morphologic changes seen in this material. Conclusions: The mechanism of the apatite formation on the bioceramic surface was intensively studied and was considered crucial in designing the new biomaterials. The results obtained in this work indicate that N-CP/PLGA may be a good candidate for application to bone regeneration.",

AB  - The purpose of biomaterials is to replace a part or a function of the body in a safe, physiologically and economically acceptable way. The process of the reconstruction of bone defects has always been a big problem in orthopedics and maxillofacial surgery. Since hydroxyapatite (HAp) was detected as a component, the predominant constituent and the integral element of Mammalian bones, the development of the phospate ceramics as potential materials for implantation was enabled. This study investigated whether and in which way biomaterial calcium hydroxyapatite/poly-L-lactide (HAp/PLLA) interacts with the ionic composition of the human plasma. The simulated body fluid (SBF) is an artificial fluid that has the ionic composition and ionic concentration similar to the human blood plasma. HAp/PLLA was incubated for 1, 2, 3 and 5 weeks in SBF. The surfaces of both treated and untreated materials were analyzed on a scanning electron microscopy (SEM), and were also exposed to the energy dispersive X-ray spectroscopy (EDS), while SBF was submitted to the measuring of pH and electrical conductivity. However, our results indicate that the degradational changes of the material HAp/PLLA in SBF start from the surface of the treated material and that observed changes are the consequence of dissolution of its polymer component and the precipitation of the material similar to hydroxyapatite on its surface. This material shows good characteristics that place it among good candidates for the application in orthopedics and maxillofacial surgery.
