The misuse and abuse of antibiotics and synthetic drugs has led to increased resistance of pathogens and therefore difficulties in treating these medical conditions, requiring the development of new materials with antimicrobial efficacy. Thus, the aim of the study was to determine the therapeutic potential of hydrogels based on plant extracts (Chelidonium majus L., Arnica montana L., Calendula officinalis L., Aristolochia clematitis L., Hippophae rhamnoides L.) and zinc oxide nanoparticles in skin lesions by assessing cytotoxicity and cell viability. The two types of zinc oxide nanoparticles were obtained at 100 atmospheres and oven dried as well as at 100 atmospheres and spray dried. The data from our study suggest that none of the hydrogels tested show a notable cytotoxic effect on fibroblast culture. Dilution of the stock product in all experimental samples resulted in a cell viability of over 80%, reflecting that these hydrogels may be a therapeutic alternative in the wound healing process.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129359351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analyses were made to determine pH, CaCO3, EC, organic matter, available phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn) and copper (Cu) in soil samples and nitrogen (N), P, K, Ca, Mg, Fe, Zn, Mn, Cu, and boron (B) in leaf samples. In the study, the relationships between some physical and chemical properties of the soils and the plant nutrient content of the leaves were evaluated by correlation analysis. In the study, between some physical and chemical properties of soils and the nutritional elements of soils and leaves were found important statistical relations. These relationships were mostly between soil samples rather than leaves. On the other hand, the pH and EC values of the soils showed less significant relationships with the nutrient contents of the samples according to the organic matter and CaCO3 contents of soils. It was determined that the organic matter content of the soils had a positive relationship with all the investigated elements except phosphorus. It has been determined that the relationship between the CaCO3 content and nutritional elements in the soils is statistically significant, it has a positive correlation with potassium and calcium and a negative correlation with other investigated elements. No significant relationships were found between the nutrient contents of the soils and the macro element contents of the leaves. While some important statistical relationships were determined between nutrient contents of the soils and micro element contents of the leaves, the highest correlation was determined between copper and boron contents. It was determined that the copper content of the leaves was positively related to the phosphorus, potassium and magnesium content of the soils and negatively related to the manganese content of the soils.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120979538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These included following the phenological stages (flowering period and fruit ripening period), but also the particularities of the fruit in terms of physical characteristics and biochemical composition. The highest weight of the fruit was recorded in 2020 in the ‘Regina’ cultivar. ‘Regina’ is characterized by an average flowering period, lasting between April 11th and 28th. The earliest cultivar both in terms of flowering and fruit ripening is the ‘Golia’ cultivar. All other varieties have an average fruit ripening period (June 15th-30th).

The system was placed in a micro-greenhouse made of polyethylene foil, according to a plan for the location of technological equipment, by reconditioning and arranging tunnels for growing of grafted plants. The construction included tunnels with a length of 7.40 m and a width of 1.81 m (fish growth tunnel, 70 cm high, made of 20 mm thick OSB boards, mesh and durable foil, 8 rectangular basins, with holes for aeration, water supply and drainage and inside two layers of ultra-additive foil, 0.2 mm thick and and tunnels for growing plant material), reconditioned by mounting a protective foil, attached in PVC clips to the skeleton of the tunnel and the base of the pools with an inclined slope of 5-10% for draining water and residues), installations, pumps, filters. It has been tested for growing carp (Cyprinus carpio) and lettuce (Lactuca sativa).
