In this study, the gold nanoparticles (AuNPs) were synthesized via redox reaction, by using ethylene diamine tetra-acetic acid (EDTA) as a protecting and reducing agent, with tetrachloroauric acid (HAuCl4) as precursor and seed solution. The ultraviolet-visible spectroscopy (UV-Vis) method was utilized to investigated the reaction conditions (the EDTA:HAuCl4 ratio, the amount of seed solution and stirring solution time) at room temperature. The synthesized AuNPs were deposited on the surface of fluorine doped tin oxide (FTO) by electrophoresis deposition.

Ebook "Wild-type food in health promotion and disease prevention: The columbus concept" to focus on the role of omega-6/3 polyunsaturated fatty acids in unhealthy diets. The volume is divided into five sections. The first identifies the missing essential ratio of competing essential fatty acids in the human diet and relates them to the upsurge of modern chronic disease and associated health costs. The authors also explain the scientific basis of the Columbus Concept and the evidence supporting the rehabilitation of dietary/blood cholesterol.

Small extracellular vesicles (sEVs) have great potential as new biomarkers in liquid biopsy. However, due to the limitations of sEVs extraction and component analysis procedures, further clinical applications of sEVs are hampered. Carcinoembryonic antigen (CEA) is a commonly used broad-spectrum tumor marker that is strongly expressed in a variety of malignancies.

Response surface methodology (RSM) was used to optimize ultrasonic-assisted extraction for total polyphenols from Artocarpus altilis based on single-factor experiment. The main factors, ultrasonic time, the liquid-solid ratio, the extraction temperature, the type of addition acid of single factor experiment was surveyed; the principle of design for 2 factors (extraction time and liquid-solid ratio) 2 levels response surface methodology was applied and the response surface optimization extraction conditions were studied.

The objective of the study was to determine the effect of increasing the ratio of SID TSAA to Lys in broiler chicks diets for 1 to 14 d of age on growth performance, efficiency of Lys utilization, caloric efficiency and carcass characteristics. In this study, 400 day-old straight-run Ross 308 broiler chicks sourced from a commercial hatchery were randomly allotted into 5 treatments following a Randomized Complete Block Design (RCBD).

In this work, the influences of boric acid and high alumina cement used as modifying additives on the formation of CaO∙Al2O3 and CaO∙2Al2O3 were studied. Herein, commercially available chalk of the M-90 label and technical alumina of the G-0 label were utilized as initial raw materials. Heat treatment of powder mixtures with various concentrations of modifying additives was carried out in the temperature range of 1250-1350oC with an isothermal exposure times of 1h and 2h.

In this study, CNC was isolated from used office papers by means of acid hydrolysis. For CNC/PEO fiber fabrication process, CNC was added to PEO aqueous solution to produce CNC/PEO fibers by electrospinning. In this process, several parameters were investigated, namely PEO concentration, CNC:PEO ratio, the applied voltage, and the distance between the tip and the collector on the morphology of electrospun CNC/PEO fibers.

In this study, ternary mixed oxide catalysts containing Al2O3-MoO3-MgO and Al2O3-MoO3-WO3 were prepared with a changing ratio of MoO3:Al2O3 between 0.05 and 20.00. All catalysts showed 100% selectivity towards propene during the conversion of propan-2-ol at temperatures between 220 and 400 °C. The catalysts prepared from WO3 possessed very strong acid sites, which cause higher catalytic activity than catalysts prepared from MgO.

In this work, 19 newly introduced and some traditional apricot cultivars were evaluated by 20 phenological and agronomical traits and fruit quality attributes. The results showed a wide variation in phenological data, tree vigour (TCSA), productivity [yield per tree, cumulative yield (CY) and yield efficiency (YE)], and fruit quality attributes such as fruit and stone weight, flesh/stone ratio, fruit dimensions, size, shape index, soluble solids content (SSC), titratable acidity (TA) and ripening index (RI).

Chitooligosaccharides (COS) have garnered great attention in the field of human healthcare. The prebiotic activities and antiglycation of COS were investigated using a combination of in vitro and in vivo studies. COS supplementation dramatically increased the levels of acetic acid, while reducing the concentrations of propionic and butyric acids.

Hydrogels based on biopolymers like Gum Arabic (GA) usually show low applicability due to weak mechanical properties. To overcome this issue, (nano)fillers are utilized as reinforcing agents. Here, GA hydrogels were reinforced by chitin nanowhiskers (CtNWs, aspect ratio of 14) isolated from the biopolymer chitin through acid hydrolysis.
