“…Those products are essential for a balanced healthy died and are highly requested by consumers [14]. Berry species are more and more requested for their richness in vitamins, minerals, amino acids, active principles, especially anti oxidants [15], being considered functional food [16]. "Super Fruits" as blackberry, raspberry, blueberry [17], black and red currant [12], sea buckthorn (Hippophae rhamnoides), chokeberry (Aronia melanocarpa), honeysuckle (Lonicera caerulea), wolfberry/Go Ji (Lycium barbarum) are produced in temperate zones for fresh consumption and processing, their cultivation being possible with high efficiency in small family farms and urban areas [6].…”

Fruit production in Europe has a dual system organization: an industrial type with high density planting systems in large extension farms and a small size orchard type in family owned farms. Certainly, the two systems are quite different in terms of fruit varieties, planting systems, orchard management and fruit production valorisation.In recent years, the smart family fruit farms became more and more important for the rural economy by increasing the efficient use of local resources, by offering social security and comfort and by reducing the environmental fruit finger print.Besides the already existing orchards, new ones are planted with trees produced using local species and varieties, better adapted to soil and climate conditions, grafted on resistant rootstocks. Low input orchard technologies, organic fertilization and integrated pest management are generally used. Natural windbreaks and shelters, grass soil cover management are generalized in order to ensure a higher biodiversity and the protection of wild life. Local fruits are produced in many cases under registered Protected Designation of Origin (PDO), Protected Geographical Indication (PGI), and Traditional Specialties Guaranteed (TSG). Those insure the product authenticity, a quality control system and a better marketing. Fruits are sold fresh on the local markets and in modern distribution network but also processed in the farm or in cooperative processing units. Special products are obtained following traditional recipes, some of the being sugar free, rich in vitamins, active principles and considered functional food.Continuous science and technology development brings innovation also in orchard technologies in European small fruit farms aiming to maintain their sustainability and competitiveness, by producing top quality fruits, with nearly to zero residues and no environmental negative impact. The European model of small smart fruit farms could be introduced and tested to Indonesian condition.

Silver nanoparticles (AgNPs) have been synthesized in the presence of Strawberry fruit extract (SBFE) at room temperature. The synthesized AgNPs was characterized by UV-vis spectroscopy, SEM, EDS, XRD, TEM and FTIR. The UV-vis spectra of the AgNPs show SPR band at 450 nm. TEM results indicate that AgNPs are spherical in shape and size range between 7-65 nm. Antibacterial activity of the synthesized AgNPs has been assessed against Pseudomonas aeruginosa and Bacillus licheniformis. The results show that AgNPs exhibit inhibitory effect and effect is a function of AgNPs concentration. The antibacterial activity of the prepared AgNPs has been compared with two antibiotics, amoxicillin and ciprofl oxacin. It is found that the antibiotics perform better than AgNPs.

“…The phenolic compounds are composed of one or more aromatic rings with varying degrees of hydroxylation, methoxylation and glycosylation, and various studies have associated the structure of phenolic compounds with their antioxidant properties [102,104]. The antioxidant activity generally increases with the degree of hydroxylation in aromatic rings and decreases with C-3 methoxylation [105,106].…”

Novel Prospects in Oxidative and Nitrosative Stress

The imbalance between reactive oxygen species (ROS) production and antioxidant defenses determines the condition called oxidative stress. When there is an increase in ROS production or a decrease in the antioxidant defenses, this systemic antioxidant/pro-oxidant imbalance may lead to the accumulation of oxidative damage, which, in turn, may lead to a modification of biomolecules. These consist of reactions resulting in protein adducts, DNA oxidation, and formation of lipid peroxides, which, in turn, reduce the cellular functional capacity and increase the risk of disease development. The body has natural scavenging systems against free radicals and other reactive species. However, sometimes the endogenous antioxidant capacity is exceeded by the production of ROS. When this occurs, exogenous antioxidants exert important function for the human health. These bioactive compounds act preventing and neutralizing the formation of new reactive species and free radical s .I ns o m ec a s e s ,a n increase of ROS can help the host to resolve an infection or even to control the tumor growth. Finally, the levels of ROS can be perceived by signal transduction pathways involving known targets(i.e.,p53,Ras,andNF-κB) and regulate physiopathological events such as the cellular cycle, apoptosis, and inflammation.Keywords: reactive species, cellular oxidation, antioxidant system, health, disease © 2018 The Author(s).

Cellular respiration and generation of reactive species in the mitochondria: implications in cell viability and agingOxidative phosphorylation is the center of energy metabolism in plants, animals and several microbial life forms [1]. In eukaryotes, this process occurs in mitochondria. The mitochondria is a cytoplasmic organelle surrounded by two membranes, outer and inner membrane, which main function is the production of most of the phosphate compounds necessary for the energetic balance of the cell. In addition, other functions such as the regulation of the body'sheatgeneration [2][3][4] programmed cell death [5][6][7], reactive oxygen species (ROS) generation and cell signaling [8] is also associated with mitochondria. Cellular vitality is directly related to mitochondria, and mitochondrial dysfunctions are frequent causes of accidental cell death [5,[9][10][11], cancer [12, 13], diabetes [14][15][16] and neurodegenerative diseases [17][18][19], among others.The characterization of the respiratory electron chain could be performed in studies using the fractionation of its components by certain detergents that at low concentrations break the interactions between proteins and lipids in the membranes, leaving associations between proteins intact [20]. In electron transport chain, through this process, four protein complexes were found....
