In last decade, Romanian agriculture does not follow entirely the European and programs as concerns land exploitation and animal farming (SAPARD). Restrictive development projects (POS-MEDIU, POS-DRU, POS-CCE) were active only in large private farms, which represent only 10.7% of the total registered farms in Romania. Was used a questionnaire for 36 students of our faculty, which have animal farms in 7 counties in Northwest of Transylvania. The study want to put into evidence the current problems of farmers in conditions of some private farms with small and middle number of animals. As small farms, they do not obtain important productions because of financial resource absence, limited professional education and absence of association in bigger exploitation farms. In these situations, the government must react providing a legal frame for rural agricultural development, supporting and supervising these small exploitations.

This paper analyzes the management and administration of one of the largest, beautiful and complex natural parks from Romania, the Iron Gates Natural Park. The management plan is a frame of integration of the biodiversity conservation problems and protection of the natural and cultural environment that also supports socio-economic development of Iron Gates Natural Park. It is also an instrument of dialog between the institutions which coordinate this area. The management plan is a document approved by H.G 1048/2013 and it resulted after consulting the interested factors of the area (city halls, local and central authorities, civil society). The administration of Iron Gates Natural Park has a new structure, founded in 2003 and is working as a subunit of Forest-National Administration (Romsilva), which assures the necessary personal and equipment for administrating the area. The area has the status of: Natural Park, Natura 2000 and Ramsar site. The forest represents 65% of the total area, 98% being a state property. Analysing Iron Gates Natural Park documents (Iron Gates Natural Park management plan, scientific council and park administration documents, visits and observations within park), we can conclude that the park has a good administration leaded by the scientific councils, who also achieved many successful European projects.

Papers on beta- glucuronidase sensitivity and specificity for identifying Escherichia coli in sources of environment, food, water, etc. have been published since 1976. In this study we conducted a review of the incidence of E. coli I² - glucuronidase -positive in goat milk, obtained by hand milking throughout the lactation: spring, summer, autumn. The presence of E. coli in milk is considered both as a health indicator and a pathogenic factor capable of causing food poisoning. The determination of the E. coli I²-glucuronidase-positive was carried using TBX medium by cultivating colonies typical blue at 44 0 C. The absence of E. coli in milk yielded during the spring, when the animal milking is done three times a day, was found in the performed analyses; the same was observed during fall, when the milk production is lower and the milking is done once a day. The load of E. coli I²-glucuronidase-positive was averaging 66.67 CFU/ml of goat milk, during the middle lactation period (July-August), in conditions of higher temperature. During this period, milking is done in the mountain zone, where the transhumance of animals takes place in summer. The presence of the species E. coli was also confirmed by microscopic examination. Attention should be paid to hygiene and milk should be immediately cooled, during hot weather, as E. coli can be a source of food poisoning. Â

The plant kingdom is an inexhaustible source of bioactive compounds with antioxidant character. It is known that, natural polyphenols are essential compounds in stimulating plant growth and development. The aim of this study was to identify the internal structure changes in maize ( Zea mays L.) seedlings, under the influence of hemp shives polyphenolic extract. Hemp shives polyphenolic extract was characterized in terms of the total content of polyphenols and individual content by HPLC. Germination tests were carried out going through a standard procedure. In order to perform the histo-anatomical characterization, the vegetal material was fixed and preserved in alcohol 70%, following to be cut by hand microtome. The sections obtained were stained using double staining reagents: green - iodine and ruthenium red. It was observed, compared with the control, that hemp shives polyphenolic extract determines a good development of the root hairs and increase leading bundles number and central vessels metaxylem. Hemp shives polyphenolic extract in lower concentrations has positive effects on developed process of Zea mays L. plants that can be attributed to bioregulation properties.

Introduction: Presently, the scientists recognize the health benefits of food fibers in the menu and also plant food sources are at high interest both for general population and food companies. The food companies are responsible for a clear nutrition labelling that will assist consumers to make informed and healthy choices and health providers has to inform the population about the benefits of fibers. The aim of our study was to evaluate the Romanian knowledge and attitudes regarding dietary fibers from food products. Materials and methods: We made a qualitative survey based on a questionnaire applied in 2015, over a period of 6 months, over 670 Romanian consumers. It was focused on testing the attitudes and knowledge towards ingestion of foods rich in fibers. For all data analysis we used the software SPSS, from IBM Inc. Results and Discussions: Our results showed that the knowledge about dietary fibers and also the ingestion of food products rich in fibers were low, and most of the subjects didn’t have any interest to read the nutritional information from food labels related to fibers. The female participants ate more whole grains and fruits than males and pay more attention to food labelling, the Romanian people prefer to stay and eat home than at restaurants especially in rural areas, and the knowledge about fibers benefits was significantly related to education and urban location. Conclusion: We underline the needs for more efficient community interventions and proper information about the importance of dietary fibers for our health and also to improve and disseminate our nutritional standards and diet recommendation among population.

Astaxanthin is a marine carotenoid that has a number of potential health benefits, including a very strong antioxidant potential. Present in the flesh of salmonids and shellfish, its natural sources currently on the market for food supplements come from the algae Haematococcus pluvialis and krill. However other natural sources can be found and may be of interest. Cellular uptake studies were performed on Caco-2/TC7 colonic cells. The cells were cultured on a semi-permeable membrane to create a polarized and functional epithelium, representative of the intestinal barrier. Four sources of astaxanthin were selected and compared; synthetic, natural extracts from bacteria, algae or yeast. Astaxanthin was incorporated at a concentration of 5µM into mixed micelles and applied to cultured cells and concentration of astaxanthin measured by HPLC in both apical and basolateral compartments. Small variations in bioavailability were observed at 3 hours. After 6 hours, only the algae source of astaxanthin was still present in the apical compartment as the esterified form. Structure-activity relationships are further discussed. Animal experiments using yeast and algae sources in different types of matrices confirm the role of source and formulation in the bioavailability potential of astaxanthin.

The juice from wheat grass is called "green blood" and is an excellent detoxifying, facilitating the elimination of toxins and fats from body. In the form of fresh juice, it has high concentrations of chlorophyll, active enzymes, vitamins and other nutrients. The aim of this work was the development and characterization of a functional beverage from green wheat juice by adding apple and limes. The antioxidant capacity, vitamin C, polyphenols and flavonoids content were quantified by using spectrophotometry. The final product was pasteurized and evaluated by the content of bioactive compounds during storage at intervals of 7 and 14 days. During storage there were found slight decreases of the contents of bioactive compounds. The juice obtained has a sweet-sour taste, a unique flavor and a very pleasant smell. This product targets all categories of consumers and represents an ideal morning snack for those who are concerned about a healthy lifestyle.

Plasmonic nanoparticles can be used as building blocks for the design of multifunctional systems based on polymeric capsules. The use of functionalised particles in therapeutics and imaging and understanding their effect on the cell functions are among the current challenges in nanobiotechnology and nanomedicine. The aim of the study was to manufacture and characterize polymeric microstructures by encapsulating plasmonic gold nanoparticles in biocompatible matrix of sodium alginate. The gold nanoparticles were obtained by reduction of tetracluoroauric acid with sodium citrate. To characterize the microcapsules, UV-Vis and FTIR spectroscopy, optical and confocal microscopy experiments were performed. In vitro cytotoxicity tests on HFL-1 cells were also performed. The capsules have spherical shape and 120 I¼m diameter. The presence of encapsulated gold nanoparticles is also shown by confocal microscopy. In vitro tests show that the microcapsules are not cytotoxic upon 24 h of cells exposure to microcapsules concentrations ranging from 2.5 to 25 capsules per cell. The obtained microcapsules of sodium alginate loaded with plasmonic gold nanoparticles could potentially be considered as release systems for biologically relevant molecules.

The use of functionalised particles in therapeutics and imaging and understanding their effect on the cell functions are among the current challenges in nanobiotechnology and nanomedicine. The aim of the study was to manufacture and characterize polymeric microstructures by encapsulating plasmonic gold nanoparticles in biocompatible matrix of sodium alginate. The gold nanoparticles were obtained by reduction of tetracluoroauric acid with sodium citrate.
