Optimization offermentation parameters for vegetable juices with nitrate content to obtain natural nitrites

The aim of this study was to obtain a nitrites-containing juice by fermentation of plant materials that contain nitrates, and finding the best parameters of fermentation to obtain the highest concentration of nitrite. Celery and parsnip vegetable juices were obtained by manually pressing of chopped material plants. Staphylococcus carnosus and Staphylococcus xylosus used for vegetable juice fermentations were isolated and then identified from a starter culture. The nitrate and nitrite concentration (ppm) was determined before and after 20 hours and 30 hours of fermentation at different concentration of NaCl (0, 5.0, 7.5, 10.0, wt. %), different temperatures (4°C, 35°C, 45°C) and different pH value (5.0, 6.0, 7.0) for each composition. For nitrates and nitrites determination, colorimetric methods were used. After 20 hours of incubation at 35°C, in the absence of NaCl and pH 7.0, it was obtained a concentration of 897.3±7.3 ppm nitrites in the presence of Staphylococcus xylosus, comparative with 799.3±6.7 ppm nitrites in the presence of Staphylococcus carnosus. The highest nitrate concentration was determined for raw parsnip juice, while nitrites were not detected in fresh vegetable juices of celery and parsnip. Fermentation formulas without added salt showed the highest concentration of nitrites, optimum temperature for juices fermentation was 35°C, and optimum pH value for juices fermentation was 7.0

Identification of abdominal cutaneous perforator artery in pig using the Angio-CT technique

Identification of vascularization of cutaneous skin flaps is an important step in reconstructive surgery, both in humans and veterinary medicine. Choosing the right cutaneous flap imply evaluation of its perforators vessels abundancy also reducing the morbidity of the donor and the receivers site. Cutaneous perforators represent a reliable source of vascularity allowing reconstruction of defects in plastic surgery base on the principle of reconstructive similarity. Materials and methods. The study was conducted on 5 pigs, PIC-F 11-337 hybrid, with a weight between 35-55kg. The pigs were subjected to sedation and anesthesia. The contrast agent used for Angio CT was VISIPAQUE 320 that was automatically injected using a CT 9000 ADV Contrast Delivery System. Scanning procedure was performed on SIEMENS SOMATOMSCOPE system. Results and discussions. After contrast agent injection, the scan was performed at 3 mm slice thickness, 110-130 kV and 25-66 mAs, and the reconstruction was made at 0.5 mm and 1 mm per slice. In the arterial time were identify the cutaneous perforators that irrigate the abdominal skin. Base on Angio CT images, the vessels identify with contrast agent were tried to by highlighted using surgical procedures. Conclusion. CT Angiography is a technique that help chart the cutaneous perforator, being an imaging technique that have a real potential in establishing the proper cutaneous flap in case of plastic surgery

Research and Science Today Journal is a publication founded in 2011 and it is dedicated to the students of all levels (license, master and doctoral) of faculties in the country and abroad. We want to offer the participants the opportunity to present their scientific works in the following areas: Social Sciences, Economic Sciences, Legal Sciences, Humanities, Education Sciences, Engineering, Medicine and Sport. This journal provides students the opportunity to create and / or to improve their abilities to write scientific papers. So each appearance (two appearances per year at which we can add supplements) contains a number of papers written by students, masters and doctoral from the faculties from the country or / and abroad. The journal promotes original studies contributing to the progress of knowledge and it is motivated by the need to address issues of theory and practice in the areas mentioned above. The Journal is a training means of the factors involved in the conceptualization, development, implementation and evaluation , aiming the formation of creative personalities who could be able to adapt through the changing conditions of life. Journal wants to be a forum for debates disciplinaries and interdisciplinaries theoretical topics, to become a research support, to leverage this work at regional, national and international levels. We believe that this gathering will enjoy the support from both parts of the researchers and of the practitioners, and will provide appropriate training sources held professional through the current problems
