Abstract For a long period of time, cryopreservation and dilution of sperm represented a very important role in improvement of biotechnology of artificial insemination in the bovine. Regarding to this fact the study has been realized in period 2016- 2017 at the center of amelioration for seminal material, Semtest-BVN Târgu-Mureș and at the laboratory of theriogenology of Faculty of veterinary medicine Bucharest. In this study, 7 ml sperm from one Holstein bull (SunnyBoy) was obtained using artificial vagina. The ejaculate was divided to 5 parts and diluted using Triladyl extender (250 g) adding vitamin E with 2 concentrations 1μmol or 2 μmol, catechin 0.1μmol, Trolox 0.1 μmol, and a standard probe without adding antioxidants. Straws had been analyzed using Computer- assisted sperm analysis (CASA) for motility and composite after thawing. As a first conclusion of this study, it can say that the group with vitamin E presented a higher motility than the other groups.

Abstract The aim of this paper was to present a histological evaluation of the treatment performed on a humanmodel of osteomyelitis induced in rabbits. Osteomyelitis was induced in rabbits by a human strain of Staphylococcus aureus injected in bone defects created in the rabbit tibia. There have been created five groups of animals, groups receiving treatment in two different stages of the disease, acute and chronic. Copper and silver sub-millimetre-particles were introduced in the same place with the Staphylococcus solution. Evaluation of installation and evolution of the disease was done by clinical, hematological, microbiological, radiological and histological monitoring. A separate study of histological data is presented here. Histological examinations performed by HE was done on 5 μm sections of uncalcified bone. Every examination was classified according to a system of score. The results of histopathological evaluation confirm that histological analysis is a powerful tool in experimental models of this disease.

Abstract Sex ratio, morphometric characteristics, age and growth for Pontic shad from Romanian Black Sea Coast were examined. A total of 2.133 individuals were caught between March 2012 and September 2013. Female : male sex ratio was 0.62. According to the age reading, distribution varied form II to V year. The von Bertalanffy equation and growth performance index were determined by ESP software in Pontic shad. The asymptotic length (L∞ = L infinity) of Pontic shad generated by the ELEFAN I method, after introducing total length data for the two years of study, was 41.5. The natural mortality instantaneous coefficient (M) of the entire Pontic shad population, calculated according to Pauly’s empirical equation, using the growth parameters of the Von Bertalanffy formula and the mean annual temperature of the two study years of 13°C, recorded the following values: M = 0.585 in 2012 and M = 0.639 in 2013. According with the resultants, it is recommended to perform a sustainable fishing which allows the capture of legal-sized of fish.

Abstract The decontamination and detoxification of pesticides-contaminated soils is a tough task, due to their persistence and mobility. Camelina sativa is resistant to pests and weeds which affect similar crops mostly due to its unique defence system, attributed tocamalexin and metoxi-camalexin. Considering this, camelina may be cultivated without input of pesticides, but what happens if camelina is cultivated on an already pesticide-contaminated soil? The purpose of the study is to analyze the Camelina sativa potential to concentrate or not the residual pesticides from the soil in its seeds.It was assessed the level of pesticides from the soil on which Camelina sativa-Mădălina variety was cultivated and from the resulted seeds. The quantification was done using a GC-MS-MS equipment. In the soil it was found a total amount of 0.03 mg/kg of pesticides consisting in: o,p-DDE, p,p-DDE, o,p-DDD, o,p-DDT, p,p-DDT, from which 81.4% was p,p-DDE. All the signals registered for camelina seeds were below the LOQ of 0.005mg/kg. Camelina sativa-Mădălina variety can be cultivated on soils contaminated with DDT and its metabolites, minimizing the risk of pesticides translocation.

Abstract Plant growth promoting rhizobacteria (PGPR) are of growing interest for their potential role in improving soil fertility and enhancing crops productivity and nutrients contents. In order to assess the impact of PGPR on nutrients contents of soybean, a greenhouse experiment was carried out with Bradyrhizobium japonicum applied alone or in combination with Pseudomonas putida in conjunction with fertilization of P or manure. Two soil moisture regimes were installed: 70% of whole holding capacity (WHC) as control and 35% WHC as moderate water stress. The water deficit was imposed at the flowering stage for 12 days. Plants cultivated under P insufficiency and drought exhibited lower physiological parameters in treatment with single inoculation of B. japonicum than combined application of two rhizobacteria. The results showed that the combined application of rhizobacteria enhanced the N and P contents of soybean regarding of soil water conditions. The integrated use of rhizobacteria improved the relative water content of soybean. Their influence was more pronounced under P deficiency and manure fertilization of plants especially under no stress water conditions. Hence, combined application of B. japonicum and P. putida has a potential to improve nutrition and growth of soybean under normal soil moisture as well as under moderate drought.

Abstract In the last years sunflower become one of the most important crops in Romania. The most of the surface cultivated with sunflower from our country is located in south and south-east and, in many cases, sunflower is cultivated after maize. As result the attack of the maize leaf weevil (Tanymecus dilaticollis Gyll) at sunflower plants has increasing. The attack is dangerous when sunflower plants are in first vegetation stages (BBCH 10-BBCH 14). Similar with maize crop, sunflower seeds treatment with neonicotinoids were generalized after 2007. As result of the EU directive 485/2013, no active ingredients remain available for sunflower seeds treatment, against T. dilaticollis, in Romania. The researches from the last years were orientated for finding of the possible alternatives for seed treatments, in eventuality of permanent ban of neonicotinoid insecticides, after 2018. Because of the variability of climatic conditions from the field, during spring period, researches concerning effectiveness testing of sunflower seed treatments, in green house conditions, using high pest pressure is a good method to evaluate influence of the different active ingredients to control T. dilaticollis adults. In this experiment it has tested three doses of cyantraniliprole active ingredient (7.5, 10.0 and 12.5 l/to) and three neonicothinoid active ingredients (imidacloprid, clothianidin, thiamethoxam). Sunflower seeds were placed in plastic pots. After plants emergence the insects were added in pots. At each pot it has added 20 adult insects, collected from the field. Each day, it has recorded insect mortality. At 8 days from the start of the experiment, it has assessed attack intensity of the adult insects on sunflower plants. The attack was evaluated using a scale from 1 (plant not attacked) to 9 (plant complete destroyed). In conditions of high pest pressure (4 insects/plant) the attack intensity of T. dilaticollis at sunflower plants was ranged from 3.35 in case of variant treated with clothianidin and 8.50 in case of untreated plants. Lower attack intensity of the pest at sunflower plants it has registered in case of variants treated with imidacloprid and thiamethoxam (I=3.58 and 3.50). Plants emerged from the untreated seeds were destroyed by the insects, at 8 days from the start of the experiment.

Abstract Fish meat consumption has gained a lot of popularity in Europe in the last years. It is considered to be a great alternative for red meat because it provides large amounts of Omega-3 fatty acids and vitamin D. These components lower the risk of cardiovascular disease, reduce the risk of autoimmune diseases, are essential for growth and development, can contribute to mood elevation and can prevent cognitive decline, and eye disease. Unfortunately the benefits can sometimes be accompanied by a risk associated with chemical and microbiological contaminants. The aim of this paper is to review some recently published studies concerning the groups of chemical compounds and bacteria found in fish meat, which can have negative effects on human health. In order to raise awareness, aspects related to dangerous persistent organic pollutants and zoonotic bacteria are described. The frequency of encountering them is discussed, the ways in which they can reach the human body are specified and a critical comparison of their consequences is performed.

Abstract Paulownia ssp., in its places of origin, has been cultivated for over 2600 years and used as protection curtains against sand storms or floods, studies of how this species was exploited only fifty years ago in time what genetic research has only been affected in the last thirty years. The fundamental purpose of experimentation was to check the influence of different technological links (planting density and fertilization scheme), not only on the weight of the wood and the technological characteristics of the wood obtained, but also on the total biomass accumulation. The objectives of the research were: a) stems diameter increase, measured at 100 cm height from the soil surface, maintaining the harvest variant at 4 years; b) increasing of biomass accumulation. In all experimental variants, it is noted that the plants recorded higher values of the different variables analyzed (diameter at the base, normal diameter and total height), when the fertilization factor also intervenes. In the same way, when a higher fertilization was applied, higher values of the dendrometric indicators are obtained compared to the experimental variants that did not benefit from the supplementation of nutrients, suggesting that the most important risk factor in Paulownia plantations is the planting density and the fertilization element.

Abstract Phosphorus (P) and Selenium (Se) supplementation to rice plants grown in Arsenic (As) contaminated conditions as be found by many studies to reduce As uptake and benefit growth in such conditions, however there are some inconsistencies as to how effective these treatments are. This study investigates the effect of 0, 0.5, 1, 1.5 and double the recommended concentration of P and Se on the growth of rice seedlings both with and without the presence of As over a maximum 20 day period. Analysis of the growth data collected indicated that there is no significant difference in the leaf, maximum and minimum root lengths, leaf and root numbers or the As content of the plant material. This study finds that different concentrations of P and Se do not affect growth at early stages and do not affect As uptake.

Abstract Comparing responses of the same soil under long-term different treatments is vital in determining the best management practices to conserve soil health and sustain productivity. This study was investigated to determine the effects of longterm (2006-2015) two conventional (CT), three reduced (RT) and a no-till (NT) treatment on bulk density (BD), field capacity (FC), wilting point (WP), available water content (AWC) and total porosity (TP) of a clayey soil in eastern Mediterranean region, Turkey. Undisturbed soil samples were collected from 0-10, 10-20 and 20-30 cm depths of experimental plots with a crop rotation of winter wheat (Triticum aestivum L.), soybean (Glycine max. L.), grain maize (Zea mays L.). The AWC under CT was higher than the RT and NT. The BD was increased with depth in all treatments, and was higher under RT and NT than the CT. The long-term experiment revealed that BD increase under long-term RT and NT should be monitored to avoid deterioration of soil health, and yield loss due to limiting root penetration and storing available water needed during drought periods.
