The identification of these properties allows recognize the potential use of this natural resource.

High vacuum steam distillation, simultaneous distillation extraction, steam distillation, purge and trap methods are used for sample preparation in volatile component analysis. Since these methods are difficult and costly to implement, these methods have left their place to the solid phase microextraction technique. Extraction conditions such as extraction temperature, extraction time, sample volume and fiber type should be optimized in order to increase the efficiency of extraction in volatile component analysis with solid phase microextraction in foods. In the optimization of extraction conditions in volatile component analysis of foods, studies have been carried out to utilize the response surface method, which reduces the number of experiments and also examines the interaction effect of the independent variables. In this review, it is aimed to give information about current studies using response surface methodology in optimization of volatile compound analysis of foods using solid phase microextraction technique.

This study assessed seasonal incidence, economic losses, the efficacy of therapeutic protocols, the recovery time of affected animals and specific prophylactic measures applied to sheep with acute infectious pododermatitis. The studies were conducted over a period of 12 months in 3 different sheep farms from private units in the same area. The results of the study showed an increased incidence of the disease in all 3 farms, with an average of 26.94% of the sheep flock. The incidence of the disease was increased in the months of April-May-June-July and September-October (30%), when there were heavy rains. The high morbidity led to economic losses through the decrease in milk production by approximately 30% and the decrease in the weight of the sheep by 10.58% (4.2 kg) of their normal weight. The therapeutic protocol applied locally as well as parenterally, combined with a foot bath with 10% zinc sulphate solution, were effective in treating acute infectious pododermatitis of sheep. The average recovery time (days) was approximately the same in the three groups of sheep (5.25 ± 0.68 days for cases with moderate diseases and 10.2 ± 0.22 for cases with severe diseases).

In this study, the changes in % yield, dry matter, ash, lipid, protein content, water activity, pH, total volatile basic nitrogen (TVB-N), total viable aerobic count (TVC), yeast and mold count, lactic acid bacteria (LAB), colour parameters and sensorial properties were analysed in rainbow trout (Oncorhynchus mykiss) exposed to either salt only or two different salt-sugar mixture treatments. For this purpose, three groups were formed. For the first, second and third group, fish samples were treated with only salt (S), salt and sugar blend (WS) and salt and brown sugar blend (BS), respectively. Then, the samples were vacuum packaged and stored at +4°C for 3 months. Overall, salt treatments, liquid smoking and cooking as well as storage generally caused remarkable changes in the parameters of interest. However, except for the sensory analysis, not a remarkable change was seen when the three groups were compared among themselves. The results of experienced panelists suggested that group BS samples had superior appearance, taste, odor and texture and therefore expected to be more preferred by the potential consumers.

Interest in unconventional seeds such as Dioclea reflexa is growing in the tropical regions, with the potential for utilisation as food or industrial materials. Researchers confirmed that Dioclea reflexa seed has the potential for clinical use, use as a food source, and as industrial raw material. This research studies the effect of moisture content on the physical properties of Dioclea reflexa seed and the effect of moisture content and compression axes its mechanical properties. Standards methods were used to determine the physical properties, while the mechanical properties were derived from force-deformation curves for the moisture content range 4.8 to 12.1% (wet basis). The mean values of the seed’s length increased by 3.55% (from 31.01 mm), the width increased by 4.13% (from 26.64 mm), and the thickness decreased by 2.48% (from 21.75 mm). The geometric mean diameter increased by 1.68%, surface area increased by 3.68%, sphericity decreased by 1.54% and individual seed mass increased by 10.46%. The physical properties exhibit linear relationships with moisture content. Rupture force increased by 75% (from 0.80 kN) for loading along the major axis; by 84% (from 0.72 kN) for the intermediate axis; and by 41% (from 0.78 kN) for the minor axis. Rupture energy increased from 0.18 J to 1.25 J for compression along the major axis, from 0.087 J to 0.43 J for the intermediate axis, and from 0.080 J to 0.18 J for the minor axis. The mechanical properties were found to be moisture content and loading orientation-dependent. Reducing moisture content reduced both the force and the energy required to rupture the seeds. The data generated will be useful in the design of processing machinery and storage facilities for the seeds.

Investigate the changes that occur in the placenta tissues of pregnant rats that were administered acrylamide (AA) and vitamin E as a protective agent during pregnancy. Thirty rats that were proven positive for pregnancy with vaginal smear test were randomly distributed into control, corn oil, vitamin E, acrylamide and vitamin E + acrylamide groups. Pregnant rats were decapitated on the 20th day of the experiment. Malondialdehyde (MDA), reduced glutathione (GSH), total antioxidant capacity (TAS), total oxidant capacity (TOS) and Xanthine oxidase (XO) levels were measured in placenta tissues. It was determined that acrylamide application during pregnancy statistically significantly increased MDA, TOS and XO levels and reduced GSH and TAS levels in the placenta tissue of pregnant rats when compared to all other groups, and GAS and TAS levels statistically significantly increased in vitamin E administered group when compared to all other groups and TOS and XO levels were decreased to control group levels. It was observed that orally administered AA changed the antioxidant / oxidant equilibrium favoring the oxidants by increasing MDA, XO and TOS levels in pregnant rats and caused oxidative stress, while vitamin E administration returned the antioxidant / oxidant equilibrium back to normal levels, preventing oxidative stress induced toxicity.

Dornelor Basin is characterised by numerous high quality water sources, which is proven by the fact that the main mineral waters on the Romanian market come from this area. The study aimed to provide data on the occurrence and human infective potential of Giardia and Cryptosporidium, as the most important water-borne parasites, from Bistrița river tributaries of Dornelor basin, North-Eastern Romania. Water samples were collected from 10 tributaries of the Bistrita river, from the level of sampling stations set upstream and downstream from the anthropic communities. The harvested water samples were further processed using nonmolecular methods in order to isolate (oo)cysts. Subsequently, the isolated Cryptosporidium and Giardia (oo)ccyst were molecularly characterized through PCR and genomic sequencing, which led to the identification of Giardia in order to identify them at species level. The outcomes revealed the fact that the waters of the emissaries under study have a low parasite load and that, upstream from the human settlements, the water is highly pure when related to the protozoa under study. The increased load of Giardia spp. and Cryptosporidium spp.

This study was carried out during the summer of 2014 to determine alternative quality forage sources that could be grown in the Aydın ecological conditions. In the study, effects of 3 different mixtures and 2 pure species (100% Buckwheat, 25% Buckwheat -75% Soybean, 50% Buckwheat -5 0% Soybean, 75% Buckwheat - 25% Soybean, 100% Soybean) and 2 different harvesting times (50%-100% flowering/buckwheat) on yield and quality characteristics were investigated. According to measurements, the highest average herbage yield was obtained from 75% Buckwheat-25% Soybean application (3100 kg/da) at 2nd harvest time. When the average of hay yield was examined, the results were similar to herbage yield. When ADF and NDF were examined, the highest values were seen at the 2nd harvest. When the crude protein ratios were examined, it was found that they decreased at the 2nd harvesting time and the highest value was determined at 100% soybean application at the 1st harvesting time (21.08%). When Digestible Dry Matter (DDM) and Relative Feed Value (RFV) were examined, the highest values were determined in 100%Soybean applications at first harvest time and when the mixture applications were examined, the highest values were determined to be 75% Buckwheat - 25% Soybean application. As a result of the study, it was determined that the yields obtained at the 2nd harvest time were higher but the forage quality decreased. When the mixtures were examined, it was determined that the mixture having the highest roughage value was 75% buckwheat + 25% soybean application. In this study, the buckwheat which have short vegetation and good quality and the soybean, which is infront of with high quality, mixtures were examined. It has also been found that these mixtures may be important for obtaining high-quality forage in the short and intermediate periods.

In this study 384 Turkish originated oat genotypes obtained from different gene banks, were characterized and evaluated for agronomical traits with four commercial cultivars (Checota, Sebat, Faikbey and Seydişehir) under augmented experiment design for 2012-2013 and 2013-2014 cropping years. Oat landraces were evaluated for stem diameter (SD), plant height (PH), panicle length (PL), vegetative period (VP), grain filling period (GFP), days to maturity (DM), grain number per panicle (GNP), grain weight per panicle (GWP), thousand kernel weight (TKW), lodging (LOD), barley yellow dwarf virus (BYDV) and single row yield (SRY) under Kahramanmaraş conditions. According to the results of field trail for two years, differences of genotypes were significant for SD, PH, PL, VP, DM, TKW and SRY. However, the components such as SD, PL, VP, GFP, DM, GNP, GWP, TKW and SRY were significantly changed for the years and year x genotype interactions were also significant for PL, VP, DM, TKW and SRY. The landraces performed better than the commercial ones for the most of the evaluated traits. The SRW ranged between 4.65 g (TL444) to 202.1 g (TL614). Moreover, the other genotypes with the higher SRY were TL708, TL714, TL734 and TL703 genotypes with 167.85, 160.25, 153.90 and 149.7 g SRY, respectively.

In order to investigate diversity and explain the relationships of essential oil yield with morphological traits, 84 populations T. polycephalum, were sown in the field using randomized complete blocks design (RCBD) with three replicates in Research Institute of Forest and Rangeland, Tehran, Iran in 2013-2014. Data were collected for flowering date, growth degree days (GDD), stem number, plant height, dry matter (DM) yield, essential oil percentage, and essential oil yield. The relationships among traits were determined using correlation, regression and factor analysis. The genetic distance and genotype classification were determined using cluster analysis. DM yield was positively correlated with plant height, canopy cover, stem number and oil yield (ρ<0.01), whereas oil% was negatively correlated with plant height and stem number (ρ<0.05). Result of stepwise regression in which essential oil yield were considered as dependent variable showed that essential oil%, and DM yield accounted for 39.95 and 47.75%, of the total variations in essential oil production, respectively. In factor analysis, the Eigen values obtained from 1 to 3 factors were higher than one with 88.9% of total variations. In the first factor, traits of DM yield, plant height, canopy cover, stems number, and in the second factor flowering date, GDD and oil yield and in the third factor oil% had higher Eigen vector coefficients for genotype classification. In cluster analysis, genotypes were categorized in four groups. According to the obtained results, cluster 1 for early maturity, clusters 3 for plant height canopy cover, stems number, DM yield and essential oil production and cluster4, for essential oil%, had significantly higher mean values than other groups. There was a good agreement between the results obtained from cluster and factor analyses in scatter diagram representation of 84 genotypes based on the first and second factors. It was concluded that population of cluster 3 are capable to breeding improved new cultivars and should be focused on selection higher aerial biomass yield, plant height, flower number, essential oil%, coupled with early flowering date. | Para investigar la diversidad y explicar las relaciones del rendimiento de aceite esencial con rasgos morfológicos, 84 poblaciones de T. polycephalum fueron sembradas en el campo utilizando diseño de bloques completos al azar (BCA) con tres réplicas en el Instituto de Investigación de Bosques y Pastizales, Teherán, Irán en 2013-2014. Los datos fueron colectados para la fecha de floración, días de grado de crecimiento (DGC), número de tallos, altura de planta, rendimiento de materia seca (MS), porcentaje de aceite esencial y rendimiento de aceite esencial. Las relaciones entre las características agronómicas se determinaron mediante correlación, regresión y análisis factorial. La distancia genética y la clasificación del genotipo, se determinaron mediante análisis de conglomerados. El rendimiento de MS se correlacionó positivamente con la altura de la planta, cobertura del dosel, número de tallos y rendimiento de aceite (ρ <0.01), mientras que el% de aceite esencial se correlacionó negativamente con la altura de la planta y el número de tallos (ρ <0.05). El resultado de la regresión gradual en la cual el rendimiento de aceite esencial se consideró como variable dependiente mostró que el% de aceite esencial y el rendimiento de MS representaron 39.95 y 47.75% de las variaciones totales en la producción de aceite esencial, respectivamente. En el análisis de factores, los valores de Eigen obtenidos de 1 a 3 factores fueron mayores que uno con 88.9% de las variaciones totales. En el primer factor, los rasgos de rendimiento de MS, altura de la planta, cobertura del dosel, número de tallos y en la segunda fecha de floración del factor, DGC y producción de aceite esencial y en el tercer factor, % de aceite esencial, tuvieron coeficientes de vectores Eigen más altos para la clasificación del genotipo. En el análisis de conglomerados, los genotipos se categorizaron en cuatro grupos. De acuerdo con los resultados obtenidos, el grupo 1 para madurez temprana, los grupos 3 para cobertura vegetal del dosel, el número de tallos, el rendimiento de MS y la producción de aceite esencial y el grupo 4, para% de aceite esencial, tuvieron valores promedio significativamente más altos que otros grupos. Hubo una buena concordancia entre los resultados obtenidos de los análisis de grupos y factores en la representación del diagrama de dispersión de 84 genotipos en función del primer y el segundo factor. Se concluyó que la población del grupo 3 es capaz de producir nuevos cultivares mejorados y debe centrarse en la selección de mayor rendimiento de biomasa aérea, altura de la planta, número de flores, % de aceite esencial, junto con la fecha de floración temprana.
