Gueven, Alper; Knorr, Dietrich
Production of aglycone type isoflavonoids, Genistein and Daidzein, and p-glycosidic type isoflavonoids, Genistin and Daidzin, by the soy plant callus suspension culture was investigated in a batch system. Genistein and Daidzein concentrations increased during the exponential growth phase of the biomass. Genistin and Daidzin concentrations were not directly related with biomass production. Methyl jasmonate addition to the growth medium (0.1 kg/m(3)) was found to increase isoflavonoid biosynthesis by 5-6 times. Isoflavonoid production in the 7 days old culture increased with pulsed electric field (PEF) application at 1.6 kV, and aglycone forms were influenced to a greater extent. (C) 2010 Elsevier Ltd.

DANABAS, D., T. ALTUN and F. CELIK, 2011. The overwintering of leaping mullet (Liza saliens Risso, 1810) in fresh water. Bulg. J. Agric. Sci., 17: 846-850 The overwintering of leaping mullet (Liza saliens Risso, 1810) juveniles (average live weight (W) 5.20 +/- 0.02 g and average total length (L) 8.11 +/- 0.08 cm) was investigated, in this study. The trial was planned in 2 groups and triplicate. One of the trial groups (the Group 1) comprised of the fish stocked in ponds in the open area and the other group (the Group 2) of the fish stocked in the ponds covered with greenhouses. The average W and L values of the Group 2 after a period of 3 months were 8.70 +/- 0.04 g and 9.62 +/- 0.05 cm, respectively. The mortality rate (M) in this group was 0.95 +/- 0.1 % and 12.86 +/- 0.1 % in the Group 1. The difference among the W and L values, specific growth rates (SGR) and M averages obtained from the groups was found to be statistically significant (P<0.05). As a result of this study, it can be recommended that mullet species can be polycultured as a side product with aforementioned species in large scale businesses by efficient use of pond layers.

Akansu, Yahya Erkan; Özmert, Mehmet; Firat, Erhan
In this study, the effect of attack angle on vortex shedding phenomena in the case of flow around the square prism as a bluff body and the circular rod which used as flow control component was experimentally investigated. While the value of attack angle equal to 0 degrees, the upstream control rod and square prism are in tandem arrangement to free stream. Experiments were conducted at Reynolds number of 1.0 x 10(4), for the diameter ratio of d/D=0.25, the attack angle between 0 degrees <= alpha <= 90 degrees, and the value of normalized distance between two prism LID is 1, 2, 3, and 4. The velocity measurements were conducted by means of constant temperature anemometer (CTA) as well as vortex shedding frequencies obtained by the spectral analysis of velocity-time history. Characteristics of the vortex formation region and location of flow attachments, reattachments, and separations were observed by means of the smoke-wire flow visualizations. At the angle of attack 0 degrees of the location L/D=2 and 3, the flow structure that possess high vorex shedding frequency which causes remarkable reductions on the drag force and significant increase in the heat transfer was obtained. This flow structure continous to decrease with increasing attack angle up to around 10 degrees. By further increasing of attack angle, the effect of flow control rod on vortex shedding frequency disappears completely.

Alatas, Bilal
This study proposes methods to improve the convergence of the novel optimization method, Big Bang-Big Crunch (BB-BC). Uniform population method has been used to generate uniformly distributed random points in the Big Bang phase. Chaos has been utilized to rapidly shrink those points to a single representative point via a center of mass in the Big Crunch phase. The proposed algorithm has been named as Uniform Big Bang-Chaotic Big Crunch (UBB-CBC). The performance of the UBB-CBC optimization algorithm demonstrates superiority over the BB-BC optimization for the benchmark functions. (C) 2010 Elsevier B.V. All rights reserved.

Staphylococcal food poisoning is one of the most prevalent causes of gastroenteritis throughout the world. This study has three steps. In the first step of the study, different food matrices were analyzed for the presence of Staphylococcus aureus. In the second step, types of staphylococcal enterotoxins (SET) from these foods were analyzed. Lastly, antibiotic resistance of S. aureus isolated was determined using conventional and PCR methods. For this purpose, 300 different food samples were evaluated for contamination with S. aureus. From these samples 221 S. aureus strains were isolated. The same strains were evaluated for antibiotic resistance and existence of mecA gene. All strains were at least resistant to 2 antibiotics, but no MRSA strain was detected. Staphylococcal Enterotoxins (SE) were determined with VIDAS and ELISA from the foods of concern. The results of the analysis held with Vidas SET2 showed 72 (24%) of 300 samples and with ELISA these enterotoxins showed difference in distribution.

Danabas, D.; Benzer, F.; Kaplan, O.; Yildirim, N. C.
Heavy metal pollution of waters is a major environmental problem. Due to their toxicity, long persistence, bioaccumulative and nonbiodegradable properties in the food chain, heavy metals constitute a core group of aquatic pollutants. Capoeta trutta is an economically important fish and the object of significant commercial fishery in the Munzur River. Levels of Cu were measured in samples of the muscle, gill and liver tissues of C. trutta from Munzur River. In liver copper levels were higher at Station I (6.15 mg kg(-1)) polluted by domestic waste than Station II (5.48 mg kg(-1)) (P<0.05). The highest copper level (7.25 mg kg(-1)) was measured in muscle tissue at Station II. There was found no statically differences between stations in gill and muscle (P>0.05). It is suggested that ecological condition of freshwater fish and contamination levels in Munzur River must be regularly monitored.

Yildirim, Numan; Yildiz, Abdunnasir
Biodelignification of cotton stalk (CS) by Pleurotus eryngii collected from Tunceli and Elazig province of Turkey under solid state fermentation (SSF) was studied. The effect of the addition of varying concentration (5 & 10% w/w) of rice bran (RB) on lignin degradation and Carbon/Nitrogen (C/N) ratio were investigated. Klason lignin (KL) degradation was followed for 140 day. While substrate initially contained 28.66% KL, maximum lignin loss (69.68+/-1.05%), occurred on CS +5% RB, C/N ratio of non-fermented cotton stalk initially was 34.13+/-4.98% and after incubation this ratio decreased to 18.60+/-0.36% on CS without RB. It was concluded that P. eryngii strain collected from Tunceli province is very effective in delignifying cotton stalk. (C) 2011 Friends Science Publishers

Kizak, Volkan; Guner, Yusuf; Turel, Murat; Can, Erkan; Kayim, Murathan
The rainbow trout is an intensively cultured species because of its more cultivatable character than the brown trout. In this experiment, the brown trout culture did not expand due to low growth performance compared to that of the rainbow trout. This experiment was conducted in a commercial trout farm, Aegean Area (Turkey). Growth performances and survivals of rainbow and brown trouts from fry to fingerling were observed for 155 days. Growth performances, feed conversion rates and survivals were determined. The initial weights of the rainbow and brown trouts were 0.1 +/- 0.01 g. Final weights were 26.5 +/- 5.19 g and 12.97 +/- 2.74 g, respectively at the end of experiment. Survival and FCR of rainbow and brown trouts were 83.9 and 80%; 0.59 and 0.61 respectively. As a result, there is a similarity between these two trout species in point of survivals and FCR's although growth performance of the rainbow trout was significantly better than that of the brown trout.

Kandemir, F. M.; Issi, M.; Benzer, F.; Gül, Y.; Basbug, O.; Özdemir, N.
The aim of the present study was to investigate the plasma nitric oxide concentrations and the erythrocyte arginase activities in lambs with contagious ecthyma, which frequently occurs in lambs and goat kids. The study was conducted on 10 Akkaraman, 1-2 month old lambs with contagious ecthyma (the clinical diagnosis was based on the presence of typical cauliflower-like proliferative lesions in lips, commissum labials, nostrils and udders) and on 10 apparently healthy lambs (controls) from the same flock. Plasma NO concentrations and erythrocyte arginase activities were determined on all animals using the Griess method and the thiosemicarbazide diacetylmonoxime urea (TDMU) method, respectively. Compared to the control group, the mean plasma NO concentration was significantly increased in the diseased group while the mean arginase activity was markedly depressed. Abnormally high NO concentrations and low enzyme activities were observed in 9 and 10 diseased lambs, respectively. Additionally, a negative correlation was evidenced between the 2 biochemical parameters. These results show that this viral infection is associated with some perturbations in the arginine metabolism, leading preferentially to the synthesis of NO, which is presumed to exhibit some antiviral properties.

In this study, the diazotized p-nitroaniline and p-methylaniline were coupled with malononitrile. The ring closure reaction of the obtained products with hydrazine monohydrate yielded 4-(4-methylphenylazo)-1H-pyrazole-3,5-diamine (L-1) and 4-(4-nitrophenylazo)-1H-pyrazole-3,5-diamine (L-2). The structure of the ligands has been elucidated by spectroscopic analyses. Then, novel Ni(II) and Cd(II) complexes of the ligands have been synthesized and the structures of these complexes determined by elemental analysis, spectrometric and TGA/DTA methods, molar conductance and magnetic susceptibility measurements. All the complexes were monomeric and diamagnetic. From the elemental analyses and mass spectra data, the complexes were proposed to the formulae [Ni-2(L-1)(2)(OH)(2)]center dot 2Cl center dot 8.5H(2)O, [Cd-2(L-1)(2)(OH)(2)]center dot 2Cl center dot DMF center dot 3H(2)O, [Ni(L-2)(2)]center dot 2Cl center dot 2DMF center dot 7H(2)O and [Cd-2(L-2)(2)(OH)(2)(H2O)(4)]center dot 2Cl center dot 1.5H(2)O. For the Cd(L-2) complex octahedral geometry was proposed, but the Ni(L-1), Ni(L-2) and Cd(L-1) complexes show four coordinated structure. The Ni(L-1), Cd(L-1) and Cd(L-2) complexes were found to be dinuclear. On the other hand the Ni(L-2) complex was found to be mononuclear. All the complexes were found to be (1:2) electrolytes.

The aim of this study is to evaluate the protective effect of pomegranate seed extract on cisplatin-induced oxidative stress in rabbits testes. Rabbits were divided into three groups; (i) being control group, (ii) cisplatin group and (iii) cisplatin + pomegranate seed extract group. The level of malondialdehyde and glutathione, the activity of catalase, glutathione peroxidase, were measured in testes tissue of rabbits. Malondialdehyde levels were increased depending on cisplatin. In the case of cisplatin + pomegranate seed extract, malondialdehyde levels were found to be lower than cisplatin group (p < 0.05). In cisplatin group, catalase, glutathione peroxidase activity and glutathione levels were decreased when compared to control but in cisplatin + pomegranate seed extract group, catalase, glutathione peroxidase activity and glutathione levels were found higher than cisplatin group (p < 0.05). The pomegranate seed extract supplementation may play a protective role or decrease the side effects of cisplatin-induced testes toxicity from cancer medicines.

Curcumin, a widely used spice and colouring agent in food, has been shown to possess potent antioxidant, antitumor promoting and anti-inflammatory properties in vitro and in vivo. The present study was designed to investigate the protective effects of curcumin on changes in the levels of lipid peroxidation and endogenous antioxidants induced by cisplatin (cis-diamminedichloroplatinum II, CDDP) in the testiclular tissue of rabbits. 18 healthy male New Zealand white rabbits were equally divided into three groups of six rabbits each, control, cisplatin, and cisplatin+curcumin. The degree of protection produced by cisplatin was evaluated by determining the level of malondialdehyde (MDA) and glutathione (GSH), the activity of catalase (CAT), glutathione peroxidase (GSH-Px), were estimated from testes homogenates. MDA levels were increased with cisplatin compared to control but in cisplatin+curcumin group, MDA levels were found to be lower than cisplatin group (p<0.05). The activity of CAT and GSH-P-X was decreased in cisplatin and cisplatin+curcumin groups compared to control (p<0.05). In the case of cisplatin+curcumin CAT and GSH-Px activity were increased compared to cisplatin group (p<0.05). GSH levels were decreased with cisplatin but administration cisplatin+curcumin increased the levels of GSH comared to cisplatin group (p<0.05). In the present study, co-administration of curcumin with cisplatin prevented the damage to testes induced by this drug and may be considered as a potentially useful candidate in the combination chemotherapy with cisplatin.

The objective of the study was to characterize the effects of sex on lipid peroxidation (as malondialdehyde, MDA), antioxidant defence system (as glutathione peroxidase, GSH-Px) in the hepatopancreas, gonad and muscle tissues of freshwater crayfish, Astacus leptodactylus, in culture condition. The crayfish used in the present study was provided from Keban Dam Lake population of A. leptodactylus. 34 males and 30 females crayfish in different size were hold in stock ponds (6 x 6 x 0.5 m). This study was carried out between June 18, 2004 and December 1, 2004 at the crayfish reproduction unit of Aquaculture Faculty of Firat University, Elazig, Turkey. Plastic pipes (20 cm in length and 7 cm in diameter) were provided as shelters for the crayfish. Crayfish were fed 2 % of their total wet weight daily with prepared ration. Crayfish were exposed to natural photoperiod. During the study, the mean water temperature, dissolved oxygen and mean pH were 4 degrees C, 6.28 +/- 0.32 mg L-1 and 7.82 +/- 0.17, respectively. MDA and GSH-Px levels according to sex and tissue-species were determined. MDA level in the hepatopancreas and gonad of females were higher than males, except muscle tissue (P<0.001). However, the GSH-Px activities in the hepatopancreas and gonad of males were higher than females, except muscle tissue (P<0.001). As a result, MDA and GSH-Px levels in the hepatopancreas, gonad and muscle tissues of freshwater crayfish, Astacus leptodactylus, in culture condition changed both tissues and sex.
