Age, growth and reproductive properties of an invasive species Carassius gibelio (Bloch, 1782) (Cyprinidae) in the Ikizcetepeler Dam Lake (Balikesir), Turkey

Background and Purpose: The Prussian carp Carassius gibelio is well known as a hazardous fish species for native fish communities. Ikizcetepeler Dam Lake inhabits some fish species as Cyprinus carpio, Leuciscus cephalus, and Barbus species. The dam lake has major economic importance to the area for both fisheries and drinking water. The reason to select C. gibelio was due to the dominant species in stagnant and slow running waters and possible harmful interactions with native species. Materials and methods: A total of 480 specimens of C. gibelio were monthly collected by gill nets during a 1-year period from Ikizcetepeler Dam Lake. Age was determined from scales. Length-weight relationships, von Bertalanffy equation were used to estimated for growth. Sex were determined by macroscopic observation of gonads. Spawning period of this species was determined according to gonado-somatic index (%). Results: Females and males reached a maximum age groups of VI. Total length was 23.6–31.3 cm in females and 23.0–31.4 cm in males. The male and female ratio was 1:3.52 (M:F) in the favor of females. The Von Bertalanffy growth equations (in length) were found as Lt= 34.89.(1-e–0.11(t+7.66)), Lt= 32.09 (1-e–0.23(t+5.83)) for females and males, respectively. The estimated b values were given as 2.886 and 2.981 for females and males, respectively (b<3). The condition of the fish increased during early summer. Spawning period of this species occured between April and July. Conclusions: With a comparison of the relevant literature, the studied Prussian carp population was characterized by a shorter life span and more rapid growth during the first years of life. These can be considered as typical features of invasive species

Growth, sex ratio, and reproduction of striped red mullet (Mullus surmuletus L.) were determined from 520 specimens collected in the northwestern Aegean coast of Turkey from September 2009 to July 2010. Total length ranged from 7.7 to 17.0 cm while weight varied between 3.50 and 58.9 g. According to the length-weight relationship, positive allometry was confirmed for both sexes. The sex ratio was skewed in favour of males (1:1.73). The monthly values of gonadosomatic index (GSI) of females indicated that spawning occurred mainly between April and September with a peak in July. Values of Condition factor (CF) and Hepatosomatic index (HSI) varied between 0.71-1.57 and 0.10-1.43, respectively.Starost, rast i smrtnost trlje kamenjarke, (Mullus surmuletus L.) procijenjene su kod 520 jedinki prikupljenih na sjeverozapadnoj obali Egejskog mora, Erdemitski zaljev u Turskoj od rujna 2009. do srpnja 2010. Ukupna duljina jedinki je u rasponu od 7,7 do 17,0 cm, a masa je kolebala između 3,50 i 58,9 g. Prema dužinsko-težinskom odnosu, ustanovljena je pozitivna alometrija za oba spola. Omjer zastupljenosti spolova bio je u korist mužjaka (1: 1,73). Mjesečne vrijednosti gonadosomatskog indeksa (GSI) za ženke pokazuju da se mrijest obavlja posebice u razdoblju travanj - rujan, sa vrhuncem u srpnju. Vrijednosti kondicijskog faktora (CF) i hepatosomatskog indeksa (HSI) kolebali su između 0.71-1.57 i 0.10-1.43, respektivno

Microencapsulation of phycocyanin by spray-drying method: Effect of process parameters and wall materials

Spray-drying method was used for the microencapsulation of the extracted, purified phycocyanin from Arthrospira platensis to increase its stability and usability as a food colorant. The effect of process conditions - wall material type, ratio, and inlet-air temperature - on physical and chemical properties was investigated. The moisture content and water activity of phycocyanin microcapsules were found as 1.80-3.18% and 0.15-0.24, respectively. The product with the largest particle size was 19.44 mu m. Size distribution values were in 1.87-6.05. Optimum process condition was determined as 34.4% maltodextrin, 65.6% whey protein isolate, and 167.6 degrees C inlet temperature. Moisture content (2.35%), aw (0.18), Tg (58.25 degrees C), D[4,3] (11.92 mu m), size distribution (2.016), color properties (L*: 79.37, a*: -6.69, b*: -5.29), total phenolic content (12.14 mgGA/L), and microencapsulation efficiency (87.11%) of the phycocyanin microcapsules were also determined at optimum. Microencapsulation efficiency increased with the maltodextrin and whey protein isolate together; the conditions of process variables were effective in the encapsulation process. Novelty impact statement Phycocyanin was prepared in a double-layer emulsion and dried in a spray dryer, thus preventing degradation caused by environmental factors. The physical and chemical properties of the final product were examined and modeled. The conditions required to obtain the microencapsulated phycocyanin with optimum properties were examined.Cost Action [ES1408]; Scientific and Technological Research Council of Turkey (TUBITAK) [115O578]; Scientific Research Commission of Ege University [15 MUH/025]This work was supported by the Cost Action [ES1408]; The Scientific and Technological Research Council of Turkey (TUBITAK) [115O578]; the Scientific Research Commission of Ege University [15 MUH/025]

Optimization of phycocyanin extraction from Spirulina platensis using different techniques

8th International Congress on Pigments in Food - Coloured Food for Health Benefits -- 2016 -- Cluj Napoca, ROMANIAWOS: 000437052500011Phycocyanin is an important commercially available blue food colorant. Herein we report an optimization study of various phycocyanin extraction methods from Spirulina platensis cyanobacterium biomass (dry, frozen and wet). Three different solvents i.e. distilled water, Na-Phosphate pH: 7.4 suspension and 1.5% CaCl2 (w/v) water solution were applied as the extraction medium. The highest total phycocyanin content (55.33 mg/g) was extracted from frozen biomass using 1.5% CaCl2 (w/v aq.) solution. Process variables of classical, ultrasound and microwave extraction methods (biomass/solvent ratio, extraction time, vibration, speed, and power) were optimized considering the CCRD experimental design to enrich phycocyanin. The optimum conditions of extraction methods; classical, ultrasound and microwave were determined as: 1.71% biomass/solvent ratio, 6237.66 homogenization rate and 15 min extraction time; 1% biomass/solvent ratio, 60% amplitude and 16.23 min extraction time; 2.34% biomass/solvent ratio, 133.29 W and 165.96 s extraction time. Classical extraction method provided vivid blue color, a higher amount of phycocyanin, and maximum antioxidant activity as compared to other extraction methods.Cost actionEuropean Cooperation in Science and Technology (COST) [ES1408]; Scientific and Technological Research Council of TurkeyTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [TUBITAK-115O578]; Council of Scientific Research Projects of Ege University, Turkey [BAP-15MUH025]This study was a part of Cost action ES1408 and the authors would like to thank The Scientific and Technological Research Council of Turkey (TUBITAK-115O578) for financial support and Council of Scientific Research Projects (BAP-15MUH025) of Ege University, Turkey

The mean score of NSPBS was determined to be 122 (29-135). Hence, the nursing students' ability to perform professional behaviours was found to be high

Methylsulfonylmethane Induces p53 Independent Apoptosis in HCT-116 Colon Cancer Cells

Methylsulfonylmethane (MSM) is an organic sulfur-containing compound which has been used as a dietary supplement for osteoarthritis. MSM has been shown to reduce oxidative stress and inflammation, as well as exhibit apoptotic or anti-apoptotic effects depending on the cell type or activating stimuli. However, there are still a lot of unknowns about the mechanisms of actions of MSM. In this study, MSM was tested on colon cancer cells. 3-(4,5-Dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) assay and flow cytometric analysis revealed that MSM inhibited cell viability and increased apoptotic markers in both HCT-116 p53 +/+ and HCT-116 p53 −/− colon cancer cells. Increased poly (ADP-ribose) polymerase (PARP) fragmentation and caspase-3 activity by MSM also supported these findings. MSM also modulated the expression of various apoptosis-related genes and proteins. Moreover, MSM was found to increase c-Jun N-terminal kinases (JNK) phosphorylation in both cell lines, dose-dependently. In conclusion, our results show for the first time that MSM induces apoptosis in HCT-116 colon cancer cells regardless of their p53 status. Since p53 is defective in &gt;50% of tumors, the ability of MSM to induce apoptosis independently of p53 may offer an advantage in anti-tumor therapy. Moreover, the remarkable effect of MSM on Bim, an apoptotic protein, also suggests its potential use as a novel chemotherapeutic agent for Bim-targeted anti-cancer therapies

RELIABILITY AND VALIDITY OF THE READINESS FOR INTERPROFESSIONAL LEARNING SCALE (RIPLS) IN TURKISH SPEAKING HEALTH CARE STUDENTS

WOS: 000434980000042Objectives: The purpose of the study was to provide psychometric evaluation of the Turkish version of the Readiness for Interprofessional Learning Scale (RIPLS). Material and methods: This cross-sectional study was carried out with 213 students at the Faculty of Medicine, Faculty of Dentistry and Faculty of Health Sciences. The construct validity of the Turkish version of the scale was analyzed with confirmatory factor analysis (CFA). To determine the reliability of the scale, the Cronbach's alpha coefficient was calculated. In addition, for the assessment of the discrimination of each item on the scale, the top and bottom 27 % from the groups that received the lowest and highest scores from the scale were compared. Results: Standardized coefficients determined with the CFA in the Turkish version of the scale ranged between 0.34 and 0.85 in the students (Except for Item 18). The explained variance values for the items other than item 18 ranged from 0.11 to 0.72. t-values of all the factor loadings were significant. According to the reliability studies of the RIPLS, the internal consistency of Cronbach's Alpha was 0.85 for the overall scale. The t-test results showed that all the items significantly discriminated between students of high and low performance (t: 99.57; p=0.01). Conclusion: As a result, it can be said that the validity and reliability study of the RIPLS administered to Turkish healthcare students indicated that the scale was capable of measuring the Turkish-speaking students' readiness for interprofessional education
