Reproductive Characteristics of Brown Trout (Salmo trutta fario L.) Reared in North-Eastern Turkey

Abstract Spawning time, fecundity, fertilization rate, and egg size of brown trout (Salmo trutta fario) reared in north-eastern Turkey were investigated. Seventeen females were stripped into separate bowls and eggs were fertilized by milt from at least two males. Spawning lasted from mid-November to early January. The mean brood size was 989.4±620.53 g and mean total and relative fecundities were 2029±2051 eggs/individual and 2259±947 eggs/kg body weight, respectively. Mean egg diameters and weights were 5.3±0.40 mm and 93.9±19.37 mg. The mean fertilization and hatching rates were 95.4±4.60% and 83.3±11.79% of the total number of eggs. Correlations were positive between body weight and total (r 2 = 0.8665, p<0.001) and relative (r 2 = 0.1632, p>0.10) fecundity, and negative between egg diameter and body weight (r 2 = -0.002, p>0.10) and total fecundity (r 2 = -0.0865, p>0.05). Our findings suggest that reproductive parameters of brown trout under culture conditions in north-eastern Turkey are similar to those of other salmonid species

Right lung agenesis and left lung bronchiectasis

A 30-year-old man was diagnosed to have right lung agenesis and left pulmonary bronchiectasis after diagnostic workup for dyspnea developed during hemodialysis due to CRF. We report this patient as case report because he had a longer survival and no associated systemic malformation though right-sided lung agenesis contrary to data in the literature. © 2005 Elsevier Ltd.

Experimental Investigation of a Vehicle Fuel Tank Sloshing Behavior

Bu çalışmada bir binek araç yakıt tankı içinde meydana gelen çalkalanma hareketi deneysel olarak incelenmiştir. Öncelikle yakıt tankının çalkalanma deneylerinin yapılacağı deney tesisatının tasarımı ile ilgili bilgi verilmiştir. Tankın farklı doluluk oranları ve uyarı yönleri için perdeli ve perdesiz tipteki yakıt tanklarında deneyler yapılmıştır. Tanka sinusoidal giriş verilmiş ve tank üzerindeki çeşitli noktalardan alınan basınç sinyalleri ile tankın ivme sinyali toplanarak yorumlanmıştır.In this study, sloshing behavior of a passenger car’s fuel tank is investigated experimentally. Firstly, detailed information is given about experimental system. After studies is continued on the baffled and unbaffled tanks. The system behavior is also examined for different fluid filling rate, different excitation conditions such as transverse and longitudinal. Sinusoidal input is given as input to the system and acceleration and pressure signals taken from different points of the tank are evaluated

Role of ankle brachial index measured by simple automatic sphygmomanometers in predicting postoperative kidney function in patients undergoing major cardiac surgery

Introduction: Ankle-brachial pressure index is an objective, noninvasive test for predicting subclinical atherosclerotic diseases. We investigated the role of ankle-brachial pressure index measured with automated sphygmomanometer devices in the prediction of the development of acute kidney injury in patients undergoing major cardiac surgery. Methods: This single-centered, cross-sectional, and observational study was performed on 80 (66 males and 14 females, 58 +/- 10 years) patients undergone cardiac surgery. Complete anamnesis, laboratory tests, intravenous fluids, medications, blood products, and all perioperative procedures were recorded in all patients before the surgery. Two automated sphygmomanometer devices giving equivalent results were used for measuring Ankle-brachial pressure index. The data in the first two days after the surgery were used for analysis. The criteria of AKIN were used in the diagnosis of acute kidney injury. Results: Twenty-one (23%) patients developed acute kidney injury in the postoperative period. None of the patients needed renal replacement therapy or died. There was no significant difference between mean ankle-brachial pressure index levels of patients with and without acute kidney injury (1.04 +/- 0.17 and 1.06 +/- 0.19, respectively, p=0.554). The mean ankle-brachial pressure index was significantly lower in patients with perioperative complications that cause hemodynamic instability (1.07 +/- 0.14, 0.96 +/- 0.13, p=0.016). On the multivariate analysis model, only perioperative hemodynamic complication development was found to be related to postoperative acute kidney injury. Conclusion: Anklebrachial pressure index may have a role in predicting perioperative hemodynamic complications, which may cause acute kidney injury in patients undergoing major surgery. Simple automatic blood pressure devices can be used in daily practice for ankle-brachial pressure index measurement instead of complex and expensive doppler devices

Improving the reproductive yield of Black Sea Salmon (Salmo labrax PALLAS, 1814) with a selective breeding program

This study aimed to improve some culture characteristics of Black Sea salmon (Salmo labrax) culture generations through a classical selective breeding program. Thus, the success of the applied program was examined by comparing the reproduction time and proportional distribution of the wild broodstock (F-0) individuals with the F-1, F-2, F-3 and F-4 generation broodstocks adapted to the culture conditions. According to the results, gamete uptake from the new generations occurred between October and February. The highest egg uptake was determined for all generations in December. While the difference between wild (F-0) broodstock and F-1, F-2, F-3, and F-4 generations was statistically significant in favor of new generations (P<0.05), the difference was insignificant between hatchery origin-new generations. Mean egg diameters were low in F-2 and F-3 generations, and F-0, F-1 and F-4 generations were found to be higher than the others (P<0.05). It was calculated that the fertilization rate was higher in F-3 and F-4 generations, similar in F-1 and F-2 generations, and lower in F-0 generation than the others (P<0.05) at the end of the study. Through the selection program, it was determined that the adaptation of the species to the culture conditions improved, the reaction to human activities declined, and homogeneous distribution in tanks/ponds was relatively achieved from the F-2 generations. As a result, it has been determined that F-4 generation broodstock have higher culture performance than other generations. Producers of this species should use F-4 broodstock for efficient and economical production.General Directorate of Agricultural Research and Policies (TA-GEM) , Ministry of Agriculture and Forestry, Republic of Turkiye TAGEM/HAYSUD/2001/07/01/20 TAGEM/HAYSUD/2006/09/03/02 TAGEM/HAYSUD/2011/09/01/0
