Significance of Physiological and Biochemical Approaches for Black Sea Fishery Investigations

Physiological and biochemical methods are important tools for solving certain fishery problems, such as observed trends of fish distribution and migrations; estimation of productivity of commercial species; indicators and monitoring of stock condition and separating populations. In the review, major results of related long-term studies are presented

Assessment of anti-sperm antibodies in couples after testicular sperm extraction

Purpose: Testicular spermatozoa can be retrieved successfully by the testicular sperm extraction (TESE) procedure and used for intracytoplasmic sperm injection. Disruption in the blood-testis barrier can lead to the production of antisperm antibodies (ASA). The aim of this prospective study was to investigate the frequency of ASA formation in couples after TESE procedure. Methods: Thirty-seven couples were included in the study at the Urology Clinic of the Dr. Zekai Tahir Burak Women’s Health Training and Research Hospital. History, physical examination, spermiogram, and endocrine profiles were obtained for all male patients. All the male patients in this study had been diagnosed with nonobstructive azoospermia (NOA) and underwent microdissection TESE. Secondary and tertiary cases were also included in the study. Serum samples were obtained from all 74 patients before TESE, and at three and 12 months after TESE. Serum ASA levels were determined. ANOVA was performed for statistical analysis for serum Follicle-Stimulating Hormone (FSH), testosterone and testicular volume. P < 0.05 was considered significant. Results: There were no differences in the testicular volumes, serum FSH and testosterone levels before and after TESE. None of the patients or their partners developed significant levels of ASA as a result of the TESE procedure. Conclusion: TESE procedure does not cause ASA production in either males or their female partners

Development of Calanus euxinus during spring cold homothermy in the Black Sea

In copepodites and adults of Calanus euxinus abundance, body length and weight, chemical composition and respiration rate in relation to age were studied during the cruise of R/V 'Knorr' in April 2003 in the southwestern Black Sea and in laboratory experiments. Data on morphology and physiology of C. euxinus collected during other seasons were also used in comparative analyses. At high concentrations of the diatom Proboscia alata during spring homothermy (6.8 to 8.5 degrees C) C. euxinus did not undertake diel vertical migrations to the oxygen minimum zone (OMZ). The majority of the population was located above the OMZ, feeding on phytoplankton during nighttime and daytime whilst nearly 10%, of copepodite stages IV and V (CIV and CV) and adults remained constantly in the OMZ. Although a diapausing stock of the population began to form in the OMZ, the majority of CV developed without diapause. The development times of copepodite stages at 8 C were determined on the basis of field observations of ontogenetic changes in carbon content and calculated absolute growth rates. Development time from CI to CV amounted to 22 d. In CV the time for lipid deposition from 0.008 +/- 0.007 mm(3) in postmolts up to a maximum volume of 0.165 +/- 0.054 mm(3) in intermolts constituted 26 d. The total generation time from eggs to adults is not less than about 66 d

Present Condition of Small Pelagic Fishes in the Black Sea

Recent data on the fat content and abundance of sprat and anchovies are considered here along with data related to sea temperatures and phytoplankton biomass. Findings showed that signicant changes in fish conditions were strongly related to environmental factors

FDG and FDG-labelled leucocyte PET/CT in the imaging of prosthetic joint infection

Purpose The demand for arthroplasty is rapidly growing as a result of the ageing of the population. Although complications such as heterotrophic ossification, fracture and dislocation are relatively rare, differentiating aseptic loosening, the most common complication of arthroplasty from infection, is a major challenge for clinicians. Radionuclide imaging is currently the imaging modality of choice since it is not affected by orthopaedic hardware. Whereas FDG PET/CT imaging has been widely used in periprosthetic infection, it cannot discriminate aseptic from septic inflammation. In this study we aimed to evaluate the role of FDG PET/CT and FDG-labelled leucocyte PET/CT in the diagnosis of periprosthetic infection

Relationship of aortic knob width with cardio-ankle vascular stiffness index and its value in diagnosis of subclinical atherosclerosis in hypertensive patients: a study on diagnostic accuracy

Conclusion: Observation of aortic knob on chest X-ray in hypertensive patients may provide important predictive information of subclinical atherosclerosis. (Anadolu Kardiyol Derg 2012; 12: 102-6
