Factors such as driving motor vehicles, sedentary occupations, vibration, smoking, previous full-term pregnancies, physical inactivity, increased body mass index (BMI), and a tall stature are associated with symptomatic disc herniations. Fitness and strength is postulated to protect an individual from disc rupture. The objective of our study was to(More)
Metastasis of a follicular thyroid carcinoma (FTC) to the skull is very rare. We present a case of solitary lytic skull metastasis of a FTC in a 30-year-old woman. The patient presented with bulging on the left side of the head. Neuro-imaging techniques showed a lesion with an osteolytic component in the left frontal region. After a left frontal craniectomy(More)
This research aimed to evaluate the effects of partial or total replacement of fish oil (FO) with unrefined peanut oil (PO) on growth and some physiological parameters of Mozambique tilapia juveniles for 60 days. Three triplicate groups (initial weight 6.36±0.19 g) were fed with isoenergetic and isonitrogenous diets in which FO was replaced with PO in(More)
Unrefined peanut oil was evaluated as a partial or total replacement of fish oil in diets for common carp (Cyprinus carpio) and growth performance, feed utilization, and biochemical status were examined. Three isonitrogenous (34.5% protein) and isolipidic (12.8% lipid) experimental diets were fed to satiation to triplicate groups of 10 common carp(More)
The objective of this study is to investigate the effects of dietary protein and lipid levels on the growth performance and bioeconomic benefits of two-banded seabream (Diplodus vulgaris) juveniles, a candidate species for aquaculture sector. Eight experimental diets were formulated with four protein (50, 45, 40 and 35 %) levels for each of the two lipid(More)
Carassius auratus is one of the most significant ornamental and food fishes of the world that is globally distributed and well known. Although it is known to have existed at least for six decades and expanding its distribution range in Turkish waters, there is a dearth of information on genetic structure and variations of goldfish in Turkey. In this study,(More)

We report the rare case of a 43-year-old woman with a simultaneous meningioma of the sphenoid wing and an amyloid-containing prolactinoma. The patient, who presented with a 17-year history of amenorrhea, and galactorrhea, was found to have a 10-mm mass in the pituitary gland. During excision of this lesion, another mass was noticed, which was located in the(More)
Blood parameter assessments of fish may be used as quick tools for diagnosing health status. The aim of this research was to undertake a comparative study of hematological and biochemical parameters of Italian and Turkish farmed rainbow trout Oncorhynchusmykiss(Walbaum, 1792) to establish baseline values in relation to different areas. Forty Italian trout(More)
The present study investigated feed efficiency and growth performance of juvenile Seabass (Dicentrarchus labrax) cultured in tanks with different colors. Triplicate groups of experimental fish were distributed into 12 tanks, which showed four different tank colors, i.e. red, blue, green, and yellow. All the fish in the trial received the same diet for a(More)
