Scorpionfish (Scorpaena porcus) is a demersal fish
species commercially important for its of which meat is tough
and delicious. The aim of this study was to determine heavy
metal (Al, Cu, Ni, As, Cd, Hg, Pb, U) concentrations in this
fish species which is traditionally consumed in the Black Sea
Area and, to compare the concentrations of various toxic elements
in different organs of the fish specimens (muscle, liver,
gill, and skin). Within this scope, the mineralization was performed
using microwave digestion system. Thirty-two scor
pionfish caught from Sinop Inland Port during 2010 w ...Daha fazlası
Objective: To study and compare the effects of different demineralizationinhibition
methods on the shear bond strength (SBS) and fracture mode of an
adhesive used to bond orthodontic brackets to demineralized enamel surfaces.
Methods: Eighty freshly extracted, human maxillary premolars were divided
into 4 equal groups and demineralized over the course of 21 days. Brackets were
bonded to the demineralized enamel of teeth in Group 1. In Group 2, bonding
was performed following resin infi ltration (ICON®, DMG, Hamburg, Germany).
Before bonding, pre-treatment with acidulated phosphate fluor ...Daha fazlası
The aim of this prospective experimental study was to evaluate the effect of light-emitting diode (LED) photobiomodulation therapy (LPT) on the stability of immediately loaded miniscrews under different force levels, as assessed by resonance frequency analysis (RFA). Sixty titanium orthodontic miniscrews with a length of 8 mm and a diameter of 1.4 mm were implanted into cortical bone by closed flap technique in each proximal tibia of 15 New Zealand white adult male rabbits (n = 30). The animals were randomly divided into irradiated and control groups under different force levels (0, 150, and 3 ...Daha fazlası
2020 is the International Year of the Nurse and Midwife and the 200th anniversary of Florence Nightingale’s birth; a year meant for celebration, and a deeper look at the importance of the nursing role in the future of healthcare. Today, due to the COVID-19 pandemic, the role of the nurse and the urgent need for investment of this precious resource is at the forefront of many health policy makers’ agendas. As we entered 2020, many countries were already facing a nursing shortage. The World Health Organization’s first State of the World’s Nursing report, launched in April this year, reported a g ...Daha fazlası
Mobility is the basic need for functionality in human life. Physically disabled people often require mobility aids and wheelchairs are the most commonly preferred assistive mobility devices for enhancing independent functional mobility. Today, powered and manual wheelchair technology is available. Manual wheelchair propulsion necessitates more repetitive loading, but because the human body is not designed for such movement, musculoskeletal and functional issues such as pain and joint limitation may arise among manual wheelchair users. They require more support from their spine, arm, elbow, and ...Daha fazlası
Objective: This study was conducted to determine hemolysis rates for venous blood samples drawn by injector and vacutainer holder and to assess the effect of the venipuncture technique on the process of hemolysis. Material and Method: This cross-sectional and analytical study was conducted with 128 patients who were admitted to the Cardiology and Angio clinics of a university hospital and met the inclusion criteria. One group of patients who were to have routine biochemical tests underwent venipuncture with an injector, and another group with a vacutainer. Results: The serum hemolysis level is ...Daha fazlası
The study was performed between March 2009
and March 2010 at the Sinop Inner Harbor on cultured
mussels at the offshore submerged longline system. The
samples of mussels, sediment and suspended particulate
matter were seasonally taken for the purpose of monitoring
differences of metal contents. In addition, burnable organic
matter, contamination factors (CF), pollution load index
(PLI) in sediment samples, meat yield of mussels were
seasonally determined. All metals in suspended particulate
matter were found to be above the national limit. Cd
concentration in sediment was above the l ...Daha fazlası
Objective: The study aimed to investigate the spiritual needs of oncology patients and spiritual care competencies of oncology nurses caring for the oncology patients. Material and Method: The study has a descriptive and cross-sectional design. The study was carried out with oncology patients (n=324) and oncology nurses (n=17) who were caring for them in oncology unit of a hospital in the city of İzmir, Turkey. The study data were collected using the Spiritual Needs Scale for the patients and the Spiritual Care Competency Scale-T for the nurses. In statistical analysis, number, percentile, mea ...Daha fazlası
This study investigated Holothuria tubulosa, Gmelin 1791 in the Dardanelles Strait from April 2013 to March 2014, in order
to outline the morphological characteristics, reproductive patterns and the relationship between population characteristics and
environmental parameters. 15 to 30 individuals of this species were sampled monthly at three stations. There was a negative allometry
between length and weight, with gutted weight being the most reliable measurement for this species. The reproductive
patterns of the species were identified for the first time for examples from the Turkish coast ...Daha fazlası

Introduction: The aim of this study was to determine the peri-miniscrew implant crevicular fluid receptor
activator of nuclear factor-lB ligand (RANKL) and osteoprotegerin (OPG) levels around loaded and unloaded
miniscrew implants at different time intervals. Methods: Twenty loaded and 16 unloaded miniscrew implants
were included in this study. All miniscrew implants were placed bilaterally between the maxillary second premolars
and first molars as anchorage units for canine distalization. Peri-miniscrew implant crevicular fluid was taken
from the mesiobuccal aspects of the loaded and unl ...Daha fazlası
The levels of heavy metals viz., Cd, Cu, Fe, Ni, Pb, Zn and Al were determined by ICP-AES in the
muscles and total bodies of Mullus barbatus (Linnaeus 1758), Trachurus trachurus (Linnaeus 1758),
Engraulis encrasicolus (Linnaeus 1758) captured from the coast of Sinop. The order of the levels of
the heavy metals in the total fish samples was Fe > Zn > Al > Pb > Cu > Ni > Cd, whereas in the
muscles, the order was Zn > Fe > Cu > Al > Pb > Ni > Cd. The experiment results are discussed by
comparison with literature values.
