Determination of 16 European Priority Polycyclic Aromatic Hydrocarbons in Doner Kebab Varieties Cooked Under Different Heating Sources.

Doner kebab is a traditional Turkish meat product produced from lamb, beef or poultry meat seasoned with a blend of spices such as salt, black pepper, cumin, thyme and/or sauces. The aim of this study was to determine 16 EU priority polycyclic aromatic hydrocarbons (PAHs) in doner kebabs cooked under four different heating sources (electricity, open gas, wood and charcoal grilling). For this purpose, 200 meat doner and 200 chicken doner kebab samples were obtained randomly from various buffets and restaurants located in Istanbul and analyzed by means of GC-MS.

Characterisation and Antibiotic Susceptibility Profile of Isolated from Chicken Carcasses.

Introduction: is a Gram+, anaerobic, spore-forming, rod-shaped bacterium that can produce toxins, and it is mainly because its virulence is attributed. The objective of this study was to evaluate the presence of and hyper virulent ribotypes in chicken carcasses and the antibiotic susceptibility of isolated strains.

Material And Methods: was isolated from chicken carcasses by microbiological methods, its ribotypes were identified by means of PCR, the toxin production ability was defined by ELISA, and the susceptibility of the isolates to selected antibiotics was determined by minimum inhibitory concentration evaluator strips.

Detection, Characterization and Antibiotic Susceptibility of in Meat Products.

is a Gram (+), anaerobic, spore forming, rod shaped bacterium that can produce toxin. The objective of this study is to reveal the presence of in meat products, to analyze the ribotype diversity by PCR and to evaluate the antibiotic susceptibility of isolated strains. The organism was isolated in 22 out of 319 (6.

The prevalence of Clostridium difficile in cattle and sheep carcasses and the antibiotic susceptibility of isolates.

Clostridium difficile is an anaerobic, spore forming, rod shaped bacterium frequently isolated from butchery animals in recent years. The aim of this study is to evaluate the presence of C. difficile (especially ribotype 027 and 078) in cattle and sheep carcasses and to investigate the antibiotic susceptibility of isolates.

Microbiological quality of ice and ice machines used in food establishments.

The ice used in the food industry has to be safe and the water used in ice production should have the quality of drinking water. The consumption of contaminated ice directly or indirectly may be a vehicle for transmission of pathogenic bacteria to humans producing outbreaks of gastrointestinal diseases. The objective of this study was to monitor the microbiological quality of ice, the water used in producing ice and the hygienic conditions of ice making machines in various food enterprises.

Estrogen- and Progesterone-Induced Variation in Corneal Parameters According to Hormonal Status.

Objectives: To determine the effects of estrogen and progesterone on corneal thickness, curvature, and biomechanics in healthy corneas according to hormonal status.

Methods: The study included four groups of females: group A (menstruating, not pregnant, not lactating, and not menopausal; n=100), group B (pregnant; n=50), group C (lactating; n=50), and group D (menopausal; n=50). Group A was subdivided according to age, as subgroup A15-25 (age 15-25 years) and subgroup A>25 (age >25 years).

Determination of mould and aflatoxin contamination in tarhana, a Turkish fermented food.

Tarhana is a popular traditional Turkish cereal-based fermented food product mainly produced at home or at home-scale level. Some certain mould species can grow even at low moisture and pH values and produce aflatoxins in food. This study was conducted to determine aflatoksin levels in tarhana.

Effects of electrical stimulation on meat quality of lamb and goat meat.

Effect of various voltage of electrical stimulation (ES) on meat quality of lamb and goat was investigated by using a total of 36 animals at 3-5 years old. Constant 50 Hz frequency and 50, 100, and 250 V, 90 sec of ES were administered to 1/2 carcasses and were examined according their textural, physicochemical, and sensorial characteristics. ES decreased the pH values of lamb and goat meat, and accelerated the rigor mortis (P < 0.

The evaluation of oxidative stress in patients with chronic renal failure.

Background: Free radical-mediated changes are thought to be involved with atherosclerosis in patients with chronic renal failure.

Methods: The protein carbonyl and malondialdehyde (MDA) levels in serum as the markers of radical-induced protein and lipid oxidations were measured in chronic renal failure patients.

Results: Serum carbonyl and MDA levels in both hemodialysis and peritoneal dialysis patients were not found to be different as compared with healthy subjects.
