The effects of starter culture containing Lactobacillus sake, Pediococcus pentosaceus, Staphylococcus carnosus plus Staphylococcus xylosus on the formation of biogenic amines during ripening of Turkish soudjoucks were investigated. Determination of eight different biogenic amines was carried out by reverse-phase high performance liquid chromatography (HPLC)(More)
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease that leads to fixed narrowing of small airways and alveolar wall destruction (emphysema). This study was performed to test the association between MMP-7 (rs155668818) and MMP-12 (rs56184183) polymorphisms in the MMP-7 gene and COPD risk and its severity in the Turkish population.(More)
BACKGROUND Angiogenesis is the formation of new blood vessels from pre-existing vasculature. Many factors and substances may stimulate angiogenesis and exhibit proliferative effect. In this study, we aimed to investigate the angiogenic and proliferative effects of sodium nitrite. MATERIAL AND METHODS The angiogenic activity of sodium nitrite was examined in(More)
OBJECTIVE Electrical cardioversion (EC) is a short but painful procedure to restore sinus rhythm. The aim of this study is to compare the effect of fentanyl, remifentanil and alfentanil in association with propofol and midazolam for elective EC. PATIENTS AND METHODS Ninety-nine patients older than 18-years, American Society of Anesthesiologists I/II/III(More)
OBJECTIVE Pulmonary artery hypertension (PAH) is devastating disease that has very serious outcomes. Dysregulated angiogenesis is one of the main responsible courses in pathophysiology of disease. Our experimental research intends to find out and compare the angiogenic effects of medications used sildenafil, iloprost, and bosentan in the treatment of PAH.(More)
OBJECTIVE Opioid-induced hyperalgesia is well known complication of acute high dose and chronic opioid therapy. In this study, we evaluated development of opioid-induced hyperalgesia following intraoperative short-term use of µ-opioid agonist fentanyl after coronary artery bypass surgery. PATIENTS AND METHODS 100 patients undergoing elective coronary(More)
The objective of this clinical study was to compare conventional caries detection techniques, pen-type laser fluorescence device, and near-infrared light transillumination method in approximal dentin caries lesions. The study included 157 patients, aged 12–18, without any cavity in the posterior teeth. Two calibrated examiners carried out the assessments of(More)
OBJECTIVE Polidocanol is the most frequently used sclerosant for sclerotherapy all around the world. Our experimental research aims to find out the angiogenic effects of Polidocanol. MATERIALS AND METHODS Angiogenic activity of polidocanol was examined in vivo in the chick chorioallantoic membrane (CAM) model, cell viability assay (human umbilical vein(More)
