OBJECTIVE To compare serum cytokine levels in patients with hyperemesis gravidarum with levels in healthy pregnant and nonpregnant women. DESIGN Case-control study. SETTING Clinical and academic research center. PATIENT(S) Thirty women with hyperemesis gravidarum, 30 healthy women in the first trimester of pregnancy, and 30 healthy nonpregnant women.(More)
Higher technetium-99m methoxyisobutylisonitrile (MIBI) uptake in non-small cell lung cancer (NSCLC) has been reported to be associated with a positive response to chemotherapy. It has previously been found that in tumour cells, P-glycoprotein (Pgp) expression is of importance for tracer uptake. However, some studies have indicated that Pgp expression does(More)
BACKGROUND/AIMS We aimed to assess the effect of azathioprine on mucosal healing in patients with inflammatory bowel diseases (IBD). Artificial neural networks were applied to IBD data for predicting mucosal remission. MATERIALS AND METHODS Two thousand seven hundred patients with IBD were evaluated. According to the computer-based study, data of 129(More)
OBJECTIVE We evaluated tumor necrosis factor-alpha (TNF-alpha) and interleukin-2 (IL-2) receptor levels in patients with threatened abortion and compared the levels with normal and pathologic pregnancies. DESIGN A prospective, nonrandomized, case-control study. SETTING Academic research setting. PATIENT(S) Twenty-two patients with threatened abortion,(More)
Prediction and evaluation of the response to chemotherapy (CTx) are important for the correct and cost-effective treatment of patients with primary lung cancer. Although fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) is accepted as the most useful and accurate nuclear medicine technique for this purpose, its expense and limited(More)
OBJECTIVE To evaluate maternal serum tumor necrosis factor-alpha (TNF alpha) levels in patients with preterm labor without clinical signs of chorioamnionitis and to compare these with levels in nonlaboring controls. STUDY DESIGN The study group consisted of 44 patients with a singleton pregnancy admitted to our department with the diagnosis of preterm(More)
The thickening of alveolar basement membrane is found in autopsies, along with microvascular pathologies, in Type 1 and 2 diabetes mellitus (DM). To detect the function and permeability of alveolar basement membrane, carbon monoxide diffusion capacity (DLCO) and technetium 99m-diethyltriaminepentaaceticacid ((99m)Tc-DTPA) aerosol scintigraphy methods can be(More)
A patient with suspicion of a neuroendocrine tumor of the pancreas underwent a somatostatin receptor scintigraphy using 111In-Pentetreotide. 111In-pentetreotide scintigraphy showed discrete uptake of the radiotracer in the head of the pancreas and focal uptake in the right upper thyroid lobe. Tracer uptake in the 24h planar image was higher compared to the(More)
Liver ischaemia may lead to parenchymal damage depending on the duration of the ischaemia. Dimethylsulphoxide (DMSO), a well-known radical oxygen scavenger, is a protective agent against ischaemia/reperfusion injury. In this study we aimed to investigate the role of hepatobiliary scintigraphy (HBSc) in detecting the protective effect of DMSO. Eighteen(More)
Halothane and its metabolites cause liver damage by decreasing liver blood flow and generating free-radical species. Catechin suppresses lipid peroxidation and increases enzyme activity, therefore it seems to be capable of protecting liver parenchyma against the direct toxic effect of halothane. The aim of this study was to investigate the role of(More)
