Resistin plays a role in the pathogenesis of coronary artery disease and is related to mortality and morbidity through a number of mechanisms. We hypothesize that plasma resistin levels are increased in the presence of ischemia, as measured by GATED single-photon emission computed tomography myocardial perfusion scintigraphy (SPECT MPS), in comparison with nonischemic subjects. Materials and methods: Fasting intravenous blood samples of patients were drawn before a stress test. An ELISA kit was used for the assays. All patients underwent a technetium 99m-sestamibi GATED SPECT MPS study with a 1-day stress-rest protocol. Images were analyzed visually and patients were assessed …

Folate And Homocysteine Metabolisms And Their Roles In The Biochemical Basis Of Neuropsychiatry, Alpaslan Coşar, Osman Meti̇n İpci̇oğlu, Ömer Özcan, Mustafa Gültepe Jan 2014

Folate And Homocysteine Metabolisms And Their Roles In The Biochemical Basis Of Neuropsychiatry, Alpaslan Coşar, Osman Meti̇n İpci̇oğlu, Ömer Özcan, Mustafa Gültepe

Turkish Journal of Medical Sciences

The term 'one-carbon metabolism' is commonly used to describe 3 separate metabolic processes: folate metabolism, the homocysteine remethylation cycle, and the transsulfuration pathway. Folate metabolism concerns the biochemical reactions in which endogenous and exogenous one-carbon units are transferred to tetrahydrofolates. The remethylation cycle is used for the synthesis of methionine from homocysteine with one-carbon units that come from folate. This methionine is then used for the synthesis of S-adenosyl methionine, which is a general donor of methyl groups for many biochemical reactions in the human body. In the transsulfuration pathway, some amino acids and polypeptides, such as cystathionine, cysteine, and …

Turkish Journal of Medical Sciences

Malnutrition is a common medical condition among intensive care unit patients. It should be monitored carefully, since early management of malnutrition can dramatically improve the medical condition of the patients. A general consideration of enteral feeding shows that it is much more useful than parenteral administration, because it is more physiological and poses a lower risk of hyperalimentation. Materials and methods: In this retrospective study, we scanned all files and personal information of patients hospitalized in intensive care units between 2009 and 2012 due to various medical conditions. We evaluated the nutritional status of patients with biochemical parameters that were …

To investigate the effect of ozone and/or taurine treatment comparatively on testicular damage due to ischemia/reperfusion (I/R) injury in an experimental torsion model in rats. Materials and methods: Adult Wistar rats with and without torsion/detorsion were used. In order to monitor the effect of ozone and/or taurine treatment on testicular damage due to I/R injury, following histopathological investigation apoptotic indexes were scored by TUNEL method. Moreover, tumor necrosis factor receptor 1 (TNFR1), caspase 3, caspase 8, endothelial nitric oxide synthase (eNOS), tumor necrosis factor alpha (TNF\alpha), and cytochrome C immunostainings were performed and the levels of malondialdehyde, glutathione peroxidase, superoxide …

Findings from clinical studies in postmenopausal women with late initiation of hormone replacement therapy (HRT) that test whether HRT protects cognitive functions in women are inconsistent. The aim of this study was to investigate the effects of HRT on brain metabolite ratios when initiated in the early postmenopausal period (critical window). Materials and methods: Proton magnetic resonance spectrometry (1H MRS) was performed in 4 brain regions of 47 healthy postmenopausal women (21 received HRT, 26 did not). The subjects were aged between 45 and 65 years. The duration of HRT ranged from 1 to 12 years (mean: 6.3 years). The …

Infertility is defined as the inability to conceive after at least 1 year of unprotected intercourse. In about one third of infertile couples, a male factor is the primary problem. Thus, the present study aimed to determine the most common risk factors for male infertility in Iranian men. Materials and methods: This case-control study included 268 men attending an infertility clinic in Shiraz, Iran. In this study, 161 fertile men were compared with 108 infertile ones regarding risk factors such as smoking habits, drug consumption, hernia, varicocele, job, and BMI. The data were analyzed using logistic regression analysis and t-test. …
