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

This study was designed to investigate the function of outer hair cells and medial olivocochlear efferents in type II diabetes mellitus (DM). Materials and methods: There were 50 patients with type II DM and 51 age- and sex-matched healthy controls included in the study. Both groups were compared in terms of transient evoked otoacoustic emissions (TEOAEs), distortion product otoacoustic emissions (DPOAEs), and contralateral suppression of TEOAE. Results: Pure tone thresholds of the patients with type II DM were significantly higher than in the controls (P < 0.05). The TEOAE amplitudes at 1 kHz and at 1.5, 2, 3, 4, and 6 kHz signal-to-noise ratio amplitudes on DPOAE testing were significantly lower in the patients than controls (P < 0.05). There was no significant difference between the type II DM and control groups regarding contralateral suppression test results of TEOAEs. Conclusion: Type II DM seems to impact the auditory system at the cochlear level by affecting the functions of outer hair cells, and it results in elevation of the thresholds on audiometry and a decrease in the amplitudes of otoacoustic emissions.

To evaluate the role of computed tomography (CT) perfusion imaging in patients with hepatocellular carcinoma (HCC). Materials and methods: Seventeen patients (9 men, 8 women) with newly diagnosed HCC, proven by biopsy, were evaluated with 256-slice helical CT. Perfusion parameters of blood flow (BF), blood volume (BV), arterial perfusion (AP), portal perfusion (PP), and hepatic perfusion index (HPI) were calculated in the normal liver parenchyma and HCC samples. Results: A total of 21 histologically proven HCC lesions were evaluated from CT perfusion images. BF, BV, AP, and HPI values were shown to be significantly higher (P < 0.05) in the HCC lesions than in the normal liver parenchyma. Conversely, PP values were found to be significantly lower (P < 0.05) in HCC relative to liver parenchyma. Conclusion: CT perfusion imaging has the ability to evaluate tumor assessment, characterization, and neoangiogenesis in HCC.

To evaluate the effects of anti-tumor necrosis factor-alpha (TNF-\alpha) therapy on the frequency of varicocele in patients with ankylosing spondylitis (AS) using color Doppler ultrasound. Materials and methods: The patients were divided into 2 groups: patients with AS who were on anti-TNF-\alpha treatment and patients with AS who were not regularly taking any antiinflammatory drugs. Thirty-one healthy volunteers were included as controls. Results: Left-sided varicocele was determined in 14 patients of Group 1 (44%), 10 patients of Group 2 (33%), and 7 of the controls (23%). There was a statistically significant difference only between Group 1 and controls (P = …

To establish age- and sex-specific reference intervals for essential amino acids in a healthy Turkish pediatric population. Materials and methods: A total of 945 clinically healthy children (531 boys and 414 girls, ranging in age from birth to 14 years) were enrolled. Plasma and urine amino acids' concentrations were measured by high-performance liquid chromatography. Results: Concentrations of essential amino acids in plasma were higher in girls than in boys in the age groups of 0-1 months and 7-14 years; however, there was no difference in the other age groups. Concentrations of essential amino acids in urine were higher in girls …
