Oxidative Stress Upregulates the Transcription of Genes Involved in Thiamine Metabolism

Thiamine is a major vitamin that acts as a cofactor in energy metabolism in all organisms, as well as in lipid and amino acid metabolisms, and is associated with many diseases. It is known that glucose starvation decreases the intracellular thiamine pool while increasing oxidative stress tolerance. Earlier, in whole genome analysis, we detected major differences in the expression of genes related to thiamine pathway against oxidative stress in Schizosaccharomyces pombe. We investigated the effects of oxidative stress and glucose repression to thiamine pathway in S. pombe by comparing some genes encoding key enzymes of each related pathway at the transcription level. In the present study, we found that the expression of genes related to thiamine biosynthesis and transport (thi2, thi3, and pho1) increased in wild type and ird11 cells grown in thiamine-rich media under oxidative stress induced by H2O2. Based on our findings, we suggested that there might be an important effect of oxidative stress on thiamine biosynthesis and transport

Comparison of vitamin B12, vitamin D and folic acid blood levels in patients with schizophrenia, drug addiction and controls

Schizophrenia (SCH) and drug addiction are chronic disorders that are frequently accompanied by physical diseases, poor nutrition and reduced self-care, all of which are likely to result in vitamin deficiencies. The objective of this study was to compare vitamin levels in SCH patients, substance use disorder (SUD) patients and healthy controls (HCs). The study included 189 SCH patients, 119 SUD patients and 109 HCs. Information on vitamin B12, folic acid and vitamin D levels were retrieved from the hospital's database, and mean values and deficiency/insufficiency were evaluated. Vitamin D deficiency (<30 ng/ml) was more common in the SCH group than in the SUD and HC groups (88.4%. 74.8% and 86.4%. respectively). Although there were no significant differences in folic acid deficiency (<3.0 ng/ml) in the SUD and SCH groups (15.1% and 8.5%, respectively), the incidence of folic acid deficiency was significantly higher in both groups as compared with that in the HC group (5.8%). Significantly higher numbers of patients in the SCH group than in the SUD group had vitamin B12 deficiency (45.5% vs. 28.3%). The prevalence of vitamin B12 deficiency in the SUD group was significantly higher than that the HC group (28.3% vs.11.5%). As compared with the HC group, vitamin D and B12 levels were significantly lower in SCH group, and folic acid and B12 levels were significantly lower in the SUD group. Several vitamin deficiencies appear to be common in both SCH and SUD. Possible reasons should be investigated. (C) 2019 Elsevier Ltd. All rights reserved

Frequency and duration of smoking scenes in Turkish movies

BACKGROUND: Comprehensive tobacco control law in Turkey bans advertisement, promotion of tobacco products and sponsorship by the tobacco industry. Advertisement of tobacco products was banned on television, billboards and press media, but not on movie films. METHODS: To evaluate the frequency and duration of smoking in the movies, 60 most watched Turkish films which were on the vision during the second half of 2016 were determined for this descriptive study. Two young males having a university degree were trained on the aim and methodology of the study. Then the two observers viewed the films independently and recorded smoking scenes or direct appearance of tobacco products on a standard form. RESULTS: There were tobacco products or smoking views in 36 (60%) out of total 60 movies. In these movies there were 4.75 times tobacco occurrences as an average (median 3). Average duration of smoking occurrences was almost 3.5 min (198 s). Smokers were mostly main characters and smoking occurrences were mostly in exciting or romantic atmosphere, which are attractive for young people. DISCUSSION: In the light of Framework Convention on Tobacco Control (Article 13), smoking scenes in movies are considered as kind of tobacco advertisement and promotion, which influences smoking behavior particularly the young people. Therefore, control and prevention of smoking occurrences in movies are important for the protection of children and young people to start smoking. Some health warnings and anti-tobacco messages may be placed in the movies, to reduce tobacco views in the movies

Impact of fingolimod on CD4+T cell subset and cytokine profile of relapsing remitting multiple sclerosis patients

Fingolimod inhibits the egress of lymphocytes from lymphatic tissues and also directly affects their functions by modulation of the sphingosine-1 -phosphate receptor 1 (S1P1). Our aim was to evaluate the impact of fingolimod on diverse CD4+ T cell subsets, and cytokines

Definitive Chemoradiotherapy In Stage Iii Nonsmall Cell Lung Cancer: Turkey Experience

Aim: Concurrent chemoradiotherapy (CRT) is the standard therapy for patients with unresectable Stage III nonsmall cell lung cancer (NSCLC). The aim of this study was to assess the efficacy and safety of concurrent CRT in unresectable Stage III NSCLC in Turkey. Patients and Methods: The study included 82 patients with histologically proven unresectable Stage III NSCLC, Eastern Cooperative Oncology Group performance status 0-1, who received concurrent CRT in two different referral centers. Treatment consisted of two cycles of cisplatin at 50 mg/m(2) on days 1, 8, 29, and 36 and etoposide 50 mg/m(2) between days 1 and 5, 29-33 and concurrent radiotherapy administered once daily, 1.8-2.0 Gy per fraction, at a total dose of 60-66 Gy. Results: The stages of the patients were Stage IIIA in 39 (47.5%) and IIIB in 43 (52.5%) patients. Complete and partial responses were achieved in 15 (18.2%) and 31 (37.8%) of the patients, respectively. Twenty-eight (34.2%) patients had stable disease and 8 (9.8) had progressive disease. Forty-one (50%) patients recurred during follow-up. The primary site of recurrence was as distant metastasis in 19 (23.2%) patients. Median overall survival (OS) was 20 months (95% confidence interval; 12.9-27.09 months), 3 and 4 years survivals were 27.9% and 20.9%, respectively. Median progression-free survival (PFS) was 9 months, 3 and 4 years PFSs were 20.1% and 16.1%. Myelosuppression was the most common toxicity. In 15 (19.2%) patients grade 2-3 lung toxicity and in seven (8.5%) patients' grade 2-3 dysphagia were reported. Conclusion: Concurrent CRT with cisplatin and etoposide schedule is a well-tolerated regimen with acceptable toxicity profile and survival rates in patients with unresectable Stage IIIA/IIIB NSCLC. Median survival and OS results were consistent with the literature.WoSScopu
