Since there are no well-documented epidemiological studies on multiple sclerosis (MS) in South Africa, we devised a questionnaire to determine qualitative data. Responses were obtained from 430 patients: 91% had magnetic resonance imaging (MRI) scans, 64% had lumbar punctures and 49% had evoked potentials to establish the diagnosis of MS. A total of 71% of the respondents were aged 30 - 59 year...

OBJECTIVE To identify disparities-using recursive partitioning (RP)-in early survival for children with leukemias treated in Argentina, and to depict the main characteristics of the most vulnerable groups. METHODS This secondary data analysis evaluated 12-month survival (12-ms) in 3 987 children diagnosed between 2000 and 2008 with lymphoid leukemia (LL) and myeloid leukemia (ML) and register...

BACKGROUND Transvenous lead placement is the standard approach for left ventricular (LV) pacing in cardiac resynchronization therapy (CRT), while the open chest access epicardial lead placement is currently the most frequently used second choice. Our study aimed to compare the ventricular electromechanical synchronicity in patients with heart failure after CRT with these two different LV pacing...

Proinflammatory cytokines produced by Th-1 cells and cytokines with immunosuppressive properties play an important role in the pathogenesis of multiple sclerosis (MS). Glatiramer acetate (GA) is one of the most important immunomodulatory agents used in the therapy of MS. The mechanism of action of GA in MS is not yet fully explained. In our previous study we found the significant down-regulatio...

Cucumber is one of the main vegetables in Iranian food basket. A wide range of pesticides are used for crops protection during the cultivation of vegetables such as cucumber due to heavy pest infestation. Analysis of pesticide residues in food and other environmental commodities have become essential requirement for consumers, producers, and food quality control authorities. This study was aime...

OBJECTIVE The aim was to assess possible relationship between oral hygiene, salivary cariogenic microflora, buffer capacity, secretion rate and caries experience in 6 year olds and 12 year olds in Riga, and to evaluate these variables in relation to caries risk. MATERIALS AND METHODS 50 children aged 6 and 71 children aged 12 were examined clinically and by bitewing X-ray for caries diagnosis...

OBJECTIVE Combined sedation with propofol and benzodiazepines, known as balanced propofol sedation (BPS), was developed to increase patient comfort during endoscopy. However, the effects of BPS on P-wave dispersion (Pwd), QT interval, and corrected QT (QTc) interval after endoscopy have not been investigated. METHODS The study population consisted of 40 patients with BPS and 42 without sedati...

abstract   background: multiple sclerosis (ms) is the most common autoimmune disease of central nervous system with destruction of myelin sheath mediated by auto reactive cd4+ t lymphocytes. because of the possible role of epstein-barr virus in etiology of ms and t cells immune response, the aim of this study was to evaluate anti-epstein barr virus antibodies as a marker of reactivity and produ...

The lumen segment of cytochrome f consists of a small and a large domain. The role of the small domain in the biogenesis and stability of the cytochrome b(6)f complex and electron transfer through the cytochrome b(6)f complex was studied with a small domain deletion mutant in Chlamydomonas reinhardtii. The mutant is able to grow photoautotrophically but with a slower rate than the wild type str...
