The interaction between isatin-β-thiosemicarbazone (IBT) and calf thymus DNA (CT-DNA) was investigated in physiological buffer (pH 7.4) using Neutral Red (NR) dye as a spectral probe by UV–Vis absorption and fluorescence spectroscopy, as well as viscosity measurements. The IBT is stabilized by intercalation in the DNA ( K [IBT –DNA] =1.03×105 M−1), and displaces the NR dye from the NR–DNA comple...

For liver metastases (LM), image guided percutaneous ablative procedures such as radiofrequency ablation (RFA), laser induced thermal therapy (LITT) and trans-arterial chemo-embolisation (TACE) are increasingly being used because they are relatively safer, less invasive and equally effective. CT scan guided interstitial brachytherapy (IBT) with a single large dose of radiation by high dose rate...

Recent versions of international high-stakes tests like TOEFL and IELTS have made use of integrated tasks in addition to the traditional independent tasks in a claim to provide a more realistic estimation of the test takers’ language abilities. The present study aimed to investigate how test takers’ performance may differ on such tasks. As such, the test takers’ performance was compared on IELT...

BACKGROUND Interferon-based therapy (IBT) has been the standard of care for hepatitis C virus (HCV) infection. However, conflicting results exist regarding the effects of IBT on risk of developing hepatocellular carcinoma (HCC) and cirrhosis-associated complications, and most included highly selected patients. METHODS This 8-year cohort study was based on the Longitudinal Health Insurance Dat...

Despite the role writing plays in learning a foreign language, many students do not show much interest in taking an active part in writing classes (Myint, 1997). Thus different activities have been proposed to motivate students to write one of which is dialogue journal writing, and the present work tries to investigate the possible effect(s) of such activity on writing ability of a group of Eng...

BACKGROUND We evaluated the long-term outcome in patients harboring intracranial ependymomas treated with interstitial brachytherapy (IBT). METHODS Twenty-one patients (M/F = 9/12; median age: 29 years; range: 8-70 years), diagnosed with intracranial ependymoma (1 WHO I, 11 WHO II, 9 WHO III) were treated with IBT using stereotactically implanted (125)Iodine seeds between 1987 and 2010, eithe...

PURPOSE Peri-urethral cancer (PUC) in females is a rare malignancy. Surgery is not usually contemplated due to associated morbidity. Radiation therapy (RT) can be employed in the form of interstitial brachytherapy (IBT) alone for early lesions, and external beam radiation therapy (EBRT) with or without IBT for advanced lesions. We report our first experience in the literature to evaluate the ro...

Fourteen Trichoderma isolates were evaluated for their tolerance to two heavy metals, nickel and cadmium. Three isolates, MT-4, UBT-18, and IBT-I, showed high levels of nickel tolerance, whereas MT-4, UBT-18, and IBT-II showed better tolerance of cadmium than the other isolates. Under nickel stress, biomass production increased up to a Ni concentration of 60ppm in all strains but then decreased...
