A recently developed method for enumerating aquatic viruses (Yo-Pro stained) was modified to reduce staining time and allow counting of fixed samples. Marine and freshwater virus samples to be enumerated were stained with the cyanine-based dye Yo-Pro-l by using microwave irradiation, which reduced incubation time from 48 h to 4 min. The modified method and the original protocol yielded similar ...

Abstract Biocompatible hydrogels of polyvinylpyrrolidone (PVP) with tannic acid (TA) in the weight ratios 1 : 0.70 (70 %)–1 0.60 (60 %) were prepared and loaded antifungal drug, nystatin (NYS). The hydrogel is expected to exhibit a two‐fold (anti‐bacterial anti‐fungal) characteristics. Infrared spectroscopy (IR), viscometry differential scanning calorimetry (DSC) used investigate interactions b...

BACKGROUND Colorectal cancer still has a high incidence and mortality. Although colonoscopy is considered as gold standard of colorectal cancer screening, there still exists an unsatisfactory level of adenomas missed in screening and surveillance colonoscopy. Furthermore, patients bear the burden of potentially unpleasant and painful examination and preparation procedures. METHOD A search of ...

OBJECTIVE To review the literature on the treatment of gastroesophageal reflux disease (GERD) with emphasis on proton pump inhibitors (PPIs), particularly on delayed-release esomeprazole, and to identify properties and adverse effects of PPIs observed in the treatment of GERD in children and adolescents. SOURCES Electronic search of PubMed/Medline and Cochrane Collaboration databases, and of ...

BACKGROUND It is believed that certain nutrients such as glutamine, arginine and omega-3 fatty acids may play a significant role in metabolic, inflammatory, and immune processes in acute pancreatitis. The present systematic review aimed to define whether the addition of these substances to enteral nutrition provides any clinical benefit over standard enteral formulas in patients with acute panc...

The induction of micronuclei was studied in mouse bone marrow treated or not with 5, 10 and 20 mg/kg b. wt. of Abana (a herbal preparation) before exposure to 0-3 Gy of γ-radiation. Whole-body irradiation of mice resulted in a dose-dependent increase in the frequency of micronuclei. Treatment of mice with various doses of Abana before exposure to different doses of γ-rays resulted in a signific...

After a 12 years’ observation in Vienna (VI), the superconducting gravimeter GWR C025 has been transferred in autumn 2007 to the new Conrad observatory (CO) 60 km SW of Vienna. It is one of few instruments which were operated at different stations. This aspect motivated a re-analysis of all calibration experiments performed so far in VI and CO, focused on the direct impact of drift effects and ...
