The Porcupine Seabight Challenger Mound is the first carbonate mound to be drilled (approximately 270 m) and analyzed in detail microbiologically and biogeochemically. Two mound sites and a non-mound Reference site were analyzed with a range of molecular techniques [catalyzed reporter deposition-fluorescence in situ hybridization (CARD-FISH), quantitative PCR (16S rRNA and functional genes, dsr...

The presence of members of the family Helicobacteraceae in the colon of children was investigated using PCR, denaturing gradient gel electrophoresis, and fluorescent in situ hybridization. The rate of detection of species belonging to the Helicobacteraceae family in children with inflammatory bowel disease (92%) and irritable bowel syndrome (100%) was found to be significantly higher than that ...

The increasing problem of antibiotic resistance in common pathogenic bacteria and the concern about the spreading of antibiotics in the environment bring the need to find new methods to control fish pathogens. Phage therapy represents a potential alternative to antibiotics, but its use in aquaculture requires a detailed understanding of bacterial communities, namely of fish pathogenic bacteria....

Hydrogels In article number 2008793, Won Jong Kim and co-workers introduce an injectable in situ polymeric aggregate-embodied hybrid hydrogel (M-NO gel) to achieve nitric oxide (NO)-scavenging sequential drug-release for the combinatorial treatment of rheumatoid arthritis. This novel M-NO gel platform incorporated with a “clickable” NO-cleavable crosslinker is expected prove guideline various N...

سلنیوم به عنوان یک عنصر ضروری، نقش ویژه ای در رژیم غذایی انسان دارد. مقدار مورد نیاز یا سمیت سلنیوم به غلظت و فرم شیمیایی این عنصر بستگی دارد. بنابراین گونه شناسی و اندازه گیری مقادیر بسیار جزئی سلنیوم در ماتریس های مختلف امر مهمی می باشد. در این مطالعه سه روش مختلف برای اندازه گیری سلنیوم(iv) پیشنهاد شده است.در روش اول الکترود لایه نشانی شده با فیلم بیسموت/جیوه، تحت شرایط مدار باز و تکنیک ولتا...
