in this study, the aerial parts of pimpinella puberula were collected from ramhormoz and mashhad (khuzestan and khorasan provinces) at the vegetative, flowering and seeding stages. essential oils from the whole aerial parts as well as stem/leaf, inflorescence, unripe and ripe seeds, were isolated by hydro-distillation. the yields of essential oil obtained from the ramhormoz samples were 0.49%, ...
BACKGROUND For precise diagnosis of urinary tract infections (UTI), and selection of the appropriate prescriptions for their treatment, we explored a simple and rapid method of discriminating gram-positive and gram-negative bacteria in liquid samples. METHODOLOGY/PRINCIPAL FINDINGS We employed the NaOH-sodium dodecyl sulfate (SDS) solution conventionally used for plasmid extraction from Esche...
conclusions the ppi-g2 dendrimer with end amine groups exhibited a positive impact on the removal of dominant bacterial isolated strains. therefore, it is possible to use these nanodendrimers as a safe and effective material for water disinfection in the future. results the most important isolated bacteria were escherichia coli 37 (48.7%), klebsiella oxytoca 12 (15.8%), proteus mirabilis 3 (4%)...
