A two-photon "turn-on" fluorescent probe based on carbon nanodots for imaging and selective biosensing of hydrogen sulfide in live cells and tissues. Analyst 2014 Feb 27. Abstract: Determination of hydrogen sulfide (H2S) in live cells and tissues is still a challenge for evaluating the key roles that H2S plays in physiological and pathologi...

Live cell imaging is an essential approach for studying the structure, dynamics, and functions of cells in a living plant under normal or stressed growth conditions. The tiny flowering plant, Arabidopsis thaliana, provides an ideal system to apply various live microscopy techniques. Its small size allows fluorescent light to penetrate the tissues, and its plantlets contain different cell types ...

myiasis is the invasion of body tissues of humans and animals by the larvae of the diptera or two-winged flies. there are only sporadic reports in the literature concerning human ear myiasis. a 62-year-old bedridden woman in an intensive care unit was examined because of her intense swollen and erythematous right ear. physical examination revealed 80 live larvae (maggots) in the posterior part ...

Direct and quick molecular analysis of live plant single cells viewed under a video-microscope has been developed in their intact undamaged environment using nano-electrospray tip and mass spectrometers. This method has been successful in identifying specific molecules in plant live single-cell analysis by mass spectrometry, and opens the possibility to compare different cell types from differe...

Live-cell imaging offers the power of capturing the dynamics of biological action in live cells and in real time, something not previously available with biochemical approaches. Microscopy has progressed and static morphological observation can now be complemented by the ability to monitor dynamic cellular activities in living tissues with sub-micrometer resolution in real time. This offers val...

in order to investigate the microbiological safety of sanitary tissues made of recycled scrap papers in iran, random samples were taken for one year with the cooperation of the iranian standard and industrial research institute (karaj unit), of 44 types of sanitary tissues, two samples of each type including tissues, toilet papers and dippers as well as a control sample and their probable conta...
