Evaluation of cell membrane integrity as a potential antimicrobial
Evaluation of cell membrane integrity as a potential antimicrobial

... These results show that the RhPV 59 IRES functions efficiently in Sf 21 cells and in Sf 21 lysates; the RhPV 59 IRES also functions well in a Drosophila lysate (Woolaway et al., 2001). In contrast, the EMCV IRES is inactive in each of these systems (Finkelstein et al., 1999; Woolaway et al., 2001). ...

In the Rc3h1san/san mice the M199R is a hypomorphic rather than null mutation, since forced expression of Rc3h1M199R in san/san T cells induced an interm ...

LGN TC neuron in vitro causes a rapid depolarization that is initially associated with a profound reduction in input resistance RN (2) consisting of only two to four spikes but later with an increase in RN (3). In this cell, the depolarization brought about by Cch shifts the cell to just below the t ...

Organ-on-a-chip

An organ-on-a-chip (OC) is a multi-channel 3-D microfluidic cell culture chip that simulates the activities, mechanics and physiological response of entire organs and organ systems. It constitutes the subject matter of significant biomedical engineering research, more precisely in bio-MEMS. The convergence of labs-on-chips (LOCs) and cell biology has permitted the study of human physiology in an organ-specific context, introducing a novel model of in vitro multicellular human organisms. One day, they will perhaps abolish the need for animals in drug development and toxin testing.Although multiple publications claim to have translated organ functions onto this interface, the movement towards this microfluidic application is still in its infancy. Organs-on-chips will vary in design and approach between different researchers. As such, validation and optimization of these systems will likely be a long process. Organs that have been simulated by microfluidic devices include the heart, the lung, kidney, artery, bone, cartilage, skin and more.Nevertheless, building valid artificial organs requires not only a precise cellular manipulation, but a detailed understanding of the human body’s fundamental intricate response to any event. A common concern with organs-on-chips lies in the isolation of organs during testing. ""If you don’t use as close to the total physiological system that you can, you’re likely to run into troubles"" says William Haseltine, founder of Rockville, Maryland. Microfabrication, microelectronics and microfluidics offer the prospect of modeling sophisticated in vitro physiological responses under accurately simulated conditions.
