Does someone have a protocol for glucose uptake experiments in vivo?

I am planning to run a glucose uptake experiment in mice (In vivo). I would like to inject H3-2DG and just measure the percent of H3 in different tissues. No clamp experiment, but I was thinkMing...

What are the methods to identify qualitatively, and quantitatively, the bacterial community of samples?

I do not wish to use the time-consuming cloning/sequencing methods or costly 454 GS platform. The Ion Torrent PGM technology seems to offer modest set-up and running costs. What are your experiences?

Should a new medical device be evaluated on its own (such as a drug) or integrated with its end-user and its environment?

The diversity of medical devices, their increasing complexity, as well as the development of devices for personal use have increased the risk associated with misuse. The use made by "operators",...

For acid treated montmorillonite clays what will be the result of surface area?

The organo montmorillonite nanoclays modified with octadecylamine were used for the experiment. After acid treatment, the surface area will be increase. However, in my experiment, the surface area...

What could be the reason for XRD pattern starting from very high counts/intensity at 3 degree 2 theta?

I am working on XRD analysis of the clay minerals from the sea sediments. My XRD pattern shows very high counts at the start of the XRD pattern (3 degree 2 theta) which is very unusual. The counts...

Is it possible to prepare clay minerals by mixing pure oxides of required elements? What would be theoretical difficulties with it?

Practically this is not at all necessary. But theoretically, would hydrous/hydrothermal synthesis be enough (like mix 1 mole alumina gel and 4 mole silica gel and gently heat) or would it require...
