Long lived BSA Au clusters as a time gated intensity imaging probe.

The work presented here reports the use of long lifetime (>1 µs) BSA Au clusters as a cellular/tissue, time gated, intensity imaging probe. By collecting the emission signal 50 ns post excitation, one can off-gate the intense auto-fluorescence background, thereby greatly enhancing the clarity/specificity in fluorescence imaging.

Secondary involvement of femur in carcinoma of gall bladder.

A case with bony metastasis to right femur from a primary carcinoma of gall bladder is described. This is probably one of the most rare presentation of the disease without producing any signs or symptoms suggestive of a primary pathology in gall bladder.
