Analysis of Ammunition by X-Ray Fluorescence

X-ray fluorescence (XRF) has become a standard method of analysis over the past 25 years (Leyden, 1987) and has been used for many years in analysis ofammuni-tion(Brunelle etal., 1970). Aprincipal advantage of XRF analysis is that there is often no need to dissolve the sam-ple, toremove interferences, or other-wise toprepare the sample.

Review of Fluorescence Guided Surgery Systems: Identification

In recent years, there has been an explosion of interest in fluo-rescence-guided surgery, which has led to a steady demand for new commercially developed and approved fluorescence imag-ing devices. For the greatest clinical impact, an imaging system needs to provide a solution to the immediate clinical goal with

Leptin, Obesity, and Leptin Resistance: Where Are We 25 Years

During the last 25 years, leptin resistance, as observed in obesity, has been thought to be primarily due to the loss of the capacity of leptin to cross the BBB, chiefly by means of its specific transporter, but considering previously published data, the molecular mechanisms implicated in
