Comparison of established systems for measuring the dustiness of powders with the UNC Dustiness Tester developed especially for pharmaceutical substances.

Four methods for evaluating the dustiness of powders have been compared. The relatively new UNC Dustiness Tester first described by Boundy et al. (2006) in the Annals of Occupational Hygiene, which was developed specifically for the measurement of hazardous and/or highly potent substances, a single-drop device, a rotating-drum method, and a continuous drop-down apparatus.

Expression of galectin-3 in pancreatic ductal adenocarcinoma.

Galectin-3 influences neoangiogenesis, tumor cell adhesion, and tumor-immune-escape mechanisms. Hence, the expression of galectin-3 in pancreatic ductal adenocarcinoma (PDAC) was evaluated. Galectin-3 expression in PDAC cell lines was proven by the presence of intracellular protein and by release into the supernatant.

Determining the dustiness of powders--a comparison of three measuring devices.

The dustiness of 12 test powders was determined using three different measuring methods. One of the methods, the continuous drop method, is a reference test method according to the EN 15051 'Workplace atmospheres--Measurement of the dustiness of bulk materials--Requirements and reference test methods'. A test of equivalence between the reference test method and the other two methods, the modified Heubach Dustmeter, a rotating drum method and the Palas Dustview, a single-drop method, has been carried out as provided in Annex D of the European standard.
