Helicobacter breaks down junctions

and colleagues. Although the bacteria may do it to gain access to tasty chemicals that leak out, the results for humans may include stomach ulcers and gastric cancer. The link from cell junctions to stomach ailments may, say the researchers, lie in tissue repair. Injury to the stomach triggers cell division and migration to plug the gap. The chiefs in charge of these processes may well lie in c...

How superhydrophobicity breaks down.

A droplet deposited or impacting on a superhydrophobic surface rolls off easily, leaving the surface dry and clean. This remarkable property is due to a surface structure that favors the entrainment of air cushions beneath the drop, leading to the so-called Cassie state. The Cassie state competes with the Wenzel (impaled) state, in which the liquid fully wets the substrate. To use superhydropho...

Breaks in Thermal Spraying Processes

The detection of structural changes in time series from industrial processes monitoring is of great interest. We investigate the limits and possibilities of two recently developed methods, one for the off-line detection of changed volatilities [Wied et al., 2011] and one for the on-line detection of changes in the course of the time series [Borowski and Fried, 2011]. The investigation is carrie...

Autoimmunity: When self-tolerance breaks down

The spontaneous development of destructive polyarthritis in mice transgenic for an autoreactive T-cell receptor supports the notion that a failure of T-cell self-tolerance can lead to similar diseases in humans, and sheds new light on the role of peripheral tolerance in the avoidance of such pathological immune responses.
