Abstract: The invention relates to a protective helmet, comprising an outer shell (1) for distributing impact forces and an antenna (2) for transferring a radio signal, which antenna is arranged at least partially inside the outer shell (1). The outer shell (1) consists of a main material in a main region (5). The protective helmet is characterized in that the outer shell (1) consists of a cut-out material in a cut-out region (6), the cut-out material having a lesser damping effect on the radio signal in comparison with the main material. The invention further relates to a method for producing a protective helmet.

Abstract: The invention relates to an outer shell for a safety helmet (1), in particular for a motorcycle safety helmet, for distributing impact forces, said outer shell having an outer shell material (2). The outer shell is characterized in that, on a side (3) having the outer shell material (2) of the outer shell, the outer shell has a cover (4) having the outer shell material (2) in order to hold an antenna (5) between the cover (4) and the side (3). The invention further relates to a safety helmet (1) having such an outer shell and to a method for producing such an outer shell.

Abstract: A method for screening a test compound for activity in modulating the activity of the chloride channel ClC-7 either directly or by modulating the subcellular localization of Ostm1 comprises determining whether test compound inhibits the binding of Ostm1 to ClC-7. Compounds active in the screen are candidates for use in treating bone resorption conditions such as Osteoporosis by modulating the activity of osteoclasts.
