Validating sweat ammonia as physiological parameter for wearable devices in sports science.

The measurement of physiological parameters in sweat has long been assumed to offer a non-invasive alternative to conventional blood testing. Recently, advances in sensor technology enable the production of printed sweat sensors applicable for the use in wearable devices. However, the remaining challenge is the determination of the physiological correlation between blood and sweat components.

[The thrombolytic treatment of acute and subacute recurrent pulmonary embolism with recombinant tissue plasminogen activator].

Thrombolytic treatment with recombinant tissue plasminogen activator (rt-PA) at a dosage of 40-150 mg was given to five patients with acute and five with recurrent pulmonary emboli (three women and seven men; mean age 54 [30-78] years). Mean pulmonary artery pressure fell from 29 +/- 7 mm Hg before to 20 +/- 5 mm Hg after treatment (P = 0.001), and in recurrent emboli from 47 +/- 19 to 18 +/- 10 mm Hg (P = 0.

Studies on dermographometry in atopic eczema.

The usual method of investigating dermatographism (D), which is typically white in atopic eczema (AE), allows only a qualitative rating. To allow reproducible quantification of D we have developed an easily usable device termed Dermography. This can be fitted with one to three blunt tapered metal bars of different weight applying a constant stretching pressure over the whole skin area to be examined with different pressures at isolated lines.
