Atrial natriuretic factor in Meriones unguiculatus, the Mongolian gerbil

The basis for the great osmoregulatory ability in Meriones unguiculatus, the Mongolian gerbil, has been studied previously, but as yet no clear mechanism has been determined. The present study investigated the level of cardiac atrial natriuretic factor (ANF) under high and low sodium stress. In addition, cardiac ANF values for the Mongolian gerbil were compared with another desert mammal (Mesocricetus auratus, the Syrian golden hamster) and a non-desert mammal, (Rattus norvegicus, the white rat). ANF was found to exist in the hear atria of the Mongolian gerbil at a level of 388±66 µg ANF/g tissue. High and low sodium stress did not have a significant effect on the cardiac level of ANF in the Mongolian gerbil. Finally, the Mongolian gerbil had cardiac ANF levels similar to the Syrian golden hamster but 3 to 4 times less than the white rat

Resilient Biosensing and Learning Circuits

This work can be split into three sections. The first is the development of two wearable EEG systems. These systems can be integrated into helmets for wearable use, and rely on direct (ohmic) connections to the scalp. The second section encompasses exploratory investigations into the use of flexible active ohmic electrodes and indirect (capacitive) con- nections to the body within the scope of biosensing. The third section involves the develop- ment of FPAA infrastructures for investigation into analog computing techniques. Related to biosensing, these systems could be used as early signal chain dimension reducers and anomaly classifiers.M.S
