Studying slime.
Oestrogen receptor protein (ER) was detected in 9 of 11 samples of malignant breast tissue and 8 of 9 samples of normal breast tissue. Levels of cytosolic ER (ERJ) in malignant breast were 21-1102 fmol mgsoluble protein (Kd1.8x 10-9-3.1 x 10-8moll-1) and those of nucleosolic ER (ERj), 13-526fmolmg-' soluble protein (Kd 2.1 x 10-9-1.4 x 10 8mol '1). In normal breast tissue ERC levels were 33-640...
متن کاملThe hagfish slime gland: a model system for studying the biology of mucus.
The hagfish slime gland may provide a model system for studying certain aspects of the biology of mucus. Mucus is obtained in nonhydrated form by electrically stimulating the anesthetized hagfish and the secretions are stirred into ammonium sulfate. Centrifugation and filtration are than used to isolate the two major secretory products, mucous vesicles and threads. Specific advantages of the mo...
متن کاملExtinction, Slime, and Bottoms
Open access, freely available online T here is an old Chinese curse: 'May you live in interesting times.' According to those who know about such things, we live in a momentous time, the time of the Sixth Mass Extinction! But most of us do not feel at all cursed. Because, in fact, the Sixth is quite different to the previous Big Five—no-one would notice this one if we were not repeatedly reminde...
متن کاملSlime mould tactile sensor
Slime mould P. polycephalum is a single cells visible by unaided eye. The cells shows a wide spectrum of intelligent behaviour. By interpreting the behaviour in terms of computation one can make a slime mould based computing device. The Physarum computers are capable to solve a range of tasks of computational geometry, optimisation and logic. Physarum computers designed so far lack of localised...
متن کاملSlime mould electronic oscillators
We construct electronic oscillator from acellular slime mould Physarum polycephalum. The slime mould oscillator is made of two electrodes connected by a protoplasmic tube of the living slime mould. A protoplasmic tube has an average resistance of 3 MOhm. The tube’s resistance is changing over time due to peristaltic contractile activity of the tube. The resistance of the protoplasmic tube oscil...
