On the Antigens of Red Blood Corpuscles
1. Flocculation reactions of anti-erythrocyte sera on emulsions of alcoholic extract of blood are described. 2. The reactions are markedly species-specific. 3. Besides the homologous reactions certain others-"heterogenetic"" ones-have been observed, and in this way the existence of new examples of heterogenetic antibodies has been demonstrated. 4. Group-specific substances can be extracted from...
متن کاملElectric Impedance of Injured and Sensitized Red Blood Corpuscles
On the basis of previous work on the electrical properties of hemolyzed red cells, it might be supposed that the variation of the capacity with frequency at low frequencies is an indication of membrane permeability. To test this, rabbit red cells were subjected to treatment with lecithin, tannic acid, glucose, saponin, amboceptor, and colloidal silicic acid, each in sub-lytic doses. No change i...
متن کاملInfrared-red Cores in Nearby Elliptical Galaxies
We present the Spitzer Space Telescope Infrared Array Camera (IRAC) observations for a sample of local elliptical galaxies to study later stages of AGN activities. A sample of 36 elliptical galaxies is selected from the Palomar spectroscopic survey. We detect nuclear non-stellar infrared emission in 9 of them. There is unambiguous evidence of circumnuclear dust in these 9 galaxies in their opti...
متن کاملIs AGN feedback necessary to form red elliptical galaxies ?
We have used the smoothed particle hydrodynamics (SPH) code GADGET-2 to simulate the formation of an elliptical galaxy in a group-size cosmological dark matter halo with mass Mhalo ≃ 3× 10 12 h −1 M⊙ at z = 0. The use of a stellar population synthesis model has allowed us to compute magnitudes, colours and surface brightness profiles. We have included a model to follow the growth of a central b...
متن کاملTHE FINE STRUCTURE OF MEISSNER's TOUCH CORPUSCLES OF HUMAN FINGERS
Thin slices of the finger pads of six individuals were fixed in buffered 1 per cent osmic acid, embedded in deaerated, nitrogenated methacrylate, and cut into thin sections for electron microscopic study. Before embedding, the slices were trimmed so as to include several digital tactile corpuscles. Some thin sections were stained in 10 per cent aqueous phosphotungstic acid solution. The princip...
