It is known that Steatoda (Lityphantes) paykulliana and Latrodectus mactans tredecimguttatus spider venoms are toxic to mammals and insects. These venoms act presynaptically eliciting massive release of transmitters. They also form channels in bilayer lipid membranes (BLM) that are selective for cations. Venoms of both spider species were fractionated by(More)
Membrane proteins have been isolated from neuromuscular synapses of the crab Potamon transcaspicum using a specific blocker of glutamatergic synapses, the neurotoxin of the spider Argiope lobata. These membrane components have been shown to induce glutamate-sensitive conductance in bilayer lipid membranes (BLM) in the presence of sodium ions. As an agent(More)
The changes of structural and photoluminescence (PL) characteristics of MBE-grown CdZnSe/ZnSe single quantum well (QW) structures caused by Cd/Zn interdiffusion were studied by high-resolution X-ray diffraction (HRXRD) and low-temperature PL methods. The PL investigations showed that the increase of Cd content in the QW resulted in the increase of the depth(More)

An electron microprobe study has been carried out on platinum-group minerals, accessory phases, and chromite in several chromite deposits of the Alapaevsk ophiolite (Central Urals, Russia) namely the Bakanov Kluch, Kurmanovskoe, Lesnoe, 3-d Podyony Rudnik, Bol'shaya Kruglyshka, and Krest deposits. These deposits occur in partially to totally serpentinized(More)
