Every tenth lever-press of three morphine-dependent rhesus monkeys was reinforced with food. A red light, initially a neutral stimulus, was presented every third or fourth session for 5 min before and 5 min after an intravenous injection of nalorphine, a morphine antagonist that produces an immediate abstinence syndrome in morphine-dependent monkeys. After several pairings, conditioned suppress...

Macrophages play a critical role in iron homeostasis via their intimate association with developing and dying red cells. Central nurse macrophages promote erythropoiesis in the erythroblastic island niche. These macrophages make physical contact with erythroblasts, enabling signaling and the transfer of growth factors and possibly nutrients to the cells in their care. Human mature red cells hav...

The increased destruction of red cells after some corrective cardiac procedures has been recognized (Neill, Farman, Sigler, and Bahnsen, 1961; Sayed, Dacie, Handley, Lewis, and Cleland, 1961; Verdon, Forrester, and Crosby, 1963; Gehrmann and Loogen, 1964; Marsh, 1964; Reed and Dunn, 1964; Stevenson and Baker, 1964). Despite increased haemolysis, anaemia is not always present, since a normal bon...

A cellulose biopolymer was doped with Fe and Al forming a mesoporous composite. The composite showed excellent adsorption capacities of 117.86 mg g −1 95.62 for Reactive red 21 blue 19 respectively.

Herein, we present an original report on chlorine activation by ultrasound (US: 600 kHz, 120 W) for intensifying the sonochemical treatment of hazardous organic materials. The coupling US/chlorine produced synergy via involvement reactive species (RCSs: Cl•, ClO• and Cl2•−), resulting from sono-activation chlorine. degradation Allura Red AC (ARAC) textile dye, as a contaminant model, was drasti...

Azo dye Reactive Red 195 was selected for decolourization and degradation studies by Georgenia sp.CC-NMPT-T3. Optimization of parameters for dye decolourization was studied under static anoxic condition. Under optimized condition decolourization of Reactive Red 195 by Georgenia sp.CC-NMPT-T3 was found to be 95.93 % at 50 mg/L within five hours in static anoxic condition. The optimum pH and temp...

Currently used textile dyes are not highly toxic or carcinogenic, but the intense and persistent color of effluent is problematic. Of remediation processes investigated, adsorption process attractive, carbonaceous adsorbents (CAs) ideal for that purpose because their very high dye-binding capacity (DBC). In this review, potential biomass-based feedstocks to produce CAs application produced remo...
