BACKGROUND The coexistence of Cd2+ and Zn2+ ions in nature has a significant influence on their environmental behaviors in soils and bioavailability for plants. While many studies have been done on the mutual toxicity of Cd2+ and Zn2+, few studies can be found in the literature focused on the interaction of Cd2+ and Zn2+ on soil clay fractions especially in terms of energy relationship. RESUL...
Recent data suggest that mast cells (MCs) in patients with systemic mastocytosis or mast cell leukemia express a CD2-reactive antigen. To explore the biochemical nature and function of this antigen, primary MCs as well as the MC line HMC-1 derived from a patient with mast cell leukemia were examined. Northern blot experiments revealed expression of CD2 messenger RNA in HMC-1, whereas primary no...
Heavy metals in the environment cause adverse effects on living organisms. Agro-wastes have potential to remove heavy from aqueous solutions. In this study, orange peel cellulose (OPC) beads were utilized as adsorbents wastewater. The surface of adsorbent was studied by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy coupled with energy dispersive x-ray (SEM-EDS...
This paper examined the competitive removal of metal ions from quaternary aqueous solutions containing Ni2+, Mn2+, Cr6+, and Cd2+ using adsorption on both acid-modified unmodified activated carbon. Activated carbon (AC) was oxidized with nitric acid, in granular (AGC) powder (APC) forms, tested for an solution. Surface oxidation led to a reduction BET surface area HK pore width increase intensi...
Rice plants accumulate cadmium (Cd2+) within the grain, increasing the danger of human exposure. Natural materials have been used in soil remediation, but few studies have examined the risks (based on the bioavailability of these metals to plants) of using these materials, so the practice remains controversial. In the present study, we evaluated the effectiveness of biochar produced from sugarc...
CD2, a cell surface glycoprotein expressed on T cells and natural killer cells, can couple to signaling pathways that result in T cell proliferation. An Src-like protein tyrosine kinase, p50 ok, coprecipitates with CD2, and perturbation of CD2 by monoclonal antibodies results in an increase in the activity of p56 kk, suggesting that an interaction with p56 l~k contributes to CD2mediated signali...
BACKGROUND Several heavy metals have been shown to have toxic effects on the peripheral and central auditory system. Cadmium (Cd2+) is an environmental contaminant showing a variety of adverse effects. Given the current rate of release into the environment, the amount of Cd2+ present in the human body and the incidence of Cd2+-related diseases are expected to increase. OBJECTIVE The overall a...
