Biosorption characteristics of Cadmium from environment by one-year old seedlings of Acer velutinum

Background and Aims: Heavy metals are elements with high atomic weight and could be harmful for living organisms at higher concentrations. Cadmium is among these metals and may result in various health problems forhuman. The ability of Acer Velutinum in bioremediation of cadmium was considered in the present study.Materials and Methods: One-year old seedlings of Acer Velutinum were provided from Department of Natural Resources making arrangements well in advance. Cadmium chloride solutions were prepared with different concentrations of 0, 10, 20 and 40 mg/L and consequently were added into the soil. The seedlings were planted inpots and their aerial organs (stems and leaves) as well as their roots were separated three month after. The results were then analyzed using Danken and ANOVA tests.Results: The maximum amount of cadmium accumulation in aerial organs, root and soil was 9.67, 60.61 and 12.44 mg/kg, respectively. Similarly, the respective lowest level of cadmium accumulation in aerial organs, root and soil was 6.05, 2.3 and 0.1mg/kg. The least amount of aerial organs (4.45 g) and root (1.25 g) dry weights wereoccurred at 40 mg Ca/L, and the most values of respectively 9.02 and 3.95 g was observed at pristine control pot.Conclusion: Acer Velutinum species is considered as appropriate for bioremediation of soils contaminated by cadmium.Keywords: Cadmium, Adsorption, Heavy metals, Phytoremediation, Acer Velutinu

Zinc absorption in two-year old Poplar seedlings (Populus deltoids) in the environment

Background and Aims: Phytoremediation is the use of green plants to reduce contaminant levels such as heavy metals in the environment. Some plants can uptake and store (accumulate) environmental contaminants within their tissue and organs. Due to their sustainability in the environment, heavy metals are of particular significance. This study was, therefore, conducted to evaluate the phytoremediation potential of zinc by Populus deltoids.Materials and Methods: Biennial seedlings of populous deltoids were provided from plantations with arrangements made well in advance with the directors of the Department of Natural Resources. Zinc chloride solutions (0, 10, 20 and 40 mg /L) were prepared, added into the soil and the seedlings were thereafter placed in pots. The seedlings were grown for three months exposing to various zinc concentrations. Seedlings aerial organs (stems and leaves) and roots as well as the soil were sampled and analyzed using atomic absorption spectrometry. Analysis of variance (ANOVA) followed by Duncan’s multiple comparisons (P < 0.05) was performed to test the significance of treatment effects.Results: The highest level of Zn in aerial organs, root and the soil structure of Populous deltoids was 142.86, 85.94, 12.002 mg/kg, respectively. Similarly, the corresponding lowest level of Zn was 44.61, 21.20, and 0.124 mg/kg. The high-zinc (40 mg/L) treated plants showed the lowest levels of 4.14 and 1.03 g/L in aerial organs and root dry weights, respectively. The maximum values of 20.61 and 3.066 were also respectively determined at control experiments.Conclusions: The results suggest that Populous deltoids is an appropriate alternative for phytoremediation of zincpolluted soils

Bilateral Pulmonary Artery, Inferior Vena Cava, and Cardiac Echinococcosis: A Rare Presentation of Zoonotic Diseases

Introduction:Cystic hydatidosis is a zoonoticdisease thatis mostly observedin the Mediterranean region. This infectious disease may present throughdifferent manifestations that may delay the diagnosis and cause various complications for the patients. Most of the cases are usually diagnosed by imaging studies and the related management could be medical or surgical depending on the patient’s clinical condition and disease severity. Case presentation:In the present report, we present the case ofa 50-year-old female patient with a positive history of liver and splenichydatid cysts with hemoptysis and dyspnea. The diagnosis of pulmonary and cardiac involvement wasmade usingcomputed tomography angiography. Despite the immediate surgery, the patient died from hemorrhage after 3 days. Conclusion:Themanagement of pulmonary embolism due to Echinococcus highly depends on the clinical judgment and the outcomes are subject to the history and extent of the involvement

The Effectiveness of Meaning Training on Resiliency and Life Quality of Mothers with Children of Special Needs

The purpose of this study is to investigate the efficacy of meaning training on resiliency and improving the lifequality of mothers with children of special needs in Borazjan city. 222 mothers completed the questionnaire of World Health Organization Quality Of Life and Connor-Davidson Resilience Scale. Then 40 of these persons with one standard deviation below the mean score in both questionnaires were selected randomly for testing the hypothesis. These 40 persons were divided into two groups randomly (experimental and control group). At first the two groups took a pre-test, and then the experimental group received meaning training for 10 90-minute sessions. At the end, both groups took post-test simultaneously and after one month the follow-up test was done. The data of the study were analyzed by MANCOWA method. The results show that the meaning training has increased resiliency and improved the quality of life of the experimental group in comparison with the control group. A Follow-up study after one month shows the usefulness of meaning training on resiliency and quality of lif
