1. Application of Nickel Ferrite Nanoparticles in Adsorption of Amoxicillin Antibiotic
According to the World Health Organization, amoxicillin (AMX) is the most widely consumed antibiotic in the world. Consequently, there is great interest in the development of new technologies that allow the removal of this type of contaminant, as exposure to antibiotic residues can cause a variety of adverse effects, such as toxicity and antimicrobial resist

2. APLICAÇÃO DE NANOPARTÍCULAS DE FERRO ZERO-VALENTE (nFeZ) NA REMEDIAÇÃO DE SOLOS E ÁGUAS SUBTERRÂNEAS CONTAMINADAS: UMA REVISÃO
The remediation of contaminated soil and water is a relevant topic, being the focus of intense research. The use of nanoparticles to degrade contaminants has been consolidated as a sustainable remediation technology, with promising results worldwide. In this scenario, the zero-valent iron nanoparticles (nZVI) which, due to their properties, prove to be an im

3. Evaluation of anemia after long-term treatment with imatinib in chronic myeloid leukemia patients in chronic phase
ABSTRACT Introduction: The incidence of grade 3-4 anemia was reported to be 3% with imatinib therapy for newly diagnosed chronic myeloid leukemia (CML) in the chronic phase (CP). However, there are few data regarding the causes and the development of anemia after long-term treatment. This study aimed to evaluate the incidence of anemia after at least two ye

4. Elemental Concentration and Sulfur Chemical Speciation in the Amazonian Plant Andira surinamensis Using Synchrotron Radiation Techniques (SR-XRF, XANES), RBS and WD-XRF
The inorganic composition of the bark and leaf of a plant from the Amazon rainforest, Andira surinamensis, was determined using two non-destructive, multi-element techniques: X-ray fluorescence (XRF) and Rutherford backscattering spectrometry (RBS). XRF measurements were made using both a conventional X-ray source and synchrotron radiation. It was observed t

5. Alcesefoliside protects against oxidative brain injury in rats
ABSTRACT This study investigated the possible antioxidant and neuroprotective effects of alcesefoliside, isolated from Astragalus monspessulanus L., Fabaceae, against carbon tetrachloride (CCl4)-induced brain injury in Wistar rats. Iron sulphate/ascorbic acid lipid peroxidation was induced in rat brain microsomes and pre-incubated with alcesefoliside and sil

6. Biomonitors to evaluate the toxic potential of urban solid waste landfill leachate
Resumo O aumento acentuado da produção de resíduos sólidos urbanos (RSU) e o consequente acúmulo de lixiviado em aterros potencializam o risco de contaminação do meio ambiente. Biomonitores são utilizados para avaliação da toxicidade dos poluentes sobre os organismos vivos. Neste estudo, foram avaliados o potencial poluidor do lixiviado de RSU de u

7. Oxidative damage and photosynthetic impairment in tropical rice cultivars upon exposure to excess iron
ABSTRACT Iron plays a pivotal role in the redox reactions of photosynthesis and metabolic processes such as chlorophyll synthesis. Iron availability in waterlogged soils can reach toxic levels and promote oxidative stress. Fe toxicity is the most concerning of stresses for rice in many lowland environments around the world and may cause severe impairments in

8. Arsenic toxicity to cladocerans isolated and associated with iron: implications for aquatic environments
RESUMO Arsênio é um ametal amplamente distribuído na natureza e é distribuído e conhecido por sua elevada toxicidade. Muitos estudos tentaram elucidar o metabolismo do arsênio na célula e seu impacto para plantas, animais e à saúde humana. Em meio aquoso, arsênio inorgânico é mais comum e seu estado de oxidação (As III e As V) depende de condi�

9. The role of magnetic resonance imaging in the evaluation of transfusional iron overload in myelodysplastic syndromes
Myelodysplastic syndromes represent a group of heterogeneous hematopoietic neoplasms derived from an abnormal multipotent progenitor cell, characterized by a hyperproliferative bone marrow, dysplasia of the cellular hemopoietic elements and ineffective erythropoiesis. Anemia is a common finding in myelodysplastic syndrome patients, and blood transfusions are

10. Brazilian Thalassemia Association protocol for iron chelation therapy in patients under regular transfusion
In the absence of an iron chelating agent, patients with beta-thalassemia on regular transfusions present complications of transfusion-related iron overload. Without iron chelation therapy, heart disease is the major cause of death; however, hepatic and endocrine complications also occur. Currently there are three iron chelating agents available for continuo

12. Toxicidade de ferro e metabolismo antioxidativo em Eugenia uniflora L. / Iron toxicity and oxidative metabolism in Eugenia uniflora L.
O ferro é um micronutriente essencial para o crescimento e desenvolvimento das plantas. Quando em excesso, porém, pode induzir a produção e acúmulo de espécies ativas de oxigênio, causando estresse oxidativo levando a uma redução do crescimento e, portanto, diminuição na produtividade das plantas. O objetivo do trabalho foi, portanto, avaliar o ef
