1. Protective roles of Pyracantha fortuneana extract on acute renal toxicity induced by cadmium chloride in rats
Abstract Purpose: To investigate the protective roles of pyracantha fortune fruit extract (PFE) on acute renal toxicity induced by cadmium chloride (CdCl2) in rats. Methods: Rats were pretreated with PFE and consecutively injected with CdCl2 (6.5 mg/kg) for 5 days. Results: The concentration of Cd, kidney weight, malondialdehyde (MDA), and nitric oxide (N

2. Catalytic hydrogen generation from NaBH 4 /H 2 O system: effects of catalyst and promoters
Abstract A hydrogen generation system based on NaBH4 hydrolysis is affected by the nature of the catalyst and catalyst promoter. Various catalyst promoters such as Al2O3 nanoparticles, Al2O3 particles, ZrO2 sand, SiO2, MMT clay, CNT and zeolite are compared with respect to hydrogen generation (HG) and hydrogen generation rate (HGR). The highest HG and HGR ar

3. Adsorption of Transition Metal Chlorides by Silica with Grafted 1-n-Propyl-3-Methylimidazolium Chloride
Silica with grafted 1-n-propyl-3-methylimidazolium chloride was investigated as adsorbent for the removal of cobalt(II), copper(II), zinc(II), cadmium(II) and mercury(II) chlorides from alcoholic and aqueous solutions. The adsorption proceeds via the formation of metal-chloride anionic complexes detained near the grafted organic cations as counterions. This

4. Post-partum testosterone administration partially reverses the effects of perinatal cadmium exposure on sexual behavior in rats
This study investigated the effects of perinatal cadmium exposure on sexual behavior, organ weight, and testosterone levels in adult rats. We examined whether immediate postpartum testosterone administration is able to reverse the toxic effects of the metal. Forty pregnant Wistar rats were divided into three groups: 1) control, 2) 10 mg kg-1 cadmium chloride

5. Avaliação da qualidade da água de chuva e de um sistema filtro-vala-trincheira de infiltração no tratamento do escoamento superficial direto predial em escala real em São Carlos SP / Evaluation of rainfall water quality and a filter-swaleinfiltration trenches system in the treatment of the building direct runoff in real scale in são carlos sp
Several studies cite the pollution of stormwater as equivalent and sometimes even superior to those found in the sewers. According to this premise and thinking about environmental issues, especially in the contamination of groundwater and the spread of waterborne diseases, the quality of rainwater has become an important focus of study. This work concerns th

6. Stabilization of electric-arc furnace dust in concrete
Electric-arc furnace dust (EAFD) is a by-product of steel production and recycling. This fine-grained material contains high amounts of zinc and iron as well as significant amounts of potentially toxic elements such as lead, cadmium and chromium. Therefore, the treatment and stabilization of this industrial residue is necessary. Concrete is a well-known suit

7. Pré-concentração por extração em ponto nuvem para determinação de cádmio em amostras de bebidas por espectrometria de absorção atômica como forno tubular na chama e aerossol térmico / Preconcentration and Determination of Cadmium in Beverage Samples by Cloud Point Extraction and Thermospray Flame Furnace Atomic Absorption Spectrometry detection
In this work, it was evaluated extraction/preconcentration cloud point procedure for cadmium determination in soft drinks samples stored in polyethylene terephthalate (PET) packaging and detection by thermospray flame furnace atomic absorption spectrometry (TS -FF-AAS). For the cloud point preconcentration procedure were used Triton X-114 as surfactant, PAN

8. Estudos de alterações funcionais de macrofagos submetidos a hipoxia no modelo in vitro da leishmaniose / Studies of funcional alterations of macrophages submetted to hypoxia in ana in vitro model of leishmaniasis
Regions of low oxygen tension (hypoxia) are common features of inflamed/infected tissues. The analyses of cell phenotypic alterations by hypoxia are helpful for understanding of the pathological mechanisms and treatment resistance and for the development of cellular therapies. Macrophages, cells involved in the clearance of microorganisms from infected tissu

9. Effects of the association of cadmium chloride and guarana (Paullinia cupana) on the testis of wistar rats : morphometry, structure and ultrastructure / Efeitos da associação de cloreto de cadmio e guarana (Paullinia cupana) no testiculo de ratos Wistar : analise morfometrica, estrutural e ultraestrutural
Guaraná (Paullinia cupana Mart. var. Sorbilis) is a Brazilian plant, found in the Amazon basin. Previous studies have demonstrated the antioxidant properties of guaraná and its potential to neutralize free radicals. This plant is traditionally used for several therapeutic purposes and, recently, has been investigated to ascertain the potential of guaraná

10. Variação da qualidade da água do escoamento superficial de duas bacias de drenagem de Natal/RN - Brasil
The urban drainage is one of the powers of environmental sanitation and its scope is the quantitative and qualitative aspects. In decision making of managers and the engineering aspects of design are almost always taken into account only the quantitative aspects. However, the waters of the runoff have the highest concentrations of pollutants at the beginning

11. Recuperação de cádmio de baterias níquel-cádmio via extração seletiva com tributilfosfato (TBP)
This work describes a recovery process of cadmium from spent nickel-cadmium batteries by a new hydrometallurgical route based on the selective extraction in hydrochloric acid medium with tributylphosphate (TBP), alone or dissolved in kerosene. The best results were obtained when TBP concentration was at least 75 vol%. Nickel extraction was negligible under t

12. SYNTHESIS AND CHARACTERIZATION OF INORGANIC ION EXCHANGERS BASED ON MIXED OXIDE TIN-TITANIUM TO BE USED IN RECOVERY OF CADMIUM AND NICKEL AND PHOTOLUMINESCENT STUDIES / Síntese e caracterização de trocadores iônicos inorgânicos a base de óxidos mistos Estanho-Titânio para utilização na recuperação de Cádmio e Níquel e estudos fotoluminescentes
This work presents the synthesis, characterization and adsorption studies of inorganic ion exchangers based on mixed tin-titanium oxide for recovery of cadmium and nickel metals from aqueous effluents, discarded in the environment mainly through Ni-Cd battery. The exchangers were synthesized by sol-gel modified method using a mixture of tin(IV) chloride and
