The in vivo efficacy of highly porous carbon nanocomposites prepared from sugar beet waste for the Ochratoxin A detoxification. Vet. arhiv 89, 851-872, 2019. ABsTrACTThe aim of this study was to develop highly porous carbon nanocomposites for detoxification of ochratoxin A (OTA) in broilers. One-day-old chicks were divided into six groups (A to F). Group A was given pure feed. Group B was given 400 µg/kg of OTA contaminated feed, while the rest of the groups were fed on 400 µg/ kg of OTA contaminated feed plus a different level of the adsorbent. The clinical signs of the positive control (group B) such as depression, diarrhea, increased water intake, low body weight, a high degree of genotoxicity, and swollen and hemorrhagic kidneys and liver, were compared with the other groups. In group B chicks, the serum ALT (alanine transferase), ALP (alkaline phosphatase), creatinine and urea levels were significantly higher, while albumin, globulin and total proteins levels were significantly lower than in negative control group A. The adsorbent treated groups showed almost normal clinical signs. Group C and D were affected to some extent, however, groups E and F showed undamaged DNA, normal behavior and blood biochemistry, and wellmaintained histological structure, like that of the negative control group.

Aflatoxins are a kind of mycotoxins that are mostly produced by a group of molds such as Aspergillus flavus and Aspergillus parasiticus. The studies on different parts of Iran showed that AFM 1 infection of milk is higher than European Union's standard. In this study, the specific aptamer with the carboxylic group at the end of 5′ and Fe 3 O 4 nanoparticles with amine groups was synthesized. Morphological and structural qualities of Fe 3 O 4 were determined by the Fourier-transform infrared spectrograph (FTIR), dynamic light scattering, scanning electron microscope, and X-ray diffraction devices. The specificity of the aptamer to AFM 1 was investigated in adjacent of AFM 1 and aflatoxin B 1 . Then, aptamers were attached to nanoparticles to improve synthetic qualities and to ease of its detachment. The attachment was approved by FTIR method. The complex (Fe 3 O 4 -APT) was then added to infected milk and after the proper time was detached from the milk using a magnet. The remained amount of AFM 1 was attained in milk using high-performance liquid chromatography. Our result showed that this method for aflatoxin detoxification is much more effective than conventional methods based on recognition of AFM 1 and their concentration in infected milk. This method is more applicable, faster, and cheaper highlighting its application in milk factories.

“…The sorption capacity and the amount of Zn(II)/Pb(II) ions adsorbed by nano-HAP particles (mg/g) were determined by the following equation: (1) where Q designates heavy metal ions uptake (mg/g), C i represents the pollutant's concentration in the initial solution (mg/L), C e is the pollutant's concentration in the solution at equilibrium (mg/L), V -solution's volume (L), and m -mass of nano-HAP used (g). HAP nanopowders were investigated into the removal process of Zn(II) and Pb(II) from single and binary aqueous solutions.…”

A kinetic study has been carried out with two hydroxyapatite nanopowders to establish the mechanism involved in heavy metals removal from aqueous synthetic solutions. The samples of nanohydroxyapatite have been previously characterized. The first sample represents a pure hydroxyapatite (HAP) nanopowder named HAP-1, and the second sample (HAP-2) consist of a mixture of hydroxyapatite (HAP; Ca10(PO4)6(OH)2) and b-tricalcium phosphate (b-TCP; Ca3(PO4)2). Batch experiments with single and binary Zn(II) and Pb(II) aqueous solutions have been performed. According to this research study, it was found that the both nanohydroxyapatite samples show good heavy metals adsorption capacity, and selectivity for Pb(II) ions. A more pronounced decreasing of sorption capacity of Zn(II) ions from binary solutions compared to that registered from single heavy metal ion solutions has been observed. From the kinetic point of view, the sorption process can be described for both heavy metals as a pseudo-second-order kinetic process. According to this model, the Zn(II) and Pb(II) sorption can be achieved by chemical reactions between heavy metals and functional groups of adsorbents. The obtained results are indicative of good hydroxyapatite adsorption ability towards Pb(II) and Zn(II) ions.
