در کار حاضر، سه رنگ آنیونی reactive yellow 145,reactive blue19 و reactive red195 برای حذف انتخاب شدند. روش حذف به کار برده شده، با استفاده از جاذب نانولوله¬های کربنی اصلاح شده با نانوذرات مغناطیسی fe3o4 انجام شد. مشخصات نانوذرات آماده شده توسط tem,xrdو vsm تعین گردید. جاذب مغناطیس آماده شده می¬تواند بخوبی در آب حل شده و به آسانی توسط آهنربا از محیط جدا می¬گردد. متغیر¬هایی که معمولا بر کارایی فر...
Physical activities are associated with increased production of reactive oxygen species. The production of reactive oxygen species is dependent of the intensity, duration and type of activity. Although the physiological amounts of reactive oxygen species are necessary to regulate cell reactions, their excessive production can cause numerous damages to the structure and function of cells and wea...
Traumatic brain injury (TBI) is a disruption in the brain functions following a head trauma. Cell therapy may provide a promising treatment for TBI. Human neural stem cells cultured in self-assembling peptide scaffolds have been proposed as a potential novel method for cell replacement treatment after TBI. In the present study, we accessed the effects of human neural stem/progenitor cells (hNS/...
Objective(s): This study focused on determining cytotoxic effects of copper oxide nanoparticles (CuO NPs) on chronic myeloid leukemia (CML) K562 cell line in a cell-specific manner and its possible mechanism of cell death. We investigated the cytotoxicity of CuO NPs against K562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). Materials and Methods: The toxicity w...
Background: Few studies regarding oral lesions of children and adolescents were reported in the medical literature. The aim of this study was to determine the frequency of these lesions in patients from birth to 20 years old in Babol, Northern Iran.Methods: The slides of all cases of oral lesions in children and adolescents, between 1990 and 2012 were obtained from the pathology archives of Sha...
The Bombay (Oh) Phenotype is a rare blood group. Phenotypes of this group lack H antigens on their red blood cell membrane and have strongly reactive anti-H in the serum for which patients can receive only autologus or Bombay phenotype red blood cells. We report three cases with Bombay blood group in the city of Yazd to emphasize the transfusion challenges in such patients.
Paradoxically, death is an integral part of life. Cell death is essential for growth and development of eukaryotes, by maintaining tissue and organ homeostasis in concert with cell proliferation, growth, and differentiation. Until recently, the wide variety of cell death types reported in the literature was mostly caged in two semantic categories: apoptosis and necrosis. Discrimination between ...
Cell-based biosensors have become a research hotspot in biosensors and bioelectronics fields. The main feature of cell-based biosensors is the immobilization of living cell on the surface of transducers. Different types of polymers which are used as scaffolds for cell growth should be biocompatible and have reactive functional groups for further attachment of biomolecules. In this work, the cel...
a rapid isocratic method of high performance liquid chromatography system (hplc) with a glassy carbon working electrode of electrochemical detector is set up for quantitative detection of trace amount of nitrite ion (no2¯) in aqueous protein containing cell lysate, cell media, plasma, serum, urine and other body fluids. the solid extraction reversed phase cartridges (sep-pak) are used for dep...
