Acute myeloid leukemia (AML), one of the most prevalent leukemia types in adults, demonstrates great heterogeneity in molecular and clinical terms. Hence, there is a necessity to the mechanisms involved in AML generation in order to determine optimal treatment. This cross sectional study aimed to assess changes in BECN1 gene expression in with blood samples from 30 AML patients, compared with samples from 15 healthy persons. RNA was extracted and cDNA was synthesized and Real Time PCR applied to determine BECN1 gene expression. The results showed no significant differences in BECN1 gene expression between patients with AML and normal controls (P > 0.05). It appears that expression of BECN1 does not play a significant role in genesis of AML leukemia.
Isotherm and Kinetic Studies in Dyeing of Citric Acid-Crosslinked Cotton with Cationic Natural Dye
Aminoddin Haji,Seyed Mansour Bidoki,Firoozeh Gholami 한국섬유공학회 2020 Fibers and polymers Vol.21 No.11
In this study, cotton fabric was crosslinked with citric acid (CA) in the presence of sodium hypophosphite using apad-dry-cure process under the optimum conditions. The chemistry and morphology of the crosslinked fibers were studiedand compared with the untreated fibers using FTIR and SEM. The crosslinked fabric was dyed with the natural cationic dye,berberine, obtained from the roots of Berberis vulgaris. The effects of dyebath conditions, including dye concentration, pH,and temperature, on the color strength of the dyed samples were investigated, and the mean values were compared usingSPSS. The isotherm and kinetics of the dyeing of the CA-treated fabric with berberine were investigated. The results showedthat the color strength of the dyed samples increased with increasing the dye concentration, pH, and temperature. The bestfittingisotherm and kinetic models were Freundlich and pseudo-second-order models, respectively.

Water pollution control and the development of clean technologies for water, air and soil treatments comprise one of the most important challenges for modern society. Ozone is known as a strong and clean oxidizing agent that can be used for water and wastewater treatment. In this research, a novel Ti/TiHx/SnO₂-Sb₂O5-NiO-CNT modified titanium electrode containing carbon nanotubes (CNT) was fabricated for in-situ ozone generation. The electrode was characterized using SEM, XRD and LSV techniques. CNT presence caused an increase in ozone generation efficiency leading to the higher concentrations of dissolved ozone in water compared to the recently reported researchers. Ozone generation at the surface of the electrode was determined using the standard indigo method. Electrochemical ozone was further used in degradation of C.I. Reactive red 195 (RR 195). It was found that the modified electrode could degrade 96% of RR 195 from initial concentration of 300 mg∙L<SUP>-1</SUP> in 30 min under current density of 20 mA∙cm<SUP>-2</SUP>. COD removal was also measured as high as 60 percent.
FENC: Fast and Efficient Opportunistic Network Coding in wireless networks
( Peyman Pahlavani ),( Vali Derhami ),( Ali Mohammad Zareh Bidoki ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.1
Network coding is a newly developed technology that can cause considerable improvements in network throughput. COPE is the first network coding approach for wireless mesh networks and it is based on opportunistic Wireless Network Coding (WNC). It significantly improves throughput of multi-hop wireless networks utilizing network coding and broadcast features of wireless medium. In this paper we propose a new method, called FENC, for opportunistic WNC that improves the network throughput. In addition, its complexity is lower than other opportunistic WNC approaches. FENC utilizes division and conquer method to find an optimal network coding. The numerical results show that the proposed opportunistic algorithm improves the overall throughput as well as network coding approach.
