UV is one of the major causes of DNA damage induced apoptosis. However, cancer cells adopt alternative mechanisms to evade UV-induced apoptosis. To identify factors that protect cancer cells from UV-induced apoptosis, we performed a genome wide short-hairpin RNA (shRNA) screen, which identified Zinc finger protein 598 (ZNF598) as a key regulator of UV-induced apoptosis. Here, we show that UV ir...

This paper reports the synthesis and characterization of photocatalyst CdS nanoparticles for investigation of photocatalytic degradation of 2,4,6-trichlorophenol. CdS nanoparticles were synthesized by the microwave-assisted sol-gel method and characterized by various techniques such as X-ray diffraction, filed emission scanning electron microscopy, energy dispersive spectroscopy, Fourier transf...

tripropylammonium fluorochromate(vi) (tpafc), is an efficient and new reagent, which isprepared easily and oxidizes thiols to the corresponding disulfides, quickly. the reactions areperformed cleanly and are controlled to stop at the disulfide stage, without over-oxidation andside products. coupling of thiols to their corresponding disulfides, are studied in solution atroom temperature and in s...

a new dimeric orthopalladated complex was synthesized via reaction of 2,3-dimethoxy benzaldehyde oxime with palladium chloride and lithium chloride in methanol as solvent and sodium acetate as base at room temperature. the catalytic activity of this dimeric [pd{c6h2(-ch=noh)-(ome)2-2,3}(µ-cl)]2 complex as an efficient, air, and moisture tolerant catalyst was investigated in mizoroki–heck cross ...

the aim of this study was to degrade furfural by a new nanotube system. to degrade some organic pollutants as well as to reduce the amount of furfural which is a well-known pollutant in oil industry, the photocatalytic process along with ultraviolet (uv) irradiation may be employed. in this study, the uv/tio2/pd system in which the nanoparticles of palladium doped into the titanium dioxide was ...

background: various prokaryotic and eukaryotic expression systems have been developed for the production of recombinant proteins. in the present study, we used a new protein expression system based on the iranian lizard leishmania, a trypanosomatid protozoan as a host, for the expression of lpg3 gene from leishmania infantum (l.infantum). methods: the lpg3 gene was cloned in the expression cass...

Hyssopus of­ficinalis L. is one of the most important medicinal plants. Medicinal herbs are contaminated by microorganisms. Conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

We have investigated the use of Leishmania cells as a novel eukaryotic expression system for the production of recombinant protein. These cells are easy to maintain, requiring no CO2 incubator or shaker, and can be grown in standard tissue culture media. Leishmania cells can be readily transfected with plasmid DNA by electroporation and transformants selected with antibiotic resistance. Recent ...

We present a rapid and highly efficient method to form microstructure of poly(ethylene glycol) (PEG)-based acrylates by microwave-induced thermal crosslinking. PEG-based polymeric microstructures such as polymer microarrays and microwells were fabricated on 3-(trimethoxysilyl)propyl methacrylate (TMSPMA)-coated glass slides that were placed on top of a silicon wafer. In comparison to ultraviole...
