BACKGROUND Miltefosine (MF) is the first oral compound used in the chemotherapy against leishmaniasis. Since the mechanism of action of this drug and the targets of MF in Leishmania are unclear, we generated in a step-by-step manner Leishmania major promastigote mutants highly resistant to MF. Two of the mutants were submitted to a short-read whole genome sequencing for identifying potential ge...

The LiMn1.5Ni0.5O4 spinel is an important lithium ion battery cathode material that has continued to receive major research attention because of its high operating voltage (∼4.8 V). This study interrogates the impact of microwave irradiation on the Mn(3+) concentration and electrochemistry of the LiMn1.5Ni0.5O4 spinel. It is shown that microwave is capable of tuning the Mn(3+) content of the sp...

the first highly accelerated niementowski reaction of anhranilic acid with some amides or ketones under microwave irradiation leading to quinazolinones and quinoline derivatives is described. these reactions represent some examples of efficient microwave irradiation promoted organic condensation in which the reactions can be carried out in open vessels and provides products of high purity with ...

High crystallinity of ZnWO4 nanoparticles has been successfully synthesized via a highly effective and environmentally friendly microwave route by controlling the reaction time and temperature. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and Fourier infrared spectrum (FT-IR). The crystallinity was enhanced with the increase of the r...

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...

p53-mediated increase in cyclin-dependent kinase inhibitor p21(WAF1) protein is thought to be the major mediator of cell cycle arrest after DNA damage. Previously p21 protein levels have been reported to increase or to decrease after UV irradiation. We show that p21 protein is degraded after irradiation of a variety of cell types with low but not high doses of UV. Cell cycle arrest occurs despi...

   Nickel-molybdenum oxidebimetallic nanoparticles were synthesized in ethylene glycol using the microwave irradiation technique. According to the results, successive reduction of nickel and molybdenum ions, followed by thermal treatment of obtained nanoparticles led to formation of core-shell structured nickel-molybdenum oxide nanoparticles. According to the results, the thickness of the s...

An efficient synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles by one-step condensation of  an aldehyde, benzil, ammonium acetate and primary amine in the presence of nanocrystalline magnesium aluminate under microwave irradiation is described. The advantages of this catalyst are including simple work-up, low cost and reusability. Compared with conventional methods, the ...

In both natural and agricultural conditions, plants are frequently subjected to unfavourable environments, resulting in varying degrees of stress. UV irradiation, drought, heat shock, chilling/freezing, salinity and oxygen deficiency are a few of the major abiotic factors restricting plant growth and development. An important consequence of stratospheric ozone depletion is increased transmissio...

In this study, 5,10,15,20-tetrakis(4-nitrophenyl)porphyrin (TNPP) and its zinc porphyrin complex (ZnTNPP) were synthesized in situ using the microwave method and identified by UV-Vis, FT-IR and 1H NMR. The photostability and photodynamic antimicrobial activity (PACT) of these compounds were investigated on Pseudomonas aeruginosa and Bacillus subtilis under visible light irradiation. MIC, MBC an...
