We present a 42-year-old patient who was examined in the Gastroenterology Department of Gaziantep University for chronic abdominal pain, nausea and vomiting. Ultrasonography showed a 4.7 cm solid hepatic mass on the right lateral side of the right lobe of the liver. The patient was then sent to the Nuclear Medicine Department of Gaziantep University for liver scan. After injecting autologous re...
The short-lived unstable isotopes with half-lives of 0.1–10 My have been used as nuclear cosmochronometers to evaluate from an astrophysical event such supernova (SN) explosion or AGB s-process the solar system formation. We proposed shorted-lived radioisotopes 92 Nb and 98 Tc for neutrino-process
Methotrexate (MTX) is being used in clinical oncology for the treatment of a wide variety of cancers. The aim of the present study was to label directly MTX with (99m)Tc by using Sn/pyrophosphate as reducing agent and to use this labeled compound as a potential anticancer radiopharmaceutical for breast cancer imaging. We studied the labeling efficiency of the (99m)Tc-MTX compound by paper chrom...
Sulfur is a cathode material for lithium-ion batteries with a high specific capacity of 1675 mAh/g. The rapid capacity fading, however, presents a significant challenge for the practical application of sulfur cathodes. Two major approaches that have been developed to improve the sulfur cathode performance include (a) fabricating nanostructured conductive matrix to physically encapsulate sulfur ...
The purple photosynthetic sulfur bacterium, Chromatium, will grow only in the light and under anaerobic conditions. This organism can grow on an inorganic medium utilizing CO2 as the sole carbon source in the presence of reduced inorganic sulfur compounds. Some reduced carbon compounds can be utilized for the growth of this organism but only in the light and under anaerobic conditions. In this ...
The influence of sodium chloride on dissolution of chalcopyrite and surface sulfur speciation during bioleaching of chalcopyrite with the extreme thermophile Acidianus manzaensis YN-25 was studied. The addition of sodium chloride accelerated the dissolution of chalcopyrite by reducing the accumulation of elemental sulfur layers on the mineral surface, resulting in an increase in the concentrati...
Studies directed toward the oxidative and reductive desulfurization of readily available 20-S-aryl-20thiouridine derivatives were investigated with the prospect to functionalize the C20-position of nucleosides. The oxidative desulfurization-difluorination strategy was successful on 2-(arylthio)alkanoate surrogates, while extension of the combination of oxidants and fluoride sources was not an e...
Graphene-sulfur composites with sulfur fractions as high as 87 wt% are prepared using a simple one-pot, scalable method. The graphene envelops the sulfur particles, providing a conductive shrink-wrap for electron transport. These materials are efficient cathodes for Li-S batteries, yielding 93% coulombic efficiency over 50 cycles with good capacity.
The importance of the sulfur-fluorine bond is starting to increase in modern medicinal chemistry literature. This is due to a better understanding of the stability and reactivity of this moiety depending on the various oxidation states of sulfur. Furthermore, several commercial reagents used for mild and selective fluorination of organic molecules are based on the known reactivity of S-F groups...
