Antimonial compounds can be found as a toxic contaminant in the environment. Knowledge on mechanisms of microbial Sb oxidation and its role in microbial tolerance are limited. Previously, we found that Comamonas testosteroni S44 was resistant to multiple heavy metals and was able to oxidize the toxic antimonite [Sb(III)] to the much less toxic antimonate [Sb(V)]. In this study, transposon mutag...

The monitoring of oxyanions in waters, presents significant challenges due to their relatively low concentrations, and a characteristically changeable/unstable/reactive geochemistry with high spatial and temporal turnover. This results in a very heterogeneous pattern of mobility and bioavailability, which is difficult to capture reliably and in a cost effective manner. The diffusive gradients i...

Visceral leishmaniasis (VL, kala-azar) is a zoonotic infection caused by Leishmania species which are transmitted to humans by the bites of infected female phlebotomine sandflies. Leishmania infantum is the responsible species of VL in Aegean, Mediterranean, and Central Anatolia regions of Turkey mainly observed sporadically in pediatric age groups. The aim of this study was to evaluate the cli...

Developments in the determination o some less common anions and in the separation of anions of similar species are described. The anions which are considered are the Group Va hexalluorides. vanadates, tungstates. the per-acids. oxyanions of phosphorus and some organic acids. A new method for the determination of chloride, based on GLC. and capable of very high sensitivity is mentioned. This met...

Recent theoretical studies have suggested that Kitaev physics and such effects as formation of a mysterious spin-liquid state can be expected not only in $\ensuremath{\alpha}\text{\ensuremath{-}}{\mathrm{RuCl}}_{3}$ iridates, but also conventional $3d$ transition metal compounds. Using dc ac magnetometry, thermodynamic, $^{23}\mathrm{Na}$ nuclear magnetic resonance (NMR) measurements we studied...
