Interactions of recombinant N-lobe of human serum transferrin (hTF/2N) with Bi3+, a metal ion widely used in medicine, have been investigated by both UV and NMR spectroscopy. The bicarbonate-independent stability constant for Bi3+ binding (K*) to hTF/2N was determined to be log K* 18.9+/-0.2 in 5 mM bicarbonate/10 mM Hepes buffer at 310 K, pH7.4. The presence of Fe3+ in the C-lobe of intact hTF...

Alkaline earth elements and alkali metals (Mg, Ca, Na and K) play an important role in the geochemical evolution of saline lakes as the final brine type is defined by the abundance of these elements. The role of major ions in brine evolution has been studied in great detail, but little has been done to investigate the behaviour of minor alkali elements in these systems despite their similar che...

Air conditioner is an equipment which present in most buildings around the world, either serving to provide greater thermal comfort its users, or as part of industrial processes. This while operation produces water from condensation air contact with coil, has potential be used for non-potable purposes within buildings. study aims evaluate quality condensate conditioners purposes. Water collecti...

alpha-Synuclein, a neuronal presynaptic protein, has been reported to undergo oligomerization to form toxic Lewy bodies in neurodegenerative disorders. One of the proposed mechanisms for aggregation of alpha-synuclein involves oxidative and nitrative modifications. In the present study, we show that addition of 3-morpholino-sydnonimine chloride (SIN-1) or slow infusion of pre-formed peroxynitri...

Due to climate change impacts, seawater intrusion is a major issue in various river deltas around the globe, including Indus delta, Pakistan. The has severely affected freshwater resources as well livelihood of people living delta. Thus, this study was aimed evaluate subsurface into delta based on groundwater quality data. Around 180 samples, randomly collected from area, were analyzed for chlo...

Experimental setups to study modes of inorganic carbon acquisition and fixation rates by marine phytoplankton commonly make use of so-called disequilibrium techniques. The chemical or isotopic disequilibrium, either caused by phytoplankton cells taking up inorganic carbon or by a small disturbance of the isotopic equilibrium in the carbonate system, requires to account for the relatively slow c...

Electrocatalytic CO2-reduction technology can convert CO2 into methanol and other chemicals using renewable electricity, but the techno-economic prospects of large-scale electrocatalytic reduction in are not clear. This paper conducted sensitivity analysis to confirm key parameters affecting cost production from an alkaline flow cell a neutral MEA electrolyzer, compared two electrolyzers under ...
