Slow evaporation of the filtrate derived from the reaction in water between 2-thiobarbituric acid (H2TBA) and equimolar amount of potassium hydroxide results in the formation of crystals of two coordination polymers: unhydrated [K(μ 3-S,O-HTBA)]n (1) and hydrated [K(μ 2-S,O-HTBA)(...
Carbonic anhydrase inhibition could block proximal tubule potassium reabsorption and increase delivery to the distal tubule, but the reported effects of carbonic anhydrase inhibition on proximal tubule transport have been conflicting. Whereas CAI decreases proximal tubule sodium, bicarbonate, and water ...
(4) was used to calculate, at the reference temperature (θ = 298.15 K), the enthalpy changes values of protonation, after the conversion in the molal concentration scale of the corresponding protonation constants:(4)logβH=logβHθ+ΔHθ/2.303R) (1/θ –1/Twhere: T is the ...

relatively low conversion efficiency, which is evaluated by the TE figure of merit, zT = (S2T)/(ρ(κE+κL)), where S, T, ρ, κE and κL are the Seebeck coefficient, absolute temperature, electrical resistivity, and electronic and lattice contributions to the thermal conductivity, ...
In the structure of the BC_CO2 and BC_H3PO4 materials, there are also heteroatoms, such as oxygen, nitrogen, phosphorous, silicon, chlorine and sulfur, and metals, like potassium, calcium, iron and magnesium. These elements can originate from waxes, pesticides, microorganisms, larvae residues,...
to the parent drug. However, the absorption of the formed GSK254 is negligible and this is supported by the PO-ADME study in which the faeces losses were >94% in the parent drug [12]. Moreover, no GSK254-glucoronide was detected in the faeces, suggesting almost complete conversion of ...

Synthetic potassium birnessite (δ-MnO2, hereafter MnO2) was synthesized according to previous investigations [15]. Briefly, 1 L of heated (60 ◦C) 0.4 M KMnO4 was reacted with 0.5 L heated (60 ◦C), concentrated HCl followed by storage in dialysis tubing immersed in DI water for 14 ...
