The formation of oxalates in soils and rocks under conditions cryoarid climate, permafrost taiga vegetation was studied. Whewellite weddellite were found four areas associated with the mining industry: on kimberlite deposit Daldyn territory, lower reaches Markha River Central Yakut Plain, coastal outcrop Allah-Yun Sellah-Khotun ore cluster. upper organic horizon Skeletic Cryosol (Thixotropic) (...

Effective fluorescent sensing of oxalate in water is significant but still remains a challenge. By using indicator-displacement assays, a readily available macrocyclic copper(II) complex was found to show a sensitive off-on fluorescent sensing for oxalate with high selectivity and high binding affinity (>10(7) M(-1)) in water at neutral pH.

Serum Vitamin A, total protein, serum electrophoresis, were determined in pediatric patients with urolithiasis (mostly bladder stones) and compared to that of normal healthy volunteers. The level of Vitamin A in healthy volunteers was found to be significantly (P<0.001) higher than that of patients with urolithiasis. The amount of total serum protein, how­ever, was not significantly different i...

Ex vivo conversion of the anti-influenza drug oseltamivir to its active metabolite can be inhibited by the esterase inhibitor dichlorvos or by using commercial fluoride-oxalate tubes. Oseltamivir and its active metabolite remain intact in plasma samples during a proposed virus heat inactivation step: incubation at 60 degrees C for 45 min.

In the hydro-thermally synthesized title compound, [Ce(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the Ce(III) ion is coordinated by four O atoms from two different oxalate ligands, three O atoms from two symmetry-related pyrazine-2-carboxyl-ate ligands, two O atoms from two water melecules and one N atom from a pyrazine-2-carboxyl-ate ligand in a distorted bicapped square-anti-prismatic coordin...

Plant-based foods are rich sources of vitamins and essential micronutrients. For the proper functioning human body their crucial role, trace minerals (iron, zinc, magnesium, manganese, etc.) required in appropriate amounts. Cereals pulses chief these minerals. Despite minerals, adequate consumption plant cannot fulfill body’s total nutrient requirement. Plant also contain ample amounts anti-nut...
