Introduction. Tumor lysis syndrome is an emergency condition requiring prompt recognition and treatment. It?s a consequence of spontaneous or therapy-induced cellular death leading to the release intracellular ions metabolic products purine bases into bloodstream. Pathophysiology. The characteristic derangement comprises hyperkalemia, hyperphosphatemia, hyperuricemia, hypocalcemia. These change...

We introduce an effective tight-binding model to discuss penta-graphene and present an analytical solution. This model only involves the π-orbitals of the sp(2)-hybridized carbon atoms and reproduces the two highest valence bands. By introducing energy-dependent hopping elements, originating from the elimination of the sp(3)-hybridized carbon atoms, also the two lowest conduction bands can be w...

The title tricyclic diene, C(24)H(22)Cl(2), is the product of thermal ring-opening of a corresponding basketane (penta-cyclo-[4.4.0.0(2,5).0(3,8).0(4,7)]deca-ne) derivative. The cyclo-butene ring is planar to within 0.0032 (12) Å and its geometry is normal. The two 4-chloro-phenyl groups are oriented in an approximately face-to-face conformation with a dihedral angle of 44.14 (6)° between them....

The title compound, C(10)H(11)N(2)O(2)P·H(2)O, contains a tetra-coordinate penta-valent P atom. The phosphinate group plays a predominant role in the cohesion of the crystal structure by forming chains along the b axis via inter-molecular C-H⋯O hydrogen bonds. These chains are connected by O-H⋯O and N-H⋯O hydrogen bonding involving the lattice water.

Transient carbonyl nitrenes RC(O)N, formed during thermal- or photoinduced decomposition of carbonyl azides RC(O)N3, are highly liable to the Curtius rearrangement, producing isocyanates RNCO in almost quantitative yield. Contrary to common belief, we found a thermally persistent triplet carbonyl nitrene, FC(O)N, that can be produced by flash pyrolysis of FC(O)N3 in 49% yield. The computed CBS-...
