Surgical considerations in the resection of solitary fibrous tumors of the pleura.

Solitary fibrous tumors (SFTs) are rare mesenchymal pleural neoplasms with an overall good prognosis and low recurrence rate if completely resected and if degree of differentiation is favorable. Within the last decade, advances in research have led to more reliable methods of differentiating SFTs from other soft tissue tumors. Historically, several markers were used to distinguish SFTs from similar tumors, but these markers had poor specificity.

Synthesis, Spectroscopic Characterization, Antibacterial Activity, and Computational Studies of Novel Pyridazinone Derivatives.

In this work, a novel series of pyridazinone derivatives (-) were synthesized and characterized by NMR (H and C), FT-IR spectroscopies, and ESI-MS methods. All synthesized compounds were screened for their antibacterial activities against (Methicillin-resistant), , , , and . Among the series, compounds and were found to be active against (MRSA), , and with the lowest MIC value range of 3.

Crystal structure of ()-3-({6-[2-(4-chloro-phen-yl)ethen-yl]-3-oxo-2,3-di-hydro-pyridazin-4-yl}meth-yl)pyridin-1-ium chloride dihydrate.

In the title compound, CHClNO·Cl·2HO, three intra-mol-ecular hydrogen bonds are observed, N-H⋯O, O-H⋯Cl and O-H⋯O. In the crystal, mol-ecules are connected by C-H⋯Cl and N-H⋯O hydrogen bonds. Strong C-H⋯Cl, N-H⋯O, O-H⋯Cl and O-H⋯O hydrogen-bonding inter-actions are implied by the Hirshfeld surface analysis, which indicate that H⋯H contacts make the largest contribution to the overall crystal packing at 33.

Crystal structure and mol-ecular docking study of diethyl 2,2'-({[(1,1')-(hydrazine-1,2-diyl-idene)bis-(methanylyl-idene)]bis-(4,1-phenyl-ene)}bis-(-oxy))di-acetate.

The title Schiff base, CHNO, adopts an configuration. The mol-ecule is planar, the mean planes of the phenyl ring system (r.m.

Crystal structure and Hirshfeld surface analysis of 6-(()-2-{4-[2-(4-chloro-phen-yl)-2-oxoeth-oxy]phen-yl}ethen-yl)-4,5-di-hydro-pyridazin-3(2)-one.

The pyridazine ring in the title compound, CHClNO, adopts a screw-boat conformation. The whole mol-ecule is flattened, the dihedral angles subtended by the least-squares plane of the central aromatic ring with those of the terminal benzene and pyridazine rings being 15.18 (19) and 11.
