We encountered a very rare condition where the patient had a lymphocele under the skin envelope of the breast following mastectomy during the course of breast reconstruction with a tissue expander. The incidence rate of axillary lymphoceles is reported as 2.2-50% in breast cancer patients, but there have been no reports mentioning lymphoceles under the breast skin during the course of breast re...

The title compound, C17H24N2O3S, was synthesized in order to determine the relative configuration of the corresponding β-keto aldehyde. In the U-shaped mol-ecule, the five-membered ring approximates an envelope, with the methyl-ene C atom adjacent to the quaternary C atom being the flap, and the methyl and isopropyl substituents lying to the same side of the ring. The dihedral angles between th...

IN THE TITLE COMPOUND (SYSTEMATIC NAME {(3aS,5S,6R,6aS)-3a-[(benz-yloxy)meth-yl]-6-hy-droxy-2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxol-5-yl}methyl 4-methyl-benzene-sulfonate), C23H28O8S, the absolute structure and relative stereochemistry of the four chiral centres have been established by X-ray crystallography, with the absolute configuration inferred from the use of l-sorbose as the sta...

The title compound, C15H19NO4, is the a product of the esterification of the corresponding carbonic acid with methanol. The mol-ecule comprises a fused tetra-cyclic system containing three five-membered rings (2-pyrrolidinone, tetra-hydro-furan and di-hydro-furan) and one seven-membered ring (azepane). The five-membered rings have the usual envelope conformations, with the quaternary C atom bei...

The title compound, C16H16BrNO4, has two adjacent chiral C atoms and both have an S configuration. The fused cyclo-hex-2-enone and di-hydro-furan rings both adopt envelope conformations, with the quaternary C atom and the nitro-substituted C atoms as the respective flap. The flap atoms lie 0.607 (3) and -0.253 (2) Å, respectively, from the mean plane of the remaining ring atoms on opposite side...

Nipple-areolar complex (NAC) malposition is one of the most common complications following nipple-sparing mastectomy with implant-based reconstruction. To maximize perfusion to the NAC, traditional methods of correcting NAC malposition limit undermining below the NAC. We demonstrate a series of cases in which improvement of NAC malposition was safely performed by reelevating the NAC and mastect...

In the title compound, C(36)H(32)N(2)O(4)S, the piperidine ring adopts a chair conformation, while the five-membered pyrrolidine (with a C atom as the flap atom) and thia-zolidine (with the S atom as the flap atom) rings adopt envelope conformations. The naphthalene ring system makes dihedral angles of 18.82 (5) and 40.92 (5)° with the two meth-oxy-substituted benzene rings. In the crystal, cen...

In the title compound, C23H23NO8, the dihedral angle between the five- and six-membered rings of the indene-dione moiety is 3.09 (13)°. The mean plane of the five-membered ring (which has a flat envelope conformation with the spiro C atom as the flap) is inclined to the mean plane of the central five-membered ring of the pyrrolizine unit by 76.48 (12)°. This central ring has a twist conformatio...

We have performed a form of lunate replacement arthroplasty, which included excision of the lunate and insertion of a vascularised radial bone flap wrapped in pronator quadratus, for stage IIIB or stage IV Kienböck's disease, in 41 patients who have been followed up for more than three years. All patients reported an improvement in their symptoms, and 20 of the 41 became free of pain after the ...

Glycoprotein H (gH) is an envelope protein conserved in the Herpesviridae. Together with glycoprotein B (gB), the heterodimeric complex of gH and glycoprotein L (gL) mediates penetration and direct viral cell-to-cell spread. In herpes simplex and pseudorabies virus (PrV), coexpression of gH/gL, gB, and gD induces membrane fusion to form polykaryocytes. The recently determined crystal structure ...
