[LAPAROSCOPIC LIVE DONOR NEPHRECTOMY WITH HORSESHOE KIDNEY: A CASE REPORT].

We performed laparoscopic live donor nephrectomy (LDN) on approximately 200 patients in Ehime Prefectural Center Hospital between 2003 and 2016. In 2016, a fifty-something woman who was a donor candidate for her husband was revealed to have a horseshoe kidney through contrast-enhanced computed tomography; other LDN procedures used a retroperitoneal approach, but this one used a transperitoneal approach since the latter approach allowed for a more favorable visual field. The left kidney was selected since renal scintigraphy showed equal bilateral renal function and renal arteries are simpler on the left side.

Impact of ultra-long second-generation drug-eluting stent implantation.

Objectives: This study investigated the safety and prognosis of ultra-long second DES (UL-2nd DES) implantation in real-world practice.

Background: Long stenting is a widely known predictor of stent thrombosis (ST) or target lesion revascularization (TLR) in first-generation drug-eluting stents (DES).

Methods: Participants were 1,669 patients (2,763 lesions) who had undergone successful second DES implantation; they were assigned to one of three groups: ultra-long 2nd DES (UL-DES; >50 mm, 166 patients, 259 lesions), long second DES (L-DES; 20-50 mm, 758 patients, 1,212 lesions), or short second DES (S-DES; <20 mm, 745 patients, 1,292 lesions).

Direct catalytic asymmetric alkynylation of ketoimines.

An efficient protocol for direct catalytic alkynylation of ketoimines is described. The simultaneous activation of a soft Lewis basic terminal alkyne and a ketoimine bearing a thiophosphinoyl group by soft Lewis acid Cu(I) is crucial for high conversion. The reaction can be rendered asymmetric with a chiral bisphosphine ligand (S,S)-Ph-BPE.

Intermediate as catalyst: catalytic asymmetric conjugate addition of nitroalkanes to α,β-unsaturated thioamides.

Catalytic asymmetric conjugate addition of nitroalkanes to α,β-unsaturated thioamides is promoted by a mesitylcopper/(R)-DTBM-Segphos precatalyst, affording γ-nitrothioamides in moderate to high syn-selectivity and excellent enantioselectivity. The intermediate Cu-thioamide enolate functions as a soft Lewis acid/hard Brønsted base cooperative catalyst to drive the catalytic cycle efficiently under proton transfer conditions.

Direct catalytic asymmetric aldol reaction of beta-keto esters with formaldehyde promoted by a dinuclear Ni2-Schiff base complex.

A homodinuclear Ni(2)-Schiff base 1 complex (0.1-1 mol%) promoted the direct catalytic asymmetric aldol reaction of beta-keto esters with formaldehyde, giving hydroxymethylated adducts in 94-66% ee.

Catalytic asymmetric synthesis of 3-aminooxindoles: enantiofacial selectivity switch in bimetallic vs monometallic Schiff base catalysis.

A highly enantioselective catalytic asymmetric access to 3-aminooxindoles with a tetrasubstituted carbon stereocenter is described. 1-2 mol % of homobimetallic (R)-Ni(2)-Schiff base 1 catalyzed the asymmetric amination of 3-substituted oxindoles with azodicarboxylates to give (R)-products in 99-89% yield and 99-87% ee. Reversal of enantiofacial selectivity was observed between bimetallic and monometallic Schiff base complexes, and monometallic (R)-Ni-Schiff base 2c gave (S)-products in 98-80% ee.

Mono- and penta-addition of enol silyl ethers to [60]fullerene.

The reaction of 1-alkoxy-1-siloxyethene with [60]fullerene in 20% DMSO/chlorobenzene at ambient temperature under an oxygen atmosphere gave a penta-addition product, while the reaction of 1-alkoxy-1-siloxyalkenes or 1,2-siloxyalkenes under argon gave monoaddition products. The new method has merits over the previously reported syntheses of these compounds in that the synthesis does not require the use of heavy metals or photolysis conditions, and it can be carried out under simple and mild conditions.
