[Clinical management of skin necrosis after penis lengthening surgery: Report of 12 cases].

Objective: To analyze the causes of skin necrosis after penis lengthening surgery and corresponding treatment measures, and observe the clinical effect of free skin graft repair in the treatment of penile skin defects.

Methods: We retrospectively analyzed the clinical data on 12 cases of extensive penile skin necrosis and defect after penis lengthening surgery performed in our department from January 2017 to January 2022. The patients underwent free skin graft repair with medium- or full-thickness skin grafts from the thigh after wound preparation.

[Seminal vesiculoscopy: Safe and effective for the treatment of refractory hemospermia].

Objective: To investigate the clinical effect and safety of transutricular seminal vesiculoscopy in the treatment of refractory hemospermia.

Methods: Using 6Fr ureteroscopy through the prostatic utricle, we treated 103 cases of refractory hemospermia with distal seminal duct obstructive lesions, including 12 cases complicated by distal seminal duct cyst. We rinsed the seminal duct cavity, cleaned out the stones, removed the cyst wall with holmium laser and followed up the patients for 12 months postoperatively.

Mechanistic Insights into the Chemo- and Regio-Selective B(CF) Catalyzed C-H Functionalization of Phenols with Diazoesters.

The Lewis acidic B(CF) was recently demonstrated to be effective for the C-H alkylation of phenols with diazoesters. The method avoids the general hydroxyl activation in transition-metal catalysis. -selective C-H alkylation occurs regardless of potential -selective C-H alkylation and O-H alkylation.

Electro-activation of O on MnO/graphite felt for efficient oxidation of water contaminants under room condition.

The activation of oxygen (O) under room condition is highly desirable for oxidative removal of organic pollutants in water. Herein, we report a graphite felt (GF)-supported α-MnO catalyst which is active for activating O with assistance of an anodic electric field. The electro-assisted catalytic wet air oxidation (ECWAO) process on MnO/GF is able to rapidly degrade a variety of dyes, pharmaceutics and personal care products (PPCPs) under room condition.

Silicon/Perovskite Core-Shell Heterojunctions with Light-Trapping Effect for Sensitive Self-Driven Near-Infrared Photodetectors.

In this article, we fabricated a sensitive near-infrared (NIR) light detector by directly coating a layer of Cs-doped FAPbI perovskite film onto vertical Si nanowire (SiNW) array. The as-assembled SiNW array/perovskite core-shell heterojunction exhibits a typical rectifying characteristic in darkness and distinct photoresponse characteristics under light illumination. Owning to the remarkable photovoltaic effect, the heterojunction can work as a self-driven NIR detector without an exterior energy supply.

Mechanistic Insights into Solvent and Ligand Dependency in Cu(I)-Catalyzed Allylic Alkylation with gem-Diborylalkanes.

The recent Cu-catalyzed allylic substitution reaction between gem-diboryalkane and allyl electrophiles shows intriguing solvent and ligand-controlled regioselectivity. The α-alkylation product was obtained in DMF solvent, while γ-alkylation product was obtained in dioxane solvent and the dioxane and NHC ligand situation. In the present study, density functional theory calculations have been used to investigate the reaction mechanism and origin of the regioselectivity.

A novel role of ethephon in controlling the noxious weed Ipomoea cairica (Linn.) Sweet.

Several auxin herbicides, such as 2, 4-D and dicamba, have been used to eradicate an exotic invasive weed Ipomoea cairica in subtropical China, but restraining the re-explosion of this weed is still a challenge. Since ethylene is one of the major intermediate functioning products during the eradication process, we explored the possibility, mechanism and efficiency of using ethephon which can release ethylene to control Ipomoea cairica. The results of the pot experiment showed that 7.

Poly[chlorido[μ(4)-2,2'-(2-methyl-1H-benzimidazol-3-ium-1,3-di-yl)diacetato]-zinc].

The title compound, [Zn(C(12)H(11)N(2)O(4))Cl](n), contains a centrosymmetric dimetal tetra-carboxyl-ate paddle-wheel moiety in which the Zn(II) atom is square-pyramidally coordinated by four carboxyl-ate O atoms at the basal positions and one Cl(-) anion at the apical position. Each paddle-wheel unit is joined to four such neighbours through bridging dicarboxyl-ate ligands, producing a two-dimensional undulating layer parallel to (-101). Adjacent sheets are stacked in a parallel fashion to form a three-dimensional supra-molecular structure which is stabilized by inter-layer π-π inter-actions between benzene rings, with a centroid-centroid distance of 3.

Poly[di-μ(3)-chlorido-di-μ(2)-chlorido-{μ(4)-N,N,N',N'-tetra-kis-[(diphenyl-phosphan-yl)meth-yl]benzene-1,4-diamine-κ(4)P:P':P'':P'''}tetra-copper(II)].

In the title complex, [Cu(4)Cl(4)(C(58)H(52)N(2)P(4))](n), four Cu(II) atoms are held together via two doubly bridging and two triply bridging chlorides, forming a stair-like Cu(4)Cl(4) core having crystallographically imposed inversion symmetry, while the benzene-1,4-diamine ligand (with a crystallographic inversion center at the centroid) acts in a tetra-dentate coordination mode, bridging two adjacent Cu(4)Cl(4) cores, resulting in a chain along the a-axis direction. One Cu atom has a distorted tetra-hedral geometry, coordinated by one P atom, one μ(2)-Cl and two μ(3)-Cl atoms, while the second Cu atom adopts a trigonal geometry, coordinated by one P atom, one μ(2)-Cl and one μ(3)-Cl atoms.

Fluorescence studies of interaction between flavonol p-coumaroylglucoside tiliroside and bovine serum albumin.

In this paper, the interaction between flavonol p-coumaroylglucoside tiliroside and BSA was investigated by fluorescence quenching spectra, synchronous fluorescence spectra, and three-dimensional fluorescence spectra under simulative physiological conditions. It was proved that the fluorescence quenching of BSA by tiliroside was mainly a result of the formation of a tiliroside-BSA complex. The modified Stern-Volmer quenching constant and the corresponding thermodynamic parameters DeltaH, DeltaG and DeltaS at different temperatures were calculated.
