PURPOSE In this work, we propose an in situ precise electrospinning of medical glue fibers onto dural wound for improving sealing capability, avoiding tissue adhesion, and saving time in dural repair. METHODS N-octyl-2-cyanoacrylate, a commercial tissue adhesive (medical glue), can be electrospun into ultrathin fibrous film with precise and homogeneous deposition by a gas-assisted electrospin...

Cyanoacrylates have been recognized since before the 1960s as excellent tissue adhesives. They are easy to use, cost-effective, and cosmetically favorable. There are no studies from India reporting the use of tissue adhesives in laparoscopic surgery. We carried out a prospective, interventional, randomized trial of non-absorbable simple interrupted sutures versus 2-octyl cyanoacrylate in the cl...

In cases of auricular surgery, postoperative dressings are thought to be important for keeping auricular contour and in helping to prevent from dressing failures due to edema or subcutaneous hematoma, which may result in fibrous or cartilaginous proliferation. However, it is often difficult to achieve success with standard dressings because of the complicated shape of the auricle. We used 2-oct...

The relationship between calcium ions and the differentiation of human promyelocytic leukemia HL-60 cells was investigated. Proliferation of HL-60 cells incubated in calcium-free medium was inhibited without cell differentiation. On the other hand, incubation with 100 /¿Mverapamil markedly inhibited cell proliferation and caused slight cell differentiation into monocytes. Both calcium-free med...

A flow injection analysis (FIA) system comprising a tartrate-(TAT) selective electrode has been developed for determination of tartaric acid in wines. Several electrodes constructed for this purpose had a PVC membrane with a complex of quaternary ammonium and TAT as anion exchanger, a phenol derivative as additive, and a more or less polar mediator solvent. Characterization of the electrodes sh...

In the title compound, C(15)H(22)N(2)O, the octyl group adopts an all-trans conformation. In the crystal, mol-ecules form centrosymmetric dimers with an R(2) (2)(8) graph-set motif, linked by pairs of N-H⋯O hydrogen bonds. In addition, C-H⋯O contacts are observed.

Monodispersed Ag2Se nanocubes and faceted nanocrystals have been synthesized by hexadecylamine (HDA) induced thermolysis of [(PPh3)3Ag2(SeC{O}Ph)2] in a mixture of TOP (tri-n-octyl phosphine) and HDA in the temperature range 95-180 degrees C.
