Cyclic hexamers consisting of a 4-octyl, 4-octyloxy and 4-(2-ethylhexyloxy)triphenylamine unit were synthesized via Buchwald-Hartwig cross coupling reaction using A-A, B-B type monomers in order to avoid the formation other cyclic oligomers such as pentamer heptamer. Unlike different size oligomers, all we examined showed clear cold crystallization 165-240°C DSC thermograms. Resulting character...

OBJECTIVES To compare octyl-cyanoacrylate tissue adhesive (OCT) with the standard suture technique for the closure of laparoscopic port sites. METHODS This was a randomized clinical trial of 40 patients. All participants had 2 lower abdominal ports, with one port closed using OCT while the opposite port was closed with 4-0 monocryl suture. An evaluation of the wound was performed 2 weeks to 4...

The aim of this study was to determine the local and systemic effects of adipose-derived stem cells (ADSCs) as a component of topical skin adhesive in an animal artificial wound closure model. In presented study the cosmetic effects, histological analysis, mechanical properties, and cell migration have been assessed to evaluate the usefulness of ADSCs as supporting factor for octyl blend cyanoa...

The benzimidazolone part of the mol-ecule of the title compound, C(15)H(21)N(3)O(3), is almost planar (r.m.s. deviation = 0.007 Å) with its mean plane aligned at a dihedral angle of 10.4 (3)° with respect to the mean plane of the nitro substituent. In the crystal, two mol-ecules are disposed about a center of inversion, generating an N-H⋯O hydrogen-bonded cyclic dimer with R(2) (2)(8) graph-set...

The movement of cucurbit[7]uril (CB[7]) driven by alpha-cyclodextrin (alpha-CD) is investigated by various experimental techniques including NMR, ESI-MS, UV-vis, and ITC. CB[7] can form stable pseudorotaxanes with N-methyl-N'-octyl-4,4'-bipyridinium (MVO2+) and N,N'-dioctyl-4,4'-bipyridinium (OV2+) dication in aqueous solution. CB[7] shuttles between the octyl and bipyridinium moieties in MVO2+...

In this study, N,N-Dimethyl-N-Octyl chitosan was synthesized. Nanoparticles containing insulin were prepared using PEC method and were statistically optimized using the Box-Behnken response surface methodology. The independent factors were considered to be the insulin concentration, concentration and pH of the polymer solution, while the dependent factors were characterized as the size, zeta po...

Inhibitors of aflatoxin production of aflatoxigenic fungi are useful for preventing aflatoxin contamination in crops. As methyl syringate weakly inhibits aflatoxin production, aflatoxin production inhibitory activities of additional alkyl syringates with alkyl chains from ethyl to octyl were examined. Inhibitory activity toward aflatoxin production of Aspergillus flavus became stronger as the l...

We report a case of intrarenal pseudoaneurysm of the right kidney after percutaneous nephrolithotomy (PCNL) in supine position. Diagnosis was established by angiotomography with a 3-D reconstruction. Treatment was successfully achieved by endovascular occlusion using N-butyl-2-cyanoacrylate.

BACKGROUND A few single case reports and only one clinical series have been published so far about the use of N-butyl-2-cyanoacrylate in the treatment of urinary fistulas persisting after conventional urinary drainage. CASE PRESENTATION We treated five patients with a mean age of 59.2 years presenting iatrogenic urinary fistulas which persisted following conventional drainage manouvres. There...

n-Octyl beta-D-thioglucopyranoside, a new non-ionic detergent, was synthesized. Properties, and applicability to membrane proteins, of this detergent were investigated. The detergent was easily removed by dialysis. The solubilizing power of this detergent for Escherichia coli membrane proteins was similar to that of n-octyl beta-D-glucopyranoside, which has been widely used in membrane biochemi...
