A case of a perfluoro-n-octane leakage into the orbital cavity after corneoscleral suture, scleral buckling and pars plana vitrectomy in an eye with perforating injury after trauma is reported for the first time. A previously healthy 39-year-old man was sent for ophthalmic evaluation one day after
The synthesis and assembly properties of a new water-soluble deep-cavity cavitand are discussed. For a homologous series of alkanes, the host can form a range of approximately isoenergetic 1:1, 2:1, and 2:2 complexes. As a result of this 'confluence' of binding and assembly the host displays an
We employ molecular dynamics simulations of n-octane near a layered graphene surface to study the related phenomena of solvation, density fluctuations, wettability, and structure and dynamics of n-octane molecules in the inhomogeneous interfacial environment. That solvation in bulk n-octane displays
P450 family 4 fatty acid ω-hydroxylases preferentially oxygenate primary C-H bonds over adjacent, energetically favored secondary C-H bonds, but the mechanism explaining this intriguing preference is unclear. To this end, the structure of rabbit P450 4B1 complexed with its substrate octane was
OBJECTIVE
To describe the clinical and histopathologic characteristics of inflammatory deposits occurring within intermediate duration postoperative perfluoro-n-octane (PFO) for inferior retinal detachment repair.
METHODS
Prospective interventional case series of consecutive patients with inferior
The properties of penicillin acylase from E. coli solubilized by hydrated reversed micelles of Aerozol OT (AOT) in octane were studied. The catalytic activity dependence on the hydration degree, a parameter which determines the size of the micelle inner cavity, represents a curve with three optima,
The properties of penicillin acylase from E. coli solubilized by hydrated reversed micelles (RM) of Aerosol OT in octane were studied. The dependence of catalytic activity on the hydration degree, a parameter which determines the size of the micelle inner cavity, has a curve with three optima, each
Evaluation of published methods reveals that existing methods for saliva sampling do not address the physical-chemical attributes of volatile organic compounds (VOCs). This study describes and presents evidence for adopting in situ sampling of salivary VOCs directly from the oral cavity using a
A sensor based on a mid-IR pulsed quantum cascade laser (QCL) and off-axis cavity enhanced absorption spectroscopy (OA-CEAS) has been developed for highly sensitive concentration measurements of carbon monoxide (CO) in a rapid compression machine. The duty cycle and the pulse repetition rate of the
The liquid-phase adsorption of n-alkanes (from n-octane (C8) solvent) with different chain lengths was carried out over three metal-organic frameworks (MOFs), viz., metal-azolate framework-6 (MAF-6), copper-benzenetricarboxylate (Cu-BTC), and iron-benzenetricarboxylate (MIL-100(Fe)), and a
Identifications of 5 odorants selected to be nontrigeminal stimuli were compared using retronasal and oral-cavity-only (OCO) air-phase presentations, with OCO produced by both exhalation through the mouth and a nose clip that closed the nostrils. Nine identifiers were available on each trial; 1 or 2
Using ultracentrifugation, the systems of reversed micelles of aerosol OT in octane containing solubilized protein (alpha-chymotrypsin, lysozyme, trypsin, egg albumin, alcohol dehydrogenase from horse liver and gamma-globulin) were studied. The changes in the sedimentation coefficients of reversed
The present study investigated the separation of bicyclic β-amino acids with bicyclo[2.2.2]octane, bicyclo[3.1.1]heptane and cyclopenta[d][1,2]oxazole core structures by capillary electrophoresis using native cyclodextrins as well as neutral and charged derivatives as chiral selectors. The amino
Based on rotational dynamics measurements carried out with isomorphic co-crystals formed by halogen-bonding (XB) between tritylacetylene halides (TrX) and diazabicyclo[2.2.2]octane (dabco), we were able to distinguish the sources of the enthalpic and entropic components in the rotational free energy
OBJECTIVE
To improve the surface visibility of perfluoroperhydrophenanthrene, we added various percentages of perfluoro-n-octane.
METHODS
Twenty New Zealand white rabbit eyes underwent gas vitrectomy. One milliliter of balanced salt solution was injected into each Group 1 eye as control.
