PURPOSE To describe the morphologic features of Fuchs corneal dystrophy and compare them with those of bullous keratopathy. METHODS This was an observational case series. The study group consisted of 32 corneal buttons with a diagnosis of Fuchs dystrophy and the comparison group consisted of 22 corneal buttons with bullous keratopathy. Morphologic analysis was performed of corneal buttons fro...

A new indene-based ligand featuring pendant phosphine sulfide and amine donor fragments has been developed; Rh(I) coordinates to the neutral form of the ligand in a kappa2-[N,S] fashion, while the anionic form of the ligand binds Rh(I) and Mn(I) in kappa2-[C,S] and eta5 modes, respectively.

In previous studies (1, 2, 3) one of us (L.) has reported experiments which are concerned with the oxidation of sulfur in the cystine molecule. It was demonstrated that if deamination of cystine be prevented by “blocking” the amino group (as in phenyluraminocystine (1) or dibenzoylcystine (3) ), the sulfur of the molecule was not oxidized normally and was excreted in the urine in large part in ...

Influence of acetate-C/NO3(-)-N/S(2-) ratio to the functional microbial community during the denitrifying sulfide removal process is poorly understood. Here, phylogenetic and functional bacterial community for elemental sulfur (S(0)) recovery and nitrate (NO3(-)) removal were investigated with the switched S(2-)/NO3(-) molar ratio ranged from 5/2 to 5/9. Optimized S(2-)/NO3(-) ratio was evaluat...

An electrically bistable device has been fabricated based on poly(N-vinylcarbazole) (PVK)-silver sulfide (Ag2S) composite films using a simple spin-coating method. Current-voltage (I-V) characteristics of the as-fabricated devices exhibit a typical electrical bistability and negative differential resistance (NDR) effect. The NDR effect can be tuned by varying the positive charging voltage and t...

All-solid-state secondary batteries that employ inorganic solid electrolytes are desirable because they are potentially safer than conventional batteries. The ionic conductivities of solid electrolytes are currently attracting great attention. In addition to the conductivity, the mechanical properties of solid electrolytes are important for improving the energy density and cycle performance. Ho...

A new chemiluminescence method is proposed for the determination of sulfide in seawater based on the chemiluminescence reaction between sulfide and an acidic permanganate solution. 3-Cyclohexylaminopropanesulfonic acid was used as a chemiluminescence enhancer. By use of this method, 1-150 µM of sulfide could be determined in artificial seawater. The limit of detection was 0.17 µM sulfide. We in...
