Structure and electrochemical properties of (μ-O)Mn(iii,iii) and (μ-O)Mn(iii,iv) complexes supported by pyridine-, quinoline-, isoquinoline- and quinoxaline-based tetranitrogen ligands.

Seven new bis(μ-oxo)dimanganese complexes with Mn(iii,iii) or Mn(iii,iv) oxidation states were prepared using quinoline- and isoquinoline-based tetraamine ligands. The structures of the ligands include ethylenediamine, trans-1,2-cyclohexanediamine and tripodal amine, bearing two or three nitrogen-containing heteroaromatics. Regardless of the skeleton and number of aliphatic nitrogen atoms in the ligands, quinoline complexes stabilize the Mn(iii,iii) oxidation state, whereas, isoquinoline ligands afford Mn(iii,iv) complexes.

Quinoline-based fluorescent zinc sensors with enhanced fluorescence intensity, Zn/Cd selectivity and metal binding affinity by conformational restriction.

Two cyclohexanediamine-based tetrakisquinoline derivatives, N,N,N',N'-tetrakis(2-quinolylmethyl)-trans-1,2-cyclohexanediamine (TQDACH) and N,N,N',N'-tetrakis(1-isoquinolylmethyl)-trans-1,2-cyclohexanediamine (1-isoTQDACH), have been prepared and their zinc-induced fluorescent response was investigated. In DMF-H2O (1 : 1) solution, TQDACH exhibits increase of fluorescence at 455 nm in the presence of 1 eq. of zinc ion (λ(ex) = 317 nm, φ = 0.

[Case of suspected malignant hyperthermia following local infiltration anesthesia].

A 49-year-old man with no past history of malignant hyperthermia (MH) and scheduled for hernia repair was suspected of MH after local infiltration anesthesia at other hospital. Although intravenous diazepam was not effective for increased body temperature, tachycardia, and convulsion, dantrolene was effective for these signs. However, blood test showed no abnormal finding.

Long-term stability of conservative orthodontic treatment in a patient with rheumatoid arthritis and severe condylar resorption.

Rheumatoid arthritis is a chronic inflammatory condition that can result in progressive destruction of the articular surfaces of the joints, including the temporomandibular joint. The purpose of this article is to report the conservative correction of a Class II malocclusion in a woman with rheumatoid arthritis. The patient was 32 years 6 months old at the start of treatment.

[TURP syndrome with severe hyponatremia (98 mEq x l(-1)): a report of a case].

We report a case of transurethral resection of prostate (TURP) syndrome with severe hyponatremia (98 mEq x l(-1)). A relatively healthy 71-year-old man (167 cm and 61 kg) with benign prostatic hypertrophy was scheduled for transurethral resection of the prostate under general anesthesia. Ninety minutes after starting the operation, electrolyte analysis revealed a decrease in serum Na concentration (Na 98 mEq x l(-1), BE -6.

Adult Class III treatment using a J-hook headgear to the mandibular arch.

Objective: To evaluate the treatment effects of high-pull J-hook headgear on the lower dental arch in nongrowing Class III patients.

Materials And Methods: Fourteen nongrowing Class III patients having an Angle Class III malocclusion and ANB angle of less than 1.0 degree, were treated with high-pull J-hook headgear to the lower arch.

Nonextraction treatment of upper canine-premolar transposition in an adult patient.

This article reports the successful treatment of a unilateral maxillary canine and first premolar transposition without the extraction of the premolar in an adult patient. A female patient, 21 years and three months of age, had moderate crowding in the upper arch with complete transposition of the canine and first premolar. After distal movement of the upper molars with a lingual arch and headgear appliance, the upper left first premolar and canine were transposed.
