Inversion of circularly polarized luminescence by electric current flow during transition.

The development of chiral compounds exhibiting circularly polarized luminescence (CPL) has advanced remarkably in recent years. Designing CPL-active compounds requires an understanding of the electric transition dipole moment () and the magnetic transition dipole moment () in the excited state. However, while the direction and magnitude of can, to some extent, be visually inferred from chemical structures, remains elusive, posing challenges for direct predictions based on structural information.

Percutaneous pulmonary debanding for an infant complicated by spontaneously closing muscular ventricular septal defect: A case report and in vitro study.

Pulmonary artery banding (PAB) is a standard operation for various congenital heart defects complicated by pulmonary hypertension (PH) and judged unsuitable for primary intracardiac repair. We report successful percutaneous pulmonary artery debanding in a baby complicated by muscular ventricular septal defect (VSD), that was initially large and multiple, but closed spontaneously later. The 5-month-old boy was referred to our hospital on day 3, diagnosed as having aortic coarctation (CoA), with multiple muscular VSDs and severe PH.

Incidence of Persistent Left Superior Vena Cava in the Normal Population and in Patients with Congenital Heart Diseases Detected Using Echocardiography.

Reports on the incidence of persistent left superior vena cava (PLSVC) in the normal population are limited to studies involving pacemaker implantation candidates and cadavers. The incidence in patients with congenital heart diseases (CHDs) is estimated to be higher than that in the normal population; however, the details are unclear. To investigate the incidence of PLSVC in the normal population and in patients with CHDs, subjects were examined prospectively using echocardiography.

High Toxoplasma antibody prevalence among inhabitants in Jakarta, Indonesia.

We examined IgG antibody to Toxoplasma in sera from 1,693 inhabitants aged 20-85 years in Jakarta. The seroprevalence rate was 70%, without any significant differences between males (71%) and females (69%). Some epidemiological factors contributing to the high prevalences of antibody to Toxoplasma in inhabitants of urban areas in Indonesia were discussed.

Evidence for antigen production in muscles by dengue and Japanese encephalitis DNA vaccines and a relation to their immunogenicity in mice.

This study demonstrated viral antigen production in muscle tissues following inoculation with DNA vaccines and examined its relation to antibody induction in mice using the flavivirus system. To achieve detectable levels of antigen production, we used a needle-free jet injector and examined 10% homogenate of quadriceps muscle for viral antigens in a sandwich enzyme-linked immunosorbent assay. We compared DNA vaccines against dengue type 1 (designated pcD1ME), dengue type 2 (pcD2ME) and Japanese encephalitis (pcJEME).

Immunogenicity of a Japanese encephalitis DNA vaccine candidate in cynomolgus monkeys.

A Japanese encephalitis (JE) vaccine candidate encoding JE virus premembrane (prM) and envelope (E) genes, designated pNJEME, was evaluated for safety and immunogenicity in non-human primate, cynomolgus monkeys. pNJEME was constructed using a vector (pNGVL4a) designed to address some of the safety concerns of DNA vaccine. In two different experiments, two immunizations with 300 microg of pNJEME by intramuscular (i.

Simultaneous immunization with DNA and protein vaccines against Japanese encephalitis or dengue synergistically increases their own abilities to induce neutralizing antibody in mice.

Gene-based and protein-based vaccines are two distinct types of vaccines. In this report, we examined if combined use of DNA and protein vaccines would increase their own abilities to induce neutralizing antibody in murine models for Japanese encephalitis (JE) or dengue type 2 (DEN2). DNA vaccines for JE (pcJEME) or DEN2 (pcD2ME) were inoculated intramuscularly, and protein vaccines consisting of subviral extracellular particles (EPs) containing JE (JEEP) or DEN2 (D2EP) virus antigens were inoculated subcutaneously with Freund's adjuvant.

[Percutaneous transluminal angioplasty of the subclavian artery].

We reported a case of subclavian artery stenosis successfully treated by percutaneous transluminal angioplasty (PTA). He suffered from left arm claudication and proximal subclavian artery stenosis. The stenosis and symptoms disappeared soon after PTA.

Natural killer activity of peripheral blood lymphocytes and its relation to histopathological factors of lung cancer.

This investigation was intended to determine whether the natural killer (NK) activity of peripheral blood lymphocytes (PBL) correlated with the histopathological factor, which is thought to be a result of a balance between tumor aggression and host resistance. The NK activity of PBL from 60 patients with lung cancer was measured by the lysis of 51Cr-labelled K562 target cells. The activity was significantly decreased with advancing stages of the disease, and inversely correlated with increased immunosuppressive substance levels of the serum.
