Unusual photoreaction of triquinacene within self-assembled hosts.

Triquinacene is a concave tricyclic hydrocarbon with diverse photoreactivity. In the cavity of an electron-accepting molecular host, triquinacene was specifically photooxidized at the peripheral allylic position into an alcohol, 1-hydroxytriquinacene, via guest-to-host electron transfer. The unusual reactivity stems from the extremely electron-deficient triazine panel ligand of the host cage, which allows the cage to function as a good electron acceptor. Thus, self-assembled coordination cages can serve not only as molecular-sized reaction vessels but also function electronically as redox media. Dissolved molecular oxygen is indispensable for the photoreaction and immediately traps a photogenerated radical.

Cage-catalyzed Knoevenagel condensation under neutral conditions in water.

A cationic coordination cage dramatically accelerates the Knoevenagel condensation of aromatic aldehydes in water under neutral conditions. The addition of a nucleophile to the aldehyde to generate anionic intermediates seems to be facilitated by the cationic environment of the cavity. The products are ejected from the cage as a result of the host-guest size discrepancy. As a result, the condensation is promoted by a catalytic amount of the cage.

[The effect of videophone system for diabetic homecare patients on glycemic control].

It is imperative to develop a novel care approach and low-cost health care system for diabetic patients.Therefore, we conducted an intervention study to clarify how effectively a videophone system could be used in the life style guidance focusing on diet for the diabetic patients cared at home.For the period of 3 months, diabetic patients were communicated with a medical professional staff bi-directionally through a videophone-based communication system for 30 minutes once a week.During the 30-minute intervention, the medical staff checked the list with the change in weight, drug adherence and an exercise habit.We encouraged a diabetic patient to eat properly based on the diet record.The 3-month intervention program resulted in a significant decrease in BW(p<0.001 ), BMI(p<0.001 ), and the average HbA1c level(p<0.005 ).In conclusion, we showed a 3-month intensive communication result using a multimodal videophone system, which revealed a significant decrease in the body weight, BMI and the average HbA1c level.This once a week ICT communication might be useful as an auxiliary therapy to help change a bad daily habit to a good daily habit for a diabetic homecare patient.

[The Support System for Diabetic Patients at Home with Bi-Directional IT Communication].

The present study analyzed the effects of bi-directional IT communication on the purpose of preventing diabetes progression and to reduce a caregiver burden. Diabetic patients were informed of the nature and purpose of the study before giving their voluntary consents to participate in the study. For the period of 12 weeks, a diabetic patient and his caregiver were communicated with a nurse through the TV telephone for 30 minutes once a week. Medical staff checked the list of weight change, compliance check, exercise habit, and attached pictures of the plate with a diabetic patient through the TV telephone in real time. We encouraged a diabetic patient to eat properly based on the diet record. The 12-week TV telephone communication resulted in the body weight decrease and HbA1c. There was a consciousness change about their daily eating habit. In the present study, the 12-week TV telephone communication once a week might be useful as an auxiliary therapy for changing a bad daily habit to a good daily habit for a diabetic patient at home.
