The use of a supercooling refrigerator improves the preservation of organ grafts.

Current medical transplantation confronts major problems such as the shortage of donors and geographical restrictions that inhibit efficient utilization of finite donor organs within their storage lives. To overcome these issues, expanding organ preservation time has become a major concern. We investigated whether a strategy which best preserves organ grafts can be achieved by the use of a newly developed refrigerating chamber, which is capable of establishing a supercooled and unfrozen state stably by generating an electrostatic field in its inside.

Prognostic and clinical significance of newly acquired complete right bundle branch block in Japan Airline pilots.

Objective: The purpose of this study was to evaluate the prognostic and clinical significance of newly acquired complete right bundle branch block (CRBBB) in airline pilots.

Patients: This study included pilots with acquired CRBBB, identified from a group of over 2,700 Japan Airline pilots. When the pilots applied for employment, a past medical history, physical examination, electrocardiogram, and chest radiograph were obtained.

Stress-induced hyperphosphorylation of tau in the mouse brain.

We previously showed that starvation causes reversible hyperphosphorylation of tau in the mouse brain. To explore possible involvement of stress in tau hyperphosphorylation quantitative analysis of phosphorylated tau in four brain regions of mice subjected to cold water stress (CWS) was made by immunoblot analyses using phosphorylation-dependent antibodies directed to eight sites on tau known to be hyperphosphorylated in the brain of Alzheimer's disease (AD) patients. Ser199, Ser202/Thr205, Thr231/Ser235 were hyperphosphorylated 20 and 40 min after CWS.
