T HE SENSITIVITY OF LYMPHOCYTES to irradiation provides a rationale for the use of extracorporeal irradiation (ECI ) of the circulating blood to destroy lymphocytes selectively.

These studies1 established the basic feasibility and effe...

To the Editor: Comparisons of the Vitros ECi thyroid-stimulating hormone (TSH) method with the AxSym (1 ), Immulite (1, 2), Elecsys (2 ), and ADVIA Centaur (2 ) have shown an unexplained progressive negative bias ,0.2 mIU/L, a phenomenon that we have also observed (Fig. 1A). To investigate the bias, we diluted the TSH International Reference Preparation 80/558 (predominately pituitary TSH) and ...

Although several studies have estimated the associations between mortality or morbidity and extreme temperatures in terms of relative risk, few studies have investigated the risk of emergency transport attributable to the whole temperature range nationwide.We acquired data on daily emergency ambulance dispatches in all 47 prefectures of Japan from 2007 to 2010. We examined the relationship betw...
