Discrimination of Brugada syndrome patients from individuals with the saddle-back type ST-segment elevation using a marker of the standard 12-lead electrocardiography.

Background: In the clinical situation, the saddle-back (S-B) type is more frequently detected than the coved type. In the present study, the discrimination of Brugada syndrome from the S-B type individuals using a marker of the standard 12-lead electrocardiography (ECG) was attempted.

Methods And Results: The study group consisted of 55 individuals with the S-B type in whom pilsicainide provocation test (PLC test) was carried out.

Effect of phytate-removal and deamidation of soybean proteins on calcium absorption in the in situ rats.

Soybean proteins were deamidated by cation-exchange resins after phytate, the inhibitor for calcium absorption from the small intestine, was removed in order to provide the enhancement function of calcium absorption to soybean proteins. About 92% of the phosphorus was removed from the soybean proteins by anion-exchange-resin treatment, indicating that most of the phytate was removed. About 70% of the acid amide was deamidated by cation-exchange-resin treatment, and phytate-removed and deamidated soybean proteins (PrDS) having high calcium binding properties were obtained.
