Study Protocol of Cardiac Rehabilitation for Acute Myocardial Infarction From the JROAD/JROAD-DPC Database - JROAD-CR.

Although cardiac rehabilitation (CR) has been reported to be effective for improving the prognosis of acute myocardial infarction (AMI), more patients must participate in CR during admission and as outpatients. Factors contributing to, and countermeasures against, the low CR participation rate need to be identified. Here we describe the protocol for a study designed to evaluate the effectiveness and problems of CR for AMI from the Japanese Registry of All Cardiac and Vascular Diseases (JROAD) and the JROAD-Japanese Diagnosis Procedure Combination system (JROAD-DPC) database.

Protocol for a multicentre, prospective observational cohort study in Japan: association among hospital-acquired disability, regular exercise and long-term care dependency in older patients after cardiac surgery.

Introduction: Cardiac surgery for older patients, postoperative functional decline and the need for long-term care have received increasing attention as essential outcomes in recent years. Therefore, prevention of functional decline and long-term care dependency after cardiac surgery are important; however, our current understanding of postoperative functional trajectory and effects of postoperative regular exercise on long-term functional decline and long-term care dependency is limited. Therefore, we will conduct a multicentre, prospective cohort study to (1) examine the effect of hospital-acquired disability on long-term functional decline and long-term care dependency and (2) investigate the favourable effect of postoperative regular exercise on long-term functional decline and long-term care dependency in older patients after cardiac surgery.

Two new steroid sulfates from a cheilostome bryozoan, sp.

Two new steroid sulfates and were obtained from a lipophilic extract of an undescribed bryozoan species in the genus . The structures of compounds and were elucidated by spectroscopic methods and chemical modifications. Steroids and exhibited moderate cytotoxicity at IC 54 and 30 µM, respectively, against NBT-T2 cells.

Difference in electromyographic activity between the trapezius muscle and other neck accessory muscles under an increase in inspiratory resistive loading in the supine position.

The activity of the trapezius muscle is reportedly higher than that of other neck accessory muscles under a condition of increased inspiratory pressure in the standing position. The present study aimed to compare the activity of the trapezius muscle with those of the scalene and sternocleidomastoid muscles under a condition of increased inspiratory pressure in the supine position. This study included 40 subjects, and the muscle activity was measured using surface electromyography.

Structure and Dynamics of the Methane-Propane van der Waals Complex.

Microwave transitions in the region 7-26 GHz were measured for the methane-propane van der Waals complex. The nearly free internal rotation of methane within the complex gives rise to three states that do not relax even in a 5 K supersonic expansion. Eighteen lines have been assigned to the lowest state and are well fitted to a semirigid rotor model, with rotational constants A = 7553.
