Safety of repeated low-level red-light therapy for children with myopia.

Backgroud: To investigate the safety of repetitive low-level red-light therapy (RLRLT) in children with myopia.

Methods: Children with myopia were assigned to the RLRL and control groups. Axial length (AL) and spherical equivalent refraction (SER) were followed up at 3-, 6-, and 12-month.

A rabbit pulmonary vein myocyte isolation method based on simultaneous heart and pulmonary vein perfusion.

Myocytes in the pulmonary veins (PV) play a pivotal role in the development of paroxysmal atrial fibrillation (AF). It is therefore important to understand physiological characteristics of these cells. Studies on these cells are, however, markedly impeded by the fact that single PV myocytes are very difficult to obtain due to lack of effective isolation methods.
