Recently, it is considered that Mg is a kind ofnatural antagonist of calcium (Ca). Mg has some effects onthe smooth muscles of the bronchial and pulmonary arteries,and to relax the spasm of them. Therefore, there may exista close relation between Mg and cor pulmonale caused bychronic obstructive pulmonay desease (COPD).展开更多

We report here a case of cor-triatriatum dexter who presented at 3 days of life with tachypnea and did not respond to antibiotics. Echocardiography revealed ostium secundum atrial septal defect (ASD) with right to left flow, intact interventricular septum (IVS), severe tricuspid regurgitation with pulmonary arterial hypertension and a membranous structure dividing right atrium into 2 halves with good biventricular function. The patient improved with sildenafil and anti-failure medication. This case of cor-triatriatum dexter presenting with pulmonary hypertension, tricuspid regurgitation and ASD added to the new spectrum of cor-triatriatum dexter.展开更多

To improve their cold tolerance, plants often upregulate the expression of some cold-related genes. In this study, a cold-regulated (COR) gene was isolated from Vitis amurensis and designated as VaCOR. RT-PCR analysis demonstrated that VaCOR was expressed at high levels in the roots, stems, leaves, and petioles under low temperature, but it was not detected under normal temperatures. Further analysis revealed that salinity and the application of exogenous abscisic acid and salicylic acid significantly induced VaCOR transcription, with apparent differences in its expression in different organs. The data also showed that COR gene expression was higher in cold-resistant wild V. amurensis than in cold-sensitive Vitis vinifera “Manicure Finger” under low temperature. These results suggest that the VaCOR gene in V. amurensis grapes is involved in multiple stresses and plays a central role in stress-induced and stress-tolerance.展开更多
