Narciclasine (NCS) is an Amaryllidaceae alkaloid isolated from Narcissus tazetta bulbs. Its phytotoxic effects on plant growth were examined in lettuce (Lactuca sativa L.) seedlings. Results showed that high concentrations (0.5–5 μM) of NCS restricted the growth of lettuce roots in a dose-dependent manner. In NCS-treated lettuce seedlings, the following(More)
Genetic diversity is essential for persistence of animal populations over both the short- and long-term. Previous studies suggest that genetic diversity may decrease with population decline due to genetic drift or inbreeding of small populations. For oscillating populations, there are some studies on the relationship between population density and genetic(More)
BACKGROUND The long-term association between the status of the false lumen and poor patient outcomes in acute aortic dissection (AAD) remains unclear. This systematic review and meta-analysis investigated whether the status of the false lumen was a predictor of poor long-term survival in AAD. METHODS AND RESULTS Eleven cohort studies (2924 participants)(More)
OBJECTIVE To analyze the clinical significance of ocular vestibular evoked myogenic potentials (oVEMP) and cervical vestibular evoked myogenic potentials (cVEMP) in primary unilateral benign paroxysmal positional vertigo (BPPV). METHOD Fifty-two patients with unilateral primary BPPV (BPPV group) and 38 normal subjects (control group) received ocular(More)
