Occurrence and Prevention of Delayed Autonomous Selfing in (Lamiaceae).

Delayed autonomous selfing (DAS) provides reproductive assurance under conditions of pollinator and/or pollen-limitation. Few plant species have been investigated to determine if DAS is terminated when a flower is sufficiently pollinated by a pollen vector, thereby saving plant resources for other purposes. We examined this possibility in bumblebee-pollinated .

Correlation between lymphatic endothelial markers and lymph node status or N-staging of colorectal cancer.

Background: The purpose of this study is to examine the expression levels of lymphatic endothelial markers in colorectal cancer and to explore the correlation between the expression levels of markers and lymph node status.

Methods: Forty-seven paired fresh tumor tissues and para-cancerous tissues were collected from colorectal cancer patients who received surgical treatment between August 2015 and March 2016 in Cancer Hospital, Chinese Academy of Medical Sciences. Real-time quantitative PCR (RTQ-PCR) was used to check the expression levels of LYVE-1, VEGFR-3, Podoplanin, and Prox-1 in tumor and para-cancerous tissues.
