NaHCO3-Buffered Lidocaine Gel for Outpatient Rigid Cystoscopy in Men.

Purpose: The purpose of this study was to explore the effect of NaHCO3-buffered lidocaine gel as a topical anesthetic agent for pain relief for rigid cystoscopy.

Design: Prospective randomized controlled trial.

Methods: ASA I-II male patients undergoing rigid cystoscopy randomly received 10 mL 2% Carbocaine lidocaine gel with 1 mL 0.

Fine mapping of a dominant thermo-sensitive genic male sterility gene (BntsMs) in rapeseed (Brassica napus) with AFLP- and Brassica rapa-derived PCR markers.

A new thermo-sensitive dominant genic male sterility (TSDGMS) line of Brassica napus was found and mapped in this paper. Our result will greatly accelerate the map-based cloning of the BntsMs gene. TE5A is a thermo-sensitive dominant genic male sterility line originating from spontaneous mutation of the inbred line TE5 in Brassica napus and provides a promising system for the development of hybrid cultivars.

Carcinoembryonic antigen interacts with TGF-{beta} receptor and inhibits TGF-{beta} signaling in colorectal cancers.

As a tumor marker for colorectal cancers, carcinoembryonic antigen (CEA) enhances the metastatic potential of cancer cells. CEA functions as an intercellular adhesion molecule and is upregulated in a wide variety of human cancers. However, the molecular mechanisms by which CEA mediates metastasis remain to be understood.
