Cloning of hemoglobin-α1 from half-smooth tongue sole (Cynoglossus semilaevis) and its expression under short-term hypoxia.

This study cloned the hemoglobin α1 from the marine teleost, the half-smooth tongue sole (Cynoglossus semilaevis), and then examined its expression under hypoxia exposure. The full-length of CsHb-α1 (594 bp) cDNA contains an open reading frame encoding 144 amino acids. Sequence analysis shows that the predicted CsHb-α1 amino acids shares high identities with that of other species.

Cloning and expression analysis of a long type peptidoglycan recognition protein (PGRP-L) from Xenopus tropicalis.

Peptidoglycan recognition proteins (PGRPs) are a family of pattern recognition receptors (PRRs) of the immune system, which bind and hydrolyze bacterial peptidoglycan. Here, a long type PGRP (PGRP-L) was first cloned in the lower vertebrate species Xenopus tropicalis (Xt). The XtPGRP-L possessed a conserved genomic structure with five exons and four introns.

[Surgical treatment of giant coronary artery aneurysm].

Objective: To discuss the clinical features and surgical treatments of giant coronary artery aneurysm (CAA).

Methods: From July 1996 to October 2004, 6 giant CAA patients were underwent surgery at Fuwai hospital. Three cases were underwent CAA resection, 2 concomitant coronary bypass, 3 reconstruction.
