[Heritability of body weight and fork length for Oncorhynchus masou masou].

Body weight and body length have been considered as the most important production traits for the fish genetic improvement. For cold-water fish, body length was usually substituted by fork length. In order to estimate the heritability of body weight and fork length of the sixth generation Oncorhynchus masou masou, which was introduced into China, the method of unbalanced nest design and an artificial insemination technigue were used.

2-methoxycinnamaldehyde from Cinnamomum cassia reduces rat myocardial ischemia and reperfusion injury in vivo due to HO-1 induction.

Ethnopharmacological Relevance: Cinnamomum cassia Blume has been used as a traditional Chinese herbal medicine for alleviation of fever, inflammation, chronic bronchitis, and to improve blood circulation.

Aim Of The Study: We addressed whether 2-methoxycinnamaldehyde (2-MCA), one of active ingredients of Cinnamomum cassia, reduces vascular cell adhesion molecule-1 (VCAM-1) expression in tumor necrosis factor-alpha (TNF-α)-activated endothelial cells and protects ischemia/reperfusion (I/R)-injury due to heme oxygenase (HO)-1 induction.

Materials And Methods: Adult male rats were subjected to 30 min of ischemia by occlusion of the left anterior descending coronary artery followed by 24h of reperfusion.

Palmatine from Coptidis rhizoma reduces ischemia-reperfusion-mediated acute myocardial injury in the rat.

The aim of the present study was to evaluate the protective effect of palmatine, one of active ingredients of Coptidis rhizoma, against myocardial ischemia-reperfusion (I/R) injury is due to its antioxidant and anti-inflammatory action. Adult male rats were subjected to 30 min of ischemia and 6 or 24h of reperfusion. Rats were randomized to receive vehicle or palmatine 1h before reperfusion.

[The genetic diversity of diploid and triploid crucian carp from six populations in Heilongjiang River System].

Twelve microsatellite markers from silver crucian carp were used to investigate the genetic structuring of the diploid and triploid crucian carp from six natural populations in Heilongjiang River System. In the six populations, the number of average allele (A) is from 5.8 to 6.

Ultra-structural changes and developmental potential of porcine oocytes following vitrification.

This study evaluated the effects of exposure and/or vitrification of porcine metaphase II (MII) oocytes on their in vitro viability and ultra-structural changes with two experiments. Experiment 1 examined the effect of vitrified oocytes on microtubule localization, mitochondrial morphology, chromosome organization and the developmental rate in IVF control and vitrified oocytes. Oocytes matured for 44 h were subjected to IVF (IVF control).
