Reproduction is a key process, which highly influences the economic efficiency of pig production. Traditional quantitative genetics plays a very important role in animal breeding. Selection for increased number of piglets born has been employed in pigs with only limited success because of the low heritability, the late expression in life and the sex-limited nature of reproductive traits.

The Altai Paleozoic orogenic belt of Xinjiang Autonomous Rejoin is geologically wellknown both domestic and abroad by the intensive development of low-pressure metamorphism and granitic magmatism. Within pelitic metamorphic rocks, even though sillimanite is well developed and the low-pressure minerals like andalusite and cordeirite etc. are quite common, the assemblage of garnet and staurolite is more important.

Soil erosion by wind, as a natural disaster haunts on dry lands, not only degrades soil productivity but also often results in dust blizzard weather. It may cause pollutions of air and water, damages of highway and railway, wear and tear of buildings and machinery and harmfulness in health of people and animals. Therefore, to combat wind erosion means improving the environment for people to live and work, means heightening the living standard of the local people, and means promoting productive forces. But China has a vast land where probably occur wind erosion disasters, the arid, semiarid and subhumid areas of the temperate zone all are potentially hit by wind erosion. To control wind erosion in China is a very arduous task. More difficult is to achieve recognizable effectiveness with lowest cost.

Narrow Line Seyfert 1s (NLS1s, including high luminosity quasars with similar properties) are very important extrema of type Ⅰ AGNs. The unusualness of NLS1s is very useful to test the viabilities of AGNs models and thus provide a new way probing into AGN phenomena. The ratio of Fe to α-element (e. g., O, Ne, Mg...), Fe/α, can serve as an excellent indicator for constraining the ages of star-forming systems.

Cardiac hypertrophy is one of adaptive responses of the heart to a variety of pathological stimuli, including hypertension, myocardial infarction, congenital heart disease, heart valvula disease, and perturbations in sarcomeric function due to altered expression or mutations of contractile proteins. Increase in wall tension and hormonal stimuli are thought to directly activate various membrane-bound receptors and signal transduction cascade within cardiomyocytes resulting in the activation of immediate early genes and responsive genes such as c-jun, c-fos, c-myc, egr-1, ANF, BNP. Then the expression of construction proteins such as MLC-1, skeletal α-actin was unregulated.

The vast majority of follicles undergo a degenerative process in reproductive life. Apoptotic cell death is the fundamental mechanism in response to follicular atresia. Moreover, the apoptosis of granulose cells is implicated in directly mediating atretic process. Multiple studies have confirmed that the apoptotic process of GCs is not only related to apoptotic genes, but triggered by cytokines related to reproduction and Caspases family.
