Hypermethylation and transcription of 14-3-3σ gene in sporadic breast carcinogenesis;

BACKGROUND&AIM: To investigate the expression of early growth response gene_1(Egr_1gene)and PTEN in esophageal epitheliosis and carcinogenesis,and the relation with the development of esophageal carcinoma.

Prospective study on expressions of cyclin D1 and Rb and significance in carcinogenesis of the esophagus

Study on the Evolution Process and the Drive Mechanism of Urban Residential Space in Zhengzhou City;

Both oasis development and desertification and both human advance but desert retreat and desertadvance but human retreat existed in the evolution processes of the ecological environment in the arid areas innorthwest China during the historical periods.

From an angle of technological development, this paper analyzes the causes and evolution process of forgery, and put forwards relevant countermeasures.

The investigation of deformation process and anomalous characteristics for arch dam and its abutments built on complex rock foundation;

The deformation process of tube cold rolling on double-set multi-roll mill is studied and the calculation formulation of deformation for once roll,elongation coefficient, relative reduction of wall thickness per rolling schedule are deduced.

The deformation process of strips trimming is introduced.

Valence electron structure of γ-Fe unit-cell bearing alloy atoms and its influence on phase transformation of the alloy structural steel;

Various stages of phase transformation and crystallization of thepowder were studied systematically by chemical analysis , thermal analysis,x-ray diffraction and transmis-sion electron microscopy.

The radiation of high temperature particle with phase transformation is encountered in numerous technologically important applications such as target diagnostics and investigation, temperature measurements of flame, remote sensing and suppression of forest fires, plasma spraying and many others.
