Proteomics and bioinformatics analysis of altered protein expression in the placental villous tissue from early recurrent miscarriage patients.

Introduction: Recurrent miscarriage (RM) affects 5% of women, it has an adverse emotional impact on women. Because of the complexities of early development, the mechanism of recurrent miscarriage is still unclear. We hypothesized that abnormal placenta leads to early recurrent miscarriage (ERM).

[Significance of carbonic anhydrase IX protein expression in molecular subtyping of breast cancers].

Objective: To study the expression of carbonic anhydrase (CA) IX and its significance in molecular subtyping of breast carcinomas. METHODL MaxVision immunohistochemical staining was used to examine the expression of ER, PR, HER2, CK5/6, EGFR, and CA IX in 117 cases of breast invasive ductal carcinomas.

Results: The patients' age ranged from 25 to 71 years (mean 49.

Preparation of superhydrophobic cross-linked syndiotactic 1,2-polybutadiene membranes by electrospinning.

In this study, syndiotactic 1,2-polybutadiene (s-PB)/azobisisobutyronitrile (AIBN) membranes were prepared via electrospinning. The obtained membranes were intensively investigated by contact angle analyzer, differential scanning calorimetry (DSC) and environmental scanning electron microscope (ESEM). With increasing the concentration of spinning solution, the obtained membranes were changed from hydrophobic to surperhydrophobic and the contact angle (CA) as high as 157 degrees at higher s-PB concentration.

Preparation and morphology of polyethylene/clay nanocomposite with novel MgCl2/montmorillonite (MMT) bi-supported Ziegler-Natta catalyst.

In the present article, the spherical and high activity TiCl4/MgCI2/MMT intercalated catalyst was successfully prepared. The active centers of obtained catalyst well dispersed in the MMT through electron probe micro-analysis (EPMA). The d-spacing of MMT was broadened from 0.

[SSR linkage map construction and QTL mapping for leaf area in maize].

Maize (Zea mays L.) leaf is the main organ for photosynthesis. The area of leaves (especially the ear-leaf and the two leaves above and below the ear-leaf) plays a vital role in dry matter accumulation and grain yield.
