Repair of massive bone loss remains a challenge to the orthopaedic surgeons. Autologous and allogenic bone grafts are choice for bone reconstructive surgery, but limited availability, risks of transmittable diseases and inconsistent clinical performances have prompted the development of tissue engineering. In the present work, the bone regeneration potential of nanohydroxyapatite/chitosan composite scaffolds were compared with pure chitosan scaffolds when implanted into segmental bone defects in rabbits.

Previous studies suggest that dietary advanced glycation end products (AGEs) can cause oxidative stress in liver. We aim to study the effects of dietary AGEs on liver health and their possible role in the pathogenesis of NASH.

High mechanical performance nitrile-butadiene rubber (NBR) with light color was fabricated by the method of in situ formation of zinc disorbate (ZDS) or magnesium disorbate (MDS). The in situ formed ZDS and its polymerization via internal mixing was confirmed by X-ray diffaraction. The mechanical properties, ageing resistance, morphology and the dynamic mechanical analysis were fully studied.

Methods: Retrieved clinical trials comparing percutaneous radiofrequency ablation with RES for small hepatocarcinoma published from 1990 to 2010. A meta-analysis was conducted to estimate overall survival and disease free survival.
Coherent optical single-carrier frequency-division-multiplexing (CO-SCFDM) is a promising candidate for future high-speed long-haul optical fiber transmission system. Being a modified form of coherent optical orthogonal frequency division multiplexing (CO-OFDM), the CO-SCFDM can inherit the advantages such as low computation complexity and high flexibility, while suffers less nonlinear impairment due to much lower peak-to-average power ratio (PAPR). In this paper, we experimentally demonstrate 1.

The lengths of the complete mitochondrial DNA sequences of the three species were 16990, 16964, and 16773 bp, respectively. Each of the three mitochondrial DNA genomes included 13 protein-coding genes, 22 tRNA, two rRNA, one O(L)R, and one control region.

This study identifies a transcytotic pathway in LGACs regulated by Rab11a for polymeric immunoglobulin receptor (pIgR) and dIgA. EGFP-tagged Rab11a expressed in primary LGACs labeled a unique membrane compartment of comparable localization to endogenous Rab11a beneath the apical plasma membrane.

Oxidative stress plays a critical role in the pathogenesis of non-alcoholic steatohepatitis (NASH). This study was designed to investigate whether hemoglobin is expressed in hepatocytes and how it is related to oxidative stress in NASH patients.

Potassium ions are required for gastric acid secretion. Several potassium channels have been implicated in providing K(+) at the apical membrane of parietal cells. In examining the mRNA expression levels between gastric mucosa and liver tissue, KCNJ15 stood out as the most highly specific K(+) channel in the gastric mucosa.

This study was aimed to investigate the expression and clinical significance of CDX1, CDX2 and CDX4 genes in acute lymphocytic leukemia (ALL). Expressions of CDX1, CDX2, and CDX4 in 51 adult acute lymphocytic leukemia patients and 14 healthy subjects were detected by reverse transcription polymerase chain reaction (RT-PCR). The results indicated that CDX1, CDX2 and CDX4 were not expressed in 14 healthy persons and 15 CR ALL patients, the positive expression rate of CDX2 gene in de novo ALL patients was 60.

Background/aims: Hepatocellular carcinoma (HCC) is one of the most lethal and prevalent cancers in the human population. Despite its significance, there is only limited understanding of pathological mechanisms and therapeutic options. Talin1, a focal adhesion complex protein that is required for cell adhesion and motility, regulates integrin interactions with extracellular matrix (ECM).

Radixin, the dominant ezrin-radixin-moesin (ERM) protein in hepatocytes, has two important binding domains: an NH(2)-terminal region that binds to plasma membrane and a COOH-terminal region that binds to F-actin after a conformational activation by phosphorylation at Thr564. The present studies were undertaken to investigate the cellular changes in expression of radixin in WIF-B cells and to assess radixin distribution and its influence on cell polarity. We used a recombinant adenoviral expression system encoding radixin wild-type and Thr564 mutants fused to cyan fluorescent protein (CFP), as well as conventional immunostaining procedures.

Ezrin is an important membrane/actin cytoskeleton linker protein, especially in epithelia. Ezrin has two important binding domains: an NH(2)-terminal region that binds to plasma membrane and a COOH-terminal region that binds to F-actin only after a conformational activation by phosphorylation at Thr567 of ezrin. The present experiments were undertaken to investigate the detailed cellular changes in the time course of expression of ezrin-T567 mutants (nonphosphorylatable T567A and permanent phospho-mimic T567D) in parietal cells and to assess ezrin distribution and its influence on the elaborate membrane recruitment processes of these cells.
