Tertiary hospital nurses' ethical sensitivity and its influencing factors: A cross-sectional study.

Background: High ethical sensitivity positively affects the quality of nursing care; nevertheless, Chinese nurses' ethical sensitivity and the factors influencing it have not been described.

Research Objectives: The purpose of this study was to describe ethical sensitivity and to explore factors influencing it among Chinese-registered nurses, to help nursing administrators improve nurses' ethical sensitivity, build harmony between nurses and patients, and promote the patients' health.

Research Design: This was a descriptive, cross-sectional study.

Structural Determination of a Filamentous Chaperone to Fabricate Electronically Conductive Metalloprotein Nanowires.

The transfer of electrons through protein complexes is central to cellular respiration. Exploiting proteins for charge transfer in a controllable fashion has the potential to revolutionize the integration of biological systems and electronic devices. Here we characterize the structure of an ultrastable protein filament and engineer the filament subunits to create electronically conductive nanowires under aqueous conditions.

Discovery of perturbation gene targets via free text metadata mining in Gene Expression Omnibus.

There exists over 2.5 million publicly available gene expression samples across 101,000 data series in NCBI's Gene Expression Omnibus (GEO) database. Due to the lack of the use of standardised ontology terms in GEO's free text metadata to annotate the experimental type and sample type, this database remains difficult to harness computationally without significant manual intervention.

Viral Etiology Relationship between Human Papillomavirus and Human Breast Cancer and Target of Gene Therapy.

Objective: To explore the viral etiology of human breast cancer to determine whether there are novel molecular targets for gene therapy of breast cancer and provide evidence for the research of gene therapy and vaccine development for breast cancer.

Methods: PCR was used to screen HPV16 and HPV18 oncogenes E6 and E7 in the SKBR3 cell line and in 76 paraffin embedded breast cancer tissue samples. RNA interference was used to knock down the expression of HPV18 E6 and E7 in SKBR3 cells, then the changes in the expression of cell-cycle related proteins, cell viability, colony formation, metastasis, and cell cycle progression were determined.

Clinical values of elevated serum cytokeratin-18 levels in hepatitis: a meta-analysis.

Background: As an important intermediate filament protein within liver cells, cytokeratin-18 (CK-18) has been confirmed as a potential indicator in various hepatitis progressions.

Objectives: We sought to clarify the connection between serum CK-18 levels and hepatitis pathogenesis in the present meta-analysis.

Materials And Methods: With the application of various computerized databases, including PubMed, Embase, Cochrane Library, Google Scholar, Web of Science, China BioMedicine (CBM), China National Knowledge Infrastructure (CNKI), published papers that assessed the relationship between serum CK-18 levels and hepatitis were obtained.

MicroRNA expression profile of bromocriptine-resistant prolactinomas.

MicroRNAs (miRNA) have been implicated in the resistance of tumors to chemotherapy. However, little is known about miRNA expression in bromocriptine-resistant prolactinomas. In this study, 23 prolactinoma samples were classified as bromocriptine-sensitive or -resistant according to the clinical definition of bromocriptine resistance, and their miRNA expression profiles were determined using Solexa sequencing.

Natural history of postoperative nonfunctioning pituitary adenomas: a systematic review and meta-analysis.

Objective: Previous studies attempting to define the natural history of postoperative nonfunctioning pituitary adenomas (pNFPAs) were somewhat limited by selection bias and/or small numbers and/or lack of consistency among the study findings. The aim of this study was to scrutinize the literature in order to analyze the natural history of pNFPAs.

Methods: Electronic database including MEDLINE, PubMed and Cochrane CENTRAL were searched.
