Frame Technology was introduced during the early 1980’s as an approach to providing significant levels of improvement in software productivity through adaptive reuse. However, despite the claims of order of magnitude improvements and reuse levels of 90%, this technology does not appear to have acquired a corresponding level of popularity, appearing to loose out to the more recent technologies o...

Contact force (CF) sensing technology allows real-time monitoring during catheter ablation for atrial fibrillation (AF). However, the effect of CF sensing technology on procedural parameters and clinical outcomes still needs clarification. Because of the inconsistent results thus far in this area, we performed a meta-analysis to determine whether CF sensing technology can improve procedural par...

The prognostic value of the platelet-to-lymphocyte ratio (PLR) in non-small cell lung cancer (NSCLC) remains controversial. We therefore conducted a meta-analysis of published studies to determine the prognostic value of PLR in NSCLC. A systematic search was performed in PubMed, Web of Science and Embase for relevant studies. The data and characteristics of each study were extracted, and the ha...

Background: Gastrointestinal (GI) malignancies are the most common cancers and account for nearly half of all cancer-related deaths in Iran. There was a strong association between human papillomavirus (HPV) infection and urogenital cancers, in particular the cervix. However, there is no clear causal relationship in all types of cancers, including gastrointestinal cancers. Therefore, the present...

Technology improves people’s life and makes business more viable than ever before, especially eleisure and e-business. Many Small and Medium Enterprises (SMEs) which might not have enough budget for establishing their IT (Information Technology) department can today easily benefit from the use of technologies like Web technology, Web applications and their underlying supporting platforms and me...

background and aims: infertility is one of the most important conditions in reproductive system and there is no reliable estimates for global prevalence of infertility. therefore, knowing the prevalence of infertility is important and can be effective in decision making. methods: we systematically reviewed all published papers in medline database and scopus (1988–2010). univariate and multivari...

BACKGROUND Whether increased expression of the tumor suppressor protein p53 indicates a p53 gene mutation in hepatocellular carcinoma (HCC) remains unclear. We conducted a meta-analysis to determine whether p53 protein overexpression detected by immunohistochemistry (IHC) offers a diagnostic prediction for p53 gene mutations in HCC patients. METHODS Systematic literature searches were conduct...

BACKGROUND AND OBJECTIVES The possible association between psoriasis and celiac disease (CD) has long been observed, but epidemiologic studies attempting to characterize this association have yielded inconclusive results. This meta-analysis was conducted with the aims to summarize all available data. METHODS We conducted a systematic review and meta-analysis of observational studies that repo...

We report a photoresist offset method using gray-scale technology to counteract the effect of aspect ratio dependent etching (ARDE), achieving controlled etch depths across a range of aspect ratios. Previously, we have reported the first fabrication of a deep phase Fresnel lens (PFL) in silicon through the use of gray-scale technology. As each PFL ridge becomes thinner at larger radii of the PF...
