introduction: cystic fibrosis (cf) is a common genetic disorder in white populations with an autosomal recessive pattern, caused by mutations in the cftr gene. the frequency of more than 1950 various mutations reported in the cftr gene significantly varies in different populations. ∆f508 is a common mutation in exon 10, which is first addressed in the molecular analysis of the disease. other ex...

based on the controversial beliefs among l2 teachers about effective corrective feedback (cf) strategies, recast and prompts as 2 kinds of cf have drawn the attention of l2 researchers(e.g., braidi, 2002; iwashita, 2003; loewen & philp, 2006; panova & lyster, 2002; sheen, 2004). despite these numbers of studies, debate continues to exist about their usefulness as a cf technique. whereas...

A primary tumor can create a premetastatic niche in distant organs to facilitate the development of metastasis. The mechanism by which tumor cells communicate with host cells to develop premetastatic niches is unclear. We focused on the role of microRNA (miR) signaling in promoting metastasis. Here, we identified miR-203 as a signaling molecule between tumors and monocytes in metastatic colorec...

Biometric based authentication protocols for multi-server architectures have gained momentum in recent times due to advancements in wireless technologies and associated constraints. Lu et al. recently proposed a robust biometric based authentication with key agreement protocol for a multi-server environment using smart cards. They claimed that their protocol is efficient and resistant to promin...

The development of laryngeal squamous cell carcinoma (LSCC) is a multistep process involving multiple factors. MicroRNAs, a group of important negative regulators of gene expression, have also been confirmed to be involved in the LSCC pathogenesis. In the present study, we compared the expression of nine selected microRNAs in the LSCC tissues and adjacent nontumor tissues. We found that the exp...

Bladder cancer is often associated with recurrence and progression to invasive metastatic disease that have palliative therapeutic options. The use of traditional chemotherapeutic agents for bladder cancer management often suffers from toxicity and resistance concerns. This emphasizes the need for development of safer, natural, nontoxic compounds as chemotherapeutic/chemopreventive agents. Curc...

this study is a typological description of written formative feedback in an efl context in iran. twenty m.a. students of tefl participated in the study. they were required to summarize a scholarly article in each session on which the instructor would provide written corrective feedback (cf). written formative comments were extracted, coded, and categorized into various types, such as asking for...
