Dead end (dnd) is a vertebrate-specific component of the germ plasm and germ-cell granules that is crucial for germ-cell development in zebrafish and mouse. Dnd counteracts the inhibitory function of miRNAs, thereby facilitating the expression of proteins such as Nanos and Tdrd7 in the germ cells. Here, we show that cis-acting elements within dnd mRNA and(More)
The incidence and mortality rate of Clostridium difficile infection have increased remarkably in both hospital and community settings during the last two decades. The growth of infection may be caused by multiple factors including inappropriate antibiotic usage, poor standards of environmental cleanliness, changes in infection control practices, large(More)
The identification of small RNA molecules and the elucidation of their functions in the cell enhanced our understanding of the mechanisms controlling gene expression at the posttranscriptional level. Here, we review findings concerning the role small RNA molecules play in the development of the germline in various organisms. In this context, microRNAs(More)
Single-cell migration is a key process in development, homeostasis, and disease. Nevertheless, the control over basic cellular mechanisms directing cells into motile behavior in vivo is largely unknown. Here, we report on the identification of a minimal set of parameters the regulation of which confers proper morphology and cell motility. Zebrafish(More)
BACKGROUND The incidence of nosocomial Staphylococcus aureus infection is increasing annually and becoming a true global challenge. The pattern of Staphylococcus aureus protein A (spa) types in different geographic regions is diverse. OBJECTIVES This study determined the prevalence of methicillin-resistant S. aureus and different spa types in S. aureus(More)
PURPOSE Pulmonary fibrosis is a potentially lethal inflammatory disease and there has been no effective medication for this progressive disease up to now. As a model, different therapeutic approaches have been applied for paraquat-induced pulmonary injury and fibrosis. Atorvastatin besides cholesterol-lowering effects possesses anti-inflammatory and(More)
BACKGROUND The development of drug delivery systems has improved the therapeutic and toxic properties of existing drugs in therapy. Microemulsion systems are novel vehicles for drug delivery, which have been developed in recent years. These systems are currently of interest to the pharmaceutical scientist because of their considerable potential to act as(More)
BACKGROUND Clostridium difficile infection (CDI) is major growing problem in hospitals and its high incidence has been reported in recent years. OBJECTIVES The aim of this study was to investigate the antimicrobial susceptibility patterns of C. difficile clinical isolates against antibiotics commonly used for treatment CDI in hospitalized patients.

In the present study, protective effect of Teucrium polium L. (Labiatae) extract on acetaminophen-induced hepatotoxicity was investigated in mice. Animals were divided into six groups, each group consist of 8 mice. Group one as the negative control group received normal saline, while group two received only crude extract of T. polium L. (500 mg/Kg) for five(More)
In micro-fluid systems, fluids are injected into extremely narrow polymer channels in small amounts such as micro-, nano-, or pico-liter scales. These channels themselves are embedded on tiny chips. Various specialized structures in the chips including pumps, valves, and channels allow the chips to accept different types of fluids to be entered the channel(More)
