background: despite major advances in assisted reproductive techniques, the implantation rates remain relatively low. some studies have demonstrated that intrauterine infusion of granulocyte colony stimulating factor (g-csf) improves implantation in infertile women. objective: to assess the g-csf effects on ivf outcomes in women with normal endometrial thickness. materials and methods : in this...

Carbon nanotubes (CNTs), nowadays, are one of the important nanomaterials that can be produce with different methods such as chemical vapor deposition (CVD). Growing of CNTs via CVD method can be influenced by several operating parameters that can affect their quality and quantity. In this article, the effects of inlet gas mixture temperature on CNT’s local growth rate, total production, and le...

BACKGROUND The nisin-controlled gene expression system NICE of Lactococcus lactis is one of the most widely used expression systems in Gram-positive bacteria. Despite its widespread use, no optimization of the culture conditions and nisin induction has been carried out to obtain maximum yields. As a model system induced production of lysostaphin, an antibacterial protein (mainly against Staphyl...
