This paper aims at discovering and investigating the effect of l1 translation, l1 gloss andcontext on vocabulary learning on EFL Iranian learners. A total number of 120 EFL students inprivate English institutes in Sari participated in the present study. They were divided into twoproficiency groups and three learning conditions. In order to make a list of words unknown to thelearners the partici...

OBJECTIVE Programmed death-ligand 1 (PD-L1) was expressed in various tumors and antibodies targeting its receptor programmed cell death-1 (PD-1) are emerging cancer therapeutics. This study was designed to evaluate the expression of PD-L1 and its correlation with clinicopathologic features and clinical outcomes in ovarian clear cell carcinoma (OCCC). METHODS The PD-L1 expression was measured ...

abstract the role of l1 in second/foreign language learning has been the subject of much debate and controversy. this article reports on a piece of research carried out in a junior high school in isfahan, iran. this study was conducted to examine the effect of using translation from l1 to l2 on the improvement of efl learners' language accuracy. to fulfill the purpose of the study, 62 stud...

the importance and howness of language learning/ acquisition has been a great concern for decades. there are many factors that play important roles in this regard. this research compared the performance of native persian and english elementary students to see if there is any significant difference between the two groups and which type of collocation they performed better within the groups. for ...

The human papillomavirus (HPV) capsid consists of 360 copies of the major capsid protein, L1, arranged as 72 pentamers on a T=7 icosahedral lattice, with substoichiometric amounts of the minor capsid protein, L2. In order to understand the arrangement of L2 within the HPV virion, we have defined and biochemically characterized a domain of L2 that interacts with L1 pentamers. We utilized an in v...

The L1 adhesion molecule is a member of the immunoglobulin superfamily shared by neural and immune cells. In the nervous system L1 can mediate cell binding by a homophilic mechanism. To analyze its function on leukocytes we studied whether L1 could interact with integrins. Here we demonstrate that VLA-5, an RGD-specific fibronectin receptor on a wide variety of cell types, can bind to murine L1...

in this paper, we study l1 -solutions of the following two-direction poly-scale refinement equationwe prove that the vector space of all l1 -solutions of the above equation is at most one-dimensional andconsists of compactly supported functions of constant sign. we also show that any- l1 solution of the aboveequation is either positive or negative on its support under a special assumption. with...

In a very important recent study, Chen and colleagues describe that PD-L1 (B7-H1, CD274) is expressed on both malignant cells and infiltrating macrophages in a subset of aggressive B-cell lymphomas (1). The article highlights the possibilities of targeting the PD-1/PD-L1 pathway in these malignancies. Interactions between PD-1 on T cells and the ligand PD-L1 (B7-H1) control the induction and ma...
