A bidentate iridium carbene complex, Ir(κC,O-L1)(COD), has been synthesised which contains a strongly electron donating carbene ligand that is functionalised by a cis-spanning phenolate group. This complex acts as a precursor to effective magnetisation transfer catalysts which form after reaction with H2 and a suitable two electron donor. In solvents such as benzene, containing pyridine, they a...

programmed cell death-1 (pd-1) and its ligands, pd-l1 and pd-l2, have been regarded as important immune system regulatory molecules. the aberrant expression of the molecules has been related to several autoimmune disorders. this study is aimed to assess the mrna expression level of pd-1, pd-l1, and pd-l2 molecules in the peripheral blood mononuclear mells (pbmcs) from multiple sclerosis (ms) pa...

Adult second language (L2) learners are faced with a particular challenge relative to child L2 learners—adults arrive at the language learning situation with a fully-formed and ingrained first language (L1) system in place. As a result, adult learners are particularly influenced by the transfer of information from L1 to L2 (e.g., MacWhinney, 2005). Although transfer assists learning in some dom...

Collocations are one of the areas generally considered problematic for EFL learners. Iranian learners of English like other EFL learners face various problems in producing oral collocations.  An analysis of learners' spoken interlanguage both indicates the scope of the problem and the necessity to spend more time and energy by learners on mastering collocations. The present study specifically f...
