The papillomaviruses (PVs) are a family of viruses infecting several mammalian and nonmammalian species that cause cervical cancer in humans. The evolutionary history of the PVs as it associated with a wide range of host species is not well understood. Incongruities between the phylogenetic trees of various viral genes as well as between these genes and the host phylogenies suggest historical v...

OBJECTIVE Coinhibitory signals mediated via programmed death 1 (PD-1) receptor play a critical role in downregulating immune responses and in maintaining peripheral tolerance. Programmed death 1 ligand 1 (PD-L1), the interacting ligand for PD-1, widely expressed in many cell types, acts as a tissue-specific negative regulator of pathogenic T-cell responses. We investigated the protective potent...

Ru(II) complexes with chelating ligands, 4',5'-ethylenedithiotetrathiafulvenyl[4,5-f][1,10]phenanthroline (L1), 1,3-dithiole-2-thiono[4,5-f][1,10]phenanthroline (L2), and 1,3-dithiole-2-ono[4,5-f][1,10]phenanthroline (L3), have been prepared and their structural, electrochemical, and photophysical properties investigated. Density functional theory (DFT) calculations indicate that the highest oc...

This study presents cross-sectional data on adjectival agreement in second-language (L2) learners of Norwegian with four different first languages (L1s). The target language has full noun phrase between article, adjective and noun, the source represent conditions, similar to or from language. Sixteen participated study, their oral production was analysed individually. Two hypotheses were propos...

Recently the studies concentrating on computer assistant language learning (CALL) has been growing in numbers as they offer many advantages that couldn't otherwise be provided by a traditional classroom setting. In addition to popular computer-assisted pronunciation teaching (CAPT) systems, computer-assisted prosody training system is another branch of CALL (Computer assistant language learning...

the acquisition of argument structures has been studied by a variety of second language acquisition scholars within the past two decades (atay, 2010; can, 2009; chay, 2006, & kras, 2007, among others). in the present study, ‘predicate’ as the most substantial element of a sentence is investigated. there are three english verb-types which seem to be more problematic for persian efl learners:...

In this paper, we nd the relationships between module contractibility of aBanach algebra and its ideals. We also prove that module contractibility ofa Banach algebra is equivalent to module contractibility of its module uniti-zation. Finally, we show that when a maximal group homomorphic image ofan inverse semigroup S with the set of idempotents E is nite, the moduleprojective tensor product l1...
