background: l1 retrotransposons are the most active mobile dna elements in human genome. unregulated l1 retrotransposition may have deleterious effect by disrupting vital genes and inducing genomic instabilities. therefore, human cells control l1 elements by silencing their activities through epigenetic mechanisms. it has been shown that cell division and heavy metals stimulate the frequency of...

the human papillomavirus l1 major capsid protein (hpv l1), the basis of the current vaccines, self-assembles into virus-like particles (vlps). herein, we describe the expression and purification of recombinant hpv16 l1 in e. coli system. the l1 protein was generated in a fused form using an inducible expression system. the recombinant gst-l1 fusion protein migrated as a 82 kda protein in sds-pa...

let a be a banach algebra and e be a banach a-bimodule then s = a  e, the l1-direct sum of a and e becomes a module extension banach algebra when equipped with the algebras product (a; x):(a′; x′) = (aa′; a:x′ + x:a′). in this paper, we investigate △-amenability for these banach algebras and we show that for discrete inverse semigroup s with the set of idempotents es, the module extension bana...

this empirical study reports on a cross-linguistic analysis of the overarching issue of l1 lexicalization regarding two (non)-interventionist approaches to vocabulary teaching. participants were seventy four juniors at the islamic azad university, roudehen branch in tehran. the investigation pursued (i) the impact of the provided (non)-interventionist treatments on both sets of (non)-lexicalize...

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...

background: cervical cancer has been shown to be highly associated with human papillomavirus (hpv) infection. the viral oncogenes e6 and e7 are constantly expressed by the tumor cells and are therefore potent targets for therapeutic genetic vaccination. in the present study, it was investigated the potential effect of hpv-16 e6, e7 and l1 co-administration to activate specific cytotoxic t lymph...

abstract background ulcerative colitis (uc) is characterized by recurrent episodes of inflammation limited to the mucosal layer of the colon. calprotectin is a zinc and calcium binding protein derived from neutrophils and monocytes. it is easily detectable in tissue samples, body fluids, and stools, which makes it a potentially valuable marker of inflammation. the aim of the current study is to...
