BACKGROUND/OBJECTIVES: The aim of this study was to investigate the effect of Berberis vulgaris (BV) juice consumption on insulin homeostasis, glycemic profiles of patients with benign breast disease (BBD). SUBJECTS/METHODS: This parallel design, triple-blind, randomized and placebo controlled clinical trial was conducted on 85 eligible women diagnosed with BBD who recruited from Nour-Nejat hos...

DFT-M062X quantum chemical computations on the Ala3H(+)·nH2O (n up to 37) complexes have been performed to model for hydration effects on the molecular properties of protonated trialanine. Following simple rules to arrange water molecules around the peptide, geometry optimization allows us to find four minima corresponding to the unfolded extended (β) and polyproline II (PPII) conformations. Th...

Preliminary observations [Sykes & Lowry (1980) J. Endocrinol. 85, 42P-43P] had suggested that the major hypothalamic somatoliberin (growth-hormone-releasing factor) was a larger peptide than the other characterized hypothalamic factors, with an elution position on Sephadex G-50 between those of neurophysin and corticotropin. The present paper reports the isolation and preliminary characterizati...

This paper describes two approaches for the synthesis of a crossed alkene-bridged mimic of the thioether ring system of the nisin Z DE-fragment. The first approach comprised the stepwise total synthesis featuring a cross metathesis and a macrolactamization on a solid support followed by a ring-closing metathesis in solution. Via this route the title compound was obtained in an overall yield of ...

background and objectives: baculovirus can be used as a vector in gene delivery system. viral envelope of baculovirus would display expressed protein/peptide and it could render as a potential vaccine delivery system. in this regard, the gene coding for a subunit of shiga toxin (stxa) from escherichia coli ( e. coli ) strain was cloned in a baculovirus expression system. stxa subunit has the ab...

b ackground: l eishmania is an intracellular parasite infecting humans and many wild and domestic animals. recent studies have suggested an important role for cytotoxic t cells against leishmania . peptide-based vaccines targeting short sequences derived from known immunogenic proteins have been shown to elicit cellular immune responses against disparate pathogens. m ethods: we predicted four h...

Ankylosing spondylitis (AS) is a chronic inflammatory arthritis of unknown origin. Its autoimmune origin has been suggested but never proven. Several reports have implicated Klebsiella pneumoniae as a triggering or perpetuating factor in AS; however, its role in the disease pathogenesis remains debated. Moreover, despite extensive investigations, a biomarker for AS has not yet been identified. ...
