Epicatechin (Epi), a flavanol found in foods such as dark chocolate has previously been shown to enhance memory formation in our model system, operant conditioning of aerial respiration in Lymnaea. In those experiments snails were trained in Epi. Here we ask whether snails exposed to Epi before training, during the consolidation period immediately following training, or 1 h after training would...
Granulins (grns) or epithelins (epis) are peptides with molecular masses of approx. 6 kDa that modulate the growth of cells. The precursor for the grns/epis, which might itself be biologically active, is a secreted glycoprotein containing multiple repeats of the grn/epi motif. Grn/epi mRNA occurs widely in vivo, particularly in tissues rich in epithelial and haematopoietic cells. To understand ...
We examined the interaction of complement component C3 with surface molecules on Trypanosoma cruzi. Five- to six-fold more C3 was bound to epimastigotes (Epi) than to metacyclic trypomastigotes (CMT) of strain M88. Epi and CMT were surface iodinated, then incubated in C8-deficient serum, and detergent lysates were applied to anti-C3 antibody that had been coupled to Sepharose. We found that 9.2...
Two-layer metallic sheets have wide applications in various industries due to their superlative characteristics. This paper presents analytical model to investigate the formability of two-layer sheets based on Marciniak and Kuckzinsky (M-K) method using Barlat and Lian non-quadratic yield criterion. FEM simulation is also performed to calculate the forming limits based on bifurcation theory. Fo...
High speed and absence of a precise control over pressure distribution confine sheet Electromagnetic Forming into a die to simple shapes having shallow depth. It is possible to reach a higher depth by using a convex punch instead of a concave die. In this study, sheet Electromagnetic Forming on a punch and sheet Electromagnetic Forming into a die are investigated. The electromagnetic part of th...
امروزه موضوع حفاظت از محیط زیست و جلوگیری از تخریب آن به عنوان یکی از مهم ترین چالش های فراروی جامعه جهانی مطرح شده و پایداری زیست محیطی یکی از موضوعات مهم مطرح شده در طی چند دهه اخیر در سطح بین الملل می باشد.شاخص های زیست محیطی متعددی از سوی سازمان ملل متحد و دانشگاه ها مطرح شده است که از کارایی و کارامدی لازم برای نظارت بر فرایندهای تخریب محیط زیست کشورهای گوناگون برخوردار می باشند. این رسال...
CXCL12-CXCR4 signaling controls multiple physiological processes and its dysregulation is associated with cancers and inflammatory diseases. To discover as-yet-unknown endogenous ligands of CXCR4, we screened a blood-derived peptide library for inhibitors of CXCR4-tropic HIV-1 strains. This approach identified a 16 amino acid fragment of serum albumin as an effective and highly specific CXCR4 a...
the present study is a research which explores the relationship between introversion/extroversion and the use of vocabulary learning strategies. the participants were 80 male and female efl students of university of sistan and baluchestan who had studied efl at the university for at least two years and were randomly selected. the participants were selected after excluding those who got l scores...
PURPOSE To assess the diagnostic performance of readout-segmented echo-planar diffusion tensor imaging (DTI based on rs-EPI) for breast cancer and to determine the correlation between the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values obtained from DTI based on rs-EPI with prognostic markers of invasive breast cancer. MATERIALS AND METHODS This retrospective study ...
Antioxidant protection of low density lipoprotein by procyanidins: structure/activity relationships.
The antioxidant activity of catechins and oligomeric procyanidins against low density lipoproteins peroxidation was studied by means of three distinct methods: cis-parinaric acid fluorescence decay, conjugated-dienes detection, and oxygen consumption. A relationship between the radical trapping efficiency of procyanidins and their structure was investigated. The results indicated that: (i) inte...
