Reciprocal communication between the immune system and the neuroendocrine system is mediated via a common chemical language of shared ligands and receptors. The neuropeptide substance P (SP) has been implicated as a mediator of immunomodulation. The evidence for substance P receptors on human lymphocytes is, however, controversial. The aims of the present study are to investigate substance P re...
تشریح ، مشتق گیری و کاربردهایی از تغییرات فرمول های ثابت برای توابع حقیقی مقدار، بررسی های ما را به ویژگی هایی از فضاهای باناخ خاص از توابع لیپشیتز در فضاهای متریک و نیمگروه های تعریف شده بر روی (پیش) دوگانهای آنها ، هدایت می کند. فضاهایی از اندازه ها به طور چگال و فضاهای متریک به طور پیوسته، در این پیش دوگانها نشانده می شوند. تحت شرایطی یک نیمگروه از تبدیلات لیپشیتز در فضای متریک بتوی نیمگروه...
ااصلاح‌کننده‌های آلی غالبا جهت بهبود خصوصیات خاک از جمله شیمیایی و تغذیه‌ای استفاده می‌شوند. هدف از این پژوهش مطالعه اثر ورمی‌کمپوست دامی بر پارامتر‌های هم‌دما‌های جذب، نیاز استاندارد (SPR) و ظرفیت بافری فسفر (PBC) در مقایسه با سه نوع ترکیبات آلی دیگر شامل کود مرغی، کود دامی و تفاله انگور است. بدین منظور 5 نمونه خاک با 2 درصد از ترکیبات آلی ذکر شده به مدت یک ماه در انکوباتور نگهداری شدند و سپس ...
BACKGROUND This study aimed to assess whether Chinese men who have sex with men (MSM) had a significantly elevated prevalence of psychiatric disorders compared to urban males in China. METHODS 807 MSM were recruited using a respondent-driven sampling (RDS) method in urban area of northeast China. Psychiatric disorders were assessed employing the Composite International Diagnostic Interview (C...
The surface plasmon resonance (SPR) biosensor method has emerged as a very flexible and powerful approach for detecting a wide diversity of biomolecular interactions. SPR monitors molecular interactions in real time and provides significant advantages over optical or calorimetric methods for systems with strong binding and low spectroscopic signals or reaction heats. The SPR method simultaneous...
Previous analyses of the uteroglobin gene promoter revealed a GT1 box which is also found in the SV40 enhancer. The GT1 element in the context of the uteroglobin promoter is active in Ishikawa cells, a human endometrial cell line, but not in HeLa cells. Here we report the cloning by recognition site screening of two factors (SPR-1 and SPR-2) which bind to this GT1 motif. SPR-1 and SPR-2 are hom...
The potential of feeding a blend of 3 strains of Bacillus subtilis (Sporulin; SPR), to control Salmonella (SAL) was evaluated in broilers challenged with a strain of Salmonella Heidelberg (SH) isolated in Brazil . A total of 288 broilers were allocated to 6 treatments of 4 replicates of 12 birds each . Groups were T1) Non-challenged (NC), T2) NC fed 250 g of SPR/ton, T3) NC fed 500 g of SPR/ton...
Based on silicon-on-insulator (SOI) rib waveguide with large cross-section, a micro integrated surface plasmon resonance (SPR) biochemical sensor platform is proposed. SPR is excited at the deeply etched facet of the bend waveguide by the guiding mode and a bimetallic configuration is employed. With the advantages of SOI rib waveguide and the silicon microfabrication technology, an array of the...
The online combination of surface plasmon resonance (SPR) with mass spectrometry (MS) could be beneficial for accurately acquiring molecular interaction data simultaneously with their structural information at high throughputs. In this work, a novel SPR-MS interface was developed using a dielectric barrier discharge ionization (DBDI) source. The DBDI source was placed in front of the MS inlet, ...
Preterm birth is the leading cause of perinatal morbidity and mortality. Fetal fibronectin (fFN), a glycoprotein in the extracellular matrix of the amniotic membranes, is the most powerful biomarker for predicting the risk of preterm birth. Biosensors using the surface plasmon resonance (SPR) response are potentially useful in quantitatively measuring molecules. We established a standard calibr...
