گونه endl. eucalyptus occidentalis از درختان مهم و تندرشد در زراعت چوب و بهره برداری اقتصادی در صنایع چرم سازی، کاغذسازی، تهیه اسانس و داروسازی است. در این تحقیق، ریزازدیادی این گونه به طریق کشت جوانه در محیط کشت ms و gd بررسی شد. بر روی نمونه ها، تیمار سترون سازی، استقرار، شاخه زایی و ریشه زایی اعمال شد. آزمایش فاکتوریل در قالب طرح پایه کاملاًً تصادفی به اجرا درآمد. تیمار سترون سازی مورد استفاده...
Single, teased fiber recordings were made from the decentralized right cervical vagus nerve (hyponodal) of the rat. A total of 67 afferent fibers that responded to gastric distension (GD) were studied: 9 fibers were stimulated by phasic balloon GD, 58 by more natural fluid GD. All balloon GD-responsive fibers had resting activity (3.1 imp/s), and 57/58 fluid GD responsive fibers had resting act...
Glycoprotein D (gD) is a structural component of the herpes simplex virus (HSV) envelope which is essential for virus entry into host cells. Chinese hamster ovary (CHO-K1) cells are one of the few cell types which are nonpermissive for the entry of many HSV strains. However, when these cells are transformed with the gene for the herpesvirus entry mediator (HVEM), the resulting cells, CHO-HVEM12...
Graves' disease (GD) is associated with T cell infiltration, but the mechanism for lymphocyte trafficking has remained uncertain. We reported previously that fibroblasts from patients with GD express IL-16, a CD4-specific chemoattractant, and RANTES, a C-C chemokine, in response to GD-specific IgG (GD-IgG). We unexpectedly found that these responses result from a functional interaction between ...
Nephrogenic systemic fibrosis (NSF) is a fibrosing disorder that may develop in patients who have advanced reduction in renal function. A causal relation between gadolinium (Gd(3+))-based contrast agents (Gd-CA) and NSF is probable and is supported by the accumulating data in the literature. From those data, the prevalence of NSF is seen to be significantly higher after exposure to gadodiamide ...
BACKGROUND The newly developed magnetic-resonance-imaging (MRI) hepatocyte-specific contrast agent, gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA), has different excretion pathways from the conventional MRI contrast agent, gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA). In this study, we compare the enhancement effect of the liver and renal parenchyma betwee...
Several cell membrane proteins have been identified as herpes simplex virus (HSV) entry mediators (Hve). HveA (formerly HVEM) is a member of the tumor necrosis factor receptor family, whereas the poliovirus receptor-related proteins 1 and 2 (PRR1 and PRR2, renamed HveC and HveB) belong to the immunoglobulin superfamily. Here we show that a truncated form of HveC directly binds to HSV glycoprote...
Extracellular gadolinium contrast agents (Gd-CA) are either linear or macrocyclic chelates available as ionic or non-ionic preparations. The molecular structure whether cyclic or linear and ionicity determines the stability of Gd-CA. Linear chelates are flexible open chains which do not offer a strong binding to Gd(3+). In contrast, the macrocyclic chelates offer a strong binding to Gd(3+) by t...
We present an X-ray absorption spectroscopy study of the local structures of Gd(DTPA)(2)(-) and Gd(DOTA)(-) complexes in the crystalline state (at room and low temperatures) and in aqueous solutions exhibiting various pH values (0.15-7) at different temperatures (25-90 degrees C). Using X-ray absorption fine structure (XAFS) analysis procedures and ab initio multiple scattering calculations of ...
Gd(3+) blocks stretch-activated channels and suppresses stretch-induced arrhythmias. We used whole cell voltage clamp to examine whether effects on Na(+) channels might contribute to the antiarrhythmic efficacy of Gd(3+). Gd(3+) inhibited Na(+) current (I(Na)) in rabbit ventricle (IC(50) = 48 microM at -35 mV, holding potential -120 mV), and block increased at more negative test potentials. Gd(...
