This study aimed to investigate the magnetic resonance (MR) signal enhancement ratio (ER) of contrast-enhanced MR angiography (CE-MRA) in normal rats with gadobenate dimeglumine (Gd-BOPTA) using a clinical 3T scanner and an extremity coil. The relaxivities of Gd-BOPTA with saline only and with 4.5% human serum albumin (HSA) were also measured. Compared with Gadolinium diethylenetriaminepentaace...
We have investigated the physicochemical and paramagnetic properties of the new gadolinium complexes of N-(pyrid-2-yl-methyl)-ethylenediamine-N,N,N-triacetic acid (Gd-PEDTA) and N-tris(2-aminoethyl)amine-N,N,N,N,N,N+hexaacetic acid(Gd-TTAHA). The relaxivities as well as the thermodynamic and conditional stability constants of these complexes with respect to the physiological relevance were dete...
BACKGROUND This study aimed to evaluate the risk of depression and other cardiovascular comorbidities in Graves' disease (GD) patients in Asia. METHODS The study patients were all newly diagnosed with GD [International Classification of Disease, 9th Revision, Clinical Modification (ICD-9-CM) 242.0] from January 1998 to December 2008. Patients aged <20 years or those with preexisting mental di...
سابقه و هدف: در این تحقیق، دو عامل گادولینیوم ـ هماتوپورفیرین و ترکیب گادولینیوم با آنتی بادی تک دودمانی c595 به عنوان عوامل کنتراست اختصاصی رزونانس مغناطیسی برای اولین بار جهت تشخیص افتراقی سلول های سرطان پستان ( mcf-7 ) از طریق بررسی اندازه گیری میزان تغییر زمان آسایش اسپین ـ شبکه (طولی)، غلظت یون گادولینیوم و شدت سیگنال به کار گرفته شده است. مواد و روش ها: سلول های سرطانی پستان ( mcf-7 ) همر...
BACKGROUND Acute pancreatitis (AP) is an acute inflammatory condition of the pancreas. The symptoms, treatment, and prognosis of mild and severe AP are different, and severe AP is a potentially life-threatening disease with a high incidence of complications and high mortality rate. Thus, it is urgent to develop an effective approach to reliably discriminate between mild and severe AP. METHODS...
BACKGROUND Novel potential MR imaging contrast agents Gd-tetra-carboranylmethoxyphenyl-porphyrin (Gd-TCP), Gd-hematoporphyrin (Gd-H), Gd-DTPA-9.2.27 against melanoma, Gd-DTPA-WM53 against leukemia and Gd-DTPA-C595 against breast cancer cells were synthesized and applied to mice with different human cancer cells (melanoma MM-138, leukemia HL-60, breast MCF-7). The relaxivity, the biodistribution...
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 ...
