INTRODUCTION We describe five patients receiving a re-implantation (RI) after post-operative dosimetry of the primary 125-I permanent prostate brachytherapy (BT) for prostate cancer revealed an insufficient dose coverage. MATERIALS AND METHODS Five out of 222 consecutive patients treated (from March, 2001 to August, 2012) with 125-I BT, received a RI after dosimetric verification by CT and MR...
این آزمایش در سال زراعی 90- 1389 به صورت کرتهای خرد شده در قالب طرح بلوکهای کامل تصادفی با سه تکرار در ایستگاه تحقیقات کشاورزی بایعکلاء (نکاء) اجرا شد. عامل اصلی دور آبیاری شامل 1I، 2 I، 3I و 4 I(به ترتیب 75 ، 100 ، 125 و 150 میلیمتر تبخیر تجمعی از تشت تبخیر) و عامل فرعی نیتروژن معادل صفر،200 و 400 کیلوگرم اوره در هکتار بود. نتایج نشان داد بیشترین عملکرد علوفهتر در هکتار با مصرف 184 کیلوگ...
BACKGROUND The aim of this study was to determine if an intraoperative injection of iodine-125-labeled methylene blue ((125)I-MB) is a sensitive and effective method for detecting SLNs in women with breast cancer. STUDY DESIGN Sixty-two women were enrolled in an extended phase II trial using (125)I-MB to guide SLNB. All patients were anesthetized and then injected subcutaneously with 1 mCi (1...
N-acetylglucosaminyltransferase V (GnT-V) is one of the most relevant glycosyltransferases to tumor invasion and metastasis. Based on previous findings of molecular recognition between GnT-V and synthetic substrates, we designed and synthesized a p-iodophenyl-derivatized trisaccharide, 2-(4-iodophenyl)ethyl 6-O-[2-O-(2-acetamido-2-deoxy-β-D-glucopyranosyl)-α-d-mannopyranosyl]-β-D-glucopyranosid...
The dynamics of ABCA1-mediated apoA-I lipidation were investigated in intact human fibroblasts induced with 22(R)-hydroxycholesterol and 9-cis-retinoic acid (stimulated cells). Specific binding parameters of (125)I-apoA-I to ABCA1 at 37 degrees C were determined: K(d) = 0.65 microg/ml, B(max) = 0.10 ng/microg cell protein. Lipid-free apoA-I inhibited the binding of (125)I-apoA-I to ABCA1 more e...
To map the structure of a ligand-gated ion channel, we used the photolabile polyamine-containing toxin MR44 as photoaffinity label. MR44 binds with high affinity to the nicotinic acetylcholine receptor in its closed channel conformation. The binding stoichiometry was two molecules of MR44 per receptor monomer. Upon UV irradiation of the receptor-ligand complex, (125)I-MR44 was incorporated into...
The present study examined whether metabolism of the putative angiotensin-(1-7) receptor agonist and antagonist [angiotensin-(1-7) and D-alanine(7) angiotensin-(1-7), respectively] altered their ability to interact with angiotensin AT(1), AT(2), and AT(4) receptor subtypes. Both angiotensin-(1-7) and D-alanine(7) angiotensin-(1-7) competed with low affinity for (125)I-sarcosine(1), isoleucine(8...
The mechanism for consumption of terminal complement components and release of bound components from the surface of serum-resistant salmonella minnesota S218 was studied. Consumption of C8 and C9 by S218 occurred through interaction with C5b67 on the bacterial surface because C8 and C9 were consumed when added to S218 organisms previously incubated in C8-deficient serum and washed to remove all...
UNLABELLED Noninvasive determination of amyloid-β peptide (Aβ) deposition has important significance for early diagnosis and medical intervention for Alzheimer's disease (AD). In the present study, we investigated the availability of radiolabeled DRM106 ((123/125)I-DRM106 [6-iodo-2-[4-(1H-3-pyrazolyl)phenyl]imidazo[1,2-a]pyridine]), a compound with sufficient affinity for the synthesis of human...
Comparative studies were made of the metabolism of plasma high density lipoprotein (HDL) and low density lipoprotein (LDL) by cultured normal human fibroblasts. On a molar basis, the surface binding of (125)I-HDL was only slightly less than that of (125)I-LDL, whereas the rates of internalization and degradation of (125)I-HDL were very low relative to those of (125)I-LDL. The relationships of i...
