A single subcutaneous injection of 3.3'-methyliminobis-(N-methylpropylamine) caused edema and necrosis in the hypothalamus and medulla oblongata of rats, mice, and gerbils. Most other aliphatic triamines were ineffective. The lesions were very similar in character and distribution to those caused by
OBJECTIVE
To clarify the diagnostic ability of combining imaging methods to diagnose hepatocellular carcinoma (HCC) using Sonazoid®-enhanced ultrasound (US), gadolinium diethylene-triamine-pentaacetic acid-enhanced (Gd-EOB-DTPA) magnetic resonance imaging (MRI), and contrast-enhanced computed
BACKGROUND
The prognostic and predictive value of magnetic resonance (MR) investigations in clinical oncology may be improved by implementing strategies for discriminating between viable and necrotic tissue in tumors. The purpose of this preclinical study was to investigate whether the extent of
It has been demonstrated that the ventromedial hypothalamus (VMH) of alloxan-induced diabetic mice is protected from subsequent gold thioglucose (GTG)-induced lesions. Another compound, 3,3'-methyliminobis-(N-methylpropylamine) (MIMPA), a triamine structurally unrelated to GTG, has been shown to
Recently we showed that a number of carboxylated near-infrared fluorescent (NIRF) cyanine dyes possess strong necrosis avid properties in vitro as well as in different mouse models of spontaneous and therapy-induced tumor necrosis, indicating their potential use for cancer diagnostic- and prognostic
OBJECTIVE
Most effective antitumor therapies induce tumor cell death. Non-invasive, rapid and accurate quantitative imaging of cell death is essential for monitoring early response to antitumor therapies. To facilitate this, we previously developed a biocompatible necrosis-avid near-infrared
Patients with primary central nervous system lymphoma (PCNSL) are treated with high-dose methotrexate-based chemotherapy, which requires hospitalization and extensive expertise to manage related toxicity. The use of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) could
To evaluate the potential of gadolinium-diethylene triamine pentaacetic acid (DTPA)-enhanced magnetic resonance imaging (MRI) in the quantification of infarct size in patients with a first acute myocardial infarction, 24 patients with a first acute myocardial infarction were studied by
Bipiperidyl mustard and a neurotoxic triamine are known to cause edematous and/or necrotizing lesions in particular areas of hypothalamus and dorsal medulla but not in spinal cord. Experimental allergic encephalomyelitis (EAR) causes widespread inflammatory lesions that are especially numerous in
Viperbites undeniably cause local manifestations such as hemorrhage and myotoxicity involving substantial degradation of extracellular matrix (ECM) at the site of envenomation and lead to progressive tissue damage and necrosis. The principle toxin responsible is attributed to snake venom
BACKGROUND
Proximity to traffic-related pollution has been associated with poor respiratory health in adults and children.
OBJECTIVE
We wished to test the hypothesis that particulate matter (PM) from high-traffic sites would display an enhanced capacity to elicit inflammation.
METHODS
We examined
Male SAS/4 mice were injected i.v. with 6.6 kBq 239Pu-citrate. After 1 or 24 h a single i.p. injection of 15 or 30 mumol kg-1 or repeated (three or four) daily injections of 30 mumol kg-1 of tetra-THB-spermine were given, and at 4 or 7 days Pu retention was measured in liver, kidneys and femur.
Forty renal transplant recipients were subjected to 99m Technicium Diethylene triamine pentacetic acid (DTPA)scans at regular intervals & whenever there was suspection of rejection. Serial scans of a group of 15 recipients from immediate post transplant period till withdrawal of cyclosporine were
The purpose of this study was to test the hypothesis that decreasing liver perfusion in rabbits results in an increase in thermal lesion size and that these effects can be accurately monitored using magnetic resonance imaging (MRI). We additionally tested the hypothesis that the increase in thermal
Investigation on designed polyaminoanthraquinones revealed that the anthraquinones bearing triamine motifs are generally more potent than their counterparts with diamine or tetramine motifs. Compared with the reference drug mitoxantrone (MTX), 9b and 9c exhibited better inhibitory activity on
