In vivo imaging of muscarinic cholinergic receptors in temporal lobe epilepsy with a new PET tracer: [76Br]4-bromodexetimide. (1/23)

Muscarinic acetyl cholinergic receptors (mAChRs) may be involved in the pathophysiology of partial epilepsy. Previous experimental and imaging studies have reported medial temporal abnormalities of mAChR in patients with medial temporal lobe epilepsy (MTLE). Suitable radiotracers for mAChR are required to evaluate these disturbances in vivo using PET. Dexetimide is a specific mAChR antagonist that has been labeled recently with 76Br. This first study in humans focused on regional distribution and binding kinetics of [76Br]4-bromodexetimide (BDEX) in patients with MTLE. METHODS: Ten patients with well-lateralized MTLE had combined MRI, 18F-fluorodeoxyglucose (FDG) PET and 76Br-BDEX PET studies. Time-activity curves were generated in PET-defined regions of interest, including the medial, polar and lateral regions of the temporal lobe; the basal ganglia; the external and medial occipital cortex; and the white matter. RESULTS: The highest radioactivity concentration was observed in the basal ganglia and in the cortical regions, whereas radioactivity was lower in the white matter. On late images of PET studies, 76Br-BDEX uptake was statistically significantly decreased only in the medial temporal region ipsilateral to the seizure focus (1.37 +/-0.28, P < 0.01) as determined by FDG PET imaging, anatomic MRI and electroencephalogram correlation, compared with the contralateral medial temporal region (1.46 +/- 0.31). CONCLUSION: 76Br-BDEX concentration is reduced in the temporal lobe ipsilateral to the seizure focus in patients with MTLE. This preliminary study suggests that 76Br-BDEX is a suitable radiotracer for studies of mAChR in humans. Further studies are required to investigate the potential value of 76Br-BDEX PET in other neurological disorders with muscarinic disturbances.  (+info)

Synthesis of [76Br]bromofluorodeoxyuridine and its validation with regard to uptake, DNA incorporation, and excretion modulation in rats. (2/23)

This investigation aimed to validate 5-[76Br]bromo-2'-fluoro-2'-deoxyuridine (BFU) as a proliferation marker using PET. METHODS: Five megabecquerels 76Br-BFU were injected into the tail vein of Sprague-Dawley rats. At 6 or 16 h after injection, the rats were killed and the radioactivity concentration was measured in 6 different organs and blood. The fraction of radioactivity incorporated into DNA was determined for the spleen and small intestine. In parallel experiments, the animals were pretreated with hydroxyurea. In a few experiments, the urinary excretion of radioactivity was measured from administration of 76Br-BFU until 6 h. A sample of urine was analyzed with HPLC. In separate experiments, rats were given different doses of cimetidine, and the organ uptake and the fraction of radioactivity in DNA were determined at 24 h. RESULTS: The highest organ uptake of radioactivity was found in the spleen, followed by the small intestine. Approximately 90% of the radioactivity in these organs was incorporated into DNA, and inhibition by hydroxyurea was pronounced. Intact tracer constituted more than 95% of the radioactivity in urine. With cimetidine, the uptake of radioactivity increased approximately 2-5 times at different doses, whereas the urine radioactivity decreased markedly. CONCLUSION: 76Br-BFU was predominantly incorporated into DNA after administration in vivo in rats. If cimetidine was given in combination with the tracer, an increased contrast of radioactivity concentration between organs of high proliferation and organs of low proliferation was observed. The investigation suggested that 76Br-BFU has good potential as a PET tracer for the assessment of proliferation in vivo.  (+info)

Rat studies comparing 11C-FMAU, 18F-FLT, and 76Br-BFU as proliferation markers. (3/23)

We analyzed and compared 1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-[methyl-(11)C]thymine ((11)C-FMAU), 3'-deoxy-3'-[(18)F]fluorothymidine ((18)F-FLT) and 1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-[(76)Br]bromouracil ((76)Br-BFU) with respect to tissue uptake, DNA incorporation, and excretion modulation in rats. The goal of the investigation was to evaluate the efficiency of the 3 nucleoside tracers as potential tracers for measuring proliferation. METHODS: Sprague-Dawley rats were divided into 3 groups and administered 5 MBq (11)C-FMAU, 1 MBq (18)F-FLT, or 2 MBq (76)Br-BFU. For each tracer, a subgroup was also administered 6 mg/kg cimetidine. The rats in the (11)C-FMAU group were killed at 5, 20, 40, 60, and 80 min after injection; the rats in the (18)F-FLT group were killed at 80 min and 2 and 4 h; and the rats in the (76)Br-BFU group were killed at 5, 20, 40, and 80 min and 2, 4, 6, and 24 h. Samples of blood, liver, kidney, spleen, and intestine were taken, and the radioactivity was measured. DNA separation was made in the samples of spleen, and the radioactivity in the DNA fraction was measured. RESULTS: Maximal uptake of radioactivity was seen in the spleen and intestine, organs with active DNA synthesis. The highest relative radioactivity uptake was at 60 min in the (11)C-FMAU groups and at 4 h in the (18)F-FLT group. In the (76)Br-BFU group, the uptake increased gradually during the observation period, and uptake of radioactivity increased markedly in rats receiving cimetidine. Cimetidine did not affect radioactivity uptake in the (11)C-FMAU or (18)F-FLT groups. The fraction of radioactivity in DNA was 78% in spleen at 60 min in the (11)C-FMAU group, 80% at 60 min and 97% at 4 h in the (76)Br-BFU group. The DNA-incorporation was only 2% in the (18)F-FLT group. CONCLUSION: (76)Br-BFU predominantly incorporates into DNA and has great potential as a PET tracer for the assessment of proliferation in vivo. (11)C-FMAU also may have potential as a proliferation marker, but the observation time is limited. (18)F-FLT does not incorporate into DNA and is therefore not a direct marker of proliferation.  (+info)

Measurement of the extracellular space in brain tumors using 76Br-bromide and PET. (4/23)

Brain edema significantly contributes to the clinical course of human brain tumor patients. There is evidence that an enlargement of the extracellular space (ECS) is involved in the development of brain edema. Although T2-weighted magnetic resonance (T2-MR) images represent brain edema by its increased water content, they do not differentiate ECS enlargement from increased intracellular water content. METHODS: On the basis of the known distribution of bromide in the ECS, we used (76)Br-bromide and PET to measure the regional ECS in 9 brain tumor patients. Transport rate constants and the distribution volume (DV) of (76)Br-bromide in normal brain and tumor were derived from dynamic PET scans and the measured (76)Br-bromide concentration in arterial plasma. We evaluated different models regarding their reliability in estimating the ECS. RESULTS: Assuming that the DV of (76)Br-bromide represents the ECS, robust estimates were possible for all investigated regions. In normal brain, ECS was within a narrow range-for example, occipital lobe, 19.9% +/- 3.1%-and was lower in 2 dexamethasone-treated patients compared with untreated patients. In 7 of 9 tumors, increased ECS ranged between 43.8% and 61.1%. ECS increases were confined to the tumor mass and did not extend into peritumoral edematous brain. Two patients with large hyperintense lesions according to T2-MR images showed normal ECS values within the lesion. CONCLUSION: (76)Br-Bromide PET allows a quantitative measurement of the ECS in brain edema and in normal brain. The discrepancies between lesions shown by T2-MRI and regional ECS enlargement as measured with PET challenge the concept of tumor-induced brain edema.  (+info)

Metabolism of bromide and its interference with the metabolism of iodine. (5/23)

The present knowledge about the metabolism of bromide with respect to its goitrogenic effects, including some conclusions drawn from our recent research on this subject, is reviewed. Firstly, the biological behavior of bromide ion is compared with that of chloride and iodide. Secondly, the details about distribution and kinetics of bromide ions in the body and in 15 different organs and tissues of the rat are given. Significant correlation between the values of the steady-state concentration of bromide in the respective tissue and of the corresponding biological half-life was found in most tissues examined. A remarkably high concentration of radiobromide was found in the skin, which represents, due to its large mass, the most abundant depot of bromide in the body of the rat. Thirdly, the effects of excessive bromide on the rat thyroid are summarized, along with the interference of exogenous bromide with the whole-body metabolism of iodine. It is suggested that high levels of bromide in the organism of experimental animals can influence their iodine metabolism in two parallel ways: by a decrease in iodide accumulation in the thyroid and skin (and in the mammary glands in lactating dams), and by a rise in iodide excretion by kidneys. By accelerating the renal excretion of iodide, excessive bromide can also influence the pool of exchangeable iodide in the thyroid. Finally, our recent results concerning the influence of high bromide intake in the lactating rat dam on iodine and bromide transfer to the suckling, and the impact of seriously decreased iodine content and increased bromide concentration in mother's milk on the young are discussed. We must state, however, that the virtue of the toxic effects of excessive bromide on the thyroid gland and its interference with the biosynthesis of thyroid hormones, as well as the exact mechanism of bromide interference with postnatal developmental processes remains to be elucidated.  (+info)

Biological half-life of bromide in the rat depends primarily on the magnitude of sodium intake. (6/23)

The parallel course of the excretion rates of bromide and sodium ions was demonstrated in adult male and female rats administered simultaneously with potassium 82Br-bromide and 24Na-sodium chloride. The animals were exposed to various intakes of sodium ions accompanied with five different anions: Br-, Cl-, HCO3-, ClO4-, and SCN-. Regardless of the anion accompanying the sodium ion, the excretion rates of 82Br- and 24Na+ ions were proportional to the magnitude of sodium intake in the animals. Hence, we have proved our hypothesis that the biological half-life of bromide depends on the magnitude of sodium intake rather than on the intake of chloride.  (+info)

Synthesis and in vivo evaluation of 2 high-affinity 76Br-labeled sigma2-receptor ligands. (7/23)

The sigma(2)-receptor has been shown to be upregulated in proliferating tumors cells. The purpose of this study was to compare 3'-deoxy-3'-(18)F-fluorothymidine ((18)F-FLT) and 2 new (76)Br-radiolabeled compounds that have a high affinity and selectivity for the sigma(2)-receptor. These are 5-bromo-N-(4-(3,4-dihydro-6,7-dimethoxyisoquinolin-2(1H)-yl)butyl)-2,3-dimethoxyb enzamide (compound (1)) and 5-bromo-N-(2-(3,4-dihydro-6,7-dimethoxyisoquinolin-2(1H)-yl)ethyl)-2-methoxybenza mide (compound (2)). METHODS: Two sigma(2)-receptor-binding ligands were prepared, from the corresponding tributylstannyl precursors using standard electrophilic chemistry, (76)Br-compound (1) ((76)Br-1) and (76)Br-compound (2) ((76)Br-2). (18)F-FLT, (76)Br-1, and (76)Br-2 were compared using allograft tumors of the EMT-6 cell line (mouse mammary adenocarcinoma) in biodistribution studies at 5 min, 0.5, 1, and 2 h. Imaging of (76)Br-1 and (18)F-FLT was also performed at 2 and 1 h, respectively. RESULTS: (76)Br-1 and (76)Br-2 were synthesized with yields between 50% and 70% with high specific activity. Both compounds showed uptake into the tumor with tumor-to-normal tissue ratios of (76)Br-1 being greater than both (76)Br-2 and (18)F-FLT. Except for the liver and kidney, all ratios were greater than 1 and uptake into the tumor was shown with microPET imaging for (76)Br-1. CONCLUSION: We were able to synthesize two (76)Br-radiolabeled compounds with a high yield and specific activity that target the sigma(2) receptor with high affinity and selectivity. The studies presented show that both of the flexible benzamide compounds can identify EMT-6 breast tumors in vivo. (76)Br-1 also has higher tumor-to-normal tissue ratios when compared with (76)Br-2 and (18)F-FLT. The high affinity and low nonspecific binding of (76)Br-1 indicates that it can be a potential PET radiotracer for imaging solid tumors.  (+info)

Noninvasive molecular imaging to detect transgene expression of lentiviral vector in nonhuman primates. (8/23)

Noninvasive imaging of a reporter gene is a new and promising technique to quantify transgene expression after gene therapy. This study was performed to demonstrate visualization of lentiviral-marked cells by PET. METHODS: We transduced nonhuman primate CD34+ hematopoietic cells with a lentiviral vector expressing a PET reporter gene, the mutant viral herpes simplex virus type 1-thymidine kinase (HSV1-sr39tk) gene. 1-(2-Fluoro-2-deoxy-beta-D-arabinofuranosyl)-76Br-5-bromouracil (76Br-FBAU) was used as the substrate for the viral tk enzyme. Upon phosphorylation, 76Br-FBAU was retained by cells and imaged by PET. The long half-life of 76Br, 16.2 h, permitted us to perform extended pharmacokinetic and imaging studies. RESULTS: 76Br-FBAU was retained in vascular tissues of the animals with transplanted tk lentiviral vector-transduced CD34+ cells. Elimination of 76Br-FBAU was through renal and hepatic excretion. CONCLUSION: Noninvasive molecular imaging using PET will help us, in the future, to define the contribution and distribution of cells and their progeny to tissue repair and development.  (+info)

The biological half-life of synthetic, radiochemically pure, biologically active [3H]1-deamino-8-D-arginine-vasopressin (dDAVP) in rats was found to be 5.33 +/- 0.28 (S.E.M.) min in the initial, transitional, fast phase and 56.28 +/- 3.27 min in the second, slow phase. The substance accumulated to the greatest extent in the kidney and small intestine and only slightly in the adenohypophysis. The results have suggested that the extended biological half-life may play a role in the more marked and longer antidiuretic effect of dDAVP. The explanation of the poor accumulation in the adenohypophysis may be that dDAVP does not possess an effect similar to that of corticotrophin releasing factor.

LPA levels are consistently elevated in the ascites of ovarian cancer patients (41 , 42) and likely contributing to the pathophysiology of ovarian cancer (6) . The mechanisms leading to the elevated levels of LPA in ovarian cancer ascites are not currently clear. Although ovarian cancer cells can release LPA into cell supernatants (11 , 12) , it is not known whether ovarian cancer cells or other cellular components in ascites are the primary source of LPA. Furthermore, it is not known whether the increased levels are because of increased rates of production or decreased rates of degradation. We have demonstrated that the major mechanism of LPA degradation by ovarian cancer cells is through an LPP-like activity (16) .. The LPP family includes at least three members, LPP-1, LPP-2, and LPP-3 isoforms (13 , 38 , 39) .

Our client, a 21-year-old farmer, was working on his 1969 Ford New Holland combine when an accident cost him his leg. He was using the machine to harvest and thresh wheat. In this type of combine, after the wheat is collected, the machine separates the heads from the straw and deposits the heads in a holding tank. The separation is facilitated by two rotating augers, a leveling auger and a discharge auger. They help to move the grain through the machine. At the time of the accident, the discharge auger was clogged, and our client was trying to reach a stick to fix it. As he leaned forward, however, his shirt was caught on the bolt of the leveling auger, and he was pulled down into the tank. His foot slipped beneath the discharge augers shield and was severely injured. He had to have his leg amputated below the knee. We argued that the combines protruding bolt was defective, the shields insufficient, and the manufacturers manual deficient in explaining how to safely fix discharge auger clogs. ...

I dont think polarization is the issue. Adding $\ce{FeBr3}$ is just to reduce the $\ce{Br-Br}$ bond strength, speeding up the reaction (attack of the aromatic ring on the bromine is part of the rate determining step, which is slow in the bromination of benzene). It functions as a catalyst being recycled when the $\ce{Br-}$ grabs a $\ce{H+}$ to restore aromaticity in the ring. Im pretty sure - at least I see no reason to doubt - that the catalyst requirements for the bromination of anisole and the bromination of phenol do not differ much, if at all. That is, no catalyst is required for the bromination of anisole.. ...

Other manufacturers also produce battery powered augers, notably Ion, which first marketed an electric model in 2012; Strike Master, owned by angling powerhouse Rapala; and fellow winter-fishing heavyweight Clam, which sells an auger kit that can be paired with a cordless drill.. The breakthrough that successfully brought K-Drills to market occurred about four years ago when Milwaukee brand power tools developed a {-inch drill that was brushless and powered by an 18-volt lithium-ion battery. The drills battery worked well in cold weather and delivered considerably more power to the auger ...

As an original result, we evidence a three-step mechanism to describe the resonant production of S+: the Auger recombination in the HS* fragment is followed for the A (3)Pi and c (1)Pi states by the S++H fragmentation mechanism.

This paper describes our recent work in which CTAB (cetyltrimethylammonium bromide) micelles are used as catalytic platforms for performing bromination and oxidation reactions in water. The bromide counter ion is used to prepare Br2 in situ which is subsequently employed as a brominating and oxidizing agent. In this process the bromide is rapidly oxidized to bromine using BPO (benzoic peroxyanhydride). The reaction is facilitated by the micelle which improves the BPO solubility and its proximity with Br-. Several example reactions are discussed including micelle-assisted bromination of cholesterol and methyl styrene along with an example of mild oxidation of benzyl alcohol to form benzaldehyde. These examples illustrate the use of bromine as a mild oxidizing agent and also as a brominating agent. Kinetic studies of Br2 formation and cholesterol bromination are also presented ...
