Absorption, metabolism, and excretion of 14C-temozolomide following oral administration to patients with advanced cancer. (1/623)

The purpose of this study is to characterize the absorption, metabolism, and excretion of carbon 14-labeled temozolomide (14C-TMZ) administered p.o. to adult patients with advanced solid malignancies. On day 1 of cycle 1, six patients received a single oral 200-mg dose of 14C-TMZ (70.2 microCi). Whole blood, plasma, urine, and feces were collected from days 1-8 and on day 14 of cycle 1. Total radioactivity was measured in all samples. TMZ, 5-(3-methyltriazen-1-yl)imidazole-4-carboxamide (MTIC), and 4-amino-5-imidazole-carboxamide (AIC) concentrations were determined in plasma, and urine and plasma samples were profiled for metabolite/degradation products. Maximum TMZ plasma concentrations were achieved between 0.33 to 2 h (mean, 1.2 h), and half-life, apparent volume of distribution, and oral clearance values averaged 1.9 h, 17 liters/m2, and 104 ml/min/m2, respectively. A first-order absorption, one-compartment linear model, which included first-order formation of MTIC from TMZ and elimination of MTIC via degradation to AIC, and a peripheral distribution compartment for AIC, adequately described the plasma TMZ, MTIC, and AIC concentrations. MTIC systemic clearance was estimated to be 5384 ml/min/m2, and the half-life was calculated to be 2.5 min. Metabolite profiles of plasma at 1 and 4 h after treatment showed that 14C-derived radioactivity was primarily associated with TMZ, and a smaller amount was attributed to AIC. Profiles of urine samples from 0-24 h revealed that 14C-TMZ-derived urinary radioactivity was primarily associated with unchanged drug (5.6%), AIC (12%), or 3-methyl-2,3-dihydro-4-oxoimidazo[5,1-d]tetrazine-8-carboxyl ic acid (2.3%). The recovered radioactive dose (39%) was principally eliminated in the urine (38%), and a small amount (0.8%) was excreted in the feces. TMZ exhibits rapid oral absorption and high systemic availability. The primary elimination pathway for TMZ is by pH-dependent degradation to MTIC and further degradation to AIC. Incomplete recovery of radioactivity may be explained by the incorporation of AIC into nucleic acids.  (+info)

Apoptosis induced by growth factor withdrawal in fibroblasts overproducing fructose 2,6-bisphosphate. (2/623)

Fructose 2,6-bisphosphate is a potent endogenous stimulator of glycolysis. A high aerobic glycolytic rate often correlates with increased cell proliferation. To investigate this relationship, we have produced clonal cell lines of Rat-1 fibroblasts that stably express transgenes coding for 6-phosphofructo-2-kinase, which catalyzes the synthesis of fructose 2,6-bisphosphate, or for fructose 2,6-bisphosphatase, which catalyzes its degradation. While serum deprivation in culture reduced the growth rate of control cells, it caused apoptosis in cells overproducing fructose 2,6-bisphosphate. Apoptosis was inhibited by 5-amino-4-imidazolecarboxamide riboside, suggesting that 5'-AMP-activated protein kinase interferes with this phenomenon.  (+info)

Effect of AMPK activation on muscle glucose metabolism in conscious rats. (3/623)

The effect of AMP-activated protein kinase (AMPK) activation on skeletal muscle glucose metabolism was examined in awake rats by infusing them with 5-aminoimidazole-4-carboxamide 1-beta-D-ribofuranoside (AICAR; 40 mg/kg bolus and 7.5 mg. kg-1. min-1 constant infusion) along with a variable infusion of glucose (49.1 +/- 2.4 micromol. kg-1. min-1) to maintain euglycemia. Activation of AMPK by AICAR caused 2-deoxy-D-[1,2-3H]glucose (2-DG) uptake to increase more than twofold in the soleus and the lateral and medial gastrocnemius compared with saline infusion and occurred without phosphatidylinositol 3-kinase activation. Glucose uptake was also assessed in vitro by use of the epitrochlearis muscle incubated either with AICAR (0.5 mM) or insulin (20 mU/ml) or both in the presence or absence of wortmannin (1.0 microM). AICAR and insulin increased muscle 2-DG uptake rates by approximately 2- and 2.7-fold, respectively, compared with basal rates. Combining AICAR and insulin led to a fully additive effect on muscle glucose transport activity. Wortmannin inhibited insulin-stimulated glucose uptake. However, neither wortmannin nor 8-(p-sulfophenyl)-theophylline (10 microM), an adenosine receptor antagonist, inhibited the AICAR-induced activation of glucose uptake. Electrical stimulation led to an about threefold increase in glucose uptake over basal rates, whereas no additive effect was found when AICAR and contractions were combined. In conclusion, the activation of AMPK by AICAR increases skeletal muscle glucose transport activity both in vivo and in vitro. This cellular pathway may play an important role in exercise-induced increase in glucose transport activity.  (+info)

5' AMP-activated protein kinase activation causes GLUT4 translocation in skeletal muscle. (4/623)

It has previously been reported that exercise causes an increase in glucose uptake in skeletal muscle and also an increase in 5' AMP-activated protein kinase (AMPK) activity. 5-Aminoimidazole-4-carboxamide-1-beta-D-ribofuranoside (AICA-riboside), an analog of adenosine, is taken up into cells and phosphorylated to form AICA-riboside monophosphate (ZMP), which can also activate AMPK. This study was designed to determine whether the increase in glucose uptake observed with AMPK activation by AICA-riboside is due to GLUT4 translocation from an intracellular location to the plasma membranes, similar to that seen in response to contraction. Rat hindlimbs were perfused with Krebs-Henseleit bicarbonate containing 4% bovine serum albumin, washed bovine erythrocytes, 8 mmol/l glucose, and +/-2 mmol/AICA-riboside or +/-60 nmol/l insulin. Perfusion medium containing AICA-riboside was found to significantly increase AMPK activity, glucose uptake, and GLUT4 translocation in skeletal muscle above basal levels. Insulin-perfused muscles showed significant increases in glucose uptake and GLUT4 translocation, but AMPK activation was not significantly changed from basal levels. These results provide evidence that the increased glucose uptake observed with AMPK activation by AICA-riboside in perfused rat hindlimb muscles is due to an increase in the translocation of GLUT4 to surface membranes.  (+info)

Translocation of myocardial GLUT-4 and increased glucose uptake through activation of AMPK by AICAR. (5/623)

Insulin increases glucose uptake through the translocation of GLUT-4 via a pathway mediated by phosphatidylinositol 3-kinase (PI3K). In contrast, myocardial glucose uptake during ischemia and hypoxia is stimulated by the translocation of GLUT-4 to the surface of cardiac myocytes through a PI3K-independent pathway that has not been characterized. AMP-activated protein kinase (AMPK) activity is also increased by myocardial ischemia, and we examined whether AMPK stimulates glucose uptake and GLUT-4 translocation. In isolated rat ventricular papillary muscles, 5-aminoimidazole-4-carboxyamide-1-beta-D-ribofuranoside (AICAR), an activator of AMPK, as well as cyanide-induced chemical hypoxia and insulin, increased 2-[(3)H]deoxyglucose uptake two- to threefold. Wortmannin, a PI3K inhibitor, did not affect either the AICAR- or the cyanide-stimulated increase in deoxyglucose uptake but eliminated the insulin-stimulated increase in deoxyglucose uptake. Immunofluorescence studies demonstrated translocation of GLUT-4 to the myocyte sarcolemma in response to stimulation with AICAR, cyanide, or insulin. Preincubation of papillary muscles with the kinase inhibitor iodotubercidin or adenine 9-beta-D-arabinofuranoside (araA), a precursor of araATP (a competitive inhibitor of AMPK), decreased AICAR- and cyanide-stimulated glucose uptake but did not affect basal or insulin-stimulated glucose uptake. In vivo infusion of AICAR caused myocardial AMPK activation and GLUT-4 translocation in the rat. We conclude that AMPK activation increases cardiac muscle glucose uptake through translocation of GLUT-4 via a pathway that is independent of PI3K. These findings suggest that AMPK activation may be important in ischemia-induced translocation of GLUT-4 in the heart.  (+info)

Improvement by 5-amino-4-imidazole carboxamide riboside of the contractile dysfunction that follows brief periods of ischemia through increases in ecto-5-nucleotidase activity and adenosine release in canine hearts. (6/623)

5-Amino-4-imidazole carboxamide (AICA) riboside increases adenosine release in ischemic myocardium, suggesting that AICA riboside improves contractile dysfunction. In 49 open-chest dogs, contractile function assessed by fractional shortening (FS) was observed 3 h after the onset of reperfusion following 15 min of occlusion of the left anterior descending coronary artery. During reperfusion, the treatment with AICA riboside increased adenosine concentration in the coronary venous blood (536+/-44 vs. 281+/-21 pmol/ml at 3 min of reperfusion, p<0.001) and peak coronary hyperemic flow (367+/-13 vs. 300+/-21 ml/100 g per min, p<0.001) when compared with the untreated group. FS at 3h of reperfusion increased in the AICA riboside group (21.1+/-2.3 vs. 12.8+/-0.6% in the untreated group, p<0.001). AICA riboside increased myocardial ecto-5'-nucleotidase activity. Administration of adenosine also augmented coronary hyperemic flow and increased FS to the levels of the AICA riboside group. Either 8-phenyltheophylline (an antagonist of adenosine receptors) or alpha,beta-methylene-adenosine 5'-diphosphate (an inhibitor of ecto-5'-nucleotidase) completely abolished the increased coronary hyperemic flow and improvements of myocardial contractile function due to AICA riboside. Thus it was concluded that AICA riboside improves the contractile dysfunction that follows a brief period of ischemia via adenosine-dependent mechanisms.  (+info)

Effect of methotrexate on blood purine and pyrimidine levels in patients with rheumatoid arthritis. (7/623)

OBJECTIVE: The mechanism of anti-inflammatory effects of methotrexate (MTX) at low dose may relate to a decrease in availability of the purine precursor or it may depend on accumulation of 5-aminoimidazole-4-carboxamide (AICAR) and the anti-inflammatory nucleoside adenosine. The aim of this study was to evaluate the possible mechanism of action by analysis of changes in blood concentrations of purine and pyrimidine metabolites during MTX treatment. METHODS: Venous blood samples were collected from rheumatoid arthritis patients before and at different times for up to 7 days after the start of MTX treatment. Whole blood concentrations of adenosine, uridine, hypoxanthine, uric acid and erythrocyte nucleotides were measured by HPLC. RESULTS: The initial blood adenosine concentration was 0.073 +/- 0.013 microM and no differences were observed during MTX treatment. However, a decrease in uric acid concentration was observed from 205.5+/-13.5 to 160. 9+/-13.5 microM (P<0.05) within 24 h after MTX administration. The hypoxanthine concentration decreased in parallel with uric acid, while the uridine concentration decreased 48 h after MTX administration. No accumulation of AICAR-triphosphate (ZTP) was observed in the erythrocytes. CONCLUSIONS: MTX decreases circulating purine and pyrimidine concentrations, and their availability for DNA and RNA synthesis, which may affect immune cell proliferation and protein (cytokine) expression. The absence of adenosine concentration changes and lack of ZTP formation is evidence against an AICAR/adenosine mechanism, although localized adenosine concentration changes cannot be excluded.  (+info)

Chronic activation of 5'-AMP-activated protein kinase increases GLUT-4, hexokinase, and glycogen in muscle. (8/623)

This study was designed to determine whether chronic chemical activation of AMP-activated protein kinase (AMPK) would increase glucose transporter GLUT-4 and hexokinase in muscles similarly to periodic elevation of AMPK that accompanies endurance exercise training. The adenosine analog, 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR), has previously been shown to be taken up by cells and phosphorylated to form a compound (5-aminoimidazole-4-carboxamide ribonucleotide) that mimics the effect of AMP on AMPK. A single injection of AICAR resulted in a marked increase in AMPK in epitrochlearis and gastrocnemius/plantaris muscles 60 min later. When rats were injected with AICAR (1 mg/g body wt) for 5 days in succession and were killed 1 day after the last injection, GLUT-4 was increased by 100% in epitrochlearis muscle and by 60% in gastrocnemius muscle in response to AICAR. Hexokinase was also increased approximately 2. 5-fold in the gastrocnemius/plantaris. Gastrocnemius glycogen content was twofold higher in AICAR-treated rats than in controls. Chronic chemical activation of AMPK, therefore, results in increases in GLUT-4 protein, hexokinase activity, and glycogen, similarly to those induced by endurance training.  (+info)

The Dewoitine 37 was the first of a family of 1930s French-built monoplane fighter aircraft. The D.37 was a single-seat aircraft of conventional configuration. Its fixed landing gear used a tailskid. The open cockpit was located slightly aft of the parasol wing. The radial engine allowed for a comparatively wide fuselage and cockpit. Design of this machine was by SAF-Avions Dewoitine but owing to over work at that companies plant at the time, manufacture of the D.37/01 was transferred to Lioré et Olivier. They were high-wing monoplanes of all-metal construction with valve head blisters on their engine cowlings. The first prototype flew in October 1931. Flight testing resulted in the need for multiple revisions in both engine and airframe, so it was February 1934 before the second prototype flew. Its performance prompted the French government to order for 28 for the Armée de l'Air and Aéronavale. The Lithuanian government ordered 14 that remained in service with their Air Force until 1936, ...
The Noor-ul-Ain (Persian: نور العين, lit. 'the light of the eye') is one of the largest pink diamonds in the world, and the centre piece of the tiara of the same name. The diamond is believed to have been recovered from the mines of Golconda, Hyderabad in India. It was first in possession with the nizam Abul Hasan Qutb Shah, later it was given as a peace offering to the Mughal emperor Aurangazeb when he defeated him in a siege. It was brought into the Iranian Imperial collection after the Persian king Nader Shah Afshar looted Delhi in the 18th century.[citation needed] The Noor-ul-Ain is believed to have once formed part of an even larger gem called the Great Table diamond. That larger diamond is thought to have been cut in two, with one section becoming the Noor-ul-Ain and the other the Daria-i-Noor diamond. Both of these pieces are currently part of the Iranian Crown Jewels. The Noor-ul-Ain is the principal diamond mounted in a tiara of the same name made for Iranian Empress Farah ...
The Benoist Land Tractor Type XII was one of the first enclosed cockpit, tractor configuration aircraft built. Benoist used "Model XII" to several aircraft that shared the same basic engine and wing design, but differed in fuselage and control surfaces. The Type XII was a tractor-engined conversion of the model XII headless pusher aircraft that resembled the Curtiss pusher aircraft. Demonstration pilots used Benoist aircraft to demonstrate the first parachute jumps, and the tractor configuration was considered much more suitable for the task. The first example named the "Military Plane" had a small box frame covered fuselage that left the occupants mostly exposed to the wind. The later model XII "Cross Country Plane" had a full fuselage that occupants sat inside of. The first tractor biplane used a wooden fuselage with a small seat on top. The wings were covered with a Goodyear rubberized cloth. The first model XII was built in the spring of 1912. On 1 March 1912, Albert Berry used a headless ...

Maria Margaret La Primaudaye Pollen (10 April 1838 - c. 1919), known as Minnie, was a decorative arts collector. As Mrs John Hungerford Pollen, she became known during the early-twentieth century as an authority on the history of textiles, publishing Seven Centuries of Lace in 1908. Maria Margaret La Primaudaye was born into a Huguenot family on 10 April 1838, the third child of the Revd Charles John La Primaudaye, a descendant of Pierre de La Primaudaye. She was educated in Italy. Her family converted to Catholicism in 1851, and it was in Rome that her father met another recent English convert, John Hungerford Pollen, previously an Anglican priest and a decorative artist. She became engaged to Pollen, who was then seventeen years her senior, in the summer of 1854, and was married in the church of Woodchester monastery, near Stroud, Gloucester, on 18 September 1855. The Pollens initially settled in Dublin, where John Hungerford Pollen had been offered the professorship of fine arts at the ...

... is a painting by American illustrator Norman Rockwell that depicts a Boy Scout in full uniform standing in front of a waving American flag. It was originally created by Rockwell in 1942 for the 1944 Brown & Bigelow Boy Scout Calendar. The model, Bob Hamilton, won a contest to be in the painting and personally delivered a print to the Vice President of the United States at the time, Henry A. Wallace. The painting was created to encourage Scouts to participate in the war effort during World War II. The name of the painting, We, Too, Have a Job to Do, comes from a slogan that the Boy Scouts of America used in 1942 to rally scouts to support the troops by collecting metal and planting victory gardens. The model, Bob Hamilton, won a contest with his local council in Albany, New York, to be depicted in the painting. He traveled to Rockwell's studio in Arlington, Vermont, to model for Rockwell. Since Hamilton was a scout, the uniform shown in the painting was his, unlike some ...
