The bioavailability, dispostion kinetics and dosage of sulphadimethoxine in dogs. (1/6090)

The disposition kinetics of sulphadimethoxine were studied in six normal beagle dogs after intravenous injection of a single dose (55 mg/kg). The median (range) distribution and elimination half times of the drug were 2.36 (2.06-3.35) hours and 13.10 (9.71-16.50) hours, respectively. Total body clearance of the drug had a median value of 21.7 ml/kg/h and a mean value of 21.4 ml/kg/h. While the overall tissue to plasma level ratio (k12/k21) of the drug was 0.55 after distribution equilibrium had been attained, analogue computer simulated curves showed that at 24 hours the fractions (percentage) of the dose in the central and tissue compartments were 12 and 11%, respectively. The drug was shown, by equilibrium dialysis method, to be highly bound to plasma proteins (greater than 75%) within the usual therapeutic range (50 to 150 mug/ml) of plasma levels. The systemic availability of sulphadimethoxine from the oral suspension was 32.8% (22.5-80.0). Since the absorption half time, 1.87 (0.86-3.22) hours, was considerably shorter than the half-life, 13.10 (9.71-16.50) hours, of the drug, the rate of absorption would have little influence on the dosage regimen. Based on the experimental data obtained, a satisfactory dosage regimen might consist of a priming dose of 55 mg/kg by the intravenous route and maintenance doses of either 27.5 mg/kg of sulphadimethoxine injection given intravenously or 55 mg/kg of the oral suspension administered at 24 hour intervals. The adequacy and duration of therapy will depend upon the clinical response obtained.  (+info)

Cocaine metabolite kinetics in the newborn. (2/6090)

The study goal was to determine the half-life elimination of cocaine and benzoylecgonine (BZE) in the newborn. Three 0.3-mL blood samples were collected during the first day of life. Urine was collected once daily. Cocaine and BZE concentrations were determined by gas chromatography-mass spectrometry. An extraction method was developed for measuring low concentrations of cocaine and BZE in small (0.1 mL) blood samples. Cocaine had a half-life of 11.6 h in one subject. The half-life of BZE during the first day of life, based on blood data in 13 subjects, was 16 h (95% confidence interval [CI], 12.8 to 21.4 h). The half-life of BZE during the first week of life, based on urine data in 16 subjects, was 11.2 h (95% CI, 10.1 to 11.8 h). The novel extraction method for small blood sample volumes should be applicable to other basic drugs.  (+info)

Re-entering the translocon from the lumenal side of the endoplasmic reticulum. Studies on mutated carboxypeptidase yscY species. (3/6090)

Misfolded or unassembled secretory proteins are retained in the endoplasmic reticulum (ER) and subsequently degraded by the cytosolic ubiquitin-proteasome system. This requires their retrograde transport from the ER lumen into the cytosol, which is mediated by the Sec61 translocon. It had remained a mystery whether ER-localised soluble proteins are at all capable of re-entering the Sec61 channel de novo or whether a permanent contact of the imported protein with the translocon is a prerequisite for retrograde transport. In this study we analysed two new variants of the mutated yeast carboxypeptidase yscY, CPY*: a carboxy-terminal fusion protein of CPY* and pig liver esterase and a CPY* species carrying an additional glycosylation site at its carboxy-terminus. With these constructs it can be demonstrated that the newly synthesised CPY* chain is not retained in the translocation channel but reaches its ER lumenal side completely. Our data indicate that the Sec61 channel provides the essential pore for protein transport through the ER membrane in either direction; persistent contact with the translocon after import seems not to be required for retrograde transport.  (+info)

Cardiomegaly in the juvenile visceral steatosis (JVS) mouse is reduced with acute elevation of heart short-chain acyl-carnitine level after L-carnitine injection. (4/6090)

The long-term administration of L-carnitine was very effective in preventing cardiomegaly in juvenile visceral steatosis (JVS) mice, which was confirmed by heart weight as well as the lipid contents in heart tissue. After i.p. injection of L-carnitine, the concentration of free carnitine in heart remained constant, although serum free carnitine level increased up to 80-fold. On the other hand, a significant increase in short-chain acyl-carnitine level in heart was observed. These results suggest that increased levels of short-chain acyl-carnitine, not free carnitine, might be a key compound in the protective effect of L-carnitine administration in JVS mice.  (+info)

Protection against lymphocytic choriomeningitis virus infection induced by a reduced peptide bond analogue of the H-2Db-restricted CD8(+) T cell epitope GP33. (5/6090)

Recent investigations have suggested that pseudopeptides containing modified peptide bonds might advantageously replace natural peptides in therapeutic strategies. We have generated eight reduced peptide bond Psi(CH2-NH) analogues corresponding to the H-2Db-restricted CD8(+) T cell epitope (called GP33) of the glycoprotein of the lymphocytic choriomeningitis virus. One of these pseudopeptides, containing a reduced peptide bond between residues 6 and 7 (Psi(6-7)), displayed very similar properties of binding to major histocompatibility complex (MHC) and recognition by T cell receptor transgenic T cells specific for GP33 when compared with the parent peptide. We assessed in vitro and in vivo the proteolytic resistance of GP33 and Psi(6-7) and analyzed its contribution to the priming properties of these peptides. The Psi(6-7) analogue exhibited a dramatically increased proteolytic resistance when compared with GP33, and we show for the first time that MHC-peptide complexes formed in vivo with a pseudopeptide display a sustained half-life compared with the complexes formed with the natural peptide. Furthermore, in contrast to immunizations with GP33, three injections of Psi(6-7) in saline induced significant antiviral protection in mice. The enhanced ability of Psi(6-7) to induce antiviral protection may result from the higher stability of the analogue and/or of the MHC-analogue complexes.  (+info)

In vivo modulation of alternative pathways of P-450-catalyzed cyclophosphamide metabolism: impact on pharmacokinetics and antitumor activity. (6/6090)

The widely used anticancer prodrug cyclophosphamide (CPA) is activated in liver by a 4-hydroxylation reaction primarily catalyzed by cytochrome P-4502B and P-4502C enzymes. An alternative metabolic pathway involves CPA N-dechloroethylation to yield chloroacetaldehyde (CA), a P-4503A-catalyzed deactivation/neurotoxication reaction. The in vivo modulation of these alternative, competing pathways of P-450 metabolism was investigated in pharmacokinetic studies carried out in the rat model. Peak plasma concentrations (Cmax) for 4-OH-CPA and CA were increased by 3- to 4-fold, and apparent plasma half-lives of both metabolites were correspondingly shortened in rats pretreated with phenobarbital (PB), an inducer of P-4502B and P-4503A enzymes. However, PB had no net impact on the extent of drug activation or its partitioning between these alternative metabolic pathways, as judged from AUC values (area-under-the-plasma concentration x time curve) for 4-OH-CPA and CA. The P-4503A inhibitor troleandomycin (TAO) decreased plasma Cmax and AUC of CA (80-85% decrease) without changing the Cmax or AUC of 4-OH-CPA in uninduced rats. In PB-induced rats, TAO decreased AUCCA by 73%, whereas it increased AUC4-OH-CPA by 93%. TAO thus selectively suppresses CPA N-dechloroethylation, thereby increasing the availability of drug for P-450 activation via 4-hydroxylation. By contrast, dexamethasone, a P-4503A inducer and antiemetic widely used in patients with cancer, stimulated large, undesirable increases in the Cmax and AUC of CA (8- and 4-fold, respectively) while reducing the AUC of the 4-hydroxylation pathway by approximately 60%. Tumor excision/in vitro colony formation and tumor growth delay assays using an in vivo 9L gliosarcoma solid tumor model revealed that TAO suppression of CPA N-dechloroethylation could be achieved without compromising the antitumor effect of CPA. The combination of PB with TAO did not, however, enhance the antitumor activity of CPA, despite the approximately 2-fold increase in AUC4-OH-CPA, suggesting that other PB-inducible activities, such as aldehyde dehydrogenase, may counter this increase through enhanced deactivation of the 4-hydroxy metabolite. Together, these studies demonstrate that the P-4503A inhibitor TAO can be used to effectively modulate CPA metabolism and pharmacokinetics in vivo in a manner that decreases the formation of toxic metabolites that do not contribute to antitumor activity.  (+info)

Prediction of the effects of inoculum size on the antimicrobial action of trovafloxacin and ciprofloxacin against Staphylococcus aureus and Escherichia coli in an in vitro dynamic model. (7/6090)

The effect of inoculum size (N0) on antimicrobial action has not been extensively studied in in vitro dynamic models. To investigate this effect and its predictability, killing and regrowth kinetics of Staphylococcus aureus and Escherichia coli exposed to monoexponentially decreasing concentrations of trovafloxacin (as a single dose) and ciprofloxacin (two doses at a 12-h interval) were compared at N0 = 10(6) and 10(9) CFU/ml (S. aureus) and at N0 = 10(6), 10(7), and 10(9) CFU/ml (E. coli). A series of pharmacokinetic profiles of trovafloxacin and ciprofloxacin with respective half-lives of 9.2 and 4 h were simulated at different ratios of area under the concentration-time curve (AUC) to MIC (in [micrograms x hours/milliliter]/[micrograms/milliliter]): 58 to 466 with trovafloxacin and 116 to 932 with ciprofloxacin for S. aureus and 58 to 233 and 116 to 466 for E. coli, respectively. Although the effect of N0 was more pronounced for E. coli than for S. aureus, only a minor increase in minimum numbers of surviving bacteria and an almost negligible delay in their regrowth were associated with an increase of the N0 for both organisms. The N0-induced reductions of the intensity of the antimicrobial effect (IE, area between control growth and the killing-regrowth curves) were also relatively small. However, the N0 effect could not be eliminated either by simple shifting of the time-kill curves obtained at higher N0s by the difference between the higher and lowest N0 or by operating with IEs determined within the N0-adopted upper limits of bacterial numbers (IE's). By using multivariate correlation and regression analyses, linear relationships between IE and log AUC/MIC and log N0 related to the respective mean values [(log AUC/MIC)average and (log N0)average] were established for both trovafloxacin and ciprofloxacin against each of the strains (r2 = 0.97 to 0.99). The antimicrobial effect may be accurately predicted at a given AUC/MIC of trovafloxacin or ciprofloxacin and at a given N0 based on the relationship IE = a + b [(log AUC/MIC)/(log AUC/MIC)average] - c [(log N0)/(log N0)average]. Moreover, the relative impacts of AUC/MIC and N0 on IE may be evaluated. Since the c/b ratios for trovafloxacin and ciprofloxacin against E. coli were much lower (0.3 to 0.4) than that for ampicillin-sulbactam as examined previously (1.9), the inoculum effect with the quinolones may be much less pronounced than with the beta-lactams. The described approach to the analysis of the inoculum effect in in vitro dynamic models might be useful in studies with other antibiotic classes.  (+info)

Pharmacokinetics and urinary excretion of amikacin in low-clearance unilamellar liposomes after a single or repeated intravenous administration in the rhesus monkey. (8/6090)

Liposomal aminoglycosides have been shown to have activity against intracellular infections, such as those caused by Mycobacterium avium. Amikacin in small, low-clearance liposomes (MiKasome) also has curative and prophylactic efficacies against Pseudomonas aeruginosa and Klebsiella pneumoniae. To develop appropriate dosing regimens for low-clearance liposomal amikacin, we studied the pharmacokinetics of liposomal amikacin in plasma, the level of exposure of plasma to free amikacin, and urinary excretion of amikacin after the administration of single-dose (20 mg/kg of body weight) and repeated-dose (20 mg/kg eight times at 48-h intervals) regimens in rhesus monkeys. The clearance of liposomal amikacin (single-dose regimen, 0.023 +/- 0.003 ml min-1 kg-1; repeated-dose regimen, 0.014 +/- 0.001 ml min-1 kg-1) was over 100-fold lower than the creatinine clearance (an estimate of conventional amikacin clearance). Half-lives in plasma were longer than those reported for other amikacin formulations and declined during the elimination phase following administration of the last dose (from 81.7 +/- 27 to 30.5 +/- 5 h). Peak and trough (48 h) levels after repeated dosing reached 728 +/- 72 and 418 +/- 60 micrograms/ml, respectively. The levels in plasma remained > 180 micrograms/ml for 6 days after the administration of the last dose. The free amikacin concentration in plasma never exceeded 17.4 +/- 1 micrograms/ml and fell rapidly (half-life, 1.47 to 1.85 h) after the administration of each dose of liposomal amikacin. This and the low volume of distribution (45 ml/kg) indicate that the amikacin in plasma largely remained sequestered in long-circulating liposomes. Less than half the amikacin was recovered in the urine, suggesting that the level of renal exposure to filtered free amikacin was reduced, possibly as a result of intracellular uptake or the metabolism of liposomal amikacin. Thus, low-clearance liposomal amikacin could be administered at prolonged (2- to 7-day) intervals to achieve high levels of exposure to liposomal amikacin with minimal exposure to free amikacin.  (+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.
Results: After IV administration, the mean t½ of CK-3773274 was 4.52, 2.99, 33.8 and 8.14 hours in mouse, rat, dog and monkey, respectively. Mean total clearance (CL) was 8.81, 2.09, 3.30, and 11.2 mL/min/kg in the mouse, rat, dog, and monkey, respectively. Mean steady-state volume of distribution (Vss) was 3.14, 0.525, 10.5, and 7.76 L/kg in mouse, rat, dog, and monkey, respectively, which is near or above the average total body water in these species suggesting distribution into tissues. CK-3773274 was rapidly absorbed after oral administration, with median tmax values ranging from 0.25 (mouse) to 1.17 hours (monkey). Mean elimination half-life values (t½) after oral dosing were 3.41, 2.57 to 3.54, 28.7 and 12.1 hours in the mouse, rat, dog and monkey, respectively.

Following intravenous infusion, verapamil is eliminated bi-exponentially, with a rapid early distribution phase (half-life about four minutes) and a slower terminal elimination phase (half-life two to five hours). Following oral administration, the elimination half-life is three to seven hours. Approximately 50% of an administered dose is eliminated renally within 24 hours, 70% within five days. Up to 16% of a dose is excreted in the feces. About 3% to 4% of renally excreted drug is excreted as unchanged drug. The total clearance of verapamil is nearly as high as the hepatic blood flow, approximately 1 L/h/kg (range: 0.7-1.3 L/h/kg ...
The interest in developing peptide and protein drugs has been shadowed by their short elimination half-life and impermeability through biological membranes. Pegylation is widely attempted to extend their half-lives. However, pegylation results in heterogeneous species, leading to inconsistent drug efficacy, immunogenecity and side effects. An at least-equally-efficient delivery system that produces homogenous species is highly desired to substitute pegylation. Reversible lipidization takes a unique approach by conjugating fatty acids specifically to cysteines of peptide and protein through reducible disulfide linkage. This approach produces a single form of site-specific and controlled-release conjugate.; Using this approach, we successfully lipidized octreotide (OCT) and Tyr3-octreotide (TOC). Lipidization augmented the pharmacological effect of OCT on inhibiting growth hormone release in growth hormone releasing factor (GRF)-stimulated rats. Further pharmacokinetic studies demonstrated that ...
The kinetics of distribution of di-propranolol (P) to various organs and tissues were studied in the rat after an i.v. dose of 2 mg/kg. The disposition of the drug can be adequately described by a two-compartment open model with a distribution half-life of 4.8 min, a terminal blood half-life of 63 min and an apparent volume of distribution beta of 8.5 liters/kg. Higher tissue concentrations were found to be present in heart, brain and kidney. Although the disappearance rate of P from abdominal aorta, muscles, adipose tissue and whole brain paralleled that of blood, the elimination rate constant for atria and kidney was significantly reduced suggesting a specific binding of P. After an i.v. dose of 5 mg/kg, P distributed rapidly to various brain areas following a vascularity pattern with higher concentrations in cortical areas of earlier times. An equilibrium between various brain areas was observed at 2 to 3 hr after dosing. There was a parallel decay of P concentrations in the blood and in ...

Total body clearances (CL) of 1.8 +/- 0.2 ml/min/kg in monkeys and 7.7 +/- 1.1 ml/min/kg in dogs are low, indicating that, after an ig dose, little Wy-41,770 would be eliminated on first passage through the liver. The steady state volumes of distribution of 0.37 +/- 0.1 and 0.14 +/- 0.01 liters/kg, respectively, in monkeys and dogs are low, indicating limited extravascular distribution of Wy-41,770. Plasma half-lives of Wy-41,770 in rats and mice were, respectively, 10.8 and 8.4 hr. The longer ...
The mean serum concentrations of ciprofloxacin associated with a statistically significant improvement in survival in the rhesus monkey model of inhalational anthrax are reached or exceeded in adult and paediatric patients receiving oral and intravenous regimens (see Section 4.2 Dose and Method of Administration). Ciprofloxacin pharmacokinetics have been evaluated in various human populations. The mean peak serum concentration achieved at steady state in human adults receiving 500 mg orally every 12 hours is 2.97 microgram/mL, and 4.56 microgram/mL following 400 mg intravenously every 12 hours. The mean trough serum concentration at steady state for both of these regimens is 0.2 microgram/mL. In a study of 10 paediatric patients between 6 and 16 years of age, the mean peak plasma concentration achieved is 8.3 microgram/mL and trough concentrations range from 0.09 to 0.26 microgram/mL, following two 30-minute intravenous infusions of 10 mg/kg administered 12 hours apart. After the second ...
The mechanism of action of azithromycin is by inhibiting protein synthesis by bacteria, due to its 50S ribosomal binding lasubunidad avoiding peptide translocation.. After oral administration in humans, azithromycin is widely distributed throughout the body. Its bioavailability is about 37%. Administering azithromycin capsules after a large meal subiodisponibilidad decreases by at least 50%. The time required to reach peak plasma levels is two to three hours. Terminal half-life of plasma elimination half-life closely reflects tissue depletion two to four days.. In elderly volunteers (aged 65 years), after a five-day regimen were observed values ​​of area under the curve (AUC) slightly higher than those observed in younger volunteers (under 40 years) but these do not were considered clinically significant, and therefore is not recommended dosage adjustment.. In patients with moderate renal impairment (creatinine clearance less than 40 ml / min), no evidence of significant changes in ...
Esmolol is rapidly metabolized by hydrolysis of the ester linkage, chiefly by the esterases in the cytosol of red blood cells and not by plasma cholinesterases or red cell membrane acetylcholinesterase. Total body clearance in man was found to be about 20 L/kg/hr, which is greater than cardiac output; thus the metabolism of esmolol is not limited by the rate of blood flow to metabolizing tissues such as the liver or affected by hepatic or renal blood flow. Esmolol has a rapid distribution half-life of about 2 minutes and an elimination half-life of about 9 minutes.. Using an appropriate loading dose, steady-state blood levels of esmolol hydrochloride for dosages from 50 to 300 mcg/kg/min are obtained within five minutes. Steady-state is reached in about 30 minutes without the loading dose. Steady-state blood levels of esmolol increase linearly over this dosage range and elimination kinetics are dose-independent over this range. Steady-state blood levels are maintained during infusion but ...

Belatacept is an intravenously infused selective T cell costimulation blocker approved for preventing organ rejection in renal transplant recipients aged ≥18 years. This phase I trial examined the pharmacokinetics and pharmacodynamics (percentage CD86 receptor occupancy [%CD86RO]) of a single dose of belatacept (7.5 mg/kg) administered to kidney transplant recipients aged 12-17 years receiving a stable calcineurin inhibitor-based immunosuppressive regimen. Nine adolescents (mean age 15.1 years) who were seropositive for Epstein-Barr virus were enrolled; all completed the 6-month study. Pharmacokinetics suggested relatively low variability of exposure (coefficients of variation for maximum observed serum concentration [C max ] and area under the serum concentration-time curve from time zero extrapolated to infinity [AUC 0-INF ] were 20% and 25%, respectively). Mean half-life (T 1/2 ) occurred 7.2 days postinfusion. Belatacept total body clearance was 0.48 mL/h/kg, and volume of distribution at ...
In a randomized, double-blind, placebo-controlled, multiple-dose pharmacokinetic study, the safety and effect on intestinal flora of sparfloxacin (SPX) were determined in 12 healthy male volunteers (8 received SPX and 4 received a placebo). Following fasting and oral administration of 400 mg on day 1 and 200 mg on days 2 to 8, concentrations of the free drug in serum, urine, and feces were measured by high-performance liquid chromatography; serum and urine were also evaluated by a microbiological assay. All results, except those for renal excretion, exclude the glucuroconjugate metabolite. A mean peak concentration in serum (400-mg dose) of 0.56 +/- 0.13 mg/liter was measured 3.52 +/- 0.98 h after administration. Pharmacokinetic parameters (measured by high-performance liquid chromatography) were based on an open, one-compartment model and resulted in the following day 1 (calculated for the 200-mg dose), day 4 (recalculated for a single dose), and day 8 values (mean +/- standard deviation): area ...
Pharmacokinetic studies of PA 824 in healthy individuals in single as well as multiple dose studies have shown the drug is easily absorbed, orally bioavailable, safe and well tolerated, without significant adverse effects. In addition to the amount of PA 824, its maximal plasma concentration was reached in 4 to 5 h. The average elimination half life was 16 to 20 h with steady state reached in 5 to 6 times for multiple dosing. PA 824 was well tolerated at 1000 mg once a day for 5 days and 600 mg once a day for a week. The parameters were in line with once per day regimen. The adverse effects on management of PA 824 to healthy volunteers were trivial and the sole Enzalutamide supplier one of note was the dose-dependent reversible elevation of serum creatinine level. Pharmacodynamic reports of renal function indicated the increase in the serum creatinine levels can ergo perhaps not be ascribed to pathological effects of the drug on renal functions, but may be caused by the inhibition of tubular ...
The pharmacokinetics and oral bioavailability of 1,3-di(4-imidazolino-2-methoxyphenoxy) propane.lactate (DMP) was determined in male dogs following iv and po administrations of DMP.lactate containing trace amounts of [14C]DMP.HCl. Following the iv administration of [14C]DMP.lactate (2.5 mg/kg), plasma concentrations of DMP declined in a biexponential manner and were measurable to 48 hr. The terminal elimination half-life was 37.7 hr. The mean AUC0-infinity of DMP was 1.58 micrograms.hr/ml. The volume of distribution was 89 liters/kg and the body clearance was 27 ml/min/kg. The disposition of total radioactivity was similar to that of DMP. Approximately 14% of the dose was eliminated in urine as DMP or total radioactivity. Renal clearance was 10% of the body clearance. Following the po administration of [14C]DMP.lactate (14 mg/kg) the mean Cmax of total radioactivity and DMP was 0.20 and 0.17 micrograms/ml, respectively. The respective mean AUC0-T was 0.37 and 0.21 micrograms.hr/ml. The mean oral ...

There's been a lot of Half-Life 2 talk lately, what with Marc Laidlaw creatively writing some gender-swapped fan fiction that revealed his vision for the missing Episode 3 and Lever Softworks speeding up the release schedule of its Half-Life 2: Aftermath mod. In fact, it feels like there there's pretty much always a bit of Half-Life 2 chatter drifting around because it's a celebrated hunk of first-person shootery and we're still wondering (well, maybe not so much now) if we'll ever see Half-Life 3.It wasn't this most recent surge of Half-Life 2 nostalgia that led me to play through the final chapter of Half-Life 2 a total of 15 times in 2 days. I love Half-Life 2, and I'll still play certain chapters of it every now and then. But when I play it, I never play the last chapter, and I didn't want to this week, and I certainly didn't want to play it 15 times in two days. Also: I'll never play it again.Why I played it this week: I was working on

The ADME characteristics were investigated by the oral and IV routes in the rat. The bioavailability after the oral low and high doses were , 100% and approximately 50%, respectively. However, the bioavailability for the high dose was calculated using a lower IV dose. In addition, less than 1% of the parent compound was found in the faeces after the oral high dose, indicating practically complete absorption from the gastrointestinal tract. Therefore, 100% absorption by the oral route is assumed and is taken forward to risk characterisation. No sex difference was observed in blood kinetics at the low dose, however, in the high dose group, Cmax and AUC were higher in females than males. The elimination half life was 99-113 hours, irrespective of the dose, route or sex. The retention of radioactivity was low, with the majority (60%) of the radioactivity excreted by biliary route within 3 days of dosing. Approximately 20% was excreted in urine and a small amount of radioactivity exhaled as14CO2. ...
We'll probably never get another Half-Life game, but where official Valve canon fails us, series writer Marc Laidlaw does not. The former Valve employee who wrote Half-Life, Half-Life 2, and both of Half-Life 2's episodes has shared a fictional letter on his personal site that, once you swap around some proper nouns, sure reads like a plot summary of where the series would have gone after the events of Half-Life 2: Episode 2. To all intents and purposes, its the closest we have for an official synopsis for Half-Life 3.

Synthesis of a specific secretory protein was followed in the presence of actinomycin D and cordycepin (3-deoxyadenosine). The apparent half-life of the messenger RNA for this protein is significantly longer in the presence of actinomycin D than in the presence of cordycepin. These results suggest that actinomycin D studies of half-life in specialized cells may be inaccurate. ...

Results: Sixteen patients (median age 46 years, range 26-73) with non-small-cell lung cancer (NSCLC; n=5), colorectal cancer (CRC; n=4) or other tumor type (n=7) were enrolled and received treatment with cediranib at doses of 10 (n=3), 20 (n=3), 30 (n=3) or 45 (n=7) mg/day. The most common adverse events (AE) observed were diarrhea, fatigue, hypertension, hand-foot syndrome and proteinuria. No dose-limiting toxicities (DLTs) were observed at doses ≤30 mg/day. At 45 mg/day, 3/6 evaluable patients experienced a total of four DLTs (proteinuria, n=2; diarrhea, n=1; thrombocytopenia, n=1); therefore 30 mg/day was defined as the maximum tolerated dose (MTD). Following a single dose of cediranib 10-45 mg/day, the maximum plasma concentration was achieved between 2 and 4 hours post dosing and the overall mean terminal phase half-life was 21 hours. Following multiple dosing there were no time-dependent changes in PK parameters. At the MTD, the unbound minimum plasma concentration was ,5 times above the ...

OBJECTIVE: To compare pharmacokinetics of eltenac after first and last IV administrations (0.5 mg/kg), using a multiple dosing schedule. ANIMALS: 6 adult mares. PROCEDURE: Eltenac (50 mg/ml) was administered IV at a dosage of 0.5 mg/kg of body weight every 24 hours for days 0 through 4. On days 0 and 4, blood samples were collected before, then periodically for 8 hours after eltanac administration. Concentration of eltenac in plasma samples was determined by use of high-performance liquid chromatography. RESULTS: On day 0, median area under the plasma eltenac concentration versus time curve (AUC) was 6.77 microg.h/ml (range, 5.61 to 8.08 microg.h/ml), median plasma clearance was 1.23 ml/min/kg (range, 1.03 to 1.40 ml/min/kg), and median steady-state volume of distribution was 191 ml/kg (range, 178 to 218 ml/kg). Median terminal half-life of eltenac was 2.36 hours (range, 2.30 to 2.98 hours). On day 4, median eltenac AUC was 6.70 microg.h/ml (range, 5.21 to 7.44 microg.h/ml), median plasma ...

Calculation of local dehydration propensities. We introduce a descriptor of hydration tightness for soluble proteins defined as the mean residence time of hydrating molecules within a domain around each residue on the protein surface. The local mean residence time (,τ,i) of hydrating molecules at residue i is defined with respect to a spherical domain D(i) of 6.2-Å radius (approximately the width of three water layers; ref. 10) centered at the α-carbon of residue i. The actual computation of residence times is given in the Supplementary Material. The mean residence times were obtained from classic trajectories generated by molecular dynamic simulations (Supplementary Material).. Backbone exposure for protein targets. The extent of backbone exposure at a particular residue was determined by counting the number of nonpolar side chain groups contained within a 6.2-Å radius sphere (approximately the thickness of three water layers) centered at the α-carbon. The extent of backbone shielding (η) ...
This chapter has a preoccupation with the processes of physics, chemistry and biology. These processes are examined in a way that allows them to be seen as organic algorithms not unlike algorithms used in computer programming. To be honest, I am not totally clear what I see in this relationship, but it is very fertile for growing plot lines.. The second aspect of the chapter deals with time, entanglement and gravity. These are very loosely formed within my mind. Truth be told, I dont think anything lasts in my mind. Everything has a very short half-life within the chaos of my brain.

Protein engineering provides powerful tools to create useful proteins with desired properties. In this thesis, rational design principles have been used for development of fusion proteins that can interact with the neonatal Fc receptor (FcRn) for potential medical applications. FcRn is widely expressed in the human body. The natural ligands of FcRn are immunoglobulin G (IgG) and serum albumin (SA). FcRn can bind to both proteins in a pH dependent manner and endow them with an unusually long half-life in vivo. Protein building blocks interacting directly or indirectly with FcRn may potentially be used to either piggy-back on the FcRn-system for extension of the in vivo half-life or to saturate the system to decrease the in vivo half-life of the natural ligands. In this thesis, I have explored an FcRn binding affibody molecule (ZFcRn) and/or an albumin binding domain (ABD) for these purposes. In study I and II, the prolactin receptor was found to often be expressed in glioblastoma multiforme ...
Data available for the structurally and functionally similar read across chemicals has been reviewed to determine the half-life of the test chemical Tributylmethylammonium chloride (CAS no. 56375 -79 -2). The studies are as mentioned below: The half-life of the test chemical was determined at different pH range. The study was performed at pH of 4, 7 and 9, & at a temperature of 20°C, respectively. The half-life period of test chemical was determined to be ≥ 1 yr at pH 4, 7 and 9, respectively & at a temperature of 20°C and thus test chemical was reported to be hydrolytically stable. On the basis of this, test chemical is considered to be not hydrolysable. In an another study, the half-life of the test chemical was determined.The half-life value of test chemical was determined to be ranges from 5 to 63 days, respectively. Thus, based on the value, test chemical is considered to undergoe slow to negligible hydrolysis in water. For the test chemical, the hydrolysis half-life value was ...
The clinical pharmacokinetics of etoposide were studied in eight pediatric patients with refractory solid tumors. The α-phase half-life, β-phase half-life, volume of distribution, and elimination rate constant averaged 0.82 hr, 6.5 hr, 4.0 liters/sq m, and 0.25 hr-1, respectively. Noncompartmental parameters such as systemic clearance, mean residence time, and volume of distribution at steady-state averaged 20.9 ml/min/sq m, 7.8 hr, and 7.2 liters/sq m, respectively. A significant relationship between serum glutamic pyruvic transaminase and systemic clearance was observed, with patients having elevated serum glutamic pyruvic transaminase showing slower systemic clearance of etoposide. Systemic clearance, mean residence time, and β-phase half-life of etoposide were significantly lower in those patients who had received cisplatin prior to their Phase II etoposide trial. The average pharmacokinetic values derived from these eight pediatric patients with solid tumors did not differ significantly ...

Pathologic hyperpermeability exists in the spectrum of disease states, including neuro-ischemic, neuro-inflammatory and neuro-oncological. To-date the characterization of disease pathology with T 1 -weighted quantitative dynamic contrast-enhanced magnetic resonance imaging has relied on the study of modeled microvascular parameters such as diseased tissue transvascular flow rates of small molecule paramagnetic imaging agents with short plasma half-lives, based on which it is difficult to assess the specific nature of the disease state. Another type of T 1 -weighted quantitative dynamic contrast-enhanced magnetic resonance imaging involves the use of paramagnetic heavy metal-chelated dendrimer nanoparticles that possess longer plasma half-lives with pre-determined molar relaxivities to quantitatively image concentration of macromolecular contrast agent accumulation over time in hyperpermeable pathology such as solid tumor tissue with the
Postoperative nausea and vomiting (PONV) remains a common complication for both inpatients and outpatients undergoing surgical procedures. PONV is a complex physiologic phenomenon involving multiple neurophysiologic pathways and both central and peripheral receptor mechanisms. The frequently used antiemetics produce dopamine, acetylcholine, histamine, and serotonin receptor blocking properties.1 More recently, the neurokinin (NK)-1 receptor antagonists were also shown to have the potential for both preventing and treating PONV.2 - 7 In this issue of Anesthesia & Analgesia, Gan et al.8 report on rolapitant, a novel NK-1 receptor antagonist with a long elimination half-life value, for the prevention of PONV. This clinical trial was designed as a dose-ranging study involving both placebo and active comparator controls. The authors concluded that rolapitant reduced the incidence of postoperative vomiting in a dose-dependent manner and was superior to placebo at all doses studied. They also noted ...
If an alien visited Earth and wanted to capture a summary of video gaming, theyd quickly become aware of Half-Life. The series is far from foreign to the hearts of most gamers, and the products of the Half-Life universe - both the Half-Life and Portal series - remain some of the highest rated games by critics. However, the series has become even more iconic for its unreleased sequel, Half-Life 3.. Half-Life 3, or perhaps more appropriately Half-Life 2: Episode Three, has become a notable case of anticipation and speculation. Years after the latest instalment to the Half-Life series, the game is yet to even get a mention by developer Valve, even though the episodic sequels to Half-Life 2 were announced as a triology. In this article, well take a look at the story of Half-Life, both in the games released already and whats speculated for the future.. Be warned: spoilers ahead! (more…). ...
Distribution: Following drug administration, a 6 to 8 hour tissue distribution phase is observed. This is followed by a much more gradual decline in the serum concentration of the drug, which is dependent on the elimination of digoxin from the body. The peak height and slope of the early portion (absorption/distribution phases) of the serum concentration-time curve are dependent upon the route of administration and the absorption characteristics of the formulation. Clinical evidence indicates that the early high serum concentrations do not reflect the concentration of digoxin at its site of action, but that with chronic use, the steady-state post-distribution serum concentrations are in equilibrium with tissue concentrations and correlate with pharmacologic effects. In individual patients, these post-distribution serum concentrations may be useful in evaluating therapeutic and toxic effects. Digoxin is concentrated in tissues and therefore has a large apparent volume of distribution ...

Hydrolysis Data available for the structurally and functionally similar read across chemicals has been reviewed to determine the half-life of the test chemical. The studies are as mentioned below: The half-life of the test chemical was determined at different pH range. The study was performed according to OECD Guideline 111 (Hydrolysis as a Function of pH) at a temperature of 50°C (ranges from 49-51°C) and pH of 4, 7 and 9, respectively. Initial test chemical concentration used for the study was 100 mg/l. Experiment was performed in 2 replicates. The test substance has no activity of hydrolysis and thus was reported to be hydrolytically stable at pH 4, 7 and 9, respectively at a temperature of50⁰C for 5 days. The half-life value of test chemical was determined to be , 5 days at pH 4, 7 and 9, respectively & at a temperature of 50⁰C. Thus based on this, test chemical is considered to be not hydrolysable. In an another study, the half-life and hydrolysis rate constant was determined of the ...
Radiolabeling is a technique used to track the passage of a molecule that incorporates a radioisotope through a reaction, metabolic pathway, cell, tissue, organism, or biological system. The reactant is labeled by replacing specific atoms by their isotope. Replacing an atom with its own radioisotope is an intrinsic label that does not alter the structure of the molecule. Alternatively, molecules can be radiolabeled by chemical reactions that introduce an atom, moiety, or functional group that contains a radionuclide. For example, radio-iodination of peptides and proteins with biologically useful iodine isotopes is easily done by an oxidation reaction that replaces the hydroxyl group with iodine on tyrosine and histadine residues. Another example is to use chelators such DOTA that can be chemically coupled to a protein; the chelator in turn traps radiometals thus radiolabeling the protein. This has been used for introducing Yttrium-90 onto a monoclonal antibody for therapeutic purposes and for ...
Buy Ractopamine is an animal growth promotant. The effects of the beta-agonist ractopamine, use in finishing swine and cattle to improve carcass quality and performance. Moreover Feeding RAC to late-finishing swine resultes in faster growing, more efficient animals with increased boneless subprimal yields, and it had little effect on pork juiciness and flavor.. Also Ractopamine is rapid in intake, with the mean peak plasma concentration of 41.2 ng/ml occurring after an average of 0.6 h.

We report on extensive experimental studies on thin film, single crystal, and ceramics of multiferroic bismuth ferrite BiFeO3 using differential thermal analysis, high-temperature polarized light microscopy, high-temperature and polarized Raman spectroscopy, high-temperature x-ray diffraction, dc conductivity, optical absorption and reflectivity, and domain imaging, and show that epitaxial (001) thin films of BiFeO3 are clearly monoclinic at room temperature, in agreement with recent synchrotron studies but in disagreement with all other earlier reported results. We report an orthorhombic order-disorder beta phase between 820 and 925 (±5) °C, and establish the existence range of the cubic gamma phase between 925 (±5) and 933 (±5) °C, contrary to all recent reports. We also report the refined Bi2O3-Fe2O3 phase diagram. The phase transition sequence rhombohedral-orthorhombic-cubic in bulk [monoclinic-orthorhombic-cubic in (001)BiFeO3 thin film] differs distinctly from that of BaTiO3. The ...

The half-life of knowledge or half-life of facts is the amount of time that has to elapse before half of the knowledge or facts in a particular area is superseded or shown to be untrue. These coined terms belong to the field of quantitative analysis of science known as scientometrics. These ideas of half-life applied to different fields differ from the concept of half-life in physics in that there is no guarantee that the knowledge or facts in areas of study are declining exponentially. It is unclear that there is any way to establish what constitutes knowledge in a particular area, as opposed to mere opinion or theory. An engineering degree went from having a half life of 35 years in ca. 1930 to about 10 years in 1960.[1] A Delphi Poll showed that the half life of psychology as measured in 2016 ranged from 3.3 to 19 years depending on the specialty, with an average of a little over 7 years.[2] It has also been used in Christian missiology to increase the effectiveness of their teachings.[3] ...
GHRH (growth hormone releasing hormone) is produced in the hypothalamus. Its pulsatile release from the hypothalamus triggers a pulsatile release of GH from the pituitary gland. GHRH has a very short half-life of only a few minutes (half-life = the time required to remove half of the substance from the blood. The shorter the half- life, the more rapidly the substance is removed from the body, and the less its effect on the body). The first 29 amino acids of GHRH is the active segment. They are available as a manufactured peptide called Sermorelin. Sermorelin was further modified to increase its half-life to 30 minutes. This is called CJC 1295. CJC-1295 was further modified by adding DAC (Drug Affinity Complex) to it. DAC binds to a blood protein called albumin, which increases its half-life to 8 days. It is called CJC 1295 + DAC. CJC 1295 can also be compounded in a non-DAC form which mimics a more normal physiologic GH spike each night. The longer half-life from the DAC binding to albumin means ...

The most frequently reported adverse events (AEs) were dermatitis contact, back pain, blood pressure decrease, headache and nausea. The majority of AEs were mild in intensity with few moderates and no severe. No increase in AEs was observed in relation to increasing dose. The PK analysis indicated that the AUC and Cmax increase in a more than dose proportional manner over the 25 to 600 mg doses with the AUC and Cmax at 600 mg being respectively 62- and 92-fold higher than at the 25 mg dose. Proportionality in AUC and Cmax was noticed between the 600 and 800 mg doses. The elimination half-life, for all cohorts, was ca. 5 hours. At the 400 mg dose, there was no significant food-effect on any of the measured PK parameters. There was a ritonavir-effect as the PK parameters for terminal half-life, AUC and Cmax were 3-, 19- and 6-fold higher, respectively, when 25 mg VCH-286 was co-administered with 100 mg ritonavir. This observation is consistent with the fact that VCH-286 is a CYP3A4 substrate. ...
To the editor: The paper on naloxone by Dr. Martin (Ann Intern Med 85:765-768, 1976) states on page 767, Naloxone has a relatively short duration of action. The serum half-life of naloxone is just over an hour (17) and the half-life of commonly used clinical doses may be only several hours (18, 19).. By definition, the half-life of any substance X is constant and most certainly does not depend on the initial dose. This is such a serious conceptual error that it undermines my confidence in the whole paper. ...

The most common price range of Cialis falls between $5 per pill for lower doses (2.5 mg and 5 mg) and $20 to $30 per pill for higher doses (10 mg and 20 mg).. Most doctors prescribe Cialis at a typical strength of 10 mg daily. Now, a bottle of 30 pills with 10 mg Cialis approximately costs $650 to $1,800, depending on where you buy it.. Cialis does cost significantly higher compared to its counterparts. Viagra costs up to $1,400 or less per bottle, while Levitra is around $500 per bottle.. Cialis belongs to the same drug family as Viagra and Levitra. It works just the same as those two, and all of them are equally effective in treating erectile dysfunction.. So, why is it that Cialis is such a pricey drug compared to them?. ...

Fazadinium was administered as an intravenous bolus of 0.5 or 1 mg/kg to nine patients during neurolept-anaesthesia. Continuous recording of neuromuscular activity and serial collection of blood samples for drug assay allowed the relationship between neuromuscular blockade and plasma fazadinium concentration to be studied. Pharmacokinetic analysis demonstrated high plasma clearances (221 and 185 ml/min), and short terminal half-lives, (30 and 50 min), for the two doses of the drug. Mean plasma concentrations at 10 and 50% recovery were 1.42 and 0.88 micrograms/ml respectively, demonstrating that the potency of fazadinium is approximately half that of tubocurarine and one eighth that of pancuronium. In addition, the relationship between plasma concentration and depression of neuromuscular activity during spontaneous recovery from the relaxant is described.
I hope you dont me saying I think you have it wrong with the knowledge economy. David mentioned the singularity - I dont think the knowledge economy can take us that far. You see there is a fundamental limit, the capacity of the human brain. To train an expert takes an ever increasing time, and his expertise has an ever decreasing half-life. We need to leverage the human capacity for understanding enormously or humanity will be overwhelmed by its own knowledge. We already are talking of a web that is data rich and information poor. There is a great danger of that situation becoming worse, of attention and understanding becoming absolute limiting factors. Im not convinced that the knowledge worker is the owner of the future, Ive already had to reinvent myself often enough, thanks. (And do you know how soul destroying it is to create useful niche interfaces with short half-lives - that get replaced eventually with something cheaper and far better?) We need a world that humans can find a ...
