Quantifying the effect of changes in the hemodialysis prescription on effective solute removal with a mathematical model. (1/173)

One potential benefit of chronic hemodialysis (HD) regimens of longer duration or greater frequency than typical three-times-weekly schedules is enhanced solute removal over a relatively wide molecular weight spectrum of uremic toxins. This study assesses the effect of variations in HD frequency (F: per week), duration (T: min per treatment), and blood/dialysate flow rates (QB/QD: ml/min) on steady-state concentration profiles of five surrogates: urea (U), creatinine (Cr), vancomycin (V), inulin (I), and beta2-microglobulin (beta2M). The regimens assessed for an anephric 70-kg patient were: A (standard): F = 3, T = 240, QB = 350, QD = 600; B (daily/short-time): F = 7, T = 100, QB = 350, QD = 600; C/D/E (low-flow/long-time): F = 3/5/7, T = 480, QB = 300, QD = 100. HD was simulated with a variable-volume double-pool model, which was solved by numerical integration (Runge-Kutta method). Endogenous generation rates (G) for U, Cr, and beta2M were 6.25, 1.0, and 0.17 mg/min, respectively; constant infusion rates for V and I of 0.2 and 0.3 mg/min, respectively, were used to simulate middle molecule (MM) G values. Intercompartment clearances of 600, 275, 125, 90, and 40 ml/min were used for U, Cr, V, I, and beta2M, respectively, For each solute/regimen combination, the equivalent renal clearance (EKR: ml/min) was calculated as a dimensionless value normalized to the regimen A EKR, which was 13.4, 10.8, 6.6, 3.7, and 4.8 ml/min for U, Cr, V, I, and beta2M, respectively. For regimens B, C, D, and E, respectively, these normalized EKR values were U: 1.04, 0.96, 1.58, and 2.22; Cr: 1.03, 1.08, 1.80, and 2.55; V: 1.06, 1.32, 2.21, and 3.12; I: 1.05, 1.54, 2.57, and 3.62; beta2M: 1.00, 1.27, 1.73, and 2.19. The extent of post-HD rebound (%) was highest for regimens A and B, ranging from 16% (urea) to 50% (inulin), and lowest for regimen E, ranging from 6% (urea) to 28% (beta2M). The following conclusions can be made: (1) Relative to a standard three-times-weekly HD regimen of approximately the same total (weekly) treatment duration, a daily/short-time regimen results in modest (3 to 6%) increases in effective small solute and MM removal. (2) Relative to a standard three-times-weekly HD regimen, a three-times-weekly low-flow/long-time regimen results in comparable effective small solute removal and progressive increases in MM and beta2M removal. A daily low-flow/long-time regimen substantially increases the effective removal of all solutes.  (+info)

Pharmacokinetics of new calcium channel antagonist clevidipine in the rat, rabbit, and dog and pharmacokinetic/pharmacodynamic relationship in anesthetized dogs. (2/173)

Clevidipine is a new vascular selective calcium channel antagonist of the dihydropyridine type, structurally related to felodipine. Clinical trials have shown that the drug can be used to effectively control the blood pressure in connection with cardiac surgical procedures. The compound is tailored to be a short-acting drug and, due to incorporation of an ester linkage into the drug molecule, clevidipine is rapidly metabolized by ester hydrolysis. The pharmacokinetics of clevidipine and its primary metabolite, H 152/81, were studied in rats, rabbits, and dogs. In addition, the influence of the pharmacokinetics on the effect on mean arterial blood pressure was evaluated in anesthetized dogs. Compartmental nonlinear mixed effect regression analysis was used to calculate the population mean and individual pharmacokinetics of clevidipine, whereas nonlinear regression analysis of individual data was used to determine the pharmacokinetics of the primary metabolite. A linked Emax model was fitted to the individual pharmacodynamic/pharmacokinetic data in dogs. According to the results, clevidipine is a high-clearance drug with a relatively small volume of distribution, resulting in an extremely short half-life in all species studied. The median initial half-life of the individual value (Bayesian estimates) is 12, 20, and 22 s in the rabbit, rat, and dog, respectively. The primary metabolite is a high-clearance compound in the dog, whereas it is a low-clearance compound in the rat. A significant gender difference in the clearance of the metabolite was observed in the rat. The mean maximum reduction in arterial blood pressure is 38 +/- 12% (Emax) and is achieved at 85 +/- 46 nM (EC50). The half-life for reaching equilibrium between the central and the effect compartment (T1/2ke0) is 47 +/- 49 s.  (+info)

Which linear compartmental systems can be analyzed by spectral analysis of PET output data summed over all compartments? (3/173)

General linear time-invariant compartmental systems were examined to determine which systems meet the conditions necessary for application of the spectral analysis technique to the sum of the concentrations in all compartments. Spectral analysis can be used to characterize the reversible and irreversible components of the system and to estimate the minimum number of compartments, but it applies only to systems in which the measured data can be expressed as a positively weighted sum of convolution integrals of the input function with an exponential function that has real-valued nonpositive decay constants. The conditions are met by compartmental systems that are strongly connected, have exchange of material with the environment confined to a single compartment, and do not contain cycles, i.e., there is no possibility for material to pass from one compartment through two or more compartments back to the initial compartment. Certain noncyclic systems with traps, systems with cycles that obey a specified loop condition, and noninterconnected collections of such systems also meet the conditions. Dynamic positron emission tomographic data obtained after injection of a radiotracer, the kinetics of which can be described by any model in the class of models identified here, can be appropriately analyzed with the spectral analysis technique.  (+info)

Single- and multifrequency models for bioelectrical impedance analysis of body water compartments. (4/173)

The 1994 National Institutes of Health Technology Conference on bioelectrical impedance analysis (BIA) did not support the use of BIA under conditions that alter the normal relationship between the extracellular (ECW) and intracellular water (ICW) compartments. To extend applications of BIA to these populations, we investigated the accuracy and precision of seven previously published BIA models for the measurement of change in body water compartmentalization among individuals infused with lactated Ringer solution or administered a diuretic agent. Results were compared with dilution by using deuterium oxide and bromide combined with short-term changes of body weight. BIA, with use of proximal, tetrapolar electrodes, was measured from 5 to 500 kHz, including 50 kHz. Single-frequency, 50-kHz models did not accurately predict change in total body water, but the 50-kHz parallel model did accurately measure changes in ICW. The only model that accurately predicted change in ECW, ICW, and total body water was the 0/infinity-kHz parallel (Cole-Cole) multifrequency model. Use of the Hanai correction for mixing was less accurate. We conclude that the multifrequency Cole-Cole model is superior under conditions in which body water compartmentalization is altered from the normal state.  (+info)

Isotope dilution spaces of mice injected simultaneously with deuterium, tritium and oxygen-18. (5/173)

The isotope dilution technique for measuring total body water (TBW), and the doubly labelled water (DLW) method for measuring energy expenditure, are both sensitive to small variations in the ratio of the hydrogen to oxygen-18 dilution space. Since the dilution space ratio varies between individuals, there has been much recent debate over what causes this variability (i.e. physiological differences between individuals or analytical error in the isotope determinations), and thus which values (individual or a population mean dilution space ratio) should be employed for TBW and DLW calculations. To distinguish between physiological and analytical variability, we injected 15 non-reproductive and 12 lactating mice (Mus musculus, outbred MF1) simultaneously with deuterium, tritium and oxygen-18. The two hydrogen labels were administered and analysed independently, therefore we expected a strong correlation between dilution space ratios based on deuterium and tritium if most of the variation in dilution spaces was physiological, but only a weak correlation if most of the variation was analytical. Dilution spaces were significantly influenced by reproductive status. Dilution spaces expressed as a percentage of body mass averaged 15.7 % greater in lactating mice than in non-reproductive mice. In addition, the hydrogen tracer employed had a significant effect (deuterium spaces were 2.0 % larger than tritium spaces). Deuterium and tritium dilution spaces, expressed as a percentage of body mass, were highly correlated. Dilution space ratios ranged from 0.952 to 1. 146 when using deuterium, and from 0.930 to 1.103 when using tritium. Dilution space ratios based on deuterium and tritium were also highly correlated. Comparison of standard deviations of the dilution space ratio based on deuterium in vivo and in vitro indicated that only 4.5 % of the variation in the dilution space ratios observed in the mice could be accounted for by analytical variation in the deuterium and oxygen-18 analyses. Although our results include data which were outside the limits previously regarded as biologically possible, the correlations that we detected strongly suggest that variation in the observed dilution space ratio was mostly physiological rather than analytical.  (+info)

Effect of epinephrine on lidocaine clearance in vivo: a microdialysis study in humans. (6/173)

BACKGROUND: Local anesthetic nerve block prolonged by epinephrine is thought to result from local vasoconstriction and consequent decreased local anesthetic clearance from the injection site. However, no study has yet confirmed this directly in humans by measuring tissue concentrations of local anesthetic over time. In addition, recent studies have shown that the alpha2-adrenergic receptor agonist, clonidine, also prolongs nerve block without altering local anesthetic clearance. Because epinephrine is also an alpha2-adrenergic receptor agonist, it is possible that epinephrine prolongs local anesthetic block by a pharmacodynamic mechanism and not a pharmacokinetic one. This study was designed to address this issue. METHODS: Microdialysis probes were placed adjacent to the superficial peroneal nerve in both feet of eight volunteers. Plain lidocaine (1%) was injected along one peroneal nerve and lidocaine with epinephrine (2.5 microg/ml) was injected along the other nerve in a double-blinded, randomized manner. The concentration of lidocaine in tissue was measured at 5-min intervals, and sensory block and cutaneous blood flow were assessed by laser Doppler at 10-min intervals for 5 h. The resulting data for lidocaine concentration versus time were fit to a two-compartment model using modeling software. RESULTS: Epinephrine prolonged sensory block by decreasing local blood flow and slowing clearance. There was no evidence of a pharmacodynamic effect of epinephrine. CONCLUSION: Although epinephrine activates alpha2-adrenergic receptors, its mechanism for prolonging the duration of local anesthetic block rests on its ability to decrease local anesthetic clearance and not on a pharmacodynamically mediated potentiation of local anesthetic effect.  (+info)

Water diffusion, T(2), and compartmentation in frog sciatic nerve. (7/173)

A potential relationship between structural compartments in neural tissue and NMR parameters may increase the specificity of MRI in diagnosing diseases. Nevertheless, our understanding of MR of nerves and white matter is limited, particularly the influence of various water compartments on the MR signal is not known. In this study, components of the (1)H transverse relaxation decay curve in frog peripheral nerve were correlated with the diffusion characteristics of the water in the nerve. Three T(2) values were identified with nerve. Water mobility was found to be unrestricted on the timescale of 100 msec in the component of the signal with the intermediate T(2) time, suggesting some contribution from the interstitial space to this T(2) component. Restricted diffusion was observed in the component with the longest T(2) time, supporting the assignment of at least part of the spins contributing to this component to an intracellular compartment. The observed nonexponential behavior of the diffusion attenuation curves was investigated and shown to be potentially caused by the wide range of axon sizes in the nerve.

Physiologically based toxicokinetic modeling of inhaled ethyl tertiary-butyl ether in humans. (8/173)

A physiologically based toxicokinetic (PBTK) model was developed for evaluation of inhalation exposure in humans to the gasoline additive, ethyl tertiary-butyl ether (ETBE). PBTK models are useful tools to relate external exposure to internal doses and biological markers of exposure in humans. To describe the kinetics of ETBE, the following compartments were used: lungs (including arterial blood), liver, fat, rapidly perfused tissues, resting muscles, and working muscles. The same set of compartments and, in addition, a urinary excretion compartment were used for the metabolite tertiary-butyl alcohol (TBA). First order metabolism was assumed in the model, since linear kinetics has been shown experimentally in humans after inhalation exposure up to 50 ppm ETBE. Organ volumes and blood flows were calculated from individual body composition based on published equations, and tissue/blood partition coefficients were calculated from liquid/air partition coefficients and tissue composition. Estimates of individual metabolite parameters of 8 subjects were obtained by fitting the PBTK model to experimental data from humans (5, 25, 50 ppm ETBE, 2-h exposure; Nihlen et al., Toxicol. Sci., 1998; 46, 1-10). The PBTK model was then used to predict levels of the biomarkers ETBE and TBA in blood, urine, and exhaled air after various scenarios, such as prolonged exposure, fluctuating exposure, and exposure during physical activity. In addition, the interindividual variability in biomarker levels was predicted, in the eight experimentally exposed subjects after a working week. According to the model, raising the work load from rest to heavy exercise increases all biomarker levels by approximately 2-fold at the end of the work shift, and by 3-fold the next morning. A small accumulation of all biomarkers was seen during one week of simulated exposure. Further predictions suggested that the interindividual variability in biomarker levels would be higher the next morning than at the end of the work shift, and higher for TBA than for ETBE. Monte Carlo simulations were used to describe fluctuating exposure scenarios. These simulations suggest that ETBE levels in blood and exhaled air at the end of the working day are highly sensitive to exposure fluctuations, whereas ETBE levels the next morning and TBA in urine and blood are less sensitive. Considering these simulations, data from the previous toxicokinetic study and practical issues, we suggest that TBA in urine is a suitable biomarker for exposure to ETBE and gasoline vapor.  (+info)

The term electrolyte refers to the anions and cations that are distributed throughout the fluid compartments of the body. They are distributed in such a way that within a given compartment, the blood plasma for example, electrical neutrality is always maintained, with the anion concentration exactly balanced by the cation concentration.. The cationic electrolytes of the extracellular fluid include sodium, potassium, calcium, and magnesium, and these are electrically balanced by the anions, chloride, bicarbonate, and proteins, along with relatively low concentrations of organic acids, phosphate, and sulphate. Most of the electrolytes are categorized nutritionally as macrominerals and are discussed below.. One of the more important factors determining the distribution of water among the water compartments of the body is osmotic pressure. The term osmosis is used to describe the movement of water from a solution with higher water concentration (lower solute) toward the solution with lower water ...

Results from the EQC (Equilibrium Criterion) Levels I and III distribution models (Mackay, 2001) show that because of its low water solubility, DIUP is not expected to partition to the water compartment (see Section 4.2.2). However, abiotic degradation of any trace amounts of DIUP which may be present in aquatic environments is unlikely to occur at a significant rate based on modeled data. The HYDROWIN model, a subroutine within the USEPA (2000) computer program, estimates a hydrolysis half-life for DIUP of 4.2 years at pH 7 (25°C) and 152.4 days at pH 8 (25°C). ...
Reconstruction of the electrical sources of human EEG activity at high spatio-temporal accuracy is an important aim in neuroscience and neurological diagnostics. Over the last decades, numerous studies have demonstrated that realistic modeling of head anatomy improves the accuracy of source reconstruction of EEG signals. For example, including a cerebro-spinal fluid compartment and the anisotropy of white matter electrical conductivity were both shown to significantly reduce modeling errors. Here, we for the first time quantify the role of detailed reconstructions of the cerebral blood vessels in volume conductor head modeling for EEG. To study the role of the highly arborized cerebral blood vessels, we created a submillimeter head model based on ultra-high-field-strength (7T) structural MRI datasets. Blood vessels (arteries and emissary/intraosseous veins) were segmented using Frangi multi-scale vesselness filtering. The final head model consisted of a geometry-adapted cubic mesh with over ...

The body is made up of fluid compartments. Most water is in our cells and is called intracellular fluid. The rest is the extracellular fluid or ECF. This is made up of the interstitial fluid (between cells in our tissues) and the plasma in our blood. The interstitial fluid and plasma run into each other in the leaky capillary beds. When we eat a salty meal the osmolarity of our blood rises. This then directly raises the osmolarity of our interstitial fluid.. Water in our cells is separated from interstitial fluid by plasma membrane. The main way that water can escape is by osmosis. After a salty meal, the increased osmolarity of the interstitial fluid causes water to leak out from the cells. This ultimately boosts our blood volume, diluting the saltiness of the blood.. The amount of sodium in our blood needs to be in a tight range between 136-146 mmol/L. If our blood sodium gets too low then the osmolarity of the interstitial fluid is lower than that inside the cells and water seeps into the ...
3 Fluid compartments are separated by membranes that are freely permeable to water - but impermeable to solutes. Movement of fluids is due to: - hydrostatic pressure differentials - osmotic pressure differentials
This report provides an initial characterization of a cell line derived from epithelial cells lining the porcine distal male reproductive duct. This vas deferens epithelial cell line, PVD9902, has been cultured in vitro successfully for ,4 yr and has maintained many functional characteristics of freshly isolated cells. Molecular studies have verified the gender and species of origin. The presence of various epitopes (detected using immunocytochemical procedures) has demonstrated the epithelial nature of the cells. Functional data have suggested an electrically tight, well-differentiated epithelial monolayer capable of ion transport and separation of fluid compartments. PVD9902 cells have retained responsiveness to all neurotransmitters shown previously to be effective in increasing Isc across primary cell cultures in vitro and native epithelium ex vivo. Thus PVD9902 cells provide great promise as a tool to elucidate ductal epithelial mechanisms that contribute to male fertility.. The ...
A transesophageal echocardiographic scanner includes a rotatable transducer for rotating the image plane of the scanner. The transducer is a circular shaped array of parallel oriented elements which may be operated as a phased or linear array. The transducer is mounted on a bell-shaped backing box with a conical interior surface that directs reverberations from the back of the transducer into damping material which fills the box. The transducer is located in a fluid compartment which is divided by a cover member into an ultrasonic transmission region between the emitting surface of the transducer and the cover, and an adjacent bubble trap region into which bubbles may pass and preferentially remain.

The amount of growth we capture by measuring the amount of 18O in the DNA extract may not represent the true amount of growth (Figure 1b). This may be for two main reasons. The first is that extracellular water is not the sole source of oxygen for DNA. Rather, anywhere from 4% to 70% of oxygen in DNA may come from metabolic water (Kreuzer-Martin et al., 2005, 2006; Li et al., 2016) or oxygenated carbon sources (Qu et al., 2020). Our model refers to this propensity toward using extracellular water or carbon sources rather than intracellular water or carbon sources as the oxygen contribution to DNA as H2Ocont, which is the fraction of extracellular water used for DNA synthesis. This value is commonly assumed to be one (i.e., 100% of new DNA oxygen is derived from extracellular water) in reported CUE values (Spohn et al., 2016a, 2016b; Geyer et al., 2019; Zheng et al., 2019), but in practice may be as low as 30% in fast-growing bacteria (Chaney et al., 1972; Hungate et al., 2015; Li et al., 2016). ...
4-aminophenol is soluble (6500 mg/L) and is inherently biodegradable in water with pre-adapted sludge. It has a low capacity to volatilise from solution to the air (Henrys law constant of 8.954E-005 Pa m3/mol-1) and undergoes rapid phototransformation in the atmosphere (half-life of 1.7 hours in the presence of hydroxyl radicals at1.5X10+6 hydroxyl radicals per cu assuming 12 hours daylight). The partitioning coefficient (log Kow = -0.09) indicates that 4-aminophenol does not have a high potential for adsorption to soil or sediment (log Koc = 0.59). It has a low potential for bioaccumulation in aquatic and terrestrial habitats (BCF ,=0.46 L/kg). Assuming predominate emissions to the water compartment, Mackay Level III fugacity predictions estimate 1.61%, 98.2%, 0.18% and 3.24e-007 % partitioning in the soil, water, sediment and air compartments, respectively. 4 -aminophenol is amphoteric with both amine and hydroxyl functional groups; pKa values for these groups are 5.48 and 10.46, ...
In this thesis Reverse Electrodialysis (RED) is central. A RED stack comprises of alternating series of cation exchange membranes (CEMs) and anion exchange membranes (AEMs), with seawater and river water compartments between these membranes.. From the salinity gradient, energy is harvested while controlling the mixing of seawater and river water. Membranes allow selective transport of cations (CEM) and anions (AEM). A voltage difference is created due to the difference in salinity across the membrane. At the electrodes redox reactions are used, to convert ionic transport into electrical transport, to power a device.. We came up with creative strategies to prevent fouling, says Jordi Moreno. The most high-profile idea concerned the concept of breathing cells. We brought this proof of principle - confirmed earlier in lab environments by dr. ir. David Vermaas - a decisive step further. The stack is now automatically operable which is practically relevant.. In the breathing cell concept, instead ...
Eggs should be turned over the pointed end three times a day so that the embryos dont stick to the shell. This should be done to all eggs that are intended for hatching, even if they are just being stored in boxes. It is best to place the eggs with the tip pointing inwards. Once the eggs have been put in leave the incubator lid on all the time unless you are turning the eggs. In many incubators, there will be two water compartments in the middle.

After years of research, Entrinsic Health Solutions has evaluated each amino acid for its absorptive capabilities, tight barrier function and cellular regeneration to create a proprietary Amino Acid Coupled Transport (A2CT) technology. The select amino acids and electrolytes (sodium and potassium) in enterades® Advanced Oncology Formula help to rebuild the damaged GI absorptive structures, protect the GI by tightening the gut barrier, and provide total body hydration.. Amino acids in enterade® do not have the secretory effect of chloride and will not have a deleterious effect on diarrhea. Amino acids in enterade® have shown to reduce paracellular permeability, therefore reducing antigenic translocation. These select amino acids do not dissociate from sodium in the vascular space, as they carry the electrolyte and fluids from the vascular into the intracellular and interstitial space, providing hydration of all three fluid compartments.. The enterade® Advanced Oncology Formula was created ...
With all this pain and suffering being the zeitgeist of successful bike racing, some things may just seem too easy - and cheap - to be believed. Your honor, I give you exhibit A: a man forms a new Salt Lake while exercising, feels like crap afterward and, surprise of surprises, craves salt. So he ingests salt and within moments feels better. A true entrepreneur here would waste no time getting on cable to hawk the miracle Egyptian muscle cramp vaccine for the low, low one-time-only price of $49.99, including a glass trophy case for displaying all the hardware you can now expect to be dragging home.. Truth is, dehydration and excessive sodium loss are the most common causes of muscle cramps in athletes. Water lost via sweat comes from all fluid compartments of the body, including the blood. If fluid losses are not matched by consumption during exercise, the body becomes dehydrated and blood volume decreases. The decrease in blood volume means that the heart has to work harder to pump blood to ...

Ingestion of creatine (Cr) and glycerol (Gly) has been reported to be an effective method in expanding water compartments within the human body, attenuating the rise in heart rate (HR) and core temperature (Tcore) during exercise in the heat. Despite these positive effects, a substantial water retention could potentially impair endurance performance through increasing body mass (BM) and consequently impacting negatively on running economy (RE). The objective of the present study was to investigate the effects of a combined Cr and Gly supplementation on thermoregulatory and cardiovascular responses and RE during running for 30 min at speed corresponding to 60% of maximal oxygen uptake in hot and cool conditions. Cr·H2O (11.4 g), Gly (1 g·kg-1 BM) and Glucose polymer (75 g) were administered twice daily to 15 male endurance runners during a 7-day period.
Stability Phototransformation in air (4-MHHPAc): Half-life for reaction with photochemically-produced hydroxyl radicals estimated to be 30.1 hours. Hydrolysis: Half life - at ph 4: 1.43 minutes at 20 deg C; 2.04 minutes at 30 deg C and 0.692 minutes at 50 deg C. at ph 7: 1.90 minutes at 20 deg C; 1.26 minutes at 30 deg C and 0.327 minutes at 50 deg C. at ph 9: 1.27 minutes at 20 deg C; 1.18 minutes at 30 deg C and 0.233 minutes at 50 deg C. As a result of this rapid hydrolysis, in the water compartment, the environmental fate of the acid degradation product (4 -MHHPAc) should be considered. Biodegradation Ready biodegradability in water: 2% in 28 days Bioaccumulation The potential for bioaccumulation of 4-MHHPAc (the hydrolysis produc of 4-MHHPA) is low, less than 2.4 L/Kg, as expected from low values of log Kow for both substances.

An understanding of osmotic shifts between the ECF and ICF is fundamental to understanding disorders of fluid balance. Iso-osmolality is generally maintained between fluid compartments. Because the cell membrane is water-permeable, abnormal fluid shifts occur if the concentration of solutes that cannot permeate the cell membrane in the ECF does not equal the concentration of such solutes in the ICF. Thus, NaCl, mannitol, and glucose (in the setting of hyperglycemia) remain restricted to the ECF space and contribute effective osmoles by obligating water to remain in or be drawn into the ECF compartment. In contrast, a freely permeable solute such as urea does not contribute effective osmoles because it is not restricted to the ECF and readily crosses cell membranes. Tonicity, or effective osmolality, differs from measured osmolality in that it accounts only for osmotically active impermeable solutes rather than all osmotically active solutes, including those that are permeable to cell membranes. ...
The introduction of transporter transfected cell lines capable of forming tight cell layers has facilitated the investigation of single transporter interactions on monolayers. Epithelial-like pig kidney cell line (LLC-PK1) forms a tight monolayer on suitable transwell inserts and separates the two fluid compartments above and below it. Transporters present in the cell membrane can have crucial influence on material traffic between the two compartments. The difference between efflux ratios of the transfected and parental cell lines is regarded as a sign of transporter mediated active uptake or efflux process.. SOLVOs single transfectant LLC-PK1 cell lines (BCRP) are excellent tools to investigate specific transporter interactions for medium to high permeability test articles. These service assays are offered in two modes, inhibitor and substrate assessment. (In the inhibitor assessment experiments the effect of the test articles on the transport of the reporter substrate is measured).. ...

Nephrogenic Systemic Fibrosis is a rare condition appearing only in patients with severe renal impairment or failure and presents with dermal lesions and involvement of internal organs. Although many cases are mild, an estimated 5 % have a progressive debilitating course. To date, there is no known effective treatment thus stressing the necessity of ample prevention measures. An association with the use of Gadolinium based contrast agents (GBCA) makes Nephrogenic Systemic Fibrosis a potential side effect of contrast enhanced magnetic resonance imaging and offers the opportunity for prevention by limiting use of gadolinium based contrast agents in renal failure patients. In itself toxic, Gadolinium is embedded into chelates that allow its safe use as a contrast agent. One NSF theory is that Gadolinium chelates distribute into the extracellular fluid compartment and set Gadolinium ions free, depending on multiple factors among which the duration of chelates exposure is directly related to the ...

2 -ethylhexyl benzoate (CAS No. 5444 -75 -4) is hydrolytically stable and therefore abiotic hydrolysis is not a relevant pathway in water. However, the substance is readily biodegradable and will rapidly be removed from natural water compartments as well as from wastewater in sewage treatment plants. The substance has a log Koc of 4.07 indicating potential to adsorb to soil and sediment particles. Calculated value for the Henrys Law constant (25.6 Pa*m3/mol) suggest a gradual evaporation from the water surface into air. In the atmospheric compartment, the substance is susceptible to indirect photodegradation. The estimated half time for the reaction with OH-radicals is 33.4 hours (24h day; OH-concentration: 0.5E+06 OH/cm3). Due to its low water solubility (0.4 mg/L in aqua bidest), ready biodegradability and considerable adsorption to soil and sediment particles (log Koc = 4.29), only low concentrations of 2-ethylhexyl benzoate are expected to be released into the aquatic environment. The ...
Application of bioelectrical impedance analysis and anthropometry as interchangeable methods to assess body composition of sportspersons.
Osmostic diuretics produce a diuresis of water rather than a diuresis of sodium. The body does not metabolize osmotic diuretics. Instead, the drug molecules are not reabsorbed in the kidney tubules. This greatly affects the tonicity of every part of the kidney tubules through which the glomerular filtrates pass. By the process of osmosis, the drug molecules draw an increased amount of water from the interstitial fluid compartment. The result is that a great volume of urine is produced (water diuresis). It just so happens that sodium is contained in that urine and is subsequently removed from the body. Thus, the osmotic diuretics indirectly produce a removal of sodium from the body. Following is one example of an osmotic diuretic: Mannitol. Mannitol is used to prevent acute renal (kidney) failure, evaluate kidney functioning,​ treat glaucoma (by the reduction of intraocular pressure), promote the urinary excretion of toxic substances (diuresis in certain drug intoxications) and reduce ...

Biological barriers are indispensable for the integrity and function of many vertebrate organs. The barrier function is based on intercellular protein complexes of the plasma membrane which form paracellular diffusion barriers and separate internal and external fluid compartments, an indispensable prerequisite for every organ development and function. The review summarizes key characteristics and molecular structure of intercellular junctions (tight junctions and adherens junctions) responsible for cellular barrier formation. One of the most important such cellular barriers is the blood-brain barrier (BBB) which forms an active interface between the circulation and neural tissue. Its principal cellular components are cerebral endothelial cells, pericytes and astrocytes, whose finely tuned interactions are needed for a proper function. The review highlights the most important functions of the BBB including some novel regulatory aspects as well.. ...
It is also seen that Type I and Type II prodrugs can be categorized into Subtypes. For example, Type I has a bioactivation site that is intracellular and it contains subtype of Type IA and Type IB. Type IA is often located in the therapeutic target tissues or cells. Example of this can be diethlstilbestrol diphosphate or 6-mercaptopurine. Then there is Type IB where is located in the metabolic tissues of the liver, Gl mucosal cell, or the lungs and examples for this subtype can be that of heroin, primidone, or captopril.. Furthermore, just like how Type I can be classified into different Subtypes, Type II prodrugs also do the same thing. For instance, Type II has a bioactivation site that is extracellular and it contains subtype of Type IIA, Type IIB, and Type IIC. Type IIA is usually found in the GI fliuds and example of this can be sulfasalazine. Type IIB is found in the systemic circulation and other extracellular fluid compartments. Chloramphenicol succinate or dipivefrin are examples of ...

  • In the human body, solutes vary in different parts of the body, but may include proteins-including those that transport lipids, carbohydrates, and, very importantly, electrolytes. (lumenlearning.com)
  • Plasma travels through the body in blood vessels and transports a range of materials, including blood cells, proteins (including clotting factors and antibodies), electrolytes, nutrients, gases, and wastes. (lumenlearning.com)
  • In fact, the most important means by which the body maintains a balance between water intake and output, as well as a balance between intake and output of most electrolytes in the body, is by controlling the rates at which the kidneys excrete these substances. (123doc.org)
  • This variability of intake is also true for most of the electrolytes of the body, such as sodium, chloride, and potassium. (123doc.org)
  • The kidneys are faced with the task of adjusting the excretion rate of water and elec- trolytes to match precisely the intake of these substances, as well as compensating for excessive losses of fluids and electrolytes that occur in certain disease states. (123doc.org)
  • Some of the electrolytes present in the transcellular fluid are sodium ions, chloride ions, and bicarbonate ions. (wikipedia.org)
  • This compartment has a somewhat different content of salts (electrolytes) than the fluid inside the cells-especially for salts like sodium and potassium. (homedialysis.org)
  • The body contains a large variety of ions, or electrolytes, which perform a variety of functions. (amazonaws.com)
  • 6. Identify the roles of major electrolytes in the body, and how their levels are controlled. (coursehero.com)
  • Electrolytes remain dissolved in the body's fluids as electrically charged particles called ions. (active.com)
  • Electrolytes modulate fluid exchanges between the body's fluid compartments and promote the exchange of nutrients and waste products between cells and the external fluid environment. (active.com)
  • If you consume too much water and not enough electrolytes, your body pulls electrolytes from its cells in order to create the right balance for absorption. (active.com)
  • Distribution of fluids and electrolytes: .Water is by far the most abundant component of the human body. (slideserve.com)
  • Maintenance fluid req is defined as the volume of daily fluid intake which replaces the insensible losses(from breathing and skin ), and at the same time, allows excretion of the daily production of excess solute load(Ur, Cr, electrolytes etc) in a volume of urine that is of an osmolality similar to plasma. (slideserve.com)
