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)

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 ...

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.
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. Fill one of them up but leave the other. In others, there may be only one. Fill this up part of the way, as instructed (in instruction manual)..

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. Fill one of them up but leave the other. In others, there may be only one. Fill this up part of the way, as instructed (in instruction manual).. Eight days into the incubation period it is useful to find out if the eggs are fertilized.You can find out using a candling lamp, a specialist lamp that you can buy either from incubator specialists or an animal feeds merchant. Candling lamps should be used in a very dark spot, otherwise you cant see anything! Hold the lamp against the egg. If you see a dark spot that moves away from the light, youve got a ...
The town is also the most dog-friendly place Ive ever been. Youll frequently see dogs roaming the street, and if one of them decides to lie down in front of the Bean (happens often actually), drivers slow down and move around the pup.

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.

Abstract Fluid overload is associated with adverse outcomes in hemodialysis (HD) patients. Two bedside methods are increasingly utilized to evaluate objectively fluid status-bioimpedance and lung ultrasonography, but there is no available direct, head-to-head comparison of their prognostic significance. Importantly, their predictive abilities have never been tested in a HD popul...

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 ...

There are several types of diuretics. The categories are defined based upon their mechanism of action. a. Osmotic Diuretics. 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 ...
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 ...

Bioelectrical impedance analysis (BIA) is a commonly used method for estimating body composition, and in particular body fat. Since the advent of the first commercially available devices in the mid-1980s the method has become popular owing to its ease of use, portability of the equipment. It is familiar in the consumer market as a simple instrument for estimating body fat. BIA actually determines the electrical impedance, or opposition to the flow of an electric current through body tissues which can then be used to estimate total body water (TBW), which can be used to estimate fat-free body mass and, by difference with body weight, body fat. Many of the early research studies showed that BIA was quite variable and it was not regarded by many as providing an accurate measure of body composition. In recent years technological improvements have made BIA a more reliable and therefore more acceptable way of measuring body composition. Nevertheless, it is not a "gold standard" or reference method. ...
Electrical bioimpedance measurement is widely used today for monitoring body condition. The applications include and go beyond, body composition assessment, nutritional status evaluation, and cancer detection. The modalities for interpreting the impedance information have also developed quickly over the recent decades from single frequency bioimpedance analysis to spectrum and to images.. Bioimpedance is measured by computing the relationship between voltage and current. In a current based bioimpedance measurement system, the stability of current source has a large influence on the performance of the system. This thesis compared three different voltage controlled current sources: enhanced Howland circuit, load-in-the-loop circuit driven by a current conveyor and double operational amplifiers circuit. These circuits were simulated in Multisim and manufactured into prototypes and tested in lab.. Effort has also been made to generate and collect signals with digital-to-analog convertor and ...
Fat mass does not take up water. It brings with it less water percentage than lean mass and so a person with more fat mass will have relatively less % body water. Additional mass as fat contributed relatively less water than additional mass as lean tissue.. Consider a 50 kg individual who is extremely lean. From your numbers, if this individual is 75% water (will will assume lean tissue is 75% water) that is 50 * .75 = 37.5kg water and 12.5kg nonwater body mass.. Now this 50 kg individual puts on 50 kg of fat. The fat is 10% water (from your numbers) so an additional 10 kg of water. This individual its now 47.5kg water and 52.5 nonwater; since this obese person weighs 100 kg now she has 47.5% water, similar to your example. Suppose instead your 50kg person grew up into a 100 kg performance athlete. Still no fat. She is still 75% water because the lean tissue has 75% water.. It has to do with the % water each type of body mass brings with it. This is with no special knowledge; using just the ...

Compartmental localization is defined as the placement of a radiopharmaceutical in a fluid space and maintaining it there long enough to image that fluid space. Since a fluid is defined as a liquid or a gas, the airways of the lungs qualify as a fluid space. The use of Xe-133 gas, Xe-127 gas, or Kr-81m gas as a ventilation agent is therefore a good example of this mechanism. Immediate distribution is to the lungs; since Xe-133 is lipophilic and can cross cell membranes, the gas passively diffuses into pulmonary capillaries and the activity is circulated through the blood stream, permitting cerebral blood flow studies. The tbiol of all these gases in the lungs is ,0.5 min in most patients. Ultimately the activity is cleared from the body through the lungs. Another example of compartmental localization is blood pool imaging using autologous Tc-99m labeled red cells or Tc-99m Human Serum Albumin within the blood pool. The immediate distribution is within the blood pool; ultimately the Tc-99m ...

Stroke is amongthe leading causes of death worldwide and requires immediate care to prevent death or permanent disability. Unfortunately, the current stateof stroke diagnosis is limited to fixed neuroimaging facilities that do not allow rapid stroke diagnosis. Hence, a portable stroke-diagnosis device could assist in the pre-hospital triage of patients. Moreover, such a portable device could also be useful for bedside stroke monitoring of patients in the Neuro Intensive Care Unit (Neuro-ICU) to avoid unnecessary neuroimaging. Recent animal studies and numerical simulations have supported the idea of implementing Electrical Bioimpedance (EBI) in a portable device, allowing non-invasive assessment as a useful tool for the pre-hospital triage of stroke and Traumatic Brain Injury (TBI) patients. Unfortunately, these studies have not reported any results from human subjects in the acute phase of the stroke. The numerical simulations are also based on simple models that sometimes lack necessary ...
Reference data are data that define the set of permissible values to be used by other data fields. Reference data gain in value when they are widely re-used and widely referenced. Typically, they do not change overly much in terms of definition, apart from occasional revisions. Reference data are often defined by standards organizations, such as country codes as defined in ISO 3166-1. Examples of reference data include: Units of measurement Country codes Corporate codes Fixed conversion rates e.g., weight, temperature, and length Calendar structure and constraints Reference data should be distinguished from master data, which represent key business entities such as customers and materials in all their necessary detail (e.g., for customers: number, name, address, and date of account creation). In contrast, reference data usually consist only of a list of permissible values and attached textual descriptions. A further difference between reference data and master data is that a change to the ...
This paper derives new models for describing the spread of biological populations in space and time from classical birth-death-migration processes. The spatial aspect is incorporated using compartmental analysis and is developed for two spatial areas (or compartments). The exact bivariate distributions for such processes are intractable; hence approximating distributions are constructed by matching cumulants. A basic Markovian model with exponential waiting times between births is investigated first. The individual effects of swarming, multiple births, and Erlang distributed waiting times, all of which enhance the biological realism, are investigated. A full model which includes all of these effects is then studied. The models are illustrated with observed data on the spread of the Africanized honey bee in French Guiana. A full model with swarming, with an average of 2.64 colonies per swarming episode, and with waiting times following an Erlang distribution with shape parameter 5 is ...

In neuroradiology, the main use for DWI is to assess for acute ischemia. Increased signal is seen in ischemic tissue a few minutes after arterial occlusion, as extracellular water moves into the intracellular space, which "restricts" its motion causing cytotoxic edema. The ADC value decreases, bottoming out about 1-4 days after the acute insult. Over time, the ADC normalizes first. DWI may remain bright due to T2 shine through from edema in the surrounding tissues. Over time, the DWI normalizes as well ...

  • Author Dr. Engelking covers all the section of physiology relevant for veterinary students including sections on body fluids and compartments, neuromuscular physiology and special senses, respiration, cardiovascular physiology, kidneys. (routledge.com)
  • If there is an excess of water, the kidneys flush it out of the body via the urine, if there is too little water in the body, the kidneys concentrate the urine and the brain sends a signal to drink more water. (cat-world.com.au)
  • There are two kidneys in the body to carry out this essential blood cleansing function. (bway.net)
  • This is the commonest form of shock seen in veterinary patients and can occur secondary to haemorrhage (internal or external) or severe acute fluid loss into the gastrointestinal tract, through the kidneys or into or a "third" space (peritoneal/pleural cavity). (vin.com)
  • Interstitial fluid provides the immediate microenvironment that allows for movement of ions, proteins and nutrients across the cell barrier. (wikipedia.org)
  • When sodium chloride enters the body, it dissociates almost completely into its constituent particles, the ions sodium and chloride. (encyclopedia.com)
  • Dehydration in athletes alters cardiovascular and thermoregulatory function and may inhibit endurance exercise capacity if fluid loss exceeds 2% of bodyweight (BW). (springer.com)
  • If this level of dehydration cannot be prevented when starting from a state of euhydration, then athletes may create a state of hyperhydration by consuming extra fluid prior to exercise. (springer.com)
  • Glycerol-containing beverages create an osmotic gradient in the circulation favouring fluid retention, thereby facilitating hyperhydration and protecting against dehydration. (springer.com)
  • However, ingesting glycerol 0.125 g/kg BW in a volume equal to 5mL/kg BW during exercise will delay dehydration, while adding glycerol 1.0 g/kg BW to each 1.5L of fluid consumed following exercise will accelerate the restoration of plasma volume. (springer.com)
  • The purposes of fluid therapy are to increase blood volume ( dehydration or hypovolemia ), change the content of the blood (such as electrolyte, metabolic and acid disorders), change the distribution, increase excretion. (cat-world.com.au)

  • Nevertheless, this theoretical paradigm contradicts the prevailing view of a body water deficit in excess of 2-3% BM constituting the level of dehydration that can adversely affect performance [ 5 ]. (biomedcentral.com)
  • It is very important that this form of fluid loss can be distinguished from that seen with dehydration. (vin.com)
  • Both hypovolaemic shock and dehydration are treated with fluid therapy but the precise rate of fluid administration chosen depends on which is being treated. (vin.com)
  • To understand the difference between hypovolaemia and dehydration, a brief review of body fluid compartments is necessary. (vin.com)
  • Conversely dehydration represents fluid loss from all three body fluid compartments. (vin.com)
  • Each compartment has a specific solute concentration measured in mOsm/L or osmolarity, which is the number of osmoles within a liter of solution. (osmosis.org)
  • So for example, NaCl splits apart in water to become Na+ and Cl-, so a solution of 1 mmol/L of NaCl is actually 2 mOsm/L. Normally, osmolarity in the intracellular fluid and extracellular fluid is equal. (osmosis.org)
  • When the solvent molecules in the fluid given to your cat are the same concentration (osmolarity) as that of the cells, the balance of water in and out of the cells is is equal (isotonic). (cat-world.com.au)
  • I was thumbing through my physiology notes from a class five years ago and I found the section on Body Fluids. (tanutech.com)

  • Published March 27 in Scientific Reports , a new study co-led by an NYU School of Medicine pathologist reveals that layers of the body long thought to be dense, connective tissues - below the skin's surface, lining the digestive tract, lungs and urinary systems, and surrounding arteries, veins, and the fascia between muscles - are instead interconnected, fluid-filled compartments. (medicalxpress.com)
  • Distributive shock - The body displays generalised inappropriate vasodilation leading to alteration in distribution of blood flow between the tissues. (vin.com)
  • This causes a slight difference in the concentration of cations and anions between the two fluid compartments. (wikipedia.org)
  • Additions or losses of sodium from the body are mostly to or from the ECF because the actions of cellular Na-K-ATPases prevent major changes in intracellular sodium concentration. (mhmedical.com)
  • This fluid is not static, but is continually being refreshed by the blood capillaries and recollected by lymphatic capillaries. (wikipedia.org)
  • The plasma that filters through the capillaries into the interstitial fluid does not contain red blood cells or platelets as they are too large to pass through but can contain some white blood cells to help the immune system. (wikipedia.org)
  • 3 , 4 The lymphatic capillaries of the superficial system are interconnected and cover the entire surface of the body. (wiley.com)
  • About 28 of the 42 liters of fluid in the body are inside the 100 trillion cells and are collectively called the intracellular fluid. (123doc.org)
  • The highest human sweat rate recorded is 5 liters (169 oz.) per hour measured on a resting body exposed to a hot environment. (active.com)
  • Reduction of fluid intake occurs irrespective of space motion sickness and leads to hypovolemia. (biologists.org)
  • Nevertheless, it is fascinating that elevated ADH levels and reduced fluid intake occur simultaneously early in flight. (biologists.org)
  • Furthermore, excess pre-exercise fluid intake enhances thermoregulatory ability, as well as increasing plasma volume to maintain cardiac output. (springer.com)
  • However, hyperhydrating before exercise is difficult, because a large fluid intake is typically accompanied by diuresis. (springer.com)
  • The body's chief mechanism, by far, for maintaining fluid balance is to adjust its fluid output so that fluid output equals fluid intake. (bway.net)
  • Conversely, the less the fluid intake, the less the urine volume output. (bway.net)
  • How does the total intake of fluids compare with the total output of fluids? (prezi.com)
  • Eating alkaline-forming foods can balance out the intake of excess acids and help flush them from the body. (essense-of-life.com)
  • In particular, DMA can be build in the body during bacterial degradation of choline or lecithin inside the intestinal tract (DMA excretion was directly related to the dose of choline administered), but variations in choline intake that might occur as part of consumption of normal foods are not likely to significantly increase TMA and DMA production, and therefore change our exposure to precursors of nitrosamines only somewhat. (europa.eu)
  • It is also called the " interstitium " (in between), the " extracellular fluid compartment " or the " interstitial fluid compartment "-just to confuse the hell out of us! (homedialysis.org)
  • The study suggests an organ called the interstitium is a series of interconnected, fluid-filled compartments throughout the body. (usatoday.com)
  • Scientists have identified a new organ in the human body, called 'interstitium. (usatoday.com)
  • Scientists using a special live imaging technique called a Probe-based Confocal Laser Endomicroscopy (pCLE) to find the interstitium in various parts of the body including the lungs and digestive tract. (usatoday.com)
  • The study said the interstitium can compress or expand in size, suggesting it could serve as "shock absorbers" for other parts of the body. (usatoday.com)
  • this enables them to absorb fluids and macromolecules from the interstitium. (wiley.com)
  • The remaining fluid is "interstitial," and the current study is the first to define the interstitium as an organ in its own right, and as one of the largest of the body, say the authors. (medicalxpress.com)
  • Though further research is needed to determine if the interstitium should in fact be classified as its own organ, understanding how the interstitial fluid works could be significant in diagnosing and tracking the spread of cancer and other serious diseases. (mesothelioma.com)
  • Because the interstitium can be found throughout the body, the researchers believe understanding it could have impacts on diseases and conditions linked to any health system in the body, especially a better understanding of how metastasis or spreading of these diseases may occur. (mesothelioma.com)
  • It distributes into ALL 3 compartments (through pores and aquaporins) in PROPORTION to the VOLUME of the compartment. (brainscape.com)
