Evaluation of a new method for the analysis of free catecholamines in plasma using automated sample trace enrichment with dialysis and HPLC. (1/1315)

BACKGROUND: Analysis of urinary free catecholamines was automated recently, but analysis of plasma samples posed special difficulties. The present study was undertaken to evaluate a new method for the automated analysis of plasma catecholamines. METHODS: The procedure is based on an improved sample handling system that includes dialysis and sample clean-up on a strong cation trace-enrichment cartridge. The catecholamines norepinephrine, epinephrine, and dopamine are then separated by reversed-phase ion-pair chromatography and quantified by electrochemical detection. RESULTS: Use of a 740- microL sample is required to give the catecholamine detection limit of 0.05 nmol/L and analytical imprecision (CV) between 1.1% and 9.3%. The assay can be run unattended, although >12 h of analysis time is not recommended without cooling of the autosampler rack. Comparison (n = 68) of the automated cation-exchange clean-up with the well-established manual alumina procedure gave excellent agreement (mean, 3.78 +/- 2.76 and 3.8 +/- 2.89 nmol/L for norepinephrine and 0.99 +/- 1.72 and 1.08 +/- 1.78 nmol/L for epinephrine). Hemodialysis had no clear effect on plasma norepinephrine. Epinephrine concentrations were similar (0.05 < P < 0.1) in chronic renal failure patients (0.24 +/- 0.3 nmol/L; n = 15) and healthy controls (0.5 +/- 0.24 nmol/L; n = 31). Dopamine was not quantified, being usually <0.2 nmol/L. CONCLUSION: The availability of such a fully automated procedure should encourage the more widespread use of plasma catecholamine estimation, e.g., after dialysis, exercise, or trauma/surgery and in the investigation of catecholamine-secreting tumors, particularly in the anuric patient.  (+info)

Inhibition of protein denaturation by fatty acids, bile salts and other natural substances: a new hypothesis for the mechanism of action of fish oil in rheumatic diseases. (2/1315)

Natural hydrophobic substances like bile salts (cholate, deoxycholate, chenodeoxycholate, lithocholate and their conjugates with glycine and taurine), fatty acids (caprylic, capric, lauric, myristic, palmitic, stearic, oleic, linoleic, arachidonic, eicosapentaenoic and docosahexaenoic acid) were much more active (EC50 approximately 10(-4)-10(-5) M) than selected amino acids (EC50 > 10(-2) M) and inorganic salts (EC50 approximately 10(-1) M) in inhibiting heat-induced denaturation of human serum albumin in vitro. Fish oil, rich in n-3-polyunsaturated acids such as eicosapentaenoic acid and docosahexaenoic acid, administered p.o. (1 ml/kg) in the rat, protected ex vivo (after 2 hr) serum against heat-induced denaturation more than bendazac, a known antidenaturant drug. Thus, we speculated that the antidenaturant activity of fish oil may be partly (in addition to the known effect on endogenous eicosanoid composition) responsible for its beneficial effects in rheumatoid arthritis and other rheumatic conditions. In this connection, it is of note that the in vitro antidenaturant activity of fish oil fatty acids was higher than that of known antidenaturant drugs such as bendazac and bindarit and nonsteroidal anti-inflammatory drugs like phenylbutazone and indomethacin which could exert beneficial effects in chronic inflammatory conditions by stabilizing endogenous proteins.  (+info)

Kinetics and mechanism of exchange of apolipoprotein C-III molecules from very low density lipoprotein particles. (3/1315)

Transfer of apolipoprotein (apo) molecules between lipoprotein particles is an important factor in modulating the metabolism of the particles. Although the phenomenon is well established, the kinetics and molecular mechanism of passive apo exchange/transfer have not been defined in detail. In this study, the kinetic parameters governing the movement of radiolabeled apoC molecules from human very low density lipoprotein (VLDL) to high density lipoprotein (HDL3) particles were measured using a manganese phosphate precipitation assay to rapidly separate the two types of lipoprotein particles. In the case of VLDL labeled with human [14C]apoCIII1, a large fraction of the apoCIII1 transfers to HDL3 within 1 minute of mixing the two lipoproteins at either 4 degrees or 37 degrees C. As the diameter of the VLDL donor particles is decreased from 42-59 to 23-25 nm, the size of this rapidly transferring apoCIII1 pool increases from about 50% to 85%. There is also a pool of apoCIII1 existing on the donor VLDL particles that transfers more slowly. This slow transfer follows a monoexponential rate equation; for 35-40 nm donor VLDL particles the pool size is approximately 20% and the t1/2 is approximately 3 h. The flux of apoCIII molecules between VLDL and HDL3 is bidirectional and all of the apoCIII seems to be available for exchange so that equilibrium is attained. It is likely that the two kinetic pools of apoCIII are related to conformational variations of individual apo molecules on the surface of VLDL particles. The rate of slow transfer of apoCIII1 from donor VLDL (35-40 nm) to acceptor HDL3 is unaffected by an increase in the acceptor to donor ratio, indicating that the transfer is not dependent on collisions between donor and acceptor particles. Consistent with this, apoCIII1 molecules can transfer from donor VLDL to acceptor HDL3 particles across a 50 kDa molecular mass cutoff semipermeable membrane separating the lipoprotein particles. These results indicate that apoC molecules transfer between VLDL and HDL3 particles by an aqueous diffusion mechanism.  (+info)

Isolation and characterization of a Ca2+ -binding polysaccharide associated with coccoliths of Emiliania huxleyi (Lohmann) Kamptner. (4/1315)

C-occolithophoridae, a group of mostly unicellular algae, possess a cell wall containing calcified plates, called coccoliths. The coccoliths from the species Emilania huxleyi (Lohmann) Kamptner contain a water-soluble acid polysaccharide. In this paper we describe the isolation and some characteristic properties of the polysaccharide, in particular its Ca2+ -binding capacity. A large-scale cultivation of the Coccolithophoridae was worked out and a new procedure for isolating coccoliths was developed. The polysaccharide obtained from the coccoliths contained two types of monobasic acid groups in a total amount of 1.8 mumol/mg polysaccharide. One type consisted of weakly acid groups which were identified as uronic acids. The nature of the stronger acid groups remains to be established. The ratio between the respective groups was 1:0.8. Studies with 45Ca2+ demonstrated that the isolated polysaccharide is capable of binding Ca2+. Equilibrium dialysis revealed that the maximum amount of Ca2+ which can be bound in 0.92 +/- 0.05 mumol/mg polysaccharide. Flow-rate dialysis experiments strongly suggested the presence of two classes of Ca2+ -binding sites differing in affinity for Ca2+. High-affinity sites (dissociation constant Kd for Ca2+ :2.2 +/- 1.0 X 10(-5) M) were found to be present in amounts (0.38 +/- 0.04 mumol/mg polysaccharide) approximately equivalent to the strongly acid monovalent groups mentioned above (0.8 mumol/mg polysaccharide). Low-affinity sites (Kd for Ca2+: -11 +/- 39 X 10(-5) M) were estimated at 0.74 +/- 0.11 mumol/mg polysaccharide. Although this figure could be determined less accurately, it is suggested that the uronic acids (1.0 mumol/mg polysaccharide) are identical to the low-affinity sites. Preferential binding of Ca2+ occurred in a 100-fold excess of Na+ and Mg2+ as was shown by gel filtration. A 100-fold excess of Sr2+ inhibited Ca2+ binding to a great extent while no Ca2+ was bound in the presence of an equimolar amount of La3+. The dissociation constants of the high-affinity sites for Na+, Mg2+, Sr2+ and La3+ (in the presence of Ca2+) were determined with the flow-rate dialysis technique. They confirm the order of binding preference found with gel filtration. A polysaccharide with similar properties could be isolated from subfossil coccoliths of E. hyxleyi (about 1000 years old). The possible role of the polysaccharide as a heterogeneous matrix in coccolith formation is discussed.  (+info)

Polyamine-dependent deoxyribonuclease activity from rat-liver nuclei. (5/1315)

When nuclei isolated from rat liver in a low salt buffer were washed with 0.1 M NaCl solution, the supernatant showed a deoxyribonuclease (DNase) activity. The activity required Mg2+ and in addition spermine or spermidine, and its optimal pH was 7.2-7.4. The activity was higher on denatured (single stranded) DNA than on double-helical DNA. With both substrates the activity was highest at a polyamine concentration at which the DNA-polyamine complex began to precipitate. No Mg2++Ca2+ dependent DNase activity was detected in the preparation.  (+info)

Tissue distribution and characteristics of xanthine oxidase and allopurinol oxidizing enzyme. (6/1315)

Tissue distribution and levels of allopurinol oxidizing enzyme and xanthine oxidase with hypoxanthine as a substrate were compared with supernatant fractions from various tissues of mice and from liver of mice, rats, guinea pigs and rabbits. The allopurinol oxidizing enzyme activities in liver were quite different among the species and the sex difference of the enzyme activity only in mouse liver. In mice, the highest activity of allopurinol oxidizing enzyme was found in the liver with a trace value in lung, but the enzyme activity was not detected in brain, small intestine and kidney, while the highest activity of xanthine oxidase was detected in small intestine, lung, liver and kidney in that sequence. The allopurinol oxidizing enzyme activity in mouse liver supernatant fraction did not change after storage at -20 degrees C or dialysis against 0.1 M Tris-HCl containing 1.15% KCl, but the activity markedly decreased after dialysis against 0.1 M Tris-HCl. On the contrary, the xanthine oxidase was activated 2 to 3 times the usual activity after storage at -20 degrees C or dialysis of the enzyme preparation. These results indicated that allopurinol was hydroxylated to oxipurinol mainly by the enzyme which is not identical to xanthine oxidase in vivo. A possible role of aldehyde oxidase involved in the allopurinol oxidation in liver supernatant fraction was dicussed.  (+info)

Early requirement for alpha-SNAP and NSF in the secretory cascade in chromaffin cells. (7/1315)

NSF and alpha-SNAP have been shown to be required for SNARE complex disassembly and exocytosis. However, the exact requirement for NSF and alpha-SNAP in vesicular traffic through the secretory pathway remains controversial. We performed a study on the kinetics of exocytosis from bovine chromaffin cells using high time resolution capacitance measurement and electrochemical amperometry, combined with flash photolysis of caged Ca2+ as a fast stimulus. alpha-SNAP, a C-terminal mutant of alpha-SNAP, and NEM were assayed for their effects on secretion kinetics. Two kinetically distinct components of catecholamine release can be observed upon fast step-like elevation of [Ca2+]i. One is the exocytotic burst, thought to represent the readily releasable pool of vesicles. Following the exocytotic burst, secretion proceeds slowly at maintained high [Ca2+]i, which may represent vesicle maturation/recruitment, i.e. some priming steps after docking. alpha-SNAP increased the amplitude of both the exocytotic burst and the slow component but did not change their kinetics, which we examined with millisecond time resolution. In addition, NEM only partially inhibited the slow component without altering the exocytotic burst, fusion kinetics and the rate of endocytosis. These results suggest a role for alpha-SNAP/NSF in priming granules for release at an early step, but not modifying the fusion of readily releasable granules.  (+info)

Daunomycin-induced unfolding and aggregation of chromatin. (8/1315)

Using equilibrium dialysis and sedimentation velocity analysis, we have characterized the binding of the anti-tumor drug daunomycin to chicken erythrocyte chromatin before and after depletion of linker histones and to its constitutive DNA under several ionic strengths (5, 25, and 75 mM NaCl). The equilibrium dialysis experiments reveal that the drug binds cooperatively to both the chromatin fractions and to the DNA counterpart within the range of ionic strength used in this study. A significant decrease in the binding affinity was observed at 75 mM NaCl. At any given salt concentration, daunomycin exhibits higher binding affinity for DNA than for linker histone-depleted chromatin or chromatin (in decreasing order). Binding of daunomycin to DNA does not significantly affect the sedimentation coefficient of the molecule. This is in contrast to binding to chromatin and to its linker histone-depleted counterpart. In these instances, preferential binding of the drug to the linker DNA regions induces an unfolding of the chromatin fiber that is followed by aggregation, presumably because of histone-DNA interfiber interactions.  (+info)

Comparison of the Effects of Dialysis Methods (Haemodialysis Peritoneal Dialysis) on Diastolic Left Ventricular Function Dialysis Methods and Diastolic Function
Abstract: Photosystem II (PSII), which produces oxygen using light energy, requires Cl- as a cofactor. Cl- appears to be difficult to remove from PSII because there always remains residual activity of 25-40%. We have tested variations of the dialysis method to deplete PSII of Cl- by introducing NO3- or Br- before dialysis. NO3 pretreatment produced a preparation with suppressed activation by NO3-, suggesting that NO3- replaced Cl- at its site of activation. Br- pretreatment produced the preparation with the lowest residual activity and the highest total activity, indicating that it was the best method for Cl- depletion. The electron paramagnetic resonance (EPR) multiline signal from the S2 state was examined in the presence of Cl-, Br- and NO3- in the Cl- depleted PSII pretreated with NO3-. The signal height followed the same trend as oxygen evolution activity with Cl- > Br- > no anion > NO3.--Abstract from author supplied metadata..

AU - Pan, C.. AU - Shapiro, L. E.. PY - 1988. Y1 - 1988. N2 - Considerable controversy exists concerning the assessment of thyroidal state in critically ill patients with decreased serum T4 and T3 concentrations, in part because serum free T4 values are often low in such patients no matter what method of measurement is used. We developed an ultrafiltration method to measure free T4 and free T3 in undiluted serum and compared the results with those obtained using a standard equilibrium dialysis method to measure free T4 and T3. In 30 consecutive intensive care unit (ICU) patients, serum free T4 values were similar to or higher than those in 12 normal subjects by both methods in most patients and were clearly distinguishable from those in hypothyroid patients. The serum total T4 concentrations in these patients ...
It should be emphasized that the array of structures listed in Table 1 are but a point of departure. The competition dialysis method is completely general, and arrays of structures of particular interest can be designed as desired. The only limitations are that the structures be large enough to be retained by the dialysis tubing chosen for use, and that they are verified to be stable under the ionic conditions of the experiment. Essential quality control experiments to characterize nucleic acid samples were described in detail [41, 42] and include UV absorbance and circular dichroism spectroscopy, and thermal denaturation studies. Fig. 1 Schematic of the competition dialysis experiment. A schematic representation of the structures used is shown on the left.

Plasmid-lipid particles which are useful for transfection of cells in vitro or in vivo are described. The particles can be formed using either detergent dialysis methods or methods which utilize organic solvents. The particles are typically 65-85 nm, fully encapsulate the plasmid and are serum-stable.
abstractNote = {In vivo studies in mice injected intravenously with /sup 125/I-triiodothyronine (T-3) showed a linear relationship between the uptake of the labelled hormone by the tissue and the lipid phosphorous content of the same tissue. However, studies with /sup 125/I-thyroxine failed to show a similar relationship between the lipid phosphorous content of the organ and the uptake of radioactive hormone by the same organ. In vitro studies using equilibrium dialysis technique with isolated lipid extracts of various organs and radioactive thyroid hormones (T-3 and T-4) did not show any relation between the lipid P and the uptake of labelled hormone. On the basis of the observed discrepancy between in vivo and in vitro studies, it is postulated that an organized lipoprotein structure at the cell membrane may be responsible for the entry of the thyroid hormones ...

Abstract:This paper presents a systematic techno-economical analysis and an environmental impact evaluation of a reverse osmosis (RO) concentrate treatment process using electrodialysis (ED) in view of environmental management of brine discharges. The concentrate originates from a secondary effluent treated by RO. Without any treatment, the concentrate would have to be discharged; this is compared in this study to the costs and benefits of an effective treatment method in a pilot scale ED plant. A technical analysis was done both on lab scale and pilot scale for the determination of operational and maintenance costs for the ED installation at the required conditions of process performance and safety. Subsequently, an economical analysis was done to calculate the cost of the different parts of the ED system. It was shown that an operational cost of 0.19 EUR m−3 can be achieved, assuming that the ED concentrate is to decarbonated at pH 6.0 to prevent membrane scaling. Finally, environmental ...

Cardiovascular disease is the number one killer of patients with chronic kidney disease (CKD), and insulin resistance - a lowered level of response to insulin circulating in the blood - is an important cardiovascular risk factor in these patients. Its not clear why patients with CKD often develop insulin resistance, but the retention of compounds that are normally removed from the blood and excreted in the urine may play a role. One such compound is p-cresyl sulfate (PCS), a toxin that is produced by gut bacteria. PCS is retained in CKD patients, and it is poorly removed by most dialysis techniques.. Read more. ...

PURPOSE: To minimize the consumptions of condensed dialysis solution, make-up water and energy and to reduce a cost of dialytic treatment without lowering the dialytic quality, by installing a control unit to feed the signals directed from the blood flow volume into the input side of the unit, from whose output side the signals as functions of blood flow volume are sent out into the system to adjust the flow of dialytic solution. CONSTITUTION: An automatically-operated type control circuit is included in the control unit 100. A signal led from a blood flow rate is sent into the input port of this control unit. The signal is, therefore, led from a feeding flow volume set for a blood pump 30, that is, led from a revolution velocity (RPM) of the blood pump 30, for instance. The flow volume of dialytic solution is automatically adjusted, based on the output signals of the control unit. For this purpose, the output of control circuit 100 is connected either to the dialytic solution pump 20 or

Currently, numerous studies are focused on the valorisation of seawater desalination reverse osmosis brines. Electrodialysis can be used to concentrate one of the primary components (NaCI) and obtain a suitable raw material for industrial applications, such as the chlor-alkali industry. An electrodialysis pilot plant was used to evaluate the efficiency of concentrating a seawater reverse osmosis (SWRO) brine under representative full-scale operational conditions covering the temperature range of a semiarid climate. The results indicate that electrodialysis is a technology that can concentrate SVVRO brines from approximately 70 to 245 g/L NaCl, achieving an additional intrinsic purification of major multivalent ions (Ca2+, Mg2+, SO42-) due to the selectivity patterns of ion exchange membranes and the ion-complexation reactions in the concentrated brines. However, minor components, such as Ni and Cu, are concentrated due to the formation of Cu and Ni complexes with chloride ions to form ...

AU - Metz, S.J.. AU - Nymeijer, K.. AU - Buisman, C.J.N.. PY - 2007. Y1 - 2007. N2 - A huge potential to obtain clean energy exists from mixing water streams with different salt concentrations. Two membrane-based energy conversion techniques are evaluated: pressure-retarded osmosis and reverse electrodialysis. From the literature, a comparison is not possible since the reported performances are not comparable. A method was developed which allows for a comparison of both techniques at equal conditions, with respect to power density and energy recovery. Based on the results from the model calculations, each technique has its own field of application. Pressure-retarded osmosis seems to be more attractive for power generation using concentrated saline brines because of the higher power density combined with ...
Polymeric micelles self-assembled from cholesterol-conjugated poly(ethylene glycol) (PEG) and anchored with transcriptional activator TAT peptide (TAT-PEG-b-Col) were fabricated for delivery of antibiotics across the blood-brain barrier (BBB). Ciprofloxacin, which demonstrated a high bactericidal effect, was efficiently loaded into the micelles by a membrane dialysis method. The ciprofloxacin-loaded micelles were characterized via dynamic light scattering and SEM. The micelles were spherical in nature, having an average diameter of smaller than 180 nm. Sustained release of ciprofloxacin was achieved over 6 h in phosphate-buffered saline (pH 7.4) at 37°C. Confocal laser scanning microscopy reveals that the uptake of Fluorescein 5-isothiocyanate (FITC)-loaded TAT-PEG-b-Col micelles by human astrocytes was much higher than that of free FITC. Animal studies proved that these micelles crossed the BBB and entered the brain. The TAT-conjugated micelles may be used to deliver antibiotics across the BBB ...
Nanotechnology has provided the possibility of delivering drugs to specific cells using nanoparticles.[9] The overall drug consumption and side-effects may be lowered significantly by depositing the active agent in the morbid region only and in no higher dose than needed. Targeted drug delivery is intended to reduce the side effects of drugs with concomitant decreases in consumption and treatment expenses. Drug delivery focuses on maximizing bioavailability both at specific places in the body and over a period of time. This can potentially be achieved by molecular targeting by nanoengineered devices.[10][11] A benefit of using nanoscale for medical technologies is that smaller devices are less invasive and can possibly be implanted inside the body, plus biochemical reaction times are much shorter. These devices are faster and more sensitive than typical drug delivery.[12] The efficacy of drug delivery through nanomedicine is largely based upon: a) efficient encapsulation of the drugs, b) ...
Power production from microbial reverse electrodialysis cell (MRC) electrodes is substantially improved compared to microbial fuel cells (MFCs) by using ammonium bicarbonate (AmB) solutions in multiple RED cell pair stacks and the cathode chamber. Reducing the number of RED membranes pairs while maintaining enhanced electrode performance could help to reduce capital costs. We show here that using only a single RED cell pair (CP), created by operating the cathode in concentrated AmB, dramatically increased power production normalized to cathode area from both acetate (Acetate: from 0.9 to 3.1 W/m 2-cat) and wastewater (WW: 0.3 to 1.7 W/m2), by reducing solution and charge transfer resistances at the cathode. A second RED cell pair increased RED stack potential and reduced anode charge transfer resistance, further increasing power production (Acetate: 4.2 W/m2; WW: 1.9 W/m2). By maintaining near optimal electrode power production with fewer membranes, power densities normalized to total membrane ...
Hemoglobin or hemolysate is used as an indicator for leakage detection in the dialysis membrane interface separating the sterile from the nonsterile circuitry in a recirculating peritoneal dialysis system. The indicator is dissolved in the steril dialysis fluid and is retained within the sterile circuit unless leakage occurs in the membrane. Upon rupture or other leakage in the membrane, fluid turbulance and pressure gradient cause crossflow between the sterile and nonsterile circuitry, endangering the patient with infection, peritonitis and endotoxin shock. Such crossflow is detected by the concurrent coloration caused by the mixing of hemoglobin indicator in the nosterile dialysis fluid.
Treatment of oil and gas (O&G) wastewater is a growing practice that increases water resources available for beneficial reuse. Electrodialysis (ED) is an established desalination process with the potential to remove ions from saline produced water (PW), a byproduct of O&G production. However, the current ED literature lacks studies that investigate the fate of organic contaminants during ED treatment using real PW. This work examines ion exchange membrane (IEM) fouling, system performance, and the transport of organic constituents through IEMs during ED treatment of real PW. A bench-scale ED ...
Erythrocytes, Red Blood Cells (RBCs), have been utilized as biocompatible bioreactors and drug delivery vehicles. RBCs are also used as biological carriers for drugs, enzymes, and peptides. Hypo-osmotic dialysis technique is the most commonly employed to achieve drug encapsulation in RBCs with an appropriate yield. However, the use of RBCs as carriers for fluorescence labeled sensors has not been exploited. We have been investigating the feasibility of utilizing RBCs as optical carriers for biosensors. The first step is to ensure proper encapsulation and signal capture of the fluorescent probes. Streptavidin labeled with Alexa Fluor 750 (SA-AF 750) was utilized as the probe which was then loaded into the RBCs via the hypo-osmotic dialysis technique. The loaded cells were then scanned by using a spectrometer. The excitation scan was set at 750nm. The results showed a peak signal at 775 nm which was an indication of presence of AF 750 in the RBCs. This model could be used in future work to design in vivo

Using One-Way ANOVA test and linear regression methods, the TAFO defined hydration status, but not the FO/ECW, kept a significant relationship with LAVI (p=0.03). When including age, sex, ethiology, dialysis vintage, comorbidities, dialysis technique, hypertension, biochemical parameters (Hemoglobin, Na, K, Albumin, Creatinin), and all echocardiographic measurements including valvular regurgitation and left ventricle mass index, the only confounding factors identified were lean and fat mass percentages related to total weight, and diastolic function measured by transmitral velocities ratio, but the adjusted relationship kept significant (p=0.036).. Plasma sodium was not different between the 37 patients with (136.6mEq/l; CI 95% 135.8-137.4) and 35 patients without (137.3mEq/l; IC95% 136.1-138.6) atrial dilatation (p=0.314).. Left ventricle hypertrophy was present in 73.7% of patients and concentric remodeling in 7.9%. Concentric hypertrophy was present in 63.2% of patients and eccentric ...

When you experience total renal (kidney) failure, your kidneys can no longer perform their usual task of filtering waste from your bloodstream. Dialysis artificially replaces your kidneys by hooking you up to a mechanism that performs kidney functions for you. A dialysis system helps to control blood pressure; removes waste, salt and extra water from your body; and maintains a safe level of bloodstream chemicals like sodium, potassium and bicarbonate. Dialysis can be performed in a hospital, in a separate dialysis unit, or at home with the proper equipment.
A blood purification system comprised of a dialysis system for purifying a patients blood and a dual-lumen catheter coupled to the dialysis system. The dual-lumen catheter is comprised of an elongated cylindrical tube having an internal diametral septum extending along the length thereof. The septum and the walls of the elongated cylindrical tube form at least three longitudinal lumens, the first and second of which have substantially semi-circular transverse cross-sections occupying the major portion of the transverse cross section of the interior of the tube, and the third lumen has a small transverse cross-section located at the intersection of one diametral end of the septum with the tube, between a pair of adjacent corners of the first and second lumens.
A medical fluid machine includes: an enclosure; at least one medical fluid delivery component located inside the enclosure, the component capable of being powered by an external power source or a back-up battery; a transistor in electrical communication with the battery; and a regulator configured to: (i) receive as feedback a supply voltage; and (ii) vary a gate voltage at the transistor to maintain the supply voltage at least substantially at a desired level.
DNA may stick to dialysis tubing after current flow. Either reverse the electrodes and run for 15 seconds to dislodge the DNA or be careful to resuspend the DNA before removing the buffer. To resuspend DNA inside the tubing, first open one clip and carefully remove the agarose slice (which can be restained to verify elution) without losing any buffer. Then replace the clip and with your fingers, press along the length of tubing to mix the DNA with the buffer. Open the clip and remove the buffer with a pipetman. If low yields are suspected, add another 100 l 1 X buffer to the empty tubing and repeat these steps to rinse out the tubing. Final volume should be less than 600 l. If the agarose slice is much longer than 4 cm, the amount of buffer retrieved may be much more than 600 l. In this case split the DNA buffer into two or three tubes so that no tube has more than 600 l ...
