Further studies on the mechanism of adrenaline-induced lipolysis in lipid micelles. (1/993)

Lipase [EC 3.1.1.3] depleted lipid micelles, in which lipolysis was not elicited by adrenaline, were prepared from lipid micelles. When these lipase-depleted lipid micelles incubated with adipose tissue extract containing lipase activity, adrenaline-induced lipolysis was restored to almost the same level as that of native lipid micelles. Adrenaline-induced lipolysis was not restored when the lipase-depleted lipid micelles were homogenized or sonicated. Various tissue extracts from kidney, lung, liver, and pancreas, and post-heparin plasma, which contained lipase activity, restored adrenaline-induced lipolysis in lipase-depleted lipid micelles.  (+info)

Sentinel lymph node biopsy and axillary dissection in breast cancer: results in a large series. (2/993)

BACKGROUND: Axillary lymph node dissection is an established component of the surgical treatment of breast cancer, and is an important procedure in cancer staging; however, it is associated with unpleasant side effects. We have investigated a radioactive tracer-guided procedure that facilitates identification, removal, and pathologic examination of the sentinel lymph node (i.e., the lymph node first receiving lymphatic fluid from the area of the breast containing the tumor) to predict the status of the axilla and to assess the safety of foregoing axillary dissection if the sentinel lymph node shows no involvement. METHODS: We injected 5-10 MBq of 99mTc-labeled colloidal particles of human albumin peritumorally in 376 consecutive patients with breast cancer who were enrolled at the European Institute of Oncology during the period from March 1996 through March 1998. The sentinel lymph node in each case was visualized by lymphoscintigraphy, and its general location was marked on the overlying skin. During breast surgery, the sentinel lymph node was identified for removal by monitoring the acoustic signal from a hand-held gamma ray-detecting probe. Total axillary dissection was then carried out. The pathologic status of the sentinel lymph node was compared with that of the whole axilla. RESULTS: The sentinel lymph node was identified in 371 (98.7%) of the 376 patients and accurately predicted the state of the axilla in 359 (95.5%) of the patients, with 12 false-negative findings (6.7%; 95% confidence interval = 3.5%-11.4%) among a total of 180 patients with positive axillary lymph nodes. CONCLUSIONS: Sentinel lymph node biopsy using a gamma ray-detecting probe allows staging of the axilla with high accuracy in patients with primary breast cancer. A randomized trial is necessary to determine whether axillary dissection may be avoided in those patients with an uninvolved sentinel lymph node.  (+info)

Transport of colloidal particles in lymphatics and vasculature after subcutaneous injection. (3/993)

This study was designed to determine the transport of subcutaneously injected viral-size colloid particles into the lymph and the vascular system in the hind leg of the dog. Transport of two colloid particles, with average size approximately 1 and 0.41 microm, respectively, and with and without leg rotation, was tested. Leg rotation serves to enhance the lymph flow rates. The right femoral vein, lymph vessel, and left femoral artery were cannulated while the animal was under anesthesia, and samples were collected at regular intervals after subcutaneous injection of the particles at the right knee level. The number of particles in the samples were counted under fluorescence microscopy by using a hemocytometer. With and without leg rotation, both particle sets were rapidly taken up into the venous blood and into the lymph fluid. The number of particles carried away from the injection site within the first 5 min was <5% of the injected pool. Particles were also seen in arterial blood samples; this suggests reflow and a prolonged residence time in the blood. These results show that particles the size of viruses are rapidly taken up into the lymphatics and blood vessels after subcutaneous deposition.  (+info)

Perineuronal nets of proteoglycans in the adult mouse brain, with special reference to their reactions to Gomori's ammoniacal silver and Ehrlich's methylene blue. (4/993)

As our previous studies have indicated, many subsets of neurons in the vertebrate brain possess a sulfated proteoglycan surface coat which reacts to cationic iron colloid and aldehyde fuchsin. The present study demonstrated that this surface coat is supravitally stained with Ehrlich's methylene blue, and doubly with this blue and aldehyde fuchsin, a finding suggesting its being identical to Cajal's superficial reticulum (red superficial) and to Golgi's reticular coating (revetement reticulare). The perineuronal surface coat was further stained with Gomori's ammoniacal silver, and doubly with this silver and cationic iron colloid. These neurons with such a proteoglycan surface coat usually expressed cell surface glycoproteins which were labeled with lectin Wisteria floribunda agglutinin. Hyaluronidase digestion did not interfere with this lectin labeling of the glycoproteins, methylene blue and Gomori's ammoniacal silver staining of the surface coat, while it erased the cationic iron colloid and aldehyde fuchsin staining of the surface coat. These findings suggest that the perineuronal proteoglycan surface coat is associated with some additional molecules which are resistant to hyaluronidase digestion and stainable with methylene blue and Gomori's ammoniacal silver. The possibility is suggested that these molecules might represent "ligand proteoglycans" connecting the perineuronal proteoglycans and cell surface glycoproteins.  (+info)

Failure of amphotericin B colloidal dispersion in the treatment of paracoccidioidomycosis. (5/993)

Although amphotericin B desoxycholate is considered the most effective treatment for disseminated Paracoccidioides brasiliensis infections, little is known about the efficacy of lipid-based formulations of amphotericin B in this infection. In this study, we treated four adults with the juvenile form of paracoccidioidomycosis with 3 mg/kg/day of amphotericin B colloidal dispersion for at least 28 days. Although all of the patients initially responded by clinical observation, all four patients relapsed within six months. The use of amphotericin B colloidal dispersion for the initial induction of paracoccidioidomycosis failed to cure this infection. Possible reasons for failure include dose, duration, or reduced efficacy of this lipid preparation. For many fungal infections, lipid-based preparations have been shown to have a therapeutic-toxic advantage, but our experience with Paracoccidioides infections suggests that more careful studies will need to be performed before they can be recommended for use in this mycosis.  (+info)

Osmotic pressure contribution of albumin to colloidal interactions. (6/993)

Two surfaces that come in close contact in a solution with macromolecules present experience an attractive force caused by the osmotic pressure. We present a measurement of this effect by using a micrometer-sized sphere bound to a flat plate through a single molecular attachment in an albumin-containing solution. We obtain the osmotic part of the interaction potential with a resolution of <1 nm and a fraction of kTroom. This attractive interaction is seen to have a range comparable to the size of the albumin molecule. The results are broadly in agreement with a geometric model first proposed by Asakura and Oosawa.  (+info)

The metabolic effects of estriol in female rat liver. (7/993)

The effects of estriol on oxygen uptake, glucose release, lactate and pyruvate production, beta-hydroxybutyrate and acetoacetate production in perfused rat liver as well as, carbon uptake in rat liver and intracellular calcium in isolated Kupffer cells were investigated. Basal oxygen consumption of perfused liver increased significantly in estriol or ethanol-treated rats. But these increased effects were blocked by gadolinium chloride pretreatment. In a metabolic study, pretreatment with estriol resulted in a decrease in glucose production and in glycolysis while an increase in ketogenesis. A more oxidized redox state of the mitochondria was indicated by increased ratios of perfusate [lactate]/[pyruvate] and decreased ratios of perfusate [beta-hydroxybutyrate]/[acetoacetate]. Carbon uptake of Kupffer-cell increased significantly in estriol-treated rats. But these increased uptake were not shown in rats pre-treated by gadolinium chloride blocking phagocytosis. In isolated Kupffer cells from estriol-treated rats, intracellular calcium was more significantly increased after addition of lipopolysaccharide (LPS) than in controls. These findings suggest that the metabolic effects of estriol (two mg per 100 mg body wt) can be summarized to be highly toxic in rat liver, and these findings suggest that oral administration of estrogens may induce hepatic dysfunctions and play a role in the development of liver disease.  (+info)

Phase I and pharmacologic study of 9-aminocamptothecin colloidal dispersion formulation in patients with refractory or relapsed acute leukemia. (8/993)

PURPOSE: Topoisomerase I inhibitors have shown promising anti leukemic activity in acute myelogenous leukemia (AML) and myelodysplastic syndrome. In this phase I study, we investigated the toxicity profile, pharmacokinetics, and activity of a prolonged continuous infusion schedule of the colloidal dispersion formulation of 9-amino-camptothecin (9-AC/CD) in patients with acute leukemia. PATIENTS AND METHODS: Patients with refractory or relapsed AML, acute lymphocytic leukemia (ALL) or chronic myelogenous leukemia in blastic phase (CML-BP) were included in the study. Eligibility criteria were age greater than 15 years, performance status of 2 or better, creatinine < 1.5 mg/dl, and bilirubin < 1.5 mg/dl. 9-AC/CD was given as a continuous intravenous infusion over seven days every three to four weeks. The starting dose was 0.2 mg/m2/d (1.4 mg/m2/course). Courses were given every three to four weeks according to toxicity and anti leukemic efficacy. This phase I study used the classical 3 + 3 design. The dose was escalated by 50% until grade I toxicity was observed, and then by 30% to 35% until the dose limiting toxicity was defined. At the maximal tolerated dose (MTD), 8 to 10 patients were planned to be treated to better define the toxicity and early-activity profiles. RESULTS: Thirty-nine patients (AML thirty-six patients; ALL two patients; CML-BP one patient), median age 56 years, were treated. Severe mucositis was the dose limiting toxicity; it occurred in three of six patients treated at a dose of 1.6 mg/m2/d. The MTD was defined as 1.4 mg/m2/day by the phase I design. Upon expansion of the number of patients, 3 of 10 patients had grade 4 mucositis and 1 of 10 patients had grade 3 diarrhea. Nausea and vomiting were uncommon. No complete or partial remission was observed in 37 evaluable patients. However, 9-AC/CD exhibited antileukemic activity, as reflected by the finding of marrow hypoplasia on day 14 in 46% of the patients. Average steady-state concentration of 9-AC lactone was close to 10 nmol/l, and the of 9-AC lactone area under curve (AUC) was 1409 +/- 705 nmol/l. hr. CONCLUSION: The MTD of 9-AC/CD given as a seven-day continuous infusion was 1.4 mg/m2/d (9.8 mg/m2/course) in patients with acute leukemia. This represents three to fourfold dose escalation compared with the MTD of 9-AC given as shorter continuous infusion (three days) in patients with solid tumors. Future studies will determine the activity of prolonged administration of 9-AC/CD in patients with better prognosis acute leukemia.  (+info)

N2 - We examine the solvent-mediated interaction between two neutral colloidal particles due to preferential adsorption in a near-critical binary mixture. We take into account the renormalization effect due to the critical fluctuations using the recent local functional theory. We calculate the free energy and the force between two colloidal particles as functions of the temperature T, the composition far from the colloidal particles c∞, and the colloid separation ℓ. The interaction is much enhanced when the component favored by the colloid surfaces is poor in the reservoir. For such off-critical compositions, we find a surface of a first-order bridging transition ℓ=ℓcx(T,c∞) in the ...

|p|This paper describes the preparation and characterization of poly(ethyl cyanoacrylate) colloidal particles loaded with the organic fluorophore Rhodamine 6G. We studied the physicochemical properties of the colloidal particles: morphology, size-distribution, ζ-potential, fluorescent properties and photobleaching upon UV-light illumination. The properties of the obtained colloidal particles, as well as the dye loading efficiency, were found to depend on the concentrations of ethyl cyanoacrylate monomer and Rhodamine 6G in the polymerization medium. The fluorophore release from the colloidal particles in aqueous buffer is also studied. |inline-formula||alternatives| [...] |/alternatives||/inline-formula||/p|

This paper studies the interactions of colloidal particles in nonpolar solvents. Even though ionization in nonpolar solvents is not possible because of the high energy cost under environments with low dielectric polarizability, it is possible to charge colloidal particles in nonpolar solvents with the use of certain charge control agents. Generally, the electrostatic interaction between the colloidal particles depends on 1) the surface potential, and 2) the screening length of the solvent. In a polar solvent, the screening length can be easily determined through the concentration and valence of the ionic species and the associated conductivity. However, this is difficult in nonpolar solvents because the ionic species are not very well characterized. In addition, the surface potential is difficult to be determined because it is difficult to measure accurately the electrophoretic mobility of particles, since it is too low. Then there are debates about the validity of using the DLVO theory to ...

A colloidal crystal is an ordered array of colloid particles, analogous to a standard crystal whose repeating subunits are atoms or molecules. A natural example of this phenomenon can be found in the gem opal, where spheres of silica assume a close-packed locally periodic structure under moderate compression. Bulk properties of a colloidal crystal depend on composition, particle size, packing arrangement, and degree of regularity. Applications include photonics, materials processing, and the study of self-assembly and phase transitions. IUPAC definition Assembly of colloid particles with a periodic structure that conforms to symmetries familiar from molecular or atomic crystals. Note: Colloidal crystals may be formed in a liquid medium or during drying of particle suspension. A colloidal crystal is a highly ordered array of particles which can be formed over a long range (to about a centimeter). Arrays such as this appear to be analogous to their atomic or molecular counterparts with proper ...
The effect of the presence of colloids on formation, stability and particle size of n-undecane in water nanoemulsions prepared by the Emulsion Inversion Point (EIP) method using nonionic surfactants (Igepals) was studied. The influence of oil-to-water ratio, the HLB value and concentration of the surfactant on their physico-chemical characteristics was also investigated. The stability of emulsions was assessed from changes in the particle size and the particle size distribution as well as through visual assessment of their appearance. The results obtained show that the anticipated positive effect of the colloids on emulsion stability was not confirmed. Phase separation of these systems usually occurred soon after preparation or during a few days of their storage. The particle size of emulsions prepared in the presence of colloids was mostly bigger in comparison with emulsions where colloids were absent. Nevertheless, nanoemulsions with the particle size smaller than 200 nm were also obtained. ...
The results of the present study indicate that both hydroxyethyl starch formulations evaluated increase COP when used in the treatment of horses with low colloid oncotic pressure due to hypoproteinemia. Colloid supplementation improved COP approximately 20%, regardless of the formulation used. However, colloid treatment did not result in COP values within the equine normal range of 18-22 mmHg [7]. Venous pH was not affected by colloid administration. Therefore, it is presumed that type of colloid carrier fluid, normal saline versus lactate ringers solution, did not impact acid-base parameters in this setting.. Jones, P.A. and colleagues encountered similar results in measured COP after administration of 8-10ml/kg of 6% high molecular weight hydroxyethyl starch in 5 hypoproteinemic adult horses and 6 horses ≤1 year of age [8]. In that study, there was a significant increase in measured COP, a mean of 1.5 mmHg post-infusion (13%), that persisted for 24 hours and returned to baseline values at 48 ...
A quartz-crystal-microbalance with dissipation (QCM-D) can measure molecular mass adsorption as well as register adhesion of colloidal particles.

Sand column experiments were conducted to investigate the efficacy of colloidal particles (microspheres) as hydrological tracers. Two main questions were investigated: 1. What is the relationship between breakthrough volume and column height for latex microspheres in a sand column? 2. Is the fraction of latex microspheres filtered out by sand a function of column length? Small-scale sand column experiments were carried out under both saturated and unsaturated conditions. Carboxylated latex microspheres were used as test-tracers. The pore volume of water that flows out of the column before the microspheres breakthrough was linearly related to column height in all trials. The fraction of latex microspheres filtered out by the sand column was not a function of column height unless the water is salty. In one set of unsaturated experiments using 10 mM of NaCl solution, the fraction of microspheres retained in the sand column was linearly related to column height. As this was a only a proof-of-concept ...

Received: June 9, 2001 - Accepted: September 5, 2001). SUMMARY. In this work metallic colloidal dispersions were obtained by simultaneous cocondensation of nickel atoms with organic solvents at 77 K. The atoms were produced by resistive heating and were reacted with 2-propanol, 2-methoxyethanol, 2-ethoxyethanol and acetone to produce colloids.. The kinetic stability of colloid dispersions was related to the solvation effect of organic molecules, e.g. low stability for ketones and higher stability for 2-propanol colloids. The colloidal particles were characterized by UV-Vis measurements showing an absorption band around 212 nm. The electrophoretic measurements reveal that particles are weakly positively charged.. The transmission electron microscopy studies reveal an average particles size distribution ranging from 4 to 23 nm depending on the solvent. Most of the colloids exhibit a spherical shape with some degree of agglomeration.. Keyword: metal colloids, nanostructures, vapor deposition, ...

TY - JOUR. T1 - Particle sizing for flowing colloidal suspensions using flow-differential dynamic microscopy. AU - Richards, James A. AU - Martinez, Vincent A. AU - Arlt, Jochen. N1 - 9 pages, 8 figures. PY - 2021/3/10. Y1 - 2021/3/10. N2 - Particle size is a key variable in understanding the behaviour of the particulate products that underpin much of our modern lives. Typically obtained from suspensions at rest, measuring the particle size under flowing conditions would enable advances for in-line testing during manufacture and high-throughput testing during development. However, samples are often turbid, multiply scattering light and preventing the direct use of common sizing techniques. Differential dynamic microscopy (DDM) is a powerful technique for analysing video microscopy of such samples, measuring diffusion and hence particle size without the need to resolve individual particles while free of substantial user input. However, when applying DDM to a flowing sample, diffusive dynamics are ...

0141]By using each of lectins, i.e. ConA, RCA120, and WGA as proteins, five 100 μl of PBS-T (0.05%) solutions were prepared in Eppendorf tubes so that the protein is contained therein at 10 μM, 8 μM, 6 μM, 4 μM, and 2 μM concentrations. As the colloid solution of sugar-immobilized gold nanoparticles (hereinafter simply referred to as colloid solution), a colloid solution of maltose-immobilized gold nanoparticles, lactose-immobilized gold nanoparticles, and chitobiose-immobilized gold nanoparticles (absorbance of 0.3 mm at 525 nm) were used. 100 μl of the colloid solution of maltose-immobilized gold nanoparticles was added to the ConA-containing PBS-T (0.05%) solution. 100 μl of the colloid solution of lactose-immobilized gold nanoparticles was added to the RCA120-containing PBS-T (0.05%) solution. 100 μl of the colloid solution of chitobiose-immobilized gold nanoparticles was added to the WGA-containing PBS-T (0.05%) solution. In this manner, the mixture solutions of the colloid ...
BACKGROUND and PURPOSE: We have recently shown high-dose human serum albumin therapy to confer marked histological protection in experimental middle cerebral artery occlusion (MCAo). We have now used diffusion-weighted magnetic resonance imaging (DWI) in conjunction with morphological methods to expand our understanding of this therapeutic approach. METHODS: Physiologically controlled Sprague-Dawley rats received 2-hour MCAo by the modified intraluminal suture method. Treated rats received 25% human serum albumin solution (1% by body weight) immediately after the MCA was reopened. Vehicle-treated rats received saline. Computer-based image averaging was used to analyze DWI data obtained 24 hours after MCAo and light-microscopic histopathology obtained at 3 days. In a matched series, plasma osmolality and colloid oncotic pressure, as well as brain water content, were determined. RESULTS: Albumin therapy, which lowered the hematocrit on average by 37% and raised plasma colloid oncotic pressure by ...

In this study, we have examined a crystallization effect of colloidal dispersion induced by the various elongational flows. Extremely strong electrostatic repulsion makes a crystal structure called colloid crystal. A colloid crystal has hundreds of nano-meters in grating scale and it reflects the visible light due to the Bragg diffraction. It has the potential to become different photonic devices such as an inexpensive photonic device and a planar laser source, but it requires the evolution of the process of making a single-crystal with external stimulus. The methods using flow operation described in this study are expected to the crystallization action of a colloidal dispersion. In the experiment, 2 types of the flow have been examined. The flows have a contraction or an expansion part between two parallel plates separated by 0.1 mm gap and it cause deformations of a contraction or an extension for the colloid. We have evaluated the crystallization effects by a spectroscopic observation of ...
Key questions remain unresolved regarding the advantages and limitations of colloids for fluid resuscitation despite extensive investigation. Elucidation of these questions has been slowed, in part, by uncertainty as to the optimal endpoints that should be monitored in assessing patient response to administered fluid. Colloids and crystalloids do not appear to differ notably in their effects on preload recruitable stroke volume or oxygen delivery. Limited evidence nevertheless suggests that colloids might promote greater oxygen consumption than crystalloids. It remains unclear, in any case, to what extent such physiological parameters might be related to clinically relevant outcomes such as morbidity and mortality. Recent randomized controlled trial results indicate that, at least in certain forms of fluid imbalance, albumin is effective in significantly reducing morbidity and mortality. Much further investigation is needed, however, to determine the effects of colloid administration on ...
A method was developed for the purpose of determining the size and shape of anisometric colloidal particles and flexible macromolecules. The experimental technique used for this determination is the measurement of the change in the intensity of the light scattered by anisometric colloidal particles (or macromolecules) when oriented (or deformed) by a velocity gradient. Improvements in the system will extend the present range of measurements to rigid colloidal particles whose longest dimension is less than 300 mu and to high molecular weight polymers. The apparatus has been successfully tested with suspensions of tobacco mosaic virus and the experimental results have been compared with the theory of Okano and Wada (J. Chem. Phys., 34: 405, 1961) for thin rod-like particles. Preliminary observations made with flexible macromolecules indicate that the effect of deformability of high molecular weight polymers, subjected to a velocity gradient, is quite small under the conditions of this study, as predicted
We show how to implement stick boundary conditions for a spherical colloid in a solvent that is coarse-grained by the method of stochastic rotation dynamics. This allows us to measure colloidal rotational velocity auto-correlation functions by direct computer simulation. We find quantitative agreement with Enskog theory for short times and with hydrodynamic mode-coupling theory for longer times. For aqueous colloidal suspensions, the Enskog contribution to the rotational friction is larger than the hydrodynamic one when the colloidal radius drops below 35 nm.
But why not simply scale everything up a few orders of magnitude, using colloidal crystals (with colloids as the repeating units, rather than atoms)? While the interactions between colloids may not be exactly the same as those between atoms, the authors state that colloid crystals can make a good model for crystals in general, and go on to study dislocations in colloid crystals at multiple length scales. Using a laser scanning confocal microscope to determine the positions of individual colloid particles (Figure 1), along with laser diffraction microscopy to detect dislocation structure and growth (Figure 2), the authors present several new findings, most notable of which is that the continuum model for crystal defects yields good physical approximations, even for crystals too thin to be considered good candidates for the model. ...
We present results from recent crystallization studies on marginal binary suspensions of colloidal particles. As small amounts of the second component are added, crystallization slows, and in some cases may cease altogether. The results support a growth mechanism whereby crystallization occurs in conjunction with a local fractionation process near the crystal-fluid interface, significantly altering the kinetics of crystallite nucleation and growth ...
We report a study of reversible adsorption of DNA-coated colloids on complementary functionalized oil droplets. We show that it is possible to control the surface coverage of oil droplets using colloidal particles by exploiting the fact that, during slow adsorption, compositional arrest takes place well before structural arrest occurs. As a consequence, we can prepare colloid-coated oil droplets with a frozen degree of loading but with fully ergodic colloidal dynamics on the droplets. We illustrate the equilibrium nature of the adsorbed colloidal phase by exploring the quasi-two-dimensional phase behavior of the adsorbed colloids under the influence of depletion interactions and present simulations of a simple model that illustrates the nature of the compositional arrest and the structural ergodicity. ...
A tandem-cartridge system was established for studying colloid formation and physical state distribution of trace polycyclic aromatic hydrocarbons (PAHS) in water. The effectiveness of the method for measuring the trace PAH colloids was demonstrated. With aqueous samples prepared by adding the PAH solutes with a small amount of organic solvent carrier, the potential of colloid formation increased with the hydrophobicity and concentration of the solute, but the incipient concentration for the colloid formation may be far lower than the aqueous solubility of the solute. After formation in water, the colloids showed remarkable stability at room temperature, and the stability was greatly reduced by elevated temperature and the presence of a small amount of inorganic electrolytes. The possible mechanism of destabilization of the colloids was discussed, and the mechanism might be of utility in providing insights into the physical state distribution of the solutes in various water samples. However, ...
Solid films with novel optical properties are produced from colloidal suspensions of cellulose crystallites; the colloidal suspensions are prepared by acid hydrolysis of crystalline cellulose under carefully controlled conditions; the solid materials possess a helicoidal arrangement of the constituent crystallites; by appropriate selection of conditions for preparation and treatment of the colloidal suspensions, solid films are produced that reflect circularly polarized visible light; the wavelength of the reflected light can be controlled to give colours across the visible spectrum from red to violet, and if necessary to infrared and ultraviolet wavelengths. The reflected iridescent colours arise from optical interference effects, and change with the viewing angle; this makes the materials ideally suited for optical authenticating devices, since no printing or photocopying technique can reproduce this effect; furthermore, they are easily distinguishable from other optical interference devices since
Various types of crystalloids (oxalate, uric acid calcium, and cystine) are present in urine, which are kept in solution by the presence of colloids (mucin and sulphuric acid) in urine by the process of absorption. There is imbalance in the crystalloid colloid ratio. i.e. increase in crystalloid and fall in colloid level leading to formation of renal stones (Hadimioglu, Saadawy, Saglam, Ertug, & Dinckan, 2008). Urinary stone are formed when colloid lose the solvent action or adhesive property. In ethylene glycol induced urolithic rats observed that an elevated level of urinary phosphorus are responsible for stone formation. Increased excretion of uric acid has been observed for stone formation. The predominance of uric acid crystals in calcium oxalate proteins are capable of binding to calcium oxalate and modulate its crystallization also play an important role in stone formation. Super saturation of urinary colloids results in precipitation as crystal initiation particle(Aksu, Demirci, & Ince, ...
Introduction: Cold crystalloids have been used for induction of therapeutic hypothermia after cardiac arrest but so far the effectiveness of cold colloids has not been evaluated. This prospective study investigates the cooling effect of rapid intravenous infusion of cold crystalloid compared to colloid in a porcine model of ventricular fibrillation (VF).. Methods: VF was electrically induced in twenty-two anesthetized domestic pigs (33 ± 2 kg). Defibrillation was attempted after 15 min CPR using the AutoPulse (Zoll Medical, USA) and artificial ventilation. After spontaneous circulation was restored, the animals were randomized to receive either 1500 mL of 1°C cold Voluven [6% hydroxyethyl starch 130/0.4 in 0.9% NaCl] within 25 min using a Zoll Power Infuser (group A; n = 9), or 1500 mL of 1°C cold normal saline (group B; n = 9), or no infusion (group C; n = 4). The animals were observed for 90 min following infusion. Cerebral, rectal, intramuscular, pulmonary artery, and subcutaneous fat body ...
The objective of this project is the preparation of novel porous nanocapsules. Spherical colloidal particles, such as melamine formaldehyde (MF), are coated with a mixture of a multilayer of diblock copolymers/micelles and polymer coated Au nanoparticles, via the so-called layer-by-layer approach (LbL). Diblock copolymers of PDMA-PDEA and PDEA-PMAA [where PDMA: poly(2-dimethylamino)ethyl-methacrylate, PDEA: poly(diethylamino)ethyl methacrylate & PMAA: poly methacrylic acid], as well as PDMA coated Au nanoparticles, are used to create polymeric micellar multilayers on MF particles. The core MF is dissolved, whereas parts of the outside layer- the corona - are cross-linked with BIEE and parts of it are etched away. By using the film on the colloidal particle as a mask for selective etching, the production of novel porous hollow shells can be investigated. The morphology is studied experimentally via the use of instrumentation such as AFM, DLS, TEM, SEM, Nanosizer, -potential and UV-VIS. This new type of
Three-dimensional photonic crystals of ellipsoidal colloidal particles are prepared by direct convective self-assembly from suspension with the aid of a magnet. The magnetic field provides the orientational order, which is additionally needed for these colloidal particles with symmetry lower than spherical. The positional order is provided by the convection, just as for spherical colloids ...
Introduction: Sensitive detection of ruptured plaque, the sine qua non of stroke and myocardial infarction, remains an unmet challenge. Previous gadolinium-peptide conjugates lacked clinical efficacy and posed a risk for Nephrogenic Systemic Fibrosis.. Objective: The objective was to develop and characterize the first molecular imaging (MI) agent for fibrin based on copper-based nanocolloids.. Methods: Nanocolloids of copper (Cu) (NanoQ) were synthesized (Dav=217 nm, ζ=−13mV) and characterized for MI of thrombus. MR properties of NanoQ in suspension were defined at 3.0 T at 25C followed by MR imaging of fibrin clots with NanoQ or a control (n=3/group) using fibrin-specific antibodies (NIB5F3). In vivo pharmacokinetics and 24 hour biodistribution, and bioelimination of NanoQ was evaluated in rodents.. Results: The particulate relaxivity of the NanoQ was high, r1=66,000±2200 (s•mmol [NanoQ])−1, while the ionic r1 relaxivitiy (4.3±0.1 (s•mmol [Cu])−1) was similar to Gd-DTPA. The ...

The German Kolloid-Gesellschaft, one of the oldest scientific associations, held its biennial general meeting at TUM. Colloids are mixtures in which insoluble microscopic particles of one substance are suspended throughout another substance. Apart from fundamental research, colloids play an important role in pharmacy as well as in nutrition science and the cosmetics industry. As an example, milk is a complex mixture of different colloids and other substances in water. This years colloid conference had the topic multi-responsive systems - an interdisciplinary research field that gets a lot of attention here in Garching, at the departments for physics and chemistry as well as at the Heinz Maier-Leibnitz Zentrum. The conference and workshop were organized by Christine M. Papadakis (TUM), Peter Müller-Buschbaum (TUM) and Dominik Wöll (RWTH Aachen). Responsive (smart) materials react to an outer stimulus (e.g. a small change of temperature or of the pH value) with a strong change of their ...

A team from the physics department of the Johannes Gutenberg University, Mainz, has investigated nucleation processes and interfacial properties of colloidal crystals. Nucleation is omnipresent in our daily life and describes events as diverse as the formation of rain in clouds, the crystallization of proteins or the growth of nano-particles. The studies undertaken using supercomputers Hazel Hen and Hornet of HLRS Stuttgart contribute towards a more fundamental understanding of these processes and the underlying theoretical foundation.
A depletion force is an effective attractive force that arises between large colloidal particles that are suspended in a dilute solution of depletants, which are smaller solutes that are preferentially excluded from the vicinity of the large particles. One of the earliest reports of depletion forces that lead to particle coagulation is that of Bondy, who observed the separation or creaming of rubber latex upon addition of polymer depletant molecules (sodium alginate) to solution. More generally, depletants can include polymers, micelles, osmolytes, ink, mud, or paint dispersed in a continuous phase. Depletion forces are often regarded as entropic forces, as was first explained by the established Asakura-Oosawa model. In this theory the depletion force arises from an increase in osmotic pressure of the surrounding solution when colloidal particles get close enough such that the excluded cosolutes (depletants) cannot fit in between them. Because the particles were considered as hard-core ...
These studies show for the first time that the synthesis of two distinct phase-separated copolymers within one colloidal particle, i.e., poly(methyl methacrylate) (PMMA)/n-butylacrylate (nBA) and poly (nBA)/pentafluorostyrene (p-PFS) phases, results in unique acorn-shaped morphologies and are capable of coalescence. Spectroscopic and morphological analysis combined with contact angle measurements as well as thermodynamic modeling reveal that in an effort to create stable heterogeneous two-phase particle morphologies it is essential to provide desirable interfacial energetic conditions during polymerization and to utilise monomers that have a similar glass transition temperature (T(g)). Such colloidal particles are stable and are able to self-assemble during coalescence, depending upon the surface energy of a substrate. When a particle monolayer coalesces on a high surface tension substrate, the p-PFS phase expresses itself near the film-air interface, whereas for low surface energy substrates, the p-PFS

It is estimated that there are 5x1030 microorganisms on Earth and that approximately 50% live in unconsolidated sediment on the terrestrial subsurface. Subsurface disturbances caused by the constant search for natural resources and our dependence on groundwater make the abundance and diversity of these organisms a global concern. It is vital to many environmental fields, including bioremediation, water purification, and contaminant transport, that we understand how microorganisms and other colloidal particles attach to and detach from natural sediments and ultimately how they travel through porous media. Sticking efficiency (alpha) is a major component of most particle transport theories. It is defined as the ratio of particles that adhere to a collector surface compared to the total number of particles that collide with that surface. In this study, the Interaction Force Boundary Layer (IFBL) model was used to determine the sticking efficiencies of inorganic colloidal particles and Enterococcus ...
substrate may help our understanding of biological processes involving cell membranes, such as multivalent adhesion. To do this, we observe the three-dimensional motion of colloidal particles using a custom made total internal reflection (TIR) microscope. We measure the position of the particles using scattered light from an evanescent wave. The evanescent wave is the result of total internal reflection of a laser from the coverslip-water interface. Since the intensity of the wave decreases exponentially, the amount of scattered light from the particles is related to their vertical position. We then use a suite of custom made software routines to calculate the mean squared displacement, pair-interaction potential and kinetics of binding. From this data, we hope to characterize how colloidal particles interact via DNA hybridization with a solid substrate, and ultimately understand something about the key physical determinants of avidity and specificity in multivalent binding ...

The myth that colloidal silver can turn your skin a bluish color is absolutely only a myth when taken as prescribed by a doctor. The media created a campaign to frighten viewers from using products containing colloidal silver. The man, Paul Karason, described as the Blue Man was attempting to create colloidal silver at home. What he actually created was not truly Colloidal Silver but a high concentrated ionic silver solution. He mixed salt into the solution and used electrolysis, which created a high concentration of silver chloride. Since he believed that he had made a colloidal silver solution he rubbed it on his skin. The solution caused his skin to turn a bluish color. The use of silver solutions began in the late 1800s. It was used as a topical antiseptic. Although, Colloidal Silver is not readily used today among health professionals, there are many states that still require hospitals to use Silver Nitrate to prevent eye infections in newborns. Colloidal Silver must be taken as ...

Although colloidal silver has been used for medicinal purposes for many centuries, in recent years it has come back into circulation. The traditionally claimed benefits of colloidal silver can now be tested by modern science. Recently the UCLA School of medicine conducted medical tests on colloidal silver.. The laboratory tests conducted by Larry C. Ford, the M.D of the Department of Obstetrics and Gynecology from UCLA School of Medicine brought to light the ability of colloidal silver to kill viral, fungal and bacterial organisms.. The individual conducted extensive laboratory tests based on the standard anti-microbial test for disinfectants. The results showed colloidal silver to have anti-bacterial properties for 105 organisms per ml of streptococcus pyogenes, Neisseria, Gardnerella Vaginalis, Gonorrhea and various other enteric pathogens.. Thus it was discovered that colloidal silver can actually kill over 650 bacteria, fungi, parasites, molds and fungi that have the potential to sprout ...

Others may well have heard about it but have no thought what the term basically signifies and how it works. As it turns out, silver colloids are especially useful mixtures which are widely made use of in laboratories all around the planet. The term colloidal silver was coined in the course of the 1990s to describe a mixture containing silver nanoparticles whose silver content totals more than 50% of the mixture. Even so, exactly where lots of businesses have come unstuck is in labelling their items as colloidal silver, devoid of undergoing the detailed and usually pricey laboratory course of action to decide the exact levels of silver in their items. Several companies have advertised silver colloids, when the actual product on the shelves may well be practically nothing of the sort.. So, how can you inform if a item is a correct colloid or not? There are a handful of telltale indicators which show when the silver content of a remedy is significantly less than half. If the colour of a solution is ...
1. The International Space Station Uses Silver to Purify Water. Hospitals have begun using filters containing silver to kill MRSA and other harmful organisms. Even the World Health Organization uses silver and colloidal silver in water filters to disinfect water in developing countries. [1] The fact is colloidal silver is the least harmful metal to humans and one of the most protective.. 2. Silver Kills Harmful Organisms. This is one reason why colloidal silver is used to disinfect water. Historically, silver was used to preserve milk. Settlers would drop a silver dollar in the milk jug to keep it from spoiling. Babies were fed with silver spoons because those that did were generally perceived to be healthier.. 3. Greeks and Romans Used Silver to Prevent Food Spoilage. Not only that, colloidal silver was used by physicians in the early part of the twentieth century. They stopped using it with the arrival of antibiotics. Thats when pharmaceutical companies got in on medical care, and thats when ...
Emergency Alert: Stop EPA From Further Regulating Colloidal Silver as a Pesticide We have only until January 20th to submit comments to the EPA against the proposal by radical environmental groups that want the EPA to immediately begin regulating nanosilver (read: colloidal silver) as a pesticide -- an action that would completely take colloidal silver off the market at some point in time. Apparently, radical environmental groups and fake consumer advocate groups have joined hands to accellerate the ongoing campaign to have the EPA regulate all ...
Over the past decade thousands of Americans have quietly abandoned the use of prescription antibiotic drugs and have turned instead to the use of safe, natural colloidal silver. In fact, when people discovered they could cure the vast majority of their own infections - quickly, safely and effectively with just a few dollars worth of colloidal silver, word began to spread rapidly among the American public.. The giant pharmaceutical companies quickly realized they would soon be losing tens of millions of dollars annually in sales of their expensive prescription antibiotic drugs if they didnt do something about it. Initially, they demanded that the FDA ban the sale of colloidal silver altogether. But try as they might, the FDA couldnt find sufficient grounds for a ban. After all, colloidal silver has a fully documented 90-year medical history of safety and effectiveness!. Not to be stopped, the big drug firms rapidly switched gears: they began pressuring the FDA to restrict the publics access ...

This work proposes a method for fabricating silica-coated gold (Au) nanoparticles, surface modified with poly(ethylene glycol) (PEG) (Au/SiO2/PEG), with a particle size of 54.8 nm. X-ray imaging of a mouse is performed with the colloid solution. A colloid solution of 17.9 nm Au nanoparticles was prepared by reducing Au ions (III) with sodium citrate in water at 80 °C. The method used for silica-coating the Au nanoparticles was composed of surface-modification of the Au nanoparticles with (3-aminopropyl)-trimethoxysilane (APMS) and a sol-gel process. The sol-gel process was performed in the presence of the surface-modified Au nanoparticles using tetraethylorthosilicate, APMS, water, and sodium hydroxide, in which the formation of silica shells and the introduction of amino groups to the silica-coated particles took place simultaneously (Au/SiO2-NH2). Surface modification of the Au/SiO2-NH2 particles with PEG, or PEGylation of the particle surface, was performed by adding PEG with a functional ...
Source:. PAC, 1972, 31, 577 (Manual of Symbols and Terminology for Physicochemical Quantities and Units, Appendix II: Definitions, Terminology and Symbols in Colloid and Surface Chemistry) on page 606. Colloidal Silver is categorized under Hydrophobic sols (colloids which do not readily form when mixed with water).. By contrast solutions are formed when a solvent (such as water) mixes with a solute (chemical compounds such as mineral salts and disassociates the ionic bounds between the metallic component and the non metallic component or a polar compounds such as sugar) to form a homogeneous, single phase mixture (down to the atomic level).. Technically colloidal silver is a Hydrophobic sol, one that does not mix readily with the dispersant to form a colloid.. Sol is a synonym for colloid, you may already be acquainted with the more commonly used term, aerosol a different form of colloid.. To meet the definition of a colloid, a the two phase mixture must consist of suspended material in a ...
Uranium single particle analysis has been performed by inductively coupled plasma-mass spectrometry (ICP-MS) and the performances are compared with that provided by scanning electron microsopy and single particle counting. The transient signal induced by the flash of ions due to the ionisation of all titanium Colloidal particle in the plasma torch can be detected and measured for selected uranium ion masses (U-238(+), U-235(+) or 254[(UO)-U-238-O-16](+)) by the mass spectrometer. The signals recorded via time scanning are analysed as a function of particle size or fraction of the studied element or isotope in the colloid phase. The frequency of the flashes is directly proportional to the concentration of particles in the colloidal suspension. The feasibility tests were performed on uranium dioxide particles. The study also describes the experimental conditions and the choice of mass to detect uranium colloids in a single particle analysis mode.. ...

These lesions are usually located at the foramen of Monro, are hyperdense on CT scans, and generally demonstrate signal intensity of water on MR images, although this depends on their content. When symptomatic, they frequently present with headaches and nausea due to an obstructive hydrocephalus. The authors describe a case of a giant colloid cyst in a patient presenting with complete left-sided vision loss and progressive memory loss, two very atypical findings in colloid cyst presentation. Imaging findings were also atypical, and this case proved to be a diagnostic dilemma because of its clinical and radiological presentation. Histopathological investigation was of utmost importance in the final diagnosis of a colloid cyst. To the authors knowledge this colloid cyst is larger than any other described in the literature. ...
Colloidal silver is okay to take if a person is battling an STD, parasitic infection or a so-called virus. After using colloidal silver, one must detoxify to prevent an accumulation of silver from accumulating in the tissues of joints since the body cannot rid colloids on its own.

Most colloidal silver items only contain 10% charged silver, but greater brands such as Sovereign Silver includes 98% positively charged silver. Does colloidal silver function? There are a lot of conflicting opinions out there, so its critical to have an understanding of how colloidal silver works. Pseudomonas aeruginosa is a typical bacterium that can lead to illnesses in humans. Research have discovered that up to 12% of silver has been discovered in Pseudomonas aeruginosa. In other words, silver can enter bacterial DNA, and it does so without destroying the hydrogen bonds and it prevents the DNA from unwinding.. Silver attaches to oxygen molecules, and reacts with the sulfhydral (H) groups that surround viruses and bacteria. This is thought to aid block cellular respiration, a life-preserving cellular procedure. Cellular respiration is a series of metabolic processes and reactions in cells which convert energy from nutrients into adenosine triphosphate prior to releasing waste merchandise. ...
Ive been suffering from an ear ache for about 6 months. Ive been to doctors and have been given a different diagnosis by nearly every one. Ive been told it is a hormonal imbalance, TMJ, deep infection, collapsed tubes, sinusitis, etc etc etc. The bottom line is that no one really can get to the bottom of what is bothering my poor ears!. In my frustration, Ive turned to searching for natural remedies. Ive had suggestions ranging from Vitamin C to grapefruit seed extract to sticking a clove a garlic in my ear. But the one suggestion that keeps popping up is Colloidal Silver.. The benefits and risks of taking colloidal silver are difficult to pin down. One side says that it is a miraculous curing agent that has been used for decades. Others say it is a dangerous substance that can cause all manner of problems to your body.. So what is the truth? Ive embarked on a quest to find the answer.. Recommended Reading. Colloidal Silver is a compound that consists of silver particles suspended in ...

Colloidal silver has been reported to kill 650 micro-organisms, many of which are associated with human diseases. This does not automatically mean that taking colloidal silver will cure diseases caused by these germs. Colloidal silver only kills micro-organisms when they are in contact with it for a sufficient period of time. The human body is a complex system which may prevent high enough concentrations of colloidal silver from reaching the affected area. The basic guideline that has been recommended for using colloidal silver is that it usually works if you can get a high enough concentration to the affected area. Some will want to experiment with higher amounts (such as 8 or more ounces at a time) to find out what it takes to accomplish this. Do not use colloidal silver if you are allergic to contact with silver metals, or if you notice any digestive upset after use. The following is a partial list of the more than 650 diseases that colloidal silver has been reputed to be ...
Although colloidal silver is approved by the FDA for use as a nutritional supplement, it is NOT currently approved for medical use. The FDA does not allow the makers of colloidal silver supplements to make claims about the products effectiveness against any medical condition on packaging or in literature about the products. The only adverse medical condition known to be caused by chronic use of colloidal silver is argyria--a darkening of the skin pigmentation which creates a blue or gray coloration in humans using colloidal silver at extremely high concentrations for a long period of time. Other potential toxic effects from using massive doses of colloidal silver can include irritability and excitability. Suspended forms of colloidal silver should not produce build-ups of the product inside the body of cats or other animals, as the ions may only attach themselves to single-celled organisms and are eliminated with the pathogens from the body. More concentrated versions of colloidal silver are ...
The formation of pulmonary oedema depends on the balance between capillary hydrostatic pressure, interstitial tissue pressure, plasma colloid osmotic pressure, endothelial permeability, and lymphatic function. The efficiency of lymphatic drainage of interstitial fluid (which can increase >10-fold) is critical in determining the onset and extent of hydrostatic oedema....
TY - JOUR. T1 - Fine-granular cationic iron colloid - Its preparation, physicochemical characteristics and histochemical use for the detection of ionized anionic groups. AU - Seno, S.. AU - Akita, M.. AU - Ono, T.. AU - Tsujii, T.. PY - 1985/7/1. Y1 - 1985/7/1. N2 - In order to obtain distinct and reliable information concerning the localization of ionized anionic groups in tissues, fine-granular cationic ferric hydroxide colloid solution (Fe-Cac-f) was newly devised. This can be obtained by boiling a mixture of ferric chloride and ammonium cacodylate solutions. the colloid particles of Fe-Cac-f are about 1.0 nm in size, i.e., one-fifth of the size of ferric cacodylate colloid (Fe-Cac; Seno et al. 1983a). As with Fe-Cac, Fe-Cac-f particles in the pH range of 1.6-7.6 carry a positive electric charge, but the latter show a better permeation of tissues. Using the Prussian blue reaction, Fe-Cac-f gives a distinct deep-blue color and can be used for the detection of anionic groups of acid ...
The extrinsic physicochemical properties of nanoparticles (NPs), such as hydrodynamic size, surface charge, surface functional group, and colloidal stabilities, in toxicity testing media are known to have a significant influence on in vitro toxicity assessments. Therefore, interpretation of nanotoxicity test results should be based on reliable characterization of the NPs extrinsic properties in actual toxicity testing media. Here, we present a set of physicochemical characterization results for commercially available ZnO NPs, including core diameter, hydrodynamic diameter, surface charges, and colloidal stabilities, in two in vitro toxicity testing media (Roswell Park Memorial Institute [RPMI] and Dulbeccos modified Eagles medium [DMEM]), as well as simple cell viability assay results for selected ZnO NPs. Four commercially available and manufactured ZnO NPs, with different core sizes, were used in this study, and their surface charge was modified with five different surface - coating ...
The prevention of ischemic injury to preserve both end-organ function and improve neurological recovery by the implementation of therapeutic hypothermia has been well established in the literature. However, not only the means by which body temperature is cooled but also the rate by which target temperature is attained remains an area of continued interest and research. The induction of therapeutic hypothermia to begin the process of body temperature lowering through the infusion of a cold solution intravenously into the body may be one variable that influences not only rapidity of cooling but also subsequent clinical outcome. In a recent issue of Critical Care, Skulec and colleagues compared the induction of therapeutic hypothermia by cold normal saline versus cold colloid solution containing hydroxyethyl starch in a porcine animal model of cardiac arrest, assessing both the rate of temperature change and target temperature achieved, in addition to changes in intracranial pressure.

1. This paper gives measurements of the influence of various electrolytes on the cataphoretic P.D. of particles of collodion coated with gelatin, of particles of casein, and of particles of boiled egg albumin in water at different pH. The influence of the same electrolyte was about the same in all three proteins.. 2. It was found that the salts can be divided into two groups according to their effect on the P.D. at the isoelectric point. The salts of the first group including salts of the type of NaCl, CaCl2, and Na2SO4 affect the P.D. of proteins at the isoelectric point but little; the second group includes salts with a trivalent or tetravalent ion such as LaCl3 or Na4Fe(CN)6. These latter salts produce a high P.D. on the isoelectric particles, LaCl3 making them positively and Na4Fe(CN)6 making them negatively charged. This difference in the action of the two groups of salts agrees with the observations on the effect of the same salts on the anomalous osmosis through collodion membranes coated ...
BACKGROUND: We present the synthesis, characterization and initial structure-function analysis of a new class of bioactive agent that allows the application of techniques from colloid science to biological surfaces. Stable colloidal suspensions can be generated by immobilizing a dense brush of soluble polymer at the colloidal surface, creating a zone protected against the adhesion of approaching particles, a phenomenon termed polymeric steric stabilization. This is often accomplished for aqueous colloidal dispersions using adsorbing block copolymers. We demonstrate that water-soluble block copolymers can be designed to adsorb onto heterogeneous biological surfaces and block cell-cell and cell-surface adhesion, using polymer compositions and architectures that are quite different from surfactants used for stabilizing nonbiological colloidal dispersions. RESULTS: Comb copolymers were synthesized having polycationic backbones (poly-L-lysine, PLL), serving as the anchor for binding to the net ...
Hello Saregamapa, Silver does indeed possess antibacterial properties. It is used today as coatings on bandages, urinary catheters, heart stents and more, to help prevent surface bacterial growth. Silver nitrate drops were used in newborn?s eyes to prevent infection. Taking colloidal silver by mouth is another matter however, and a questionable practice. There is no legitimate or scientific research proving that taking colloidal silver supplements is beneficial. The US and Australian governments warn against falling for such scams. ?Throughout history, people have exploited the germicidal properties of silver. The Greeks and Romans stored water and other drinks in silver vessels that were believed to keep the liquids fresh. During the plagues in Europe, wealthy families ate from silver plates and used silver utensils, in the hope that silver might protect them from the disease that was claiming their neighbors lives. Pioneers traveling across the U.S. placed silver and copper coins in their ...

Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a must. Since that time the SPR series has altered according to the fluctuating degree of
