A straightforward method for measuring the range of apparent density of microplastics.

Density of microplastics has been regarded as the primary property that affect the distribution and bioavailability of microplastics in the water column. For measuring the density of microplastis, we developed a simple and rapid method based on density gradient solutions. In this study, we tested four solvents to make the density gradient solutions, i.e., ethanol (0.8 g/cm), ultrapure water (1.0 g/cm), saturated NaI (1.8 g/cm) and ZnCl (1.8 g/cm). Density of microplastics was measured via observing ...


Interrogating the Osmotic Pressure of Self-Crowded Bovine Serum Albumin Solutions: Implications of Specific Monovalent Anion Effects Relative to the Hofmeister Series.

The free solvent-based (FSB) model and osmotic pressure was used to probe the ion binding and protein hydration for self-crowded bovine serum albumin in 0.15 M NaF, NaCl, NaI and NaSCN solutions. All experiments were conducted with solutions at pH 7.4. The regressed results of the FSB model behavior to the measured osmotic pressure was excellent, albeit, the osmotic pressure data for NaSCN was noisy. The resulting ion binding and hydration were realistic values and the covariance of the two parameters was e...

Use of wet-to-moist cleansing with different irrigation solutions to reduce bacterial bioburden in chronic wounds.

The influence of different irrigation solutions, in conjunction with wet-to-moist cleansing, on the reduction of sessile, non-planktonic bacteria which colonise wounds, has not been investigated. In this study, the antibacterial effect of different irrigation solutions, during a 20-minute wet-to-moist cleansing, has been evaluated in chronic wounds.


Carbonate-radical-anions, and not hydroxyl radicals, are the products of the Fenton reaction in neutral solutions containing bicarbonate.

The Fenton reaction, Fe(HO) + HO → Oxidizing product, is of major importance in biology as the major cause of oxidative stress, and in advanced oxidation processes. It is commonly assumed that ·OH is the product of the Fenton reaction. The results presented herein point out that ·OH is indeed the oxidizing product in acidic solutions for [Fe(HO)] > [HO]; Fe is the active oxidizing product in neutral solutions; in slightly acidic solutions for [HO] > [Fe(HO)] a mixture of ·OH and Fe is formed. However C...

Arginine suppresses opalescence and liquid-liquid phase separation in IgG solutions.

Antibody formulation often necessitates the protein concentration to be increased above 100 mg/ml, because of the large therapeutic doses of antibodies required and the volume limitations of subcutaneous injections. However, high concentrations of antibody lead to opalescent states in solution, resulting in safety and application problems. In this study, we investigated the effect of additives on opalescence in IgG solutions. Arginine (Arg) was observed to most effectively suppress opalescence in IgG solu...

Evasion of No-Hair Theorems and Novel Black-Hole Solutions in Gauss-Bonnet Theories.

We consider a general Einstein-scalar-Gauss-Bonnet theory with a coupling function f(ϕ). We demonstrate that black-hole solutions appear as a generic feature of this theory since a regular horizon and an asymptotically flat solution may be easily constructed under mild assumptions for f(ϕ). We show that the existing no-hair theorems are easily evaded, and a large number of regular black-hole solutions with scalar hair are then presented for a plethora of coupling functions f(ϕ).

Influence of the solvent system on the stability of doxycycline solutions.

Concentrated solutions of doxycycline are often added to drinking water of animals for oral antibiotic therapy. However, stability concerns of doxycycline in solution involve an accurate selection of the solvent system to ensure that the active substance will remain within the acceptance range during the product shelf-life and to avoid sub-therapeutic dosage. Different solvent systems have been evaluated in order to determine their influence on the stability of concentrated doxycycline solutions. The result...

Improvement of enzymological properties of pepsin by chemical modification with chitooligosaccharides.

In order to improve the enzymological properties and to enhance the stability of pepsin (PP, EC 3.4.23.1), chitooligosaccharide (COS) was used to chemically modify enzyme molecules of PP. The results showed that one protein band appeared on the PAGE diagram, indicating that the enzyme samples reached electrophoresis purity after purification. The molecular weights of the enzymes before (PP) and after (COS-PP) modification were 38.68 KD and 49.55 KD, respectively. The K and V of PP were 2.40 mg/mL and ...

Exact Solutions for Nonlinear Development of a Kelvin-Helmholtz Instability for the Counterflow of Superfluid and Normal Components of Helium II.

Relative motion of the normal and superfluid components of helium II results in the quantum Kelvin-Helmholtz instability (KHI) at their common free surface. We found the integrability and exact growing solutions for the nonlinear stage of the development of that instability. Contrary to the usual KHI of the interface between two classical fluids, the dynamics of a helium II free surface allows reduction to the Laplace growth equation, which has an infinite number of exact solutions, including the generic fo...

Organic Salts Suppress Aggregation and Enhance the Hyperpolarizability of a π-Twisted Chromophore.

Twisted intramolecular charge transfer (TICT) chromophores exhibit extraordinary hyperpolarizabilities, β, and are therefore promising for electro-optic technologies. Nevertheless, centrosymmetric aggregate formation severely diminishes β in concentrated solutions or in polymer matrices. Here we report the remarkable effects of organic salts on the linear and nonlinear optical response of a high-β benzimidazolium-based TICT chromophore, B2TMC-2. Addition of Bu4P+Br- to B2TMC-2 solutions in CHCl3 induces ...

Solvent Dependent Light-Induced Structures in Gem-Dichlorocyclopropanated Polybutadiene Solutions.

The formation of permanent structures upon mild red laser illumination in transparent polydiene solutions is examined in the case of gem-dichlorocyclopropanated polybutadiene (gDCC-PB) polymers bearing 15% functional units of the dichlorocyclopropane groups. The response were found to be distinct from the precursor PB. Whereas fiber-like patterns were clearly observed in both precursor and gDCC-PB solutions in cyclohexane, these were absent in the case of gDCC-PB/ chloroform but were present in the precurso...

Long-term Physicochemical Stability of Concentrated Solutions of Noradrenaline Bitartrate in Polypropylene Syringes for Administration in the Intensive Care Unit.

Intensive care units use drug solutions within higher concentrations to avoid fluid overload. The purpose of this study was to evaluate the physicochemical stability of concentrated solutions of noradrenaline bitartrate in polypropylene syringes during 30 days of storage at 5°C ± 3°C. Five 50-mL syringes containing 0.240 mg/mL of noradrenaline bitartrate in 0.9% sodium chloride were prepared and stored at 5°C ± 3°C during 30 days. Immediately after preparation and periodically during the storage, nora...

Toxicity assay of lanthanum and cerium in solutions and soil.

Lanthanum (La) and cerium (Ce) are one of the most abundant rare earth elements (REEs). In spite of quite extensive studying of the effects of these lanthanides on biota, some contradictions remain in the results. Also little is known about the effect of lanthanum and cerium on plant cells and their mitotic cycle, especially in soils. In this study, the effects of La and Ce in solutions and soil samples on root growth, mitotic index (MI) and frequency of aberrant cells (FAC) were assayed using one of the mo...

Anti-Erosive Effect of Solutions Containing Sodium Fluoride, Stannous Chloride, and Selected Film-Forming Polymers.

The aim of this study was to evaluate the anti-erosive effect of solutions containing sodium fluoride (F: 225 ppm F-), stannous chloride (Sn: 800 ppm Sn2+), and some film-forming polymers (Gantrez: Poly [methylvinylether-alt-maleic anhydride]; PGA: propylene glycol alginate; Plasdone: poly[vinylpyrrolidone]; and CMC: carboxymethylcellulose). Solutions were tested in an erosion-remineralization cycling model, using enamel and dentin specimens (n = 10, for each substrate). Distilled water was the negative con...

Pilot-scale formation of whey protein aggregates determine the stability of heat-treated whey protein solutions-Effect of pH and protein concentration.

Denaturation and consequent aggregation in whey protein solutions is critical to product functionality during processing. Solutions of whey protein isolate (WPI) prepared at 1, 4, 8, and 12% (wt/wt) and pH 6.2, 6.7, or 7.2 were subjected to heat treatment (85°C × 30 s) using a pilot-scale heat exchanger. The effects of heat treatment on whey protein denaturation and aggregation were determined by chromatography, particle size, turbidity, and rheological analyses. The influence of pH and WPI concentration ...

Internal transport of CO from the root-zone to plant shoot is pH dependent.

We investigated the fate of carbon dioxide (CO ) absorbed by roots or internally produced by respiration using gas exchange and stable isotopic labelling. CO efflux from detached leaves supplied with bicarbonate/CO solutions was followed over six cycles. CO effluxes were detected when bicarbonate solution at high pH was used, corresponding to 71~85% of the expected efflux. No CO efflux was detected when CO solutions at low pH were used but CO efflux was subsequently detected as soon as bicarbonate solutions...

From classical water-ecosystem theories to nature-based solutions - Contextualizing nature-based solutions for sustainable city.

Growing interest in the concept of nature-based solutions (NBS) raises the question of its applicability as a broadly-understood approach to resource management and spatial planning. Although both the European Commission and United Nations consider the use of NBS as a vehicle to achieve numerous sustainability goals, the concept itself remains under-defined. We analyse the NBS concept against the background of classical water-ecosystem theories. We also review a range of potential contributions by NBS to va...

Enzyme kinetics in crowded solutions from isothermal titration calorimetry.

Isothermal titration calorimetry (ITC) is a universal technique that directly measures the heat absorbed or released in a process. ITC is typically used to determine thermodynamic parameters of association of molecules without the need to label them. However, ITC is still rarely applied to study chemical reactions catalyzed by enzymes. In addition, these few studies of enzyme kinetic measurements that have been performed were in diluted solutions. Yet, to estimate realistic kinetic parameters, we have to ac...

A theory of reactant-stationary kinetics for a mechanism of zymogen activation.

A theoretical analysis is performed on the nonlinear ordinary differential equations that govern the dynamics of a reaction mechanism of zymogen activation. The reaction consists of a primary non-observable zymogen activation reaction that it is coupled to an indicator (observable) reaction. The product of the first reaction is the enzyme of the indicator reaction, and both reactions are governed by the Michaelis-Menten reaction mechanism. Using singular perturbation methods, we derive asymptotic solutions ...
