Eco-innovative possibilities for improving the quality of thawed cod fillets using high-power ultrasound

In order to improve the quality of thawed cod fillets and minimize the impact of processing, an extended hydration phase is applied in the fishery product industry in order to recover the water lost during freezing and thawing. Such long phases not only compromise productivity, but increase the chances of microbial growth in fish. Ultrasound (US) is a technology that could reduce these long hydration times, thanks to its capacity to improve mass-transfer processes, thereby limiting the development of fish microbiota. This investigation studies the effect of different US intensities (25 kHz, 29.4 W/kg to 2.9 W/kg, 113.7 to 15.3 W) on weight gain (WG) in the hydration process of cod fillets. The influence of the hydration medium’s pH (from pH 8.5 to 10.5) in combination with US was likewise evaluated. Microbiological and sensory analyses were carried out at the end of the hydration process in order to evaluate its impact. The higher the applied US power, the lower was the WG. US intensities of 2.9 W/kg produced the highest increments in WG (18.6%), reducing hydration time by 33% and thereby achieving the same hydration values as in control samples. The combination of US with a controlled pH of 8.5 permitted to shorten hydration time by an additional day, and also led to improved microbial quality in comparison with control samples. Sensorial analyses indicated that after 5 d of hydration, Quality Index Method (QIM) values were better than those obtained for control samples after 5 and 7 d. Specifically, color and gaping were the sensorial attributes of cod fillets better protected with the application of US.

Chloride ions migration and induced reinforcement corrosion in concrete with cracks: A comparative study of current acceleration and natural marine exposure

The aim of this paper is to investigate the corrosion relationship between reinforced concrete exposed to natural marine environment and applied current acceleration. Chloride ions migration and reinforcement corrosion behaviour in different cracked concrete are studied by two testing methods: 700-day exposure in a marine tidal zone and applied current accelerated corrosion. The mechanism comparison of chloride ion diffusion between two techniques is discussed. The results show that cracks have more influence on reinforced concrete under electrochemical corrosion than that under natural exposure. The corrosion rates of natural and accelerated corrosion were quantitatively compared: the latter is two orders of magnitude faster than the former when the crack width is over 0.20 mm. The different composition and distribution of corrosion products between techniques are demonstrated. (C) 2020 Elsevier Ltd. All rights reserved.

Association of Salt Iodization and Urine Iodine Concentration in Schoolchildren from Public Schools in Northeast of Brazil

Iodine deficiency (ID) is recognized as a leading risk factor for child development. Universal salt iodization (USI) is an effective and well-established intervention strategy for the prevention of iodine deficiency disorders (IDD). To evaluate the levels of iodine in household salt samples and the urinary iodine concentration (UIC) in schoolchildren aged 6 to 14 years in public schools in Bahia, Brazil. A cross-sectional study was conducted with 1231 students (6 to 14 years old) from 17 public schools in Bahia. The iodine concentration was evaluated in salt and UIC samples. The adapted Sandell-Kolthoff reaction was used to determine urinary iodine levels. A spectrophotometer (UV-Vis) was used to examine the reduction of ceric ammonium sulfate. A standard iodine solution using a potassium iodate was used to extrapolate the iodine concentrations. The total of 665 salt samples had a median iodine concentration of 24 mg/kg (25th-75th percentile 17.0 to 28.5 mg/kg). The largest proportion (79.6%) of salt samples had iodine concentration in the recommended range, 17.6% of the samples presented iodine at a salt concentration below the established level (<15 mg/kg) and a small proportion was above it (2.8%). The general mean urinary iodine concentration (MUIC) was 217.53 +/- 28.30 mu g/L and median was 205.50 mu g/L. The students evaluated and the salt samples analyzed showed satisfactory results, as recommended by Brazilian legislation and nutritional recommendations of the World Health Organization (WHO).

Freshwater salinization increases survival of Escherichia coli and risk of bacterial impairment

Elevated levels of Escherichia coli (E. coli) are responsible for more designated freshwater stream impairments than any other contaminant in the United States. E. coli are intentionally used as a sentinel of fecal contamination for freshwaters because previous research indicates that salt concentrations in brackish or marine waters reduce E. coli survival, rendering it a less effective indicator of public health risks. Given increasing evidence of freshwater salinization associated with upland anthropogenic land-use, understanding the effects on fecal indicators is critical; however, changes in E. coli survival along the freshwater salinity range (<= 1500 mu S cm(-1)) have not been previously examined. Through a series of controlled mesocosm experiments, we provide direct evidence that salinization causes E. coli survival rates in freshwater to increase at conductivities as low as 350 mu S cm(-1) and peak at 1500 mu S cm(-1), revealing a subsidy stress response across the freshwater-marine continuum. Furthermore, specific base cations affect E. coli survival differently, with Mg2+ increasing E. coli survival rates relative to other chloride salts. Further investigation of the mechanisms by which freshwater salinization increases susceptibility to or exacerbates bacterial water quality impairments is recommended. Addressing salinization with nuanced approaches that consider salt sources and chemistry could assist in prioritizing and addressing bacterial water quality management. (C) 2021 Elsevier Ltd.

Control of viscosity by addition of calcium chloride and glucono-delta-lactone to heat treated skim milk concentrates produced by reverse osmosis filtration

The viscosity of skim milk concentrates increases during storage as result of interactions between milk proteins, minerals and other solids. The present study demonstrates how these interactions can be controlled by addition of calcium or glucono-delta-lactone. Milk concentrates, produced from reverse osmosis with 28% total solids, were heat-treated at 75 or 110 degrees C for 18 s, followed by addition of CaCl2 (0, 25 or 50 mM) and glucono-delta-lactone (0 or 80 mM), before storage at 5 degrees C for 20 days. Addition of CaCl2, glucono-delta-lactone or their combination were found to reduce the viscosity build-up during storage, but the extension depends on the intensity of heat-treatment and pH of the concentrates. The more pronounced effects were observed for concentrates heat-treated at 110 degrees C, which were also the more viscous concentrates. An increase of colloidal calcium reduce the partial specific volume of casein micelles leading to a less viscous milk matrix. (C) 2020 Elsevier Ltd. All rights reserved.

Pore characteristics of recycled aggregate concrete and its relationship with durability under complex environmental factors

The influences and mechanisms of single and coupled effect of carbonation, dry-wet cycles and freeze-thaw cycles on the durability of three types of recycled aggregate concrete were studied. The compressive strength, chloride ion migration coefficient and micro pore parameters of recycled aggregate concrete were tested. The results showed that carbonation and dry-wet cycles can improve the pore tortuosity and reduce the connectivity of pores, while freeze-thaw cycles, coupling of carbonation and freeze-thaw cycles, and coupling of carbonation, dry-wet cycles and freeze-thaw cycles can significantly reduce the pore tortuosity and deteriorate the pore structure. The key reason for durability failure of recycled aggregate concrete in a complex environment is the increase of large pore volume fraction. When more factors are coupled, the increase in the pore volume fraction is greater. Based on the pore tortuosity and large pore volume fraction, an integrated pore index was proposed, and a prediction model of compressive strength and chloride ion migration coefficient of recycled aggregate concrete under complex environmental factors was established, which provided the basis to evaluate and maintain the durability of recycled aggregate concrete.

Catalytic Activity of Pt Loaded Zeolites for Hydroisomerization of n-Hexane Using Supercritical CO2

The present study investigates the synthesis of novel strontium (Sr) and barium (Ba) modified crystalline zeolites including Zeolite Socony Mobil-5 (ZSM-5) and Mordenite (MOR) utilizing a batchwise ion-exchange method with an appropriate chloride solution of 3 N at pH 7.2 and 50 degrees C. Modified zeolites (Ba-ZSM-5 and Ba-MOR, Sr-ZSM-5 and Sr-MOR) were coated with an inert metal (Pt) by a novel supercritical CO2 method using PtMe2COD as a precursor for n-hexane hydroisomerization in a microreactor unit at different temperatures (250-325 degrees C), H-2/HC ratios of 3, 6, and 9, and a pressure of 5 bar. The acidic and physical features of Pt loaded zeolites were systematically characterized using FT-IR, XRD, BET surface area measurements, TGA, and TEM techniques. It is found that the metal loading in scCO(2) results in more uniform and very small metal nanopartide (1.37 nm) dispersion with high stability after reduction. It is also revealed that high loading pressure in scCO(2) (280-300 bar) results in higher catalytic activity and surface area. The maximum conversion and selectivity of about 80 and 90% were achieved for n-hexane isomerization at 275 degrees C and a H-2/HC ratio of 6 for Pt/Sr-ZSM-5 catalyst. Results reported that Pt loaded over all zeolites (H-MOR, Sr-MOR, Ba-MOR, H-ZSM-5, Ba-ZSM-5, and Sr-ZSM-5) by the scCO(2) method showed the minimum production of cracking products (C-1-C-5) and maximum isomeric products including iso-C-6 isomers (2,2-DMB, 2,3-DMB, 2-MP, and 3-MP). Furthermore, the overall results of the rate of reaction revealed that Pt/Sr-ZSM-5 and Pt/Ba-ZSM-5 catalysts showed a better rate of isomerization (46.44%) and conversion (47%) for n-hexane at 300 degrees C and a H-2/HC ratio of 9 with a minimum rate of cracking. However, it is conduded that the small, pored size Pt loaded ZSM-5 zeolite showed the highest catalytical activity compared to large pored MOR zeolite making it of great interest for diesel and gasoline formation in the oil refining industry.

Graphene oxide grafted gold nanoparticles and silver/silver chloride nanoparticles green-synthesized by a Portulaca oleracea extract: Assessment of catalytic activity

A Portulaca oleracea (or purslane) extract was used as a green reductant for synthesizing both gold nanoparticles and silver/optical chloride nanoparticles without the use of any other external reductants, surfactants, stabilizing agents, or halide ions. Both nanoparticles demonstrated their surface plasmon resonance at 543 nm for the gold nanoparticles and 423 nm for the silver/silver chloride nanoparticles. The X-ray diffraction pattern exhibited a face-centered cubic nanoparticle structure. Mainly spherical-shaped nanoparticles were observed in field emission transmission electron microscopy images with an average size of 11.34 +/- 4.23 nm for the gold nanoparticles and 15.01 +/- 4.49 nm for the silver/silver chloride nanoparticles. Graphene oxide-grafted gold nanoparticles and silver/silver chloride nanoparticles using the P. oleracea extract were synthesized by either in situ or ex situ methods. X-ray photoelectron spectra confirmed that gold and silver/silver chloride nanoparticles were successfully grafted onto the graphene oxide sheet. The catalytic activity of these graphene oxide nano composites was assessed with the 4-nitrophenol reduction reaction. Among the tested nanocomposites, graphene oxide-grafted silver/silver chloride nanoparticles synthesized by the ex situ method exhibited an excellent ca-pacity as a nanoscale catalyst with reasonable recyclability. The straightforward method offers new insight into grafting metallic nanoparticles onto graphene sheets via an entirely green strategy using plant extracts.

Correction of serum chloride concentration in dogs with congestive heart failure

Background Hypochloremia associated with congestive heart failure (CHF) in dogs is likely multifactorial. Loop diuretics cause 1:2 sodium [Na+]:chloride [Cl-] loss, whereas water retention causes a 1:1 [Na+]:[Cl-] dilution. Mathematical [Cl-] correction separates these effects on [Cl-]. Hypothesis We hypothesized that corrected [Cl-] (c[Cl-]) would not differ from measured [Cl-] (m[Cl-]) in dogs with controlled CHF because of loop diuretics, and dogs with refractory CHF would have higher c[Cl-] than m[Cl-], indicating relative water excess. Animals Seventy-one client-owned dogs with acquired heart disease, without CHF (NO-CHF), 76 with Stage C CHF and 24 with Stage D CHF. Methods Clinicopathological data from a previous study were retrospectively analyzed. Corrected [Cl-], m[Cl-], and differences were compared among NO-CHF, Stage C CHF, and Stage D CHF, using the formula: c[Cl-] = (mid-reference range [Na+]/measured [Na+]) x m[Cl-]. Results Corrected [Cl-] and m[Cl-] were lower in Stage D vs Stage C and NO-CHF (all P < .0001). The c[Cl-] was higher than m[Cl-] in Stage D (P < .0001) but not Stage C or NO-CHF. Median difference between c[Cl-] and m[Cl-] was higher for Stage D vs Stage C (P = .0003). No hypochloremic Stage D dogs had normal c[Cl-], but 11/24 had [Cl-] that was increased by >2 mmol/L. Conclusions and Clinical Importance Serum [Cl-] increased after mathematical correction in Stage D CHF dogs but not in Stage C and NO-CHF dogs. Although c[Cl-] was higher than m[Cl-] in Stage D dogs supportive of relative water excess, hypochloremia persisted, consistent with concurrent loop diuretic effects on electrolytes. Future study correlating c[Cl-] to antidiuretic hormone concentrations is warranted.

Exploratory Study on Lercanidipine Hydrochloride Polymorphism: pH-Dependent Solubility Behavior and Simulation of its Impact on Pharmacokinetics

This work describes an exploratory experimental and in silico study of the influence of polymorphism, particle size, and physiology on the pharmacokinetics of lercanidipine hydrochloride (LHC). Equilibrium and kinetic solubility studies were performed on LHC forms I and II, as a function of pH and buffer composition. GastroPlus (R) was used to evaluate the potential effect of solubility differences due to polymorphism, particle size, and physiological conditions, on the drug pharmacokinetics. The results indicated that solubilities of LHC polymorphs are strongly dependent on the composition and pH of the buffer media. The concentration ratio (C-I/C-II) is particularly large for chloride buffer (C-I/C-II = 3.3-3.9) and exhibits a slightly decreasing tendency with the pH increase for all other buffers. Based on solubility alone, a higher bioavailability of form I might be expected. However, exploratory PBPK simulations suggested that (i) under usual fasted (pH 1.3) and fed (pH 4.9) gastric conditions, the two polymorphs have similar bioavailability, regardless of the particle size; (ii) at high gastric pH in the fasted state (e.g., pH 3.0), the bioavailability of form II can be considerably lower than that of form I, unless the particle size is < 20 mu m. This study demonstrates the importance of investigating the effect of the buffer nature when evaluating the solubility of ionizable polymorphic substances. It also showcases the benefits of using PBPK simulations, to assess the risk and pharmacokinetic relevance of different solubility and particle size between crystal forms, for diverse physiological conditions.
