Protective effect of Feijoa sellowianan fruit on testicular toxicity-induced by cadmium chloride

The purpose of the present study was to investigate the protective potential of Feijoa fruit extract on cadmium chloride (CdCl2)-induced testicular injury and pituitary-gonadal axis. Adult male Wistar rats were randomly divided into four groups: (a) control (normal saline, orally), (b) cadmium chloride (0.1 mg/kg, single dose, intraperitoneally), (c) Feijoa fruit extract (400 mg/kg, orally for 30 consecutive days) and (d) CdCl2 + Feijoa fruit extract. One day after receiving the last medicine, the LH, FSH, prolactin and testosterone concentration were assayed. Also, sperm parameters and tissue structure of the testis were evaluated. Administration of Feijoa fruit extract after CdCl2 injection in rats ameliorated sperm parameters such as sperm count, morphology, motility and sperm viability, increased levels of LH, FSH, prolactin and testosterone and improved testicular histology. According to the results of this study, it was shown that Feijoa can reduce the destructive side effects of CdCl2 on testicular tissue and sex hormones of the pituitary-gonadal pathway.

Insight into the Deep Eutectic Solvent Extraction Mechanism of Flavonoids from Natural Plant

Deep eutectic solvents (DESs) are a new class of green solvents with potential applications for the extraction of target compounds from both liquid and solid samples. However, current research in the field has focused on demonstrating the advantages in extraction efficiency in terms of more extracted material and shortened time, while the mechanism of the increased efficiency has not been systematically studied. Herein, we explored the solvent and solute interaction mechanisms with the use of three extraction methods (heating, microwave-assisted, and mechanochemical extraction) and different types of DESs. Choline chloride (ChCl) was used as the hydrogen-bond acceptor, while hydrogen-bond donors used are malonic acid, methylurea, and glycerin. Flavonoids from Flos Sophorae were extracted. H-1 nuclear magnetic resonance (NMR) spectrometry, ultraviolet-visible (UV-vis) spectrometry, scanning electron microscopy (SEM), and ultrahigh-performance liquid chromatography (UPLC) analyses were performed to investigate the interactions between the flavonoids and the plant cell walls with DESs, and chemical reactions between the DESs and flavonoids. We also systematically evaluated the influence of several key factors on the extraction efficiency, which was consistent with the experimental results. The influence of DES in the sample on qualitative and quantitative UPLC analyses was systematically studied, and conditions were optimized. This study should provide insights into the interactions of specific DESs with various target compounds and help design more efficient extraction methods.

CQDs decorated oxygen vacancy-rich CeO2/BiOCl heterojunctions for promoted visible light photoactivity towards chromium (VI) reduction and rhodamine B degradation

Engineering a heterojunction with high photoactivity and better exciton separation in photocatalyst is a promising target for environmental purification. In this context, we fabricated CQDs decorated double-shell CeO2 hollow spheres(D-CeO2)/BiOCl heterojunction (D-CeO2: CQDs/BiOCl) composite by a simple method and scrutinized it photocatalytic performance toward chromium (VI) reduction and rhodamine B degradation. The resultant D-CeO2: CQDs/BiOCl composite is validated much more active under visible light irradiation with the high rhodamine B degradation rate of 0.12min(-1) which is about 3 and 255 times, meanwhile, chromium (VI) reduction rate of 0.015 min(-1) which is about 6 and 32 times higher than the neat BiOCl and D-CeO2, respectively. The interfacial domain of D-CeO2/BiOCl decorated with CQDs for efficient photoinduced charge carriers transfer and separation are the point to attractive photocatalytic performance which combines the double-shell hollow sphere morphology with highly efficient light harvesting, rich OVs for the charge carriers fast separation and accelerated charge transfer after the CQDs participating.

High-pressure HCl leaching of coal ash to extract Al into a chloride solution with further use as a coagulant for water treatment

In the present paper a novel process of the coal ash treatment was developed and analyzed: a high-pressure autoclave HCl leaching of the coal bottom and fly ash from an Omsk coal-fired power plant. This process was applied to extract aluminum from the coal ash into a chloride solution, which can further be used as a coagulant for water treatment. The Al extraction efficiency in this process can reach over 90% at certain process parameters discussed in the present study. Kinetics of the leaching process were evaluated using different kinetic (e.g. shrinking core) models. A semi-empirical equation was proposed for description of the kinetics of the leaching process as a function of the HCl concentration, solid-to-liquid ratio and temperature. Different mechanisms of the leaching process were also discussed and proposed. Water treatment by the obtained Al-chloride showed good results compared to an industrial coagulant; the treated water parameters were within the limits recommended by the World Health Organization for drinkable water.

Elucidating the Role of Embedded Metal-Organic Frameworks in Water and Ion Transport Properties in Polymer Nanocomposite Membranes

Metal-organic frameworks (MOFs) have been extensively studied as promising nanofillers in developing high-performance polymer nanocomposite membranes (PNMs) for efficient water/ion separation applications. However, given the ambiguous role of embedded MOFs, achieving simultaneous improvement in both water permeability and water/ion selectivity of PNMs remains challenging. Here, we elucidates fundamental water and ion transport properties of MOF/PNMs to better understand the role of embedded MOFs in polymer matrices. We prepared freestanding PNMs consisting of a cross-linked poly(ethylene glycol) (XPEG)-based hydrogel and nanoporous zeolitic imidazole framework-8 (ZIF-8) exhibiting high diffusivity selectivity. The transport studies and material characterizations, especially with Raman mapping analysis showing a homogeneous distribution of permeating water molecules throughout ZIF-8/XPEG PNM, revealed that the incorporated ZIF-8 acts as an additional water-permselective channel inside the polymeric matrix, which leads to an unusual reverse-selective ion transport behavior. Ultimately, 20 wt % of ZIF-8 loading could significantly enhance both water permeability (similar to 240%) and water/NaCl selectivity (similar to 160%) compared to a pure polymer membrane by overcoming the conventional permeability-selectivity trade-off limitation. Our finding provides new insights for developing advanced PNMs for water/ion separation.

Study of cholesterol’s effect on the properties of catanionic vesicular systems: Comparison of light-scattering results with ultrasonic and fluorescence spectroscopy

This work is focused on the study of properties associated with the effect of cholesterol levels on the stability of vesicular systems based on the ion pair amphiphile hexadecyltrimethylammonium-dodecylsulphate (HTMA-DS) at laboratory temperature. The HTMA-DS catanionic system was doped with dioctadecyldimethylammonium chloride in a 9:1 M ratio and cholesterol in the amount of 0, 3, 13, 23, 33, 43, 53, 63, and 73 mol.% was added. In this system, the size distributions were studied using the dynamic light-scattering technique and the zeta potential was determined. These standard techniques were supplemented by ultrasonic and fluorescence spectroscopy techniques. Due to low stability and high opalescence of samples, spectral techniques were used only for the samples with cholesterol content above 23 mol.%. The results from High-Resolution Ultrasonic Spectroscopy and from Fluorescence Spectroscopy are in agreement. They equally point to a change in the amount of hydration water in the membrane, the largest amount of which is present in the samples with 43 and 53 mol.% cholesterol. Using the light-scattering technique, the short-term stability of prepared vesicular systems was also observed over the first 36 days. Obtained results confirmed that the most stable systems are those containing 43 or 53 mol.% of cholesterol.

Effect of the food matrix on the capacity of flavor enhancers in intensifying salty taste

The effect of the flavor enhancers monoammonium glutamate (MAG), monosodium glutamate (MSG), disodium guanylate (GMP), and disodium inosinate (IMP) on intensifying salty taste in food matrices (shoestring potatoes, requeijao cheese, and beef burgers) with a reduction in the amount of sodium chloride (NaCl) present was evaluated. Experiments were conducted using a central composite rotational design with two variables: the concentrations of flavor enhancer and NaCl added in the food matrix. The effect of IMP was not significant (P > 0.05) on the intensity of salty taste in any of the matrices analyzed. GMP presented lower performance compared to MAG and MSG in intensifying the salty taste of the treatments, regardless of the reduction of NaCl. Compared to MSG and GMP, MAG showed greater efficiency in intensifying the salty taste in requeijao cheese and beef burger with a reduction of 25%, 50%, 75%, and 100% of NaCl. MSG presented higher efficiency compared to MAG and GMP when applied in shoestring potatoes for all reductions of NaCl tested (25%, 50%, and 75%). The ability of flavor enhancers to improve the salty taste depends on the effect of the flavor enhancer, the complexity of the food matrix, and the reduction of NaCl in foods. Practical Applications The complexity of the food matrix plays a significant role in the perception of salty taste in sodium-reduced products. In these products, sodium reduction may affect the taste enhancer’s effect of enhancing salty taste. Therefore, this study broadens the knowledge of the effects of flavor enhancers on different foods, as well as the ability to enhance salty taste in food matrices with NaCl reduction. Moreover, it provides information on how to reduce the sodium content in these matrices while maintaining the same perception of salty taste as a conventional matrix.

Influence of surface hydrophobicity/hydrophilicity of biochar on the removal of emerging contaminants

This study investigated the removal of Acetaminophen (ACT) using biochars having different physicochemical characteristics. Biochars subjected to post-pyrolysis heat-treatment at 300 degrees C for different treatment times (0, 3.5, 8 and 24 h) were used. The resulting biochars were characterized using FTIR and X-ray diffraction spectroscopy. Experiments for ACT adsorption with different biochars loads (0.0, 0.05, 1, and 2 g L-1) were performed. Using the best performing material, ACT adsorption was investigated for additional biochar loads (4.0, and 6.0 g L-1) and experiments to test the effect of ionic strength were undertaken for different ions (chloride, carbonate, and nitrate) at three different concentrations (0.0, 1.0, 5.0 mM). The results showed that the changes to the surface of the thermally treated biochars increased the adsorption of ACT. The changes in the amount of oxygen-containing functional groups on the surface of the modified biochars (e.g., C=O from 47.8 a.u. to 152 a.u. in the untreated and thermally treated biochars, respectively), as well as modifications to their crystalline structure are considered to be the reason for the observed improvement. Adsorption isotherms and kinetic models suggest the generation of an adsorbate monolayer and chemisorption as the rate-limiting step. The different anions tested were found to have a significant influence on ACT adsorption, related to their electronegativity and steric effect, as confirmed by the multivariate analysis.

Kinetics of poly(3-methacryloylamido propyl trimethyl ammonium chloride) initiated by different initiators

The poly(3-methacryloylamido propyl trimethyl ammonium chloride) (PMAPTAC) was synthesized by radical polymerization in aqueous solution polymerization using ammonium persulfate (APS) and 2,2 ‘-azobis(2-methylpropionamide) dihydrochloride (V50) as initiator, respectively. The kinetics of polymerization were examined by changing various monomer and initiator concentrations via the dilatometer method at a low conversion level. The results showed that the polymerization rate grew with increasing monomer, initiator concentrations, and temperatures. The activation energies of polymerization were E-aA = 153.09 kJ/mol and E-av = 144.76 kJ/mol. The overall polymerization rate equation for the PMAPTAC were R-p = k[M-A](1.64)[I-A](0.71) and R-p = k[M-V](1.57)[I-V](0.91) at the temperature of 45 degrees C for APS and V50, respectively. Based on the experimental results, the effect on the polymerization rate of different initiators was discussed. The studies supplied the experimental basis of the kinetics for the reaction control of PMAPTAC production.

Co-orchestration of acute kidney injury and non-kidney organ failures in critically ill patients with cirrhosis

Background & Aims Little is known on the course of acute kidney injury (AKI) and its relation to non-kidney organ failures and mortality in critically ill patients with cirrhosis (CICs). Methods We conducted a large prospective, single-centre, observational study in which CICs were followed up daily, during the first 7 days of intensive care, collecting prespecified criteria for AKI, extrarenal extrahepatic organ failures (ERH-OFs) and systemic inflammatory response syndrome (SIRS). Results A total of 291 patients admitted to ICU were enrolled; 231 (79.4%) had at least one ERH-OFs, 168 (58%) had AKI at presentation, and 145 (49.8%) died by 28 days. At day seven relative to baseline, 151 (51.8%) patients had progressive or persistent AKI, while the rest remained free of AKI or had AKI improvement. The 28-day mortality rate was higher among patients with progressive/persistent AKI (74.2% vs 23.5%; P < .001) or maximum stage 3 of AKI in the first week. Two-level mixed logistic regression modelling identified independent baseline risk factors for progressive/persistent AKI, including 3 to 4 SIRS criteria, infections due to multidrug-resistant bacteria (MDR), elevated serum bilirubin, and number of ERH-OFs. Follow-up risk factors included increases in bilirubin and chloride levels, and new development of 2 or 3 ERH-OFs. Conclusions Our results show that among CICs admitted to the ICU, the stage and course of AKI in the first week determines outcomes. Strategies combating MDR infections, multiorgan failure, liver failure and intense systemic inflammation could prevent AKI progression or persistence in CICs. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 85-54-1.
