Electrochemical performance and enhanced nitrate removal of homogeneous polysulfone-based anion exchange membrane applied in membrane capacitive deionization cell

This paper aims to investigate different strategies toward the enhancement of nitrate removal in a membrane capacitive deionization cell using different membrane functionalizing agents such as trimethylamine, triethylamine, and N,N,N’,N’-tetramethyl-1,6-hexanediamine as well as a double-layer, novel homogeneous polysulfone-based anion exchange membrane. The prepared membranes exhibited nitrate versus chloride transport number ratio in the range of 0.96-1.52. The salt adsorption capacity for the NaNO3 feed was about 1.4-fold compared to that of using NaCl in case of triethylamine functionalized membrane under individual feeding solutions of 30 mL NaCl or NaNO3 during 30 min, and adsorption/desorption voltages of 1.6/0.0 V process conditions. At the same time, this parameter was about 1.2-fold weaker for the cell with a double-layer membrane. Based on the experiments, it can be inferred that the affinity toward nitrate could be promoted as the chain length of the alkyl group increases (i.e., increasing hydrophobicity of the groups). However, due to decrement in water uptake, the overall electrochemical performance of the membranes tended to weaken as the affinity toward nitrate increased. Results showed that the prepared membranes are suitable substitutions to conventional polystyrene-based ones utilized in membrane capacitive deionization cells.

Disulfiram-copper activates chloride currents and induces apoptosis with tyrosine kinase in prostate cancer cells

Aim: To elucidates the mechanism that disulfiram/copper complex (DSF/Cu) treatment activates chloride channels and induces apoptosis in prostate cancer cells. Methods: Cellular membrane currents were measured by membrane clamp technique; western blot to detect protein expression; flow cytometry to detect apoptosis; immunofluorescence to detect target protein co-localization, and further validated by a combination of protein-protein interaction and mock protein molecular docking techniques. Results: DSF/Cu activated chloride channels and induced apoptosis in LNCaP (a type of androgen-dependent prostate cancer cells) cells. The chloride currents activated by DSF/Cu were significantly reduced after knockdown of CLC3 with siRNA. In addition, DSF/Cu-activated chloride currents were reduced to background current levels after perfusion with genistein, a highly specific tyrosine kinase inhibitor. Conversely, DSF/Cu failed to activate chloride currents in LNCaP cells after 30 minutes of pre-incubation with genistein. When genistein was removed, and DSF/Cu was added, the activated currents were small and unstable, and gradually decreased. Immunofluorescence in LNCaP cells also showed co-localization of the CLC3 protein with tyrosine kinase 2 beta (PTK2B). Conclusion: DSF/Cu can activate chloride channels and induce apoptosis in LNCaP cells with the involvement of tyrosine kinase. These results provide new insights into the target therapy of prostate cancer.

How Pure and Hydrated Reline Deep Eutectic Solvents Affect the Conformation and Stability of Lysozyme: Insights from Atomistic Molecular Dynamics Simulations

Factors governing the stability and activity of proteins and enzymes in nonaqueous solvents have just been started to be explored. Because of their benign and economically viable nature, deep eutectic solvents (DESs) are being seen as an alternative media in many biotransformation processes. The present study exploits the changes in the conformation and stability of hen egg white lysozyme (HEWL) in the presence of reline (a eutectic mixture of choline chloride and urea) and reline/water mixtures using atomistic molecular dynamics simulations. The lysozyme structure was found to be partially folded in both reline and reline/water mixtures. Root-mean-square deviation (RMSD) of the positions of Ca atoms of lysozyme indicate that 50/50 reline/water solvent induces more destabilization in the conformation of HEWL than that by pure reline and 75/25 reline/water mixture. From the root-mean-square fluctuation (RMSF) analysis, it is found that the lysozyme active site (Glu35-Asp52) is quite stable in the presence of pure reline but it is least stable in the presence of 50/50 reline/water mixture. Our results show that the secondary structure of the lysozyme is significantly affected in the presence of reline. Our further analysis reveals that the hydrogen bonding interaction between HEWL-[Ch](+) dominates over HEWL-urea and HEWL-Cl- in pure reline than in reline/water mixtures.

A Case of Outpatient Hysterectomy in the Setting of Gitelman Syndrome

Gitelman syndrome is a rare autosomal recessive disorder involving a defect in the sodium-chloride cotransporter, which is expressed in the apical membrane of the distal convoluted tubule. Electrolyte abnormalities commonly occur in patients with Gitelman syndrome as a result, including hypokalaemia, hypomagnesemia, and metabolic alkalosis. As a result, the disorder may present with various clinical manifestations, including fatigue, weakness, muscle tetany, facial paresthesias, and a predisposition to the development of various ventricular arrhythmias. ks a result, the perioperative management of patients with this disorder presents unique challenges with regard to fluid and electrolyte management and the prevention and management of potential arrhythmias. In addition, the pharmacology of various anesthetics may present additional complexity with regard to perioperative management in this particular patient population. The following case presentation of a 42-year-old female with Gitelman syndrome undergoing elective outpatient hysterectomy for suspected endometriosis serves to illustrate the challenges that arise with regard to perioperative management in this particular patient population and demonstrates how they may be addressed.

Effectiveness of a formulation containing peptides and vitamin C in treating signs of facial ageing: three clinical studies

Objective Vitamin C and peptides are widely used in cosmetic products but there is a paucity of clinical studies showing that the formulations are effective in treating signs of facial ageing. These 3 clinical studies evaluated the effectiveness of an anti-ageing formula containing natural vitamin C (10%), biopeptides (rice and lupin), hyaluronic acid, and Vichy volcanic mineralising water, in amber glass ampoules with no preservatives (Peptide-C ampoules). Methods Dansyl chloride fluorescence labelling compared cell turnover for Peptide-C ampoules vs untreated skin in 32 female subjects. Study 2, an open clinical study, evaluated the efficacy on wrinkles of Peptide-C ampoules by investigator clinical scoring based on Dynamical Atlas visual assessment (N = 40) and subject self-assessment questionnaires (N = 47). Study 3, an open clinical study, evaluated wrinkles by instrumental quantification with 3D fringe projection analysis (N = 40) and subject questionnaires (N = 51). Results The mean cell turnover was faster for skin treated with Peptide-C ampoules compared to untreated skin (17.1 days vs. 19.2 days; P < 0.0001). In study 2, after 28 days application of Peptide-C ampoules, clinical grading of crow's-feet wrinkles, forehead wrinkles and nasolabial folds decreased by 9%, 11% and 5%, respectively (all P < 0.05 vs baseline). Of 47 subjects, 77%, 64% and 79% indicated their skin seemed smoothed out, fine lines were less visible, and skin complexion was more radiant, respectively. In study 3, the number of wrinkles decreased by 11.5% after 29 days application of Peptide-C ampoules vs baseline (P < 0.05) and 65% of subjects responded the fine lines were less visible. Conclusion This formulation of a combination of anti-ageing ingredients in ampoules, allowing a minimalist formula, showed significant results on improving facial wrinkles and radiance.

The Totality of Evidence and Use of ABP 215, a Biosimilar to Bevacizumab

ABP 215 (MVASI (TM), Amgen, Thousand Oaks, CA; MVASI (TM), Amgen Europe B.V., Netherlands) is a biosimilar to bevacizumab (Avastin(R), Genentech, South San Francisco, CA) reference product (RP), a monoclonal antibody targeting vascular endothelial growth factor A (VEGF-A). Here we provide a brief overview of the totality of evidence that supported the approval of ABP 215, along with practical considerations to ensure safe and effective administration. ABP 215 has been shown to be highly similar to the RP, with similar mechanism of action, analytical (structural and functional) characteristics, binding, and potency. The similarity of PK parameters of ABP 215 and bevacizumab RP has been confirmed in healthy volunteers. In a comparative clinical trial, patients with stage IV or recurrent non-squamous non-small cell lung cancer receiving carboplatin and paclitaxel were randomized to ABP 215 or bevacizumab RP. No clinically meaningful differences were found between ABP 215 and RP. The objective response rate (ORR) was 39% for ABP 215 and 41.7% for bevacizumab RP. The risk ratio for the ORR was 0.93 [90% confidence interval (CI), 0.80-1.09], which fell within the prespecified margin for equivalence of 0.67-1.5, indicating similar clinical efficacy. Similar to bevacizumab RP, ABP 215 is supplied as a clear to slightly opalescent, colorless to pale yellow, sterile solution in a glass vial. It should be diluted in 0.9% sodium chloride in polyvinylchloride or polyolefin bags before administering as an intravenous infusion. The ABP 215 solution should be stored at 2-8 degrees C (36-46 degrees F) prior to use. Physicochemical stability studies showed that there were no meaningful changes in purity or potency and no loss of protein after storage at 2-8 degrees C for 35 days followed by storage at 30 degrees C for 48 h.

Anesthetic potential of the essential oils of Aloysia triphylla, Lippia sidoides and Mentha piperita for Colossoma macropomum

The aim of this study was to evaluate the anesthetic potential of the essential oils of Aloysia triphylla (EOAT), Lippia sidoides (EOLS) and Mentha piperita (EOMP) in relation to juvenile tambaqui (Colossoma macropomum), based the swimming behavior of these fish and possible histopathological damage to the gills. To induce anesthesia, juvenile tambaqui (130.55 +/- 22.4 g; 16.8 +/- 0.95 cm) were individually exposed to different concentrations of the essential oils (EOAT: 5, 10, 20, 40, 60, 80 and 150 mg L-1; EOLS: 2, 5, 10, 20, 30, 40 and 50 mg L-1; EOMP: 5, 10, 20, 40, 60, 70 and 90 mg L-1), for exposure periods of between four minutes and six hours. The three essential oils evaluated presented anesthetic properties. The concentration intervals over which the fish reached all the stages of anesthesia (1, 2, 3a, 3b and 4) were between 40 and 150 mg L-1 for EOAT; 20 and 50 mg L-1 for EOLS; and 40 and 90 mg L-1 for EOMP. The times taken to reach the anesthesia stages were inversely proportional to the increases in the concentration of the essential oils. The histopathological damage to the gills of the tambaqui that resulted from using essential oil concentrations that were defined as anesthetic (150 mg L-1 EOAT, 30 mg L-1 EOLS and 90 mg L-1 EOMP) were also evaluated. The main damage recorded was hypertrophy and hyperplasia of the lamellar epithelium, lamellar fusion and proliferation of chloride cells. According to the histopathological alteration index (HAI), there were no irreversible damage (such as fibrosis and necrosis) to the gills of the tambaqui. However, while EOLS and EOMP caused mild damages in the gills, the EOAT generated more severe damages. Overall, for the tambaqui, the essential oils of A. triphylla, L. sidoides and M. piperita are efficient anesthetic in the doses of 150, 30 and 90 mg L-1, respectively.

Antibiotics, algal evaluations and subacute effects of abattoir wastewater on liver function enzymes, genetic and haematologic biomarkers in the freshwater fish, Clarias gariepinus

Abattoirs are positioned close to freshwaters in most developing countries where untreated wastewaters are discharged into with potential risk to aquatic life such as fish and ultimately human health. We assessed physicochemical parameters, antibiotics (oxytetracycline and diclofenac) and algal load of effluent collected from a major abattoir in Nigeria. Furthermore, liver function enzymes, genotoxic and haemotoxic effects of subacute concentration (10% of 96 hLC(50) value) of the wastewater were evaluated over a period of 28 d in Clarias gariepinus (The African Sharptooth Catfish). The 96 hLC(50) value of the abattoir wastewater against C. gariepinus was 154.14 mL/L (15.4%). Nitrates, phosphates, sulphates, chloride, ammonia, TDS, TSS, BOD5 and heavy metals (Fe and Pb) in the wastewater were above permissible limits while diclofenac and oxytetracycline were below detection limit (BDL). Microalgae in the wastewater were mostly Bacilliariophyta (Navicula spp.) (45.64%) and euglenoids (Euglena and Phacus spp.) (49.48%). Liver function enzymes (LDH, AST, ALT) level were higher in exposed fishes except for ALP which was lower at day 28 compared to control levels. Erythrocytic genotoxic indices (nuclear abnormalities) were significantly higher (p < 0.05) in the exposed fishes particularly at day 28 compared to control. Haematologic indices level such as WBC, MCV MCH, MCHC increased significantly (p < 0.05) while lymphocytes, HGB, RBC, HCT levels decreased significantly (p < 0.05) in the exposed C. gariepinus by day 28 compared to control. These results demonstrate potential adverse effects posed to aquatic fish species in the Ogun River by the discharge of the abattoir effluent. The microalgae species identified in the effluent may be explored for pre-treatment of the effluent before discharge in order to prevent eutrophication and increased pollutant load in the River. The study results will contribute to evidence-based environmental risk management of the River which is relevant to the UN SDGs 6 (clean water and sanitation), 11 (sustainable cities and communities) and 14 (sustaining life below water).

Uranium(VI) toxicity in tobacco BY-2 cell suspension culture – A physiological study

For the first time, the physiological and cellular responses of Nicotiana tabacum (BY-2) cells to uranium (U) as an abiotic stressor were studied using a multi-analytic approach that combined biochemical analysis, thermodynamic modeling and spectroscopic studies. The goal of this investigation was to determine the U threshold toxicity in tobacco BY-2 cells, the influence of U on the homeostasis of micro-macro essential nutrients, as well as the effect of Fe starvation on U bioassociation in cultured BY-2 cells. Our findings demonstrated that U interferes with the homeostasis of essential elements. The interaction of U with BY-2 cells confirmed both timeand concentration-dependent kinetics. Under Fe deficiency, a reduced level of U was detected in the cells compared to Fe-sufficient conditions. Interestingly, blocking the Ca channels with gadolinium chloride caused a decrease in U concentration in the BY-2 cells. Spectroscopic studies evidenced changes in the U speciation in the culture media with increasing exposure time under both Fe-sufficient and deficient conditions, leading us to conclude that different stress response reactions are related to Fe metabolism. Moreover, it is suggested that U toxicity in BY-2 cells is highly dependent on the existence of other micro-macro elements as shown by negative synergistic effects of U and Fe on cell viability.
