Enhanced degradation of atrazine from soil with recyclable magnetic carbon-based bacterial pellets: Performance and mechanism

Herein, magnetic biochar coupled with Acinetobacter lwoffii DNS32 immobilized pellets (DMBC-P) were synthesized through sodium alginate embedding and fixation, which could fast and completely eliminate atrazine from contaminated farmland soil. Characterization results revealed that DMBC-P exhibited a significant abundance of three-dimensional network porous structures, thereby enhancing the stability and specific surface area of DMBC-P. The application of 0.5 % DMBC-P could completely remove 22 mg/kg atrazine from soil within 4 d under the condition of moisture content of 60 % and soil pH of 7.4. After 5 d of remediation, DMBC-P could be easily extracted from the soil by magnetic separation and still had 100 % removal efficiency for atrazine after 3 rounds of recycling. Moreover, DMBC-P effectively alleviated the oxidative damage of atrazine to soybean seedlings through significantly decreasing the activities of various plants antioxidant enzymes by 27 % to 79 %. Meanwhile, analysis of 16S rRNA revealed a significant increase in the relative abundance of functional microflora such as Acidobacteriota and Chloroflexi at the phylum level, which promoted the growth of soybean seedlings. Additionally, pore filling, hydrogen bonding, and π-π stacking were identified as the primary mechanisms responsible for atrazine adsorption onto DMBC-P. Subsequently, the degrading bacteria DNS32 immobilized on DMBC-P was employed to catalyze the decomposition of atrazine into non-toxic cyanuric acid based on LC-MS. Overall, this study provided a reasonable design of magnetic carbon-based bacterial pellet for atrazine-contaminated soil remediation, which could efficiently remove atrazine and be effectively recycled after remediation.

Adaptive Auricular Point Acupressure for Sleep Disturbance in Women with Breast Cancer: A Randomized Controlled Trial

The study aimed to evaluate the preliminary effect and efficacy of auricular point acupressure (APA) on the quality of sleep in women with breast cancer who were undergoing chemotherapy. Sample & Setting. We conducted a randomized controlled trial on 68 patients with breast cancer who reported poor sleep quality based on the Pittsburgh Sleep Quality Index (PSQI) scores (>7). Methods & Variables. Participants were randomly assigned to an APA treatment group or a control group. Patients in the APA group had magnetic pellets attached to selected auricular points and were instructed to apply pressure to these points 4×/day for three consecutive weeks. We objectively measured sleep quality using the Actiwatch Spectrum and the PSQI at the baseline and postintervention. Statistical analyses of changes in sleep data were performed using the t-test, a rank-sum test, and analyses of covariance. In patients treated with APA, the PSQI total score and sleep onset latency had significantly decreased, while the total sleep time and sleep efficiency had significantly increased. Although the total PSQI score differed between groups at the baseline, ANCOVA results showed that the APA group had a significantly lower total PSQI score. APA could be an inexpensive and effective approach to improving sleep quality and reducing sleep disturbance in patients with breast cancer. Further research needs a larger sample size to verify our findings.

Denitrifying bacteria immobilized magnetic mycelium pellets bioreactor: A new technology for efficient removal of nitrate at a low carbon-to-nitrogen ratio

This study integrated spores and magnetite (Fe3O4) to form magnetic mycelium pellets (MMP) as bio-carriers immobilized with denitrifying bacteria in a bioreactor. Different carbon-to-nitrogen (C/N) ratios and hydraulic retention time (HRT) were established for investigating the performance of the bioreactor. The nitrate removal efficiency was 98.14% at C/N = 2.0 and HRT = 6 h. Gas chromatography (GC) results indicated that the main component of the produced gas was N2. Fe3O4 was well-integrated into MMP according to X-ray diffraction (XRD) results and infrared spectrometer (FTIR) analysis. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) showed that bacteria were successfully immobilized on MMP. Fluorescence excitation-emission matrix (EEM) indicated that functional bacteria GF2 might enhance the metabolic activity of the microbial community in the bioreactor and microbial activity was highest at C/N = 2.0. Pseudomonas stutzeri sp. GF2 might be immobilized and had a major role in the bioreactor according to high throughput sequencing results.

Preparation, Characterization and Decolorization Performance of Magnetic Adsorbent Pellets Formed by the Utilization of Electric Flocculation Sludge

AbstractA new magnetic adsorbent pellets(MP) was prepared with electric flocculation sludge as raw material by technologies of alkaline impregnation, heat activation and composition with vermiculite. Its decolorization performance for treating methylene blue (MB) dye wastewater is studied, and its structure was analyzed by FTIR, XRD, SEM, XPS, BET and magnetic hysteresis curve. The results showed that the best prepare condition of MP is that impregnation time of 15 % KOH solution is 48 h and a subsequent calcination at 600 °C for 60 min, m(vermiculite)/m(sludge)=1.0. Characterization analysis illustrates that the activated sludge and vermiculite has been successfully composited. And the organic waste in sludge is converted into activated carbon and the iron species are transformed into Fe3O4. It has mesoporous structure and magnetic property and can be separated from the solution by an external magnetic field. In addition, MP was effective on treating MB wastewater, the decoloration is 85 % at the dosage of 10 g L−1 when the contact time is 84 h and the initial concentration of dye is 10 mg L−1 and 20 mg L−1. The sludge utilization technology investigated in this work is a new process which could reduce the emission, protect the environment and yield the useful by‐product.

Enhanced removal of trivalent chromium from leather wastewater using engineered bacteria immobilized on magnetic pellets

Leather wastewater contains various toxic contaminants, with trivalent chromium (Cr(III)) having high concentration and adversely affecting wastewater treatment. In this study, a Cr(III) adsorption protein (MerP) was displayed on the cell surface of Escherichia coli and then coupled with a magnetic pellet system to facilitate Cr(III) adsorption. The results showed the engineered strain M-BL21 achieved an in vitro Cr(III) adsorption capacity of 2.38 mmol/g. Next, the magnetic pellets were prepared as component ratios of sodium alginate (2.5%), polyvinyl alcohol (8%), Fe3O4 nanoparticles (3.5%), and M-BL21 at 3 g/L. The optimized system was capable of Cr(III) adsorption at an efficiency of 91.29%, which was substantially higher than that of the magnetic carrier alone (67%). Results of scanning electron microscopy with energy-dispersive X-ray analysis proved that Cr(III) was absorbed on the magnetic pellet. The recyclable performance of magnetic property (13.34185 emu/g) and high Cr(III) adsorption efficiency (68.75%) remained after five cycles of Cr(III) absorption. In the medium-scale experiment, 25 L of leather wastewater were treated with magnetic pellet and the Cr(III) removal efficiency reached 88.2%. Thus, our results present an advanced, fully operational, and eco-friendly method for in situ removal of Cr(III) from contaminated wastewater.

1032 Auricular Point Acupressure for Sleep Disturbance in Women With Breast Cancer: A Pilot Randomized Controlled Trial

Abstract Introduction Sleep disturbance is reported in up to 60% of cancer patient. In traditional Chinese medicine, evidence suggests that auricular point acupressure (APA) improves sleep. However, little is known about APA’s effect on sleep disturbance in patients with breast cancer (BC). We tested the preliminary efficacy of APA on sleep in BC women undergoing chemotherapy. Methods A pilot randomized controlled trial was conducted in 41 BC patients (mean age=50±14) with self-reported poor sleep [Pittsburgh Sleep Quality Index (PSQI)≥7]. Participants were randomly assigned to an APA group (n=22) and a control group (n=19). All patients received sleep hygiene education. Additionally, for the APA group, magnetic pellets were attached to selected auricular points once a week for 3 weeks at the clinic, and the participants were instructed to self-press the pellets 4 times a day. Sleep were objectively measured by Actiwatch Spectrum and subjectively using PSQI at baseline and post-intervention. Paired t-tests and analyses of covariance using the variable baseline values were used to examine changes in sleep parameters. Results Twenty-one participants from the APA and sixteen from the control groups completed the study. Within the APA group, PSQI [mean difference (MD)=3.85, 95% Confidence Interval (C)=3.12~4.60] and sleep onset latency (MD=18.02, 95%CI=5.96~30.09) were significantly decreased, and the sleep duration (MD=-0.53, 95%CI=-0.99~-2.35) and sleep efficacy (MD=-5.00, 95%CI=-8.72~-1.28) were significant increased at post-intervention. Compared to the control group, participants in the APA group had significantly lower PSQI (F=30.77, p<0.001) and greater sleep efficacy (F=5.25, p=0.028) at post-intervention. Conclusion APA may be an inexpensive and effective approach to improve sleep in patients with BC. More rigorous research with larger samples is needed to further test the efficacy of APA on promoting sleep in BC patients. Support None

Recovery of magnetite from fluidized-bed homogeneous crystallization of iron-containing solution as photocatalyst for Fenton-like degradation of RB5 azo dye under UVA irradiation

Iron recovery from wastewater as magnetite (Fe3O4) pellets was performed in a fluidized-bed homogeneous crystallization (FBHC) process. The catalytic effectiveness of magnetite in the heterogeneous degradation of RB5 azo dye was evaluated. The key parameters of FBHC, including effluent pH, cross-section loading (L, kg/m2.h), initial iron concentration ([Fe(II)], mg/L), and inlet supersaturation (S), were optimized to maximize the total iron removal (TR, %) and crystallization ratio (CR, %) from a fluidized-bed reactor. Under the conditions of pH = 8.5–9.5 and [Fe(II)]in = 100 – 500 mg/L, the TR and CR values reached 99% and 77%, respectively. The magnetization and coercivity of the recovered Fe3O4 pellets were analyzed to confirm the magnetic characteristic. A Fenton-like degradation of RB5 azo dye was activated using the Fe3O4 pellets under UVA irradiation, pH = 2.75 – 3.0, initial peroxide concentration of 10 mM, and catalyst loading of 2 g/L. The efficiencies of decolorization and mineralization reached about 98 – 99% and 60 – 68%, respectively. FBHC method benefited the recovery of high-purity metal oxides and the production of a low quantity of sludge. Magnetic pellets transformed from the dissolved iron in wastewater were promising materials to reuse as a photochemical reactant for organic pollutant degradation.

Gastrointestinal motility and morphology in mice: Strain-dependent differences.

BALB/c and C57BL/6mice are widely used in biomedical research; however, the differences between strains are still underestimated.Our aims were to develop an experimental protocol to evaluate the duodenal contractility and gastrointestinal transit in miceusing theAlternating Current Biosusceptometry (ACB)techniqueand to compare gastrointestinal motor function and morphology between BALB/c and C57BL/6 strains. Male mice wereused inexperiments (a) duodenal contractility: animalswhich had a magnetic marker surgically fixed in the duodenum to determine the frequency and amplitude of contractions and (b) gastrointestinal transit: animals which ingested a magnetically marked chowto calculate theOro-Anal Transit Time (OATT) and the Fecal Pellet Elimination Rate (FPER). The animals were killedafter the experiments for organ collection andmorphometric analysis. BALB/c and C57BL/6 had two different duodenal frequencies (high and low)with similar amplitudes. After 10hours of monitoring, BALB/c eliminated around 89% of the ingestedmarker and C57BL/6 eliminated33%; OATT and FPER were slower for C57BL/6 compared with BALB/c. The OATT and amplitude of low frequencyhad a strong positive correlation in C57BL/6. For BALB/c, thegastric muscular layer was thickercompared to that measured for C57BL/6. The experimental protocolto evaluate duodenal contractility and fecal magnetic pellets output using the ACB techniquein micewas successfully established.BALB/c strains had higher duodenal frequencies and a shorter timeto eliminate the ingested marker. Our resultsshowed differences in bothmotor function and gastrointestinal morphology betweenBALB/c and C57BL/6 strains.

RETRACTED ​ARTICLE: Synthesis of Magnetic Composites Based on Waste Low Density Polyethylene Wax and Iron Oxide Nanoparticles for Methyl Green Adsorption

Magnetic nanoparticle composites were prepared from iron oxide (magnetite) (Fe3O4) and waste low density polyethylene wax (WLDPEW) via gamma irradiation technique using 60Co source, followed by anchoring Fe3O4 on the surface of WLDPEW samples to produce WLDPEW–Fe3O4 nanoparticle magnetic composite pellets. The outcome WLDPEW and WLDPEW–Fe3O4 nanoparticle magnetic composite pellets were characterized by Fourier transform infrared spectroscopy, X-ray diffraction (XRD), scanning electron microscope-energy dispersive X-ray spectrometry, high resolution transmission electron microscopy (HR-TEM) and electron spinning resonance (ESR). The results of HR-TEM and XRD showed that the presence of Fe3O4 nanoparticles. HR-TEM photomicrographs of the Fe3O4 into WLDPEW showed that the nanoparticles of Fe3O4 have the average diameter ranged from ~30 to ~50 nm. The EDS spectra showed strong peaks of Fe and O. The ESR spectra exposed the paramagnetic properties of WLDPEW–Fe3O4 nanoparticle magnetic composite pellets. The WLDPEW–Fe3O4 nanoparticle magnetic composite pellets were exploited in adsorption of methyl green dye from aqueous solutions at various conditions. The kinetics and the adsorption isotherms were studied. Through results it was observed that the adsorption capacity of WLDPEW–Fe3O4 nanoparticle magnetic composite pellets is 18.5 mg g−1. Therefore, WLDPEW–Fe3O4 nanoparticle magnetic composite pellets could be used in removing dyes from their aqueous solutions.

Self-immobilization of a magnetic biosorbent and magnetic induction heated dye adsorption processes

Biosorbents for wastewater treatments is one of the most widely studied techniques in environmental and bioresource research. A marine-derived Penicillium janthinellum strain fungus was used in this study to prepare self-immobilized mycelial pellets. Fe3O4 nanoparticles were added in the culturing media, which were automatically incorporated in the mycelial pellets during culturing process to endow the pellets with magnetic properties. These magnetic mycelial pellets were used as biosorbents for water treatments, and their morphology was characterized by microscopic observation, Energy dispersive X-ray analysis, Fourier transform infrared spectroscopy and thermal gravimetric analysis. The effects of nanoparticles in culture media on pellet formation were discussed and the content of nanoparticle in culturing media was optimized. Study on Congo red adsorption from aqueous solutions showed that the pellets with 71.6wt% Fe3O4 nanoparticles had a maximum adsorption capacity of 102.4mg/g pellets (360.6mg/g mycelia), and the solution heated by magnetic induction showed faster adsorption rates than that of bulk liquid heating processes under the same adsorption temperature. These pellets were easily separated by magnetic forces and the magnetic induction heating is beneficial in energy saving when comparing to traditional heating processes.

Efficacy of auriculotherapy for constipation in adults: a systematic review and meta-analysis of randomized controlled trials.

To assess the clinical evidence of auriculotherapy for constipation treatment and to identify the efficacy of groups using Semen vaccariae or magnetic pellets as taped objects in managing constipation. Databases were searched, including five English-language databases (the Cochrane Library, PubMed, Embase, CINAHL, and AMED) and four Chinese medical databases. Only randomized controlled trials were included in the review process. Critical appraisal was conducted using the Cochrane risk of bias tool. Seventeen randomized, controlled trials (RCTs) met the inclusion criteria, of which 2 had low risk of bias. The primary outcome measures were the improvement rate and total effective rate. A meta-analysis of 15 RCTs showed a moderate, significant effect of auriculotherapy in managing constipation compared with controls (relative risk [RR], 2.06; 95% confidence interval [CI], 1.52- 2.79; p<0.00001). The 15 RCTs also showed a moderate, significant effect of auriculotherapy in relieving constipation (RR, 1.28; 95% CI, 1.13-1.44; p<0.0001). For other symptoms associated with constipation, such as abdominal distension or anorexia, results of the meta-analyses showed no statistical significance. Subgroup analysis revealed that use of S. vaccariae and use of magnetic pellets were both statistically favored over the control in relieving constipation. Current evidence illustrated that auriculotherapy, a relatively safe strategy, is probably beneficial in managing constipation. However, most of the eligible RCTs had a high risk of bias, and all were conducted in China. No definitive conclusion can be made because of cultural and geographic differences. Further rigorous RCTs from around the world are warranted to confirm the effect and safety of auriculotherapy for constipation.

Complementary effects of auricular acupressure in relieving constipation symptoms and promoting disease-specific health-related quality of life: A randomized placebo-controlled trial

Constipation has been identified as a worldwide health problem among elderly people. Currently, it is not effectively relieved by the use of laxatives and lifestyle modification. Previous studies reported promising results in managing constipation with auricular acupressure (AA), although its effectiveness was not affirmed. This study is to evaluate the complementary effects of AA in relieving constipation symptoms and in promoting disease-specific health-related quality of life (HRQOL) among elderly residential care home (RCH) residents in Hong Kong. Randomized placebo-controlled trial. Elderly RCH. Ninety-nine participants were randomly assigned to either experimental group (AA using auricular plasters with magnetic pellets), placebo-controlled group (AA using auricular plasters with Semen Vaccariae), or usual care group (AA using auricular plasters only). AA was applied onto seven auricular acupoints for 10 days. Constipation symptoms and disease-specific HRQOL were measured before AA, at the completion of AA (D10), and at the 10th-day follow-up time (D20). Significant group×time interaction effect was found in the change of satisfaction subscale between the experimental group and placebo-controlled group at D10 (p=0.016) and D20 (p=0.016) relative to the baselines. For both constipation symptoms and disease-specific HRQOL, the experimental group demonstrated the greatest improvement after receiving AA at both D10 and D20 compared with the other two groups. The current findings indicated positive clinical value of AA with magnetic pellets in managing constipation in elderly RCH residents. AA was also found to be a safe and acceptable intervention.

The stimulation effect of auricular magnetic press pellets on older female adults with sleep disturbance undergoing polysomnographic evaluation.

Study Objectives. To examine the stimulation effect of auricular magnetic press pellet therapy on older female adults with sleep disturbance as determined by polysomnography (PSG). Design. Randomized, single-blind, experimental-controlled, parallel-group. Setting. Community. Participants. Twenty-seven older female adults with sleep disturbance according to the Pittsburgh Sleep Quality Index (PSQI) >5 for at least 3 months were recruited. Participants were screened by both the Hospital Anxiety and Depression Scale (HADS) and the Mini-Mental State Examination (MMSE), as well as polysomnography prior to randomization. Interventions. All eligible participants were randomly allocated into the experimental or control group. Both groups were taped with magnetic press pellet on auricular points for 3 weeks. The experimental group was treated by applying pressure on the magnetic press pellets 3 times per day while no stimulation was applied on the control group. Measurements and Results. Both groups were measured by PSG and PSQI at the beginning of the study and 3 weeks after the study. Both groups showed improvements on PSQI scores compared to the baseline. One-way analysis of covariance adjusted for baseline scores showed that significant improvements of PSG-derived sleep parameters, such as sleep efficiency, were found in the experimental group. However, no significant differences between groups were observed in the proportion of sleep stages with the exception of Stage 2. Conclusions. Auricular therapy using magnetic pellets and stimulation by pressing was more effective in improving the sleep quality compared to auricular therapy without any stimulation.

AC Biosusceptometry Technique to Evaluate the Gastrointestinal Transit of Pellets under Influence of Prandial State

Multiparticulate dosage forms have been proposed when distal regions of gastrointestinal tract are desirable as target of drugs. It is known that physiological parameters might interfere with the processes related to the drug delivery and absorption and therefore, it is essential to evaluate the behavior of such delivery systems in vivo. The aim of this study was to propose the AC Biosusceptometry technique as a noninvasive and radiation free device to evaluate the gastrointestinal transit of a magnetic multiparticulate dosage form in healthy volunteers under fasting and fed conditions. Magnetic pellets were prepared by the powder layering method of ferrite on nonpareils sugar beads and coated by using Eudragit®. Our data showed that the AC Biosusceptometry technique was able to monitoring the gastrointestinal transit of pellets presenting similar profiles as demonstrated by standard techniques. Food intake has markedly influenced the gastric emptying as well as the colon arrival and the small intestine transit of magnetic pellets. © 2009 Wiley-Liss, Inc. and the American Pharmacists Association J Pharm Sci 99:317–324, 2010

Auricular acupuncture for insomnia: a systematic review

Auricular acupuncture (AA) is a therapeutic method by which specific points on the auricle are stimulated to treat various conditions. AA is often recommended as treatment for insomnia. The aim of this systematic review was to evaluate data from randomised, placebo-controlled clinical trials testing the effectiveness of AA for treating insomnia. We searched the literature using 18 databases from their inception to April 2008 without language restrictions. All prospective randomised clinical trials (RCTs) of AA for subjects with insomnia were considered. Methodological quality was assessed using the Jadad score. We identified 433 possible relevant articles, in which include 10 acceptable RCTs. The methodological quality of the trials was generally poor. Magnetic pellets AA was compared with placebo AA in three of the studies. The results suggested beneficial effects on sleep efficiency compared with placebo AA. One RCT tested needle AA compared with placebo AA and failed to show the effectiveness of AA. Four RCTs compared Semen Vaccariae or magnetic pellet AA with conventional drugs (estazolam or diazepam). Favourable effects for AA were found. Two RCTs tested thumbtack needle AA vs. no treatment suggested beneficial effects of AA on a sleep score. We conclude that, because of the paucity and of the poor quality of the data, the evidence for the effectiveness of AA for the symptomatic treatment of insomnia is limited. Further, rigorously designed trials are warranted to confirm these results.

Longitudinal changes in the disability level of the elders with low back pain after auriculotherapy

To evaluate the longitudinal changes in the disability level of elders with LBP after receiving auriculotherapy. Randomized controlled trial. Sixty participants who were 60 years old or above and who were suffering from LBP were recruited from five hostels for the elders in Hong Kong. The participants were randomly allocated to receive a 3-week session of auriculotherapy using either semen vaccariae (control group=30) or magnetic pellets (experimental group=30). Seven auricular acupoints that are expected to have an effect on LBP were selected. Assessment data were collected at five points of time: (i) baseline, (ii) about 1.5 weeks of treatment, (iii) 3 weeks of treatment, (iv) 2 weeks post-treatment, and (v) 4 weeks post-treatment using the modified Aberdeen low back pain disability scale (Chinese). When the rate of change was compared between the two groups at each point of time starting from the baseline, those in the experimental group demonstrated significant improvement in the overall disability level, pain/sensation, and physical and functional abilities at 1.5 weeks of treatment (p<0.001), 3 weeks of treatment (p<0.001), 2 weeks post-treatment (p<0.001), and 4 weeks post-treatment (p<0.001). Longitudinal changes in the improvement of disability level were found among the elders with low back pain after receiving auriculotherapy using magnetic pellets.

Auriculotherapy on low back pain in the elderly

The objective of the study was to examine the effectiveness of auriculotherapy using magnetic pellets for the elderly suffering from low back pain (LBP). Sixty participants who were 60-years old or above and had been suffering from LBP were recruited. Participants were randomly allocated to receive auriculotherapy on a 3-week basis using either Semen Vaccariae (control group=30) or magnetic pellets (experimental group=30). Seven auricular acupoints that are believed to have an effect on LBP were selected. Treatment effects were evaluated using the Chinese Pain Intensity Verbal Rating scale (VRS). The experimental group had indeed experienced a significant improvement in pain relief when compared with the control group; and the therapeutic effects were sustained at 2 and 4-week follow-up periods after the therapy. Findings of this study demonstrated that auriculotherapy using magnetic pellets significantly reduce the pain intensity level of the elderly suffering from non-specific LBP.
