Our findings revealed MIPP-based bioremediation supplied with 10 mM Ca2+ could increase the Cd removal and could potentially be applied for Cd remediation.We have investigated the interaction of the actinide Cm(III) and its lanthanide homologue Eu(III) with cells of Brassica napus in suspension. This study combines biochemical techniques (plant cell response) with spectroscopic experiments to determine the chemical speciation of hazardous metals in contact with the plant cells. Experiments conducted over a period of 7 d showed that B. napus cells were able to bioassociate both potentially toxic metals in significant amounts up to 0.58 µmol Eu/gfresh cells and 1.82 µmol Cm/gfresh cells at 30 µM Eu(III) and 0.68 µM Cm(III), respectively. For Cm(III), a biosorption process could be identified as soon as 5 h post-exposure with 73 ± 4% of the Cm(III) bioassociated. Tiplaxtinin PAI-1 inhibitor Luminescence spectroscopy results based on UV and site-selective excitation confirmed the existence of three Cm(III)/Eu(III) [M(III)] species in both the supernatants and cells. The findings detailed herein support that M(III) coordinates to two kinds of carboxyl groups and phosphate groups.A novel metal-free catalyst consisting of typical flower-like graphitized polyimide (g-PI) is first synthesized via an enhanced hydrothermal polymerization process, and it exhibits excellent performance for pollutant removal through peroxymonosulfate (PMS) activation over a wide pH range (3-11). The catalyst is especially effective for attacking the endocrine disruptor bisphenol A (BPA), which can be completely degraded in a short time. Based on the results of characterization, g-PI is consisted of abundant aromatic frameworks with π conjugates based on C-O-C linkages and N-hybrid rings, which play essential roles in the subsequent degradation of pollutants. In the g-PI/PMS/BPA system, BPA (rich in π bonds) is preferentially adsorbed to the catalyst surface through π-π interactions, accompanied by a decrease in its activation energy to produce surface-adsorbed BPA*. This species can be directly attacked and degraded by PMS without the need for the radical processes, which saves the energy required for the intermediate activation process of PMS. On the other hand, the electrons obtained from pollutants are rapidly transferred to the O center, driving PMS activation to generate free radicals. The synergetic interface process offers excellent potential for practical wastewater purification.Both soil erosion and soil contamination pose critical environmental threats to the Chinese Loess Plateau (CLP). Green, efficient and feasible remediation technologies are highly demanded to meet these challenges. Herein we propose a unique "soil for soil-remediation" strategy to remediate the heavy metal polluted soil in CLP by converting loess into zeolite for the first time. With a simple template-free route, the natural loess can be converted into cancrinite (CAN) type of zeolite. A highly crystalline CAN was obtained via hydrothermal treatment at 240 oC for 48 h, with a precursor alkalinity of Na/(Si+Al)> 2.0. The as-synthesized CAN zeolite exhibits excellent remediation performance for Pb(II) and Cu(II) polluted soil. Plant assay experiment demonstrates that CAN can significantly restrain the uptake and accumulation of Pb(II) and Cu(II) ions in vegetables, with a high removal efficiency up to 90.7% and 81.4%, respectively. This work demonstrates a "soil for soil-remediation" strategy to utilize the natural loess for soil remediation in CLP, which paves the way for developing green and sustainable remediation eco-materials with local loess as raw materials.Twin studies have consistently found that genetic factors explain a substantial proportion of the variance for insomnia. However, studies vary widely in their heritability estimates. Therefore, this meta-analysis aimed to 1) Estimate the mean heritability of insomnia; 2) Assess heterogeneity among twin studies of insomnia; and 3) Search and analyse characteristics of the studies (moderator variables) that may explain heterogeneity among estimates. For this purpose, separate meta-analyses were carried out for MZ and DZ correlations and for heritability estimates by assuming random-effects models. Thirteen independent samples were included in this meta-analysis. The heterogeneity index for heritability estimates was significant in both best fitting models (I2 = 98.77, P less then .0001) and full models (I2 = 97.80, P less then .0001). MZ correlations were higher (0.37; 95%CI 0.31,.43) than DZ correlations (0.15; 95%CI 0.12,.18). A mean heritability of 0.39 (95%CI 0.32,.44) was found for insomnia. These results highlight the role of genetic factors in explaining differences among the population on insomnia and Emphasize heterogeneity among studies. Further research is needed to identify variables that could explain this heterogeneity.

Embryonal tumors with multilayered rosettes (ETMR) is an extremely rare and highly aggressive tumor. It includes three distinct entities i.e, embryonal tumor with abundant neuropil and true rosettes (ETANTR), ependymoblastoma (EBL) and medulloepithelioma (MEPL). Here, we present our institutional experience of seven ETMR cases treated over a period of five years.

Patients' records from 2015 to 2019 were reviewed manually and electronically to retrieve the data. Clinicopathological and outcome details of ETMR cases were entered in a predesigned proforma.

A total of seven cases of ETMR were registered from 2015 to 2019 with a median age at presentation of four years (range 3-7 years). All patients underwent surgery. However, only three patients completed the planned adjuvant treatment, comprising of focal radiotherapy (RT) alone, craniospinal irradiation (CSI) alone and CSI followed by six cycles of chemotherapy in one patient each respectively. Two patients commenced CSI but deteriorated during RT and thereafter needed best supportive care. Two patients could not be started on any adjuvant treatment. Unfortunately, six patients succumbed to their disease within one year of their diagnosis. Only one patient who received both CSI and adjuvant chemotherapy is alive at 15 months of diagnosis.

ETMR is a rare and aggressive entity. Majority of the patients die within one year of the diagnosis despite multimodality treatment.

We systematically searched PubMed, EmBase, and the Cochrane library for eligible studies throughout October 2018 in this meta-analysis. The clinical characteristics of PD patients presented with probably RBD, confirmed RBD, or non-RBD were analyzed. The pooled odds ratios and weighted mean differences with corresponding 95 % confidence intervals were calculated for categories and continuous data, respectively. All the pooled analyses were conducted using random-effects model. Forty-seven studies recruited a total of 8019 PD patients were included in the final meta-analysis. The summary results indicated significant differences between probable RBD and non-RBD for PD duration, levodopa dosage daily, Hoehn-Yahr stage, UPDRS-III, UPDRS-motor score, UPDRS activity of daily livinghensive differences in the patients' characteristics among probable RBD, confirmed RBD, and non-RBD in PD patients.In situ studies using transmission electron microscopy (TEM) can provide insights to how properties, structures and compositions of nanostructures are affected and evolving when exerted to heat or chemical exposure. While high-resolved imaging can be obtained continuously, at video-framerates of hundreds of frames per second (fps), compositional analysis struggles with time resolution due to the long acquisition times for a reliable analysis. This especially holds true when performing mapping (correlated spatial and compositional information). Hence, transient changes are difficult to resolve using mapping. In this work, the time-resolution of sequential mapping using scanning TEM (STEM) and energy dispersive spectroscopy (EDS) is improved by acquiring spectrum images during short times and filtering the spectroscopic data. The suggested algorithm uses regularization to smooth and prevent overfitting (known from compressed sensing) to fit model spectra to the data. The algorithm is applied on simulations as well as acquisitions of catalyzed crystal growth (nanowires), performed in situ in a specialized environmental TEM (ETEM). The results show the improved temporal resolution, where the compositional progression of the different regions of the nanostructure is revealed, here with a time-resolution as low as 16 s compared to the minutes usually needed for similar analysis.

Historically, aggressive fluid resuscitation has been a cornerstone of management of hemorrhagic shock in pediatrics. Adult data suggest this strategy may be harmful. We sought to determine whether aggressive fluid resuscitation within the first hour of presentation to the emergency department in pediatric patients with trauma is associated with worse clinical outcomes.

We performed a retrospective cohort study from 2012 to 2017 at a single pediatric level 1 trauma center. We defined three patient cohorts ≤ 20cc/kg (reference), 20-40 (20.01 to 39.99) cc/kg, and ≥40cc/kg of intravenous fluid (IVF) given in the first in-hospital hour. Covariates included age, injury severity score, shock index (adjusted for age), and mechanism of injury and were adjusted for with multivariable regression. The primary outcome was in-hospital mortality.

A total of 1479 consecutive injured children were eligible for inclusion. One hundred ninety-four patients were excluded for missing IVF data, aged ≥16y, having primary burnusting for injury severity and initial hemodynamics. These results encourage further investigation into initial resuscitation strategies for injured children.

Previous studies on pediatric thyroid surgical complications suggest that high-volume centers achieve improved outcomes. We hypothesize that initial outcomes from a nascent pediatric surgical practice may be comparable to higher volume centers. Furthermore, we determine whether a low-volume center can safely transition to an intermediate or high-volume center.

A retrospective chart review was performed for all pediatric patients undergoing thyroid surgery at a single institution from 2014 to 2020. Surgeries were performed by two pediatric otolaryngologists. All patients were managed postoperatively by a multidisciplinary team of physicians that included pediatric otolaryngologists and endocrinologists. Data collection focused on patient demographics and postoperative complications, including rates of recurrent laryngeal nerve injury and permanent hypoparathyroidism.

From 2014 to 2020, a total of 31 patients underwent thyroid surgery at our pediatric thyroid surgery center, 9 of whom underwent neck dissection. The mean age of our cohort was 14.4±3.9 years (range 8 months-20 years). Postoperative pathology results revealed that 15 patients (46.9%) were diagnosed with PTC, 6 (18.8%) with follicular adenoma, and 4 (15.6%) with benign thyroid tissue. One (2.0%) patient had permanent unilateral recurrent laryngeal nerve paralysis and one patient experienced permanent hypoparathyroidism (2.7%).

Our initial low complication rate as a nascent pediatric thyroid surgery center suggests that favorable outcomes can be achieved at lower volume surgery centers. In order to increase patient access to high-volume pediatric thyroid surgery centers, new centers must start with lower volumes before ultimately becoming high-volume centers. Our study shows that this can be safely achieved.
