The aim of this study was to investigate the response of THP-1 monocyte-derived macrophages following exposure to titanium dioxide nanoparticles (TiO
NPs) and microparticles (TiO
MPs) in an in vitro system.

THP-1 monocytes were maintained in RPMI medium and transformed into M0 macrophages using Phorbol 12-myristate 13-acetate (PMA). TiO
particle size characterization was performed using scanning electron microscopy (SEM) and dynamic light scattering (DLS) technology. A viability study using an XTT assay was performed by treating THP-1-derived macrophages with TiO
NPs (<100 nm) and TiO
MPs (<5 μm) at concentrations ranging from 100, 50, 25, 12.5, 6.25 and 3.125 μg/mL. Macrophages were then treated with three different concentrations of NPs and MPs (5, 20 or 100 μg/mL) for 24 h, and ROS production and TiO
particle cellular uptake were measured using ROS assays and flow cytometry, respectively.

There was no significant change in the viability of THP-1 monocytes after treatment with TiO
NPs and MPs. The uptake of both particles was confirmed and showed an increase in ROS generation, and the MPs produced more ROS than NPs. The increase in ROS generation with NPs was concentration-dependent.

Uptake of TiO
NPs and MPs in macrophages at subcytotoxic levels generate ROS in a size- and dose-dependent manner.

To evaluate the cost-effectiveness of screening for depression in patients with acute coronary syndrome (ACS) and no history of depression.

Cost-effectiveness analysis of a randomized trial enrolling 1500 patients with ACS between 2013 and 2017. Patients were randomized to no screening, screening and notifying the primary care provider (PCP), and screening, notifying the PCP, and providing enhanced depression treatment. Outcomes measured were Healthcare utilization, costs, and incremental cost-effectiveness ratios.

7.1% of patients screened positive for depressive symptoms. There was no significant difference in usage of mental health services, cardiovascular tests and procedures, and medications. Mean total costs in No Screen group ($7440), in Screen, Notify, and Treat group ($6745), and in Screen and Notify group ($6204). The difference was only significant in the Screen and Notify group versus the No Screen group (-$1236, 95% confidence interval -$2388 to -$96). Because mean QALYs were higher (+0.003 QALY in Screen and Notify; +0.004 QALYs in Screen, Notify, and Treat) and mean total costs were lower in both intervention groups, these interventions were cost-effective. There was substantial uncertainty because confidence intervals around cost differences were wide and QALY effects were small.

Depression screening strategies for patients with ACS may be modestly cost-effective.

Nevertheless, critical reviews on strategic control and effective remediation of MPs in the aqueous phase are still lacking. In this work, we summarise the origins and types of MPs, and then introduce the methodologies for extraction, identification and quantification. More importantly, we for the first time provide a comprehensive overview of the recent advances in the emerging MPs removal and transformation technologies. Except for biodegradation, this review presents new applications of advanced oxidation processes (AOPs) for MPs degradation and utilisation, including photocatalysis, photoreforming and Fenton-like reactions. Physical or catalytic thermal treatment can transform plastics into value-added nanocarbons or hydrocarbons. These transformation technologies demonstrate great potentials in dealing with MPs. The review will guide researchers to further explore the feasible approaches and develop new strategies for advanced control and remediation of MPs in the future.Forward osmosis-membrane distillation (FO-MD) hybrids were recently found suitable for produced water treatment. Exclusion of synthetic chemical draw solutions, typically used for FO, can reduce FO-MD operational costs and ease its onsite application. This study experimentally validates a novel concept for the simultaneous treatment of different produced water streams available at the same industrial site using an FO-MD hybrid system. The water oil separator outlet (WO) stream was selected as FO draw solution and it generated average fluxes ranging between 8.30 LMH and 26.78 LMH with four different feed streams. FO fluxes were found to be governed by the complex composition of the feed streams. On the other hand, with WO stream as MD feed, an average flux of 14.41 LMH was achieved. Calcium ions were found as a main reason for MD flux decline in the form of CaSO4 scaling and stimulating the interaction between the membrane and humic acid molecules to form scale layer causing reduction in heat transfer and decline in MD flux (6%). Emulsified oil solution was responsible for partial pore clogging resulting in further 2% flux decline. Ethylenediaminetetraaceticacid (EDTA) was able to mask a portion of calcium ions and resulted in a complete recovery of the original MD flux. Under hybrid FO-MD experiments MD fluxes between 5.62 LMH and 11.12 LMH were achieved. Therefore, the novel concept is validated to produce fairly stable FO and MD fluxes, with few streams, without severe fouling and producing excellent product water quality.Urine comprises only a small (~1%) volumetric fraction of municipal wastewater, but represents a dominant source of pharmaceuticals, many of which may pass through conventional wastewater treatment and pose risks to aquatic ecosystems. Point-source treatment of source-separated urine presents a unique opportunity to degrade pharmaceuticals before dilution with wastewater, and electrochemical advanced oxidation processes are one increasingly investigated option. However, they often lead to the formation of oxidation byproducts including chlorate, perchlorate at very high concentrations. Here, we show that the high urea content of fresh human urine suppresses the formation of oxychlorides by inhibiting formation of HOCl/OCl‒ during electrolysis, while still enabling pharmaceutical degradation due to the slow rate of urea oxidation by •OH. This results in improved performance compared to equivalent treatment of hydrolyzed aged urine. This electrochemical oxidation scheme is shown to degrade the model contaminants cyclophosphamide and sulfamethoxazole with surface-area-to-volume-normalized pseudo-first-order rate constants greater than 0.08 cm/min in authentic fresh human urine. It results in ~100 × decrease in pharmaceutical concentrations in 2 h while generating ~1000 × lower oxychloride byproduct concentrations in synthetic fresh urine than synthetic hydrolyzed aged urine matrixes. Importantly, this proof-of-principle shows that simple and safe electrochemical methods can be used for point-source-remediation of pharmaceuticals in fresh human urine (before storage and hydrolysis), without formation of significant oxychloride byproducts.Bovine viral diarrhea (BVD) is a disease that affects cattle and other ruminants worldwide and causes considerable economic losses. A cross-sectional study was carried out between December 2017 and July 2018 with the aim to estimate the prevalence of Bovine Viral Diarrhea virus (BVDV) antibodies and to identify potential risk factors associated with the occurrence of the disease in dairy cattle in peri-urban areas of Gondar city, Northwest Ethiopia. A total of 339 serum samples obtained from randomly selected dairy cattle aged 6 months and older were assayed using a BVDV antibody competitive-Enzyme Linked Immunosorbent Assay (c-ELISA) kit. Descriptive statistics were used to estimate antibody prevalence of BVDV at animal and herd-level and logistic regression was used to identify potential risk factors. The study findings showed that the animal-level antibody prevalence of BVDV in the study area was 26.84 % (95 % CI 22.1 %-31.6 %) and the herd-level seroprevalence was 68.3 % (95 % CI 56.2 %-80.4 %). Logistic regression model demonstrated that age >2 years (OR = 4.75, 95 % CI 2.20-10.26), herd size >11 (OR = 7.28, 95 % CI 2.50-21.22), and poor farm hygiene (OR = 3.69, 95 % CI 1.94-7.02), are potential risk factors associated with BVDV infection (P less then 0.05). However, sex, faecal consistency and housing system were not associated with BVDV serostatus. The animal- and herd-level seroprevalence reports in Northwest Ethiopia can serve as a baseline finding for future BVD epidemiological investigations and to inform future control programs in the study region.The bacterium Coxiella burnetii (C. burnetii) can infect a wide range of animals, most notably ruminants where it causes mainly asymptomatic infections and, when clinical, it is associated with reproductive disorders such as abortion. It is also the etiological agent of Q fever in humans, a zoonosis of increasingly important public health concern. A cross-sectional study was performed to estimate the apparent prevalence and spatial distribution of C. burnetii positivity in dairy cattle and small ruminant herds of two regions of Québec, Canada, and identify potential risk factors associated with positivity at animal and herd levels. In dairy cattle herds, individual fecal samples and repeated bulk tank milk samples (BTM) were collected. selleck chemicals llc In small ruminant herds, serum and feces were sampled in individual animals. ELISA analyses were performed on serum and BTM samples. Real-time quantitative PCR (qPCR) was done on fecal and BTM samples. An animal was considered C. burnetii-positive when at least one sample was r with a dog on the farm had greater odds of C. burnetii positivity. Our study shows that the infection is frequent on dairy cattle and small ruminant herds from the two studied regions and that some farm and animal characteristics might influence the transmission dynamics of the C. burnetii infection.The output of an affinity selection screening results in a huge amount of valuable data that, after conducting the appropriate analysis, lead to the correct identification of the compounds enriched in the target of interest. The approach chosen to perform these analyses has become a key step in the development of a successful DNA Encoded Library platform. In this paper, we describe the combination of High Performance Liquid Chromatography purification during the library production with the Next Generation Sequencing analysis of the libraries to assess the yield of the chemical reactions prior to the affinity selection. This process allows us, apart from achieving higher quality libraries, to enable a normalization analysis of the affinity selection output, thus minimizing the bias induced by the chemical yield of each reaction as a misleading factor within the analysis and subsequent compound short-listing for off-DNA synthesis.
