ctim susceptible to disease of the skin, bones, and also cancer of liver, kidney, gall bladder and the intestines. It is necessary to adopt highly successful technology to treat As contaminated water into the acceptable limit for human consumption. Universally accepted solutions are not developed/available even after the lapse of almost forty years since slow As poisoning identification in tens of millions of people especially in Bengal delta. The issue poses scientific, technical, health and societal problems even today.Thioredoxin peroxidase (TPx) plays an important role in protecting parasites against oxidative damage. However, studies on the role of TPxs in Echinococcus multilocularis are limited. In this study, one tpx gene of E. multilocularis, named as emtpx-1, was identified. EmTPx-1 shares two positionally conserved cysteine residues (Cys48 and Cys169) with orthologs from other platyhelminths. EmTPx-1 is highly expressed in the germinal layer and present in exosome-like vesicles secreted by E. multilocularis metacestodes. EmTPx-1 displays peroxidase activity, which removes hydrogen peroxide in the presence of dithiothreitol. Furthermore, EmTPx-1 could protect DNA from oxidative damages, and EmTPx-1-expressing E. coli cells had an enhanced resistance to oxidative stress. In addition, EmTPx-1 enhanced the expression of arg1, ym1, and il-10, but suppressed inos, tnf-α, and il-1β expression in LPS-stimulated macrophages. Our data suggest a critical role for EmTPx-1 in oxidative stresses and M2 macrophage polarization.

Developing NTCP-models for cardiac complications after breast cancer (BC) radiotherapy requires cardiac dose-volume parameters for many patients. These can be obtained by using multi-atlas based automatic segmentation (MABAS) of cardiac structures in planning CT scans. We investigated the relevance of separate multi-atlases for deep inspiration breath hold (DIBH) and free breathing (FB) CT scans.

BC patients scanned in DIBH (n=10) and in FB (n=20) were selected to create separate multi-atlases consisting of expert panel delineations of the whole heart, atria and ventricles. The accuracy of atlas-generated contours was validated with expert delineations in independent datasets (n=10 for DIBH and FB) and reported as Dice coefficients, contour distances and dose-volume differences in relation to interobserver variability of manual contours. Dependency of MABAS contouring accuracy on breathing technique was assessed by validation of a FB atlas in DIBH patients and vice versa (cross-validation).

For all structures the FB and DIBH atlases resulted in Dice coefficients with their respective reference contours≥0.8 and average contour distances≤2mm smaller than slice thickness of (CTs). No significant differences were found for dose-volume parameters in volumes receiving relevant dose levels (WH, LV and RV). Accuracy of the DIBH atlas was at least similar to, and for the ventricles better than, the interobserver variation in manual delineation. Cross-validation between breathing techniques showed a reduced MABAS performance.

Multi-atlas accuracy was at least similar to interobserver delineation variation. Separate atlases for scans made in DIBH and FB could benefit atlas performance because accuracy depends on breathing technique.

Stereotactic ablative radiotherapy (SABR) can achieve good local control for metastatic adrenal lesions. Magnetic resonance (MR)-guidance with daily on-table plan adaptation can augment the delivery of SABR with greater dose certainty. The goal of this study was to quantify the potential clinical benefit MR-guided daily-adaptive adrenal SABR using the normal tissue complication probability (NTCP) framework.

Patients treated with adrenal MR-guided SABR at a single institution were retrospectively reviewed. Lyman-Kutcher-Burman NTCP models were used to calculate the NTCP of upper abdominal organs-at-risk (OARs) at simulation and both before and after daily on-table plan adaptation. Differences in OAR NTCPs were assessed using signed-rank tests. Potential predictors of the benefits of adaptation were assessed by linear regression.

Fifty-two adrenal MR-guided SABR courses were analyzed. The baseline simulation plan underestimated the absolute stomach NTCP by 10.0% on average (95% confidence interval 4.7-15.edicted NTCP.

This randomized controlled phase II study investigated the efficacy, safety and underlying mechanism of maxillofacial and oral massage (MOM) in nasopharyngeal carcinoma (NPC) patients receiving intensity-modulated radiotherapy.

A total of 158 NPC patients were randomly assigned 11 to routine oral care and medication (the control group) or that with additional MOM (the treatment group). The primary endpoint was the incidence of severe radiotherapy-induced oral mucositis (SRTOM). In addition, the time of initiation and duration of RTOM and SRTOM, adverse events, dynamic changes of lipid metabolites in peripheral blood were analyzed.

Seventy-six patients in the treatment group and seventy-nine in the control group completed the trial. The incidence of SRTOM in the treatment group was lower than the control (26.3% vs. 46.8%, P=0.008). The median initiation time to RTOM and SRTOM was significantly longer in the treatment group than the control (RTOM12 vs 10days, hazard ratio [HR] 0.52, P<0.001; SRTOM 28.5 vs 19days, HR 0.5579, P=0.002). While the median duration time of RTOM and SRTOM in the treatment group was shorter (RTOM 20.7 vs 24.7days, P=0.001; SRTOM 8.05 vs 13.08days, P<0.001). Only 1.3% of patients obtained grade 3 or higher adverse events during MOM. The anti-inflammatory lipids increased significantly after MOM, especially with 10.6Gy or higher.

MOM significantly attenuated the incidence of SRTOM in NPC patients. The adverse events of MOM were slight and tolerant. MOM enhanced anti-inflammatory lipid metabolites, which might be an underlying mechanism.

Cone beam CT (CBCT) is used in paediatric image-guided radiotherapy (IGRT) for patient setup and internal anatomy assessment. Adult CBCT protocols lead to excessive doses in children, increasing the risk of radiation-induced malignancies. Reducing imaging dose increases quantum noise, degrading image quality. Patient CBCTs also include 'anatomical noise' (e.g. motion artefacts), further degrading quality. We determine noise contributions in paediatric CBCT, recommending practical imaging protocols and thresholds above which increasing dose yields no improvement in image quality.

Sixty CBCTs including the thorax or abdomen/pelvis from 7 paediatric patients (aged 6-13years) were acquired at a range of doses and used to simulate lower dose scans, totalling 192 scans (0.5-12.8mGy). Noise measured in corresponding regions of each patient and a 10-year-old phantom were compared, modelling total (including anatomical) noise, and quantum noise contributions as a function of dose. Contrast-to-noise ratio (CNR) wasise.IFN-γ is one of the key cytokines involved in Th1 immune responses. It is produced mainly by T cells and NK cells, which drive both innate and adaptive responses to promote protection against infections. IFN-γ orthologues have been discovered to be functionally conserved in fish, suggesting that type I immunity is present in early vertebrates. However, few studies have looked at IFN-γ protein expression in fish and its role in cell mediated immunity due to a lack of relevant tools. In this study, four monoclonal antibodies (mAbs) V27, N2, VAB3 and V91 raised against short salmonid IFN-γ peptides were developed and characterised to monitor IFN-γ expression. The results show that the IFN-γ mAbs specifically react to their peptide immunogens, recognise E. coli produced recombinant IFN-γ protein and rainbow trout IFN-γ produced in transfected HEK 293 cells. The mAb VAB3 was used further, to detect IFN-γ at the cellular level after in vitro and in vivo stimulation. In flow cytometry, a basal level of 3-5% IFN-γ seiated immunity in fish.This study aims to assess and determine the oral-administration of probiotic, Lactobacillus pentosus BD6 on growth performance, immunity and disease resistance of white shrimp, Litopenaeus vannamei. Lac. pentosus BD6 effectively inhibited the growth of aquatic pathogens, which was used in the test. Shrimp were fed with the control diet (without probiotic supplement) for 60 days and the probiotic-containing diets at 107, 108, 109, and 1010 cfu kg-1, respectively. 3-Deazaadenosine mw Shrimp fed with the diet containing probiotic at the doses of 109-10 cfu kg-1 showed significant increase in growth performance as well as feed efficiency than that of the control. After a challenge test with Vibrio alginolyticus, shrimp fed with a probiotic diet at a dose of 1010 cfu kg-1 showed a significantly lower mortality as compared to the control and that of shrimp fed the diet containing probiotic at the levels up to 107-8 cfu kg-1. In addition, a therapeutic potential of Lac. pentosus BD6 was discovered because the cumulative mortalities of group, compared to the control group. It was concluded that Lac. pentosus BD6 has great antibacterial ability against a wide range of pathogens and has therapeutic potential to reduce the mortality of shrimp infected with V. parahaemolyticus. Additionally, dietary Lac. pentosus BD6 at the level of 1010 cfu kg-1 was recommended to improve growth performance, immunity and disease resistance of shrimp against V. alginolyticus.Calcification is common in atherosclerotic plaque and can induce vulnerability, which further leads to myocardial infarction, plaque rupture and stroke. The mechanisms of atherosclerotic calcification are poorly characterized. Interleukin enhancer binding factor 3 (ILF3) has been identified as a novel factor affecting dyslipidemia and stroke subtypes. However, the precise role of ILF3 in atherosclerotic calcification remains unclear. In this study, we used smooth muscle-conditional ILF3 knockout (ILF3SM-KO) and transgenic mice (ILF3SM-Tg) and macrophage-conditional ILF3 knockout (ILF3M-KO) and transgenic (ILF3M-Tg) mice respectively. Here we showed that ILF3 expression is increased in calcified human aortic vascular smooth muscle cells (HAVSMCs) and calcified atherosclerotic plaque in humans and mice. We then found that hyperlipidemia increases ILF3 expression and exacerbates calcification of VSMCs and macrophages by regulating bone morphogenetic protein 2 (BMP2) and signal transducer and activator of transcription 1 (STAT1) transcription. We further explored the molecular mechanisms of ILF3 in atherosclerotic calcification and revealed that ILF3 acts on the promoter regions of BMP2 and STAT1 and mediates BMP2 upregulation and STAT1 downregulation, which promotes atherosclerotic calcification. Our results demonstrate the effect of ILF3 in atherosclerotic calcification. Inhibition of ILF3 may be a useful therapy for preventing and even reversing atherosclerotic calcification.
