Abstract
Lutetium-177 ( 177 Lu)-DOTATATE is an effective systemic therapy for metastatic somatostatin receptor positive neuroendocrine tumors (NETs). Here we report our experience with the use of pre-therapy 68 Ga-DOTATATE PET as prognostic marker for short-term clinical outcomes of 177 Lu-DOTATATE therapy in patients with advanced NETs. Materials and methods: We retrospectively reviewed patients who received at least one dose of 177 Lu-DOTATATE between Dec. 2016 and July 2019 at our institution. 50 patients (63.6 ± 10.0 years) with advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs) who had pre-therapy 68 Ga-DOTATATE PET were included in the analysis. 68 Ga-DOTATATE avid tumor volumes were determined automatically using an SUV thresholding approach. Total and extrahepatic 68 Ga-DOTATATE avid tumor volumes were measured and dichotomized into large and small tumor volume groups. Association with progression free survival (PFS) and overall survival (OS) were determined at median follow up of 32 months by Kaplan-Meier survival analysis with Log-Rank test. Results: During follow up, 38 patients (76%) had disease progression and 15 patients (30%) died. Kaplan-Meier analysis of PFS in GEP-NETs patients showed that smaller extrahepatic 68 Ga-DOTATATE avid tumor volume (<140 mL) is associated with significantly longer PFS (Median PFS 29.0 ± 6.7 months vs 9.0 ± 1.7 months, P = 0.0001). This trend in PFS is less prominent when total 68 Ga-DOTATATE avid tumor volume is analyzed. Similarly, Kaplan-Meier analysis of OS found that GEP-NETs patients with smaller extrahepatic 68 Ga-DOTATATE avid tumor volume (<150 mL) is associated with significantly longer OS (Median OS not reached vs 44.0 ± 12.3 months, P = 0.002). This association with OS is not statistically significant when total 68 Ga-DOTATATE avid tumor volume is analyzed. When 68 Ga-DOTATATE avid hepatic tumor volume is grouped into low (<500 mL), medium (500-1000mL) and large (> 1000 mL) tumor volumes, no statistically significant difference in PFS is observed, P = 0.19. The accuracy of extrahepatic 68 Ga-DOTATATE avid tumor volume as prognostic marker for PFS and OS at 32 months are moderate at 58% and 72%. Conclusions: Smaller extrahepatic 68 Ga-DOTATATE avid tumor volumes are associated with longer PFS and OS following 177 Lu-DOTATATE treatment in patients with advanced GEP-NETs. The accuracy of extrahepatic 68 Ga-DOTATATE avid tumor volume as prognostic marker for PFS and OS at 32 months are moderate, which may limit its clinical application.

Abstract
Accumulating evidence indicates that dysregulation of human microRNAs could serve as diagnostic and prognostic biomarkers in nasopharyngeal carcinoma (NPC). In the present study, we found that up-regulation of miR-182-5p was significantly associated with tumor development and poor prognosis in patients with NPC. Functional study demonstrated that miR-182-5p overexpression enhanced, whereas suppression of miR-182-5p impeded NPC cell proliferation, migration, tumorigenesis and metastasis. Mechanistically, miR-182-5p interacted with ZFP36 ring finger protein like 1 (ZFP36L1) at two sites in its 3’ un-translated region (UTR) and repressed ZFP36L1 expression in NPC. Consistently, an inverse correlation was observed between the expression levels of miR-182-5p and ZFP36L1 using clinical NPC primary tissues, and down-regulation of ZFP36L1 in NPC predicts poor survival. Furthermore, overexpression of miR-182-5p in NPC was attributable to the transcriptional activation effect induced by hypoxia-inducible factor 1α (HIF-1α). Taken together, our data suggest that miR-182-5p facilitates NPC development and progression through its ability to down-regulate ZFP36L1 expression, and that the HIF-1α/miR-182-5p/ZFP36L1 axis may serve as a novel therapeutic target in the management of NPC.

Abstract
Khetri Copper Belt, Rajasthan is anthropogenically active and geologically belongs to the Delhi supergroup. To study the active geochemical processes controlling the elemental mobility, representative groundwater samples were analysed for heavy metals and radionuclide (U). A maximum U concentration (average 87 µgL− 1) is observed in the quartzite mine zone whereas minimum (average 13 µgL− 1) is found to be in the copper mine zone samples. Despite the presence of Jaspura and Gothra granitoid in the copper mine zone, the abundance of U is low suggesting the scavenging of U by sulphides or iron oxides. Additionally, at the confluence of two geological groups, Fe concentration is found high with a low concentration of U which further confirms scavenging of U. In the region, aquifers are shallow which supports the weathering of minerals. Thus, a high concentration of U in groundwater is attributed to mineral dissolution, faults or fractures. It is evident from the results that in the absence of iron-bearing sulphides, U concentration in groundwater would be very high compared to the current concentration. It also indicates low concentration of U in the copper mine zone, area is covered with abundant quantity of Fe sulphide rich waste. The present study recommends further research to understand the feasibility of mining waste for the removal of U contamination from groundwater.

Abstract
Bio-inspired nanoparticle synthesis has attracted substantial interest among the scientific society owing to its eco-friendly and non-toxic nature. In the present study, Silver nanoparticles (AgNPs) were synthesized using high altitude squamulose lichen – Cladonia subradiata and characterized using different techniques. The antioxidant and anticandida activity of AgNPs were evaluated using multiple in-vitro assays. In-silico molecular docking analysis and in-vitro cytotoxic assay was performed to determine the anti-cancer potential of synthesized AgNPs. The results of the spectroscopic studies revealed the successful synthesis of AgNPs and the presence of different functional groups suggesting the involvement of phytocompounds in the reduction and capping of AgNPs. The average size of the AgNPs was 20 nm and predominantly spherical in shape. AgNPs demonstrated excellent DPPH free radicals scavenging activity with an IC50 value of 7.51 ± 0.4 µg/mL. C.albicans was identified as the most susceptible strain from the anticandida studies. Usnic acid and Pulvinic acid exhibited low binding energies and showed excellent inhibition interaction with EGFR lung cancer protein. The in-vitro cytotoxic results were impressive with an IC50 value of 28.75 µg/mL for A549 lung cancer cells treated with AgNPs. Thus, the study demonstrates the effective and non-toxic synthesis of AgNPs using a less explored lichen extract as a promising anticandida and anticancer agent in the field of nano-medicine.

Published: April 2021

Abstract
Background High-intensity interval training (HIIT) has been shown to confer cognitive benefits in healthy adults, via a mechanism purportedly driven by the exercise metabolite lactate. However, our understanding of the exercise parameters (e.g., work interval durations, session volumes, work-to-rest ratio) that evoke a peak blood lactate response in healthy adults is limited. Moreover, evidence relating HIIT-induced blood lactate and cognitive performance has yet to be reviewed and analyzed. The primary objective of this systematic review is to use network meta-analyses to compare the relative impact of different HIIT work interval durations, session volumes, and work-to-rest ratios on post-exercise blood lactate response in healthy adults. The secondary objective is to determine the relationship between HIIT induced blood lactate and acute post-HIIT cognitive performance.Methods A systematic review is being conducted to identify studies measuring blood lactate response following one session of HIIT in healthy adults. The search was carried out in (1) MEDLINE, (2) EMBASE, (3) Cochrane Central Register of Controlled Trials, (4) Sport Discus, and (5) Cumulative Index to Nursing and Allied Health Literature Plus with Full Text (CINAHL+). After abstract and full-text screening, two reviewers will independently extract data on key outcomes variables and complete risk of bias assessment using the Cochrane risk of Bias Tool and the Risk of Bias in Non-Randomized Studies of Interventions tool. Network meta-analyses will be used to generate estimates of the comparative effectiveness of blood lactate on cognitive outcomes using corresponding rankings for each work interval, session volume, and work-to-rest category. Where applicable, meta-regressions analyses will be performed to test the relationship between changes in blood lactate and changes in cognitive performance. Analyses will be conducted using MetaInsight Software Discussion This study will provide evidence on how to structure a HIIT protocol to elicit peak blood lactate response in healthy adults, and will increase our understanding of the relationship between HIIT induced blood lactate response and associated cognitive benefits.Systematic review registration: This review has been registered in the PROSPERO database (CRD42020204400).

Abstract
Background: Coccidiosis is one of the major parasitic diseases in the commercial broiler industry. Probiotics can protect poultry against Eimeria infection. However, the mechanisms are not fully known. Therefore, Lactobacillus plantarum P8 (P8) was used to investigate its anti-coccidial property and mechanism.Methods: Five hundred broilers were allocated to five treatments: control diet (NC), control diet + Eimeria infection (IC), control diet containing 1 × 107 cfu/g P8 + Eimeria infection (P8L), control diet containing 1 × 108 cfu/g P8 + Eimeria infection (P8H), and control diet + Eimeria infection + Diclazuril (DIC). At day 14, all treatments except NC were inoculated with sporulated oocysts. Results: Eimeria infection increased the mortality and oocysts shedding, and declined the growth performance as well as the intestinal barrier in Eimeria-treated broilers. On the contrary, dietary supplementation of low level P8, high level P8 and DIC decreased the mortality and oocysts shedding, but improved the growth performance and intestinal barrier. The impaired intestinal morphology in the IC group was also improved by P8H and DIC treatments. Besides, the elevated oxidative stress and pro-inflammation in Eimeria-infected broilers were reduced by P8L, P8H and DIC treatments. Metagenomic analysis indicated P8 altered the structure of the gut microbiota, and the alteration was more obvious at day 21 than day 42. Notably, IC also increased the abundances of Eimeriidae, Eimeria and Eimeria tenella at day 21, while P8L and DIC decreased the abundances. Correlation analysis revealed that bacteria in Eimeria-treated broilers positively correlated with the intestinal permeability, oxidative stress and inflammation, while bacteria in broilers receiving P8L and DIC negatively correlated with the aforementioned pathological indices. Functional prediction demonstrated that the metagenomes of Eimeria-infected broilers were involved in several diseases. But the metagenomes of P8L-treated broilers were involved in energy metabolism and replication repair. Conclusions: Dietary P8 supplementation inhibited oocyst shedding and improved the growth performance as well as the intestinal health of broilers infected with Eimeria, which was closely related to the regulation of gut microbiota. Moreover, the effects of P8 may be more effective in the early infection of coccidia.

Abstract
Sphaeralcea angustifolia (Cav) G. Don is used in traditional Mexican medicine to treat inflammations and gastric disease. Its anti-inflammatory and immunomodulatory activities in mice and rats acute and chronic models have been attributed mainly to scopoletin. Scopoletin reduced joint inflammation, the number of new vessels, production of endogenous angiogenic inducers, and reversed the histopathological alterations in rat adjuvant-induced arthritis. Tomentin and sphaeralcic acid from S. angustifolia cells in suspension proved anti-inflammatory and immunomodulatory activities in mice kaolin/λ-carrageenan-induced arthritis. Transformed roots of S. angustifolia have been proposed as active compounds producers. A high transformation frequency mediated by Agrobacterium rhizogenes ATCC15834/pTDT was obtained from nodal segments (59.5 ± 10.5%, 145 hairy root lines) and leaves (40.0 ± 25, 52 hairy root lines) of 2-month-old plantlets. Among seven lines selected according to their phenotypic characteristics and growth index, the SaTR N7.2 line presented the highest sphaeralcic acid production (17.6 ± 1.72 mg/g DW); this production was 440-fold superior to that reported in S. angustifolia wild plants, and in comparison to cells in the suspension of S. angustifolia in MS medium with nitrate restriction this was 263-fold higher when cultured in flasks and 5-fold higher in a stirred-tank type bioreactor. The SaTR N7.2, SaTR N5.1, SaTR N7.1, and SaTR N15.1 lines excreted sphaeralcic acid into the culture medium at similar levels. Genetic transformation of hairy roots was confirmed by amplifying a 490 bp fragment of the rolC gene. S. angustifolia hairy root cultures producers of scopoletin and sphaeralcic acid can be stressed by nitrate reduction and/or copper increased to stimulate scopoletin and sphaeralcic acid production.

Abstract
ColorColorectal cancer is one of the most common cancer worldwide. Recently, tumor microenvironment (TME), especially its remoulding , is thought to control the colorectal cancer genesis and progression. In this study, we use ESTIMATEscore to make out the proportion of immune and stromal components in colorectal adenocarcinoma (CRA) samples from The Cancer Genome Atlas (TCGA) database. The differentially expressed genes (DEGs) were found by COX regression analysis and protein-protein interaction (PPI) network, among which TGFβ1 was supposed to be a prognosis factor and tumor environment indicator. Continuous analysis showed that TGFβ1 expression is positively correlated with lymph node metastasis (N stage) but negatively correlated with survival. Gene Set Enrichment Analysis (GSEA) revealed that the genes of the high-expression TGFβ1 group were mainly enriched in immune-related activities. Cluster analysis divided the samples into 2 subgroups. 24 HLA-related genes and 8 immune checkpoint genes were found upregulated in the high immunity group as well as TGFβ1, which suggests the possibility of novel therapies targeting immune checkpoints combined with TGFβ1. Tumor-infiltrating immune cell (TIC) profile of CRA patients was described by CIBERSORT analysis. Further analysis showed that the infiltration of Tregs and Neutrophils were positively correlated with TGFβ1 high expression. Then 3 TGFβ1-related genes were picked out to construct a prognostic model, which matches the survival data well.
Optimization of Optical Filters based on Integrated Coupled Sagnac Loop Reflectors
Authors: Moss David 
Published: April 2021

Abstract
We theoretically investigate integrated photonic resonators formed by two mutually coupled Sagnac loop reflectors (MC-SLRs). Mode interference in the MC-SLR resonators is tailored to achieve versatile filter shapes with high performance, which enable flexible spectral engineering for diverse applications. By adjusting the reflectivity of the Sagnac loop reflectors (SLRs) as well as the coupling strength between different SLRs, we achieve optical analogues of Fano resonance with ultrahigh spectral slope rates, wavelength interleaving / non-blocking switching functions with significantly enhanced filtering flatness, and compact bandpass filters with improved roll-off. In our designs the requirements for practical applications are considered, together with detailed analyses of the impact of structural parameters and fabrication tolerances. These results highlight the strong potential of MC-SLR resonators as advanced multi-functional integrated photonic filters for flexible spectral engineering in optical communications systems.

Abstract
Energy system modelling can be used to assess the implications of different scenarios and support improved policymaking. However, access to data is often a barrier to starting energy system modelling in developing countries, thereby causing delays. Therefore, this article provides data that can be used to create a simple zero order energy system model for Nigeria, which can act as a starting point for further model development and scenario analysis. The data are collected entirely from publicly available and accessible sources, including the websites and databases of international organizations, journal articles, and existing modelling studies. This means that the dataset can be easily updated based on the latest available information or more detailed and accurate local data. These data were also used to calibrate a simple energy system model using the Open Source Energy Modelling System (OSeMOSYS) and two stylized scenarios (Fossil Future and Least Cost) for 2020–2050. The assumptions used and results of these scenarios are presented in the appendix as an illustrative example of what can be done with these data. This simple model can be adapted and further developed by in-country analysts and academics, providing a platform for future work.

Tariff structuring in water and sanitation: public profiting arrangements on universalization initiatives
Authors: Motta-Veiga Marcelo 
Published: April 2021

Abstract
Water and sanitation service access is a global problem, impacting disproportionally poor communities of low-income countries. Failed universalization initiatives highlighted historical negligence, social inequality, and bad governance. Infrastructure developments require large investments, which most local governments cannot afford. Alternative funding might come from private investors through cost-effective project finance arrangements. Public services should be sustainable, conciliating users' willingness to pay with providers' willingness to supply. Governments have implemented profit-driven strategies over taxing outsourced public services to increase budget inflow. Inefficient tax schemes on essential public services have damaged universalization initiatives in developing countries. These negative taxing practices have damaged tariff structure, service sustainability, and project attractiveness. The public sector should not profit from unsustainable outsourced services that are required but they cannot supply. Water and sanitation expansions on low-income communities in developing countries should not take place as tariff-free schemes, but within a tax-exempt policy.
