Food traceability has an important role in maintaining the sustainability of the food supply chain. Every player in a food supply chain must be able to create an internal and external traceability so that the chain traceability can be formed. However, building a suitable food traceability system is not an easy task. The development of a food traceability system has been identified as a complex problem due to the difficulty of accommodating the varied characteristics of each stage in the food supply chain and the interdependence between stages in the food supply chain. Therefore, to solve these complex problems a multimethodology approach is proposed. The multimethodology approach is believed to be able to solve complex multidimensional problems. This article describes a framework for multimethodology in the development of a food traceability system that involves the integration of the Decision Making Trial and Evaluation Laboratory and Interpretive Structural Modeling (DEMATEL-ISM) and System Dynamics (SD). The vegetable oil industry which manages its products in bulk is an interesting case study for the development of a food traceability system because the upstream is in the commodity focused chain and the downstream is in the consumer driven value chain. Ultimately, the multi-methodological framework proved effective in answering the research question of "How to develop a suitable traceability system for the bulk vegetable oil industry?"

This study aims to investigate the mixing time of the side-entry mixer tank and the influence of the propeller's rotational speed on mixing time by the Computational Fluid Dynamic (CFD) method. The tank's model is a flat-bottom cylinder tank whose diameter is 40 cm with a 6 cm propeller contains three blades. The tracer, HCL 37%, was injected on the water's surface while the propeller's rotation speed is varied 100 rpm, 200 rpm, 300 rpm, and 400 rpm. The simulation process is examined using CFD FLUENT 17.1, with a turbulence model is k-ɛ RNG. Its conditions are single-phase then proceeded using species transport. Furthermore, the monitoring point's simulation is identical to the experimental data monitoring probe, which is used to inspect the mass fraction at each point. After all, this simulation contains three processes: pre-processing, solving, and post-processing. as a result, the propeller's higher rotational speed makes the mixing time shorter in the CFD method, which has a good agreement with the experimental method. Moreover, this study also examines the impact of the grid's type and the geometric size for the mixing process in the side-entry mixer tank.

Backgrouds: Stroke is the second most prevalent cause of death and the first cause of longterm disability worldwide. Inhibition of miR-155 was found playing a protective role in ischemic stroke, one possible mechanism was regulating Ras-homolog enriched in brain (Rheb)/mammalian target of rapamycin (mTOR) pathway. For possible specific intervention strategy, further exploring the expression characteristics of miR-155 and mRNAs of the Rheb/mTOR pathway in ischemic stroke is neccesary. Results: Our results demonstrated that the infarction volume decreased with the prolongation of the reperfusion in the MCAO/R model rats (P < 0.05). Meanwhile, the miR155 expression obviously increased in both the ischemic core and the ischemic penumbra (IP) area of the model rats, but this trend weakened as the reperfusion time increased. Besides, the expression of mRNAs of Rheb, mTOR, S6kb1, and 4Ebp1 seemed to increase in both the ischemic core and the IP area of the model rats.Interestingly, the mRNA level of S6kb1 obviously increased of all model groups in both the ischemic core and the IP area (P < 0.05),while the mRNA levels of Rheb, mTOR, and 4Ebp1 increased in the first 24 h and rapidly decreased after 48 h and as a result, a statistically significant difference was found only in the 48-h group (P < 0.05). Conclusion: Along with the shrinked infarct volume, the levels of miR-155 decreased and the S6kb1 mRNA level increased as the leghtening of re-perfusion, as to the mRNA levels of Rheb, mTOR, and 4Ebp1,statistical significance was found only in the 48-h group. Unexpectedly, there was no difference between the ischemic core and the IP area for all the above molecules.Indicating that intervention measures targeting to miR155 should be taken systemicly as early as possible after stroke onset,especially within the early 48 hours.

Background: The aim of this study was to evaluate the morphological changes of patella following surgical correction of recurrent patellar dislocation in children. Methods: 35 immature children aged 5 to 10 years who suffered from bilateral recurrent patellar dislocation associated with abnormal patella morphology. The knee had most frequently patellar dislocation, which was underwent medial patellar retinacular plasty, and defined as in the study group(SG). The contralateral knee was treated conservatively and defined as in the control group (CG). Computed tomography (CT) scans were performed on all children preoperatively and at the last follow-up to evaluate the patellar morphological characteristics. Results: All the radiological parameters of the patella, showed no significant difference between the two groups, Preoperatively. At the last follow-up for CT scans, no signifcant diferences were evaluable for the relative patellar width (SG, 54.61%; CG, 52.87%; p=0.086) and the relative patellar thickness (SG, 26.07% ; CG, 25.02%; p = 0.243). The radiological parameters including Wiberg-angle (SG, 136.25°; CG, 122.65°; p < 0.001), modified Wiberg-index (SG, 1.23; CG, 2.65 ; p < 0.001), and lateral patellar facet angle (SG, 23.35° ; CG, 15.26°; p < 0.001) showed statistical differences between the two groups. Conclusions: The morphology of the patella can be improved by early surgical correction in children with recurrent patellar dislocation. Early intervention for children with recurrent patellar dislocation is important.
The Role of Transient Attention in the Radial-tangential Anisotropy of Crowding
Authors: Kewan-Khalayly Bahiyya , Migó Marta , Yashar Amit
Published: August 2021

Crowding refers to the failure to identify a peripheral object due to its proximity to other objects (flankers). This phenomenon can lead to reading and object recognition impairments, and is associated with macular degeneration, amblyopia, and dyslexia. Crucially, the minimal target-flanker spacing required for the crowding interference (critical spacing) increases with eccentricity. This spacing is also larger when target and flankers appear along the horizontal meridian (radial arrangement) than when the flankers appear above and below the target (tangential arrangement). This phenomenon is known as radial–tangential anisotropy. Previous studies have demonstrated that transient attention can reduce crowding interference. However, it is still unclear whether and how attention interacts with the radial–tangential anisotropy. To address this issue, we manipulated transient attention by using a cue either at the target (valid) or fixation (neutral) location, in both radial and tangential target-flanker arrangements. Results showed that critical spacing was larger in the radial than in the tangential arrangement, and that cueing the target location improved performance and reduced the critical spacing for both radial and tangential arrangements, to the same extent. Together, our findings suggest that transient spatial attention plays an essential role in crowding but not in the radial-tangential anisotropy.

Background

Dysregulation and dysfunction of DNA damage response (DDR) have prognostic and predictive implications for glioblastomas (GBMs) without glioma-CpGs island methylator phenotype (G-CIMP); mathematical modeling based on DNA methylation abnormality in DDR genes may serve as clinically useful biomarkers.
Methods

Independent cohorts of non-G-CIMP GBMs and IDH wild type (wt) lower-grade gliomas (LGGs) from local and public databases were included for discovery and validation of a multimarker signature, combined using a RISK score model. Different bioinformatic and functional experiments were performed for biological validation.
Results

By analyzing DNA methylation microarray data of DDR genes, we totally identified five CpGs, each of which was significantly correlated with overall survival (OS) of non-G-CIMP GBMs, independent of age, treatments and the O-6-methylguanine-DNA methyltransferase (MGMT) methylation status. A RISK score signature of the 5 CpGs was constructed and validated to powerfully and independently prognosticate prognosis in non-G-CIMP GBMs. It also showed good discriminating value in stratified cohorts by patient age and MGMT methylation status. Bioinformatic analysis revealed a close correlation of the DDR epigenetic signature to distinct immunophenotypes of non-G-CIMP GBMs. Functional studies showed that NSUN5, epigenetically regulated by one identified CpGs, exhibited tumor-suppressor characteristics but may have immunosuppressive implications and confer TMZ resistance to GBM cells.
Conclusions

The epigenetic signature of DDR genes might be of promising value for refining current prognostic classification of non-G-CIMP GBMs, and its potential links to distinct immunophenotypes make it a promising biomarker candidate in the coming era of cancer immunotherapy.
