Abstract
Siglec-15 is an immune suppressor with broad upregulation on various cancer types and has emerged as a potential target for cancer immunotherapy. However, it remains unclear how SIGLEC15 expression is controlled in normal or cancer cells. In this work, we utilized reporter assays to evaluate the impact of the 5' UTR and the 3' UTR of SIGLEC15 mRNA on gene expression. We found that the 3' UTR dramatically reduced reporter protein production, whereas the 5' UTR showed modest inhibitory effect. Quantification of steady-state mRNA revealed the good coupling of protein amount and mRNA abundance that was associated with the 3' UTR. In contrast, the 5' UTR had little effect on mRNA abundance compared with the empty control. By measuring mRNA half-life, we showed that the 3' UTR markedly promoted mRNA degradation. Testing shortened 3' UTR fragments demonstrated five out of the six having notable inhibitory effect, with the one spanning 993-1317 had the most robust activity. More interestingly, the 993-1317 region contains a predicted 43-nt stem-loop structure that showed apparent inhibitory activity in four cell lines tested. These results suggested that the 3' UTR inhibited reporter gene expression by accelerating mRNA decay possibly via multiple cis-regulatory elements, but the 5' UTR repressed gene expression by inhibiting translation. Thus, our findings provided a clue to the molecular mechanism underlying the regulation of SIGLEC15 expression.

Abstract
Background: The close relationship between colorectal cancer and inflammation has been widely reported. However, the relationship between colorectal cancer and inflammation at the genetic level is not fully understood.Method: From a genetic perspective, this study explored the relationship between inflammation-related genes and the immune microenvironment in colorectal cancer. We identified prognostic genes, namely CX3CL1, CCL22, SERPINE1, LTB4R, XCL1, GAL, TIMP1, ADIPOQ, and CRH, by using univariate and multivariate regression analyses. A risk scoring model for inflammatory response was established, and patients in The Cancer Genome Atlas (TCGA) database and Gene Expression Omnibus (GEO) database were divided into two groups: high risk group and low risk group.Results: The analysis showed that the prognosis of the two groups was significantly different, and the low-risk group had a higher survival rate and longer survival time. Pathways related to apoptosis, inflammatory response, and hypoxia were significantly enriched as shown via Gene Set Enrichment Analysis (GSEA). Activated dendritic cell infiltration was found in both the TCGA and GEO databases, and the CCL21 gene played a significant role in the process of activated dendritic cell infiltration. CCL21 gene was also positively correlated with inflammatory response, and the gene expression and risk score were significantly different between the two groups.Conclusion: In summary, inflammatory response has a direct impact on patients with colorectal cancer in the prognosis and immune infiltration and further research studies on the inflammatory response can help in advancing the development of immunotherapy for colorectal cancer.

Abstract
We show that optical properties change when the fullerene structures of Au32, Cu32and Ag32inflate and deflate. We first observe significant differences in the extinction spectra employing a classical approach based on the Green's dyadic method. By means of real-time time-dependent density functional theory. We continue to calculate the optical spectrum (OP) via aδ-kick simulation, comparing results with the ground-state energetic property the HOMO-LUMO (HL) gap. Red-shift of the OP is expected as the fullerenes inflate, with only ±10% change in the size. As the fullerene breathes, a 0.8 eV shift in the first peak position could be observed in the gold nanoparticle. Ag has a smoother behaviour than both Au and Cu. We have also found changes in the optical spectra can not be directly interpreted as a result of changes in the HL gap.

Abstract
Abstract
For larger containments and higher operation parameters, characteristics of the outside cooling of the PCCS are very important for the analysis on the containment integrity. A preliminary analysis was made and a four-step experimental method was used to numerically analyze the falling water film evaporation for the advanced passive containment. Then, the water flow stability along the outside wall of the containment was studied. The results fit well with those correlations without airflow when the air velocity is less than 5.0 m/s. However, when the air velocity is larger than 5.0 m/s, the influence of the air velocity on the water film will appear and the mean water film thickness will be thicker. Based on the prototype operation parameters, experimental studies were carried and the results were compared with the Dittus-Boelter correlation within the operation ranges. A modification factor was proposed for the conservative application of this correlation for nuclear safety analysis.

Abstract
BACKGROUND Hyperpigmented spots are common issues in all ethnicities, involving multiple intrinsic and extrinsic factors such as UVB exposure, hormone balance, inflammatory status and ageing. OBJECTIVES To determine (i) melanocyte dendricity in multiple facial spot types, (ii) impact of High Mobility Group Box 1 (HMGB1), and the combination of sucrose dilaurate and sucrose laurate (SDL) on melanogenesis and melanocyte dendricity, and (iii) SDL effect on facial spots in a human use test. METHODS Facial spot and adjacent non-spot skin biopsies were collected from Chinese women (age 20-70). Histological assessment of melanocyte dendricity was performed for 3 spot types (solar lentigo, melasma and postinflammatory hyperpigmentation) by immunofluorescent staining for c-kit/MITF. Keratinocyte, melanocyte and melanocyte-keratinocyte co-culture models were used to assess HMGB1 release by UVB radiation, the effects of HMGB1 and SDL on melanin production, melanocyte dendricity and melanosome transfer. The effect of an SDL-containing moisturizer on appearance of facial hyperpigmented spots was assessed against a vehicle control in an 8-week human use test. RESULTS Melanocytes in spot areas are more dendritic than melanocytes in adjacent non-spot skin across three investigated spot types. In cell culture models, a moderate UVB-radiation exposure caused release of HMGB1 from keratinocytes. HMGB1 did not alter melanin production in melanocytes, but enhanced melanocyte dendricity and melanosome transfer. SDL reduced HMGB1 release from keratinocytes, inhibited melanin production, reversibly suppressed melanocyte dendricity and reduced melanosome transfer. In the human use test, SDL-containing moisturizer reduced appearance of spots versus vehicle. CONCLUSION Increased melanocyte dendricity was observed in multiple types of facial spots. Addition of HMGB1 protein increased melanocyte dendricity and melanosome transfer in cell cultures, implicating potential involvement in spot formation. SDL suppressed melanin production, melanocyte dendricity and melanosome transfer in vitro and reduced appearance of spots in the use test, suggesting SDL is an effective solution to address hyperpigmented spot concerns.

Abstract
Pig production faces seasonal fluctuations. The low farrowing rate of sows mated in summer, increased carcass fatness of progeny born to the sows mated in summer, and slower growth rate of finisher pigs in summer are three economically important impacts identified in the pig industry. The purpose of this review is to examine advances over the past decade in understanding the mechanisms underlying the three impacts associated with summer conditions, particularly heat stress (HS), and to provide possible amelioration strategies. For impact 1, summer mating results in low farrowing rates mainly caused by the high frequency of early pregnancy disruptions. The contributions of semen DNA damage, poor oocyte quality, local progesterone concentrations, and suboptimal embryonic oestrogen secretion are discussed, as these all may contribute to HS-mediated effects around conception. Despite this, it is still unclear what the underlying mechanisms might be and thus, there is currently a lack of commercially viable solutions. For impact 2, there have been recent advances in the understanding of gestational HS on both the sow and foetus, with gestational HS implicated in decreased foetal muscle fibre number, a greater proportion of lighter piglets, and increased carcass fatness at slaughter. So far, no effective strategies have been developed to mitigate the impacts associated with gestational HS on foetuses. For impact 3, the slowed growth rate of pigs during summer is one reason for the reduced carcass weights in summer. Studies have shown that the reduction in growth rates may be due to more than reductions in feed intake alone, and the impaired intestinal barrier function and inflammatory response may also play a role. In addition, it is consistently reported that HS attenuates fat mobilisation which can potentially exacerbate carcass fatness when carcass weight is increased. Novel feed additives have exhibited the potential to reduce the impacts of HS on intestinal barrier function in grower pigs. Collectively, based on these three impacts, the economic loss associated with HS can be estimated. A review of these impacts is warranted to better align the future research directions with the needs of the pig industry. Ultimately, a better understanding of the underlying mechanisms and continuous investments in developing commercially viable strategies to combat HS will benefit the pig industry.

Abstract
The technological advancement heralded the arrival of precision radiotherapy (RT), thereby increasing the therapeutic ratio and decreasing the side effects from treatment. Contour of target volumes (TV) and organs at risk (OARs) in RT is a complicated process. In recent years, automatic contouring of TV and OARs has rapidly developed due to the advances in deep learning (DL). This technology has the potential to save time and to reduce intra- or inter-observer variability. In this paper, the authors provide an overview of RT, introduce the concept of DL, summarize the data characteristics of the included literature, summarize the possible challenges for DL in the future, and discuss the possible research directions.
