Cryptotanshinone inhibits proliferation and induces apoptosis of breast cancer MCF-7 cells via GPER mediated PI3K/AKT signaling pathway

G protein-coupled estrogen receptor (GPER) was reported to be a potential target in the breast cancer therapy. This study aimed to illuminate the function of GPER and its mediated PI3K/AKT pathway in cryptotanshinone (CPT) inducing cell apoptosis and antiproliferation effect on GPER positive breast cancer MCF-7 cells. Cell proliferation was tested by MTT assay. Apoptosis rates were tested by Annexin V-FITC/PI double staining and the cell cycle was researched by flow cytometry. Autodock vina was applied to make molecular docking between CPT or estradiol and GPER. siRNA technique and GPER specific agonist G-1 or antagonist G-15 were applied to verify the mediated function of GPER. Apoptosis and cell cycle related proteins, as well as the key proteins on PI3K/AKT signaling pathway were detected by western blot. The results indicated that CPT could exert antiproliferation effects by arresting cell cycle in G2/M phase and downregulating the expression of cyclin D, cyclin B and cyclin A. Besides, apoptosis induced by CPT was observed. CPT might be a novel GPER binding compounds. Significantly, suppression of PI3K/AKT signal transduction by CPT was further increased by G-1 and decreased by G-15. The study revealed that the effect of antiproliferation and apoptosis treating with CPT on MCF-7 cells might be through the downregulation of PI3K/AKT pathway mediated by activated GPER.
A Collision Relationship-Based Driving Behavior Decision-Making Method for an Intelligent Land Vehicle at a Disorderly Intersection via DRQN

An intelligent land vehicle utilizes onboard sensors to acquire observed states at a disorderly intersection. However, partial observation of the environment occurs due to sensor noise. This causes decision failure easily. A collision relationship-based driving behavior decision-making method via deep recurrent Q network (CR-DRQN) is proposed for intelligent land vehicles. First, the collision relationship between the intelligent land vehicle and surrounding vehicles is designed as the input. The collision relationship is extracted from the observed states with the sensor noise. This avoids a CR-DRQN dimension explosion and speeds up the network training. Then, DRQN is utilized to attenuate the impact of the input noise and achieve driving behavior decision-making. Finally, some comparative experiments are conducted to verify the effectiveness of the proposed method. CR-DRQN maintains a high decision success rate at a disorderly intersection with partially observable states. In addition, the proposed method is outstanding in the aspects of safety, the ability of collision risk prediction, and comfort.
Projected changes in bird assemblages due to climate change in a Canadian system of protected areas

National parks often serve as a cornerstone for a country’s species and ecosystem conservation efforts. However, despite the protection these sites afford, climate change is expected to drive a substantial change in their bird assemblages. We used species distribution models to predict the change in environmental suitability (i.e., how well environmental conditions explain the presence of a species) of 49 Canadian national parks during summer and winter for 434 bird species under a 2°C warming scenario, anticipated to occur in Canada around the mid-21st century. We compared these to existing species distributions in the 2010s, and classified suitability projections for each species at each park as potential extirpation, worsening, stable, improving, or potential colonisation. Across all parks, and both seasons, 70% of the projections indicate change, including a 25% turnover in summer assemblages and 30% turnover in winter assemblages. The majority of parks are projected to have increases in species richness and functional traits in winter, compared to a mix of increases and decreases in both in summer. However, some changes are expected to vary by region, such as Arctic region parks being likely to experience the most potential colonisation, while some of the Mixedwood Plains and Atlantic Maritime region parks may experience the greatest turnover and potential extirpation in summer if management actions are not taken to mitigate some of these losses. Although uncertainty exists around the precise rate and impacts of climate change, our results indicate that conservation practices that assume stationarity of environmental conditions will become untenable. We propose general guidance to help managers adapt their conservation actions to consider the potentially substantive changes in bird assemblages that are projected, including managing for persistence and change.
Persisting Effects of a Social Media Campaign to Prevent Indoor Tanning: A Randomized Trial.

BACKGROUND A social media campaign for mothers aimed at reducing indoor tanning (IT) by of adolescent daughters reduced mothers' permissiveness toward IT in an immediate posttest. Whether the effects persisted at six months after the campaign remains to be determined. METHODS Mothers (N=869) of daughters aged 14-17 in 34 states without bans on IT by minors were enrolled in a randomized trial. All mothers received an adolescent health campaign over 12 months with posts on preventing IT (intervention) or prescription drug misuse (control). Mothers completed a follow-up at 18-months post-randomization measuring IT permissiveness, attitudes, intentions, communication, and behavior, and support for state bans. Daughters (n=469; 54.0%) just completed baseline and follow-up surveys. RESULTS Structural equation modeling showed that intervention-group mothers were less permissive of IT by daughters (unstandardized coefficient=-0.17, 95% confidence interval [CI], -0.31, -0.03), had greater self-efficacy to refuse daughter's IT requests (0.17, 95% CI, 0.06, 0.29) and lower IT intentions themselves (-0.18, 95% CI, -0.35, -0.01), and were more supportive of bans on IT by minors (0.23, 95% CI, 0.02, 0.43) than control-group mothers. Intervention-group daughters expressed less positive IT attitudes than controls (-.16, 95% CI, 0.31, -0.01). CONCLUSIONS The social media campaign may have had a persisting effect of convincing mothers to withhold permission for daughters to indoor tan for six months after its conclusion. Reduced IT intentions and increased support for bans on IT by minors also persisted among mothers. IMPACT Social media may increase support among mothers to place more restrictions on IT by minors.
Thinking, not talking, predicts knowledge level: Effects of media attention and reflective integration on public knowledge of nuclear energy

By applying the cognitive mediation model, this study seeks to investigate factors influencing public knowledge of nuclear energy in Singapore. In addition, this study seeks to extend the cognitive mediation model by explicating the knowledge variable into four facets – general science knowledge, perceived familiarity, content nuclear knowledge and contextual nuclear knowledge. Using data collected from an interviewer-led door-to-door survey with 1000 Singapore citizens and permanent residents (PRs), we found that attention to TV news, website news and social media news stimulated news elaboration and interpersonal discussion. However, attention to print newspaper was neither associated with news elaboration nor interpersonal discussion. We also found that news elaboration could enhance factual knowledge such as general science knowledge, content nuclear knowledge and contextual nuclear knowledge, while interpersonal discussion could enhance perceived familiarity. Theoretical and practical implications are discussed.
Hao1 Is Not a Pathogenic Factor for Ectopic Ossifications but Functions to Regulate the TCA Cycle In Vivo

Ossification of the posterior longitudinal ligament (OPLL), a disease characterized by the ectopic ossification of a spinal ligament, promotes neurological disorders associated with spinal canal stenosis. While blocking ectopic ossification is mandatory to prevent OPLL development and progression, the mechanisms underlying the condition remain unknown. Here we show that expression of hydroxyacid oxidase 1 (Hao1), a gene identified in a previous genome-wide association study (GWAS) as an OPLL-associated candidate gene, specifically and significantly decreased in fibroblasts during osteoblast differentiation. We then newly established Hao1-deficient mice by generating Hao1-flox mice and crossing them with CAG-Cre mice to yield global Hao1-knockout (CAG-Cre/Hao1flox/flox; Hao1 KO) animals. Hao1 KO mice were born normally and exhibited no obvious phenotypes, including growth retardation. Moreover, Hao1 KO mice did not exhibit ectopic ossification or calcification. However, urinary levels of some metabolites of the tricarboxylic acid (TCA) cycle were significantly lower in Hao1 KO compared to control mice based on comprehensive metabolomic analysis. Our data indicate that Hao1 loss does not promote ectopic ossification, but rather that Hao1 functions to regulate the TCA cycle in vivo.
User Experience Design: Aesthetics or Functionality?

Most of the time, just designing a perfect looked interface is not enough for users to use it properly. Generally designers tend to consider the things from their own side, but in order to design a useful interface, they need to see the process through users’ eyes. The purpose of the User Experience (UX) is to increase customer satisfaction and sales by providing the largest ease of use, benefit and enjoy for users. A product can only exist as long as it fulfills the user’s needs with its functionality. On the other hand importance of aesthetics cannot be ignored. It is the visual interaction and attractiveness which make a connection between user and product. In this paper, it is planned to investigate the importance of (and also relationship between) functionality and aesthetics of (web) interfaces from the eyes of users. A survey designed to measure different aspects of aesthetics and functionality is conducted to 41 web users. The results supported with statistical and managerial implications provide useful information for product managers, designers and also for users.
Global monitoring strategy for multimode chemical processes

Multivariate statistical process monitoring(SPM)has gained tremendous attention in both academic and industrial circles over the past two decades.Most of the existing statistical monitoring algorithms are established on the assumption that the monitored industrial processes work under single operating mode.However,in order to meet the demands of markets,multimode has become a significant feature of modern chemical industry.To meet the monitoring demands of multimode processes,a global monitoring strategy based on locality preserving projection(LPP)and Gaussian mixture model(GMM)is proposed.By integrating probability indices of each operating modes,the online monitoring is guaranteed to be continuous and uninterrupted.The efficiency and effectiveness of the novel monitoring strategy is verified though the Tennessee Eastman(TE)simulation platform.
Multicontrast investigation of in vivo wildtype zebrafish in three development stages using polarization-sensitive optical coherence tomography

Abstract. Significance: The scattering and polarization characteristics of various organs of in vivo wildtype zebrafish in three development stages were investigated using a non-destructive and label-free approach. The presented results showed a promising first step for the usability of Jones-matrix optical coherence tomography (JM-OCT) in zebrafish-based research. Aim: We aim to visualize and quantify the scatter and polarization signatures of various zebrafish organs for larvae, juvenile, and young adult animals in vivo in a non-invasive and label-free way. Approach: A custom-built polarization-sensitive JM-OCT setup in combination with a motorized translation stage was utilized to investigate live zebrafish. Depth-resolved scattering (intensity and attenuation coefficient) and polarization (birefringence and degree of polarization uniformity) properties were analyzed. OCT angiography (OCT-A) was utilized to investigate the vasculature label-free and non-destructively. Results: The scatter and polarization signatures of the zebrafish organs such as the eye, gills, and muscles were investigated. The attenuation coefficient and birefringence changes between 1- and 2-month-old animals were evaluated in selected organs. OCT-A revealed the vasculature of in vivo larvae and juvenile zebrafish in a label-free manner. Conclusions: JM-OCT offers a rapid, label-free, non-invasive, tissue specific, and three-dimensional imaging tool to investigate in vivo processes in zebrafish in various development stages.
Biocompatible and Thermoresistant Hydrogels Based on Collagen and Chitosan

Hydrogels are considered good biomaterials for soft tissue regeneration. In this sense, collagen is the most used raw material to develop hydrogels, due to its high biocompatibility. However, its low mechanical resistance, thermal stability and pH instability have generated the need to look for alternatives to its use. In this sense, the combination of collagen with another raw material (i.e., polysaccharides) can improve the final properties of hydrogels. For this reason, the main objective of this work was the development of hydrogels based on collagen and chitosan. The mechanical, thermal and microstructural properties of the hydrogels formed with different ratios of collagen/chitosan (100/0, 75/25, 50/50, 25/75 and 0/100) were evaluated after being processed by two variants of a protocol consisting in two stages: a pH change towards pH 7 and a temperature drop towards 4 °C. The main results showed that depending on the protocol, the physicochemical and microstructural properties of the hybrid hydrogels were similar to the unitary system depending on the stage carried out in first place, obtaining FTIR peaks with similar intensity or a more porous structure when chitosan was first gelled, instead of collagen. As a conclusion, the synergy between collagen and chitosan improved the properties of the hydrogels, showing good thermomechanical properties and cell viability to be used as potential biomaterials for Tissue Engineering.
A Cas6-based RNA tracking platform functioning in a fluorescence-activation mode

Abstract Given the fact that the localization of RNAs is closely associated with their functions, techniques developed for tracking the distribution of RNAs in live cells have greatly advanced the study of RNA biology. Recently, innovative application of fluorescent protein-labelled Cas9 and Cas13 into live-cell RNA tracking further enriches the toolbox. However, the Cas9/Cas13 platform, as well as the widely-used MS2-MCP technique, failed to solve the problem of high background noise. It was recently reported that CRISPR/Cas6 would exhibit allosteric alteration after interacting with the Cas6 binding site (CBS) on RNAs. Here, we exploited this feature and designed a Cas6-based switch platform for detecting target RNAs in vivo. Conjugating split-Venus fragments to both ends of the endoribonuclease-mutated Escherichia coli Cas6(dEcCas6) allowed ligand (CBS)-activated split-Venus complementation. We name this platform as Cas6 based Fluorescence Complementation (Cas6FC). In living cells, Cas6FC could detect target RNAs with nearly free background noise. Moreover, as minimal as one copy of CBS (29nt) tagged in an RNA of interest was able to turn on Cas6FC fluorescence, which greatly reduced the odds of potential alteration of conformation and localization of target RNAs. Thus, we developed a new RNA tracking platform inherently with high sensitivity and specificity.
Translation and psychometric evaluation of chronic illness anticipated stigma scale (CIASS) among patients in Ethiopia

Background Stigma is common among patients with chronic illnesses. It affects the delivery of healthcare for not addressing the psychological components and may interfere with the patient’s attendance to necessary health care services. Therefore, a valid and reliable instrument to measure anticipated stigma related to chronic illness is vital to inform possible interventions. This study aimed to translate the Chronic Illness Anticipated Stigma Scale (CIASS) into the Amharic language and evaluate its psychometric properties in Ethiopia. Methods The CIASS was translated into Amharic language using standard procedures. The Amharic version was completed by 173 patients (response rate 96%) with chronic illness from three referral hospitals in the Amhara region. Internal consistency was examined through Cronbach’s alpha. Construct validity was evaluated by confirmatory factor analysis and convergent validity by using a Pearson correlation of P-value less than or equal to 0.05. Results The internal consistency was estimated at Cronbach alpha of 0.92. By using a structural equation model, and modification indices a model fitness testing was run and shows a root mean squared error of approximation 0.049 (90% CI, 0.012–0.075). The structural validity results in 78.8% of confirmatory factor analysis showed from the extraction of the three-dimension (components). Validity tests for convergent by using Pearson correlation positively correlated with common mental distress and negatively correlated with quality of life–BREF, and the construct validity shows a good valid tool to CIASS. Conclusion The Amharic language version of the chronic illness anticipated stigma scale shows a satisfactory level of reliability and validity on different psychometric measures of assessment. The tool may be useful for future researchers and patients with chronic illness in the Amharic-speaking population. Moreover, it will be used to see the psychological burden related to chronic illness and for comparison among international population groups.
Bisulfite-initiated crosslinking of gelatin methacryloyl hydrogels for embedded 3D bioprinting

Recent studies on three-dimensional (3D) bioprinting of cell-laden gelatin methacryloyl (GelMA) hydrogels have provided promising outcomes for tissue engineering applications. However, the reliance on the use of photo-induced gelation processes for the bioprinting of GelMA and the lack of an alternative crosslinking process remain major challenges for the fabrication of cell-laden structures. Here, we present a novel crosslinking approach to form cell-laden GelMA hydrogel constructs through 3D embedded bioprinting without using any external irradiation that could drastically affect cell viability and functionality. This approach consists of a one-step type of crosslinking via bisulfite-initiated radical polymerization, which is combined with embedded bioprinting technology to improve the structural complexity of printed structures. By this means, complex-shaped hydrogel bio-structures with cell viability higher than 90% were successfully printed within a support bath including sodium bisulfite. This study offers an important alternative to other photo-induced gelation processes to improve the bio-fabrication of GelMA hydrogel with high cell viability.
Nationwide COVID-19-EII Study: Incidence, Environmental Risk Factors and Long-Term Follow-Up of Patients with Inflammatory Bowel Disease and COVID-19 of the ENEIDA Registry

We aim to describe the incidence and source of contagion of COVID-19 in patients with IBD, as well as the risk factors for a severe course and long-term sequelae. This is a prospective observational study of IBD and COVID-19 included in the ENEIDA registry (53,682 from 73 centres) between March–July 2020 followed-up for 12 months. Results were compared with data of the general population (National Centre of Epidemiology and Catalonia). A total of 482 patients with COVID-19 were identified. Twenty-eight percent were infected in the work environment, and 48% were infected by intrafamilial transmission, despite having good adherence to lockdown. Thirty-five percent required hospitalization, 7.9% had severe COVID-19 and 3.7% died. Similar data were reported in the general population (hospitalisation 19.5%, ICU 2.1% and mortality 4.6%). Factors related to death and severe COVID-19 were being aged ≥ 60 years (OR 7.1, 95% CI: 1.8–27 and 4.5, 95% CI: 1.3–15.9), while having ≥2 comorbidities increased mortality (OR 3.9, 95% CI: 1.3–11.6). None of the drugs for IBD were related to severe COVID-19. Immunosuppression was definitively stopped in 1% of patients at 12 months. The prognosis of COVID-19 in IBD, even in immunosuppressed patients, is similar to that in the general population. Thus, there is no need for more strict protection measures in IBD.
Antiviral Property of the Fungal Metabolite 3-O-Methylfunicone in Bovine Herpesvirus 1 Infection

Bovine herpesvirus type-1 (BoHV-1) is a widespread pathogen that provokes infectious rhinotracheitis and polymicrobial infections in cattle, resulting in serious economic losses to the farm animal industry and trade restrictions. To date, non-toxic active drugs against BoHV-1 are not available. The exploitation of bioactive properties of microbial products is of great pharmaceutical interest. In fact, fungi are a promising source of novel drugs with a broad spectrum of activities and functions, including antiviral properties. Hence, the potential antiviral properties of 3-O-methylfunicone (OMF), a secondary metabolite produced by Talaromyces pinophilus, were evaluated on BoHV-1. In this study, during BoHV-1 infection in bovine cells (MDBK), the non-toxic concentration of 5 µM OMF considerably reduced signs of cell death and increased cell proliferation. Furthermore, OMF significantly decreased the virus titer as well as the cytopathic effect and strongly inhibited the expression of bICP0, the major regulatory protein in the BoHV-1 lytic cycle. These findings were accompanied by a considerable up-regulation in the expression of the aryl hydrocarbon receptor (AhR), a multifunctional transcription factor also linked to the host’s response to a herpesvirus infection. Overall, our results suggest that by involving AhR, OMF shows potential against a BoHV-1 infection.
Satellite altimetry for meteorological and oceanographic applications

Satellite altimeter is a remote sensing sensor providing an integrated picture of the atmosphere and the oceans over large spatial and temporal scales. Though the principle of obtaining altimeter range from the sea surface is simple, quite a good number of corrections have to be applied to the two way travel time. The various sources of errors in the altimeter measurements and the corrections to be applied are described. The potential applications of altimeter measurements in meteorology and oceanography are also discussed.
