Opis:
Research background: The twin pressures of economic downturn and climate change faced by countries around the world have become more pronounced over the past decade. A renewable energy transition is believed to play a central role in mitigating the economic-climate paradox. While the architectural and computational power of artificial intelligence is particularly well suited to address the challenges of massive data processing and demand forecasting during a renewable energy transition, there is very scant empirical assessment that takes a social science perspective and explores the effects of AI development on the energy transition. Purpose of the article: This paper aims to answer two key questions: One is, how does AI software development promote or inhibit the shift of energy consumption towards renewables? The other is, under what policy interventions does AI software development have a more positive effect on promoting renewable energy consumption? Methods: We employ a dataset of 62 economies covering the period 2011–2020 to analyze the impact of AI software development on the energy transition, where possible confounders, including political and economic characteristics and time-invariant elements, are controlled using fixed-effects estimation along with specified covariates. Findings & value added: AI software development can promote the energy transition towards renewables. There is suggestive evidence that the core mechanism linking such a positive relationship tends to lie in improving innovation performance in environmental monitoring rather than in green computing. Government support for R&D in renewable energy technologies is found to be significantly beneficial for harnessing the positive impact of AI software development on the energy transition. Compared to non-market-based environmental policies, market-based environmental policies have a more significant positive moderating effect on the relationship between AI software development and energy transition.

Opis:
Lavender (Lavandula angustifolia) is an important medicinal and aromatic plant. However, the application of lavender essential oil (LEO) is limited by its instability, low solubility and high volatility. Therefore, to improve the stabilities and antioxidant activities of LEO and thereby expand the applications, LEO was microencapsulated by metal-organic frameworks based on β-cyclodextrin and potassium cation (K-βCD-MOFs) with different mass core/wall ratios. The results showed that the best inclusion rate was 96.67% with the ratio of 1:10. Then, the optimum inclusion product was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The thermal and pH stabilities and the intracellular antioxidant activities were also studied. The results showed that the stabilities of the oil with K-βCD-MOFs inclusions and their abilities to resist acid and alkali were significantly stronger than those of LEO itself. In addition, the intracellular antioxidant activities of LEO were also enhanced by the K-βCD-MOFs inclusion. These results suggested the potential of K-βCD-MOFs as carriers for essential oils in food industry applications.

Opis:
Numerous evidences suggested that the hepatitis B virus (HBV) was recognized as an important factor in the development of hepatocellular carcinoma (HCC). Dickkopf-1 (DKK1) recently was reported to be involved in the progress of HCC. HBV may regulate DKK1 expression in hematoma carcinogenesis. Here, we demonstrated that HBV could regulate DKK1 promoter activity which resulted in upregulation of its mRNA and protein expression in several HBV existing cell lines, and HBx played a prominent role in this process. Transcription factor binding site search result showed that there is a SP1 site in DKK1 promoter region. Luciferase assay showed that overexpression of SP1 could increase DKK1 promoter activity in a dose dependent manner. Accordingly, siRNA inhibition of SP1 expression reduced DKK1 promoter activity and decreased the expression of DKK1 protein.

Hsa-miR-331-3p and VHL
Opis:
Dysregulation of miRNA is widely involved in human cancers, including hepatocellular carcinoma (HCC). Array data for miRNAs indicated that miR-331-3p might be one of the disorderly expressed miRNAs in HCC cell lines, but the function of miR-331-3p in HCC remains unclear. In this study, quantitative real time polymerase chain reaction (qRT-PCR) results indicated that miR-331-3p was up-regulated in HepG2.2.15 cells, Ad-HBV-HepG2 cells and pCH9/3091transfected SMMC7721 cells compared with their control group, respectively. miRNA target prediction software was used, and VHL was found to be one of the target genes of miR-331-3p. qRT-PCR and western blot analysis indicated VHL expression was decreased when miR-331-3p was over-expressed and increased when miR-331-3p was inhibited in SMMC7721 cells. The luciferase reporter activity was inhibited in SMMC7721 cells when co-transfected with miR-331-3p expression vector and VHL 3'-UTR wild type vector and increased in HepG2.2.15 transfected with miR-331-3p inhibitor compared to its control group respectively. When co-transfected with miR-331-3p expression vector and VHL 3'-UTR mutated type vector in SMMC7721 cells the luciferase reporter activity was recovered. All of these results show that HBV up-regulated miR-331-3p expression in HCC cell lines and miR-331-3p could inhibit VHL expression by directly targeting its 3'-UTR. This provided useful information in exploring the mechanism of HCC induced by HBV infection.
