Metabolites from intestinal microbes modulate the mucosal immune system by regulating the polarization and expansion of T cells. Whether the microbial metabolites influence macrophage polarization, however, is poorly understood. Here, we show that the large bowel microbial fermentation product, butyrate, facilitates M2 macrophage polarization, in vitro and in vivo. The supernatant from butyrate-treated M2 macrophage increased the migration and enhanced the wound closure rate of MLE-12 cells. Butyrate attenuated intestinal inflammation in mice with dextran sulfate sodium (DSS)-induced colitis, with a significant increase in colonic expression of the M2 macrophage-associated protein, Arg1. M2 macrophage treated with butyrate, had increased activation of the H3K9/STAT6 signaling pathway, suggesting a mechanism for butyrate facilitated M2 macrophage polarization. Collectively, our study indicated that commensal microbe-derived butyrate is a novel activator of STAT6-mediated transcription through H3K9 acetylation driving M2 macrophage polarization, and delineated new insights into the immune interplay underlying inflammatory bowel disease.

Objective: To explore treatment decision-making experiences of Australian migrants with cancer from Arabic, Chinese, or Greek backgrounds and their relatives.Methods: 73 patients and 18 caregivers from cancer support groups and oncology clinics participated in either a focus group (n=14) or semi-structured interview (n=21) conducted in the participant's own language. Participant treatment decision-making preferences were discussed as part of patients' overall treatment experience and a thematic analysis conducted.Results: Four main themes emerged from the data:(1) perceived role of the patient in decision-making;(2) access to information and the impact of language; (3)cultural influences (4)family involvement. The majority of participants experienced passive involvement during treatment consultations, but expressed a desire for greater involvement. Language rather than culture was a greater obstacle to active participation. Difficulty communicating effectively in English was the most significant barrier to participation in treatment decisions. To overcome language challenges, participants actively sought information from alternative sources. Conclusion and practice implications:This study provides new insights into the influence of language and culture on the treatment decision-making experiences of migrants with cancer and their families within the Australian cancer care system. To reduce health disparities doctors need to address language difficulties and be aware of cultural differences.

The MYB transcription factor family members have been reported to play different roles in plant growth regulation, defense response, and secondary metabolism. However, MYB gene expression has not been reported in Panax ginseng. In this study, we isolated a gene from ginseng adventitious root, PgMYB2, which encodes an R2R3-MYB protein. Subcellular localization revealed that PgMYB2 protein was exclusively detected in the nucleus of Allium cepa epidermis. The highest expression level of PgMYB2 was found in ginseng root and it was significantly induced by plant hormones methyl jasmonate (MeJA). Furthermore, the binding interaction between PgMYB2 protein and the promoter of dammarenediol synthase (DDS) was found in the yeast strain Y1H Gold. Moreover, the electrophoretic mobility shift assay (EMSA) identified the binding site of the interaction and the results of transiently overexpressing PgMYB2 in plants also illustrated that it may positively regulate the expression of PgDDS. Based on the key role of PgDDS gene in ginsenoside synthesis, it is reasonable to believe that this report will be helpful for the future studies on the MYB family in P. ginseng and ultimately improving the ginsenoside production through genetic and metabolic engineering.

Top-gated and bottom-gated transistors with multilayer MoS channel fully encapsulated by stacked AlO/HfO (9 nm/6 nm) were fabricated and comparatively studied. Excellent electrical properties are demonstrated for the TG transistors with high on-off current ratio of 10, high field-effect mobility of 10 cm V s, and low subthreshold swing of 93 mV dec. Also, enhanced reliability has been achieved for the TG transistors with threshold voltage shift of 10-10 V MV cm after 6 MV cm gate-biased stressing. All improvement for the TG device can be ascribed to the formed device structure and dielectric environment. Degradation of the performance for the BG transistors should be attributed to reduced gate capacitance density and deteriorated interface properties related to vdW gap with a thickness about 0.4 nm. So, the TG transistor with MoS channel fully encapsulated by stacked AlO/HfO is a promising way to fabricate high-performance ML MoS field-effect transistors for practical electron device applications.
