Is self-enhancement culturally universal or relativistic? This article highlights a nuanced dynamic in East Asian culture. Modesty is a prevailing norm in China. The authors hypothesized that because of socialization practices and prohibitive cultural pressures, modesty would be associated with and lead to low explicit self-enhancement but high implicit self-enhancement, that Chinese participants would deemphasize explicitly the positivity of the self when high on modesty or situationally prompted to behave modestly but would capitalize on their modest disposition or situationally induced behavior to emphasize implicitly the positivity of the self. In support of the hypotheses, dispositionally or situationally modest Chinese participants manifested low explicit self-esteem while manifesting high implicit self-esteem. Modesty among American participants constrained explicit self-esteem but yielded no associations with implicit self-esteem. The results showcase the tactical nature of self-enhancement in Chinese culture and call for research on when and how self-enhancement is pursued tactically in different cultures.

The iodofunctionalization of ferrocenylallene with carboxylic acids, phenols, and alcohols is described. The reaction proceeds smoothly in the presence of molecule iodine as a halonium promoter and using various carboxylic acids, phenols, and alcohols as nucleophiles to give the corresponding ferrocene-containing β-iodoallylic ester and ether products in moderate to high yields and with high regio- and stereoselectivities. It can be envisaged that the regio- and stereoselectivity of this reaction may be controlled by the steric effect of the bulky ferrocene group. The presence of the C-I bond in the corresponding products makes these molecules highly attractive from a synthetic point of view, as it provides an opportunity for further transformations. Thus, palladium-catalyzed Heck coupling, Suzuki coupling, Sonogashira coupling, and copper-catalyzed click reactions were carried out successfully.

A palladium-catalyzed three-component intermolecular aryl­etherification reaction of ferrocene-substituted allenes, aryl iodides and phenols or alcohols is reported. In this three-component reaction, two new C–C and C–O bonds are formed in one step with high regio- and stereoselectivity. The high selectivity obtained in this reaction can be attributed to the steric effect of the bulky ferrocene group.

Interferons and chemokines-mediated immune responses are two general antiviral programs of the innate immune system in response to viral infections and have recently emerged as important players in systemic metabolism. In this study, we found that the chemokine CCL4 is negatively regulated by glucose metabolism and avian leukosis virus subgroup J (ALV-J) infection in chicken macrophages. This immune response is defined by low expression levels of CCL4 by high glucose treatment or ALV-J infection. Moreover, the ALV-J envelope protein is responsible for CCL4 inhibition. We further confirmed that CCL4 can inhibit glucose metabolism and ALV-J replication in chicken macrophages. The present study provides novel insights into the antiviral defence mechanism and metabolic regulation of the chemokine CCL4 in chicken macrophages.
