The development of social attention in orangutans: Comparing peering behavior in wild and zoo-housed individuals.

Social learning plays an essential role in all cultural processes, but the factors underlying its evolution remain poorly understood. To understand how socio-ecological conditions affect social learning, we compared peering behavior (i.e.

Rapid changes in plasma corticosterone and medial amygdala transcriptome profiles during social status change reveal molecular pathways associated with a major life history transition in mouse dominance hierarchies.

Social hierarchies are a common form of social organization across species. Although hierarchies are largely stable across time, animals may socially ascend or descend within hierarchies depending on environmental and social challenges. Here, we develop a novel paradigm to study social ascent and descent within male CD-1 mouse social hierarchies.

CIRCUS: CIRCUlating tumour cells in soft tissue Sarcoma - a short report.

Circulating tumour cells (CTCs) can be detected in peripheral blood using their physical properties (increased size and less deformable than normal circulating blood cells) or using cell surface markers. The study of these CTCs should provide important insights into tumour biology, including mechanisms of drug resistance. We performed a pilot study (IRAS ID: 235459) to evaluate if CTCs could be isolated from peripheral blood samples collected from soft tissue sarcoma (STS) patients.

Development of novel GI-centric prostaglandin E receptor type 4 (EP4) agonist prodrugs as treatment for ulcerative colitis and other intestinal inflammatory diseases.

Prostaglandin E receptor type 4 (EP4) agonists have been shown to be effective in treating experimental ulcerative colitis (UC) in animals and in human clinical trials, but their development has been impeded by unacceptable systemic side effects. In this study, a series of methylene phosphate prodrugs of a highly potent and selective prostaglandin EP4 receptor agonist were designed to target and remain localized in the gastrointestinal (GI) tract after either oral or rectal instillation. The prodrugs were designed to be converted to liberate active EP4 agonist by intestinal alkaline phosphate (IAP), a ubiquitous enzyme found at the luminal of the intestinal wall thus exposing the colon epithelial barrier while reducing systemic exposure to the active agonist.

Molecular engineering charge transfer and triplet exciton formation in donor-acceptor cocrystals.

Organic donor-acceptor (D-A) cocrystals are gaining attention for their potential applications in optoelectronic devices. This study explores the dynamics of charge transfer (CT) and triplet exciton formation in various D-A cocrystals. By examining a series of D-A cocrystals composed of coronene (COR), peri-xanthenoxanthene (PXX), and perylene (PER) donors paired with N,N-bis(3'-pentyl)perylene-3,4:9,10-bis(dicarboximide) (PDI), naphthalene-1,4:5,8-tetracarboxy-dianhydride (NDA), or pyrene-4,5,9,10-tetraone (PTO) acceptors, using transient absorption microscopy and time-resolved electron paramagnetic resonance spectroscopy, we find that the strength of the CT interaction influences the nature and yield of triplet excitons produced by CT state recombination.
