Dogs do not use their own experience with novel barriers to infer others' visual access.

Despite extensive research into the Theory of Mind abilities in non-human animals, it remains controversial whether they can attribute mental states to other individuals or whether they merely predict future behaviour based on previous behavioural cues. In the present study, we tested pet dogs (in total, = 92) on adaptations of the 'goggles test' previously used with human infants and great apes. In both a cooperative and a competitive task, dogs were given direct experience with the properties of novel screens (one opaque, the other transparent) inserted into identical, but differently coloured, tunnels.

Role of the Metal-Oxide Work Function on Photocurrent Generation in Hybrid Solar Cells.

ZnO is a widely used metal-oxide semiconductor for photovoltaic application. In solar cell heterostructures they not only serve as a charge selective contact, but also act as electron acceptor. Although ZnO offers a suitable interface for exciton dissociation, charge separation efficiencies have stayed rather poor and conceptual differences to organic acceptors are rarely investigated.

The transcriptional coregulator MAML1 affects DNA methylation and gene expression patterns in human embryonic kidney cells.

Mastermind-like 1 (MAML1) is a transcriptional coregulator that has been associated with early development of many systems such as neuronal, muscular and urogenital. The present study aimed to explore the genome wide effects of MAML1 on DNA methylation and RNA expression in human embryonic kidney cells. Infinium HumanMethylation450 BeadChip Illumina array, methylation-sensitive high-resolution melt technique, Chip Analysis Methylation Pipeline and RNA profiling approaches were used to study MAML1 effects on the epigenome.

MS-HRM assay identifies high levels of epigenetic heterogeneity in human immortalized cell lines.

Immortalized cell lines are widely used in genetic and epigenetic studies, from exploration of basic molecular pathways to evaluation of disease-specific cellular properties. They are also used in biotechnology, e.g.

Arsenic-induced suppression of kidney cell proliferation and the transcriptional coregulator MAML1.

Mastermind-like 1 (MAML1) is a transcriptional coregulator of diverse/multiple activators, such as Notch, p53, myocyte enhancer factor 2C, NF-κB, beta-catenin, papillomavirus E6 proteins, early growth response 1 and runt-related transcription factor 2. Thus, MAML1 functions in various signaling pathways, most of them connected to cell proliferation, which suggests that MAML1 might play a potential role as a cell proliferation marker. In this study we show that MAML1 expression in the kidney correlates in silico with established cell proliferation markers including PCNA, CDC2 and XRCC5 (Ku80).
