Dogs have remarkable abilities to synergise their behaviour with that of people, but how dogs read facial and bodily emotional cues in comparison to humans remains unclear. Both species share the same ecological niche, are highly social and expressive, making them an ideal comparative model for intra- and inter-species emotion perception. We compared eye-tracking data from unrestrained humans and dogs when viewing dynamic and naturalistic emotional expressions in humans and dogs. Dogs attended more to the body than the head of human and dog figures, unlike humans who focused more on the head of both species. Dogs and humans also showed a clear age effect that reduced head gaze. Our results indicate a species-specific evolutionary adaptation for emotion perception, which is only partly modified for heterospecific cues. These results have important implications for managing the risk associated with human-dog interactions, where expressive and perceptual differences are crucial.

The dormancy release in Avena fatua caryopses was associated with a reduction in the ABA content in embryos, coleorhiza and radicle. The coleorhiza proved more sensitive to KAR

and less sensitive to ABA than the radicle. The inability of dormant caryopses and ABA-treated non-dormant caryopses to complete germination is related to inhibition and delayed of cell-cycle activation, respectively. As freshly harvested Avena fatua caryopses are dormant at 20°C, they cannot complete germination; the radicle is not able to emerge. Both karrikin 1 (KAR

) and dry after-ripening release dormancy, enabling the emergence of, first, the coleorhiza and later the radicle. The after-ripening removes caryopse sensitivity to KAR

and decreases the sensitivity to abscisic acid (ABA). The coleorhiza was found to be more sensitive to KAR

, and less sensitive to ABA, than radicles. Effects of KAR

and after-ripening were associated with a reduction of the embryo's ABA content during caryopsis germination. KAR

was found to later the radicle. The after-ripening removes caryopse sensitivity to KAR1 and decreases the sensitivity to abscisic acid (ABA). The coleorhiza was found to be more sensitive to KAR1, and less sensitive to ABA, than radicles. Effects of KAR1 and after-ripening were associated with a reduction of the embryo's ABA content during caryopsis germination. KAR1 was found to decrease the ABA content in the coleorhiza and radicles. Germination of after-ripened caryopses was associated with the progress of cell-cycle activation before coleorhiza emergence. Inhibition of the germination completion due to dormancy or treating the non-dormant caryopses with ABA was associated with a total and partial inhibition of cell-cycle activation, respectively.Taking the reporting donor SM0 as reference, three new A-π-D-π-A type small molecules donors (SM1, SM2, and SM3) were designed via replacing acceptor moieties. The molecular proprieties affecting the cell performance, such as, frontier molecular orbital, open circuit voltage (Voc), absorption spectrum, vertical and adiabatic ionization potential, vertical and adiabatic electronic affinity, and energy driving force ΔEL-L were investigated through the density functional theory (DFT) and the time dependent density functional theory (TD-DFT). All new designed molecules exhibit reduced energy gap, show a red shift absorption band, small energy binding Eb, moderate Voc, and improve the creation of hole and electron as compared to SM0, which demonstrate that these new designed molecules could be used as a promising donors materials for organic solar cell. Additionally, the three new designed molecules present a larger amount charge transfer qCT, a longer length charge transfer DCT than SM0 and have a smaller reorganization energy of hole λ(h) which improve the charge carrier mobilities.L-6-Hydroxynicotine oxidase (LHNO) is a member of monoamine oxidase (MAO) family and catalyzes conversion of (S)-6-hydroxynicotine to 6-hydroxypseudooxynicotine during bacterial degradation of nicotine. Recent studies indicated that the enzyme catalyzes oxidation of carbon-nitrogen bond instead of previously proposed carbon-carbon bond. Based on kinetics and mutagenesis studies, Asn166, Tyr311, and Lys287 as well as an active site water molecule have roles in the catalysis of the enzyme. A number of studies including experimental and computational methods support hydride transfer mechanism in MAO family as a common mechanism in which a hydride ion transfer from amine substrate to flavin cofactor is the rate-limiting step. In this study, we formulated computational models to study the hydride transfer mechanism using crystal structure of enzyme-substrate complex. The calculations involved ONIOM and DFT methods, and we evaluated the geometry and energetics of the hydride transfer process while probing the roles of active site residues. Based on the calculations involving hydride, radical, and polar mechanisms, it was concluded that hydride transfer mechanism is the only viable mechanism for LHNO.

To introduce sub-adventitial divestment technique (SDT), a procedure to remove the tumor while preserving the artery during curative pancreatectomy. Peri-operative safety profile was also evaluated.

In a single center consecutive series of pancreatectomy for pancreatic cancer, the outcome of patients who had pancreatectomy with SDT was compared to standard pancreatic surgery.

From June 2014 to June 2016, 72 patients had pancreatectomy with SDT and 235 had standard surgery. Tumor stage was T4 in all 72 (100%) tumors removed using SDT compared to four (2%) with standard pancreatectomy (p < 0.001). All 72 (100%) tumors in the SDT group were stage III compared to 24 (10%) in the standard surgery group (p < 0.001). selleckchem Both groups had a high proportion of poorly differentiated tumors (52 (72%) and 163 (69%) respectively) and perineural tumor invasion (62 (86%) and 186 (79%) respectively). R1 (< 1mm) was found in 24 (86%) of 28 tumors in the SDT group, and in 72 (60%) out of 120 standard pancreatectomy tumors (p = 0.01). Complications occurred in 29 (40%) of the SDT group and in 88 (37%) of the standard group. The in-hospital mortality was four (6%) in the SDT group and one (0.4%) in the standard group (p = 0.01), with a 90-day mortality of 5 (8%)/60 and 6 (3%)/209 (p = 0.07) respectively.

The sub-adventitial divestment technique appeared to be an effective surgical technique to remove the tumor while preserving the artery. This approach warrants further validation in prospective studies.
