An arrow marker appearing in a field of view shifts the observer's attention in its indicated direction. On the other hand, the gaze of another individual not only shifts the observer's attention but also increases the likability of objects in the direction of their gaze. These effects occur even when the arrow markers or gaze cues are presented for very short periods so that the observer is unaware of them. To expand on the findings of previous studies, we conducted two experiments. In the first we examined the changes in likability and attentional shift induced by supraliminal and subliminal arrow markers, using 40 male and 40 female participants. We found, contrary to previous findings, that supraliminal arrow markers not only shifted the observers' attention but slightly increased object likability. On the other hand, subliminal arrow markers only shifted the observers' attention. The attentional shift was stronger for female than for male participants in the case of supraliminal, but not of subliminal, markers. The second experiment verified the changes in likability induced by supraliminal arrow markers and compared the effects with those of supraliminal gaze cues among 40 female participants. We found that the liking effect was observed for both arrow markers and gaze cues. However, both effects were small, and no significant difference was found between them. Overall, these results show that gender and individual differences have considerable impacts on cueing effects.

We present a rare case of rhabdoid squamous cell carcinoma (RSCC) on the scalp of a non-immunosuppressed male patient in his late 60s. This aggressive variant of squamous cell carcinoma (SCC) is characterized by tumor cells with eccentrically located nuclei and abundant eosinophilic cytoplasm, as observed on histopathological examination. While rhabdoid morphology has been reported in various anatomical sites, its occurrence in primary cutaneous tumors is exceptionally uncommon, with fewer than 10 cases documented to date.

We hypothesized that the level of non-equilibrium can serve as a signature of a given brain state, which was quantified using the arrow of time (the level of irreversibility). Using this thermodynamic framework, the irreversibility of emergent cortical activity was quantified from local field potential recordings in male Lister-hooded rats at different anesthesia levels and during the sleep-wake cycle.

Article Synopsis
- * An experimental setup involving 39 participants in a driving simulator generated data revealing impaired driving performance in these sections and highlighted key variables affecting traffic control devices.
- * Recommendations include removing certain guide signs, replacing them with arrow markers, and adding distance signs to improve driver awareness and enhance safety in tunnel-exit areas.

Article Synopsis
- The leaves of Yerba mate display various biological activities, including effects against obesity and certain cancers, and possess antimicrobial and antiviral properties.
- The study analyzed the chemical composition of two European species of Yerba mate, identifying 86 compounds with notable constituents in terpenoid and saponin fractions, and revealed similarities in volatile profiles between European and South American species.
- The research highlighted that saponins, particularly from the Silver Queen variety, showed significant inhibition of cancer cell growth and antiviral activity, suggesting the potential for new antiviral treatments derived from European holly.
