The present study was to further the understanding of the conceptual relationship between narrative absorption, that is the intense engagement with a story world, and felt suspense, that is the anticipation of a narrative outcome event. To this end, a media comparative online experiment was conducted with a 2 (Media format: film vs. Literature) × 2 (Suspense structure: diegetic vs. Non-diegetic delay) × 2 (Stories) between subject design. Results revealed a complex relationship among felt suspense, attention, emotional engagement, and transportation, showing the high importance of attention in felt suspense, and the moderating effect of media format and gender. Findings indicate that non-diegetic suspense delay unlike diegetic suspense decreases felt suspense and narrative absorption independently of media format.

Most film viewers know the experience of being deeply absorbed in the story of a popular film. It seems that at such moments they lose awareness of watching a movie. And yet it is highly unlikely that they completely ignore the fact that they watch a narrative and technological construction. Perhaps film viewers experience being in a story world while simultaneously being aware of its construction. Such a dual awareness would seem paradoxical, because the experience of the one would go at the cost of the other. We argue that the solution of this paradox requires dropping the notion of an undivided consciousness, and replacing it with one of consciousness as coming in degrees. In this chapter we present both cognitive and film-analytic arguments for differential awareness of story and narration/technology, and argue that a characteristic of absorption is to be found in story world super-consciousness.

When reading literary narratives, we assume that readers can get absorbed in the story world and in the story's artifice. Since most absorption research focuses primarily on popular media, virtually no attention has been paid to the possibility that literary devices such as deviation could elicit absorption experiences or that absorption could be aesthetic in nature. This chapter takes an interdisciplinary approach combining insights from media psychology, literary studies, and aesthetics to present a theoretical framework for two different varieties of narrative aesthetic absorption during reading: story world absorption and artifact absorption. We propose that these varieties mirror the distinction made by narratologists between story and discourse and the distinction made by emotion psychologists between F and A emotions.

We have investigated the photoionization and photodissociation of free coronene cations C24H12+ upon soft X-ray photoabsorption in the carbon K-edge region by means of a time-of-flight mass spectrometry approach. Core excitation into an unoccupied molecular orbital (below threshold) and core ionization into the continuum both leave a C 1s vacancy, that is subsequently filled in an Auger-type process. The resulting coronene dications and trications are internally excited and cool down predominantly by means of hydrogen emission. Density functional theory was employed to determine the dissociation energies for subsequent neutral hydrogen loss. A statistical cascade model incorporating these dissociation energies agrees well with the experimentally observed dehydrogenation. For double ionization, i.e., formation of intermediate C24H123+trications, the experimental data hint at loss of H+ ions. This asymmetric fission channel is associated with hot intermediates, whereas colder intermediates predominantly decay via neutral H loss.

Exercise is one of the external factors associated with impairment of intestinal integrity, possibly leading to increased permeability and altered absorption. Here, we aimed to examine to what extent endurance exercise in the glycogen‐depleted state can affect intestinal permeability toward small molecules and protein‐derived peptides in relation to markers of intestinal function. Eleven well‐trained male volunteers (27 ± 4 years) ingested 40 g of casein protein and a lactulose/rhamnose (L/R) solution after an overnight fast in resting conditions (control) and after completing a dual – glycogen depletion and endurance – exercise protocol (first protocol execution). The entire procedure was repeated 1 week later (second protocol execution). Intestinal permeability was measured as L/R ratio in 5 h urine and 1 h plasma. Five‐hour urine excretion of betacasomorphin‐7 (BCM7), postprandial plasma amino acid levels, plasma fatty acid binding protein 2 (FABP‐2), serum pre‐haptoglobin 2 (preHP2), plasma glucagon‐like peptide 2 (GLP2), serum calprotectin, and dipeptidylpeptidase‐4 (DPP4) activity were studied as markers for excretion, intestinal functioning and recovery, inflammation, and BCM7 breakdown activity, respectively. BCM7 levels in urine were increased following the dual exercise protocol, in the first as well as the second protocol execution, whereas 1 h‐plasma L/R ratio was increased only following the first exercise protocol execution. FABP2, preHP2, and GLP2 were not changed after exercise, whereas calprotectin increased. Plasma citrulline levels following casein ingestion (iAUC) did not increase after exercise, as opposed to resting conditions. Endurance exercise in the glycogen depleted state resulted in a clear increase of BCM7 accumulation in urine, independent of DPP4 activity and intestinal permeability. Therefore, strenuous exercise could have an effect on the amount of food‐derived bioactive peptides crossing the epithelial barrier. The health consequence of increased passage needs more in depth studies.

It is clear that the increase in scale that communication technology (colonization) has realized has reduced the number of co-existing realities. Still, the process of increasingly global unification and the subordination and absorption of local diversity is far from easy to understand. The paper focusses on how this works.

From TU Delft repository: "Intestinal transporter proteins and metabolizing enzymes play a crucial role in the oral absorption of a wide variety of drugs. The aim of the current study was to characterize better available intestinal in vitro models by comparing expression levels of these proteins and enzymes between porcine intestine, human intestine, and Caco-2 cells. We therefore determined the absolute protein expression of 19 drug transporters and the mRNA expression of 12 metabolic enzymes along the pig intestinal tract (duodenum, jejunum, ileum; N = 4), in human intestine (jejunum; N = 9), and Caco-2 cells. Expression of the included transporters and enzymes was in general well comparable between porcine and human intestinal tissue, although breast cancer resistance protein, monocarboxylate transporter 5, multidrug resistance protein (MRP) 1,MRP1,MRP3 (∼2-fold), and organic anion-transporting polypeptide (OATP) 4A1 (∼6-fold) was higher expressed in pig compared with human jejunum. Alternatively, expression level of relevant transporter proteins (glucose transporter 1, OATP4A1, MRP2, MRP1, and OATP2B1) was significantly higher (3- to 130-fold) in Caco-2 cells compared with human jejunum. Moreover, all examined CYPs showed at least a fivefold lower gene expression in Caco-2 cells compared with human jejunum, with the smallest differences for CYP1A1 and CYP3A5 and the largest difference for CYP3A4 (871-fold higher expression in human jejunum compared with Caco-2 cells). In conclusion, a comprehensive overview is provided of the expression levels of clinically relevant transporter proteins and metabolic enzymes in porcine and human intestinal tissue and Caco-2 cells, which may assist in deciding upon the most suitable model to further improve our understanding of processes that determine intestinal absorption of compounds." https://repository.tudelft.nl/view/tno/uuid%3A48bafffb-6f20-4569-a343-7edf003ca058

The chromatographic behavior of petanin, petunidin-3-O-[6-O-(4-O-(E)-para-coumaroyl-O-α-rhamnopyranosyl)-β-glucopyranoside]-5-O-β-glucopyranoside, is studied for the first time under conditions of reversed-phase high performance liquid chromatography in mobile phases with different pH values. The relationship between chromatographic behavior (retention time and peak efficiency) and transitions between different forms of anthocyanins is discussed. Analysis of the data obtained in the 2 to 6.5 range of mobile pH phases, the absorption spectra of petanin, and the results from studying the effect of adding tetrabutylammonium bromide to the mobile phase shows that increasing the pH results in the formation of uncharged and anionic forms, in addition to the pseudobase form.
