This article explores the poetic metaphors and multi-signification in Chinua Achebe’s No Longer at Ease . The novel itself has been the focus of several readings, many of which pursue the humanistic and sociological orientations of the text as merely an instrument of communication about the post-independence sociopolitical and cultural realities of Achebe’s society. This manner of reading may be attributed to the birth of African literature and Afrocentrism, which many of the earlier writers, including Achebe, believe was a reaction to the poor Euro-American portrayal of Africa and Africans. But it forecloses the possibility of a grounded analytical methodology capable of opening up multiple possibilities of meanings in the text through the linguistic elements of literature. Relying on Paul Ricoeur’s depth semantic theory, this article explores the poetic metaphors of the text to unveil the multilayered meanings.

Coordinated rhythmic movements are ubiquitous in animal behavior. In many organisms, chains of neural oscillators underlie the generation of these rhythms. In C. elegans, locomotor wave generation has been poorly understood; in particular, it is unclear where in the circuit rhythms are generated, and whether there exists more than one such generator. We used optogenetic and ablation experiments to probe the nature of rhythm generation in the locomotor circuit. We found that multiple sections of forward locomotor circuitry are capable of independently generating rhythms. By perturbing different components of the motor circuit, we localize the source of secondary rhythms to cholinergic motor neurons in the midbody. Using rhythmic optogenetic perturbation, we demonstrate bidirectional entrainment of oscillations between different body regions. These results show that, as in many other vertebrates and invertebrates, the C. elegans motor circuit contains multiple oscillators that coordinate activity to generate behavior.

In this essay, I use the song 'Let It Go' from Frozen as a steppingstone for addressing song and animated musical film as combined media, or rather integrations, and, based on the models put forward by Lars Ellestrom, propose a framework for discussing different kinds of synchronic intermediality. I propose that when analysing synchronic intermediality, we need to consider (at least) three types of combination: 1) combination of modalities (understood as formal structures framing the content), 2) combination of qualified aspects (understood as conventions of media products, herein those aspects tied to media representation), and 3) combination of semiotic content. Keywords: intermediality, song, musical, combination, Frozen

Background The receptor-like kinase FEROINA (FER) plays a crucial role in controlling plant vegetative growth partially by sensing the rapid alkalinization factor (RALF) peptide. However, the role of RALF1-FER in the vegetative-reproductive growth transition remains unknown. Here, we analyze the mechanism through which FER affects the flowering time in Arabidopsis. Results We found that the FER mRNA levels exhibit an oscillating pattern with a diurnal rhythm and that the clock oscillator CIRCADIAN CLOCK-ASSOCIATED1 ( CCA1 ) up-regulates the expression of FER by associating with its chromatin. In addition, FER expression is regulated by clock genes, and FER also modulates the expression patterns of clock genes. Consistent with its gene expression pattern, FER positively regulates flowering by modulating the transcript accumulation and mRNA alternative splicing of certain flowering-related genes, including FLOWERING LOCUS C (FLC) and its homolog MADS AFFECTING FLOWERING (MAF) . However, the RALF1 ligand negatively regulates flowering compared with FER. Conclusions We found that FER, which is up-regulated by CCA1, controls the flowering time by regulating the transcript accumulation and mRNA alternative splicing (AS) of some important flowering genes, and these findings link FER to the floral transition.

Atrial fibrillation (AF) is the most common form of cardiac arrhythmia and significantly increases the risks of morbidity, mortality and health care expenditure; however, treatment for AF remains unsatisfactory due to the complicated and incompletely understood underlying mechanisms. In the present study, weighted gene co-expression network analysis (WGCNA) was conducted to identify key modules and hub genes to determine their potential associations with AF. WGCNA was performed in an AF dataset GSE79768 obtained from the Gene Expression Omnibus, which contained data from paired left and right atria in cardiac patients with persistent AF or sinus rhythm. Differentially expressed gene (DEG) analysis was used to supplement and validate the results of WGCNA. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were also performed. Green and magenta modules were identified as the most critical modules associated with AF, from which 6 hub genes, acetyl-CoA Acetyltransferase 1, death domain-containing protein CRADD, gypsy retrotransposon integrase 1, FTX transcript, XIST regulator, transcription elongation factor A like 2 and minichromosome maintenance complex component 3 associated protein, were hypothesized to serve key roles in the pathophysiology of AF due to their increased intramodular connectivity. Functional enrichment analysis results demonstrated that the green module was associated with energy metabolism, and the magenta module may be associated with the Hippo pathway and contain multiple interactive pathways associated with apoptosis and inflammation. In addition, the blue module was identified to be an important regulatory module in AF with a higher specificity for the left atria, the genes of which were primarily correlated with complement, coagulation and extracellular matrix formation. These results suggest that may improve understanding of the underlying mechanisms of AF, and assist in identifying biomarkers and potential therapeutic targets for treating patients with AF.

Art is the most aesthetic creation produced by humankind, and it is quite unthinkable that art should exist independently of religion. Even in works of a profane nature, a sense of divinity can still be felt at some level. In the revealed religions—Judaism, Christianity, and Islam—the teachings of the sacred scriptures, intermingled with certain pagan beliefs, have a profound influence on the shaping of art. In the works of the fourteenth century, when Classical Turkish literature began to flourish in Anatolia, numerous Christian elements appear in the form of metaphors, allusions, or similes. The early period of intense interaction with the Orthodox Byzantine Empire, the proliferation of written literary texts, the introduction of the devşirme (child-levy) system, Ottoman settlements in Rumelia, and the expanding military, commercial, and social relations all accelerated the entry of Christian motifs into daily life and literature. This article examines how Christianity—the religion with the largest number of adherents today—was reflected in fourteenth-century Turkish literary texts and how it influenced the cultural life of the period.

Laypersons' efforts to initiate basic life support (BLS) in witnessed Out-of-Hospital Cardiac Arrest (OHCA) remain comparably low within western society. Therefore, in order to shorten no-flow times in cardiac arrest, several police-based first responder systems equipped with automated external defibrillators (Pol-AED) were established in urban areas, which subsequently allow early BLS and AED administration by police officers. However, data on the quality of BLS and AED use in such a system and its impact on patient outcome remain scarce and inconclusive. A total of 85 Pol-AED cases were randomly assigned to a gender, age and first rhythm matched non-Pol-AED control group (n = 170) in a 1:2 ratio. Data on quality of BLS were extracted via trans-thoracic impedance tracings of used AED devices. Comparing Pol-AED cases and the control group, we observed a similar compression rate per minute (p = 0.677) and compression ratio (p = 0.651), mirroring an overall high quality of BLS administered by police officers. Time to the first shock was significantly shorter in Pol-AED cases (6 minutes [IQR: 2-10] vs. 12 minutes [IQR: 8-17]; p<0.001). While Pol-AED was not associated with increased sustained return of spontaneous circulation (p = 0.564), a strong and independent impact on survival until hospital discharge (adj. OR: 1.85 [95%CI: 1.06-3.23; p = 0.030]) and a borderline significance for the association with favorable neurological outcome (adj. OR: 1.58 [95%CI: 0.96-2.89; p = 0.052) were observed. We were able to demonstrate an early start and a high quality of BLS and AED use in Pol-AED assessed OHCA cases. Moreover, the presence of Pol-AED care was associated with better patient survival and borderline significance for favorable neurological outcome.
