Rhythmic Cycles

The rhythmic theory developed by al-Fārābī remains relevant to the analysis of sung poetry in the contemporary Middle East, not least with respect to the question of how duration comes to be determined and the conception of verse as a constituent of melody (Arabic laḥn) in the fullest sense. This chapter reviews some of Fārābī’s concepts in relation to Christopher Hasty’s discussion of projective potential. Analysis of eight examples of sung verse in Persian and Khorasani Turkish focuses on coordination of tunes with rhythmic cycles associated with different types of poetic meter. I argue that the best analytical work on Persian traditional music, notably that of Dariush Talā’i, provides an excellent foundation for studies of Iran’s regional musics.

Camp Levels

Smooth muscle of the gut undergoes rhythmic cycles of contraction and relaxation. Various constituents in the pathways that mediate muscle contraction could act to cross-regulate cAMP or cGMP levels and terminate subsequent relaxation. We have previously shown that cAMP levels are regulated by PKA-mediated phosphorylation of cAMP-specific phosphodiesterase 3A (PDE3A) and PDE4D5; the latter is the only PDE4D isoform expressed in smooth muscle. In the present study we have elucidated a mechanism whereby cholecystokinin (CCK) and, presumably, other contractile agonists capable of activating PKC can cross-regulate cAMP levels. Forskolin stimulated PDE4D5 phosphorylation and PDE4D5 activity. CCK significantly increased forskolin-stimulated PDE4D5 phosphorylation and activity and attenuated forskolin-stimulated cAMP levels. The effect of CCK on forskolin-induced PDE4D5 phosphorylation and activity and on cAMP levels was blocked by the inhibitors of PLC or PKC and in cultured muscle cells by the expression of Gαq minigene. The effects of CCK on PDE4D5 phosphorylation, PDE4D5 activity, and cAMP levels were mimicked by low (1 nM) concentrations of okadaic acid, but not by a low (10 nM) concentration of tautomycin, suggesting involvement of PP2A. Purified catalytic subunit of PP2A but not PP1 dephosphorylated PDE4D5 in vitro. Coimmunoprecipitation studies demonstrated association of PDE4D5 with PP2A and the association was decreased by the activation of PKC. In conclusion, cAMP levels are cross-regulated by contractile agonists via a mechanism that involves PLC-β-dependent, PKC-mediated inhibition of PP2A activity that leads to increase in PDE4D5 phosphorylation and activity and inhibition of cAMP levels.

Thirteen writershave comprehensively explained theRenaissance scheme of physiology-psychology used for nosce teipsum, to ‘know oneself’, and other scholars have analysed key features likehumours, bodily spirits, passions, reason, inner wits, soul and spirit, mystic apprehension.Only poetswith epic scope, like Spenser and Shakespeare, depict human nature holistically, yet these finest poets have radically distinct psychologies.Spenser’s Christianised Platonism prioritises the soul, his art mirroringdivine Creation as dogmatically and encyclopedically conceived. He looks to the past, collating classical and medieval authorities in memory-devices like the figurative house, nobly ordered in triadic mystic numerical hierarchyto reform the ruins of time. Shakespeare’s sophisticated Aristoteleanism prioritises the body, highlighting physical processes and dynamic feelings of immediate experience, and subjecting them to intense, skeptical consciousness. He points to the future, using the witty ironies of popular stage productions to test and deconstruct prior authority, opening the unconscious to psychoanalysis. This polarity of psychologies is radical and profound, resembling the complementary theories of physics, structuring reality either (like Spenser) in the neatly-contained form of particle theory, or (like Shakespeare) in the rhythmic cycles of wave theory. How do we explain these distinct concepts, and how are they related? These poets’ contrary artistry appears in strikingly different versions of a ‘fairy queen’, of humour-based passions (notably the primal passion of self-love), of intellection (divergent modes of temptation and of moral resolution), of immortal soul and spirit, of holistic plot design, and of readiness for final judgment.

SummaryA case is described where phototherapy rapidly restored sleep-wake disturbances and concurrent symptoms of delirium in a patient who did not respond to conventional treatment with haloperidol. In this case, the delirious state may have been caused by a change in metabolism as a result of sepsis. Exposition of the patient to 8,000 Lux during 1.5 h for 5 consecutive days was sufficient to suppress all delirious symptoms and to normalize sleep. This result may encourage the setup of systematic studies towards the extent of desynchronization between various rhythmic cycles in delirium and towards the value of phototherapy for the restoration of normal circadian rhythmicity.

Chronotherapy refers to the use of circadian, ultradian, infradian and seasonal or other rhythmic cycles in the application of therapy. There are number of conditions which show a circadian pattern and advantage could be taken by timing and adjusting the administration of drugs according to the circadian rhythm of the disease. Some of the conditions, which may be significantly benefited, are hypertension, myocardial infarction, bronchial asthma, peptic ulcer, arthritis, duodenal ulcer, diabetes, neurological disorder, cancer and hypercholesterolemia. Chronotherapy can be classified into time controlled systems wherein the drug release is controlled primarily by the delivery system, stimuli induced PDDS in which release is controlled by the stimuli, such as the pH or enzymes present in the intestinal tract or enzymes present in the drug delivery system and externally regulated system where release is programmed by external stimuli like magnetism, ultrasound, electrical effect and irradiation.

Rhythmic Cycles

In both Persian and Turkish art-music traditions, despite their significant current differences, the musical idiom of the 15th-century Timurid court is regarded as a significant forbear. Late 15th-century theoretical literature, however, refers to regional variations across the Middle East; these were exacerbated by a lack of continuity in Safavid and Ottoman court patronage during the 16th century, resulting in loss of repertoire and eventual replacement. Yet in the late 17th century commonalities between Safavid and Ottoman art-music practices re-emerge. Although not identical, indeed partly divergent, these practices share a core of frequently used modes and rhythmic cycles and use the same structures for complex song-settings; they even have elements of vocal repertoire in common, while certain Ottoman instrumental pieces are labelled ‘Persian’. There is evidence for the maintenance in both traditions of aesthetic constants in the domains of modulatory practice and formal articulation that can be observed much earlier.

Media Learning

Reporting on an ethnographic study of youth media production at an action sports camp, this article describes the symbiotic learning partnerships formed between teen skateboarders and teen videographers necessary to collaboratively demonstrate the mastery of both tricks and video capture/editing. Symbiotic learning partnerships emerge when partners are, as one participant says, vibing with one another: when they are deeply invested in the production of a collaborative media artifact that they will jointly distribute across social media. When vibing with one another, skaters and videographers fall into collaborative, rhythmic cycles. This collaborative mastery is illustrated specifically through a focus on the cycles of reflection and nurture that skaters and videographers enter into when honing their respective crafts. This article advances understanding of youth digital media production in the rich, yet understudied, action sports community, drawing out potential implications for the design of digital media learning settings, broadly, that do not urge youth down individual pathways, but instead implement opportunities for symbiotic participation and learning.

Parietal Cortices

ABSTRACTSpatial attention is discontinuous, sampling behaviorally relevant locations in theta-rhythmic cycles (3–6 Hz). Underlying this rhythmic sampling are intrinsic theta oscillations in frontal and parietal cortices that provide a clocking mechanism for two alternating attentional states that are associated with either engagement at the presently attended location (and enhanced perceptual sensitivity) or disengagement (and diminished perceptual sensitivity). It has remained unclear, however, how these theta-dependent states are coordinated across the large-scale network that directs spatial attention. The pulvinar is a candidate for such coordination, having been previously shown to regulate cortical activity. We therefore examined pulvino-cortical interactions during theta-rhythmic sampling by simultaneously recording from FEF, LIP, and the pulvinar. Neural activity propagated from (i) pulvinar to cortex during periods of engagement and (ii) from cortex to pulvinar during periods of disengagement. A rhythmic reweighting of pulvino-cortical interactions thus defines functional dissociations in the macaque attention network.
