Four Discourses ◽

The Universe

Eberhard the German’s Laborintus is one of the artes poetriae that has been influenced by Geoffrey de Vinsauf’s Poetria nova. In line with Greoffrey de Vinsauf’s teaching on prosopopoeia, i.e. one of the most important figures that an author must use, in the first 252 lines of his Laborintus Eberhard the German introduces at least four discourses in which Nature, Fate/Fortune, Philosophy and Grammar expose and argue their importance in man’s life. The analysis of both the reasons and actions and the form in which they are exposed (elocution) contains the author’s vision of the universe and opposes positive and negative things (res), which are represented by rhetorical elements such as docere, commovere and persuadere. Such elements can define the essential role the knowledge of grammar, rhetoric and philosophy plays in the education and salvation of men.

The Universe

Cosmologists regularly generate synthetic universes of galaxies using computer simulations. Such catalogues have an essential role to play in the analysis and exploitation of current and forthcoming galaxy surveys. I review the different ways in which synthetic or ‘mock’ catalogues are produced and discuss the different physical processes that the models attempt to follow, explaining why it is important to be as realistic as possible when trying to forge the Universe.

Adult Thymus

T cells recognize the universe of foreign antigens with a diverse repertoire of T cell receptors generated by V (D)J recombination. Special AT-rich binding protein 1 (Satb1) is a chromatin organizer that plays an essential role in T cell development. The previous study showed that Satb1 regulates the re-induction of recombinase Rag1 and Rag2 in CD4+CD8+ thymocytes, affecting the secondary rearrangement of the Tcra gene. Here, we detected the repertoires of four TCR genes, Tcrd, Tcrg, Tcrb, and Tcra in the adult thymus, and explored the role of the Satb1 in shaping the TCR repertoires. We observed a strong bias in the V and J gene usages of the Tcrd and Tcrg repertoires in WT and Satb1-deleted thymocytes. Satb1 deletion had few effects on the V(D)J rearrangement and repertoire of the Tcrg, Tcrd, and Tcrb genes. The Tcra repertoire was severely impaired in Satb1-deleted thymocytes, while the primary rearrangement was relatively normal. We also found the CDR3 length of TCRα chain was significantly longer in Satb1-deleted thymocytes, which can be explained by the strong bias of the proximal Jα usage. Our results showed that Satb1 plays an essential role in shaping TCR repertoires in αβ T cells.

The Universe

Henry David’s Thoreau book Walden recreates in a literary form the period that the author spent in the woods near Walden Pond. Being a transcendentalist influenced by Emerson’s philosophy, Thoreau reiterates the essential role that nature has in the spiritual and moral development of man. In Walden the author describes a return to a primordial age in which man lived in a state of wonder before the beauty of the universe and in a permanent communion with it. The sacredness of nature is rendered through ritual gestures that accompany man on his road to revelation. Thus, the period of time spent by Thoreau near Walden Pond acquires the qualities of an initiation during which man rediscovers his self and undergoes a spiritual awakening.

Hα Emission

AbstractThe relation between episodically observed in the solar corona faint Hαemission structures and the long lived prominences was studied. Particular consideration was given for cases in which the corresponding prominences had undergone DB process. An MHD interpretation of the phenomenon “emissions froides” (cool emission) is proposed in which an essential role plays the prominence supporting magnetic field.

Boar Spermatozoa

It is believed that i ntramembra.nous sterols play an essential role in membrane stability and permeability. To investigate the distribution changes of sterols in sperm membrane during epididymal maturation and capacitation, filipin has been used as a cytochemical probe for the detection for membrane sterols. Using this technique in combination with freeze fracturing, we examined the boar spermatozoa under various physiological conditions.The spermatozoa were collected from: 1) caput, corpus and cauda epididymides, 2) sperm rich fraction of ejaculates, and 3)the uterus 2hr after natural coition. They were fixed with 2.5% glutaraldehyde in 0.05M cacodylate buffer (pH 7.4), and treated with the filipin solution (final concentration : 0.02.0.05%) for 24hr at 4°C with constant agitation. After the filipin treatment, replicas were made by conventional freeze-fracture technique. The density of filipin-sterol complexes (FSCs) was determined in the E face of the plasma membrane of head regions.
