Epigenetics: Connecting Environment and Genotype to Phenotype and Disease
Creators: name: Barros, S.P.
name: Offenbacher, S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Genetic information is encoded not only by the linear sequence of DNA, but also by epigenetic modifications of chromatin structure that include DNA methylation and covalent modifications of the proteins that bind DNA. These “epigenetic marks” alter the structure of chromatin to influence gene expression. Methylation occurs naturally on cytosine bases at CpG sequences and is involved in controlling the correct expression of genes. DNA methylation is usually associated with triggering histone deacetylation, chromatin condensation, and gene silencing. Differentially methylated cytosines give rise to distinct patterns specific for each tissue type and disease state. Such methylation-variable positions (MVPs) are not uniformly distributed throughout our genome, but are concentrated among genes that regulate transcription, growth, metabolism, differentiation, and oncogenesis. Alterations in MVP methylation status create epigenetic patterns that appear to regulate gene expression profiles during cell differentiation, growth, and development, as well as in cancer. Environmental stressors including toxins, as well as microbial and viral exposures, can change epigenetic patterns and thereby effect changes in gene activation and cell phenotype. Since DNA methylation is often retained following cell division, altered MVP patterns in tissues can accumulate over time and can lead to persistent alterations in steady-state cellular metabolism, responses to stimuli, or the retention of an abnormal phenotype, reflecting a molecular consequence of gene-environment interaction. Hence, DNA epigenetics constitutes the main and previously missing link among genetics, disease, and the environment. The challenge in oral biology will be to understand the mechanisms that modify MVPs in oral tissues and to identify those epigenetic patterns that modify disease pathogenesis or responses to therapy.

description: We consider $m$-divisible non-crossing partitions of $\{1,2,\ldots,mn\}$ with the property that for some $t\leq n$ no block contains more than one of the first $t$ integers. We give a closed formula for the number of multi-chains of such non-crossing partitions with prescribed number of blocks. Building on this result, we compute Chapoton's $M$-triangle in this setting and conjecture a combinatorial interpretation for the $H$-triangle. This conjecture is proved for $m=1$.

description: Despite the prevalence of craniofacial disorders, the genetic contribution remains poorly understood. Class III malocclusion represents a specific craniofacial problem that can be handicapping, both functionally and socially. We hypothesized that the Class III phenotype is genetically linked to specific loci that regulate maxillary or mandibular growth. To determine the region linked to the Class III phenotype in four Hispanic families, we performed a genome-wide scan and linkage analysis using 500 microsatellite markers. Pedigree and linkage analyses revealed that the Class III phenotype (primarily maxillary deficiency) segregates in an autosomal-dominant manner, and that 5 loci (1p22.1, 3q26.2, 11q22, 12q13.13, and 12q23) are suggestive of linkage. Candidate genes within the 12q23 region (ZLR = 2.93) include IGF1, HOXC, and COL2A1. Chromosome 1 results (ZLR = 2.92) were similar to those reported previously in an Asian cohort with mandibular prognathism, suggesting that a common upstream genetic element may be responsible for both mandibular prognathism and maxillary deficiency.

description: Asteroseismic binaries are defined as single light curves including two oscillation patterns. Predictions indicate that approximately 200 red-giant asteroseismic binaries could be present among the roughly 20,000 red giants observed by Kepler. However, detecting such systems becomes particularly challenging when the binaries exhibit overlapping oscillation spectra. To address this challenge, we created thousands of synthetic asteroseismic binaries by combining the KASOC light curves of two individual red giants. We investigated how their oscillation modes interact and superpose when including stars with different evolutionary stages, brightness, and frequency at maximum oscillation power (𝜈_max). We then categorised these synthetic complex power spectra to identify unique characteristics, such as entangled shapes of non-radial modes, irregular oscillation behaviours, and intricate mode interactions. We discuss a deeper understanding of the nature and detectability of asteroseismic binaries with complex features, offering insights into stars that were so far not understood.

description: We characterize the modules of infinite projective dimension over the endomorphism algebras of Opperman-Thomas cluster tilting objects $X$ in $(n+2)$-angulated categories $(\mathcal C,Σ^n,Θ)$. For an indecomposable object $M$ of $\mathcal C$, we define in this article the ideal $I_M$ of ${\rm End}_{\mathcal C}(Σ^nX)$ given by all endomorphisms that factor through ${\rm add} M$, and show that the ${\rm End}_{\mathcal C}(X)$-module ${\rm Hom}_{\mathcal C}(X,M)$ has infinite projective dimension precisely when $I_M$ is non-zero. As an application, we generalize a recent result by Beaudet-Brüstle-Todorov for cluster-tilted algebras.

description: We explore the influence of turbulence on the transport of energetic particles by using test-particle simulations. We compute parallel and perpendicular diffusion coefficients for two-component turbulence, isotropic turbulence, a model based on Goldreich-Sridhar scaling, noisy reduced magnetohydrodynamic turbulence, and a noisy slab model. We show that diffusion coefficients have a similar rigidity dependence regardless which turbulence model is used and, thus, we conclude that the influence of turbulence on particle transport is not as strong as originally thought. Only fundamental quantities such as particle rigidity and the Kubo number are relevant. In the current paper we also confirm the unified nonlinear transport theory for noisy slab turbulence. To double-check the validity and accuracy of our numerical results, we use a second test-particle code. We show that both codes provide very similar results confirming the validity of our conclusions.

description: FAM83H gene mutations are associated with autosomal-dominant hypocalcified amelogenesis imperfecta (ADHCAI), which is typically characterized by enamel having normal thickness and a markedly decreased mineral content. This study tested the hypothesis that there are phenotype and genotype associations in families with FAM83H-associated ADHCAI. Seven families segregating ADHCAI (147 individuals) were evaluated. Phenotyping included clinical, radiographic, histological, and biochemical studies, and genotyping was by mutational analysis. Multiple novel FAM83H mutations were identified, including two 2-bp-deletion mutations, the first non-nonsense mutations identified. Craniofacial deviation from normal was more prevalent in the affected individuals. Affected individuals having truncating FAMH3H mutations of 677 or fewer amino acids presented a generalized ADHCAI phenotype, while those having mutations capable of producing a protein of at least 694 amino acids had a unique and previously unreported phenotype affecting primarily the cervical enamel. This investigation shows that unique phenotypes are associated with specific FAM83H mutations.

description: Threshold models of global cascades have been extensively used to model real-world collective behavior, such as the contagious spread of fads and the adoption of new technologies. A common property of those cascade models is that a vanishingly small seed fraction can spread to a finite fraction of an infinitely large network through local infections. In social and economic networks, however, individuals' behavior is often influenced not only by what their direct neighbors are doing, but also by what the majority of people are doing as a trend. A trend affects individuals' behavior while individuals' behavior creates a trend. To analyze such a complex interplay between local- and global-scale phenomena, I generalize the standard threshold model by introducing a new type of node, called \textit{global nodes} (or \textit{trend followers}), whose activation probability depends on a global-scale trend; specifically the percentage of activated nodes in the population. The model shows that global nodes play a role as accelerating cascades once a trend emerges while reducing the probability of a trend emerging. Global nodes thus either facilitate or inhibit cascades, suggesting that a moderate share of trend followers may maximize the average size of cascades.

description: For the spherical Laplacian on the sphere and for the Dirichlet Laplacian in the square}, Antonie Stern claimed in her PhD thesis (1924) the existence of an infinite sequence of eigenvalues whose corresponding eigenspaces contain an eigenfunction with exactly two nodal domains. These results were given complete proofs respectively by Hans Lewy in 1977, and the authors in 2014 (see also Gauthier-Shalom--Przybytkowski, 2006). In this paper, we obtain similar results for the two dimensional isotropic quantum harmonic oscillator. In the opposite direction, we construct an infinite sequence of regular eigenfunctions with as many nodal domains as allowed by Courant's theorem, up to a factor $\frac{1}{4}$. A classical question for a $2$-dimensional bounded domain is to estimate the length of the nodal set of a Dirichlet eigenfunction in terms of the square root of the energy. In the last section, we consider some Schr{ö}dinger operators $-Δ+ V$ in $\mathbb{R}^2$ and we provide bounds for the length of the nodal set of an eigenfunction with energy $λ$ in the classically permitted region $\{V(x) < λ\}$.

description: According to the Circle Packing Theorem, any triangulation of the Riemann sphere can be realized as a nerve of a circle packing. Reflections in the dual circles generate a Kleinian group $H$ whose limit set is an Apollonian-like gasket $Λ_H$. We design a surgery that relates $H$ to a rational map $g$ whose Julia set $\mathcal{J}_g$ is (non-quasiconformally) homeomorphic to $Λ_H$. We show for a large class of triangulations, however, the groups of quasisymmetries of $Λ_H$ and $\mathcal{J}_g$ are isomorphic and coincide with the corresponding groups of self-homeomorphisms. Moreover, in the case of $H$, this group is equal to the group of Möbius symmetries of $Λ_H$, which is the semi-direct product of $H$ itself and the group of Möbius symmetries of the underlying circle packing. In the case of the tetrahedral triangulation (when $Λ_ H$ is the classical Apollonian gasket), we give a piecewise affine model for the above actions which is quasiconformally equivalent to $g$ and produces $H$ by a David surgery. We also construct a mating between the group and the map coexisting in the same dynamical plane and show that it can be generated by Schwarz reflections in the deltoid and the inscribed circle.

description: Levels of prostaglandin E2 and the prostaglandin-endoperoxide synthase-2 (PTGS2, or COX-2) increase in actively progressing periodontal lesions, but decrease in chronic disease. We hypothesized that chronic inflammation is associated with altered DNA methylation levels within the PTGS2 promoter, with effects on COX-2 mRNA expression. PTGS2 promoter methylation levels from periodontally inflamed gingival biopsies showed a 5.06-fold increase as compared with non-inflamed samples (p = 0.03), and the odds of methylation in a CpG site in the inflamed gingival group is 4.46 times higher than in the same site in the non-inflamed group (p = 0.016). The level of methylation at −458 bp was inversely associated with transcriptional levels of PTGS2 (RT-PCR) (p = 0.01). Analysis of the data suggests that, in chronically inflamed tissues, there is a hypermethylation pattern of the PTGS2 promoter in association with a lower level of PTGS2 transcription, consistent with a dampening of COX-2 expression in chronic periodontitis. These findings suggest that the chronic persistence of the biofilm and inflammation may be associated with epigenetic changes in local tissues at the biofilm-gingival interface.
Competing Roles of TGFβ and Nma/BAMBI in Odontoblasts

description: Nma/BAMBI is a novel pseudoreceptor with homology to a TGFβ type I receptor that lacks a serine/threonine kinase domain. Nma/BAMBI functions as a dominant-negative protein that regulates reciprocal epithelial-mesenchymal interactions during organogenesis. Therefore, we hypothesized that Nma/BAMBI regulates TGFβ signaling and downstream gene expression during dentinogenesis. To test this hypothesis, we examined the downstream gene expression profiles of major dentin extracellular matrix proteins in response to Nma/BAMBI, and we examined the roles of Nma/BAMBI and TGFβ-1 during dentinogenesis. Overexpression of Nma/BAMBI in the mouse odontoblast-like cell line MD10-A2 down-regulated expression of DSPP by 66% and up-regulated expression of DMP1 four-fold. TGFβ treatment reversed Nma/BAMBI’s negative effect on DSPP expression. Furthermore, we demonstrated that TGFβ negatively regulates Nma/BAMBI’s expression levels in MD10-A2 odontoblast-like cells. Analysis of these data, together, indicates that TGFβ and Nma/BAMBI are inversely regulated and that the sequence of expression determines the net effect on downstream gene expression.

Based on our test particle simulations, we propose a model that leads to an exponential loss of particles.

description: The decision for lip revision surgery in patients with repaired cleft lip/palate is based on surgeons’ subjective evaluation of lip disability. An objective evaluation would be highly beneficial for the assessment of surgical outcomes. In this study, the effects of lip revision on circumoral movements were objectively quantified. The hypothesis was that lip revision increases scarring and impairment. The study was a non-randomized clinical trial that included patients with cleft lip who had revision, patients with cleft lip who did not, and non-cleft control individuals. Three-dimensional facial movements were measured. Revision patients were measured before and after surgery. Other individuals were measured at similar intervals. Regression models were fit to summary measurements, and changes were modeled. Patients with repaired cleft lip/palate had fewer mean movements than control individuals. Lip revision did not worsen mean movements; however, individual patients’ movements varied from ‘improvement’ to ‘no change’ to ‘worse’ relative to those of control individuals.

description: The aim of this study was to investigate the association of female caregivers’ oral health literacy with their knowledge, behaviors, and the reported oral health status of their young children. Data on caregivers’ literacy, knowledge, behaviors, and children’s oral health status were used from structured interviews with 1158 caregiver/child dyads from a low-income population. Literacy was measured with REALD-30. Caregivers’ and children’s median ages were 25 yrs (range = 17-65) and 15 mos (range = 1-59), respectively. The mean literacy score was 15.8 (SD = 5.3; range = 1-30). Adjusted for age, education, and number of children, low literacy scores (< 13 REALD-30) were associated with decreased knowledge (OR = 1.86; 95% CI = 1.41, 2.45) and poorer reported oral health status (OR = 1.44; 95% CI = 1.02, 2.05). Lower caregiver literacy was associated with deleterious oral health behaviors, including nighttime bottle use and no daily brushing/cleaning. Caregiver oral health literacy has a multidimensional impact on reported oral health outcomes in infants and young children.

title: Encountering St Margaret of Antioch in parochial and personal contexts in late Medieval England: devotional artefacts, memorialization and the construction of familial and communal identity
Creators: name: Cook, Frances M.
Publisher: name: University of Reading
Year: 2021

description: This thesis comprises a series of six case studies that form an exploration of lay devotion to St Margaret of Antioch over the period c.1250-c.1530. In a departure from previous approaches, the thesis examines reasons for Margaret’s enduring popularity through a discussion foregrounding the great range of surviving artefacts associated with her cult. The medieval perception of Margaret as protector of women in childbirth has been widely discussed and the saint’s formidable dragon-slaying powers likewise. Whilst these aspects of Margaret’s cult are relevant and examined again in this study, it is argued that the evidence of wall paintings, stained glass and manuscripts presented here establishes a clear connection between Margaret and the sacrament of baptism. Distinctively, this study further argues that such an association is reinforced by representations of St Nicholas alongside those of Margaret. Moreover, textual versions of Margaret’s Life also support this sacramental association. Parts One and Two of this thesis examine visual narrative cycles of Margaret’s passion in the communal context of parish churches to consider issues of their intended messages and patronage, as well as how devotees might have interacted with them. Part Three focuses on two books of hours that demonstrate a more intimate context for the veneration of Margaret by known individuals. The manuscripts offer opportunities to discuss what Margaret could have represented for these individuals and how they might have expressed their devotion. Finally, it is argued that far from being simply a Holy Helper, through her sacramental association Margaret occupied a fundamental position at the heart of orthodox Christian belief and practice. Although sought out in moments of personal significance, symbolically, and perhaps most significantly, Margaret also represented a bulwark against the influence of other faiths and heterodoxy.

description: Spin-orbit coupling is an important ingredient to regulate the many-body physics, especially for many spin liquid candidate materials such as rare-earth magnets and Kitaev materials. The rare-earth chalcogenides NaYbCh$_2$ (Ch = O, S, Se) is a congenital frustrating system to exhibit the intrinsic landmark of spin liquid by eliminating both the site disorders between Na$^{+}$ and Yb$^{3+}$ ions with the big ionic size difference and the Dzyaloshinskii-Moriya interaction with the perfect triangular lattice of the Yb$^{3+}$ ions. The temperature versus magnetic-field phase diagram is established by the magnetization, specific heat, and neutron-scattering measurements. Notably, the neutron diffraction spectra and the magnetization curve might provide microscopic evidence for a series of spin configuration for in-plane fields, which include the disordered spin liquid state, 120$^{o}$ antiferromagnet, and one-half magnetization state. Furthermore, the ground state is suggested to be a gapless spin liquid from inelastic neutron scattering, and the magnetic field adjusts the spin orbit coupling. Therefore, the strong spin-orbit coupling in the frustrated quantum magnet substantially enriches low-energy spin physics. This rare-earth family could offer a good platform for exploring the quantum spin liquid ground state and quantum magnetic transitions.

description: In the left-right symmetric model neutral gauge fields are characterized by three mixing angles $θ_{12}, θ_{23}, θ_{13}$ between three gauge fields $B_μ, W^3_{Lμ}, W^3_{Rμ}$, which produce mass eigenstates $A_{μ}, Z_{μ}, Z'_{μ}$, when $G = SU(2)_L\times SU(2)_R\times U(1)_{B-L} \times D$ is spontaneously broken down until $U(1)_{em}$. We find a new mixing angle $θ'$, which corresponds to the Weinberg angle $θ_{W}$ in the standard model with the $SU(2)_{L}\times U(1)_{Y}$ gauge symmetry, from these mixing angles. It is then shown that any mixing angle $θ_{ij}$ can be expressed by $\varepsilon $ and $θ'$, where $\varepsilon = g_L/g_R$ is a ratio of running left-right gauge coupling strengths. We observe that light gauge bosons are described by $θ'$ only, whereas heavy gauge bosons are described by two parameters $\varepsilon$ and $θ'$.

description: The molecular mechanisms that underlie dental fluorosis are poorly understood. The retention of enamel proteins hallmarking fluorotic enamel may result from impaired hydrolysis and/or removal of enamel proteins. Previous studies have suggested that partial inhibition of Mmp20 expression is involved in the etiology of dental fluorosis. Here we ask if mice expressing only one functional Mmp20 allele are more susceptible to fluorosis. We demonstrate that Mmp20+/− mice express approximately half the amount of MMP20 as do wild-type mice. The Mmp20 heterozygous mice have normal-appearing enamel, with Vickers microhardness values similar to those of wild-type control enamel. Therefore, reduced MMP20 expression is not solely responsible for dental fluorosis. With 50-ppm-fluoride (F−) treatment ad libitum, the Mmp20+/− mice had F− tissue levels similar to those of Mmp20+/+ mice. No significant difference in enamel hardness was observed between the F−-treated heterozygous and wild-type mice. Interestingly, we did find a small but significant difference in quantitative fluorescence between these two groups, which may be attributable to slightly higher protein content in the Mmp20+/− mouse enamel. We conclude that MMP20 plays a nominal role in dental enamel fluorosis.

description: The paper revisits the classical problem of evaluating $f(A)$ for a real function $f$ and a matrix $A$ with real spectrum. The evaluation is based on expanding $f$ in Chebyshev polynomials, and the focus of the paper is to study the convergence rates of these expansions. In particular, we derive bounds on the convergence rates which reveal the relation between the smoothness of $f$ and the diagonalizability of the matrix A. We present several numerical examples to illustrate our analysis.

description: We propose a two-spin quantum-mechanical model with applied magnetic fields acting on the Poincaré-Bloch sphere, to reveal a new class of topological energy bands with Chern number one half for each spin-1/2. The mechanism behind this fractional topology is a two-spin product state at the north pole and a maximally entangled state close to the south pole. The fractional Chern number of each spin can be measured through the magnetizations at the poles. We study a precise protocol where the spin dynamics in time reflects the Landau-Zener physics associated with energy band crossing effects. We show a correspondence between the two-spin system and topological bilayer models on a honeycomb lattice. These models describe semimetals with a nodal ring surrounding the region of entanglement.

description: We develop a generating functional description of the dynamics of non-Markovian individual-based systems, in which delay reactions can be terminated before completion. This generalises previous work in which a path-integral approach was applied to dynamics in which delay reactions complete with certainty. We construct a more widely applicable theory, and from it we derive Gaussian approximations of the dynamics, valid in the limit of large, but finite population sizes. As an application of our theory we study predator-prey models with delay dynamics due to gestation or lag periods to reach the reproductive age. In particular we focus on the effects of delay on noise-induced cycles.

Fluoride’s Effects on the Formation of Teeth and Bones, and the Influence of Genetics
Creators: name: Everett, E.T.

description: Fluorides are present in the environment. Excessive systemic exposure to fluorides can lead to disturbances of bone homeostasis (skeletal fluorosis) and enamel development (dental/enamel fluorosis). The severity of dental fluorosis is also dependent upon fluoride dose and the timing and duration of fluoride exposure. Fluoride’s actions on bone cells predominate as anabolic effects both in vitro and in vivo. More recently, fluoride has been shown to induce osteoclastogenesis in mice. Fluorides appear to mediate their actions through the MAPK signaling pathway and can lead to changes in gene expression, cell stress, and cell death. Different strains of inbred mice demonstrate differential physiological responses to ingested fluoride. Genetic studies in mice are capable of identifying and characterizing fluoride-responsive genetic variations. Ultimately, this can lead to the identification of at-risk human populations who are susceptible to the unwanted or potentially adverse effects of fluoride action and to the elucidation of fundamental mechanisms by which fluoride affects biomineralization.

description: The Berry phase picture provides important insights into the electronic properties of condensed matter systems. The intrinsic anomalous Hall (AH) effect can be understood as a consequence of non-zero Berry curvature in momentum space. The realization of the quantum anomalous Hall effect provided conclusive evidence for the intrinsic mechanism of the AH effect in magnetic topological insulators (TIs). Here we fabricated magnetic TI/TI heterostructures and found both the magnitude and sign of the AH effect in the magnetic TI layer can be altered by tuning the TI thickness and/or the electric gate voltage. The sign change of the AH effect with increasing TI thickness is attributed to the charge transfer across the TI and magnetic TI layers, consistent with first-principles calculations. By fabricating the magnetic TI/TI/magnetic TI sandwich heterostructures with different dopants, we created an artificial topological Hall (TH) effect-like feature in Hall traces. This artificial TH effect is induced by the superposition of two AH effects with opposite signs instead of the formation of chiral spin textures in the samples. Our study provides a new route to engineer the Berry curvature in magnetic topological materials that may lead to potential technological applications.

description: Gene expression profiles of human ameloblastoma microdissected cells were characterized with the purpose of identifying genes and their protein products that could be targeted as diagnostic and prognostic markers as well as for potential therapeutic interventions. Five formalin-fixed, decalcified, paraffin-embedded samples of ameloblastoma were subjected to laser capture microdissection, linear mRNA amplification, and hybridization to oligonucleotide human 41,000 RNA arrays and compared with universal human reference RNA, to determine the gene expression signature. Assessment of the data by Significance Analysis of Microarrays (SAM) and cluster analysis showed that 38 genes were highly expressed (two-fold increase) in all samples, while 41 genes were underexpressed (two-fold reduction). Elements of the sonic hedgehog pathway and Wingless type MMTV integration site family were validated by immunohistochemistry. We have identified the expression of multiple genes and protein products that could serve as potential diagnostic, prognostic, and therapeutic targets.

description: The first meeting between La Rivista di Engramma and Giovanni Testori focuses on two typical themes for the journal: writing and figure. Testori. Scrittura e figura is Engramma's portrait dedicated to Testori 100 years after his birth and 30 years after his death. It takes as its reference Willy Varlin's portrait of Testori chosen as the issue's cover. The issue includes a first part centred on Testori's writing: Chiara Pianca in “Quasi fudesse ecce homo de paese” writes an in-depth and detailed essay on the complex drafting of Ambleto. Alongside this, Luca D'Onghia in his article Lettera luterana su Edipus gives a possible identification of the “scarrozzante” king of Thebes. The remainder of the issue is dedicated to art and the figure. Primarily Testori. Figure dell'informe, by Arturo Mazzarella, which links Testori's thought to 20th-century aesthetic philosophy and the notion of formlessness. This is followed by Apostasia della carne. Fatica e liberazione della materia in Giovanni Testori e Francis Bacon, by Filippo Perfetti: a contribution that reveals some traits of Testori's and Bacon's conception of painting, and how pictorial matter is linked to human life and biology. Davide Dall'Ombra, with Nell'anno del libro su Giovanni Testori e Roberto Longhi, talks about the Testori-Longhi relationship through their exchange of letters, an anticipation that introduces his forthcoming publication Con Roberto Longhi. Lettere e scritti. 1951-1990. The section is closed by the republication of a writing by Giovanni Testori (for which we thank the Associazione Giovanni Testori, and in particular Giuseppe Frangi): Grünewald, il trionfo e la bestemmia. In its concluding part, the issue focuses on the theatrical version of “In exitu”. Here we give for the first time an edition of the reduction used by Testori on his novel for the script. Accompanying the text and the reader is Piermario Vescovo, author of a brief Nota, which briefly attempts to indicate the relevance and further possibility of interrogation of the theatrical script. The conversation “In piena luce, in piena ombra” is a dialogue between Franco Branciaroli, the actor for whom the text of "In exitu" was cut, and Piermario Vescovo. Maestro no, incipit and title of the interview conducted by Antonio Ria with Testori, closes (provisionally) this issue through the voice of its protagonist.
