Abstract:
When Venantius Fortunatus agreed to the request of Radegund and Agnes to versify the Vita Sancti Martini (VSM, pr. 29–30), he was well aware that he was not the first to write such a poem. About a century earlier Paulinus of Périgueux had versified Sulpicius Severus's Life of Martin (Vita) and books 2 and 3 of the Dialogues (Dial.), which contained supplementary stories about Martin's life. Fortunatus cites Paulinus's poem in the introductory section to the VSM (1.20–21) and, as frequent parallels in language demonstrate, clearly knew his predecessor's work well. But, as successive scholars have noted, the two poems, though sharing the same subject matter, create a very different impression. The VSM is unusual in Fortunatus's poetic corpus in its use of the hexameter and its narrative content. In this paper I will analyze the structure and style of Fortunatus's single venture into hagiographical epic in order to demonstrate the special qualities he brings to his narrative of the life of Saint Martin. I move from considering narrative structure, in the poem as a whole and in individual episodes, to a close analysis of style, concluding with a discussion of the function and distinctive features of the scenes in heaven with which books 2, 3, and the Martin portion of book 4 conclude. In so doing I will argue that the particular qualities of Fortunatus's poem, far from being extrinsic rhetorical flourishes, contribute to the poem's efficacy as an epic of meditation on Martin and his powers.

AbstractThis article explores aspects of the work of the composer Naomi Pinnock, focusing on six works written between 2012 and 2019: String Quartet No. 2 (2012), The Writings of Jakob Br. (2013), Lines and spaces (2015), Music for Europe (2016), The field is woven (2018) and I am, I am (2019). Each work is analysed and the analyses contextualised within a discussion of the works by other artists that form a creative hinterland to Pinnock's music: respectively art from the Sammlung Prinzhorn, paintings by Paul Klee and Agnes Martin, and the poetry of Rachael Boast.

Abstract:
Gabriel es una película en color de 78 minutos de duración y el único vídeo completo firmado por la celebrada pintora canadiense-estadounidense Agnes Martin (1912-2004). El filme, lleno de líricas imágenes de la naturaleza, sigue vagamente a un niño de 10 años mientras deambula por diferentes paisajes de Nuevo México. De bajo presupuesto, la cinta fue rodada en un período de cinco meses, sin guion ni storyboard, y fue realizada con una cámara Arriflex en película de 35 mm. El largometraje es silente, excepto por la introducción de varios extractos de las Variaciones Goldberg de Bach. Aunque considerada una anomalía en la producción de la pintora y generalmente eludida en retrospectivas y compendios de su trabajo, este texto examina la película experimental de 1976 en relación con su obra pictórica, su ideario poético y los temas de inocencia y exultación que Martin persiguió de manera agotadora como artista.

Abstract:
AbstractA considerable portion of Joan La Barbara's compositional work has been concentrated in her ‘sound paintings’ – works that translate into sound the visual and energetic sensation La Barbara experiences when encountering art. Many of these works are ‘ekphrastic’ – that is, they render aurally a pre-existing work. In this article, I analyse three such sound paintings: Klee Alee (based on Paul Klee's Hauptweg und Nebenwege), Rothko (based on Mark Rothko's Chapel paintings), and In solitude this fear is lived (inspired by the early work of Agnes Martin). I argue that these works extend the mimetic impulse of her vocal practice and use translational semiosis to produce their ekphrastic effects.

Abstract:
Abstract We set out to examine the behavior in preclinical models of a dual-receptor cell therapy approach (Tmod࣪ system) designed to exploit instances of somatic LOH in cancer that can be readily identified through molecular diagnostics. We utilized quantitative pharmacologic assays in vitro and dual-flank efficacy/selectivity models in vivo to test the activity of a variety of constructs comprised of: (i) CAR “activators” that target tumor-associated antigens (TAAs) such as CEA, MSLN and others; and, (ii) LIR-1-based “blockers” that target HLA class I proteins. We generated substantial datasets around multiple targets, including well known tumor-associated antigens (TAAs). In the presence of the HLA class I blocker antigen, Tmod cells were OFF within a wide range of activator antigen expression levels on the “normal” target cells. They were ON when tumor cells expressed the TAA without the HLA blocker antigen, and killed tumor cells selectively even in mixed tumor-normal cell populations. The Tmod system transformed imperfect TAAs into true tumor-selective targets, where the activity of the engineered T cells is controlled by the presence/absence of the HLA blocker antigen. The system was sufficiently modular to use with autologous and allogeneic products. Several of these Tmod constructs are advancing to the clinic where a robust genetic selection tool is being used to screen patients for treatment and match them with a suitable Tmod therapy. In summary, Tmod is a robust system with quantitative pharmacologic behavior in preclinical models consistent with efficacy and safety across a range of targets.

Abstract:
Abstract Introduction: Sotorasib, a first-in-class KRASG12C inhibitor, has been FDA-approved for adults with KRAS p.G12C-mutated locally advanced or metastatic NSCLC who received prior systemic therapies based on the Phase 1/2 global, single-arm CodeBreaK100 trial. We will report the longest follow-up for a KRASG12C inhibitor, including 2-year survival, safety, and genomic profiles associated with durable clinical benefit. Methods: Sotorasib was administered orally at 960 mg once daily to patients who progressed on prior therapies and had KRAS p.G12C-mutated locally advanced, metastatic NSCLC. Primary endpoint was objective response rate (ORR) assessed by central review. Key secondary endpoints included duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety. In an exploratory analysis, baseline tumor tissue and/or plasma samples were collected and analyzed for genomic alterations. Tumor samples were analyzed for PD-L1 levels to evaluate correlates with prolonged tumor response, defined as patients with PFS ≥ 12 months, in comparison with those with PFS ≤ 3 months. Results: In the first analysis of the combined Phase 1 and Phase 2 study (N=174), the median number of prior lines of therapy was 2.0 (range 1-4+). 90.2% received prior anti-PD1 or anti PD-L1 treatment; 82.8% received both prior platinum-based chemotherapy and anti-PD1/PD-L1. Updated ORR by central review was 40.7% (95% CI: 33.2, 48.4) and median DOR was 12.3 months (7.1, 14.6). Median PFS and OS was 6.3 months (95% CI: 5.3, 8.2) and 12.5 months (10.0, 17.8). One and two-year OS was 50.8% and 30.3%. Sotorasib was well-tolerated in the long-term with mild and manageable toxicities, and no new safety signals emerged. Prolonged tumor response was observed across PD-L1 expression, including in tumors with low PDL-1 expression and STK11 co-mutation that may derive less benefit from immunotherapy. Conclusions: In the longest follow-up of any KRASG12C inhibitor, sotorasib continued to demonstrate a favorable safety profile and durable efficacy, including a 2-year OS observed in 30% of patients. Current analyses continue to support long-term clinical benefit across subgroups in patients with KRAS p.G12C-mutated NSCLC, and additional biomarker data will be presented. Citation Format: Grace K.

Abstract:
AbstractAt several times during the Quaternary, a major eastward-flowing outlet glacier of the former Patagonian Ice Sheet occupied the Lago San Martin Valley in Argentina (49°S, 72°W). We present a glacial chronology for the valley based on geomorphological mapping and cosmogenic nuclide (10Be) exposure ages (n = 10) of boulders on moraines and lake shorelines. There are five prominent moraine belts in the Lago San Martin Valley, associated with extensive sandar (glaciofluvial outwash plains) and former lake shorelines. Cosmogenic nuclide exposure ages for boulders on these moraines indicate that they formed at 14.3 ± 1.7 ka, 22.4 ± 2.3 ka, 34.4 ± 3.4 ka to 37.6 ± 3.4 ka (and possibly 60 ± 3.5 ka), and 99 ± 11 ka (1σ). These dated glacier advances differ from published chronologies from the Lago San Martin Valley based on 14C age determinations from organic sediments and molluscs in meltwater channels directly in front of moraines or in kettleholes within end moraine ridges. The moraine boulder ages also point to possible pre-LGM glacial advances during the last glacial cycle and a key observation from our data is that the LGM glaciers were probably less extensive in the Lago San Martin Valley than previously thought.

Abstract:
Due to their properties, silver nanoparticles (AgNPs) are widely used in consumer products. The widespread use of these products leads to the release of such nanoparticles into the environment, during manufacturing, use, and disposal stages. Currently there is a high margin of uncertainty about the impacts of nano products on the environment and human health. Therefore, different approaches including life cycle assessment (LCA) are being used to evaluate the environmental and health impacts of these products. In this paper, a comparison between four different AgNP synthesis methods was conducted. In addition, four textile products that contain AgNPs were subjected to comparison using LCA analysis to assess their environmental and public health impacts using SimaPro modeling platform. Study results indicate that using alternative methods (green) to AgNPs synthesis will not necessarily reduce the environmental impacts of the synthesizing process. To the best of our knowledge, this is the first study that has compared and assessed the environmental burdens associated with different nanosilver-based textile products at different disposal scenarios. The synthesis of 1 kg of AgNPs using modified Tollens’ method resulted in 580 kg CO2 eq, while 531 kg CO2 eq resulted from the chemical approach. Furthermore, the manufacturing stage had the highest overall impacts as compared to other processes during the life cycle of the product, while the product utilization and disposal stages had the highest impacts on ecotoxicity. Sensitivity analysis revealed that under the two disposal scenarios of incineration and landfilling, the impacts were sensitive to the amount of AgNPs.

Abstract:
BackgroundThe heterogeneity and complexity of the chronic autoimmune diseases systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) necessitate comprehensive person-centred management, including non-pharmacological approaches. Recommendations for non-pharmacological management are currently lacking.ObjectivesTo perform a systematic literature review to inform the EULAR task force for recommendations/points to consider for the non-pharmacological management of adult patients with SLE and SSc. Among research questions formulated by the task force, we aimed at identifying (i) non-pharmacological interventions that have been evaluated and (ii) their target health domains or organ systems.MethodsWe searched the Medline, Embase, Web of Science Core Collection and CINAHL for articles published between January 2000 and June 2021. From the initial search (n=15,803), 2 researchers independently performed the article selection. Conflicts were discussed until consensus with 2 additional researchers. Subsequent data extraction from the selected articles was performed by 4 researchers, with an overarching guidance by 2 additional researchers. Risk of bias assessment was performed according to Joanna Briggs Institute Critical Appraisal Checklists.ResultsA total of 111 articles for SLE and 75 for SSc were selected for analysis.Non-pharmacological interventions identified for SLE included physical exercise (n=34), psychological support (n=21), dietary therapy and nutrition (n=15), patient education and self-management (n=14), photoprotection (n=5), medication adherence interventions (n=5), complementary and alternative medicine (CAM) e.g., Chinese medicine (n=5), multidisciplinary care (n=4), and phototherapy/laser modalities (n=4).Interventions identified for SSc included physical exercise e.g., hand, oral and general exercise (n=21), phototherapy/laser modalities or shockwave therapy (n=15), patient education and self-management (n=10), CAM (n=8), hand-bathing e.g., in paraffin (n=5), manual therapy e.g., osteopathic manipulative treatment (n=5), dietary therapy and nutrition (n=5), oral hygiene (n=2), hyperbaric oxygen or ozone therapy (n=2) and multidisciplinary care (n=2).Target health domains and organ systems identified within SLE included (in descending order) (i) disease activity, (ii) health-related quality of life (HRQoL), (iii) depression/anxiety, (iv) fatigue, (v) organ damage, (vi) inflammatory markers, (vii) psychological stress, (viii) pain, (ix) body composition/anthropometry, and (x) aerobic capacity.Intervention targets in SSc included (i) functional impairment e.g., hand mobility, (ii) skin sclerosis including microstomia, (iii) HRQoL, (iv) pain, (v) circulation e.g., Raynaud’s phenomena and telangiectasias, (vi) skin ulcers, (vii) oral hygiene, (viii) fatigue, (ix) digestion, and (x) depression/anxiety.ConclusionPhysical exercise was a frequently researched non-pharmacological intervention within both SLE and SSc. While psychological support and dietary therapy/nutrition were frequently investigated in SLE, phototherapy modalities were common in SSc. Patient education and self-management was advocated in both SLE and SSc literature. HRQoL was a frequent target domain in both diseases; while disease activity and psychosocial domains emerged as important targets in SLE, functional impairment and skin-related aspects constituted predominant targets in SSc. Efficacy of interventions varied considerably across studies. Current evidence is limited by the overall small study populations, and the lack of large RCTs.Table 1.Studies categorised by design.Study designSLESScMeta-analysis of RCTs51RCT (including long-term follow-up or post-hoc analysis)4128Non-randomised longitudinal controlled/cohort studies287Retrospective cohort study, cross-sectional or case-control study162Case series or open pilot studies2137AcknowledgementsThe authors would like to thank the members of the EULAR task force for recommendations/points to consider for the non-pharmacological management of systemic lupus erythematosus and systemic sclerosis (in alphabetical order by family name) i.e., Helene Alexanderson, Laurent Arnaud, Oliver Distler, Andrea Domján, Els van den Ende, Kim Fligelstone, Agnes Kocher, Maddalena Larosa, Martin Lau, Alexandros Mitropoulos, Mwidimi Ndosi, Gunilla von Perner, Janet Poole, Anthony Redmond, Valentin Ritschl, Yvonne Sjöberg, Tillmann Uhlig, Cecília Varjú, Joke Vriezekolk, Elisabet Welin, and Rene Westhovens, for their contribution to the formulation of the research questions together with IP, CG, TS and CB.Disclosure of InterestsNone declared

Abstract:
This study evaluated the risk of silver nanoparticle (AgNP) exposure from antibacterial sprays containing AgNPs. Using an exposure simulation chamber as the setting for the experiment, various instruments, including a scanning mobility particle sizer (SMPS), condensation particle counter (CPC), dust monitor, and mixed cellulose esters (MCE) filters, are connected to the chamber to measure the exposure levels of AgNPs when using the sprays. To assess potential risks to consumers, margin of exposure (MOE) approach was used to assess risk in which a calculated MOE was compared with a target MOE. When evaluating the risk of antibacterial sprays to inhalation exposure using the MOE, spraying a whole can and spraying an air conditioner both resulted in a high-risk concern level with a MOE ranging from 59 to 146 that was much lower than the no-risk concern level of 1000, while some spray showed a MOE 2049 with no-risk concern level. The dermal exposure levels with a single layer of clothing were estimated at 2–50 μg/kg/day with a MOE ranging from 20,000 to 500,000. Therefore, the current results showed the possibility of high-risk inhalation exposure to AgNPs released when using antibacterial sprays.

Abstract:
AbstractIn the 1997/98 austral summer field season, we conducted a ground-penetrating radar survey on the northern shear margin of Ice Stream C, West Antarctica. The radar data were used to identify features near the surface of the ice, including internal layers and buried crevasses. The survey was intended to determine the variation in the age of buried crevasses along the ice stream. A procedure was developed by which the accumulation rate and the age of buried crevasses can be estimated based on radar records, firn-core measurements and the assumption that the crevasses were once open to the surface. With this method we were able to determine the age of buried crevasses with a standard error of 15–20%. We discuss our new results in conjunction with those of Retzlaff and Bentley (1993) on the southern margin of the ice stream. Typical crevasse ages were found to range from 120 to 200 years, although crevasses in a few areas were significantly younger. The youngest crevasses are at the extreme upstream end of the survey, but the next youngest were found midway along the ice stream. Crevasses upstream and downstream are older, with ages 40–80 years greater than those in the middle. Crevasses on the northern shear margin of tributary C2 were 30–50 years older than those on the southern margin. These patterns of crevassing suggest that variability in shear margin response to changes in ice-stream flow played an essential role in determining the time at which crevassing became inactive.

Abstract:
The analysis of published and unpublished 368 K/Ar radiometric ages of basic, intermediate and alkaline volcanic rocks, related to the post-Paleozoic magmatism linked to the opening of the South Atlantic Ocean, yields some important evidence concerning the break up of the Gondwana supercontinent. At the Brazilian Equatorial margin, the Gondwana break up started in the Permo-Triassic, when the opening of the Equatorial South Atlantic Ocean began and spread out south-eastward up to the present day Amazon River mouth. During the middle Jurassic/lower Cretaceous (pre-Aptian), the continuity of this separation, towards the Potiguar Basin, was coeval with the northward opening of the south-east Brazilian margin, up to the Espírito Santo State latitude. The relationship between large volcanic events in the basins and the resistance to the rifting process development offered by the cratonic area was shown by the trend of the magmatic age. Along the equatorial margin, the fragmentation resistance caused by the São Luis / West African craton is manifested by a large basic magmatism described in the Tacutu, Acre, Solimões, Amazonas and Parnaíba basins. A similar mechanism along the south-east margin, is proposed for the magmatism described in the Paraná Basin which is associated with the fracturing resistance offered by the São Francisco/Congo cratonic area. The integration of geochronological, micropalentological, sedimentological and geochemical data from the basins of the east Brazilian continental margin supports a model to explain the final disruption between South America and Africa during Cenonian/Turonian time. This model implies that 90 Ma basic magmatic rocks, related to the oceanic crust formation, probably occur offshore from the present-day eastern Brazilian coast line.

Abstract:
The Palaeoproterozoic Southern Province comprises a thick, continental rift related volcanic-sedimentary sequence along the southern margin of the Archaean Superior Province. The Agnew Intrusion (50 km2), which is a member of the East Bull Lake suite of layered intrusions, occurs adjacent to the Superior Province - Southern Province boundary in central Ontario, Canada, and provides an opportunity to examine the early tectono-magmatic evolution of a Palaeoproterozoic rifting event. The Agnew Intrusion is a well-exposed, 2100 m thick, layered gabbronoritic to leucogabbronoritic pluton. It was the product of at least four recognizable, but chemically similar, high-Al2O3 and low-TiO2 magma pulses. Structural data, coupled with excellent stratigraphic correlations between the Agnew Intrusion and other East Bull Lake suite layered intrusions, suggest that these plutons are erosional remnants of one or more sill-like bodies that may originally have formed an extensive, subhorizontal mafic sheet. We argue on the basis of field evidence that the early evolution of the Southern Province was characterized by a large, mantle plume induced magmatic event that gave rise to a Palaeoproterozoic continental flood basalt province. However, the incompatible trace element characteristics of the Agnew Intrusion parental magma (i.e., large ion lithophile and light rare earth element enrichment and high field strength element depletion) are more typical of modern subduction-modified subcontinental lithospheric mantle. Given that this is a prevailing geochemical signature of mafic rocks in the Archaean-Palaeoproterozoic, we suggest that there was a fundamental difference in both the composition and structure between the ancient and more modern mantle. "Subduction-like" geochemical signatures may have been imparted to the entire developing mantle during early Earth differentiation.

Abstract:
AbstractThe Dead Sea fault (DSF) is one of the most active plate boundaries in the world. Understanding the Quaternary history and sediments of the DSF requires investigation into the Neogene development of this plate boundary. DSF lateral motion preceded significant extension and rift morphology by ~10 Ma. Sediments of the Sedom Formation, dated here between 5.0 ± 0.5 Ma and 6.2−2.1+inf Ma, yielded extremely low 10Be concentrations and 26Al is absent. These reflect the antiquity of the sediments, deposited in the Sedom Lagoon, which evolved in a subdued landscape and was connected to the Mediterranean Sea. The base of the overlying Amora Formation, deposited in the terminal Amora Lake which developed under increasing relief that promoted escarpment incision, was dated at 3.3−0.8+0.9 Ma. Burial ages of fluvial sediments within caves (3.4 ± 0.2 Ma and 3.6 ± 0.4 Ma) represent the timing of initial incision. Initial DSF topography coincides with the earliest Red Sea MORB's and the East Anatolian fault initiation. These suggest a change in the relative Arabian–African plate motion. This change introduced the rifting component to the DSF followed by a significant subsidence, margin uplift, and a reorganization of relief and drainage pattern in the region resulting in the topographic framework observed today.

Abstract:
Abstract Background: H3K27M-mutated DMGs are universally lethal central nervous system tumors that express high levels of the disialoganglioside GD2. IV administered GD2-CAR T cells (GD2-CART) regress DMG in preclinical models, and locoregionally delivered CARs demonstrate enhanced activity in xenograft models of brain tumors. Methods: NCT04196413 is a 3+3 Phase I dose escalation trial testing GD2-CART in patients with H3K27M DMG, with dose-limiting toxicities (DLT) considered independently for DIPG and spinal DMG (sDMG). Arm A tested escalating doses of IV GD2-CART (DL1: 1e6 GD2-CART/kg; DL2=3e6 GD2-CART/kg) following lymphodepletion (LD). After the DLT period, patients with clinical and/or radiographic benefit were eligible for subsequent ICV GD2-CART (10-30e6 GD2-CART) administered via Ommaya catheter without LD every 4-8 weeks for a maximum of 12 doses. We previously reported early results from 4 patients treated on DL1, which demonstrated clinical activity and manageable toxicity. Here we provide updated results for DL1 and DL2. Results: Thirteen subjects were enrolled and 11 treated [n=4 DL1 (3 DIPG/1 sDMG); n=9 DL2 (7 DIPG/2 sDMG)]. Two subjects were removed prior to treatment due to rapid progression. No DLTs were observed on DL1. Three subjects experienced DLT on DL2 (2 DIPG/1 sDMG) due to grade 4 cytokine release syndrome (CRS), successfully managed with tocilizumab, anakinra, and corticosteroids. CRS occurred earlier on DL2 vs. DL1 (Day 3 vs 7). On both dose levels, all subjects exhibited transient symptoms related to on-tumor inflammation, termed Tumor Inflammation-Associated Neurotoxicity (TIAN), which was successfully managed with anakinra and, in some cases, CSF drainage and dexamethasone. No DLT due to TIAN has occurred. Ten patients have had adequate follow-up to assess benefit. Nine experienced radiographic and/or clinical benefit after IV infusion, and they received subsequent ICV GD2-CART infusions (median= 4 ICV infusions/pt, range 1-6). ICV infusions were not associated with high-grade CRS, although some subjects developed transient fever, headache, meningismus, nausea, and/or vomiting, and several subjects developed TIAN. Four patients continue to receive ICV infusions on study and have experienced continued clinical and radiographic benefit at 11+, 9.5+, 8+ and 7+ months following enrollment. A 31-year-old with sDMG has experienced a near-complete (>95%) reduction in tumor volume and a 17-year-old with DIPG experienced a near-complete (>98%) reduction in volume of a pontine tumor. Conclusions: IV treatment of DIPG and sDMG with GD2-CART is safe at a dose of 1e6/kg, but associated with unacceptable rates of high-grade CRS at 3e6/kg. ICV GD2-CART without LD, administered following a previous course of IV GD2-CART with LD, has been well tolerated and has mediated impressive sustained clinical benefit in some patients with DIPG/sDMG. Given these findings, we are launching a new arm to assess safety and activity and to define the recommended phase 2 dose for ICV delivery of GD2-CART without LD. Patients are eligible for up to 12 ICV infusions of GD2-CART administered every 4-6 weeks. Clinical benefit will be formally assessed using patient-reported outcomes. GD2-CART has the potential to transform therapy for patients with H3K27M+ DIPG/sDMG. Citation Format: Robbie G.

Abstract:
The New Quebec Orogen is a Paleoproterozoic fold and thrust belt, active from 2.17 to 1.77 Ga, bordering the eastern margin of the Archean Superior Province. The orogen developed on a long-lived, passive continental margin and comprises two volcanic – sedimentary sequences. The ages presented in this study help to bracket the magmatic and deformational history of the orogen. A glomeroporphyritic gabbro from the Hellancourt Formation was dated at 1874 ± 3 Ma and a rhyodacite from the upper Murdoch Formation yielded an identical age of 1870 ± 4 Ma. These data allow the correlation of the two units and indicate that they are 10–14 Ma younger than the estimated age for the Sokoman Formation. These ages, together with already published work, indicate that magmatism related to the younger magmatic event occurred at 1884–1870 Ma. Albitized pelites from the Murdoch Formation contain euhedral detrital zircons 2707–2690 Ma old, indicating that the source rocks were Archean. An undeformed monzonitic intrusion occurring close to Nachicapau Lake is 1813 ± 4 Ma old and is the lower limit for the age of deformation in the central sector of the orogen.
