Published: November 2022

Objectives: Cervical duplex ultrasonography (CDU) is a simple, non-invasive, portable technique, that provides valuable high-quality visual information about the integrity of the carotid and vertebral vessels, plaque morphology and flow hemodynamics. CDU is useful in the assessment and follow up of patients with cerebrovascular disease as well as other conditions like inflammatory vasculitis, carotid artery dissection and carotid body tumours. CDU is inexpensive and invaluable in smaller centres. Methods: CDU was performed in all patients in both longitudinal and transverse planes in the out-patient clinic. Brightness mode (B-mode) and Doppler waveforms were obtained. Relevant findings were presented. Results: CDU provides real time visualisation of plaque characteristics and follow up, hemodynamic characteristics in Takayasu arteritis, visualisation of dissection. Conclusion: With availability of MR/CT angiography, CDU can be an adjuvant in follow up, triage and early bed-side diagnosis of the vascular diseases. We present our experience with CDU in the out-patient clinics in this pictorial essay.
Transesophageal Echocardiography Guided Partial Right Atrial Inflow Occlusion - A Case Study
Authors: Barboza Lucas , Tanzola Rob
Published: November 2022

Deployment of stent-grafts and other endovascular devices is a common technique for various vascular repair procedures. Induced, transient, periods of hypotension are essential to the precise deployment of a device as this minimizes displacement that can result from high pressure aortic flow. Partial inflow occlusion of the right atrium is a reliable, precise, and safe method of achieving this. We present a case where intraoperative transesophageal echocardiography (TEE) was used to guide and confirm balloon placement for right atrium inflow occlusion during a thoracic endovascular aneurysm repair (TEVAR) procedure for repair of an aortic dissection in a 67 year old male. This highlights a novel use of TEE in the context of endovascular surgery, and showcases an alternative method of reliably achieving transient hypotension.

Chloride based solid electrolytes are considered interesting candidates for catholytes in all-solid-state batteries due to their high electrochemical stability, which allows the use of high-voltage cathodes without protective coatings. Aliovalent Zr(IV) substitution is a widely applicable strategy to increase the ionic conductivity of Li3M(III)Cl6 solid electrolytes. In this study, we investigate how Zr(IV) substitution affects the structure and ion conduction in Li3-xIn1-xZrxCl6 (0 ≤ x ≤ 0.5). Combined refinement of x-ray and neutron diffraction is used to make a structural model based on both scattering contrasts, and AC-impedance measurements and solid-state NMR relaxometry measurements at multiple Larmor frequencies are used to study the Li-ion dynamics. Hereby the diffusion mechanism and its correlation with the structure are explored and compared to previous studies, advancing the understanding of these complex and difficult to characterize materials. It is found that the diffusion in Li3InCl6 is most ikely anisotropic considering the crystal structure and two distinct jump processes found by solid-state NMR. Zr-substitution improves ionic conductivity by tuning the charge carrier concentration, accompanied by small changes in the crystal structure which affect ion-transport even on short timescales, likely reducing the anisotropy.

The caspases are a family of cysteine dependent proteases with important cellular functions in inflammation and apoptosis, while also implicated in human disease. Classical chemical tools to study caspase function lack selectivity for specific caspase family members due to highly conserved active sites and catalytic machinery. To overcome this limitation, we tar-geted a non-catalytic cysteine residue (C264) unique to Caspase-6, an enigmatic and understudied caspase isoform. Starting from disulfide ligands identified in a cysteine trapping screen, we used structure-informed covalent ligand design to produce potent, irreversible inhibitors (e.g., 3a) and chemoproteomic probes (e.g., 13-t) of Caspase-6 that exhibit unprecedented se-lectivity over other caspase family members and high proteomic selectivity. This approach and the new tools described will enable rigorous interrogation of the role of Caspase-6 in developmental biology and in inflammatory and neurodegenerative diseases

Daptomycin is a cyclic lipopeptide antibiotic that targets the lipid membrane of Gram-positive bacteria. Membrane fluidity and charge can affect daptomycin activity, but its mechanisms are poorly understood because it is challenging to study daptomycin interactions within lipid bilayers. Here, we combined native mass spectrometry (MS) and fast photochemical oxidation of peptides (FPOP) to study daptomycin-membrane interactions with different lipid bilayer nanodiscs. Native MS suggests that daptomycin incorporates randomly and does not prefer any specific oligomeric states when integrated into bilayers. FPOP reveals significant protection in most bilayer environments. Combining the native MS and FPOP results, we observed that stronger membrane interactions are formed with more rigid membranes, and pore formation may occur in more fluid membranes to expose daptomycin to FPOP oxidation. Electrophysiology measurements further sup-ported the observation of polydisperse pore complexes from the mass spectrometry data. Together, these results demonstrate the complementarity of native MS, FPOP, and membrane conductance experiments to shed light on how antibiotic peptides interact with and within lipid membranes.

Two front-end engineering designs (FEED) for commercial-scale carbon capture from natural gas combined-cycle (NGCC) power plants have been published in full, including detailed capital cost estimates . The two studies are the Piperazine with the Advanced Stripper (PZAS) FEED at Mustang Station in Denver City, TX, USA (“Mustang FEED”) and the FEED at Panda Sherman Power Station in Sherman, TX, USA (“Panda FEED”). This work compares both designs with the aim of gaining insight about the cost of carbon capture processes. Direct field costs for each process are adjusted to account for differences in the estimating methodology in each FEED. This adjustment results in estimated direct field costs of $574MM for Mustang and $411MM for Panda. The breakdowns of capital costs for each process area are compared, to highlight differences in costs due to the respective processes or particular requirements of each host power plant. A key finding is that site-specific factors not typically represented in less rigorous cost estimates are observed to have a significant impact on cost. To compare both estimates on a similar design basis, the Mustang unit was scaled to the Panda FEED design capacity, resulting in direct field costs of $489MM for Mustang and $411MM for Panda. Additionally, the cost estimates of the CO2 absorbers are analyzed in greater detail to directly compare three equivalent designs that include rectangular and cylindrical absorber columns. Adjusting the absorber estimates to the same scope and scaling to the same size results in estimated costs of $19.7MM, $18.2MM, and $14.9MM, with the rectangular absorber approximately 10% to 30% more expensive than the cylindrical designs.
DIÁLOGOS SUR-SUR. REFLEXIONES SOBRE EL SUR, LAS DESIGUALDADES EPISTÉMICAS Y LA DEMOCRATIZACIÓN GLOBAL DE LOS SABERES

Una de las claves para comprender las desigualdades globales y buscar medios de superarla, está en aceptar y desarrollar un presupuesto teórico: las eufemísticamente llamadas “asimetrías” globales no son sólo económicas o geopolíticas. Son igualmente simbólicas. En eso se ubican los debates sobre la dependencia epistémica (Beigel, 2013) y la colonialidad del saber (2000), las reflexiones sobre “violencias epistémicas” y “epistemicidios” (Spivak, 1988, Santos, Meneses, 2009), sobre el sujeto colonial y poscolonial (Césaire, 2004, Fanon, 1966, Hall, 2015) y, en particular, sobre el papel del “intelectual periférico” y de la producción de conocimiento en los “Sures” (Devés, 2017). De hecho, se percibe que los saberes y conocimientos periféricos tienen menos legitimidad que los saberes centrales y frecuentemente no son considerados “ciencia” o “teoría”. Sus propuestas no circulan o circulan poco y tienden a desaparecer con el tiempo. Este libro es resultado de seguidos diálogos entre intelectualidades de los varios Sur. Hemos nombrado a estas instancias Encuentros Intelectuales Sur-Sur. Las contribuciones a este volumen derivan específicamente de la reunión realizada en mayo de 2022. Entre algunos avances y muchos bloqueos, seguimos en la senda de construir puentes entre los distintos “Sures”.

Twin Pillars of Resistance: Vodou and Haitian Kreyòl in Michel-Rolph Trouillot’s Ti difé boulé sou istoua Ayiti [Stirring the Pot of Haitian History]
Authors: Past Mariana
Published: November 2022

Michel-Rolph Trouillot’s first book, Ti difé boulé sou istoua Ayiti [Stirring the Pot of Haitian History] (1977), exposes the foundational role of Haitian Vodou and the Kreyòl language in Haiti’s Revolution (1791-1804). The unprecedented victory achieved by the enslaved people in the former French colony of Saint Domingue was a useful paradigm for subsequent Latin American independence movements, starting with Simón Bolívar’s liberation of Venezuela (1811-19). This essay analyzes selected passages from Ti difé boulé that explicitly incorporate Vodou songs, prayers, and terminology to show how Trouillot provocatively deploys oral sources of historical narrative and memory. The young activist, writing in Haitian Kreyòl from New York City during the darkest days of the Duvalier régime, powerfully contests official versions of Haitian history by emphasizing the Haitian people’s agency. Vodou and Kreyòl, born out of struggle within a repressive colonial framework, are the great coherencies underlying Haitian resistance. Ti difé boulé examines neocolonial patterns of oppression emerging during the nineteenth century and critiques revolutionary icon Toussaint Louverture, revealing how Haiti’s predatory State harnessed Vodou to continue systematically subjugating the Haitian people. Trouillot’s innovative yet understudied masterpiece offers contemporary readers “new narratives” of Haiti. As twin pillars of Haitian resistance and cultural identity, Vodou and Kreyòl remain a vital and vibrant part of the American heritage. They merit more nuanced understandings within a cultural and political context where they have increasingly come under siege, inside and outside of Haiti.
