Authors: Punjabi Avi , Woodward C. E. 
Published: September 2021

Abstract
Classical novae contribute to the cycle of chemical enrichment of the interstellar medium through through explosive nucleosynthesis and the violent ejection of material dredged from the white dwarf progenitor and mixed with the accreted surface layers. Analysis of archival NASA Spitzer spectroscopic observations of V2615 Ophiuchus shows that [O iv] 25.89 μm is a strong coolant and that no evidence for deceleration of the ejecta was present ∼1000 days after outburst, based on observed Spitzer InfraRed Spectrograph emission line average FWHM velocities of ≃600 km s−1.
Exploring Ceres’s Unusual Regolith Porosity and Its Implications for Volatile Retention

Published: September 2021

Abstract
Asteroid Ceres, the only dwarf planet located in the inner solar system, shows unique surface mineralogy and geomorphology as observed by the Dawn mission. Of particular interest is understanding the role that upper regolith porosity plays in retaining volatiles and shaping Ceres’ surface. Unfortunately, Ceres’ near-surface porosity remains largely uncharacterized, compromising the ability to quantify volatile occurrence and identify the mechanisms for volatile retention at shallow depths, a topic of ongoing debate. Herein, we estimate Ceres’ shallow-subsurface porosity by reinterpreting existing S- and X-band Earth-based radar observations combined with dielectric laboratory measurements of analog materials that have been recently suggested by spectral observations from the Dawn VIR spectrometer and in the far-ultraviolet from the Hubble telescope. Contrary to previous assumptions, our results suggest that Ceres’ surface is more porous than the lunar regolith, with a bulk porosity ranging from ∼53% to 72% or even higher in the top meter of the regolith, as opposed to ∼39% to 50% for both bodies. The above suggests that Ceres’ regolith is on average 15% more porous than the Moon, hence explaining its higher potential for volatile retention. We propose that lofting and gradual redeposition of fine particles by avalanches, continuous micrometeorite bombardment, and localized volatile outgassing are possible mechanisms for generating a globally high-porosity regolith. In addition to Ceres’ proximity to the snowline of the early solar system, such a highly porous regolith may explain its efficiency at retaining volatiles at shallow depths into the present, as revealed by Dawn’s GRaND observations.

Published: September 2021

Phytoplankton is a sentinel group of organisms of climate change due to their capacity to respond to multiple stressors, so studies documenting the optimal optical conditions within the water column affecting their growth and production are imperative. As a contribution to this topic, this study report selected optical properties in deep-waters of the Gulf of Mexico by in situ measurements during summertime. A multidisciplinary research cruise was carried during August/September of 2018. A CTD instrument configured with underwater quantum and fluorescence sensors were used to acquire data of temperature, conductivity, depth, photosynthetically active radiation (PAR), and fluorescence of chlorophyll-a, which were used to determine selected optical coefficients, including the light extinction (k), the compensation light intensity (Ec), the compensation depth (Zc), the critical depth (Zcr), and the incident irradiance (E0). The Brunt-Väisälä frequency calculated from CTD data was used as a magnitude indicator of the water column stratification. The results showed a pycnocline located between 23 and 68 m depth, and favorable conditions for phytoplankton production with high values of E0 reaching 1523.4 μmol m-2 s-1, Ec values ranging from 3 to 8 μmol m-2 s-1, values of Zcr greater than Zc and maximum records of k values of 0.06. Based on multivariate statistical techniques, two zones were clearly defined. These results represent the first observational report on the optical properties in the deep region of the Gulf of Mexico. Studies on the ideal optical conditions for carrying out phytoplankton photosynthesis and their possible seasonal and interannual variability are essential to understand the processes that support the phytoplankton production, especially in regions that are characterized by their high biodiversity.
An Updated Model for the Epigenetic Regulation of Effector and Memory CD8+ T Cell Differentiation
Authors: Xu Tianhao , Pereira Renata M , Martinez Gustavo J 
Published: September 2021

Abstract
Naive CD8+ T cells, upon encountering their cognate Ag in vivo, clonally expand and differentiate into distinct cell fates, regulated by transcription factors and epigenetic modulators. Several models have been proposed to explain the differentiation of CTLs, although none fully recapitulate the experimental evidence. In this review article, we will summarize the latest research on the epigenetic regulation of CTL differentiation as well as provide a combined model that contemplates them.
A SiC Double-Sided Stacked Wire-Bondless Power Module for High-Frequency Power Electronic Applications
Authors: Huang Si , Chen Zhong 
Published: September 2021

Abstract
This article reports a double-sided stacked wire-bondless power module package for silicon carbide (SiC) power devices to achieve low parasitic inductance and improved thermal performance for high-frequency applications. The design, simulation, fabrication, and characterization of the power module are presented. A half-bridge module based on the SiC power MOSFETs is demonstrated with minimized parasitic inductance. Double-sided cooling paths are used to maximize heat dissipation. Besides conventional packaging materials used in the power module fabrication, a low-temperature cofired ceramic (LTCC) and nickel-plated copper balls are used in this module package. The LTCC acts as an interposer providing both electrical and thermal routings. The nickel-plated copper balls replace bond wires as the electrical interconnections for the SiC power devices. The electrical and thermo-mechanical simulations of the power module are performed, and its switching performance is evaluated experimentally.
GLUCOSE METABOLISM AND INSULIN RESPONSE TO ORAL GLUCOSE TOLERANCE TEST (OGTT) IN PREPUBERTAL PATIENTS WITH TRANSFUSION DEPENDENT Β-THALASSEMIA (TDT): A LONG-TERM RETROSPECTIVE ANALYSIS
Authors: De Sanctis Vincenzo , Soliman Ashraf , Tzoulis Ploutarchos , Daar Shahina , Di Maio Salvatore , Fiscina Bernadette , Kattamis Christos 
Published: September 2021

Background: Glucose dysregulation (GD), including prediabetes and diabetes mellitus (DM), is a common complication of transfusion dependent β-thalassemia (TDT) patients. The prevalence increases with age and magnitude of iron overload, affecting a significant proportion of patients. The development of GD is frequently asymptomatic and therefore an early diagnosis, according to the international guidelines, requires an annual oral glucose tolerance test (OGTT) in all TDT patients aged ten years or older.

Purpose: This retrospective study aims to evaluate the prevalence of GD in a homogenous population of prepubertal TDT patients and to enhance understanding of the pathogenesis and progression of glucose homeostasis in this group of patients.

Methods: A selected group of 28 TDT patients was followed for at least 10.3 years (range: 10.3 - 28.10 years) from prepubertal age (mean 11.0 ± standard deviation 1.1 years) to adulthood (28.7 ± 3.7 years). Glucose tolerance and insulin response to OGTT were assessed, and indices of β-cell function, insulin sensitivity and insulin secretion were calculated.

Results: At baseline, 18 TDT patients had normal glucose tolerance (NGT) and 10 isolated impaired fasting glycaemia (IFG), according to the American Diabetes Association (ADA) criteria. Compared to 18 prepubertal healthy controls (mean ± SD age: 10.9 ± 1.1 years), the fasting plasma glucose (FPG), basal insulin level and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index were significantly higher in the group of TDT patients (p= 0.001, 0.01 and 0.012, respectively). At the last observation, 7/18 patients (38.8%) with NGT and 9/10 (90%) with IFG at baseline deteriorated; 3 female patients developed type 2 DM (1 from the NGT group and 2 from the IFG group). Compared to adult controls, TDT patients with NGT had a reduced oral disposition index (DI) (p= 0.006), but no significant difference in HOMA-IR and Matsuda index. Conversely, all insulin indices (HOMA-IR, MI and DI) but one [insulinogenic index (IGI)] were statistically different in TDT patients with GD compared to controls.

Conclusion: This study shows a spectrum of disturbances in glucose homeostasis among TDT patients and that prepubertal patients with IFG are at higher risk for developing a deterioration of glucose metabolism.

Perforación videocolonoscópica. ¿Es factible suturar?
Authors: Schlain Sergio , Pérez Domínguez Rocío , Colman Melina Sofía 
Published: September 2021

INTRODUCCION: La perforación videocolonoscópica del colon es una complicación poco frecuente, aunque su riesgo se ha visto incrementado debido al enfoque en la prevención, diagnóstico y tratamiento de lesiones colorrectales. Pueden ocurrir durante la endoscopía diagnóstica o terapéutica con una frecuencia del 0.019-0.8% y 0.1-0.3% respectivamente y pueden estar relacionadas a varios mecanismos. El manejo puede ser conservador, endoscópico o quirúrgico y existe debate sobre el enfoque más adecuado. Presentamos un caso de nuestra experiencia en el que mostramos una colorrafia laparoscópica.

DESCRIPCION: Se presenta el caso de una mujer de 65 años que concurre para realizarse una videocolonoscopía de Screnning para cáncer de colon, con buena preparación intestinal. La perforación ocurre a nivel del ángulo rectosigmoideo y fue visualizada e inmediatamente diagnosticada por el endoscopista. Suspendido el estudio la paciente presentó leve dolor abdominal por lo que fue llevada a la sala de operaciones dentro de las 4 horas posteriores a la videocolonoscopía y realizandose una exploración laparoscópica.
Se utilizaron dos trocares de 5 mm y uno de 10mm. La perforación se identificó fácilmente, presentaba una extensión de 30x30 mm a nivel la unión recto-sigmoidea con escaso líquido libre. La perforación fue reparada en dos planos con poliglactina 910 continua 3-0. La cavidad peritoneal se lavó en todos los cuadrantes y se utilizó un drenaje abocado al fondo de saco de Douglas que se exteriorizó por uno de los orificios portales. Prueba neumática negativa. El tiempo operatorio completo fue de 60 minutos. La paciente evolucionó favorablemente, otorgándose el alta médica al 4° día postoperatorio con dieta general y buena función intestinal.

CONCLUSIONES: El cierre primario laparoscópico es un enfoque mínimamente invasivo seguro para el manejo de perforaciones colonoscópicas en ausencia de inflamación extensa o contaminación fecal. En manos experimentadas, permite evitar una laparotomía y otorga los beneficios de la cirugía miniinvasiva. La colorrafia laparoscópica debe considerarse en el tratamiento selectivo de las perforaciones colonoscópicas.

Authors: Cecchin Hareli Fernanda Garcia , Teixeira Irenides 
Published: September 2021

A poluição visual é um fenômeno que deve ser discutido, visto que afeta diretamente a qualidade de vida do cidadão, a paisagem e a memória urbana. O objetivo da pesquisa foi mapear a poluição visual, no espaço urbano, em Palmas-TO e comparar com a poluição visual existente em 2010. O estudo foi realizado por meio de registro fotográfico das peças publicitárias presentes nas 10 quadras do centro simbólico, em localidades de maior concentração de mídia externa. Os resultados apontam que outdoors de madeira e de metal, pequenas placas e faixas foram retiradas. Em algumas localidades onde o poder público conseguiu retirar os outdoors, a iniciativa privada incorporou a publicidade a sua estrutura predial. Os outdoors de metal sem anúncio continuam sendo uma problemática ainda não resolvida na cidade. Não foram encontrados painéis digitais nas localidades monitoradas. Ao longo dos 11 anos de comparação observou-se maior fiscalização por parte dos órgãos públicos. Aos gestores públicos e a sociedade civil sugere-se o contínuo monitoramento da poluição visual. Aos pesquisadores sugere-se estudos que considerem a influência da poluição visual nas ocorrências de acidentes de trânsito. O estudo permitiu uma reflexão do contexto histórico recente da cidade de Palmas-TO.

Visual pollution is a phenomenon that should be discussed, as it directly affects the quality of life of citizens, the landscape and urban memory. The objective of the research was to map the visual pollution in urban spaces in Palmas-TO and compare it with the existing visual pollution in 2010 and 2021. The study was carried out through a photographic record of advertising pieces present in the 10 blocks of the symbolic center, in locations with a higher concentration of external media. The results show that wooden and metal billboards, small signs and banners were removed. In some places where the government managed to remove the billboards, the private sector incorporated advertising into its building structure. Ad-free metal billboards remain an unresolved issue in the city. No digital panels were found in the monitored locations. Over the 11 years of comparison, greater inspection by public bodies was observed. Public managers and civil society are encouraged to continuously monitor visual pollution. Researchers are encouraged to carry out studies that consider the influence of visual pollution on the occurrence of traffic accidents. The study allowed a reflection on the recent historical context of the city of Palmas-TO.
