Abstract
BACKGROUND The airway epithelium is composed of diverse cell types with specialized functions that mediate homeostasis and protect against respiratory pathogens. Human airway epithelial (HAE) cultures at air-liquid interface are a physiologically relevant in vitro model of this heterogeneous tissue and have enabled numerous studies of airway disease. HAE cultures are classically derived from primary epithelial cells, the relatively limited passage capacity of which can limit experimental methods and study designs. BCi-NS1.1, a previously described and widely used basal cell line engineered to express hTERT, exhibits extended passage lifespan while retaining the capacity for differentiation to HAE. However, gene expression and innate immune function in BCi-NS1.1-derived versus primary-derived HAE cultures have not been fully characterized. METHODS BCi-NS1.1-derived HAE cultures (n = 3 independent differentiations) and primary-derived HAE cultures (n = 3 distinct donors) were characterized by immunofluorescence and single cell RNA-Seq (scRNA-Seq). Innate immune functions were evaluated in response to interferon stimulation and to infection with viral and bacterial respiratory pathogens. RESULTS We confirm at high resolution that BCi-NS1.1- and primary-derived HAE cultures are largely similar in morphology, cell type composition, and overall gene expression patterns. While we observed cell-type specific expression differences of several interferon stimulated genes in BCi-NS1.1-derived HAE cultures, we did not observe significant differences in susceptibility to infection with influenza A virus and Staphylococcus aureus. CONCLUSIONS Taken together, our results further support BCi-NS1.1-derived HAE cultures as a valuable tool for the study of airway infectious disease.

Abstract
Intrasaccular flow disruption is a viable alternative to other endovascular treatments for saccular or wide-necked bifurcation intracranial aneurysms; however, wide neck aneurysms with irregular shapes or shallow depth may not be amenable to treatment currently available intrasaccular devices. Here, we present the first ever case report of the novel Saccular Endovascular Aneurysm Lattice Embolization System (SEAL™). The versatile utility of the SEAL™ device is demonstrated in a patient with acute subarachnoid hemorrhage (SAH) from a ruptured, complex, left middle cerebral artery (MCA) trilobed shallow wide-necked bifurcation aneurysm. Deployment and implantation of the SEAL device were technically feasible, safe, and conformed well to the irregular shape of the complex, ruptured aneurysm. Immediate total aneurysm occlusion was observed after implantation. Importantly, 1-year angiographic follow-up demonstrated durable, complete occlusion with no safety concerns. The SEAL device is a promising new novel technology which has the potential to treat very shallow aneurysms with limited height and irregular, multilobulated aneurysms.

Abstract
Glassy solid electrolytes (GSEs) are promising solid electrolytes in the development of all solid-state batteries. Mixed oxy-sulfide nitride (MOSN) GSEs combine the high ionic conductivity of sulfide glasses, the excellent chemical stability of oxide glasses, and the electrochemical stability of nitride glasses. However, the reports on the synthesis and characterization of these novel nitrogen containing electrolytes are quite limited. Therefore, the systematic incorporation of LiPON during glass synthesis was used to explore the effects of nitrogen and oxygen additions on the atomic-level structures in the glass transition (Tg) and crystallization temperature (Tc) of MOSN GSEs. The MOSN GSE series 58.3Li2S + 31.7SiS2 + 10[(1 - x)Li0.67PO2.83 + x LiPO2.53N0.314], x = 0.0, 0.06, 0.12, 0.2, 0.27, 0.36, was prepared by melt-quench synthesis. Differential scanning calorimetry was used to determine the Tg and Tc values of these glasses. Fourier transformation-infrared, Raman, and magic angle spinning nuclear magnetic resonance spectroscopies were used to examine the short-range order structures of these materials. X-ray photoelectron spectroscopy was conducted on the glasses to further understand the bonding environments of the doped nitrogen. Finally, N and S elemental analyses were used to confirm the composition of these GSEs. These results are used to elucidate the structure of these glasses and to understand the thermal property impact oxygen and nitrogen doping in these GSEs.

Abstract
Throughout the years, wildfires have negatively impacted ecological systems and urban areas. Hence, reinforcing territorial risk management strategies against wildfires is essential. In this study, we built an early alert system (EAS) with two different Machine Learning (ML) techniques to calculate the meteorological conditions of two Colombian areas: (i) A 3D convolutional neural net capable of learning from satellite data and (ii) a convolutional network to bias-correct the Weather Research and Forecasting (WRF) model output. The results were used to quantify the daily Fire Weather Index and were coupled with the outcomes from a land cover analysis conducted through a Naïve-Bayes classifier to estimate the probability of wildfire occurrence. These results, combined with an assessment of global vulnerability in both locations, allow the construction of daily risk maps in both areas. On the other hand, a set of short-term preventive and corrective measures were suggested to public authorities to implement, after an early alert prediction of a possible future wildfire. Finally, Soil Management Practices are proposed to tackle the medium- and long-term causes of wildfire development, with the aim of reducing vulnerability and promoting soil protection. In conclusion, this paper creates an EAS for wildfires, based on novel ML techniques and risk maps.

Abstract
Abstract
Conventional antibodies (Abs) consist of two heavy and two light immunoglobulin chains, while heavy-chain only antibodies (HCAbs), like those found in camelid and shark species, are unique because they lack a light chain binding partner. The unique structure of these HCAbs impart advantageous properties to these smaller Abs, including greater accessibility to their target antigens, higher hydrophilicity, and greater conformational stability under environmental stresses. We have generated a mouse model, the IgG3dCH1 strain, that can produce HCAbs from the endogenous murine heavy chain locus. We have shown that these mice undergo efficient B cell development in the bone marrow, and generate a diverse repertoire of B cells that populate all peripheral immune compartments. While single-cell sequencing analysis of B cells revealed some biases in VH and JH usage, it also highlighted the tremendous diversity of rearrangements that give rise to B cells bearing these single chain antibodies. We’ve been able to show that upon immunization, IgG3dCH1 animals are protected from lethal bacterial challenge with a pathogenic strain of Enterobacter hormaechei and generate pathogen specific IgG. Further, immunization with SARS-CoV2 stabilized prefusion spike protein elicited HCAbs with a KD in the nM range, measured via bio-layer interferometry. These data support this mouse being utilized as a platform for the generation of pathogen-specific HCAbs that can be further engineered for testing and application for translational outcomes.

Abstract
The microbial populations in the gut microbiome have recently been associated with COVID-19 disease severity. However, a causal impact of the gut microbiome on COVID-19 patient health has not been established. Here we provide evidence that gut microbiome dysbiosis is associated with translocation of bacteria into the blood during COVID-19, causing life-threatening secondary infections. Antibiotics and other treatments during COVID-19 can potentially confound microbiome associations. We therefore first demonstrate that the gut microbiome is directly affected by SARS-CoV-2 infection in a dose-dependent manner in a mouse model, causally linking viral infection and gut microbiome dysbiosis. Comparison with stool samples collected from 101 COVID-19 patients at two different clinical sites also revealed substantial gut microbiome dysbiosis, paralleling our observations in the animal model. Specifically, we observed blooms of opportunistic pathogenic bacterial genera known to include antimicrobial-resistant species in hospitalized COVID-19 patients. Analysis of blood culture results testing for secondary microbial bloodstream infections with paired microbiome data obtained from these patients suggest that bacteria translocate from the gut into the systemic circulation of COVID-19 patients. These results are consistent with a direct role for gut microbiome dysbiosis in enabling dangerous secondary infections during COVID-19.

Abstract
Background:
Several genetic susceptibility risk loci for ischemic stroke have been identified. However, the relative dearth of genetic data from populations of non-European ancestry has the potential to create disparities in access to genomics-based precision medicine strategies. Individuals of Native Hawaiian ancestry represent a particularly understudied group in stroke genomics research despite facing high rates of cerebrovascular disease.
Hypothesis:
Genetic variants associated with stroke differ between Native Hawaiians and previously studied groups of predominantly European ancestry.
Methods:
We conducted a genome-wide (GW) association study of stroke and myocardial infarction (MI) in an adult population of Native Hawaiian ancestry, using data from the Multiethnic Cohort study (MEC). Genetic information was ascertained via genome-wide array genotyping using the AB OpenArray and TaqMan platforms followed by imputation to 1000 Genomes reference panels. We pursued replication of variants that were GW significant (p<5x10
-8
) or yielded suggestive associations (p<5x10
-7
) in the prior stroke GW association study MEGASTROKE.
Results:
We identified 2,104 individuals (1,089 [51.8%] female) of Native Hawaiian ancestry, including 173 cases and 1,931 controls. We identified one novel susceptibility risk locus at a narrow intronic region located at chromosome q26.2 (top associated SNP 3:169096251, OR 2.48, 95%CI 1.81-3.41; p=1.93x10
-8
), overlying the
MECOM
gene. We also identified 9 other suggestive risk loci at p<5x10
-7
. When replicating in MEGASTROKE, q26.2 did not have available counterpart variants to analyze, and 3 out of 9 suggestive signals were associated with ischemic stroke subtypes at p<0.05.
Conclusions:
We report the first GW association study of ischemic stroke and myocardial infarction in a Native Hawaiian population. We identified one susceptibility risk locus at q26.2, located in a narrow intronic region of
MECOM,
a gene that codes for a histone-lysine N-methyltransferase that has transcriptional regulation and oncoprotein functions. The lack of available replication data for this locus in the large MEGASTROKE collaboration emphasizes the importance of developing genomic resources across ancestral groups.

Abstract
BACKGROUND Laparoscopic liver resections (LLR) have been increasingly performed in recent years. Most of the available evidence, however, comes from specialized centers in Asia, Europe and USA. Data from South America are limited and based on single-center experiences. To date, no multicenter studies evaluated the results of LLR in South America. The aim of this study was to evaluate the experience and results with LLR in South American centers. METHODS From February to November 2019, a survey about LLR was conducted in 61 hepatobiliary centers in South America, composed by 20 questions concerning demographic characteristics, surgical data, and perioperative results. RESULTS Fifty-one (83.6%) centers from seven different countries answered the survey. A total of 2887 LLR were performed, as follows: Argentina (928), Brazil (1326), Chile (322), Colombia (210), Paraguay (9), Peru (75), and Uruguay (8). The first program began in 1997; however, the majority (60.7%) started after 2010. The percentage of LLR over open resections was 28.4% (4.4-84%). Of the total, 76.5% were minor hepatectomies and 23.5% major, including 266 right hepatectomies and 343 left hepatectomies. The conversion rate was 9.7%, overall morbidity 13%, and mortality 0.7%. CONCLUSIONS This is the largest study assessing the dissemination and results of LLR in South America. It showed an increasing number of centers performing LLR with the promising perioperative results, aligned with other worldwide excellence centers.

Abstract
It is known that reactive oxygen species (ROS) are accumulated within the oocyte during in vitro maturation (IVM) and have been related to poor quality and decreased embryo development in vitro. The use of antioxidants in culture media is an alternative to overcome oxidative stress damage in the oocyte. Resveratrol (3,5,4′-trihydroxy-trans-stilbene) is a phenol produced naturally by several plants and has shown protection against oxidative damage in numerous cell types. Two different experiments were performed to evaluate the effect of resveratrol on the quality of bovine oocytes matured in vitro assessed by levels of ROS and intracellular glutathione (GSH) as well as in vitro embryo development rates. Experiment 1 used different concentrations of resveratrol [0 (Control), 1 (R1), 10 (R10), 20 (R20), and 40 (R40) μM] were used to supplement IVM media. Ovaries were collected from Bos indicus cows at a local abattoir and cumulus-oocyte complexes were matured in vitro for 24 h in TCM199 with 6 mg mL−1 of fatty acid-free BSA, 5% fetal bovine serum, 0.2 mM Na-pyruvate, 50 μg mL−1 of gentamicin, 0.5 μg mL−1 of FSH, and 0.5 µg mL−1 of LH at 38°C in 5% CO2 and 90% humidity. The ROS were evaluated by 2′,7′-dichlorodihydrofluorescein diacetate staining (n = 301) and intracellular GSH levels were determined by Cell Tracker Blue fluorescent stain (n = 310). Denuded oocytes were observed under an epifluorescence microscope. Fluorescence intensities of oocytes were analysed by ImageJ software (Version 1.49v, National Institutes of Health, Bethesda, MD, USA) and normalized to control oocytes. Experiment 2 used cumulus-oocyte complexes (n = 674) collected and matured in vitro under the same conditions described for Exp. 1. In vitro fertilization was performed for 18 h at 38°C in 5% CO2 in Tyrode’s medium with 25 mM bicarbonate, 22 mM Na-lactate, 1 mM Na-pyruvate, and 6 mg mL−1 of fatty acid-free BSA. Additionally 10 µg mL−1 of heparin and 20 μM d-penicillamine, 10 μM hypotaurine, and 1 μM epinephrine were added. The presumptive zygotes were cultured in vitro in SOFaa medium with 5% fetal bovine serum, at 38°C, in 5% CO2, 5% O2, and 90% humidity until Day 7, when embryonic development was assessed. Data were analysed by ANOVA followed by Fisher´s multiple range test using Statgraphics Centurion XVI (Version 16.2.04, Statpoint Technologies Inc., Warrentown, VA). Data are presented as percentage mean ± standard error of the mean (P < 0.05). All concentrations of resveratrol in treated oocytes showed reduced intracellular levels of ROS compared to control (R1: 0.66 ± 0.04, R10: 0.55 ± 0.04, R20: 0.62 ± 0.04, R40: 0.64 ± 0.04, and Control: 1 ± 0.04 pixel/oocyte; P < 0.01). Intracellular levels of GSH were significantly higher for R1 (1.4 ± 0.06; P < 0.01) and R10 (1.3 ± 0.06; P < 0.01) compared with the control. On the other hand, R10 showed a significantly higher blastocyst rate (51% ± 3) compared with R1 (39% ± 4), R20 (39% ± 3), R40 (33% ± 3), and control (38% ± 4). Treatments R1, R20, and R40 showed no significant differences compared to control. These results indicate that resveratrol at 10 μM during IVM improves maturation conditions by decreasing ROS level, increasing intracellular GSH, and improving embryonic developmental competence.

Abstract
Lossy mode resonances (LMRs) and surface plasmon resonaces (SPRs) are obtained experimentally with a Kretschmann configuration using a BK7 glass prism with all sides polished and coated with indium tin oxide (ITO). The properties of ITO allow for obtaining LMRs and SPRs with the same experimental setup. The results are corroborated with a numerical method for calculation of the reflection in the Kretschmann configuration.

Abstract
Caveolins are a family of membrane proteins required for the formation of small plasma membrane invaginations called caveolae that are implicated in cellular trafficking processes. In addition to this structural role, these scaffolding proteins modulate numerous intracellular signaling pathways; often via direct interaction with specific binding partners. Caveolin-1 is particularly well-studied in this respect and has been attributed a large variety of functions. Thus, Caveolin-1 also represents the best-characterized isoform of this family with respect to its participation in cancer. Rather strikingly, available evidence indicates that Caveolin-1 belongs to a select group of proteins that function, depending on the cellular settings, both as tumor suppressor and promoter of cellular traits commonly associated with enhanced malignant behavior, such as metastasis and multi-drug resistance. The mechanisms underlying such ambiguity in Caveolin-1 function constitute an area of great interest. Here, we will focus on discussing how Caveolin-1 modulates cell death and survival pathways and how this may contribute to a better understanding of the ambiguous role this protein plays in cancer.

Abstract
AIM: To address endoscopic outcomes of post-Orthotopic liver transplantation (OLT) patients diagnosed with a “redundant bile duct” (RBD).
METHODS: Medical records of patients who underwent OLT at the Liver Transplant Center, University Texas Health Science Center at San Antonio Texas were retrospectively analyzed. Patients with suspected biliary tract complications (BTC) underwent endoscopic retrograde cholangiopancreatography (ERCP). All ERCP were performed by experienced biliary endoscopist. RBD was defined as a looped, sigmoid-shaped bile duct on cholangiogram with associated cholestatic liver biomarkers. Patients with biliary T-tube placement, biliary anastomotic strictures, bile leaks, bile-duct stones-sludge and suspected sphincter of oddi dysfunction were excluded. Therapy included single or multiple biliary stents with or without sphincterotomy. The incidence of RBD, the number of ERCP corrective sessions, and the type of endoscopic interventions were recorded. Successful response to endoscopic therapy was defined as resolution of RBD with normalization of associated cholestasis. Laboratory data and pertinent radiographic imaging noted included the pre-ERCP period and a follow up period of 6-12 mo after the last ERCP intervention.
RESULTS: One thousand two hundred and eighty-two patient records who received OLT from 1992 through 2011 were reviewed. Two hundred and twenty-four patients underwent ERCP for suspected BTC. RBD was reported in each of the initial cholangiograms. Twenty-one out of 1282 (1.6%) were identified as having RBD. There were 12 men and 9 women, average age of 59.6 years. Primary indication for ERCP was cholestatic pattern of liver associated biomarkers. Nineteen out of 21 patients underwent endoscopic therapy and 2/21 required immediate surgical intervention. In the endoscopically managed group: 65 ERCP procedures were performed with an average of 3.4 per patient and 1.1 stent per session. Fifteen out of 19 (78.9%) patients were successfully managed with biliary stenting. All stents were plastic. Selection of stent size and length were based upon endoscopist preference. Stent size ranged from 7 to 11.5 Fr (average stent size 10 Fr); Stent length ranged from 6 to 15 cm (average length 9 cm). Concurrent biliary sphincterotomy was performed in 10/19 patients. Single ERCP session was sufficient in 6/15 (40.0%) patients, whereas 4/15 (26.7%) patients needed two ERCP sessions and 5/15 (33.3%) patients required more than two (average of 5.4 ERCP procedures). Single biliary stent was sufficient in 5 patients; the remaining patients required an average of 4.9 stents. Four out of 19 (21.1%) patients failed endotherapy (lack of resolution of RBD and recurrent cholestasis in the absence of biliary stent) and required either choledocojejunostomy (2/4) or percutaneous biliary drainage (2/4). Endoscopic complications included: 2/65 (3%) post-ERCP pancreatitis and 2/10 (20%) non-complicated post-sphincterotomy bleeding. No endoscopic related mortality was found. The medical records of the 15 successful endoscopically managed patients were reviewed for a period of one year after removal of all biliary stents. Eleven patients had continued resolution of cholestatic biomarkers (73%). One patient had recurrent hepatitis C, 2 patients suffered septic shock which was not associated with ERCP and 1 patient was transferred care to an outside provider and records were not available for our review.
CONCLUSION: Although surgical biliary reconstruction techniques have improved, RBD represents a post-OLT complication. This entity is rare however, endoscopic management of RBD represents a reasonable initial approach.

Abstract
The deposition of silver nanoparticles on the surface of silica was carried out using our simple, robust and rapid chemical method without surface modification of silica or added coupling agents. The process was carried out at room temperature using water/methanol mixtures, tetraethyl orthosilicate as Si source and silver nanoparticles (NPs) in a single-pot reaction. Using EDS, XRD, HRTEM and High Angle Annular Dark Field (HAADF) STEM characterization techniques, we have found the coexistence of silver NPs and silver oxides NPs anchored to the surface of sub-micron silica spheres, with Ag NPs predominating sizes around 2-3 nm approximately, and Ag2O NPs sizes over 10 nm.

Abstract
Transient elastography is a useful method to assess liver fibrosis, but uncertainties still exist regarding reliability and reproducibility of the technique. We aimed to improve knowledge on interobserver variability with the procedure and tried to find factors associated with such variability. This was a cross-sectional study to compare the results of transient elastography performed by two different operators, one test made just after the other. We assessed both results with correlation tests and with repeated parametric or nonparametric tests, as needed. We also carried out a multivariate analysis to find factors associated with discrepancy in the results obtained by the two operators. We included a total of 333 pairs of transient elastography tests, belonging to 274 different patients. A total of 325 pairs of tests (97.6%) were valid. Results of the first and the second tests were, respectively, median (and interquartile range) of direct measurement 6.2 (4.6-10.6) and 6.0 (4.4-10.1) kPa (P = 0.012), and mean ± standard deviation of log(10) of direct measurement 0.892 ± 0.316 and 0.871 ± 0.324 (P = 0.001). In 87 pairs of tests (26.7%), a discrepancy of at least 2 kPa between both results was found, and in 15 pairs of tests (4.6%), a discrepancy of at least 10 kPa was found. Discordance of at least one stage between both measurements was noted in 74 pairs of tests (22.8%). An association was found between higher stiffness and discrepancy between both operators (P < 0.001). Although transient elastography is a very convenient test to assess liver fibrosis in clinical practice, interobserver discrepancy in results is common and represents a significant problem with the technique. Discrepant results are more common in patients with higher values of stiffness.

Abstract
OBJECTIVE The purpose of this study was to analyze change of lifestyle in obese patients with cognitive behavior therapy and acupressure. METHODS An experimental study was performed with placebo control group. Forty patients were randomly assigned to intervention group (cognitive behaviour therapy + acupressure) and control group (information session). Outcome measure was a questionnaire for the assessment and quantification of obesity related lifestyles. Measures were performed at baseline and, after 3-months intervention. RESULTS After 3 months of treatment, the intervention group showed significant differences (p<0.05) in weight loss, diet and physical activity. CONCLUSION In the obese patient, cognitive behavior therapy and acupressure, it has lost at least three kilograms over three months and has changed lifestyles related to obesity.

Abstract
Microglia are important innate immune effectors against invading CNS pathogens, such as Staphylococcus aureus (S. aureus), a common etiological agent of brain abscesses typified by widespread inflammation and necrosis. The NLRP3 inflammasome is a protein complex involved in IL-1β and IL-18 processing following exposure to both pathogen- and danger-associated molecular patterns. Although previous studies from our laboratory have established that IL-1β is a major cytokine product of S. aureus-activated microglia and is pivotal for eliciting protective anti-bacterial immunity during brain abscess development, the molecular machinery responsible for cytokine release remains to be determined. Therefore, the functional role of the NLRP3 inflammasome and its adaptor protein apoptosis-associated speck-like protein (ASC) in eliciting IL-1β and IL-18 release was examined in primary microglia. Interestingly, we found that IL-1β, but not IL-18 production, was significantly attenuated in both NLRP3 and ASC knockout microglia following exposure to live S. aureus. NLRP3 inflammasome activation was partially dependent on autocrine/paracrine ATP release and α- and γ-hemolysins produced by live bacteria. A cathepsin B inhibitor attenuated IL-β release from NLRP3 and ASC knockout microglia, demonstrating the existence of alternative inflammasome-independent mechanisms for IL-1β processing. In contrast, microglial IL-18 secretion occurred independently of cathepsin B and inflammasome action. Collectively, these results demonstrate that microglial IL-1β processing is regulated by multiple pathways and diverges from mechanisms utilized for IL-18 cleavage. Understanding the molecular events that regulate IL-1β production is important for modulating this potent proinflammatory cytokine during CNS disease.

Abstract
BACKGROUND Measurement of far wall common carotid artery intima-media thickness (CCAIMT) has emerged as a predictor of incident cardiovascular events. The Cardiovascular Risk Factor Multiple Evaluation in Latin America (CARMELA) study was the first large-scale population-based assessment of both CCAIMT and cardiovascular risk factor prevalence in 7 Latin American cities; the relationship between CCAIMT and cardiovascular risk markers was assessed in these urban Latin American centers. METHODS CARMELA was a cross-sectional, population-based, observational study using stratified, multistage sampling. The participants completed a questionnaire, were evaluated in a clinical visit and underwent carotid ultrasonography. Clinical measurements were obtained by health personnel trained, certified and supervised by CARMELA investigators. Mannheim intima-media thickness consensus guidelines were followed for measurement of CCAIMT. RESULTS In all cities and for both sexes, CCAIMT increased with higher age. CCAIMT was greater in the presence of cardiovascular risk factors than in their absence. In all cities, there was a statistically significant linear trend between increasing CCAIMT and a growing number of cardiovascular risk factors (p < 0.001). After adjustment for age and sex, metabolic syndrome was strongly associated with increased CCAIMT (p < 0.001 in all cities), as were hypercholesterolemia, obesity and diabetes (p < 0.001 in most cities). By multivariate analysis, hypertension was independently associated with an increase in CCAIMT in all cities (p < 0.01). CONCLUSIONS CARMELA was the first large-scale population study to provide normal CCAIMT values according to age and sex in urban Latin American populations and to show CCAIMT increases in the presence of cardiovascular risk factors and metabolic syndrome.
