Authors: M G Benavidez
Published: June 2024

INTRODUCCIÓN: Los cambios de hábitos alimentarios orientados a consumir más vegetales y sustituir proteínas animales por vegetales generaron un aumento de consumidores vegetarianos y veganos1, como así también, el denominado flexitariano (quienes prefieren alimentos vegetales a los cárnicos, bajo el lema de alimentación saludable y sustentable con menor impacto ambiental)2. En línea a esta tendencia, Molino Chacabuco SA desarrolló un ingrediente para consumo masivo e industrial en el segmento de farináceos.
MATERIAL Y MÉTODOS: Se tomó como punto de inicio el perfil nutricional de la harina de trigo tipo 000 y evaluaron las diferentes opciones de mezclas con otras harinas para mejorar el perfil nutricional con foco en la funcionalidad. Se trabajó sobre harina integral de trigo y harina de legumbres. La mejora del perfil nutricional se basó en el aumento del valor proteico y fibra3. Para la funcionalidad se buscó que, tanto en consumo hogareño como en producción industrial, la harina se adapte a todo tipo de proceso de elaboración de alimentos.
RESULTADOS: La mezcla de 80% harina integral de trigo con 20% de harinas de garbanzo, lenteja, arveja y poroto negro mejora el perfil nutricional si se compara con la harina de trigo tipo 000. Aumenta 35% la proteína cruda (Figura 1) y 3.7 veces la fibra dietaría (Figura 2), disminuye 17% los carbohidratos, 5% el valor calórico y aporta 1.2% de Omega 6.
Los resultados de funcionalidad de consumidores finales que usaron la harina en recetas hogareñas fueron satisfactorios por su adaptabilidad. También se utilizó en línea industrial automática para panes de molde con buena respuesta a las exigencias del proceso.
CONCLUSIONES: La sustitución de harina de trigo 000 por harina integral de trigo más harina de legumbres mejora el perfil nutricional de los alimentos plant based aumentando el aporte de proteína vegetal y contenido de fibra.

Background: Rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy remains the standard of first-line treatment for diffuse large B-cell lymphoma (DLBCL). Up to 40% of DLBCL is characterized by relapse and refractory after treatment. Preliminary study reported Hypoxia-inducible factor-1? (HIF-1?) overexpression in 88.5% of DLBCL tumors in the Dr. Kariadi Hospital. Moreover, the role of hypoxia and HIF-1? has previously never been explored in DLBCL. Objectives: To evaluate the effect of hypoxia modulation to increased chemotherapeutic response in DLBCL. Methods: Single blind randomized control study was performed, with pre-test and post-test control group design. Research sampling consisted of DLBCL patients. The inclusion criteria include newly diagnosed DLBCL with HIF-1? overexpression and randomized to receive hypoxia modulation consisting of carbogen inhalation and nicotinamide administration, before R-CHOP chemotherapy. The tissue biopsy, histopathology and immunohistochemical studies were done. Chemotherapeutic responses were evaluated after 10-14 days following the first cycle of R-CHOP chemotherapy. Results: Out of twenty-six DLBCL participants with HIF-1? overexpression, there were 20 participants who completed the research protocol: 10 participants each in the intervention and control group. Demographic, clinicopathological, laboratory and disease characteristics were not statistically different between the two research groups (p>0.05). Baseline tumor volume to be evaluated was also considered equal (172.3 cm3 vs. 152.8 cm3, p=0.597). Following the carbogen inhalation and nicotinamide administration, serum HIF-1? and lactate reduction can be observed. There was also a significant tumor volume shrinkage in both the intervention and control (mean ?85.7 cm3 vs. ?118.27 cm3) group, though the reduction was not statistically different (Delta 58.85% vs. 65.63%, p=0.474). Conclusion: The addition of hypoxia modulation to R-CHOP chemotherapy for DLBCL has shown beneficial effects on both serum HIF-1? and lactate concentration. However, the benefits did not correlate to increase a better tumor response compared to the control group.

Published: June 2024

The present work investigates the mechanical properties of surface-modified magnesium alloy AZ61 reinforced with Al2O3 and TiO2 nanoparticles by using the friction stir processing (FSP) technique. Surface-modified AZ61 alloys were fabricated by the addition of dufferent amount of Al2O3 and TiO2 nanoparticles (5, 10, and 15 vol.%). The developed surface composites were studied regarding microstructure, revealing a uniform dispersion of the added nanoparticles, which resulted in improved mechanical properties of the obtained composites by FSP. The ultimate tensile strength, impact strength, and microhardness improved by 20, 45, and 67 % by reinforcing the alloy with nanoTiO2 particles when compared to the as-cast alloy. The results of this study indicate that the reinforced AZ61 Mg alloy can be a potential material for applications in automobile sectors due to its high strength and lightweight components.

Authors: Dhiman Monika , Upmanyu Arun , Singh Devinder , Juglan Kailash
Published: June 2024

In the present study, the ultrasonic velocity and density data for the binary mixture of polyethylene glycol (PEG)-400 and dimethyl sulfoxide (DMSO), at various concentrations and different temperatures (T, 288.15, 298.15 and 308.15 K), have been measured and further apllied to determine several physical parameters such as adiabatic and isothermal compressibility, intermolecular free length, internal pressure and free volume. The excess values of these parameters have also been computed and fitted with the Redlich? Kister (R?K) polynomial equation. The nature, type, and strength of intermolecular interactions present within the PEG-400 + DMSO mixture have been explained based on the sign and magnitude of excess values. Furthermore, partial molar volumes, excess partial molar volumes, apparent molar volumes and apparent molar volumes at infinite dilution have also been determined to investigate the solute?solvent interactions. Various mixing rules such as the ideal mixing rule (Uim), Nomoto relation (UN), impedance dependence relation (UZ), Junjie relation (UJ), van Deal?Vangeel relation (UV) and collision factor theory (UCFT) are employed to compute the ultrasonic velocity and compared with the experimental one. Among these relations, the Nomoto and Junjie relations are found to be most suitable for the given mixture. In addition to it, the present system has also been examined using Fourier transform infra-red (FTIR) and UV?Vis spectroscopic techniques. The change in intensity and shift in peak position in the FTIR and UV?Vis spectra of the PEG-400 + DMSO mixture are used to confirm the intermolecular hydrogen bonding in the given system.

Published: June 2024

The synthesis of four N-2-alkylated aza-galactofagomine (AGF) analogues was achieved by intermolecular reductive hydrazination or alkylation of suitably protected AGF. The synthesized compounds were evaluated as potential ?-glucosidase inhibitors. The preliminary screening of inhibitor activity, conducted with sweet almond ?-glucosidase immobilized in agar, as well as the standard inhibition assay with the same enzyme, showed the inhibitory potency of the synthesized analogues. In addition, these results are in a good agreement with the docking analysis of the human acid ?-glucosidase, the enzyme implicated in Gaucher?s disease.

Published: June 2024

OBJECTIVE

In this study we examine whether hospitalized coronavirus disease 2019 (COVID-19) pneumonia increases long-term cardiovascular mortality more than other hospitalized pneumonias in people with type 2 diabetes and aim to quantify the relative cardiovascular disease (CVD) mortality risks associated with COVID-19 versus non-COVID-19 pneumonia.

RESEARCH DESIGN AND METHODS

With use of the SCI-Diabetes register, two cohorts were identified: individuals with type 2 diabetes in 2016 and at the 2020 pandemic onset. Hospital and death records were linked for determination of pneumonia exposure and CVD deaths. Poisson regression estimated rate ratios (RRs) for CVD death associated with both pneumonia types, with adjustment for confounders. Median follow-up durations were 1,461 days (2016 cohort) and 700 days (2020 cohort).

RESULTS

The adjusted RR for CVD death following non-COVID-19 pneumonia was 5.51 (95% CI 5.31–5.71) prepandemic and 7.3 (6.86–7.76) during the pandemic. For COVID-19 pneumonia, the RR was 9.13 (8.55–9.75). Beyond 30 days post pneumonia, the RRs converged, to 4.24 (3.90–4.60) for non-COVID-19 and 3.35 (3.00–3.74) for COVID-19 pneumonia, consistent even with exclusion of prior CVD cases.

CONCLUSIONS

Hospitalized pneumonia, irrespective of causal agent, marks an increased risk for CVD death immediately and over the long-term. COVID-19 pneumonia poses a higher CVD death risk than other pneumonias in the short-term, but this distinction diminishes over time. These insights underscore the need for including pneumonia in CVD risk assessments, with particular attention to the acute impact of COVID-19 pneumonia.

Published: June 2024

Background: The Acute Disease Quality Initiative advocates multidisciplinary care for the survivors of acute kidney injury (AKI). The bundled care strategy recognizes the role of pharmacists. However, their specific contributions in this context remain underexplored. Methods: This retrospective study examined the efficacy of pharmacist-led post-AKI pharmaceutical care in outpatient settings at a single center. Adults with recent AKI during hospitalization, maintaining an estimated glomerular filtration rate <45 mL/min/1.73 m2 postdischarge, were enrolled in a multidisciplinary team care program from March 2022 to January 2023, with a 6-month follow-up period. Pharmacist-delivered care adhered to international multidisciplinary consensus guidelines. Efficacy was evaluated by analyzing medication-related recommendations, medication adherence, nephrotoxic drug utilization, and renoprotective medication usage before and after the intervention. Results: A total of 40 patients were referred to the pharmacist-managed clinic. Of these, 33 patients (mean age, 63 ± 15 years; 60.6% male) attended the clinic. Nineteen patients completed follow-up visits. The pharmacist provided 14 medication-related recommendations to relevant physicians, with 10 of these recommendations (71.4%) being accepted. There was a significant decrease in the use of modifiable nephrotoxic drugs (p = 0.03). However, no significant improvements were noted in medication adherence or the utilization of renoprotective medications. Conclusion: Our study underscores the potential benefits of pharmacist-led post-AKI bundled care strategy in outpatient settings. We observed a significant reduction in the utilization of modifiable nephrotoxic drugs, indicating the effectiveness of pharmacist interventions in optimizing medication regimens to mitigate renal harm.

Published: June 2024

Background: This study investigated the association between serum phosphate level and mortality in acute kidney injury (AKI) patients undergoing continuous kidney replacement therapy (CKRT) and evaluated whether this association differed according to disease severity. Methods: Data from eight tertiary hospitals in Korea were retrospectively analyzed. The patients were classified into four groups (low, normal, high, and very high) based on their serum phosphate level at baseline. The association between serum phosphate level and mortality was then analyzed, with further subgroup analysis being conducted according to disease severity. Results: Among the 3,290 patients identified, 166, 955, 1,307, and 862 were in the low, normal, high, and very high phosphate groups, respectively. The 90-day mortality rate was 63.9% and was highest in the very high group (76.3%). Both the high and very high groups showed a significantly higher 90-day mortality rate than did the normal phosphate group (high: hazard ratio [HR], 1.35, 95% confidence interval [CI], 1.21–1.51, p < 0.001; very high: HR, 2.01, 95% CI, 1.78–2.27, p < 0.001). The low group also exhibited a higher 90-day mortality rate than did the normal group among those with high disease severity (HR, 1.47; 95% CI, 1.09–1.99; p = 0.01) but not among those with low disease severity. Conclusion: High serum phosphate level predicted increased mortality in AKI patients undergoing CKRT, and low phosphate level was associated with increased mortality in patients with high disease severity. Therefore, serum phosphate levels should be carefully considered in critically ill patients with AKI.

Published: June 2024

Implementing social studies learning for grade 1 elementary school is still not optimal in absorbing material concepts and people's values in social studies lessons. One of the causes is the low quality of teaching modules teachers own. This research aims to develop a social studies e-module containing Balinese folklore based on Pancasila student profiles for grade 1 students in elementary schools. This research uses the Dick and Carey development model, which consists of 10 stages. The subject of this research is to use individual trials of 3 students and small group trials of 9 people. This research applies a post-test-only method with data collection methods using questionnaires and multiple-choice objective tests. Data analysis involves qualitative and quantitative descriptive analysis techniques. The research showed that the e-module obtained a very good classification with media validity of 80%, social studies content validity of 95%, design validity of 97.22%, language validity of 90%, individual trials of 91.67%, and small group trials amounting to 91.67%. The effectiveness calculation shows a significance value of 0.000 (< 0.05), confirming a significant difference in student understanding between classes that use e-modules containing Balinese folklore with Pancasila student profiles and classes that use regular e-modules. Thus, it is known that the new features in the e-module have proven effective in improving the quality of the learning process. This research can be used as a parameter for e-module development to support the feasibility and effectiveness of implementing learning for elementary school students.

In this work, we are interesting in solving the 1D and 2D nonlinear stiff reaction-diffusion Brusselator system using a machine learning technique called Physics-Informed Neural Networks (PINNs). PINN has been successful in a variety of science and engineering disciplines due to its ability of encoding physical laws, given by the PDE, into the neural network loss function in a way where the network must not only conform to the measurements, initial and boundary conditions, but also satisfy the governing equations. The utilization of PINN for Brusselator system is still in its infancy, with many questions to resolve. Performance of the framework is tested by solving some one and two dimensional problems with comparable numerical or analytical results. Validation of the results is investigated in terms of absolute error. The results showed that our PINN has well performed by producing a good accuracy on the given problems.

The article considers the effect of transformation of statistical distributions of concrete strength and deformation characteristics under the influence of freezing and thawing cycles (FTC) on the load-bearing capacity of the bent reinforced concrete element under variable longitudinal reinforcement. Using the probabilistic approach, the influence of the nature of the reinforcement of the bent reinforced concrete element on the dynamics of its bearing capacity in the process of FTC is evaluated. It is substantiated that the reduction of the load-bearing capacity of reinforced concrete beams as a result of the impact of FTC depends on the nature of the reinforcement. There are offered some proposals for the construction of reinforced concrete beams operated in conditions of cold climate.

Este texto aborda la problemática sobre las formas de historizar las prácticas escénicas en tanto acontecimientos efímeros, atravesados por lo corporal. Si estos son en apariencia irrecuperables una vez sucedidos, ¿desde qué voces podemos construir sus historias?, ¿qué materiales conforman sus archivos?, ¿qué lugar ocupa el cuerpo y la memoria? Luego de los primeros acercamientos a los archivos personales de tres artistas escénicas platenses —Laura Valencia, Nora Oneto, Carolina Donnantuoni— se propone pensar aquellos restos documentales de acontecimientos escénicos pasados como fuentes fundamentales para construir las historias de las artes escénicas locales desde una perspectiva crítica, situada y afectiva y asimismo reflexionar acerca de las maneras de mirar al pasado que habilitan estos conjuntos de materiales, memorias corporalizadas y relatos singulares.

Authors: Jauch Linzy , Labadie Julia , Swafford Brenna , Rao Sangeeta
Published: June 2024

OBJECTIVE

To identify the preferred choices of antimicrobials by veterinarians for addressing infectious diseases in Golden Retrievers across the US.

ANIMALS

3,044 Golden Retrievers enrolled in the Golden Retriever Lifetime Study.

METHODS

Demographic and veterinary visit data were retrieved from the Morris Animal Foundation Golden Retriever Lifetime Study, following 3,044 Golden Retrievers spanning from 2012 to 2020 collected through questionnaires. The R Studio program was used to clean and analyze the data in which the most common diagnoses were evaluated along with the most frequently used antimicrobials stratified by geographical region within the US.

RESULTS

The most common diagnoses reported and treated with antimicrobials were otitis externa, diarrhea/gastritis, hot spots, and bladder infections. Otitis externa was the most frequently reported medical diagnosis as well as prescribed with antibiotics. The Southern region reported the most antimicrobial use, followed by the Midwest and Northeast. Of the total reported antibiotics prescribed for infectious disease, aminoglycosides were the most frequent (370/1,874 [19.74%]) followed by first-generation cephalosporins, nitroimidazoles, and penicillins.

CLINICAL RELEVANCE

More effort in the prevention of otitis externa in Golden Retrievers may reduce overall antimicrobial usage and promote effective antimicrobial stewardship to combat further antimicrobial resistance.

Published: June 2024

The focus of this study is to propose statistical models for predicting wear and coefficient of friction of the 16MnCr5 steel valve tappet using the analysis of variance (ANOVA). The 16MnCr5 steel valve tappet was fabricated from a steel strip and thermochemically treated by carburizing, quenching, and tempering. Under dry conditions, tribological tests were performed for 16MnCr5 steel valve tappet with a ball-on-plane configuration in a reciprocating slide using an Optimol SRV® v4 device. Subsequently, the results of the coefficient of friction (COF) and the wear rate were then analyzed using the ANOVA. Regression analysis was used to derive the predictive equations for both friction coefficient and wear rate. The applied load was found to be the most significant parameter affecting the COF and wear rate. The proposed statistical models has 88 - 92% percent reliability. These models can be beneficial for predicting the tribological operating conditions for the 16MnCr5 steel valve tappet to avoid premature failure within the tested load and temperature conditions.

Authors: Sahab Marwan Mizher , Majeed Nahida Taha
Published: June 2024

The present study aims at designing ESP syllabus for teaching English to the second-year students, at the Department of Art Education, College of Education for Humanities/ University of Tikrit. The designed ESP syllabus is designed to improve the level of the students in English by supporting many practice opportunities such as,  gaining basic Art vocabulary, using language functions, motivating the students to express their points of view, giving the students opportunities to do many tasks, and encouraging them to engage in pair and group discussions. The designed ESP syllabus is built in terms of Nunan Model (1988) procedures, which includes: identification of students’ needs, selection of the syllabus content, deriving the objectives of the proposed syllabus, sequencing and grading of syllabus items and evaluating the proposed syllabus    The sample of the present study includes forty second-year university students from the Department of Art Education, College of Education for Humanities / University of Tikrit for the academic year 2021-2022. The involved sample represents 20 % of its original population. The One-group Pretest-Posttest Design is adopted in the current study.      In order to measure the effectiveness of the designed ESP syllabus, three basic tools are used. First, pre and posttests are utilized to measure the students' achievement in English. Second, a questionnaire is constructed to check the students’ views and reflections towards the designed ESP syllabus. Third, a questionnaire is administrated to estimate the lecturers’ and specialists’ points of view about the efficiency of the designed ESP syllabus.        Results indicate that there is a significant difference between the students’ achievement in the pretest and the posttest, and in favour of the posttest. That is  because the students have received art content-based lessons in which they have obtained art knowledge and a lot of basic art expressions ,  and became able to construct and use English properly especially in art situations.  Results of the questionnaire also indicate that students’ points of view are in favour of the designed ESP syllabus.  In addition, it seems that lecturers’ and specialists’ points of views are in favour of the items, objectives, and the content of the designed ESP syllabus. Finally, the study ends with some conclusions and recommendations.

India has been actively involved in the follow-up observations of optical afterglows of gamma-ray bursts (GRBs) for more than two decades, using the country’s meter-class facilities such as the 1.04m Sampurnanand Telescope, 1.3m Devasthal Fast Optical Telescope, 2.01 m Himalayan Chandra Telescope along with many others in the country, utilizing the longitudinal advantage of the place. However, since 2016, Indian astronomers have embarked on a new era of exploration by utilizing the country’s largest optical telescope, the 3.6-m Devasthal Optical Telescope (DOT) at the Devasthal Observatory of ARIES Nainital. This unique telescope has opened up exciting opportunities for transient study. Starting from the installation itself, the DOT has been actively performing the target of opportunity (ToO) observations, leading to many interesting discoveries. Notable achievements include the contributions towards the discovery of long GRB 211211A arising from a binary merger, the discovery of the most delayed optical flare from GRB 210204A along with the very faint optical afterglow (fainter than 25 mag in g-band) of GRB 200412B. We also successfully observed the optical counterpart of the very-high-energy (VHE) detected burst GRB 201015A using DOT. Additionally, DOT has been used for follow-up observations of dark and orphan afterglows, along with the observations of host galaxies associated with peculiar GRBs. More recently, DOT’s near-IR follow-up capabilities helped us to detect the first near-IR counterpart (GRB 230409B) using an Indian telescope. In this work, we summarise the recent discoveries and observations of GRBs using the 3.6-m DOT, highlighting the significant contributions in revealing the mysteries of these cosmic transients.
