Autoras marginales y subjetividades excéntricas en los espacios de la ciencia ficción sudamericana escrita por mujeres
Authors: Cortés Correa Macarena 
Published: July 2022

La ciencia ficción escrita por mujeres en Latinoamérica ha permanecido en los bordes del campo literario por su condición de triple marginalidad, debido a la apreciación de la ciencia ficción como un género menor respecto a aquellos canónicos promovidos desde la institucionalidad literaria, a la invisibilidad de la escritura de las mujeres en los medios literarios, y a la posición de América Latina como “Tercer Mundo” respecto a los países desarrollados.
Estos desplazamientos se materializan en las narraciones de muchas escritoras, en las que se construyen espacios liminales –callejones, basurales, alambradas, desiertos– donde los sujetos se ven atravesados por la frontera (Anzaldúa, 1987). Subjetividades excéntricas (De Lauretis, 2000) y cuerpos posthumanos (Haraway, 1995; Braidotti, 2015) subvierten los espacios delimitados por el sistema en estos relatos de ciencia ficción de la última década.

Authors: De Freitas Caetano Vinicius , Simões Teixeira A. Paula Priscila , Gomes de Souza Jr Fernando 
Published: July 2022

Separation processes with membranes stand out in applications for removing CO 2 from gaseous mixtures due to industrial, environmental and energy demands. The membrane must then be designed to allow high gas flow, high selectivity and chemical and mechanical stability under operating conditions of feed composition, pressure and temperature. Hybrid materials based on carbon materials - carbon nanotubes and graphene oxide - and polymers - cellulose acetate, polyamide, polyimide and polyether block amide - are presented as new types of studied membranes that present promising results in gas separation. An attempt to study a systematic analysis was carried out and despite not achieving adequate results in the literature, it is possible to infer a potential application of carbon nanotubes and graphene oxide in polymeric matrix as nanofillers that improve CO 2 removal.

Artiklen præsenterer resultaterne af en undersøgelse, der er pågået i UCNs efter- og videreuddannelsesafdeling i 2021. Formålet var at afdække betydningen af de asynkrone aktiviteter på diplom- og akademiuddannelserne. Undersøgelsen fokus på de læreprocesser, som opstår uden for de formaliserede undervisningsrammer, når planlagte, asynkrone aktiviteter kalder på refleksion med, i og over praksis.
Deltagerne i efter- og videreuddannelse er typisk voksne med arbejds- og familieliv, og som derfor har et ønske om geografisk og tidsmæssig fleksibilitet i forhold til uddannelse. Professionshøjskolen UCN har derfor interesse i at udvikle didaktiske designs, der afspejler fleksible, personlige og praksisnære løsninger til studerende i efter- og videreuddannelse.
20 studerende har deltaget i undersøgelsen, hvor det empiriske materiale er indsamlet via interviews, surveys og observationer af studieaktiviteten på læringsplatformen. Resultaterne viser, at når voksne studerende deltager i asynkrone læringsaktiviteter, skabes der ikke bare et geografisk og tidsmæssigt læringsrum, men et forlænget og flerspektivt refleksionsrum med tid og plads til at lære i eget tempo, på egne præmisser og i egen praksis. Det asynkrone læringsrum tilbyder desuden mangfoldige muligheder for inspiration, refleksion og konsolidering af ny viden. Det kræver grundig planlægning, stram styring og særlige underviserkompetencer at få optimal udnyttelse af det asynkrone rums læringspotentiale.

Published: July 2022

Osteoarthritis (OA) is the most seen form of arthritis, affecting a population of about 3.3 to 3.6% worldwide. In the ranking, it is the 11th most incapacitating disease worldwide, and in about a 43million people, it causes mild to severe disability. Estimated that 80% of the population In the United States over 65 years old have radiographic evidence of OA, although only 60-70% of this subset has symptoms. There were about 1 million hospitalizations for OA in 2011, with a cumulative cost of nearly $15 billion. This makes A the second most expensive disease seen in the United States [1, 2]. Secondary OA can affect older adults, and it could also affect younger people, usually those under 35 years of age.
Secondary OA has been regarded more as a mechanically-driven disease than an inflammatory disease. However, low-grade inflammation plays some part in cartilage degeneration and repair at many stages of arthropathy. In the past years, many published scientific papers on both animal models and human studies have indicated an increased role for both synovial inflammations and the activation of the membrane attack complexes of the complement system in the pathogenesis of secondary OA. There is also increasing evidence that significant risk factors for secondary OA have been linked with changes in systemic and local (at the articular cartilage chondrocyte level) cytokines and inflammatory mediators.
However, it remains controversial whether or not the inflammatory mediators are primary or secondary regulators of the damage to the cartilage or defective repair mechanisms present in secondary Osteoarthritis because the pathways for signaling involved in inflammatory and biomechanical stress are very much similar. So, these pathways could also induce and increase the expression of cytokine and chemokine genes.
Although research on the inflammatory mediators associated with Osteoarthritis has been done and much knowledge has been gained in the last decade, more studies are needed to define better the mechanisms by which these factors tip the balance between homeostasis and activation to promote cell death and matrix destruction. In response to stress and inflammatory insults, osteoarthritis chondrocytes produce a variety of matrix-degrading enzymes, including metalloproteinases and aggrecans. The expression of most of these enzymes of degradation is dysregulated in chondrocytes of patients with Osteoarthritis, and their increased activities and aberrant expression are the main contributors to cartilage degradation during osteoarthritis development and progression [3]. This student project aims to understand the role of inflammation in secondary Osteoarthritis.
Risk Factors Associated with the Prevalence of Fluorosis in the Endemic Area of Punjab (Bathinda District)
Authors: Grewal Vinaypreet , Singla Neerja 
Published: July 2022

Aim: To assess the risk factors associated with the prevalence of fluorosis in the endemic area of Punjab.
Study Design: The fluorosis endemic area of Punjab state was purposively selected for assessment of risk factors associated with it.
Place and Duration of Study: The study was conducted in rural and urban areas of Bathinda district during January 2021 to March 2021
Methodology: A sample of 140 subjects were selected randomly consisting of 70 males and 70 females each from both the rural and urban area of Bathinda district. An interview schedule cum questionnaire was designed to collect general, dietary and clinical information of the respondents. The degree of dental fluorosis was assessed using ICMR index [1].
Results: It was revealed that among the rural subjects, majority of respondents were suffering from grade 1 fluorosis (38.57%) followed by grade 0 (37.14%), grade 2 (18.57%) and grade 3 (5.71%). Whereas among urban subjects, majority of respondents were free from fluorosis (58.57%) followed by grade 2(34.28%), grade 1 (21.42%) and grade 3 (5.71%). Age and the duration of stay in the endemic area were found to be positively correlated with the incidence of fluorosis. The higher number of subjects having heavy or moderate lifestyle were suffering from grade 2 and grade 3 of fluorosis, whereas majority of sedentary respondents were free from fluorosis and suffering from grade 1 of fluorosis. A negative correlation was observed with the per capita income of the selected subjects, i.e., with the increasing income the prevalence of fluorosis decreased. Excessive intake of tea and alcohol was also associated with the severity of fluorosis. Among various micro nutrients, the intake of Calcium, phosphorus, magnesium and ascorbic acid was found to be significantly (P<0.05) different in the subjects with various grades of fluorosis.
Conclusion: Water is the primary source of fluorine intake by humans, but there are many predisposing factors that aggravate the condition for fluorosis, which can be avoided by taking diet rich in calcium and anti-oxidants in addition to water with permissible level of fluorine. The higher prevalence in the rural area as compared to urban area might be due to more consumption of tea and alcohol by respondents belonging to rural area.

Published: July 2022

Introduction: Numerous obesity indices have been developed that predict non-alcoholic fatty liver disease (NAFLD). We in our study aimed at evaluating a few of these tools including waist to height ratio (WHtR), waist circumferences (WC), body mass index (BMI) and fatty liver index (FLI) and used them to determine their ability in diagnosing NAFLD.
Methods: This cross sectional study was conducted at the outpatients’ department of our hospital. NAFLD was diagnosed on the basis of ultrasound abdomen. Anthropometric parameters like Height (in), weight(cm), WC (cm), BMI, WHtR were calculated and later the FLI (comprising of BMI,WC, triglyceride and gamma glutamyl transferase) was calculated. The Receiver operating characteristic analysis (ROC) was then conducted to determine the discriminatory ability and related cut-off points and a P value of ≤0.05 was taken as statiscally significant.
Results: A total of 300 participants were included and the prevalence of NAFLD was 44.8% in men and 54.8% in women. Univariate analysis reported statistical significant association of NAFLD with all of the applied indices (P = 0.00). The WHtR (AUC = 0.87, 95% CI:0.77-0.97) showed slight superior ability as compared to FLI (AUC = 0.86, 95% CI:0.76-0.97) in diagnosing NAFLD. Regression analysis revealed a stronger association of WHtR (OR = 9.3, P = 0.00) with NAFLD compared to FLI (OR = 6.0, P = 0.02).
The performance of WHtR was similar regardless of gender (AUC = 0.89) while different in FLI with a AUC of 0.88 in men and AUC of 0.85 in female.
Conclusion: This study showed a strong association of WHtR in prediction of NAFLD and a similar discriminatory ability regardless of gender. WHtR is simple and easily performable modality for NAFLD prediction.

Background: By the end of 2019, a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was diagnosed in Wuhan, Hubei province, China. In Saudi Arabia, the government applied prompt preventive measures against coronavirus disease 19 (COVID-19). COVID-19 associated restrictions have been affected the antenatal care (ANC) services that made careful surveillance of the pregnant women health requirement to protect them from COVID-19 infection. The current study was conducted to assess the COVID-19 pandemic effect on ante-natal care utilization among primigravida women in Asir region, Saudi Arabia.
Methods: A descriptive cross-sectional study was conducted targeting all females with their 1st pregnancy during COVID-19 pandemic. The questionnaire covered pregnant females’ demographic data, medical history, COVID-19 infection history, ante-natal care visits. Final questionnaire was distributed among woman attending antenatal care clinics at primary health care centres (PHCCs) and Abha Maternity and Children Hospital clinics in Asir region during the period from December 2020 to December 2021
Results: A total of 555 women attend to antenatal care clinics participated in the study. Primigravida women, who got pregnant during the COVID-19 pandemic were included. Exact of 114 primigravida women meet the inclusion criteria. Participants’ ages ranged from 21 to more than 40 years with mean age of 24.6 ± 9.4 years old. Ante-natal care visits of 1st pregnancy women during a period of quarantine in Asir regions. Exact of 90 (78.9%) pregnant females were compliant to ANC visits during COVID-19 pandemic. A total of 63 (70%) of these visits were in the private sector while 21 (23.3%) were at the governmental hospitals and 18 (6.7%) at the PHCCs.
Conclusion: The current study revealed that pregnant primigravida females were adequately adherent for the ANC visits during COVID-19 pandemic especially those with multiple pregnancies. The most settings provided ANC visits were the private sector with reported good pregnancy outcome.

Published: July 2022

ImportancePublic health services, including cancer screening tests, have been affected by the onset of the COVID-19 epidemic.ObjectiveTo investigate the pandemic’s association with cancer screening worldwide.Data SourcesIn this systematic review and meta-analysis, databases such as PubMed, ProQuest, and Scopus were searched comprehensively for articles published between January 1, 2020, and December 12, 2021.Study SelectionObservational studies and articles that reported data from cancer registries that compared the number of screening tests performed before and during the pandemic for breast, cervical, and colorectal cancer were included.Data Extraction and SynthesisTwo pairs of independent reviewers extracted data from the selected studies. The weighted average of the percentage variation was calculated between the 2 periods to assess the change in the number of cancer screening tests performed during the pandemic. Stratified analysis was performed by geographic area, period, and type of setting. The systematic review and meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.Main Outcomes and MeasuresThe main outcome was the weighted average percentage variation in the number of screening tests performed between January and October 2020 compared with the previous period.ResultsThe review comprised 39 publications. There was an overall decrease of −46.7% (95% CI, −55.5% to −37.8%) for breast cancer screening, −44.9% (95% CI, −53.8% to −36.1%) for colorectal cancer screening, and −51.8% (95% CI, −64.7% to −38.9%) for cervical cancer screening during the pandemic. For all 3 cancers, a U-shaped temporal trend was identified; for colorectal cancer, a significant decrease was still apparent after May 2020 (in June to October, the decrease was −23.4% [95% CI, −44.4% to −2.4%]). Differences by geographic area and screening setting were also identified.Conclusions and RelevanceA summary estimate of the downscaling of cancer screening tests since the onset of the COVID-19 pandemic is provided in this systematic review and meta-analysis. This could be associated with an increase in the number of avoidable cancer deaths. Effective interventions are required to restore the capacity of screening services to the prepandemic level.
Motivational and Valence‐Related Modulation of Sleep/Wake Behavior are Mediated by Midbrain Dopamine and Uncoupled from the Homeostatic and Circadian Processes
Authors: Fifel Karim , El Farissi Amina , Cherasse Yoan , Yanagisawa Masashi 
Published: July 2022

AbstractMotivation and its hedonic valence are powerful modulators of sleep/wake behavior, yet its underlying mechanism is still poorly understood. Given the well‐established role of midbrain dopamine (mDA) neurons in encoding motivation and emotional valence, here, neuronal mechanisms mediating sleep/wake regulation are systematically investigated by DA neurotransmission. It is discovered that mDA mediates the strong modulation of sleep/wake states by motivational valence. Surprisingly, this modulation can be uncoupled from the classically employed measures of circadian and homeostatic processes of sleep regulation. These results establish the experimental foundation for an additional new factor of sleep regulation. Furthermore, an electroencephalographic marker during wakefulness at the theta range is identified that can be used to reliably track valence‐related modulation of sleep. Taken together, this study identifies mDA signaling as an important neural substrate mediating sleep modulation by motivational valence.
Recent Advances in Nonfullerene Acceptor‐Based Layer‐by‐Layer Organic Solar Cells Using a Solution Process
Authors: Jee Min Hun , Ryu Hwa Sook , Lee Dongmin , Lee Wonho , Woo Han Young 
Published: July 2022

AbstractRecently, sequential layer‐by‐layer (LbL) organic solar cells (OSCs) have attracted significant attention owing to their favorable p–i–n vertical phase separation, efficient charge transport/extraction, and potential for lab‐to‐fab large‐scale production, achieving high power conversion efficiencies (PCEs) of over 18%. This review first summarizes recent studies on various approaches to obtain ideal vertical D/A phase separation in nonfullerene acceptor (NFAs)‐based LbL OSCs by proper solvent selection, processing additives, protecting solvent treatment, ternary blends, etc. Additionally, the longer exciton diffusion length of NFAs compared with fullerene derivatives, which provides a new scope for further improvement in the performance of LbL OSCs, is been discussed. Large‐area device/module production by LbL techniques and device stability issues, including thermal and mechanical stability, are also reviewed. Finally, the current challenges and prospects for further progress toward their eventual commercialization are discussed.

Published: July 2022

Abstract2D materials exhibit unique electrical and mechanical properties, and therefore have been investigated extensively. One of their important applications is logic‐in‐memory, which can perform logic operations as well as store data. This makes it possible to overcome the intrinsic obstacles of the von Neuman computing architecture that uses separate processing and storage units. Herein, a two‐terminal self‐gating random‐access memory (SGRAM) based on partially aligned graphene/MoS2/h‐BN/graphene/h‐BN/Au heterostructures is proposed. One of the two electrodes acts as the drain as well as the gate electrodes; thus, the SGRAM exhibits both diode‐like behaviors and nonvolatile memory effects, allowing the construction of a simple crossbar array without a selector. The SGRAM crossbar array consisting of 2 × 2 cells is constructed and its random accessibility is verified by addressing each cell independently. In addition, reconfigurable AND/OR logic gates are implemented using the SGRAM array. Hence, it is demonstrated that SGRAMs are promising candidates for “Beyond von Neumann” computing architectures.
