Published: November 2023

Background:

Colorectal cancer (CRC) is a highly widespread malignancy and ranks as the second
most common cause of cancer-related mortality.

Objective:

Cancer patients, including those with CRC, who undergo chemotherapy, are often treated with platinum-
based anticancer drugs such as oxaliplatin (OXA). Nevertheless, the administration of OXA is associated
with a range of gastrointestinal problems, neuropathy, and respiratory tract infections. Hence, it is necessary
to devise a potential strategy that can effectively tackle these aforementioned challenges. The use of nanocarriers
has shown great potential in cancer treatment due to their ability to minimize side effects, target drugs
directly to cancer cells, and improve drug efficacy. Furthermore, numerous studies have been published regarding
the therapeutic efficacy of nanoparticles in the management of colorectal cancer.

Methods:

In this review, we present the most relevant nanostructures used for OXA encapsulation in recent
years, such as solid lipid nanoparticles, liposomes, polysaccharides, proteins, silica nanoparticles, metal nanoparticles,
and synthetic polymer-carriers. Additionally, the paper provides a summary of the disadvantages and
limits associated with nanoparticles.

Results:

The use of different carriers for the delivery of oxaliplatin increased the efficiency and reduced the
side effects of the drug. It has been observed that the majority of research investigations have focused on liposomes
and polysaccharides.

Conclusion:

This potentially auspicious method has the potential to enhance results and enhance the quality of
life for cancer patients undergoing chemotherapy. However, additional investigation is required to ascertain
the most suitable medium for the transportation of oxaliplatin and to assess its efficacy through clinical trials.

Published: November 2023

The exploration of nanocrystal technology is currently receiving significant attention in
various fields, including therapeutic formulation, clinical formulation, in-vivo and in-vitro correlation
research, and related investigations. The domain of nanocrystals in pharmaceutical delivery has received
significant interest as a potential solution for the difficulties associated with medications that
have low solubility. The nanocrystals demonstrate promise in improving solubility and bioavailability,
presenting a potential resolution to significant challenges. Significantly, nanocrystals have exhibited
efficacy in the context of oral administration, showcasing prompt absorption due to their quick
breakdown, hence fitting with the requirements of medications that necessitate fast commencement
of action. In addition, the adaptability of drug nanocrystals encompasses several methods of administration,
including oral, parenteral, ophthalmic, cutaneous, pulmonary, and targeted delivery modalities.
The observed consistency can be ascribed to the increased solubility of nanocrystals of the medicine,
which effectively counteracts the influence of food on the absorption of the drug. Surface modification
tactics have a significant influence on insoluble medicines by enhancing hydrophilicity and
reducing plasma protein adsorption on the crystal surface. The surface properties of nanocrystals are
modified through the utilization of specific surfactants and polymers, which are subsequently incorporated
into polymer solutions via high-pressure homogenization procedures. This article encompasses
an examination of the drug distribution mechanism, the nanocrystal formulation technology,
the therapeutic applications, the potential future developments, and the challenges associated with the
solubility and bioavailability of tailored nanocrystals, as discussed in this article. Consequently, it
possesses the capacity to provide guidance for future investigations pertaining to nanocrystal technology.

Authors: Aguiar Vicente , Almeida de Oliveira Kelly , Pereira Maduro Rossini
Published: November 2023

A pesquisa foca a ideia de corpo-corporeidades negras, indígenas e de diferentes orientações sexuais e suas resistências-existências na trajetória de formação acadêmica. Analisa posicionamentos políticos e religiosos com relação à política de inclusão das diversidades no ensino escolar, ao mesmo tempo busca conhecer os entendimentos de docentes em formação na graduação sobre essa temática. A análise foi realizada à luz da filosofia da diferença, que considera as existências em suas formas de sentir, pensar, existir e ser no mundo que não se modulam, tampouco se enquadram em modelos existentes e hegemônicos. Treze respostas não demonstraram compreensões sobre corporeidades; doze, afirmaram que o racismo, o preconceito, a violência são determinações da sociedade e nove reconhecem e os entendem como criações que podem ser transformadas. Os dados indicam a necessidade de investimentos na formação docente de maneira que possam expandir suas compreensões sobre essas temáticas diretamente ligadas aos direitos de existir.
Masculinidades Suaves no K-Drama Hello, My Twenties!
Authors: Klein Carin , Robaski Justina Bechi
Published: November 2023

O artigo insere-se na perspectiva teórica dos Estudos Culturais e de Gênero e analisa o modo pelo qual o k-drama Hello, My Twenties! veicula representações de masculinidades juvenis. A metodologia associa-se à etnografia de tela, visibilizando e problematizando imagens, observando, assim, manifestações de masculinidades a partir de produtos culturais da Coreia do Sul. Atentamos para os comportamentos, as características e os sentimentos que os jovens devem incorporar enquanto sujeitos de gênero, possibilitando-nos não apenas pluralizar as compreensões da juventude contemporânea, mas ampliar o entendimento de que as instituições e os diferentes locais da cultura veiculam pedagogias. Pela análise, a masculinidade “suave” apresenta sentidos ligados ao feminino, mas que não contestam a vivência da heterossexualidade. Entendemos que o artefato possibilita pensar em modos possíveis e plurais de ser homem e viver a masculinidade, ligados à diversidade de interesses de uma sociedade.

Authors: De la Torre-Diaz Lorena , Rodríguez-Aguilar Roman , Rivas-Aceves Salvador
Published: November 2023

This paper seeks determines how the possession of health and social protection assets affects the probability of a household belonging to a given quintile of a proposed asset ownership index. An ordered logistic regression model was constructed. As a dependent variable, the quintile of each household was used according to the index. This research is based on 48 explanatory variables from the 2020 National Income and Expenses Survey. It confirms that health and social protection assets are relevant in the location of households in a quintile according to its socioeconomic condition. Estimated marginal effects and predictions for every quintile, show that the effect of the assets varies according to the quintile. Ownership of specific assets increase the likelihood of belonging to the higher quintiles. The possession of a voluntary pension fund is the most relevant asset. The empirical results obtained may contribute to design more efficient inequality-reducing public policies by promoting its acquisition and thereby encouraging social mobility. Main limitations of this research are related with the small number of health and social-protection related variables in the survey.

BACKGROUND

Establishing cost-effective informal care services for lonely elderly individuals living at home in developing countries could be an innovative approach to improving their well-being.

OBJECTIVE

This study aimed to investigate the effectiveness of an informal home care support intervention program (HoSIP) on loneliness and quality of life in community-dwelling lonely older adults.

METHODS

This quasi-experimental pre-post study employed a non-randomized control group design, with a 12-week intervention period and three follow-up points at the end of HoSIP. We used questionnaires to measure feelings of loneliness (UCLA-20), quality of life (CASP-19), general health (GHQ12), social network (LSNS-6), social support (MSPSS-12), and self-care ability (SASE-17). Repeated measures ANOVA was used to gauge the effect of the intervention program over time and in comparison with the control group. Data analyses were performed using IBM SPSS Statistics software.

RESULTS

We found a significant relationship among outcome variables, including feelings of loneliness (P< 0.001) and quality of life (P< 0.001) at different stages of measurements. Despite positive feasibility results, the implementation of HoSIP faced challenges due to a lack of facilities and the absence of supporting organizations.

CONCLUSIONS

Utilizing the existing capabilities of older adults to provide online and face-to-face care services to each other could be a cost-effective way to improve their quality of life and reduce loneliness. The facilitating process of such informal care services for lonely older adults should be managed by either governmental or non-governmental organizations to diminish the rate of social isolation among this vulnerable population group.

Hidden Dropout, Actual Dropout, and Preserving Tradition and Language among Israeli Youth of Ethiopian Origin
Authors: Mangasto Wovite Worko
Published: November 2023

Dropping out from school is a serious problem affecting education systems. This study aims to examine the importance of preserving Ethiopian culture among Israeli high school students of Ethiopian origin and the relationship between preserving this culture and perseverance in formal schooling. Keeping ethnic tradition was examined using two indices: keeping the language and preserving tradition. Although hidden dropout is very common, the related literature is insufficient. Moreover, there are hardly any studies examining dropout among immigrant students in general, and among Israeli immigrants of Ethiopian origin in particular. This study is a pioneering investigation, in both the phenomenon being studied and the target population—the relationship between preserving culture of origin and hidden dropout and actual dropout among adolescent immigrants and children of immigrants of Ethiopian origin in Israel. The current study follows qualitative interviews with members of three research groups: learners, hidden dropouts, and disengaged. The analysis revealed a relationship between the importance assigned to preserving tradition and hidden dropout. In the measures of assigned importance to preserving tradition and language of origin, both hidden dropouts and learners assigned high importance to these variables, as opposed to the disengaged group that assigned less importance to preserving ethnic tradition.
Analysis of Marginal Discourse: Identity Construction in Campus Wall Graffiti
Authors: Chen Hong
Published: November 2023

Campus wall graffiti plays a significant role in the identity construction of graffiti artists as a form of marginal discourse. However, due to its long-standing perception as a destructive activity and the unique cultural environment, graffiti research in China has been relatively underdeveloped, with a focus on theoretical investigations. This study collected a total of 391 textual and pictorial graffiti samples from a language university in China as the corpus. From the perspective of identity construction, this study analyzed the characteristics of campus wall graffiti, as well as the methods and content of identity construction. The findings revealed that campus graffiti exhibits characteristics such as informality, anonymity, and counter-culturality. The language behaviors and symbol usage in graffiti include both one-way output and two-way interaction, the employment of textual and pictorial symbols, and the use of metaphors and symbolism. The construction of identity in graffiti primarily involves cultural identity, social identity, and creative identity among others. Lastly, in terms of campus graffiti management, this paper proposes effective strategies from the aspects of discourse power allocation and management, as well as feedback and reconstruction of identity construction. These strategies aim to transform disorder into order and foster an open and inclusive campus culture.

Authors: MOHANTY SATYABRATA , GUPTA JITENDRA KUMAR
Published: November 2023

Objective: Traumatic injuries involving the upper limbs present complex challenges, necessitating effective soft tissue coverage for optimal outcomes. This manuscript explores soft tissue reconstruction techniques for upper limb trauma, focusing on insights from a study conducted in Jaipur, India. The study evaluates the use of locoregional pedicled flaps and abdominal pedicled flaps in this specific context.

Methods: A study involving 50 patients was conducted to assess outcomes of locoregional and abdominal pedicled flaps for upper limb soft tissue defects. Patient profiles, surgical procedures, and outcomes were analyzed. Locoregionalpedicled flaps included the Posterior Interosseous Artery Flap (PIAF) and the Reverse Radial Forearm Flap (RRFF), while abdominal pedicled flaps employed the Superficial Circumflex Iliac Artery (SCIA) flap and Superficial External Pudendal Artery (SEPA) flap.

Results: Locoregionalpedicled flaps exhibited favorable outcomes, with efficient defect coverage and rapid mobilization, leading to improved joint mobility and function. Abdominal pedicled flaps achieved coverage but with longer immobilization periods and limited joint mobility. Comparative analysis indicated superior results with locoregional flaps in terms of functional restoration, patient satisfaction, and early mobilization.

Conclusion: This study highlights the efficacy of locoregional pedicled flaps for upper limb soft tissue reconstruction in Jaipur. The advantages of rapid mobilization and improved functional outcomes make locoregional flaps preferable. Abdominal pedicled flaps offer coverage but are associated with challenges in joint mobility due to prolonged immobilization. Tailoring flap techniques to patient and regional factors optimizes outcomes in upper limb soft tissue reconstruction.

Perspectivas únicas: el espectro autista en mujeres
Authors: Pérez Estrada Katy Arlette
Published: November 2023

El trastorno del espectro autista, caracterizado por alteraciones en la comunicación social y comportamientos restringidos, presenta una prevalencia que destaca una relación de 1 mujer por cada 3 hombres, señalando una subrepresentación femenina. Las mujeres manifiestan las características del autismo de manera única, lo que plantea desafíos en la identificación y diagnóstico. Se observan dos perfiles: el externalizante, con interacción aparentemente sociable pero deficiente, y el internalizante, marcado por la timidez y la concentración en actividades como la lectura y la pintura. Durante las etapas preescolar y escolar, las niñas exhiben un juego simbólico más desarrollado y mayores intereses sociales en comparación con los niños en condiciones similares. En la adolescencia, surgen desafíos como el perfeccionismo, el acoso escolar y conductas autolesivas leves. Muchas mujeres están recibiendo diagnóstico tardío, por ejemplo, Ladyhawke, Susan Boyle y la psicóloga mexicana Yeimy Molina. Los instrumentos diagnósticos para el autismo no son sensibles al género. Es de suma importancia realizar investigación, instrumentos e intervenciones clínicas con perspectiva de género.

Authors: Silva Tatiane Regina da , Dell'Aglio Daniela Dalbosco
Published: November 2023

Sexual violence against children and adolescents can happen in any environment, whether at their own home, community, school or even online. In addition, sexual abuse is a complex concept since children and adolescents do not have the maturational and psychobiological conditions to face this violence. Therefore, this article aims to analyze scientific research on sexual abuse among children and adolescents by conducting a bibliographic review of national research to draw a theoretical framework of scientific reports published in the Scielo database (Scientific Electronic Library Online). Furthermore, an examination of nineteen publications on the matter (from 2004 to 2022) and a similitude analysis of the abstracts from the articles using the IRaMuTeQ program were performed and completed. The results of this research demonstrate that, in a historical context, sexual abuse against children and adolescents is a situation that needs attention due to its increased levels of violence. The research analyzed brings data that allows a reflection on the role of society and protection services in the intervention and decrease of sexual violence against children and adolescents since it is urgent and necessary to establish prevention strategies and support this public.
Zonas de Reserva Campesina e implementación del Acuerdo de Paz en Colombia
Authors: Barreto García Julián Camilo
Published: November 2023

El proceso de política pública y las configuraciones de agendas son de gran importancia para analizar la existencia y cambio de una política. El enfoque de corrientes múltiples permite controvertir la agenda del proceso de paz, en cuanto se incorporó transitoriamente el Acuerdo de Paz a la Constitución Política de Colombia, incluyendo en su primer punto la Reforma Rural Integral (RRI), indicando el reconocimiento y apoyo a la figura de Zonas de Reserva Campesina (ZRC).
La Ley 160 de 1994 adoptó esta figura como una política pública de desarrollo rural y campesino, fundamentalmente, a través del instrumento de titulación de territorios baldíos de la nación; sin embargo, las coaliciones promotoras de la implementación de esta figura son débiles, lo cual ha configurado inequidad política frente a agendas más robustas de titulación de baldíos a apropiadores de gran capital, a través de la figura de las Zonas de Interés de Desarrollo Rural, Económico y Social (ZIDRES); no obstante, coyunturalmente el Gobierno Petro estima romper esta tendencia.

A Deep Learning Architecture for Blind Image Super-Resolution in Medical Image System

Published: November 2023

Currently, the majority of single image super-resolution algorithms
based on convolutional neural networks presume that image degradation is
always bicubic down sampling. In practice, however, the mechanism of
medical image degradation is considerably more complicated than the
Artificially simulated degradation. When the medical image degradation
differs from the presumption, this algorithm performs significantly
worse than anticipated. we use a degradation comparative learning to
solve such problems. In addition, many CNN-based methods currently treat
various channels equally, despite the fact that their information
content is not equal, resulting in the underutilization of a great deal
of information. As a result, the reconstructed SR pictures’ texture
features are not sufficiently rich. In order to solve these issues, this
paper suggests a blind image super-resolution approach based on edge
reconstruction and an image feature supplement module. This method
reconstructs high-resolution images with rich texture information from
low-resolution images and accomplishes excellent performance in the
stable restoration of various degraded SR images. By comparing our
approach to other blind SR approaches using natural picture testing
datasets and medical images, we were able to show that it outperformed
them. The results of the experiments demonstrate that our method is
superior to the most cutting-edge ones currently in use.

Distributed hydrological water quality models are increasingly being
used to manage natural resources at the catchment scale but there are no
calibration guidelines for selecting the most useful gauging stations.
In this study, we investigated the influence of calibration schemes on
the spatiotemporal performance of a fully distributed process-based
hydrological water quality model (mHM-Nitrate) for discharge and nitrate
simulations at Bode catchment in central Germany. We used a single- and
two multi-site calibration schemes where the two multi-site schemes
varied in number of gauging stations but each subcatchment represented
different dominant land uses of the catchment. To extract a set of
behavioral parameters for each calibration scheme, we chose a sequential
multi-criteria method with 300.000 iterations.

For discharge (Q), model performance was similar among the three schemes
(NSE varied from 0.88 to 0.92). However, for nitrate concentration, the
multi-site schemes performed better than the single site scheme. This
improvement may be attributed to that multi-site schemes incorporated a
broader range of data, including low Q and NO3- values, thus provided a
better representation of within-catchment diversity. Conversely, adding
more gauging stations in the multi-site approaches did not lead to
further improvements in catchment representation but showed wider 95%
uncertainty boundaries. Thus, adding observations that contained similar
information on catchment characteristics did not seem to improve model
performance and increased uncertainty. These results highlight the
importance of strategically selecting gauging stations that reflect the
full range of catchment heterogeneity rather than seeking to maximize
station number, to optimize parameter calibration.
Lagrangian Decomposition of the Meridional Heat Transport at 26.5oN

The Atlantic Meridional Overturning Circulation (AMOC) plays a critical
role in the global climate system through the redistribution of heat,
freshwater and carbon. At 26.5N, the meridional heat
transport has traditionally been partitioned geometrically into vertical
and horizontal circulation contributions; however, attributing these
components to the AMOC and Subtropical Gyre (STG) flow structures
remains widely debated. Using water parcel trajectories evaluated within
an eddy-rich ocean hindcast, we present the first Lagrangian
decomposition of the meridional heat transport at
26.5N. We find that water parcels recirculating
within the STG account for 37% (0.36 PW) of the total heat transport
across 26.5N, more than twice that of the classical
horizontal “gyre” component (15%). Rather than being distinct from
the overturning circulation, the heat transport associated with the STG
is due to the formation of subtropical mode waters via a shallow
downward spiral, which ultimately feeds the northward limb of the AMOC.
Determining the Relative Contributions of Runoff and Coastal Processes to Flood Exposure across the Carolinas during Hurricane Florence

Estimates of flood inundation from tropical cyclones (TCs) are needed to
better understand how exposure varies inland and at the coast. While
reduced-complexity flood inundation models have been previously shown to
efficiently simulate the drivers of TC flooding across large regions, a
lack of detailed validation studies of these models, which are being
applied globally, has led to uncertainty about the quality of the
predictions of inundation depth and extent and how this translates to
exposure. In this study, we complete a comprehensive validation of a
reduced-complexity hydrodynamic model (SFINCS) for simulating pluvial,
fluvial, and coastal flooding. We hindcast Hurricane Florence (2018)
flooding in North and South Carolina, USA using high-resolution
meteorologic data and coastal water level output from an ocean
recirculation model (ADCIRC). We compare modeled water levels to
traditional validation datasets (e.g., water level gages, high-water
marks) as well as property-level records of insured damage to draw
conclusions about the model’s performance. We demonstrate that SFINCS
can accurately simulate coastal and runoff drivers of TC flooding at
large scales with minimal computational requirements and limited
calibration. We use the validated model to attribute flood extent and
building exposure to the individual and compound flood drivers during
Hurricane Florence. The results highlight the critical role runoff
processes have in TC flood exposure and support the need for broader
implementation of models that are capable of realistically representing
the compound effects resulting from coastal and runoff processes.
Analysis of sulfate resistance of concrete with RCA after one year exposure to sulfate solutions

Published: November 2023

External sulfate attack is one of the durability problems associated with concrete. Despite a perception that concrete made with recycle concrete aggregate (RCA) is of inferior quality, research has shown that RCA has the potential to satisfy the mechanical and physical requirements for a range of applications. Limited works were performed on the durability aspects of the RCA. The objective of the research described in this paper was to evaluate resistance to sulfate attack of concrete with RCA in which two types of cement (CEM I and CEM III) and two water to cement ratios (0.38 and 0.55) were combined. For the evaluation of sulfate resistance of these concretes, immersed in sodium and potassium sulfate solutions, a drop of compressive strength, length change, capillary water absorption and thermal analysis (TGA-DTA) were used. Satisfactory sulfate resistance of concrete with RCA can be achieved by applying CEM III and reducing water to cement ratios.

Published: November 2023

In the course of the last few years, interest in the development of smart cities and progress of smart buildings has increased significantly. This development has been significantly increased due to the development of new technologies, innovative functional materials, electronic components and other products. At the same time, it is imperative to use those products that contribute to the preservation of the environment, and above all to energy saving. Thus, new technologies are becoming increasingly attractive, such as the one based on OLED (Organic Light Emitting Diode) technology, which is used in the production of mobile phones, tablet computers, other devices, as well as light sources. Although this technology has been generally known for more than half a century, commercial application of OLED components was not possible due to insufficient efficiency of products based on it. However, the continuous improvement of characteristics and efficiency enabled their more significant application in the past few years. The aim of this work is to provide adequate information about the possibilities of applying some innovative technologies in the planning and development of smart cities. Especially, becoming more familiar with the basic properties and application possibilities of OLED devices can lead to the life quality improvements of city spaces users.
