An SKP-ABE Scheme for Secure and Efficient Data Sharing in Cloud Environments
Authors: Hwang Yong-Woon , Kim Su-Hyun , Seo Daehee , Lee Im-Yeong
Published: June 2022

Security threats such as data forgery and leakage may occur when sharing data in cloud environments. Therefore, it is important to encrypt your data and securely access it when sharing it with other users via a cloud server. Of the various security technologies, research on secure data sharing commonly employs Key Policy Attribute-Based Encryption (KP-ABE). However, existing KP-ABE schemes generally lack ciphertext search features. Furthermore, even if a KP-ABE scheme incorporates it, the number of searches required increases markedly by the number of attributes used in the search. It in turn proportionally increases the ciphertext size. In addition, the attribute authority (AA) could be attacked, which can result in the leakage of users’ decryption keys. AA is a server that manages user attributes and decryption keys when using attribute-based encryption in a cloud environment. If the AA is curious, it can cause problems with the key escrow with the attributes and decryption (secret) key information of the users it knows. In this paper, to solve all these problems, we present a new scheme called Searchable Key-Policy Attribute-Based Encryption (SKP-ABE) for secure and efficient data sharing in the cloud. This proposed SKP-ABE scheme allows fast ciphertext search and keeps the ciphertext of constant size. The key escrow problem is solved via user key generation.

Published: June 2022

The usage of credit cards is increasing daily for online transactions to buy and sell goods, and this has also increased the frequency of online credit card fraud. Credit card fraud has become a serious issue for financial institutions over the last decades. Recent research has developed a machine learning (ML)-based credit card fraud transaction system, but due to the high dimensionality of the feature vector and the issue of class imbalance in any credit card dataset, there is a need to adopt optimization techniques. In this paper, a new methodology has been proposed for detecting credit card fraud (financial fraud) that is a hybridization of the firefly bio-inspired optimization algorithm and a support vector machine (called FFSVM), which comprises two sequential levels. In the first level, the firefly algorithm (FFA) and the CfsSubsetEval feature section method have been applied to optimize the subset of features, while in the second level, the support vector machine classifier has been used to build the training model for the detection of credit card fraud cases. Furthermore, a comparative study has been performed between the proposed approach and the existing techniques. The proposed approach has achieved an accuracy of 85.65% and successfully classified 591 transactions, which is far better than the existing techniques. The proposed approach has enhanced classification accuracy, reduced incorrect classification of credit card transactions, and reduced misclassification costs. The evaluation results show that the proposed FFSVM method outperforms other nonoptimization machine learning techniques.

Authors: Tian Mingjun , Zheng Minjuan
Published: June 2022

The heart is one of the most important organs of the human body. The role of the heart is to promote blood flow and provide sufficient blood flow to organs and tissues. The research on the heart has important theoretical and clinical significance. Because of the noninvasive and intuitive display of ultrasound image, it can dynamically obtain the heart state and has become the main means to detect the heart dynamics. We analyze the characteristics of cardiac ultrasound image from the medical point of view and signal processing. The heart movement is periodic and rhythmic. The image signal can be decomposed. Firstly, the image is decomposed into high‐ and low‐frequency signals to highlight different dimensional information. Then, the attention model was introduced, focusing on the heart region. Finally, the multidimensional network carrying model was established to achieve cardiac segmentation. The experimental results show that the AOM of the algorithm proposed in this paper reaches 92%, which has a certain degree of advancement and can assist doctors to make accurate diagnosis.
The Practical Application of Oil Painting in the Treatment of Mental Illness
Authors: Sun Xiaoming
Published: June 2022

With the rapid development of economy, politics, science, and technology and the improvement of living material level, people pay more attention to personal physical and mental development. The incidence of mental illness is on the rise. Psychological education curriculum learning and psychological counselling are based on communication; there are still many limitations. The art media enables patients to reveal their subconscious and potential emotional needs, so that interveners have the opportunity to explore these issues and build a bridge of communication with patients. In this paper, oil painting therapy of nonverbal communication is proposed as a way of psychological therapy. The patients in the psychological department of a hospital are served by six stages of therapy, each stage of treatment has different arrangements, and continuous service and treatment are adopted. Based on the art analysis principle of oil painting creation, the therapeutic experience obtained from oil painting creation and the experience gained from oil painting were divided into groups to compare the therapeutic effect and explore the role of oil painting art therapy. The results showed that the scores of the treatment group were significantly lower than those of the control group at 4 weeks and 6 weeks after the art therapy of oil painting creation, showing a significant downward trend overall. Oil painting art therapy may alleviate anxiety, providing data support for the application of oil painting art therapy in patients with depressive episodes.

Authors: Wu Liang
Published: June 2022

The multidepot capacitated arc routing problem (CARP) is investigated with the hybrid optimization algorithm of the Dijkstra algorithm and genetic algorithm. The complex multidepot CARP is transformed into multiple single depot CARP by systematic clustering analysis. After completing the system clustering, the Dijkstra algorithm is used to adjust the boundary arc locally and merge it to a reasonable depot, while in the genetic algorithm, the structure of the chromosome is reset to use the path as the way of real coding, and the elite selection is used to decode to obtain the optimal path optimization scheme. Finally, Lanzhou road network data as experimental data, through Matlab to achieve the practicability of the algorithm in sprinkler applications. The results show that the improved genetic algorithm can successfully solve the multi-segment CARP with a certain road network scale, ensuring the correctness and feasibility of the algorithm. In addition, the efficiency of the algorithm in the later iteration is basically controlled at about 0.5 seconds, indicating that the efficiency of the algorithm is worth identifying.

Published: June 2022

We report a case of a 54-year-old female patient who underwent PAC-IOL implantation 18 years prior to presentation. The patient had a best corrected visual acuity (BCVA) 20/20 in the right eye (OD) postoperatively with normal eye exam on routine follow-up since then. The patient presented for acute onset decreased visual acuity in the right eye. BCVA was 20/60, and exam showed blunted macular reflex with no evidence of inflammation. Optical coherence tomography (OCT) showed CME. She was started on topical treatment (ketorolac 0.5%) OD four times daily. Three weeks later, the patient had a BCVA of 20/20 OD with a normal macular reflex and an OCT showing the resolution of the CME. To our knowledge, this is the first reported case of a CME 18 years post PAC-IOL implantation. The possible cause of this incidence could be related to subclinical intraocular inflammation. Ophthalmologists should be aware of the possibility of such a latent CME post-PAC-IOL implantation.

Authors: Wang Jun , Mo Yimin
Published: June 2022

In order to realize the online monitoring of automotive engine lubricating oil, a method based on Internet of Things technology is proposed. This method uses the self-organizing neural network of the Internet of Things to fuse the original multidimensional feature data to obtain the fusion value. The Parzen window method is used to formulate the limit value of fusion value, and the samples are divided into three states: normal, warning, and abnormal. Weka software is used to extract rules from oil data. This method can identify different wear state information from oil spectral data, extract knowledge rules, and use them to build the knowledge base of automobile engine wear diagnosis system, so as to realize the automation and intelligence of automobile engine fault diagnosis based on lubricating oil spectral wear data. The measurement method of the lubricating oil sensor is mainly to comprehensively reflect the relationship between oil quality and electrical signal, so as to effectively provide users with reliable information. After many studies, it is concluded that the conductivity of lubricating oil has a good linear relationship with its acid value, metal particles, moisture content, and the change of additive content. Measuring the change of conductivity is an effective means to detect the change of lubricating oil quality. The experimental results show that using the extracted knowledge rules to verify the state of samples, the recognition rate is 97.47%. In order to more fully explain the difference between important element fusion and all feature fusion, all features are extracted. At the same time, the fault diagnosis and recognition rate of all features is not high, only 62.39%. It is proved that the Internet of Things technology can effectively realize online monitoring of the automotive engine lubricating oil.

Published: June 2022

Background. Thrombospondin type 1 domain-containing 7A (THSD7A) was reported to play a procancer role in esophageal squamous cell carcinoma (ESCC). The aim of the study was to screen the downstream functional genes of THSD7A and explore their functions in ESCC, based on the reported research into THSD7A function and on gene microarrays. Methods. We adopted quantitative reverse-transcription polymerase chain reaction (qRT-PCR) and Celigo high-content screening (HCS) technology to screen the downstream genes of THSD7A. The expression level of target genes was examined by PCR, western blot, and immunohistochemistry (IHC). The effects of these target genes on ESCC malignant biological behavior were performed in vivo and in vitro. The Kaplan-Meier (K-M) survival analysis and Cox regression were used to analyze the prognostic significance of target genes in ESCC patients. Experiments in the literature on liver cancer (LC) were repeated to verify the functions of these genes in different tumors. We further explored the cancer-promoting mechanism of target genes in ESCC by sequencing of the genes’ exons. Results. Scavenger receptor class A member 5 (SCARA5) was proved to be the downstream driving gene of THSD7A. SCARA5 promoted cell proliferation and migration but inhibited apoptosis in ESCC. IHC results confirmed that SCARA5 expression in ESCC exceeded that in normal tissues. The K-M survival analysis indicated that SCARA5 expression quantity was not related to prognosis, but tumor volume and T classification were both the independent prognostic factors. Repetition of experiments in LC in the literature confirmed that SCARA5 had exactly opposite functions in EC and LC. Conclusion. SCARA5 was related to the development and occurrence of ESCC. Our findings suggested that it was a potentially diagnostic individualized therapeutic target for ESCC in the future and that its application could possibly be combined with that of upstream THSD7A gene.

Authors: Li Bingyang , Quan Haiying
Published: June 2022

The application of motion capture system in basketball game can intercept the highlights of the game and improve the viewing effect. In order to improve the tracking performance of target tracking algorithm and the efficiency of traditional basketball tracking system, a correlation filtering algorithm combining multiple color features is adopted in this study. A dhcf as algorithm based on multicolor feature is established. The adaptability of traditional KCF algorithm in scene attributes such as rapid target change and illumination change is mainly studied. The success rate of multicolor tracking algorithm can reach 78.2%. At the same time, based on the traditional kernel correlation filter, the algorithm combines the discriminant color descriptor and the direction gradient histogram. The results show that the success rate and accuracy of the algorithm in otb50 are 84.2% and 82.5%, respectively. In addition, excellent tracking performance is reflected in various scene attributes. Therefore, the algorithm can improve the target tracking performance of the traditional kernel correlation filter, especially solving the adaptability of the traditional algorithm in the scene of light change, fast target movement, and so on.
Distributed Fixed-Time Coordinated Attitude Tracking Control with a Dynamic Leader for Spacecraft Formation Flying System
Authors: Zhou Zhanjie
Published: June 2022

This paper studies the problem of distributed coordinated attitude tracking control with a dynamic leader for spacecraft formation systems in the presence of parameter uncertainties and external disturbances. Under the constraint that the time-varying attitude trajectory of the leader is only available for a subset of the followers, a fixed-time distributed estimator for each follower is proposed. Moreover, a fixed-time distributed attitude tracking control law combined with a fixed-time distributed estimator and distributed adaptive control algorithm is proposed. This control law is dedicated to reducing the effects of system uncertainty and external bounded disturbances, and the settling time of this algorithm is independent of the initial state of the system. The fixed-time stability of the spacecraft formation system is proven with the Lyapunov-based approach, and numerical simulations clearly verify the effectiveness of the proposed control algorithm.

Published: June 2022

Nowadays, various algorithms are widely used in the field of economy and trade, and economic and trade management laws also need to introduce scientific and effective data models for optimization. In this paper, support vector machine algorithm and logistic regression algorithm are used to analyze and process the actual economic and trade case data and bank loan user data, and a hybrid model of support vector machine and logistic regression is established. This study first introduces the basic definitions and contents of the support vector machine algorithm and logistic regression algorithm, and then constructs a hybrid model by randomly dividing the data, first using the support vector machine algorithm to calculate the results, and then inputting them into the logistic regression algorithm. The first mock exam is that the efficiency of the hybrid model is much higher than that of the single model. This study mainly optimizes and upgrades the legal system of economic and trade management from two aspects. In the prediction of economic and trade legal cases, the hybrid model is significantly better than FastText and LSTM models in accuracy and macro recall performance. In terms of credit risk prediction of economic and trade loan users, the subset most likely to default in the loan customer set is obtained.

In the era of the Internet, artificial intelligence (AI) and other emerging technologies leading the industrial revolution, on the basis of comprehensive analysis of modern medical information services and analysis of the content of some hospital websites, from the perspective of the public, the expert scoring method is applied to establish medical information on hospital websites. Service comprehensive evaluation index system, at the same time quantification and assignment of indicators, combined with the theoretical research platform of information service quality. The comprehensive evaluation model of the medical information service function and quality of the hospital website was constructed by the comprehensive scoring method, and an empirical study was carried out. After comparing the data results of the model simulation with the actual data, it can be seen that the deviation between the actual data and the simulated data is not significant, that is, between 0.12% and 15.93%, which is within a reasonable range. Therefore, we have reason to believe that the model is an effective and reasonable use of the system dynamics method. On the basis of previous theoretical research and historical yearbook data, plus innovative theoretical assumptions, the Internet+healthcare embedded in the Internet+healthcare is constructed. The model of the traditional medical information service system can help clarify the role of Internet+health and medical information service in the overall medical information service system.

Authors: Mahmoudi Ali , Moallem Seyed Adel , Johnston Thomas P. , Sahebkar Amirhossein
Published: June 2022

Nonalcoholic fatty liver disease (NAFLD) is initiated by excessive fat buildup in the liver, affecting around 35% of the world population. Various circumstances contribute to the initiation and progression of NAFLD, and it encompasses a wide range of disorders, from simple steatosis to nonalcoholic steatohepatitis (NASH), cirrhosis, and liver cancer. Although several treatments have been proposed, there is no definitive cure for NAFLD. In recent decades, several medications related to other metabolic disorders have been evaluated in preclinical studies and in clinical trials due to the correlation of NAFLD with other metabolic diseases. Fenofibrate is a fibrate drug approved for dyslipidemia that could be used for modulation of hepatic fat accumulation, targeting peroxisome proliferator-activator receptors, and de novo lipogenesis. This drug offers potential therapeutic efficacy for NAFLD due to its capacity to decrease the accumulation of hepatic lipids, as well as its antioxidant, anti-inflammatory, and antifibrotic properties. To better elucidate the pathophysiological processes underlying NAFLD, as well as to test therapeutic agents/interventions, experimental animal models have been extensively used. In this article, we first reviewed experimental animal models that have been used to evaluate the protective effects of fenofibrate on NAFLD/NASH. Next, we investigated the impact of fenofibrate on the hepatic microcirculation in NAFLD and then summarized the beneficial effects of fenofibrate, as compared to other drugs, for the treatment of NAFLD. Lastly, we discuss possible adverse side effects of fenofibrate on the liver.
Colliding Epidemics: Research Gaps and Implementation Science Opportunities for Tobacco Use and HIV/AIDS in Low- and Middle-Income Countries
Authors: Parascandola Mark , Neta Gila , Bloch Michele , Gopal Satish , Ward Kenneth
Published: June 2022

Introduction. Tobacco use is a leading cause of cancer death among people living with HIV (PLWH) worldwide, and smoking prevalence tends to be higher among PLWH. The burden of both HIV/AIDS and tobacco use is increasingly concentrated in low- and middle-income countries (LMICs), where resources to address these challenges are often limited. However, there has been limited effort to date to integrate tobacco cessation into HIV programs in LMICs. Methods. We searched the literature (searching was conducted between October 1 and December 31, 2020) using PubMed including search terms “tobacco” and “HIV” and “cessation” over the past ten years (searching for articles published between December 1, 2010, and December 1, 2020) to identify original research studies on tobacco cessation interventions conducted in LMICs for PLWH. We also conducted an analysis of NCI-funded research grants on tobacco cessation and HIV awarded during fiscal years 2010 to 2020. Results and Discussion. Existing evidence suggests that conventional tobacco cessation treatments may be less effective among PLWH. Moreover, while substantial evidence exists to support a range of cessation interventions, most of this evidence comes from HICs and is only partly applicable to the evolving social, economic, and cultural climate of many LMICs. There is an urgent need to develop, adapt, and implement effective tobacco control and cessation interventions targeted to PLWH in LMICs, as well as to generate evidence from these settings. Implementation science provides tools develop and test strategies to overcome barriers and to integrate and scale up cessation services within existing HIV treatment settings. Conclusion. There is a unique opportunity to address HIV and tobacco use in a coordinated way in LMICs by integrating evidence-based tobacco cessation into HIV programs.

Published: June 2022

In a dynamic shift, lowering reliance on fossil fuels and greenhouse gas emissions is now a top goal. This is accomplished through expanding the usage of renewable energy. Solar photovoltaic (PV) energy is now more than ever at the heart of many cities’ policies. Improving the efficiency of PV systems is a current research goal. The key challenge in rectifying complex systems is to establish a model that correctly reproduces the system’s dynamic behaviour. The goal function and optimization method utilised are indicative of the model parameters’ correctness. This paper presents a mix of differential evolution (DE) and Harris hawk optimisation (HHO). The suggested technique estimates the parameter vector that minimises the objective function to the greatest extent possible. This is for the many diode models. The procedure is validated using experimental data acquired at a known temperature and irradiance. The root mean square error (RMSE) is used to assess the method’s effectiveness. A comparison is made between the objective function of the hybrid approach presented in this publication and previously authorised methods. The strategy utilised is as straightforward as many others stated in our predecessors’ publications, and this applies to both models analysed. When compared to the simple version of the Harris hawk optimizer, this approach allows for more experimentation.

Published: June 2022

Functional rehabilitation programs in multiple sclerosis have demonstrated their efficacy in improving fatigue. The assessment of functional impairment, however, is more difficult. The purpose is to assess fatigue and disability as a first study measure and to verify their improvement after a specific functional rehabilitation program. An analytical, longitudinal, prospective, and experimental study was carried out with 51 patients aged 18-55 years, with an Expanded Disability Status Scale (EDSS) between 2 and 6.5 who were being followed up in outpatient clinics of the Rehabilitation Service of La Princesa Hospital. The fatigue and disability outcomes before and after a structured exercise training program were evaluated, with each subject acting as their own control. The variables were measured using the Modified Fatigue Impact Scale (MFIS), Barthel Index (BI), and Functional Independence Scale (FIM). Differences according to recurrent or progressive course of the disease are assessed. Improvement in the FIM scale was observed after the retraining program (

p
=
0.016

) and was maintained in the medium term (

p
=
0.042

). This improvement is not statistically significant in Barthel Index. Improvement in MFIS is observed after the program (

p
<
0.001

) and 4-6 months after the end. Both disease courses experience the same improvements with no statistically significant differences between them. The retraining program improves fatigue and multiple sclerosis-related functionality in the short and medium term. There are no differences according to disease course. Both experience the same positive changes with our intervention.

Authors: Shi Lingli , Liu Lu , He Yong , Yang Yuling , Ni Huanhuan
Published: June 2022

Background. Sufentanil is widely used during anesthesia induction. However, it can cause coughing via different mechanisms. This study is aimed at evaluating the effectiveness of a small dose of oxycodone and sufentanil in suppressing sufentanil-induced cough (SIC) during general anesthesia induction. Methods. Of the 174 patients scheduled for elective surgery, 144 were eligible and randomly divided into 3 groups (

n
=
48

). Five minutes before sufentanil bolus (0.4 μg/kg), patients in group O received 0.02  mg/kg oxycodone intravenously within 5 s, those in group S received 0.02 μg/kg sufentanil within 5 s, and those in group N received an equal volume of 0.9% normal saline within 5 s. Sufentanil was diluted to 5 μg/ml and administered within 5  s after pretreatment. The incidence and severity of cough in the three groups were evaluated within 1 minute after sufentanil injection during the anesthesia induction. Their mean arterial pressure (MAP) and heart rate (HR) were recorded at T0 (after entering the operation), T1 (3 minutes after pretreatment), T2 (before intubation), and T3 (1 minute after intubation). Results. The incidences of cough in group N, group O, and group S were 20 (41.6%), 7 (14.5%), and 6 (12.5%), respectively. Compared with group N, patients from group O and group S exhibited significantly reduced incidence and severity of cough, and the severity of cough in group O and group S was significantly reduced compared with group N (

P
<
0.05

). No significant differences in the rangeability of MAP and HR were noted at the four time points in the three groups (

P
>
0.05

). Conclusion. Preconditioning using intravenous oxycodone (0.02 mg/kg) or sufentanil (0.02 μg/kg) could represent an effective approach to reducing SIC in anesthesia induction and was associated with relatively stable hemodynamic state during general anesthesia. This trial is registered at Chinese Clinical Trial Registry with registration number ChiCTR1900021087.
On the Voltage Response of Homogeneous Earth Models in Central Loop Electromagnetic Sounding
Authors: Parise Mauro
Published: June 2022

An accurate series-form explicit expression is derived for the voltage induced in the small receiving loop of a central loop electromagnetic sounding system positioned above a homogeneous earth model. The solution is obtained by converting the semi-infinite integral representation for the vertical magnetic field induced at the center of the two loops into a series of simpler integrals, amenable to analytical evaluation. The developed formulation is based on replacing the exponential term in the integrand of the field integral with its power series expansion with respect to the difference of the squares of the wavenumbers in air and in the conducting medium. As a result, the vertical magnetic field and the induced voltage are finally expressed as sums of the spherical Hankel functions depending on geometrical parameters and the wavenumbers. The derived solution exhibits advantages in terms of both time cost and accuracy, when compared to the conventional numerical schemes for evaluating the Sommerfeld-type integrals and to the previously published quasistatic solution to the considered problem.

Traumatic brain injury (TBI) is still a major cause of concern for public health, and out of all the trauma-related injuries, it makes the highest contribution to death and disability worldwide. Patients of TBI continue to suffer from brain injury through an intricate flow of primary and secondary injury events. However, when treatment is provided in a timely manner, there is a significant window of opportunity to avoid a few of the serious effects. Pioglitazone (PG), which has a neuroprotective impact and can decrease inflammation after TBI, activates peroxisome proliferator-activated receptor-gamma (PPARγ). The objective of the study is to examine the existing literature to assess the neuroprotective and anti-inflammatory impact of PG in TBI. It also discusses the part played by microglia and cytokines in TBI. According to the findings of this study, PG has the ability to enhance neurobehavior, decrease brain edema and neuronal injury following TBI. To achieve the protective impact of PG the following was required: (1) stimulating PPARγ; (2) decreasing oxidative stress; (3) decreasing nuclear factor kappa B (NF-κB), interleukin 6 (IL-6), interleukin-1β (IL-1β), cyclooxygenase-2 (COX-2), and C-C motif chemokine ligand 20 (CCL20) expression; (4) limiting the increase in the number of activated microglia; and (5) reducing mitochondrial dysfunction. The findings indicate that when PIG is used clinically, it may serve as a neuroprotective anti-inflammatory approach in TBI.

Published: June 2022

More than a century separates the description of “dropsy of the ventricles of the brain” by Scottish physicians and Robert Koch’s identification of the causal agent of tuberculous meningitis in 1882. This article reviews the writings in Scotland and France that marked the history of the identification of this infectious entity. From John Paisley in 1734 to Robert Whytt in 1738, from Marcellin Chardel in 1799 and L.P. Collinet in 1802 to Isidore Bricheteau in 1814 and Jean-Louis Brachet in 1818, and then Victor Le Diberder in 1837 and Isidore Valleix in 1838, unknown and forgotten physicians outnumber the famous masters in bringing about the progress and knowledge that enabled this frequent and consistently fatal disease in the 19th century to be accurately diagnosed and in most cases cured in the 20th century.
New Targets for Extracorporeal Blood Purification Therapies in Sepsis
Authors: Monard Céline , Abraham Paul , Schneider Antoine , Rimmelé Thomas
Published: June 2022

As highlighted by the last international consensus definition for sepsis and septic shock (sepsis-3), sepsis comes from a complex relationship between a pathogen and a dysregulated host response. To date, the treatment of sepsis is based on antimicrobial treatment, source control, and organ support. Extracorporeal blood purification therapies have been proposed as adjuvant therapies to modulate the dysregulated inflammatory response. These therapies aim mostly at removing inflammatory mediators (cytokines) and endotoxins from the blood. However, so far, they failed to clearly demonstrate an improvement in patient survival when evaluated in randomized trials. Recently, new devices directly targeting the primary determinants of sepsis, e.g., the pathogen itself and the host immune cells, have been developed. This short review aimed at presenting new blood purification devices that have recently been developed to target pathogens and immune cells. For each, we will present the mechanism of action of the therapy and discuss the related literature.

Authors: Garduño Vieyra Leopoldo , Rúa Martínez Raúl , Flores Escobar Bruno
Published: June 2022

Fungal keratitis is a complication of refractive surgery that, if not treated in time, can lead to blindness. Given the lack of effective topical treatments for fungal ulcers, surgical treatment is necessary. The least invasive procedure is a cross-linking pack, although it has limitations when the fungus has penetrated the deep layers of the cornea. In this case report, a patient that presented a typical case of fungal corneal ulcer with hand motion perception, on the fourth day after surgery, is described. Given the nonresponse to topical antifungal treatment, plasma treatment was performed prior to cross-linking.

Background: Diabetic kidney disease is a major cause of global end-stage renal diseases. Ectopic lipid deposition in the renal tissues of diabetic kidney disease is one major factor leading to renal fibrosis and chronic kidney disease. Pterostilbene has been reported to display lipid-lowing activity and participate in many kidney diseases. However, the influence of pterostilbene on the ectopic lipid deposition is unclear. We intend to explore the influence of pterostilbene on the ectopic lipid deposition in the kidneys of mice induced by high fat. Methods: A high-fat diet-induced diabetic mouse model was established to detect the alleviative effect of pterostilbene on the ectopic lipid deposition in the kidneys of diabetic mice. A biochemical analysis was performed to examine the levels of urine albumin, urine creatinine, serum creatinine, and blood urea nitrogen in mice after pterostilbene treatment. Histological analysis was conducted to detect the degree of renal injury and fibrosis. Oil red O staining and immunohistochemical staining were carried out to evaluate lipid droplets and the expression of adipose differentiation-related protein in renal tissues of the mice treated by pterostilbene. The protein levels were assessed by Western blotting. Results: Pterostilbene inhibits the expression of the TGF-β1 and p-smad3 and suppresses the protein levels of SREBP-1 and FAS, and it ultimately reduces the ectopic lipid deposition, alleviates the renal tubular damage and renal fibrosis in the kidneys of diabetic mice induced by high fat, and improves kidney function. Conclusion: Pterostilbene alleviates renal fibrosis and ectopic lipid deposition in the kidneys of diabetic mice induced by high-fat diet by inhibiting the TGF-β1/smad3 signaling.
Uma arquetipologia da morte em Venha ver o pôr-do-sol, de Lygia Fagundes Telles
Authors: Pelinser André Tessaro
Published: June 2022

Este ensaio analisa o conto de Lygia Fagundes Telles intitulado “Venha ver o pôr-do-sol”, enfatizando a presença de elementos constituintes de uma arquetipologia da morte, à qual se vincula uma série de símbolos responsáveis por consolidar a atmosfera lúgubre da trama e conduzir o leitor sempre em tensão por seus meandros. Busca-se evidenciar de que maneira a autora utiliza-os para construir uma linha de ascensão e queda que percorre toda a narrativa, sinalizando que o movimento ascensional em nada divino culmina na engolição pelo abismo voraz.

El Blog de Ferréz: en búsqueda de la literatura
Authors: Tennina Lucía
Published: June 2022

El artículo consiste en un análisis de una discusión que se dio en el blogspot de Ferréz a partir de la publicación de un cuento llamado “Pensamentos de una correria”. Tiene como objetivo centrar la atención en los pactos de lectura que se generan respecto de los textos producidos en la periferia en relación con los diferentes contextos en los que se publican (el periódico, el blogspot, el libro). La reflexión se desplaza también hacia el concepto de ficción y de escritor que este tipo de escrituras construye en cada caso.
A potência do axé e suas relações entre imagem, transformações e visibilidade
Authors: Torres Díjna Andrade
Published: June 2022

Este artigo discute representações do Candomblé produzidas por quem faz parte dele, em três terreiros sergipanos, de linhagens distintas. O recorte imagético escolhido é a fotografia, uma vez que, apesar de as fotografias serem vistas como recortes de realidades e contextos, elas apresentam uma série de interpretações acerca daquilo que querem comunicar. Busco pensar nos atos performativos e políticos que esses sujeitos realizam ao tornar visíveis ou não as imagens que são produzidas nestas três casas. Potência foi pensada justamente pelo fato de a palavra Axé representar Força, e, portanto, me remeter à sua potencialidade enquanto mantenedora da religião. Em campo, ouvi muito as frases como “dá pra sentir o axé na foto”; “esse santo aí tem muito axé”, a uma força ritual, que apesar de estar fixada numa imagem, é sentida por aqueles que a reconhecem em seus cotidianos.

Feitios de Mateba: poesia angolana na composição de uma identidade nacional
Authors: Carvalho Maria do Socorro Fernandes
Published: June 2022

A composição de uma identidade nacional em Angola prossegue em compasso com a evolução das formas artísticas. A poesia, especificamente, tem sido um instrumental na construção de uma literatura identificada com a cultura angolana. Tendo início com a voga jornalística da segunda metade do século XIX, com o romance nos anos trinta deste século e amadurecendo com a poesia a partir dos anos 50, o conjunto da literatura angolana tem por base dois pilares entre si conflitantes e, ao mesmo tempo, complementares: a tradição da cultura oral e a herança literária da língua portuguesa. Alguns textos dos poetas contemporâneos Arlindo Barbeitos e David Mestre, aqui analisados, apresentam essa antinomia, cuja síntese parece estar na imbricação dos elementos nativos com os herdados.

O problema da autonomia e da denominação da literatura angolana
Authors: Brandão Fernando A. Albuquerque
Published: June 2022

Uma incursão no histórico da evolução do romance africano permite, até certo ponto, aclarar as ambigüidades surgidas ao longo do processo. O romance, a par das outras formas da ficção ou da poesia é, sem dúvida, um dos instrumentos para o conhecimento dessa fase do processo colonial. Uma das obras centrais da literatura angolana do começo do século dá-nos essa idéia. A divulgação da literatura africana fora do espaço nacional deve ser apresentada num quadro de autonomia, independentemente da língua utilizada.
Navegando contra a corrente: o papel dos escravos e da flora africana na botânica do período colonial
Authors: Carney Judith
Published: June 2022

O caráter revolucionário das trocas ecológicas e botânicas que sucederam a expansão marítima Européia pós 1492 é hoje largamente reconhecido. Não obstante, a literatura que estuda as trocas culturais e comerciais do período pós-Colombiano permanece omissa no que se refere à disseminação alhures de plantas nativas da África e aos meios pelos quais isto ocorreu. Para reverter esta corrente, como revela este artigo, torna-se necessário que se caracterize o papel que o comércio transatlântico de escravos teve na dispersão destas plantas, assim como a importância que os escravos africanos desempenharam na consolidação de gêneros alimentícios básicos da culinária das Américas. Ao dar destaque à diáspora africana, enquanto um fenômeno que envolve tanto pessoas quanto plantas, coloca-se ênfase nos sistemas primitivos de conhecimento africano. A expressão destes sistemas de conhecimento na coesão de comunidades inteiras de africanos reflete formas particulares de relações de poder, preferências alimentares, identidade cultural, e disputas sobre o processo de trabalho. Ao dar relevo às plantas africanas estabelecidas nas Américas, este artigo procura corrigir uma distorção comum em narrativas sobre as trocas transatlânticas: a insistência em enfatizar o papel dos europeus na disseminação de plantas a nível intercontinental e em valorizar produtos agrícolas de origem Ameríndia e Asiática em detrimento da contribuição africana. O objetivo deste trabalho é promover o resgate histórico do papel da África na botânica colonial.
