The ground states for the non-cooperative autonomous systems involving the fractional Laplacian
Authors: Li Suhong , Wu Limeng , He Shiqian , Zhang Lingmin
Published: February 2022

The aim of this paper is to study the the following non-cooperative autonomous systems involving the fractional Laplacian(−∆)su + λu = g(v), in RN,(−∆)sv + λv = f(u), in RN,where s ∈ (0, 1), N > 2s, λ > 0, (−∆)s is the fractional Laplacian and f and g are power-type nonlinearities having super-linear and subcritical growth at infinity. We establish the existence of the ground states of the system through variational methods. The variational frame associated to the system is strongly indefinite, which is different from the one of the single equation case and the one of a cooperative type. Furthermore, some properties of the solutions such as regularity, symmetry and decay are also discussed. Mathematics Subject Classifications (2020): 35Q40, 49J35, 34A08, 47J30.
X-Ray Fluorescence as a Method of Characterizing Inorganic Pigment Patterns in the Work of Julian Onderdonk.
Authors: Dostal Christopher
Published: February 2022

This study utilized portable X-Ray fluorescence to analyze pigment patterns in 33 paintings by Julian Onderdonk, a 19th-20th century Texas impressionist. This analysis led to the identification of distinctive pigment preferences for Onderdonk at different periods of his career. Using the pigment preference patterns identified in the paintings that were dated by the artist, undated works were analyzed and assigned to different periods in the artists career based on their pigment patterns. This study represents a non-destructive method for organizing the artist’s work without solely relying on stylistic changes.
Interfacial evolution and mechanical behavior of explosively welded titanium/steel joint under subsequent heat treatment process
Authors: Wu Tong , Yang Chunli
Published: February 2022

The TA2/15CrNi3MoV clad plates were fabricated by explosive welding and then were heat-treated in the temperature range of 700-1000 ℃ for 30 min. Its microstructure and tensile strength were investigated and the results elucidated that the heat treatment process accelerated the interdiffusion of constituent elements (e.g., Fe, Ti and C) at the TA2/15CrNi3MoV interface, thus resulting in the formation of FeTi, Fe2Ti and TiC. For the samples heat-treated at 700 ℃, a continuous TiC layer was generated at the TA2/15CrNi3MoV interface, which hampered the formation of FeTi and Fe2Ti. However, for the samples heat-treated at 800 ℃, the continuous TiC layer was broken up, resulting in a significant increase in the Fe-Ti layer to 1.21 μm. This resulted in a dramatic drop in tensile strength to 329.2 MPa. For samples heat-treated in the temperature range of 900-1000 ℃, the thickness of the brittle Fe-Ti layer was increased dramatically, leading to a rapid drop in tensile strength.

Published: February 2022

The objective: to analyze and compare frequency and variety of adverse events (AEs) and their impact on outcomes of tuberculosis therapy when treating patients with multiple drug resistant tuberculosis (MDR TB) and different HIV statuses.Subjects and Methods: retrospective observational case-control study of patients registered for treatment with the 4th regimen of chemotherapy for tuberculosis in the city of Vladimir and Vladimir Region in 2014-2016.Results. The proportion of patients who reported any AE during the MDR TB treatment was similar among HIV positive and HIV negative patients and made 85.5%. In patients with concurrent HIV infection and MDR TB, hematopoietic AEs such as anemia, thrombocytopenia were more frequent, while neutropenia was significantly more frequent when comparing groups by the cumulative event probability method. Elevated eosinophil level during treatment was more typical of MDR TB patients. Treatment outcomes in the group of patients with HIV and MDR TB were statistically significantly worse due to the higher frequency of fatal outcomes. At the same time, there was no correlation of AE with unfavorable treatment outcomes. The early initiation of combination therapy with thorough monitoring of hematologic parameters in patients with HIV and MDR TB was safe and effective.
Pharmaceutical Company In-house Research and Licensing Transaction Review
Authors: Drago Thomas , Cahill Katelynn , Grealy Alannah , Lucey Kieran , Mahmoud Muhammad
Published: February 2022

Background:​ Pharmaceutical in-house research and licensing deals are effective means of widespread production of drugs to the public. These transactions follow a normalized procedure requiring upfront payments between a buying company to work either collaboratively with a small to medium sized selling company or buying the right of a product completely. Licensing a novel pharmaceutical drug goes through several clinical phases, and transaction deals can involve royalty and/or milestone payments along the research and clinical trial process. Methods​: Data was collected through analysis of pharmaceutical licensing market deals via online databases and extracted to a data sheet for examination. Trends were highlighted after analyzing upfront payment values, royalty sales, milestone payments and total transaction deal value. Results​: Total milestone payments averaged at USD $639.1 million, and total royalty payments averaged at USD $899.77 million. Average total deal values is USD $1445.18 million. Correlation coefficients between: (1) upfront and milestone payments r = 0.155; (2) upfront payments and royalty payments r = 0.188; and (3) upfront payments and total deal value r = 0.604. Most transactions are a small/medium enterprise selling to big pharmaceutical companies (32%) or a big pharmaceutical company selling to a small/medium enterprise (32%). 27% of deals are between big pharmaceutical companies, and 9% of deals are between small/medium enterprises. Conclusion:​ There is a positive correlation between upfront payment costs with milestone/royalty costs and total deal value (n=25). Small or medium enterprises are beginning to take a large sector of the transaction business as their in-house research licensing grows more appealing for market distribution.

Authors: Jin Yap Ngee , Ng Nathan
Published: February 2022

Background
Glaucoma is one of the most common ophthalmic conditions encountered in primary and secondary care. Glaucoma has the potential to impair driving. This audit aims to investigate how well we are giving driving advice to Glaucoma patients in the setting of the United Kingdom (UK).
Methods
Two junior doctors interviewed all glaucoma patients who attended glaucoma clinic in 4-week period on whether they had received advice regarding driving. Patients who never drove and did not respond were excluded from the analysis
Results
Of the 110 patients, we found that only 29% of patients recalled receiving any driving advice from their ophthalmologist of optometrist. A significant number of patients (33%) wanted more information.
Conclusion
Driving advice is poorly delivered to patients with Glaucoma. Simple interventions can potentially increase delivery of advice to patients.
El sentido de vida, una condición existencial
Authors: Vanegas Rivas Paula Andrea , Marín Rodríguez Juan Sebastián
Published: February 2022

El ser humano siempre ha estado en la constante búsqueda de sentido y preguntándose por su existencia. El hombre moderno además de encontrase en esa búsqueda, también se halla permeado por la angustia constante, está sometido a la cosificación de sí mismo, la hiper-conectividad, el consumismo, la incertidumbre y la inmediatez, lo cual lo conduce de manera casi inminente al aburrimiento y el tedio, es decir, a la frustración existencial, llevándolo a enfrentarse con sus pseudo-satisfactores y dejándolo de cara ante el vacío de su propia existencia y el cuestionamiento: ¿para qué estoy en el mundo?
Positioning of low-urbanized territories based on self-identification: The case of Ukraine
Authors: Hlynskyy Nazar , Hirna Olha
Published: February 2022

In the context of competition for limited resources for the development of territorial communities in Ukraine, the use of marketing tools in managing local development is becoming increasingly important. One of these tools is positioning. In the case of territorial communities, it is a communicative expression of their identity. This study aims to determine the positioning characteristics of small territorial communities in Ukraine (low-urbanized territories – communities with a predominantly rural population) in formulating their positioning criteria. The subject of the analysis was the strategic visions formulated in the long-term planning documents of low-urbanized territories. Descriptive information was evaluated and grouped using expert methods. It was determined that low-urbanized territories in Ukraine use a multi-criteria approach in the positioning process: the number of applied criteria reached 26 (an average of 6 criteria). Each of them is focused on specific target audiences – residents, investors/local businesses, and tourists/visitors (48% for each of the target audiences). At the same time, less than half of the surveyed communities (44%) position themselves as “territories of developed agriculture”. Since little research has been done on the positioning of territorial communities in the Ukrainian context, this study has contributed new knowledge in this field.
A 2000-2015 közötti családpolitikai intézkedések hatása a születésszámra Magyarországon
Authors: Bördős Katalin , Szabó-Morvai Ágnes
Published: February 2022

Elemzésünkben a 2000 és 2015 közötti családpolitikai támogatások és intézkedések fertilitásra gyakorolt hatását vizsgáljuk, melyet FH panel regressziókat használunk. Eredményeink azt mutatják, hogy a családtámogatási rendszer azon elemei vannak a legnagyobb hatással a termékenységre, amelyek a foglalkoztatási, a megélhetési és a lakhatási lehetőségeket javítják. A nők jelenlegi foglalkoztatottsága, a bölcsőde és az óvoda elérhetősége és a részmunkaidős munkalehetőségek jelentősen növelik a tisztított élveszületési arányszámot, mely különösen igaz az első gyermek esetében. A családtámogatási rendszer egészét tekintve a hazai beavatkozások hasonló eredményességet mutatnak, mint a többi országban: enyhén pozitív, szignifikáns hatással vannak a termékenységre. A kapott eredmények arra utalnak, hogy a foglalkoztatás és a bérek növelését célzó gazdaságpolitikák valószínűleg a leghatékonyabb termékenységi politikák közé tartoznak. Ugyanakkor az eredmények azt is megmutatták, hogy a megfizethető lakhatás kulcsfontosságú tényező, amit nem csupán saját lakás vásárlását elősegítő támogatásokkal, hanem a bérlakáshoz jutást segítő programokkal is lehetne támogatni.
The Poetics of Fei Ming: How the Classical Merged with the Modernist
Authors:   Foreign Languages College, Shanghai Normal University, China, Wang Candy Fan
Published: February 2022

Fei Ming (1901-1969) is an iconic fictionist who had mastered the fusion of Chinese classical literary images with Western modernist writing techniques, a glaring label overshadowing his accomplishments in poetry. This paper looks at Fei Ming’s footprint in poetry within the context of the reforming and modernizing process of Chinese poetry in the first half of the 20th century. It offers a particular angle of viewing Fei Ming’s undervalued poetic aesthetics, in which he seamlessly reconciled the confrontational forces vacillating the development of Chinese poetry, namely, traditional form versus modern form and Chinese style versus Western style. Specifically, he blended modern philosophy with traditional lyricism to create natural flows of beauty and imbedded the Western symbolist and imagist techniques in forming a unique Chinese poetry style without compromising the sense of coherence. His proposal that new poetry should embrace a poetic “mind” with a prose-like “body” has shaped the making of Chinese modern poetry in its time of need. His equal treatment of the poetic elements of Chinese tradition and Western modern manifests a new interpretation of modernist poetry, a different mentality to approach modernism, and further a distinct paradigm of global modernisms, alternative to the Anglo-American ones.
Skinned Performance: Female Body Horror in Joko Anwar’s Impetigore
Authors:   Department of English, Ateneo de Manila University, Quezon City, Philippines, Sutandio Anton
Published: February 2022

This article discusses the 2019 Indonesian horror film, Impetigore (Perempuan Tanah Jahanam) directed by Joko Anwar. In 2021, Impetigore became the first Indonesian horror film to represent the country at the Academy Awards. This article focuses on the film’s mystification of the female body, which points towards gender relations. This research utilizes the concept of body horror, particularly relating to the skin, gender relations, and wayang mysticism. The findings show that the film metaphorically underlines the ongoing disconcerting perspective of contemporary Indonesian society on women’s embodied agency. The film’s portrayal of non-traditional female characters suggests an attempt to challenge the mainstream patriarchal narrative in contemporary Indonesian horror cinema, and at the same time hints at the perpetuating subjectification of woman’s bodies as a threatening yet desirable agency.

The current COVID-19 pandemic has emphasized the vulnerability of communities living in the urban outskirts and informal settlements. The lack of reliable COVID-19 case data highlights the importance and application of wastewater-based epidemiology. This study aimed to monitor the COVID-19 trends in four vulnerable urban communities (slums and low-income neighborhoods) in metropolitan São Paulo by assessing the SARS-CoV-2 RNA viral load in wastewater. We analyzed 160 samples from May 2020 to June 2021 with weekly or fortnightly samplings. The samples were ultracentrifuged with glycine elution and quantified by N1/N2 SARS-CoV-2 RT-qPCR. The results of positivity were 100% (Paraisópolis, Heliópolis and Cidade Tiradentes) and 76.9% (Vila Brasilândia). The new case numbers of COVID-19, counted from the onset of symptoms, positively correlated with SARS-CoV-2 N1 viral loads from the two largest communities (p<0.001). SARS-CoV-2 infectivity was tested in Vero E6 cells after concentration with the two techniques, ultrafiltration (Centricon® Plus-70 10 kDa) and sucrose cushion ultracentrifugation, but none of the evaluated samples presented positive results. Next-generation sequencing (NGS) analysis from samples collected in March and August 2021 revealed the presence of the clade 20 J (lineage P.1) belonging to the most prevalent circulating variant in the country. Our results showed that wastewater surveillance data can be used as complementary indicators to monitor the dynamics and temporal trends of COVID-19. The infectivity test results strengthened the evidence of low risk of infection associated with SARS-CoV-2 in wastewater.

Published: February 2022

Safety of improved water supplies using enterotoxins as a molecular marker is evaluated. Water samples were collected from 248 households and tested for enterotoxins using polymerase chain reaction (PCR). The relationships between the presence of at least one enterotoxin and independent variables were investigated using Chi-square (χ2), Fisher's exact test and binary logistic regression. Some 156 enterotoxin biomarkers were detected, 39% of samples had at least one, and 17% had multiple varieties. EAST1 was detected in the highest proportion of samples (33%) and Sta in the lowest (2%). Shallow groundwater sources yielded 18% less enterotoxins than water from piped systems, a statistically significant result (P=0.031). A lower proportion of enterotoxins was detected in relation to those who did not know and use cloth filters than those with knowledge of them, and the negative association is statistically significant (P=0.017). It was shown that water samples in which total coliform (TC) colonies were detected were more likely to contain enterotoxins than those without (P=0.001). It is concluded that enterotoxin molecular markers can be used to monitor water safety.
Targeting Ferroptosis Pathways: A Novel Strategy for Cancer Therapy
Authors: Maru Devangkumar , Hothi Akhil , Bagariya Chintan , Kumar Anmol
Published: February 2022

Ferroptosis is an iron-dependent nonapoptotic kind of regulated cell death resulting from
the destruction of redox balance in the cytosol. Unlike apoptosis, ferroptosis is caused by an increase
in intracellular iron and lipid peroxides that causes significant damage to the membrane lipid bilayer
and mitochondria leading to cell death. Increased iron level in the cell promotes ROS production.
Ferroptosis inducer molecules increase ROS production and inhibit the antioxidant defence mechanism
to facilitate ferroptosis in cancer cells. Inhibition of GPX4, redox-active iron availability, and
lipid peroxidation are major contributors to ferroptosis. Ferroptosis is involved in many diseases like
heart disease, neurodegenerative disease, and cancer. Ferroptosis induction recently emerged as an
attractive strategy for cancer therapy. In this review, we discuss the regulatory mechanism of ferroptosis,
its different hallmarks, including genetic and metabolic regulators and inducers that promote
ferroptosis in the cancer cells. Finally, the latest progress and development in ferroptosis research in
different cancers focusing on proposing a novel strategy in cancer therapy are discussed.
Changes in Histaminergic System in Neuropsychiatric Disorders and the
Potential Treatment Consequences
Authors: Shan Ling , Swaab Dick F.
Published: February 2022

In contrast to that of other monoamine neurotransmitters, the association of the histaminergic
system with neuropsychiatric disorders is not well documented. In the last two decades,
several clinical studies involved in the development of drugs targeting the histaminergic system
have been reported. These include the H3R-antagonist/inverse agonist, pitolisant, used for the treatment
of excessive sleepiness in narcolepsy, and the H1R antagonist, doxepin, used to alleviate symptoms
of insomnia. The current review summarizes reports from animal models, including genetic
and neuroimaging studies, as well as human brain samples and cerebrospinal fluid measurements
from clinical trials, on the possible role of the histaminergic system in neuropsychiatric disorders.
These studies will potentially pave the way for novel histamine-related therapeutic strategies.

Authors: Morris Humberto J. , Arias-Ramos Daily , Chil-Núñez Idelsy , Camacho-Pozo Miladis , Lebeque-Pérez Yamila , Llauradó-Maury Gabriel , Cos Paul , Vervaet Chris
Published: February 2022

Mushroom-based products can serve as superior nutraceuticals in both
preventing and alleviating human diseases. Dehydrated powder of Pleurotus ostreatus grown in
Cuba has a rich nutritional composition and a large number of therapeutic properties. However,
technological parameters (e.g. rheological), as well as biochemical and microbiological quality
control standards for its use as a raw material in the manufacture of solid dosage forms with
nutraceutical and biopharmaceutical applications have not been established yet.

Objective:

The study aims to determine the technological, biochemical and microbiological quality
parameters of dehydrated Pleurotus ostreatus powder.

Method:

Rheological properties (Carr´s index, Hausner´s ratio, angle of repose and flow rate)
were determined in seven batches of mushroom powder. Biochemical and microbiological analyses
were performed using standard methods. Other physicochemical properties (mean particle
size, pH and moisture) were also determined.

Results:

Technical parameters showed a mean particle size of 224.08±7.96 μm, Carr´s compressibility
index (23.08-26.58%), Hausner´s ratio (1.30-1.36), angle of repose (36.6-41.90°) and flow
rate (3.69-6.93 g cm-2 s-1), typical of materials with poor flowability. Biochemical analyses indicated
significant nutraceutical composition: protein (25.0-30.4%), carbohydrate (45-60%), ash
(6.1-9.8%), fiber (5-9%), β-D-Glucans (1.47-1.61%), iron (21-50 mg/100 g), zinc (3.8-8.0
mg/100 g), and polyphenols (123-160 mg/100 g). Moisture content was ≤3.50% and microbiological
analyses were in agreement with ISO standards.

Conclusion:

Dehydrated P. ostreatus powder exhibits good nutraceutical composition and microbiological
quality. Technological parameters evidenced poor flow properties, suggesting the
need to include excipients to improve the rheological properties for applications as an active ingredient
in solid dosage forms for health benefits.
A Comprehensive Review on Anti-obesity Potential of Medicinal Plants and their Bioactive Compounds
Authors: Joshi Bhuwan Chandra , Verma Piyush , Bairy Partha Sarathi
Published: February 2022

Background:

Obesity is a complex health and global epidemic issue. It is an increasing global health challenge covering high social and economic costs. Abnormal accumulation of fat in the body may increase health risks, including diabetes, hypertension, osteoarthritis, sleep apnea, cardiovascular diseases, stroke, and cancer. Synthetic drugs available in the market are reported to have several side effects. Therefore, the management of obesity needs to involve the traditional use of medicinal plants, which helps in searching for new therapeutic targets and supports the research and development of anti-obesity drugs.

Objective:

This review aimed to update the data and provide a comprehensive report on currently available knowledge regarding medicinal plants and phytochemicals constituents reported for their anti-obesity activity.

Methodology:

An electronic search of the periodical databases, like Web of Science, Scopus, Pub- Med, Scielo, Niscair, ScienceDirect, Springerlink, Wiley, SciFinder, and Google Scholar with information reported during 1991-2019, was made to retrieve published data.

Results:

This review attempts to list the medicinal plants with anti-obesity activity. It focuses on plant extracts, isolated chemical compounds, their mechanism of action, and preclinical, experimental model, and clinical studies for further scientific research.

Conclusion:

This review summarizes the medicinal plants and their constituents reported for the management of obesity. The data will fascinate the researcher to initiate further research that may lead to the discovery of a drug for the management of obesity and its associated secondary complications. Several herbal plants and their respective lead constituents have been screened by preclinical in-vitro and in-vivo clinical trials and were found to be effective in treating obesity. Therefore, there is a need to develop and screen a large number of plant extracts, and this approach can surely be a driving force for discovering anti-obesity drugs from medicinal plants.

Authors: Becerril-Navarrete Arubi , Gómez-Romero Mariela , Lindig-Cisneros Roberto , Blanco-García Arnulfo , Villegas Javier , Pineda-García Fernando
Published: February 2022

Antecedentes y Objetivos: Los disturbios antropogénicos o naturales pueden ser tan fuertes que para recuperar sitios degradados se requiere de intervención. Una forma de facilitar el proceso de recuperación es mediante el uso de especies nativas adaptadas al ambiente local, pero aún existe desconocimiento sobre su desempeño. Asimismo, el establecimiento de interacciones con hongos micorrícicos puede contribuir a tener un mayor éxito en supervivencia y crecimiento de especies empleadas en la restauración. El arbusto Tecoma stans es una especie nativa con potencial para restauración, ya que se considera que tiene resistencia al estrés. Por lo tanto, en el presente estudio se exploró si establece interacciones con hongos micorrícicos y una bacteria, y si esto tiene efectos sobre su crecimiento.
Métodos: Se estableció un experimento en condiciones semicontroladas, para lo cual se germinaron sus semillas y las plántulas se inocularon con hongos micorrícicos (Rhizophagus intraradices, Pisolithus arhizus y Scleroderma verrucosum) y con una bacteria (Azospirillum brasilense). Después de seis meses de crecimiento en los tratamientos de inoculo se cuantificó la tasa relativa de crecimiento, se estimaron rasgos morfofuncionales de la raíz y la parte aérea, y se midió el grado infección en las raíces.
Resultados clave: Detectamos que todos los hongos infectaron las plántulas y cada uno afectó de forma distinta el crecimiento y los rasgos morfofuncionales. En la inoculación con S. verrucosum las plántulas crecieron más, tuvieron más hojas, una mayor copa y un sistema radicular de mayor volumen y con raíces de mayor diámetro.
Conclusiones: Los resultados indican que el uso de hongos micorrícicos contribuiría al éxito del establecimiento de T. stans en la restauración, ya que promueve su crecimiento y características que potencialmente permitirían a la especie una mayor capacidad de ganancia de recursos.
O ENSINO NUMA ESCOLA PLURAL
Authors: Monteiro Miguel Corrêa
Published: February 2022

É inegável que a educação inter/multicultural tem vindo a ganhar uma importância cada vez maior devido, em parte, ao próprio fenômeno do racismo na Europa, que tem sido, no nosso entender, provocado pelas políticas de imigração mal reguladas e não integradoras, em parte derivadas da própria lógica cega de mercado associada ao fenômeno da globalização. A mudança que a escola confronta é correlativa da mudança em curso nas sociedades ocidentais – a passagem de sociedades de figurino predominantemente nacional e relativamente estáveis na sua fisionomia sociocultural da primeira metade do século XX, às sociedades características do pós anos 1960, crescentemente multiculturais e multiétnicas, numa sociedade global onde as fronteiras se esbatem, onde a circulação de informação e de pessoas é uma constante, onde os níveis de bem-estar subiram, mas os fenômenos de exclusão se agravaram.

Authors: Al-Jamrah Khaled Mohammed , Nassar Abdulkareem , Mohathab Ibrahim , Al Amad Mohammed
Published: February 2022

Background

Dengue fever (DF) has re-emerged in Yemen with a higher frequency during the last years. On November 6, 2019, an increased number of suspected DF cases in Al-Garrahi district was reported. On November 7, 2019, a team was sent to investigate.

Objective

This study aims to confirm the existence of an outbreak, describe the outbreak characteristics, and recommend suitable intervention for control.

Methods

A descriptive study was conducted. The World Health Organization case definition was used to identify patients. An active search from house to house, along with entomological investigation and health education, was conducted. A line list was used to collect data. Blood specimens were collected and tested by enzyme-linked immunosorbent assay for dengue IgM. Frequency, percentage, and rates were calculated, and the population from the central statistical organization was used.

Results

A total of 2067 cases met the case definition. Of them, 51% were males and 32% were aged <10 years. All patients complained of fever, headache, and arthralgia (100%), followed by myalgia and retro-orbital pain (67% and 39%, respectively). The first case patient was in week 41, and the peak was reached with 1058 patients in week 46. The overall attack rate was 16 of 1000, significantly higher among patients aged 10 years to <50 years and ≥50 years compared with patients aged <10 years (17 and 19/1000 vs 14/1000; P<.001). Of 20 tested blood samples, 12 (60%) were IgM positive. The house index was 70%, the container index was 50%, and the Breteau index was 140. Vector control measures with community participation were intensified in week 46, and patient cases decreased to 140 in week 48.

Conclusions

A dengue outbreak was confirmed in Al-Garrahi district. The spread of infection was facilitated by storing water and the presence of indoor larvae. The findings emphasize the importance of health awareness and community participation for containing DF outbreaks.
PASSION Project: Data Collection in Madagascar and Guinea
Authors: Rabenja Fahafahantsoa Rapelanoro
Published: February 2022

Background

Little data on dermatological conditions presenting on African skin are currently available. This is partly due to the lack of dermatologists in African countries, such as Madagascar and Guinea. There are only 13 dermatologists in Madagascar, or one dermatologist for every 2 million inhabitants. By contrast, the prevalence of common dermatosis is constantly increasing, especially among the pediatric population. According to the World Health Organization, 80% of these skin problems in Africa are grouped into the following 5 pathologies: atopic dermatitis, dermatophytosis, scabies, impetigo, and insect bites.

Objective

In the face of this dilemma, artificial intelligence (AI) is a better tool to collect data on a national scale. Madagascar began participating in the PASSION project in June 2020 and Guinea began participating in January 2021. They join other countries, like Switzerland, Australia, China, India, and Tanzania, who are also using AI in dermatology. This study mainly aimed to compare the 5 pathologies according to the different phototypes characterizing these countries and to collect cases on a national scale that will form a national database. The aim of the data collection is to add 1000 cases per year to the database.

Methods

To increase the number of cases included in phototypes III to VI, two countries were included. A total of 6 data collection sites were set up in Madagascar and one was set up in Guinea. Patients were recruited during dermatology consultations. All patients presenting the 5 pathologies were included. A total of 3 platforms were used to collect data: my.crf.one, IntelliStream, and Derma2go.

Results

A total of 323 cases are currently included in the database for Madagascar, including 76 cases of scabies, 111 cases of atopic dermatitis, 94 cases of dermatophytosis, 35 cases of impetigo and 11 cases of insect bites. The patients’ ages ranged from 2 months to 68 years. A male predominance was noted, with a sex ratio of 1.19 (109 males and 91 females). Phototypes ranged from III to VI. For Guinea, 178 total cases included 32 cases of scabies, 26 cases of atopic dermatitis, 92 cases of dermatophytosis, 3 cases of impetigo, and 25 cases of insect bites. Patients’ ages ranged between 1 year and 70 years, with a male predominance, a sex ratio of 1.54 (108 males and 70 females), and a predominance of phototype VI.

Conclusions

AI is a data collection solution in Africa. However, high bandwidth is needed to employ AI.

Published: February 2022

The curing kinetics of the epoxy resin crosslinked by an anhydride hardener with and without plant fibers was investigated. The epoxy composites containing modified pineapple leaf fiber (EASF), banana fiber (EBSF), and bamboo chopsticks fibers (ECSF) were analyzed by non-isothermal differential scanning calorimetry (DSC) technique. Dynamic methods were used to predict the total heat of reaction of the epoxy resin and its activation energy based on the methods of Kissinger and Ozawa. The results showed that, at a low heating rate (5 °C/min), the ΔH of the pure epoxy, EASF, EBSF, and ECSF were 326.2, 307.6, 295.6, and 366.6 J/g, respectively. The curing rate increased, and the activation energy was decreased due to the catalytic role of hydroxyl groups of plant fibers. Based on Kissinger and Ozawa methods, the calculation of activation energy for pure epoxy was 70.08 kJ/mol and 73.21 kJ/mol, EBSF was 68.07 kJ/mol and 71.41 kJ/mol, ECSF was 60.11 kJ/mol and 63.87 kJ/mol, and EASF was 58.71 kJ/mol and 62.49 kJ/mol. The activation energy for the three kinds of epoxy composite modified fibers was less than pure epoxy resin due to the gel effect resulting from the higher viscosity, faster curing rate, and steric hindrance.

Published: February 2022

The existence of phytochemicals in Cosmos caudatus Kunth, predominantly phenolic compounds, offers several health benefits. Nevertheless, the bioactive compounds are usually susceptible to degradation, and therefore may reduce their biological activity. This work aims to carry out microencapsulation of C. caudatus K. extracts by spray drying technique. The in vitro alpha-amylase inhibitory activity of the microencapsulated product is also investigated. The effect of manufacturing conditions, including pH, the concentration of wall materials, and stirring time, was evaluated. The optimal conditions for microcapsules formation were selected based on the activity of microcapsules as inhibitors for the alpha-amylase enzyme, pointing out by the lowest number of IC50. Results showed that microcapsules prepared in pH 4, 0.05% of chitosan, and 90 min stirring time had optimum efficiency, with the IC50 value of 92.85 ± 1.21 μg/mL. The FTIR (Fourier-Transform infrared) analysis showed that the –C–N stretching amine functional group appeared at wavenumber 1285 cm–1, and the –P=O phosphate bending appeared at 1206 cm–1. Characterization with PSA (particle size analyzer) and SEM (scanning electron microscope) indicated that microcapsules had predominantly spherical forms with a mean diameter of 38.92 μm. This work confirms the important role of microencapsulation in developing plant extracts with retained biological functionalities.

Rostros de la agenda setting durante la Covid-19 en Cuba: un estudio de caso
Authors: Gómez González Gretchen , Muñiz Zúñiga Viviana
Published: February 2022

El presente estudio tiene como categoría principal de análisis a los factores internos y externos que inciden en la construcción de la agenda mediática, como el conjunto de elementos objetivos y subjetivos, propios o ajenos al ámbito institucional de la producción mediática que inciden en las relaciones recíprocas fuente-medio. El objetivo del presente trabajo es analizar. las influencias internas y externas que inciden en la construcción de la agenda mediática del programa En línea contigo, el de mayor teleaudiencia de Santiago de Cuba, durante los dos últimos meses del año 2020, y su relación con las agendas política y pública. Su principal aporte radica en el análisis de la relación inter-agendas en un contexto mediático singular, donde los medios de comunicación se subordinan editorialmente al Partido Comunista de Cuba; y un contexto económico y social marcado por la alta incidencia de COVID-19en el país. A través de un diseño mixto secuencial, se utilizaron métodos como el inductivo-deductivo y el de análisis-síntesis, y técnicas como la investigación bibliográfica y documental, la entrevista, la encuesta, el análisis de contenido, la observación y los grupos de discusión. Los principales resultados corroboran la falta de relación temática entre las agendas política, mediática y pública en la provincia, así como la escasa participación de las audiencias en la etapa de producción del programa En línea contigo. Como limitaciones del estudio se halla las formas de medir las agendas a falta de agencias que pemitan hacerlo con otros procederes a gran escala.

Se procedió a analizar las conductas alimentarias de riesgo y la percepción de la imagen corporal en 53 gimnastas chilenas de nivel elite (50% del total nacional) a través de la aplicación del Eating Attitude Test (EAT – 26), el Body Shape Questionaire (BSQ) y grupos focales. Un 67,9% demostró no manifestar preocupación por la imagen corporal, 15,1%, manifestó preocupación leve, 13,2% manifestó preocupación moderada y 3,8% preocupación extrema. De igual manera un 67,9% no presenta riesgo de conducta alimentaria y 32,1% sí manifiesta esta condición. Existe relación entre las conductas alimentarias de riesgo y la percepción de la imagen corporal (p=0,028). Los grupos focales revelaron que las gimnastas señalan estar incómodas con su figura y que, en su alimentación dejan de lado algunos nutrientes, indican además que sus entrenadores dan instrucciones u opiniones sobre la figura de sus gimnastas de formas “no adecuadas” y con “poco profesionalismo”. Reconocen además no estar conformes con su imagen y manifiestan preocupación por la opinión de terceros.

La apicultura en México se sostiene con subespecies de abejas (Apis mellifera L) europeas y africanizadas. Debido a la dificultad en la diferenciación morfológica de las poblaciones Europeas (E) y Africanizadas (A) de A. mellifera, el objetivo de este trabajo fue realizar un análisis comparativo entre la técnica morfométrica FABIS, contra el diagnóstico empleando el polimorfismo en la longitud de los fragmentos de restricción (RFLP) del ADN mitocondrial (ADNmt). Se emplearon muestras de abejas procedentes de 135 colonias comerciales (CC), 15 colonias pie de cría (CPC) y 3 colonias silvestres (CS) localizados en diferentes municipios del estado de Tabasco (N=153). Ambos métodos de diagnóstico, identificaron a las CPC como europeas y las CS como africanizadas, pero en las CC el método FABIS no pudo definir 9 colonias, dándolas como sospechosas (S) y otras 50 no coincidieron con el resultado del método molecular, por lo que, en total ambos métodos coincidieron en 94 identificaciones (61.44 %). El agrupamiento bayesiano basado en el análisis de las doce variables morfométricas mostró que las categorías A-CC y E-CC, forman un grupo cercano a la categoría E-CPC; mientras que la categoría A-CS presentó la mayor distancia formando un grupo aislado. Por lo tanto, abejas de CC tienen características morfométricas tendientes a abejas E-CPC. Este trabajo también pretende ser una contribución a la falta de registros sobre la africanización en el estado de Tabasco. Se recomienda emplear el método molecular para discriminar entre abejas E/A, por no estar afectado por los factores ambientales.

El parasitismo causado por estrongilidos es uno de los principales factores limitantes de la producción de Cabras Criollas en el Este de Cuba. Mediante una investigación descriptiva y exploratoria realizada durante el periodo comprendido entre los años 2013 y 2018, fueron identificados los factores que regulan la dinámica epizootiológica de las estrongilosis gastrointestinales en 18 rebaños. Los factores bajo control fueron: la dinámica de población de larvas por mes, los estados reproductivos y el proceso de crecimiento de las cabras. Se registró la dinámica mensual de larvas infestivas en el pasto. Se aplicaron ANOVAS simples para modelos lineales correspondientes a cada factor y la prueba de Newmankeuls para comparaciones múltiples de media. Se observó que las dinámicas parasitarias de las estrongilosis gastrointestinales, que afectan a las cabras Criollas Cubanas, están relacionadas con procesos fisiológicos y zootécnicos. En estas dinámicas se identificaron dos momentos críticos o picos de infestación: en los animales en crecimiento durante el periodo de destete (2,188 huevos por gramo, HPG) y en las reproductoras en periodos de periparto (972 HPG). La infestación general de los rebaños está condicionada por la combinación de mayor ingestión de larvas infestivas, procesos de estrés alimentario y estados fisiológicos predisponentes, que conducen a picos de infestación estacionales entre los meses de diciembre a febrero superiores a 1,500 HPG. La dinámica de infestación del pasto está relacionada con la estacionalidad lluviosa con picos de infestación entre los meses de julio a septiembre y un máximo promedio de 1,200 larvas por kilo de pasto.
