KORELASI KADAR FENOLIK DAN FLAVONOID TOTAL TERHADAP AKTIVITAS ANTIOKSIDAN BEBERAPA EKSTRAK DAUN AFRIKA (Venornia amygdalina Delile.) MENGGUNAKAN METODE FRAP (Ferric Reducing Antioxidant Power)
Authors: Suhendy Hendy , Afdal Alif  , Ira Rahmiyani  
Published: May 2022

Secara empiris Daun Afrika memiliki potensi antioksidan yang tinggi dengan kontributor utama aktivitas tersebut yaitu senyawa golongan polifenol, sedangkan secara ilmiah ekstrak etanol Daun Afrika termasuk kategori sangat lemah. Penelitian ini bertujuan untuk menentukan aktivitas antioksidan beberapa ekstrak Daun Afrika dan korelasinya dengan kadar fenolik dan flavonoid total. Simplisia diekstraksi dengan maserasi bertingkat menggunakan pelarut yang berbeda kepolaran. Fenolik total dihitung dengan metode pourmorad dengan pembanding asam galat sedangkan flavonoid total menggunakan metode Chang dengan pembanding kuersetin. Aktivitas antioksidan ekstrak diuji dengan metode FRAP menggunakan Sektrofotometer UV-Vis. Fenolik total ekstrak n-heksana, etil asetat dan methanol daun Afrika berturut-turut sebesar 0,93; 1,30 dan 3,47 g GAE / 100 g, sedangkan flavonoid totalnya sebesar 0,20; 0,58 dan 0,31 g QE / 100 g. Nilai EC50 asam askorbat, ekstrak n-heksana, etil asetat dan methanol daun Afrika berturut-turut sebesar 5,86; 717,50; 740,28 dan 1800,46 µg/ml. Korelasi pearson menunjukkan bahwa nilai Nilai EC50 ekstrak Daun Afrika dipengaruhi oleh fenolik dan flavonoid total (p<0,01) dimana karena rendahnya kadar kedua senyawa golongan tersebut diduga menyebabkan aktivitas antioksidan ekstrak-ekstrak Daun Afrika sangat lemah.
Near-infrared Spectra of the Inflated Post-common Envelope Brown Dwarf NLTT 5306 B
Authors: Buzard Cam , Casewell Sarah L. , Lothringer Joshua D. , Blake Geoffrey A. 
Published: May 2022

Abstract
NLTT 5306 is a post-common envelope binary made up of a white dwarf host and brown dwarf companion that has shown evidence of inflation and active mass donation despite not filling its Roche lobe. Two proposed mechanisms for the brown dwarf’s inflation are magnetic interactions and a high-metallicity, cloudy atmosphere. We present moderate-resolution (R ≲ 2000) J-band Keck/NIRSPEC observations of this system. These phase-resolved data allow us to constrain differences between atmospheric parameters of the day- and nightside of the brown dwarf. Our day- and nightside effective temperature measurements are consistent, in agreement with the brightness temperatures measurements from Casewell et al. The dayside favors a slightly lower surface gravity, perhaps stemming from the material streaming between the two objects. Finally, our data show a preference for low-metallicity models. This would be expected from the system’s old age, but provides direct evidence that a high-metallicity, cloudy brown dwarf atmosphere is not responsible for the witnessed inflation. These results strengthen the case for magnetic interactions leading to inflation of NLTT 5306 B.
Nuclear Matter and Neutron Stars from Relativistic Brueckner–Hartree–Fock Theory
Authors: Tong 童 Hui 辉 , Wang 王 Chencan 宸璨 , Wang 王 Sibo 锶博 
Published: May 2022

Abstract
The momentum and isospin dependence of the single-particle potential for the in-medium nucleon are the key quantities in the Relativistic Brueckner–Hartree–Fock (RBHF) theory. It depends on how to extract the scalar and the vector components of the single-particle potential inside nuclear matter. In contrast to the RBHF calculations in the Dirac space with the positive-energy states (PESs) only, the single-particle potential can be determined in a unique way by the RBHF theory together with the negative-energy states, i.e., the RBHF theory in the full Dirac space. The saturation properties of symmetric and asymmetric nuclear matter in the full Dirac space are systematically investigated based on the realistic Bonn nucleon–nucleon potentials. In order to further specify the importance of the calculations in the full Dirac space, the neutron star properties are investigated. The direct URCA process in neutron star cooling will happen at density ρ

for potential Bonn A, B, C. Compared with the results obtained in the Dirac space with PESs only, the full-Dirac-space RBHF calculation predicts the softest symmetry energy, which would be more favored by the gravitational wave detection of GW170817. Furthermore, the results from the full-Dirac-space RBHF theory are consistent with the recent astronomical observations of massive neutron stars and simultaneous mass–radius measurement.
Assessment of the methylene blue mediated photodynamic therapy on BCL2 and BAX genes expression at mRNA level and apoptosis of head and neck squamous cell carcinoma cell line
Authors: Kahalian Shadi , Koopaie Maryam , Hakimiha Neda , Kolahdooz Sajad 
Published: May 2022

Aim: This study aimed to assess the effect of photodynamic therapy (PDT) on apoptosis of head and neck squamous cell carcinoma (HNSCC) cells by flow cytometry and evaluating BAX and BCL2 genes expression.
Materials and methods: In this in vitro study, human HNSCC cell line (HN5; NCBI. C196) was used and after cell culture, they were divided into four groups: controls (group C), cells irradiated by a diode laser with a wavelength of 660 nm, 150 mW power, and 45 J/cm2 energy density (group L), cells treated by methylene blue (group MB), and cells treated using PDT (group MB plus L). The RNA was then extracted and subjected to quantitative reverse transcription polymerase chain reaction (qRT-PCR) to assess BCL2 and BAX genes expression. Flow cytometry analysis was performed to assess apoptosis. Data were analysed using ANOVA.
Results: PDT caused significant down-regulation of BCL2 (p&lt;0.001) and significant overexpression of BAX (p&lt;0.05) and PDT induced apoptosis HNSCC cell line. Changes in expression of these genes were not significant in other groups (p&gt;0.05).
Conclusions: Considering the down-regulation of BCL2 and overexpression of BAX after PDT using a 660-nm diode laser and MB with 3.2 µg/mL concentration and flow cytometry results, it is suggested that this modality can be introduced for induction of apoptosis in the HNSCC cell line.
Quelles explications sexuelles peut-on donner aux adolescents ?
Authors: Benmansour Maryan 
Published: May 2022

Résumé Le propos de cet article est inspiré par l’expérience et la pratique de groupes de parole avec des adolescents : si l’on veut les soutenir dans leur effort pour penser leur propre sexualité, il faut parvenir à se défaire de la position de « V »érité qui soutient tout discours sur le sexe et la sexualité, qu’ils soient scientifiques ou éthiques. Il est possible de s’appuyer sur ce que l’on pourrait nommer des théories sexuelles adolescentes pour permettre l’effort de pensée et la prise de parole. La prévention ne peut se concevoir sans un espace de confrontation et d’élaboration avec de telles théories et c’est précisément leur écoute par des adultes bienveillants qui permet aux adolescents d’affronter les énigmes de leur sexualité
Éducation à la sexualité en collège : une expérience de terrain
Authors: Hulard Julie 
Published: May 2022

Résumé Si l’éducation à la sexualité est inscrite dans le Code de l’éducation depuis la loi du 4 juillet 2001, l’application de cette directive soulève la question du contenu des séances, des personnes qui les animent, de la responsabilité de l’organisation, ainsi que les moyens alloués. Cet article donne un exemple de mise en œuvre d’un parcours d’éducation à la sexualité de la classe de 6 e à la classe de 3 e dans un collège de la banlieue de Strasbourg et fait part des points d’appuis de l’équipe enseignante mais également des difficultés rencontrées.
Abolitionism and the Antebellum U.S. Women’s Rights Movement: The (Missed) Connections of the First National Woman’s Rights Convention (1850)
Authors: Quanquin Hélène 
Published: May 2022

Bien qu’elle ait été parfois éclipsée par la convention de Seneca Falls de 1848, la Première Convention Nationale pour les droits des femmes qui eut lieu à Worcester, dans le Massachusetts, les 23 et 24 octobre 1850 fut un événement important pour le combat pour les droits des femmes aux États-Unis. Alors que son organisation fut permise par la mobilisation de compétences et de ressources issues de l’abolitionnisme, elle est la preuve que les militantes et militants commençaient à développer un discours sur les droits des femmes qui incluait le droit de vote. Contrairement à ce qui se passa à Seneca Falls, une femme noire, Sojourner Truth, s’adressa à l’assemblée, ce qui montre qu’il existait la possibilité d’un mouvement véritablement inclusif. Cependant, l’utilisation constante de la métaphore de l’esclavage ainsi que la façon dont la présence de Truth fut présentée pendant toute la convention anticipèrent les divisions du féminisme et l’exclusion des Africaines-Américaines du mouvement après la guerre de Sécession.
WH- + TO, why + Ø : le rôle de l’infinitif avec et sans TO dans les interrogatives infinitives
Authors: Dubois-Aumercier Marie 
Published: May 2022

Cet article porte sur les caractéristiques syntaxiques et sémantiques des interrogatives infinitives de l’anglais. Ces propositions, qu’elles soient indépendantes ou subordonnées, sont soumises à de nombreuses contraintes qui les distinguent des interrogatives finies par lesquelles elles peuvent être paraphrasées. Elles ne peuvent en effet pas comporter de sujet exprimé ; elles ne peuvent apparaître que dans certains des environnements dans lesquels les interrogatives finies sont acceptables ; elles ont une valeur modale ; elles ne sont généralement pas considérées comme de vraies questions. Les interrogatives infinitives en why présentent une spécificité supplémentaire : elles comportent un infinitif sans TO lorsqu’elles sont indépendantes et un infinitif avec TO lorsqu’elles sont subordonnées. L’article montre que la théorie avancée par Cotte 1998, selon laquelle TO dit un mouvement vers l’actualisation du procès, permet de rendre compte de ces contraintes et de comprendre ce qui les motive. Il montre également que la spécificité des interrogatives infinitives en why peut être expliquée par l’interaction entre le sens de why , la valeur de la subordination et le contraste entre TO et Ø, qui dit un mouvement de virtualisation inverse à celui codé par TO.

Incursion marine dans le Parc National du Banc d’Arguin (PNBA) : phénomène naturel ou signe d’une élévation du niveau marin ?
Authors: Ly Djibril , Barusseau Jean-Paul 
Published: May 2022

Dans la plaine littorale de la partie no rd du Parc National du Banc d’Arguin (PNBA), est apparue une lagune dénommée Bellaât 1 à la suite d’une rupture localisée du cordon littoral et d’une invasion des espaces situés en arrière cordon. Elle montre depuis une permanence pluriannuelle qui n’avait pas été enregistrée jusqu’ici. Dans le but de situer l’avènement de la rupture de la brèche, d’en comprendre les causes mais aussi ses conséquences sur le milieu, plusieurs missions de suivi ont été réalisées par les autorités du PNBA. Cette contribution se propose de restituer les résultats préliminaires de ces travaux. Elle se veut un « signal » à l’endroit des autorités mauritaniennes qui doivent porter un regard précautionneux sur les éventuelles incursions marines dans les zones urbanisées du littoral du pays.
Brussels Studies: 15 jaar en 1,5 miljoen downloads. Momentopnames van een stad en een lokaal wetenschappelijk tijdschrift
Authors: Debroux Tatiana , Hardy Margaux 
Published: May 2022

Brussels Studies a récemment fêté ses 15 ans. Si son projet éditorial – offrir à un public large une plateforme trilingue de publications scientifiques sur et pour Bruxelles – demeure inchangé depuis 2006, de nombreuses adaptations ont pris place au fil des années et des 168 articles publiés à ce jour. La revue a ainsi réussi à rencontrer un lectorat varié au fil des ans venant à la fois du monde académique, des administrations et pouvoirs publics ou encore du milieu associatif. Brussels Studies constitue de fait un exemple assez exceptionnel, faisant de Bruxelles l'une de rares villes au monde disposant d'une revue scientifique qui lui est dédiée. À travers quelques faits et figures synthétiques, cette fact sheet offre un regard rétrospectif sur l'écosystème éditorial de la revue, les caractéristiques des textes publiés et l'impact qu’ils ont pu avoir sur les débats et l'action publique.
Cranial Autonomic Symptoms in Migraine
Authors: Tiwari Ashutosh , Maurya Pradeep K. , Qavi Abdul , Kulshreshtha Dinkar , Thacker Anup K. , Singh Ajai K. 
Published: May 2022

Objective:
Our aim was to observe frequency of cranial autonomic symptoms (CAS) in migraineurs (primary) and its relation with laterality of headache or other factors, if any.

Background:
Migraine episodes have headaches with or without aura, and sometimes associated with systemic autonomic nervous system symptoms. Primarily presence of cranial autonomic symptoms suggests diagnosis of TACs. But many studies reported cranial autonomic symptoms (CAS) ranging from 26% to 80% in migraine patients.

Material and Methods:
Consecutive patients of migraine attending our headache clinic were included in our study. Presence of CAS was recorded with respect to ocular, nasal, facial and aural symptoms along with headache characteristics and laterality information. Detailed clinical examination was performed. We used ICHD 3 (beta version) criteria.

Results:
Our study cohort comprised of 200 patients having mean (± SD) age 31.12 (± 10.67) years. There were 157 (78.5%), females. Out of 200 patients, 148 (74%) were having at least one CAS, of which 70% were having 2 or more CAS. Frequency of CAS was lacrimation (45.5%), conjunctival injection (34.5%), eyelid edema (34%), aural fullness (27.5%), facial sweating (25%), facial flushing (17.5%), nasal congestion (9%), rhinorrhea (5%) and ptosis (4%). Bilateral CAS was present in 129 (87%) and unilateral CAS in 19 (13%) (OR 35.31; 95% CI 9.19 to 135.7), (P < 0.0001). Sunlight as a trigger was present in all 148 (100%) patients.

Conclusion:
Our study showed that CASs in migraine is common and bilateral. Sunlight triggers headache in almost all CAS positive patients.
Mismatch repair protein deficiency assessed by immunohistochemistry in sporadic colorectal carcinoma
Authors: Adhikari Cynthia , Bandyopadhyay Ranjana , Bandyopadhyay Ujjwal , Sarkar Snigdha , Basu Keya 
Published: May 2022

Context:
Globally, colorectal carcinoma (CRC) ranks the third most commonly diagnosed malignant disease, one of the leading causes of cancer deaths.

Aims:
To study the spectrum of clinicopathological characteristics of sporadic colorectal carcinoma and to assess mismatch repair gene deficiency by the expression pattern of the proteins assessed by immunohistochemistry.

Setting and Design:
Observational study conducted in a tertiary care hospital in West Bengal.

Materials and Methods:
Fifty-two surgically resected specimens of CRC received from January 2018 to May 2019 were studied for clinical, morphological, MSI status.

Statistical Analysis Used:
IBM SPSS 23.

Results:
A total of 50% of the cases belonged to younger and 50% to the older population, with male predominance being 53.8%. The most common histologic type was adenocarcinoma (88.5%). The majority was found to be well-differentiated carcinoma (50%). The majority cases were of the T3 stage accounting to 38.5%. A total of 24 out of 52 cases (46.15%) had an absent expression of at least one mismatch repair (MMR) protein. A significant correlation was found between the young age group and microsatellite instability (MSI) with a P value of 0.001. A significant association was found between MSI and tumor differentiation with P value of 0.018. A significant association was found between MSH6 and histological type with P value of 0.012. A significant association was found between MSI and tumor stage with P value of 0.032.

Conclusions:
This study shows a significantly higher number of sporadic colon cancers involving the young age group, and younger cases showed significant association with MSI. This alarming trend needs validation by studies involving larger populations and can be helpful prognostically as well as in formulating chemotherapeutic regimens.
In-Person Versus Virtual Musculoskeletal Ultrasound Education during the Coronavirus Disease 2019 Pandemic
Authors: Chen Ya-Ting , Chou Raymond , Kohler Minna J. , Eng Christine , Borg-Stein Joanne 
Published: May 2022

Background:
Musculoskeletal ultrasound (MSKUS) curricula in physical medicine and rehabilitation (PM and R) residency programs have traditionally relied on in-person teaching workshops. However, the social distancing requirements during the coronavirus disease 2019 pandemic has led to a growing interest in remote ultrasound education.

Aims:
The aim of the study is to assess residents' MSKUS skill confidence after in-person vs. virtual MSKUS teaching workshops in a PM and R residency program.

Materials and Methods:
Twenty-one PM and R residents at a single academic center were assigned to either an in-person MSKUS demonstration by a sports medicine faculty member (n = 10) or a real-time virtual demonstration (n = 11) for workshops of the knee and wrist and hand. Surveys using Likert scales were employed to assess the change in residents' confidence with performing MSKUS examinations and their satisfaction with the curriculum.

Results:
There was a significant increase in confidence scores from baseline to postworkshop for both the virtual and in-person groups. The linear mixed effect model showed that there were no significant differences between the virtual and in-person groups for their baseline, postworkshop, and changes in confidence scores. All participants were satisfied with the updated curriculum.

Conclusions:
With the ongoing pandemic, incorporating virtual teaching platforms into existing MSKUS curricula is feasible and may provide similar improvements in residents' skill confidence as the in-person workshops. Successful implementation requires consideration of several factors, including ultrasound machine availability, participants' familiarity with technology, and the quality of the virtual streaming platform. A multi-institutional randomized controlled trial can further evaluate the effectiveness of remote MSKUS education for PM and R trainees.
Sobreexposición e hipersexualización para vender más: percepciones y actitudes sociales sobre las preadolescentes en comunicaciones comerciales
Authors: Llovet Rodríguez Carmen , Narros González María José , Díaz-Bustamante Ventisca Mónica , Ruiz-SanRomán José A. 
Published: May 2022

Introducción. Las preadolescentes siguen patrones de las influencers para su entretenimiento, y pueden imitar la exhibición pública de contenido personal como forma de venta en su proceso de socialización. Objetivo. Este artículo analiza las percepciones y actitudes de la sociedad española sobre las representaciones de las menores en las comunicaciones comerciales. Metodología. Se ha realizado una encuesta telefónica a 346 hogares en toda España entre 18 y 65 años. Resultados. en 8 de cada 10 hogares se percibe que las preadolescentes sobreexponen fácilmente su imagen (78,7%), dan mayor valor a su aspecto físico que a otros aspectos (78,8%) y asumen patrones adultos de comportamiento (77,7%). Respecto a su representación en comunicaciones comerciales, se piensa que la publicidad muestra una imagen de ellas mucho mayores de lo que son (86,4%), idealizada (84,8%) e hipersexualizada con el objetivo de vender más (83,1%), y que los estilismos no son acordes con la edad de las preadolescentes (73,7%). Conclusiones. La percepción global de las preadolescentes en la sociedad española es de una aceptación generalizada de imagen irreal, idealizada y de mayor edad que las hace vulnerables. Recomendaciones. Por su uso elevado, frecuente y exclusivo de los medios digitales es necesario que los preadolescentes desarrollen competencias que les den acceso a un capital cultural más relevante. La alfabetización digital puede ser un factor de inclusión social al desarrollar valores que fomenten su integración como sujetos críticos y activos.
Trends in the occurrence of Helicobacter pylori infection in Arada Sub-City: A 5-year retrospective study.
Authors: Birru Haile Tamrat , Gelana Tiki Tegenu 
Published: May 2022

Helicobacter pylori infection remains a major public health problem in Ethiopia. This retrospective study aims at determining the prevalence of H. pylori infection over a period of 5 years, from 2016 to 2020 among dyspeptic patients at nine Health Centers of Arada sub-city, Addis Ababa. Data were collected from the patients record books of the nine Health Centers. At the health centers a stool antigen test is most often used than a serology antibody test, because stool antigen test is more specific and detects only an active infection. Chi-square analysis was employed to identify associations between variables. A P-value of <0.05 was considered significant. In the present study, the overall prevalence of H. pylori was 49.2%. The prevalence was higher among patients of age 60 years and above (59%); whereas it was lower in the age category of 15 to 29 years (43%). No association was observed between H. pylori infection and the sex (gender) of the studied cases. However, statistically significant increments in H. pylori cases were observed over the five year study periods. It can be concluded that the overall prevalence of H. pylori was 49.2% and there were no associations between sex (gender) and H. pylori infection. The authors would like to recommend the health centers to use stool antigen test and to provide an awareness for the study population.
