Inhibitory activity of CXCR4 attenuates intervertebral disc degeneration by regulating TXNIP/NLRP3 expression
Authors: Yu Jie , Tao Xiaohui
Published: May 2023

Purpose: To explore the inhibitory effect and mechanism of action of CXCR4 on intervertebral disc degeneration.Methods: The expression of CXCR4 was assessed in different degrees of degenerate disc tissues. Nucleus pulposus (NP) cells-induced degeneration were obtained using interleukin 1 beta (IL-1β) stimulation. CXCR4 inhibitor, AMD 3100, was employed to resist the function of CXCR4, in order to determine whether CXCR4 inhibition acted by targeting TXNIP/NLRP3 axis.Results: Expression of CXCR4 increased in severely degenerated disc tissues. IL-1β activated and promoted the progression of intervertebral disc degeneration, but AMD3100 treatment reversed the effects of IL-1β. Moreover, TXNIP and NLRP3 were significantly suppressed by AMD3100 stimuli.Conclusion: The results demonstrate that inhibition of CXCR4 prevents NP cells from degradation by regulating TXNIP/NLRP3 signaling pathway, thus indicating that this approach could be effective in the management of intervertebral disc degeneration.

Published: May 2023

Purpose: To examine the effect of nicorandil on high glucose-induced cardiomyocyte inflammation and oxidative stress.Methods: H9C2 cardiomyocytes were divided into control group, high glucose group and nicorandil group. The survival rate of cardiomyocytes was determined using the CCK-8 method. The contents of reactive oxygen species (ROS) of cardiomyocytes were determined by flow cytometry. The contents of MDA and LDH in cell supernatant were determined by kit. Western blot and real-time PCR were used to assess oxidative stress, inflammation and apoptosis related factors in each group of cardiomyocytes. The expression levels of IL-1β were determined by immunofluorescence. Tunnel staining was used to determine the apoptosis level of each group.Results: The expressions of SOD1 and SOD2 in the high glucose group were significantly decreased (p < 0.05). Also, the contents of MDA and LDH were significantly increased (p < 0.05). Furthermore, IL-1β, TNF-α, caspase 3 and Bax expressions were increased, while Bcl-2 expression was inhibited. IL-1β and Tunnel fluorescence also increased significantly. NF-κB and Ikkα were significantly increased, while IκB-α was inhibited. Furthermore, nicorandil inhibited oxidative stress and apoptosis, as well as NF-κB pathway and downstream factor Ikkα.Conclusion: Nicorandil ameliorates the inflammation and oxidative damage of cardiomyocytes induced by high glucose, by inhibiting NF-κB pathway, thereby lowering apoptosis. Thus, the findings provide new insight into the development of new agents for the treatment of diabetic cardiomyopathy.

Purpose: To investigate the anti-sickling activity of Senna alexandrina, Aerva javanica, and Ficus palmate extracts. Methods: The leaves were extracted with water and methanol. The anti-sickling effect of extracts was determined using blood from 20 sickle cell disease (SCD) patients by mixing it with 500 and 1000 μg/mL of extract. The treated blood samples were then examined under a light microscope. The osmotic fragility of erythrocytes was determined using 4 mL (0 – 0.9 %) buffered saline mixed with 1 mL extract (500 μg/mL) and 0.05 mL sickled red blood cells (RBCs). Results: Aerva javanica extract significantly (p < 0.0001) reduced the percentage of sickle cells compared to control. The sickle-shaped cells were 29.47 % when treated with 125 μg/mL concentration of methanol extract of A. javanica that was further decreased to 0.35 % on increasing the concentration to 500 μg/mL. A similar trend was also observed with extracts of F. palmata. Extracts had protective effect on erythrocyte osmotic fragility. Results of comet assay suggested that extracts did not damage DNA. Conclusion: These plant extracts have promising anti-sickling activity and protect erythrocyte osmotic fragility. However, in vivo studies are required to validate these results and for further development of the extracts for therapeutic use.

Purpose: To study the release behaviour of ciprofloxacin hydrochloride tablet matrices prepared with different polymers in dissolution media of different pH. Methods: Different formulations of slow-release matrix tablets of ciprofloxacin hydrochloride were prepared with polymers, namely, ethyl cellulose (Etc), hydroxyethyl cellulose (Hec), hydroxypropyl methylcellulose (Hpc), and Eudragit® L-100 (Eud) using matrix embedding technique. The matrix tablets were characterized and studies of their dissolution profiles were studied in 0.1 N HCl (pH 1.2) and in simulated intestinal fluid (excluding enzymes) of pH 4.0, 6.0, and 7.4. Results: The tablets had the following characteristics: weight, 659.25 ± 7.96 to 661.65 ± 6.53 mg; hardness, 7.05 ± 0.21 to 9.60 ± 0.40 kgf; friability, 0.212 to 0.292 %; and drug content, 91.47 ± 0.53 to 112.50 ± 4.14 %. In batches prepared with ethyl cellulose, Eudragit L-100, and hydroxypropyl methylcellulose, drug release increased with a decrease in pH. However, matrix tablets prepared with hydroxyethyl cellulose displayed the highest drug release at pH 4.0 with Cmax of 108.75 % and T50% of 30.86 min; thereafter, drug release decreased with increase in pH. The pattern of drug release was Hec > Hpc > Eud > Etc in most media with more drug release in acidic than at alkaline pH. Conclusion: Release of ciprofloxacin from the formulated matrix tablets was pH-sensitive in vitro. This should be taken into consideration in designing sustained release oral form of ciprofloxacin.

Authors: Chen Tianbao , Chen Chengbo , Ji Xiaojun , Zhu Yuanfang
Published: May 2023

Purpose: To determine the impact of Gomisin A (GomA) on myocardial cell damage caused by hypoxia/reoxygenation (H/R). Methods: Various methods, including MTT, western blot and flow cytometry were used to to assess the viability of H9c2 cardiomyocytes and cell apoptosis. Expression levels of various enzymes and cytokines, including superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT), tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β and IL-6 were measured by enzyme-linked immunosorbent assay (ELISA). Western blot was used to evaluate the expression levels of inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2) and Toll-like receptor 4 (TLR4), as well as the phosphorylation of p65 and nuclear factor kappa B (NF-κB) inhibitor alpha (IκBα). Results: Low concentrations of GomA had no toxic effect on H9c2 cells. In H/R-stressed H9c2 cells, GomA increased cell viability and reduced cell apoptosis, suggesting that GomA inhibited H/R-induced cell apoptosis. Additionally, GomA alleviated H/R-induced oxidative stress and inflammation by increasing the expression of SOD and CAT, while decreasing the expression of MDA, iNOS, COX-2, TNF-α, IL-1β, and IL-6. GomA also suppressed the H/R-induced TLR4–NF-κB pathway by reducing the expression of TLR4 and the phosphorylation of p65 and IκBα. Conclusion: These results indicate that GomA is a potential candidate for the treatment of myocardial ischemia/reperfusion (MI/R) injury by increasing cell viability, reducing cell apoptosis, alleviating oxidative stress, and reducing inflammation by inhibiting TLR4–NF-κB pathway.
Socio-centric biases and constructions of otherness: For a critical and reasoned anthropological approach
Authors: Chave-Dartoen Sophie
Published: May 2023

Considering the colonial heritage and the other forms of domination makes it necessary to take a critical approach to the positions of authority on which scientific discourse is based. What would be the conditions for the possibility of knowledge giving access to alternative forms of knowledge and discourse about the world? Does not every approach bring its own biases in the project of universal knowledge? The reflection is based on an ethnographic survey (Wallis) and the current debate on the restitution of African museum collections by former colonial countries.

Retornar a los legados coloniales y a otras formas de dominación hace necesario un enfoque crítico de las posiciones de autoridad en las que se basa el discurso científico ¿Cuáles serían las condiciones de posibilidad de un saber que permita formas alternativas de conocimiento del mundo y de discurso sobre él? ¿No aporta cada enfoque sus propios sesgos al proyecto de un conocimiento universal? La reflexión se basa en una encuesta etnográfica (Wallis) y en el debate actual sobre la restitución por parte de los antiguos países coloniales de las colecciones africanas conservadas en sus museos.

Is the Venus of Milo Japanese?
Authors: Lucken Michael
Published: May 2023

The Venus of Milo is seen as a unique masterpiece of Greek art. However, to the great displeasure of the Greek authorities who are demanding its return, it has belonged to the French public collections since 1821. More generally, it is widely considered a European and Western heritage. And it goes without saying, its beauty is universal. But can it be Japanese? Through the examination of the reception of the Venus de Milo in Japan, the aim is to reflect on the conditions of a utopian appropriation of art works, given that, unlike texts that can be quoted, cut and mounted, paintings and statues are strongly dependant on their materiality. Against the current discourse on the dematerialization of art works, which goes hand in hand with an increasing fetishization of the originals, this article explores the path of an incorporation through practice and repetition.

La Vénus de Milo est considérée comme un chef d’œuvre de l’art grec. Toutefois, au grand dam des autorités helléniques qui en demandent la restitution, elle appartient depuis 1821 aux collections publiques françaises. Plus généralement, on admettra volontiers qu’elle est européenne et occidentale. Et cela va sans dire, sa beauté est universelle. Mais peut-elle être japonaise ? À travers l’examen de la réception de la Vénus de Milo au Japon, il s’agira de réfléchir aux conditions d’une appropriation utopique des œuvres d’art plastiques, étant entendu que, contrairement aux textes qui peuvent être cités, tronqués, réédités, tableaux et statues sont puissamment assujettis à leur matérialité. À rebours des discours actuels sur la dématérialisation des œuvres, qui va de pair avec une fétichisation croissante des originaux, cet article explore le chemin d’une incorporation par l’usage et le refaire.

ミロのヴィーナスは、ギリシャ美術の最高傑作と言われている。しかし、返還を求めるギリシャ政府の大いなる不興を買ったにもかかわらず、1821年以来、フランスの公的コレクションに所蔵されている。より一般的には、それがヨーロッパ的、西洋的であることは容易に認められよう。そして、言うまでもないが、その美しさは普遍的だ。ところで、ミロのヴィーナスは日本的なものといえるだろうか。引用やカットが可能なテキストとは異なり、絵画や彫像はその物質性に強く支配されていることから、日本におけるミロのヴィーナスの受容を通じて、芸術作品の自由な流用の条件について考察する。芸術作品の脱物質化をめぐる言説は、オリジナルのフェティッシュ化とともに進んでいるが、本稿では、実践と再制作による取り込みの道筋を探る。

Sutton Peter & Walshe Keryn, 2021, Farmers or Hunter-gatherers? The Dark Emu Debate, Melbourne University Press, Melbourne, 264 p.

Dark Emu (2014), a book written by Bruce Pascoe, argues for a drastic revision of the vision of Aboriginal peoples at the time of the colonisation of Australia. Traditionally presented as nomadic hunter-gatherers, they were in fact for the most part villagers who applied some forms of agriculture and fish farming, all of which were concealed by those who wanted to appropriate their lands, thus forging a false version perpetuated by anthropological tradition. This provocative thesis has had a huge impact in Australia, where it has been the subject of much controversy. Peter Sutton and Keryn Walshe’s book is the first rebuttal by academic specialists–who are also deeply involved in the defence of the rights of Aboriginal communities.

Le livre Dark Emu (2014), écrit par Bruce Pascoe, plaide pour une révision drastique de la vision des peuples aborigènes au moment de la colonisation de l’Australie. Traditionnellement présentés comme des chasseurs-cueilleurs nomades, ceux-ci auraient en réalité été pour une bonne part des villageois pratiquant certaines formes d’agriculture et de pisciculture, autant d’éléments dissimulés par ceux qui voulaient s’approprier leurs terres, forgeant ainsi une version mensongère perpétuée par la tradition anthropologique. Cette thèse provocatrice a connu un immense retentissement en Australie, où elle a suscité de très âpres polémiques. Le livre de Peter Sutton et Keryn Walshe en constitue la première réfutation émanant de spécialistes académiques –  par ailleurs, profondément impliqués dans la défense des droits des communautés aborigènes.

Introduction: Job satisfaction plays an important part in an employee's professional career. Previous studies have shown that job satisfaction is a significant factor in worker retention and migration. The study aims to identify the job satisfaction level of practicing physical therapists (PT) in the Philippines.
Methods: This was a cross-sectional study among seventy-eight licensed Filipino PTs working in various healthcare setting in the Philippines. The Minnesota Satisfaction Questionnaire was used to measure the job satisfaction through an electronic survey. Other data including demographic and work-related information were collected. Chi-square and Spearman’s correlation were used to establish correlation among the variables.
Results: 77 registered Filipino PTs responded to the survey. Monthly income (rs = 0.438, p < 0.01) and physical Therapist who are working in private and specialty clinics (rs = 0.233, p < 0.05) tends to have higher job satisfaction. PTs practicing in the Philippines were generally not fully satisfied with their job. Monthly income and work sector showed a consistent relationship with overall job satisfaction and its domains.
Discussion: All physical therapists, either working in government or private setting should receive competitive pay to boost their job satisfaction. A better grasp of job satisfaction will allow for changes in local organization policy aimed in increasing job satisfaction of Filipino PTs. Further recommendations include creating opportunities for recognition and reward for physiotherapist skills and experience within the practice and community, as well as improving the delivery of professional development for PTs.

Introduction: The importance of the use of mobile applications in the health practice have grown increasingly over the years. There is a need to assess if these applications can be validly and reliably used in the clinical setting as these are critical measures that evaluate the quality and effectiveness of a tool to improve the delivery of health care in the physical therapy practice. This systematic review aimed to identify and synthesize existing studies on evidence of the concurrent validity and intra-rater, inter-rater, and test-retest reliability of mobile applications used in physical therapy.
Methods: A literature search was conducted on nine databases: Web of Science®, PubMed®, Science Direct, Scopus®, Proquest, MEDLINE®, SPORTDiscus, and CINAHL on articles from inception to November 2021. Mendeley, Endnote and Rayyan were used for data management and screening. The methodological quality of all included studies was critically appraised using Brink and Louw Critical Appraisal Tool (CAT).
Results: Overall, 28 studies were included in the study. 17 articles assessed both validity and reliability, 10 assessed only reliability, and 1 assessed only validity. The apps were categorized into: apps for range of motion, balance, postural, sit-to-stand, and gait. Out of 28 studies, quality assessment scores show only 4 articles were considered poor quality, while 24 were considered good.
Discussion: A number of studies have demonstrated that mobile applications are valid and reliable for joint range of motion assessment, functional activity (i.e., sit to stand) and postural assessment. However, there was a wide range of results from mobile apps for measuring balance and gait; further research regarding their psychometric properties is needed.

Published: May 2023

Introduction: This study aims to determine how the motivational profile affects the behavior change of fitness application users in terms of adopting regular physical activity.
Methods: The study utilized a descriptive correlation method design to determine the variations of the motivational regulations of fitness application users. A total of 204 college students were respondents, wherein 57 were male, and 147 were female. Respondents were of legal age, undergraduates, and have used or are using physical fitness applications. Respondents answered the questionnaire online in their free time. Data collected were subjected to tabulation, averaging, and Fisher’s Exact Test.
Results: The study found no noticeable difference between genders in terms of the motivational regulations comprising their motivational profile and the distribution of users along the stages of the Transtheoretical Model of Behavior Change. Intrinsic and identified regulations were found to be high amongst the respondents (Intrinsic = 5.62; Identified = 5.31), while their external regulation was low (External = 2.51). Data suggest that the motivational profile of fitness application users is found to be autonomous. Moreover, there is a highly significant relationship between identified regulation and exercise behavior change along the preparation or action stages (p = 0.001). A significant relationship between intrinsic regulation and the preparation or action stage of exercise behavior change is also established (Fisher’s Exact Test, p = 0.016).
Discussion: The motivational profiles of fitness application users are favorable in adopting regular physical activity. Promotion and encouragement of the established autonomous motivational profile can help people seriously consider starting exercise as it increases one’s likelihood of sustaining interest and motivation to achieve and maintain higher stages of exercise behavior.

Introduction: The study aims to determine the musculoskeletal side effects after the administration of homologous or heterologous COVID-19 Booster Shot.
Methods: Quantitative descriptive survey design was used through an online questionnaire-checklist on a total enumeration of 313 participants. Frequency distribution on identified musculoskeletal side effects and Chi-square test was used to compare the proportion of respondents and booster shot combinations on the musculoskeletal side effects experienced after booster shot inoculation.
Results: Study revealed 243 (77.6%) females, and 70 (22.4%) males received COVID-19 booster shots; 186 (59.4%) acquired homologous vaccines and 127 (40.6%) had heterologous vaccines. Difficulty raising the arm (M = 83.1%), numbness on the injection site (M = 66.1%), and fatigue (M = 47.9%) were the leading musculoskeletal side effects reported. There is a significant difference (p = 0.048) in difficulty of walking between the sexes, with males experiencing this side effect more (7.1%) than females (2.1%). There is no significant difference in the musculoskeletal side effects for respondents who opt for homologous or heterologous COVID-19 booster combinations, p> 0.05.
Discussion: Musculoskeletal side effects such as difficulty raising the arm, numbness on or around the injection site, and fatigue following the administration of COVID-19 Booster shot are normal regardless of booster combination. Hence, health education on expected musculoskeletal side effects must be given to the public. Application of ice packs on the injection site and mild arm movement exercises to decrease the musculoskeletal discomforts from booster shots may be advised to future vaccine recipients.
Edición ampliada acerca de segundas audiencias de las Cartas Paulinas

El artículo amplía lo ya publicado en F. Bianchini - S. Romanello (ed.), Non mi vergogno del Vangelo, potenza di Dio. Studi in onore di Jean-Noël Aletti SJ, nel suo 70° compleanno (AnBib 200; Roma 2012). Examina la hipótesis de que el apóstol Pablo pudiera tener presente la posibilidad, y quizás la conveniencia, de que otras audiencias leyeran las cartas dirigidas a sus destinatarios primarios. A tal fin, se estudian indicios de la correspondencia paulina, estrategias retóricas, datos contextuales y testimonios epistolares antiguos que hacen plausible la hipótesis. Finalmente, se reflexiona sobre el modo en que las segundas audiencias pudieron leer las cartas como «comunicación comunicada».

„Die ersten Geräusche, die man in Bachmut hört, – das sind anhaltende, dröhnende Echos von Schüssen und Explosionen, die aus verschiedenen Richtungen kommen. Manchmal hören diese Geräusche auf, aber die darauffolgende Stille wirkt nicht weniger bedrohlich. Du machst einen Schritt und weißt nicht, was als nächstes passieren wird. Du verstehst nur: Du bist völlig verwundbar und nur einen Augenblick vom Tod entfernt. Oder ein paar Zentimeter. Das Gefühl einer nicht greifbaren Gefahr, die ganz in der Nähe lauert, lässt nicht eine Minute nach. Du bist ständigem psychischen Druck ausgesetzt. Hier ist es schwierig, einen vom Krieg unberührten Ort zu finden, und jeder einfache Gang auf die Straße kann der letzte im Leben gewesen sein. Jeden Tag sterben Menschen in dieser Stadt.“ … so beschreibt die Fotografin und Journalistin Victoria Ivleva die Eindrücke ihrer Reise nach Bachmut. Die Ausstellung „Bachmut in Bochum“ umfasst 25 Schwarzweiß-Fotografien, die in der ersten Februarhälfte 2023 aufgenommen wurden. Mit Texten im Katalog berichtet Ivleva über das Erlebte.

Authors: C.M.T.Karthigeyan  , C.Satheesh Pandian
Published: May 2023

Wireless sensor networks have wide range of applications. The major constraint in such application lies in the limitation of energy resource. The sensors are often equipped with tiny and irreplaceable batteries. It arise the need of energy efficient routing algorithms to prolong the network lifetime. This project mainly focuses on sleep scheduling for geographic routing in duty-cycled WSNs with mobile sensors by using geographic-distance-based connected-k neighborhood (GCKN) sleep scheduling algorithms. It ensures that coverage rotates such every purpose within the surroundings is perceived at intervals some default interval of your time, referred to as the detection delay. The structure is optimized for rare event detection and permits favorable compromises to be achieved between event detection delays and eventual coverage for every purpose. The cluster activation protocol makes sure that the foremost potential clusters activated to perform target pursuit, reducing consumed energy throughout the hand-off operation. The experimental results show that when there are mobile sensors, geographic routing can achieve much shorter average lengths for all paths using GCKN sleep scheduling compared with those in WSNs employing CKN and GSS sleep scheduling.

História, literatura e emoções
Authors: Silva de Lima Edson
Published: May 2023

Em Poetic Justice, Martha Nussbaum nos permitiu perceber que o espaço imaginativo comporta modelos de realidade que nos convidam a conhecer a nós mesmos pela experiência dos Outros. A literatura, nesse sentido, permitirnos-ia experimentar de outra forma a vitalidade, os impulsos, os entusiasmos, a época e, por conseguinte, a experiência histórica. Assim, seja como condição possível de observação ou como possibilidade de experimentação emocional, a ficção carrega consigo essas experiências particulares partilhadas de maneira especulativa, criativa e imaginativa. Nesse sentido, a metodologia que ampara esse ensaio é a hermenêutica fenomenológica de Paul Ricoeur. Nosso objetivo é discutir a condição de acesso a um modelo de passado possível que congratule ficção, história e emoções a partir da relação estabelecida entre imaginação literária e imaginação histórica.

An Appraisal of Students’ Metacognitive Strategies and Learning: The Case of Undergraduate Educational Psychology Students of the University of Bamenda
Authors: Roland Nji Dr. Angu
Published: May 2023

Purpose: This study aimed at investigating the role metacognitive strategies on students’ learning. In this regard the researcher sought to provide answers to two important research questions namely: 1) How does planning influence students’ learning? 2) How does self-monitoring influence students’ learning? The theoretical underpinnings of the study were provided by Tchombe’s Mediated Mutual Reciprocity Theory, Vygotsky’s Theory of Sociocultural Development, Piaget’s Cognitive Theory of Development Bruner’s Spiral Curriculum. 

Methodology: A descriptive survey design was considered necessary whereby self-constructed close ended questionnaires in a four-point Likert scale format were given to 60 students randomly selected from the Department of Educational Psychology of The University of Bamenda. Data were analyzed by using simple frequencies and percentages.

Findings: Findings of the study revealed that when students engage in planning and self-monitoring, they are better equipped to solve problems and to be better learners who learn in meaningful ways and are able to construct knowledge.

Recommendations: Recommendations were made to educational authorities, teachers and students. For educational authorities, it was recommended that they should closely monitor the teaching and learning process to ensure that learners are not passive observers in the classrooms but are actively engaged in the teaching and learning process. As for teachers, they should help learners to become lifelong learners by teaching the learners metacognitive strategies. Learners should also understand that learning should be about setting goals, planning and self-monitoring and learning must be meaningful.
