Abstract Wild animals and domestic dogs living in human dwellings near forested areas can share ectoparasites, including ticks. In this study, we surveyed ticks associated with dogs which tutors living in the Palmares Environmental Protection Area (EPA Palmares). Dogs were classified into three categories, domiciled, semi-domiciled and wandering dogs according to dog care/ type of dwelling. Ticks were collected monthly from January to December, 2020. Overall, 60 (33.9%) out of 177 examined dogs were infested by ticks. Six species of ticks were identified: Rhipicephalus linnaei, Amblyomma aureolatum, Amblyomma sculptum, Amblyomma ovale, Amblyomma dubitatum and Rhipicephalus microplus. The overall prevalence and presence in semi-domicilied+wandering dogs was higher for A. aureolatum than for R. linnaei by the Chi-square statistic tests. A random sample of 50 ticks, collected from 22 different dogs, were processed through molecular analyses. Ticks were submitted to DNA extraction and also by PCR, using specific primers in order to pathogens monitoring. Four males of A. aureolatum yielded DNA sequences (350 bp) that were 100% identical to the type strain of Rickettsia bellii in GenBank (CP000087).

Abstract The Amazon is the largest river basin in the world and it is home to the greatest diversity of freshwater fish in the world. Mesonauta festivus is a cichlid popularly known as flag cichlid, widely distributed throughout South America. The diversity of parasites in fish from the Amazon region is still underestimated, due to the high fishes diversity. The Myxozoa class has a universal distribution, with some specimens being pathogenic to some fish. The aim of this work was to describe a new species of Hoferellus in M. festivus. The fish were collected in the lake region, municipality of Tartarugalzinho, in the state of Amapá, Brazil. The new species was found parasitizing the urinary bladder of M. festivus. Spores were 11.5 ±1.1 (10.4-12.6) µm long and 10.9 ±1 (9.9-11.9) µm wide, and polar capsules were equally sized, measuring 4.9 ±0.5 (4.4-5.4) µm long and 3.4 ±0.9 (2.5-4.3) µm wide, with a pyriform shape, convergent with the apical region of the spore. The polar filament was wound with 5 to 6 turns. Morphological, morphometric, molecular and phylogenetic analysis proved that it is a new species of Hoferellus in the Amazon region.

Abstract This article reports on a golden-billed saltator Saltator aurantiirostris Vieillot, 1817, kept in captivity outside its natural distribution area, in the proximities of the Itatiaia National Park, as a new host for Isospora similisi Coelho, Berto, Neves, Oliveira, Flausino & Lopes, 2013. Additionally, a supplementary molecular identification is provided through the sequencing of three non-overlapping loci of mitochondrial DNA and one locus of the 18S small subunit ribosomal RNA (18S) gene. All the taxonomic features of the I. similisi oocysts shed by S. aurantiirostris were equivalent to those originally described from Saltator similis d’Orbigny & Lafresnaye, 1837. The new sequenced loci were identical, or showed 99.9% similarity, to the samples of I. similisi from S. similis and S. aurantiirostris, confirming the same species from both hosts. Lastly, I. similisi is estimated as a junior synonym of Isospora formarum McQuistion & Capparella, 1992, due to the morphological similarities and wide distribution of its hosts in the Neotropical region. Therefore, this study encourages future taxonomic inquiries into I. similisi collected from other Saltator spp. in order to establish this synonymization of I. formarum with I. similisi, and hence, its wide distribution and dispersion in the Neotropical region, including across the Andes mountains.

Abstract Babesiosis and Anaplasmosis are diseases associated with economic losses; ticks and blood-sucking flies are important zoonotic vectors and reservoirs. This study aimed to investigate the presence of anti-Babesia spp. and anti-Anaplasma marginale antibodies using enzyme-linked immunosorbent assay (ELISA), in ruminants at the Catimbau National Park. Blood samples were collected from 119 sheep, 119 goats, and 47 cattle. Rhipicephalus microplus ticks were collected from cattle. ELISA showed seropositivity of 34% (16/47), 20.3% (24/119), and 16% (19/119) for anti-Babesia bovis; 34% (16/47), 15.2% (18/119), and 9% (7/119) for anti-Babesia bigemina; and 34% (16/47), 35.6% (42/119), and 17% (20/119) for anti-A. marginale antibodies in cattle, goats, and sheep, respectively. The information collected using an epidemiological questionnaire showed that mostly are breed in a semi-intensive system, with access to Caatinga vegetation. The circulation of B. bovis, B. bigemina, and A. marginale was confirmed. Thus, based on the prevalence, this suggests this is an enzootic instability area and is prone to outbreaks.

Published: October 2024

Abstract This study provides the first report of metazoan parasites in Crenicichla strigata. From 31 hosts caught in the Jari River basin, in the eastern Amazon region of Brazil, a total of 1454 parasites were collected: Sciadicleithrum araguariensis, Sciadicleithrum joanae, Sciadicleithrum satanopercae, Posthodiplostomum sp., Genarchella genarchella, Contracaecum sp., Spirocamallanus peraccuratus, Acarina gen. sp. and Dolops geayi. However, the community was dominated by the three species of Sciadicleithrum (Monogenea) and there was similar presence of parasites in the larval and adult stages. The total prevalence was 100% and each of the hosts was parasitized by two or three species, which presented random dispersion. Brillouin diversity, parasite species richness, Berger-Parker dominance index and evenness were low. There was positive correlation between the abundance of Posthodiplostomum sp. the hosts’ length, while the abundance of S. peraccuratus showed negative correlation with the body weight of fish. The abundance of S. araguariensis, S. joanae and S. satanopercae showed negative correlation with the hosts’ length. The parasite community of C. strigata was characterized by low diversity, low richness, low intensity and low abundance of species.
The Use of Plant Products in Cancer Chemotherapy
Authors: Michael U Adikwu
Published: October 2024

Plants have been used since the existence of man for food. Plants and plant products are easily biodegradable, unlike synthetic products. In Nigeria, people have been dependent on plant materials largely for food and drugs. Thus, many people lived very long and it was common to see people who lived over 90 years in the past twenty to thirty years, up till the 1970s. In the past era, many plant extracts and fractions were used in the treatment of various diseases including various forms of cancers. In the present era, plants and their products have been jettisoned in the treatment of diseases and as food. This has led to early death in many Nigerian communities and diseases such as cancer are on the increase. This mini-review highlights some plant products that are being tested for use and those that are already in use for cancer chemotherapy.
Considerations for Exploring Nanosecond Pulsed Electric Fields (nsPEFs) for Treatments of Cancer, Benign Skin Diseases, Atrial Fibrillation, and for New Mechanistic Understandings
Authors: Stephen J Beebe
Published: October 2024

Pulsed power includes acquiring electrical energy, compressing it, and releasing it in instantaneous bursts that are low in energy but very high in power. When the pulse duration is near the plasma membrane charging time constant, which is the time during which the cell interior is exposed to the applied pulsed electric field, it affects intracellular structures and functions. The technology is called nanosecond Pulsed Electric Fields (nsPEFs), nanosecond electric pulses (nsEP), or Nanopulse Stimulation (NPSTM) according to Pulse Biosciences, Inc., a company taking the technology to the market. Initial studies showed the elimination of tumor cells in vitro by apoptosis, and other regulated cell death mechanisms, elimination of rodent and canine osteosarcoma, and a basal cell carcinoma clinical trial. In the rat liver and mouse breast cancers, tumor-free animals were in situ vaccinated (ISV), preventing the recurrence of the treated cancers. The technology has also focused on treating benign skin diseases, with some advantages over cryoablation. More recently, the same technology called nanosecond pulsed-field ablation (nsPFA) has been used to treat cardiac arrhythmias like Atrial Fabulation (AFib) with catheters in humans. In pre-clinical studies and now in humans, this technology is showing advantages over radiofrequency ablation and cryoablation. On a new mechanistic landscape, nonlethal nsPEFs modulation of electron transport in the plasma membrane and the mitochondria show potential for controlling redox homeostasis and metabolism. Furthermore, different nsPEF waveforms have different effects on cells; waveforms can differ by pulse duration, rise time, electric field, and/or post-pulse features. So, for nsPEFs, there is a lethal side used for ablation as with NPS and nsPFA and a more recently recognized nonlethal side indicating new possibilities to differentially modify cell physiology depending on the different nsPEF waveforms.

This standard operating procedure indicates how to perform data analysis, quality control checks, and data reporting for DDNS and provides guidance on best practice for ensuring relevant sequencing run data are recorded. The document is structured into quality control steps after a DDNS sequencing run. Procedure For DDNS results to be valid and suitable for reporting, sufficient sample metadata must be recorded and data integrity maintained throughout the planning stage of the experiment, during the experiment and after the experiment. Quality control checks have been included to ensure that the protocol has been performed correctly and that results are valid. Later comparison of the DDNS results with culture-based poliovirus detections can be facilitated by adding further metadata describing the timelines and results for processing of the same samples by cell-culture. An overview of the procedure is shown in Figure 1. It is the responsibility of the Lab senior scientist to designate staff to conduct the QC analysis report and to ensure that the personnel conducting the data analysis has provided complete and accurate data, and the report generated is correct prior to approval. Data must be reviewed and approved by the lab senior scientist before QC analysis review with the technical team (PSC member). Designated, technical team lead then submit the QC’d data to the GSL for review/approval. Once approved, the GSL share the QC'd data to the program. A log should be kept of the sequencing runs that are performed, indicating whether all quality control checks have been completed or whether some remain pending, and confirming that all reportable sequences have been reported. All VP1 poliovirus sequences generated by DDNS (even in cases of sample or run QC fail) should be collected into a laboratory sequence QC database folder to aid in the identification of contamination. This addition can be performed by annotating the vp1_sequence.fasta from a run with the run name (e.g. "vp1_sequences_Run21.fasta") and copying it into the database folder. We recommend that if you are using this protocol for stool surveillance, do not add RNA from cell-culture isolates to the same run. The RNA from cell-culture will be hugely more concentrated resulting in the sequencing data skewing towards these samples rather than the stool samples.

Published: October 2024

Extensive research into platinum-based chemotherapeutics has been underway for decades with ruthenium-based complexes emerging as interesting and potent candidates. Even still, there is no evidence of a single mechanism of action across all synthesized and tested Ru-based complexes, prompting the continuance of research in this field. In addition, the mechanism of action varies according to cell line and/or animal model and is seemingly highly individualized and personalized. In accordance with this, the ruthenium complexes are able to activate specific molecular pathways and interact with certain targets within the cell, sometimes reported simultaneously. In this review, we attempt to give a new perspective on ruthenium complexes’ anti-cancer properties and organize selected results from the past 15 years of research connecting their structure with the reported mechanism of action. These results corroborate the previously reported great potential that ruthenium complexes have on cancer in vitro. In addition, the review provides insight into Ru drugs in their clinical trials and their efficacy against cancer including a historical context on metallodrugs, particularly platinum-based complexes, and their antitumor capability.
Fact-Checking Role Performances and Problematic Covid-19 Vaccine Content in Latin America and Sub-Saharan Africa

Published: October 2024

The move from political fact-checking to a “public health” or debunking model of fact-checking, sustained by policies and funding from platforms, highlights important tensions in the case of Covid-19. Building on findings from studies focused on journalistic role performance, we investigated how professional fact-checkers in Latin America and sub-Saharan Africa conceived of and performed their professional roles when addressing Covid-19 vaccination topics. Interviews with fact-checkers from six well-established, Meta-affiliated, International Fact-Checking Network-accredited organizations operating in these regions indicated that fact-checkers recognized the diversification of tasks and new roles associated with addressing problematic content from social media users. However, fact-checkers expressed unanimous commitment to prioritizing political and media watchdog activities in response to problematic Covid-19 vaccine information spreading from elite sources. To compare these role conceptions with role performance, we conducted a content analysis of Covid-19 vaccine content posted in 2021 to these fact-checkers’ Facebook accounts. We found that content was mostly associated with explainers or debunking content (addressing hoaxes or rumors about Covid-19 vaccines from non-elite social media users). In particular, the abundance of explainers, compared with other genres of fact-checking content, aligns fact-checkers with professional roles as civic service providers, educators, and “interpreters” of health information. Only a small proportion of the Covid-19 vaccine-related posts from each fact-checker contained verifications of claims from authoritative (elite “top-down”) sources (i.e., politicians, media, and health/science professionals). This study offers insights into a particularly tumultuous time of political activity in these regions and considers implications for practice innovation.
Anatomical and physiological aspects of the mutual influence of circulatory hypoxia of the myometrium and non-progressive labour
Authors: Sudakov Dmitry S. , Nikolaenkov Igor P. , Dymarskaya Yulia R. , Kuznetsova Anna A.
Published: October 2024

Non-progressive labour occurs in almost 10% of deliveries and is a main reason for unplanned cesarean sections and operative vaginal births using obstetric forceps or vacuum extraction. This article describes the morphological transformation of the myometrium and uterine blood vessels that occurs during pregnancy. It is shown that the myometrium inevitably experiences hypoxia at the microstructural level during each normal or pathological labour. We analyzed recent studies of the mutual influence of myometrial hypoxia and labour dystocia. Experimental and clinical studies showed relationship between the pH values and lactate levels determined in the myometrium on its contractility. Further research is justified, including the study of the pH and lactate values in amniotic fluid in patients with non-progressive labor. Finally, that will allow for clarifying the conditions and timing of labour stimulation with oxytocin and identifying a group of patients for whom oxytocin administration is contraindicated or hopeless.
Pelvic floor status during pregnancy as a predictor of pelvic dysfunction and birth outcome
Authors: Bezmenko Aleksandr A. , Staroverova Anna S.
Published: October 2024

This literature review presents an analysis of a number of studies that examined the association between pelvic floor health during pregnancy and the development of pelvic dysfunction and birth outcomes. These studies consistently demonstrated that changes in pelvic floor structure and function during pregnancy are associated with an increased risk of developing pelvic disorders such as urinary incontinence and pelvic organ prolapse. Besides, certain pelvic floor characteristics, such as muscle strength, tone, and stretching ability, have been identified as potential predictors of pelvic floor dysfunction during pregnancy and prolonged second-stage labor. The data collected suggest that pelvic floor assessment during pregnancy may provide valuable prognostic information about birth outcomes. Understanding these relationships may lead to improved prenatal care strategies and interventions to optimize pelvic floor function and reduce the incidence of adverse birth outcomes. Further research is required to clarify the specific parameters for evaluating pelvic floor changes that are most indicative of pelvic organ dysfunction and adverse birth outcomes, as well as to assess the efficacy of preventive interventions.
Breastfeeding in the prevention of long-term consequences of neuropsychiatric pathology in offspring with gestational diabetes mellitus
Authors: Evsyukova Inna I.
Published: October 2024

This literature review summarizes modern concepts of gestational diabetes mellitus as an independent risk factor for the development of long-term neuropsychiatric diseases in offspring and the mechanisms of their programming in this complication of pregnancy in the absence of the protective role of maternal melatonin as a consequence of chronodestruction. The article presents literature data on the composition of breast milk and the participation of its endogenous melatonin, microRNAs, long non-coding RNAs, stem cells, and microbiome in reprogramming epigenetic disorders as a result of adverse effects in the antenatal period, which helps to reduce the likelihood of developing neuropsychiatric pathology later in life. It is emphasized that breastfeeding during the first six months of life and later, along with complementary foods under the age of two years and older, is exclusively a physiological and unsurpassed method of preventing long-term consequences of impaired brain development in offspring with gestational diabetes mellitus.
The Music of Matrescence: The Missing Link in our understanding of Mother-Infant Bonding through Interactive Music. A Commentary on Vazquez-Diaz de Leon (2024)
Authors: McLean Elizabeth
Published: October 2024

Vazquez-Diaz de Leon’s (2024) study explores mothers’ uses of music in everyday life, illuminating the potential of this reciprocal process in supporting the quality of mother–infant interactions and maternal bonding, while also supporting maternal identity, regulation and coping during motherhood. This commentary calls for further matricentric focused research that acknowledges the social and cultural context of ‘matrescence’ as a significant and transformation shift into motherhood that is largely underrepresented and warrants further exploration and discourse into how this period may intersect with mothers’ musical engagement in everyday life.
Commentary on “Embodiment Consciousness in Music Performance Pedagogy” by Alves and Nogueira
Authors: Bishop Laura
Published: October 2024

This commentary on Alves and Nogueira (2024) proposes a potential approach to compare expert and non-expert music teachers’ use of embodied teaching strategies in one-to-one lessons with advanced performance students. The approach is hypothesis-driven, and builds on Alves and Nogueira’s theoretical framework of expert competency domains, as well as empirical studies of musical communication and one-to-one teaching strategies. It is argued that a comprehensive definition of embodied teaching strategies should be conceptualized in terms of the quality of teacher–student interactions and the measurable outcomes of those interactions, and that it should account for the wide range of verbal and non-verbal forms of embodied musical communication that arise.
Interdisciplinary and Relational Approaches to Embodiment Conscious Music Performance Pedagogy
Authors: Heisel Erin
Published: October 2024

In this commentary on the fascinating study completed by Anderson César Alves and Marcos Nogueira, I discuss two avenues for considering the complexities of embodiment conscious music performance pedagogy. In the first, I contend that music, including but not limited to, music performance pedagogy, is inherently interdisciplinary. In the second, I offer that music performance pedagogy, in particular “studio” or one-on-one pedagogy, is necessarily relational. It is my hope to add value to Alves and Nogueira’s work, while also broadening the lens through which we observe the competencies of both teacher and student within the private lesson context. I close with suggestions for future studies, continuing the important conversation around exceptional teaching and learning for musicians.

Analyzing Common Trade Risks Faced by Tanzanian Traders in International Transactions: A Case Study of Dar es Salaam Importers and Exporters
Authors: Mtolera Oscar , Mwendapole Msabaha , Mugisha Edrick
Published: October 2024

International trade is fraught with inherent risks that can significantly impact the efficiency and success of cross-border transactions. Tanzanian importers and exporters, particularly those navigating the complexities of the Dar es Salaam port, face challenges such as shipment delays, vague contract terms, and financial disputes. This study delves into how the strategic application of International Commercial Terms (Incoterms) serves as a powerful risk management tool, offering clarity and structure to international trade agreements. Utilizing a descriptive research design, we surveyed 96 traders and conducted in-depth interviews to capture their experiences with trade risks and their understanding of Incoterms. The findings reveal a widespread gap in formal training on Incoterms, leading to frequent logistical issues and contractual ambiguities that could otherwise be mitigated. This research highlights the urgent need for targeted educational programs to enhance traders’ knowledge of Incoterms and improve the overall efficiency of Tanzania’s trade environment. By embracing these standardized terms, Tanzanian traders can transform risks into opportunities, positioning themselves as key players in the global trade ecosystem. The study concludes with actionable strategies for improving Incoterm adoption and presents a roadmap for strengthening Tanzania’s competitive edge in international commerce.

Analog One-Cycle Control Strategy for Stable Battery Charging in Photovoltaic Systems
Authors: Neto João T. de Carvalho , Salazar Andrés O.
Published: October 2024

The growing adoption of photovoltaic systems for direct electricity generation from solar radiation has underscored the importance of efficient energy storage solutions. Batteries are the predominant method for storing energy from photovoltaic systems, especially for applications such as electric vehicle (EV) charging. However, these systems face significant challenges, particularly regarding battery longevity, as fluctuations in solar irradiation can lead to harmful voltage spikes. This paper introduces an Analog One-Cycle Control (OCC) strategy designed to mitigate these issues by stabilizing the battery voltage against varying input voltages. The proposed control scheme aims to enhance battery life by preventing damage caused by voltage overshoots. Experimental results demonstrate the effectiveness of the OCC strategy in maintaining steady-state conditions and optimizing power management.
Initial Witnessing on Future Witnessing: A Mediation Analysis of Chronic Community Violence, Posttraumatic Stress, and Delinquency in Urban, African American Youth
Authors: Wilkins Kaleigh , Richards Maryse
Published: October 2024

Witnessing community violence can predict negative mental health outcomes for youth such as posttraumatic stress symptoms and delinquent behavior. Such outcomes differ by gender. Variables that predict witnessing community violence in youth are less understood. This study aims to explore potential pathways between initial witnessing and continued witnessing for early adolescents. The relationship between witnessing as a predictor and witnessing as an outcome is hypothesized to be mediated by both posttraumatic stress and delinquency and moderated by gender. A sample of 153 African American, sixth-grade students (M= 11.65, 59% female) in high-crime, high-poverty areas completed self-report surveys at baseline, 12 months, and 24 months. Moderated serial mediation was used to assess longitudinal associations. For the full model, delinquency at Time 3 was associated with a positive change in witnessing at Time 3. Gender moderated several paths. For girls, witnessing at Time 1 was predictive of high posttraumatic stress (aggregate) at Time 2 and high delinquency at Time 3. For girls, witnessing at Time 1 also was predictive of higherhyperarousal and higherintrusionsubscale symptoms than other symptoms at Time 2. Analyses also indicated thathyperarousalat Time 2 significantly predicted witnessing at Time 3 for girls only. Finally, delinquency at Time 3 was associated with a positive change in witnessing at Time 3. For boys, no analyses indicated witnessing at Time 1 as a significant predictor. Results contribute to our understanding of the trajectory of witnessing community violence and the roles both posttraumatic stress subscales and delinquency play in that trajectory, especially among girls.

This study aims to determine the improvement of physics learning outcomes using a problem-based learning model assisted by PhET simulation media on effort and energy material. This type of research uses a quantitative approach with the Pre-Experimental Design method in the form of One-Group Pretest-Posttest. The population of this study comprised all students of class XI MIPA at SMAN 2 Samarinda, totaling 108 students, while the sample consisted of 36 students from class XI MIPA A at SMAN 2 Samarinda. Data collection was carried out using test techniques consisting of 10 essay questions given before and after treatment. This study used the N-Gain test as a statistical test. The results showed that the average pretest score was 11.33 and the average posttest score was 75.61. The category of improvement in student learning outcomes is classified as high based on the average N-Gain score of 0.73. These results indicate an increase in student learning outcomes after the treatment. Therefore, the implementation of a problem-based learning model assisted by PhET simulation can be used as an alternative to improve physics learning outcomes.

Abstract
The research is motivated by the shortcomings in the use of video tracker applications to measure the height of the marble bounce where the camera used to record the marble bounce must have a certain quality so that the video can be analyzed properly by the video tracker application. The purpose of this study is to analyze the effect of the density of marbles on the value of the coefficient of restitution on the collision of marbles with the floor using a smartphone assisted by the Phypox application. This research is an experimental research using graph analysis method. The results showed that marbles with a density of 950 kg/m3 produced a restitution coefficient of 420.1 x 10-3, marbles with a density of 1400 kg/m3 produced a restitution coefficient of 574.4 x 10-3, marbles with a density of 2400 kg/m3 produced a restitution coefficient of 831.7 x 10-3, marbles with a density of 2700 kg/m3 produced a restitution coefficient of 878.1 x 10-3, and marbles with a density of 7600 kg/m3 produced a restitution coefficient of 888.8 x 10-3. Based on the graph analysis, it is concluded that the coefficient of restitution of the impact of the marbles with the floor is getting bigger and closer to the value of 1 if the density of the marbles increases.

Iṣlāḥ of al-Ghazālī’s Ideas and Movements and their Relevance to Contemporary Islamic Preaching
Authors: Azwar Azwar , Usman Abur Hamdi , Noor Umar Muhammad , Abdullah Mohd Farid Ravi
Published: October 2024

This study aims to examine the thoughts, movements of iṣlāḥ (reform) and tajdīd (renewal) of Abū Ḥāmid al-Ghazālī (d. 1111) and their relevance to the contemporary da‘wah. Based on a descriptively qualitative method and socio-historical approaches, this study shows that Al-Ghazālī prioritized self-reform before societal engagement. Al-Ghazālī emphasized Muslims’ mission to spread Islam and reform society. He identified societal issues, attributing the state of society to the knowledge and credibility of Islamic scholars, and advocated for nurturing new scholars, reforming education, reviving moral values, and promoting social justice. Furthermore, his ideas influenced the emergence of leaders like Ṣalāḥ al-Dīn al-Ayyūbī through educational reforms. In the contemporary context, al-Ghazālī’s thought and movement provide an understanding that the current problems of Muslims need to be resolved from a fundamental problem in the form of  “moral reform”. The roles of ‘ulamā’ (scholars) and umarā’ (leaders) are two essential pillars of the ummah (community), and these two aspects must receive necessary attention in Islamic da‘wah.

O presente artigo tem por tema a abordagem referente ao “Preconceito Linguístico nas Aulas de Língua Portuguesa”, com o objetivo de pesquisar o quanto é comum presenciar casos de preconceito com a língua em sala de aula. Com o intuito de mostrar qual a influência da sociedade e o papel da escola a respeito do preconceito linguístico, é necessário constatar que a língua portuguesa não é baseada somente na gramática normativa, há também de se observar que o preconceito linguístico afeta a aprendizagem do estudante. Esse estudo é realizado por uma pesquisa de caráter bibliográfico. Assim sendo, é possível verificar que muitos permanecem presos ao mito de que a língua mais difícil é a mais bonita e a mais correta, e só pessoas estudadas falam esse dialeto.

Authors: Lanari Alfredo
Published: October 2024

Neste artigo, é realizado um estudo exploratório a partir da aplicação de um método capaz de revelar fraquezas, oportunidades e lacunas sobre um determinado tema. Para tanto, oferecemos uma perspectiva geral do modelo teórico que fundamenta a metodologia da pesquisa, bem como a sua descrição. Em seguida, o método é aplicado para examinar um artigo criteriosamente selecionado para identificar e explorar as vulnerabilidades – escolhas explícitas e implícitas do autor decorrentes dos recortes metodológico, teórico e empírico – sobre um estudo da relação entre ciência e comunicação. Os resultados apontam para a existência de problemas intrínsecos significativos na teoria da ciência contemporânea, bem como que o fenômeno empírico da comunicação em si é passível de tornar-se objeto de estudo de uma ciência da comunicação ainda a ser instituída.

This study investigates the impact of mulberry leaf extract on the viability, plasma membrane integrity, and motility of spermatozoa from male white rats (Rattus norvegicus) exposed to e-cigarette smoke. A total of twenty-five male rats were divided into five groups: negative control (NC), positive control (PC), T1, T2, and T3. All groups, except for the NC group, were exposed to e-cigarette smoke. Rats in the T1, T2, and T3 groups received mulberry leaf extract in doses of 100, 200, and 400 mg/kg bw, respectively, while the NC and PC groups were given a placebo of 1% Na-CMC. Both the mulberry leaf extract and the placebo were administered daily, beginning three days prior to the start of e-cigarette smoke exposure, which lasted for 28 days. Results showed that spermatozoa motility, plasma membrane integrity, and viability in the experimental groups were significantly lower than those in the NC group (p <0.05). Conversely, rats in the T1, T2, and T3 groups that received mulberry leaf extract demonstrated significantly greater spermatozoa viability, plasma membrane integrity, and motility compared to the PC group (p <0.05). The T3 group exhibited the most pronounced improvements, with significantly enhanced spermatozoa viability, membrane integrity, and motility (p <0.05) relative to the PC group. These results indicate that mulberry (Morus alba L.) leaf extract enhanced spermatozoa viability, plasma membrane integrity, and motility in white rats (Rattus norvegicus) subjected to e-cigarette smoke.

The purpose of this study was to determine the effect of administering a dose of gonadotropin (PG-600) in cows with persistent corpus luteum (PCL) which were treated with prostaglandin F2 α (PGF2α) and human chorionic gonadotropin (hCG). This study used 20, three-year-old cows diagnosed with PCL, had recently given birth, and were not pregnant. Cows were randomly allocated into groups T0, T1, T2 and T3.  Cows in all groups were injected with PGF2α (25 mg/cow). Simultaneously, cows in groups T1, T2 and T3 were also injected with PG-600 at doses of 100, 150 and 200 IU/cow respectively. PGF2α and PG-600 were injected when PCL was identified. After that, cows showing signs of estrus were injected with hCG (100 IU/cow) and artificially inseminated 12-18 hours after the appearance of signs of estrus. AI was conducted using frozen thawed semen. Sixty days following AI, a pregnancy examination was conducted using USG. Estrus was detected in all treated cows, while the pregnancy rates varied. Compared with other groups, the groups given 100 and 150 IU PG-600 produced higher pregnancy rates. It could be concluded that the combination of 25 mg PGF2α, 150 IU PG-600, and 100 IU hCG was the most effective treatment to produce high pregnancy rates in cows with persistent corpus luteum.
