Authors: Rodriguez Bernardo J. , Aranzazu Diego , Ortiz Laura C.
Published: August 2024

Summary Swine as well as human naturally harbor Helicobacter spp. and frequently develop gastroesophagic ulcer (GEU). Nowadays in Colombia there are no reports of natural colonization or infection by Helicobacter spp. in swine. The aim of this study investigation was to verify the presence of Helicobacter spp. in ulcerated and preulcerated lesion in the gastric mucosa of pigs and to typify to the different stages of the lesion. This research was carried out in 275 ulcerated, 15 erosioned and 15 normal stomachs obtained from Medellin abattoir at the State of Antioquia, Colombia. The analysis of the results was made by using descriptive statistic. A Z test was used to establish differences between proportions with a level of confidence of 95%. This paper report for the first time in Colombia the natural colonization of porcine stomach by Helicobacter spp. and discuss some aspects of the pathogenesis of GEU.

Published: August 2024

Summary
Biopreservatives for a native strain bacteriocin producer were evaluated on fillets of hybrid Cachama. A raw extract of Lactobacillus plantarum LPBM10-bacteriocin was added to fillets of cachama hybrids (Piaractus brachypomus x Colossoma macropomum) vaccum-packed and stored at 30 °C/30 days. The evaluation was performed with three treatments, crude bacteriocin extract, lactic acid and control. The pH values decrease throughout storage period levels 6.20 at the end of the period. The initial value of thiobarbituric acid (TBA) for the fillets was 0.93 mg of malonaldehyde/kg, the highest values in physicochemical and sensory changes were evaluated to cachama hybrid fillets Piaractus brachypomus x  Colossoma macropomum biopreserved with a crude bacteriocin extract produced by  Lactobacillus plantarum LPBM10, vacuum-packed and stored at 30 ºC/30 days. The evaluation of TBA was obtained up the day 10 of storage. For this period the lactic acid treatment reached the highest value and the lower were observed for the control treatment. The analysis of TVB-N showed the best results for bacteriocin treatment and concluded with 19.3 mg TVB-N/100 g. The results of sensory analysis for fresh and cooked cut fillets showed the best acceptability scores for the crude bacteriocin extract treatment.

Authors: Hernández Carlos , Restrepo Rodrigo , Pérez Janeth
Published: August 2024

Summary
A 5-year-old female schnauzer was attended for being lethargic and having vomit in the past two days. The bitch had been in estrous three weeks ago and the owners noticed a vulvar discharge. During the physical examination, fever and left cranial abdominal pain were found and the presence of bladder stones was suspected. During the exploratory laparotomy a renal and a perinephritic abscesses were found, then a nephrectomy were performed. A cistotomy were also performed and struvite bladder stones were removed. The patient recovered successfully and a commercial diet was prescribed to avoid new calculi formation. Histopathological examination confirmed the presence of both renal and perinephritic abscesses, conditions that are uncommon in dogs and in this case were probably related to pyelonephritis and struvite bladder stones.

Published: August 2024

Summary
In pastures with very diverse botanical composition, as is the case of naturalized pastures in Muy Muy (Nicaragua), it is important to know which species are present in the pasture, because they constitutes a part of the diet for the cattle. That floristic composition change in the pastures managed under different grazing conditions. We evaluated cover, floristic composition and type of the arboreal and herbaceous vegetation under two landscape condition (undulating lands and riverbanks), and two animal management systems, during the dry and wet seasons. Three treatments studied were: "vega" (milking cows grazing in the riverbanks), "leche" and "horro" (milking and dry cows, respectively, grazing in undulating lands), each with eight paddocks as replicates. A simple random sampling was done of treatments in 24 units (paddocks). Inventory of species was carried out adapting the methodology described by Jansson used to study cows' selectivity at different spatial scales. Species diversity was greater in the undulating lands than in the riverbanks. In the latter, Panicum maximum grass was the most common species. Botanic composition of herbaceous vegetation in vegas was different to of undulating lands, in dry season (p < 0.01) and wet season. The most frequent specie on the riverbanks was Asia grass (Panicum maximum).

Published: August 2024

Summary Cytology is a controversial diagnostic tool in veterinary medicine. In Colombia there are no studies about its reliability as a diagnostic tool. The porpoise of this study was to compare accuracy of the cytology with respect to histopathology for the diagnosis of mammary, cutaneous and subcutaneous tumors in dogs. We performed an observational analytic study from July to October 2006. In this study 42 biopsies and 35 fine needle aspiration biopsies (FNAB) of canine mammary, cutaneous and subcutaneous tumors were observed. Samples were obtained from four veterinary clinics in Medellin, Colombia. Samples were processed by rutine methods and they were stained with hematoxilin-eosin and Wright- Giemsa stains. Cytology evaluation was performed by a pathologist and the FNAB by cytology students. The FNAB has a high sensibility to determine malignancy (76.47%), a specificity of 93.33%, positive and negative predictive values of 84.38 and 92.86%, respectively. The concordance between the final diagnosis obtained from FNAB and histopathology was 79%. Cytodiagnosis is a reliable tool to determine the malignancy of mammary cutaneous and subcutaneous tumors in dogs in the pathology laboratory of "Universidad de Antioquia".

Published: August 2024

Summary
The degradation of the malathion pesticide by native microorganisms in an agricultural soil was studied in both laboratory and field conditions. The field study was conducted in a specific area in Caldas (municipality located in the south of the valle de Aburrá, department of Antioquia, Colombia) designated for dairy cattle and vegetable crop. Malathion disappearance and the formation of its main metabolite (malaoxon) were quantified utilizing an analytical method that included a soil sample extraction and pesticide and metabolite quantification by gas chromatography. The extraction was conducted by mechanical shaking with ethyl acetate, and the quantification was performed using a chromatographer connected to a micro-electron capture detector with an automatic injection system. Recoveries were 89.4% for malathion and 93.8% for malaoxon. In the laboratory (35 days, 2.50 µg/g of soil), malathion degradation was 81.6%. 51.3% of this value corresponded to microbial degradation, and the rest was due to losses associated with physicochemical processes. Under field conditions (21 days, 1.50 µg/g), an average degradation of 74.8% was obtained.  Counting of soil microorganisms was 6.8 x 105 CFU/g soil.

Summary
This manuscript is an inedited part of my PhD dissertation, based on historical and recent findings on animal models, that was presented as part of the requirements to fulfill the conditions to become a philosophical doctor on Veterinary Sciences at the University of Wisconsin on October of 2003.The current mini-review written on a free-version style, underlines some of the cornerstones of immunology as a science, understood thanks to the use of the Lymphocytic Choriomeningitis virus (LCMV) experimentally and naturally infected mouse model. It should suffice to say that there have been two Nobel prices of Medicine for discoveries made through the employment of this animal model, in order to recognize the right importance to it. In addition, several laboratories, Dr. Salvato´s among them, have also employed the LCMV-infected Rhesus monkey model as a tool to unravel the mysteries of arenaviral hemorrhagic fever, and particularly the physiopathology of Lassa disease in humans. Here I show some of the knowledge generated through the study of both animal infections.

Published: August 2024

Summary
Stromal cells are the most abundant cell population present in decidual tissue; they are involved in key processes during embryo implantation, fetal nutrition and the pregnancy maintenance. Described procedures for stromal cells isolation require the use of many monoclonal antibodies due to contamination with another cell types in the decidua; besides, some markers of stromal cells show variability during the days of gestation. In this study, we standardized a procedure for isolation by enzymatic digestion, density gradient and adherence to plastic. Murine stromal cells were characterized by exclusion of markers that are expressed in macrophages (F4-80), epithelial cells and trophoblast (cytokeratin-7), yielding a 98% of negative cells for these markers that correspond to stromal cells. This isolation procedure permits to obtain stromal cells with less expensive and high efficiency methods that provide a useful cellular model to study the physiology of gestation in different species.

MODEL OF A STRATEGY FOR THE NATIONAL ECONOMY MACROECONOMIC STABILIZATION BASED ON SOCIAL INCLUSION
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, KRASOTA Olena
Published: August 2024

B a c k g r o u n d. The article argues that the issues of macroeconomic stabilization of the national economy are among the most topical in modern economic research. It is specified that the economic, social, geopolitical and other upheavals of the beginning of the 21st century demonstrate the vulnerability of economic systems to internal and external shocks. They require rethinking the current goals and the searching for new tools to achieve the goals. It is emphasized that the macroeconomic stability of the Ukrainian economy is affected by many factors caused by the processes of uncertainty and unpredictability, in particular, the full-scale russian invasion of Ukraine. These factors adjust the current theoretical approaches to managing macroeconomic stability. M e t h o d s. The methodological foundation of the proposed model relies on significant international and domestic documents in the field of strategic planning and economic security (the latter is understood as macroeconomic stabilization). Based on their analysis, the author justifies an approach to developing a model of a strategy for the macroeconomic stabilization of the Ukrainian economy through social inclusion. R e s u l t s. The primary stages of developing a model of macroeconomic stabilization strategy based on social inclusion are identified, and each stage is enriched with specific content. The author interprets social inclusion and its primary forms of manifestation. A quantitative assessment of social inclusion based on its integral index and aggregated sub-indices of each form of its manifestation is suggested. The article outlines a scope of existing problems that hinder the full use of the potential of social inclusion for the macroeconomic stabilization of the national economy. These issues are related to establishing and normative consolidation of simple, measurable and easily accessible economic and social indicators of social inclusion. These indicators help identify the degree of the macroeconomic stability or instability, determine characteristic values of social inclusion indicators, develop a methodology for their standardization, and establish the appropriate weighting coefficients for each social inclusion indicator. C o n c l u s i o n s. Ensuring inclusive participation of all members of society in social life through non-discriminatory access to income and property distribution, engagement in labor or entrepreneurial activities, and involvement in public governance is a practical approach to accelerating macroeconomic stabilization of the national economy.

The study highlights the importance of export control over dual-use goods (technologies) and its liaison with the economic security of the state. Attention is focused on the necessity of state regulation concerning the export of dual-use goods (technologies) that may pose a potential threat and danger to both the international community as a whole and to Ukraine. Methods. General scientific methods of cognition form the methodological basis of the research . To assess the effectiveness of regulatory acts, the method of analysis and synthesis was used. To identify further directions for improving the domestic institutional environment of export control for dual-use goods (technologies), the research applied a comparative approach by analyzing existing best practices and the national experience of Ukraine. The institutional approach is the basic method to studying the state and potential of the regulatory environment in Ukraine in the field of export control. Its application allowed for comprehensive examination of the research object in the context of ensuring economic security. Results. The effectiveness of the institutional component of export control regulations for dual-use goods (technologies) in Ukraine's economic security system has been analyzed. Conclusions. The paper examines the status of normative legal acts and the implementation of international agreements in controlling the movement and use of dual-use goods (technologies). Proposed directions for improving the Ukrainian institutional environment of export control over dual-use goods (technologies) include: enhancing the normative legal base, coordinating activities of state bodies, establishing clear criteria for evaluating license applications, verifying end-user and end-use verification, to prevent diversion and misuse, etc.

Authors: Fu Zheng , Wahab Nooraskinah Abdul
Published: August 2024

The in-depth development of "Internet +" has made the application of data information technology in ESG (Environmental, Social and Governance) management more extensive and has made the optimization of ESG management the focus of listed companies. The original statistical evaluation method cannot solve the problem of improving the level of ESG management, and the ability to improve the quality of the environment, society and the company is weak, increasing ESG management's difficulty. Therefore, this paper proposes a method based on big data technology to optimize ESG management. First, the "Internet +" technology is used to analyze environmental, social and company quality data, and ESG management classification is carried out according to the requirements of listed companies. Then, according to the classification results, the "Internet+" technology forms different ESG management sets and iteratively mines different sets to obtain the optimal optimization strategy. After MATLAB testing, the effect of ESG management can be improved based on Internet + technology. The effect improvement rate reaches 92.6%, the ESG management process is improved, the improvement is 25%, and the ESG management time is reduced to 15 seconds, which meets the ESG management needs of listed companies.

As águas sem lado de lá: por uma ética da ficção
Authors: Ielpo Rodrigo
Published: August 2024

No conto “A terceira margem do rio”, de Guimarães Rosa, um homem do interior do Brasil parte em sua canoa para aí permanecer, entre as margens, como a formar, como o título indica, a margem ausente de todas as margens. Em “O livro das ignorãças”, do poeta Manoel de Barros, as águas também parecem apontar para esse lugar sem lugar em que as “águas não têm lado de lá.” Assim, por oposição à “terra firme”, as águas aparecem nos dois autores como desterritorialização dos espaços positivos, incitando-nos a refletir sobre uma ética da ficção em que “aquilo que não havia, acontecia”, como lemos no conto de Rosa. O objetivo deste artigo é analisar essa presença das águas nos textos indicados enquanto marca de construção de um regime ficcional em que a dicotomia entre as categorias de verdade e mentira dariam lugar às potências do falso como princípio poético daquilo que Derrida irá chamar de acontecimento.

Tracking immunization milestones: a community-based survey of child vaccination compliance from birth to one year age in India
Authors: Khan Ayub , Shankar Hari
Published: August 2024

Background: Immunization is a crucial public health intervention that significantly reduces childhood morbidity and mortality. In India, despite the efforts of programs like the universal immunization program (UIP), there remain significant challenges in ensuring timely vaccination. This study investigates the compliance with immunization schedules among children in a rural area of Varanasi, India, from birth to one year of age.
Methods: A prospective cohort study was conducted from November 2022 to February 2024, involving 150 newborns. The participants included infants delivered via both caesarean section (CS) and vaginal delivery. Monthly delivery lists from the community health centre facilitated the identification and random selection of eligible newborns. The study entailed a baseline visit followed by four quarterly follow-ups over one year.
Results: The study revealed significant delays in vaccination timing. Hepatitis B had the highest on-time rate at 99.3%, while rotavirus-1 had the highest delay at 35.5%. Other notable delays included BCG (15.8%) and oral polio vaccine (OPV) birth (25.3%). The on-time rates for subsequent doses of OPV and pentavalent vaccines ranged from 65.9% to 77.7%, with delays observed in about a quarter of the vaccinations. Socio-demographic factors indicated a predominance of joint families (85.3%), with most parents having completed high school or higher education.
Conclusions: The findings highlight the need for enhanced strategies to improve adherence to vaccination schedules in rural areas. Significant delays in immunization, particularly for rota-1 and OPV doses, underscore the necessity for targeted interventions.

El diálogo entre la tradición y la comprensión: una reflexión gadameriana sobre el pasado y su impacto en la interpretación histórica
Authors: Cieri Martín
Published: August 2024

Esta perspectiva examina las ideas de Hans-Georg Gadamer en su obra Verdad y Método, destacando cómo nuestra comprensión del pasado está profundamente influenciada por las tradiciones en las que estamos inmersos. Gadamer desafía las nociones de objetividad y neutralidad en la historia y la ciencia, argumentando que nuestras interpretaciones están inevitablemente teñidas por experiencias, prejuicios y valores personales. Se enfatiza la relación interactiva entre la subjetividad y la objetividad, mostrando cómo la tradición afecta nuestra percepción del pasado y cómo, a su vez, nuestras investigaciones actuales pueden reconfigurar esa misma tradición. Este enfoque hermenéutico invita a una reflexión más profunda sobre cómo la tradición y la comunidad configuran nuestra comprensión del mundo, sugiriendo que la ciencia y la interpretación histórica son procesos dialógicos y contextualmente enraizados en lugar de esfuerzos puramente objetivos.
Modulatory Role of NTSR1 Antagonist SR48692 in HFD-Induced Thyroid Impairment in Mice: An In Vivo Study
Authors: Pal Himanshu , Verma Pradeep , Mohanty Banalata
Published: August 2024

Thyroid hormones are one of the crucial regulators of metabolism, especially lipid, and is linked with lipid metabolism dysregulation. High-Fat Diet (HFD) induces the secretion of Neurotensin (NTS), which enhances lipid absorption, and deposition, proportionately increases leptin. Increased leptin is associated with central leptin resistance and affects thyroid regulation which may lead to hypothyroidism. We hypothesized that HFD-induced increased NTS may cause dyslipidemia leading to thyroid alterations, which could be antagonized by the NTS receptor-1 (NTSR1) antagonist SR48692. Swiss albino mice (n = 24) were divided into two sets and fed with Standard Diet (SD) and HFD for 4 weeks. After that each set of mice were further divided into two groups and administered with 0.9% saline and SR48692 (100 μg/kg bw) intraperitoneally for 4 weeks and maintained as Group-I: (Control/SD), Group-II: (HFD), Group-IV: (HFD+SR48692), and Group-IV: (SD+SR48692). HFD-fed mice showed significantly decreased T3 and T4 with increased TSH and leptin, suggesting leptin-induced hypothyroidism, also reflected in the histological alterations observed in thyroid and adipose tissue. Co-treatment with SR48692 (HFD+SR48692) showed amelioration in the thyroid, as levels of T3, T4, TSH, and resensitization of leptin, were evident in histopathological analysis compared to HFD suggesting the therapeutic efficacy of SR48692 on thyroid impairment in dyslipidemia. Only SR48692-treated group showed an exacerbating effect.

Benz[a]anthracene, a polycyclic aromatic hydrocarbon found in environmental pollutants, poses significant health risks, particularly to the respiratory system. This study aimed to evaluate the potential therapeutic effects of different solvent fractions of Curcuma longa rhizome methanol extracts against benz[a]anthracene-induced pulmonary toxicity using an in vivo rat model. The methanol crude extract of C. longa was partially fractionated using partition chromatography with silica gel as the adsorbent. Four solvent fractions obtained using gradient elution (designated ethanol, ethyl acetate, diethyl ether, and n-hexane fractions) were collected and used in the experiment. Albino Wistar rats (Rattus norvegicus) were randomly divided into seven groups and administered benz[a]anthracene to induce pulmonary toxicity. Subsequently, rats were treated with different solvent fractions of C. longa or diclofenac sodium as a positive control. Body weights were measured weekly, pre-induction, post-induction and post-treatment blood samples were collected, and lung tissue samples were collected and analysed. Treatment with the ethyl acetate fraction of C. longa resulted in significant improvements in lung histopathology compared to benz[a]anthracene-treated rats alone, suggesting potential anti-inflammatory effects. Furthermore, this fraction showed significant antioxidant enzyme activities, including glutathione peroxidase, glutathione reductase, and superoxide dismutase, indicating its ability to mitigate oxidative stress. Biochemical analysis revealed that the ethyl acetate fraction also significantly decreased serum levels of tumour biomarkers, such as epidermal growth factor receptor, cancer antigen 125, and carcinoembryonic antigen, suggesting its potential in inhibiting cancer-related processes induced by benz[a]anthracene exposure. Our findings suggest that the ethyl acetate fraction of C. longa rhizome may hold promise as a therapeutic agent against benz[a]anthracene-induced pulmonary toxicity, possibly through its anti-inflammatory, antioxidant, and anticancer properties. Further research is warranted to elucidate the specific compounds present in this fraction and the underlying mechanisms through which they exert their effects, to optimize their therapeutic potential.
Les mobilisations familiales pour le départ migratoire à partir de la Casamance (Sénégal)
Authors: Ngom Abdoulaye
Published: August 2024

Le rapport entre les salaires de base en Europe occidentale et en Afrique subsaharienne est d’au moins un facteur dix, voire nettement plus ; et il n’évolue guère. Beaucoup de jeunes Africains rêvent donc d’émigrer en Europe. La voie aérienne reste un privilège réservé aux familles des élites : pour prendre l’avion il faut un visa pour un pays européen. Sans visa il ne reste que la voie maritime, par navigation côtière le long des côtes africaines, et la voie terrestre à travers le Sahara. Ce sont ces voies très dangereuses et à l’issue aléatoire qu’empruntent chaque année des dizaines de milliers de migrants. L’article étudie le cas d’une famille de petits paysans-éleveurs vivant d’autosubsistance de l’intérieur de la Casamance, la région du Sud du Sénégal. Il permet de voir comment ce groupe familial de 42 personnes en vient à décider d’envoyer l’un des siens tenter d’entrer clandestinement en France, au risque de sa vie. Comment il choisit le migrant et se mobilise pour réunir les fonds nécessaires ; et ce qu’il advient des deux tentatives. Cette étude de cas donne une idée des étapes suivies chaque année par des dizaines de milliers d’autres familles en Afrique.

The two poems presented here were both written with gratitude for the freedom of expression I enjoy in Canada. “How To Know I Am A Human” is from my new manuscript, A Life Between The Brackets, which addresses several themes and topics I stay close to, including the natural world, climate events such as wildfires and hurricanes, and local and global politics. “The Erosion Of Borders” is from my 2022 collection, A Matter Of Inclusion, which investigates the decisions people make to leave their homelands to begin new lives in Canada. It is my most overtly political work to date.

R. Pound’s Ideas on Legal Proof Patterns and the Modern Era

The theoretical provisions on the laws of legal evidence formulated by the American lawyer, teacher and sociologist of law Roscoe Pound (1870–1964) in the work “The Ideal Element in Law” (1958) are considered. It is substantiated that the theoretical provisions of R. Pound are hardly justified in being considered as limitations of legal regulation; they rather fix a number of objective patterns immanent in the functioning of law as a special normative system, acting only through human activity, which will not lose their significance in the future. They are as follows: a combination in legal proof of the principles of formal and free assessment of evidence; the use in the process of legal proof of legal-factual fictions — irrefutable cognitive constructions, regarding which it is unclear whether they are true or false in a particular case, but accepted as established factual circumstances; the impossibility of establishing the truth in the process of legal proof. It is shown that the requirement to establish the truth in a legal matter (material, objective or any other) obviously goes beyond the limits of cognitive capabilities, and the circumstances to be proven can only be established with varying degrees of reliability, based on the available traces of a legal fact.
Legal Education in Byzantium in the 6th to the 15th Century

In the absence of specialized education for representatives of different professions in Byzantium, legal education was an exception. As early as the 3rd century a law school was opened in Beirut, then in Constantinople (425) and in other cities. Emperor Justinian included “Institutions” in the Corpus Juris Civilis specifically for young people studying law. In the VI–VIII centuries, the professional training of lawyers continued, but there was a crisis in it. Constantine IX Monomakh published a novel about the creation of a law school headed by nomophilax in the middle of the XI century. But it did not last long, and up to the middle of the 15th century lawyers were engaged in independent study of law (αυτοδιδασκαλια), resorting to the help of practicing lawyers. The services of lawyerstabularies were used by the whole population, lawyers became officials, judges, participated in the preparation of laws and their codification. The high level of legal consciousness of the Byzantines led to a growing interest in legal education.

International Relations (University) of the Ministry of Foreign Affairs of the Russian Federation, LL.D., Associate Professor In the context of the development of domestic tourism, there is an urgency to develop facilities in this area, create a favorable infrastructure to increase the number of tourists. In this regard, there are questions of legal regulation of the financing of tourism activities that contribute to its development and transformation. In the course of the research, both general scientific and private scientific methods were used: scientific abstraction, systematic, logical, analysis and synthesis, comparative legal and formal legal. Conclusions are drawn that: 1) there is no legislative provision fixing possible sources of financing for tourism activities; 2) the financial mechanism is represented by budget financing and investment, including crowdfunding; 3) the use of foreign experience allows increasing the volume of budget financing by expanding the practice of introducing a resort fee, but even despite this measure, investment remains the predominant element within the financial mechanism. The scientific and practical significance of the conducted research lies in the fact that it allows us to critically comprehend the existing sources of tourism financing, the specifics of their legal regulation, and also contributes to the development of theoretical directions on this topic and the formation of educational materials devoted to the legal regulation of financing tourist activities.

Hypersomnias (hypersomnolence) are a group of neurological diseases with the main manifestations in the form of pathological daytime sleepiness and/or excessive need for sleep. Most sleep disorders are also accompanied by increased sleepiness during the day, which requires differential diagnosis of various causes of hypersomnia and identification of central hypersomnolence, which are rare diseases. There are difficulties both with the determination of the pathology of drowsiness and the subjective assessment of the duration of sleep. High sleepiness disrupts daytime functioning and reduces performance, the ability to drive a car, and can cause accidents and injuries. Hypersomnia is often comorbid with psychiatric disorders such as bipolar disorder, depression, and seasonal affective disorder. Depressive thoughts, aggressiveness, as well as comorbidity of hypersomnia with hysterical personality disorder are noted. Clinical and psychological aspects of hypersomnia at this stage have not been studied enough. The presented psychological consequences, as a rule, were described from the point of view of doctors’ observation of the behavior of patients, while a targeted study of the psychological characteristics of the personality of patients in most cases was not carried out. In the framework of future research, it seems relevant to study the clinical and psychological characteristics of patients with various forms of hypersomnia and to determine the targets of psychocorrectional work.
