New Criteria on the Oscillatory Behaviour of Second Order Nonlinear Differential Equations with Mixed Neutral Terms
Authors: Grace Said R. , Graef John R. , Kaleeswari S.
Published: December 2023

The authors present some new criteria for the oscillation of second order nonlinear differential equations with mixed nonlinear neutral terms and mixed deviating arguments. The approach used is to linearize the equation under consideration and then to deduce the oscillation from that of the linear form. In so doing, the authors obtain new oscillation criteria via a comparison with the first order equations whose oscillatory behaviors are known. They illustrate their results with some examples.

Authors: Oliveira Catarina Novalio , Braga Diana , Ferreira Nelson , Silva Cláudia , Pino Inês , Santos Filomena
Published: December 2023

Background:

Mycosis fungoides (MF) represents the most common cutaneous T-cell lymphoma and approximately 4% of non-Hodgkin lymphomas. Treatment of skin lesions includes external beam radiation therapy which often provides adequate local control and symptom relief.

Case Presentation:

A 39-year-old male with the diagnosis of MF presents with infiltrative and pruriginous plaques comprising the plantar, interdigital, lateral, and posterior surfaces of the foot. A protocol using a water tank was used to provide uniform coverage to an irregular target volume. By creating a tissue-equivalent and homogenous bolus material a total dose of 8 Gy in two fractions of photon-beam therapy was prescribed. After 1 month of treatment, there was a partial response with minimal toxicity, achieving a complete response in most lesions after 6 months.

Conclusion:

Photon-beam therapy for irregular surfaces such as extremities is a valid alternative to conventional electron-beam radiation by attaining uniform coverage while minimizing hotspots. Treatment utilizing a water tank is well-tolerated and has good clinical outcomes even in the presence of extensive skin lesions.

Objective:
This study aimed to assess the knowledge and awareness of diabetic patients in Saudi Arabia regarding ocular complications, their practice of routine eye examinations, and diabetes management.
Methods:
A descriptive cross-sectional study was conducted among 430 diabetic patients in various regions of Saudi Arabia. An internet-based questionnaire was used to collect data.
Results:
The study revealed that 38.5% diabetic patients had excellent knowledge about ocular complications, 31.4% had average knowledge, 21.4% had poor knowledge, and 8.7% had no knowledge. Diabetic patients demonstrated higher levels of knowledge and better practices for eye exams and diabetes management compared to healthy individuals. Furthermore, a significant association was found between knowledge levels and the diagnosis of diabetic retinopathy. Education level was also correlated with knowledge, with individuals holding master\'s or PhD degrees showing the highest awareness.
Conclusion:
This study highlighted the importance of targeted education and awareness initiatives for diabetic patients, particularly those with lower education levels, to improve their knowledge of ocular complications. Routine eye examinations are crucial for early detection and treatment of ocular problems in diabetic patients. Early diagnosis of diabetic retinopathy is essential for better ocular outcomes. The findings provide valuable insights for healthcare providers and policymakers to enhance diabetes education and awareness programs in Saudi Arabia.

Published: December 2023

Obstructive sleep apnea (OSA) is a progressively sleep-disordered breathing condition marked by bouts of upper airway obstruction during sleep. This systematic review aimed to comprehensively explore the lately available literature on OSA as an independent risk factor for developing hypertension (HTN). PubMed, SCOPUS, Web of Science, Science Direct, and Google Scholar were systematically searched for relevant literature. Rayyan QRCI was employed throughout this comprehensive process. This review included eight studies with a total of 12,473 parents, and 8,974 (71.9%) males. The total frequency of HTN in OSA cases was 5,643 (45.2%). The prevalence of HTN was rather high in OSA patients. Obesity and elevated bicarbonate levels were cofactors in the development of HTN in OSA patients. Children with OSA were three times more likely to develop HTN in the future. A growing number of OSA patients had or required HTN treatment. If treatment is not received, the patient becomes more vulnerable to cardiovascular and cerebrovascular diseases as a result of a self-perpetuating pathophysiological process. Even though there is a lot of research and strategies available for OSA cases who necessitate blood pressure decline, further choices are critically needed.

Published: December 2023

A doença de Alzheimer, um transtorno neurodegenerativo progressivo, caracteriza-se pelo declínio cognitivo e perda de memória. No Brasil, a urgência em desenvolver ferramentas diagnósticas menos invasivas e mais acessíveis para esta doença é evidente. Este estudo objetiva suprir lacunas técnicas na revisão de biomarcadores para Alzheimer e introduzir temas correlatos. A metodologia adotada foi uma revisão sistemática de artigos recentes, com uma seleção criteriosa baseada em palavras-chave relacionadas a biomarcadores para Alzheimer. O estudo compara diferentes métodos de biomarcadores, destacando a importância da escolha adequada para um diagnóstico eficaz. Embora a coleta de líquor ofereça correlação direta com a doença, sua natureza invasiva pode ser uma limitação. A tomografia PET de β-amiloide permite detecção precoce, mas é complexa e envolve radiação. Alternativamente, biomarcadores plasmáticos, como a razão Aβ42/40, emergem como opções menos invasivas e promissoras. Métodos automatizados como o HISCL são eficazes, mas a escolha do método depende de recursos e objetivos diagnósticos. A combinação de biomarcadores pode melhorar significativamente o diagnóstico da doença. Portanto, no contexto brasileiro, a necessidade de desenvolver novas tecnologias diagnósticas é crítica para garantir a detecção mais simples e rápida do Alzheimer, principalmente em suas fases iniciais, proporcionando triagens menos desagradáveis aos pacientes.
EDUCAÇÃO E VERDADE: UMA ANÁLISE EDIPIANA A PARTIR DE MICHEL FOUCAULT
Authors: Lemos Vinícius Cubero Valentim , Silveira Carlos Roberto da , Ribeiro Evandro Luiz Amaral
Published: December 2023

Esta pesquisa de Iniciação Científica possui abordagem qualitativa, teórica e reflexiva. Teve por objetivo desenvolver uma análise sobre uma parte da obra de Michel Foucault, tendo por fundamentação principal, A verdade das formas jurídicas. A obra é composta de cinco conferências que introduzem uma visão Foucaultiana sobre a Verdade. Investiga-se, em especial, a segunda conferência, em que ele desenvolve o mito de Édipo, distante da visão psicanalítica, mas que se aproxima da questão de poder. O ponto de partida deste artigo é sobre a Educação, o saber e a verdade, ou seja, a parrhesía a partir da ideia de paidéia. Desenvolve-se em três seções. A primeira seção trata sobre a paidéia, a educação grega, na qual se atenta para o contraste entre os dois poetas gregos, Homero e Hesíodo, quanto às concepções sobre o caráter e a virtuosidade entre os gregos, ou seja a areté. Contudo, também é tratado a virtude da parrhesía. Na segunda seção, tem-se as técnicas jurídicas gregas, em que se busca a produção da verdade, isso através do desenrolar sobre o mito de Édipo. A terceira seção, possui a abordagem sobre a parrhesía, momento este em que se adentra às outras conferências de Foucault, que foram realizadas na Universidade da Califórnia, em Berkeley. A educação e a verdade naqueles tempos da paidéia eram complementos da areté. Sabe-se que a verdade no Ocidente passou por várias transformações. No entanto, ao longo deste trabalho acredita-se que a parrhesía, possua traços fundantes que podem ser valorativos em nossa contemporaneidade.

Published: December 2023

O potássio (K) é um nutriente essencial para todos os organismos vivos, sendo um macronutriente fundamental para o desenvolvimento das plantas. As rochas que possuem elevados teores de potássio podem ser aproveitadas como fontes alternativas de fertilizantes para aplicação direta no solo, com o objetivo de atender a alta demanda agrícola brasileira, reduzindo assim, a dependência da importação de fertilizantes. Além disso, é sabido que muitos microrganismos presentes no solo têm a capacidade de solubilizar o potássio contido nos minerais. Nesse contexto, o presente estudo buscou avaliar o potencial de bactérias isoladas de um solo tropical, na solubilização do potássio presente em rochas e resíduos de rocha. Foram isoladas 72 estirpes bacterianas, das quais 5 apresentaram potencial para biossolubilização de potássio, a partir do teste de halo. Os ensaios de biossolubilização de potássio in vitro utilizando as estirpes selecionadas foram realizados em meio Aleksandrov, com a adição do pó de rocha como única fonte de potássio no meio. Os resultados mostraram que todas as estirpes bacterianas selecionadas foram capazes de solubilizar o potássio presente nos pós de rocha. Dentre as estirpes testadas, a IA13 se destacou por ter apresentado o maior percentual de extração de potássio em relação ao controle abiótico (259,82% para a Amostra 8, 300% para a Amazonita e 216,13% para o Kamafugito). Dessa forma, as estirpes bacterianas avaliadas neste estudo demonstraram potencial para serem testadas em processos biohidrometalúrgicos. Esses resultados são considerados promissores, frente aos desafios e a complexidade da remoção de potássio por rota biológica.

The concept of "way" as a characteristic of the image of the hero in the novel by A. A. Fadeev "The Rout"
Authors: Yuan Xinjie
Published: December 2023

The subject of the study is the representation of the concept of the "way" in the novel by A. A. Fadeev "The Rout". The purpose of the work is to describe the representations of the concept of "way" as a real space in the novel and as a metaphor for the changes of its characters. The space category reflects the topographical features of the Far East, helping to trace the path of the detachment in the coordinates of space through the point of view of the protagonist. The spatial frame of the narrative is built with the help of specific subject words and toponyms, which mainly represent the remote countryside and the physical geography of the Far East. The attributes that form the natural space in the novel correspond to the negative emotional changes of the characters, revealing the inherent cruelty of the Civil War. When expressing this type of spatial relationship, it is the verb that plays the dominant role, which is based on the separation according to the static/dynamic manifestation of locative semantics, at the same time, verbs of displacement significantly surpass verbs of position. The following methods were used in the course of the study: the method of linguistic description, the method of contextual analysis, and the method of semantic analysis. The text space, as an important part of the content of the novel, depicts fragments of reality, and through the spatial concept of the "way" builds a general spatial picture of the world. The concept of "way" in a metaphorical sense is a subconcept of the concept of "Civil War", in accordance with this, the results of this work enrich the figurative zone of the concept of "Civil War". An analytical algorithm for the study of text space can be applied to the spatial analysis of similar works of art. The result of the study was the conclusion that the "way" is one of the central concepts of the novel. The concept of "way" has a negative connotation, suffering occurs in the process of the detachment's retreat. In addition, A. Fadeev includes spiritual trials in the path of the revolutionary hero, the character completes internal changes in the affirmation of socialist values in external crises and complex character relationships.
"Cold deficiency" and degradation of permafrost soils as a factor of transformation of hunting activity among the Yakuts
Authors: Gogolev Anatolii Ignatevich , Fedorov Sviatoslav Igorevich
Published: December 2023

One of the most important global problems of the XXI century is climate change. Every year, in some parts of the world, a decrease in annual precipitation and temperature is recorded, in others, on the contrary, an increase. These fluctuations can cause droughts, floods and degradation of permafrost soils. Further climate change may cause irreparable damage to traditional farming methods and adversely affect housing conditions in many regions of the globe. Thus, climate change can complicate and disrupt the established order of life and activity of the population of the Republic of Sakha (Yakutia). This paper highlights a problem that has not been specifically studied before, and which concerns all hunters of the republic, the impact of climate change on hunting activities. The work is based on field materials collected by Vilyuysky and Tattinsky districts. Field materials were collected by audio, photo and video recording, in-depth interviewing and included observation during field work in the Vilyuysky and Tattinsky districts of the Republic of Sakha (Yakutia). In earlier scientific works research was conducted separately on the topic of the impact of climate change on the daily life and economic activities of the Yakuts, in this work hunting activity was considered. Hunters who participated in the research adapt to the changing climate in various ways: they increase the range of hunting area, equip trips over longer distances than before, learn to re-read changes in weather conditions, manufacture and use various devices for hunting and storage. The main conclusions of the research are that climatic changes directly or indirectly affect hunting activities in the studied areas: ordinary amateur hunters note that the habitat of animals is changing, roads are being destroyed, the soil of hunting grounds is degrading, there is a danger of the spread of various diseases.
Transformation of winter costume in Yakutia in the era of modernization of the late XIX – mid XX centuries.
Authors: Fedorova Aitalina Rodionovna , Gogolev Anatolii Ignat'evich
Published: December 2023

This article examines the process of changing everyday clothes in Yakutia in the late XIX – mid XX centuries on the example of a winter suit. This historical period was marked by active modernization processes in the region, which also affected the material culture of the population. The issue of adaptation of residents of the Far North to new economic conditions is relevant in this regard: how the transition from the traditional way of life to Soviet culture took place. The hypothesis of the present study is that the culture and technologies of traditional tailoring of fur and leather have been preserved in the studied period precisely because of the need for the population to self-sustain themselves with winter clothing in conditions of shortage of goods and raw materials. The chronological framework of the study covers the period of the end of the existence of the traditional Yakut costume and ends in the middle of the twentieth century. To study the winter costume, photographic materials were used, which depicted samples of everyday clothes. Photos from the photo funds of the Yakut State United Museum of History and Culture of the Peoples of the North named after Em. Yaroslavsky, which includes images from both public and private collections, are considered. In addition, consultations with informants were held to supplement the data. This topic has not yet become the subject of special study, since the costume of this period is no longer ethnic. Nevertheless, in our opinion, it is interesting in the context of studying the adaptation of folk traditions to modernization processes. Using visual and field sources, the transformation of casual clothing in Yakutia of the studied period is considered. The authors of the article came to the conclusion that in the era of modernization there was a sharp change in the way of life, which affected the material culture of the inhabitants of Yakutia. Unification in the wardrobe of citizens of the Soviet state in the first half of the twentieth century could not always cover the needs of residents of specific climatic zones, including residents of the northern republics. This contributed to the preservation of traditional technologies of manual production of winter clothing.
The Content and Function of Cosmopolitanism in a Selection of International Criminal Law Tribunals
Authors: Nell Albert
Published: December 2023

Reasoning and justifications before the international criminal tribunals and courts (ICTs) have not always strictly kept to legal rules and/or legal standards. At times, philosophical structures were used directly in argument. Consequently, this article is, in particular, concerned with cosmopolitanism in arguments and judgments from a selection of counsel and judges emanating from the Nuremberg and Tokyo International Military Tribunals as well as the ad hoc International Criminal Tribunal for the former Yugoslavia (ICTY) and the International Criminal Tribunal for Rwanda (ICTR).  It aims to provide an analysis of how the different generations of ICT and the different role-players therein used cosmopolitanism in their arguments. While not a treatise on cosmopolitanism as such, the article will identify and consider several broad cosmopolitan strands relevant to the selected arguments. The ensuing analysis will propose a taxonomy of specific arguments from the selected role-players addressing (1) the existence of a homogeneous civilisation and/or common morality as a descriptive truth or falsity, (2) the progressive realisation of the international society as a normative aspiration and (3) the relationship of the duty to the international community versus that owed to the domestic community of birth. Thereafter, the article will discuss plausible functions, in addition to persuasion, served by these arguments (including winning the case, undermining or supporting the legitimacy of the ICL proceedings in their entirety and/or controlling the subsequent historical narrative). Finally, the article will situate these investigations within the broader study of philosophy at the selected ICTs.
Restrictions on Freedom of Religion in the Time of National Disaster—Lessons from Mohamed and Others v President of the Republic of South Africa and Others
Authors: Dube Angelo
Published: December 2023

In late 2019, reports of a novel influenza-like virus emerged from China, whose Province of Wuhan was severely affected. It was not until February 2020 that the World Health Organisation was able to give this virus the name Covid-19. At that stage, the world was clearly dealing with a pandemic. Governments worldwide, including the South African government, responded by declaring a state of disaster and imposing restrictions on travelling and public assemblies. After declaring a state of disaster, the government promulgated the lockdown regulations, which prohibited, amongst others, congregating for religious purposes. A group of adherents of the Islamic faith felt aggrieved by these regulations, alleging that they were irrational and unreasonable, to the extent that they unfairly limited their freedom of movement and religion. They launched a constitutional challenge in the High Court in the case of Mohamed and Others v President of the Republic of South Africa and Others. In casu, the court had to deal with the novel issue of the limitation of rights in the context of a pandemic, as well as the rights of religious minorities.
Prospects and Challenges of Extracting Scientific Publications from a Doctoral Thesis in International Economic Law: An Academic Excursion
Authors: Mhlongo Lindelwa Beaulender
Published: December 2023

Africa produces less than one per cent of the total global research outputs. This is despite African institutions having been involved in producing knowledge for millennia. The centres of learning of Alexandria in Egypt, the ancient universities of Timbuktu and the monasteries run by Christian organisations in the third century BC are notable instances of research and knowledge production on the African continent. Today, Africa is lagging behind in knowledge production, including knowledge about Africa and Africans themselves. As a response, African universities, particularly in South Africa, have adopted strategies to increase knowledge production. Amongst the approaches taken is the growing trend to demand co-authorship between supervisors and their supervisees, ensuring that portions of the postgraduate Doctoral research eventually feature as a journal article or a book chapter. The other approach has been for some universities to demand that the student must publish two chapters or one chapter from their thesis before they are permitted to graduate. While both these approaches are commendable, the fact remains that universities are not doing enough to equip these emerging researchers to transition from mere students to published authors in peer-reviewed accredited journals. This article interrogates the challenges and prospects brought about by this academic demand, the causes of some of these challenges, and how students who are registered for international economic law can successfully navigate these barriers. The article draws from the author’s personal experience in converting her Doctoral chapters into published journal articles.

Angelman syndrome: A genetic challenge for physical and learning disabilities
Authors: Alias Bassy Kuruppan , Simon Lini K.
Published: December 2023

Angelman syndrome (AS) was first reported in 1965 by Dr. Harry Angelman. It is a condition of neurodevelopment characterized by, a lack of speech, distinctive behavior, seizure, intellectual capacity, and cheerful disposition. The cause of AS is a lack of production by maternal imprinted genes (UBE3A) on the 15q11-q13 chromosome. The complications of AS are strabismus, atrophy of the optical nerve, and blindness, which are rarely reported. There is a possibility of complications in the laboratory diagnostic tests for AS. One method is to evaluate with DNA methylation analysis of AS/Prader-Willi Syndrome (PWS) imprinting center (IC). On cytogenetic analysis, at least 50–60% of patients had a maternally induced de novo mutation of chromosome 15q11-13 with more serious clinical phenotypes such as microcephaly, seizures, language impairment, and motor difficulties. Multiexonic or whole gene deletion is identified by array-comparative genomic hybridisation (CGH) in some cases and laboratory and methodology may vary such deletions. Diagnosis of AS can be suggested by unsteady movements before walking. Based on the patient’s medical history, electroencephalogram (EEG) data, clinical symptoms, and the presence or absence of a chromosome 50 deletion, a diagnosis of AS is made. Incidence estimated for AS is approximately 1 in 12,000–20,000 birth lives, but the epidemiological measures of life expectancy remains unknown. The clinical features of AS phenotype include seizures, sleep disturbance, intellectual disability, and movement disorders such as tremor and ataxia, anxiety, expressive language is limited, behavioral changes, pleasant demeanor, and easily manipulated laughs, EEG abnormalities were discovered in around 100% of the patients. The researcher identified problems with inflammation at the injection site caused by a higher dose of a drug and they monitored proteins in the individual’s blood and cerebrospinal fluid as an additional safety precaution. Genetic counseling for families with one child with AS to address the likelihood of recurrence can be a challenging subject that frequently requires specialist advice.

To reduce pollution, sulfur, nitrogen, and other heteroatoms are removed from fuels by hydrotreatment (HDT). Conventional HDT catalysts are based on Ni-MoS2 phases dispersed over -Al2O3. Despite the myriad of papers studying these catalysts, it is somehow surprising to learn that the role of Ni in these catalysts is not yet fully understood. Most literature considers that Ni is either converted to some form of catalytically inactive nickel sulfide or that it mixes with MoS2 to act as a strong catalytic promoter. In this work, we focused on analyzing whether well-dispersed supported nickel nanoparticles can be active in the hydrodesulfurization of dibenzothiophene; one of the most refractory molecules composing diesel and marine fuels. We dispersed nickel using the principles of the strong electrostatic adsorption (SEA) method over silica (~neutral acidity), Al2O3 (Lewis acidity), H+-Y zeolite (Brönsted-Lewis acidity), and microporous-mesoporous H+-Y zeolite (similar Brönsted-Lewis acidity than its microporous counterpart). The results showed that Ni nanoparticles are catalytically active in the hydrodesulfurization of DBT and that zeolites provide them with long-term stability. In addition, using SEA impregnation and providing mesoporosity to the zeolite improved the catalytic performance. Overall, we demonstrate that Ni nanoparticles may behave in the same manner as noble metals such as Pt, Pd, and Ir behave in hydrodesulfurization. We discuss some of the probable reasons for such behavior and remark on the role of Ni in hydrotreatment.
Efficient Method for Twist-Averaged Coupled Cluster Calculation of Gap Energy: Bulk Study of Stannic Oxide
Authors: Shaban Tameh Maliheh , Gladfelter Wayne L. , Goodpaster Jason D.
Published: December 2023

We study gap energy of the semiconducting oxide SnO2 through ab-initio calculations. DFT and coupled cluster calculations are presented and discussed. In this work, we emphasize that GGA+U does not improve the physics of the semicore d electrons in SnO2. We report an overestimation in the gap energy by finite-size scaling at the thermodynamic limit through equation-of-motion (EOM) CCSD calculations. To address one-body and many-body errors, we report a combination of the Kwee-Zhang-Krakauer1 (KZK) approach with twist averaging to explain twist averaged EOM-CCSD gap energy. In this approach, the correction to the gap energy originates from the difference between mean-field and many-body approximations and at the end the difference is added to the mean-filed gap of an infinite system to estimate the many-body gap in the thermodynamic limit. Unique single twist angles are introduced that yield cost-effective and accurate energies compared to the full twist averaging. The efficiency of the twist averaging in reducing the finite-size errors is tested through different functionals.
Importance of Site Diversity and Connectivity in Electrochemical CO Reduction on Cu

Published: December 2023

Electrochemical CO2 reduction on Cu is a promising approach to produce value-added-chemicals using renewable feedstocks, yet various Cu preparations have led to differences in activity and selectivity towards single and multi-carbon products. Here, we find, surprisingly, that the effective catalytic activity towards ethylene improves when there is a larger fraction of less active sites acting as reservoirs of *CO on the surface of Cu nanoparticle electrocatalysts. In an adaptation of chemical transient kinetics to electrocatalysis, we measure the dynamic response of a gas diffusion electrode (GDE) cell when the feed gas is abruptly switched between Ar (inert) and CO. When switching from the Ar to CO, CO reduction (COR) begins promptly, but when switching from CO to Ar, COR can be maintained for several seconds (delay time), despite the absence of the CO reactant in the gas phase. A three-site microkinetic model captures the observed dynamic behavior and shows that Cu catalysts exhibiting delay times have a less active *CO reservoir that exhibits fast diffusion to active sites. The observed delay times and the estimated *CO reservoir sizes are affected by catalyst preparation, applied potential, and microenvironment (electrolyte cation identity, electrolyte pH, and CO partial pressure). Notably, we estimate that the *CO reservoir surface coverage can be as high as 88±7% on oxide-derived (OD-Cu) at high overpotentials (-1.52 V vs. SHE) and that increases in reservoir coverage coincide with increased turnover frequencies to ethylene. We also estimate that *CO can travel substantial distances (up to 10s of nm) prior to desorption or reaction. It appears that active C-C coupling sites, by themselves, do not control selectivity to C2+ products in electrochemical COR; the supply of CO to those sites is also a crucial factor. More generally, the overall activity of Cu electrocatalysts cannot be approximated from linear combinations of individual site activities. Future designs must consider the diversity of the catalyst network and account for inter-site transportation pathways.

Background: This study aimed to compare the surface microhardness (MH) and mineral content of white spot lesions(WSLs) after using bioactive glass (BAG)casein phosphopep-tides-amorphous calcium phosphate(CPP-ACP),and nanohydroxyapatite(Nano-HAP) under pHcycling. Material and method:18 sound maxillary first premolar were used for the study.10 were selected for the vickers microhardness test, For Energy-dispersive X-ray spectroscopy analysis (EDX), the remaining 8 premolar teeth were used, 40 sections of enamel blocks (Four from each tooth) were produced from the middle part of the buccal and palatal surfaces of teeth for MH test while 48 sections of enamel blocks (Six from each tooth) were produced for EDX analysis. Enamel slabs were divided into four groups: control group that preserved in DDW, Nano-HAP, CPP-ACP and BAG group, then were demineralised using 0.1 M lactic acid and 8 wt.% carboxymethylcellulose gel to create artificial WSL. The speci-mens were subjected to a pH cycling regime for 20 days. The remineralisation potential of the specimens was studied by evaluating the surface MH, calcium (Ca), and phosphrous (P) at different stages: baseline, after production of WSLs, and after treatment with different ma-terials. The gathered data were statistically analyzed using repeated measures one-way ANOVA test and the Bonferroni test. Results: The results showed that Nano-HAP had the highest mean values of MH (157.699 kg/ mm2), Ca (50.108), and P (24.840) followed by BAG (MH=147.769 kg/ mm2, Ca=47.408, P=22.285), and the lowest mean value was found in the control group (MH=52.299 kg/ mm2, Ca=35.291, P=17.228). Bonferroni’s and Tukey's HSD test showed higher significant difference (p<0.05) from demineralization to remineralization phase in all groups, except when compared control group with WSL (Demineralization) showed non-significant difference (P>0.05). Conclusion:all tested agents have highly signif-icant remineralizing potential. Nano-HAP has the highest potential for remineralizing initial enamel caries lesions

Background: This study aims to investigate the effect of fixed orthodontic appliances and/or antihypertensive drugs on the weight of experimental rats. Materials and Methods: Thir-ty-six male Wistar albino rats were subjected to a split-mouth design study, in which an orthodontic appliance was inserted in one side to move the first molar mesially for 2 weeks while the other side acted as a control to tooth movement. The rats were allocated into three groups: group A (n = 12), without any pharmacological treatment; group B (n = 12), subcu-taneous injection of bisoprolol fumarate (5 mg/kg) daily; and group C (n = 12), subcutaneous injection of valsartan (10 mg/kg) daily. A fixed orthodontic appliance with a closing coil spring delivering 50 gm of force was used to move the first molar mesially while the incisors served as an anchor unit. The weight of the rats was measured on days 1 (the day of appli-ance insertion), 7, and 14. Results: No significant (P > 0.05) difference in the body weight of rats was found among the three groups at each time point; however, significant (P < 0.05) weight loss was noted after the first and second week of the experiment in all study groups. Conclusion: The body weight loss of rats following the insertion of a fixed orthodontic ap-pliance could be related to the effects of the appliance rather than the administered antihy-pertensive drugs.

Abstract. Endogenous intoxication plays a significant role in the pathogenesis of many diseases. The erythrocyte intoxication index and molecular weight medium are informative indicators for its research. The goal is to establish the degree of expression of endogenous intoxication syndrome in white rats against the background of drinking water with different phosphate content for 30 days. Materials and methods. The study was conducted on 36 white purebred male rats weighing 180-200 g, divided into six groups, which for 30 days consumed: the control group – settled water from the city waterworks, the animals of five experimental groups - water with the addition of sodium monophosphate in doses of 100.0; 10.0; 1.0; 0.1; 0.01; mg/dm3 in terms of elemental phosphorus. The level of endogenous intoxication was estimated by the content of molecular weight medium in blood serum at wavelengths λ = 254 and 280 nm and the level of erythrocyte intoxication index, which was determined using the method of A. A. Togaibaev, et al., which is based on the ability of the erythrocyte membrane to absorb methylene blue. Results. It was established that the content of molecular weight medium 254 in the blood serum of experimental animals significantly increased in the 1st group by 65 % (p < 0.05), the content of molecular weight medium 280 in the 1st group by 154 % (p < 0.05), in the 2nd – by 138 % (p < 0.05) and the 3rd – by 64 % (p < 0.05). Consumption of drinking water with added phosphates leads to a significant increase of erythrocyte intoxication index in the 1st group – by 186 % (p < 0.05), in the 2nd – by 142 % (p < 0.05) compared to the control. Conclusions. Consumption of drinking water with different phosphate content for 30 days causes an increase in the level of endogenous intoxication in the body of experimental rats, as indicated by an increase in the permeability of erythrocyte membranes and an increase in the erythrocyte intoxication index and molecular weight medium content, most pronounced at a concentration of 100.0 mg/dm3.

Abstract. Gout remains the most common type of inflammatory arthritis worldwide. Hypertension (AH) prevails in the structure of comorbid diseases in gout. In patients with hypertension in combination with gout, the problem of choosing treatment tactics remains quite relevant. Aim. To assess the effectiveness of the combination of basic therapy drugs for the treatment of patients with hypertension in combination with gout on quality of life indicators at the primary level of medical care. Materials and methods. Two groups of patients were formed. The first group, 36 patients who received losartan, allopurinol, atorvastatin. The second group, 36 people who received ramipril, allopurinol, atorvastatin. Quality of life was assessed using the SF-36 standardized questionnaire. The patient's functional status was assessed using the HAQ-DI health status questionnaire. Statistical analysis was performed using Statistica 6.1. Results. In the studied groups of patients, the quality of life of patients before and after treatment was evaluated. It was established that before the appointment of treatment, no significant difference was found between the groups according to the SF-36, HAQ-DI questionnaires. In patients of both groups, the indicators of the physical component of health (PCH) and the psychological component of health (PsCH) on the SF-36 scale were reduced, and a greater proportion of patients with minimal and moderate impairment of vital activity according to the HAQ-DI was registered. According to the results of the analysis, it was established that the level of quality of life according to the PCH indicator increased by 21.7 % in the first group and by 20.4 % in the second group (p < 0.01), according to the PsCH indicator – by 18.4 % and 17.5 % (p < 0.01), respectively. A probable decrease in the HAQ-DI indicator was found only in patients who received ramipril compared to the initial data before treatment by 33.3 % (р < 0.05). In patients of the I group, the share of patients with minimal disorders is increasing, and the proportion of patients with moderate disorders is decreasing, and in the II group, the prevalence of minimal and moderate disorders is increasing, which indicates the effectiveness of the prescribed therapy. Conclusions. Complex therapy (losartan or ramipril, allopurinol, atorvastatin) for 6 months in patients with hypertension in combination with gout is accompanied by a significant improvement in the quality of life according to the indicators of PCH (25.1 %, p < 0.01) and PsCH (17.7 %, p < 0.01) and degree of vital activity (25.0 %, p < 0.01).

Objectives.

To evaluate the cascade of care for the elimination of mother-to-child-transmission of human immunodeficiency virus (HIV) in Suriname and identify sociodemographic and clinical factors preventing transmission to exposed infants.

Methods.

A mixed-methods study design was used. Antenatal care data from the 2018 cross-sectional multi-indicator cluster survey on 1 026 women aged 15–49 years who had had a live birth in the previous 2 years were used. Furthermore, national data on a cohort of 279 mothers with HIV and their 317 infants born from 2016 to 2018 were evaluated. Additionally, 13 cases of mother-to-child-transmission of HIV were reviewed.

Results.

In 89.3% of cases, no mother-to-child HIV transmission occurred. Early cascade steps show that 28.4% of women had unmet family planning needs, 15% had no antenatal visits, 8% delivered outside a health facility, and 71.5% received an HIV test during antenatal care. Of the pregnant women with HIV, 84.2% received antiretroviral therapy, while 95.5% of their infants received HIV prophylactic treatment. Receiving antiretroviral therapy for the mother (odds ratio (OR) 45.4, 95% confidence interval (CI) 9.6–215.3) and the child (OR 145.7, 95% CI 14.4–1477.4) significantly increased the odds of a negative HIV test result in infants. Conversely, living in the interior decreased the odds (OR 0.2, 95% CI 0.4–0.7) compared with urban living.

Conclusions.

HIV medication for mothers with HIV and their infants remains key in the prevention of mother-to-child-transmission of HIV. Early prenatal care with follow-up should be strengthened in Suriname.

Land is a finite resource; land use affects the environment and the economy. Despite its importance, decisions on land use are not always being made using science-informed policy. This paper was developed from information presented at the ‘Collision of Land Use Forum’ in August 2010, and subsequent discussion. Recommendations include the establishment of a national Land Management Forum, a review of current guidelines for land use management, accommodation of natural capital and ecosystem services considerations in land use management processes, education of the importance of soil and land use in terms of economy and environment at all levels, and advocacy and debate to ensure both understanding and that science is the basis for creation of policy.
