Background and Study Aim.  To carry out a comparative analysis of indicators of short-term visual memory in athletes of cyclic sports (short track), martial arts (karate, taekwondo) and esports (CS:GO).
Material and Methods. The study involved athletes of percussion martial arts (n=13, age 18.8±0.52, experienced athletes), elite players of semi-professional CS:GO teams (n=10, age 19.2±0.50), short track speed skaters (n=12, age 19.1±0.25, experienced athletes). Short-term visual memory was determined using a special program for tablet computers running iOS.
Results. Certain trends have been established regarding the characteristics of the state of the body of elite athletes in martial arts, short track and esports in terms of averaged indicators. In terms of the short-term visual memory coefficient and the average percentage of errors, martial arts athletes showed the best result, and short trackers showed the worst result. The shortest average test duration was recorded for short trackers. At certain stages of the test, they dominated athletes of other specializations in terms of reaction time. However, the trend towards faster response was associated with a decrease in the accuracy of the selection, that is, a greater percentage of errors. Cyberathletes and martial arts athletes were characterized by better adaptive abilities than short track athletes.
Conclusions. The specificity of sports activities of cyberathletes determined the best results of the most difficult stage of the test both in terms of speed and accuracy. This criterion can be recommended for esports selection and prediction. The control of the cognitive functions of athletes is expedient in the course of monitoring their physical condition and is a promising direction for predicting the reliability and success of competitive activity.

Introduction and aim. Inflammation, cell proliferation, matrix deposition, and tissue remodeling are all elements of the well-structured and well-coordinated process of wound repair. The aim of this study was to analyze the effect of genistein and nicotine on polyglycolic acid (PGA) and vicryl sutures. Material and methods. Genistein and nicotine were isolated and solution was prepared and the suture material PGA and vicryl were immersed in the solution and dried. They were tested for their tensile strength and degradation values after immersion in artificial saliva (on the first day and on the 14th day). The sutures were also seen under a scanning electron microscope (SEM) for its uniform coating and the mixture formulation of genistein and nicotine were tested for their anti-inflammatory and antioxidant activity using protein denaturation assay and 2,2-diphenyl-1-picrylhydrazyl assay respectively. Results. Nicotine has a high anti-inflammatory activity on the suture material, whereas Genistein has an insignificant anti-inflammatory effect. The mixture formulation has a relatively similar anti-inflammatory effect when compared to the control. The SEM analysis shows a uniform coating of the formulation on the PGA and vicryl sutures. In comparison, PGA has shown lesser tensile strength and hence higher degradation ability. Conclusion. Nicotine and Genistein affect the tensile strength and degradation properties of the sutures.

Introduction and aim. Any hospital’s outpatient department (OPD) is regarded as the storefront of the facility, and patient satisfaction is an important measure of healthcare quality. Hence, this cross-sectional study was conducted in different OPDs at a tertiary care center. Material and methods. Two hundred patients were recruited, and structured personal interviews were conducted with questions based on the Patient Satisfaction Questionnaire Short Form (PSQ-18). T-tests and analysis of variance (ANOVA) were used to compare satisfaction scores between variables. Results. Upon analysis, 86% of the patients rated their overall experience as either ‘very good’ or ‘good’. Interpersonal manners (mean score±SD; 4.60±0.55), communication (4.39±0.66), general satisfaction (4.03±0.79), and technical qualities (3.86±0.57) were the domains in which the patients were most satisfied, while time spent with the doctor (3.77±0.89), accessibility and convenience (3.77±0.67), and financial aspects (3.37±0.83) were the areas that lagged. Conclusion. Satisfaction scores were found to vary significantly with gender, age, waiting times, and the number of visits per day. Regular patient satisfaction surveys should be conducted in all hospitals for devising interventions to provide patients with the best possible care.

Published: December 2023

Introduction and aim. Defects in the epidermal barrier, changes in sebum secretion and its composition, Malassezia spp. overgrowth, endocrine, immune, and neurological disorders are the main pathogenesis items of seborrheic dermatitis (SD). “The opioid system of the skin” was considered a new target in the diagnosis and treatment of SD. The study aimed to determine beta-endorphin (BE) levels in adult patients with seborrheic dermatitis and correlate them with the severity of symptoms and itching. Material and methods. 26 healthy and 62 SD people were examined. SEDASI scale were used to estimate the severity of symptoms and intensity of itching. The determination of the beta-endorphin level was carried out by the ELISA method with the test system Human BE NBP2 (78774 Novus Biologicals). Results. BE in the SD group was higher compared to the control group (35.5 pg/mL, 22. pg/mL, p<0.001). The level of BE in seborrheic patients did not depend on age and sex but was rising with severity of symptoms. Positive correlations were found between the level of BE and the SEDASI was 0.42 (p<.001), between the level of BE and itching was 0.332 (p=0.009). Conclusion. SD patients have an increased level of BE that positively correlates with itching and disease severity.

Introduction and aim. One of the imperative reasons for endodontic failure is an extra or missed root and root canals. Permanent mandibular lateral incisors generally present as monoradicular tooth with one or two canals, but aberrancies in the form of extra root are also rarely seen. There is insufficiency in the literary work regarding the presence of an extra root in permanent mandibular lateral incisor. We hereby report two illustrious cases of biradicular permanent mandibular lateral incisors and their endodontic management and brief review regarding the case reports published so far regarding the existence of an extra root in permanent mandibular lateral incisor in the literature. Also, we intend to apprise the scientific documentation with the aforementioned. Description of the cases. Case 1. A twenty-two-year-old male patient of Indian origin was referred to endodontic clinic for intentional root canal therapy. Pre-operative radiograph revealed 32 exhibited aberrancy in the form of an extra root, with normal periodontal structures and bone architecture. Case 2. A sixty-two-year-old male patient came to the Department of Conservative Dentistry and Endodontics with the chief complaint of pain in the lower anterior tooth region. Radiographic examination revealed root caries on the mesial side and two roots with two canals with bifurcation at the level of middle third of root. Conclusion. Clinicians should be well prepared in advance for management of any anatomical aberrancy in their clinical practice by having a scrupulous knowledge of root canal system.

THERMOGRAVIMETRIC STUDY OF THE FORMS OF MOISTURE BONDS IN KNEADING FLOUR SEMI-FINISHED PRODUCTS WITH THE ADDITION OF CRICKET FLOUR
Authors: Sereda O. , Melnyk O.
Published: December 2023

Thermal analysis methods, primarily thermogravimetric analysis (TGA), play an important role in the study of phase transitions and degradation of active food components and auxiliary substances during heating or cooling. The most important areas of application of TGA in the food industry include the analysis of patterns of changes in the mass of the studied system during its heating or cooling due to the presence of phase transitions of the first kind and chemical reactions. In this work, a study of the change in mass of biscuit products during heating was carried out. The effect of replacing wheat flour with cricket flour in the amount of 5.0% on the structure of the resulting biscuit product compared to the control was determined. This study showed a change in the distribution of forms of connection of system water with dry substances of the system and, as a result, an expansion of the range of temperatures at which water evaporation from this sample took place. However, with a further increase in the amount of cricket flour in the recipe, which has an increased protein content, an increase in the part of the system water associated with the proteins of this raw material was observed. As a result, the range of temperatures at which water evaporation occurred from biscuit products with cricket flour in the amount of 10.0% and 15.0% decreased. It was noted in the work that the most acceptable functional and technological property of biscuit products is a wider range of forms of connection of system water with dry substances of such food products, since the presence of different forms of connection of water significantly determines the organoleptic indicators of finished products, terms and conditions its storage. The results obtained by the method of thermogravimetric analysis showed that, from the point of view of expanding the spectrum of forms of connection of system water with dry substances of the studied samples, the sample with the replacement of wheat flour with flour from crickets in the3 amount of 5.0% should be considered more acceptable.

The subject of the study is the bronze encolpion crosses found at the Vodyanskoe settlement, an urban culture monument of the Golden Horde era. Material and spiritual culture of the Russian Golden Horde urban population of the 14th century is the object under study of this paper. The author analyzes personal godliness practice items of the Russian cult copper sculpture connected with spread of Christianity. The encolpions under study and their fragments were found during archaeological excavations and artefactual remains collection at Vodyanskoye settlement at different times. The aim of the study is introduction into scholarly discourse, morphological description, typological and technological characterization of these finds from the Vodyanskoe settlement. Methods and approaches used in the study include description, typological analysis, metrical approach and measurement agenda used in staurometry, system approach including morphological analysis, chemical and technological Energy dispersive X-ray analysis (EDXA). A comparison of the investigated material with the known encolpion crosses is performed. The research shows that the encolpions including their ornaments of leafs and parts discovered at the Vodyanskoe settlement are complete analogues in composition and iconography to the types of the encolpions found in the mediaeval Russian sites as well as in the other Golden Horde settlements. They can be attributed to the most numerous late Russian cross group dating back to no earlier than 13th century. Electron microprobe analysis (EMPA) of the two leafs showed that they were made up of leaded tin bronze with composition corresponding to the alloys used in Russia for encolpion casting. Winged crosses were cast into clay molds created from an impression of the finished product. The studied artifacts were interpreted in the context of the known data; they complement a handful of similar sample of items specific to the Russian population spiritual life in the 14th century. These bronze encolpion crosses are of different types the fact testifies to stylistic trends diversity in the mediaeval cult copper sculpture production of this period.
“Sarmatian” Elements in the Armament of the Chernyakhov Culture? (Some Controversial Issues in the Study of Weapons of the Late Roman Period and the Beginning of the Migration Era of Peoples in Eastern Europe)
Authors:   Institute of Archaeology of the Russian Academy of Sciences, Radyush Oleg
Published: December 2023

The paper deals with issues related to the spread of weapons of “nomadic” origin among population of the Сhernyakhov culture. The features of the funeral rite of this community have been considered. Burials with weapons are absolutely not characteristic of the Wielbark culture foundation. The majority of the cremations can be attributed to the Przeworsk element, especially those with ritual damage to weapons. In the burials of the Chernyakhov culture, according to the burial rite, the following finds are known: swords, “cut-out blades”, spears, darts, arrows, bow parts, axes, umbo, fragments of chain mail and helmets. Usually, the finds are single in the burial. The burial grounds with catacomb burials in Budzhak, burials in pits with a southern orientation of the head, individual burials in catacombs along the border of the forest-steppe and steppe zones on the left bank of the Dnieper, accompanied by Chernyakhiv imports, can be considered Sarmatian. A number of burials with weapons made in pits with a northern orientation of the head are possibly associated with the Late Scythian tradition. The swords in the inhumations known to us belong to the Eastern European tradition, i.e. they do not contain a metal pommel of type 3 according to A.M. Khazanov. Distinguishing between locally produced type 2 swords and Roman Germanic swords requires additional extensive research. In the two burials on the territory of Romania, the remains of plates were found, possibly related to the plate helmets well known among the Sarmatians. Apparently, the so-called “blades with cutouts” can be attributed to ritual weapons. Simultaneously, in the zone of the Przeworsk culture and on the Sarmatian monuments, “sword-shaped” spearheads appear. On the territory of the Chernyakhov culture, they are recorded in the zone bordering the steppe, but so far only in the form of random finds. Both types of weapons are possibly associated with the cult of the sword known among the nomadic Scythian-Sarmatian population. At the same time, the designs and decor of spearheads in some cases are possibly related to Roman ceremonial spearheads. Judging by the available archaeological data, the development of weapons among the forest-steppe tribes of Eastern Europe in the first half of the 1st millennium AD was largely associated with Central European and the Roman Empire influence, and to a lesser extent, with the steppe nomadic population, which begins to play an important role closer to the end of the Chernyakhov culture. But the presence of various nomadic groups and the influence of their traditions on the military environment are undoubted.

Published: December 2023

Aim. To evaluate the accuracy of virtual stenting in predicting the physiological effect of percutaneous coronary intervention (PCI) for multilevel coronary artery disease (CAD).

Material and methods. In order to define PCI strategy, 34 patients with multilevel CAD underwent assessment of instantaneous wave-free ratio (iFR) with mapping. Using the virtual stenting, predicted iFR (priFR) was assessed. After stent implantation, the factual iFR (fiFR) was re-assessed. A discrepancy between the priFR and fiFR by 0,03 was considered the threshold level of a significant difference and "poor agreement" criterion between measurements.

Results. Mean iFR before PCI was 0,77±0,11; after PCI, this indicator increased significantly and amounted to 0,94±0,04 (p<0,001). Comparison of the predicted and factual iFR revealed that the difference did not significantly depend on the value (rxy=-0,183; p=0,300), and mean difference between measurements was 0,013 (standard deviation, ±0,019), which indicates no systematic discrepancy and good comparability of the studied methods. In addition, correlation analysis of priFR and fiFR revealed a significant strong (Chaddock scale) direct relationship (r=0,854; p<0,001). Independent predictors of "poor agreement" were heart rate and systolic blood pressure before surgery. Discrepancy in decisions on the choice of stented lesions and the required number of stents based on coronary angiography (CAG) and MRI occurred in 21 patients (62%) and 16 patients (47%), respectively. After iFR measurement, there was a significant decrease in the mean length of affected segment (from 61,82±19,68 mm (CAG) and 49,15±19,19 mm (iFR)), which made it possible to significantly reduce the number of implanted stents from 1,91±0,57 (CAG) to 1,50±0,56 (p=0,001).

Conclusion. Mapping the iFR and virtual stenting technology makes it possible to revise the classification of coronary lesions by length, which leads to a significant reduction in the number of implanted stents and the length of stented segment. High correlation between priFR and fiFR achieved in our study indicates the high accuracy of virtual stenting in predicting the physiological effect of stenting.

Published: December 2023

Aim. To analyze the prognostic value of the Dutch Lipid Clinic Network (DLCN) and Simon Broome Register (SBR) screening criteria for familial hypercholesterolemia (FH) in men and women with dyslipidemia.

Material and methods. The study included 1233 patients with dyslipidemia.

Biomaterial samples from 421 patients were studied using Next Generation Sequencing (NGS) to identify FH-associated genes. Statistical analysis was carried out using the StatTech v program. 3.1.6 (OOO Stattekh, Russia).

Results. The most significant factors for predicting the FH in men are the level of low-density lipoprotein cholesterol (LDL-C) (1,77 times), positive family history for coronary artery disease (CAD) (6,26 times), multivessel coronary artery disease (4,05 times); in women before menopause — LDL-C (1,77 times per 1 mmol/l) and/or family history of coronary artery disease (3,31 times), in menopausal women — total cholesterol level (1,79 times per 1 mmol/l), coronary artery disease (6,52 times) and/or family history of stroke (6,04 times), xanthomas (4,24 times). Acute myocardial infarction and/or coronary stenting, arcus senilis, extracranial artery atherosclerosis did not prove to be prognostically significant for FH diagnosis.

Conclusion. Diagnostic criteria for potential FH vary among patient populations. Its diagnostic significance depends on sex, and in women, reproductive status.
The Self and Maternal Care: An Analysis of Rossella Schillachi's ‘Imprisoned Lullaby’
Authors: KİNCAL Fulya
Published: December 2023

This paper discusses the importance of the nature of maternal care as it determines healthy or unhealthy psychological development. The purpose of this essay is to demonstrate that the ongoing quality of mother-infant interaction is more important than the issue of separation from the mother, as a close but unavailable mother or caregiver may cause extreme forms of trauma in the infant. Although attachment researchers have concentrated on the mother-child proximity and the disruptive effect of separation from the mother in the development of attachment theory, less attention has been directed towards the quality of caregiving processes that contribute to the formation and maintenance of secure attachment bonds across the lifespan. This study aims to fill this gap by showing the negative effects of suppressed and unresolved grief internalized by the mother on the mental and physical health of the child. To describe the importance of a good enough mother-child relationship, this study uses the method of textual analysis. Rossella Schillaci's documentary "Ninna Nanna Prigioniera (Imprisoned Lullaby)" provides a valuable framework to analyze how an insecure attachment between a mother and an infant can be disruptive for a child's self. The documentary follows the experience of a mother who chooses to keep her newborn and young child under three with her in prison. Roscella Schillachi illustrates the development of an insecure attachment between mother prisoner Yasmina and her daughter Lolita. The documentary film shows that unresolved traumas in a caregiver can lead to insecure or disorganized attachments in infants. Although several studies suggest that mother-child proximity during the first two years is crucial to develop a healthy sense of self, this analysis of documentary provides a different approach to the concept of separation and emphasizes that proximity to a mother with unresolved trauma disturb mother-infant attachment more than separation.
Semavi Dinlerin Kutsal Kitaplarında İlahi Bir Karşılık Olarak Ölüm ve Yaşam
Authors: AKSAKAL Zeynep Nermin
Published: December 2023

Semavi dinlerin kutsal kitapları Tanah, Yeni Ahit ve Kur’ân’da ölüm ve yaşamın ilahi karşılıkla bir bağlantısı vardır. Yaratana isyanın karşılığı ölüm, sadakatin karşılığı ise yaşamdır. Ancak bu ölüm ve yaşamın hakiki anlam yanında mecazi anlamları da vardır. Bu anlamların oluşum sürecini anlamak için kutsal kitaplardaki yaratılış kıssasından başlamak gerekir. Çünkü insanın dünya hayatı ve akıbetiyle ilgili bazı dini öğretiler özünü bu kıssadaki ilk günah bahsinden alır. Bu çalışma, kutsal kitaplarda ilahi bir karşılık olarak ölüm ve yaşamın anlam alanını, ilk günah kıssası ve konuyla ilgili diğer kutsal metinler ve tefsirleri çerçevesinde tespit ve mukayese etmeyi amaçlamaktadır. Böylece bir karşılık olarak ölüm ve yaşam hakkındaki hangi öğretilerin hangi temeller üzerine kurulduğu anlaşılacaktır. Çalışma, kutsal kitaplarda ölüm konusunu yaşamla birlikte bir karşılık olarak ve ilk günah özelinde incelemesi yönüyle diğer çalışmalardan ayrı bir önemi haizdir. Çalışmada ulaşılan sonuçlara göre; Yahudi ve Hıristiyan tefsirlerinde ilk günah, insanın kötülük eğilimine sahip ölümlü tabiatının nedenidir. Bu yaklaşım günah ve kefaret, ilahi buyruklara bağlılık ve mükâfat üzerine kurulu tüm Yahudilik tarihinin temeli iken Hıristiyanlıkta asli günah, vaftiz, kurtarıcı Mesih’le özdeşleştirilmiş kefaret ve gelecek yaşam öğretilerinin temelidir. Kur’ân ve tefsirlerine göre ise insanın yaratılıştan iyilik ve kötülük potansiyeline sahip ölümlü tabiatı, ilk günahın nedenidir. Bu durum, ilk günahla bağlantısı kurulan kadim öğretileri bozan unsurlar içerir. Diğer taraftan kutsal kitaplarda ilahi bir karşılık olarak ölüm ve yaşamın mecazen ortak bir anlam alanı vardır. Buna göre ölüm, kötülüklerin karşılığı olarak dünya ve ahirette kötü bir hayat sürmek iken yaşam, iyiliklerin karşılığı olarak dünya ve ahirette iyi bir hayat sürmektir. Dünyevi kötü ve iyi yaşam Tanah’ta daha ziyade maddi hayat koşulları ve ömrün süresiyle ilgiliyken Yeni Ahit ve Kur’ân’da maneviyatla, kalbin diri ve huzurlu olup olmamasıyla ilgilidir. Uhrevi kötü ve iyi yaşam ise tüm kitaplarda cehennem ve cennet hayatı demektir.

We study markets with mixed manna, where m divisible goods and chores shall be divided among n agents to obtain a competitive equilibrium. Equilibrium allocations are known to satisfy many fairness and efficiency conditions. While a lot of recent work in fair division is restricted to linear utilities and chores, we focus on a substantial generalization to separable piecewise-linear and concave (SPLC) utilities and mixed manna. We first derive polynomial-time algorithms for markets with a constant number of items or a constant number of agents. Our main result is a polynomial-time algorithm for instances with a constant number of chores (as well as any number of goods and agents) under the condition that chores dominate the utility of the agents. Interestingly, this stands in contrast to the case when the goods dominate the agents utility in equilibrium, where the problem is known to be PPAD-hard even without chores.
Collective Belief Revision
Authors: Aravanis Theofanis I.
Published: December 2023

In this article, we study the dynamics of collective beliefs. As a first step, we formulate David Westlund’s Principle of Collective Change (PCC) —a criterion that characterizes the evolution of collective knowledge— in the realm of belief revision. Thereafter, we establish a number of unsatisfiability results pointing out that the widely-accepted revision operators of Alchourrón, Gärdenfors and Makinson, combined with fundamental types of merging operations —including the ones proposed by Konieczny and Pino Pérez as well as Baral et al.— collide with the PCC. These impossibility results essentially extend in the context of belief revision the negative results established by Westlund for the operations of contraction and expansion. At the opposite of the impossibility results, we also establish a number of satisfiability results, proving that, under certain (rather strict) requirements, the PCC is indeed respected for specific merging operators. Overall, it is argued that the PCC is a rather unsuitable property for characterizing the process of collective change. Last but not least, mainly in response to the unsatisfactory situation related to the PCC, we explore some alternative criteria of collective change, and evaluate their compliance with belief revision and belief merging.
STATE-OF-THE-SCIENCE REPORT Trends in Floristic Quality Assessment for Wetland Evaluation
Authors: DeBerry Douglas
Published: December 2023

Over the past two decades, much has been written about the use of bioassessment tools to evaluate wetland condition. Interest in bioassessment has originated from a need to establish parameters for “biological integrity” in wetland ecosystems, whether for scientific research, natural areas assessment, inventory and monitoring, or in response to regulatory mandate. On the latter point, the need has been, in part, a reaction to Clean Water Act directives to “restore and maintain the chemical, physical, and biological integrity of the Nation’s waters” (33 U.S.C. §1251). For wetland scientists and managers, identifying a sampling focus for chemical or physical integrity (e.g., dissolved oxygen, temperature) has been a much more straightforward task than finding adequate methods for measuring biological integrity, an ambiguous concept that defies precise definition.
Kite-based Aerial Photography (KAP): A Low Cost, Effective Tool for Wetland Research
Authors: Andresen Christian
Published: December 2023

The development and utilization of new technologies in wetland research is key for advancing knowledge, conservation, and management of these important ecosystems. While satellite-based remote sensing has proven valuable for understanding mostly regional to continental scale changes in wetlands, the high spatial heterogeneity of wetland plant communities and landscape units has proven challenging to characterize with the use of satellite technologies
Wetland Habitat Assessments at the Rochester Embayment Area of Concern on the South Shore of Lake Ontario, USA
Authors: Gefell Dan
Published: December 2023

Wetlands in urban areas along Lake Ontario have been subject to various forms of degradation. The Great Lakes Water Quality Agreement (GLWQA) of 1972 between the United States and Canada was initiated to address the degradation of the physical, chemical, and biological integrity of the Great Lakes. The GLWQA of 1987 (Annex 2) identified locations that have serious contamination and other degradation issues to a greater degree than the rest of the Great Lakes basin, and designated these locations as Areas of Concern (AOCs). AOCs are assessed through preparation of remedial action plans (RAPs) to determine which of 14 “beneficial uses” related to human and intrinsic values of the ecological system remain impaired, and to identify actions that will restore beneficial uses.
An Approach to Monitoring Coastal Marsh Migration in the Northeast by Ralph W. Tiner and Peter L. M. Veneman
Authors: Tiner Ralph
Published: December 2023

Global climate change has significant implications for ecosystems worldwide. An increase in sea-level is one of its many environmental impacts. Melting of Arctic and Antarctic ice and thermal expansion of ocean water are causing sea levels to rise at rates higher than in the past century. This rise is affecting vegetation in low-lying areas along most coasts. Changes in coastal vegetation attributed to rising seas is not a new phenomena as scientists have reported finding remains of trees in salt marshes and underwater in the mid-1800s and early 1900s. “Marine transgression” has occurred on coastal lands since the last glaciation as sea level initially rose rapidly with the melting of continental glacial ice.
Variations in shoreline vegetation and turbidity of shallow lakes by Ryan D. Sullivan, La Toya Kissoon, Donna Jacob, Mark Hanson, Emily K Fischbach, and Marinus Otte
Authors: Sullivan Ryan
Published: December 2023

shoreline vegetation provides vital ecological services and can impact water quality of shallow lakes. We determined the area and composition of shoreline vegetation for 20 shallow lakes of varying turbidities in the Prairie Parkland Province of Minnesota. We examined differences in shoreline vegetation between clear and turbid lakes and identified relationships between shoreline vegetation and several lake environmental variables (lake depth, submerged vegetation cover, turbidity, chlorophyll-a, total phosphorus, Ca+Mg, conductivity, and pH). In contrast to turbid lakes, the clear lakes had greater emergent and submerged vegetation cover. Typha spp. dominated the shorelines of clear lakes, while woody vegetation dominated the shorelines of the turbid lakes. Redundancy analysis (RDA) showed depth and chlorophyll-a concentrations were related to emergent vegetation composition. The percent shoreline of Typha spp. was negatively associated with chlorophyll-a concentrations and the percent shoreline of woody vegetation was positively associated with water depth.

The Environmental Protection of Wetlands under International Law
Authors: Murcia María
Published: December 2023

The environmental protection of wetlands under international law is accomplished through various methods including conventions, customary principles of international water law and decisions of the International Court of Justice. The most representative instrument is the Ramsar Convention, which specifically focuses on wetlands protection through conservation and “wise use” of such an ecosystem and its resources. The principles of international water law codified in the 1997 United Nations Watercourses Convention provide a management approach to be applied to each watercourse, requiring all watercourse States to ensure the protection and preservation of ecosystems through the application of principles of cooperation, reasonable utilization and causing no harm along the entirety of each basin. An analysis of these instruments reveals the best practices to manage wetlands in transboundary basins around the world.
Aula Prática: Efeito de cádmio e pH na função de uma enzima: a luciferase de vagalume

A desnaturação de proteínas pode ser causada por pHs extremos e metais pesados, como chumbo e mercúrio. Pequenas variações de pH ou baixas concentrações de metais pesados também afetam a estrutura e função de proteínas como enzimas, tendo efeitos tóxicos no metabolismo, entretanto, tais efeitos não são facilmente visualizados. A enzima luciferase, que catalisa a reação de oxidação da luciferina em vagalumes, produz luz verde-amarela em pH fisiológico. Em pH ácido ou na presença de certos metais pesados a cor da luz emitida muda para o laranja-avermelhado. Estas enzimas ao ligar os metais pesados ou prótons, mudam de conformação, afetando as interações eletrostáticas entre os aminoácidos do sítio-ativo e a molécula-produto (oxiluciferina), mudando a cor da luz emitida. Nesta aula prática a luciferase clonada do vagalume Amydetes vivianii, que é especialmente sensível ao cádmio, é utilizada para indicar variações de concentração deste metal e, também, para mudanças de pH, por meio da alteração da cor da luz do verde-amarelo-laranja. A bioluminescência produzida é, facilmente, visualizada em ambiente escuro, podendo ser fotografada com câmera de celular convencional.
