Children, Donkeys and Eponyms at Dūr-Katlimmu
Authors: Nahm Werner
Published: November 2021

The Middle Assyrian herding texts from Dūr-Katlimmu are brought into a temporal order by following the animals from year to year, with new insights into the management of the herds. The use of percentages is confirmed. Three new joins of published texts are found. Based on the lists of serfs and rations the prosopography and ethnography of the šiluḫlu community is refined. Taken together, this leads to substantial corrections of the eponym sequence under Salmānu-ašarēd (Shalmaneser) I and Tukultī-Ninurta I. The texts show the impact of an epizootic and of three wars, in particular ups and downs in the war against Babylonia. The destruction of the šiluḫlu community under Tukultī-Ninurta I is described and an interpretation for it proposed.
Endogenous Expectations Management with Network Effects: A Note
Authors: Choi Kangsik , Lim Seonyoung
Published: November 2021

We examine the endogenous choice of commitment device to consumers’ expectations with network effects. Under Cournot competition, we show that choosing commitment to expectations for each firm is a dominant strategy regardless of the strength of network effects. However, under Bertrand competition, three types of commitment with both/no commitment/multiple emerge in equilibrium depending on the strength of network effects. Thus, we obtain different Pareto efficiency between Bertrand and Cournot competition, depending on the intensity of competition.
Positive answer to the invariant and hyperinvariant subspaces problems for hyponormal operators
Authors: Mecheri Salah
Published: November 2021

The question whether every operator on infinite-dimensional Hilbert space 𝐻 has a nontrivial invariant subspace or a nontrivial hyperinvariant subspace is one of the most difficult problems in operator theory. This problem is open for more than half a century. A subnormal operator has a nontrivial invariant subspace, but the existence of nontrivial invariant subspace for a hyponormal operator 𝑇 still open. In this paper we give an affirmative answer of the existence of a nontrivial hyperinvariant subspace for a hyponormal operator. More generally, we show that a large classes of operators containing the class of hyponormal operators have nontrivial hyperinvariant subspaces. Finally, every generalized scalar operator on a Banach space 𝑋 has a nontrivial invariant subspace.
Xenological Subjectivity: Rosi Braidotti and Object-Oriented Ontology
Authors: Vivaldi Jordi
Published: November 2021

The conceptualization of the notion of subjectivity within the Anthropocene finds in Rosi Braidotti’s posthumanism one of its most explicit and profuse modulations. This essay argues that Braidotti’s model powerfully accounts for the Anthropocene’s subjectivity by conceiving the “self” as a transversal multiplicity and its relationality to the “others” and the “world” as non-hierarchized by nature–culture distinctions; however, by being ontologically grounded on a neo-Spinozistic monism, Braidotti’s model blurs the notions of finitude, agency, and change, obscuring the possibility of critical dissent while decreasing the overall theory’s consistency. An alternative ontological model capitalizing on these elements can be found in Object-Oriented Ontology (OOO) and its notion of withdrawal. By associating OOO’s non-onto-taxonomical pluralism with Braidotti’s posthuman subjectivity, this essay aims at ontologically discretizing the latter in order to overcome these limitations. Grounded on this association and invoking a narrative imaginary propelled by the Greek terms xenos (guest-friend) and xenia (hospitality), the article paves the way for a form of subjectivity deviating from Braidotti’s ecological model and defined as xenological, arguing that, within the context of the Anthropocene, it constitutes an adequate alternative to Braidotti’s subjectivity.
Reassessing Syntax-Related ERP Components Using Popular Music Chord Sequences
Authors: Goldman Andrew , Harrison Peter M. C. , Jackson Tyreek , Pearce Marcus T.
Published: November 2021

Electroencephalographic responses to unexpected musical events allow researchers to test listeners’ internal models of syntax. One major challenge is dissociating cognitive syntactic violations—based on the abstract identity of a particular musical structure—from unexpected acoustic features. Despite careful controls in past studies, recent work by Bigand, Delbe, Poulin-Carronnat, Leman, and Tillmann (2014) has argued that ERP findings attributed to cognitive surprisal cannot be unequivocally separated from sensory surprisal. Here we report a novel EEG paradigm that uses three auditory short-term memory models and one cognitive model to predict surprisal as indexed by several ERP components (ERAN, N5, P600, and P3a), directly comparing sensory and cognitive contributions. Our paradigm parameterizes a large set of stimuli rather than using categorically “high” and “low” surprisal conditions, addressing issues with past work in which participants may learn where to expect violations and may be biased by local context. The cognitive model (Harrison & Pearce, 2018) predicted higher P3a amplitudes, as did Leman’s (2000) model, indicating both sensory and cognitive contributions to expectation violation. However, no model predicted ERAN, N5, or P600 amplitudes, raising questions about whether traditional interpretations of these ERP components generalize to broader collections of stimuli or rather are limited to less naturalistic stimuli.
Perception of Musicality and Emotion in Signed Songs
Authors: Mangelsdorf Heather Harden , Listman Jason , Maler Anabel
Published: November 2021

This study investigated how signed performances express musical meaning and emotions. Deaf, Hard-of-Hearing (HoH), and hearing participants watched eight translated signed songs and eight signed lyrics with no influence of music. The participants rated these videos on several emotional and movement dimensions. Even though the videos did not have audible sounds, hearing participants perceived the signed songs as more musical than the signed lyrics. Deaf/HoH participants perceived both types of videos as equally musical, suggesting a different conception of what it means for movement to be musical. We also found that participants’ ratings of spatial height, vertical direction, size, tempo, and fluency related to the performer’s intended emotion and participants’ ratings of valence/arousal. For Deaf/HoH participants, accuracy at identifying emotional intentions was predicted by focusing more on facial expressions than arm movements. Together, these findings add to our understanding of how audience members attend to and derive meaning from different characteristics of movement in performative contexts.
School Without Racism? How White Teachers in Germany Practice Anti-Racialism
Authors: Burhoff Hanna Maria
Published: November 2021

This qualitative study investigates how white teachers at a German Catholic comprehensive school conceptualize issues of “race” and racism in the context of being a “School without Racism – School with Courage” (SOR-SMC). By collecting signatures and exhibiting yearly projects, more than 3,300 schools in Germany brand their school to be “without racism”. I found the branding of my researched school to be a form of “anti-racialism” that opposed “race” and racism as concepts but did not tackle any underlying racist structures (Goldberg 2009, 10). The teachers I interviewed took the SOR-SMC branding for granted and assumed that the school was racism-free. They thereby engaged in silent racism and reproduced racist connotations and structures without challenging them (Trepagnier 2001). Being anti -racist is not accomplished by declaring a school as racism-free. Instead, white teachers need to understand that anti-racism involves a deeper engagement with the structures that keep “racial” inequality in place (Goldberg 2009, 10).

The Effect of Person-Environment Fit on Public Servant Integrity and Performance: Investigating the Moderating Role of Public Service Motivation
Authors: Tannimalay Sangeetha , Abdul Rahim Noor Fareen , Hong Meen Chee
Published: November 2021

Individual performance is measured by a person's contribution to attaining this objective, whereas public organisation performance is measured by goals achieved in accordance with its mission statements. Positive individual behaviour is important for positive life outcomes, such as professional ethics. Individuals with strong integrity between their psychological (spiritual) and physical (physical) functions are one of the determinants of individual performance in organisations. Integrity is a promise to do everything in line with right and ethical principles, as well as values and standards, and there is consistency in continuing to make these commitments in every scenario without seeing any chance or coercion to break them. Individual integrity and performance are strongly influenced by the person-environment fit (person-job fit and person-organization fit). Due to the several corruption cases in Malaysia, the impacts of person-environment fit (person-job fit and person-organization fit) on individual integrity and performance of public sector personnel are investigated in this study. The suggested model was tested using partial least squares on a sample of 214 public sector employees in Penang. Integrity and individual performance is positively influenced by both person-job fit and person-organization fit, with person-organization fit having a stronger effect. Furthermore, the moderating effects of Public Service Motivation in the relationship between person-environment fit and the integrity and individual performance are not significant. As a result, it is critical to design strategies and implement suitable organisational environments in order to successfully raise the integrity and performance levels of public sector employees/

Sustainable design: Aspects of sustainable product development
Authors: Ruffino Rico
Published: November 2021

When NC State University recently hired me to lead a course concentration in sustainable design, I began to hone in on what sustainable product development and design translate to and its actionable applications. Sustainable product development and design of current and future consumer products and services are methods that create a proactive versus a reactive approach. The development of sustainable products and systems must start at the beginning phase of ideation and continue through the entire process to achieve multiple design purposes and duration with a designated end-of-life plan. In contrast, generally, products are developed with end of life and longevity as a secondary thought, and with recycling as a potential option. If the goal is the longevity of a product or service, one needs to look beyond recycling and more at the concept of development. A sustainable product development approach and design thinking are how to accomplish product longevity.
Achievements of the academic grammar school
Authors:   Institute of the Ukrainian Language of National Academy of Sciences of Ukraine, Horodensʹka Kateryna
Published: November 2021

This study aims at investigating the development of grammatical theory at the Institute of the Ukrainian Language for the last 30 years. The paper summarizes achievements in grammar theory from applying the functional, i.e., semantic and grammatical, approach developed by I.R. Vykhovanetsʹ to differentiating units into word and nonword classes and distinguishing morphological categories of major word classes. This facilitated the establishment of the theoretical basis of functional and categorical morphology. The author analyses studies in formal grammatical, semantic, functional, categorical, deri vational, and anthropocentric syntax that attest to the multidimensional growth of a syntactic theory and main aspects of the Ukrainian word formation on the basis of semantic and categorical syntax and a formant- and stem-based derivatology. Some of the latest multi-pronged processes in word formation reflect dynamics of word formation rules, the replenishment of word formation resources, and the development of the word-formation system of Standard Ukrainian. The solving of a complex set of theoretical issues in the modern Ukrainian word-formation introduced the methodological foundations for the recent normative description of the word formation system of Standard Ukrainian. The article addresses issues in studies on applied grammar determined by the process of glo balization and democratization of the Ukrainian society and the needs of Modern Ukrainian language practice to be met. Particular importance is attached to the grammatical prescriptive norms in the professional use, the actualization of case forms appearing in the passive vocabulary, and the dynamics of morphological and syntactic norms in various functional and stylistic dimensions of Standard Ukrainian. Keywords: functional grammar, functional morphology, functional syntax, categorical grammar, categorical syntax, categorical word formation, classification of parts of speech, morphological categories.
Onomastic research in the Institute of the Ukrainian Language of the National Academy of Sciences of Ukraine: Origin, current state, and prospects
Authors:   Institute of the Ukrainian Language of National Academy of Sciences of Ukraine, Verbych Svіatoslav
Published: November 2021

This article analyses the basic stages of onomastic studies development at the Institute of the Ukrainian Language of the National Academy of Sciences of Ukraine since the 1950s till the present within the Potebnia Institute of Linguistics. The paper focuses on Institute’s main directions and ideas, e.g., etymological research in hydronymics, anthroponimics, oikonimics, and ethno- nimics based on the traditions of comparative-historical approach. It also reveals important issues of contemporary studies as follows: 1) the etymology of proper nouns, i.e., personal, geographical and ethnic names, with respect to the systematic and historical approaches; 2) lexicographic studies on anthroponyms, hydronyms, and oikonyms; analysis of modern onimicon of Ukraine in accordance with current spelling norms of Standard Ukrainian; 3) systematization of the Ukrainian onomastic research and indexes. The achievements of the Ukrainian onomastics are reinterpreted through the lenses of numerous monographs, scientific collections, and historical and etymological dictionaries of hydronyms and oikonyms. A periodical Study of Onomastics and Etymology is viewed as a successful case of cooperation with the Ukrainian Language Insti-tute of the National Academy of Sciences of Ukraine and regional onomastic centers to share the outcome of national onomastic research outside Ukraine. The article outlines main goals that the Ukrainian academic onomastics must achieve, such as the following: 1) to develop Ukrainian onomastic science on the basis of objective data analysis, e.g., from the characteristics of a single fact to the concept formulation; 2) to expand the empirical basis of onomastic research; 3) to promote outcomes of onomastic studies among students of national Ukrainian universities. Keywords: onomastics, onomastic card index, onomastic studies, traditions of comparative-historical linguistics, onomastics group in the Department of History of the Ukrainian Language and the Institute of the Ukrainian language of the National Academy of Sciences of Ukraine.
Resources and methods of neosemantization of the modern Ukrainian vocabulary
Authors:   Institute of the Ukrainian Language of National Academy of Sciences of Ukraine, Tsyhvintseva Iuliia
Published: November 2021

This article focuses on the dynamic processes at the lexical level. The research data, e.g., academic dictionaries and dictionaries of new words, online media texts, and specialized professional sites, the Ukrainian journalism, and posts by Facebook users, indicate the emergence of a large number of new meanings of various word classes words well-known in the modern Ukrain- ian language practice. Some of them are already included in dictionaries, and, therefore, have acquired definitions used in this study. Examples not attested in lexicographic sources are reinterpreted in accordance with their new meanings. The author focuses on the ability of the language to update its vocabulary within its own resources through semantic derivation, hidden borrowings, and the use of the available derivation model referring to a new concept. A phenomenon of semantic derivation is outlined and the mechanisms of its main types, e.g., metaphorical and metonymy transfer of meaning, amplification and semantic narrowing, are explicated. The paper looks into the basis for such a unit assimilation process, i.e., the main groups of modern hidden borrowings and resources. The author considers the phenomenon of the reuse of an existing derivation model as a way of updating the semantics of a word and classifies neosemantisms not only by the method of creation but also by lexical and word-formation categories and types of polysemy. The use of neosemantisms in Standard Ukrainian proves their functional and word-formation activity, which shows a constant qualitative development of the language and an increase of its naming resources. Keywords: neosemantism, semantic derivation, polysemy, hidden borrowing, recurrent derivational model, homonym.
Tuberculosis Infection in Children and Adolescents: Testing and Treatment
Authors: Nolt Dawn , Starke Jeffrey R.
Published: November 2021

Tuberculosis (TB) remains an important problem among children in the United States and throughout the world. There is no diagnostic reference standard for latent tuberculosis infection (also referred to as tuberculosis infection [TBI]). The tuberculin skin test (TST) has many limitations, including difficulty in administration and interpretation, the need for a return visit by the patient, and false-positive results caused by cross-reaction with Mycobacterium bovis–bacille Calmette-Guerin vaccines and many nontuberculous mycobacteria. Interferon-gamma release assays (IGRAs) are blood tests that use antigens specific for M tuberculosis; as a result, IGRAs yield fewer false-positive results than the TST. Both IGRAs and the TST have reduced sensitivity in immunocompromised children, including children with severe TB disease. Both methods have high positive predictive value when applied to children with risk factors for TBI, especially recent contact with a person who has TB disease. The advantages of using IGRAs and diminished experience with the placement and interpretation of the TST favor expanded use of IGRAs in children in the United States. There are now several effective and safe regimens for the treatment of TBI in children. For improved adherence to therapy, the 3 rifamycin-based regimens are preferred because of their short duration. Daily isoniazid can be used if there is intolerance or drug interactions with rifamycins. A TB specialist should be involved when there are questions regarding testing interpretation, selection of an appropriate treatment regimen, or management of adverse effects.
Mediatisation of alternative energy issues in European mass media
Authors: Butyrina  M. , Harkavenko Y.
Published: November 2021

The study presents the results of content monitoring of the European press on the subject of alternative energy. The data collected from the current newspaper articles and selected by keywords “alternative energy sources”, “diversification of energy sources”, “energy transition” and “energy markets” are summarised. Trends, problems and prospects of energy transition are revealed. Both pan-European trends and the dynamics of transition in specific countries (Germany, France and Great Britain) are presented. It is noted that the triangle of sustainable development, which is “economy — ecology — society”, needs a powerful media component to ensure public discussion and social approval of the latest energy technologies. It has been proved that the energy turn provides sufficient information support for society to adapt to alternative energy sources and allows key actors to make informed policy decisions.
The role of solutions journalism in the implementation of sustainable development goals, including the transition of the society to renewable energy, is pointed out. It is noted that solutions journalism, as a new direction of media activity, corresponds to the interpretive contextual function of journalism, which provides coverage of productive precedents for solving social problems in different countries. The role of the media in popularisation of such precedents is shown. The tools of solutions journalism used in the European countries are indicated, namely engaging the expert community, providing positive forecasts, appealing to the productive experience of other countries, covering the political side of the issue and opportunities for savings through the transition to alternative energy sources, and promotion of green technologies.
ЗНЕСОЛЕННЯ МІНЕРАЛІЗОВАНИХ ВОД ПРИ ВИКОРИСТАННІ РЕАГЕНТНИХ МЕТОДІВ
Authors: Трус Інна М. , Гомеля Микола Д.
Published: November 2021

Вирішення проблем водозабезпечення та охорони вод в рамках водних екосистем є актуальним питанням сьогодення. В роботі вирішено важливу науково-технічну проблему розробки високоефективних методів водопідготовки та очищення стічних вод від забруднень, що дозволяє створити маловідходні технології демінералізації. Нанофільтраційні технології водопідготовки дозволяють отримувати високоякісну питну воду та технологічну воду з необхідними показниками. Концентрати, які утворюються при нанофільтраційному очищенні високомінералізованих природних та шахтних вод, характеризуються підвищеним вмістом іонів жорсткості і сульфатів. Ефективного очищення води від сульфатів можна досягти при застосуванні синтезованого алюмінату натрію та вапна. Ступінь пом’якшення та очищення концентратів від сульфатів залежить від дози вапна та алюмінату натрію, співвідношення реагентів, реакції середовища. Ефективність вилучення сульфатів з води зростає з підвищенням дози вапна при постійній дозі коагулянту та з підвищенням дози гідроксоалюмінату натрію при постійній дозі вапна. Перевищення дози вапна на 20 % більше від стехіометричного співвідношення є недоречним, оскільки призводить до незначного підвищення ефективності вилучених сульфатів з води. Ефективність вилучення сульфатів за постійних доз вапна зростає з підвищенням дози коагулянту до 20–60 % від стехіометричної кількості сульфатів. При доведенні рН середовища до 7–8 за допомогою вуглекислого газу досягнуто підвищення ефективності вилучення іонів жорсткості та сульфатів. При знесоленні високомінералізованих вод при оптимальній дозі реагентів концентрація сульфатів знизилась до 69–89 мг/дм3 та іонів жорсткості – до 0.44–1.15 мг-екв/дм3. В роботі були розраховані рівняння регресії для залежності залишкових концентрацій сульфатів і іонів жорсткості у воді в залежності від дози вапна і алюмінату натрію.

Матеріали на основі олова широко використовуються в сенсорній технології, а також для створення каталізатора. Отримання матеріалів з найбільшою питомою площею поверхні, яку може забезпечити об'ємно-пористий нано-впорядкований та структурований матеріал, є важливим завданням. У даній роботі запропоновано електроосадження компактних наноструктурованих катодних осадів олова з сульфатного розчину, що містить добавку ОП-10. Наявність відповідного типу добавок у розчині та значний час осадження спричинили утворення наноструктурованої поверхні олов’яних осадів. Встановлено, що найвища продуктивність електровідновлення СО2 досягнута на електроформованих олов'яних електродах, час осадження яких становив дві години. У мембранній комірці відкритого типу при швидкості барботування СО2 5 мл/хв у діапазоні потенціалів –1.5… –1.8 В (відносно Ag / AgCl) вихід за струмом коливається в межах 11… 12.5 %. Було показано, що максимальна швидкість утворення форміату натрію на електроосадженому наноструктурованому каталізаторі спостерігалася при електродному потенціалі –1.8 В (відносно Ag / AgCl) і є вдвічі вищою, ніж на полірованому олові.

DEPENDENCIES BETWEEN MODEL INDICATORS OF THE BASIC AND THE SPECIALIZED SPEED IN HOCKEY PLAYERS AGED 13-14
Authors: Antonov A.
Published: November 2021

PURPOSE The aim of our research is to establish the degrees and directions of dependence between the main forms of manifestation of the basic and specialized speed. The subject was 20 boys born in 2005 and 2006.
METHODS Through tests and variance analysis (VA) we determine the level of the main forms of the basic and specialized speed, and through correlation analysis (CA) and intercriteria analysis (ICrA) we establish the existence of possible connections and degrees of dependence between them.
RESULTS: By using VA we were able to characterize the average level, the level of dispersion and the distribution of the values of the studied indicators.
Correlations and dependencies have been established by using CA, traditionally applied by sports science. We have also applied the innovative ICrA in order to confirm or reject the established correlations, directions and degrees of dependence.
CONCLUSIONS: The conducted CA and ICrA have shown that the means for the development of the basic linear speed (BLS) and specialized linear speed (SLS) do not have a significant impact on the development of the special complex speed. ICrA also indicates a lack of correlations and dependencies between BLS and SLS, which, however, is not confirmed by CA.

Eucheuma seaweed from tropical waters habitat mainly contains carrageenan, a type of hydrocolloid potential for hydrogel production. This study aims to determine the characteristics of hydrogel formulated from composite i- and k-carrageenan combined with polyvinyl alcohol (PVA) which, could be used further for wound dressing application. The concentrations of composite i/k-carrageenan used were 1.0%, 1.5%, 2.0%, 2.5% and 3.0% w/w, and the PVA concentration was 12.5% w/w. Composite i/k-carrageenan in a proportion of 6:4 by weight. The hydrogel was irradiated using 60Co g-rays with the irradiation dose of 25 and 2 kGy.h-1. The concentration of composite i- and k-carrageenan influenced the gel fraction, water holding capacity, tensile strength, elongation, and surface morphology of the hydrogel. The optimum formula of irradiated composite hydrogel was obtained from 3.0% w/w of composite i/k-carrageenan. The formula had a gel fraction of 61.67%, water holding capacity of  1067.12%, tensile strength of  32.37 x 10-3 MPa, and elongation of  251.67%. Interestingly, the product with the optimum formula had a porous surface morphology and transparency, which are applicable for wound dressing purposes.
Gastrodin represses hydrogen peroxide-induced oxidative stress in retinal pigment epithelial cells through p38MAPK/iNOS pathway
Authors: Zhou Xingli , Zhao Ximing
Published: November 2021

Elevated reactive oxygen species (ROS) induce oxidative damage in retinal pigment epithelium (RPE) and contribute to the development of age-related macular degeneration (AMD). Gastrodin plays an antioxidant role in distinct diseases, such as epilepsy, cerebral ischemia, Alzheimer’s disease, and cardiovascular diseases. However, the function of gastrodin in AMD remains unclear. Human RPE (ARPE-19) cells were incubated with 300 μM hydrogen peroxide (H2O2) for 24 hours. The results showed that H2O2 decreased cell viability and promoted the cell apoptosis of ARPE-19 cells. H2O2-induced ARPE-19 cells were then treated with different concentrations of gastrodin. Gastrodin increased cell viability of H2O2-induced ARPE-19 cells, suppressed the cell apoptosis of H2O2-induced ARPE-19 cells with reduced B-cell lymphoma (Bcl)-2 like protein (Bax), and enhanced Bcl-2. The levels of ROS were enhanced, malondialdehyde (MDA) was up-regulated, and superoxide dismutase (SOD) and glutathione (GSH) were down-regulated in H2O2-induced ARPE-19 cells. However, gastrodin reduced the levels of ROS and MDA and elevated SOD and GSH in H2O2-induced ARPE-19 cells. Furthermore, H2O2-induced increase of inducible nitric oxide synthase (iNOS) and p-p38 proteins in ARPE-19 was reversed by gastrodin. In conclusion, gastrodin exerted antiapoptotic and antioxidant capacities to protect against H2O2-induced oxidative stress in RPE, thereby acting as a potential agent for managing AMD.

Authors: ÖZTÜRK Zafer , BİLGİL Halis , ERDİNÇ Ümmügülsüm
Published: November 2021

The new priority in the grey modelling is to build new models that have more accurate forecasting power than the previous ones. This paper aims to develop the prediction performance of the existing continuous grey models. Therefore, a novel continuous grey model (OCCFGM(1,1)) is proposed with conformable fractional derivative. The numerical results of three case studies show that the novel model's prediction accuracy is higher than other competitive models, and the proposed model is more reasonable for practical cases.
Acute Effects of Foam Rolling Exercises on Arterial Stiffness, Flexibility and Autonomic Nervous System Function in Young and Middle-Aged Women
Authors: Lee Cheonok , Lee Sewon
Published: November 2021

PURPOSE: Arterial stiffness is an independent risk factor for cardiovascular disease and inversely associated with flexibility. Self-myofascial release (SMR) using a foam roller is a popular intervention to improve flexibility, restore the muscles, fascia, tendons, and ligaments, and regain soft-tissue extensibility. This study aimed to investigate whether a single bout of SMR has a beneficial effect on arterial stiffness and the function of the autonomic nervous system and the relationships among these variables in young and middle-aged women by age.METHODS: Ten healthy young (23.20±0.59 years) and 10 middle-aged women (44.50±0.91 years) completed an instructed SMR using a foam roller. Brachial-ankle pulse wave velocity (baPWV), augmentation index (AIx), trunk flexibility, shoulder flexibility, heart rate variability, including standard deviation of normal R-R intervals (SDNN), and the root mean square of the standard deviation of the time between heartbeats (RMSSD) were measured before and after one 30-minutes bout of SMR.RESULTS: After one bout of SMR, trunk and shoulder flexibility increased in both groups of women, while AIx decreased significantly (from 6.9±2.9 to -1.9±4.6%, p=.0072, young women group; from 22.1±3.4 to 14.7±1.7%, p=.0049, middle-aged women group). However, the baPWV, RMSSD, and SDNN did not change. In the analysis of correlations between all measured variables, changes in AIx showed negative correlations with flexibility and SDNN.CONCLUSIONS: This study suggests that one bout of SMR using a foam roller positively affected arterial stiffness in women by reducing AIx and improving flexibility.

ABSTRACT Background: The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) has been recently developed as a brief, practical, and feasible tool for cognitive impairment in multiple sclerosis (MS). Objective: This study aimed to provide continuous and discrete normative values for the BICAMS in the Brazilian context. Methods: Normatization was achieved using six hundred and one healthy controls from the community assessed at five Brazilian geopolitical regions. Results: Mean raw scores, T scores, percentiles, and Z scores for each BICAMS measure are provided, stratified by age and educational level. Regression-based norms were provided by converting raw scores to scaled scores, which were regressed on age, gender, and education, yielding equations that can be used to calculate the predicted scores. Regression analyses revealed that age, gender, and education significantly influenced test results, as in previous studies. Conclusions: The normative data of the BICAMS to the Brazilian context presented good representativeness, improving its use in daily clinical practice.

Published: November 2021

ABSTRACT Background: Sleep architecture and sleep hygiene might be disrupted by several pathogenetic mechanisms, and the effect of smoking has not been evaluated. Objective: To investigate the effect of smoking on sleep hygiene behaviors that might be associated with the deterioration of quality-of-life (QoL) parameters. Methods: In a prospective cross-sectional study, smokers (n=114) and nonsmokers (n=119) were included. The Pittsburgh Sleep Quality İndex (PSQI), the Epworth Daytime Sleepiness Scale (ESS), the Sleep Hygiene Index (SHI), and the Short Form-36 quality of life scale (SF-36) were applied. Results: We found that none of the components, as well as the PSQI total score were affected in smokers compared with the nonsmoker controls (65.5% of smokers had poor sleep compared to 62.5% of nonsmokers). Although smokers tend to get out of bed at different times from day to day and do important work before bedtime (components of the SHI) more often than non-smokers, no significant differences were detected between groups in any component and SHI total score (27.91±6.72 for smokers and 29.23±8.0 for non-smokers). ESS, depression and anxiety symptoms, and SHI scores in smokers with poor sleep quality were significantly different compared with smokers that had normal sleep quality. Both PSQI and SHI scores were inversely associated with QoL parameters. Conclusions: Our results suggest that smoking by itself is not associated with poor sleep hygiene or sleep quality. It can be concluded that worse SHI and quality of sleep negatively affect QoL, depression, and anxiety in smokers.
