Fucoxanthin from brown algae has potential as a promising functional food component.
However, fucoxanthin is less stable under high temperature and light exposure. The
purpose of this study was to analyse the effect of stevia and cacao butter in increasing
the stability of Sargassum polycystum C. Agardh extract containing fucoxanthin and its
application as a snack bar. Brown algae, S. polycystum, was extracted using 96% foodgrade ethanol. Antioxidant activity and stability assay were performed using the 2,2-
Diphenyl-1-Picrylhydrazyl (DPPH) method. Antioxidant activity of both, extract (E)
and extract + stevia (ES), was found to decrease with time. Meanwhile, cacao butter
was able to maintain extract’s stability without any significant difference when
compared to extract alone. A combination of extract, stevia, and cacao butter (ESC)
were found to be able to maintain antioxidant stability. Formulation of a snack bar with
cacao butter and 1% stevia were more preferred by the panellists when compared to the
other formulations. This study reports that cacao butter and 1% stevia is able to
maintain antioxidant stability and improve the economic value of S. polycystum, one of
them through the formulations of the snack bar.

Published: November 2021

This study aimed at investigating the prevalence of different mould genera and total
aflatoxins (AFTs) content in the retailed frozen chicken breast, thigh, and giblets,
including wings, livers, and gizzards. Furthermore, the estimated daily intakes (EDI) of
AFTs were calculated. Aflatoxin-related cancer risks among Egyptian adults and children
were further assessed using the margin of exposure (MOE) approach. The obtained results
indicated mould contamination of the examined chicken breast, thigh, wings, livers, and
gizzards at 40%, 30%, 25%, 70%, and 60%, respectively. Aspergillus spp. and Penicillium
spp. were the most predominant mould genera among the examined samples. Further
identification of the isolated Aspergilli revealed that Aspergillus niger and Aspergillus
flavus were the dominant Aspergillus spp. AFTs were detected only in 40% and 25% of
the examined liver and gizzard samples, respectively. Positive correlations between AFTs
and total mould counts in both livers and gizzards were observed. Calculation of the EDI
and MOE of AFTs via consumption of chicken livers and gizzards revealed that excessive
consumption of such products represents a potential risk, particularly among children.
Therefore, it is highly recommended to adopt strict hygienic measures during the
processing and storage of chicken carcasses and reduce the daily intake of chicken livers
and giblets.

Objective ‒ to develop a technique of triple antiembolic protection with the simultaneous use of proximal antiembolic protection systems, distal antiembolic filters and two-layer micromesh carotid stents for carotid stenting of ultraembolic hazardous carotid stenosis. Evaluate its effectiveness and safety.Materials and methods. Since 2016, 23 carotid stenting of ultraembolic hazardous carotid stenoses has been performed using the technique of triple antiembolic protection (proximal antiembolic protection systems, distal antiembolic filters and two-layer micromesh carotid stents). All patients had symptomic stenosis: transient ischemic attacks in a certain carotid pool (n = 7), ischemic strokes (n = 16). The age of patients was from 57 to 84 years. Men prevailed among patients (n = 15). Postoperative follow-up included magnetic resonance imaging (MRI) of the brain on the first or second day after surgery with T2*, FLAIR and DWI sequences to determine the presence of «fresh» embolic ischemic foci and to exclude hemorrhagic complications. After 6 months, a control clinical examination, computed tomography or MRI of the brain, ultrasound angioscanning of the main arteries of the head were performed.Results. In all patients the patency of the carotid arteries was completely restored, and in the early postoperative period, no clinical signs of recurrent ischemic brain damage were detected in any of the cases. No signs of plaque prolapse through the stent were detected in any case. A significant amount of atheromatous debris was in 11 cases when aspirated on an external filter. In 3 cases, emboli were also detected in the distal protection filter. This fact indicates that the joint use of distal and proximal antiembolic systems reliably protects against the risk of embolism in such cases. According to MRI on the 1st or 2nd day there were no signs of «fresh» subclinical embolic ischemic foci, as well as hemorrhage. In 20 patients who underwent a follow-up examination, no signs of restenosis in the stent were recorded in any case, as well as repeated ischemic strokes. In 7 cases where the plaque had an ulcer, the ulcer resolved under the stent. Three patients are expected for a follow-up examination. According to the remote survey, these patients do not have new ischemic brain lesions. The effectiveness of the technique of triple antiembolic protection for the treatment of patients with subtotal ultraembolic hazardous carotid stenosis is indicated by the absence of clinical and neuroradiological signs of recurrent ischemic lesions.Conclusions. The technique of triple antiembolic protection for the treatment of patients with subtotal ultraembolic hazardous carotid stenoses is safe and highly effective. It is the improvement of carotid stenting results in this most dangerous group that gives reason to think about revealing the advantages of carotid stenting over carotid endarterectomy in general.

Objective ‒ to analyze the results of surgical treatment of cerebellar astrocytomas in young children, to establish the factors that determine the prognosis of the course of the disease.Materials and methods. The results of surgical treatment of 112 children with cerebellar astrocytoma, who were operated in Romodanov Neurosurgery Institute of NAMS of Ukraine in 1980‒2019; 59.8 % were boys, 40.2 % were girls. The age of children ‒ from 3 months to 3 years. Removal of the tumor was performed in 106 patients: in 58 ‒ totally, in 31 ‒ subtotally, in 16 ‒ partially, in 1 ‒ biopsy. Diffuse differentiated astrocytoma (low-grade (II)) was detected in 94 (83.9 %) patients, poorly differentiated diffuse astrocytoma (high-grade (III)) ‒ in 18 (16.1 %). In the cerebellum astrocytomas in 77 (68.7 %) cases were located in the midline. In 59 (52.7 %) cases astrocytomas had a cystic component, in 53 (47.3 %) cases were solid ones. Postoperative mortality over 30 years of observations was 15.2 %. Results. It was found that survival rates in the early postoperative period were statistically (p = 0.03) better in cases of total tumor resection compared with patients after with subtotal resection. In patients with diffuse differentiated astrocytoma of the cerebellum, the average duration of follow-up was 6.7 years, a good quality of life was noted in 39.4 % of patients. In the long-term follow-up period, 7.3 % of children died. In patients with poorly differentiated diffuse astrocytoma of the cerebellum, the average duration of follow-up was 4.3 years, while a satisfactory quality of life was observed in 68.0 % of patients, a poor quality in 22.0 %, and a vegetative state in 10.0 % of children. In the long-term period, 20.0 % of children died. Microscopic features of cerebellar astrocytomas are their expansive-infiltrative nature of distribution and the presence of zones of neoangiomatosis.Conclusions. It was revealed that the degree of differentiation of diffuse cerebellar astrocytomas and the radicality of their removal correlates with the quality and life expectancy of patients. The tendency of the influence of the degree of malignancy of astrocytomas on the indicators of general and reccurence-free survival of children of the younger age group was noted.

Authors: Kaminskyi A.A.
Published: November 2021

Objective ‒ to analyze data of patients with hypertensive supratentorial hemorrhages who were hospitalized in Kyiv Emergency Hospital in 2019‒2020.Materials and methods. We analyzed data of 232 patients who were treated for hypertensive intracerebral hemorrhage at the Kyiv Emergency Hospital in 2019‒2020. Patients were included regardless of admission status and chosen treatment tactics (surgical, medical). The study did not include patients with subtentorial hemorrhage, patients with tumor hemorrhage, arteriovenous malformations, aneurysms, angiomas, ischemic and mixed strokes.Results. Among patients males are predominated (149 (64 %)). The average age of patients was 60 years (group of men ‒ 56 years, group of women ‒ 69 years). 77 (33 %) patients were delivered in a comatose state (GCS ≤8 points), 36 (16 %) were in a coma (GCS 9‒12 points), 81 patients were in a state of stupor (GCS 13‒14 points), in a clear mind ‒ 31 (13 %). In 7 (3 %) cases it is impossible to determine the level of consciousness (in patients with seizures or after the introduction of sedative drugs before admission to hospital). 85 patients were operated (surgical activity ‒37 %), who underwent 97 surgical interventions. The overall mortality was 42 %, postoperative mortality ‒ 43 %. Patients who had a compression-dislocation syndrome were operated on. Mortality in the group of patients admitted in a coma mortality was 85 % regardless of the method of treatment.Conclusions. Hemorrhagic strokes predominate in men, due to lifestyle and uncontrolled hypertension in patients. The results of treatment of patients with hypertensive intracerebral hemorrhage indicate the need for early hospitalization, early CT, differentiated approache to surgical removal of hematomas (lobar, lateral with dislocation syndrome), intensive care in patients in a comatose state, even with massive hemorrhages. The results of hypertensive intracerebral hemorrhage depend on the location of the hemorrhage, the severity of the patient’s condition, the timing of hospitalization in specialized stroke departments, the dynamics of cerebrovascular disorders (completed stroke and stroke in development).

Objective ‒ to highlight the high probability and features of neurological complications in patients with COVID-19 pneumonia.Materials and methods. A retrospective cohort study was done of 57 patients with COVID-19 pneumonia who were treated at the COVID-location of the Department of Vascular and Minimally Invasive Neurosurgery and Neurology of the Clinical Emergency Hospital of Lviv in the period from June 29 to September 28, 2020 (91 day).Results. Out of the 57 patients 14 (24.6 %) were selected by prospective analysis that had a clear association between COVID-19 pneumonia and neurological complications. Neurological complications of COVID-19 were manifested as ischemic stroke in 57.1 % of patients, encephalopathy with convulsions and without seizures ‒ in 35.7 %, polyneuropathy with tetraparesis, secondary purulent-inflammatory lesions of the spine ‒ in 7.2 %. Neurological complications occurred on average (20. 4 ± 6.1) days after the onset of the disease.Conclusions. Lesions of the spine and structures in the spinal canal after coronavirus infection had a significant spread along the axis of the spine and severe course. The largest (57.1 %) was the proportion of ischemic stroke in the structure of neurological complications of COVID-19, which indicated the severity of the coronavirus infection and its aggressive effect on the nervous system. The effectiveness of treatment of COVID-19 neurological complications depends on the urgency of hospitalization of patients, as evidenced by the correlation between favorable treatment outcomes and the time from disease onst to admission to either therapeutic (r = + 0.37) or neurological department (r = +0.32).

Published: November 2021

TB is still a public health problem throughout the world where Indonesia is a country that has the third largest number of TB sufferers after India and China. Self-care by patients and families during the treatment process was the key to healing pulmonary TB. Using a quasi-experimental method, this study aims to improve the ability of self-care for pulmonary TB patients through intervention by “TB Mataho” health cadres. Most of the self-care capacity of pulmonary TB patients with pre-test results were sufficient, in the treatment group (75.2%) and the control group (62.5%). The post-test results for the treatment group were in the good category (53.1%) and the control group was in the sufficient category (59.4%). The results of the Paired Samples Test analysis in the treatment group obtained a value of p = 0.001 (p <0.05), which means that there was a significant difference in self-care capacity of pulmonary TB patients before and after treatment, as well as the results of the Independent Samples Test analysis, the p value was obtained. 0.030 (p <0.05) which means that there was a significant difference in the post-test results in the treatment group and the control group. Researchers recommend that pulmonary TB survivors who have a basic education of secondary and above can be trained to become health cadres and share their successful experiences with pulmonary TB patients who are still undergoing treatment programs.

Adolescence is a developmental stage from the transition to adulthood. A cognitive problem that affects adolescence namely the lack of knowledge about reproductive health. The purpose of this study was to explain the effectiveness of health education using audio-visual methods on students' knowledge and attitudes about adolescent reproductive health during the COVID-19 pandemic. This research uses a quasi-experimental design. The results obtained from the 75 respondents who filled out the questionnaire showed that the attitude of the students on the pre-test score was 60,00 and the post-test was 63,45, whereas the students' knowledge on the pre-test score was 15,89 and the post-test is 17,20. From the results of the research carried out with the Wilcoxon test that the Asymp. Sig (2-tailed) is worth 0,0001 where the value is less than <0.005, therefore the hypothesis was accepted. Using audiovisual media is that it will add more real material content and will increase memory retention due to media that is much interesting and easy to remember by the individual, factors that can influence knowledge and attitudes related to reproductive and sexual health in adolescents are knowledge, attitudes and the individual's environment in processing the information obtained. Therefore there is a significant effect of health education with audiovisual methods on increasing the knowledge and attitudes of adolescents related to reproductive and sexual health.

El nuevo coronavirus ha planteado una serie de cambios que afectan a diversos sectores de nuestra sociedad. En el sector de la educación, las medidas de protección contra el Covid-19, han llevado a los países del mundo a la suspensión obligatoria de las clases en todos los niveles de educación. Con la persistencia de la pandemia, muchos países han tenido que decidir pasar de una educación presencial tradicional a una educación a distancia, lo cual se ha convertido en un verdadero reto para garantizar a los estudiantes la prosecución de la educación. El objetivo de la presente investigación es plasmar las generalidades de la educación en todos sus niveles ante la situación de la pandemia del Covid – 19 y los retos que ha generado. Desarrollado de la siguiente manera: paradigmas de la educación presencial y a distancia, cambio del paradigma tradicional, consecuencias y la educación superior y el Covid - 19. El modelo de investigación es una revisión de tipo documental bibliográfico. Las reflexiones y aprendizajes que ha dejado el Covid – 19 al sistema educativo se deben fundamentar en la consideración de las desigualdades económicas y digitales entre los países del mundo. El futuro inmediato, incierto ante la situación persistente de la pandemia, requiere estrategias capaces de combinar varias tecnologías de manera que la educación sea accesible a todos los estudiantes, en especial a los de los países más pobres que se encuentran desde antes de la pandemia en desventaja. El Covid – 19 ha dejado en evidencia que no todas las regiones del mundo se encuentran preparadas para asumir una educación completamente a distancia. La falta de estructuras tecnológicas, de acceso a internet, de adaptación de los currículos educativos, entre otras, constituyen algunos de los nuevos retos educativos ante la experiencia en esta pandemia.
Damaging, Destroying and Rebuilding of Watermills and Windmills in the Late-Medieval State of the Teutonic Order in Prussia
Authors: Kubicki Rafał
Published: November 2021

Młyny wodne i wiatraki stanowiły ważny element infrastruktury miast i wsi w późnym średniowieczu – zapewniały bowiem możliwość przemiału odpowiedniej ilości zbóż i słodu potrzebnych do produkcji dwóch najważniejszych produktów spożywczych: chleba i piwa. W związku z tym były narażone na zniszczenia w czasie toczonych wówczas konfliktów zbrojnych. Oczywiście uszkodzenie i niszczenie młynów i wiatraków następowało też z przyczyn naturalnych: czynników atmosferycznych (wezbrania wody, przerwania grobli w wypadku młyna wodnego czy też silnego wiatru w wypadku wiatraka). Problem uszkodzenia, niszczenia, ale i odbudowy młynów wodnych i wiatraków został tu przedstawiony na przykładzie władztwa zakonu krzyżackiego w Prusach w późnym średniowieczu (w XIV i pierwszej połowie XV w.). Obok kwestii prawnych i gospodarczych związanych z tym zjawiskiem podjęto próbę określenia skali i rejonizacji występowania młynów pustych, zniszczonych lub tylko opuszczonych, uszkodzonych i później nieodbudowanych. W pierwszej połowie XV w. nastąpił dość wyraźny spadek wysokości ogólnego czynszu z młynów, jaki pobierał zakon krzyżacki. Wynosił on w wypadku komturstwa ostródzkiego 12%, bałgijskiego 7–8%, a elbląskiego 4%. Znacznie gorzej było natomiast na terenie ziemi chełmińskiej i na Pomorzu Gdańskim, które znajdowały się w zasięgu intensywnych działań wojennych, toczonych w ramach kolejnych konfliktów z Polską. W komturstwie kowalewskim spadek czynszu wyniósł 40%, brodnickim 25%, a w tucholskim aż 64%. Wprawdzie nie dysponujemy wykazami obejmującymi w tym czasie całe władztwo zakonu krzyżackiego w Prusach, jednak nawet na podstawie zachowanych przekazów można stwierdzić, że działania powodowane wojnami prowadzonymi przez zakon z Polską w pierwszej połowie XV w. przyniosły ogromne zniszczenia struktur gospodarczych na wsi, w tym i znajdujących się tam młynów wodnych i wiatraków. Nie wszystkie z tych urządzeń zostały później odbudowane, po części z nich zostały jedynie wzmianki w starszych wykazach czynszowych sporządzanych przez urzędników zakonu krzyżackiego.

Geosynthetic Encased Column: comparison between numerical and experimental results
Authors: Alkhorshid Nima , Araújo Gregório , Palmeira Ennio
Published: November 2021

The use of granular column is one of the ground improvement methods used for soft soils. This method improves the foundation soils mechanical properties by displacing the soft soil with the compacted granular columns. The columns have high permeability that can accelerate the excess pore water pressure produced in soft soils and increase the undrained shear strength. When it comes to very soft soils, the use of granular columns is not of interest since these soils present no significant confinement to the columns. Here comes the encased columns that receive the confinement from the encasement materials. In this study, the influence of the column installation method on the surrounding soil and the encasement effect on the granular column performance were investigated using numerical analyses and experimental tests. The results show that numerical simulations can reasonably predict the behavior of both the encased column and the surrounding soil.
Experimental evaluation of the classical and alternative consolidation theories in predicting the volumetric change of contaminated and non-contaminated soil
Authors: Lemos Moisés , Guimarães Lucas , Cavalcante André
Published: November 2021

Several regions in Brazil and the world suffer from the presence of collapsible soils. The development of theories for understanding the phenomenon is significant because the increase of water content is associated with several reasons (e.g., precipitation, rupture of sewage, and water systems). Although some theories explain the behavior of various types of soils, they fail to explain collapsible and structured soils. In this research, an alternative interpretation of the consolidation theory is verified and calibrated for collapsible soil. The alternative model was applied to experimental data from a latosol from southeastern Brazil, and comparisons with the classical theory showed a difference in the saturated hydraulic conductivity of around 100 times. The observation showed promising results compared with the saturated hydraulic conductivity of the field (Guelph Permeameter). Furthermore, consolidation tests verified the collapse potential, the variation of consolidation coefficient and saturated hydraulic conductivity, and the total settlement prevision due to the presence of bleach and washing powder.

Data on students who participated in the Bebras Challenge at Maranatha Bebras Bureau indicates increasing numbers from 2016 until 2020. This paper describes a service learning for mentoring teachers and students in the Bebras Challenge, which was held in the pandemic year 2020. Teacher mentoring was using a service learning approach, where the lecturers provided training to the teachers and then the teachers would share their knowledge back to their students. There were advantages and disadvantages of the execution during the pandemic. Although in a distance learning condition, teachers and students were still enthusiastic to participate in Bebras Challenge. The number of students who followed the 2020 Bebras Challenge nearly five times compared to 2019 in the Maranatha Bebras Bureau. The scores of elementary school students who followed the challenge showed very good results. On the other side, the results of junior and senior high school students were not as good as the scores of elementary school students.
Les Germanies en la historiografia i la literatura: una visió pendular
Authors: Escartí Vicent
Published: November 2021

L’article fa un recorregut sobre el ressò i el tractament que ha merescut la revolta de les Germanies en la historiografia i la literatura en els últims cinc-cents anys i, de manera particular, en els últims dos segles. La valoració de la revolta ha anat canviant al llarg del temps, d’acord amb les preocupacions de cada època, però també amb la perspectiva política i ideològica dels autors. Enfront de la visió eminentment negativa de les cròniques coetànies al moviment i dels historiadors més conservadors i reaccionaris de la Restauració i el franquisme, els escriptors liberals i romàntics de la primera meitat del segle XIX, els intel·lectuals progressistes dels anys de la Segona República i els autors –historiadors i escriptors– valencianistes i antifranquistes en destacaren el caràcter antisenyorial i modern. El text es tanca amb un breu esment a l’aportació acadèmica més recent.
«Pel seu estament, condició i qualitat»: la representació de l’estament en la Mallorca de la modernitat
Authors: Escartí Vicent
Published: November 2021

Les famílies benestants de Mallorca van demostrar al llarg dels segles de la modernitat preocupació per la seva representació com a estament. La distinció entre grups socials s’havia de fer patent a través de certs elements que deixessin clara, de manera visible, la pertinença a cada un dels estaments socials existents. Els requisits estamentals (vestimenta, servei o educació) tenien sentit quan eren visibles ja que permetia diferenciar els grups privilegiats de la resta, de manera que es van convertir en una obligació per a aquells que s’havien de distingir. No bastava ser privilegiat, calia aparentar-ho. Aquesta situació provocà l’existència de peticions d’assistència pecuniària per tal de seguir els mandats socials de l’estament. Incomplir-los podia suposar que la resta de la societat infravalorés la seva identitat. A partir d’aquesta consideració, l’economia d’aquestes famílies podia arribar a passar a un segon pla.
El tòpic de la bonaventura de la gitana en dues poesies de la Guerra de Successió
Authors: Escartí Vicent
Published: November 2021

El present article recupera, edita i estudia dues cançons de la Guerra de Successió que elaboren un mateix tòpic: el de la gitana que diu la bonaventura a dos joves a partir de la lectura del palmell de la mà. Els joves són els dos pretendents a la corona espanyola, Felip d’Anjou i Carles d’Àustria. Primer, es repassa breument la tradició del motiu folklòric de la bonaventura de la gitana en la pintura i la literatura del barroc, i s’analitza quins elements d’aquest motiu es fan presents en l’elaboració de cada un dels poemes. Després es compara el contingut narratiu i ideològic dels dos textos, s’observa com el to humorístic del poema dedicat a Felip contrasta amb el to encomiàstic del text de Carles i s’estableix que els dos s’han de datar a l’estiu de 1707.

El pensament d’Ausiàs March, que ara poden consultar els interessats i els investigadors, és el nou estudi sobre la poesia del nostre cavaller més gran del xv. Així, sota l’edició d’Anna Alberni, Lola Badia i Raffaele Pinto, tots tres especialistes de l’obra marquiana, la Reial Acadèmia de Bones Lletres de Barcelona publica, en aquest manual, una selecció de deu ponències presentades en el Congrés Internacional de Barcelona, celebrat el passat mes de desembre de 2018. El congrés, amb el mateix títol que el llibre que ací ressenyem, va tractar de reflexionar sobre la figura del poeta del segle d’or de la literatura catalana, més com a pensador que com a creador, més com a filòsof que com a autor líric.

Adolf Piquer Vidal La identitat narrativa valenciana en el segle xx
Authors: Escartí Vicent
Published: November 2021

La identitat valenciana al segle xx ha estat un tema complex i de gran producció als estudis catalans contemporanis. La posició excèntrica del País Valencià respecte a la resta del territori de parla catalana —que a més inclou territoris originàriament castellanoparlants i una forta castellanització dels nuclis urbans—, la mancança d’un entramat cultural fort com bé podíem trobar al Principat a principis de segle o les posicions reaccionàries d’alguns sector secessionistes han marcat sovint el full de ruta d’un món laberíntic.
Problemas con la crítica de Fodor y Lepore al holismo semántico de Davidson
Authors: Arango Julián
Published: November 2021

El objetivo de este artículo es problematizar las críticas que hacen Fodor y Lepore en Holism: a shopper’s guide a la teoría holista propuesta por Donald Davidson. Para hacerlo, primero se hará una exposición de la teoría davidsoniana y se expondrán tres de las críticas hechas por Fodor y Lepore: (1) la composicionalidad es necesaria para evitar los enunciados-W; (2) la condición epistemológica de un intérprete radical es problemática; (3) el principio de caridad no tiene ningún uso en la teoría del significado, entonces no se puede derivar una conclusión holista de este principio. Una vez claras las críticas de Fodor y Lepore, se argumentará por qué no tienen un fundamento fuerte y se señalarán alguno problemas que quedan por resolver.
