The technological process of composite products’ molding consists in giving them non-a reversible shape using shape-generating molding tools through polymerization of the binder at a certain temperature and pressure varying in time. The paper deals with the research of technological parameters of the most common practical method of molding products made of polymeric composite materials, pre-formed of prepregs. The mathematical model of filling with a binder of inter-fiber space of the reinforcing material for the polymeric composite material with the varying fiber packing densities, from quadratic to hexagonal one, depending on the type of reinforcing material, has been further developed. A new method for optimization of the pressure and time of composite products’ molding at the temperature of the minimum binder viscosity has been developed. The method is implemented by analytical dependencies, which establish the optimal time intervals and pressure of molding on the section of the temperature and time diagram, associated with the ability of the operating equipment (oven, autoclave) to provide the maximum possible rate of temperature rise in order to “soften” the binder in prepreg to its minimum viscosity. It is shown that energy consumption for the re-formation of the tetragonal structure of the polymeric composite material into hexagonal one is ten times higher than the costs for the tetragonal structure formation. For example, re-formation of the tetragonal structure at volume content of the binder of 0.4 into dense hexagonal structure requires 66.7 times increase in pressure. Obtained results allow establishing the economically feasible level of pressure and time of composite products’ molding while ensuring their specified quality.

Space debris is becoming an increasing threat to near space services, including satellite communications, the launching of new satellites, as well as navigation and timekeeping programs. It affects even observations of the Earth. As space around us becomes more congested, the need to track space objects and provide information about space activities is becoming increasingly critical and urgent in helping to prevent collisions or damage caused by space debris. Among the methods of tracking artificial objects are optical methods, which can provide information about the position of the selected object (positional observations), distance to the object (laser observations), as well as about the behavior of the object in orbit and its shape (photometric observations). The Astronomical Observatory of Lviv National University is equipped with a special hardware complex and software for the implementation of observations of artificial objects and can provide relevant information.

The idea of the unity of man and the Universe was developed in many philosophical and religious teachings. However, the first who scientifically substantiates it was Alfred Russel Wallace (1823—1913) — a British naturalist, traveler, geographer, biologist, and anthropologist of the XIX century. He noted that the idea of the «plurality of worlds» of Copernicus, where the Earth is one of the many planets inhabited by intelligent beings, is not supported by observations. Wallace substantiated that the possibility of the emergence of life and mind in the universe depends on many interrelated conditions. He concluded that «any planet in the solar system other than our Earth is uninhabited» and «almost as likely that no other Sun has inhabited planets». Wallace held the view that humans were the only intelligent beings and could have originated exclusively on Earth as the pinnacle of the evolution of the Universe. The researcher admitted the possibility of the existence of other worlds with other physical laws but believed that only in ours it was possible for a man to appear, and that is why our Universe arose.

Recent guidelines have recommended using high sensitivity cardiac troponin (hs-cTn) assays to triage patients with suspected acute coronary syndrome. Despite this, less sensitive point-of-care testing is often the preferred choice in majority of hospitals. The aim of this evidence-based, expert consensus is to provide guidance for healthcare professionals in understanding the role of hs-cTn, specifically its level of sensitivity and specificity as well as its practical application in the emergency department setting, particularly in resource-limited centres in Malaysia. An expert panel with clinical and research expertise in the diagnosis and treatment of acute coronary syndrome was convened. Recommendations were based on a comprehensive review of the existing literature using MEDLINE and Embase databases, alongside individual clinical experience within the regional and international context. This expert consensus provides a structured approach to using hs-cTn in the emergency department and remains the only one to date produced by a group of Malaysian experts to help guide Malaysian clinicians dealing with acute chest pain on a daily basis.

Published: May 2022

The current study aimed to assess the ovarian and uterine haemodynamics in postpartum (pp) Egyptian buffaloes and their relation to steroid hormonal levels (progesterone and estrogen). Six multiparous buffalos with normal calving were examined by using trans-rectal Doppler sonography to assess the blood flow in ipsilateral and contralateral ovarian and uterine arteries. Doppler parameters viz. peak systolic velocity (PSV), blood flow volume (BFV), resistance (RI) and pulsatility index (PI) were measured at 1st till 6th postpartum weeks. In addition, diameters (mm) of the ovarian and uterine arteries and the vascularisation area (mm2) of ovary were determined. The blood samples were collected starting from 1st week post calving and every week thereafter following each ultrasound Doppler examination for assay of progesterone and estradiol. Results indicated that PI and RI increased consistently and significantly (P<0.05) till the 6th week post calving as compared to those recorded at 1st week in ipsilateral ovarian and uterine arteries. However, the blood flow volume and peak systolic velocity in both ovarian and uterine arteries decreased gradually from 1st week till the 6th week after calving. There were very strong positive correlations between PSV and BFV, in both ipsilateral and contralateral ovarian and uterine arteries. Blood concentrations of progesterone were lower (P<0.05) during the first four weeks than those recorded at 5th and 6th postpartum weeks. This trend was reversed for blood estradiol 17-β. The results of the present investigation concluded that Doppler ultrasonography is a suitable tool for assessing changes in ovarian and uterine perfusion during the puerperium.

Published: May 2022

This study examined the relationships between diet quality, satisfaction with food-related life and life satisfaction in mother-adolescent dyads. The sample consisted of 470 mother-adolescent dyads in Temuco, Chile. Mothers and adolescents responded to the Adapted Healthy Eating Index, Satisfaction with Life Scale, and the Satisfaction with Food-related Life scale. Data was analyzed using the Actor-Partner Interdependence Model (APIM) and Structural Equation Modelling (SEM). Diet quality was associated with satisfaction with food-related life, which related to life satisfaction in mothers and adolescents. We did not find direct relationships between diet quality and life satisfaction for either dyad member. Adolescents’ diet quality negatively affected their mothers’ satisfaction with food-related life; adolescents’ food-related life was positively associated with their mothers’ life satisfaction. The mothers’ satisfaction with food-related life played a mediating role between their own diet quality and life satisfaction. Mothers and their adolescent children affect one another in their dietary patterns and life satisfaction. Child-to-mother influences on food-related experiences show that adolescents’ satisfaction with food-related life improves their own and their mothers’ life satisfaction. Interventions to promote healthy eating habits must be addressed to both mothers and their adolescent children.

Abstract: Currently the Atlantic Forest hotspot has less than 11% of its original coverage. However approximately 300 species of reptiles are known to inhabit this ecoregion, of which 34% are endemic. The creation of protected areas represents a strategy for preserving ecosystems and managing land use, and for attaining the proper management of these protected areas, information on local biodiversity is essential. Herein we provide the first list of reptile species for the Estação Ecológica and Área de Proteção Ambiental de Murici, two overlapping protected areas located in the state of Alagoas, one of the most important sets of forest remnants for the conservation of the Atlantic Forest in the northeast of Brazil. The species list was constructed based on expeditions and occasional encounters in the area between 1994 and 2022. A total of 89 reptile species were obtained during the 28 years of collection, being two species of Crocodylia, three species of Testudines and 84 species of Squamata. This richness is by far one of the greatest ever documented for the Atlantic Forest. Additionally, two species registered in the area are considered threatened according to the national list (Amerotyphlops paucisquamus and Bothrops muriciensis) and six are defined as data deficient for the assessment of their conservation status. Three species are recorded for the first time in the Atlantic Forest north of the São Francisco River: Dipsas indica, Trilepida salgueiroi and Cercophis auratus. We claim that the species list provided here will serve as a starting point for further studies in this rich reptile “hotspot” within the Atlantic Forest.

ABSTRACT The study aimed to isolate, identify, and apply in vitro tests on bacteria with autochthonous probiotic potential isolated from fifteen healthy specimens of Megaleporinus macrocephalus. The strains were selected from the intestinal tract of fish and inoculated in the Petri plate containing Sharp Man Rogosa Agar (MRS) for (48 hours at 35ºC). They were isolated based on a test of catalase, Gram stain, tolerance to different gradients NaCl (1, 2 and 3%), pH (4, 5, 6, 8 and 9) values and bile salts (2.5 and 5%), in addition to the inhibition zone against pathogens. Of the 42 strains isolated, ST1 and ST9 had higher values (p<0.05) for total viable cells (31.80±0.07 and 32.51±0.05 CFU/mL × 108) respectively. In the resistance tests, strains ST1 and ST9 presented the best results, with emphasis on ST9 in the gradients of pH, high values of bile salts and larger inhibition zones against Aeromonas hydrophila and Aeromonas jandaei. The strains with the best results in the tests, ST1 and ST9, were identified by the MALDI-TOF-MS method as Enterococcus faecium. Thus, the isolated E. faecium bacteria, may be recommended as for probiotic use in farming the M. macrocephalus.

ABSTRACT The objective of this study was to determine the effectiveness of mycotoxin management with feed additive by monitoring biochemical blood parameters, reproduction status and udder health in cows. During the first 1-12-months, the reproduction performance was assessed. The cows were fed only total mixed ration (TMR) with naturally contaminated mycotoxins (ZEN;DON;AFB1;OTA) and the cows were regarded as a control group (CG). In months 13-15, two groups were created: control (CG)(n=30) and experimental (EG)(n=60). The CG was fed with contaminated TMR and the EG was fed with the same TMR+40g/cow mycotoxins management feed additive (TMXL1000). During this period, blood indicators and udder health were studied. Beginning with months 16-24, all cows were fed with contaminated TMR+40 g/cow (TMXL1000) and regarded as the EG. The IgA concentrations in the CG decreased in the 15th month (p<0.05). The concentrations of cortisol decreased by two times (p<0.05) in the EG. Ovarian cyst treatment was more effective by 14.98% (p<0.05) in the EG than in the CG (p<0.05). The EG performed an effective (18.02%) (p<0.05) response to applied ovsynch protocol compared with the CG. According to the obtained results, it can be concluded that feed additive for mycotoxins management had a positive impact on dairy cow health.
Study on the mechanisms of Suaeda rigida polysaccharides on the heart inhibition and skeletal muscle promotion in the frog
Authors: Sha A.L. , Hao H.Y.
Published: May 2022

ABSTRACT The objectives of this study were to investigate the effects of different concentrations of Suaeda rigida polysaccharides (SRPs) on the physiological characteristics of the frog heart and gastrocnemius muscle, compare their similarities and differences, and analyze the mechanisms. CaCl2 and acetylcholine (Ach) were selected respectively to be co-incubated with the high concentration SRPs to observe the effects on the heart contraction of frog. The effects of different concentrations of the SRPs on the activities of acetylcholinesterase (A-CHE), Na+-K+-ATPase and Ca2+-Mg2+-ATPase in the isolated frog heart were detected by UV-Vis spectrophotometry. The gastrocnemius muscle was immersed in the high concentration of SRPs for 10 min, and the systolic indexes were recorded. The effects of SRPs on the Ach content and A-CHE activity at the sciatic nerve-gastrocnemius junction were determined by UV-Vis spectrophotometry and enzyme-linked immunosorbent assay (ELISA). The results showed that the SRPs had significant inhibitory effects on the contractile amplitude of isolated heart and the contractile amplitude induced by CaCl2 and Ach, respectively (P<0.01). The activity of Ca2+-Mg2+-ATPase was significantly promoted, and the activity of A-CHE was significantly inhibited (P<0.01). The contraction amplitude, contraction rate, relaxation rate of gastrocnemius muscle and the Ach content at the junction of sciatic nerve-gastrocnemius muscle were significantly increased (P<0.01), and the activity of A-CHE at the junction was significantly inhibited (P<0.01) by the SRPs. All the results suggested that the SRPs could inhibit the contraction of heart and promote the contraction and relaxation of skeletal muscle. The mechanism was related to blocking the fast INa channel, inhibiting the ICa-L and activating the M receptors of myocardial membrane and then inhibiting external Ca2+ influx, increasing Ca2+-Mg2+-ATPase activity, decreasing a-che activity.

Published: May 2022

ABSTRACT Objective: Compare the accuracy of early diagnosis of simulated internal root resorptions and external root resorption, using digital periapical radiography and cone beam computed tomography. Methods: Root resorption were simulated in extracted human teeth by demineralization with 5% nitric acid solution and 8% Sodium Hypochlorite in different periods (1 and 5 days). For the group external root resorption (n=12) composite resin cylinders were positioned on middle third of buccal surface of roots, to delimit application of demineralization substances. In group internal root resorptions (n=12) the teeth were sectioned longitudinally, and the composite resin cylinders were positioned in the middle third of root canals. The teeth were mounted in a dry mandible and evaluated by digital radiography and tomography. The images were evaluated by two examiners. Results: Analyzing the tomographic images in period of 1 day, the examiner 2 identified internal root resorptions that were not identified in radiographic images (p<0.05). No examiner was capable of diagnosing external root resorption irrespective of exam, in the group of 1 day (p>0.05). In 5 day period of induction, both exams identified internal root resorptions (p>0.05), however, the tomographic images were more effective in identifying external root resorption (p <0.05) for both examiners. Conclusion: Cone beam computed tomography was shown to be more effective than digital periapical radiography for detecting internal root resorptions with 1 day of induction. The imaginological resources used in this study were not able to early detect external root resorption.

Resumo A elevada carga da doença renal, disparidades globais no cuidado renal e desfechos ruins da insuficiência renal impõem uma sobrecarga crescente aos indivíduos afetados e suas famílias, cuidadores e a própria comunidade geral. Educação em saúde é o grau em que indivíduos e organizações têm, ou que igualmente permitem que indivíduos tenham, capacidade de encontrar, compreender e utilizar informações e serviços para tomar decisões e ações conscientes relacionadas à saúde para si e outros. Mais do que enxergar educação em saúde como um problema dos pacientes, a melhoria dessa educação depende principalmente da comunicação e educação efetiva dos profissionais em parceria com aqueles que apresentam doença renal. Para formuladores de políticas renais, educação em saúde é pré-requisito para que organizações migrem para uma cultura que coloque a pessoa no centro dos cuidados. A crescente capacidade e acesso à tecnologia oferecem novas oportunidades para melhorar educação e conscientização sobre doença renal para todas as partes interessadas. Avanços nas telecomunicações, incluindo redes sociais, podem ajudar a melhorar a educação de pessoas e provedores. O Dia Mundial do Rim declara 2022 como o ano da "Saúde dos Rins para Todos" promovendo trabalho em equipe global no avanço de estratégias para preencher a lacuna na educação e conhecimento em saúde renal. Organizações renais devem trabalhar para mudar a narrativa da educação em saúde como um problema de pacientes, para sendo responsabilidade dos profissionais e formuladores de políticas. Ao engajar-se e apoiar formulação de políticas centradas na saúde renal, planejamento de saúde comunitária e abordagens de educação em saúde para todos, comunidades renais esforçam-se para prevenir doenças renais e permitir viver bem com elas.

Una aproximación metaetnográfica a la racionalidad y emotividad en los procesos de atención y cuidado en hospitales de Latinoamérica
Authors: Moglia Brenda , Sy Anahi
Published: May 2022

Resumen Los procesos de atención y cuidado de la salud-enfermedad en los hospitales se configuran en torno a diferentes dimensiones relacionales entre los actores implicados. En las sociedades occidentales se han naturalizado a estas instituciones como espacios que suponen una estructura vertical, dominada por la racionalidad biomédica. Este artículo se basa en la revisión de la bibliografía y muestra que las prácticas de atención y cuidado involucran distintos vínculos, saberes y emociones que configuran aspectos por fuera de lo normado desde la institución. El objetivo consiste en indagar en los procesos de atención y cuidado desarrollados en los hospitales de Latinoamérica, colocando el foco en las tensiones entre la racionalidad que impone la norma y las emociones que emergen en el proceso de trabajo. Para ello se realizó una metaetnografía, que permitió sintetizar investigaciones cualitativas y producir una nueva interpretación del problema estudiado. De este modo, se conformó un corpus de 36 artículos científicos a partir de las búsquedas en las bases de la Biblioteca Virtual en Salud (BVS), PubMed, SciELO y Scopus. Los resultados muestran que las racionalidades y las emociones intervienen como dimensiones estructurales de los procesos de atención y cuidado en los hospitales.
Schools as Learning Organisations in Wales: A Critical Exploration of the International Evidence Base
Authors: Harris Alma , Elder Zoe , Jones Michelle Suzette , Cooze Angella
Published: May 2022

Within the Welsh education system, ‘Schools as Learning Organisations’ (SLOs) remains a centrepiece of current education policy. This article considers some of the key evidence base(s) that connect to and underpin the SLO model in Wales. This is not a review of the literature but rather an overview of the main empirical evidence that reinforces the SLO approach in Wales. The article highlights that there is a supportive, empirical evidence base for each of the 7 dimensions of the Welsh SLO model. It concludes, however, that more practical guidance, particularly about implementation processes, are needed to assist schools in their journey towards becoming stronger learning organisations.

Published: May 2022

The objective of this study was to evaluate the importance of various yield and nutritional characteristics for the differentiation of forage cultivars using principal component analysis (PCA). Data were obtained from an experiment conducted with a complete randomized block design (RCBD) with 6 replications. Eleven cultivars of forage grasses of the species Urochloa brizantha, U. ruziziensis, Megathyrsus maximus, Cenchrus ciliaris, Andropogon gayanus and Setaria sphacelata were evaluated. For yield characteristics, PCA revealed that the first 3 components explained 82.0% of total variation between forage cultivars. Similar results were observed for nutritional characteristics with the first 3 components explaining 91.4% of total variation in leaf chemical composition and 83.8% of variation in stem chemical composition. Variables that contributed most to discrimination between forage cultivars were: number of tillers per plant; number of leaves per plant; median leaf width; stem dry matter yield; leaf:stem ratio; % dry matter, % crude protein (CP) and % neutral detergent fiber of leaves; and % CP, % ether extract and % acid detergent fiber of stems. PCA was effective in identifying the key parameters that need to be measured in evaluating grass species and allowed a reduction in the number of yield and nutritional characteristics to be assessed in experiments designed to evaluate forage cultivars. This reduced both the workload and the costs involved while still allowing valid conclusions.

VOC and VOI (SARS-Cov-2) identification by Sanger Sequencing v2
Authors: Ceschini Laís
Published: May 2022

The method hereby described is an update of a rapid and accessible protocol based on Sanger sequencing that is able to discriminate the main SARS-CoV-2 VOCs (Variants of Concern) and VOIs (Variants of Interest), according to each characteristic mutational signature at the Spike receptor binding domain (RBD) and an additional mutational profile of the N-terminal domain (NTD) of the Spike protein. Although this approach does not substitute whole-genome sequencing, in a scenario that combines the rapid spread of new VOCs around the world with supply shortages and lack of technical infrastructure, it represents a powerful tool that allows a broader network of laboratories to perform molecular surveillance of SARS-CoV-2 VOCs, improving its capacity to report more results within in a timely manner.
Human Pancreas Processing v1
Authors: Chen Jing , J Butfiloski Edward , E Mathews Clayton , Campbell-Thompson Martha
Published: May 2022

The pancreas is a combined endocrine and exocrine organ and is uniquely positioned in the upper abdomen between the stomach (posterior and superior margins), duodenum (proximal or medial), spleen (distal or lateral) and bowel (anterior and inferior). The normal pancreas is shaped as for a pistol with the proximal head region attached to the duodenum and comprising the handle while the distal head/neck, body and tail regions form the barrel. The fluid tone of the soft pancreas makes it difficult to maintain its in vivo 3D shape once trimmed of attached duodenum, spleen and peripancreatic soft tissues. The purpose of this protocol is to describe pancreas collection and processing procedures suitable for single cell mapping. We describe the process of dividing the entire pancreas into sequential cross sections that are subsequently photographed, weighed and processed for the wide range of technologies used in HuBMAP and other programs. Steps describe processing samples to fixed samples for paraffin embedding, optical clearing, or fixed frozen blocks as well as unfixed samples for fresh frozen blocks. Methods are based on those established for the Network for Pancreatic Organ donors with Diabetes program as previously published with minor modifications.

INTRODUCTION: In the first half of the 20th century, Icelandic doctors and teachers began documenting the health of school children, believing that physical measurements were important to monitoring physical development. The measurements could also be used for comparison in other areas and for reasearch. At the Reginonal Archives of Skagafjordur, rare data about the physique of children in Saudarkrokur in 1912–1953, measured by Jon Th. Bjornsson, is preserved. MATERIAL AND METHODS: Height, weight, grip strenght, thorax expansion and tidal volume were measured twice in 2018–2019 on 7–15-year-old children in elementary schools in Saudarkrokur and Varmahlid. These measurements were compared with similar measurements from 1912–1953. RESULTS: Children in 2018–2019 at ages 7–15 years were significantly taller, heavier, with greater thorax expansion and tidal volume than their peers in 1912–1953 (p<0,001–0,037). Children in 2018–2019 at ages 7–14 years had significantly higher body mass index than their peers in 1912–1953 (p<0,001–0,027). If adjusted for height and weight in thorax expansion and tidal volume measurements, similar results were found. Children in 2018–2019 had significantly less grip strength than their peers in 1912–1953 at ages 7 and 9–12-years when adjusted for height and weight (p<0,001–0,025). There was significant development in the physique of children over the years 1912–1953 in most measurements and age groups (p<0,001–0,040). CONCLUSIONS: A significant increase in measured factors in 2018–2019 compared to 1912–1953 can possibly be attributed to improved quality of life.
Functional recovery after first episode psychosis rehabilitation in an early intervention psychosis center in Iceland

BACKGROUND: Because of the early onset and disabling symptoms of schizophrenia spectrum disorders many individuals with these disorders are unemployed from an early age and disability pension rates are high. The aim of this study was to assess functional recovery and identify vocational predictors among young first episode psychosis patients registered in an early intervention psychosis center in Iceland in 2010-2020. METHODS: The study is a retrospective cohort study based on the medical records of those who were discharged from Laugaras, the only early intervention psychosis program in Iceland after six months or longer rehabilitation in 2010-2020 (n=144). Univariate and multivariate logistic regression was used to identify vocational predictors. RESULTS: 75% of patients were unemployed at admission to the early intervention center but over half of the patients were employed or in school at discharge. Vocational rehabilitation was the strongest vocational predictor (OR 13.93, 95% CI 3.85-63.89). Other vocational predictors were those that reflect a disabling psychiatric disorder and social functioning before the onset of early intervention. 66% of patients had a history of cannabis use which had a negative impact on employment and education at discharge. CONCLUSIONS: In spite of intensive rehabilitation at an early intervention center, almost half of the patients were neither employed nor in school at discharge. The strongest vocational predictor was vocational rehabilitation which was also one of few vocational predictors that can be influenced by admission to an early intervention psychosis center. It therefore seems important to ensure that effective vocational rehabilitation is readily available at early intervention psychosis centers.
Vitreous function and intervention of it with vitrectomy and other modalities

The vitreous body, the largest intraocular component, plays a key role in eye development, refraction, cell barrier function, oxygen metabolism and the pathogenesis of assorted diseases. Age, refraction and systemic diseases can cause vitreous metabolic abnormalities. With the continuous development of vitrectomy techniques and equipment, vitreous injections and vitrectomies have increased over the recent decades. However, the normal oxygen tension gradient in the vitreous helps to protect the lens and anterior chamber angle from oxidative stress damage, whereas the increased vitreous oxygen tension around lens and the trabecular meshwork after vitrectomy. It may lead to postoperative nuclear cataract and increase the risk for glaucoma. As a conventional procedure, scleral buckling holds several advantages over vitrectomy in selected cases. This review raises concerns regarding the function of the vitreous and encourages conducting vitreous interventions prudently if it is possible.
