Modulation of hematopoiesis by protozoal and helminth parasites
Authors: Cunningham Kyle , Mills Kingston
Published: December 2022

During inflammation hematopoietic stem cells (HSCs) in the bone marrow
(BM) and periphery rapidly expand and preferentially differentiate into
myeloid cells that mediate innate immune responses. HSCs can be directed
into quiescence or differentiation by sensing alterations to the
hematopoietic niche, including cytokines, chemokines, and
pathogen-derived products. Most studies attempting to identify the
mechanisms of hematopoiesis have focused on bacterial and viral
infections. From intracellular protozoan infections to large
multicellular worms, parasites are a global health burden and represent
major immunological challenges that remain poorly defined in the context
of hematopoiesis. Immune responses to parasites vary drastically, and
parasites have developed sophisticated immunomodulatory mechanisms that
allow development of chronic infections. Recent advances in imaging,
genomic sequencing and mouse models have shed new light on how parasites
induce unique forms of emergency hematopoiesis. In addition, parasites
can modify the hematopoiesis in the BM and periphery to improve their
survival in the host. Parasites can also induce long-lasting
modifications to HSCs, altering future immune responses to infection,
inflammation or transplantation, a term sometimes referred to as central
trained immunity. In this review, we highlight the current understanding
of parasite-induced hematopoiesis and how parasites target this process
to promote chronic infections.
Reproductive height, not vegetative height, determines the loss of clonal grasses with nitrogen enrichment in a temperate grassland
Authors: Chen Xu , Lu Haining , Ren Zhengru , Zhang Yuqiu , Liu Ruoxuan , Zhang Yunhai , Han Xingguo
Published: December 2022

Tall clonal grasses commonly display competitive advantages with
nitrogen (N) enrichment. However, it is currently unknown whether their
height is derived from the vegetative or reproductive module. Moreover,
it is unclear whether the height of the vegetative or reproductive
system regulates the probability of extinction and colonization, and
determines species richness (frequency). In this study, the impacts on
clonal grasses were studied in a field experiment employing two
frequencies (twice a year or monthly) crossed with nine N addition rates
in a temperate grassland. We found that the N addition decreased species
frequency and increased extinction probability, but did not change the
species colonization probability. A low frequency of N addition
decreased species frequency and colonization probability, but increased
extinction probability. Species reproductive height is the best index to
predict the extinction probability of clonal grasses in N-enriched
conditions relative to the vegetative height, average height, and
species biomass. No significant relationships were detected between
plant height and species colonization probability. The low frequency of
N addition may overestimate the negative effect from N deposition on
clonal grass diversity, suggesting that a higher frequency of N addition
is more suitable in assessing the ecological effects of N deposition.
Moreover, this study illustrates that reproductive height, not the
vegetative height, was associated with the clonal species extinction
probability under N-enriched environment.
LIDERANÇA, BEM-ESTAR NO TRABALHO E O DARK TRIAD: ANÁLISE DA PERCEPÇÃO DE COLABORADORES BRASILEIROS
Authors: Figueredo D'Souza Márcia , Roux Valentini Coelho César Ana Maria
Published: December 2022

O estudo objetiva a análise da influência dos traços de personalidade do Dark Triad em líderes sobre o bem-estar no trabalho de colaboradores. Para tanto, foi aplicado um survey com 268 colaboradores brasileiros. A estatística descritiva, o teste de hipóteses, as regressões múltipla e logística foram aplicadas. Os resultados evidenciaram que os colaboradores percebem seus líderes com traços narcisistas. Quanto ao bem-estar no trabalho, os colaboradores exibiram maior sentimento de realização no trabalho. As dimensões do bem-estar relativas aos afetivos positivos, negativos e de realização, mostraram-se diferentes na presença de líderes com traços maquiavélicos e psicopáticos. Os três traços associaram-se positivamente às emoções e aos humores negativos no ambiente laboral e negativamente aos afetos positivos e de realização no trabalho. Quanto mais fortes os traços maquiavélicos, maior a propensão para afetos negativos e menor propensão para afetos positivos e de realização. Os resultados oportunizam a reflexão sobre as ações de líderes com traços elevados da tríade sombria que interferem nos sentimentos e emoções positivas e impactam nas perspectivas de realização profissional dos colaboradores. Suscita o debate sobre os desdobramentos comportamentais de líderes ricos desses traços no ambiente laboral no período de crise pandêmica, haja vista o impacto direto na produtividade organizacional e saúde mental dos colaboradores. Ademais, implicam um olhar mais cuidadoso nos ambientes educacionais e programas de desenvolvimento de competências em liderança, com vistas a promover a empatia, busca de altruísmo e de valores de orientação para a vida, que considerem a valorização dos grupos e o bem-estar geral.

Nanosized multi-doped ceria with composition
Ce0.8Nd0.0025Sm0.0025Gd0.005Dy0.095Y0.095O2-? (CNSGDY) as perspective solid
ionic conductor was obtained by modified glycine-nitrate procedure (MGNP)
and room temperature self-propagating reaction (SPRT). The pressed pellets
of both powders were sintered at 1550?C for 2 h in an air atmosphere. The
obtained sintered samples were characterized by XRPD, Raman spectroscopy,
FESEM, EDS and EIS methods. Despite a high temperature of sintering, XRPD
and FESEM analyses of the samples confirmed appropriate dimensions of grains
with fluorite structure. Overall concentration of introduced dopants (x =
0.2) in the structure of CeO2 after the sintering process was confirmed by
EDS analysis. After sintering, Raman spectroscopy confirmed retention of the
oxygen vacancies in the ceria lattice, which is in accordance with the
improvement of ionic conductivity of solid ionic conductors. The highest
value of total conductivity was obtained for the sintered MGNP sample at 700?C (4.22 ? 10?2 S cm?1), with the corresponding activation energy of 0.26
eV.
The effect of Glucagon-Like Peptide-1 Receptor Blockade on glucagon-induced stimulation of insulin secretion
Authors: Farahani Rahele A. , Egan Aoife M. , Welch Andrew A. , Laurenti Marcello C. , Cobelli Claudio , Man Chiara Dalla , Vella Adrian
Published: December 2022

Data from transgenic rodent models suggest that glucagon acts as an insulin secretagogue by signalling through the Glucagon-Like Peptide-1 Receptor (GLP1R) present on β-cells. However, its net contribution to physiologic insulin secretion in humans is unknown. To address this question, we studied non-diabetic individuals in 2 separate experiments. Each subject was studied on 2 occasions in random order. In the first experiment, during a hyperglycemic clamp, glucagon was infused at 0.4ng/kg/min, increasing by 0.2ng/kg/min every hour for 5 hours. On one day exendin-9,39 (300pmol/kg/min) was infused to block GLP1R, while on the other saline was infused. The insulin secretion rate (ISR) was calculated by nonparametric deconvolution from plasma concentrations of C-peptide. Endogenous glucose production (EGP) and glucose disappearance (Rd) were measured using the tracer-dilution technique. Glucagon concentrations, by design, did not differ between study days. Integrated ISR was lower during exendin-9,39 infusion (213 ± 26 vs. 191 ± 22 nmol per 5 hr, saline vs. exendin-9,39 respectively, p = 0.02). In the separate experiment, exendin-9,39 infusion, compared to saline infusion, also decreased the β-cell secretory response to a 1mg glucagon bolus. These data show that in non-diabetic humans, glucagon partially stimulates the β-cell through GLP1R. 
Mitochondrial genome-encoded long noncoding RNA and mitochondrial stability in diabetic retinopathy
Authors: Kumar Jay , Mohammad Ghulam , Alka Kumari , Kowluru Renu A.
Published: December 2022

Mitochondria experience genomic and functional instability in diabetes, and mitochondrial dysfunction has a critical role in the development of diabetic retinopathy. Diabetes also alters expressions of many long non-coding RNAs (LncRNAs), the RNAs with >200 nucleotides and no open reading frame. LncRNAs are mainly encoded by nuclear genome, but mtDNA also encodes three LncRNAs. Our goal was to investigate the effect of hyperglycemia on mtDNA-encoded LncRNA Cytochrome B (LncCytB) in mtDNA stability in diabetic retinopathy. Retinal endothelial cells, transfected with LncCytB- overexpressing plasmids or siRNA, incubated in 5mmols/L (NG) or 20mmols/L (HG) D-glucose for four days, were analyzed for LncCytB expression by strand-specific PCR, and its mitochondrial localization by RNA-FISH. Damage sensitive mtDNA regions were examined by micrococcal nuclease digestion-sequencing, and LncCytB occupancy at mtDNA by chromatin isolation by RNA purification. Protective nucleoids in mtDNA were analyzed by SYBR green-MitoTracker Red staining, and confirmed in isolated mitochondria by flow cytometry. Compared to NG, HG downregulated LncCytB by >50%, but had no significant effect on the other mtDNA-encoded LncRNAs. mtDNA packaging was impaired and MNase sensitivity was increased, and LncCytB occupancy at mtDNA was decreased. While LncCytB overexpression ameliorated mtDNA damage and decrease in nucleoids and copy numbers, LncCytB-siRNA exacerbated damage and further reduced nucleoids. Retinal microvessels from streptozotocin-induced diabetic mice and human donors with diabetic retinopathy presented similar decrease in LncCytB and mtDNA nucleoids. Thus, LncCytB has a major role in maintaining mitochondrial genomic stability, and its downregulation in hyperglycemic milieu contributes to increased vulnerability of mtDNA to damage.
Å gjøre «hørestyrke» til en mindre fortelling om barns språk
Authors: Lerbak Kari , Skoglund Tonje , Otterstad Ann Merete
Published: December 2022

I boka Lyttende pedagogikk trekker Ann Åberg og Hillevi Lenz Taguchi (2006) hørestyrke fram som en del av en lyttende pedagogikk. I boka refereres det til Filip som omtaler hørestyrke som å høre nøye etter. Vi er inspirert av Filip og hans ide om hørestyrke for å undersøke tettere hva barns språk kan romme. Vi prøver ut «å gjøre hørestyrke » og spør hva det kan være. Vi er interessert i hva, hvor og hvordan «å gjøre hørestyrke» kan åpne for å lytte til hele kroppen, rytmer, tramp og lette bevegelser. I prosessen med å utforske potensial av hva «å gjøre hørestyrke » kan handle om, har vårt empiriske materiale vært en mobilfilm av et barn som utforsker en kjøkkentrapp ute, samt utvalgte stillbilder, samlet inn via en mobiltelefon. Med spesiell interesse for hvordan kropper, vitalitet, bevegelser, lyd og rytme kommer fram gjennom mobilfilmen, bruker vi begrepene til Deleuze og Guattari; et mindre språk, maskineri og territorier (1994) som analyseverktøy. Begrepene brukes som mulige inspirasjoner til å undersøke det «å gjøre hørestyrke». Et av potensialene til «å gjøre hørestyrke» kan være «emergent lytting» (Davies, 2014) der også taushet og det mer-enn-menneskelige fenomenet gis verdi. Drøftingen kommer fram innunder overskriftene territorium, fellesskap som vitalitetskraft og det stille tause. 
ENGLISH ABSTRACT
Exercising ‘strong listening’ towards a minor story of children’s languageIn the book ‘Lyttende pedagogikk’/Pedagogy of listening by Ann Åberg and Hillevi Lenz Taguchi (2006) it is suggested ‘strong listening’ (hørestyrke) as a part of pedagogy of listening. The book describes the voice of the child Filip who says that ‘strong listening’ is about listening carefully. Inspired by Filip and his idea of ‘strong listening’, we try to investigate what children’s language can offer. By exercising ‘strong listening’ and ask what it could be, our interest is to question what, where and how ‘strong listening’ can open for listening to the whole body, rhythms and movements. In the process of exploring the potentials of ‘strong listening’, our empirical material has been a mobile film of a child exploring a step ladder outside, as well as selected still images collected via a mobile phone. With special interest of how bodies, vitalities, movements, sounds, and rhythms emerge through the mobile film, we use the concepts of Deleuze and Guattari; a minor language, machines, and territories (1994) as analytical tools. The concepts are used as possible inspirations to examine the ‘strong listening’. One of the potentials of ‘strong listening’ can be ‘emergent listening’ (Davies, 2014) where silence and the more-than-human also are given value. The discussions in the article are presented under the headings ‘Territorium/territories’, ‘Fellesskap som vitalitetskraft/collectivness as vitalities’ and ‘Det stille tause/the silent silence.
Förskollärares reflekterade praktik – en undersökning om pedagogisk handledning och pedagogisk dokumentation
Authors: Häikiö Tarja
Published: December 2022

Studien syftar till att belysa praxisbaserade perspektiv på yrkesverksamhet i förskolan på en övergripande nivå, och specifikt förskollärares reflekterande processer kring rollen som pedagogisk handledare och arbetet med pedagogisk dokumentation. Studien bygger på förskollärares analyser av reflekterad praktik i förskolan i skriftliga texter baserade på deras studentlogg under en universitetskurs i en akademisk fortbildning till pedagogiska handledare. I resultatet framkommer hur förskollärarna reflekterar kring potentiella möjligheter med handledarrollen, men också svårigheter med pedagogisk handledning och pedagogisk dokumentation som arbetsmetod utifrån sin personliga utveckling under fortbildningen. Resultatet visar hur förändrade förutsättningar riskerar att leda till försämrad kvalitet i förskolan och hur pedagogisk handledning kan vara ett sätt att sprida kunskap och stärka kollegial samverkan och kvalitet.
ENGLISH ABSTRACT
Preschool teachers’ reflected practice – a study on pedagogical supervision and pedagogical documentation
The study aims at shedding light on practice-based perspectives on professional activities in early childhood education on an overall level, and specifically preschool teachers’ reflective processes on the role as pedagogical supervisor and the work with pedagogical documentation. The study is based on preschool teachers’ analyzes of their reflected practice in preschool in written texts based on student logs during an academic professionalization course to become pedagogical supervisors. The results show how the preschool teachers reflect on potential opportunities with the role of supervisor, but also difficulties with pedagogical supervision and pedagogical documentation as a working method based on their personal development during the academic training. The results show how changed conditions risk leading to deteriorating quality in preschool and how pedagogical supervision can be a way to spread knowledge and strengthen collegial collaboration and quality.
Att Stötta Nyfikenhetsdrivet Lärande i Förskolan
Authors: Kaneko John , Frankenberg Sofia J.
Published: December 2022

Nyfikenhet ges en central plats i förskolan och betraktas som en nyckel till lärande, särskilt inom pedagogik som tar sin utgångspunkt i barns utforskande. Samtidigt saknas empiriskt grundad kunskap om hur nyfikenhetsdrivet lärande kommer till uttryck och kan stöttas i förskoledidaktisk praktik. Syftet med denna studie är att undersöka hur pedagoger stöttar det nyfikna lärandet inom ramen för Reggio Emilia inspirerad utforskandepedagogik. Detta undersöks med hjälp av ett ramverk för stöttning av nyfikenhetsdrivet lärande kombinerat med detaljerade multimodala interaktionsanalyser av videoinspelad interaktion från utforskande aktiviteter inom ramen för den förskoledidaktiska praktiken Socio- Emotionellt, Materiellt Lärande (SEMLA). Den teoretiska utgångspunkten är att nyfiket lärande kan förstås som en cykel där (1) informationsgap uppmärksammas av barnet, (2) barnet söker eller inväntar information och som (3) fullföljs när information som fyller informationsgapet erhållits. Resultaten visar att pedagoger lägger tonvikt på olika delar i nyfikenhetscykeln, att pedagoger är inbegripna med att validera information som erhållits och att det är av betydelse för pedagoger att vara medvetna om barns förkunskaper när ambitionen är att sätta igång och stötta deras nyfikenhet i riktning mot ett specifikt lärande.

Frontloading gross anatomy: impacts on medical student performance
Authors: Anderson Hana , Beck Kenneth A. , Tucker Richard P.
Published: December 2022

Objectives: The human gross anatomy course offered at the University of California, Davis, School of Medicine, is part of a partially integrated foundational block in the first year of the medical curriculum. The block organization was implemented in 2006 in part to foster the horizontal integration of four basic science courses. However, simultaneous instruction in multiple courses presented a challenging workload to students, especially considering the large amount of information covered in anatomy. In an attempt to improve student outcomes, the gross anatomy course was compressed and frontloaded to the first 13 weeks of the foundational block while instructions of other courses were shifted later to make room for the frontloaded gross anatomy course. To assess the effect of frontloading of anatomy on students’ performance, we retrospectively compared the anatomy examination scores between before and after frontloading of the anatomy content. Methods: Student performance in the gross anatomy course was compared between the pre-frontloading (2013–2015) and post-frontloading (2016–2018) cohorts. Average scores of each examination category (quizzes, midterms, practical and written finals, and overall grades) were calculated and compared between the two cohorts. Results: Scores on the written final and practical final examinations and the overall grade in gross anatomy improved significantly (p<0.05) in the post-frontloading cohort (n=323) compare to the pre-frontloading cohort (n=343). Conclusion: Moving gross anatomy forward and offering a compressed course may be an option for educators looking to improve student performance without increasing student contact hours, concomitantly allowing focused learning and mastery of anatomy content.
Modelling the effect of concrete cement composition on its strength and failure behavior
Authors: Saksala Timo , Kolari Kari , Kouhia Reijo
Published: December 2022

Typical concrete is a mixture of Portland cement, water, and aggregates. While aggregates have a substantial effect on the concrete strength and fracture behavior, the focus of the present study is on the hardened cement paste which can be further divided into the unreacted core, inner and outer products. In high strength concrete, water-to-cement ratio is low, and thus the distance between cement particles is small. Also, the amount of unreacted (high strength) core is higher, and the porosity is low. When water-to-cement ratio is higher, both the distance between cement particles and the porosity due to capillary pores increases. In the present study, we develop a numerical model based on the embedded discontinuity finite elements to predict the effect of the water-to-cement ratio on the compressive fracture behavior of concrete. Representative 2D plane strain simulations demonstrate that the present method captures the major features of concrete fracture and, particularly, qualitatively predicts the known effects of the water-to-cement ratio on concrete compressive strength.

Published: December 2022

Among all the sub-sectors of the livestock sector in Bangladesh, poultry stands as one of the most important ones. To evaluate the production performances and egg quality of four commercial layer strains in Bangladesh, a total of 128 laying pullets including NOVOgen brown, ISA brown, Hy-line brown, and Bovans brown were randomly allocated at 4 different treated groups (one individual strain treated as separate treatment) having 4 replications and 8 birds in each replication. The birds aged 20 weeks were considered for the experiment and continued until 35 weeks of age. A commercial layer diet purchased from Kazi Farms Group was fed to the experimental birds. Identical management was provided to the birds irrespective of their strains. Data on feed intake, egg production and body weight were recorded and thereafter egg mass and feed efficiency were calculated. Eggs were collected from the respective treatments and subjected to external and internal egg quality analysis. The results revealed that Hy-Line brown had significantly (p<0.001) lower feed intake compared to other strains. On the other hand, NOVOgen Brown had the significantly (p<0.05) higher shell thickness among others. Other laying performances such as hen-day egg production, average egg weight, egg mass and egg quality parameters such as shape index, Haugh unit, albumen index, and yolk color score did not affect significantly (p<0.05). Taken together, it may be concluded that there were almost no statistical differences in relation to laying performance and egg quality among the strains compared in this study and the strains are highly compatible to the local climatic condition.
