Pochwała szlachcianki w świeckich mowach pogrzebowych Jakuba Sobieskiego (I połowa XVII wieku)
Authors: Ciszewska Małgorzata
Published: January 2021

Celem artykułu jest przedstawienie specyfiki oracji pogrzebowych Jakuba Sobieskiego, a tym samym uzupełnienie luki w badaniach nad świeckimi oracjami pogrzebowymi, stanowiącymi ogromną część staropolskiego oratorstwa, które dopiero od kilku lat są wyraźnie wydzielane w badaniach literaturoznawczych i historycznych spośród ogółu pogrzebowej „produkcji” oratorskiej i literackiej jako osobne i specyficzne typy tekstów. Jakub Sobieski, jeden z najznakomitszych mówców I połowy XVII stulecia, wygłosił dwadzieścia siedem oracji pogrzebowych, z których pięć poświęconych było kobietom. Zgodnie z regułami retorycznymi zawarł w nich pochwały zmarłych szlachcianek, które to enkomiony złożyły się na określony wzór osobowy: żony, matki i wdowy. Elementy wzoru kobiety analizowane były do tej pory niemal wyłącznie na przykładach kazań pogrzebowych – niniejsze studium jest pierwszym, które ujmuje zagadnienie z perspektywy mów szlacheckich. Kluczowe jest tu rozpoznanie nie wzoru osobowego, gdyż ten – jak się okazuje – jest w zasadzie niezmienny niezależnie od gatunku oratorskiego, ile sposobów amplifikacji toposów kobiecej pochwały. Na podstawie przeprowadzonych analiz stwierdzono, że Sobieski w większości przypadków (do wyjątków należą mowy na pogrzebie Reginy Żółkiewskiej i Anny Ostrogskiej) preferuje nazwanie i wyliczenie cnót kobiecych pozbawione egzemplifikacji faktograficznej. Stanowi to jaskrawy kontrast zarówno w stosunku do jego laudacji męskich, obfitujących w szczegółowe opisy zasług i dokonań zmarłych, jak i do praktyki kaznodziejskiej epoki.
La paratopie créatrice dans "Nulle Autre Voix" de Maïssa Bey
Authors: Beneddra Mohammed Rachid
Published: January 2021

Celem artykułu jest analiza powieści Maïssy Bey Nulle autre voix. Feministyczna autorka zajmuje się nowym, trudnym problemem: kwestią obecności Algierki w więzieniu, miejscu przeznaczonym tylko dla mężczyzn. Podejmuje również problem tabu w kulturze algierskiej, jakim jest przestępczość kobiet taktowana jako rodzaj desocjalizacji – rodzina wyklucza przestępczynię za okrycie niesławą najbliższych. Powieść Maissy Bey pokazuje, iż kobieta jest traktowana znacznie bardziej rygorystycznie niż mężczyzna, gdyż utożsamia honor rodziny. W artykule poddano analizie te kwestie za pomocą metody enucjatywnej – pokazano, jak powieści Nulle autre voix tworzą one paratopiczny dyskurs.
Minor Victim Representation in Cases of Crimes Committed by Family Members in Polish Law
Authors: Łakomy Kamil
Published: January 2021

The study presents the current legal regulations and problems with the implementation of procedural rights of a minor victim in the case of crimes committed by members of his family in the Polish legal system. The presented issue concerns the necessity to apply provisions contained in various acts, both public and private law. The author discusses the most important judgements of Polish jurisprudence in the indicated scope, emphasizing, however, that many aspects of the discussed issues, of a procedural nature, have still not been regulated. The conclusions include de lege ferenda postulates concerning, i.a., the transfer to the criminal court of the competence to appoint a guardian ad litem for disadvantaged minors.

Spectral Dynamic Analysis of Torsional Vibrations of Thin-Walled Open Section Beams Restrained Against Warping at One End and Transversely Restrained at the Other End
Authors: Kameswara Rao 1 Chellapilla , Bhaskara Rao 2 Lokavarapu
Published: January 2021

The present paper deals with spectral dynamic analysis of free torsional vibration of doubly symmetric thin-walled beams of open section. Spectral frequency equation is derived in this paper for the case of rotationally restrained doubly-symmetric thin-walled beam with one end rotationally restrained and transversely restrained at the other end. The resulting transcendental frequency equation with appropriate boundary conditions is derived and is solved for varying values of warping parameter and the rotational and transverse restraint parameter. The influence of rotational restraint parameter, transverse restraint parameter and warping parameter on the free torsional vibration frequencies is investigated in detail. A MATLAB computer program is developed to solve the spectral frequency equation derived in this paper. Numerical results for natural frequencies for various values of rotational and transverse restraint parameters for various values of warping parameter are obtained and presented in both tabular as well as graphical form showing the influence of these parameters on the first fundamental torsional frequency parameter.
Impaired circadian rhythm of blood pressure predicting adverse events in preeclampsia
Authors: Vijayvargia Nitisha , Samariya Meenakshi
Published: January 2021

Background: Physiologically Blood pressure is higher during the day time (between 09 AM to 6 PM) and lower at night (10 pm to 3:00 am). During night both systolic and diastolic blood pressure readings drop by about 10-20%. In preeclampsia, the nocturnal decrease of BP is blunted and there is less variation among BP circadian values. Objective of the study is to know whether ratio of morning and nocturnal mean diastolic blood pressures calculated by timed i.e., 6 hourly blood pressure monitoring could be used to predict the prognosis of preeclampsia as in terms of Maternal and fetal prognosis.Methods: A prospective study is done using 6 hourly blood pressure measurements of antenatal patients in third trimester admitted for gestational hypertension or preeclampsia and their observation till delivery was done. Results: It is observed that non dipping and increased nocturnal diastolic blood pressures pattern causing reverse dipping pattern are significantly associated with increased severity of disease (p=000). Both maternal (p=0.04) and fetal adverse event (p=0.004) increased significantly with blunting of decrease in nocturnal blood pressures.Conclusions: We thus can conclude that blunting/reversal of circadian rhythm of blood pressure indicates progress of disease to its more severe form. It thus could be of great help in deciding for monitoring, timing of antihypertensives and prophylactic medications and deciding for termination of gestation.

Published: January 2021

Background: Aim were to study the clinical presentation and predisposing factors in children with deep neck space infections and to study the effective mode of management of pediatric deep neck space infections and its complications.  

Methods: This prospective study was done in a tertiary care hospital on 163 pediatric patients with deep neck space infections who were thoroughly examined to know the source of the infection. Ultrasonography of neck and Radiological investigations were done to determine the location and extent of the abscesses. All patients were started on empirical antibiotic therapy of amoxicillin and clavulanic acid and metronidazole. Patients with small abscess were blindly aspirated with wide bore needle, while incision and drainage were done for large abscess. The pus samples from both were sent for culture and sensitivity. Patients presenting with complications, underwent incision and drainage. Patients, who failed empirical antibiotic therapy and needle aspiration, then underwent incision and drainage.   

Results: The most common symptom and sign was neck swelling (85%). The next most common symptom was neck pain (70%). Most of the patients had unknown source of infection and others had history of recurrent sore throat, dental infections, acute cervical lymphadenopathy, parotitis and furuncle over neck.  

Conclusions: Deep neck space infections (DNI’s) in pediatric population constitutes of medical emergency as it could lead to life threatening complications in a short time. Though with changing times of new diagnostic and therapeutic tools have drastically reduced the incidence of complications.
Sozialkontrolle und Bekämpfung von politischem Extremismus: Was halten Schweizerinnen und Schweizer davon?
Authors: Staubli Silvia
Published: January 2021

In den letzten Jahren wurde viel in die Erforschung von Radikalisierung und in Massnahmen zur Bekämpfung von Extremismus und Terrorismus investiert. Dies geht einher mit einer zunehmenden Sozialkontrolle, welche sich unter anderem in Gesetzesverschärfungen äussert. Was aber die Schweizer Bevölkerung von solchen Massnahmen hält, wurde bis anhin nur rudimentär erforscht. Relativ unklar bleibt, wie Einstellungen zur Bekämpfung von Extremismus erklärt werden können. Dieser Artikel schliesst diese Lücke indem er der Frage nachgeht, ob die Zustimmung zu einer vermehrten Sozialkontrolle die Befürwortung einer stärkeren Bekämpfung von Rechts- und Linksextremismus in der Schweiz beeinflusst. Er knüpft hierbei an die Forschung zu Sozialkontrolle und Extremismus an und stützt sich auf Daten der Studie Sicherheit 2016.
Detection of Epistasis for Biometrical Traits in Urdbean [Vigna mungo (L.) Hepper] under Mid-hill Conditions of Northwestern Himalayas
Authors: Patial Ranjana , Mittal R.K. , Sood V.K. , Kumar Nimit
Published: January 2021

Background: Pulses are rich in their nutritional values, but having lower yield as compared to cereals. For increasing yield parameters, various crop improvement programmes were used, which mainly depends on the genetic architecture of the crop and the type of gene action helps in deciding the breeding strategies. Keeping under consideration, the present study therefore, is important. Methods: Eighty one triple test cross progenies developed by crossing 27 lines with three testers viz., HPBU-111, Him Mash-1 and their F1s cross between (HPBU-111 x Him Mash-1). F1 seeds were produced by cross between HPBU-111 x Him Mash-1 during Kharif 2015. By crossing these three testers with 27 lines (females), 81 hybrids were developed during Kharif 2016. The eighty one F1 hybrids along with 27 lines and 3 testers were sown during Kharif 2017 in a randomized block design with three replications. Result: Epistasis was found to be an integral part of genetic variations for the traits viz., days to 50% flowering, days to 75% maturity, plant height (cm), number of branches per plant, pod length (cm), number of pods per plant, number of seeds per pod, seed yield per plant (g), biological yield per plant (g), 100 seed weight, harvest index (%) and protein content (%). i type epistatic interactions (additive x additive) had significant effects for all the traits except, plant height (cm), pod length (cm), number of seeds per pod and protein content (%). In addition to i (additive x additive), j+l (additive x dominance + dominance x dominance) type epistatic interactions was observed for all of the traits. Both additive and non-additive gene actions are important for most of the traits studied hence, simple selection procedures in the immediate progenies will not be so effective for achieving improvement in these traits.

Published: January 2021

Forming one of the most important branches of our culture and traditional arts, embroidery was born by sewing in a decorative way and it is worth mentioning that it is as early as humanity. Embroidered clothing on the sculptures excavated and the narration that the daughter of Noah in Hebrew history wears an embroidered belt shows that this branch of art goes back to earlier times. Hand embroidery, which is the products of intelligence, skill and subtle wit, has reached the current time by preserving its value. Out of a great many embroidery techniques reaching large public masses, a technique called ‘German Embroidery’ was encountered in the researches carried out in the city of Kahramanmaras and its towns in the years 2013–2014. According to the information obtained from the source people in the research carried out in the city of Kahramanmaras, German Embroidery dating back to earlier times is not produced today; however, we are likely to find pillows, clothes and dresses embroidered with German Embroidery in houses. In the current paper, embroidery samples were determined in order to unveil this technique that was embroidered on any kind of cloth with a plain surface and it was aimed to make the embroidery alive and to promote it by analysing the way of embroidering.

Advances in root architectural modeling
Authors:   Forschungszentrum Jülich, Germany, Postma Johannes A. , Black Christopher K. ,   The Pennsylvania State University, USA
Published: January 2021

Root architectural (RSA) models have become important tools in root research and plant phenotyping for studying root traits, processes, and interactions with the environment. The models have been used to simulate how various root traits and processes influence water and nutrient uptake. At a more technical level, they have been used to develop phenotyping technology, particularly for testing algorithms for segmenting roots. To compute these quantitative estimates regarding plant nutrition and root functioning, much development occurred in the last decade increasing the complexity of the models. This chapter describes first the application of the models to questions in plant biology, breeding, and agronomy, and second the development of the models. It concludes with a small outlook suggesting that models need benchmarking and validation and that new developments are likely to include better descriptions of root plasticity responses and focus on biological interactions among (soil) organisms, including mycorrhizal fungi.

At a global scale, phosphorus (P) deficiency comprises a large area of cropland, while P has also been used in excess of crop requirements in many other regions. Improved crop P-acquisition efficiency would allow lower target critical soil P values and provide savings in P-fertiliser use. At the same time, it would reduce P lost through erosion, leaching and/or soil sorption. This chapter summarises the progress in research on root traits associated with P acquisition, including root morphology, architecture, biochemistry, colonisation by arbuscular mycorrhizal fungi, and fine root endophytes, and the trade-offs among all these traits. Farming-management practices to improve P acquisition under current intensive agricultural systems are also discussed. The chapter summarises breeding progress in improving P-acquisition efficiency. In the face of soil P deficiency or legacy P globally, the chapter suggests future directions to improve P acquisition in five key areas.

Arbuscular mycorrhizal fungi (AMF) form endosymbiosis with over 70 % of land plants, including most crops including cereals. These symbioses facilitate resource exchange between partners and can significantly increase plant nutrient uptake and growth, among other benefits. AMF ubiquity in agricultural soils, in addition to the many roles they are known to play in soil health, demands we consider them when discussing crop function. We discuss how AMF are capable of increasing crop acquisition of macro- and micronutrients. We examine further impacts that AMF have on root system architecture, and how this relates to nutrient acquisition. We highlight reasons why potential benefits of the symbiosis are often not realised and how this influences current perspectives on the utility of AMF. We also discuss aspects of modern agronomy practice which are deleterious to mycorrhizal functioning. Strategies are suggested by which mycorrhizas might be exploited in future highlighting future research priorities.

Authors: AGESTY ELSYA
Published: January 2021

This study was aimed at describing the relationship between thinking style and reading comprehension of students at one Madrasah in Palembang, South Sumatera. The method used in this study was correlational research. The population of the research was eleventh grade students. There were 452 students from eleventh grade classes as the population in this study. The sample was taken by using purposive sampling which consisted of 147 students. Furthermore, there were two variables in this research. The first one was students’ thinking style (variable X) and the second one was the students’ reading comprehension skill (variable Y). The students’ thinking style score was taken from the questionnaire, while the students’ reading comprehension score was taken from a test. Based on the data analysis, it was found that the r-obtained (-.008) was lower than r-table (0.162). Then the level of probability (p) significance (sig.2-tailed) was .928. It indicated that p (.928) was higher than 0.05. It implied that null hypothesis (H0) was accepted and the alternative hypothesis (Ha) was rejected. From the finding, it could be concluded that there was no significant relationship between the students’ thinking style and their reading comprehension skill. It showed that the students’ thinking style was not a dominant factor that affected the reading comprehension.

Published: January 2021

Background Obesity is considered as one of the risk factors for heart disease, cancer, diabetes, greater rates of mortality as young adults. Objectives Body composition affects physical fitness, but no relation to sex and the degree of obesity was investigated so far in Polish adolescents. Material and methods The studies involved 118 adolescents (12 to 18 years old) who were overweight or obese. The assessment of the body composition was performed by measuring the bioimpedance. The concentration of alpha1-acid glycoprotein and alpha1-antichymotrypsin was measured by immunoelectrophoresis. The glycosylation profiles of AGP and ACT were investigated by crossed-affinity immunoelectrophoresis with Concanavalin A. Physical fitness was measured using the Eurofit test. Results In the study group of girls the body fat content determined on the basis of bioimpedance is not significantly different for overweight and obesity, whereas in the group of boys it is significantly higher in obese individuals. Fitness tests showed a heterogeneous impact of obesity on fitness: some results of the tests were good (FLB, PLT, SAR, HGR) in other tests (SBJ, SUP, BAH, ESR, SHR) the results were considerably inferior. The study of acute phase proteins showed elevated levels of AGP, higher in boys, lower reactivity with ConA in overweight boys and girls, and higher reactivity with ConA in obese boys and girls. Conclusion As the BMI percentile, waist circumference and waist-to-height ratio increase, the results of fitness tests, measured using the EUROFIT test, deteriorate. The consequences of excessive body fat are greater for boys, both in terms of abnormal laboratory markers and physical fitness.
Percepções sobre a Geodiversidade em trilhas de montanha
Authors: Pessoa Fernando Amaro , Brito Adriel Filipe Soares , Pacheco Fábio Feler , Peixoto Maria Naíse de Oliveira , Mansur Kátia Leite
Published: January 2021

O conceito de Geodiversidade – que enfatiza uma visão integrada dos elementos e processos abióticos e bióticos, com características, funções e serviços ecossistêmicos associados – ainda é pouco conhecido e, consequentemente, pouco divulgado, apesar de ser apropriado na prática em inúmeras atividades, como por exemplo o montanhismo em unidades de conservação. O presente artigo tem como objetivo promover uma melhor compreensão da percepção dos visitantes sobre a Geodiversidade em trilhas, a partir do estudo de caso da Travessia Petrópolis-Teresópolis. Para isso, foi elaborado um questionário que, após divulgação em diversos meios, alcançou um diversificado público. Os resultados indicam a necessidade de se avançar no tema para se obter a elaboração de roteiros geoturísticos e geodidáticos com uma inserção mais adequada no território onde são propostos, além de reforçarem a necessidade de uma abordagem multi-escalar e geossistêmica para esses estudos, o que pode favorecer um entendimento mais amplo acerca da Geodiversidade.
Le lycée permet-il aux jeunes de comprendre l’élevage ? État des lieux et propositions
Authors: CHOUTEAU Alizée , DISENHAUS Catherine , BRUNSCHWIG Gilles
Published: January 2021

Aujourd’hui les liens entre agriculture et société s’étiolent, avec un niveau de connaissances du public qui diminue du fait de son éloignement familial progressif vis-à-vis du monde agricole. Dans cet article, nous avons étudié le public des jeunes adultes, pour faire un état des lieux de la place de l’élevage dans l’enseignement secondaire. L’objectif était de mieux connaître les thèmes abordés, les informations utilisées et leurs sources, afin de répondre à des observations régulières de professionnels des différentes filières d’élevage qui estiment que ce qui est enseigné aux élèves est en décalage avec la réalité. L’étude montre que les lycéens français ont une perception de l’élevage similaire à celle du reste de la population, avec cependant une préoccupation importante pour la préservation du bien-être animal et de l’environnement. Ils ont également plus tendance à se tourner vers des régimes végétariens ou végétaliens. Leur niveau de connaissances est faible, comme pour le reste de la population, et ils indiquent que l’enseignement est leur troisième source d’information sur l’élevage. Les programmes du lycée en vigueur jusqu’à la rentrée 2019 prévoyaient que le sujet agricole soit abordé en Sciences de la Vie et de la Terre (SVT) et en Géographie dans les filières générales, mais force est de constater avec la réforme que ce sujet devient particulièrement anecdotique (le chapitre « nourrir l’humanité » a notamment disparu des programmes de géographie en 2020). La difficulté d’enseigner l’élevage a été confirmée par les enseignants enquêtés, qui ont en plus précisé que ce sujet était parfois compliqué pour eux à traiter, et donc souvent mis de côté. L’une des difficultés mentionnées est de trouver des ressources pédagogiques qu’ils jugent adaptées : les manuels sont considérés comme une solution facile, mais de notre point de vue, leur contenu en lien avec l’agriculture est souvent discutable, notamment en l’absence de sources pour les informations présentées. Ce point nous est apparu comme nécessaire à corriger, indépendamment des points de vue que l’on peut avoir sur l’agriculture et en particulier sur l’élevage. Nous avons donc proposé des ressources adaptées à l’enseignement au lycée et mentionnant les sources utilisées, car il s’agit d’un enjeu important d’objectivité et de construction de l’esprit critique des citoyens et des décideurs de demain.

Published: January 2021

Abstract: Magnetoimpedance (MI) effect was observed on multilayer samples [Ni80Fe20(800)nm)/Cu(x)nm]4 Cu-Printed Circuit Board substrates. The multilayer system was grown through an electrodeposition process by modifying thickness of the Cu layer. The MI effect was analyzed by means of an impedance test under an external magnetic field at low frequency 100 kHz. The  results found that MI ratio increased ± 1.02 fold with the reduction Cu layer (800 nm until 0 nm) from 2.39% to 3.44%. This condition is believed by differences resistance of magnetic layer to conductive layer in the multilayers system. The measured sample resistance value is inversely proportional to the function of “x” as the thickness of the conductive layer. This means that the reduction conductive layer can be improve magnetic properties for a multilayer [Nife/Cu]N system. The analysis calculation of the sensitivity value also shows the potential  increase sample sensitivity to 0.9746% / mT.

Abstrak: Magnetoimpedansi (MI) telah diamati untuk sampel multilapisan [Ni80Fe20(800)nm)/Cu(x)nm]4 substrat Cu-Printed Circuit Board. Sistem multilapisan ditumbuhkan melalui proses elektrodeposisi dengan memodifikasi ketebalan lapisan Cu. Efek MI dianalisis melalui pengujian impedansi dibawah medan magnet luar pada frekuensi 100 kHz. Hasil uji ditemukan rasio MI meningkat ±1.02 kali lipat dengan berkurangnya lapisan Cu (800 nm sampai 0 nm) dari 2,39 % menjadi 3,44 %. Kondisi ini diyakini oleh adanya perbedaan resistensi lapisan magnetik dengan lapisan konduktif pada sistem multilapisan. Nilai resistensi sampel yang terukur berbanding terbalik terhadap fungsi x sebagai ketebalan lapisan konduktif. Artinya berkurangnya lapisan konduktif dapat meningkatkan sifat magnetik sampel untuk sistem multilapisan [Nife/Cu]N. Analisa perhitungan nilai sensitifitas juga menunjukan potensi kenaikan sensitifitas sampel tertinggi sampai 0,9746 %/mT.

WITHDRAWN: Rejuvenation by enthalpy relaxation in metallic glasses
Authors: Meng Yonghua , Zhang Shi , Yao Jiahao , Lan Si , Li Yi
Published: January 2021

Usually structural relaxation would lead to embrittlement in metallic glasses (MGs). Here, we show that rejuvenation of relaxed MGs is achieved simply by a thermal exposure at a temperature higher than the annealing temperature (but below glass transition temperature). The effect is driven by enthalpy relaxation (an endothermic reaction upon heating relaxed MGs). This rejuvenation lifts the energy state of the relaxed glass towards that of the as-cast glass. Importantly, we demonstrate that the plasticity and fracture toughness of the rejuvenated samples exceed those of the as-cast state. An analysis of the structural changes shows that the rearrangement of cluster connectivity at the medium-range length scale is responsible for the rejuvenation. Our finding is significant for the tailoring of the mechanical properties of metallic glasses.

Background: Endotracheal suctioning is one of the most frequently operated invasive procedures by intensive care nurses. Nurses should have adequate knowledge and skills to perform endotracheal suctioning based on the best evidence. Litter is known about intensive care nurses' knowledge and practice of evidence-based endotracheal suctioning in Chinese hospitals. The purpose of this study is to investigate intensive care nurses' knowledge and practice of the evidence-based recommendations regarding endotracheal suctioning. Specifically, the study aims to examine 1) intensive care nurses' awareness of and adherence to the endotracheal suctioning guideline; and 2) their influencing factors.Methods: The cross-sectional online questionnaire survey was distributed to 310 intensive care nurses working in intensive care units of five tertiary hospitals in Changsha, China. Results: 281 nurses completed and returned the survey (response rate= 90.6%). Participants' awareness of and adherence to the evidence-based guideline was at a poor to moderate level. There was a significant difference regarding the awareness of the guideline between experienced and inexperienced nurses. Nurses who worked 6-15 years in intensive care units had a higher awareness of evidence-based endotracheal suctioning practices than nurses who worked within five years and over 16 years. Nurses with endotracheal suctioning training demonstrated significantly higher awareness of endotracheal suctioning recommendations and higher adherence levels than those untrained nurses.Conclusion: There are considerable evidence-practice gaps in ETS among Chinese intensive care practice. further research should emphasis on revealing barriers and facilitators of implementing the evidence-based endotracheal suctioning practices, developing context-suitable interventions for the guideline implementation. We suggest a systematic training of the ETS guidelines along with innovative implementation strategies from implementation science to promote the ETS practice changes.

Arthropod vectors carry vector-borne pathogens that cause infectious disease in vertebrate hosts, and arthropod-associated non-pathogenic microorganisms. Both types of micro-organisms can influence the fitness of their arthropod vectors, and hence the epidemiology of vector-borne diseases. The bacterium Borrelia afzelii, which causes Lyme disease in Europe, is transmitted among vertebrate reservoir hosts by Ixodes ricinus ticks, which also harbour a large diversity of non-pathogenic bacteria. The purpose of this study was to test experimentally whether B. afzelii and tick-associated non-pathogenic bacteria influence the fitness of I. ricinus. Eggs obtained from field-collected adult female ticks were washed with bleach, which reduced the abundance of non-pathogenic bacteria in the hatched I. ricinus larvae by 28-fold compared to larvae that hatched from eggs washed with water. The dysbiosed and control larvae were subsequently fed on B. afzelii-infected or uninfected control mice, and the engorged larvae were allowed to moult into nymphs under laboratory conditions. I. ricinus larvae that fed on B. afzelii-infected mice had a significantly faster larva-to-nymph moulting time compared to larvae that fed on uninfected control mice. In contrast, we found no evidence that B. afzelii infection or larval dysbiosis influenced the four other life history traits of the immature I. ricinus ticks, which included engorged larval weight, unfed nymphal weight, larva-to-nymph moulting success, and immature tick survival. A power analysis found that our sampling effort had sufficient power (>80%) to detect small effects (difference of 5% – 10%) of either B. afzelii infection or larval dysbiosis. Under the laboratory conditions of our study, B. afzelii appears to be a mostly passive passenger in I. Ricinus ticks.

Plastic pollution is of increasing concern to marine ecosystems worldwide. Specifically, microplastics (<5mm) may interact with a variety of biota with potential to cause harm to organism health. Studies concerning microplastics are increasing, yet their occurrence within live marine mammals remains largely unexplored. Here, faecal samples collected from a haul-out site in the North Sea, were used to investigate microplastic pollution within grey seals (Halichoerus grypus). 71 microplastic particles, consisting of both fibres and fragments in a variety of colours and sizes, were identified across 66 scat subsamples analysed. This indicates that marine mammals are ingesting microplastics and that faecal material can be used to indirectly and humanely record microplastic uptake data in pinnipeds. Since the current paper is the first to document microplastic exposure amongst wild, living and free-ranging grey seals in the North Sea, further research is needed to begin to understand the biological significance of these findings.

Background: With the development of genomics, ferroptosis has been determined to be highly important in cancer. The purpose of this study was to identify ferroptosis-related genes (FRGs) associated with the prognosis of pancreatic cancer and to construct a prognostic model based on FRGs. Methods: Based on pancreatic cancer data obtained from The Cancer Genome Atlas (TCGA) database, we employed univariate Cox analysis, least absolute shrinkage and selection operator (LASSO) analysis and multivariate Cox analysis to establish the prognostic model from 232 FRGs. A nomogram was constructed by combining the prognostic model and clinicopathological features. Gene Expression Omnibus (GEO) datasets and tissue samples obtained from our center were utilized to validate the prognostic model. Relationship between risk score and immune cell infiltration was explored by CIBERSORT and TIMER.Results: The prognostic model was established based on four FRGs (ENPP2, ATG4D, SLC2A1 and MAP3K5) and can be an independent risk factor in pancreatic cancer (HR 1.648, 95% CI 1.335-2.035, p < 0.001). Based on the median risk score, patients were divided into a high-risk group and a low-risk group. The KM curve indicated that the overall survival (OS) of the low-risk group was significantly better than that of the high-risk group. The nomogram showed that the prognostic model was the most important element. Gene set enrichment analysis (GSEA) identified three key pathways, namely, TGFβ signaling, HIF signaling pathway and adherens junction. GSE57495, GSE62452 and 88 pancreatic cancer tissues from our center were utilized to validate the prognostic model. The prognostic model can also affect the immune cell infiltration, such as macrophages M0, M1, CD4+T cell and CD8+T cell. Conclusion: A ferroptosis-related prognostic model can be employed to predict the prognosis of pancreatic cancer. Ferroptosis can be an important marker and immunotherapy can be a potential therapeutic target for pancreatic cancer.

Background: Liver hepatocellular carcinoma (LIHC) is one of the most common malignant cancers worldwide, the overall prognosis of LIHC remains unsatisfactory. Valuable prognostic biomarkers are still urgently needed for LIHC. This study aimed to explore hub genes associated with the prognosis of LIHC and tumor microenvironmental immune infiltration, providing potential prognostic biomarker and therapeutic target for LIHC. Methods: RNA-seq counts data for LIHC samples were obtained from TCGA database. RNA-seq counts data for normal liver samples were obtained from GTEx database. Weighted gene co-expression network analysis (WGCNA) was used to cluster differentially expressed genes with similar expression profiles to form modules and significant modules and key genes were screened. Next, these genes was verified by cox analyses and overall survival analysis. Further, CIBERSORT was used to explore the relationship between these genes and tumor infiltrating immune cells. Results: A total number of 2661 significant DEGs were included for consensus WGCNA analysis, which identified 6 modules. Blue module (r=0.85, p<0.0001) showed high relationship with LIHC, which included 400 genes. After the overall survival analyses of hub genes, CDC20, CDCA5, CDCA8, KIF2C and KIFC1 were identified as five potential marker genes, which would result in an unfavorable prognosis in LIHC. Further CIBERSORT analysis showed these novel biomarkers expression levels in LIHC were positively correlated with activated memory CD4+ T cells, follicular helper T cells, regulatory T cells and macrophages M0. While, resting memory CD4+ T cells, monocytes, macrophages M2, resting mast cells showed a negative correlation with the 5 novel biomarkers expression levels. Conclusions: The study screened 5 genes with marked prognostic capability for LIHC and found these genes were correlated with the infiltration of immune cells in LIHC tumor microenvironment. The findings might provide a more detailed molecular mechanism underlying LIHC occurrence and progression, holding promise for acting as potential biomarkers and therapeutic targets.
