Effects of LHRH, progesterone, estradiol-17 ? and dexamethasone in vitro on pineal synaptic ribbons and serotonin N-acetyltransferase activity in die…

1991

Pineal glands of regularly cycling Sprague Dawley rats (180-220 g) killed on the diestrous morning (between 0900-1000 h) were incubated in appropriate media for six hours with LHRH (8.5 microM), progesterone (3.2 microM), estradiol-17 beta (370 nM) or dexamethasone (250 nM). Pineals incubated in hormone-free medium and unincubated glands served as controls. Six rats were used in each group. After incubation the glands were divided into two parts. One part was used to estimate serotonin N-acetyltransferase (NAT) activity. The other part was processed for electron microscopy to quantify synaptic ribbons (SR). The SR numbers were computed to 20,000 microns 2 area of pineal tissue. The number a…

Hormonal responsiveness in the Trier Social Stress Test and the dexamethasone‐corticotropin releasing hormone test in healthy individuals

2021

A number of different laboratory procedures investigate the hormonal response in a standardized pharmacological challenge test (dexamethasone-corticotropin releasing hormone; DEX-CRH) or in a psychosocial stress induction on the hypothalamic-pituitary-adrenocortical axis by the Trier Social Stress Test (TSST). However, the magnitude of the response related to the different stressors and the interaction of the responsiveness between the two tests is still unclear. Fifty-two participants underwent both the DEX-CRH test and the TSST on two separate days. The cortisol and the plasma adrenocorticotropic hormone (ACTH) release were assessed before and after the stress tests. For a specification o…

Effects of dexamethasone on human synovial fibroblast-like cells, from osteoarthritic joints, in culture.

1990

The effect of Dexamethasone (DEX) on cell division and macromolecular synthesis was investigated in a line (McCoy cells, A 9) of synovial fibroblast-like cells derived from human osteoarthritic joints. DEX markedly reduced the proliferation of McCoy cells in a time and dose-dependent manner. The maximal inhibition (45%) was found at 500 nM DEX 24 h after incubation and was accompanied by the appearance of giant macrophage-like cells. After DEX treatment cells showed increased content of DNA, proteins and RNA together with the reduction of [3H]-thymidine incorporation into the TCA-precipitable fraction.

El Examen en la Enseñanza de la Historia

2001

En este artículo se trata sobre la influencia del examen en la enseñanza de la Historia, tanto en lo que respecta a la configuración del conocimiento histórico escolar -que termina adoptando características apropiadas al hecho examinatorio- como a las prácticas pedagógicas y a la actuación de alumnos y profesores en la clase, que resultan asimismo determinadas por esta circunstancia. El análisis del papel del examen se vincula con la función crediticia del sistema escolar y con las circunstancias concretas en las que se produce su elaboración y corrección en el contexto escolar. This article deals with the influence of the exam in the teaching of History; in respect to the configuration of …

The Influence of Student Abilities and High School on Student Growth: A Case Study of Chinese National College Entrance Exam

2019

Enabled by available educational data and data mining techniques, educational data analysis has become a hot topic. Current researches mainly focus on the prediction of problems and performance rather than revealing the underlying causal relationships. Based on a unique exam data, we extracted the abilities of examinee from HSEE (High School Entrance Exam) based on the knowledge of educational experts, then we measured student growth from middle school to high school in total score and subject scores. We studied the impact of high school ranking and student abilities of HSEE on student growth by multiple linear regression model, in which high school ranking is divided into 5 levels, Level 1…

Oral proficiency in second and third foreign languages in the Danish education system

2019

In this paper, we analyze how oral proficiency is understood in the Danish education system in the three biggest second/third foreign languages taught in the country: French, Spanish and German. We adopt a comparative perspective and analyze how orality is addressed in these language subjects at primary school, secondary school and university levels. We compare the three languages to find similarities and differences, focusing on learning objectives, pedagogical approaches and examination forms, presented in the official curricula for each of the three educational levels. We relate the Danish stance on oral proficiency to current international research in the field and to European tendencie…

Józefa Piłsudskiego "droga do niepodległości" w świadomości młodzieży. (Na przykładzie zadań z historii w arkuszach egzaminów zewnętrznych)

2017

Artykuł ukazuje obraz Józefa Piłsudskiego w zadaniach z historii, które przygotowywane zostały na potrzeby ogólnopolskich egzaminów zewnętrznych przez Centralną Komisję Egzaminacyjną. Przeanalizowano zadania z arkuszy gimnazjalnych oraz maturalnych. Analiza wykazała satysfakcjonującą obecność Józefa Piłsudskiego w poleceniach odnoszących się do wydarzeń z I wojny światowej, gdy jego droga do wolnej Polski była już na ostatniej prostej.

Using eye-movement modelling examples to improve critical reading of multiple webpages on a conflicting topic

2022

This project investigates the effects of an EMME intervention on undergraduates' sourcing when reading conflicting multiple texts on the Internet. Dependent variables: eye-movements on SERP, webs header, texts authors, and texts; use of source information in summaries; ideas from texts in summaries.

Finite element approximation for a div-rot system with mixed boundary conditions in non-smooth plane domains

1984

The authors examine a finite element method for the numerical approximation of the solution to a div-rot system with mixed boundary conditions in bounded plane domains with piecewise smooth boundary. The solvability of the system both in an infinite and finite dimensional formulation is proved. Piecewise linear element fields with pointwise boundary conditions are used and their approximation properties are studied. Numerical examples indicating the accuracy of the method are given. peerReviewed
