Expression von Tenascin, Laminin und Fibronectin nach traumatischer vorderer Kreuzbandruptur
2008
In the present study, the pattern of some extracellular matrix glycoproteins was determined in traumatic anterior cruciate ligament ruptures (n = 17) and in normal ligaments (n = 11). 6 microns cryo-sections were incubated with monoclonal antibodies recognizing tenascin, laminin, and fibronectin, and FITC-labeled secondary antibodies. Immunohistochemistry revealed that tenascin, fibronectin and laminin are sparsely distributed in normal anterior cruciate ligaments, but strongly expressed in ruptured ligaments with a time-restricted pattern. The de novo-expression of tenascin appeared before laminin but later than fibronectin. The data suggest that fibronectin and tenascin are important, par…
The forgotten mathematical legacy of Peano
2019
International audience; The formulations that Peano gave to many mathematical notions at the end of the 19th century were so perfect and modern that they have become standard today. A formal language of logic that he created, enabled him to perceive mathematics with great precision and depth. He described mathematics axiomatically basing the reasoning exclusively on logical and set-theoretical primitive terms and properties, which was revolutionary at that time. Yet, numerous Peano’s contributions remain either unremembered or underestimated.
Occurrence and recovery potential of rare earth elements in Finnish peat and biomass combustion fly ash
2019
Rare earth elements (REEs) are highly important in the modern society as a result of their wide use in various fields of industry. Their high supply risk and increase in demand has led to classification as critical materials, and consequently, new resources for REEs are being prospected widely. Coal fly ash has been suggested as a possible secondary resource for REEs, but very little information is available regarding REE occurrence in biomass or peat derived fly ash. In this paper, fly ash samples from commercial power plants using peat and biomass as fuel were studied for REEs. The average concentration of REEs was 530 ppm, with up to 920 ppm in one fly ash. Five out of seven fly ashes we…
Skolēnu rakstīti dzejoļi angļu valodas darbības vārdu gramatisko laiku apguves veicināšanai 7. klasē
2016
Angļu valoda ir kļuvusi par sazināšanās valodu daudzās valstīs. Tomēr, lai nodibinātu veiksmīgu komunikāciju, darbības vārdu gramatisko laiku pareizam lietojumam ir jābūt apgūtam. Lai gan skolēni apgūst darbības vārdu gramatisko laiku likumus, skolēni bieži vien tos nesaprot. Diplomdarba mērķis bija izpētīt kā dažādi skolēnu rakstīti dzejoļi var veicināt angļu valodas darbības vārdu gramatisko laiku apguvi 7. klasē. Izvēlētā pētījuma metode bija atsevišķa gadījuma pētījums, kas ietvēra divas anketas skolēniem un trīs dzejoļu rakstīšanas uzdevumus. Tika noskaidrots, ka, mācot angļu valodas darbības vārdu gramatiskos laikus induktīvi, skolēni tos saprot labāk, ja ir aktīvi līdzdarbojušies. Pē…
Data of safety in a single-center alemtuzumab treated population
2020
Alemtuzumab is approved for highly active MS and, in Europe, can be employed after other disease-modifying treatments (DMTs) as an escalation approach or first therapeutic option. The occurrence of secondary autoimmune adverse events and infections differs depending on the employed approach.In the manuscript entitled “Alemtuzumab treatment of multiple sclerosis in real-world clinical practice: report from a single Italian center” by di Ioia M. and collaborators, efficacy and safety data of alemtuzumab were evaluated in a real-world MS population. The aim of the article is to describe in detail the unexpected serious adverse events which occurred in this cohort during and after the administr…
Der Stellenwert der Sepsis nach Laparotomie im Kindesalter
1984
Laparotomy was performed on 579 children at the University Clinic of Paediatric Surgery in Mainz from 1.1.1975 to 31.12.1982. The children were up to 15 years of age; appendicitis or inguinal and umbilical hernia cases were not included. Postoperative sepsis occurred in 74 patients (12.8% of all children with laparotomy); in 51 cases positive bacteriological findings were seen besides the clinical and clinicochemical ones. Sepsis morbidity was particularly high in children who had not yet completed their first year of life (postoperative sepsis occurring in approximately every fourth infant); among the disease patterns, the following were particularly prominent: Defects of the abdominal wal…
The interval since first symptoms until diagnosis of squamous cell carcinoma in the head and neck region is still a problem in southern Brazil.
2020
Background The aim was to examine the interval since first symptoms until final diagnosis of squamous cell carcinoma (SCC) in the head and neck region in southern Brazil. Material and Methods The individuals were prospectively selected and underwent anamnesis, physical examination and interview in the first medical consultation at a Cancer Hospital from south of Brazil. Results From 488 patients who underwent clinical examination, 105 were included in the study with diagnosis of SCC. Patients average interval from first symptoms to final diagnosis was 152 days (median 86; max:1105; min: 1), the average professional interval was 108 days (median: 97; max:525; min: 1) , and the average total …
Recent Exploits of the ISOLTRAP Mass Spectrometer
2013
Abstract The Penning-trap mass spectrometer ISOLTRAP, located at the isotope-separator facility ISOLDE (CERN), is presented in its current form taking into account technical developments since 2007. Three areas of developments are presented. The reference ion sources have been modified to guarantee a sufficient supply of reference ions for mass measurements and systematic studies. Different excitation schemes have been investigated for manipulation of the ion motion in the Penning trap, to enhance either the purification or measurement process. A multi-reflection time-of-flight mass separator has been implemented and can now be routinely used for purification and as a versatile tool for bea…
Characterization of antigenic epitopes of potato virus Y.
1993
Immunochemical analysis of overlapping synthetic hexapeptides covering the entire length of the coat protein of potato virus Y (PVY) revealed immunodominant regions both at the N-terminal and at the C-terminal end of the coat protein. Immunization of rabbits with synthetic peptides representing N- and C-terminal regions of the coat protein resulted in production of antibodies that reacted with PVY. Antigenicity of PVY peptides was found to correlate with predicted beta turns, with hydrophilicity and with predicted chain flexibility. Characterization of the immunochemical properties of PVY will facilitate the development of detection methods for potyviruses.
La educación auditiva como eje vertebrador de la educación musical en la Educación Secundaria Obligatoria
2013
El presente trabajo se enmarca dentro de un estudio de mayores dimensiones motivado por el interés de los autores en la didáctica de la audición musical, convencidos de que los principios fundamentales sobre los que se debería apoyar la educación musical actualmente en la Educación Secundaria Obligatoria son, por una parte, la necesidad de una mayor contribución de la misma a una educación integradora de todas las dimensiones del ser humano, y por otra, la conveniencia de otorgarle un mayor protagonismo a la educación auditiva en el proceso de enseñanza-aprendizaje de la materia de música en dicha etapa educativa. El propósito es dar respuesta a una serie de interrogantes que surgen en torn…
