Improving the cementation of the tibial component in knee arthroplasty : a study of four techniques in the cadaver.
2021
Aims The main objective of this study is to analyze the penetration of bone cement in four different full cementation techniques of the tibial tray. Methods In order to determine the best tibial tray cementation technique, we applied cement to 40 cryopreserved donor tibiae by four different techniques: 1) double-layer cementation of the tibial component and tibial bone with bone restrictor; 2) metallic cementation of the tibial component without bone restrictor; 3) bone cementation of the tibia with bone restrictor; and 4) superficial bone cementation of the tibia and metallic keel cementation of the tibial component without bone restrictor. We performed CT exams of all 40 subjects, and mea…
Development of the first marmoset-specific DNA microarray (EUMAMA): a new genetic tool for large-scale expression profiling in a non-human primate
2007
Abstract Background The common marmoset monkey (Callithrix jacchus), a small non-endangered New World primate native to eastern Brazil, is becoming increasingly used as a non-human primate model in biomedical research, drug development and safety assessment. In contrast to the growing interest for the marmoset as an animal model, the molecular tools for genetic analysis are extremely limited. Results Here we report the development of the first marmoset-specific oligonucleotide microarray (EUMAMA) containing probe sets targeting 1541 different marmoset transcripts expressed in hippocampus. These 1541 transcripts represent a wide variety of different functional gene classes. Hybridisation of …
Evaluation of efficacy and biocompatibility of a new absorbable synthetic substitute as a dural onlay graft in a large animal model.
2016
Numerous dura substitutes are commercially available, but no absorbable synthetic dura repair product has been used for both onlay and suture applications.The safety and effectiveness of a new absorbable synthetic substitute composed of Poly-L-lactide microfibers as onlay dural graft were evaluated.Physical properties and performance of the microfibrous synthetic dural substitute implanted as an onlay or suturable grafts were compared with these commercial products, including CODMAN ETHISORB™ Dura Patch and DuraGen™ Dural Graft Matrix, in a canine duraplasty model. The cerebrospinal fluid (CSF) leakage, macroscopic and microscopic observation at 30 and 90 days after implantation were invest…
The effect of cement fixation on initial micromotion of the femoral component in condylar knee replacement
1992
Four fresh, cadaveric specimens were fitted with total knee replacements and mounted on a knee joint loading and measuring rig. Femoral component micromotion in the sagittal plane was measured with a transducer during flexion and extension of the specimen. Various condylar designs were used without and with cement. Movement followed a characteristic curve pattern and was less with cement fixation particularly for bone of low trabecular strength as determined by bone sample tests for stiffness. Cement fixation appears to be superior to cementless fixation.

Artykuł zawiera opis wybranych metod poznawczo-behawioralnych wykorzystywanych w pracy z wymagającą wsparcia młodzieżą z zaburzeniami ze spektrum autyzmu (ASD L1). We wstępie opisano pokrótce historię zaburzenia i podstawowe problemy występujące u dzieci i młodzieży ze spektrum zaburzeń autystycznych. W dalszej części przytoczono informacje na temat technik poznawczo-behawioralnych często stosowanych w pracy z tymi adolescentami. Omówiono przykładowe programy treningów umiejętności społecznych: PEERS (Program for the Education and Enrichment of Relationship Skills) oraz MASSI (Multimodal Anxiety and Social Skills Intervention). Przybliżono dwa programy wykorzystywane w pracy nad rozwijaniem…

Zapobieganie stosowania technik neutralizacji jako zadanie wychowawcze
2017
Autorka w niniejszym artykule zwraca uwagę na zjawisko i mechanizmy usprawiedliwiania własnego zachowania z perspektywy psychologii poznawczej, psychologii społecznej i koncepcji kryminologicznej Sykesa i Matzy. Usprawiedliwianie własnego działania, jeśli skutecznie neutralizuje uczucia moralne, utrudnia jednostce uczenie się na własnych błędach, co prowadzi do powtarzania zachowań niezgodnych z normami społecznymi i prawnymi. To prosta droga do przestępczości. Dlatego rolą pedagogów je s t niedopuszczenie by dzieci i młodzież uczyli się sprawnych technik neutralizacji.
Educational attainment and permanence in NEET situation among youth
2018
Using the French Labour Force Survey, this paper analyses the individual and institutional effects on the transitions into and out of NEET status before and after the crisis. In particular, we question whether the profiles or the labour market transition patterns of young people have changed since the economic crisis. The econometric results indicate that the NEET risks vary according to age, sex, educational level and social origins. They also show that the transition out of NEET status is more related to the educational attainment, after 2008. Conversely, the lack of human capital and social capital increases the retention of youth in NEET situations.
Latest Developments and Results of Radiation Tolerance CMOS Sensors with Small Collection Electrodes
2020
The development of radiation hard Depleted Monolithic Active Pixel Sensors (DMAPS) targets the replacement of hybrid pixel detectors to meet radiation hardness requirements of at least 1.5e16 1 MeV neq/cm2 for the HL-LHC and beyond. DMAPS were designed and tested in the TJ180 nm TowerJazz CMOS imaging technology with small electrodes pixel designs. This technology reduces costs and provides granularity of 36.4x36.4 um2 with low power operation (1 uW/pixel), low noise of ENC < 20 e-, a small collection electrode (3 um) and fast signal response within 25 ns bunch crossing. This contribution will present the latest developments after the MALTA and Mini-MALTA sensors. It will illustrate the imp…

In the present world International tourism is one of the most quickly and dynamically developing sectors of economy. In the year 2012 - for the first time in the history of humankind - international tourist arrivals exceeded one billion tourists globally; and within merely 20 years’ time, i.e. between 1995 and 2015, the number of people travelling abroad as tourists more than doubled. The phenomenon also refers to the inbound tourism in Poland - with more than 16 million international tourists who visited our country in 2015. Obviously, on the one hand, the fact is highly beneficial for the country's international prestige and economy, but on the other hand, it does create certain challenge…
