Expression of MAP1a and MAP1b in the ganglionic eminence and the internal capsule of the human fetal brain.
2001
The expression of microtubule-associated proteins 1a and 1b (MAP1a and 1b) were investigated in two transient structures, the ganglionic eminence (GE) being a prominent part of the telencephalic proliferative zone and the perireticular nucleus (PR) within the internal capsule (IC). Anti-MAP1a immunolabels PR neurons from 18 weeks of gestation (wg) onwards, whereas anti-MAP1b immunolabels long IC fibers between 18 and 22 wg. MAP1b is further present in thalamic fibers that seem to terminate at the medial margin of the GE, in a moderate number of cells of the GE and its medial extension, the gangliothalamic body (GTB). From 26 to 33 wg MAP1b is expressed in short fiber bundles of the IC, a fe…
Lastenko tiloja? : päiväkotien tilasuunnittelun lähtökohtien yhteys tilasuunnittelussa korostuviin tekijöihin
2017
Tämän tutkimuksen tarkoituksena oli selvittää, millainen yhteys päiväkotien tilasuunnittelun lähtökohdilla on lapsille suunniteltaviin päiväkotitiloihin. Toisena tavoitteena oli tarkastella sitä, millaisia yhtymäkohtia päiväkotien tilasuunnitteluohjeistusten sekä lasten tilapuheen välillä oli havaittavissa. Tutkimuksen kaksiosainen aineisto muodostui kolmen kaupungin päiväkotien tilasuunnitteluohjeistuksista sekä esiopetusikäisiltä lapsilta kerätyistä haastatteluista. Aineiston analyysiin käytettiin soveltaen laadullista sisällönanalyysiä. Tulkinnallisen otteensa vuoksi tutkimuksessa on vahvasti hermeneuttisia piirteitä. Suunnittelun lähtökohdat ovat yhteydessä siihen, millaiset lapsikuvat …
Ferricytochrome c encapsulated in silica hydrogels: correlation between active site dynamics and solvent structure.
2003
Ferricytochrome c encapsulated in silica hydrogels has been prepared by the sol-gel technique following, with some modifications, the procedure originally developed by Ellerby et al. (Science 255 1113 (1992)). A suitable preparation of hydrogels enables having both 'wet' and 'dry' samples. Wet samples have a high water content: as the temperature is lowered below approximately 260 K, water freezes and the samples crack. On the contrary, dry samples have a low water content (hydration h approximately equal 0.35): in these conditions water does not freeze even at cryogenic temperatures and the samples remain transparent and non-cracking. The dynamics of ferricytochrome c and its dependence on…
Effects of salinity and temperature on long-term survival of the eel pathogen Vibrio vulnificus biotype 2 (serovar E)
1999
ABSTRACT Vibrio vulnificus biotype 2 (serovar E) is a primary eel pathogen. In this study, we performed long-term survival experiments to investigate whether the aquatic ecosystem can be a reservoir for this bacterium. We have used microcosms containing water of different salinities (ranging from 0.3 to 3.8%) maintained at three temperatures (12, 25, and 30°C). Temperature and salinity significantly affected long-term survival: (i) the optimal salinity for survival was 1.5%; (ii) lower salinities reduced survival, although they were nonlethal; and (ii) the optimal temperature for survival was dependent on the salinity (25°C for microcosms at 0.3 and 0.5% and 12°C for microcosms at 1.5 to 3.…
A central nervous system-focused treatment approach for people with frozen shoulder: protocol for a randomized clinical trial
2019
Background: Frozen shoulder (FS) is a musculoskeletal condition of poorly understood etiology that results in shoulder pain and large mobility deficits. Despite some physical therapy interventions, such as joint mobilization and exercise, having shown therapeutic benefit, a definitive treatment does not currently exist. The aim of this study will be to compare the effectiveness of a central nervous system (CNS)-directed treatment program versus a standard medical and physical therapy care program on outcomes in participants with FS. Methods/design: The study is a two-group, randomized clinical trial with blinding of participants and assessors. Participants will be recruited via referrals fr…
Soil chemical and biochemical properties of a salt-marsh alluvial Spanish area after long-term reclamation
2009
Marisma, one of the largest salt-marsh alluvial areas in SW Spain, has been reclaimed since 1970 by artificial drainage and amendment with phosphogypsum (PG) so as to reduce Na+ saturation. Within the reclaimed area, two 250- × 20-m plots were treated as follows: (1) amendment with 25 Mg/ha of PG every 2 to 3 years between 1979 and 2003 (plot PY); (2) like PY but PG treatment stopped after 1997 (plot DR). A contiguous virgin Marisma salt-marsh plot (MV), neither drained nor amended, was the control. In MV, soil microbial biomass C, most enzyme activities and total organic C content were much greater than in PY and DR soils, despite the salinity stress. The decrease in soil organic matter co…
Nouvelles stratégies de stabilisation des bactéries extrêmement sensibles à l’oxygène : cas du probiotique Faecalibacterium prausnitzii.
2016
Intestinal bacteria are of growing interest in the areas of health and wellness [1, 3]. The intestinal ecosystem is characterized by its complex composi-tion and its very low oxygen content. Therefore, nu-merous bacterial species isolated from this environ-ment are extremely sensitive to oxygen. This feature is responsible for the difficulty of implementation of these microorganisms for probiotic large-scale appli-cations, particularly during processing and storage. In this presentation, we present the main steps that have been overcome to conserve and design a stabilization strategy for the bacteria Faecalibacterium prausnitzii, recognized for their anti-inflammatory activities intestinal …
Multilayer capsules: a promising microencapsulation system for transplantation of pancreatic islets
2001
In 1980, Lim and Sun introduced a microcapsule coated with an alginate/polylysine complex for encapsulation of pancreatic islets. Characteristic to this type of capsule is, that it consists of a plain membrane which is formed during a single procedural step. With such a simple process it is difficult to obtain instantly a membrane optimized with respect to all the properties requested for islet transplantation. To overcome these difficulties, it is recommended to build up the membrane in several consecutive steps, each optimized for a certain property. In this study, we have analysed such a multilayer microcapsule for the encapsulation of pancreatic islets. Therefore, empty and islet contai…
Unveiling species assemblage rules in gypsum plant communities
2023
Plant communities are not merely snapshots of species located in the same area. Instead, they are dynamic entities connected through complex biotic interactions. Understanding the interplay of processes that bind species within a community is vital for comprehending species maintenance and may assist us in predicting how communities respond to the perturbations of a changing world. This Ph.D. aims to unveil how abiotic conditions, plant strategies, and biotic interactions shape plant communities growing in stressful environments. Plant species can thrive in stressful environments through contrasted strategies, either showing species-specific adaptive strategies or reliance on facilitative i…

Les construccions encapsuladores en anglès i la doble funció en l'emmagatzematge de la informació
 Aquest treball se centra en les propietats funcionals i estructurals d’un tipus de fórmules focals en anglès: les construccions del tipus N-be-that (Schmid 2001), com en The problem is that he is jealous, a les quals denominem fórmules amb encapsuladors (FFSNs, segons la denominació en anglès). La funció dels noms en aquest patró consisteix a crear closques conceptuals (Schmid 1997) dins de les quals s’encapsula el contingut proposicional, una operació afavorida pel vincle coreferencial que hi ha entre les dues parts del patró. Les dades proporcionades pel BNC mostren dues manifestacions …
