Dynamic changes in the subcellular distribution of the tobacco ROS-producing enzyme RBOHD in response to the oomycete elicitor cryptogein.
2014
Highlight text The oomycete elicitor cryptogein triggers the relocation of RBOHD from intracellular compartments to the plasma membrane in tobacco cells. This suggests that intracellular trafficking is a potential determinant of RBOHD activity.
Deployment of the ATLAS high level trigger
2005
The ATLAS combined test beam in the second half of 2004 saw the first deployment of the ATLAS high-level triggers (HLT). The next steps are deployment on the pre-series farms in the experimental area during 2005, commissioning and cosmics tests in 2006 and collisions in 2007. This paper reviews the experience gained in the test beam, describes the current status and discusses the further enhancements to be made. We address issues related to the dataflow, selection algorithms, testing, software distribution, installation and improvements
CD95 death-inducing signaling complex formation and internalization occur in lipid rafts of type I and type II cells
2004
We investigated the membrane localization of CD95 in type I and type II cells, which differ in their ability to recruit and activate caspase-8. We found that CD95 was preferentially located in lipid rafts of type I cells, while it was present both in raft and non-raft plasma membrane sub-domains of type II cells. After stimulation, CD95 located in phospholipid-rich plasma membrane was recruited to lipid rafts in both types of cells. Similarly, CD95 cross-linking resulted in caspase-independent translocation of FADD/MORT1 and caspase-8 to the lipid rafts, which was prevented by a death domain-defective receptor. CD95 internalization was then rapid in type I and delayed in type II cells and s…
La crisis gremial y los problemas de la sedería valenciana (finales del siglo XVIII y principios del siglo XIX)
1992
La reforma del sistema gremial alcanza una de sus medidas más radicales con la abolición de los gremios de torcedores de seda en 1793. En estas páginas se analiza la medida abolicionista en el marco general de los problemas de la sedería valenciana. En la misma, la hilatura, de la que el torcido es su fase superior y última, había llegado a constituirse en un cuello de botella que comprometía su futuro. En los años aquí contemplados, se proponen y ensayan diversas alternativas que solucionen las disfunciones que generaba la peculiar división del trabajo que obraba en la sedería. La no implicación del capital comercial de la ciudad en la necesaria reconversión de la hilatura será un factor c…
Communist Authorities Contra Brother Kloc. The Battlefront Against The Illegal Trade of Devotional Items in The Koźle District In 1965
2019
W artykule przedstawiony został casus jednego z zakonników Kościoła Katolickiego. Zdaniem autora przypadek ten dobrze ilustruje realia, w jakich przyszło żyć duchowieństwu w Polskiej Rzeczypospolitej Ludowej. Wojciech Kloc, ze Zgromadzenia Braci Albertynów, prowadził handel dewocjonaliami w celu zarobienia pieniędzy na remont dachu domu zakonnego. Z tego powodu został zatrzymany przez milicję przed jednym z kościołów w Kędzierzynie (powiat kozielski), gdzie odebrano mu dewocjonalia, którymi handlował oraz pieniądze, które przy nim znaleziono. Czyn, którego się dopuścił zakonnik, został zakwalifikowany jako przestępstwo w świetle ustawy z 1958 r. o zezwoleniach na wykonywanie przemysłu, rzem…
Effects of a local single dose administration of growth hormone on the osseointegration of titanium implants.
2021
The aim of the present study was to evaluate the effect of different concentrations of growth hormone (GH) on endosteal implant?s surface at the early stages of osseointegration. Sixty tapered acid-etched titanium implants were divided into four groups: i) Collagen, used as a control group; and three experimental groups, where after collagen coating, GH was administered directly to the surface in varying concentrations: ii) 0.265 mg, iii) 0.53 mg, and iv) 1 mg. Implants were placed in an interpolated fashion in the anterior flange of C3, C4 or C5 of 15 sheep with minimum distance of 6 mm between implants. After 3-, 6- and 12-weeks of healing samples were harvested, histologically processed,…
Bone regeneration using particulate grafts : an update
2010
Objective: A review is made of the publications on bone regeneration using particulate grafts, with an evaluation of the success of implants placed in such regenerated areas. Material and Method: A Medline search using different key words was made of the articles published between 1999-2009 involving at least two patients subjected to grafting with autologous, homologous or xenogenic bone, non-bony substitutes, or a combination of these grafts for the placement of dental implants. Studies involving block grafting were excluded. A total of 11 studies were evaluated. Results: These grafts are indicated in cases of small or peri-implant bone defects such as dehiscences and fenestrations, with …
Upconversion nanoparticles with a strong acid-resistant capping
2016
Water-dispersible upconversion nanoparticles (β-NaYF:Yb,Er, UCNP) coated with a thin shell of a biocompatible copolymer comprising 2-hydroxyethylmethacrylate (HEMA) and 2-acrylamido-2-methyl-1-propanesulphonsulphonic acid (AMPS), which we will term COP, have been prepared by multidentate grafting. This capping is remarkably resistant to strong acidic conditions as low as pH 2. The additional functionality of the smart UCNP@COP nanosystem has been proved by its association to a well-known photosensitizer (namely, methylene blue, MB). The green-to-red emission ratio of the UC@COP@MB nanohybrid exhibits excellent linear dependence in the 7 to 2 pH range as a consequence of the release of the d…
Rehabilitation of the severely atrophied dentoalveolar ridge in the aesthetic region with corticocancellous grafts from the iliac crest and dental im…
2016
Background The aim of this study was to assess changes in bone volume after block bone augmentation and placement of dental implants and further evaluate the aesthetic outcome of the treatment. Material and Methods 9 Patients with atrophied anterior maxilla were included in this study. They received total of 21 implants. Dimensions of the alveolar ridge were measured from cone-beam computed tomography x-rays. The bone level at the implant sites was analysed from intraoral x-rays and the aesthetic outcome was assessed from clinical photographs using a pink aesthetic score (PES) scaling. Results The mean gained horizontal bone width at the marginal crest and 5 mm apically was accordingly 2.7m…
The Aspects of the Development of Children Speech in their Constructive Activity
2015
One of the most important task of the pre – school pedagogical process is to promote the development of the chidren thinking and imagination. One of the method is the constructive activity whick aim is to develop the children abstractive thinking and imagination. Constructive activity concerns several children processes of cognition, it promotes the perceptivities, thinking, imagination, understanding of the environment, it makes the child to think of the colours, shapes and connections of the items. Construction promotes the development of the speech, it introduces children with mathematical conceptions and the base of geometry. Wider conceptions and understanding about the construction ac…
