Self-doping TiO2 has recently attracted considerable attention for its high photocatalytic activity under visible-light irradiation. However, the literature reported synthetic methods until now were very time-consuming. In this study, we establish a quick and facile method for obtaining self-doping TiO2 with the use of directly treated commercial P25 at a desired temperature for only 5 min thro...
UNLABELLED Most plant viruses counter the RNA silencing-based antiviral defense by expressing viral suppressors of RNA silencing (VSRs). In this sense, VSRs may be regarded as virulence effectors that can be recognized by the host as avirulence (avr) factors to induce R-mediated resistance. We made use of Agrobacterium-mediated transient coexpression of VSRs in combination with Potato virus X (...
CD4+ Th1 cells play a critical role in the induction of cell-mediated immune responses that are important for the eradication of intracellular pathogens. Peptide-25 is the major Th1 epitope for Ag85B of Mycobacterium tuberculosis and is immunogenic in I-Ab mice. To elucidate the role of the TCR and IFN-gamma/IL-12 signals in Th1 induction, we generated TCR transgenic mice (P25 TCR-Tg) expressin...
TPPP/p25 is a microtubule-associated protein, detected in protein inclusions associated with various neurodegenerative diseases. Deletion analysis data show that TPPP/p25 has two microtubule binding sites, both located in intrinsically disordered domains, one at the N-terminal and the other in the C-terminal domain. In copolymerization assays the full-length protein exhibits microtubule stimula...
Different mechanisms of CDK5 and CDK2 activation as revealed by CDK5/p25 and CDK2/cyclin A dynamics.
A detailed analysis is presented of the dynamics of human CDK5 in complexes with the protein activator p25 and the purine-like inhibitor roscovitine. These and other findings related to the activation of CDK5 are critically reviewed from a molecular perspective. In addition, the results obtained on the behavior of CDK5 are compared with data on CDK2 to assess the differences and similarities be...
Highly crystalline mesoporous anatase TiO₂ nanospheres with high surface area (higher than P25 and anatase TiO₂) are prepared by a soft-template method. Despite the high specific surface area, these samples have three times lower equilibrium adsorption (<2%) than Degussa P25. The rate constant of the mesoporous anatase TiO₂ (0.024 min-1) reported here is 364% higher than that of P25 (0.0066 min...
چکیده تخریب فوتوکاتالیزوری داروی کاربامازپین توسط tio2-p25 در حضور نور uv مطالعه شد و پارامترهای سینتیکی آن به دست آمد. تأثیر عوامل مختلف بر فرآیند نظیر جرم فوتوکاتالیزور، غلظت اولیه دارو، ph، دما، غلظت اکسیژن و آب اکسیژنه در محیط مطالعه گردید. مقایسه نتایج به دست آمده با داده-های حاصل از تأثیر فوتوکاتالیزور tio2 و tio2-nio تهیه شده در ابعاد نانو نشان داد که حجم حفرات فوتوکاتالیزور تأثیر به ...
In plants, viruses induce an RNA-mediated defense that is similar to posttranscriptional gene silencing (PTGS) of transgenes. Here we demonstrate with potato virus X (PVX) that PTGS operates as a systemic, sequence-specific defense system. However, in grafting experiments or with movement defective forms of PVX, we could not detect systemic silencing unless the 25 kDa viral movement protein (p2...
