The major obstacle to clinical development of siRNAs (short interfering RNAs), like for most of the nucleic-acid-based strategies, is their poor cellular uptake and bioavailability. Although several viral and non-viral strategies have been proposed to improve siRNA delivery, their applications in vivo remain a major challenge. We have developed a new strategy, based on a short amphipathic pepti...

Abstract Atomically monodispersed heterogeneous catalysts with uniform active sites and high atom utilization efficiency are ideal catalytic materials. Designing such type of catalysts, however, remains a formidable challenge. Herein, using wet-chemical method, we successfully achieved mesoporous graphitic carbon nitride (mpg-C 3 N 4 ) supported dual-atom Pt 2 catalyst, which exhibited excellen...

The development of short interfering RNA (siRNA), has provided great hope for therapeutic targeting of specific genes responsible for pathological disorders. However, the poor cellular uptake and bioavailability of siRNA remain a major obstacle to their clinical development and most strategies that propose to improve siRNA delivery remain limited for in vivo applications. In this study, we repo...

BACKGROUND Advanced stage cancer treatments are often invasive and painful-typically comprised of surgery, chemotherapy, and/or radiation treatment. Low transport efficiency during systemic chemotherapy may require high chemotherapeutic doses to effectively target cancerous tissue, resulting in systemic toxicity. Nanotherapeutic platforms have been proposed as an alternative to more safely and ...

BACKGROUND Valve effective orifice area EOA and transvalvular mean pressure gradient (MPG) are the most frequently used parameters to assess aortic stenosis (AS) severity. However, MPG measured by cardiovascular magnetic resonance (CMR) may differ from the one measured by transthoracic Doppler-echocardiography (TTE). The objectives of this study were: 1) to identify the factors responsible for ...

We discuss the application of heterogeneous metaprogramming (MPG) for the interfacebased design, which deals with the synthesis of the communication interfaces between Intellectual Property components (IPs). Heterogeneous MPG is based on the simultaneous usage of a domain language for describing domain functionality and a metalanguage for developing generic components and program generators. We...

The direct synthesis of TiN nanoparticles on carbon black (CB) was achieved using an mpg-C(3)N(4)/CB composite as a template. The obtained TiN/CB composites ensured improved contact between TiN and CB, functioning as an efficient cathode catalyst for oxygen reduction reaction (ORR) in polymer electrolyte fuel cells (PEFCs). The preparation procedure developed in this study is applicable for the...

N-methylpurine DNA glycosylase (MPG), a DNA repair enzyme, functions in the DNA base excision repair (BER) pathway. Aberrant over-expression of MPG in various cancers suggests an important role of MPG in carcinogenesis. Identification of MPG-interacting proteins will help to dissect the molecular link between MPG and cancer development. In the present study, using immunoprecipitation coupled wi...
