Microbubbles, ultrasound contrast agents currently in development as ultrasonically activated drug delivery vehicles, were studied using a novel flow cell design.
This article aims at reviewing the various microbially activated drug delivery systems for colon-specific drug delivery with specific reference to the microflora of the various segments of the gastrointestinal tract and their role in targeting drug delivery to the colon.
We hypothesize that sonoporation plays an important role in the acoustically activated drug delivery of chemotherapy drugs delivered from Pluronic micelles.
The culture level was maintained at 1.7 L with use of a level controller (AppliSens APS501 level controller), which activated the delivery of fresh medium to the bioreactor via the feed pump when necessary.
This study has shown that cationic liposome and polyplex carriers used for nonviral gene delivery activate autophagy.
The processes activated for lysosome delivery have defined three types of autophagy: macroautophagy, microautophagy, and chaperone-mediated autophagy.
Once the C-terminal glycine of LC3B is exposed by ATG4B, ATG7 in an ATP-dependent manner activates LC3B for delivery to ATG3, which conjugates LC3B to phosphatidylethanolamine.
Purified pilin introduced into mouse macrophages by liposomal delivery activated caspase-1 and led to secretion of mature IL-1β, as did recombinant pilin purified from Escherichia coli.
ALP) activity using yeast strains carrying an engineered form of PHO8 (pho8ΔN60), encoding a cytosolically localized phosphatase, which becomes activated through autophagic delivery to the vacuole (Noda and Klionsky, 2008).
For example, one study found that while anticipation of pain (psychological stress) activated emotion-arousal structures, delivery of pain resulted in activation of visceral afferent processing structures as well as cortical modulation of structures in frontal and parietal cortices [43].
All these initiatives will meet in Davos this week to help activate a new global delivery agenda.
