We used delivery mode (augmented vaginal deliveries and nonelective cesarean deliveries) as a surrogate for intrapartum stress, which is known to alter cord blood thyroid hormones.
A spontaneous onset of delivery was defined by the presence of initial signs of delivery (contractions, bleeding, preterm premature rupture of membranes [PPROM], or painless cervical dilation), but contractions may be augmented and delivery may be by cesarean section.
Because of the tiny particle size, PFC emulsions readily perfuse in the microcirculation, resulting in augmented oxygen delivery to the tissues more effectively than oxygen-carrying blood cells in the large vessels [9].
Cell proliferation and clonogenic examinations showed that β-cyclodextrin-curcumin self-assembly augmented curcumin delivery and improved its therapeutic efficacy in prostate cancer cells [ 55].
This might be explained by an augmented oxygen delivery through very narrow capillaries where Oxygent particles may penetrate better than the relatively large red blood cells, and thereby improve local tissue oxygenation more than red blood cells [ 1].
In particular, targeting patients who are most likely to benefit from augmented nutritional delivery and who will require nutritional support for a substantial period of time will be a priority.
We hypothesize that augmented cellular delivery of the nanoparticles, which is known to increase with increasing surface roughness and/or loss of anionic surface charge, occurs as a result of the previously described pH-dependent structural changes.
The fact is that the respiratory pump does not have an unlimited capacity; if it did, theoretically, some patients would require augmented oxygen delivery and/or end expiratory pressure but none would require MV.
This hypoxic pH-responsive behavior is characterized by hydrodynamic swelling, a loss in stabilizing surface charge, and a decrease in apparent surface energy that correlates with augmented cellular delivery to both 2D and 3D cell cultures, as well as in vivo co-localization with hypoxia-inducible factor 1 α in murine tumor models of triple-negative breast carcinoma.
Indeed, an NSAID has been shown to increase ectopic expression of IL-24 that augmented adenovirus delivery leading to the proposed use of more than one inducer of IL-24 to achieve superphysiological levels of this pro-apoptotic factor in tumors [ 35].
