Abstract
Atherosclerosis is a chronic inflammatory vascular disease that is characterized by the accumulation of lipids and immune cells in plaques built up inside artery walls. Docosahexaenoic acid (DHA, 22:6n-3), an omega-3 polyunsaturated fatty acid (PUFA), which exerts anti-inflammatory and antioxidant properties, has long been purported to be of therapeutic benefit to atherosclerosis patients. However, large clinical trials have yielded inconsistent data, likely due to variations in the formulation, dosage, and bioavailability of DHA following oral intake. To fully exploit its potential therapeutic effects, we have developed an injectable liposomal DHA formulation intended for intravenous administration as a plaque-targeted nanomedicine. The liposomal formulation protects DHA against chemical degradation and increases its local concentration within atherosclerotic lesions. Mechanistically, DHA liposomes are readily phagocytosed by activated macrophages, exert potent anti-inflammatory and antioxidant effects, and inhibit foam cell formation. Upon intravenous administration, DHA liposomes accumulate preferentially in atherosclerotic lesional macrophages and promote polarization of macrophages towards an anti-inflammatory M2 phenotype, resulting in attenuation of atherosclerosis progression in both ApoE-/- and Ldlr-/- experimental models. Plaque composition analysis demonstrates that liposomal DHA inhibits macrophage infiltration, reduces lipid deposition, and increases collagen content, thus improving the stability of atherosclerotic plaques against rupture. Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) further reveals that DHA liposomes can partly restore the complex lipid profile of the plaques to that of early-stage plaques. In conclusion, DHA liposomes offer a promising approach for applying DHA to stabilize atherosclerotic plaques and attenuate atherosclerosis progression, thereby preventing atherosclerosis-related cardiovascular events.

Abstract
Abstract
Background
Lipidome disturbance has long been recognized to occur after myocardial infarction (MI). Accumulation of excessive fatty acids induces production of reactive oxygen species and consequently deteriorates cardiac injury in MI. However, the spatial and temporal lipid profile in the heart following ischemic injury remains unknown.
Purpose
We aim to uncover the temporal-spatial lipidome profile of the heart following ischemia reperfusion (I/R) injury and identify circulating lipids released from injured myocardium that are potentially useful for diagnosis of ischemic heart disease.
Methods
C57/BL6 mice were subjected to 30 min myocardial ischemia followed by removal of the ligature to establish reperfusion injury. Porcine I/R injury was induced by 105 min myocardial ischemia followed by reperfusion. Human plasma was obtained from 143 post-MI patients. Myocardial lipid profiles were generated by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MALDI-MSI) in different regions (infarct, remote and peri-infarct) at different time points. Moreover, the lipids in the heart and plasma were analysed by LC-MS/MS.
Results
We observed a drastic alteration in the lipidome with distinct spatial-temporal features in the injured heart by both MALDI-MSI and LC-MS/MS. In the infarct heart tissue, as revealed by LC-MS/MS, we observed an elevation of glycerolipids that peaked at 3 hours after I/R, and a sustained elevation of phospholipids and sphingolipids up to 3 days. Similar alternations in lipid profile was observed but much weaker in the remote and peri-infarct heart tissue compared to the infarct tissue. Among those lipids, PC 32:0 detected by MALDI-MSI highly overlapped CD68 staining at a single-cell level, showing a strong correlation of PC 32:0 with macrophage infiltration in mouse hearts (R2=0.93, p<0.0001). A similar increase of PC 32:0 in the infarct area was also observed in porcine hearts following I/R injury. Surprisingly, plasma levels of PC 32:0 in the mice decreased after I/R injury. In humans, plasma levels of PC 32:0 in post-MI patients were lower than that in healthy individuals (p=0.03). Further analysis demonstrated that plasma levels of PC 32:0 determined within 72 hours after percutaneous coronary intervention were negatively correlated with the 6-month post-MI cardiac ejection fraction in patients (R2=0.08, p<0.001).
Conclusions
A temporal-spatial lipidome profile was established in heart injury by synergizing LC-MS/MS and mass spectrometry imaging. PC 32:0 levels are positively correlated with myocardial macrophage infiltration but negatively correlated with cardiac function in cardiac I/R injury. Our findings indicate that PC 32:0 is a potential biomarker for cardiac injury and the inflammatory status in the injured heart.

Abstract
INTRODUCTION Peritoneal carcinomatosis is difficult to treat. Pressurized Intra-Peritoneal Aerosolised Chemotherapy (PIPAC) is a novel method of delivering chemotherapy to the peritoneal cavity, aiming for homogenous and deeper drug distribution. To date, limited chemotherapeutics have been used with promising results. Here, we evaluate the pharmacokinetics, peritoneal tissue drug concentration, penetration, and short-term safety of PIPAC using solvent-based paclitaxel in swine to guide clinical trials. MATERIALS AND METHODS PIPAC solvent-based paclitaxel was administered at 60, 30, and 15mg/m2 for 3 cohorts. Each PIPAC procedure was followed by intravenous (IV) administration of the same dose of solvent-based paclitaxel on Day 7, serving as control for pharmacokinetic comparison in the same pig. Safety and toxicity were evaluated by clinical assessment, blood counts and biochemistry. Blood samples were taken for pharmacokinetic analysis. Peritoneal biopsies were taken to measure tissue paclitaxel concentrations and distribution. RESULTS 12 Yorkshire x Landrace pigs underwent trial procedures. With PIPAC, there was linear pharmacokinetics and lower systemic exposure to paclitaxel compared to IV administration. MALDI-MSI demonstrated concentration of paclitaxel at the peritoneal surface, with estimated 2 mm penetration. PIPAC paclitaxel had favorable toxicity profile. The most significant adverse event was neutropenia which was dose dependent, with absolute neutrophil count <1.0 × 103/μL seen at the highest dose. One pig developed grade 2 hypersensitivity reaction during IV infusion and one death occurred during the PIPAC procedure, likely from anaphylaxis; these are known potential adverse events mandating standard precautions and monitoring. CONCLUSION PIPAC paclitaxel at 15mg/m2 may be considered for a Phase I study.
