  The invention provides a (drug-containing) lipid nanoparticle with: (i) at least one phospholipid; (ii) at least one lysolipid; and (iii) at least one phospholipid comprising a hydrophilic polymer;and (iv) at least one structural lipid of formula (I) which has the following general structure: (I) wherein R and R' are long hydrocarbyl hydrophobic chains, Y is a linker element, and PHG is a polar head group described as large according to its van der Waals radius, and which is different from the phospholipid (i). The lipid nanoparticle can release a drug (or API) from within the lipid nanoparticleas a result of focussed ultrasound (FUS) applied continuously, at least twice, to a desired part of the body to induce hyperthermia (an increase in temperature). FUS is applied after the lipid nanoparticle containing the drug has been administered to the live subject, and causes controlled release of the drug at the desired site of the body. Ultrasound is then halted, and the site of interest allowed to cool. Ultrasound is then applied again. Lipidnanoparticles can be labelled (for MRI, NIRF imaging),enablin greal time monitoring of the drug in the human body. Imaging information can be used to direct and guide the nature of the FUS applied to the site of interest.

  本发明提供了一种（含药物的）脂质纳米粒子，其包含：（i）至少一种磷脂；（ii）至少一种溶血磷脂；（iii）至少一种包含亲水性聚合物的磷脂；以及（iv）至少一种结构脂质，其具有以下一般结构式（I）：（I）其中R和R'是长的烃基疏水链，Y是连接元素，PHG是极性头基，根据其范德华半径描述为大，且不同于磷脂（i）。脂质纳米粒子可以通过聚焦超声（FUS）在体内所需部位连续施加至少两次，诱导体温升高（发热），从而释放药物（或API）从脂质纳米粒子内部释放。在给活体主体注入含药物的脂质纳米粒子后，施加FUS会导致药物在体内所需部位的受控释放。然后停止超声，让感兴趣的部位冷却。然后再次施加超声。脂质纳米粒子可以被标记（用于MRI、NIRF成像），从而实现对人体内药物的实时监测。成像信息可以用于指导和引导施加于感兴趣部位的FUS的性质。

  The present invention inter alia provides a method, and use thereof, of predicting CV events such as AMI, ACS, stroke, and CV death by determining the concentration of at least one ceramide of Formula I or one lysophospholipid of Formula II and/or III and at least one lysophospholipid of Formula IV, V, VI, VII and/or VIII in a biological sample and comparing those concentrations to a control. Finding an increased concentration of the at least one Formula I ceramide or Formula II and/or III lysophospholipid and a decreased concentration of the at least one Formula IV, V, VI, VII and/or VIII lysophospholipid indicates that the subject has an increased risk of developing one or more CV events. The present disclosure also provides a method, and use thereof, of diagnosing subjects suffering acute ischemia. Also provided are kits and compositions comprising the same for use in predicting and/or diagnosing CV events.
