Despite the synergy of immune checkpoint blockade(ICB) therapy and photodynamic therapy(PDT) holds great promise as countermeasures against breast cancer, exploring long-term or flexible short-time therapeutic strategies in “cold” tumors remains a great challenge. Here, we present a polyunsaturated fatty acid-doped liposomal hydrogel Lp(DHA)@CP Gel loaded with photosensitizer chlorin e6(Ce6) and programmed death-ligand 1 antibody(αPD-L1) for flexible local photoimmunotherapy with merely singledosed administration. The presence of polyunsaturated fatty acid(docosahexaenoic acid, DHA) doped in particle membrane endows liposomes with flexibly reactive oxygen species(ROS)-responsive release capability, which was attributed to the presence of abundant unsaturated groups. The αPD-L1 was repeatedly induced to in situ release in response to the PDT under photo-exposure. The immunogenic cell death(ICD) effect of PDT evoked “cold” breast tumor to “hot” one, and then assisted the cascade releasedαPD-L1 to synergistically boost the immunotherapy. After a single dose of peritumoral administration of Lp(DHA)@CP Gel, the on-demand treatment can maximize patient compliance and safety by adjusting therapeutic behaviors via a photo on-off switch. This work presents a flexible medication platform,showing promise in improving the objective response rate of ICB therapy and minimizing its systemic toxicity.

Paragangliomas,also known as pheochromocytomas(1–9 cases per million),arise in the paraganglia.[1]Pheochromocytomas occur in the adrenal glands,while paragangliomas occur elsewhere.[2]Paragangliomas originate from paraganglion cells,which are derived from the neural ectoderm of the nerves and migrate along both sides of the median axis from the base of the skull to the pelvis during embryonic development.

Diamondoids in petroleum: a review of sources and thermal evolution

引用

Journal of Earth Science 2024年

作者： Biqing zhu Quanyou Liu Huiyuan Xu Dongya zhu Qingqiang meng Jingbin Wang Institute of Energy， Peking University Petroleum Exploration and Production Research Institute SINOPEC

Cage structural diamondoids serve as highly stable molecular indicators， extensively employed in delineating the hydrocarbon sources， particularly in light oils and condensates found in ultra-deep reservoirs. A systematic summary of thermal pyrolysis experiments suggested that the thermal evolution of diamondoids in petroleum consists of four distinct stages: (1) birth， (2) growth and enrichment， (3) decrease and decomposition， and (4) complete decomposition. The diamondoids are mainly sourced from the thermal cracking of oil during the late catagenesis to metagenesis， followed by kerogen maturation during catagenesis. Considering the diamondoid decomposition for the first time， we propose an evolution model of diamondoids during hydrocarbon generation in actual reservoirs， which is much more significant in revealing the primary sources and secondary processes (e.g.， evaporation fractionation) of ultra-deep hydrocarbons. In addition， this model enables us to determine the baseline and predict the ‘dead line’ for preserving liquid hydrocarbons in ultra-deep reservoirs. However， the transformation mechanisms between diamondoids and other molecular markers in deep basins need to be further investigated.
