An experim.nt was conducted to test the efficacy of a m.chanical barrier around the tree trunk with one spray of Cyperm.thrin @ 1 m./l and turm.ric powder extract @ 15 g/500m. of water applied in integrated approaches against m.ngo m.alybug on m.ngo tree. There were 7 treatm.nts including a control. The treatm.nts were m.chanical barrier, Cyperm.thrin spray @ 1 m./l, Turm.ric powder spray @ 15 g/500m. of water, Cyperm.thrin spray + Turm.ric spray, Cyperm.thrin spray + m.chanical barrier, Turm.ric + m.chanical barrier and untreated control. Three-year-old m.ngo plants grafted from.a 5-year-old m.ngo tree (Variety Am.opali) and planted in pots were used in the experim.nt. The treatm.nt, Cyperm.thrin spray + m.chanical barrier gave the highest reduction of m.ngo m.alybug population 87.06% to 93.90% followed by Turm.ric spray + m.chanical barrier and showed 81.13% to 86.04% and m.chanical barrier alone showed 81.13% to 84.59% population reduction. Turm.ric powder extract showed only (8.42% to 23.77%) population reduction of m.ngo m.alybug which was lowest com.ared to other treatm.nts.

Rem.deling Tum.r Im.une m.croenvironm.nt by Using Polym.r-Lipid-m.nganese Dioxide Nanoparticles with Radiation Therapy to Boost Im.une Response of Castration-Resistant Prostate Cancer

Research 2024年第3期2023卷 83-96页

作者： Abdulm.ttaleb E.zetrini HoYin Lip Azhar z.Abbasi Ibrahim.Alradwan Taksim.Ahm.d Chunsheng He Jeffrey T.Henderson Andrew m.Rauth Xiao Yu Wu Advanced Pharm.ceutics and Drug Delivery Laboratory Leslie Dan Faculty of PharmacyUniversity of TorontoM5S 3M2TorontoONCanada. Departm.nts of m.dical Biophysics and Radiation Oncology University of TorontoM5G 1L7TorontoONCanada.

Despite substantial progress in the treatm.nt of castration-resistant prostate cancer (CRPC), including radiation therapy and im.unotherapy alone or in com.ination, the response to treatm.nt rem.ins poor due to the hypoxic and im.unosuppressive nature of the tum.r m.croenvironm.nt. Herein, we exploited the bioreactivity of novel polym.r–lipid m.nganese dioxide nanoparticles (PLm.s) to rem.del the tum.r im.une m.croenvironm.nt (TIm.) by increasing the local oxygen levels and extracellular pH and enhancing radiation-induced im.unogenic cell death. This study dem.nstrated that PLm. treatm.nt sensitized hypoxic hum.n and m.rine CRPC cells to radiation, significantly increasing radiation-induced DNA double-strand breaks and ultim.tely cell death, which enhanced the secretion of dam.ge-associated m.lecular patterns, attributable to the induction of autophagy and endoplasm.c reticulum.stress. Reoxygenation via PLm.s also polarized hypoxic m.rine RAW264.7 m.crophages toward the m. phenotype, enhancing tum.r necrosis factor alpha release, and thus reducing the viability of m.rine CRPC TRAm.-C2 cells. In a syngeneic TRAm.-C2 tum.r m.del, intravenous injection of PLm.s suppressed, while radiation alone enhanced recruitm.nt of regulatory T cells and m.eloid-derived suppressor cells. Pretreatm.nt with PLm.s followed by radiation down-regulated program.ed death-ligand 1 and prom.ted the infiltration of antitum.r CD8+ T cells and m. m.crophages to tum.r sites. Taken together, TIm. m.dulation by PLm.s plus radiation profoundly delayed tum.r growth and prolonged m.dian survival com.ared with radiation alone. These results suggest that PLm.s plus radiation is a prom.sing treatm.nt m.dality for im.roving therapeutic efficacy in radioresistant and im.unosuppressive solid tum.rs.
