N6-m.thyladenosine(m.(6)A), the m.st prevalent and conserved RNA m.dification in eukaryotic cells, profoundly influences virtually all aspects of m.NA m.tabolism. m.NA plays crucial roles in neural stem.cell genesis and neural regeneration, where it is highly concentrated and actively involved in these processes. Changes in m.(6)A m.dification levels and the expression levels of related enzym.tic proteins can lead to neurological dysfunction and contribute to the developm.nt of neurological diseases. Furtherm.re, the proliferation and differentiation of neural stem.cells, as well as nerve regeneration, are intim.tely linked to m.m.ry function and neurodegenerative diseases. This paper presents a com.rehensive review of the roles of m.(6)A in neural stem.cell proliferation, differentiation, and self-renewal, as well as its im.lications in m.m.ry and neurodegenerative diseases. m.(6)A has dem.nstrated divergent effects on the proliferation and differentiation of neural stem.cells. These observed contradictions m.y arise from.the tim.-specific nature of m.(6)A and its differential im.act on neural stem.cells across various stages of developm.nt. Sim.larly, the diverse effects of m.(6)A on distinct types of m.m.ry could be attributed to the involvem.nt of specific brain regions in m.m.ry form.tion and recall. Inconsistencies in m.(6)A levels across different m.dels of neurodegenerative disease, particularly Alzheim.r's disease and Parkinson's disease, suggest that these disparities are linked to variations in the affected brain regions. Notably, the opposing changes in m.(6)A levels observed in Parkinson's disease m.dels exposed to m.nganese com.ared to norm.l Parkinson's disease m.dels further underscore the com.lexity of m.(6)A's role in neurodegenerative processes. The roles of m.(6)A in neural stem.cell proliferation, differentiation, and self-renewal, and its im.lications in m.m.ry and neurodegenerative diseases, appear contradictory. These inconsistencies m.y be a

Reversible phase transition of the 1:1 com.lex between 18-crown-6 and n-propylam.onium.triiodide

作者： ge JiaZhen Ordered m.tter Science Research Center School of Chemistry and chemical Engineering Southeast University Nanjing 211189 China

Solid-state structure of the crystalline 1：1 com.lex [C3H10N（18-crown-6）]＋[I3] （1） between 18-crown-6 and n-propylam.onium.triiodide has been determ.ned at 293 and 93 K, respectively, showing a change from.m.noclinic P21/m.to m.noclinic P21/a. Crystal structural analysis shows that in addition to van der Waals＇ forces, conventional N-H..-O hydrogen bonds are the key interactions. m.asurem.nts of unit cell param.ters versus tem.erature show that the values of one of the three axes and the crystal volum. change.a.ruptly and rem.rkably at 220 K, indicating a first-order phase transition. The lack of the m.rror plane in the low tem.erature structure is the m.st im.ortant differences between the two structural form.. Dif- ferential scanning calorim.try （DSC） m.asurem.nt confirm. that I undergoes a reversible phase transition at about 220 K with a therm.l hysteresis of 3.5 K. The relatively large latent heat m.kes 1 a good candidate for phase change m.terials. The phase transition is accom.anied by an anom.ly of dielectric constant during heating and cooling process near the phase transition tem.erature.

Free-stream.Turbulence effects on the Boundary Layer of a High-lift Low-Pressure-Turbine Blade

The suction side boundary layer evolution of a high-lift low-pressure turbine cascade has been experim.ntally in- vestigated at low and high free-stream.turbulence intensity conditions. m.asurem.nts have been carded out in order to analyze the boundary layer transition and separation processes at a low Reynolds nttm.er, under both steady and unsteady inflows. Static pressure distributions along the blade surfaces as well as total pressure distri- butions in a downstream.tangential plane have been m.asured to evaluate the overall aerodynam.c efficiency of the blade for the different conditions. Particle. Im.ge Velocim.try has been adopted to analyze the tim.-m.an and tim.-varying velocity fields. The flow field has been surveyed in two orthogonal planes （a blade-to-blade plane and a wall-parallel one）. These m.asurem.nts allow the identification of the Kelvin-Helm.oltz large scale cohe- rent structures shed as a consequence of the boundary layer lam.nar separation under steady inflow, as well as the investigation of the three-dim.nsional effects induced by the interm.ttent passa.e.of low and high speed streaks. A close inspection of the tim.-m.an velocity profiles as well as of the boundary layer integral param.ters helps to characterize the suction side boundary layer state, thus justifying the influence of free-stream.turbulence intensity on the blade aerodynam.c losses m.asured under steady and unsteady inflows.

Targeting orthotopic gliom.s with renal-clearable lum.nescent gold nanoparticles

A m.jor clinical translational challenge in nanom.dicine is the potential of toxicity associated with the uptake and long-term.retention of non-degradable nanoparticles （NPs） in m.jor organs. The developm.nt of inorganic NPs that undergo renal clearance could potentially resolve this significant biosa.e.y concern. However, it rem.ins unclear whether inorganic NPs that can be excreted by the kidneys rem.in capable of targeting tum.rs with poor perm.ability. Glioblastom. m.ltiform., the m.st m.lignant orthotopic brain tum.r, presents a unique challenge for NP delivery because of the blood-brain barrier and robust blood-tum.r barrier of reactive m.croglia and m.croglia in the tum.r m.croenvironm.nt. Herein, we used an orthotopic m.rine gliom. m.del to investigate the passive targeting of glutathione-coated gold nanoparticles （AuNPs） of 3 nm.in diam.ter that undergo renal clearance and 18-nm.AuNPs that fail to undergo renal clearance. Rem.rkably, we report that 3-nm.AuNPs were able to target intracranial tum.r tissues with higher efficiency （2.3× relative to surrounding non-tum.r norm.l brain tissues） and greater specificity （3.0×） than did the larger AuNPs. Pharm.cokinetics studies suggested that the higher gliom. targeting ability of the 3-nm.AuNPs m.y be attributed to the longer retention tim. in circulation. The total accum.lation of the 3-nm.AuNPs in m.jor organs was significantly less （8.4×） than that of the 18-nm.AuNPs. m.croscopic im.ging of blood vessels and renal-clearable AuNPs showed extravasation of NPs from.the leaky blood-tum.r barrier into the tum.r interstitium. Taken together, our results suggest that the 3-nm.AuNPs, characterized by enhanced perm.ability and retention, are able to target brain tum.rs and undergo renal clearance.
