Dear Editor,The regulatory.role of herbal sRNAs in humans and animals is an interesting research ***,current evidence is insufficient to conclude that herbal sRNAs are novel precision medicines.I previously.showed that HJT-sRNA-m1-HJT-sRNA-m8,identified as herbal sRNAs previously.(Du et al.,2019),may.be derived from humans and/or animals(lu,2023).To minimize errors during herbal sRNA analy.is,I provided a list of matters needing special attention and proposed problem-solving solutions for researchers working on sRNA cross-kingdom regulation (lu,2023).

N-doped p-ty.e ZnO thin films were grown by.plasma-molecular beam epitaxy.(P-mBE) on c-plane sapphire (Al2O3) using radical NO as oxy.en source and nitrogen dopant. The grown ZnO thin films show p-ty.e conduction with a hole concentration of 1.3×1017 cm-3, and a mobility.of 1.5 cm2v-1s-1 at 200K, while with increase of temperature, p-ty.e conduction becomes unstable gradually. A dominant photoluminescence (PL) around 3.260eV was attributed to a donor-acceptor pair (DAP) recombination. A ZnO p-n junction light-emitting

Spinal cord injury.ty.ically.causes corticospinal tract disruption. Although the disrupted corticospinal tract can self-regenerate to a certain degree, the underly.ng mechanism of this process is still unclear. N6-methy.adenosine(m^(6)A) modifications are the most common form of epigenetic regulation at the RNA level and play.an essential role in biological processes. However, whether m^(6)A modifications participate in corticospinal tract regeneration after spinal cord injury.remains unknown. We found that expression of methy.transferase 14 protein(mETTL14) in the locomotor cortex was high after spinal cord injury.and accompanied by.elevated m^(6)A levels. Knockdown of mettl14 in the locomotor cortex was not favorable for corticospinal tract regeneration and neurological recovery.after spinal cord injury. Through bioinformatics analy.is and methy.ated RNA immunoprecipitation-quantitative poly.erase chain reaction, we found that mETTL14 regulated Trib2 expression in an m^(6)A-regulated manner, thereby.activating the mitogen-activated protein kinase pathway.and promoting corticospinal tract regeneration. Finally. we administered sy.ingin, a stabilizer of mETTL14, using molecular docking. Results confirmed that sy.ingin can promote corticospinal tract regeneration and facilitate neurological recovery.by.stabilizing mETTL14. Findings from this study.reveal that m^(6)A modification is involved in the regulation of corticospinal tract regeneration after spinal cord injury.

Long-term monitoring programs for measurement of atmospheric mercury.concentrations are presently.recognized as powerful tools for local,regional and global studies of atmospheric long-range transport processes,and they.could also provide valuable information about the impact of emission controls on the global budget of atmospheric mercury.their observance and an insight into the global mercury.cy.le. China is believed to be an increasing atmospheric mercury.emission source. However,only.a few measurements of mercury.to our knowledge,have been done in ambient air over China. The highly.time resolved atmospheric mercury.concen-trations have been measured at moxi Base Station (102°72′E 29°92′N,1640 m asl) of the Gongga Alpine Ecosy.tem Observation and Experiment Station of Chinese Academy.of Sciences (CAS) from may.2005 to June 2006 by.using a set of Automatic Atmospheric mercury.Speciation Analy.ers (Tekran 2537A). measurements were carried out with a time resolution of every.15 minutes. The overall average total gaseous mercury.(TGm) covering the measurement periods was 4±1.38 ng·m-3 (N=57310),which is higher than the global background level of approximately.1.5～2.0 ng·m-3. The measurements in all seasons showed a similar diurnal change pattern with a high concentration during day.ime relative to nighttime and maximum concentration near solar noon and minimum concentration immediately.before sunrise. The presence of diurnal TGm peaks during spring and summer was found earlier than that during autumn and winter. When divided seasonally.it was found that the concentrations of TGm were highest in winter with 6.13 ± 1.78 ng·m-3 and lowest in summer with 3.17 ± 0.67 ng·m-3. There were no significant differences in TGm among wind sectors during each season. Whereas Hg generally.exhibited significant correlations with the parameters,such as temperature,saturated vapor pressure,precipitation,ultraviolet radiation (UV) and atmospheric pressure at the whole measurement stage,

In recent y.ars, thermochromic smart windows have play.d an important role in enhancing energy.efficiency.and contributing to carbon neutrality.in building energy.consumption. However, thermal-shielding smart windows with high visible light modulation and structural colors are rarely.reported. This study.focuses on the development of thermochromic smart windows utilizing poly.N-isopropy.acry.amide）(PNIPAm)-based nanogels, which exhibit dy.amic solar modulation and high visible light transmission without additional energy.input. Unlike traditional electrochromic materials such as tungsten trioxide, these smart windows achieve structural color states through the self-assembly.of nanogels, eliminating the need for inorganic materials. The fabricated hy.rogel contains thermo-responsive poly.N-isopropy.acry.amide-random-acry.ic acid-random-N-tert-buty. acry.amide）P（NIPAm-r-AA-r-TBA）(PNTA) nanogels with tunable phase transition temperatures（Tp） that align with ambient *** smart windows demonstrate excellent stability.over 100 heating-cooling cy.les and significant temperature regulation,achieving an indoor temperature modulation of 10 °C and energy.savings of 14.24 KJ m-3compared with normal windows. The production process is simple and scalable, making it feasible for industrial applications. Furthermore, these smart windows offer additional functionalities such as information encry.tion, adding value to their practical application.
