To the Editor:Actinic keratosis(AK)is a precancerous skin condition caused by chronic exposure to ultraviolet *** mainly occurs on sun-exposed areas like the head and face,leading to cosmetic concerns and an increased risk of progressing to primary squamous cell carcinoma(with a 0.60%risk at 1 year and 2.57%risk at 4 years).[1]Photodynamic therapy(PDT)is a targeted,non-invasive therapy that has been approved in Europe for the treatment of AK,squamous cell carcinoma in situ,and basal cell carcinomas.5-Aminolaevulinic acid(ALA)-based PDT,which utilizes the photosensitizer ALA,has shown high cure rates,low recurrence rates,and favorable cosmetic outcomes as arst-line treatment for AK.[1]However,due to variations in skin color,ethnicity,and lifestyle habits,the incidence of AK is lower among Asians compared to Caucasians.[1]There are limited clinical studies on PDT for AK in Asia—particularly lacking large-scale multicenter *** knowledge gap hinders the establishment of treatment standards specically tailored for Asian patients with AK undergoing ***,as the aging population increases in Asia,the incidence of AK demand for medical intervention among Asians is also rising *** conducted this multicenter study aiming to comprehensively investigate the efcacy and safety of ALA-PDT in Chinese patients with AK.

Spectral observation of symmetry-protected selection rules for dynamical high-dimensional parity in alignment magnetic resonance

Science China(Physics,Mechanics & Astronomy) 2024年第10期Mechanics & Astronomy) .卷 5-15页

Multidimensional Floquet-driven alignment systems with dynamical symmetry present various exotic phenomena and applications. However, there are challenges in directly characterizing large-spin dynamical symmetry from spectra. Here, we first observe the symmetry-protected selection rules of dynamical high-dimensional parity in a large-spin(F = 4) system. We theoretically construct a Floquet-driven alignment system that can be used to reveal high-dimensional spatiotemporal symmetry. In the experiment, the system is implemented in Cs atomic gas subjected to two-dimensional Floquet-modulated magnetic resonance driving. By developing Floquet detection protocols of alignment double-sided spectra, we directly verify symmetry-protected selection rules of dynamical high-dimensional parity for large-spin systems. This work advances the exploration of dynamical symmetry to large spins, and unravels a universal Floquet scheme for the investigation of symmetry-protected selection rules.

The overall photocatalytic CO_(2) reduction reaction(OPCRR)that can directly convert CO_(2) and H_(2)O into fuels represents a promising renewable energy conversion *** a typical redox reaction,the OPCRR involves two half-reactions:the CO_(2) reduction half-reaction(CRHR)and the water oxidation half-reaction(WOHR).Generally,both half-reactions can be promoted by adjusting the wettability of ***,there is a contradiction in wettability requirements for the two ***,CRHR prefers a hydrophobic surface that can accumulate more CO_(2) molecules on the active sites,ensuring the appropriate ratio of gas-phase(CO_(2))to liquid-phase(H_(2)O)***,the WOHR prefers a hydrophilic surface that can promote the departure of the gaseous product(O_(2))from the catalyst surface,preventing isolation between active sites and the reactant(H_(2)O).Here,we successfully reconciled the contradictory wettability requirements for the CRHR and WOHR by creating an alternately hydrophobic *** was achieved through a selectively hydrophobic modification method and a charge-transfer-control ***,the collaboratively promoted CRHR and WOHR led to a significantly enhanced OPCRR with a solar-to-fuel conversion efficiency of 0.186%.Notably,in ethanol production,the catalyst exhibited a 10.64-fold increase in generation rate(271.44μmol g^(-1)h~(-1))and a 4-fold increase in selectivity(55.77%)compared to the benchmark *** innovative approach holds great potential for application in universal overall reactions involving gas participation.

Podostemaceae(riverweed family),one of the largest aquatic plant families in the world,comprises about 350 species in 51 genera placed in three subfamilies,Podostemoideae,Weddellinoideae,and Tristichoideae(Koi et al.,2022).Most Podostemaceae genera(~38)are monotypic or oligotypic,with a high level of endemism(Koi et al.,2018,2022).Members of Podostemaceae adhere to rocks in fast-flowing rivers,streams,or waterfalls in the subtropics and tropics(Koi et al.,2018).As an adaptation to fastrunning currents,the morphological structure of river-weeds tends to be extremely reduced,including a loss or reduction of primary shoots or roots(Koi and Kato,2007).The vegetative mass of these plants resembles lichens or bryophytes,and are thus known commonly as“dream bryophytes”(Philbrick and Retana,1998).Podostemaceae plants flower when the water level drops during the dry *** recent years,anthropogenic factors and climate change have severely affected river weed habitats,decreasing populations of these plants.
