Dear Editor,The choice of surgical intervention for nanophthalmos patients with secondary angle-closure glaucoma poses a challenging decision for *** nanophthalmos patients who have undergone filtration surgery or other intraocular procedures are more susceptible to severe complications,including choroidal effusion,malignant glaucoma,and explosive choroidal hemorrhage,all of which can lead to vision loss[1..This dilemma is particularly pronounced in patients with shorter axial *** transscleral laser therapy(M-TLT),also known as micropulse transscleral cyclophotocoagulation(MP-TSCPC),is a nonincisional laser therapy surgery for glaucoma[2].In 201.,Golan and Kurtz[3]were the first to report four patients with secondary angle-closure glaucoma in nanophthalmos with axial lengths ranging between 1. and 1. mm(mean 1. mm)who were successfully treated with M-TLT,and choroidal detachment was observed in all patients(recovery spontaneously in two patients and recovery after systemic steroid treatment in the other two),of which two had a slight decrease in visual acuity.

The practical energy density of lithium-sulfur batteries(LSBs)is seriously limited by the high electrolyte-to-sulfur ratios(E/S).The E/S can be reduced by employing hosts with easy-to-infiltrate structure that ensures the uniform distribution of a lean electrolyte and high catalytic activity that can suppress"shuttle effect"via accelerating the slow conversion of soluble poly sulfides to insoluble *** the easy-to-infiltrate structures,the three-dimensional-ordered macroporous(3DOM)structure is easier to scale preparation and more suitable for the existing industrial ***,it is difficult to obtain the 3DOM with(1.high penetrability due to the high viscosity of frequently-used organic polymer precursors and(2)high catalytic activity due to the low confinement effect,meaning that uniformly dispersed small-sized catalytic materials are difficult to load on ***,using carbon dots(CDs)with both organic and inorganic properties as a precursor and aggregation limiting agent,a 3DOM host with high penetrability and homodispersed Ni particles of small sizes(Ni-CDs-3DOM)was *** this host:(1.CDs precursor with suitable viscosity can improve the penetrability.(2)CDs can effectively inhibit the agglomeration of Ni particles.(3)Uniformly dispersed small-size Ni particles offer high-efficiency catalytic activity toward sulfur ***,the Ni-CDs-3DOM/sulfur cathode exhibits high sulfur utilization and stable cycling performance even under high sulfur loading(5.5 mg·cm^(-2))and low E/S(6.5μl·mg^(-1.).This work indicates the usefulness of CDs in constructing hosts for LSBs with high energy density.

Wearable triboelectric nanogenerators （TENGs） have attracted attention owing to their ability to harvest energy from the surrounding environment without maintenance. Herein, polyetherimide–Al2O3（PAl） and polyvinylidene fluoride-co-hexafluoropropylene （PVDF-HFP, PH） nanofiber membranes were used as tribo-positive and tribo-negative materials, respectively. Phytic aciddoped polyaniline （PANI）/cotton fabric （PPCF） and ethylenediamine （EDA）-crosslinked PAl （EPAl） nanofiber membranes were used as triboelectrode and triboencapsulation materials, respectively. The result showed that when the PAl–PH-based TENG was shaped as a circle with a radius of 1.cm, under the pressure of 50 N, and the frequency of 0.5 Hz, the open-circuit voltage (Voc)and short-circuit current (Isc) reached the highest value of 66.6 V and-93.4to 1.0.1.nA, respectively. Moreover, the PH-based TENG could be used as a fabric sensor to detect fabric composition and as a sensor-inductive switch for light bulbs or beeping warning devices. When the PAl–PH-based TENG was shaped as a 5×5 cm2rectangle, a 33μF capacitor could be charged to1. V in 28 s. Interestingly, compared to PAl nanofiber membranes, EPAl nanofiber membranes exhibited good dyeing properties and excellent solvent resistance. The PPCF exhibited <5%resistance change after washing,bending, and stretching.

Lung cancer(LC)is a prevalent and fatal malignancy,with high incidence and mortality rates.1.ATP binding cassette(ABC)transporters,a superfamily of integral membrane proteins,use ATP hydrolysis to facilitate substrate transport across cellular membranes.2 The pivotal role of ABC transporters in tumorigenesis was initially established by Mochida,3 who demonstrated that the loss of ABCB1.suppresses intestinal polyp formation and tumor progression in *** investigations have reported correlations between ABC transporters and the tumor microenvironment and cancer immunotherapy response,suggesting their modulatory effects on tumor progression and immunotherapy.

Open source software(OSS) projects usually employ a community-based model, where geographically distributed developers from around the world collaborate online [1..With the rise of social coding sites like Git Hub, contributing to OSS projects has become easier and more accessible, motivating many developers to join the OSS community [2]. The continued submission of high-quality contributions from these community developers has led to numerous corrections, improvements, and innovations in many successful OSS projects [1. 2].
