Table1_The construction of a prognostic model of cervical cancer based on four immune-related LncRNAs and an exploration of the correlations between the model and oxidative stress.DOCX
Introduction: The immune-related lncRNAs (IRLs) are critical for the development of cervical cancer (CC), but it is still unclear how exactly ILRs contribute to CC. In this study, we aimed to examine the relationship between IRL and CC in detail.Methods: First, the RNAseq data and clinical data of CC patients were collected from The Cancer Genome Atlas (TCGA) database, along with the immune genes from the Import database. We used univariate cox and least absolute shrinkage and selection operator (lasso) to obtain IRLs for prediction after screening the variables. According to the expression levels and risk coefficients of IRLs, the riskscore were calculated. We analyzed the relationship between the model and oxidative stress. We stratified the risk model into two as the high and low-risk groups. We also evaluated the survival differences, immune cell differences, immunotherapeutic response differences, and drug sensitivity differences between the risk groups. Finally, the genes in the model were experimentally validated.Results: Based on the above analyses, we further selected four IRLs (TFAP2A.AS1, AP000911.1, AL133215.2, and LINC02078) to construct the risk model. The model was associated with oxidative-stress-related genes, especially SOD2 and OGG1. Patients in the high-risk group had a lower overall survival than those in the low-risk group. Riskscore was positively correlated with resting mast cells, neutrophils, and CD8+ T-cells. Patients in the low-risk group showed a greater sensitivity to immunosuppression therapy. In addition, we found that patients with the PIK3CA mutation were more sensitive to chemotherapeutic agents such as dasatinib, afatinib, dinaciclib and pelitinib. The function of AL133215.2 was verified, which was consistent with previous findings, and AL133215.2 exerted a pro-tumorigenic effect. We also found that AL133215.2 was closely associated with oxidative-stress-related pathways.Discussion: The results suggested that risk modeling might be useful for prognosticating patients with CC and opening up new routes for immunotherapy.</p

Shell-Thickness-Dependent Biexciton Lifetime in Type I and Quasi-Type II CdSe@CdS Core/Shell Quantum Dots
Suppression of Auger recombination
in colloidal quantum dots (QDs)
is important for their many applications, ranging from biological
tagging, QD lasing, to solar energy conversion. Although it has been
reported that the biexciton Auger recombination time of core/shell
QDs can be significantly prolonged compared to core-only QDs, a systematic
investigation of their dependence on the shell thickness is lacking.
In this work, using CdSe@CdS core/shell QDs as a model system, we
investigated the shell thickness dependence of biexciton lifetimes
in both type I and quasi-type II QDs, prepared using large and small
core sizes, respectively. We observe a strong increase of biexciton
lifetime with the shell thickness and a larger saturation volume in
quasi-type II CdSe@CdS QDs, compared to type I CdSe@CdS QDs. These
trends can be attributed to the different thickness dependences of
electron–hole wave function overlaps in these materials, which
reflect their different extents of conduction band electron delocalization.
Our findings provide further insight for rational design of core/shell
QDs with suppressed Auger recombination rates
