DataSheet2_Current Research Progress of the Role of LncRNA LEF1-AS1 in a Variety of Tumors.docx
Long non-coding RNAs (lncRNA), as key regulators of cell proliferation and death, are involved in the regulation of various processes in the nucleus and cytoplasm, involving biological developmental processes in the fields of immunology, neurobiology, cancer, and stress. There is great scientific interest in exploring the relationship between lncRNA and tumors. Many researches revealed that lymph enhancer-binding factor 1-antisense RNA 1 (LEF1-AS1), a recently discovered lncRNA, is downregulated in myeloid malignancy, acting mainly as a tumor suppressor, while it is highly expressed and carcinogenic in glioblastoma (GBM), lung cancer, hepatocellular carcinoma (HCC), osteosarcoma, colorectal cancer (CRC), oral squamous cell carcinoma (OSCC), prostatic carcinoma, retinoblastoma, and other malignant tumors. Furthermore, abnormal LEF1-AS1 expression was associated with tumorigenesis, development, survival, and prognosis via the regulation of target genes and signaling pathways. This review summarizes the existing data on the expression, functions, underlying mechanism, relevant signaling pathways, and clinical significance of LEF1-AS1 in cancer. It is concluded that LEF1-AS1 can serve as a novel biomarker for the diagnosis and prognosis of various tumors, thus deserves further attention in the future.</p

Image1_A Prognostic Model of Pancreatic Cancer Based on Ferroptosis-Related Genes to Determine Its Immune Landscape and Underlying Mechanisms.TIF
Pancreatic cancer is one of the malignant tumors with the worst prognosis in the world. As a new way of programmed cell death, ferroptosis has been proven to have potential in tumor therapy. In this study, we used the TCGA-PAAD cohort combined with the previously reported 60 ferroptosis-related genes to construct and validate the prognosis model and in-depth analysis of the differences in the function and immune characteristics of different RiskTypes. The results showed that the six-gene signature prognostic model that we constructed has good stability and effectiveness. Further analysis showed that the upregulated genes in the high-risk group were mainly enriched in extracellular matrix receptor-related pathways and other tumor-related pathways and the infiltration of immune cells, such as B, T, and NK cells, was suppressed. In short, our model shows good stability and effectiveness. Further studies have found that the prognostic differences between different RiskTypes may be due to the changes in the ECM-receptor pathway and activation of the immune system. Additionally, ICI drugs can treat pancreatic cancer in high-risk groups.</p
<i>In Situ</i> Characterization of Mixtures of Linear and Branched Hydrocarbons Confined within Porous Media Using 2D DQF-COSY NMR Spectroscopy
The analysis of 1D anti-diagonal
spectra from the projections of
2D double-quantum filtered correlation spectroscopy NMR spectra is
presented for the determination of the compositions of liquid mixtures
of linear and branched alkanes confined within porous media. These
projected spectra do not include the effects of line broadening and
therefore retain high-resolution information even in the presence
of inhomogeneous magnetic fields as are commonly found in porous media.
A partial least-square regression analysis is used to characterize
the mixture compositions. Two case studies are considered. First,
mixtures of 2-methyl alkanes and n-alkanes are investigated.
It is shown that estimation of the mol % of branched species present
was achieved with a root-mean-square error of prediction (RMSEP) of
1.4 mol %. Second, the quantification of multicomponent mixtures consisting
of linear alkanes and 2-, 3-, and 4-monomethyl alkanes was considered.
Discrimination of 2-methyl and linear alkanes from other branched
isomers in the mixture was achieved, although discrimination between
3- and 4- monomethyl alkanes was not possible. Compositions of the
linear alkane, 2-methyl alkane, and the total composition of 3- and
4-methyl alkanes were estimated with a RMSEP <3 mol %. The approach
was then used to estimate the composition of the mixtures in terms
of submolecular groups of CH3CH2, (CH3)2CH, and CH2CH(CH3)CH2 present in the mixtures; a RMSEP <1 mol % was achieved for all
groups. The ability to characterize the mixture compositions in terms
of molecular subgroups allows the application of the method to characterize
mixtures containing multimethyl alkanes. The motivation for this work
is to develop a method for determining the mixture composition inside
the catalyst pores during Fischer–Tropsch synthesis. However,
the method reported is generic and can be applied to any system in
which there is a need to characterize mixture compositions of linear
and branched alkanes

Image_1_Different uptake patterns of 68Ga-FAPI in aseptic loosening and periprosthetic joint infection of hip arthroplasty: A case series and literature review.JPEG
BackgroundThe diagnosis of a periprosthetic joint infection (PJI) is always a difficult point in research on the surgery of joints. The current diagnostic criteria include a comprehensive analysis of multiple tests; however, there are no effective visual examinations yet that can differentiate between aseptic loosening and the PJI.Case presentationThis case report describes four patients with symptomatic total hip arthroplasty (THA), two cases of loosening and two cases of infection. Although the four cases were correctly diagnosed by the tissue culture, preoperative tests and pathological examination could not effectively distinguish an infection from a non-infection. Based on a preclinical study and theoretical feasibility, gallium-68 (68Ga)-labeled fibroblast activation protein inhibitor positron emission tomography/computed tomography (68Ga-FAPI PET/CT) was performed. Through 68Ga-FAPI PET/CT scanning, not only were the causes diagnosed correctly but the lesions were also located.ConclusionWhen the lesion is located between the bone and the prosthesis, 68Ga-FAPI PET/CT could differentiate aseptic loosening from periprosthetic joint infection (PJI). 68Ga-FAPI PET/CT has clear advantages over routine examinations and has a prospective application in detecting PJI.</p
