A prognostic index model for assessing the prognosis of ccRCC patients by using the mRNA expression profiles of AIF1L, SERPINC1 and CES1
Background: Kidney carcinoma is a major cause of carcinoma-related
death, with the prognosis for advanced or metastatic renal cell carcinoma still
very poor. The aim of this study was to investigate feasible prognostic
biomarkers that can be used to construct a prognostic index model for clear cell
renal cell carcinoma (ccRCC) patients. Methods: The mRNA expression profiles of ccRCC samples were downloaded
from the The Cancer Genome Atlas (TCGA) dataset and the correlation of
AIF1L with malignancy, tumor stage and prognosis were evaluated.
Differentially expressed genes (DEGs) between AIF1L-low and
AIF1L-high expression groups were selected. Those with prognostic value
as determined by univariate and multivariate Cox regression analysis were then
used to construct a prognostic index model capable of predicting the outcome of
ccRCC patients. Results: The expression level of AIF1L was lower in ccRCC
samples than in normal kidney samples. AIF1L expression showed an
inverse correlation with tumor stage and a positive association with better
prognosis. ccRCC samples were divided into high- and low-expression groups
according to the median value of AIF1L expression. In the
AIF1L-high expression group, 165 up-regulated DEGs and 601
down-regulated DEGs were identified. Three genes (AIF1L,
SERPINC1 and CES1) were selected following univariate and
multivariate Cox regression analysis. The hazard ratio (HR) and 95% confidence
intervals (CI) for these genes were: AIF1L (HR = 0.83, 95% CI:
0.76–0.91), SERPINC1 (HR = 1.33, 95% CI: 1.12–1.58), and
CES1 (HR = 0.87, 95% CI: 0.78–0.97). A prognostic index model based on
the expression level of the three genes showed good performance in predicting
ccRCC patient outcome, with an area under the ROC curve (AUC) of 0.671. Conclusion: This research provides a better understanding of the
correlation between AIF1L expression and ccRCC. We propose a novel
prognostic index model comprising AIF1L, SERPINC1 and
CES1 expression that may assist physicians in determining the prognosis
of ccRCC patients

CEPC Technical Design Report -- Accelerator
The Circular Electron Positron Collider (CEPC) is a large scientific project initiated and hosted by China, fostered through extensive collaboration with international partners. The complex comprises four accelerators: a 30 GeV Linac, a 1.1 GeV Damping Ring, a Booster capable of achieving energies up to 180 GeV, and a Collider operating at varying energy modes (Z, W, H, and ttbar). The Linac and Damping Ring are situated on the surface, while the Booster and Collider are housed in a 100 km circumference underground tunnel, strategically accommodating future expansion with provisions for a Super Proton Proton Collider (SPPC). The CEPC primarily serves as a Higgs factory. In its baseline design with synchrotron radiation (SR) power of 30 MW per beam, it can achieve a luminosity of 5e34 /cm^2/s^1, resulting in an integrated luminosity of 13 /ab for two interaction points over a decade, producing 2.6 million Higgs bosons. Increasing the SR power to 50 MW per beam expands the CEPC's capability to generate 4.3 million Higgs bosons, facilitating precise measurements of Higgs coupling at sub-percent levels, exceeding the precision expected from the HL-LHC by an order of magnitude. This Technical Design Report (TDR) follows the Preliminary Conceptual Design Report (Pre-CDR, 2015) and the Conceptual Design Report (CDR, 2018), comprehensively detailing the machine's layout and performance, physical design and analysis, technical systems design, R&D and prototyping efforts, and associated civil engineering aspects. Additionally, it includes a cost estimate and a preliminary construction timeline, establishing a framework for forthcoming engineering design phase and site selection procedures. Construction is anticipated to begin around 2027-2028, pending government approval, with an estimated duration of 8 years. The commencement of experiments could potentially initiate in the mid-2030s
