Establishment of MS LOC platform and its pilot application in clinical lipidomics.

Lipidomics has demonstrated significant potential for disease diagnosis and prediction. The development and optimization of a robust mass spectrometry (MS) platform for lipidome analysis is critically important, as it can facilitate biomarker discovery, cohort testing, and performance evaluation in clinical lipidomics studies. In this work, we developed a high-throughput and reliable platform, termed MS Lab on a Chip (MS LOC), which integrates the MetArray chip, an automated lipidomics pretreatment protocol, and the reflectron matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) instrument.

Prevalence of antiphospholipid antibodies in COVID-19 patients: A meta-analysis.

Objective: In some reports, antiphospholipid antibodies (aPL) prevalence is higher in COVID-19 patients. This study intended to compare aPL prevalence between COVID-19 patients and healthy controls, and differences in aPL types using meta-analysis.

Methods: This work retrieved published literature about association between COVID-19 and aPL from Embase, Web of Science, PubMed, and The Cochrane Library databases.

Causal relationship between neuroticism and frailty: A bidirectional Mendelian randomization study.

Background: Observational studies have shown that neuroticism is associated with frailty, but the causal relationship between them remains unclear.

Methods: A two-sample Mendelian randomization (MR) study was conducted to explore the bidirectional causal relationship between neuroticism (n = 380,506 for the primary analysis, n = 79,004 for the validation) and frailty (n = 175,226) using publicly available genome-wide association study data. The inverse variance weighted (IVW), weighted median, and MR-Egger were used to obtain the causal estimates.

Overexpression of KIAA0101 Promotes the Progression of Non-small Cell Lung Cancer.

Lung cancer is the leading cause of cancer related death worldwide, with a continue-rising incidence. The proliferating cell nuclear antigen binding protein KIAA0101 is highly expressed in various types of cancer, including non-small cell lung cancer (NSCLC). However, its biological role and underlying mechanisms in NSCLC remains unclear.

Female genital tract metastasis of lung adenocarcinoma with EGFR mutations: Report of two cases.

Background: The female genital tract is an uncommon site of involvement for extra-genital malignancies. Ovarian metastases have been described as disseminations of lung adenocarcinoma; rare cases of secondary localizations in the cervix, adnexa, and vagina have also been reported in the literature. Here, we report two cases of advanced lung adenocarcinoma with female genital tract metastasis.
