The value of F-fluorodeoxyglucose positron emission tomography-based radiomics in non-small cell lung cancer.

Currently, the second most commonly diagnosed cancer in the world is lung cancer, and 85% of cases are non-small cell lung cancer (NSCLC). With growing knowledge of oncogene drivers and cancer immunology, several novel therapeutics have emerged to improve the prognostic outcomes of NSCLC. However, treatment outcomes remain diverse, and an accurate tool to achieve precision medicine is an unmet need.

A simple, economical, and high-yield method for polyethylene glycol-based extraction of follicular and serum-derived extracellular vesicles.

Objectives: The optimization of polyethylene glycol (PEG)-based extracellular vesicles (EVs) extraction from human follicular fluid (FF) and serum was investigated, and their functional analysis was confirmed. The PEG-based EV results were compared to the ExoQuick (ExoQ)-based EV.

Materials And Methods: FF-EVs and serum-EVs were extracted by using different concentrations of PEG (8000).

Associations Between Prenatal Dioxin-like Polychlorinated Biphenyls Exposure and Glucocorticoid and Androgenic Hormones in Umbilical Cord Blood.

This study investigates the association between prenatal exposure to dioxin-like polychlorinated biphenyls (DL-PCBs) and glucocorticoid and androgenic hormone levels in cord blood. We analyzed cord blood samples from 500 mother-infant pairs from China (2022-2023), focusing on hormones including cortisol, cortisone, dehydroepiandrosterone (DHEA), and androstenedione. The main analysis revealed significant reductions in cortisol levels with increased exposure to PCB-77 (β = -3.

Gadopiclenol Enables Reduced Gadolinium Dose While Maintaining Quality of Pulmonary Arterial Enhancement for Pulmonary MRA: An Opportunity for Improved Safety and Sustainability.

Rationale And Objectives: Pulmonary magnetic resonance angiography (MRA) is an imaging method with proven utility for the exclusion of pulmonary embolism and avoids the need for ionizing radiation and iodinated contrast agents. High-relaxivity gadolinium-based contrast agents (GBCAs), such as gadopiclenol, can be used to reduce the required gadolinium dose for pulmonary MRA. The aim of this study was to compare the contrast enhancement performance of gadopiclenol with an established gadobenate dimeglumine-enhanced pulmonary MRA protocol.

Dementia and epilepsy without traumatic brain injury among subjects middle-aged females: a population-based case-control study.

Although the association between dementia such as Alzheimer's disease and traumatic brain injury (TBI) is well established, there are significant knowledge gaps with respect to the perspective of dementia and epilepsy without TBI. We aimed to investigate the relationship between dementia and epilepsy in a population-based study of patients without history of TBI. This study included a random sample of 30,715 patients with no history of TBI, including 6143 with epilepsy as the study cohort and 24,572 without epilepsy as the comparison cohort.
