Metastatic cancer cells undergo metabolic reprogramming, which involves changes in the metabolic fluxes, including endocytosis, nucleocytoplasmic transport, and mitochondrial metabolism, to satisfy their massive demands for energy, cell division, and proliferation compared to normal cells. We have previously demonstrated the ability of two different types of compounds to interfere with linchpins of metabolic reprogramming, Pitstop-2 and 1,6-hexanediol (1,6-HD). 1,6-HD disrupts glycolysis enzymes and mitochondrial function, enhancing reactive oxygen species production and reducing cellular ATP levels, while Pitstop-2 impedes clathrin-mediated endocytosis and small GTPases activity.

The duration of mechanical systole-also termed the flow time (FT) or left ventricular ejection time (LVET)-is measured by Doppler ultrasound and increasingly used as a stroke volume (SV) surrogate to guide patient care. Nevertheless, confusion exists as to the determinants of FT and a critical evaluation of this measure is needed. Using Doppler ultrasound of the left ventricular outflow tract velocity time integral (LVOT VTI) as well as strain and strain rate echocardiography as grounding principles, this brief commentary offers a model for the independent influences of FT.

Levy Place, New York, NY 10029 (Y.Z., D.F.Y., C.I.H.); and Department of Radiology, The First Affiliated Hospital of Guangzhou Medical University, Guangzhou, China (Y.Z.).
Lung cancer is the leading cause of cancer deaths globally. In various trials, the ability of low-dose CT screening to diagnose early lung cancers leads to high cure rates. It is widely accepted that the potential benefits of low-dose CT screening for lung cancer outweigh the harms.

Objective: Although studies have examined changes in C-reactive protein (CRP) during pulmonary exacerbations (PEX) in people with cystic fibrosis (PwCF), few have evaluated CRP profiles across age groups. Here, we characterize age-related CRP responses to PEX treatment.
Methods: We measured CRP concentrations at the beginning and end of intravenous (IV) antibiotic therapy for PEX in 100 pediatric and 147 adult PwCF at 10 US CF Centers.
Protective Effects of Monoacylglycerol Lipase Inhibition in Rats with Severe Acute Pancreatitis and Its Possible Mechanism.
Endocr Metab Immune Disord Drug Targets

Department of Gastroenterology, Shandong Provincial Hospital Affiliated to Shandong First Medical University, 324 Jingwu Weiqi Rd, Jinan, 250021, China.
Background And Aim: In the context of gastrointestinal diseases, the role of monoacylglycerol lipase (MAGL) is significant. Therefore, the objective of this study was to examine the protective effects of MAGL inhibition using JZL184 in rat models of severe acute pancreatitis (SAP) and to explore its mechanism.
Methods: In this study, a rat model of SAP was established, and the rats were divided into three groups for treatment: the Control group (CON), the SAP group (SAP), and the SAP group treated with JZL184 (JZL184).
