Impact of organic pollutants on phenotype and gene expression in human breast cancer cells

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Human exposure to industrial chemical compounds is widespread and, although often beneficial, prolonged contact may contribute to disease development, including cancer. While many studies have shown organic pollutants (OP) are cytotoxic, few have explored how long‐term exposure alters cell phenotype.

Non‐Subtractive Arterial Spin Labeling‐Based (NSASL) Renal Magnetic Resonance Angiography (MRA): Development and Clinical Feasibility Evaluation

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Non‐contrast renal MR angiography (MRA) is valuable for patients who cannot receive contrast agents or when avoiding radiation is desired. However, the conventional inflow inversion recovery (IFIR) method is limited by incomplete background suppression, venous contamination, and motion sensitivity.

Lower Plasma Antioxidant Defense and Heat Shock Proteins Mark Intra‐Amniotic Sludge Ultrasound Finding

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives Intra‐amniotic sludge is an independent risk factor for preterm birth. It consists of a biophysical sonographic finding in the amniotic fluid, formed by dense echogenic particles near the cervical internal orifice, due to sterile or infectious inflammatory processes.

An autonomous and economical benthic incubation chamber for measuring dissolved oxygen fluxes in shallow, low‐flow environments

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Benthic incubation chambers enclose a known volume of water overlying a known area to measure water chemistry changes and are typically used to quantify the metabolic activity of benthic organisms or communities. Here we present an economical benthic incubation chamber for shallow, low‐flow environments, built using off‐the‐shelf components ...
