Environmental Toxicology and Chemistry, EarlyView.Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

A Critical Overview of Common Foodborne Toxicants and Methods for Their Reliable Detection
Food Frontiers, EarlyView.ABSTRACT Food is an essential commodity for human health. However, toxicants such as mycotoxins, heavy metals, acrylamide, and pesticides can be present in food either naturally or through processing, packaging, or some anthropogenic activities. A thorough review of carefully selected studies revealed that climate change and pandemics have led to an ...

What Does Iron Mean to an Oligodendrocyte?
Glia, EarlyView.ABSTRACT Iron is essential for life and plays a key role in multiple fundamental cellular functions. The brain has the highest rate of energy consumption, and within the brain, oligodendrocytes have the highest level of oxidative metabolism per volume. Oligodendrocytes also stain the strongest for iron.

Use of progress curves to estimate the co-substrate-to-substrate flow ratio of a symport mechanism. Application to the isoleucine-Na+ symport of mouse ascites-tumour cells and to the lactose-proton symport [PDF]
Biochemical Journal, 1988 The model envisages two components in the process, whereby Ht equivalents of co-substrate and St equivalents of substrate accumulate in the cellular compartment in time t. The first is the flow through the symport, n equivalents of co-substrate entering or leaving with each substrate equivalent.

Conformational Space and Dynamics of Sodium-Coupled Symporters [PDF]
Biophysical Journal, 2011 Secondary transporters utilize the free energy stored in the sodium gradient to move a solute against a concentration gradient. The transport process involves a sequence of conformational changes that exposes the substrate and ion binding sites alternatively to the extracellular and the intracellular compartment.

ChemistryOpen, EarlyView.A method to detect perchlorate ions and certify safe drinking water by constructing a fluorescence‐based logic gate considering the binding of a hemicyanine dye with β‐CD is presented. Perchlorate ions (ClO4−) are prevalent contaminants in the surface, and drinking water that disrupt thyroid function by competitively inhibiting the sodium‐iodide ...

Sodium-Sulfate Symport by Aplysia californica Gut [PDF]
Zoological Science, 2000 Sulfate transport across plasma membranes has been described in a wide variety of organisms and cell types including gastrointestinal epithelia. Sulfate transport can be coupled to proton, sodium symport or antiport processes involving chloride or bicarbonate. It had previously been observed in Aplysia gut that sulfate was actively absorbed.

Cancer Science, EarlyView.Our study reveals that hypoxia inhibitors ameliorate iodine uptake dysfunction in thyroid cancer by acting on the hsa_circ_0023990/miR‐448/DNMT1/NIS signaling pathway. ABSTRACT This research seeks to investigate how hypoxia inhibitors enhance iodine uptake in thyroid cancer cells. Clinical samples were gathered and assessed for hsa_circ_0023990, DNMT1,

A mechanism for intracellular release of Na+ by neurotransmitter/sodium symporters [PDF]
Nature Structural & Molecular Biology, 2014 Neurotransmitter/sodium symporters (NSSs) terminate synaptic signal transmission by Na+-dependent reuptake of released neurotransmitters. Key conformational states have been reported for the bacterial homolog LeuT and an inhibitor-bound Drosophila dopamine transporter. However, a coherent mechanism of Na+-driven transport has not been described.
