Intra-arterial versus intra venous contrast-enhanced computed tomography of the equine head [PDF]
Background: The anatomical complexity of the horse’s head limits the abilities of radiography. Computed tomography (CT) in combination with contrast enhanced CT is used more often for diagnosing various head pathology in horses.

Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors
2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...

The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Patients at risk for contrast-induced acute kidney injury
Subjects with hypovolemia and/or dehydration and pre-existing renal failure are considered at highest risk for radiocontrast-medium-induced acute kidney injury (RCI-AKI), and this risk increases in the presence of glomerular filtration rate or creatinine

Hypothyroidism and nephrotic syndrome: why, when and how to treat [PDF]
Hypothyroidism, characterised by low/normal free thyroxine (FT4) and free tri-iodothyronine (FT3) with elevated thyroid-stimulating hormone (TSH), is a well-known complication of nephrotic syndrome (NS).

Iodinated contrast prior to evaluation for thyrotoxicosis [PDF]
AbstractBACKGROUND:Radioactive iodine is useful in the diagnosis and treatment of patients with newly diagnosed thyrotoxicosis. However, in many patients these tests are not possible to obtain due to recent administration of iodinated contrast for other types of diagnostic studies, most frequently computed tomography (CT) scans.OBJECTIVE:To determine ...
