Iodinated contrast media (iodinated CM) have increased ability to absorb x-rays and to visualize structures that normally are impossible to observe in a radiological examination. The use of iodinated CM may destory renal function, commonly known as contrast-induced nephropathy (CIN), which can result in acute renal failure (ARF). This review article mainly focuses on the following areas: (1) classifications of iodinated CM: ionic or non-ionic, high-osmolarity contrast media (HOCM), low-osmolarity contrast media (LOCM) and iso-osmolarity contrast media (IOCM); (2) an introduction to the physical and chemical properties of the non-ionic iodinated CM; (3) the management of anaphylactic reaction by iodinated CM; (4) a suggested single injection of adult doses and maximum dose for non-ionic iodinated CM; (5) the molecular mechanism of contrast-induced nephropathy (CIN); (6) In vitro studies on iodinated CM. Based on above information, this review article provide an insight for understanding the drug safety of iodinated CM.

Developing artificial hosts with temperature-driven conformational switching behaviors facilitates our understanding of the temperature-dependent allostery and adaptation mechanisms in natural recognition systems. Herein, we report the design and synthesis of three pairs of water-soluble, enantiomeric binaphthalene-based tetraimidazolium macrocycles (SS/RR-1•4Cl- - SS/RR-3•4Cl-) as artificial hosts for exploring sequence-selective recognition of dinucleotides in aqueous media. Owing to the reversible rotational conformation of axially chiral binaphthyl units, SS-1•4Cl- demonstrates the conformational switching, converting from cis-conformation (SS-1) to trans-conformation (SS-1) by increasing temperature, thereby causing the recognition cavity to transition from a closed to an open state.

Salmonella Typhimurium (S. Typhimurium) is one of the most common food-borne diseases, highlighted as the top food-borne bacterial pathogen in the world with a low infectious dose (1 CFU) and high mortality rate. It is commonly associated with numerous foods such as dairy products, protein sources (multiple types of meat, poultry, and eggs), and bakery products.

Background: Contrast-induced acute kidney injury (CIAKI) is the third cause of hospital-acquired acute kidney injury and diabetes mellitus (DM) was identified as a risk factor for CIAKI. However, the molecular mechanism underlying DM-CIAKI remains unclear, which needs further investigation.
Methods: DM-CIAKI models of mice and cells were established.

Prostate cancer represents the second most prevalent malignancy among males globally, exhibiting a significantly lower 5-year survival rate in China relative to Western nations. Early diagnosis constitutes a critical factor in enhancing clinical outcomes. Ultrasound molecular imaging has emerged as a non-invasive and widely accessible diagnostic modality.

Patients with inflammation-associated coronary artery disease (CAD) may exhibit rapid progression and require regular coronary imaging. To evaluate the diagnostic performance of spectral photon-counting detector (PCD) coronary CTA with reduced radiation and contrast media doses for detecting coronary stenosis and in-stent restenosis in patients with inflammation-associated CAD. This prospective study enrolled patients with inflammation-associated CAD from January 2023 to March 2024.
