The Code of Federal Regulations is a single-source repository of all rules and regulations promulgated by federal departments and agencies. In Title 10, Chapter 1, Part 35, Subpart D, §§35.100 to 35.290 detail regulations for the use of unsealed by product material not requiring a written directive (ie, diagnostic radiopharmaceuticals), and in Subpart E, §§35.300 to 35.396 detail regulations for the use of unsealed by product material requiring a written directive (ie, therapeutic radionuclides). Currently proposed changes for both Subparts D and E could have profound effects on patient care, public safety, and the practice of nuclear medicine, diagnostic radiology, and radiation oncology. This article details those proposed changes and actions under way to prevent promulgation of proposals that could negatively affect patient care and public safety.

Genesis and regulation of C-terminal cyclic imides from protein damage.
Proc Natl Acad Sci U S A
January 2025
Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138.
C-Terminal cyclic imides are posttranslational modifications that can arise from spontaneous intramolecular cleavage of asparagine or glutamine residues resulting in a form of irreversible protein damage. These protein damage events are recognized and removed by the E3 ligase substrate adapter cereblon (CRBN), indicating that these aging-related modifications may require cellular quality control mechanisms to prevent deleterious effects. However, the factors that determine protein or peptide susceptibility to C-terminal cyclic imide formation or their effect on protein stability have not been explored in detail.

NADH dehydrogenase (ubiquinone) 1 alpha subcomplex, 4-like 2 (NDUFA4L2) protein is located in the mitochondria and can regulate cell proliferation. Some studies have shown that the high NDUFA4L2 expression is linked with poor prognosis and cancer progression in various patients with cancers. However, the correlation between NDUFA4L2 and pan-cancer is unknown.

Ubiquitin-conjugating enzyme E2 T (UBE2T) is a crucial E2 enzyme in the ubiquitin-proteasome system (UPS), playing a significant role in the ubiquitination of proteins and influencing a wide range of cellular processes, including proliferation, differentiation, apoptosis, invasion, and metabolism. Its overexpression has been implicated in various malignancies, such as lung adenocarcinoma, gastric cancer, pancreatic cancer, liver cancer, and ovarian cancer, where it correlates strongly with disease progression. UBE2T facilitates tumorigenesis and malignant behaviors by mediating essential functions such as DNA repair, apoptosis, cell cycle regulation, and the activation of oncogenic signaling pathways.

Radiation Oncology, Thomas Jefferson University Hospital, Philadelphia, USA.
Purpose Low-dose total skin electron beam therapy (LD-TSEBT) has recently gained popularity in treating mycosis fungoides (MF) due to its reduced toxicity and favorable response rates. Combining accelerated LD-TSEBT with the modified Stanford technique (mST), a condensed cycling approach, offers a promising and convenient option. However, in vivo dosimetry data confirming the effectiveness of this approach is limited.

The HKT-type proteins have been extensively studied and have been shown to play important roles in long-distance Na transport, maintaining ion homoeostasis and improving salt tolerance in plants. However, there have been no reports on the types, characteristics and functions of HKT-type proteins in Limonium bicolor, a recretohalophyte species with the typical salt gland structure. In this study, five LbHKT genes were identified in L.
