AI Article Synopsis
- The US Nuclear Regulatory Commission (NRC) and 38 Agreement States regulate the use of radioisotopes in medicine, focusing on training and experience requirements for users outlined in 10CFR35.390.
- The NRC is currently reviewing major revisions to these training and experience regulations.
- The article discusses the existing regulations, concerns regarding the proposed changes, and the response from the American College of Radiology (ACR).
Article Abstract
The US Nuclear Regulatory Commission (NRC) and 38 Agreement States have the regulatory authority to promulgate and enforce regulations related to the use of radioisotopes for medical purposes. Elements of these regulations include training and experience (T&E) requirements for individuals authorized to use the agents. These regulations are specified in 10CFR35.390. At this time, the NRC is considering significant revisions to the T&E requirements. This article describes current regulations and concerns related to the proposed changes and details the ACR organizational response.

The Cas12j-8 nuclease, derived from the type V CRISPR system, is approximately half the size of Cas9 and recognizes a 5'-TTN-3' protospacer adjacent motif sequence, thus potentially having broad application in genome editing for crop improvement. However, its editing efficiency remains low in plants. In this study, we rationally engineered both the crRNA and the Cas12j-8 nuclease.

Backgrounds And Aims: CD8+T cells are crucially associated with the fight against hepatitis B virus (HBV) infection. CD161 has been shown to express remarkably on HCV-specific CD8+T cells. However, the accurate function of CD161+CD8+T cells in HBV immunity or pathogenesis remains undetermined.

Angiogenesis begins as endothelial cells migrate, forming a sprouting tip and subsequent growth-rich stalk cells. Here, we present a protocol for transcriptomic and epigenomic analyses of tip-like cells in cultured endothelial cells. We describe steps for stimulating human umbilical vein endothelial cells (HUVECs) with vascular endothelial cell growth factor (VEGF) to generate tip-like cells.

Interleukin (IL)-7 promotes T cell expansion during lymphopenia. We studied the metabolic basis in CD4 T cells, observing increased glucose usage for nucleotide synthesis and oxidation in the tricarboxylic acid (TCA) cycle. Unlike other TCA metabolites, glucose-derived citrate does not accumulate upon IL-7 exposure, indicating diversion into other processes.

Early cancer detection substantially improves the rate of patient survival; however, conventional screening methods are directed at single anatomical sites and focus primarily on a limited number of cancers, such as gastric, colorectal, lung, breast, and cervical cancer. Additionally, several cancers are inadequately screened, hindering early detection of 45.5% cases.
