Summary: In a post-mortem study, it has been found that the amyloid PET radioligand Pittsburgh compound B (PiB) interacts poorly with cotton wool plaques, which are common in familial Alzheimer's disease but rare in sporadic Alzheimer's disease. This limited interaction may lead to an underestimation of total amyloid burden in patients with familial Alzheimer's disease.

Summary: Recent advances in the diagnosis and treatment of multiple myeloma have emphasized the importance of imaging methods, particularly PET/CT, in providing accurate information for disease localization, prognosis, and therapy response evaluation. While 18F-FDG tracer is commonly used and has high sensitivity, limitations such as physiological uptake in the bone marrow and brain have prompted research on other PET tracers for improved accuracy in multiple myeloma management.

Summary: Breast cancer is a common malignant tumor that affects women globally, posing a significant threat to their health. Early detection of breast cancer can greatly improve patient prognosis and survival rates, with radionuclide molecular imaging techniques offering advantages in functional detection. Using radionuclide-labeled compounds for noninvasive visualization of biological processes helps elucidate the metabolic state of breast cancer, while receptor-targeted radionuclide molecular imaging is sensitive and specific for visualizing overexpressed molecular markers in the disease, aiding in early diagnosis and improved patient care. Rapid developments in radionuclide probes are contributing to the diagnosis of breast cancer across various aspects, with promising tools being developed for early detection.

Summary: Arterial inflammation is a significant factor in plaque vulnerability, leading to heart attacks or strokes. This study used 18F-sodium fluoride and 18F-fluorodeoxyglucose imaging to analyze arterial plaques, finding metabolically active plaques associated with inflammation even without calcification. The study suggests that density on CT images may indicate active plaques.

Summary: This study systematically appraised the methodologies used for PET imaging guidelines and compared the consistency of these recommendations. The findings showed that current guidelines for PET imaging vary in methodological quality and provided considerably inconsistent recommendations. Efforts are needed to improve adherence to guideline development methodologies, to synthesize high-quality evidence, and to adopt standard terminologies.

Summary: The lack of physically measured attenuation maps (mu-maps) in brain-dedicated stand-alone PET scanners is a challenge, but the study successfully developed a transmission-less attenuation correction method for A beta brain PET imaging using a deep learning approach. Among the three U-net models tested, the 3D U-net model showed the best performance in reducing noise and artifacts, significantly improving the accuracy of mu-map generation compared to traditional MLAA method.

Summary: Research indicates that selenium can be transported to the brain through alternative pathways independent of SELENOP, as even Selenop-knockout mice fed a diet containing adequate selenium do not exhibit neurological dysfunction observed in selenium-deficient diet-fed Selenop-knockout mice. This suggests that selenium from low-mass selenium-source compounds can be transported to the brain via alternative pathways.

Summary: Antibiotic resistance is a major threat to public health, with Gram-negative bacteria presenting unique challenges due to their low permeability and efflux pumps. Limited understanding of the chemical rules for overcoming these barriers hinders antibacterial drug discovery. Efforts to address this issue, such as screening compound libraries and using cheminformatic analysis, have led to the design of sulfamidoadenosines with diverse substituents, showing potential utility in accumulation in Escherichia coli.

Summary: This study successfully developed a short peptide mimetic as a MERS-CoV fusion inhibitor by reproducing the key recognition features of the HR2 helix. The resulting 23-mer lipopeptide showed comparable inhibitory effect to the 36-mer HR2 peptide HR2P-M2. This has important implications for developing short peptide-based antiviral agents to treat MERS-CoV infection.

Summary: Beta(2)-adrenergic receptor agonists can stimulate glucose uptake by skeletal muscle cells and are therefore potential treatments for type 2 diabetes. The chirality of compounds has a significant impact on the activity of these agonists. This study found that certain synthesized compounds showed higher glucose uptake activity. These findings provide important information for the design of novel beta(2)AR agonists for T2D treatment.
