Effect of Temperature and Mole Ratio on the Synthesis Yield of Rhenium-Tetrofosmin

open access: yesAtom Indonesia, 2015
Technetium-99m (99mTc) tetrofosmin is widely used in nuclear medicine as a diagnostic agent for myocardial perfusion and as a tumor imaging agent. As a parenteral preparation it requires an evaluation of its pharmacokinetics and stability in-vivo.

A Review of the Impact of Radiation Damage on the Mechanical Properties of Borosilicate Glasses

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 6, November 2026.
Under irradiation, borosilicate glasses are modified at the atomic scale, including the formation of undercoordinated ions, that lead to changes in macroscopic properties. Decades of research have illuminated many aspects of the effects of radiation damage, but the complexity of these glasses leaves several unanswered questions.

Spot size reduction and minibeam creation in a proton PBS nozzle using multipole permanent magnets

open access: yesMedical Physics, Volume 53, Issue 11, November 2026.
Abstract Background Smaller spot sizes in pencil beam scanning (PBS) nozzles are generally desired to allow more conformal treatments and to spare normal tissue and organs at risk. The production of small diameter proton beams, especially proton minibeams, is challenging because long drift spaces in standard PBS nozzles exacerbate effects of MCS and ...

Quantifying photon counting detector (PCD) performance using PCD‐CT images. Part II. detector spectral response function of clinical scanners

open access: yesMedical Physics, Volume 53, Issue 11, November 2026.
Abstract Background An earlier publication, Med. Phys. 52:2796 (2025), reported a method for estimating the mean output counts of photon‐counting detectors (PCDs) from reconstructed PCD‐CT images. This capability provides a foundation for end users of clinical PCD‐CT systems to characterize PCD performance without access to raw data.

Farnesyltransferase Enables Modular Assembly of Dual‐Functional Nanobody Conjugates for in Vivo Imaging of Inflammation

open access: yesAngewandte Chemie, Volume 138, Issue 42, 12 October 2026.
A modular farnesyltransferase‐based chemoenzymatic platform enables fast, site‐specific labeling of nanobodies for PET imaging of inflammation. CD11b‐targeted PET agents selectively image myeloid‐driven inflammation, while CD45‐targeted PET agents provide sensitive whole‐body immune mapping.

Updated Estimates of Radiocarbon‐Based Deep Ocean Circulation Age

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract The deep ocean circulation age based on radiocarbon was last determined almost 20 years ago, when digital archiving was not standard practice. This work updates the circulation age while making two improvements by using new nutrient data and modifying the calculation. The newly calculated circulation age is spatially more coherent and older in

Fasting serum annexin A2 is associated with peripheral insulin sensitivity and may enhance glucose uptake via Src‐dependent signaling

open access: yesJournal of Diabetes Investigation, Volume 17, Issue 11, Page 2034-2043, November 2026.
Circulating Annexin A2 is positively associated with peripheral insulin sensitivity. ABSTRACT Background and Aim Subcellular annexin A2 (ANXA2) is known to regulate membrane dynamics and GLUT4 trafficking in adipocytes; however, the role of serum ANXA2 in glucose metabolism remains unclear.

Spleens With Disseminated Lymphoma Exhibit Higher Standardized Uptake Value Maximum, Metabolic Tumor Volumes, and Total Lesion Glycolysis on Fluorine‐18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography

open access: yesVeterinary Radiology &Ultrasound, Volume 67, Issue 6, November 2026.
ABSTRACT Standardized uptake value maximum (SUVmax), metabolic tumor volumes (MTV), and total lesion glycolysis (TLG) are metabolic parameters used to quantify tumors detected on fluorine‐18 fluorodeoxyglucose positron emission tomography/computed tomography (18F‐FDG PET/CT).
