Excitation function of (p, alpha) nuclear reaction on enriched 67Zn: Possibility of production of 64Cu at low energy cyclotron [PDF]

, 2014
The potential for production of the medically relevant 64Cu has been investigated by proton irradiation of highly enriched 67Zn targets. The excitation function of the 67Zn(p, α)64Cu a nuclear reaction was measured by the stacked-foil technique up to 30 ...

Gallium labeled NOTA-based conjugates for peptide receptor-mediated medical imaging [PDF]

, 2010
We report a straightforward and efficient synthetic strategy for the synthesis of three model glycine-arginine-glycine-aspartic-glycine (GRGDG) conjugates based on derivatives of NOTA and of their Ga(III) complexes targeted to the integrin αѵβ₃receptor ...

Diazirines Beyond Photoaffinity Labeling: A Comprehensive Overview of Applications in Biological Sciences, Materials Chemistry, and NMR‐Spectroscopy

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.

Radioiodination of Two Carborane‐Based Dual Cyclooxygenase‐2/5‐Lipoxygenase Inhibitors and Their In Vitro and In Vivo Evaluation

ChemBioChem, Volume 27, Issue 7, 14 April 2026.
Two dicarbadodecaborane(12)‐based dual cyclooxygenase‐2/5‐lipoxygenase (COX‐2/5‐LO) inhibitors were 123I‐labeled. Refinement of labeling and formulation conditions and extensive in vitro characterization are presented. Cell uptake studies in COX‐2‐ and 5‐LO‐overexpressing cell lines showed COX‐2‐independent and partly 5‐LO‐dependent uptake.

Mapping CSC‐Mediated Ovarian Cancer Chemoresistance via CXCR4‐PET to Guide Precision Cisplatin Re‐Sensitization Therapy

Advanced Science, Volume 13, Issue 19, 2 April 2026.
CXCR4 functions as a potential cancer stem cell‐associated marker linked to chemoresistance in ovarian cancer, and an inhibitor of CXCR4, AMD3100, can enhance the cytotoxic response to cisplatin. Based on these findings, [68Ga]Ga‐Pentixafor positron emission tomography enables selective visualization of CXCR4‐high ovarian cancer, while AMD3100 combined

2D Iron Oxide at the Graphene/SiC(0001) Interface

Small Methods, Volume 10, Issue 8, 22 April 2026.
2D iron oxide was successfully formed via intercalation of Fe and O into the graphene/SiC(0001) interface. Atomic‐resolution electron microscopy revealed that the 2D iron oxide is encapsulated by graphene and sharply interfaced with SiC. This material is suggested to exhibit antiferromagnetic behavior at low temperatures.

Dry and humid heat acclimation induces similar adaptations and cross‐acclimation benefits in trained male cyclists

The Journal of Physiology, Volume 604, Issue 7, Page 2757-2777, 1 April 2026.
Abstract figure legend Adaptive responses to hot‐dry and warm‐humid heat acclimation. Abstract This study compared adaptive responses and cross‐acclimation between dry and humid heat acclimation (HA). In a cross‐over design, trained males completed a heat stress test in hot‐dry (Dry‐HST: 42°C, 25% relative humidity [RH]) and warm‐humid (Humid‐HST: 33°C,
