Stable BF2 Boracycles as Versatile Reagents for Selective Ortho C–H Functionalization

Angewandte Chemie, Volume 138, Issue 8, 16 February 2026.
We report a robust, metal‐free and scalable synthesis of stable BF2 boracycles via directed ortho CH borylation, delivering isolable, shelf‐stable reagents without chromatographic purification. These BF2 boracycles exhibit unique and tunable reactivity, enabling highly selective ipso‐functionalization across a broad range of transformations.

Radiation‐Resistant Kr‐Selective MOF With Record Kr/Xe Selectivity at Elevated Pressure

Advanced Science, Volume 13, Issue 41, 22 July 2026.
ABSTRACT The separation of Kr/Xe from spent nuclear fuel off‐gas is critical, yet most current adsorbents exhibit Xe‐Kr co‐adsorption under elevated pressures, posing challenges for industrial pressure swing adsorption processes. Herein, we present and evaluate a metal‐organic framework, CALF‐20M‐w, engineered for molecular sieving separation of Kr/Xe ...

Correlation of Positron Emission Tomography and Low‐Field Standing Magnetic Resonance Imaging in Horses With Forelimb Lameness Localized to the Foot

Veterinary Radiology &Ultrasound, Volume 67, Issue 4, July 2026.
ABSTRACT Low‐field magnetic resonance imaging (LF‐MRI) and positron emission tomography (PET) imaging can be obtained in the standing horse. There is potential for increased diagnostic capacity combining PET with MRI, given that PET assesses the metabolic activity of injured tissues, whereas MRI provides structural and functional details on both bone ...

DOES PET/CT WITH 18F-FLUOROESTRADIOL (18F-FES) CONTRIBUTE TO THE ASSESSMENT OF BREAST CANCER COMPARED TO FLUORINE-2-D-DEOXYGLUCOSE (18F-FDG)?

Hematology, Transfusion and Cell Therapy
Introduction/Justification: While fluorine-2-D-deoxyglucose (18F-FDG) PET/CT is commonly used in the assessment of breast cancer, it has limitations, such as its inability to distinguish it from inflammatory and infectious conditions.

Fluorine‐18 Fluorodeoxyglucose‐Positron Emission Tomography/Computed Tomography for Detection of Lymph Node Metastasis in Canine Mast Cell Tumour

Veterinary and Comparative Oncology, Volume 24, Issue 1, Page 197-207, March 2026.
ABSTRACT Lymph node (LN) metastasis has been associated with shorter survival times in dogs with mast cell tumour (MCT), and treatment of metastatic LN with lymphadenectomy or irradiation has been demonstrated to improve outcomes. Identification of metastatic LN in dogs with MCT is therefore of both prognostic and therapeutic significance.

Exploring CPP Enhanced Hypoxia Targeting: An Approach Using Radiolabeled 2‐nitroimidazole TAT Conjugate

Drug Development Research, Volume 87, Issue 1, February 2026.
ABSTRACT Mediated by their protein transduction domain, cell‐penetrating peptides (CPPs) have been widely explored for facilitating intracellular delivery of drugs and small molecules. In this study, a radiolabeled, 2‐nitroimidazole conjugated TAT (TAT ‐ transactivator of transcription) peptide was prepared and evaluated for targeting tumor hypoxia ...

Integrating Nuclear Medicine Services Into Health Care Systems in Low‐ and Middle‐Income Countries: A Review of Challenges and Innovations

iRADIOLOGY, Volume 4, Issue 1, Page 3-12, February 2026.
Nuclear medicine is capable of solving noncommunicable diseases in LMICs but poses its own challenges. Research and investments are still needed. For nuclear medicine to answer the dynamics of noncommunicable diseases in the LMICs, it would have to overcome the high costs and regulations involved in this practice.
